[0034] In the present embodiment, a stamping device for a door and window connecting piece is provided. By installing a push plate in cooperation with a return spring, the elastic deformation force of the return spring can eject the push plate after the workpiece is stamped.

[0035] The working principle of the above embodiment is as follows: first, the workpiece is placed on the lower die 14, at which time the hydraulic rod 10 pushes the punch 2 up and contacts the workpiece, at which time the pressure applied by the punch 2 will push the top plate 15 down, and the top plate 15 will compress the buffer spring when it descends, and at this time the slide bar 19 can limit the top plate 15 so that the top plate 15 can slide stably, and by installing the limiter 20, the descending distance of the top plate 15 can be limited to prevent the top plate 15 from continuing to descend, and when the top plate 15 is in place, pressure will be applied to the workpiece to complete the stamping, and when the punch 2 contacts the workpiece, the push plate 4 will return to the sliding groove 3 and contact the punch. 2 is in a horizontal state and compresses the reset spring 6. When the punching is completed, the punch 2 will be away from the workpiece. At this time, the elastic deformation force of the reset spring 6 can push the push plate 4 to pop out to prevent the workpiece from adhering to the punch 2. When the punch 2 is reset, the elastic deformation force of the reset spring 6 can push the top plate 15 to reset and pop out the workpiece during the reset to prevent the workpiece from being retained in the lower die 14, thereby achieving the purpose of automatic material withdrawal. When the stamping is completed, the air pump 12 drives and conveys airflow to the two bellows 8 through the three-way pipe 13, so that the airflow can be ejected from the nozzle 9 to clean the lower die 14 to prevent impurities from being retained on the lower die 14.
