Abstract

PURPOSE: To simultaneously bend a pipe at one or several positions and prevent its buckling and flattening by pressing the pipe by means of rotatable dies in combination with punches.
CONSTITUTION: A pipe P is set on the right and left grooved dies 2, 2 of a lower shoe 1 and the grooved auxiliary dies 7, 7 which are held horizontally by means of the pads 11 on an elastic material 12. Next, an upper shoe 14 is lowered and a grooved punch 15 of a semicircular shape abuts on the pipe P. At this time the auxiliary die holder 9 supported by a cushion rod 6 does not descend and the auxiliary dies 7, 7 rotate against the elastic material, whereby the part near the center of the pipe is bent. Further, the shoe 14 lowers and while the pipe P is being held by the semicircular punch 15 and the auxiliary dies 7, 7, the rod 6 is lowered until it allows to contact with the rotary punches 16, 16, thus the working progresses from the central part of the pipe P toward the outside. Further, the shoe 14 lowers and knock-out punches 21, 21 also restrain the pipe P by the reaction force of a spring 20, whereby the bending is accomplished.
