A THREE DIMENSIONS CURVED SURFACE PROCESSING APPARATUS FOR THICK PLATE USING OF HIGH FREQUENCY INDUCTION HEATING BY CONTROLLING AUTOMATIC POSITIONING OF THE COIL

摘要

PURPOSE: A three-dimensional curved surface processing apparatus for a thick plate using high-frequency induction heating by automatic precise positioning a coil is provided to enable rapid heating of the center part of a heating line and the surface part close to a coil in the thickness direction by automatically controlling the movement of the coil. CONSTITUTION: A three-dimensional curved surface processing apparatus for a thick plate comprises a power supply unit(100), a frame(200), a heating unit(300) which implements high-frequency induction heating on a thick plate placed on a work table, a transfer unit which guides the movement of the heating unit or work table, a heat exchanger which passes through one side of the heating unit for cooling, a displacement measuring unit(600) which measures the difference of height of the thick plate before and after heating, and a control unit(700) which controls the operation of the heating unit, the transfer unit, the heat exchanger, and the displacement measuring unit.
