Design and fabrication of three roll bending machine

Abstract

In present time, the motorized 3 roll bending machine is universal forming equipment for sheet plate into cylinder and curved sheet. It is widely used boiler, shipbuilding, petroleum, chemical, metal structure and machinery manufacturing industries. The aim of this project is to design a new motorized 3 roll sheet bending machine for industry, having latest feature like lowering top roll by single lever mechanism and providing input motion to both the lower roller to avoid the problem of slippage. The existing 3 roll sheet metal bending machine of industry is totally hand operated. The existing machine has many problem like slippage, accuracy and time required to make one cylinder is more than motorized machine. The demand of hand operated 3 roll sheet metal bending machine is low, so in order to survive the competition of market industry has given a task to make a motorized 3 roll bending machine.
