Mechanical flanging device for machining complex part, has spring that is compressed using fitting screw, so that device is equipped before its usage, where screw is unlocked, and lever for maintaining compressed spring

摘要

The device has a spring (2) that is compressed using a fitting screw (1), so that the device is equipped before its usage. A pivoting arm (3) is rotated using a cam (8). A piston (9) permits a lever retention block (10) to lock a lever (4), where the block has a return spring (11) and a safety lock (12). The screw is unlocked, and the lever maintains the compressed spring.
