Abstract
PURPOSE: To bend tubing into a desired radius of curvature uniformly as well as greatly suppress an ovality formation phenomenon of section at the time of bending by pushing toward cradle the tubing at almost symmetrical plural positions on both sides to be supported, except for the central portion between the parts of tubing to be supported.
CONSTITUTION: Accordng to the predetermined carvature radius of the tubing P, each set bolt ll...is loosended and the position to which the tubing P is to be made contact is adjusted by moving the push heads 31, 31, 32, and 32 right and left and before and behind while keeping their mutual symmetrical relations through the slider 8... Then, the oil pressure cylinder 5 is operated to advance the push base 3 and the inside heads 31 and 31 are first contacted with the tubing P at the symmetrical position on both right and left sides of the tubing P. According to the curvature of the tubing P with advancing the base 3, the tubing P is bent by pushing while rotating it around the pin 9 and also keeping its facial contact with the tubing P. Then, the heads 32 and 32 are likewise made contact with the tubing P and then bent to finish bending processing by receiving the outside of tubing P curved at the final processing stage at the receiving head 4a of the receiving base 4.
