Introduction
CNC hydraulic plate metal rolling bending machine is a plastic forming machine tool that continuously bends sheet metal, widely used in industries such as boilers, shipbuilding, petroleum, carpentry, and metal structures. The main components of the hydraulic plate metal rolling bending machine include upper and lower rollers, frame, reducer, unloading device, and base. The electronic control system consists of an electrical control cabinet, an operating console, and a power supply, and has overload maintenance function. When lifting the hydraulic plate metal rolling bending machine safely, attention should be paid to the angle of the steel wire rope, the use of large and small hooks, and anti unhooking measures. Primapress brand specializes in producing metal sheet metal processing machinery such as CNC bending machines.
CNC plate hydraulic plate metal rolling bending machine is a plastic forming machine that continuously bends the sheet metal. Generally, a symmetrical three roll plate hydraulic plate metal rolling bending machine leaves a certain width of dead edges on both ends of the sheet metal when rolling. After being rolled into a cylinder, the pre bending function is to remove the dead edges and combine them into a cylinder. The workpiece produced by the plate hydraulic plate metal rolling bending machine has many straight edges at both ends and needs to be welded before rolling, which is time-consuming and reduces work efficiency.
Main components of the hydraulic plate metal rolling bending machine
- Upper Roller: Usually located symmetrically in the center between the two lower rollers. It moves vertically by the action of hydraulic oil in the hydraulic cylinder on the piston, enabling the pre-bending and final forming of the plate.
- Lower Roller: Acts as the driving roller, installed in fixed bearings. It is driven to rotate at the same speed in the same direction by a motor through a gear reducer. It is thecore part of the entire rolling process.
- Side Roller: Used in a four-roller plate rolling machine, it assists the upper and lower rollers in completing complex rolling tasks. It usually has a pre-bending function and can complete the pre-bending of the plate ends and the forming of the workpiece in one feeding operation.
- Frame: Includes left and right frames and a fixed side frame, supporting the entire equipment to ensure its stability and reliability.
- Drive System: Provides the power source, including the motor and hydraulic system, ensuring the synchronous movement and precise control of each roller.
- Electrical Parts: Includes a CNC control system for program editing and operational control, enabling the plate rolling machine to automatically complete complex rolling tasks.
- Discharge Device: Used to remove the finished product from the machine after the rolling process is complete.
- Base: The foundational part that supports the entire machine, ensuring the stability of the equipment.
- Hydraulic System: Transmits pressure through hydraulic oil to drive the vertical movement of the upper roller and the bending and forming of the plate.
- Guiding Device: Guides the plate into the rolling device for processing, ensuring machining accuracy.
The CNC plate rolling machine is to use external forces such as hydraulic or mechanical force to move the working rollers, thereby bending or rolling the plate into shape. Specifically, the upper roller is symmetrically located between the two lower rollers and moves vertically by the action of hydraulic oil in the hydraulic cylinder on the piston. The final gear of the main reducer drives the meshing gears of the two lower rollers to provide torque for rolling the plate. Depending on the rotational movement and positional changes of the working rollers of different shapes, elliptical parts, arc parts, cylindrical parts, and other components can be processed.
CNC plate rolling machines can process a variety of profiles, including metal plates and non-metallic plates. For example, carbon steel plates, aluminum plates, stainless steel plates and manganese plates. They can adapt to various thicknesses from thin plates to thick plates. CNC plate rolling machines use a high-precision control system to achieve fast and accurate curling of plates. They can process and roll metal sheets into various parts such as cylinders, cones and curved plates.
For example, the 3 roller plate rolling machine clamps and curls the plate through the main drive of the upper roller and the vertical lifting movement of the lower roller. The forming process of the CNC plate rolling machine is simple and efficient. By passing the metal plate through a continuous three-point bending process, the plate is tightened between the upper and lower rollers, and the friction between the upper and lower rollers is used to drive the movement of the plate. Through the feeding movement of the side rollers, the bending moment required for deformation is applied to the plate. In this way, the relative position change and rotation of the upper and lower rollers and the side rollers can cause the plate to undergo continuous elastic-plastic deformation, and a formed part with both quality and precision that meets the requirements can be obtained.
This process can shape profiles into various forms, such as O-shaped, U-shaped, or multi-section R-shaped. This equipment is widely used in metal processing, shipbuilding, boiler manufacturing, aerospace, hydroelectric engineering, the chemical industry, and machinery manufacturing.
Main Functions of CNC plate rolling machines
Multiple shape processing
Depending on the different working roller designs, CNC plate rolling machines can process parts of various shapes, such as elliptical parts, arc parts, cylindrical parts, etc., to meet diverse industrial needs.
- Bending flat metal sheets or plates into cylindrical shapes
This is achieved by passing the plate between rotating rollers, which apply pressure to bend the material.
- Creating cones and tapers
CNC metal cone rolling machine can also be used to create cones or tapers by adjusting the relative position of the rollers. This allows the production of parts with different diameters along the length.
- Achieving complex shapes and contours
With CNC control, CNC plate rolling machines can produce parts with complex shapes, such as mixed radii, stepped diameters, or irregular contours. This capability makes CNC plate rolling machines highly versatile.
Multi-axis control
Control multiple axes to achieve complex bending and rolling operations, enabling the creation of complex designs and shapes.
Pre-bending function
Many CNC plate rolling machines have a pre-bending function, which can pre-bend the ends of the plate before rolling to avoid misalignment or deformation during the rolling process to ensure minimal flat spots and high-quality final products.
Multi-Radius Bending
CNC plate rolling machines can perform multi-radius bending, making it suitable for producing complex and intricate workpieces. Bends a profile into multiple curves with varying radii along its length. Instead of having a uniform radius throughout the bend, the profile may smoothly transition from one radius to another, creating a complex shape. Critical in applications where aesthetics, material strength, and fatigue resistance are important. Multiple radius bends can create complex shapes and contours, which are valuable for custom and precise designs.
CNC plate rolling machines allow programming of specific rolling sequences and parameters, which can be stored and reused for consistent production. Due to the use of CNC control, it provides high precision in the rolling operation, ensuring consistent and repeatable results.
