Abstract
PURPOSE: To manufacture a highly accurate pipe for connector at low cost by forming a metallic round bar to a pipe by plastic deformation and after punching unnecessary part, forming tapered faces at both ends.
CONSTITUTION: A metallic round bar 10 is inserted into a die 12 provided with a forming hole, and the part above the first punch is formed to a plane and the lower edge is formed to a form that conforms to a circumferentially recessed groove 14. The round bar 10 is turned upside-down and the second punch 18 having a tapered face 2c is inserted and pressed to form a recessed hole 20 at one end of the round bar 10. It is then turned upside-down and a forming pin 22 is inserted into the hole 20. At the same time, it is pressed using the third punch 24 to form an auxiliary concave hole 26. Next, a punching pipe 29 is inserted and a punch 30 is inserted into the hole 20 to punch the thin part 27 and pass through a pipe hole. Then, a finisher is inserted to make plastic deformation of both ends of inside of the round bar 10 and a metallic pipe having a tapered face is completed.
