Abstract
PURPOSE: To obtain a blank material for working with virtually no losses by cutting of raw material by pressing a wire material which is smaller in diameter than the minimum diameter of a female die of a press and has been shorn to a prescribed weight with a male die of the press.
CONSTITUTION: A round wire material 1 of Al, Zn or the like which is smaller in diameter than the minimum diameter (a) of a female die 2 of a press is shorn with a shearing blade 3, whereby a shorn material 4 is formed. The length thereof is so set that the same weight as that of an intended blank material (slab) 5 is obtained. The material 4 is placed upright and is carried to the female die 2 of a press machine 6. The die 2 has an ejection bar 7 in the bottom part, is formed with a radius on the connecting part between the bottom surface and the side face and its size corresponds to that of a female die 8 for impact extrusion. The material 4 erected in the die 2 is pressed by a male die 9 of the press and is thereby formed to a slab which is removed by being ejected upward with the rod 7. The top and bottom of the slab 5 are clearly identified by the radius of the bottom surface or the trace 10 of the rod 7, and at the time of pressing the same with the male die 12 in the die 8, the position of the burrs produced in a work piece 13 is brought to the top end part of the work piece 13.
