MODULE FOR ELECTROPULSE AND POWER SPHERE-DYNAMIC PLASTICISATION OF PIPELINE BILLET METAL Russian patent published in 2009 - IPC B21J13/02 B21J5/06 B21D37/00 B82B3/00 

FIELD: technological processes.

SUBSTANCE: invention is related to the field of metal plastic working and may be used in manufacturing of multiplane pipelines for pneumatic hydraulic systems of aggregates and machines. Module for electropulse and sphere-dynamic power plasticisation of pipeline billet metal comprises device for electropulse processing and device for power processing with sphere-dynamic impact pulses. Device for electropulse processing comprises current collectors connected to generator of electric pulses, and two faceplates. Faceplates are connected by two vertical stands with elastic elements. One of faceplates has the possibility of reciprocal displacement along vertical stands. Device for power processing has two strikers. Working surfaces of strikers are arranged along differently directed curves of logarithmic spiral of Ya.Bernoulli with different lifting angles.

EFFECT: provision of generation of regulated field of compressive stresses in metal purified from dislocations, which guarantees preservation of geometry of pipelines made of billets.
