Abstract
PURPOSE:To start the formation of the groove placing a time difference, and to form plural grooves in the circumferential plane of the rod type blank, by employing a moving die and a stationary die both being provided with plural edges dislocated in the longitudinal direction. CONSTITUTION:At the starting point of the stationary die 6, the rod type blank 1 is inserted. Next, when the moving die 12 is moved while being pushed downward, the blank 1 rolls, and the formation of the groove 2 is started by the edges 10a, 14a. At this point, the forming action of the chamfering edges 7a, 9a, 13a, 16a, is not started yet. Then, if the blank 1 is further rolled, the formation of the groove 2 is finished, and next, the formation of the groove 3 is started by the edges 11a, 15a. The blank 1 is further guided by the guides 10b, 14b, and the edges 7a, 9a, 13a, 16a, become active; hereby, the chamfering of both sides is started, and finally the product is obtained.
