Steel Coil-to-Sheet Cutting Machine

Precision Leveler

The primary challenge in thick plate processing is residual internal stress inherent in the coil. In sectors like shipbuilding and heavy machinery, plates often undergo subsequent laser or plasma cutting; if internal stress is not fully eliminated, the plate may warp or deform during cutting. This not only causes jams or damages cutting heads but can also lead to scrapped workpieces, resulting in significant production losses. To address this challenge, KINGREAL SLITTING equips the steel cut to length machine with a heavy-duty precision leveler, ensuring the flatness and stability of the processed plates right from the source.

The leveler features a high-strength welded base and a rigid, integral arch-style frame; this robust structure resists deformation and withstands the continuous, high-impact loads associated with processing thick plates. It utilizes a nine-roller configuration (four upper and five lower rollers)—the optimal design for thick-plate leveling—to meet comprehensive leveling requirements for plates ranging from 6mm to 25mm in thickness. The ends of all work rollers are fitted with heavy-duty rolling mill bearings and unidirectional thrust ball bearings; this dual-bearing protection completely eliminates radial and axial roller movement, ensuring consistent leveling precision during long-term operation.

Additionally, both the upper and lower leveling rollers are supported by three sets of independent backup rollers, significantly enhancing overall strength and rigidity. This prevents roller bending or deformation caused by the pressure of leveling thick plates, ensuring thorough stress relief and uniform flatness across every processed plate—perfectly preparing the material for subsequent high-precision cutting and welding processes.

Intelligent Stacker

Heavy steel plates possess significant mass; when they drop after shearing, they generate immense impact forces. Standard discharge racks cannot withstand such high-frequency, high-intensity impacts, making them prone to frame deformation and equipment damage. Moreover, impacts resulting from free-falling plates can cause surface scratches and edge abrasion, compromising surface quality and the integrity of the finished product.

To address this, the KINGREAL SLITTING steel coil-to-sheet cutting machine incorporates a specialized stacking device that utilizes a synergistic pneumatic-hydraulic system, specifically designed for collecting and stacking heavy plates. This system employs a dual-drive mechanism combining pneumatic and hydraulic power, ensuring smooth operation and high load-bearing capacity to precisely absorb the impact of heavy plate discharge. During the descent, specialized receiving arms support the plate throughout the process, controlling its downward movement at a slow, steady speed. This fundamentally prevents impacts, scratches, and deformation, ensuring comprehensive protection of the plate's surface integrity.

Additionally, the stacker is equipped with high-precision photoelectric sensors that intelligently control the stacking platform's height in real-time. By maintaining an optimal vertical distance between the platform surface and the working level, the system ensures neat stacking and uniform spacing. This technology for the safe, gentle handling of heavy plates resolves common industry challenges—such as discharge damage, disorderly stacking, and equipment vulnerability—enabling the steel coil-to-sheet cutting machine to consistently and reliably handle high-standard heavy plate collection over the long term.
