Abstract
PURPOSE: To save material and lower material cost by performing the shoulder-form build-up of right and left end through extrusion of the material thickness from the inner part by driving deep recesses in the perpendicular end part.
CONSTITUTION: An opening part 2 of the specified size is formed in the lengthwise direction in the central part of a bar material 1 as annealed, whereby a body 3 is made. Short perpendicular end parts 4, 4 are formed on the both right and left ends of the body 3. Next, arrow dies are driven deep at the same time in these perpendiclar end parts 4, 4, whereby the deep recesses 5, 5 are formed. As a result of this, the material thickness of the perpendicular end parts 4, 4 is pushed to the inside and the root end parts of the perpendicular end parts with the body force spread and build up, thereby forming gentle shoulder-form shoulder parts 6, 6. Through-holes 7, 7 are provided in the deep recesses 5, 5 formed at the shoulder parts 6, 6 of the body 3 through piercing with a blanking press and screw threads 8, 8 are provided in these through-holes 7, 7 by performing threading.
