Chapter III Internship Experience

Production practice report

Production practice is an important part of university practice, and the school attaches great importance to it. Every year, a large amount of funds are allocated to arrange students of various majors to visit and practice in various factories, so as to increase students' knowledge, consolidate textbook knowledge, let us know some basic operation processes of the factory and lay a solid foundation for future study and work.

Of course, our major is no exception. Three weeks before the start of school, the school arranged for our professional students to participate in production practice. Under the leadership of Mr. Wang and Mr. Jing, more than 50 of us went to Jiaozuo No.3 Ceramics Factory and Luoyang for practice respectively, and learned a lot.

Through my own visit, I also searched all kinds of books and related materials online, consolidated and improved my knowledge, and successfully completed this internship report. Because we visited two different factories in two periods, the content of this report mainly includes three chapters.

Chapter 1: Practical Course of Ceramic Factory.

Chapter II: Yi Tuo's internship process.

Chapter three: Thinking about practice.

Chapter I Practice Course in Ceramic Factory

Part I: Introduction of Huatai Ceramic Factory.

The enterprise has been awarded the honorary titles of "Honest Unit", "Contract-abiding Unit" and "Quality Management Standard Enterprise" by the state and provincial and municipal governments for many times.

At present, relying on reliable quality and consistent reputation, our products have been exported to dozens of countries and regions such as the European Union, the United States, Canada, Australia and Southeast Asia. Our sales target is "Let every country in the world have our products".

Enterprise spirit is "learning with an open mind and doing things with integrity". We will learn advanced technology and experience at home and abroad, carry forward China's traditional ceramic culture, and make friends at home and abroad. Welcome investment and common development to add luster to China ceramics.

Part II: Brief introduction of ceramics.

Ceramics has a long history in China and has been regarded as excellent decorative materials since ancient times. Ceramic art is the art of condensation of fire and earth. China's ceramic craft is rare in the world because of its exquisite production art and long historical tradition, and will always be worthy of our future generations' admiration, learning and pride. With the development of modern science and technology and the improvement of people's living standards, especially in recent years, due to the excellent performance of ceramics, people pay more and more attention to ceramics, and there are more and more researches on ceramics. In-depth, the application of ceramics is more extensive, and the varieties have also changed a lot.

Any object made of clay with different properties, such as pottery clay and porcelain clay, through the technological processes of batching, molding, drying and roasting, can be called ceramics. There are many kinds of raw materials for making ceramics, not only the differences between pottery and porcelain, but also the different properties, characteristics, textures and colors of various raw materials. The most important things are pottery clay, porcelain clay and glaze.

Ceramic products are widely used in construction, chemical industry, electric power, machinery and other industries as well as daily use and decoration because of their simple production process, rich and cheap raw materials, high compressive strength, high hardness, high temperature resistance, corrosion resistance, insolubility in water and easy molding. However, there are still some shortcomings in the production of ceramic materials, such as fragile quality, poor ability to withstand impact, stretching, bending and shearing, time-consuming sintering, high energy consumption and large space occupation. In recent years, with the continuous improvement of production technology, the ceramic industry is still developing, and the uses of ceramic products are becoming more and more extensive.

There are many kinds of modern ceramics, mainly including the following:

Building ceramics: including porcelain brick, mosaic brick, fine stoneware brick, imitation brick, glazed tile, split brick and glazed tile. The products have good durability and corrosion resistance, and there are many varieties and specifications (the side length is between 5cm- 100cm), which are mainly used for the decoration of internal and external walls and indoor and outdoor floors of buildings.

Sanitary ceramics and bathroom products: including washbasin, toilet, shower, washer, sink, etc. These products have good stain resistance, thermal stability and corrosion resistance, and come in various shapes, colors and specifications with complete equipment. Mainly used as sanitary facilities in bathrooms, kitchens, laboratories and other places. In addition, there are enamel bathtubs, acrylic bathtubs, bathrooms and other bathroom products.

