Borys R. Drawing with thinning bimetallic tubular elements of dissimilar metals and alloys

The actual scientific and practical task of improving the efficiency of manufacturing bimetallic tubular elements in engineering industries through the development and support of the process of drawing sheet thinning dissimilar metals and alloys. Analytical and numerical calculation process compatible with thinning pulling two dissimilar metals with heating. The relation between the parameters of the stress-strain state at the boundary surface and the degree of strain thinning layers with the original geometry of the workpiece, the mechanical properties of the individual layers and the geometry of the working surface of the matrix. We observe that the error calculation does not exceed 7 ... 14%. Based on the generalization of theoretical and experimental results obtained in the thesis the block diagram (algorithm) calculation of technological process parameters extraction bilayer with blanks thinning is proposed promising new technical solutions and implemented technological advice needed for the manufacturing process BTE. The results are implemented at industrial enterprises.
