Principle and Function of Hydraulic Press 返回首頁




Principle of Hydraulic Press



  Hydraulic machine is a machine that uses liquid as working medium and is made according to Pascal's principle to transfer energy to realize various processes. The hydraulic press is generally composed of the machine (host), power system and hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, engineering hydraulic presses and Hydraulic Three-way Presses.


The basic principle is that the oil pump delivers hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper cavity or lower cavity of the cylinder through various one-way valves and relief valves, and moves the cylinder under the action of high pressure oil. A hydraulic press is a device that uses liquid to transmit pressure. When the liquid transfers pressure in a closed container, it follows Pascal's law. The hydraulic transmission system of the four-column hydraulic press consists of a power mechanism, a control mechanism, an executive mechanism, an auxiliary mechanism and a working medium. The power mechanism usually uses an oil pump as the power mechanism, which is generally a product oil pump. In order to meet the requirements of the moving speed of the actuator, select one oil pump or multiple oil pumps

Features of Hydraulic Press


1. It adopts built-in fast cylinder with fast idle stroke speed and high production efficiency;


2. The convenient manual adjustment mechanism can adjust the pressure head or the upper worktable to press at any position in the stroke, and can also adjust the length of the fast forward and the work progress at will within the design stroke;


3. the pressure can be steplessly adjusted according to the process needs;


4. The solid open structure with integral welding can keep the body rigid enough while having the most convenient operating space.


The role of hydraulic press


Numerical control hydraulic press has strong versatility. It is to add pressure sensor to hydraulic machine tool. After data acquisition and system processing composed of microcomputer, it is converted into pressing force value for digital display. When the limit is exceeded, it will send out sound and light alarm and shutdown special Signal, in order to achieve the purpose of automatic control of the pressing force, the load display controller, the display is clear, the control is accurate, the response is fast, the work is stable and reliable, the replacement of different sensors and application software is used for forging equipment and counters with different tonnages The application enables each operator to know the total number and the unqualified number. The addition of two-hand buttons makes the operation of the machine safer.
