Abstract
PURPOSE: To simplify the mounting and dismounting of a jig and control the jig location against a core bar with the below-metioned guide by setting a store part for a core bar in part of a jig and setting jig guide interlocking with this core bar to allow in and out of the core bar against the store part.
CONSTITUTION: A core bar 17 is given a force in a direction of a through a driving shaft 171 to be slipped out of a storing concave parts 15, 16 of jigs 12, 13 and to be located between jigs 12, 13; then, jigs 12, 13 are tightly pressed against the inside furface of a pipe 11. Under this condition, a punch penetrates into a concave part 14 of jigs 12, 13 in an arrow direction to perform press. Next, the core bar 17 resumes between concave part 15, 16, and a pipe 11 is easily taken out from jigs 12, 13. Jigs 12, 13 are controlled in their location against the core bar by a guide 172 integrated with the core bar 17 when the core bar 17 is located in concave parts 15, 16.
