In a press machine equipped with a Gui cushion 3 for adjusting press pressure, a hydraulic cylinder is used as the cylinder radar 3 for the Gui cushion, and an oil chamber on the pressure adjustment side is installed. A leaf valve 25 is connected, and a variable magnetic force electromagnet 31 is installed in the relief knob (lube 25) so that the relief operating pressure can be changed by changing the magnetic force. A cam member 16 is provided on one of the elevating member 13 and the press machine frame 1, and a cam follower 18 that engages with the force spring member 16 is provided on the other. A converting device 19 for converting the driven momentum into an electric signal is connected to the driven movement portion of the cam member 16 due to the cam action, and the converting device 19 and the electromagnet 31 are connected, and the electromagnet is activated in response to the driven momentum. A press machine characterized in that the magnetic force of the press machine 31 is changed.2 The lifting member 13 is supported by the pillar 2 of the press frame 1 so as to be able to move up and down, and is also supported by a biasing means such as a spring 15. The press machine according to claim 1, wherein an upward moving force is always applied, and as the slide 7 moves downward, it comes into contact with a portion 8 of the slide and is moved downward. 3. The cam member 16 is detachably attached to the elevating member 13, and the cam follower 18 is rotatably supported by the column 2 of the press frame 1.
Press machine as described in section. 14. The press machine according to claim 3, wherein the converting device is a differential transformer 19, and a cam follower 18 is connected to the movable core 24 of the converter.
