Abstract
Dies of high-pressure vessels (HPV) for the synthesis of superhard materials (SHM) are press-fitted into ring blocks with considerable interference to improve their stability. The mathematical statement of the problem of determining the stress-strain state (SSS) of the die and ring block during press fitting, which includes a computational scheme, and a system of equations for solving elastoplastic contact problems for large deformations, is presented. The SSS of the die and ring block is investigated on the basis of an FEM-based numeric method developed with allowance for the history of the press fit in accordance with existing and proposed procedures. Implementation of the new press-fitting technology has made it possible to improve the stability of dies and ring blocks by 30-44%.
