Internship process

1) Safety first. For any machinery factory, safety is always the top priority, so under the leadership of the internship teacher, we first carried out some safety education and safety issues and items to be aware of during the internship. For example, when entering the processing workshop, sandals are not allowed to enter the factory; trousers must be worn when entering the factory; smoking is prohibited in the factory. After entering the factory, the clothes are not allowed to open, the jacket is not allowed to hang on the body, and the backpack cannot be carried into the factory. People should not pile up in the factory, do not stand on the main road of production; without the permission of the intern teacher, do not allow the buttons and switches to be arbitrarily pressed;

2) Blank selection. First of all, we came to the original blank processing workshop of the parts. Under the guidance of the teacher, we learned the following knowledge. The parts are generally processed from the blank. Under the existing production conditions, the blanks mainly include castings, forgings and stampings. The casting is a part blank obtained by pouring the molten metal into a pre-made mold cavity and cooling it and solidifying. In general machinery, the weight of the castings accounts for more than 50% of the total weight of the main machine. It is the main source of the parts of the blank. The outstanding advantage of the casting is that it can be a variety of complex shaped part blanks, especially part blanks with complex internal cavities, and in addition, the castings are inexpensive. According to the master who guided us internship, our factory mainly produces blanks in this way. However, the disadvantage is that in the production process, there are many processes, the quality of the casting is difficult to control, the mechanical properties of the casting are poor, and the forging is used by impact force or pressure, and the metal blank after heating is plastically deformed, thereby obtaining the part blank. The structural complexity of forgings is often less than that of castings. However, the forging has a good internal structure and thus good mechanical properties. Therefore, it is used to make the blanks of important machine parts and tools that are subjected to heavy loads and impact loads. The stampings are the bodies obtained by plastically deforming or separating the metal sheets by using punching machines and special molds. Stamping is usually carried out at room temperature. The stamping parts have the advantages of light weight, good rigidity and high dimensional accuracy. In many cases, the stamping parts can be directly used as parts.

3) Processing workshop. When I came to the processing workshop, the first feeling I gave here was that it was too big. The workshop was divided into five parts, namely turning, milling and other processing, fitter, CNC machining, welding, almost covering all aspects of machining, probably There are five or six hundred people working on various parts at the same time. Although we have also conducted metalworking internships at school, we have done some parts and have some understanding of the machine tools, but they are really in the atmosphere of the processing parts. The big difference is that the tools of our school are all in a certain age. The new machine tools that are rarely produced in recent years are in speed. Our processing speed is too slow. To process the same part, we need The time is probably five or six times that of these processing masters, and it is impossible to carry out industrial production at all. In the process of understanding the processing workshop, I have more understanding of some processes of machining; blanks - scribing - planer - roughing - heat treatment, quenching and tempering - semi-finishing of lathes - grinding - gear processing - quenching - Grinding surface; gear parts processing technology: rough car - heat treatment - fine car - grinding inner hole - grinding core, shaft end face - grinding the other end face - hobbing - pliers - shaving - 铡 keyway - fitter - completed.

4) Assembly workshop. Any machine is assembled one after another. In the assembly shop, there are probably more than one hundred people collecting and assembling parts, and packaging, and then transferred to the storage plant. In this workshop, the workers first The collected parts are used for flying, one is easy to assemble, the assembly method, the assembly sequence, the required tools are determined; the parts are cleaned, the oil is removed, the rust is rusted, the oil is applied, and the surface is clean and beautiful after the machine is assembled. After the assembly of the product is completed, it is necessary to debug all aspects of the parts, check the flexibility and sealing properties of the moving parts, and then transfer them to the warehouse.

5) Quality assurance, sales and after-sales processing

Finally, we came to the quality inspection department. They mainly conducted random inspections on the products they produced, recorded their data, and returned to the processing workshop to modify and modify the products to better produce and store qualified products. As for the sales part, according to the sales department, due to the order-based production adopted by the company, the sales are all optimistic.

Experience in mechanical manufacturing

After nearly one week of internship, the internship really reached the first front line of the machinery manufacturing industry. I learned about the current development of China's manufacturing industry and also learned the development trend of machinery manufacturing. In the new century, science and technology It will develop faster, integrate more quickly and more closely into all fields, and all of this will greatly expand the development direction of machinery manufacturing.

In the future, mechanical manufacturing will develop into “four transformations”, namely, flexibility, agility, intelligence, and informationization. Even if the process equipment and process routes can be applied to the production of various products, it can be applied to the rapid replacement process. The need to replace the product, to make it flexible with the environment, to make the production to market the shortest time and to make the production and manufacturing flexible and flexible, as well as to make the manufacturing process material consumption, greatly reduce the consumption, high automation production The pursuit of human intelligence in the machine can only be highly integrated with the wisdom and information that mainly causes information to produce value through the power of matter and energy. Of course, the four development trends of machinery manufacturing are not separate, they are organic Combined, they are interdependent and mutually reinforcing. At the same time, due to the continuous advancement of science and technology, it will also lead to new development directions. What we saw earlier is the development of the mechanical manufacturing industry itself. However, as part of social development, it will also be more widely integrated with other industries. The importance of machinery manufacturing in the 21st century is reflected in its globalization, networking, virtualization, intelligence, and environmentally friendly green manufacturing. It will enable human beings not only to get rid of heavy physical labor, but also to liberate from the tedious calculations, analysis and other mental labor, so that more energy can be engaged in high-level creative labor, and wisdom can promote flexibility, which enables production. The system is more complete.

