Design of Multi Bend Radius Bending Die for CNC Tube Bending Machine

Sachin Kamble

Abstract: Tube bending and pipe bending services produce finished parts from tubes and pipes. Plastic deformation of tubes can be achieved in numerous ways. One of the most useful types is CNC tube bending machines which is used in many industries such as aerospace, automotive, HVAC systems and so on. Bending die on the numerically controlled (NC) tube benders or other benders can bend tubes with only one kind of bend radius formed on the die. It is difficult for such a situation to meet the requirement of modern manufacturing with characters of much varieties and small batch. In present CNC tube bending machines the only one die used for forming same bend radius for product. It slower the production rate and increase requirement of the trained manpower. The present study proposed a new concept of rotary draw bending die called Multi bend radius bending die, on which tubes with different bend radius within a definite range can be bent using the same die by only adjusting the Diameter of bend die.
