Hole punch has sheet metal housing and pressure lever formed as one compact unit from resilient spring steel

摘要

The hole punch has a shaped sheet metal housing (1) containing two or more displaceable punching rams operated by a pressure lever (4). The housing and pressure lever are formed as one compact unit made from resilient spring steel shaped into a monolithic component. The housing can have in its central area a bead-like reinforcement (2) with two perpendicular guide bores in which the rams are mounted.
