What is the complete process of producing a car? What kind of production equipment is needed?

The complete process of a car production includes four main production processes: 1, stamping 2, welding 3, painting 4, assembly

Stamping process: stamping is the first step of all the processes, the operation is actually relatively simple, first of all, the steel plate in the cutter to cut out the appropriate size, and then in a stamping machine for the initial cutting, this time generally only punch, edge cutting and so on, in order to the next operation, after a simple punch, edge cutting, will enter the real stamping and molding, the next operation, the next operation, the next operation, the next operation, the next operation, the next operation, the next operation, the next operation, the next operation, the next operation. The next operation, after a simple punching and cutting, will enter the real stamping and molding process.

Stamping forming is realized by the stamping machine and the mold, each workpiece has a mold, as long as a variety of molds mounted on the press bed can be stamped out a variety of workpieces, the role of the mold is very large, the quality of the mold directly determines the quality of the workpiece. Most of each process is first through the stamping molding, and then through the punching, cutting, flanging and other processes, and finally will become the required workpiece.

Welding process: the most widely used in automobile body manufacturing is spot welding. Two pieces of body parts welding, its edge every 50-100mm welding a point, so that the two parts to form a discontinuous multi-point connection. Welding the entire car body, usually need thousands of welding points.

The strength of the welded joints is very high, each welded joint can withstand 5kN tension, and even tear the steel plate, still can not be separated from the welded parts. There is also a large amount of riveting used to process the body.

Painting process: painting has two important roles for automobile manufacturing, the first is to prevent corrosion of the car, the second is to increase the beauty of the car. The painting process is more complicated and has higher technical requirements.

There are mainly the following processes: pre-paint pretreatment and primer, paint spraying process, drying process, etc., the whole process requires a large number of chemical reagents and fine control of process parameters, the paint materials and the requirements of the various processing equipment are very high, so the coating process is generally for the company's technical secrets.

Total assembly process: total assembly is the body, engine, transmission, instrument panel, lights, doors and other parts that constitute the whole car assembly to produce a complete car process. Modern car assembly operations, with the help of computers and robots. However, some processes are difficult to let the robot operation, such as instrument panels, interior parts installation, etc., the most labor-intensive place is the interior parts assembly.

There are four main modules in a general assembly workshop, namely, the front enclosure assembly module, instrument panel assembly module, lamp assembly module, chassis assembly module. After the assembly of the modules and the installation of parts and components and then after the wheel positioning, lamp field of view inspection and adjustment of the whole car can be off the line.
