<P>PROBLEM TO BE SOLVED: To provide a heating head of a bending machine for bending a metal plate by high-frequency induction heating, the heating head including a high-frequency heating coil and a matching transformer arranged integrally close to each other, being prevented from rocking during transfer and positioning processes, and being rocked after the positioning process so that the surface of the high-frequency heating coil follows the shape of the bent metal plate. <P>SOLUTION: The heating head is mounted thereon with at least a high-frequency heating coil 1 and a matching transformer 2, and includes: a support mechanism 10 supporting the high-frequency heating coil 1 and the matching transformer 2 rotatably biaxially in a plane in parallel with the surface of the high-frequency heating coil 1; and a restoration mechanism 15 which restores the inclined high-frequency heating coil 1 and matching transformer 2 to initial positions and maintains the high-frequency heating coil 1 and the matching transformer 2 in the initial positions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
