Induction heat-treating of threaded fasteners with a rotary conveyor |
摘要 |
A system and method for inductively heating and then quench hardening a portion of a workpiece, such as a several threads of a screw or bolt are disclosed. The system includes a conveyor system having a rotary conveyor for separating, aligning, and transporting each of the workpieces in aligned succession through an induction heater positioned about the rotary conveyor to heat-treat at least a portion of each of the workpieces. A sensor determines whether a workpiece is heat-treated to a minimum temperature and causes an ejector to separate heat-treated workpieces that have reached the minimum temperature from heat-treated workpieces that have failed to reach the minimum temperature. The separated workpieces are then quenched in a tank & separately removed automatically.
