PURPOSE: To improve the material yield and the quality. ;CONSTITUTION: This forging blank 42 is used at the time of forging a product having a prescribed thickness of a triangular shaped flange part at one end side of a cylindrical member, and has columnar part having flat plane shape as almost similar shape as the flange part of the product. That is, the forging blank 42 is manufactured to triangular columnar shape. By setting the forging blank 42 having triangular columnar shape in a forging die so that the material at the top points of the forging blank 42 flow to the top parts of the flange part in the product, the material does not exceed to the part corresponding to the side of the triangular shaped flange part in the product and the position which the unnecessary burr becomes large in the outer burr part, is eliminated.;COPYRIGHT: (C)1994,JPO&Japio