Experience with this internship

The end of the paper is so shallow that I know that this matter must be carried out. In the short internship process, during the internship, I used the methods of seeing, asking, and hands-on, to further understand the relationship between people at work, and to analyze the characteristics of people, the way. I deeply felt the superficiality of my knowledge and the lack of professional knowledge in practical use. Once I came into contact with reality, I realized that I knew how little I knew, and then I realized the meaning of "endless learning."

Part 2: Mechanical Plant Internship Report

After the start of the summer vacation, I stayed at home for more than ten days, and then I was introduced to a mechanical factory opened by my relatives in Shanghai for a month. The machinery factory is not very big, but the sparrow is small, but it has all kinds of machines. There are various machines for processing parts in the factory.

The machine factory opened by relatives mainly engaged in parts processing, that is to say, the customer sent a drawing of the parts. The factory will help the customer to process the parts that the customer wants according to the drawings. In addition, the factory also helps some large-scale The factory repairs some machine tools, machines. Moreover, since my major is mechanical design and manufacturing and automation, in this machine factory, I can just practice what I learned in the previous books in the factory.

In the month of the machinery factory, I really learned a lot of things, and also let me know more about my professional mechanical design and manufacturing and automation, in this month's time. I came into contact with ordinary lathes, CNC machine tools, milling machines, punching machines, sawing machines, tapping machines, electric welding, etc. Basically understand the whole process of processing a common part, knowing that a complex part is processed by one step, the part will be affected in various ways during the processing, so that the size of the part is not within the required range. This requires the processing personnel to continuously measure the dimensions of the parts with vernier calipers and spiral micrometers during the processing, and to determine what causes the dimensional deviation of the parts. These things are accumulated experience through long-term practice. . In addition, the most important part of the machined part is the tool. Using the right tool not only allows the part to be machined better, but also makes the part more precise.

Although the work of eight or nine hours a day is very tired, it has made me realize the hard work of the work and know the hardships and difficulties of parents and relatives to make money. I am no longer spending as much as I used to, and I know the savings and savings.

The summer social practice activities have come to an end, and I look back. Although I have not exercised for a long time, the impact on me is far from over. It has enabled me to walk out of the campus, step out of the classroom, go to the society, embark on the road of combining practice with practice, go to the big classroom of the society to see the world, display talents, grow talents, hone the will, and test myself in practice. Although this month's social practice is relatively hard, I don't know if it is fortunate or attachment, but when I think about it, I found out that the boring is full of hope, and the bitterness reveals sweetness. This social practice is fun, rich, and happy.

I personally experienced the process of processing a steel material into various parts. I think this is something that students who have never been to can understand. What I have experienced in this practical experience is an overall improvement of my ability. I also realize that I have many deficiencies. Long-term learning has kept me away from social practice, my ability to work is particularly weak, and my ability to withstand stress is insufficient. Perhaps with this experience, I will be more calm in the days to come to face every difficulty in life.

The new semester has already begun. I decided to combine my practice in the machinery factory with the theoretical study of the school during the summer semester to consolidate and improve my mechanical design and automation. Professional study.

Part 3: Machinery Plant Internship Report

In the last year of college life, standing in front of us is the long-awaited working society, and our hearts have begun to fly in there. We are happy, we are excited, because we can finally show ourselves on this huge stage, but we still need time to understand this society. To this end, the school arranged a production internship for me. The production internship is an indispensable part of our mechanism's professional knowledge structure and is included in the professional teaching plan as an independent project. The purpose is to enable us to obtain perceptual knowledge of basic production through internship, to link theory with practice, and to expand knowledge; at the same time, professional internship is an important channel for training and cultivating our business ability and quality, and cultivating the spirit of hard work and hard work of contemporary college students. An important way to reach out to the society, understand the status of the industry, and understand the national conditions, gradually realize the transformation from students to society, cultivate our ability to initially take up technical work, and initially understand the basic methods and skills of enterprise management; experience the content and methods of enterprise work. These practical knowledge are very necessary foundations for us to study the later courses and even the future work. In particular, there is still a big gap between China's actual manufacturing level and the level of foreign manufacturing, which inspires us to continuously strive to contribute to the great rejuvenation of China.

Under the leadership of the teacher, we went through Jingwei Textile Machinery Co., Ltd., which arrived on August 31, for a two-week production internship.

Jingwei Textile Machinery Co., Ltd.'s predecessor, Jingwei Textile Machinery Factory, was started in 1951. It was completed and put into operation in August 1954.

