Abstract:
A method of forming a component includes providing a work-piece blank from a formable material. The method also includes engaging the work-piece blank with a transfer device. The method additionally includes austenitizing the work-piece blank in the transfer device via heating the blank to achieve austenite microstructure therein. The method also includes transferring the austenitized blank to a forming press using the transfer device. The method additionally includes forming the component via the forming press from the austenitized blank and quenching the formed component. A work-piece blank transfer system includes a transfer device having clamping arm(s) for engaging, holding, transferring, and releasing the work-piece blank. The transfer device also includes a heating element configured to austenitize the work-piece blank via heating the blank to achieve austenite microstructure therein. The transfer system additionally includes an electronic controller programmed to regulate the heating element and the clamping arm(s).
