Modeling of Geometry Design in Wire Drawing Using Cassette Roller Die
The most important activity of wire drawing technology is the correct design of stages geometry. The wire drawing within a roller die is described by an irregular deformation on wire width, strongly connected by the gauge shape between the rollers and cross section wire surface. Free lateral wire surface that has no contact with the roller on the deformation zone obstructs the wire elongation. There is a biunique correspondence between the shape and dimension of wire that enters between the rollers, and the free space between the rollers, corresponding to a specific stage of drawing. This has a great effect on dimensional accuracy of final wire. A drawing zone feature based model, allowed the examination of interaction evolution between wire and rolls geometry. This analysis helps the user of this technology to make a proper change in the arrangement and position of wire entering between rolls, or in the rolls configuration.
