Abstract

PURPOSE: To appropriately adjust the pressure to be applied to pierce nuts in accordance with the thickness of plates, by installing a pierce nut working device provided with a pushing means to a tarret punch press.
CONSTITUTION: By contracting a hydraulic pressure cylinder 119, unrequisite dies are lowered and only dies which are going to perform a pierce nut working, are kept at the higher level. Then the stroke of a punch 11 is set by automatically adjusting the stroke of a pushing means 47a of a pierce nut working device 23 to the thickness of a platy work. Moreover, the device 23 is installed to each pushing means 47b and 47c, so that a simultaneous working of pierce nuts may become possible. Although the stroke of a hydraulic pressure cylinder 51 which drives the punch 11 is set at the upper limit before the working is started and after the working is completed, the cylinder is set to make a reciprocating motion between the bottom dead center and the central position during the course of continuous working. In this way, pierce nuts successively supplied on the work are struck by the punch 11 and thus the pierce nut working is performed.
