PRESS HAMMER Russian patent published in 2008 - IPC B21J11/00 B21J9/02 

FIELD: mechanic.

SUBSTANCE: press hummer contains guiding tubes, a dropping weight, and a moving platform with cylindrical cavities and a lower stamp matrix. The cavities, in which plungers are placed, are filled with loose material to a height of 0.1 - 1000 mm. The press hummer is provided with conductor pipes filled with sand up to a height of 0.1 - 195.5 m. In the pipe cavities, plungers are located, supported by elastic elements, sand, and rock. The plungers in the cylindrical cavities of the platform are supported the loose material, which thrusts to their upper plane, for providing deformation of the sheet in the lower stamp matrix, while their lower plane thrusts to the plungers in the conductor pipes. The dropping weight is designed as a lower platform with an upper stamp matrix and cylindrical cavities filled with loose material to a height of 0.1 - 1000 mm. In the mentioned cavities, plungers are also installed. On the lower platform, the upper stamp matrix and the upper solid platform are placed and connected with it.

EFFECT: increases accuracy of part production; increases lifetime of process equipment and decreases noise and vibration.
