pneumatic sheet metal cutting machine

SYNOPSIS:

The objective of the project is to prepare a machine that cuts sheet metal without human efforts but operates pneumatically (move or worked by air pressure).

Compressed air is used as working media. The compressed air moves the blades of the machine to cut the sheet of metal.

     The idea of the project is generated due to a manual sheet shearing machine in the workshop of our college. In that machine sheet metal is placed in between the two shearing blades of the machine and the lever is pulled down to move the upper movable blade and cut the workpiece.

  

                   But in that machine large force is required which can make tire to a worker who continuously works on it for mass production in large-scale industry. So, to reduce the human efforts pneumatic machine should choose.

Hence for some development of the machine, We have chosen this subject for our project. We hope that a good idea will develop and we can use it in many industries in the surrounding and our practical knowledge will be improved.

Pneumatically operated:

Here the advancement of the header is carried out in the upward and the downward direction using the 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 the transfer of power and motion.

Working:

Initially, the air compressor is started and allowed the receiver tank air pressure to reach up to 8 bars. The supply of air is then passed to the manifold through the FRL unit(Filter, Regulator, Lubricator) to condition the air and is eligible for industrial use.

From the manifold, a separate supply for the machine is taken out and given to the ON-OFF switch, To operate the machine at will without interrupting the running of the compressor.

Then the pipe carries compressed air first to the machine direction control valve.
