Abstract
PURPOSE: To maintain the joint rigidly by simultaneously press forming flange section and an arcuate groove along the joint between said flange section and rod section through a die thereby preventing the collapse of joint of metal structure at the press roll section of material.
CONSTITUTION: The shaft 1 of caster wheel, for example, is composed of a flange section 2, rod section 3 and a projected section 5 where such as a bearing is applied on lower conical face of the flange section 2. In order to form said shaft 1, a die 14 having a circular convex section 13 required for forming a circular groove 5 is used, where a material for forming the shaft 1 is press rolled in the direction of arrow A to obtain a shaft 1 having a circular groove along the circumference at the root of said flanges section 2. In such a shaft, the flow line B showing the fiber flow is not broken on the outer face of the shaft 1, thereby the metal structure continues preferably resulting in the improved strength at the roll press section.
