Design and Analysisof Electromagnetic Punching Machine

Mechanical engineering

Punching Machine is one of the important machines in paper cutting industry and sheet metal industry. Electromagnetic punching machine is working on the principle of electromagnetics. It is used to cut card board, sheets, papers, foam, and thin plastic sheets. The machine are simple to maintain, easy to operate. The work piece is often in the form of a sheet or roll. The materials for work piece may vary, commonly being metals and plastics. The punch and die both have different shapes for creating an array of variety shaped holes in the workpiece. The multiple punches can be used together to create a part in one step. The greatest challenge faced is to overcome the energy wasted because of friction in any mechanical process. This paper introduces the basic construction of an electromagnetic punching machine to carry out the punching operation. After successful fabrication, the set up was tested and the punching force produced was validated.
