DEVICE FOR MACHINE ELEMENTS ELECTRIC RESISTANCE HARDENING AND RECONDITIONING Russian patent published in 2008 - IPC B23K11/06 B23P6/00 

FIELD: electricity.

SUBSTANCE: two arms are mounted on device frame. One end of each arm is coupled with piston compression drive and other end - with electrode tip connected to welding transformer. Screw of screw regulator is mounted on frame base. Regulator nuts are pivotally connected with corresponding arms. Electrode tips consist of two copper half-rings connected to transformer, steel half-rings, spring-loaded truncated rectangular pyramids with grooves in truncated part, guiding isolated screw rods and bronze wire wrapping half of processed element circumference. Spring-loaded truncated rectangular pyramids are mounted along circumference between copper half-rings and by their bases are located in guiding isolated screw rods. Bronze wire is fitted into grooves of spring-loaded truncated rectangular pyramids and is capable to contact with element during its processing. Guiding isolated screw rods are fixed by their threaded part in steel half-rings.

EFFECT: creation of homogeneous surface layer structure and widening the application of electric resistance aggregates in the field of worn-down machine elements reconditioning.
