Primary Quality:

Our Full Hydraulic Drive Plate Rolling Machine offers a multitude of primary qualities that set it apart from other rolled plate machines:

  1. Adjustable Clamping Pressure: The machine provides the flexibility to adjust the clamping pressure between the upper and lower rollers. This feature ensures optimal pressure for different thicknesses and widths of plates, resulting in precise and consistent rolling without slippage. The ability to control the clamping force contributes to increased productivity, with up to 50%-80% higher productivity compared to three-roller coilers.

  2. Safety and Reliability: Our machine prioritizes safety and reliability. The hydraulic drive system and advanced design guarantee safe and dependable operation, minimizing the risk of accidents or equipment malfunctions. With enhanced safety measures, operators can work with peace of mind and focus on their tasks.

Main Body Overview:

The hydraulic system of our Full Hydraulic Drive Plate Rolling Machine comprises a hydraulic pump, valve group, auxiliary pipeline parts, and more. The machine utilizes a superimposed valve system developed by the Yuci Oil Research Institute, ensuring a simple pipeline layout, minimal leakage, and easy maintenance and troubleshooting. Each input and output port of the hydraulic system is equipped with a corresponding detection point, simplifying maintenance and fault inspection. Furthermore, the placement of the hydraulic station on the base simplifies the machine’s foundation and transportation.

Main Structure:

The main structure of our machine consists of an upper roller device, lower roller device, side roller device, main transmission device, tipping device, left and right side frames, and chassis. The upper roller serves as the driving roller and is powered by a hydraulic motor. The lower roller and side rollers are driven rollers. The side rollers move up and down along the guide rail of the frame, and their rotation is facilitated by the friction between the steel plate and each roller. Hydraulic cylinders control the rising and falling of the lower roller and side rollers, as well as the flipping and resetting of the inverted head, enabling precise and asymmetrical bending and rolling.

New Rolling Bearings for Rolling Mills:

To enhance energy efficiency, our machine incorporates new rolling mill bearings for the upper, lower, and side rolls. These rolling bearings significantly reduce the power consumption of the main motor while greatly improving non-slip conditions. The use of upper and lower roller drive technology eliminates the need for a distribution box, resulting in improved main transmission efficiency, extended bearing life, reduced frictional resistance, and the ability to roll thinner steel plates. The bottom and side rolls employ extra-wide series of large double-row self-aligning roll bearings, facilitating tilting and avoiding mechanical interference when rolling cones.

Transmission System:

The transmission system of our machine consists of the main drive and secondary drive.

  • Main Drive: The upper roll serves as the driving roll and is directly coupled to a hydraulic transmission device comprising a planetary reducer, hydraulic motor, balance valve, overload valve, etc. This setup ensures refined and efficient operation.

  • Secondary Drive: The lifting of the lower roller is driven by two oil cylinders, offering high synchronization accuracy. The displacement data of the cylinders is detected by a displacement sensor, further enhancing precision and control. The rollers on both sides are driven by friction to rotate. The side roller lifting cylinders are connected to the side roller bearing seat, ensuring synchronized lifting and providing clear displacement feedback on the screen for convenient monitoring and control.
