摘要:
In an apparatus for blanking out a sheet material (1) between a punch (4) and a die (6) having a sharp edge (7), the punch (4) is formed by a heterogeneous composite elastic material having localized regions (4a) having a relatively higher hardness, and complementary regions (4b) having a relatively lower hardness.
