Abstract (en)
This invention relates to a method and apparatus for manufacturing a titanium alloy bolt through a warm forging process. The apparatus includes a feeding device (100) for supplying raw material (W) which is cut into a fixed length from a titanium alloy rod, a loader (200) for carrying the raw material (W) supplied from the feeding device (100), a heating device (300) for heating the raw material (W), a forging device (400) provided with a forging die (420) which fabricates a forging (F) from the heated raw material (W), a guiding device (500) for conducting the heated raw material (W) into the forging die (420), a heat-treating device for heat-treating the forging (F), a peeling device for removing the oxidized layer on the hear-treated forging (F), a machining device for machining the desired portions of the forging (F) from which the oxidized layer is peeled, a form rolling device for forming a thread on an outer surface of the machined forging (F) in order to obtain the titanium alloy bolt, and a cleaning device for cleaning the entire surface of the titanium alloy bolt. Dimensional accuracy and mechanical properties of the titanium bolt, and productivity are improved by the present invention.
