Abstract

PURPOSE: To get a conductive coupling without requiring costly processes, by forming a cylinder through extrusion of aluminum alloy and then continuously processing from drilling to screwing.
CONSTITUTION: An aluminum alloy is extruded to form a cylinder 2 having a bed 1 along the length. Through holes 4 reaching inside the cylinder 2 are made on the bed 1 by means of punches 8k and then the cylinder 2 is cut off by a press cutter 9 to form a coupling body 3. After chasing female thread 5 on the holes 4 and fitting setscrews 6 there, surface treatment is done to finish a coupling A. This continuous manufacturing method does not require any sophisticated device to get a highly conductive coupling.
