Material preparation table
Used for preparing steel coil loading, the workbench is lined with nylon plates to prevent scratches. It can store up to 2 steel coils and has a load capacity of 20 tons. The hydraulic cylinder on the pre-loading platform for steel coils can move left and right. Used for preparing steel coil loading, the workbench is lined with nylon plates to prevent scratches.

Feeding device
The sheet material is fed into the feeding and drawing machine, which consists of a swinging guide plate and a telescopic scraper plate. These components are mounted on the frame of the straightening and drawing machine. The guide plate and scraper plate are swung and extended/retracted respectively by hydraulic cylinders. Clamping and positioning: This mechanism is used for lateral positioning of the steel sheet to prevent it from shifting out of alignment. On both sides, there are vertical rollers fixed to sliding seats; the sliding seats can be manually adjusted to accommodate different sheet widths. The vertical rollers are quenched and chrome-plated. The entire system is manually controlled and comprises side guiding rollers and other similar components.
Hydraulic Uncoiler + Coil Unwinding Device
The single-arm support hydraulic expanding and contracting claw mechanism: After the coil handling cart is positioned, the expanding and contracting claws enter the inner bore of the steel coil to tighten it. Then, the unwinding machine descends to apply pressure and manually unrolls the coil. A variable-frequency motor is activated to rotate and guide the coil end into place. The unwinding machine can move laterally by ±150 mm and is equipped with a robotic arm assembly. The machine body and base are welded from steel plates; the main spindle features surface hardening and grinding using special steel. Internal sliding blocks and other components are made of cast steel. The hydraulic cylinder’s expansion and contraction range is up to 50 mm, and it is fitted with an emergency brake for immediate stop and tension control. The emergency brake is also used for tension control along the production line. The unwinding power is provided by a variable-frequency motor. The unwinding machine’s cantilever structure is mounted on the unwinding machine’s base. The frame is constructed from mild steel and structural steel profiles, while the rollers are welded steel tubes coated with high-performance elastomer.
Feeding cart
The material-handling trolley is equipped with both vertical lifting and horizontal movement capabilities, making it easy to insert the inner bore of steel coils into the expanding and contracting cylinder of the unwinding machine. The lifting mechanism is driven by a hydraulic system, while the horizontal movement is powered by a geared motor. The trolley features a four-column guiding system for smooth lifting and lowering. The top of the trolley is fitted with a V-shaped groove lined with PU rubber sheets, as well as a safety movable cover plate. The main body of the trolley is constructed from steel plates. The wheels and wheel axles are made of special alloy steel and undergo surface hardening treatment. The lifting rails are made of steel pipes coated with hard chrome. The contact surfaces between the trolley and the steel coils are fitted with thick rubber pads on inclined planes.
Product Applications
Specialty Metals & Composite Materials Processing
Aerospace components, medical devices, and chemical container materials.
Titanium alloys, nickel-based alloys, and composite metal plates—highly complex machining is performed using blades made from special materials (such as cemented carbides and ceramic coatings) and heavy-duty leveling machines.
Precision Electronics AndElectrical Appliances
Transformer core, motor stator and rotor laminations, heat sinks, conductive connectors.
Silicon steel sheets, electrolytic copper strips, and alloy foils → Leveling machine (to relieve internal stress and ensure electromagnetic performance) → Slitting machine (for ultra-precise edge trimming with no burrs) → Flying shear (for fixed-length cutting)
New Energy Applications
Wind power: Thick steel plates—after being leveled—are used for the manufacture of tower sections and components.
Lithium batteries: Ultra-thin copper and aluminum foils are slit with extremely high precision by slitting machines—this is the core process. Leveling machines and flying shear machines may be used in the processing of casing materials. Photovoltaics: Aluminum frame profiles are rolled → leveled → slit → then sheared into flying shear mode to produce frame segments.
Automotive & Auto Parts Manufacturing
Body panels (doors, hoods), structural components (bumpers, chassis parts), seat frames, etc.
High-strength steel and aluminum alloy coils → Leveling machine (for precision leveling, critical for stamping) → Slitting machine (provides coil stock of specific widths for various parts such as door inner panels and longitudinal beams) → Flying shear (supplies fixed-length sheet metal for large-scale stamping lines).
Architecture & Building Materials Industry
Steel structural roofing/wall panels, curtain wall panels, and ceiling profiles.
Color-coated steel sheet, aluminum-magnesium-manganese coil, stainless steel coil → Leveling machine (corrects edge waviness) → Slitting machine (cuts into widths required for roof panels and wall panels) → Flying shear machine (cuts to fixed lengths for on-site installation)
Home Appliance Housing & Component Manufacturing
The outer shells and internal structural components of refrigerators, washing machines, air conditioners, and microwave ovens.
Cold-rolled steel sheet, galvanized sheet, and color-coated coil → Leveling machine (ensures a smooth and aesthetically pleasing surface) → Slitting machine (cuts into strips of varying widths for refrigerator door panels, side panels, and other components) → Flying shear (cuts the sheets into specified lengths) → Stamping/bending.
