Abstract

Изобретение относитс  к обработке металлов давлением, в частности к холодной штамповке и может быть использовано в различных отрасл х машиностроени  при изготовлении полых деталей из трубчатых заготовок. Цель изобретени  - расширение технологических возможностей за счет получени  полых деталей типа поворотных угольников. На первом этапе штамповки центральную часть трубчатой заготовки подвергают раздаче. Получают полый полуфабрикат. Затем помещают полуфабрикат в разъемную матрицу 5 штампа. Производ т осевую осадку с воздействием внутреннего гидростатического давлени . Одновременно производ т обжим центральной части полуфабриката в направлении его оси путем воздействи  подвижных вкладышей 6 усилием FA 2 на величину ΔL 2 с каждой стороны. Получают отвод высотой H с диаметром DЪ. Способ позвол ет получить полое изделие сложной конфигурации. 6 ил.The invention relates to the processing of metals by pressure, in particular to cold stamping and can be used in various fields of mechanical engineering in the manufacture of hollow parts from tubular blanks. The purpose of the invention is the expansion of technological capabilities due to the production of hollow parts such as rotary elbows. At the first stage of punching, the central part of the tubular blank is subjected to distribution. Get a hollow semi-finished product. Then put the semi-finished product in a separable matrix 5 of the stamp. It produces an axial draft with an internal hydrostatic pressure. At the same time, the central part of the semi-finished product is crimped in the direction of its axis by the action of the movable inserts 6 with the force FA 2 on the value ΔL 2 on each side. Get tap height H with a diameter of Db. The method allows to obtain a hollow product of complex configuration. 6 Il.
