Hydraulic Press Machine Basic Principle

February 01, 2025
    In the forging and pressing of steel, including the forming of metal structural parts, and even the pressing of plastic products and rubber products, a mechanical equipment is required. What is it? Yes, it is a hydraulic press. Hydraulic press is a device that uses hydraulic transmission technology for pressure processing and can be used to complete various forging and pressure forming processes.

    Currently, different types of hydraulic presses are needed in many industries or fields of machinery production. For example, in the heavy machinery manufacturing industry, 800-ton presses and 1,000-ton presses mainly use hydraulic pressure. In the aviation industry or plastic and non-ferrous metal processing industry, hydraulic presses are mainly used for the molding of plastic products. For pressure The size is not important. Generally, 300-ton presses and 200-ton presses are used. However, at present, hydraulic presses have become important equipment necessary for the machinery production industry.
 
 What is the working principle of a hydraulic press? Let the editor of Weike tell you! According to the pressing process requirements, the main cylinder of the hydraulic press can complete the basic steps of rapid descent, deceleration, pressing, pressure maintaining delay, pressure relief return and stop (any position) working cycle, and the pressure, speed and holding time need to be adjustable. The ejection hydraulic cylinder is mainly used to eject workpieces and is required to be able to achieve ejection, retraction, and stop actions. For example, when the thin plate is stretched, auxiliary actions such as rising, stopping and pressure return of the ejection hydraulic cylinder are required. Sometimes it is necessary to use a blank holder to compress the blank to prevent wrinkles around it.
 
 The hydraulic press takes the maximum pressure (tonnage) that the main actuator (master cylinder) can output in the main movement as the main specification of the hydraulic press, and has been serialized. The tonnage of the top cylinder is often 20% to 50% of the tonnage of the main cylinder. The ejection cylinder of the extruder can use about 10% of the main tonnage. The tonnage of the blank holder cylinder of a double-action drawing hydraulic press is generally about 60% of the tonnage of the drawing cylinder. The speed of the master cylinder is determined by the needs of the pressure processing technology. Generally, in a hydraulic system directly supplied by a pump, the working stroke speed does not exceed 50mm/s, and the fast forward speed does not exceed 300mm/s. The fast reverse speed of the hydraulic press is the same as the fast forward speed. The speeds are equal.
