The present application changes the complicated operation of mainly relying on manual feeding in the traditional technology, and improves the feeding efficiency and stamping efficiency; 2. In the present application, the motor drives the round plate body, the waist-shaped plate and the push rod to rotate. Since the push rod cooperates with the one-letter opening on the transmission disc, and the arc-shaped side wall of the waist-shaped plate cooperates with the arc-shaped notch (and the arc-shaped side wall of the waist-shaped plate is coaxial with the round plate body), the push rod drives the transmission disc to move periodically and be stationary (when stationary, the stamping assembly completes the stamping of the end cap, and the suction cup type mechanical hand completes the action of sucking the round plate). This enables the equipment to run automatically. 3. In the present application, during the process that the roller and the sliding rod roll from the arc segment to the gradual change segment, the outer surface of the arc-shaped plate body abuts against the sphere and controls the connection column, the guide rod, the L-shaped rod body and the rack to move towards the side close to the axis of the machining table. This enables the gear to rotate, and under the action of the synchronous belt and the synchronous wheel, the center rod also rotates, so that the center rod drives the push plate to rotate, so that the push plate pushes the demolded end cap out of the discharge port from the machining table to complete the unloading action. Then, the roller resets to the arc segment along the gradual change segment, and the push plate also resets (only when the roller passes through the gradual change segment, the top block will rise and complete the demolding action, and when the roller does not reach the gradual change segment or has completed the unloading, there is no end cap on the top of the machining table to hinder the resetting action of the push plate), so as to perform the unloading action next time.
