するプレス加工装置。In a press processing device that performs press working by lowering an upper mold facing a fixed lower mold, the upper mold is divided into a plurality of parts, and at least one of the divided molds is an upper mold that is moved up and down by the press device. While the remaining split molds are directly fixed to the holder, the mold surface of the remaining split molds is positioned below the mold surface of the split mold fixed to the upper mold holder when the upper mold is raised, and the remaining split molds are In this case, the cylinder is attached to the upper mold holder via a cylinder equipped with a pressurizing force transmission release mechanism so that the vertical positions of each mold surface are different, and the pressurizing force transmission releasing mechanism Two communicating passages are formed to connect the upper chamber to a pressurized fluid supply source, and to communicate the upper and lower chambers of the cylinder to the piston connected to the split mold via a rod.1. A pressure release valve that closes one of the communication passages by being normally biased by an elastic member and opens the communication passage by contacting a stopper provided at the top of the cylinder after press forming is completed by lowering the split mold; Usually, the cylinder is biased to close by an elastic member, and if the pressure in the lower chamber of the cylinder is higher than the pressure in the upper chamber, the piston is provided with a return valve that opens a communication passage against the elastic member. A press working apparatus characterized in that the pressurizing timing of the plurality of divided dies is varied.
