Claims (1)

[Scope of Claim for Utility Model Registration] A press processing device that presses a processing die set at a processing position from above and below using a pressurizing device to perform a predetermined processing on a workpiece, which has at least two fork portions that protrude outward in the radial direction. A turntable is provided rotatably around a vertical axis so that the fork parts support the processing mold, and while one fork part supporting the processing mold is in the processing position, the other fork part is not rotated. Press processing characterized in that a separate processing die can be preset on the press, and the processing die at the processing position and the preset processing die can be exchanged by rotating the turntable. Device.
