Part 1: Metalworking Internship Report Fan Wen

I. Internship purpose

Metalworking technology is the basic production knowledge that is indispensable for people engaged in the production of various materials. Through independent practice, you can get in touch with the actual knowledge of production, master the basic knowledge and basic operation skills of fitters and turners, learn to use the fitter tools and ordinary lathes, understand the machining process of mechanical parts, and learn the basic process knowledge and basic process methods of mechanical manufacturing. Combine with basic process practice to train engineering practice and comprehensive ability to improve its comprehensive quality and thought level.

Second, the principle of practice

A fitter refers to a processing method for processing, making, and repairing raw materials, metal workpieces, mechanical equipment, etc. according to technical requirements using a fitter tool or equipment, such as a file, a scraper, a hand drill, a reamer, a bench vise, a small drill press, and an electric grinder. The machine is the main tool. It is generally hand-made, has the characteristics of simple equipment, convenient operation and wide application, but it has low production efficiency and high labor intensity, and is suitable for single-piece small batch production or assembly and maintenance operations. The basic operating skills of the fitter are scribing, boring, sawing, boring, drilling, reaming, boring, reaming, tapping, threading, correction and bending, riveting, scraping, grinding, machine assembly and commissioning, Equipment maintenance, measurement and simple heat treatment.

Third, the operation steps

Hammer processing

1. Observe and familiar with product design drawings, prepare raw materials and fitter tools;

2, draw a rectangle: According to the principle of the first small one, draw a rectangle of 23mm in length and 19mm in width on the bottom surface of the cylinder according to the size required by the design drawings;

3, the initial model of sawing: using a hacksaw to cut a rectangular parallelepiped with a cylinder on the bottom of the cylinder;

4. Rough grinding: After sawing the initial model, use a trowel to smooth the surface of the model for the next step;

5, draw the hammer outline: draw the hammer outline on the two sides of the rectangular parallelepiped 700*22 according to the principle of the freshman small one, and draw the corresponding line on one side of 22*18;

6, sawing the real sample model: using a hacksaw to draw the hammer outline drawn on the rectangular parallelepiped to cut out the same hammer shape as the design;

7. Precise grinding: After sawing the real sample model, the surface of the model is smoothed with a file and the size required by the design is achieved;

8. Drilling: Draw the position of the hammer handle hole, and use the drilling machine to drill the hammer handle hole;

9. Tapping the thread: slowly unscrew the thread with a swirling tool;

10. Grinding and cornering: Use a file to grind all the edges of the hammer to a 45-degree bevel.

Hammer handle processing

Use the ordinary lathe to be machined according to the design requirements under the careful guidance of the teacher, and use the spinner tool to unscrew the thread.

Assembly: Screw the hammer shank into the shank hole on the hammer head, and the entire process ends.

Fourth, internship experience

The entire processing of the metalworking internship actually took two days, but these two days brought us a lot of feelings and experience, we suffered a bitterness, but enjoyed the happiness; there was a setback, but we finally got the joy of success, so we Thank you very much for your guidance. From the metalworking internship, we have mastered the basic knowledge and basic operation skills of the fitter and the lathe, as well as the processing technology and operation method of the ordinary lathe, learned the mechanical manufacturing and parts processing process, exercised and improved our practical ability, so that We better combine theory with practice and consolidate what we have learned. At the same time, during the internship, we carried forward the spirit of solidarity and mutual assistance. The male students helped female students and students with strong hands-on ability to help students with weak hands-on skills. They helped each other to learn from each other, and learned how to cooperate and enhance the friendship between the students.

Part 2: Metalworking Internship Report Fan Wen

We conducted a 9-day metalworking internship at the school's school. During the period, we were exposed to three types of work: car, clamp, milling. Every day, everyone has to learn a new skill. Within three days, the process of making a finished product from the ignorance of each type of work. Under the patience and meticulous teaching of the masters and our positive cooperation, we did not have an injury accident, basically met the expected internship requirements, and successfully completed the metalworking internship.

"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 exercises, improves engineering practice, and cultivates engineering. Prime. This is a good opportunity for us to learn and exercise! I know a lot through this short and substantial internship.

In a blink of an eye, the two-week metalworking internship has ended. I have been sweating for two weeks, have had a failure, have had a pain, and have had a smile. It was in this sweat, failure, hurt and smile that I learned a lot of useful knowledge. I also deeply experienced the hard work and greatness of the workers, although the training period was only two weeks, at our university. It is only a small part of life, but it is a very important part. For us, it is very difficult to forget. After all, it is a real experience of society and experience life. The metalworking internship report is provided by the boutique learning network!

