    摘要： A ring molded article manufacturing method capable of reliably and efficiently producing a ring molded article in which dead metal regions are reduced, and a ring material used for producing the ring molded article, are provided. The present invention relates to the method for manufacturing a ring molded article having two convex portions which respectively protrude on both sides of the ring molded article in a direction of a center axis thereof and extend in a direction of a circumeference of the ring molded article. In the manufacturing method, the ring material is placed inside two molds on which concave portions respectively corresponding to the convex portions are formed, in a condition in which the ring material is supported by a region on an outer peripheral side from an outer peripheral side corner in the concave portion of one of the two molds and a region on an inner peripheral side from an inner peripheral side corner in the concave portion of another of the two molds, the ring material is then forged so as to be pressed by the two molds in a direction of a center axis of the ring material, and the ring molded article is thus produced. In addition, the present invention relates to the ring material used for producing the ring molded article.

    摘要翻译： 本发明提供一种能够可靠且高效地制造减少了死区金属的环成型品的环成型品的制造方法及用于制造该环成型品的环材。 本发明涉及具有两个凸出部分的环形模制品的制造方法，该两个凸出部分在环形模制品的两侧沿其中心轴线的方向分别突出并且沿着环形模制品的环绕方向延伸。 在该制造方法中，在将环形材料支承于外周侧的外周侧的区域的状态下，将环形材料配置在形成有与凸部对应的凹部的两个模具的内部 在两个模具中的一个模具的凹部中以及在两个模具中的另一个的凹部中的内周侧角部的内周侧上的区域中，然后锻造环材料以便被两个模具 在环材料的中心轴线的方向上，由此制造环形模制品。 另外，本发明涉及用于制造环状模制品的环材料。
