Abstract
The operation of obtaining cylindrical products with a titling pad made of titanium alloy VT6 is viewed in the article. The operation involves impacting a bar blank made of titanium alloy VT6 with the use of a punch having sloped edge. When obtaining parts having titling pad made of difficult-to-form alloys, it is necessary to formulate the modes of technology. It is required to specify the rates of deformation and the impact of contact friction on the kinematics of the material flow and the force of shape change to assess the capabilities of the process performed by CAE modeling. Therefore, the simulation of obtaining cylindrical products with a titling pad made of titanium alloy VT6 was performed in the DEFORM modeling program. The influence of the speed conditions of the operation on the change in the values of stress intensities in the product was found. The dependences of the influence of the angles and rates of deformation on the landing force are revealed. The results of theoretical studies obtained during the simulation were summarized. A regression analysis of the results obtained during the simulation was performed. Based on the simulation results, expressions for estimating the intensity of stresses are obtained. The results of regression modeling are in good agreement with the results of computer modeling. Using quantitative modeling results, a regression assessment of the force was taken. Regression equations in natural values are obtained for the assessment of the impact of key process parameters during setup, which can be useful directly when assigning technological modes of titanium alloy blanks setup. The results can be used in the implementation of manufacturing technologies for parts with flange seals, characterized by the best strength characteristics and good load resistance.
