| 摘要 |
The present invention relates to single actuator blanking and draw pad force control for a drawing press, which includes a unique swivel for the hold down pad comprising a confined elastomeric member which has high axial stiffness, but relatively low rotational or pivoting stiffness about an axis normal to the actuator axis. Further, the pad can be combined with air pressure for holding a sheet of material during the blanking and drawing operations.
