Abstract
PURPOSE:To facilitate positioning and improve efficency of assembling and accuracy of products by making cutting and bending from the end face of a cylinder by an edge moving plural punches in axial direction and forming a bent piece. CONSTITUTION:A base valve 4 is inserted into a cylinder 1 until it is caught by a step 2 and set on a stand with the end face to be worked of the cylinder 1 facing the edge part 12 of each punch 8. When an actuator is driven, plural punches project in axial direction of the cylinder 1 and inserted in the end of the cylinder 1. When the edge part 12 arrives at the end face of the cylinder 1 while the outer periphery of the cylinder 1 being pressed by a guide 13 of the punch 8, cutting is made by both edge faces in the axial direction. At the same time, bending is made to the inside with a specified curvature R by a pressing part 14. The bent piece 3 is pressure welded to the end face of the base valve 4 by the pressing part 14 and caulked.
