Product Introduction
1. The W12 CNC four-roll plate bending machine is equipped with a programmable CNC system, which can store hundreds of automatic rolling data for different workpieces, enabling one-click call and start-up. No manual operation is required, and the machine automatically completes the workpiece rolling.
2. This model not only meets the automatic rolling processing of circular workpieces, but also can meet the automated rolling of various arc-shaped, square, triangular, flat round, oval, and other workpieces.
3. The operating system is equipped with an EPS electronic automatic leveling system, which can automatically adjust the parallelism of the moving axis to ensure product quality.
4. The equipment completes the material feeding, pre-bending, and rolling in one rolling process. The remaining straight edge after pre-bending is 1.5 times the thickness of the plate, and the rolling accuracy is high, which can meet the requirements of automated welding.
5. This model adopts an inverted side roll cylinder technology, which improves the sliding stability and reduces equipment failure, while effectively reducing the body height to meet the requirements of ground installation, thus reducing the user's foundation construction costs.
6. Strictly following the process requirements, the welded parts such as the frame are subjected to annealing and shot blasting treatment to eliminate internal stress, improve the strength and stability of the body.
7. The equipment can be optionally equipped with an internal automatic material lifting frame and an automatic external support frame, which can effectively control the self-weight deformation of the workpiece during the rolling process, assist in rolling, reduce labor, and improve product quality and work efficiency.
8. The equipment can be optionally equipped with a four-roll plate bending machine upper roll conical device technology, which can meet the user's requirements for rolling conical workpieces, and has the advantages of convenient operation, low usage cost, and good rolling quality.

Product Features
Four rollers are made of alloy steel 42CrMo. After rough machining, they undergo tempering treatment with HB240~300, and surface quenching with HRC50-55. According to the JB/ZG4289-86 rolling mill steel standard, the rigidity meets (1/700~1/1000)L (L refers to the distance between the centers of the two frame supports). The hydraulic system consists of a hydraulic pump, valve group, and auxiliary piping components. The hydraulic valve uses the Yuci Yushen stack valve system, with a simple pipeline layout, less leakage, and convenient maintenance and debugging. All input and output ports of the hydraulic system have corresponding testing points for easy maintenance and fault inspection. The ten-inch large screen system has automatic calculation function and automatic generation of rolling process, with a dedicated independent operation panel and remote fault elimination function, enabling one-touch operation, and providing powerful data storage and retrieval functions. Rolling Effect
Dual Roller Drive System
The Chuangtu plate bending machine reliably clamps the sheet material during the pre-bending process, completely avoiding slippage. The dual roller drive ensures more stable and reliable clamping, allowing the edge of the sheet to be closer to the clamping point.
The edge of the sheet being closer to the clamping point is the optimal position for achieving the shortest straight edge length. After the pre-bending is completed, the sheet needs to be moved for further rolling. The full drive method of upper and lower rollers clamps and feeds the sheet from both sides, distributing the clamping and feeding force on both sides of the sheet, ensuring more precise feeding control.
Further explanation: the synchronous movement of the upper and lower rollers can ensure reliable and stable feeding when rolling thin or narrow plates.
Each driven roller is directly connected with a hydraulic motor, ensuring stable and reliable sheet feeding.
The direct connection is a standard feature of Chuangtu equipment, which allows torque to be directly transmitted to the sheet, avoiding power loss.
Other manufacturers' plate rolling machines have driven rollers only on the upper roller. When producing thin or narrow plates, the pressure of the lower roller relative to the upper roller is usually too low, causing slippage, or too high, causing material deformation, and other problems. Furthermore, they usually adopt gearboxes or friction wheel structures, which have low transmission efficiency and significant energy loss.
Optional configuration for the plate rolling machine
Hydraulic vertical support
Provides support when rolling thin sheet materials with large diameters to prevent collapse or overlap;
Precise hydraulic movement, overload protection;
It can align and correct the edge of the sheet material for alignment during spot welding;
It has a steering roller (supporting the inclined conical sheet material) to support the sheet material to maintain the correct diameter throughout the rolling period, rather than using a crane.
Side bracket
Hydraulic tail support (optional)
Prevents collapse or re-opening when rolling thin sheet materials;
Can support the rolled sheet material to maintain the desired curvature.
Tapered Bending Device
The Tapered Device is mainly composed of guide wheel, pin, composite bearing, pressure cover, etc.
Its main function is to guide the wire position during rolling conical, which makes it easy to roll small conical tubes, with simple operation and reliable use.
