FIELD: machine engineering.
SUBSTANCE: machine contains parts in the form of a fixed support and a plunger, on which the opposing tools are mounted. The mating tools form a working cavity for the workpiece and a side channel for extrusion. During the final period of the plunger movement, before reaching the forward dead center, one tool is held relatively to the other by a holding mechanism. At the same time, the tools remain stationary while fixing the configuration of the lateral channel when opposing the pressure forces created in the workpiece. Then, lateral extrusion of the metal of the workpiece is effected through a side channel in which one of the tools is retracted relative to the part of the machine on which it is mounted.
EFFECT: it is possible to obtain parts of different shapes with fewer working positions.
