The utility model discloses a drawing machine tool, which relates to the technical field of drawing machines and comprises a track support, a trolley track is mounted on the track support, a trolley slides on the trolley track, and an oil cylinder support is fixedly mounted on the right side of the track support. By means of control of the reversing solenoid valve, when the reversing solenoid valve is powered off, hydraulic oil directly flows back to an oil tank through the reversing solenoid valve, an oil pump does not do work, the oil temperature cannot rise, and when a valve element of the reversing solenoid valve is switched to the left side, the force of an oil cylinder is the product of oil pressure and the difference between the sectional area of a piston and the sectional area of an oil cylinder rod, namely F = P (S-s) and is approximately equal to 10 tons, and the speed is about 1 m/min. The device is suitable for drawing; when the valve core of the reversing solenoid valve is switched to the right s
