Abstract

PURPOSE: To make pollible the bending work for the pipe to be performed in a short time at good workability, by simultaneously performing the bending work for specified plural positions in the pipe previously cut into a specified length, using specified die and wing.
CONSTITUTION: The pipe 1 is previously cut into a specified length, and is inserted into the space between the die 6 and the wing 7 of each head 41, 42, 43 and 44, which are waiting keeping a specified interval; after that, the hydraulic cylinder 13 is actuated for moving the wing base 12 toward the die 6; hereby, the pipe 1 is caught between the die 6 and the wing 7. Next, each hydraulic pulse cylinder 9 of each head 41W44 is actuated so as to insert the cam 8 at a specified speed into the space between a pair of wings 7 which are then swung along the curved surface of the die 6; hereby, the pipe 1 is bent and also the die 6 is moved by the pulse motors 17 and 22 in the direction perpendicular to the axis of the pipe 1, so as to follow up the bending condition of the pipe 1.
