    Working Principle

    After the motor starts, it drives the connecting rod to move through the belt pulley, reducer and turbine and worm transmission mechanism. The four integral power forming cylinders exert force, outputting strong traction, and applying pressure to the raw materials in the mold, causing raw materials to stretch and form in the mold.

    Application Fields: It is mainly used in the fields of metal sheet stretching and industrial sheet metal forming, such as the stretching process of car parts such as filter housing, exhaust pipe, and radiator cover, and it can also be used in the production of elevator accessories, caps motor end caps, TV back plates, stainless steel tableware, fan casings, pots, and pans.

    Features and Advantages

    • Strong stretching force: It provides greater pressure, allowing materials such as metal sheets to achieve the desired shape and size during the stretching process, suitable for processing various materials with different thicknesses and strengths.
    • Precise control capability: Equipped with advanced control systems, it can precisely control parameters such as pressure, speed, and stroke, ensuring the stability and consistency of stretching process and improving the processing accuracy and quality of products.
    • Multi-functionality: By replacing different molds, it can achieve the stretching and forming of various products of different shapes and sizes, and it can also be used for processes such as correction, pressing, packaging, pelletizing, and pressing plates.
    • Solid structure: The use of four-column structure and frame structure makes the equipment have high strength and rigidity, and it can maintain stable performance during long-term operation, reducing processing errors caused by deformation.

    Selection Points

    • Ton selection: Determine the appropriate ton according to the size, thickness, and stretching force requirements of the workpiece to be processed to ensure the hydraulic press can provide sufficient pressure to complete the stretching process.
    • Table size: The appropriate workbench size needs to be selected according to the size of the work to ensure that the workpiece can be placed on the workbench for processing and that there is enough space to install the mold.
    • Stroke requirements: Consider the maximum stroke of the workpiece during the stretching process, and the stroke of the hydraulic press should be greater than the maximum stretching stroke of the workpiece to ensure that the entire process can be completed.
    • Control method: According to the requirements of the production process and the demand for automation, choose the appropriate control method, such as manual control, semi-automatic control, or fully automatic control, etc.

    Frequently Asked Questions

    Q What are the primary application fields for this CNC four-column hydraulic press?
    It is mainly used for metal sheet stretching and industrial sheet metal forming. Common applications include automotive parts (filter housings, exhaust pipes, radiator covers), elevator accessories, motor end caps, TV back plates, stainless steel tableware, fan casings, pots, and pans.
    Q How does the working principle of the hydraulic press ensure efficient forming?
    The motor drives a connecting rod through a pulley, reducer, and worm transmission. Four integral power forming cylinders exert strong traction and apply pressure directly to the raw materials inside the mold, allowing them to stretch and form efficiently.
    Q What material is used for the four columns, and how is wear resistance achieved?
    The four columns are manufactured from high-strength alloy steel. The surfaces are chrome-coated to provide high anti-wear performance and extend the overall working life of the equipment.
    Q What are the key selection points when choosing a specific model?
    Key selection factors include determining the appropriate tonnage based on workpiece thickness, selecting a suitable table size for the mold, matching stroke requirements to the maximum stretching depth, and choosing the right control method (manual, semi-automatic, or fully automatic).
    Q Can this hydraulic press handle different types of molds?
    Yes, by replacing the molds, it can achieve the stretching and forming of various products of different shapes and sizes. It is a multi-functional machine also suitable for correction, pressing, packaging, pelletizing, and pressing plates.
