FABRICATION OF SENSOR OPERATED PNEUMATIC AUTOMATIC PUNCHING MACHINE

FABRICATION OF  PNEUMATIC AUTOMATIC PUNCHING MACHINE

SYNOPSIS
The pneumatic has gained a large amount of importance in last few decades. This importance is due to its accuracy and cost. The pneumatic punching machine has an advantage of working in low pressure. The press is the punching machine tool designed to punch by applying mechanical force or pressure. The metal is punched to the desired requirement.  The compressed air from the compressor is control by the Microcontroller to switch on the pneumatic system. After a few seconds delay the controller will off the compressor, so that the pneumatic cylinder moves upwards, the materials are kept between the punch and work table. Now the material is fed and the next stroke of the pneumatic is made ready.  When the material is correctly positioned then this machine is again actuated.

WORKING PRINCIPLE

A punch or a punching machine is a tool used to work metal (typically steel) by changing its shape and internal structure. A forge press reforms the work piece into a three dimensional object not only changing its visible shape but also the internal structure of the material. A stronger part results from this process than the object was machined. Bending is a typical operation performed and occurs by a machine pressing, or applying direct pressure, to the material and forcing it to change shape. A press brake is a typical machine for this operation.

The metal is placed between the plates, and the plates are pressed up against each other, deforming the metal in the desired fashion. This may be coining or embossing or forming. A punch press is used for forming holes. Progressive stamping is a manufacturing method that can encompass punching, coining, bending and several ways of modifying the metal, combined with an automatic feeding system. An object sensor is kept on the table which senses the work piece and sends corresponding signal to the microcontroller. According to the signal from the object sensor the microcontroller switches on / off the pneumatic system. Hence this system is an automatic one.
