A plate rolling machine is a common forging machine equipment that can bend metal plates such as carbon steel plates, copper plates, stainless steel, aluminum and other materials into cones, cylinders or other shapes.
It is used in various fields such as light, medium and heavy steel products, aerospace, building structures, and petrochemical equipment. Based on the different number of work rolls, it can be divided into three roll plate rolling machine and four roll plate rolling machine. Today we will mainly introduce the four roll plate rolling machine.
The CNC 4-roller plate roll bending machine is a common sheet metal processing equipment that uses four or more rollers to continuously rotate and roll the sheet metal into a curved shape.
Compared with ordinary plate rolling machines, CNC 4-roller plate roll bending machines use digital control systems, which have a higher degree of automation and accuracy. The four roll plate rolling machine is suitable for bending and forming metal sheets. It can roll circular, curved, and conical workpieces within a certain range, and has a pre bending function at the end of the sheet. The remaining straight edge is small, the work efficiency is high, and the metal sheet can be roughly leveled on this machine.
The CNC 4-roller plate roll bending machine bends through two sets of upper and lower rollers, and adjusts the position of the left and right rollers to achieve more precise control of sheet metal. The upper roller is fixed in position, while the lower roller moves linearly upwards to clamp the steel plate.
The two side rollers move in a straight or curved line towards the upper roller to adjust the curvature radius of the drum. The roller motion forms of the four roll and three roll plate rolling machines are different, but their working principles are the same, both using the principle of three-point circle determination to roll different radii. But the straight edges and roundness of the pre bent four roll bending machine are better than those of the three roll bending machine.
The 4-roller plate roll bending machine can load metal sheets in one go without the need to turn the head to complete the pre bending and rolling forming of the sheet ends. The remaining straight edges are small, making it an ideal equipment for rolling circular and curved workpieces.
The upper working roller of the four roll plate rolling machine is the main driving roller, driven by a hydraulic motor and reducer, while the lower roller is the auxiliary driving roller, also driven by a motor.
The side roller is a passive roller, and the lifting of the lower and side rollers is hydraulic transmission. The lifting displacement is controlled by a computer, automatically leveled, and displayed on the screen with a digital display.
The synchronization accuracy is ± 0.15mm. The flipping and resetting of the flipping bearing body is driven by hydraulic pressure, and the tail of the upper roller is equipped with a balancing mechanism, which can facilitate the unloading of the rolled workpiece and cylinder.
The machine is equipped with a mobile independent operating platform for convenient use by workers and a safety interlock device. It has full functions, high precision, and easy operation. It is the most ideal preferred machine type for rolling circular, curved, and conical workpieces in industries such as petroleum, chemical, boiler, shipbuilding, hydropower, and metal structures.

- The lower and side rollers of the four roll plate rolling machine can be tilted at one end and can rise and fall together in the tilted state, which is beneficial for the rolling of conical workpieces.
- The four roll plate rolling machine is equipped with a movable operation platform, which is more convenient for operators to use. The touch screen displays the positions of the four work rolls, making it clear to the operator at a glance.
- The sensors for the lifting displacement of the lower and side rollers of the four roll plate bending machine adopt high-precision sensors to ensure position accuracy and achieve position monitoring of each roller.
- The main electrical components of the electrical part are selected from high-quality products such as Schneider, which have the characteristics of long service life and long fault free time.
- The hydraulic pipeline joints all use cone sealed quick fit joints, which have reliable radial seals to ensure that the hydraulic system does not leak oil during operation.
- The hydraulic system has suction and return oil filters to ensure the cleanliness of the system, an air filter to ensure normal breathing and water evaporation of the oil tank, and a dual channel safety protection device in the system to ensure the safe use of the equipment.
- The flip bearing body (flip head) is equipped with a tilt cylinder, which can tilt and stand up for easy material retrieval of the workpiece. The flip and reset of the flip bearing body are equipped with interlocking devices. After the flip bearing body is flipped, other actions are in standby mode, and can only be restored after the flip bearing body is reset, providing safety protection.
- The tail of the upper roller is equipped with a balancing device, which balances the upper roller while flipping the bearing body. When the inverted head flips and discharges the material, the upper roller is in a balanced state by the balancing mechanism, making it easy to remove the cylindrical workpiece.
- The four-roll plate rolling machine adopts a solid base with strong rigidity, easy lifting and installation. The frame and base are both welded structures and undergo annealing aging treatment to eliminate internal stress and improve the accuracy of the plate rolling machine. The whole machine structure is composed of building blocks, with a beautiful shape and easier maintenance.
The application of numerical control technology enables the equipment to have fast and efficient production capacity. While saving time, the position and bending angle of the rollers can be adjusted according to the needs, resulting in good energy-saving effects.
The digital control system can perform automated control with small precision differences and high production efficiency. At the same time, it can achieve various specifications of rolling plates and complete a large number of complex workpieces.
