Abstract

PURPOSE: To considerably improve efficiency by continuously performing drawing, piercing and bead grinding with one unit of device.
CONSTITUTION: The work pipe 9 is carried in by a carry-in device 8, after which it is fixed with a clamping device 4. A drawing and bead grinding device 10 is advanced by a main cylinder 14 and the work is drawn with a cylindrical die 11. After the drawing, the drawing and bead grinding device 10 automatically stops and a punch cylinder 23 is operated to push in a punch 15, by which the drawing in the cylindrical die 11 is accomplished. After this, a bolt hole 25 is opened to the end of the work pipe 9. Next, when the drawing and bead grinding device 10 is retreated by operating the main cylinder 14, the beads 24 in the groove 21 of the core metal 13 are ground by a tool 22. At the same instant of this, the pipe end portion is slightly expanded by the core metal 13 of the outside diameter slightly larger than the inside diameter of the work pipe 9 end after the drawing, whereby the dimesional accuracy thereof is enhanced.
