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.
