Abstract

Die-set for multi-purpose operations such as bending, trimming and punching, are usually complex in design and expensive. Past work on die design indicates that the misalignment of a die and punch caused by the deformation of the die-set directly influences the life of the die and punch. Consequently anything which enables accurate prediction of the magnitude of relative displacements of the die and punch can be of a great help to press-tool designers.

Earlier studies [1] on tool wear in blanking/punching assume that the normal pressure distribution on the bottom face of the tool is linear while recent work on finite element modelling of a die-set to analyse the die-deformations assumes that the point of location of a die-post (guide pin) on the die-set plate has no effect on the alignment of the die and punch.

The present 3-D finite element model for the die-set takes these contributing factors into account. The results obtained are checked against the practical data on die-set design and experiments. Some suggestions are made to improve radial stiffnesses of the die-set and thus alignment of the die and punch.
