PURPOSE:To disconnect feed bar from taper block and automatically disconnect the feed bar by feeding pressure fluid and letting cylinder move upward. CONSTITUTION:When pressure fluid is supplied to a pressure fluid feed hole 9c, the cylinder 9 moves upward and the ascending of the cylinder 9 is defined by a hook part 13a. If the pressure fluid is fed further, a taper block 11 descends together with a piston 10. This operation causes the tapered surfaces 11a, 11b of the taper block 11 to disconnect from the tapered surfaces 1a, 2a of the feed bar. The feed bar 1 is put in the unrestrained and freely held state. Following to this, the feed bar 1 on the corbel side is moved upward by, e.g., the uperward operation of a moving bolster, and is carried out in the horizontal direction together with the dies by the travelling operation of the moving bolster in the state that it is disconnected from a feed bar rest 12, taper block 11, remaining side feed bar, etc. |
