Automatic Punching Machine using Geneva Mechanism

DESIGN OF GENEVA WHEEL BASED AUTO-ROLL PUNCHING MACHINE
Abstract - On the conventional punching machine the time for job setting, marking, punching operation is more. Labor cost is also more. With Geneva based punching machine the time for job setting, marking, punching, labor cost decreases and also less maintenance cost. In this project we are designing and fabricating the prototype of Auto roll punching machine using Geneva mechanism. This project is specially designed for automatic punching in metal sheet. This project is to introduce automation in industries. The major components involved in this project are dc motor, cam arrangement, chain drive, Geneva mechanism and punching tool. In this project we are using two rollers for moving the sheet during operation. A dc motor is connected with cam. The cam has a pin which rotates the Geneva wheel. The Geneva wheel is attached to the chain drive. The other end of the chain drive is connected to the rollers which roll the metal sheet and the punching operation is done by the punch tool. It is suitable for making mass production of the sheet metal punching.
Working
When the motor is powered the cam drive disc is rotated. The linear rod which is attached to the cam drive disc with eccentricity from the center is reciprocated on the punching machine. The punching machine consists of a punch head, when the linear rod is moved down it presses the punch head. The punch head consists of punch tools which punches the paper in required manner.
The cam drive disc has a pin attached to it, which enters into the slot of the Geneva wheel and turns the Geneva wheel. For every one rotation of cam drive disc, the Geneva wheel rotates 1/4th of the rotation. The shaft of the Geneva wheel is attached to the sprocket wheel. When the Geneva wheel rotates, the sprocket wheel also rotates which in turn rotates the rollers attached to the other sprocket wheel. The two sprocket wheels are connected by a roller chain. With the help of rollers the paper moves forward and the punching operation is done on it.
