Abstract
PURPOSE: To accurately form ball grooves on a prescribed spherical surface so that after workings are eliminated and the consumption of the material is reduced, by performing a press forming on crude materials for making outer rings with a die set composed of a combination punch made of specified members and a drawing die.
CONSTITUTION: The whole body of a combination punch 3 is lowered through a press driver 6, and a crude material for making the outer ring W is formed to have a prescribed shape with dies 1 and 2, a split type punch 7, and a taper base 9. A front end punch forms the bottom part We of the inner curved surface. When a press slide 6 is lifted up after the forming is completed. The front end punch 8 and the split type punch 7 compress a spring 10 and remain in the crude material W in dies 1 and 2. When the maximum diameter part of the curved surface forming swelled part of the split punch 7 is shrinked smaller than the inner diameter of the opened part of the crude material W after forming when the taper base 8 and a supporting means 11 are lifted up, the punches 8 and 7 return to the original position together with another front punch 6 by means of the stored restration elasticity of the spring 10, and completely come out from the crude material W for making the outer ring. Then, the crude material W is pushed out from the dies 1 and 2 by a knockout pin 4.
