![]() ![]() Furthermore, in many cases, Ercolina standard off the shelf stock tooling is offered in many different centerline bend radii to accommodate your bending applications quickly. Ercolina rotary draw benders create aesthetically pleasing bends when the right tooling is matched to the application. Rotary draw benders are the most popular machines for use in bending tube, pipe and solids for applications like: handrails, handrail elbows, and wall returns, handicap handrail, furniture and sign frames, custom vehicle parts such as roll cages, brush bars, nerf bars, light racks, running boards and much more. This control helps to produce tube bends of superior quality. What distinguishes rotary draw bending from other methods is the line of tangency is fixed at the point of bend to fully control the flow of material. Contact area between the rotating bend die and the counter bend die is referred to as the line of tangency. The counter bend die or pressure die applies opposing force to the tube ensuring high bend quality. Specifically, the forward tangent of the pipe or tube is held in Ercolina’s gripper arm of the bend die as the pipe is drawn around and into the bending die groove. Bends are formed by drawing the material around a rotating bend die center former. Rotary draw bending is the principal method of high-quality tube bending today. Ercolina rotary draw tube and pipe bending machines are ideal for most bending applications. ![]()
