Model essay on fitter training report
Time flies, and two weeks of locksmith training is over in a blink of an eye. Although I was very tired and bitter during the training, I got a lot of blisters on my hands and put on a lot of band-AIDS, but I felt very fulfilled! Because we have learned the necessary knowledge as fitters and also exercised our hands-on ability. But it also made me more deeply understand the true meaning of grinding the iron pestle into a needle as long as the kung fu is deep! At the beginning of the first day of training, the teacher told us that the fitter was very bitter and tired, but this was the foundation. Because I once organized a trainee in high school and came into contact with locksmith. I was making a hammer at that time, so the impression of locksmith was quite interesting. But after two weeks of professional training, I know that former students are really superficial. The locksmith seems simple, but it is actually a technical job that tests our patience and perseverance! At first, the teacher briefly introduced the basic knowledge of locksmith and the tools to be used. Of course, the most important thing is to pay attention to safety. Incorrect operation methods are likely to lead to safety problems. After the teacher has introduced us, we will go to the field to operate.
The task of the first day is to draw a line on the plane. The purpose of drawing lines is to define the machining boundary. For us, drawing lines on the iron plate for the first time encountered many problems. The teacher also knows that it is difficult for us to draw a good floor plan. Before making the plane mark, the teacher told us a lot, and at the same time, the teacher gave us a lot of guidance in the process of making the plane mark. Therefore, under the guidance of the teacher and the mutual help of the students, the students easily completed the first plane marking of the fitter.
The next day's training content is planing and cutting. Before the chisel officially started, the teacher told us the basic knowledge of chisel. The operator's standing position and posture should be convenient for exerting force, with his body center of gravity leaning towards his right leg, slightly leaning forward, his left foot crossing the first half, his knees slightly bent, keeping natural, and his right foot standing straight. The hammer master grasps the hammer handle with five fingers of his right hand, closes his thumb on his forefinger, and points his jaws in the direction of the hammer head. In the process of swinging the hammer, the five fingers are always clenched; Loose grip method, always hold the hammer handle with only thumb and forefinger. The teacher said that at first, because of inexperience, he would knock on his hands. After listening to it, we felt very tired. At first I took a piece of iron and the teacher helped me chisel it. I continued to chisel. I've been chiseling for a long time, less than half, but there are several bubbles in my hand and my fingers have been hit several times by a hammer.
When I couldn't even lift my hands after a day's work, I knew that the locksmith was not as simple as I thought! I decided to work harder! From grade three to grade five, our training content is filing. This object was a piece of iron covered with rust yesterday. First saw off one side, and then file the surface flat with a file. Finally, if the line of 0.05 cannot be inserted into four corners, it will be successful. At first, I had no idea about 0.05 silk. Later, the teacher said that our hair is generally 0.08 silk, that is, the diameter is thinner than the hair, and it will not be inserted!
In order to achieve this effect, we fell for three days and our hands were blistered. But this is an exercise for us! This is very exercise our will! So I told myself to persist! After a week of training, I have a basic understanding of locksmiths. Make full preparations for next week!
In the second week of fitter training, first drill holes with different diameters. After drilling, we screw holes and threads. After that, I continued to file. Although I feel bored and tired, it is really not easy to file the final result! Looking at our hands like coal, everyone's face is black, all in order to achieve the final goal-there are less than five lines on both sides, and the angle is vertical! This is the final exam! Although I think it's almost enough, the verticality meets the requirements every time, the parallelism is not enough, or the parallelism meets the requirements. Finally, I can only regret handing in my homework. ...

The two-week locksmith training is over. Although we are very tired in training, we are very happy because we have learned a lot of useful things and exercised our practical ability. Although the training period is only two weeks, it is only a small part of our three-year college life, but it is a very important part. It's hard for us to forget. After all, it is a real experience of society and life. To carry out locksmith training, safety issues must be put in the first place. Through the master's explanation, we learned about the dangerous operation actions that students are easy to make in training. For example, fooling around in the workshop, operating the machine tool without the permission of the master, incorrect operation method and posture, and so on. An unintentional action or a small negligence may lead to mechanical accidents or even personal safety accidents.
Through this locksmith training, I learned the basic knowledge and operation methods of metalworking. Mainly learned the following knowledge: the basic types of metal processing are fitter, lathe worker, casting welder and so on.
In the training of locksmiths, we know that the main contents of locksmiths are scraping, drilling, tapping, sawing, filing, assembling and marking; Understand the structure, classification, selection, filing posture, filing method and quality inspection of archives. First of all, we must get the right gear. It is the key to keep the file moving in a straight line when filing the plane. There are two kinds of filing force: horizontal thrust and vertical pressure. When pushing the file forward, the front hand pressure gradually decreases, and then it decreases when pushing the file to the middle position, and the pressure on both hands is the same. When pushing the file forward, the front hand pressure gradually decreases and then increases. No pressure is applied when the file is returned. This will make it easier for us to file. At the same time, I also know that the locksmith's safety technology is:
1, the clamping table should be placed in a place convenient for work and suitable for light; Drilling rigs and grinding wheels should generally be placed on the edge of the site to ensure safety.
2, the use of machine tools, tools (such as drilling machine, grinding wheel, hand drill, etc. ), should be regularly checked, found damaged shall not be used, need to repair the rear can use.
3. When clamping tools in a vise, it is forbidden to use a hammer to beat the handle or steel pipe of the vise to exert clamping force.
Then scrape, grind, drill, hinge, tap and so on. Although it is not very standard, it is the crystallization of our sweat and the result of our two-day struggle.
