Three dimensional computer aided design of the numerically controlled pipe bending machine

The working principle of the pipe bending machine is introduced briefly.The PRO/E software is adopted to design the mechanical structure of the STAR-03W numerically controlled pipe bending machine.Discussed in detail are the calculation method of the pipe bending moment,design of the bending axis and bending arm,design of the combined mechanism along Y and B axes,design of the adjusting devices and design of the tool bed.The choice of the materials of the key parts is also discussed.In order to investigate the rationality of the designed structure of the numerically controlled pipe bending machine and control its action process more accurately,simulation of the mechanical movement of the machine is carried out.The numerically controlled pipe bending machine can be widely applied to bending various tubes and pipes in many industries,such as the automobile and air-conditioner industries.
