Abstract
The invention discloses a high-speed progressive die anti-scrap bouncing cavity die, comprising a cavity die body and a cavity die edge arranged on the cavity die body. The cavity die is characterized in that the cavity die edge is a circular opening, the upper section of the cavity die edge is an edge cut-in section with edge cut-in depth, an annular rough layer which is arranged below the edge cut-in section is arranged on the inner wall of the cavity die edge, and an alloy granular layer covers the rough layer. In the invention, since the rough layer and the alloy granular layer are arranged below the edge cut-in depth of the cavity die edge, the friction coefficient is increased and the occlusal force to scrap is improved. When extruded into the cavity die edge by a terrace die, the scrap is tightly occluded with a smaller cavity die, thus scrap bounding is prevented; the problem of scrap bounding during blanking of a progressive die at the high speed of 200-1500r/min can be solved, thus scrap bounding is avoided, the occlusal force to the scrap is improved, the production efficiency of finished products is improved, and the defective rate and production cost are reduced.
