Abstract
PURPOSE: To surelay prevent an excessively large plastic deformation velocity to be caused at a part of a pipe undergoing a tensile tress due to a bending work, by making a forced movement of a press die of a rotary drawing type pipe bender in the drawing direction synchronize with a pipe bending action.
CONSTITUTION: A clamping die 50 is separated from a clamping die 22 and a press die 74 is separated from a blank holding die 78; a blank pipe P is set at a prescribed position; then, the dies 50, 74 are moved to the illustrated right side for pressing and clamping the blank pipe P. If a rotary frame 12 is a required angle turned around a line 14 in the direction C, the blank pipe P, being clamped at each clamping position of dies 22, 50 and 74, 78, is bent around a bending die 16. hereupon, since the dies 16, 74 are connected to each other through a subsidiary member 84, a bracket 90 and a connecting member 94, the die 16 rotates together with the frame 12, and at the same time, the die 74 is drawn by the die 16 through the member 94. Then, the die 74 is guided by a roller 70 and slides along the outer surface of the balnk pipe P; at the same time, the die 74 is forcibly moved axially foward and advances toward the die 78.