Art ceramics: including pottery figures, pottery animals, microplastics, utensils, etc. The products have vivid images, high artistic value and diverse styles and specifications. Mainly used as indoor art furnishings and decorations, it is treasured by many collectors.

Garden ceramics: including Chinese and Western glazed products and flowerpots. The product has good durability and artistry, and is available in various shapes, colors and specifications. In particular, the tiles, ridges and decorations of glazed tiles in China are fully matched and used as the decoration of garden-style buildings.

Household ceramics: including stoneware and ceramic casserole. The product has good thermal stability, basically lead-free cadmium dissolution, and many styles and specifications, and is mainly used in restaurants and cookers.

Special ceramics: mainly ceramic rollers. Ceramic roller has good high temperature performance, with diameters of 4cm and 5cm and length of 200cm-400cm. It is mainly used for supporting and conveying blanks when ceramic tiles are dried and fired.

Mechanical ceramics: including ball mill, spray drying tower, brick press, roller kiln and other complete sets of equipment for building ceramics production.

Part III: Visiting the internship process.

On September 8th and 9th, 2006, a group of more than 50 people majoring in industrial design in our college, led by Mr. Wang and Mr. Jing, came to Jiaozuo Ceramic Factory with excitement. This is another world of our school, and there are countless workers everywhere. They are doing their jobs dutifully. Their actions are so skillful and serious that they deeply infected me, set an example for my future work and taught me how to treat them in the future.

After that, we were taken into a small conference room. Later, a middle-aged master came to give us a lecture. He introduced us to the ceramic factory, mainly the production and processing technology of ceramics, and briefly talked about the matters needing attention during the visit.

This factory mainly produces daily-use ceramics, so most of what we saw during our visit were plates, bowls, cups and so on. But we basically didn't see anything else. Moreover, all the products of this factory are exported abroad and sell well. In addition to the product itself, it is also an important reason why foreigners have always admired China culture.

Later, we visited various production workshops under the guidance of a middle-aged master. Under his explanation and his own observation, and by consulting various materials, I learned about the processing technology and manufacturing process of ceramics.

The fourth part: the molding technology and production process of ceramics.

The general ceramic molding process refers to the production process of making pottery, stoneware, porcelain and other ceramic products with clay as the main raw material through molding and roasting. Due to the development of modern inorganic nonmetallic materials science, the raw materials of ceramic products are no longer limited to traditional natural mineral materials. Therefore, in a broad sense, ceramic molding includes not only the molding of the above-mentioned ordinary ceramic products, but also the molding of some special ceramic products (such as high-alumina porcelain, magnesium porcelain, zirconium porcelain, magnetic porcelain, cermet, etc.). ) contains little or no clay and uses synthetic materials.

After the raw materials of blank glaze enter the factory, they are carefully selected and washed, and the ingredients are weighed according to the production formula. After ball milling and fine grinding, iron removal and screening are carried out. Then, according to the different molding methods, the machine-made molding adopts mud pressure filtration dehydration, and the mud is refined in vacuum for later use. The pulping process is as follows: firstly, the slurry is filtered and dehydrated, then coagulant is added for pulping, iron is removed and screened for later use; The slurry for grouting molding is processed by vacuum to become the finished slurry for later use.

Forming technology: it is divided into rolling forming and grouting forming. And then dried and trimmed for later use.

Sintering process: after obtaining the white blank, it is fired in the kiln, and after finishing, glazing and glaze firing, the white porcelain after leaving the kiln is selected to obtain qualified white porcelain.

Color baking process: after the qualified white porcelain is decaled and inlaid with gold, it is roasted in the flower baking kiln, and after the kiln is opened, it is inspected and selected to get the qualified flower porcelain products.

Packaging technology: the flower porcelain is packaged according to different collocation methods and various requirements, that is, the final product of the company is molded, delivered from the factory or put into storage.

