Abstract

This paper presents the design result for the development of a motorized sheet metal rolling machine. The aim of the research is to design a rolling machine that can roll metal sheets of up to 3 mm thickness. Sheet metal rolling is a process of converting a sheet of metal into a complete hollow cylinder. The machine consists of three rollers; slip roll, pinch roll and a back roll. The rollers are made of mild steel shaft 1500 mm long and 90 mm in diameter. The whole system is mounted on a metal frame made from mild steel plate also. The sheet metal is fed continuously between the upper and lower roller. The upper roller is an adjustable roller which slides in an upward and downward direction normal to the roller. The bending stress using analytical method is 545.45 Nmm^-2 with deflection of 909.46 mm. A load of 1753.25 N is required to bend a mild steel sheet metal of 3 mm.
