MULTI-OPERATIONAL ELECTROMAGNETIC FORMING MACHINE

ABSTRACT The purpose of this project is to design and fabricate the economic machine for small sized sheet metal products. Conventionally for production of these products large machines are used which are not cost economical. Also there is a loss of energy due to friction. The objective of this project is to reduce the energy consumption, cost and to perform the various forming operations on a single machine. The solution is obtained with the implementation of ‘Electromagnet’. Since the actuation is electrically assisted the operation is frictionless and accurate. The punching force is controlled by varying current using ‘DIMMER’ circuit. The power is consumed only during the punching stroke resulting into efficient operation. After successful fabrication, the set up was tested and optical testing is done for any defects in the punched samples.
