Abstract

The invention discloses a high-efficiency stamping die, which includes an upper template and a stamping head assembly arranged on the upper end of the upper template. The stamping head assembly includes a stamping rod, a backing plate and a punch. At the lower end of the rod, a concave cavity is provided in the middle of the upper template facing the position of the punch head assembly, and a relief groove is opened on the upper template on one side of the concave cavity, and a rotating shaft is arranged on the upper end surface between the concave cavity and the relief groove , a fixed plate is arranged at both ends of the rotating shaft, and two pressure blocks are arranged at the upper end of the fixed plate. In the present invention, by setting more than one rotatable fixed plate, the workpiece is clamped continuously, and the outer wall of the stamped workpiece is limited by the movable baffle and the fixed baffle during the stamping process, so as to prevent the stamping of the workpiece after stamping is completed. Because the impact speed of the punch is too fast, the outer surface of the workpiece is extruded and deformed, which makes the outer wall of the workpiece more beautiful after stamping, and the upper end surface of the workpiece will not warp, so the efficiency is higher.

Description

A high-efficiency stamping die

technical field

The invention relates to a high-efficiency stamping die.

Background technique

When the workpiece is being processed, it is necessary to use a stamping die for stamping and deformation to obtain an effective semi-finished product. In the prior art, when the workpiece is stamped, due to the high impact speed of the punch, the protruding part of the stamped workpiece usually has uneven outer walls. situation, or during the stamping process, the fixed parts at both ends of the workpiece will be lifted. This is because the punch is located in the middle of the workpiece. When the punch is pressed down, the two ends of the workpiece will be lifted, although the upper end is fixed , but there will still be slight deformation. And the existing punching method is often to punch a workpiece first, and then clamp after the punching is completed, which wastes a lot of time.
