Abstract
1. Способ пластического структурообразования длинномерных заготовок, при котором осуществляют знакопеременную деформацию в пересекающихся каналах, путем образования очага деформации заготовки за счет смещения осей симметрии каналов, с одновременным одноосным растяжением, отличающийся тем, что в каждом участке заготовки последовательно создают очаги деформации сдвига в нескольких пересекающихся плоскостях. ! 2. Способ по п.1, отличающийся тем, что силу растяжения устанавливают из условия ! σ∂≤[σ], ! где σ∂, [σ] - соответственно действующие и допускаемые растягивающие напряжения в послеочаговой зоне заготовки, МПа. !3. Устройство для пластического структурообразования длинномерных заготовок, содержащее корпус с набором матриц, имеющих каналы, один из которых является входным, отличающееся тем, что матрицы имеют форму дисков одинакового диаметра с эксцентрично расположенными каналами, имеющими параллельные оси, с помещенными между ними кольцеобразными проставками, толщина которых определяется зависимостью ! , ! где Е' - эксцентриситет смежных пластин, мм; α - меньший из накрестлежащих углов между осями пересекающихся каналов, град. 1. The method of plastic structure formation of long workpieces, in which alternating deformation is carried out in intersecting channels, by forming a workpiece deformation zone by displacing the symmetry axes of the channels, with simultaneous uniaxial tension, characterized in that shear deformation centers are created in several intersecting sections in several intersecting successively in each intersection planes. ! 2. The method according to claim 1, characterized in that the tensile force is set from the condition! σ∂≤ [σ],! where σ∂, [σ] are the corresponding and admissible tensile stresses in the post-focal zone of the workpiece, MPa. ! 3. A device for the plastic structuring of long workpieces, comprising a housing with a set of matrices having channels, one of which is an input one, characterized in that the matrices are in the form of disks of the same diameter with eccentrically arranged channels having parallel axes, with ring-shaped spacers placed between them, whose thickness determined by addiction! ! where E 'is the eccentricity of adjacent plates, mm; α - the smaller of the right angles between the axes of the intersecting channels, deg.
