Abstract

PURPOSE: To make finishing of splines well by forming approximate splines with rollers then finish forming with finishing dies.
CONSTITUTION: When a cup-shaped work piece 17 having a cylindrical circumferential surface is held to the tip of a punch 2, and a die holder 3 is moved in the direction of the punch 2, the tip of a press pin abuts on the bottom of the work piece 17 and holds the work piece 17. When the die holder 3 is driven further, the rollers 9 of the 1st row contact the cylindrical circumferential surface of the work piece 17 and pushes it in the groove 2a in the axial direction of the punch 2. Further, the rollers 9 of the 2nd row and 3rd row successively engage with the work piece 17, thereby pushing the work piece 17 gradually deep into the grooves 2a. Finally a finishing die 7 engages with the work piece 17 and sandwiches the work piece 17 between its inside circumferential surface and the outside circumferential surface of the punch 2, thereby finish-forming splines on the circumferential surface of the work piece 17.
