Although our internship in this company is very short, we have learned a lot of knowledge we want to learn in this company, which gives us a better understanding of the construction machinery industry. I know that I learned very little at school, and there are many things we don't know. During the internship, we and the masters studied the knowledge of construction machinery seriously, actively started work, cultivated their hard-working spirit and carefully understood the structure of the locomotive. Completed the purpose of disassembly and assembly of construction machinery and met the requirements of our internship. We have learned a lot about corporate culture and corporate management system. We not only made a breakthrough in our major, but also learned a lot of knowledge about business management. This internship has played a very important role in my future work.
The practice of construction machinery is not only a more intuitive understanding of textbook knowledge, but also a spirit of mechanical inheritance. Internship is an opportunity to apply theory to practice. Usually this kind of opportunity is rare, and it is not that simple to arrange an internship. Therefore, such an opportunity is very precious. There is no end to science. As a new generation of national builders, we have the obligation to take the torch from our predecessors and go forward bravely. There is a long way to go in Xiu Yuan, and I will go up and down. A generation of students should be brave enough to take responsibility. In drilling machinery, we should be brave enough to face challenges. Although construction machinery originated in China, it lags behind Europe and America in this respect. But we firmly believe that the revival of construction machinery in China is only a matter of time. This will be a great responsibility for the people of Sri Lanka. As long as all of us continue to work hard and study hard, we can finally carry forward the construction machinery in China.

Under the leadership of the company's staff and teachers, we visited mechanical equipment such as shield machine, vertical rolling mill, reducer and giant devices such as giant gears and power mechanism.
Shield machine: Shield machine, also known as "tunnel boring machine", integrates mechanical, electrical, hydraulic, remote control, measurement, detection, sensing and information technology, and can form tunnel excavation, slag discharge and lining at one time, which is widely used in underground and tunnel construction such as transportation, hydropower, energy, subway, highway and hydropower. Shield tunnel construction has the characteristics of high automation, labor saving, fast construction speed, one-time hole formation, no influence from climate, controllable ground settlement during excavation, little influence on ground buildings, and no influence on water traffic during underwater excavation. Shield machine construction is more economical and reasonable in the case of long tunnel line and large buried depth.
This project produces a series of tunneling equipment products with shield machine as the leading product in advance, which serves the needs of infrastructure construction such as subway and expressway in our province and replaces the current imported products.
Retarder: Retarder is a kind of power transmission mechanism, which uses the speed converter of gear to slow down the number of revolutions of the motor to the required number and obtain greater torque. Among the mechanisms used to transmit power and motion, the reducer has a wide range of applications. It can be found in almost all kinds of mechanical transmission systems.
Its application can be seen from high power transmission to low load and precise angle transmission. In industrial application, the reducer has the function of slowing down and increasing torque.
Mega-devices: design principles, structural characteristics, static performance and seismic performance of mega-frame structures, mega-frame-core tube structures and mega-frame-braced structures, and the influence of design parameters on structural performance. Mega-structure is a new type of super-high-rise building system developed in recent years, which has broad application prospects.
Ganda Heavy Industry has more than 300 sets of large and medium-sized production equipment, including more than 40 sets of precision large-scale equipment such as CNC machining center, boring and milling machine, gear hobbing machine and gear grinding machine, which can process workpieces 100 tons.
V. Internship experience
Through this internship opportunity, I understand that only through practice and accumulation of experience can we lay a solid foundation for future related work. Because no matter any theory or knowledge, it can only play a role if it is combined with practice.
As college students in the new era, we must not rely solely on books, but also test and exercise in practice. I am very happy to have the opportunity to practice in some companies and get close to professional things. Internship is an internship for undergraduate students to complete basic courses and professional basic courses, which makes us have certain expectations for our professional direction. There is still a big gap between actual production and what we have learned in textbooks. Theory and practice are not exactly the same, so we can't copy the knowledge from books into production, which will not only fail to achieve the theoretical effect sometimes, but also cause great economic losses and waste of resources sometimes. Book knowledge is systematic and idealized, but due to the influence of factory funds, policies and regulations, staffing and other factors, it is difficult to thoroughly implement professional theoretical knowledge in actual production. But once used, it will have a good benefit effect.
Combine theory with practice through practice, including physical survey of various equipment, equipment operation steps and matters needing attention. And the actual process of each process. These Otawa books are the same. Through the observation of mechanical equipment, it makes up for the deficiency of theory and deepens the memory of knowledge. Soon we will step into the social classroom, facing the problem of choosing a job and getting employment. In this way, we need to have a deeper understanding of the profession and master all the knowledge needed in the profession. In this way, in our future work, we can easily deal with problems without being overwhelmed by difficulties. Opportunities are only for those who are prepared. Only by constantly enriching one's mind can one face challenges with more confidence and become a strong person in life and career.
Although it was only half an hour, I saw a lot, heard a lot, and learned a lot, which also verified the famous saying that "it is better to read Wan Li Road than to read thousands of books". In the days to come, I will study harder, do more work, think more and observe more, so as to make my professional knowledge more skilled and lay a foundation for my future work.

