In May, a two-week metalworking internship was held at the campus of the South Campus. During the period, we contacted 7 types of work such as sawing, boring, boring, drilling, turning, milling and planing, and also briefly understood the machining technology of CNC tools. Every day, everyone has to learn a new technology, and in the 6-hour internship time, complete the process of knowing nothing about each type of work to produce a finished product. Under the patient's patience and meticulous cooperation, we did not have an injury accident, basically met the expected internship requirements, and successfully completed a three-week cognitive internship.

Seriously, at first I felt that the three weeks were really long, but the time was rushing. I flew in three blinks. Now I think about the three-week trip to the blue collar. I tasted it: acidity - strict commuting and working system. Tired - hand-held sickle keeps licking; spicy - high-speed cutting performance; more sweet - hand-made beautiful pieces.

When we went to the South Campus, the first thing we learned was the fitter. The fitter was a manual-based processing method with high labor intensity, low production efficiency, and high operational technical requirements. However, the tools used by the fitter are simple, flexible and adaptable, and can perform some inconvenient or difficult work. Therefore, in some machining and repair work, the fitter is still an indispensable important work.

It was a little excited to go into the fitter processing workshop for the first time. On the first day, the teacher introduced us to the main equipment of the fitter. We realized the clamp table, the vise, the scribing platform, the drilling machine, and various measuring tools and marking tools. After knowing this, the teacher began to introduce the use of saws and saws. After the professor finished, we assigned us a job and asked us to cut a piece of 1 mm thick piece. This is our job. I heard this and suddenly stopped. 1MM? How can it be sawn out? The teacher said, if not how to test our true skills? When the first sawing, because the operation is not skilled, I saw the sawing road, broken, and practiced After two times, I mastered the essentials of the operation, and saw a satisfactory sheet and finished the homework!

In the following week, the teacher asked us to manually grind an iron block into a hex nut through a tool such as a file or a hacksaw. Then, through the steps of punching and tapping, we finally made a beautiful nut. There are also two sets of matching. Crafts. I remember when the nut was first made, the teacher told us that the size of the workpiece must be accurate. If the size exceeds the tolerance range of 01.MM, then 1 point should be deducted from the score. After listening to these, I was worried that I had made the hex nut small. When I saw it from the cylinder, I saw the thickness saw 2MM, and then polished it with a trowel. At first, I thought that the thickness of 2MM couldn't be anything, and it could be worn away very quickly. I didn't expect it to be worn. The thickness of 2MM actually cost me two hours. At that time, I understood a truth: the original 2MM can Equivalent to 2 hours. The most unfortunate thing was that after a while, the diameter of a pair of hex nuts on the opposite side was grounded by 0. 1MM. Looking at the semi-finished product that was not satisfied with the disability, I decided to give it up and come back! But when I look I am almost ready to go to other students. I have to flatten the uneven section of the iron column, cut it again, smooth the section, draw the line, repeat the processes, and start to worry! I really want to give up, I don't want to do it. But I am not willing to pay the defective product. At the same time, I remembered a friend who said to me: Do one thing, concentrate on it, and think that you must do it well. I will be able to do it! I said to myself, calm down, have time, and can finish my homework! When I did it for the second time, I learned a lot, and every step was extremely careful, as precise as possible, perhaps because of The operation skills have improved and the efficiency has improved. The speed of the second production is obviously higher than that of the production. It is also much better, and perhaps the first experience. After hard work, the homework was finally completed within the specified time.

