Aluminum plate slitting line

High processing precision:

Dimensional precision: It can precisely slit aluminum coil materials into narrow strips of various widths, and the width precision can reach a relatively high level. For example, for thinner aluminum plates (plate thickness ≤1mm), the width precision can be controlled within ±0.05mm. For aluminum plates with a thickness greater than 1.1mm, the width precision is ±0.1mm, meeting the application scenarios with high requirements for aluminum plate dimensional precision.

Straightness precision: The slit strips have good straightness. For example, when the standard high-quality plate has a width greater than 100mm, the straightness of the strip can reach 0.5mm/1000mm, ensuring that the shape of the aluminum plate in the subsequent processing or use process meets the requirements.

Cut quality: The cut is neat, smooth, and has small burrs. Generally, the shearing burr is controlled within 5% of the plate thickness and can be as small as 0.03mm. This not only makes the appearance quality of the aluminum plate good but also reduces the impact of problems such as burrs on subsequent processing or use. For example, when aluminum plates are used in the manufacturing of electronic equipment enclosures, good cut quality can ensure the assembly precision and aesthetics of the enclosure.

High production efficiency:

High-speed slitting: It has a relatively high longitudinal cutting speed. Some advanced aluminum plate slitting lines can reach dozens of meters or even hundreds of meters per minute in longitudinal cutting speed, which can quickly complete the slitting work of aluminum coil materials and greatly improve production efficiency.

Continuous operation: It can realize continuous slitting of coil materials. The entire production line has a high degree of automation. Processes such as uncoiling, longitudinal cutting, and rewinding are carried out continuously, reducing the pause and waiting time in the middle links and realizing efficient batch production.

Multi-knife slitting: It has multiple knife holders and can simultaneously perform multiple passes of slitting on aluminum plates. It can slit multiple narrow aluminum strips that meet requirements at one time, doubling the production efficiency.

Strong material adaptability:

Wide adaptability of materials: It is suitable for aluminum plates of various materials, including aluminum plates with different alloy compositions and hardnesses. For example, common 1xxx series, 3xxx series and other aluminum alloy coils can be slit and processed on the slitting line, meeting the processing needs of various aluminum plate materials in different industries.

Large thickness adaptation range: It can process aluminum plates with a relatively wide thickness range. From thinner aluminum plates (about 0.15mm) to thicker aluminum plates (several millimeters or even thicker), effective slitting can be performed, providing convenience for aluminum plate processing with different thickness requirements.

Product Details

I. Equipment Structure and Components
(1) Uncoiler
Function
It is responsible for loosening the aluminum coil and providing raw materials for the subsequent longitudinal cutting process. It can adapt to coils of different diameters and weights. For example, it can handle aluminum coil with a diameter of 1000 - 2000mm and a weight of several tons.
Structural Features
It usually adopts cantilever type or double-cone head type structure. The cantilever uncoiler has a simple structure and is convenient for loading and unloading coils. The double-cone head uncoiler can better ensure the stability of the coil during the uncoiling process and reduce the shaking of the coil.
(2) Guiding Device
Function
It guides the aluminum plate drawn out from the uncoiler to ensure that the aluminum plate can accurately enter the slitting machine. It can be adjusted according to the width and thickness of the aluminum plate to keep the aluminum plate on the correct running track during the entire processing process.
Types
Common ones are roller-type guiding devices and splint-type guiding devices. The roller-type guiding device guides the aluminum plate through the rotation of multiple rollers, with small friction and little damage to the surface of the aluminum plate. The splint-type guiding device applies appropriate pressure to both sides of the aluminum plate through splints and is suitable for guiding thinner or wider aluminum plates.
(3) Slitting Machine
Tool System
It is the core part of the slitting line. The tools are made of high-quality high-speed steel or cemented carbide and have the characteristics of high hardness and high wear resistance. The number of tools depends on the slitting requirements and can be up to dozens. It can precisely slit the aluminum plate according to the set width. The tool spacing adjustment precision is high, for example, it can reach ±0.01mm to ensure the accuracy of the slitting width.
Shearing Principle
The aluminum plate is sheared by the relative movement of the upper and lower tools. During the shearing process, through precise pressure control, the neatness and smoothness of the cut are ensured. The shearing force can be adjusted according to the thickness and material of the aluminum plate to meet different processing requirements.
(4) Tension Control System
Working Principle
The tension change of the aluminum plate during the processing is monitored in real time through the tension sensor. Then, according to the information fed back by the sensor, the control system adjusts the speed of the motor or the braking force of the braking device to keep the tension of the aluminum plate stable. For example, during the rewinding process, if the tension is too large, the control system will reduce the speed of the rewinding motor; if the tension is too small, the speed of the motor will be increased.
Importance
Precise tension control is crucial for ensuring the processing quality of aluminum plates. Appropriate tension can prevent problems such as wrinkling and deformation of the aluminum plate during longitudinal cutting and rewinding, and ensure the dimensional accuracy and shape accuracy of the slit aluminum plate.
(5) Rewinder
Rewinding Method
There are two ways of center rewinding and surface rewinding. Center rewinding is to wind the aluminum plate on the mandrel. This method is suitable for aluminum coil with a smaller diameter. Surface rewinding is to wind the aluminum plate on the surface of the rewinding roller through friction. This method is suitable for aluminum coil with a larger diameter. The rewinder can automatically adjust the rewinding speed and tension according to the thickness and width of the aluminum plate.
Auxiliary Devices
It is equipped with a pressure roller device, which is used to apply appropriate pressure to the aluminum plate during the rewinding process to make the aluminum coil tighter. At the same time, there is an edge alignment device to ensure that the edge of the rewound aluminum coil is neat and convenient for subsequent handling and use.
II. Technical Parameters
(1) Specifications of Processed Aluminum Plates
Thickness Range
Generally, it is 0.1 - 10mm. Different models of slitting lines may have certain differences in thickness range. Processing thinner aluminum plates requires higher equipment precision and tool requirements.
Width Range
The width range of processable aluminum plates ranges from several hundred millimeters to several meters. For example, the minimum processable width is 200mm and the maximum processable width is up to 2000mm.
(2) Slitting Speed
Speed Range
The common slitting speed is between 10 - 200m/min. High-speed slitting lines can improve production efficiency, but also require higher equipment precision and stability to ensure processing quality.
(3) Slitting Precision
Width Precision
As mentioned earlier, there are different width precision requirements for aluminum plates of different thicknesses. For aluminum plates with a thickness ≤1mm, the width precision can reach ±0.05mm; for aluminum plates with a thickness >1.1mm, the width precision is ±0.1mm.
Straightness Precision
When the standard high-quality plate has a width >100mm, the straightness of the strip can reach 0.5mm/1000mm.
(4) Tension Control Precision
Tension Precision
The tension control precision can generally reach within ±5% of the set tension value to ensure the tension stability of the aluminum plate during processing.
