Abstract

The utility model provides a stamping device for preventing products from sticking, which is characterized in that a plate to be stamped is placed on a lower stamping die, the driving end of a stamping machine drives an upper stamping die to move close to the lower stamping die through an upper bearing seat, and the upper stamping die is combined with the lower stamping die to stamp the plate to be stamped. In the process, the punching needle slides along the punching hole and drives the sliding block to slide along the sliding cavity and compress the compression spring to move, and the limit sliding column moves along the second sliding groove. Because of the strong pressure, a vacuum exists between the plate and the stamping upper die, and under the action of atmospheric pressure, the plate may adhere to the upper die. When the driving end of the punching machine drives the upper punching die to move away from the lower punching die through the upper bearing seat, the compression spring recovers elastic deformation, and the punching pin is driven by the sliding block to expose and punch the plate from the upper punching die. The stamping device for preventing the product from sticking can wash the stamped plate out of the upper stamping die, so that the production efficiency of the stamping device is increased.
