Abstract

PURPOSE:To save the trouble of setup and to minimize danger by making piercing of holes for inserting bolts on two faces of the object to be worked such as a square steel tube at a time. CONSTITUTION:A die 3 having a specified hole diameter is set to a sliding block 13 provided with a key. After attaching punches 2a, 2b to guides 8a, 8b respectively, an object 4 to be pierced such as a square steel tube is inserted into the die 3 until it contacts with a positioning pin 15. After that, by extending hydraulic cylinders 7a, 7b, the guides 8a, 8b move to the die 3 along guide bars 9a, 9b together with punches 2a, 2b. Two faces of the object 4 to be worked such as a square steel tube are pierced at the same time by the punches 2a, 2b.
