Maybe I was in a hurry at that time. I wanted to tell you all about cars, not only the history of automobile development, used cars, auto repair, automobile manufacturing and new energy. However, when registering the banner number, I forgot to consider every word. Here is an explanation. I will systematically introduce you to the knowledge about automobiles. In the next few days, I will mainly introduce the four major processes of automobile manufacturing (stamping, welding, painting and assembly). In the future, I will introduce other new energy sources such as automobiles.
People are fickle, and the noble head that was just lowered yesterday will be high today. I have decided that I must write what I want to write in the future, and I will not cater to the so-called hidden rules. Please forgive me for being bohemian and loving freedom all my life. As night fell and neon lights flashed, a person shuttled between the school and the Southeast Automobile Factory, looking at the heavy traffic outside the window, thinking that many people had seen cars, but not everyone knew how cars were made. After all, the relevant automobile major was also opened in the past ten years. Therefore, I think some people still like to talk about car manufacturing. The main reason is that it is impossible to talk about cars without mentioning car manufacturing. Yesterday's stamping was very simple to write. Yesterday's mistake came back today. I hope I can write a little better.
A car from scratch, the car contains numerous parts, large and small, how is it created?
Simply string together the four major car manufacturing processes to answer this question.
The automobile factory punches the steel coil into various sheet metal parts (such as five doors and one cover, fender, roof, etc.) that make up the car body through punching machines and other equipment and stamping dies in the stamping workshop. Then each sheet metal part is sent to the welding workshop for body assembly. The equipment used here is mainly welding torch, jig and robot. With the development of industrial technology, more and more manual spot welding operations will be replaced by robot; after the assembly, the car body is sent to the painting. Painting is the gathering place of the core technology of an automobile factory. Generally, the painting needs to be sprayed at least three times. The first layer is mainly ED layer for rust prevention, and the other two layers are mainly for beauty. After painting, go to the last assembly station. The assembly is mainly to assemble various parts of the car on the car body, such as engine gearbox suspension tires, etc. After the final assembly, a car is basically finished, but the car after the final assembly must go through some rigorous tests. Only the car that passes the test can be delivered to the customer.
