Abstract

PURPOSE: The pressing device which makes possible dies exchangeable to a pillar within a short time by installing guide bars to the top of the bolster and providing pin-slide-type locking devices to the ram and guide bars or other.
CONSTITUTION: The die to be mounted with its upper die 14 and lower die 15 being assembled vertically is placed on a conveyor 10. On the other hand, a movable bolster 3 is moved to the opposing position of a conveyor 10. Next, the foregoing die is slided between the guide bars 12, 13 on the bolster 3 and is placed in the home position. Thence, in this state, pin-slide-type locking devices 22A are operated to protrude insertion pins 25 and engage the same into the engaging holes 18 of the side plates 17 of the lower die 15, whereby the die is fixed onto the bolster 3. Next, the bolster 3 is moved in the operating position by operating a cylinder 4 and a ram 7 is lowered. At the same time, pins 25 are inserted into engagement holes 40, whereby locking of the ram 7 and upper die 14 is completed. The ram 7 and upper die 14 are then detached from the lower die 15 and are raised, the work is placed on the cutting blade 15a of the lower die 15, the ram 7 is lowered and the pressing is applied to the work between the upper die 14 and lower die 15.
