PURPOSE:To improve safety in the work as well as preventing the die damages with the sure unloading of a workpiece by the jump-up of a placing plate which is locked by the ascent and descent of an upper die by providing a die and inclinable workpiece placing plate to a lower die and a punch and metal fitting locking the placing plate to an upper die. CONSTITUTION:An inclining lever 34 is inclined against a spring 45 with the abutting of the guide face 46 of the lever 34 to a jumping up edge 17 together with the descent of an upper die 7 and a locking face 42 is positioned on the lower part of the jumping up edge 17. A locking fittings 6 locks the jumping up edge 17 at its locking face 42 and jumps up a placing plate 2 in case of the upper die 7 stopping its ascent after completion of the press working. A workpiece W is therefore released from a positioning piece 26 and pin 24, slipped down toward the shaft supporting side together with the inclination of the placing plate 2 and unloaded surely. When the upper die 7 is further ascended, the jumping up edge 17 is removed from the locking face 42 and the placing plate 2 is returned to a horizontal condition by the spring 21. |
