Pneumatic Sheet Metal Cutting and Bending Machine 

Abstract

Use of aluminum is increased now days in many industries like automobile, packaging, medical etc. The reason behind this is that the aluminum made things are quiet easier to manufacture, handle and reliable to use. So the aluminum goods manufacturing industries are striving hard to produce good quality products at large scale and cheaper cost. Hydraulically operated machines are too costlier for small scale and medium scale industries. This paper deals with pneumatically operated cutting and bending machine. The bending machine is one of the most important machine tool in sheet metal work shop. It is primarily designed for bending. The bend has been made with the help of punch which exerts large force on the work clamped on the die. The sheet metal cutting process is a main part of the all industries. Normally the sheet metal cutting machine is manually hand operated one for medium and small scale industries. Automation in the modern world is inevitable. Any automatic machine aimed at the economical use of man, machine, and material worth the most. In our project is solenoid valve and control timing unit is used for automation. The sheet metal cutting machine works with the help of pneumatic double acting cylinder. The piston is connected to the moving cutting tool. It is used to cut the small size of the sheet metal. The machine is portable in size, so easy transportable. The bending machine is designed in such a way that, it works when implemented is believed to result in reduced cycle time, costs and improved product quality. Other possible advantages are repeatability, increased productivity, reduced labor and integration of business systems. The manually operated machine is converted into pneumatically operated machine by applying proper design procedure. At the end of task, the conclusion is made and several recommendations are suggests to make an improvement about the result and the project for future study.

WORKING PRINCIPLE

The sheet metal cutting and bending machine works with the help of pneumatic double acting cylinder. The piston is connected to the moving cutting tool. It is used to cut and bend the small size of the sheet metal. The machine is portable in size, so easy transportable. The compressed air from the compressor is used as the force medium for this operation. There are pneumatic double acting cylinders solenoid valves, flow control valve and the timer unit is used. The arm from the compressor enters to the flow control valve. The controlled air from the flow control valve enters to the solenoid valve. The function of solenoid valves all of air correct time interval. The 5/2 solenoid valve is used. In one position air enters to the cylinder and pushes the piston so that the cutting stroke is obtained. The next position air enters to the other side of cylinder and pusses the piston return back, so that the releasing stroke is obtained. The speed of the cutting and releasing stroke is varied by the timer control unit circuit. Next the same procedure repeats to bending machine operation.

ADVANTAGES

  • The pneumatic is more efficient in the technical field.
  • Quick response is achieved
  • Simple in construction
  • Easy maintenance and repair
  • Cost of unit is very less