After eating this loss, I also learned it. In the later homework, I carefully calculated it. I carefully followed the steps of the teacher and carefully and carefully. After a few days of practice, the efficiency has also improved a lot, the craftsmanship has become more and more precise, and the aesthetic coefficient has also increased. But in a few days, although many students have blistering on their hands, they are sore, but they see For the first time in my life, I processed the finished products in the factory. Everyone couldn’t help but feel a sense of accomplishment. We were so happy and happy. After the internship is completed, the next is a machining internship. We are no longer just sitting in the classroom as steady as we used to, watching the teacher's plan and portrayal, thinking hard: What is a lathe? Now it's a big difference, when the images on those textbooks When the machine depicted in the teacher’s class is really in front of us, we are extremely excited. Seeing those guys who have been thinking hard in their minds but can’t see their true face, we are very happy and think of us again. Not only can we see them, we can touch them, but we will also learn how to manipulate them. In addition, we will learn how to calculate the meta-control tool machine. The joy in our hearts is even more difficult to say.

Now the teacher teaches us how to operate the lathe, the bed, the milling machine. Through the study, we have all made our own crafts and completed the homework assigned by the teacher. In the machine tool that was learned, the highest risk factor was the lathe, and the turning tool was spinning at a rapid speed, but we were all careful and carefully followed the teacher's instructions and safe operating procedures. In one day, the students must first master the essentials of driving the lathe, and then follow the drawings to request the step shaft and other operations, but we learned very easily. After several exercises, we have already got the crafts that meet the requirements.

Time is like running water, three weeks is fleeting, and the three-week metalworking internship gives me the experience:

1 Through this internship, we learned about the production methods and processes of the modern machinery manufacturing industry. Familiar with the main forming methods and main mechanical processing methods of engineering materials and the working principle and typical structure of the main equipment used, the use of measuring clamps and safe operation technology. Understand the knowledge of mechanical manufacturing processes and the application of new processes, new technologies and new equipment in machinery manufacturing.

2 It has preliminary independent operation skills in the main forming and processing methods of engineering materials and main mechanical processing methods.

3 Develop, enhance and strengthen our engineering practice, innovation and innovation capabilities in understanding, familiarizing with and mastering certain engineering basics and operational skills.

4 This internship, let us understand that we must be careful and meticulous in doing things, and we must not be sloppy. At the same time, we have cultivated our strong and unyielding essence, and will not give up the perseverance in the last second!

5 Cultivate and exercise labor perspectives, quality and economic concepts, strengthen the observance of labor discipline, observe safety technology rules and protect the national property, and improve our overall comprehensive quality.

6 Throughout the internship process, the teacher has strict requirements on our discipline, and has developed a student practice code. At the same time, it has strengthened the requirements of cleaning the airport site and complying with the safety operation rules of various types of work, which has improved the comprehensive engineering quality of students. Promotion.

Soon we will step into the society and face employment. The employment unit will not tell us the work to be done in a nuanced manner like a teacher. More is that we need to observe and learn by ourselves. Without this ability, it will be difficult to meet the challenges of the future. With the rapid development of science and the wide application of new technologies, there will be many areas that we have never touched before. Only dare to try to make breakthroughs and innovations. Just like the car workers we are exposed to, although it is very dangerous, it requires every student to operate and to make finished products, thus exercising the courage to dare to try. The three-week metalworking experience brought us not only the operational skills we have come into contact with, but also the ability to exercise through several types of work, and more of us need each of us after the internship. According to my own situation, I will feel, rethink, be self-satisfied, and gain something, so that this internship has achieved his true purpose.

Part 2: Summary of Metalworking Practice

Metalworking internship is a practical and practical technical basic course for students majoring in mechanical engineering. It is an effective way to cultivate students' practical ability. As a student of electrical engineering, we do not require strong mechanical operation ability, but we also need to have certain learning ability and basic knowledge for common common equipment, in order to achieve a comprehensive and balanced development in social practice activities, and also for the future. Put a certain foundation of practical operation.

"Metalworking Internship" is a practical technical basic course. It is an important compulsory course for engineering students in engineering colleges to learn the basic techniques and techniques of mechanical manufacturing and complete basic training. It not only allows us to acquire the basic knowledge of mechanical manufacturing, understands the general operation of mechanical manufacturing, improves its operational skills and hands-on ability, but also strengthens the theoretical and practical training, improves engineering practice ability, and cultivates engineering quality. .