The second chapter is the process of dragging internship.

With excitement, we arrived at the beautiful "Ancient Capital of Nine Dynasties" Luoyang, lived in the dormitory arranged by Yi Tuo, and started a new journey.

Part II: Internship process.

(1) safety education

On September 1 1, 2006, we arrived in Yi Tuo successfully. After all the arrangements were made, we took a walk in the street. Just looking at this beautiful city, everything is new to us. Unlike Jiaozuo, she has more cultural charm than Jiaozuo, and then we are ready to eat. We found something that Jiaozuo didn't have, and then went back to our residence to wait for the safety education in the afternoon.

In the afternoon, safety education began. The teacher showed us safety production records and accident cases, and added some precautions with bloody cases. Although I am too scared to listen and see, I can't. I have to listen, watch and take notes. These bloody cases have sounded the alarm for people. The teacher put forward a lot of requirements for us, and we must all do it. After all, no one can afford an accident.

Sandals are not allowed to enter the factory;

Pants must be worn when entering the factory;

Smoking is prohibited in the factory, and those who are found will be fined;

After entering the factory, clothes are not allowed to be opened, coats are not allowed to be hung on the body, and backpacks are not allowed to enter the factory;

Don't pile things in the factory, don't stand on the main road;

Pay attention to the image of yourself and the school;

Don't press buttons and switches at will;

Be safe! ! ! !

(2) Visit the First Assembly Plant

On the morning of September 12, 2006, led by Mr. Wang and Mr. Jing, we walked into the first assembly plant. After a master introduced the situation of the first garment and the matters needing attention in the visit, we entered the first garment production workshop. This workshop is really big, much bigger than I expected. So many machines are running at high speed, and there is a lot of noise inside. I think their working environment is quite bad, which also gives me some understanding of them. It's really hard for workers. The workers operate those machines with concentration and skill. I pay attention to the surrounding situation when I visit to avoid accidents. We really don't know much about those things, but we still take them seriously. After all, it may be useful for our future work. We also ask some questions from time to time from teachers who are not very busy and try to learn as much as possible. We mainly visited their tractor assembly line and proceeded step by step in an orderly way, which gave us a little intuitive understanding of tractor assembly. Although we don't know much, after all, we know something. One large tractor comes out of this assembly line.

At the same time, we also need to know the general situation of Zhuang Yi, which can deepen our internship effect.

