In the last semester of the school year, we conducted a weekly goldwork internship at the Xinying Campus Engineering Training Center. During this time, we were exposed to basic operating skills and safety technology tutorials for casting, forging, welding, heat treatment, pliers, turning, milling, planing, hobbing, CNC and special machining. Every week, everyone has to learn a new technology and complete the process of producing a finished product from the ignorance of each type of work during the hour of internship. 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 week's internship.

During the internship, I learned to work as a mechanic and a blacksmith. We have made our own crafts, and each of the internships of milling, turning, and planers can make a workpiece according to the drawings. The hardest is the number of turners and fitters. The workman is the most dangerous, in the middle of the day. The students must first master the essentials of driving the lathe, and then ask for the hammer handle according to the drawings. Among all the types of work, the fitter is the most labor-intensive. Through the tools such as boring tools and hacksaws, an iron block is manually ground into a hex nut, and then through a step of punching and tapping, a fine nut is finally formed. One afternoon, although many of my classmates had blisters on their hands, they were sore, but when they saw the finished products they made in the factory for the first time in their lives, everyone couldn't help but feel very fulfilled. The experience of this metalworking internship is: 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 processing methods and main mechanical processing methods of engineering materials.

3 In the process of understanding, familiarizing with and mastering certain engineering basic knowledge and operational skills, we cultivate, improve and strengthen our engineering practice ability, innovation consciousness and innovation ability.

4 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.

Metalworking internship plays a comprehensive training role in the cultivation of our engineering quality and engineering ability, so that we must not only master the requirements of each type of work, but also establish a more complete system concept, which requires us to learn all kinds of work. The basic process knowledge, understanding of the equipment principle and work process, but also to strengthen the hands-on training, and the ability to use the process knowledge, preliminary analysis of the ability to solve simple process problems.

During the internship, the school will internship content of each type of work, such as: combining the production of steamed bread, cutting, turning, milling, fitter, planer, casting, forging, welding, etc., so that we have various processing links for mechanical products. A whole understanding. Let us understand the sequence and role of each type of work. 5

Throughout the internship process, our discipline requirements were very strict, and the student internship rules were formulated. At the same time, the requirements for filling in the internship report, cleaning the machine tool site, and complying with the safety operation procedures of each type of work were strengthened. A good promotion is achieved. 6

The training center teachers announced the scoring standards of our processed products to us, so that we have a clear understanding of the points of our products, and have a certain effect on improving our quality awareness. For our metalworking internship results, the implementation of a comprehensive evaluation system, the implementation of the usual scores of product quality and comprehensive examination results, so that we can seriously treat each type of work and each internship. In the internships of various types of work, a certain flexible time and internship content are arranged, so that students with strong hands-on ability have room to play.

During the internship, I had a deep feeling. I am very grateful to the school for providing us with this internship opportunity. It is not easy for us to experience the engineering and engineering in advance. We have acquired knowledge that we can’t get and can’t think of in the classroom. Maybe we won’t go in the future. I took this position, but the knowledge and feelings I have learned so far are unforgettable. Although the dirty spots are tired, these do not matter. What is important is that we have gained and achieved results.

I think that in the internship projects with high technology content such as digital milling and digital line, we should allocate more time, so that we can really experience the fun of high technology.

In terms of welding, I think we should introduce some advanced technology. Although it is not necessary to buy these equipments, I think we should teach some so that we can know the gap between ourselves and the world's advanced standards.

In addition, I feel that the metalworking practice class in our school should reduce some explanation time and increase some hands-on time. It is also possible to move some of the theories to the hands-on time of the students, which is more conducive to achieving our goals.

During the internship, many teachers' dedication and rigor also admire us. The teacher can help us find the errors in the program over and over again. Some programs are particularly long, but the teacher does not care about these. As long as there is a problem, you must take it out and do your best to make the students' works more perfect. Some teachers will show the classmates how to operate again and again until the students are really clear. This spirit is worth learning for each of us. I think the metalworking internship is very meaningful to me. It really adds a wonderful touch to my college life. It makes me closer to the life of skilled workers. I have grown more professional knowledge to make me realize my strengths and insufficient.

When we are employed two years later, the employment unit will not tell us as much as the teacher, and it is more necessary 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, a wide range of new technologies

There are many areas that we have never touched before, and we can only make breakthroughs and innovations if we dare to try. 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. In addition, like casters and seemingly simple disassembly and assembly, we need to carefully observe, practice repeatedly, fail to start all over again, cultivate a sense of frustration and so on. Zhou’s metalworking practice brings us not only the operational skills we are exposed to, but also the ability to exercise through several types of work. More needs to be based on each of us after the internship. I have to go to my own situation to reflect, to reflect, to be self-satisfied, to gain something, so that this internship has achieved his true purpose.

