ABSTRACT

• The bending machine is one of the most important machine tool in sheet metal work shop. The bend has been made with the help of punch which exerts large force on the work clamped on the die.

• The automation strategy results in reduced cycle time, costs and improved product quality, increased productivity, reduced labor and integration of business systems.

• Automation is achieved with the help of pneumatic system.

INTRODUCTION

• Now a days in industries especially in automobile and other industries the bending machines are widely used. Earlier the bending machines where operated manually. So the output of machine was very less.

• Now the technique of bending operation of the component is changed. the output of machine was very high.

• The main aim of this project the manually operated press can be converted into a semi or fully automatic machine.

• In this project the loading and unloading of the component is done manually and the bending of the plate is done automatically.

I)When the manual switch is not operated, the spring will restore the valve to its original position.

ii) From the position of the spring, one can deduce that the block is operating. The other block will not operate until the switch is pushed.

iii) Air pressure exists along this line because it is connected to the source of compressed air.

iv) As this cylinder cavity and piston rod are under the influence of pressure, the piston rod is in its restored position.

v) The rear cylinder cavity and this line are connected to the exhaust, where air is released.

ADVANTAGES

• Simple in Design and easy to Control. • Pneumatic systems require very little

maintenance.• Compressed Gas can be stored, allowing the

use of machines when electrical power is lost.• Very low chance of fire (compared to

hydraulic oil).• Machines can be designed to be overload safe.

APPLICATIONS

• Automotive industries.• the petroleum industry.• the construction of high pressure storage

vessels.• Casing for concrete pilings used in

construction projects.• Delivery of fluids, either gaseous or liquid,

in a process plants.
