The so-called automobile stamping technology refers to the adaptability of stamping parts to handicrafts, that is, whether the designed stamping parts meet the stamping process requirements in size, size accuracy and benchmark, structural shape, etc. Automobile stamping parts should have good handicrafts and economy. The important marks to weigh their level are the number of stamping processes, the number and size of the car body assembly blocks, the structure of stamping parts and other factors.

Reducing the process number of stamping process means reducing the number of stamping pieces, saving the number of tooling, simplifying the transmission device of stamping process, reducing the area of operators and stamping area, which is an excellent measure to save investment and energy consumption. Therefore, stamping manufacturers can take stamping process number design as an important way to reduce the cost of automobile manufacturing, and even improve the product design to meet the system Requirements for manufacturing process.

At the same time, a reasonable overall body block of the largest size should be accepted, such as a whole body side panel and roof cover plate, which can not only make the appearance of the car beautiful. The air resistance is reduced, the number of stamping parts and solder joints are reduced, and the cost is effectively reduced. In modern automobile manufacturing, a large number of high-strength steel plates and galvanized steel plates with coiled materials and thin shell integral body structure are required to use the new stamping technology.

In automobile manufacturing, 60% - 70% of metal parts need to be formed by plastic processing. Stamping is an important means to complete metal plastic forming. It is one of the basic, traditional and important metal processing methods. For example, all kinds of body covering parts, interior support parts, structural reinforcement parts, as well as a large number of auto parts, such as exhaust elbow and muffler of engine, hollow camshaft, oil pan, engine support, frame structure parts, cross beam, etc., are all developing towards the production direction of precision, multi-function, high efficiency, energy saving, safety and cleaning through stamping forming technology The level and quality of manufacturing technology have a direct impact on the quality and cost of automobile manufacturing to a large extent.

The outstanding advantage of modular stamping is that it can combine the flexibility of stamping system with high efficiency production. Flexibility has a wide meaning, such as the various requirements of the geometry of automotive stamping parts, which can be obtained only through free programming, reflecting the flexibility of machining shape. For example, it is not only suitable for the production of large-scale single variety stamping parts, but also flexible for the processing of small batch and multi variety.