The fitter is based on manual operation and uses various tools to complete the machining, assembly and repair of the parts. Compared with machining, it has high labor intensity and low production efficiency, but it can complete inconvenient machining or difficult work, and the equipment is simple. Therefore, it is still an indispensable important work in mechanical manufacturing and repair work. Common equipment for fitters are bench work benches, bench vices, grinding wheels, etc. The working range of the fitter is scribing, boring, sawing, boring, scraping, grinding, drilling, reaming, reaming, boring, tapping, threading, assembly, and repair. The internship safety technology of the fitter is:

1 The clamp table should be placed in a place where work and light are suitable; the drill press and the grinding wheel should generally be placed at the edge of the site to ensure safety. 2 Use machine tools and tools, check frequently, and find that the damage must not be used. It needs to be repaired and reused.

When the three vise clamp tools, do not use a hammer to hammer the Taiwanese handle or steel pipe to apply clamping force.

4 When using power tools, it is necessary to have insulation protection and safety grounding measures. Wear protective glasses when using the grinding wheel. A protective net is required for processing on the tongs.

5 The blanks and machined parts should be placed in the specified position, arranged neatly and placed smoothly, to ensure safety, easy to pick and place, and to avoid scratching the processed surface.

6 When drilling, reaming, reaming, boring, tapping, and threading, the workpiece must be clamped. When machining the through hole, the workpiece should be padded or the tool should be aligned with the table slot.

7 When using a drill press, do not wear gloves and do not handle cotton yarn. When replacing tools such as drills, use special tools. Do not hit the drill chuck with a hammer.

All of the above are basic knowledge that must be understood as a fitter.

On the first day, I came to the workshop and the first part the teacher told us to do was the nut.

After listening to the teacher's request and looking at the seemingly simple picture on the blackboard, we started our internship. The first is to measure the size and draw lines and draw lines on the iron block. This work can be sloppy. If you make a mistake, it will make your parts out of size. It is also good to listen to the teacher's precautions. , slightly larger the size of the painting. Then, it was the sawing that I had unforgettable in my life. I used to think that saws were so sawed, so I dragged back and forth, no big deal, little things. But the fact is that the saw is also awkward. The saw is not a matter of three or seventy-one. It is simply dragging back and forth. If it is done, no matter how strong a person is, it will be both hands numb and two eyes. Panic, we must first adjust the direction of the kerf, according to the direction of the kerf, the saw should be with the left thumb against the saw blade to prevent the saw blade from sliding laterally, the right hand firmly push the handle, the saw blade should be tilted with the workpiece a saw The angle is about 10 degrees to 15 degrees. The saw is too large and the sawtooth is easy to break. The sawing angle is too small, the sawtooth is not easy to cut in, and it is possible to slip and damage the surface of the workpiece. When the saw is sawed, the reciprocating stroke is short, the pressure is small, and the saw blade is small. To be perpendicular to the surface of the workpiece.

At the same time, when sawing, the right hand grips the saw handle, and the left hand gently holds the front end of the bow frame. The saw bow should be linearly reciprocating, not swingable, and the pressure is evenly pushed forward, and the saw blade gently slides over the workpiece when returning. The reciprocating speed should not be too fast, and the pressure and speed should be reduced before and after the sawing to avoid hurting the arm and breaking the saw blade. A small amount of oil can also be added.

When I started the saw, I really ate a big loss, because I always pulled hard and pushed it. It was completely sawing. I broke a saw blade and it was a problem to eat the next day. The right hand is like a crack, it’s terrible, but fortunately I finally learned how to cut it.

After the saw is finished, it has to be cut and cut. It is also a tired and bitter errand, but as long as you master the method, it is not difficult. First of all, it is necessary to hold the boring tool correctly. Keeping the straight motion of the boring tool when cutting the plane is the key to boring. The boring force has two kinds of level thrust and vertical pressure. When the file advances, the front hand pressure gradually decreases, and the hand pressure is large and then small. When the file is pushed to the middle position, the pressure of the two hands is the same. When the file is continuously pushed, the pressure of the front hand gradually decreases and the pressure increases. No pressure is applied when the file is returned. This way we are more difficult to cut.

Part 3: Locksmith Internship Report

Although everyone agreed that sawing round steel is a very long thing, but time is still running like a high-speed saw. In a blink of an eye, the one-week training of the fitter has left us. In addition to the nostalgia, the fine "taste" has indeed gained a lot of experience and insights. What is gratifying is that there is a friendship that helps each other.

