ELECTRIC ARC EQUIPMENT TO CLEAN SURFACES OF LONG-LENGTH CYLINDRICAL ARTICLES Russian patent published in 1994 - IPC

Abstract SU 1491249 A1

FIELD: mechanical engineering. SUBSTANCE: ring anode of equipment is made in the form of two sectors 2 having reciprocating mechanism 5 for movement in radial direction. Each sector 2 is connected to power supply source in the form of D.C. supply source 6. Gap between sectors 2 does not exceed diameter of machined article. Electric arc equipment also includes screens 3 insulated electrically, embracing machined article out of machining zone, initiation electrode 7, ballast resistor 8, current leads-in 9 to cathode 1 which is machined article located inside ring anode, traction mechanism 10. EFFECT: expanded technological capabilities of equipment thanks to capability to machine articles of different types and sizes. 1 dwg