From the safety education, the use of action essentials and tools to the practical operation of picking up tools such as sickles, this is undoubtedly a process of combining theory with practice. Some things are to be explored by themselves, and some things are to be found in theory for practical use. From the beginning of the polishing plane, I learned that it is not so simple to do a good job, to verify it with reality. Seeing is not necessarily true, which reminds me of why the school wants us to come here for an internship. It is because we know how valuable it is to learn, and to learn and polish the plane, we must have a meticulous spirit to do our best, and let us realize The importance of hands-on. It’s just not enough to learn the theory. It’s not enough. Without practical experience, you can’t find your own hands-on ability. This requires a combination of theory and practice. More cooperation between the mind and the hands is needed. fitter

In the fitter training, I learned that the fitter's content is for scribing, boring, boring, grinding, drilling, reaming, reaming, tapping, and so on. Understand the construction of the file; classification, selection, boring posture, boring method and quality inspection.

In the boring, the teacher focused on the boring posture, the boring method and the quality inspection. 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. The teacher vividly showed us how to use the sickle and how to use the saw, and then after the specified position, began our task - to complete a small hammer.

In making this workpiece, we first saw a steel bar saw into a size close to the workpiece using a hand saw. When cutting about 23mm, hold the handle firmly with your right hand and hold the front end of the hand saw with your left hand. When sawing, the saw angle is about fifteen degrees. When cutting, you should apply force with your right hand. If you use your left hand to support the saw blade, you must put the saw blade in the right direction or you will saw it. The cutting speed should not be too fast. About 20-40 times per minute. After cutting off the gas cutting surface, we have left. About 19mm.

In the next work, we need to cut the surface of the cuboid into a plane according to the size of the teacher. The process of pingping is simple but it is not so simple. For example, when using a trowel to rub the surface, it is very boring. It may be that the work is repeated mechanically for a long time. At the beginning, we need to polish it with a big hoe, then it is Lieutenant, in the end, use Xiaoyan to make it flat. I have been repeating the process of smashing, and finally I have polished this rough iron rod.

The next task is to saw the next rectangular iron bar into the shape of a hammer. According to the figure, it is sawn into a triangular iron block, so that the basic shape of the hammer is completed, and after further boring and grinding, the hole can be punched.

Before punching, first scribe the hole to determine the center of the hole. First, use the hammer to make a large center eye at the center of the hole. Drill a shallow hole first to determine whether it is centered. When the hole is about to be drilled, the amount of feed is reduced to avoid jitter when the bit is drilled. When the thread is set, first press the center of the die with the palm of your hand and slowly rotate. During the rotation, it is necessary to rewind a quarter of a turn every revolution to break the chips, remove the chips, and add oil lubrication.

Although a workpiece is not finished, it is not a special standard, but it is actually exchanged with our sweat. It is filled with our intentions and expectations, and it is hard to say that the first piece of labor is full of joy.

In the next two days, we learned the mechanics. The mechanics were not finished by CNC, which required higher 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 the function of each handle to us, and then let us machine two main wheels and two large wheels. 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 need to make the diameter of the given cylinder from 28MM to 26MM, then use the two-wheeled knurling knife to emboss the surface of the cylinder. Switch to the cleavage knife to cut the cylinder.

Immediately, each group received a burr cylindrical rod, which is the material we are going to process. When tightening, it should not be too long, usually one-third of the workpiece and clamped in the spindle hole. Then adjust the speed, open the switch, move the tool holder to the appropriate position, open the opening and closing nut, and move the spindle to reverse the handle to start the car handle. The outer circle of the first handle, then the arc of the handle, and finally the surface of the handle is leveled with sandpaper. After the flattening, the handlebar is broken, and a handle is basically formed.

After half a day of practice, a finished product finally came out, which made us more confident. We started to take turns, and after six of our concerted efforts, we finally got six handles.

As a college student, we have experienced more than ten years of theoretical study. We have been told more than once that there is a gap between theoretical knowledge and practice. However, we have not taken this sentence seriously and have no chance to verify the actual gap between this sentence. how many. The metalworking internship gave us an opportunity to actually master the knowledge, leaving the rigorous environment of the classroom, we felt the atmosphere in the workshop. The eager eyes of the students and the conscientious and patient operation of the instructors constitute the common scenery in the workshop. We have felt the importance of hands-on ability in the classroom for a long time. We can't complete the actual work only by thinking and figuring in the brain. Only when we have a scientific knowledge system, we are proficient in practical ability, including mechanical operation and experience. Continuous accumulation can make knowledge flexible and effective in practical work. China's current education system makes it difficult for college students to enter the university through the joint entrance examination. Therefore, universities in the transitional stages of school and society have taken on the task of cultivating students' practical ability.

