Three-dimensional curved surface processing apparatus for thick plate using high frequency induction heating by controlling automatic precise positioning of coil

Abstract

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.

Description

technical field [0001] The invention relates to a thick plate three-dimensional curved surface processing device that automatically and precisely controls the position of a high-frequency induction coil, especially the high-frequency induction heating can be used due to the automatic and precise control of the coil position, and has a displacement measuring component that can measure the thickness of the thick plate before heating. / After the height direction is displaced, it is a three-dimensional surface processing device for thick plates that provides more precise surface processing. Background technique [0002] The shipyard designs the shape of the ship for optimum performance, taking into account factors such as the appropriate cargo capacity, speed, and fuel consumption rate, according to the purpose of use of the ship and the requirements of the ship owner. The outer plates of the hull are mostly three-dimensional curved surfaces, and the outer plates defined by the...

Problems solved by technology

However, due to the local heating of the thick plate 30, this thermal processing method cannot accurately control the temperature, resulting in unexpected deformation of the material; at the same time, due to problems such as heating direction, speed, heating amount, cooling method, and thickness of the plate, it will affect the operation. Quality, so that the bending rate of the thick plate is out of control, making the operation difficult

[0010] In addition, under the trend of pursuing automation, the heating speed is relatively slow, which makes the technology impractical, and at the same time emits a large amount of carbon dioxide, emits noise, and causes various environmental pollution; not only that in the construction of the thermal deformation database and thermal deformation. There are also many difficulties in controlling
