Project Abstract

Abstract
The project focuses on the design, development, and testing of a bench shearing machine for use in metal fabrication workshops. The aim of this research is to address the need for a reliable and efficient shearing machine that can accurately cut various materials such as metal sheets, rods, and tubes. The machine is designed to be compact, easy to operate, and safe for the user. The constitution of the bench shearing machine includes a sturdy frame, a cutting blade mechanism, a clamping system, and a leverage system for applying force to make the cuts. The frame is constructed using high-quality materials to ensure stability and durability during operation. The cutting blade mechanism is designed to provide clean and precise cuts on different materials with varying thicknesses. Fabrication of the bench shearing machine involves the assembly of the frame, installation of the cutting blade, and integration of the clamping and leverage systems. Careful attention is paid to the alignment and calibration of the components to ensure optimal performance. The machine is also equipped with safety features such as blade guards and emergency stop buttons to prevent accidents in the workshop. The testing phase of the project involves evaluating the performance of the bench shearing machine in cutting various materials. The machine is tested for its cutting capacity, accuracy, and repeatability. The results of the tests are used to make any necessary adjustments to the machine design to improve its efficiency and reliability. Overall, the constitution and fabrication of the bench shearing machine are crucial steps in providing metal fabrication workshops with a reliable tool for cutting materials with precision and accuracy. The project contributes to the advancement of manufacturing technology by introducing a cost-effective solution for small-scale metal cutting operations. Keywords bench shearing machine, metal fabrication, cutting blade mechanism, clamping system, leverage system.

Project Overview

INTRODUCTION

Later in the years Nigeria as a country failed to react to the rapid advancement in technology until 1986, she realized that in both economy and technology she was under developed, she was dependent on the developed countries for survival, because many thing are being important from those countries. Attempt made to solve these problem include, introduction of the structural adjustment programme (SAP) and the war against indiscipline and corruption (WACI). These bodies prohibited the importation of some goods, there by building the inspiration on our people to embrace indigenous technology. This led to significant achievement in the field of technology of this country.
Since this great achievement has made engineer, scientist and technologist in this country were able to join efforts both mentally and manually into production and research programmes. One of the fruits of their contributed effort was the invention of the bench shearing machine.
The bench shearing machine is manually operated, it can be useful in work shops or factories.
In fact this product is aimed at providing a close substitute to the famous Japan made bench shearing machine.
It is worthy to note that this bench shearing machine is designed and fabricated using our locally available materials to show the important of copy technology.
PURPOSE OF THE PROJECT
The fabrication of bench shearing machine is to reduce, alleviate and to eliminate suffering, time, money, energy, and waste of material and more especially the need for technological break through and self reliance which has been major concern of the federal government.
Right from time immemorial metal shearing has been a very great problem in the society.
To help eradicate this problem this project write up has delved into simplicities and construction of bench shearing machine that can be use to cut up to 4mm sheet of mild steel plate with a treated blade made up of high carbon steel.
The machine is manually operated with handle known as the effort, the longer length of handle helps it to increase its output towards the work piece the material example mild steel, dead mild steel or aluminum alloys.
