Steel wire winding hydraulic press includes hydraulic press and hydraulic press. A hydraulic press is called one that uses water-based liquid as the working medium, and one that uses oil as the working medium is called a hydraulic press. The specifications of wire winding hydraulic press are generally expressed in nominal working force (kilonewtons) or nominal tonnage (tons). Steel wire winding hydraulic presses for forging are mostly hydraulic presses with high tonnage. To reduce equipment size, large forging hydraulic presses commonly use higher pressures (around 35 megapascals), and sometimes even use ultra-high pressures above 100 megapascals. Steel wire winding hydraulic presses for other purposes generally use a working pressure of 6-25 megapascals. The tonnage of hydraulic press is lower than that of hydraulic press The working principle of wire winding hydraulic press. The areas of the large and small plunger are S2 and S1, respectively, and the force exerted by the hydraulic press for wire winding on the plunger is F2 and F1, respectively. According to Pascal's principle, the pressure of a liquid is equal everywhere. The gain effect of hydraulic pressure is the same as mechanical gain, where the force increases but the work does not gain. Therefore, the movement distance of the large plunger is S1/S twice that of the small plunger.