Introduction of the first assembly plant: The first assembly plant of China First Tractor Co., Ltd. is located in Luoyang, Henan Province, and is the largest manufacturing base of agricultural crawler tractors in China agricultural machinery industry. The factory was founded in 1956, covering an area of 55,800 square meters and a building area of 36,600 square meters. It is the backbone professional factory of the first tractor factory, which is one of the key projects in the first five-year plan period 156. Since the assembly of the first 54-horsepower crawler tractor in China was completed on July 20th, 1958, the annual production capacity of 25,000 crawler tractors has been formed. After more than 40 years of development, Oriental Red Card tractors and construction machinery have spread all over China, and have been exported to more than 50 countries and regions such as Europe, North America, South America, Africa, East Asia and the Middle East, which have been well received by users. The first general assembly plant implemented total quality management and passed the GB/T19002-1994 _ _ ISO 9002:1994 certification on February 3, 2002. Obtained the quality system registration certificate (No.:97B 142) and quality system certificate (No.:0379B40 1) issued by the Quality Assurance Center of China Quality Management Association. The product range covers the production, delivery and service of Dongfanghong series crawler tractors. The first assembly plant pays attention to scientific and technological investment and product research and development, so that the product development ability and technological innovation ability of enterprises are continuously enhanced. In the past ten years, 15 major technical transformation projects have been realized, involving cooling, heating, painting, assembly and welding, and a new assembly line has been built, which further improves the level of process equipment and production capacity, and enhances the competitiveness of enterprises' products. Our factory has a complete set of heat treatment equipment, such as flexible machining line of machining center, gas shielded welding, imported heavy-duty vertical broaching machine, multi-axis automatic vertical lathe, multi-function controllable atmosphere multi-purpose furnace controlled by microcomputer, bright quenching, numerical control induction heat treatment, gear parts and shaft parts, and nearly a thousand modern equipment, such as shell parts, fork parts, shaft parts special production line and electrostatic coating line. The newly-built assembly line has high-tech content and complete functions, and adopts many new technologies such as industrial automatic computer monitoring, online detection, computer monitoring running-in test bed, large-screen logistics management and so on. It can realize multi-variety mixed-flow assembly and high-horsepower tractor assembly. The first assembly plant is not only the main engine manufacturer of variant products of crawler tractors and bulldozers of First Tractor Co., Ltd., but also has the ability to improve, develop and sell various variant new products of tractors. With 100 senior technicians, it can adapt to the development and changes of international and domestic markets and the different needs of users. CAD, CAPP and computer network information system (ERP) have been widely used in process design, product development and enterprise management. In recent years, we have independently developed dozens of variant products, such as crawler trailer series, hydraulic excavator series, transportation and agricultural wheeled trailer series, and special crawler machinery products, which have been well received by users. "Unity, dedication and first-class" is the spirit of one outfit. With the advent of the knowledge-based economy era in the 2 1 century, our factory is willing to carry out extensive technical, product and trade cooperation with domestic and foreign enterprises and scientific research institutions under the principle of equality and mutual benefit, revitalize agricultural equipment, strive for future development, and let the "Dongfanghong" brand spread all over the world with the songs of sing the chinese people.

(3) Visit Yi Tuo Precision Foundry.

On the afternoon of September 12, 2006, we visited Yi Tuo Precision Foundry, and the same working conditions were not very good. Through the master's explanation and own observation, it is found that the investment casting method is mainly used in the factory, and the process flow of investment casting is: making mother mold-making pressing-making wax mold-making shell-dewaxing-baking modeling-pouring-shelling. Investment casting has accurate size, smooth surface and no parting surface, so there is no need for machining or less machining. Investment casting has many processes and long production cycle. Due to the strength of the shell, the weight of the casting is generally less than 25kg. Suitable for producing small, medium, thin-walled and complex castings of various metals and alloys.

Brief introduction of Yi Tuo Precision Foundry: This factory is a professional factory of First Tractor Co., Ltd., which has a history of investment casting for 40 years and is one of the largest precision foundries in China. The spare parts of precision casting construction machinery include bucket teeth, tooth roots of various excavators and loaders, mining drills, claws, chains, and teeth of railway pillow bottom cleaners. Wear resistance and quality can be compared with imported original spare parts. The annual production capacity is 3000 tons.

I plant a strong technical force, sophisticated technology and equipment. It has the first mechanized shell-making production line in China, intermediate frequency induction furnace, casting conveyor linked with molding, gas baking, pouring and sand dropping, DV-6 direct reading spectrometer imported from Microsoft Corporation of the United States and other advanced quality inspection equipment.

Our factory has passed the ISO9002 quality system certification, and our products have won the "Jinding Award" silver award and gold award in the national foundry industry. Our products are exported to America, Germany, Japan and other countries. Among them, General Motors, a world-famous enterprise, purchased our castings and applied them to locomotive braking systems.

(4) Visit Yi Tuo No.3 Assembly Plant.

In September 2006, on the morning of 13, we visited Sanzhuang. The factory has a small proving ground. They were testing when we went. It turns out that Sanzhuang has produced a small tractor, which is very common at home. When I visited the workshop, I found that Sanzhuang was similar to Sanzhuang. It is not as big as the first one, but it produces a small one. Other processes are not much different. It didn't take long to see it, and the masters said it was too dangerous. Just look at it.

