Влияние особенностей конструкции рабочей поверхности матрицы оснастки на параметры процесса вытяжки с утонением биметаллических трубчатых элементов

Abstract

Theoretical and experimental study of influence of design features of the working surface of the matrix snap on the parameters of the drawing process with thinning of bimetallic tubular elements. In the finite-element modeling of the drawing process with thinning determined the stress strain state of the deformation and stress of the process with different coefficients of friction and the cone angle of the working part of the matrix. Experiments demonstrate the effectiveness of formation of the compound in the interaction of the layers in the combined matrix.
