MULTIELECTRODE TOOL FOR ELECTRIC-SPARK ALLOYING

摘要

FIELD: electric-spark machining of current conductive materials, namely, for applying wear resistant and corrosion-proof coats. SUBSTANCE: multielectrode tool includes disc electrodes mounted on axle by means of elastic members and mutually insulated for individual power supply from separate electric current sources. elastic members are in the form of coil springs, they are arranged in cavities of disc electrodes. All electrodes are inclined by the same angle relative to rotation axis of tool. Spacing between electrodes and their inclination angle are selected according to conditions providing application of continuous coat at reciprocation motion of tool relative to treated surface of blank. EFFECT: improved design. 3 dwg
