| 摘要 |
The invention relates to a control device comprising a first and a second tool (23, 24) of which one forms the male mold and the other forms the female mold. The control device also comprises a first pneumatic or hydraulic piston-cylinder assembly (12), which is controlled by a setpoint generator that is rotatably driven about a drive shaft (5) and which is provided for driving the first tool (23) toward the second tool (24). In order to also be able to punch out fine components made of thin material at a high cutting speed, the invention provides a second piston-cylinder arrangement (13), which is controlled by a setpoint generator that is rotatably driven about the same drive shaft (5) and which works in a direction opposite to that of first piston-cylinder assembly. This second piston-cylinder arrangement uses motion transfer means to drive the second tool (24) toward the first tool (23). |
