Summary Report on College Students' Metalworking Internship in 2019

Metalworking internship is the "first-class event" that we encountered in our junior year. She is really tiring, and has high requirements for technology and precision. For us, we are used to sitting in the classroom and listening to the teacher's lectures. For students, this course is really different. But you don't think that I hate this course. On the contrary, it is over. Going back to Kenken's hard road for ten days, I found that I stayed on the ground. A deep footprint was printed.

As a non-machine student, maybe this opportunity will be able to "close contact" with these "big guys" in this life. I think this experience is very rare.

Look at the plane I made, although the lower half of the fuselage is full of sand holes, and my hoe, although the head and the handle are not very suitable, but they are still very happy to see them, after all, it is also my witness after some efforts.

Metalworking Internship Summary Report

The two-week metalworking internship has come to a close in the metal reverberation. In general, this two-week internship is an interesting and influential experience that will affect my future work. I think that in the years to come, I am afraid that there will be no such opportunity. In a short period of time, I will fully experience the methods that are commonly used in today’s industry. I am afraid that it is difficult to have such a lucky experience to experience everything around me. How was it made?

“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. . This is a good opportunity for us to learn and exercise! I learned a lot through this short and substantial internship ...

Safety first

In industrial production, safety is the first priority and is crucial! ! This is the first advice every teacher gives us. In the industrial security subjects, we were arranged to take turns to see a video on internship safety. The video contains detailed internship requirements and safe handling of many types of work, such as electric welding, heat treatment and so on. Looking at the complicated machine that was born and operated, there were many accidents that occurred because the machine was not operated as required. We were all shocked. You never know the full extent of things until you see them! An unintentional movement or a small negligence can lead to mechanical accidents and even personal safety accidents. Before the safety incident occurred, many people did not pay much attention to safety education. They thought it was too cumbersome and too boring. Once an accident has occurred, there will be a lot of things afterwards.

After watching the video, we were in the workshop and listened to the teacher about the industrial safety. Looking at the information sent down, I understand the importance of industrial safety. Industrial safety knowledge is an essential knowledge of industrial executives and developers. For drafting or a company's safety regulations, reducing industrial pollution, fire and explosion protection, etc. It is a very important knowledge. If you don't master it, you will not only be dismissed as ignorant, but sometimes there will be major accidents. Therefore, safety is always the first priority. We are deeply in mind and do things seriously and seriously. I am very glad that I have paid enough attention to it, so I spent the two weeks of internship safely!

CNC lathe

The first type of work we did internship was the operation of a CNC lathe. It is through programming to control the lathe for processing. Through the operation and programming of the CNC lathe, I deeply felt the convenience, accuracy and speed of the digital control. As long as the correct program is input, the lathe will perform the corresponding operation. The programming requirements of the number 980 are very high, and a wrong symbol can cause several cars to run. Programming is a big problem for me. The results and the students studied for a long time, only came up with a feasible solution.

Hey, this time I know how important programming is in the application, regretting that I didn’t study hard to lay a solid foundation. It’s really "there is less hate when the book is used!"

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. That machine is so convenient, although there is no real operational opportunity, but we have seen some of the cut objects placed next to it, we have been amazed. Those badges that feel very good, let us be deeply impressed by the great power of technology!

Unforgettable turner

The lathe is not done by numerical control, it requires a high degree of manual operation.

First of all, the teacher told us to read the book while watching the lathes familiar with the various components of the lathe. The lathe is mainly made up of gearbox, headstock, hanging wheel box, feed box, slide box, knife holder, tailstock, bed, screw, light. The bar and the joystick are composed. The lathe is operated by various handles. The teacher explained to us the role of each handle, and then let us machine a workpiece with a spherical shape on both sides and a cylinder in the middle. The teacher first demonstrated the operation method and processed a part, then let us start processing. A very important aspect of lathe machining is to choose the right knife. At the beginning we have to flatten the end face of the given cylinder, we must use the partial cutter to process, then cut and machine the spherical surface, then we need to use it. Slotting knife. The grooving cutter has a small cutter head width, and has a main cutter and two sub-cutting cutters. The cutter head is small and easily broken, so that a small cutting amount is applied. When grooving, the left and right borrowing method is adopted. When the groove is cut, the spherical surface is processed. This is a test for those of us who have never used a lathe.

