What is a hydraulic press?

Definition of Hydraulic Press

The hydraulic press is a type of machine that uses liquid as a working medium to transfer energy, based on Pascal's principle, to perform various tasks.

Typically, a hydraulic press is made up of three components: the mainframe, the power system, and the hydraulic control system.

    Brief introduction to hydraulic press

    Hydraulic press (also known as hydraulic oil press) uses the static pressure of a liquid to process materials such as metal, plastic, rubber, wood and powdered products.

    It is commonly used in pressing and forming processes, including forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy and pressing.

    Working environment

    The function of the working medium used in a hydraulic press is not only to transfer pressure, but also to ensure that the components of the hydraulic press are sensitive, reliable, long-lasting and have minimal leakage.

    The basic requirements for a working medium in a hydraulic press are:

    1. Good fluidity and low compressibility to improve transmission efficiency.
    2. Anti-rust properties.
    3. Good lubricating performance.
    4. Easy to seal.
    5. Stable performance and long-term stability without deterioration.

    Historically, water was used as a working medium in hydraulic presses.

    Later, emulsified liquid was introduced by adding a small amount of oil to water to improve lubrication and reduce corrosion.

    Mineral oil was later introduced as a working medium in hydraulic presses in the late 19th century. The oil had good lubricity, anti-corrosion properties and moderate viscosity, which improved the performance of hydraulic presses.

    In the second half of the 20th century, a new type of water-based emulsifying solution was developed, characterized as “oil in water” rather than “water in oil”.

    This solution had oil-like properties, including good lubricating and anti-corrosion properties, but with the added benefit of containing little oil and being less flammable.

    However, the higher cost of water-based emulsions has limited their widespread use.

    In general, punching machines have a simple structure, fast production speed and high efficiency, making them suitable for simple and high-volume forming.

    On the other hand, hydraulic presses are more suitable for producing medium to small batches with a need for precision, depth and variable shape.

    These presses have precise requirements for speed, pressure and slider position and can be customized to meet specific orders.

    When customers want to purchase processing machines, they must choose the appropriate hydraulic or mechanical press based on their actual processing needs.
