A hydraulic press is a type of mechanical machine made based on Pascal's principle. During operation, the hydraulic oil is pumped and distributed to the upper or lower chamber made of oil, and the pressure is transmitted through the liquid to drive the power structure to work. Generally, a hydraulic press consists of three parts: the machine itself, the power system, and the hydraulic control system. There are various structural types of hydraulic presses, including vertical hydraulic presses, horizontal hydraulic presses, double-column hydraulic presses, four-column hydraulic presses, and eight-column hydraulic presses.July Machinery will take you to understand the working principle of hydraulic presses.

The principle of a hydraulic press is to use liquid as the working medium to transfer energy and realize various industrial processes. This is based on Pascal's principle, which states that the pressure applied to a confined fluid is transmitted uniformly in all directions. When a hydraulic press is in operation, the oil pump delivers hydraulic oil to the integrated plug-in valve block, and the hydraulic oil is distributed to the upper or lower chamber of the oil cylinder through various one-way valves and overflow valves. Under the action of high-pressure oil, the oil is moved, and the power structure is driven to perform work.

The structure of a hydraulic press generally consists of three parts:

1. The machine itself provides the main structure and is mainly composed of columns, upper beams, movable beams, and lower beams.
2. The power system, that is, the hydraulic cylinder, provides power for the hydraulic press.
3. The hydraulic control system, driven by the power system, controls the direction and pressure of the hydraulic oil to realize the working process of the hydraulic press.

The structure of a hydraulic press is not complex, but there are various structural types. According to the direction of the acting force, it can be divided into horizontal hydraulic presses and vertical hydraulic presses. Most hydraulic presses are vertical, while hydraulic presses for extrusion are mostly horizontal. According to the main machine structure, it can be divided into double-column hydraulic presses, four-column hydraulic presses, eight-column hydraulic presses, welding frame hydraulic presses, and multi-layer steel strip winding frame hydraulic presses, and other types.
