Design and Analysis of Multiple Radius Pipe Bending Machine.

In this work a low cost and easy to manufacture multiple radius pipe bending machine is designed to bend a given diameter conduit pipe in a required bending radius. In most of the industries, pipe bending is a salient requirement. In market there are different types of pipe bending machines available. But most of them can bend only a particular diameter pipe into a specified bending radius. To bend into different bending radius the die and other related parts need to be changed. Even some pipe bending machines are available to bend a particular diameter pipe into any bending radius but either they are very expensive or difficult to manufacture. So this project is to design a machine to satisfy our requirement. The working of this machine is simple and also the cost of manufacturing is comparatively cheaper than what is available in the current market. This machine can bend a pipe up to 32mm diameter to a minimum bending radius of 150mm. The material of the machine used is mild steel and hydraulics with piston-cylinder is used as power source. Static analysis of different parts is also carried out in ANSYS and finally a prototype is fabricated in order to test the machine and it is successful by all means. [ABSTRACT FROM AUTHOR]