Due to the holiday on New Year's Day, we only conducted a 9-day metalworking internship. During the period, I was exposed to 15 types of work such as milling, PLC, car, welding, casting, rapid prototyping, mold, wire cutting, electric spark, stamping, and fitter. Every day, everyone has to learn a new skill. During the internship period, the process of making a finished product from the ignorance of each type of work is completed. Under the patient's patience and meticulous cooperation, we did not have an injury accident, basically met the expected internship requirements, and successfully completed the 9-day metalworking internship.

In the internship internship, we know that the main contents of the fitter are scraping, drilling, tapping, sawing, boring, assembling, scribing; understanding the construction, classification, selection, boring posture, boring of the boring tool Method and quality testing. The internship of the fitter is very boring. It may be a morning, but it is a reversal of an action, but also a force, but also to do it, that is, holding the sickle on the workpiece back and forth, noon break At the time, the whole person's hands were sore and sore, and the legs also stood a little stiff. I finally got the work out in the afternoon. Although it is not very standard, it is the result of my sweat and the result of my struggle in the day. The next type of work is casting, which can be said to be the aftertaste of playing with sand for hours. But this time, besides that impulsive heart, what is more needed is to be careful and patient. Later, I learned the CNC EDM, which also needs to be programmed. However, it is automatically programmed by the computer. As long as you input the part graphics that need to be processed, you can choose the path of the tool and put the raw materials. Then, we learned arc welding under the guidance of the teacher. After half a day of arc welding practice, we did not fully grasp the arc welding, but we also learned and learned a lot about the basic operation of arc welding. We mainly master the friction arc. After that, I also learned a lot of interesting kinds of work, such as rapid prototyping, wire cutting and several cars. Among the three types of work, I was able to complete my work. I was very pleased to see the work I designed and completed myself.

Time is like running water, and two weeks are fleeting. The experience of the two-week metalworking internship is:

I. Through this internship, we learned about the production methods and processes of the modern machinery manufacturing industry. Familiar with the main forming methods and main mechanical processing methods of engineering materials and the working principle and typical structure of the main equipment used, the use of measuring clamps and safe operation technology. Understand the knowledge of mechanical manufacturing processes and the application of new processes, new technologies and new equipment in machinery manufacturing.

Second, in the main forming processing methods and main mechanical processing methods of engineering materials, with preliminary independent operating skills. Third, in the process of understanding, familiarizing with and mastering certain engineering basic knowledge and operational skills, we have cultivated, improved and strengthened our engineering practice ability, innovation consciousness and innovation ability.

Fourth, this internship, let us understand that we must be careful and meticulous in doing things, and we must not be sloppy. At the same time, we have cultivated our strong and unyielding essence, and will not give up the perseverance in the last second!

Fifth, cultivate and exercise the labor perspective, quality and economic concepts, strengthen the observance of labor discipline, abide by safety and technical rules and the consciousness of caring for state property, and improve our overall comprehensive quality.

6. Throughout the internship process, the teacher has strict requirements on our discipline, and has formulated a student practice code. At the same time, we have strengthened the requirements for cleaning up the airport, obeying the safety procedures of each type of work, and have improved the comprehensive engineering quality of students. Good promotion.

The two-week metalworking experience brought us not only the operational skills we have come into contact with, but also the ability to exercise through several types of work. More people need us to work after the internship. According to my own situation, I will feel, rethink, be self-satisfied, and gain something, so that this internship has achieved his true purpose. The metalworking internship life is over, and our metalworking internship has also drawn a successful conclusion. Thanks to the school for providing us with such an opportunity. At the same time, we must deeply thank our teachers. We have benefited a lot from their words and deeds. I didn’t understand anything at the beginning, and now I have a deep understanding of various machines and have some basic operations. I believe that this metalworking internship will help us step into the society and start a business. This metalworking internship is unforgettable.

