摘要： A cutting device for a thin metallic plate is provided which shortens time for shaping or the like on a cut edge to improve manufacturing efficiency, and increases the life of a cutter. The cutting device for cutting a thin metallic plate W with a predetermined width includes a shearing cutter 7 which is made of a metal having a higher hardness than the thin plate W and has a blade angle of 50 to 90°. A contacting member 5 is provided which includes a groove 8 facing the shearing cutter 7 and makes contact with the back side of the thin plate W. In the groove 8, an interval a between upper edges 9a and 9b of inner walls 9 is set at 15 to 30 times a thickness b of the thin plate W. A depth c of a deepest portion 11 in the groove 8 is set at one to three times the thickness b of the thin plate W. The inner walls 9 of the groove 8 include curved surfaces 10, each of which has a curvature radius of 15 to 50 times the thickness b of the thin plate.

摘要： A forge-molding method for forming a constant velocity joint outer ring comprising a shaft and a cup formed integral with and expanding radially and outwardly from one end of the shaft is provided. The method uses an ironing die apparatus which is provided with a lower molding die, an upper molding die and an ironing punch. The lower molding die is provided with a first cavity formed to have a final degree of product accuracy with respect to the shaft and adapted to apply a final ironing process to the shaft, while the upper molding die is provided with a second cavity for restraining the outer peripheral surface of the cup. Consequently, the accuracy of concentricity between the shaft and the cup can be securely maintained in a simple manner and a sufficient degree of accuracy of the inner peripheral surface and/or the inner diameter of the cup can be effectively secured.
