Influence of technological conditions of drawing on inhomogeneity of deformation under condition of hydrodynamic lubrication
Original language description
At conventional lubrication during wire drawing it is possible to expect the value of the friction coefficient between 0.05 and 0.13. However, according to some authors it is possible to achieve under conditions of hydrodynamic lubrication (for example with use of compressive dies) a friction coefficient ? = 0.0005, it means hundred times lower. Such values already allow us to consider such technological parameters, which would lead at higher friction coefficients to unacceptably large total forces, orto wire breakage. We focus in this paper on the FEM analysis of drawing with small deformation angles of the die and large partial deformations. We will focus on normal cone die. The first part presents a simulation of drawing with use of small deformation angles, for friction value ? = 0.0005. We analyse the influence of the die geometry on the overall drawing force and the inhomogeneity of deformation intensity over the cross section of wire at single pass drawing.
