Single shaft punch press |
摘要 |
Four lever units are linked to the arrangement of connecting rods via a common bolt. Each lever unit drives one ram of the punch press. The rams are arranged in configuration of a square. This allows a much higher loading by off-center forces and the punch press can be designed for a given punch press output with considerably smaller dimensions.
