Изобретение относитс  к области обработки металлов давлением.This invention relates to the field of metal forming.

Известен способ изготовлени  полых изделий С внутренним резьбовым профилем из волокнистых -материалов путем выт жки заготовКи пуансоно.м, имеющим на наружной поверхности резьбовые канавки.Known method of manufacturing hollow articles With an internal threaded profile made of fibrous materials by stretching billets with punches that have threaded grooves on the outer surface.

Однако известным способом невозможно получить качественный резьбовой профиль на издели х из металла из-за неравномерного распределени  металла по профилю резьбы и неполного заполнени  металлом резьбовых канавок на пуансоне.However, it is not possible in a known manner to obtain a high-quality threaded profile on metal products due to the uneven distribution of the metal along the thread profile and the incomplete filling of the threaded grooves on the punch with metal.

Описываемый способ позвол ет изготавливать полые издели  с качественным резьбовьш профилем из металлических заготовок за счет того, что выт жку заготовок осуществл ют с утонеНИем стенок, а после выт жки заготовку вместе с пуансоном обкатывают роликами .The described method makes it possible to manufacture hollow articles with a high-quality threading profile from metal blanks due to the fact that the blanks are stretched with wall thinning, and after stretching the blanks are rolled with rollers along with the punch.

Обкатка заготовки роликами облегчает также съем издели  с пуансона.Running the workpiece with rollers also makes it easy to remove the product from the punch.

Отписываемый способ осуществл ют следующим образом.The write-off method is carried out as follows.

После вырубки листовой заготовки и выт жки из нее стака-нчика, последний помещают в формообразующую выт жную матрицу и производ т выт жку с утонением стенок полуфабриката пуансоном, имеющим на наружной поверхности резьбовые канавки. Поре выт жки стаканчика усилие пуансона, оказываемое со стороны его торца на донную часть заготовки, уменьшаетс , в то врем  как дополнительное усилие, передаваемое на внутреннюю боковую поверхность заготовки со стороны бокового профил  пуансона, возрастает , что увеличивает степень деформации заготовки за одни переход выт жки.After the sheet blank is cut and the stack is drawn out of it, the latter is placed in the forming stretch matrix and the thinning of the walls of the semi-finished product is made by a punch having threaded grooves on the outer surface. When the cup is stretched, the force of the punch exerted from its end to the bottom of the workpiece decreases, while the additional force transmitted to the inner side surface of the workpiece from the side of the side profile of the punch increases, which increases the degree of deformation of the workpiece in one transfer transition .

По окончанию выт жки изделие вместе с пуансоном обкатывают, например, роликами, что обеспечивает равномерное распределение металла по профплю резьбы п улучшает свинчивание издели  с резьбового пуасона.At the end of the stretching, the product together with the punch is rolled around, for example, with rollers, which ensures uniform distribution of the metal along the thread and increases the screwing of the product from the threaded section.

Предмет изобретени Subject invention

Способ изготовлени  полых изделий с внутренним резьбовым профилем путем выт л ки заготовк пуансоном с резьбовыми канавками на наружной поверхности, отличаюи{ийс  тем, что, с целью улучшени  качества резьбового профил  на металлических заготовках и облегчени  съема изделп  с пуансона , выт жку осуществл ют с утонением стенки заготовки, а после выт жки заготовку вместе с пуансоном обкатывают роликами.A method of manufacturing hollow articles with an internal threaded profile by extruding a billet with a punch with threaded grooves on the outer surface, distinguished by the fact that, in order to improve the quality of the threaded profile on metal blanks and facilitate the removal of the product from the punch, it is pulled out with thinning the walls of the workpiece, and after stretching, the workpiece together with the punch is rolled on rollers.
