Plate rolling machines can be divided into the following types according to their working principle, structural form, number of rollers and processing methods used:
Прокатная машина с тремя роликами
Rolling Machine Whit Three Rollers is the most common type and is widely used for the curling of metal plates. The structure is mainly composed of three rollers, usually:
Upper roller: used to adjust the pressure up and down to push the plate down or up.
Lower roller: The two lower rollers are usually fixed.
Working principle: The upper roller interacts with the two fixed lower rollers by moving up and down, so that the plate is gradually formed between the rollers.
Прокатная машина с тремя роликами is relatively easy to operate and is suitable for processing plates of various thicknesses. It can roll cylinders or rolls of different diameters.
Four-roller plate rolling machine
Compared with the three-roller plate rolling machine, the four-roller plate rolling machine has an additional roller, usually two lower rollers and two upper rollers. It has better stability and accuracy, and is suitable for plate rolling processing that requires higher precision.
Working principle: The four-roller system can provide more uniform pressure, reduce deformation of the plate, and have better control effect.
Advantages: It can avoid the problem of the two ends of the plate warping during the curling process of the three-roller plate rolling machine, and is suitable for thicker or harder plates.
Double Roller Plate Rolling Machine
Double roller plate rolling machine is the simplest type, usually used for processing thin plates or small batches.
Working principle: two rollers, the plate rotates between the two rollers, and the upper roller provides pressure to complete the bending forming.
Scope of application: suitable for thinner metal plates, simple operation, and low requirements for thick plates or high precision.
CNC plate rolling machine
CNC plate rolling machine is a modern high-precision plate rolling equipment equipped with a CNC system, which can be automatically controlled by a computer program.
Features: The operation is more precise, and the bending angle, curling radius and bending pressure can be accurately controlled, which is suitable for the processing of plates with complex shapes.
Scope of application: widely used in large-scale plate processing requiring high precision and high efficiency, especially the curling of thick plates.
Hydraulic plate rolling machine
Hydraulic plate rolling machine uses a hydraulic system to drive and adjust the pressure of the roller.
Working principle: The hydraulic system provides precise and adjustable pressure, which can achieve higher curling accuracy and is suitable for thicker or harder materials.
Features: It can control the change of roller pressure, and the operation is more flexible and precise than the mechanical transmission plate rolling machine.
Mechanical transmission plate rolling machine
Mechanical transmission plate rolling machine is a traditional plate rolling equipment that uses mechanical parts such as gears and chains to drive the rollers.
Features: Suitable for mass production, but its adjustment accuracy is slightly inferior to that of the hydraulic system.
Scope of application: Generally suitable for the curling of conventional thin plates, medium and thick plates.
Pipe bending plate rolling machine
Pipe bending plate rolling machine is specially used for bending metal pipes or round plates, and is suitable for special projects that need to be bent into arcs or rings.
Application: Commonly used in the production of pipes, ducts, boilers and other components.
Manual plate rolling machine
Manual plate rolling machine is usually used for small and low-capacity plate processing, and the operation is manually adjusted by adjusting the roller pressure and position.
Features: Suitable for small batch, low-cost production, commonly used in small workshops or maintenance operations.
The type and function of the plate rolling machine mainly depends on the thickness, width, required bending accuracy and production scale of the plate. Choosing the right plate rolling machine can improve production efficiency and finished product quality.
