The utility model relates to a guide device of yawing force can balance in press, including slider guide rail, slider guide rail electromagnet device, fuselage guide rail, pressure sensor and press machine body, slider guide rail and the electromagnet device on the slider guide rail set up in groups, fixed connection constitutes slider guide device jointly on the slider, electromagnet device and fuselage guide rail on the fuselage guide rail set up in groups, and fixed connection constitutes fuselage guide device jointly on press machine body's stand, pressure sensor fixes between fuselage guide rail and press machine body, slider guide device and fuselage guide device set up in pairs. The device introduces electric magnet technology, and through pressure sensor device and electromagnet device's application, under the condition that does not change press structural style, it is balanced to make slider produced yawing force in the motion process pass through the electromagnetic force, therefore the life of the machining precision of press and guide rail obtains improving.
