In this process, the following aspects should be paid attention to when using sample drawings, the expansion method should be convenient for saving materials and processing timeliness; the position and direction of riveting, sprouting, punching bumps (bags), etc. should be marked in the section view, to facilitate Processing can also be understood more intuitively; parameters such as plate thickness, material, and plate thickness tolerance should be checked, and the points that are prone to errors should be marked to remind; for places with many sizes and more complex, this part of the map should be enlarged; Prompts should also be made for products that need to be painted or protected. In short, the sheet metal processing process must be completed in strict accordance with the processing procedures.
Automotive interior plastic parts molded parts generally require high productivity with one mold and multiple cavities. Large molds can reach hundreds of cavities or thousands of cavities in one mold. It requires mold processing equipment with a large workbench with strong bearing capacity, high rigidity, and high consistency. The mold steel material processed by automotive interior plastic parts has high hardness, which requires mold processing equipment to have thermal stability and high reliability. For complex cavities and multi-functional composite molds, with the diversification of the shape of the parts, aluminum die casting for automobiles must improve the design and manufacturing level of the mold.
The processing process of automobile sheet metal parts mainly includes CNC programming blanking, bending, riveting, welding, spraying, packaging, and other processes. The process of sheet metal processing is a combination of theory and practice. It is a production process that organically combines the basic process knowledge, basic process methods, and basic process practice of mechanical manufacturing.
Aluminum dies casting for automobile repeat positioning accuracy, linear feed speed in automotive interior plastic parts three-dimensional surface processing, and aluminum die casting for an automobile can not reflect the actual aluminum die casting for automobile processing conditions. The high-precision machining of the three-dimensional curved surface of the mold also puts forward the requirements of high dynamic precision performance. High speed and high precision can only be realized with the cooperation of high rigidity, thermal stability, high reliability, and a high-quality control system of the machine tool.