To tell the truth, locksmith training is boring. He may have been doing an action repeatedly all morning, but he should be strong and do it just right. That is, a file that goes back and forth on the workpiece with a file. By noon, the whole person's hands were sore and his legs were stiff. However, when he is tired, he can see the teacher personally guiding and demonstrating. He is also sweating and panting. A few days later, looking at my own processing results, I want to say thank you to the teacher who guided us.

Every semester I look forward to the arrival of training, because I can finally get rid of what is basically pure theory, to know, understand, contact and master practical things, and to feel some real things. Although the fitter training and lathe training at the end of this semester have little to do with our major, this training is particularly worthwhile, not only expanding our knowledge, but also knowing and mastering a lot of new things. Let me talk about our training. The first week of training is fitter training, training in the afternoon, going to noon and coming back at night. It just snowed, the road was slippery, and I rode my bike for nearly an hour. When we walked to the training center, to be honest, this place was too simple. What impressed me was the teacher's serious face and high requirements. It is very cold in the classroom. The teacher didn't rest all day, ate in a hurry and caught cold with us. The teacher is old and hard. The first is safety, which should be strictly in accordance with the requirements of operating procedures and safety first. At the end of our training, we need a 2.5*2.5*2.5cm cubic iron block. After the teacher taught us tools, usage and basic operation, we mainly did it ourselves. Worktable, hacksaw, large, medium and small jigs, brushes, straight steel rulers, vernier calipers and other necessary tools were selected in one afternoon and started to be processed, but they were not finished yet, and the parts were roughed again the next afternoon. However, on the third day, when it was polished, it was smaller than the required size and failed to meet the standard, so we had to start again. Fortunately, it was completed and handed in before the deadline. When you are tired during processing, take a rest and look at the relevant books on the teacher's podium. I didn't read intensively, but I learned a lot. In the process of dealing with it, students exchange and discuss with each other, which not only enhances the friendship between students, but also learns new knowledge, killing two birds with one stone.
Machining iron blocks with hacksaw is a helpless but repetitive process. Only one piece of material needs to saw off at least six faces. Sometimes my hands are sore from twelve to five or six. But every time I finish it, I feel a little fulfilled, and I am one step closer to success.
Although this training is not the hard work I have done, I believe it has also honed my will, and let me enjoy the process and realize the success and joy. Polished surfaces are more unbearable than saws, because it requires not only saws, but also all large, medium and small saws! The straightedge finds the plane, and the processing requirements are very fine. Every time I grind, I feel the same joy in my heart.
During training, my hands are covered with oil, and sometimes I get it on my clothes. Iron filings and dust are flying all over the sky, and my clothes are the same color as oil stains. There are iron filings in the nostrils, and the working conditions are hard and boring, but there is really happiness inside. This training has made me realize the waiting and patience, honed my will, and learned that if I want to succeed, I must step by step, be down-to-earth, not afraid of failure, and strive for perfection. In short, this training has benefited a lot. Finally, I have some regrets. I wanted to take my week's work away as a souvenir, but I didn't send it after I handed it in. What a pity.
The second week is lathe training. This time our class will go in the morning instead. After arriving, we haven't met the teacher in our workshop county. The first feeling is particularly cordial, because either the teacher wearing a suit and tie keeps people away from him, or he thinks the distance between the teacher and the students is very cordial and close. Like the last teacher, he first emphasized the safety problem and told us the problems that should be paid attention to when operating, such as wearing work clothes, working hats and gloves. Then he talked about the operation of c620- 1 car factory. There are six lubrication methods for machine tools: 1 and oil throwing. 2. Pour the oil. 3. The oil rope guides the oil. 4, oil pump oil. 5. Dali Petroleum Cup. 6. Butter cup, 23 oil filling points. The machine tool consists of seven parts: spindle box, change gear box, feed box, tray box, lathe bed, tailstock and accessories. Tray boxes are divided into large trays, medium trays and small trays. These three trays are used together to control the feed quantity, direction and size. The whole machine tool has 25 operating handles: one controls speed, one controls feed direction, one controls feed quantity, one controls turning tool and one controls switch. The use of 25 operating handles constitutes the operation process used in machine tool processing. In addition, when machining workpieces, lathes are divided into automatic and manual. When talking about turning tools, the teacher told us the shapes and names of all turning tools. Turning tools are divided into three types according to materials: K-type cemented carbide (nickel cobalt), P-type cemented carbide (nickel titanium cobalt) and M-type cemented carbide; There are two kinds of turning tools: 45-degree turning tools and 90-degree turning tools. Turning tool consists of tool body (common steel) and tool head (special alloy). The shapes that the turning tool can turn are: oblique fracture, arc, triangular thread and trapezoidal thread.
Finally, the teacher listed the specific meaning of machine tool model, such as C620-1/representing the greatly improved design code, 20 as the main parameter, 6 as the grouping code, C as the machine tool category code, cm6 12525 as the main parameter,1as the model code, and M as the characteristic code, C and 6. There are c6 140a, x6 132, b6065, b20 12a, b5020, etc. What impressed me was that: The teacher could have taught us only the part to be done in this training, but he didn't slack off. He not only talked about what we wanted to learn, but also talked a lot about lathes. He spoke very seriously on the blackboard. He personally demonstrated and introduced each component on the machine tool. Because there are too many people, it is impossible to read it all at once. He repeated it and finally gave individual guidance. In a word, I saw the teacher's heart to let us learn more knowledge. In order to let students learn more things, he worked tirelessly, which moved me very much. Finally, we not only completed the turning of parts that meet the teaching requirements, but also fully understood the use and operation methods of every part, every oil hole and every handle of the lathe. We digested and absorbed what the teacher said. Teacher, you have worked hard! ! ! This training is very worthwhile. He taught me a lot, learned knowledge, honed my will, and personally experienced the learning method. Promote the relationship with classmates; The teacher moved me very much. I look forward to the training next semester.
