Abstract

PURPOSE:To manufacture ring-like parts having a good yield and high dimension precision of the inside circumferential face, by a utilizing extrusion and ironing instead of conventional machining, when manufacturing the ring-like parts having an outward flange on both ends. CONSTITUTION:First of all, a material to be worked such as steel, etc. is upsetted to a shape being similar to the outside circumference of desired ring-like parts. The material after upsetting is worked to ring-like parts having a flange part 4 whose one end part has a bottom part 2 and also which projects in the diameter expanding direction extending over the overall length round the circumference of the other end part 3. In this regard, the connecting part of the bottom part 2 and the ring part 5 is curved, and the bottom part 2 is made comparatively thin. Subsequently, the bottom part 2 is punched by leaving a projecting part 6 in the diameter contracting direction extending over the overall length in the circumferential direction. The formed projecting part 6 is ironed by applying a load so as to be deformed in the diameter expanding direction extending over the overall length in the circumferential direction, a flange part 8 is formed extending over the overall length in the circumferential direction, on the one end part 1, too, and ring-like parts being a final product are obtained.
