Abstract
Использование: при обработке металлов давлением и может быть использовано при изготовлении полых сложнопрофиль- ных изделий. Цель изобретени состоит в уменьшении трудозатрат технологической подготовки выполнени профильных элементов издели . Сущность изобретени : в заготовке в виде стакана механической обработкой выполн ют углублени по месту образовани профильных элементов. Полость заготовки заполн ют водой, которую замораживают. При кристаллизации льда за счет выделени внутренней энергии происходит выпучивание утоненных участков на изделии. Высота выпучивани hi зависит от глубины h выполн емого углублени . 6 ил. .Usage: in the processing of metals by pressure and can be used in the manufacture of hollow complex products. The aim of the invention is to reduce the labor costs of the technological preparation of the implementation of the profile elements of the product. SUMMARY OF THE INVENTION: in a blank in the form of a beaker by machining, recesses are made at the place of formation of the profile elements. The preform cavity is filled with water, which is frozen. When ice crystallizes due to the release of internal energy, the thinned areas on the product bulge. The buckling height hi depends on the depth h of the recess being made. 6 ill. .
