Abstract
A forging press device for valve including an upsetter in which a plurality of primary forming stages are provided, a forging press main body adjacent to the upsetter, that secondarily forms a primary formed workpiece, and a workpiece conveyance/carry-in device which grips and conveys the workpiece, to carry it into the forging press main body, the device in which the workpiece conveyance/carry-in device is composed of a high speed multi jointed robot capable of circling around a vertical shaft, which has an arm (a chuck) gripping the workpiece. In accordance with the invention, it is possible to provide a forging press device for valve in which the number of deliveries of workpiece from the upsetter to the forging press main body is decreased, which speeds up a valve forging line, and improves the production efficiency.