Chairman Mao Zeng said: "Do it yourself, get enough food and clothing." This is indeed the case, even if the teachers are too good to be thorough, even if the sky is falling, it is better to let us fight the guns. Let us combine theoretical knowledge to understand, find problems and solve problems. I am afraid that such an effect is the purpose of education.

Take the saw steel, let's find that it is a little different from sawing wood. It doesn't do as much as sawing wood. I don't think how to saw it. But this can be different. It is necessary to estimate the saw according to a specific range, so as to reduce the error. After all, what you are doing is the parts. Everyone has learned physics. I have always heard the phrase "within the margin of error." It is indeed within the scope of the error. Otherwise, the sweat you have worked hard will be lost, unqualified, or even scrapped. When sawing, I feel that it is best to tilt a certain angle, but the angle should not be too large, about 10~20 degrees, so it is more convenient to saw, and it seems to save effort and saw fast. Although it is somewhat different from sawn wood, after all, things are similar, but there are similarities. When starting sawing, it should be slower, because you must first open a term called "slot". Generally speaking, it is to determine the movement of your saw blade back and forth. The trajectory, so that it does not cause a large error, can not be repaired later. Then saw it for a certain period of time, that is, open the slot, you can speed up, after all, to do well, still have to do fast, that is the best. But you can't just fly the saw quickly, so it's easy to produce high temperatures during the sawing process, so that the saw blade is "weak". It is also faster and more tired than people, it will soften and the saw blade will be flattened, even It is like the saw blade that I saw with my own eyes, "嘣嘣" screaming, it is best to gently hold the saw head with your left hand with light force, master the balance and direction, and the right hand twitches slightly with force. It also needs rest, so the saw will be pulled out for a while to make it breathable, take the cool, cool down. The approach I took at that time was, huh, huh, a saw in the left hand, a saw in the right hand, and a turn of the battle. The advantage of this is that you are not too tired because you can change hands. At the same time, the saw can also cool down. In this case, the school can also give the country resources, because the frequency of changing the saw blade is about one-third of that of others. I vaguely remember that for so many days, I did not break a saw blade. How good is it, echoing the national policy, isn’t it a “saving society”? Contribute to environmental protection and reduce a lot of "carbon emissions." When the semi-finished product is about to be sawn, it is necessary to slow down as much as sawing wood.

When using a sickle, when you are frustrating the object you want to polish, you should always maintain balance, otherwise it will be worn away, and I will grind it. The screaming of 123 is still the same. It seems that it has not changed much. I vaguely remember that when I first started, I was always grinding. The reason is because my posture is not standard enough. Explain first, the standard action is that the left hand palm and the part of the thumb are pressed against the front part of the file, the other 4 fingers are close together, and the right hand grips the handle, still frustrating back and forth. When you are frustrated, you should level your hands and master the balance. Remember that your left hand should not be pressed too hard. I, at the time, I always liked to push down my left hand unconsciously, so it’s not hard to imagine that although I was very hard at the time, I started to do it faster than I did, but I later lost a lot of time in this area. I was caught up in the head and was relatively backward. When grinding, be sure to endure loneliness, although it is very boring, but you must set yourself a goal: I have to smooth it here, and then again. . . Wait for positive psychological cues. This is indeed a kind of tempering and willingness to work. After grinding for a long time, I found that there is a "feel" like playing basketball. And the more you grind, the more you feel, this is a piece of art that belongs to me personally. I want to be more elaborate, to make it more perfect, and better than other students! Don't think that we are just doing the homework, In fact, it is also secretly competing.

This training not only gained the above experience, but also felt the warmth and unity of the collective. Once the classmates need help, especially the female classmates, I will not hesitate to help generously. After all, this is physical work, and the girls must be worse than the boys in physical strength.

So much valuable experience is indeed worth cherishing memories, but the fly in the ointment is that I feel that it is not a feeling, in fact, China's productivity is indeed not developed enough, and the cost of processing like this is too high. The industry of a country is closely related to the machinery manufacturing industry. If China wants to enhance its creativity, it must transform its production process, improve efficiency, reduce costs, and develop core technologies. Classmates, we are studying engineering, and we are engaged in technology. If we have the opportunity to continue our studies in the future, we have the responsibility to let China lead the world's commanding heights, let foreigners come to work for us, give us errands and let them whisper. Ask us to learn from the teacher. At the same time, there is also room for entrepreneurship.

Ok, how much will you recall tonight? I hope that I can exchange memories for you later.
