Design and Fabrication of Bending with Twisting and Cutting Machine

Mechanical Engineering

Bending machine is used to bend a metal sheet, plate, rod and pipe. The aim of this project is to develop a metal bending machine. This machine is used to bend sheets into curve and the other curvature shapes and twist the plate. Circular ring are made manually, which suffers from many drawbacks like lack of accuracy, low productivity and resulting into severe fatigue in the operator. There are two different machines available in market for bending of bar, pipe and twisting of plate. There is no single machine available which bends sheet as well as pipe in a single unit and also twist plate. We develop a machine which performs bending and twisting operation on single machine. It reduces human effort and also required low less skill to operate this machine. We are designing bending with twisting machine with use of roller, motor, gear& support (frame). There are 3 roller used in bending machine. We are arrange separate attachment of die is provided, for twisting. During the roll bending process the sheet or plate or pipe is passed through consecutive rollers that gradually apply pressure on pipe. Because of this pressure the change in radius of pipe or sheet occurs.
