    摘要： In a brake-disc intermediate product, a corrugated portion is molded using an upper mold and a lower mold. The brake-disc intermediate product is set in a mold, the mold has a slope corresponding to the corrugated portion, and an angular portion formed along the outer circumferential edge of the corrugated portion is in contact with the slope in a state where the brake-disc intermediate product is set in the mold. The angular portion in contact with the slope is deformed by pressing the brake-disc intermediate product in a direction of the mold, to mold a chamfer portion. The slope is formed so that a chamfering angle formed with respect to an inner bottom surface of the mold is larger at a portion in contact with the concave portion than a chamfering angle at a portion in contact with the convex portion.

    摘要： A process for bending on a press a metal sheet through a desired angle and an inner bend radius less than the thickness of the sheet, without causing damages such as cracking in a bend. According to this process, a metal sheet is first bent through an angle approximating a desired angle, with an inner bend radius being greater than the thickness of the metal sheet, and then the metal sheet thus bent is further bent through a desired angle, with the inner bend radius being less than the thickness of the metal sheet, and with the stretching of a material of the metal sheet on the outer side of the bend being suppressed.
