Title:
HEATING COIL FOR HIGH-FREQUENCY HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157325
Kind Code:
A1
Abstract:
[Problem] To provide a heating coil for a high-frequency heating device, which can efficiently quench a workpiece in a wide range, which is unlikely to be damaged even when the output of a high-frequency power source is increased, and which is also capable of manufacturing products having the same characteristics with good reproducibility, inexpensively, and easily during manufacturing. [Solution] A heating coil 1: is integrally formed using a shaping method in which powder formed from an electrically conductive substance is laid, melted, solidified, and layered repeatedly on the basis of three-dimensional data; and has a pair of plate-shaped grounding sections 2a, 2b to be brought into contact with electrodes for generating a high-frequency current, a pair of plate-shaped support sections 3a, 3b respectively arranged to be orthogonal to the grounding sections 2a, 2b, and a series of circumferential heating sections 4 disposed so as to connect tip parts of the support sections 3a, 3b together. The inner circumferential edge of the heating sections 4 has three immersed portions (slit-shaped portions 5, 5 ...) formed thereon so as to follow the radial direction from the center of the heating sections 4.
