Abstract:   (2013 Views)
Copper clad aluminum composite wire used in wire and cable industry is an applied product. This product must be manufactured according to standard ASTM B566. According to this standard the connection between the layers is one of the quality parameters. Interlayer pressure during the production process, plays an important role in the quality of connection between two layers. The effects of important wire drawing parameters, including a half-angle dies, reduction ratio and coefficient of friction on the interlayer pressure were discussed by slab methods. After samples making, test of wire drawing process was conducted to determine the force with three modes of dry friction, oil lubrication and grease lubrication. There was good agreement between experimental and analytical methods. With Increase in friction coefficient of interlayer the interlayer pressure will increase. With increase in half angle of die, the interlayer pressure was increase significantly. So that, by increasing the half angle of die from 5 to 75 degree, the interlayer pressure increases about 3 times. Also, with increase in reduction of area the interlayer pressure was increase. But, it was found that the friction coefficient of die does not have a role in interlayer pressure changes.
