Abstract

The finite element method has been used to determine the drawing of the details of the shape of the initial blank for compression and to establish the parameters of cold warping of such a high-carbon steel blade to obtain a hollow product with a variable wall thickness. By calculation, the shape and size of the initial workpiece have been determined. It has been shown that the use of a cold form of compression of the matrix of the traditional form does not allow the product of the desired form to be obtained due to the great strain and thickening of the walls in the bottom part of the deformed workpiece. Application of a matrix of a special profile, in which the deformation surface is formed by intersecting troughs with the same diameter of the cross section and consistently arranged with the same step, has reduced the effect of frictional forces, reduce the force of compression and the formation of a hollow product with a wall of variable thickness. Efforts and deformation work, distribution of specific forces on contact surfaces are established. The stressed-deformed state of the metal, the final form and the size of the product are determined. By the distribution of the intensity of deformations, the prediction of mechanical properties of deformed metal is carried out.
