4 Rolls Plate Rolling Machine

4 Rolls Plate Rolling Machine can roll various metal plates efficiently and accurately through advanced technology and structural advantages. It is widely used in concrete mixer trucks, bridge casings, LNG gas tanks, boilers and other fields, and has high production efficiency. and rolling quality.

Machine Introduction

The CNC four rollers have a pre bending function at the end of the sheet metal, which can load the sheet metal in one go without turning the head to complete the pre bending at the end of the sheet metal and the rolling and forming of the workpiece.

The working roller on the machine is the main driving roller, and the lifting of the lower roller and both sides of the roller are driven by hydraulic transmission. The lifting displacement is controlled by a computer, automatically leveled, and displayed on the screen, and the tilting and resetting of the flipping bearing body are driven by hydraulic transmission. The tail of the upper roller is equipped with a balance mechanism, which can facilitate the unloading of the rolled workpiece and cylinder. Equipped with a mobile independent operating table that can be moved and operated at any time, the machine is equipped with a safety interlock device.

The machine has a high technical level, full functionality, high accuracy, and convenient operation, making it an ideal CNC rolling equipment in contemporary times. It is the ideal preferred model for rolling circular, arc, conical, square, and multi segment arc shaped workpieces in industries such as energy, transportation, petroleum, chemical, boiler, shipbuilding, hydropower, and metal structures.

Details

Dual drive motor (with mechanical brake and bidirectional balance valve to ensure dual braking).

Accumulator (for the straightening protection roller shaft and hydraulic system in the subsequent process of welding the cylinder).

Adopting the most advanced heavy-duty linear guide rail structure.

High quality roller shaft forging material, subjected to rigorous heat treatment hardening process, and surface polished.

Unique angle pre bending structure CEIA ®, to achieve better pre bending effect, the straight edge of the plate head can be controlled within ≤ 1.5 times the plate thickness.

Unique inverted hydraulic push side roller oil cylinder CIOC ® The system brings the following technological advantages:

By combining the oil cylinder and slider, an integrated side roller sliding oil cylinder is cast as a whole, greatly increasing the contact area between the slider and the slide rail and improving the stability of the side roller sliding.

The combination of the oil cylinder and slider shortens the length of the slide rail, lowers the height and center of gravity of the overall equipment, and reduces the cost of infrastructure construction.

The inverted installation structure protects the sealing ring, improves the service life of the oil cylinder, and reduces the maintenance rate of equipment failures.

Unique rolling system CECB ®, can achieve smaller cone diameter.

High standard independently developed hydraulic systems, including on/off valve control systems, proportional valve control systems, and electro-hydraulic servo systems.

1. What is the difference between four-roll coiler and three-roll coiler?

A four-roll coiler has four rollers, which are the top roller, bottom roller and two side rollers. In contrast, a three-roll coiler has only three rollers. The four-roller structure can realize high efficiency and high precision pre-bending effect through the cooperation of rollers and shafts, and improve the production efficiency.

2. What is the pre-bending effect of the four-roller coiler?

When the four-roller coiler is used for pre-bending, the remaining straight edge can be controlled at ≤ 1.5 times the thickness of the rolled plate, which is far better than the effect of the three-roller coiler, and saves production materials and subsequent rounding time.

3. What are the automatic calculation functions of four-roller plate rolling machine?

Four-roller plate rolling machine is equipped with self-developed automatic calculation function, which can realize automatic rolling round, rolling arc, rolling square, rolling abnormal shape and other functions, greatly improving the production efficiency and operation convenience.

4. How is the rolling time of four-roller plate rolling machine?

Taking the general specification of drums as an example, the rolling time of four-roller plate rolling machine is only about 2 minutes, and the rolling time of four-roller plate rolling machine is only about 2 minutes.
