THREE-DIMENSIONAL CURVED SURFACE PROCESSING APPARATUS FOR THICK PLATE USING HIGH FREQUENCY INDUCTION HEATING BY CONTROLLING AUTOMATIC PRECISE POSITIONING OF COIL

摘要

Disclosed is a three-dimensional curved surface processing apparatus for a thick plate using high frequency induction heating by controlling the automatic precise positioning of a coil comprising: a power supply means; a frame for supporting a plurality of parts; a heating means for carrying out high frequency induction heating for a thick plate which is secured on a work table; a conveying means for guiding the movement of the heating means or the work table; a heat exchanger for cooling one side of the heating means by cooling water which passes through the heat exchanger; a displacement measuring means for measuring height displacements of the thick plate before and after the heating; and a control means for controlling the operations of the heating means, the conveying means, the heat exchanger and the displacement measuring means. According to the configuration, curved surface processing time and power consumption are noticeably reduced, and the apparatus is environmentally friendly as gas is not used as a heat source unlike in a conventional gas torch type linear heating method. Furthermore, precision in the curved surface processing may be increased by providing the displacement measuring means.
