Longitudinal Shearing and Rewinding Line
In terms of production efficiency:
High-speed cutting and rewinding: The longitudinal shearing and rewinding line usually has a high operating speed and can complete the longitudinal cutting and rewinding operations of the coil in a short time. Some advanced equipment can run dozens of meters or even hundreds of meters per minute, which greatly improves the production efficiency and meets the needs of large-scale production.
Automated continuous operation: This equipment adopts an automated control system, which can realize continuous operation of the whole process from coil loading, cutting, rewinding to unloading. It reduces manual intervention and labor intensity, and at the same time avoids production interruptions caused by manual operation, further improving the overall production efficiency.
In terms of cutting accuracy:
High-precision cutting: The longitudinal shearing and rewinding line is equipped with high-precision cutting tools and an advanced positioning system, which can accurately control the cutting width and size. The cutting error can be controlled within a very small range, generally reaching an accuracy of ±0.1mm or even higher, ensuring that the width of the cut coil is uniform and consistent, and meeting the production requirements of various high-precision products.
Good edge quality: By optimizing the tool design and cutting process, the longitudinal shearing and rewinding line can make the edge of the coil smooth, free of burrs and tearing during the cutting process, improving the edge quality of the coil. This is very important for subsequent processing and use. For example, in the electronics industry, high-quality edges can avoid damage to electronic components.
In terms of rewinding quality:
Precise tension control: The equipment has an advanced tension control system, which can adjust the tension in real time according to factors such as the thickness and material of the coil during the rewinding process to ensure that the tension of the rewound coil is uniform. This helps to prevent problems such as loose winding and wrinkling of the coil during the rewinding process, ensures the flatness and compactness of the rewinding, and improves the storage and transportation performance of the coil.
High rewinding neatness: The longitudinal shearing and rewinding line adopts a precise rewinding mechanism and guiding device, which can make the cut narrow coils be neatly rewound on the reel. The end face of the rewound coil is neat without unevenness, which is convenient for subsequent packaging and use.
In terms of product adaptability:
Applicable to multiple materials: The longitudinal shearing and rewinding line can be applied to coils of various materials, such as stainless steel, carbon steel, aluminum alloy, copper alloy, plastic film, etc. By replacing different types of tools and adjusting process parameters, it can meet the cutting and rewinding requirements of coils of different materials, and has strong versatility.
Strong processing ability for wide coils: This equipment can process coils of various widths, and coils ranging from a few tens of millimeters wide to several meters wide can be longitudinally cut and rewound. The processing of wide coils not only improves the utilization rate of materials, but also reduces subsequent processes such as splicing, reducing production costs.
In terms of equipment stability:
High-quality equipment components: The key components of the longitudinal shearing and rewinding line, such as motors, reducers, tools, bearings, etc., usually adopt high-quality materials and advanced manufacturing processes, and have good wear resistance, corrosion resistance and reliability. These high-quality components can ensure the stability of the equipment under long-term high-load operation and reduce the occurrence frequency of equipment failures.
Complete fault diagnosis and protection system: The equipment is equipped with a complete fault diagnosis system, which can monitor the running status of the equipment in real time. Once abnormal situations are detected, such as tool wear, motor overload, abnormal tension, etc., the system will immediately issue an alarm signal and take corresponding protection measures, such as automatic shutdown, to avoid further damage to the equipment and improve the safety and stability of the equipment.
Basic Composition
Loading Part
Loading Trolley: It is used to transport the steel plate coil from the storage area to the position of the uncoiler. It is usually electrically driven and has a certain load-bearing capacity and movement precision.
Uncoiler: It supports and releases the steel plate coil. There are types such as hydraulic expansion and contraction type and mechanical expansion and contraction type, which can be adjusted according to the inner diameter of the coil to ensure the stable rotation and feeding of the coil.
Pretreatment Part
Straightening Machine: It eliminates the original bending, warping and other defects of the steel plate, keeping the steel plate flat before it enters the subsequent processes. It is generally composed of multiple sets of straightening rolls arranged up and down, and the straightening effect is achieved by adjusting the pressing amount of the rolls.
Flattening Machine: It further improves the flatness of the steel plate. By applying appropriate pressure to the steel plate, it eliminates the internal stress, making the surface of the steel plate smoother and flatter.
Shearing Part
Slitting Machine: It is the core component, composed of the frame, cutter shaft, cutters, etc. Multiple disc cutters are installed on the cutter shaft. By precisely adjusting the spacing between the cutters, the wide steel plate is longitudinally cut into narrow strips of the required width. The cutter material usually adopts high-speed steel or cemented carbide to ensure the cutting precision and service life.
Scrap Edge Rewinder: It collects the scrap edge materials generated during the slitting process and winds them into rolls for convenient subsequent processing and recycling.
Rewinding Part
Tensioner: It provides appropriate tension during the rewinding process, ensuring that the steel plate is tightly and neatly wound and avoiding problems such as loose winding and wrinkling.
Rewinder: It winds the cut narrow strips of steel plate into rolls. There are different forms such as single-shaft, double-shaft or multi-shaft. It can be selected according to the production requirements. The rewinder has functions such as automatic centering and tension control to ensure the rewinding quality.
Discharging Part
Discharging Trolley: It transports the wound finished product coils from the position of the rewinder to the storage area, making it convenient for subsequent handling and storage.
Working Process
Loading: The loading trolley transports the steel plate coil to the uncoiler, and the uncoiler unwinds the coil.
Pretreatment: The steel plate passes through the straightening machine and the flattening machine in sequence to eliminate the unevenness and stress of the plate.
Slitting: The pretreated steel plate enters the slitting machine and is longitudinally cut according to the preset width.
Scrap Edge Treatment: The scrap edges generated during the cutting are collected by the scrap edge rewinder.
Rewinding: The cut narrow strips of steel plate maintain a certain tension under the action of the tensioner, and then are rewound by the rewinder.
Discharging: After the rewinding is completed, the discharging trolley transports the finished product coils away.
