[0031] A plurality of triangular protrusions 13 are fixedly installed in the groove of the blanking plate 5, and the plurality of triangular protrusions 13 are arranged in a triangular shape. The top surface of the bottom plate 1 is fixedly provided with an inclined plate 6, one end of the inclined plate 6 extends below the blanking plate 5.
