PRESS-HAMMER Russian patent published in 2010 - IPC B21J11/00 B21J9/02 B21J13/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metal deformation process and can be used in technological machinery for implementation of punching operations. Press-hammer, containing weight dropper and table, is outfitted by platform with cavity. Platform consists of two parts, connected from top side by steel plates. In cavity of platform it is located plunger-punch. With parts of platform it is connected mould. In cavity of plunger-punch it is located resilient member, connected with letter by means of rods. Press-hammer is outfitted by filled rammed bulk material by pipes with chokes and installed in cavities of pipes by plungers. Weight dropper is implemented in the form of platform with located from both sides hooks. Plunger-punch is implemented with located in top part hooks, connected to hooks of platform of weight dropper by means of ropes. From bottom part plunger-punch bearing on resilient member, mould, top planes of plungers, rammed bulk material, chokes and rock.

EFFECT: there is provided decrease in value of manufacturing of production accessories and vibration reduction.
