Abstract
PURPOSE: To make the control of the sizes of the blank and the finished product to be easy, to make the welding work unnecssary, and to improve the productivity, by forming the inner surface of the sheet blank into the continuous smooth plane.
CONSTITUTION: The drawing work is applied to the sheet blank 1 and the bottomed cylindrical shape is obtained. The bottom of this bottomed cylindrical shape is drawn inward, and the corner radius R of the turn-up is eliminated by the restriking work. The bottom of this restruck shape is removed by the trimming work and is scrapped 3. Next, the inward turned up part is shaped by the burring work into a shape whose inner circumference is opening toward both of open mouths. The flange formed in a outer circumference is cut off by the trimming work and is scrapped 4. The trimmed part is bent inward; and finally, the neck formed by the restriking work is pressure welded to the end of the part forming the inner circumference, and the inner surface is finished into the continuous smooth plane.
