METHOD FOR MANUFACTURE OF PARTS FROM MATERIALS WITH DISORDERED STRUCTURE (VERSIONS) AND DIE MOLD FOR AXIAL PRESSING OF BOTTOM AND BUTT OF BLANK FOR PARTS SUCH AS LONG-LENGTH REVOLUTION BODY WITH AXIAL HOLE FROM MATERIALS WITH DISORDERED STRUCTURE (VERSIONS) Russian patent published in 2009 - IPC B21F45/00 B41F21/00 B30B15/02 

FIELD: technological processes.

SUBSTANCE: in the first version of method realisation, blank bottom is additionally shaped. At that formation of bottom and long-length part of blank is done simultaneously with the help of mandrel with needles. Afterwards blank bottom and butt are axially pressed in any sequence. Then long-length part of blank is radially pressed. In the second version of method realisation blank bottom is additionally shaped from previously manufactured tape of small width by its rolling up in roll. Afterwards blank is shaped in the form of long-length revolution solid with axial hole, from previously made tape of larger width, by its winding onto roll. Afterwards blank bottom and butt are axially pressed in any sequence. Then long-length part of blank is radially pressed. In die mold made according to the first version, puncheons are arranged in the form of revolution solids, and in the first one working butt fully covers cross section of cartridge cavity, and the second puncheon is arranged with axial hole, through which free end of rod is passed, being fixed with its other end in cartridge. Die mold according to the second version is additionally equipped with rod, fastening elements and detachable gasket. Puncheons are arranged in the form of revolution solids, in the first one working butt fully covers cross section of cartridge cavity, and the second puncheon is arranged with axial hole, through which free end of rod is passed, being fixed with its other end in cartridge. Fastening elements for fixing of puncheons to cartridge are provided in both puncheons. At that the second one is fixed to cartridge through detachable gasket arranged with thickness equal to working travel of this puncheon.

EFFECT: production of new products, which were not earlier manufactured by industry.
