Modelling and simulation of stepper feeder mechanism for punch press

Abstract

A common method of feeding the stock material into the press is bypassing it through a pair of feed rollers which apply friction to the material and rotate in a cooperative manner to feed the stock in to the punch press. By synchronizing the rotation of the feed rollers to the speed of the press,the stock material is fed in to the punch press at the proper rate.Stepping motors are widely used in robotics and in the numerical control of machine tools to perform high precision positioning operations.The principal object of this invention is to provide a strip stock feeding mechanism that is suitable for feeding any desired length of stock for each cycle and which may be very easily adjusted for various lengths of feed.It was found that cost of stepper feeder is quite less as compared to other types of feeder available in the market.