Part 3: Summary of Metalworking Internship

After a week of metalworking internship, I finally ended the subject. In this internship, I have benefited a lot and I feel a lot. While understanding the working principle of the machine, we must also understand the purpose and existence of the various mechanisms of the machine. Although in a short period of time we only have a rough understanding of the operation process and experimental principle of the machine, we are able to reach out to us. At the same time, the metalworking internship is a practical basic course, which is an important practical teaching link in the non-machine related professional teaching plan. It has great significance for cultivating our hands-on ability. It also allows us to understand the traditional mechanical manufacturing process and modern mechanical manufacturing technology.

Now as a student in mechanical automation, I am also very important to learn the theory while at the same time. Just like many college students nowadays, there are usually few opportunities for self-employment and poor hands-on ability. It is difficult to adapt to the needs of the society for comprehensive talents in the future. The metalworking internship course gives us the opportunity to exercise practically. Let us walk out of the classroom and do it yourself in the workshops of various workpieces and machines. I also want to thank the school for providing us with such opportunities. I am also grateful to the teachers who have led and guided us to study. In the days when I was a blue-collar, we had hardships and fears, but we gained more happiness and valuable hands-on experience. The kindness and experience that the teachers and classmates gathered in the workshop are the eternal memories of my life.

During the internship, we participated in casting, mold, fitter, general car, number milling, welding, grinding. I learned a lot of valuable things from it. It taught me what I couldn’t learn in books and enhanced my hands. The ability, although there is a certain degree of danger in some internships, is very happy and satisfying to be able to complete the work alone. In the first day of the internship, we started casting first. The teacher said that casting is the beginning of all the processes, so we all feel very honored to be the first group. It is very handy for modeling with sand. Activity, because for these sands, we have to hammer with a balanced force. Too much force will cause the sand to be dense. It will cause pores in the formation of molten iron and other solutions. The force is too small, the molten iron will flow out, and the shape will not be formed. So hammering a day of sand is also very tiring, but I also understand the origin of the items in our daily necessities.

After casting, it is a stamping internship. This internship is relatively simple, but the degree of danger is larger than before, and the machine is relatively large. The purpose of stamping is to make a small groove or puncture, to prepare for the next step or Decorative. Then I went to the mold internship. There is no machine in this project. I use the measuring instrument to measure the distance, etc., and then make it into a three-view image. Although I don’t need to operate the machine, I am tired of myself. The hand has been drawing, and the time is also more, it is given to us in 2 days to complete. After the mold began to go to dangerous projects, the next is welding, the clothes of many classmates in our class are all bad here, this is not the focus, the focus is that our skin has different degrees of injury, at the beginning At the time, we first practice gas welding. This project is a combination of acetylene and oxygen and steel wire bonding for welding. However, during the bonding process, some small explosions occur due to the generation of oxides. In the case of Mars in the past, there were many holes in the Mars that fell on the clothes. After that, the gas is cut. The danger of this internship is not limited to Mars. It is because the oxygen is too much and the temperature is high. It is easy to spray the molten iron. This damage is one piece, so be careful and sometimes A sizzling explosion. After the end of gas cutting, it is electric welding. This internship is the most harmful to the skin in all internships. Because our class, in addition to the cleverly dressed long-sleeved classmates, all of them are recruited, and skin peeling occurs on the arms and chest. And the redness, this internship is the safest, because the protective tools are quite adequate, but the light emitted during work is indeed stronger than the ultraviolet light. It feels nothing to start at the end of the internship, but the damage is slow after 2 or 3 days. Slowly emerging, this is also my most internship project.

The next step is to go to the general car. The machine operation of this project is really similar to that of the car, because the control of the operation of the machine depends on several rings, and these rings are the appearance of the workpiece that you decide to process. Control the general car must be gradual, do not be too hasty, or it will destroy the appliance, etc., in serious cases, it may hurt its own safety, the parts processed with the general vehicle are accurate to 0.1 mm, so carefully observe and process The consequences of the accident are very serious, and another purpose of the metalworking internship is to train students to pay attention to safety while operating, so as to avoid accidents due to operational problems in future work.

