The most effective scheme for achieving high degrees of deformation of the workpiece, which allows efficient use of press capacity and perform deep deformation step without replacing shaped slotted mandrel. To implement the scheme developed technological equipment. . 2. Defined tool materials for the manufacture of specialized slotted opravok, deforming matrices and clips. 3. Developed and manufactured involute profile cutters for cutting slotted grooves on the mandrel. Designed diamond profiling wheels for carbide cutters and kubonitovi wheels for grinding surfaces on the slotted mandrel. Made slotted mandrel reduction sleeves for improved accuracy. Made of external deforming tool kit, which consists of three matrix. 4. The optimal size reduction in axial force criterion occupancy profile mandrel. Reducing axial force reduction without loss of quality can be achieved by increasing the cycles of deformation and redistribution of tension on the dies. This will increase tool life period, but will increase its value and significantly increase the complexity of the process of reduction. 5. Based on the results improved design tool and optimize its geometry is made. 6. studied mode of deformation during the formation of internal surfaces slotted sleeve by reduction. Established picture of the intensity distribution of strains and stresses in the splined sleeves profiles reduced vowels. 7. Features of use of technological lubricants, due to the peculiarities of the technological scheme of reduction. Based on established technology developed technological process of restoring splined connection driveshafts diesel trains D-1. Lifetime restored this process cardan shafts due to strain hardening contact surfaces splined connection increased 1.4 times. Conducted testing of the technology developed in terms ISH and made its revision. The production of the restoration of cardan shafts diesel trains D-1 ISH manufacturing base. The recovered pilot batch of four cardan shafts diesel trains D-1. Product Description popup.authors Мельниченко Володимир васильович Студенець Сергій Федорович popup.nrat_date 2020-04-02 Close
