Abstract
A tube bending assembly adapted for use with a rotary draw bender, and preferably including a bend die mounting unit for securing a plurality of stacked bend dies drivenly coupled to the bender, a bend die tower unit for structurally supporting the bend die mounting unit, a wiper die mounting unit for securing a wiper die adjacent a selected bend die, a clamp die mounting unit for positioning and securing a clamp die, a pressure die mounting unit for securing a pressure die adjacent the clamp die, a mandrel saddle unit for positioning and enabling the utilization of a mandrel assembly, a collet saddle unit for positioning and enabling the utilization of a collet, and a bolster unit that interconnects the units, so as to present an integrated assembly capable of concurrent disconnection from and connection to the bender, and thereby reducing the tool set change-over period.
