The various elements of a die are die block, die holder, punch, punch holder, stripper, stock stops and knockouts. We will here consider the design of all these individual elements and from is design for compound, combination and progressive die could also be carried out. i. Die Block Design: Overall dimensions of the die block are determined by the minimum [...]
In design of cutting dies, the cutting pressure coming on it is very important and its magnitude is of the offer of 1.5 L x t x fs . where L = periphery of work piece, t = thickness of work piece, fs = ultimate shear strength of work piece. In addition, total cutting force depends upon: (i) Sharpness of [...]
In simple die, the dies are designed to perform only one operation. But, by proper design of the dies, it is possible to carry out several operations in one stroke of the ram. The dies of the first type are known as single operation dies and second type are known as multi-operation dies. The single operation dies could be further [...]
