SEAM WELDING MACHINE HAVING A ROLLER ELECTRODE MACHINING UNIT, CAPABLE OF IMPROVING PRODUCTIVITY BY GRINDING A ROLLER ELECTRODE DURING A WELDING WORK

摘要

PURPOSE: A seam welding machine having a roller electrode machining unit are provided to regularly maintain the welding quality of a workpiece by automatically grinding the edge of a roller electrode.;CONSTITUTION: A seam welding machine comprises a pair of movable carriers, roller electrodes(20,24), and a roller electrode grinding unit. The roller electrode is coupled with each movable carrier. The roller electrode grinding unit is adjacent to the roller electrode and fixed to the main body(10) of the seam welder. The roller electrode grinding unit grounds the edge of the roller electrode by being driven at every predetermined cycle.;COPYRIGHT KIPO 2011