We can learn a lot from such an internship in a company with good prospects. Moreover, the skilled workers in the factory do not retain the technology. As long as you are willing to learn and want to learn, you can go to school.

On the morning of August 31st, we came to Jingwei Technical School. The teacher first gave us some safety education and safety matters and items to be paid during the internship. For any machinery factory, safety is always the top priority. 1. We then visited the Jingwei factory. First, we came to the original blank processing workshop of the parts. Under the guidance of the teacher, we learned the following knowledge. The parts are generally processed from the blank. Under the existing production conditions, the blanks mainly include castings, forgings and stampings. The casting is a part blank obtained by pouring the molten metal into a pre-made mold cavity and cooling it and solidifying. In general machinery, the weight of the castings accounts for more than 50% of the total weight of the main machine. It is the main source of the parts of the blank. The outstanding advantage of the casting is that it can be a variety of complex shaped part blanks, especially part blanks with complex internal cavities, and in addition, the castings are inexpensive. According to the master who guided us internship, our factory mainly produces blanks in this way. However, the disadvantage is that in the production process, there are many processes, the quality of the casting is difficult to control, the mechanical properties of the casting are poor, and the forging is used by impact force or pressure, and the metal blank after heating is plastically deformed, thereby obtaining the part blank. The structural complexity of forgings is often less than that of castings. However, the forging has a good internal structure and thus good mechanical properties. Therefore, it is used to make the blanks of important machine parts and tools that are subjected to heavy loads and impact loads. The stampings are the bodies obtained by plastically deforming or separating the metal sheets by using punching machines and special molds. Stamping is usually carried out at room temperature. The stamping parts have the advantages of light weight, good rigidity and high dimensional accuracy. In many cases, the stamping parts can be directly used as parts. After we came to the processing workshop, the first feeling that gave me was that it was too big. The workshop was divided into five parts, namely turning, milling and other machining, fitter, CNC machining, welding, covering almost all aspects of machining. There are about five or six hundred people who are working on various parts at the same time. Although we have also done metalworking internships at school, we have done some parts and have some knowledge of the machine tools, but they are really in the atmosphere of the machined parts. There is a big difference. First, the machine tools of our school are all in a certain age. The new machine tools that are rarely produced in recent years are in speed. Our processing speed is too slow to process the same part. We need about five or six times as long as these processors, and we can't do industrial production at all. In the process of understanding the processing workshop, I have more understanding of some processes of machining; billet---line---planing machine--roughing--heat treatment, quenching and tempering--semi-finishing of lathe--grinding --Gear processing -- quenching -- grinding surface ; gear parts processing technology : rough car -- heat treatment -- fine car -- grinding inner hole -- grinding core , shaft end face -- grinding another end face -- hobbing -- Clamping teeth - shaving - 铡 keyway - fitter - completed. We also visited the transfer workshop. Any machine was assembled from one after another. In the assembly shop, there were nearly 100 people collecting and assembling parts, and packaging, and then transferred to the storage plant. In this workshop, the worker master first classifies the collected parts, which is convenient for assembly, determining the assembly method, assembly sequence, and required tools; then cleaning the parts, removing oil, rust, oil, and ensuring the machine is assembled. The surface is neat and beautiful. After the assembly of the product is completed, it is necessary to debug all aspects of the parts, check the flexibility and sealing properties of the moving parts, and then transfer them to the warehouse. Quality assurance, sales and after-sales processing. The following analysis of the processing technology of the company's two main components.

The two-week production internship has ended. In the past two weeks, we have seen a lot, listened a lot, did a lot, and of course understood a lot. Here, I have a more comprehensive understanding of the technical process of machining and related typical parts. Initially understand the production process of typical mechatronic products and equipment, cultivate the ability to collect data and improve the ability to analyze problems, so that I can better learn and master the mechanical engineering expertise. In the internship, I also felt the fulfillment of life and the joy of learning, as well as the satisfaction of knowledge. Real contact with the society has enabled me to eliminate the fear of going to the society, so that I am full of confidence in the future and face the society with a good attitude. At the same time, we also experienced the hardships of work, understood the serious problems faced by current college students, and urged them to study more knowledge and lay a good foundation for their future work. Through this internship, I know the hardships of life and the joy of work. At the same time, I feel the insufficiency of my theoretical knowledge. I still have a lot of things I don’t know about in terms of machining. I need to strengthen the study of professional courses in the future. Be aware of the importance of linking theory with practice. I will work harder in life and learning in the future. This kind of learning makes me have a general outline of the machinery in my mind, so that the processing of each part is in front of my eyes. Suddenly I feel that the ancient paper has a long history, I know that this thing is going to be quite good. Reason. I believe that with these perceptual knowledge of practice, we will be able to learn theoretical knowledge more specifically in the future. Here, I would like to thank the factory for their cooperation and thanks to the careful teaching of the factory masters. For tomorrow, I will be even more Work hard!

Finally, I am very grateful to the teachers who accompanied us all the time, for us to work tirelessly to contact the internship unit, care about our lives, and give us patient guidance.