During the one-week internship in the machinery factory organized by the school, I learned a lot, which made me more deeply aware of the importance of practice. Through this internship, I have a lot of reflection. Only theoretical knowledge is not enough, but also basic practical ability, which is exactly what I lack. Through practice, we have a better understanding of the profound truth contained in the sentence "apply what you have learned".
Our main practical activity is to visit _ _ Machinery Factory and Qiu Jin Hongri Machinery Factory to learn about the industrial production business of the factory, the working process and principle of machine tools for manufacturing large, medium and small parts, and the process of producing and processing various parts. During the internship, I listened carefully to the arrangement of the instructor, visited the students in groups, listened carefully to the explanations of the factory masters and teachers, learned the safety rules and regulations of the workshop, learned the working principles and operating specifications of various large and medium-sized machines and the technological processes of various products explained by the masters, and compared them with the theoretical knowledge I learned, which benefited a lot.
Through this internship, we learned about the production mode and technological process of modern machinery manufacturing industry. Familiar with the main molding methods and processing methods of engineering materials, the working principle and typical structure of the main equipment used, the use of fixtures and measuring tools and the safe operation technology. Understand the knowledge of mechanical manufacturing process and the application of new technology, new technology and new equipment in mechanical manufacturing. Have preliminary independent operation skills in the main molding and processing methods of engineering materials. In the process of understanding, being familiar with and mastering certain engineering basic knowledge and operation skills, we have cultivated, improved and strengthened our engineering practice ability, innovation consciousness and innovation ability.
Through this internship, let us understand that we should be careful and not careless. At the same time, it also cultivated our awareness of observing labor discipline, observing safety technical regulations and caring for state property, and improved our overall comprehensive quality. Soon we will step into the society and face employment. The employment unit will not tell us the work to be done in detail like the teacher, but we need to observe and learn by ourselves.
Proceedings of 2022 Mechanical Practice Experience and Perception Model 4
The biggest labor intensity in metalworking practice is casting. In actual operation, every link of repeated sand filling → vibrating sand compaction → auxiliary compaction → demoulding can't be sloppy, otherwise the sand mold is indispensable, and we must be meticulous if we want to keep improving. But I think casting is really like what we did? Too much power.
So I looked up a lot of information and found that there are many advanced casting methods in industry, such as gravity sand casting, gravity inclined casting, metal mold casting, investment casting, vacuum casting, centrifugal casting, semi-solid metal manufacturing, electroslag casting, and some advanced casting X software, such as anycasting. It is a new generation of advanced casting simulation software system based on windowsx independently developed by anycasting Company of Korea. X system is specially developed for various casting processes, which can simulate and analyze the filling, heat conduction and solidification process of castings. With this in mind, I hope that the study during the internship can provide us with some useful X, which is convenient for us to study and help us to get in touch with advanced manufacturing knowledge.
Of course, there are also many types of work that I have learned a lot. For example, when I first came into contact with CNC machine tools, I had many advantages over ordinary machine tools:
1, high machining accuracy and stable machining quality;
2, multi-coordinate linkage can be carried out to process parts with complex shapes;
3. When the processing parts change, it is generally only necessary to change the program, which can save the production preparation time;
4. The machine tool itself has high precision and rigidity, and can choose favorable processing dosage and high productivity (generally 3-5 times that of ordinary machine tools);
5, the machine tool has a high degree of automation, which can reduce the labor intensity;
6. The quality requirements for X workers are higher, and the technical requirements for maintenance personnel are higher.
But unfortunately, we spend too little time on CNC machine tools and know too little about CNC machine tools.
Looking back on the whole internship process, there are gains and gains. In the final analysis, it is my own lack of basic knowledge, I don't understand the principle in practice, I have made many jokes, and even caused myself danger. At the same time, through practice, sometimes I have a strong interest in theoretical knowledge. In the future study of mechanical X, I will go to the library to consult my unclear basic knowledge and principles, learn more about X software, ask experts for experience, and learn more from my classmates and colleagues, so as to learn something to improve my mechanical design skills.

During the internship of _ _ weeks, I learned that design is definitely not a simple matter. It requires not only a rigorous and meticulous learning style, but also a serious and responsible learning attitude.
First, let's draw a sketch. According to the technical requirements, we use wildcards, straightedge and other measuring tools to measure the relevant dimensions of parts (such as the height, depth and length of parts and the diameter of circles, etc.). Finally, according to the standard, we all bought A 1 grid paper to draw pictures.
Next, I chose two important parts, the pump seat and the driving gear shaft, for surveying and mapping. Although I encountered some difficulties, I solved the problem quickly by discussing with my classmates and asking them for help. The most difficult thing is the mapping of assembly drawing. Although we have learned and have a lot of drawing experience, it is obviously not enough to rely solely on the knowledge in books. At this time, those who are superficial and half-baked to us don't know where to start at first, and they have no clue after thinking for a long time. We didn't have a clue until we looked up the book. We didn't know what to mark the geometric tolerance and how to mark it. Finally, we went there.
This course design enables us to master the methods and steps of parts mapping, understand the significance of hand-drawn sketches, master the use of common tools, and accurately draw parts drawings and assembly drawings according to measurement data and related standards, which further cultivates our serious and responsible work style, scientific and rigorous work attitude and teamwork spirit.
Finally, thank the teacher for accompanying us all the way through this _ _ day. Although it is hard, there are joys and sorrows. I believe this day will be the most unforgettable special time in my college life.
