Steel wire winding hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. The wire winding hydraulic press is generally composed of three parts: the main machine (host), the power system, and the hydraulic control system. The wire winding hydraulic press (also known as the hydraulic press) is a mechanical device that uses liquid pressure transmission and is made according to Pascal's law. There are many types of wire winding hydraulic presses. Of course, the uses are also diverse according to needs. According to the type of liquid that transmits pressure, there are two main categories: hydraulic presses and hydraulic presses. The total pressure generated by a hydraulic press is relatively high and is commonly used for forging and stamping. Forging hydraulic presses are divided into two types: forging hydraulic presses and free forging hydraulic presses. Die forging hydraulic presses require molds, while free forging hydraulic presses do not require molds. Wire winding hydraulic press is a machine that uses liquid as the working medium to transfer energy and achieve various processes. Steel wire winding hydraulic press can be used not only for forging and forming, but also for straightening, pressing, packaging, pressing blocks, and pressing plates.
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.
The working medium used in the wire winding hydraulic press not only transmits pressure, but also ensures the sensitivity, reliability, long service life, and minimal leakage of the machine's working components.
According to structural types, wire winding hydraulic presses can be divided into double column, four column, eight column, welded frame, and multi-layer steel strip winding frame types. Medium and small-sized vertical wire winding hydraulic presses also have C-shaped frame types. In the vertically mounted four column free forging steel wire winding hydraulic press, the oil cylinder is fixed in the upper beam, and the plunger is rigidly connected to the movable crossbeam. The movable crossbeam is guided by the column and moves up and down under the pressure of the working fluid. There is a workbench on the crossbeam that can move forward and backward. Install upper and lower anvils respectively under the activity crossbeam and on the workbench. The working force is borne by a frame composed of upper and lower beams and columns. Large and medium-sized free forging hydraulic presses driven by pumps and accumulators often use three working cylinders to obtain three-level working force. There are also balance cylinders and return cylinders that apply upward force outside the working cylinder.
