Abstract

Использование: обработка металлов давлением. Сущность: устройство содержит по два силовых двухплунжерных цилиндра, установленных на неподвижных траверсах между каждой парой колонн и св занных гидросистемой с основным цилиндром, а также шайбы с наклонным торцем и клинь  вильчатой формы. Новым в предлагаемом устройстве  вл етс  то, что клинь  выполнены на концах плунжеров, которые вход т в клиновой зазор, образованный опорной поверхностью неподвижной траверсы и наклонным торцем шайб, подложенных под внутренние гайки, а в гидросистеме возле каждого силового цилиндра встроены обратные клапаны. Это позвол ет упростить конструкцию и повысить ее эксплуатационную надежность. 3 ил.Usage: metal forming. SUBSTANCE: device comprises two power double-plunger cylinders mounted on fixed traverses between each pair of columns and connected by a hydraulic system to the main cylinder, as well as washers with an inclined end and a wedge-shaped wedge. What is new in the proposed device is that the wedge is made at the ends of the plungers, which enter the wedge gap formed by the supporting surface of the fixed beam and the inclined end of the washers placed under the internal nuts, and non-return valves are installed in the hydraulic system near each power cylinder. This makes it possible to simplify the design and increase its operational reliability. 3 ill.
