Different characteristics and scope of use of stamping parts

The shape of metal stamping parts should be simple and symmetrical, and the depth should not be too large. In order to minimize the number of deep drawing, easy to shape. The fillet radius of metal stamping parts does not increase the process procedure. Otherwise, it will inevitably increase the number of deep drawing and shaping work, and also increase the number of molds, and it is easy to produce waste and increase the cost. Whether the mold used for metal stamping parts adopts an elastic discharge plate or a fixed discharge plate depends on the size of the discharge force. , The material thickness is the main consideration. With the enhancement of the elastic force of the elastic element used in the mold (such as the use of a rectangular spring), the discharge force of the elastic discharge plate is greatly enhanced. Metal stamping parts are forming processing methods that rely on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of the required shape and size. What aspects of the metal stamping parts processing industry should develop: During the development of metal stamping parts processing technology, the process parameters and the shape and size of the working part of the die should be correctly determined to improve the quality of stamping parts and shorten the trial production cycle of new products. It should be strengthened On the basis of the research of stamping forming theory, the stamping forming theory can be used to guide the actual production, and a set of advanced process analysis and calculation methods that are closely integrated with the actual production have been gradually established. Foreign countries have begun to use the elastic-plastic finite element method to cover automobiles. Perform stress and strain analysis and computer simulation in the forming process of parts to predict the possibility of a certain process plan for forming parts and possible problems. Speed u200bu200bup product upgrading and overcome the shortcomings of long mold design cycles. Mold computer-aided design should be vigorously carried out And manufacturing (CAD/CAM) technology. In China, special attention should be paid to strengthening the research of multi-station progressive CAD/CAM technology. To meet the needs of mass production and reduce labor intensity. The mechanization and automation of stamping production should be strengthened. It enables general medium and small parts to be produced on high-speed presses with multi-station progressive dies, achieving a high degree of production automation, and further improving the productivity of stamping. Expand the scope of application of stamping production. Make cold stamping suitable for both mass production and small batches Production; it can produce both general precision products and precision parts. Attention should be paid to the development of new forming processes such as precision blanking (especially thick material precision blanking), high-energy forming, soft mold forming, pressure and superplastic processing, etc. Also promote the use of simple molds (soft molds and low melting point alloy molds), general combined molds, CNC punching machines and other equipment.
