Способ горячего экструдирования металла с активным действием сил трения заключается в том, что предварительно нагретую заготовку помещают в контейнер и затем выдавливают через матрицу, определяющую форму и геометрические размеры готового изделия с помощью прессштемпеля при одновременном их перемещении, скорость перемещения контейнера превышает скорость перемещения прессштемпеля примерно в 1,05 - 1,3 раза. Гидравлический экструзионный пресс содержит траверсу, на которой установлен дополнительный цилиндр, внутренняя полость которого гидравлически связана с внутренней полостью цилиндров стабилизации, установленных на задней поперечине пресса, а на плунжере дополнительного цилиндра установлен прессштемпель, который входит в контейнер с заготовкой, с другой стороны контейнера устанавливается матрица с полым прессштемпелем, жестко закрепленным на передней поперечине пресса.The method of hot extrusion of metal with the active action of friction forces lies in the fact that the preheated billet is placed in a container and then extruded through a matrix that determines the shape and geometrical dimensions of the finished product with the help of a press-stamp while moving them simultaneously; 1.05 - 1.3 times. The hydraulic extrusion press contains a yoke on which an additional cylinder is installed, the internal cavity of which is hydraulically connected to the internal cavity of the stabilization cylinders mounted on the rear crossbar of the press, and a press stamp installed on the additional cylinder plunger, which is included in the container with the workpiece with a hollow press-stamp fixed on the front crossmember of the press.
