[0002] Relays are usually composed of electromagnetic coils and one or more contacts that can be switched on and off. They are widely used in automated control circuits and play the role of automatic adjustment, safety protection, circuit conversion, etc. Hot stamping is an important process for manufacturing certain metal parts of relays.

[0003] The stamping mechanism usually includes a processing table, a support block, a transmission device, a fixed frame, an operating table, a hydraulic device, a base, and a stamping table. During the stamping process, the metal raw material is first placed on the working table of the stamping mechanism, and then the material is sent to the stamping area through the transmission device.

At the same time, the mounting box drives the strip to move to the lower die until the upper die and the lower die are molded together to stamp a part of the strip to form the required parts. Then the half gear with teeth is separated from the tooth plate, and the No. 1 spring pushes the limit rod to drive the mounting plate to slide up. At the same time, the mounting plate pushes the push rod through the connecting rod to drive the slider to slide in the slide rail. At the same time, the push rod pushes the push plate to eject the parts lifted from the lower die by the No. 3 spring from the ejector to exit the stamping mechanism, and then the feeding and stamping operations are repeated to perform the next stamping. The structural design realizes the function of automatic material withdrawal, which solves the problem that the existing stamping mechanism material withdrawal device structure is more prone to mechanical or electrical failures due to its complex structure containing more parts and connection points. This reduces the reliability of equipment and increases the uncertainty and risk in the production process. BRIEF DESCRIPTION OF THE DRAWINGS
