ス。 A hollow die stand whose body is detachably attached to the holder is divided equally into three in the circumferential direction by providing a slit from its tip to the body.
Rolling rollers are rotatably supported at equal intervals on each divided piece, and the tip of the die stand is formed into a tapered truncated conical shape, and an adjustment cap screwed into the holder is screwed back and forth. A rolling die characterized in that the tapered surface of the outer periphery of the tip is brought into contact with the inner periphery of the opening of the adjustment cap so that the distance between the centers of the rolling rollers can be adjusted.
