Design and Development of a Cost-Effective Automated Metal Sheet Bending Machine

Abstract

In the metal production industry, metal sheet fabrication is crucial. This involves the manufacturing of products like hinges, tools, vehicles, and machine plates. A single flat sheet of metal can be folded into different shapes without being stretched or chopped. Numerous research studies have been carried out to design metal sheet bending machines using techniques ranging from manual, semi-scale metal, and metal product makes is a crucial job driven by the worldwide movement towards intermediate technology and sustainable development. Manual metal bending which is done with the aid of a vice and hammer requires the use of human effort which could result in accidents, man- hour loss, and a reduction in revenue. Hence, this research focuses on the development of a cost-effective automated metal sheet bending machine. This design comprises a microcontroller, display, power supply, roller bending components, rigid metallic frame, relays, transistors, actuators, and other discrete electronic components. The device is aimed at effortlessly bending aluminum sheet that is 0.5 to 0.7mm thick with the elimination of extensive human effort, and time wastage, and also ensuring safety. The results of the performance evaluation carried out on the developed bending machine show a reduced cycle time, an increase in productivity, manpower reduction,

and an increase in the safety of the operator which has the potential of increasing the revenue of metal sheet bending operators.
