Push Bending

A style of bending where the bend arm is moved positive a few degrees, then the tube is pushed through a set of rollers. This achieves a large radius bend.

Typically, there is a single smaller roller on the clamp die. That roller opposes a larger roller that is placed where the bend die in rotary draw bending is normally placed. Two rollers of the same CLR as the front clamp roller are on the pressure die assembly. All four rollers rotate freely. The tube is pushed through these rollers to create a large radius bend.
