  • FREE-BENDING FORMING APPARATUS FOR TUBULAR COMPONENT MADE OF DIFFICULT-TO-DEFORM MATERIAL USING DIFFERENTIAL TEMPERATURES AND METHOD THEREOF
    Publication number: 20230191472
    Abstract: A free-bending forming apparatus for a tubular component using differential temperatures and a method thereof are disclosed. The apparatus includes an isothermal heating device and a heating device for the differential temperatures. The isothermal heating device is configured to preheat an inside and an outside of a bending section of the tubular component to a predetermined temperature to form a preheated bending section before bending and forming. The heating device for the differential temperatures is configured to heat the inside and the outside of the preheated bending section of the tubular component respectively to different temperatures, and the temperature at the outside is higher than that at the inside. The heating device for the differential temperatures is provided between a pressing device and a guiding mechanism, and the isothermal heating device is provided between the pressing device and the heating device for the differential temperatures.
