High-Frequency Heating Apparatus for Progressive Die Formability

The heating system is divided into multiple independent high-frequency oscillation members (L1-L4) that can be individually controlled and positioned. Each oscillation member can be independently adjusted along the guide rails to target specific heating locations on the workpiece, allowing selective heating of different regions without requiring a complete system redesign.

The patent replaces conventional thermal heating systems with high-frequency induction heating technology. Instead of using external fire or heating elements, the system uses electromagnetic fields generated by oscillation members to directly induce currents in the metallic workpiece, achieving rapid and precise heating without mechanical contact or complex thermal management systems.

The heating system applies different thermal conditions to different regions of the workpiece. The oscillation members can be positioned to provide concentrated heating at specific locations (such as crack-prone areas or forming zones) while leaving other regions at ambient or lower temperatures. This localized heating approach enables precise control of material properties in critical areas without affecting the entire workpiece.

The oscillation members are mounted on movable structures with guide rails and driving mechanisms that allow dynamic repositioning. The system can adapt the heating locations and patterns based on the specific requirements of different forming operations, enabling flexible and precise thermal processing for various die designs and workpiece configurations.

While the oscillation members are radially arranged to provide uniform heating coverage, each individual oscillation member and its supporting structure can have asymmetric configurations optimized for specific heating requirements. The radial arrangement itself creates a symmetric heating pattern from multiple asymmetric heat sources, achieving uniform temperature distribution across the workpiece surface.

The radial arrangement of oscillation members creates a versatile heating system that can handle various workpiece sizes and shapes. The same basic radial configuration can be adapted for different forming operations by adjusting the number, position, and power of individual oscillation members, making the system universally applicable to multiple heating scenarios without requiring complete redesign.
