ABSTRACT:
A telescoping die for use in place of a conventional fixed die in a multi-axis tube bender. The telescoping die provides a means of automatically varying the distance to the moveable die thereby increasing the range of possible bend radii that can be formed while maintaining a close positioning between the feed mechanism and the telescoping die.
