【 摘 要 】

An experimental study of the developed new technologies for obtaining large-sized parts with an elliptical surface has been carried out. The advantages and disadvantages are established, as well as the boundaries of effective applicability of new combined process. Verification of the results of computer simulation based on testing the technology in the conditions of a laboratory rolling mill was performed. Optimal geometric shapes of matrices and punches to produce spherical and elliptical bottoms of various thicknesses and diameters are obtained on a thick plate rolling mill. The methods of correction of the technology for obtaining large-sized parts with an elliptical surface have been developed and tested in laboratory conditions to eliminate the identified shortcomings.
