Positioning design of metal stamping parts

When placing strips or workpieces, the blanking die should maintain a certain relative position with the cavity to ensure that the edges are correct or the punching and trimming positions are accurate. Therefore, there should be enough positioning devices in the mold. The main types of positioning devices are positioning pins (rods), positioning blocks and positioning plates. Regardless of the positioning device, consideration should be given to many factors such as reliable positioning, meeting the required positioning accuracy, and convenient handling of parts or strips. Pin positioning design techniques (1) Fixed stopper pins use cylindrical pins or big-end pins as the positioning device for the side or feeding direction of the sheet. The fixed stopper pins are generally set on the die or elastic discharge plate. When one piece is installed with a stopper pin, the other piece must be provided with an escape hole.　　(2) Elastic stopper pin 　　 When the avoidance hole affects the strength of the cutting edge on the die, an elastic stopper pin that does not have to avoid the avoidance hole can be used.　　(3) Hook type stopper pin 　　 Elastic stopper pin. Although the fixed stopper pin can solve the problem of the strength of the die caused by the stopper pin hole, the strip must be lifted before it can be fed. When a fixed unloading plate is used, a hook stopper pin can be used.　The quality of metal stamping parts directly affects the stamping process design and the quality, service life and cost of metal stamping parts. Therefore, in addition to improving the manufacturability of metal stamping parts, improving the conditions of stamping deformation, and reducing the requirements for materials, we must also strive to improve the quality of stamping parts to adapt to the requirements of the stamping process in order to produce excellent stamping parts. The basic requirements for metal stamping materials. From the perspective of the use of high-pressure reciprocating pumps, different products have different requirements for the mechanical properties and physical properties of the materials. For example, mechanical and instrument parts should have certain strength, stiffness and impact toughness; chemical and medical instrument parts should have corrosion resistance.
