This document describes a project to design and manufacture a pneumatic shearing machine. A group of 4 mechanical engineering students will work on the project. The introduction discusses the need for new machines and techniques to increase production rates and manufacture quality products more cheaply. The working section explains how a pneumatic double acting piston and cylinder with a foot-operated directional control valve will move the shearing blade up and down. Diagrams show the basic design of the pneumatic shearing machine. The objectives are to potentially add a roller feeder, temperature sensors, a scrap collection system, and safety glass.

2. Introduction
An engineer is always focused towards challenges of bringing
ideas and concepts to the life. Therefore, sophisticated machines
and modern techniques have to be constantly developed and
implemented for economical manufacturing of products. At a same
time , we should also take care that there has been no
compromise with quality and accuracy. In the age of automation
machine became an integral part of human being. By use of
automation it is proved that it gives more production rate than
manual production rate. In competition market everyone wants to
increase production and make there machine multipurpose. New
machines and techniques are developed continuously to
manufacture various products at cheaper rates and high quality .
So we are going to make machine far “SHEET METAL
INDUSTRY” and should be used as circle cutting cum straight
cutting machine. The machine is simple to maintain and easy to
operate . So we tried for “PNEUMATIC SHEARING MACHINE”.
Shearing machine is one of the principal machine in sheet metal
industry. It is mainly used as the name indicates cut strips.

3. WORKING
 Here advancement of header is carried out in upward
and downward direction using pneumatic double acting
piston and cylinder unit arrangement along with the foot
operated direction control valve . In this type of machine
high pressure air is used as the working fluid for
transfer of power and the motion. To control the to and
fro motion of pneumatic cylinder , the air energy has to
be regulated, controlled, and reversed with a
predetermined sequence in pneumatic system. Similarly
one has to control the quantity of pressure and flow rate
to generate desired level of force and speed of
actuation .To achieve the functions , valves are used to
1)start and stop pneumatic energy 2)control the
direction of flow of compressed air 3)control the flow
rate of compressed air 4)control the pressure rating of
compressed air .
