Abstract

PURPOSE: To make the simultaneousness, equal speediness, etc. of a pair of punches sure, by defining the relations of the respective forcing in of rams for punches as the rams for punches advance and receiving bars move the oil in oil chambers.
CONSTITUTION: The distance between the both ends of a push bar 17 and receiving bar 18 is constituted equal to the distance between the end faces of an upper die 4 and lower die 5. The restraining relation by the contact of the push bar 17 and receiving bar 18 is created with respect to the respective working strokes of rams 7 and 13 for punches. Namely, if the diameter d1 of the receiving bar 18 and the diameter d2 of a plunger 22 are equal, the forcing size of the pump 7a and the forcing size from the opposite direction of the punch 13a become exactly equal and this relation is accurately maintained without having no relation to the errors in the forcing force acting upon the respective rams 7 and 13 for punches through pipings 14, 15 or the existence of the unevenness of resistance of the material 6 against plastic deformation. Hence, the forcing size of the punch 7a for the material 6 and the forcing size of the punch 13a are accurately equal and the forcing starting point and forcing speed are exactly equal as well.