I kept turning the horizontal and vertical control handles, carefully processing them, and doing a whole afternoon. When I thought I was about the same time, I was ready to take the last knife, but I was too hasty to cut off the corner of the sphere! I was distressed that the product that was supposed to be successful was destroyed by myself. Miserable! In desperation, I had to narrow the radius of the ball. This time I shrank a few times and finally got out of a part that barely could be said to be a ball. The most uncomfortable thing was that I stood up all day and my calves hurt. But the joy of success when I handed the good parts of the car to the teacher made me forget the calf that stood so painful. The joy of this success is only through personal experience. I can get an experience by attending an internship .

Cast molding

The next type of work is casting, and the classmates who finished listening said that this is a difficult job! To make those sands and muds that have no shape become what we want is to make us move our brains. It needs not only our physical strength, but also our patience, not to be sloppy!

Casting molding, it can be said that it is completely aftertaste of playing sand. But this time, besides that impulsive heart, what is more needed is to be careful and patient. It seems that the simple four-step 1 made sand type 2 sand-type 3 dozen vents 4 out of the box and the mold. But if you want to make a model that makes everyone stunned, it is impossible to get through the rectification. Sometimes a wonderful pen can produce flowers, but sometimes it is because of your little repair that you can't give up! After a long day, even though we all got tired and backache, but when we saw the results of our hard work, I thought that it was not that much! It’s just that we don’t believe our own eyes, so a bunch of things can be so beautiful under our careful processing.

In just two weeks, we also had internships such as planers, injection molding, and heat treatment, all very interesting. Each type of work has different operational requirements and requirements, and the level of difficulty is not the same. During this time, although it is very early every day, sometimes it is hard to take a nap at noon, it is very hard, but the feeling of fullness can not be replaced. Some of the basic skills you have learned will also benefit us in the future.

Profound experience

Metalworking internships have both pains and joys. "The days will be reduced to the people of Sis, and they must first suffer their pains, work hard, be hungry, and become a big man!" This ancient saying is used to describe our metalworking internship. It could not be better! After a series of work, such as lathes, fitters, millers, casters, millers, etc., we finally completed this embarrassing metalworking internship course.

Now think about this unforgettable time in the past, the taste of which can only be experienced by people who have personally experienced it. By learning various types of work, we have learned a lot about the principles and processes of metalworking operations, and have mastered some of the operating techniques and methods, as well as those unfamiliar terminology that are now familiar and familiar! Although most of us will not be engaged in these tasks in the future, and even the possibility of touching them is not the same, but the experience and feelings brought by the metalworking internships are for the work and study life of each of us. It is a wealth of value. The role and influence of the metalworking internship is like the last words of the male protagonist in "American Beauty". "Some things you may not feel its value right now, but in the end it will be, everyone has such a process!"

The students who worked together also benefited me a lot. Unselfish help, sincere mutual encouragement, all the pressure to share the work, and share the joy of success. The metalworking internship is more like a collective activity, bringing us closer to each other and filling the gaps that existed. The charm of teamwork has been thoroughly revealed! There are very few opportunities for college students to get along with classmates. Thanks to the metalworking internship for giving us such an opportunity. Such activities are worth learning from the education sector.

In just two weeks, we have spent a lot of time in the internship . Although we don't have a lot of knowledge, we have learned that we need a lot of skills to learn and learn. If we don't often participate in internships in this area, we college students may only be Zhao Zuo's "paper talks" in the future. The society needs talents, and the society needs talents with the ability. Only in the new century, universities can participate in practice to ensure that they have their own position in the future social competition. I really appreciate the metalworking internship , I want to have another one!