Metalworking internship is an effective way to cultivate students' practical ability. Based on this, students must give enough attention to this course, make full use of this month's time, and improve their hands-on ability. Here is another learning class. Through our hands, we supplement and question the theoretical knowledge we have mastered. This is the opposite of traditional classroom education. These two learning methods complement each other and complement each other, can fill in the gaps and make up for some blind spots. Through the metalworking internship, the overall feeling of actual production methods is still relatively backward. The advanced equipment introduced in the book is still not practical. The equipment in the internship is often characterized by high labor intensity and low technological content, but there are still some basic knowledge. Can be applied in practice.

During the internship, learn about turning, milling, and fitter. We have made our own handicrafts, milling and lathe internships. Everyone can learn the most fundamental knowledge of milling machines according to the teacher's requirements. The hardest is the number of lathes and fitters. The mechanics are the most dangerous. The students must first master the essentials of driving the lathe. 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 the steps of punching and tapping. A beautiful nut. A few days later, although many students had blisters on their hands and were sore, but they saw the finished products they made in the factory for the first time in their lives. Everyone couldn't help but feel a sense of accomplishment. I have summarized two parts, the internship part and the impression part of my internship.

Internship:

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, improve, and strengthen our engineering practice, innovation, and innovation capabilities in understanding, familiarizing, and mastering certain engineering fundamentals and operational skills.

4. Cultivate and exercise labor perspectives, quality and economic concepts, strengthen adherence to labor discipline, observe safety technology rules and protect the state's property, and improve our overall comprehensive quality.

5. Throughout the internship process, our discipline requirements are very strict, and the student internship rules have been formulated. At the same time, we have strengthened the requirements for completing the internship report, cleaning the machine tool site, and complying with the safety procedures of each type of work. Cultivation has played a good role in promoting.

6. The factory master scores the workpieces we have made, so that we have a clear understanding of the points of our products, which has a certain effect on improving our quality awareness.

7. The mutual help between the students can complete the task, which gives us a deeper understanding of the concept of the team, and also makes us understand the importance of teamwork!

Part of the impression:

1. Metalworking internship is an effective way to develop students' practical ability. It is also a college student, engineering college student, a very important and particularly meaningful practical class. Metalworking internship is another opportunity for us to master the knowledge. We leave the rigorous environment of the classroom and we will feel the atmosphere of the workshop. At the same time, I feel more of the mood of a worker, which makes us more aware of the responsibility. Someone told me that we are not a mechanical student. It is useless to learn this. I participated in this internship with suspicion, but the final conclusion is that I denied it. It gave me more than just mechanical professional knowledge. It is a power, creativity and adaptability.

2. Labor not only transforms the natural world, but also transforms one's thoughts. After this week's metalworking internship, I also have a deep understanding of this.

1>, labor is the most glorious, only to practice can understand the bitterness and fun of labor.

2>, perseverance, patience and patience.

3>, be responsible and pay attention to safety.

4>, as long as you pay, you will gain.

3. Internship brings us more than just experience. It also cultivates our hard-working spirit and rigorous and serious style. We have learned a lot of things that we can't learn in the book. It allows us to understand life, to explore life, and to provide an opportunity for us to understand and understand life in many ways. It is a kind of driving force for life, promoting the development of our knowledge, feelings, intentions, and formation, and helping ourselves to improve ourselves. At this time, I still miss the metalworking internship with a sense of accomplishment. It enriches our knowledge and makes us more aware of the phrase: "There is a glimpse of the end of the paper. I know that this must be done." Practice is the truth. Inspection standards, through 10 days of metalworking internship, I learned a lot of work common sense, I also got the will to exercise, there is bitterness and happiness, this is another valuable wealth in my university life, for my future study and work will have Great impact.

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 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. 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. The 10-day metalworking internship 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 needs us all after the internship. According to my own situation, I feel, rethink, be self-satisfied, and gain something. Therefore, the internship report and the task of the diary give us this opportunity, and the final innovative design also tests our innovative ability and new. improve!

Concluding remarks: Eyes are seemingly simple things that can be deceiving. They are not necessarily good. Only by knowing them in person can they make the ideal product. Practice is the truth of learning! If there is another chance, I will participate. Such internships will also use practice to improve their knowledge and their abilities, in order to have a higher ability to adapt to society when they leave the campus. I am grateful to the school and the teacher for giving us the opportunity to hone ourselves and improve ourselves. The goldwork internship is bitter and enjoyable. "The days will be reduced to the people of the S., and the people will suffer first, and they will be hard-working, hungry and refreshed. Also!" This ancient saying is used to describe our metalworking internship is no better! After the tempering of the mechanics, fitters and other types of work, we have finally completed this exciting 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 They will not engage in these tasks in the future, and there is no possibility of touching them. However, the experience and feelings brought by the metalworking internships are a valuable asset to each of us. . 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 worthy of 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 internship of the metalworking, I want to have another one.
