Design and Fabrication of a Three - Rolls Plate Bending Machine

Abstract

This paper is aimed at designing and fabricating a low cost motorized 3-rolls plate bending machine to bend a metal plate up to 6 mm thick mild steel plates. The major components of the machine design for are: the rolls shaft diameters; thee chain drive; the spur gears drive and holding keys and the framework. Materials were selected to meet the machine requirements of strength, machine accuracy and reliability. The machine components were constructed by the various machining processes of cutting, turning and milling, and were thereafter arranged and joined together by appropriate joining methods such as welding and screw joints. The fabricated motorized 3-rolls plate bending machine with a 10hp electric motor is quite effective and efficient with maximum thickness of 6mm mild steel plate. The total cost of production is $1,363.64 which is relatively cheap compared to equivalent available in the market.

Keywords: Bending parameters, chain drive, keys, roll-bending, roll- shaft, spur gears drive.
