[1], Stamping parts reasonable selection of equipment, according to the actual manufacturing process of stamping pressure, mold structure and height and many other aspects of the analysis, the existing manufacturing facilities are combined, the application of facilities and mold design work is closely related. It is necessary to formulate the relevant design requirements according to the relevant design and determine the type of equipment. If the application of manufacturing equipment is small, stamping related calculation values are small, but when the specifications of the mold are large, the facilities that need to be selected are relatively large. Choose according to the actual specifications of the mold, and choose the equipment that meets the height and the size of the leakage hole. The design of the mold needs to pay attention to these aspects: first punch the pressure and the balance of the mold; secondly, calculate the data and calibrate the relevant power; finally, in the bending and other processes, for the quality of the parts, the manufacturing process needs to be calibrated, so that the manufacturing of automotive parts can proceed smoothly. The body, internal mechanism and compartment seats of a car are all produced by the stamping process of steel plates. The manufacturing process of automotive hardware stamping parts is the basic technical ability of automobile production, which then determines the cost performance and appearance of the car body. The more intuitive part of the car composition is the car body, which is also an important part of the car. The manufacturing process of the automobile is directly related to the service cycle of the automobile, and the stamping manufacturing process of the automobile parts is improved. The stamping process is an important competitiveness in the automobile industry. [2], the material selection requirements of the stamping parts die 1, the type of material selection of the stamping parts die, at present, the stamping parts die production materials can be roughly divided into: cemented carbide, rigid cemented carbide, zinc-based alloy, low melting point alloy, polymer material, aluminum bronze, etc., to achieve the development trend of various forms and types of stamping parts dies. Generally speaking, the manufacturing process of the stamping parts die mainly goes through three aspects: the determination of the working conditions of the die, the determination of the steel grade, and the processing. In actual processing, in order to determine the rational application of stamping die production materials, it is explored from the multi-element level of stamping die production. 2. The material selection conditions of stamping die, combined with the material selection conditions of stamping die, the requirements are summarized as follows: (1) The determination of the applicable environment of the die. As an auxiliary model for the production of automobiles, mechanical parts, etc., the die is always accompanied by all aspects of actual production. In order to avoid the problem of temporary damage of the die in the actual use of the die, when making material selection, it is necessary to make a reasonable choice of die materials according to the actual application environment. If the die application environment is high temperature, the material of rigid cemented carbide and cemented carbide can be used as an option. If the die is used in a highly corrosive and oxidizing environment in the later stage, polymer materials, cemented carbide and other materials can be used as an option. (2) Precision conditions for die manufacturing. Stamping die, during the actual production period, should be comprehensively evaluated according to the actual situation of stamping product processing in the later stage. If the stamping die is mainly used for automobile stamping production in the later stage, the die production should be carried out with flexible cutting and good flexibility materials as product processing, including: zinc-based alloys, low melting point alloys, etc. This selection standard is mainly for the convenience of processing personnel. During the processing and production period, the stamping die can be manufactured and the local die precision treatment can be carried out.
