ELECTRIC-SPARK CUTTING OUT MACHINE Russian patent published in 1997 - IPC

FIELD: electric-spark procession of blanks by wire electrode. SUBSTANCE: electric-spark machine includes coordinate table for mutual motion of blank and wire electrode and coordinate for determining angle and direction of inclination of said wire electrode. Guides for wire electrode are arranged on arms of two joint-type parallelograms, arms are placed along the same straight line. Mutually opposite arms of said parallelograms are telescopically connected one with another. One of adjoining arms of lower parallelogram is jointly mounted on upper support fixed relative to upper parallelogram. One arm of upper parallelogram parallel relative to the above mentioned adjoining arm is jointly mounted on two-coordinate table for determining angle and direction of inclination of wire electrode. Upper guide of wire electrode is arranged on slide that may move along arm of upper parallelogram in rails mounted on arm. It maintains coaxiality of wire electrode guides and also angle and direction of wire electrode. EFFECT: improved design. 1 dwg
