Automatic plate bending system using high frequency induction heating

摘要

An automatic plate bending system using high frequency induction heating has many universal poles (20,21) for bearing a steel plate (2), a member to be heated, by supporting it from below, the height positions of front end portions of the universal poles themselves being adjustable, and automatically moves a high frequency heating coil (24b) of a high frequency heating head (24) above the steel plate, which is placed on the universal poles, along predetermined heating lines (3) while retaining a constant clearance between the high frequency heating coil and the surface of the steel plate, whereby the steel plate is heated and automatically bent into a desired shape.