About the Third Assembly: The first BM 120 wheeled tractor jointly produced by China Yi Tuo Group No.1 Tractor Co., Ltd. and Finland Weichuang Co., Ltd. was recently assembled in the Third Assembly Plant of Yi Tuo Co., Ltd. and successfully tested at one time. This is another fruitful achievement for China to strengthen cooperation with foreign businessmen.

At the end of 200 1, China Yi Tuo No.1 Tractor Co., Ltd. and Finland Weichuang Company formally signed a cooperation agreement for high-power wheeled tractors on the principle of sincere cooperation and mutual benefit. After that, the Third Assembly Plant of Yi Tuo Co., Ltd. immediately carried out various preparatory work, actively carried out technical training and on-the-job training for employees, and made the plant fully equipped with loading capacity. In March this year, after Weichuang's high-power wheeled tractor parts arrived at the factory one after another, they quickly transferred the production technical backbone to form an assembly team. Under the guidance of Uvira, technical director of Flextronics Brazil branch, they became familiar with assembly technology as soon as possible and divided their work reasonably. After three days of United struggle, the assembly task of the first large wheeled trailer jointly produced was successfully completed. After the trial operation, it completely meets the technological requirements of Weichuang Company. Its cooperative production of large wheeled tractors not only ensures the working efficiency and reliability, but also has obvious cost-effective advantages, laying a solid foundation for Yi Tuo products to win the initiative in the fierce market competition.

(5) Visit Yi Tuo Gear Factory.

On the afternoon of September 3rd, 2006, we visited Yi Tuo Gear Factory. The hungry master in the factory told us about the factory, and then we went into the workshop. Pay attention to safety when you get here. All kinds of lathes and machine tools are rotating at high speed, which is very dangerous. We should be very careful. Here, we really came to a gear kingdom. There are all kinds of gears. I didn't count how many kinds of gears they produced.

(6) Visit Yi Tuo Mould Factory.

On the morning of September 6th+April 6th, 2006, we visited Yi Tuo Mould Factory. The scale of Yi Tuo Mould Factory is not very large, and the CNC workshop has moved out of the factory and moved to the mountains. Even now, it is not allowed to visit, because the technical requirements are relatively high, and the operators must be highly concentrated and cannot be disturbed.

Yi Tuo Mold Factory Enterprise Profile: It is a professional mold factory with forging molds, stamping molds and casting molds as the leading products, with fixed assets of more than 40 million yuan. In 2003, it passed the ISO900 1:2000: 2000 international quality certification, has the quality standard system certification, and has the ability to develop, design, manufacture and debug various mold processes. The company has more than 50 professional engineers and technicians, as well as more than 30 high-performance UNIX and NT graphics workstations. CAD/CAM adopts high-performance three-dimensional software such as PRO/ENGINEER, UG/NX, CIMATRON and HIGHMILL, and mold design and manufacture adopts full three-dimensional CAD/CAE/CAM/PDM integrated technology and reverse engineering. CAE analysis of casting manufacturability and stamping manufacturability can be carried out for irregular complex castings and stamping parts, and the process scheme can be optimized. Now it is a key demonstration enterprise of information manufacturing in Henan Province.

(7) Visit Yi Tuo Heat Treatment Plant.

On the afternoon of April 6, 2006, we visited the heat treatment plant. According to the team leader, the equipment in this factory is one of the best in the country. At first, I didn't know much about it. After going in, I found that people are not blowing, and all kinds of large-scale equipment are working efficiently, and they are all numerically controlled, which shows that the equipment is advanced. Of course we can't move, we can only watch. Actually, we don't quite understand it. We're just going to have a look and learn something.

Enterprise introduction: Since the beginning of this year, the heat treatment plant has identified the market position, worked hard on its internal strength, and constantly established its brand advantage by means of technology, quality and scale, won business opportunities with sincerity, integrity and quality service, and won the trust and support of its partners.

