[0002] During the relay production process, some parts need to use stamping equipment to plastically deform the metal materials in order to manufacture parts with specific shape and size requirements. In relay production, the stamping process is mainly used to manufacture relay shrapnel, contact points and other components. In the current relay shrapnel production process, in order to improve production efficiency, stamping equipment will be used for batch stamping. In the process of batch stamping, a whole copper plate is usually selected for multiple stamping.

[0003] According to the "A Relay Production and Processing Stamping Die" with Chinese Patent Publication No. CN217889274U, it mainly describes that automatic unloading can be achieved through the cooperation of the screw rod, motor, second cylinder, lifting plate, movable cavity, ejection block, push plate, screw sleeve, leakage trough and collection box. The operation is convenient and efficient, which improves work efficiency. At the same time, the relay production and processing stamping die can conveniently guide the lifting plate through the limit blocks and limit grooves, thereby increasing the stability of the lifting plate. The stagnation plate is convenient for supporting the push plate. The guide grooves and guide blocks are convenient for increasing the stability of the push plate. In this process, the stamping equipment needs to spend time pushing the stamped parts into the leakage trough and the collection box through the push plate during stamping, which affects the efficiency of stamping.

[0004] Therefore, a relay production stamping die is proposed to solve the problem that in the process, the stamping equipment needs to spend time pushing the stamped parts into the leakage trough and the collection box through the push plate during stamping, which affects the stamping efficiency.

Fixed plates 9 are fixedly connected to both sides of the upper end of the base 1. A second electric push rod 10 is fixedly connected to the fixed plate 9 and a contact plate 11 is fixedly connected to the output end of the second electric push rod 10. A feed trough 12 is provided on the bottom side of the base 1. The second electric push rod 10 drives the contact plate 11 to move and contacts the upper side of the rotating column 7, thereby providing support and achieving stable stamping. A first groove 17 is provided in the bottom mold 8 and a limiting sleeve 18 is fixedly connected in the first groove 17. A spring rod 19 is inserted on the limiting sleeve 18. One end of the spring rod 19 is fixedly connected to a first cushion block 20, and the other end of the spring rod 19 is fixedly connected to the second cushion block 21.

[0018] The upper arc surface of the rotating column 7 corresponds to the arc-shaped inclined surface, and the arc-shaped inclined surface is located on the contact plate 11. The arc-shaped inclined surface is arranged to fit with the rotating column 7 to provide stable support.

[0019] The bottom mold 8 is twice as long as the clamping groove, and the bottom mold 8 corresponds to the clamping groove. The clamping groove is evenly located on one side of the inclined surface of the contact plate 11. By setting the clamping groove, the tightness of the contact is improved.
