Japanese Patent JP7169891
Kind Code:
B2
Abstract:
To control an angle formed in a workpiece into a desired shape.SOLUTION: In a processing device 1, a punch 10 inserted in the inside of a cylindrical part 101 pushes a bottom wall 101a of the cylindrical part 101 in an axial direction, and a pad 20 pushes one end 101b of the cylindrical part 101 in the axial direction, in a state in which a collar part 102 of a workpiece 100 having the cylindrical part 101 inserted in a punch insertion hole 21 is in contact with an upper end surface 32 of a die 30. An ejector 40 pushes the bottom wall 101a of the cylindrical part 101 in the axial direction toward the punch 10 side against force of the punch 10 that pushes the bottom wall 101a of the cylindrical part 101.SELECTED DRAWING: Figure 5