As a professional factory focusing on parts processing, how to establish and enhance the brand advantage of heat treatment and occupy a place in the fierce market competition? Based on the analysis of the market situation inside and outside the factory and its own development, the factory has formulated the market management concept of "leading technology and sincere service", and implemented this concept in all aspects of production, technology, management and quality management, striving to provide users with "beautiful heart and beautiful appearance" heat treatment products. Forging plants and precision casting plants are the main customers in the internal market of heat treatment plants. In order to establish a good cooperative relationship and achieve mutual benefit and win-win, the production and operation department, under the leadership of Li Jingdi, the leader in charge of the factory, took the initiative to attack, closely contacted the cooperative factories and followed the service 24 hours a day. Technical and quality departments and related workshops humbly solicit users' opinions and suggestions, and solve the problems reflected by users in time. While comparing progress, price and service, they use advanced technology and operational means to meet the different needs of users, and the variety of business development has also expanded from the original two or three to more than 60 now. 1- 1 1 The completed output value increased by 362 over the same period of last year. Axis research technology co., ltd is a newly developed heat treatment equipment manufacturer. The products produced by the company, such as shell and front cover, require high technical conditions such as heat treatment appearance and precision, and the heat treatment processing cost is considerable. In order to ensure the product quality and expand the market share of high value-added products, the factory assigned professional technicians to adjust the process, produced with advanced Italian kilns, and ensured customer satisfaction with the best quality, which further consolidated the cooperative relationship and created conditions for the product structure adjustment of the heat treatment plant in 2006.

Over the past year, the heat treatment plant has established its own brand with technology, won the support of customers with integrity, and attracted many manufacturers to form strategic partners with itself. Xuchang Jinrunda Gear Co., Ltd. transported the parts to the heat treatment plant for processing. Other manufacturers inside and outside Yi Tuo Company are also actively seeking production cooperation with the heat treatment plant, which provides strong support for the development and operation of the heat treatment plant.

(8) Free time.

September 15, 2006 is our free time. We can choose what to do, visit Yi Tuo again to get a deeper understanding, or visit other places. I chose to go to Baima Temple, Luopu Park and National Garden with my classmates.

First stop: White Horse Temple tour. Baima Temple is the first ancient temple in China. We followed a tour guide, listened to her explanation, felt the charm of this ancient temple and brought down the scenery of the ancient temple. The statue of the white horse is so lifelike that we even took many photos with it. What impressed me was the big stone pomegranate. According to the tour guide, this stone can cure all diseases. Just touch it with your hands, and then touch your uncomfortable place. But the key is to be sincere, and sincerity is spiritual. Visiting the White Horse Temple makes us feel that the ancient culture of China is so charming.

Second stop: Visit Luopu Park and National Park. I prefer natural scenery to human landscape. It is really beautiful here. Luohe is very wide. We entered the National Flower Garden from Luohe. Due to time constraints, we went directly to the lake, which is said to be beautiful. As expected, it was really beautiful after reading it. Although it is artificial, you have to admire the level of others. I like the lawn by the lake best. I have never seen such a good lawn. It's really soft Hey! Unfortunately, I have to leave again!

The internship ended like this. I have learned a lot and gained a lot!

Chapter III Internship Experience

Before going, I always thought that we should have a deeper understanding of the production situation of the enterprise according to the knowledge learned in books and classes. But after I went, I didn't know how naive my thoughts were, and I understood the true meaning of the book. "On paper, I know nothing." I also understand the teacher's good intentions, and we must go to the factory for internship. Really, there are many things that seem to have been understood, but in reality, it is another situation. Sometimes you think that what you have mastered may be only a superficial or overall aspect, or even a wrong understanding. You can't find these problems without field investigation and practice. This internship gives each of us a good opportunity to learn knowledge that books can't learn, increase our knowledge, have a certain intuitive understanding of production and operation, and have a new understanding of workers. Thanks to the leaders and teachers for giving us this opportunity to enrich ourselves and increase our knowledge!
