2019 Metalworking Internship Report

In the future, I will remember the internship I attended a few days ago. I learned a lot during the internship . Participating in social internships is something I have long thought of, because I want to go to the factory to participate in the internship and feel the most glorious feeling of labor, but I know that there is no idea but to be put into practice. So I contacted the factory very early, they agreed to my internship requirements.

Metalworking internship, also known as metalworking process internship , is a practical basic course. It is an indispensable pre-requisite course for mechanical engineering students to study engineering materials and mechanical manufacturing foundations. It is an important practice in non-mechanical related professional teaching programs. Teaching session. 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. During the ten days of the internship, we made forging, car, surface treatment, cad rapid prototyping, abrasive design, lathe, fitter, electric spark, industrial control, wire cutting. In ten days, there are new courses every day, and it is impossible for us to quickly master this course. However, a preliminary understanding of the application of this technology, as well as the basic method of use, is of great use to us. Especially in this era, the difficulty of college students' employment has become a very common problem. It is not a rare thing to vote for a resume on the job fair for two hours. Therefore, to stand out among so many candidates, you must have certain ability. , aluminum plate and our college students usually practice less, learn a lot of theory, how to apply book knowledge in practice? Metalworking internships have given us a good channel. First of all, the metalworking internship hired skilled workers who work in the factory. They have rich experience and can give us a lot of knowledge that can't be learned in books. Once again, college students are rich in theoretical knowledge of mechanics, but the practice is blind. Through the detailed teaching of the teachers, it is possible to effectively avoid safety accidents. At the same time, the metalworking internship has also opened up a way for us to develop in many aspects. For example, we are studying communication and electronic engineering, but we can see that many of our professional talents go out but do not necessarily do this work. It is possible to go to programming, The development of machinery manufacturing, and through the metalworking internship, you will have a strong interest in mechanical production, and then develop in this regard.

The aluminum plate was designed according to the teaching plan. Our college conducted a two-week metalworking internship. Although it only took a short ten-day internship time, it allowed us to understand a lot of knowledge that could not be learned in books, which enriched our horizons. Exercised our practical and hands-on skills. For some students, the metalworking internship is very hard, but for me, I think the metalworking internship is full of fun. Even if it is a very hard fitter internship, when I grind out the approximate shape of a nut, I only feel it. Sincerely, I feel very good at doing things.

Our first day of work is forging, forging is a combination of forging and stamping. It is the use of a hammer, anvil, punch or a die for forging machinery to apply pressure to the blank to plastically deform it to obtain the desired shape. And the forming method of the size of the workpiece. Because our internship work is only half a day, our goal is to block the growth cubes with a six-prism column. For the masters, this should be a common occurrence, but we have never touched it. When the hammer falls, it is always worried that the iron will fly out, and the floor will vibrate when the hammer falls, and my heart will also Follow the vibration. Say it is like this, when you do it, you can't be timid. If you look at the iron block, you should pay attention to see if the iron block is right. The hammer should be squared every time you hit it. First hit on the front and then on the side. And the top surface, the method is quite simple but very time consuming. After each tapping, the iron block should be put back into the furnace and reheated for 30 minutes. The difficulty of making 3jj4 three-dimensional luminous characters is. Then you have to hit a total of four rounds. Although our group is doing their best, the shape of the iron is not what we hope.

The third day is done with surface treatment. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. I think surface treatment is a very interesting job in metalworking. Our job is to engrave our design on an aluminum plate, and it feels like we are designing a work of art. However, the birth process of this artwork is very cumbersome. The first step is to degrease the aluminum plate. Put the aluminum plate into the sodium hydroxide for two minutes, then take it out and clean it. Then put the aluminum plate into the nitric acid and take it out again. Then put it into the sulfuric acid, called anodizing, then take it out and clean it. After that, you can color the aluminum plate. I gave my aluminum plate an orange color. The dyeing time is about five minutes. After cleaning again, blow it off with a hair dryer. The surface is moist, then waxed, and a layer of uniform wax is applied to the surface of the aluminum plate. I can draw a guitar on my aluminum plate because I like music, and behind it is Huang Jiaxuan. "I really love you." "The lyrics, after drawing the bamboo with a bamboo stick to pick up the surface of the wax, you can get the corrosion inside the sodium hydroxide, the corrosion time is about five minutes, depending on the specific situation, observe that the corrosion of the aluminum plate is sunken. Then, take out the cleaning, then put it into the nitric acid to remove the surface of aluminum hydroxide, the place where the aluminum plate is corroded will show a bright silver white The wax-covered area still retains the original color. The wax on the surface of the aluminum plate is removed by a hair dryer. If you are happy, you can also decorate the aluminum plate with plexiglass. Although it is tired for one day, the aluminum plate and the aluminum plate are I was able to bring back a craft I made myself, and it still feels very good.

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 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 realized and reflected, and the aluminum plate made this internship achieve its true purpose.

In general, the design of our internships accounted for a large part of the design, aluminum panels such as cad rapid prototyping and abrasive design, and wire cutting, etc., students with strong creative ability can always play their ingenuity here. For other students, it is also a good exercise opportunity. After all, our future work is mainly innovation, not simply copying other people's things, having our own ideas, new ideas, and getting everyone's approval, then you The things that are designed have a vitality, and the metalworking internship teaches us to know how to create.

In this internship, I was very excited. In general, I didn't learn too much technology, but I learned a lot of questions to pay attention to during the internship. I also learned how to do it during the internship. Working with the workers and working together to do one thing, the importance of cooperation is undoubted here, but the biggest is not these, but I found the direction of my future work in the internship, I will work harder until I succeed. !
