Abstract
PURPOSE: To hold a well-balanced state and also to raise wear proof, by working stee ingot to a doughnut-like rolling rough material, forming a rim ring in the form of U by means of rolling mill forging, forming a boss and a web in one body by a stamp hammer, and making the tip of the web and the rim ring coincide linearly as a pair.
CONSTITUTION: Heated steel ingot is worked to a doughnut-like rolling rough material 4 through such processes as swaging, punching and extend hollow forging. At the same time, by means of rolling mill forging, a rim ring 1 is formed in the form of U so that an internal surface (a) of the rim ring 1 is thicker than an outside circumferential end edge part (b), and a projecting neck part P is provided on its opposite surface side. Subsequently, a web 9 and a boss 10 are formed in one body by a stamp hammer, so as to be linear in the same vertical direction. The tip of the web 9 and the projecting neck part P of the rim ring 1 are made to coincide linearly as a pair, and both right and left sides of its junction part are welded.
