In the field of autoparts product processing manufacturing, the precision of stamping parts is directly related to the overall performance and safety of the car. The synergy of advanced molds and stamping processes is the key to ensuring that accessories achieve micron-level precision.The design of advanced molds is the foundation. At the beginning of the design of high-precision molds, computer-aided design (CAD) and computer-aided engineering (CAE) technologies are fully utilized. Through CAD, the three-dimensional model of the mold is accurately constructed, and every detail, such as the size, shape and surface roughness of the mold cavity, is planned in detail to ensure a perfect match with the design requirements of automotive accessories. CAE technology simulates and analyzes the stamping process to predict the flow and deformation of materials in the mold and possible stress concentration points. For example, when designing the stamping mold of the automobile engine bracket, CAE simulation can find the parts in the mold structure that may cause uneven deformation of the material in advance, and then optimize the mold design to avoid affecting the accuracy of accessories due to mold design defects during actual stamping.In the mold manufacturing process, advanced processing technology and high-precision processing equipment are used. For example, ultra-precision CNC machining machines are used to perform milling, grinding and other processing operations on key parts of the mold to ensure that the dimensional tolerance of the mold cavity is controlled within a very small range, and the tolerance of some key dimensions can even reach ±5 microns. At the same time, special processing methods such as EDM and wire cutting are used to manufacture complex shapes and fine structures in the mold, such as small heat dissipation holes and precise threads, to further improve the manufacturing accuracy of the mold.In terms of stamping technology, parameters such as stamping pressure, speed and stroke are precisely controlled. Modern stamping equipment is equipped with high-precision sensors and intelligent control systems, which can monitor and adjust various parameters in the stamping process in real time. When stamping accessories such as automobile body covers that require extremely high surface flatness, the stamping pressure is precisely controlled to make the material fit the mold cavity evenly and avoid local deformation or wrinkles due to uneven pressure. The reasonable setting of the stamping speed is also crucial, which affects the deformation behavior of the material and the degree of wear of the mold. By optimizing the stamping speed curve, the friction and impact between the mold and the material can be reduced, the service life of the mold can be extended, and the stability of the accuracy of the accessories can be ensured while ensuring the quality of the accessory molding. In addition, the multi-step stamping process is used to decompose the complex parts forming process into multiple simple stamping steps, and strict dimensional inspection and adjustment are carried out between each process, which further improves the accuracy of the final parts.In summary, the close combination of advanced molds and stamping technology, and the all-round control from design, manufacturing to stamping process, enable autoparts product processing to achieve amazing micron-level precision, laying a solid foundation for the high-quality development of the automotive industry.
