Abstract
Tube bending is the metal forming processes used to permanently form pipes or tubing. One has to differentiate between form-bound(secure with a cover of bending) and freeform-bending procedures, as well as between supported and cold forming procedures. Form bound bending procedures like “press bending” or “rotary draw bending” are used to form the work piece into the shape of a die. Straight tube stock can be formed using a bending machine to create a variety of single or multiple bends and to shape the piece into the desired form. This process can be used to form complex shapes out of different types of ductile metal tubing. Freeform-bending processes, like three-roll-push bending, shape the workpiece kinematically, thus the bending contour is not dependent on the tool geometry. The main goal of this project is composition of deformation in tube or pipe bending theory and the effects of Rotary Tube bending machine parts including; clamp die, bend die and supporter die to obtain optimum bending requirements. "Rotary draw tube(pipe) bending is presented alongside machinery parts with their function and effects on bending moment and failure types along with their reasons”. Deformation of tubes can be achieved in numerous ways. One of the most useful type is rotary tube bending machines which is used in many industries such as aerospace, automotive, HVAC systems and so on. It is important that all components of system should mate properly after producing and because of this bend shaping requires sensitive operation on each component to ensure regularity of production processes with high quality end-product. However it brings some troubleshooting like wrinkling, springback, breakage and validation. This failure depends on geometry of the material such as bending radius, tube thickness and also friction factor between dies and the tube. Effects of all parameters should be examined before generating the theory for a best solution. Therefore, prediction of the required moment for the proper bending process with low cost and shortened production time is needed. Pinion gears, spur gear teeth, solved using radioss solver, rotational force analysis is solved using radioss and moment is applied for complet
