METHOD OF METALS PRESSING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC B21C23/14 B21J5/00 B21C25/00 B21J13/02 B82B3/00 

FIELD: technological processes.

SUBSTANCE: for one technological operation two types of pressing are carried out. As one type direct pressing of metal is used from container to its exit via calibrating zone. The second type is equal-channel angular pressing with provision of shift deformations in metal. Direct pressing is carried out prior to angular pressing. Shift deformations at angular pressing are provided immediately after metal exit from calibrating zone of direct pressing. Pressing is performed in the device that contains puncheon, matrix with two crossing channels and container. Container is installed above the matrix. Container cavity forms inlet part of vertically installed matrix channel. Area of inlet part cross section exceeds cross section area of vertically installed channel. The latter is arranged in the form of calibrating belt for direct pressing of metal from container. Height of belt makes 4-10 mm, and its diameter is equal to diameter of matrix second channel.

EFFECT: production of long-length items with high mechanical properties from different structural materials with simultaneous reduction of power intensity.