After the general car to the general milling, this project as long as the plane is milled, the operation is similar to the general car, but the control components are different, although we have been exposed to large machines, but the teacher is still inevitable over and over again, be careful , work in order, can not step into the sky. In this project, we also saw the most expensive machine, 180,000, although it looks like the other 70,000 machines, but the teacher said that its hydraulic system is different from other, it is expensive here.

This is followed by grinding. This project is the most important thing to be careful, because the grinding wheel rotates very fast, so the infeeds are one-tenth the distance of the previous machining. It is necessary to be at this length to ensure the safety of the machining, although this is better than other. It has been processed several times, but the parts that have been processed through it will have a smooth side and feel very good. In the end, it is the real labor hard work, this project is the longest, because the internship content is to use a variety of tools to polish, flatten, and cut into a little girl, this is The end of the nightmare of the internship, because the whole process of this internship was caused by hand, it only took a lot of time to smooth the two end faces, and it was necessary to grind the original 18X18 into 17X17. This operation is very hard, although the teacher said In order to complete the students quickly, the steel bars were replaced with low carbon steels, but it is difficult for us to contact these small crafts for the first time. Although these are hard work, we have no way but only according to the school. The requirements are top-notch, these are just very quality, grinding for 1 hour before going to 0.3 mm, in this hour, we are always repeating the same action, always grinding, frustrating, sawing, It feels like these have become part of our lives, although there are still breaks. It’s very boring to say the truth to the fitter. It’s possible to do it in the morning, but it’s a reversal of an action. It’s also a matter of strength, but also to do it. That’s the way to hold the file back and forth on the workpiece, until noon. The whole person's hands are sore and sore, and the legs are also standing stiff. However, when I am tired, I can see the teacher guiding me and demonstrate it myself. He is also full of sweat and panting. Seeing this often gives me motivation. But for this project, the students have already felt numb to it, just hope that the sport can end the project quickly. After three days, the hammer is definitely doing well. Looking at my own processing results, what we want to say most is to thank the teacher who guided us, but the scars after work are also obvious, you will find more in the palm of your hand. A few blisters, this is evidence that you have been working for many days, and there are some scratches on your hands. This also shows our understanding and understanding of the blue-collar work. It also shows that we are in this regard. The shortcomings.

Through this metalworking internship, I feel that the actual production method is still relatively backward, because the books are all advanced equipment, which is aimed at mass production, and the equipment in our internship is often characterized by labor intensity. The technology content is low, but there are still some basic knowledge that can be applied in practice. As a college student, we have experienced theoretical research for more than ten years. We are often told that there is a gap between theoretical knowledge and practice, but we are not. Proof of law. The metalworking internship gave us a chance to practice, leaving the rigorous environment of the classroom, we felt the atmosphere in the workshop. We have felt the importance of hands-on ability in the classroom for a long time. Because we can't complete the actual work only by thinking and figuring in the brain, we must have the ability to master practical skills, including the continuous accumulation of mechanical operations and experience. Knowledge is applied flexibly and effectively to practical work. The end of the metalworking internship also indicates that our blue-collar trip has also drawn a successful conclusion. Thanks to the school for providing us with such an opportunity, but also to thank our teachers deeply, we have benefited a lot from their words and deeds. . This metalworking internship is very unforgettable. It brings us not only the operational skills we are exposed to, but also the ability to exercise through several types of work. More Everyone needs to be sensible according to their own situation after the end of the internship, to reflect, to be self-satisfied, to gain something, so that this metalworking internship has achieved its true purpose, and is also a good opportunity to enrich the students.

After the general car to the general milling, this project as long as the plane is milled, the operation is similar to the general car, but the control components are different, although we have been exposed to large machines, but the teacher is still inevitable over and over again, be careful , work in order, can not step into the sky.
