Abstract
1. Способ изготовления тонкостенных оболочек сложной формы из нержавеющих жаропрочных сталей и сплавов с сопряжениями сложного профиля путем многопереходной давильной обработки листовой заготовки при продольном перемещении давильного инструмента, установленного с зазором относительно последней, отличающийся тем, что формообразование проводят одновременно двумя давильными роликами, черновым и чистовым, причем черновой ролик настраивается с опережением движения относительно чистового, а траектории движения роликов, исключающие разнотолщинность оболочки за пределами допуска при формообразовании сложного профиля, задают отдельно для каждого ролика управляющей программой для раскатного стана с учетом температурных деформаций от нагрева оправы на предыдущем переходе.2. Способ по п.1, отличающийся тем, что для стабилизации процесса вытяжки и исключения перенаклепа поверхности зазоры для чистовых роликов выбирают в пределах 0,35-0,6 от величины зазора для черновых роликов.3. Способ по п.1, отличающийся тем, что корректировку температурных деформаций от нагрева оправы по мере формообразования оболочек в пределах одной партии, проводят, начиная с третьей детали в партии на каждом переходе.1. A method of manufacturing thin-walled shells of complex shape from heat-resistant stainless steels and alloys with mates of a complex profile by multi-junction pressing processing of a sheet billet with longitudinal movement of a pressing tool installed with a gap relative to the latter, characterized in that the forming is carried out simultaneously by two pressure rollers, rough and finishing moreover, the draft roller is set ahead of the movement relative to the finishing one, and the trajectories of the rollers excluding times the thickness of the shell outside the tolerance during the formation of a complex profile is set separately for each roller by the control program for the rolling mill, taking into account temperature deformations from heating of the frame at the previous transition. 2. The method according to claim 1, characterized in that in order to stabilize the drawing process and eliminate re-riveting of the surface, the clearances for finishing rollers are selected within the range of 0.35-0.6 of the clearance for roughing rollers. The method according to claim 1, characterized in that the correction of temperature deformations from heating of the frame as the shells are formed within one batch is carried out starting from the third part in the batch at each transition.
