PURPOSE:To easily take out a test-hit work from a metallic die, by providing a clutch between a crank shaft and a transfer feed device, and releasing the interlock of both by the clutch. CONSTITUTION:In case of a regular operation of a press machine, the right end part of a key member 4 of an operating lever 9 is inserted into a key insertion hole 13 of a driving pulley 12, the operation is executed, the driving pulley 12 is rotated together with an intermediate shaft 1, and accordingly, a feed cam shaft 14 of a transfer device, and a release cam shaft 15 are also interlocked. Subsequently, in case of test-hitting, the press machine is stopped once, and the interlock of the intermediate shaft 1 and the driving pulley 12 is released by drawing the key member 4 of the operating lever from the key insertion hole 13 of the driving pulley 12. As a result, the interlock between the intermediate shaft 1, and the feed cam shaft 14 and the release cam shaft 15 is released, the transfer feed device is set to a release attitude, and only the intermediate shaft 1 and a crank shaft S are rotated, by which test-hitting can be executed. |
