Abstract
PURPOSE: To prevent lowering of stiffness and fracture, without causing excessive strain, even in the case of a relatively long spindle, by providing fitting grooves in the depression rod in the side wall of a cylindrical body parallel to the center line thereof symmetrically with respect to the diameter at specified intervals in parallel arrangement.
CONSTITUTION: When the work is inserted between dies 20, 20, and a motor is started, the spindle rotates in the direction of arrow 22. Due to this rotation, when the outward curved wall 7a of a backer 7 comes to the position of a hardening roller 12, the backer 7 is deformed by the extent of protrusion of the outward curved wall 7a to push a depression rod 4 in the direction of arrow 23. As a result, the depression rod 4 presses the dies 20 with its inner end. The dies 20, 20 are pressed by the depression rods 4, 4 provided symmetrically with respect to the diameter so as to approach to each other, thereby processing as intended. Therefore, by sequentially changing the inside forms of the dies 20, 20 the work is processed in the appearance corresponding to the inside form of the dies as the process advances, and is taken out from the opposite side of the inserting direction.
