Equipment structure composition

• Heavy duty host frame: thickened steel welded as a whole, treated with aging stress relief, with strong load-bearing capacity, and operates without deformation or shaking.
• Hydraulic tensioning spindle: Multiple sets of slider blade structure, hydraulic drive synchronous tensioning, precise centering of the coil, no deviation during operation, and less likely to collapse of the tail material.
• Drive transmission mechanism: The variable frequency motor is paired with a reducer for smooth transmission, which can synchronize with the speed of the forming host to avoid stretching and wrinkling of the sheet metal.
• Integrated feeding trolley: with integrated walking and lifting functions, it can automatically align the core of the coil, replacing manual lifting by the crane, and complete the transportation and feeding of the coil.
• Pressure material anti roll device: hydraulic pressure arm, presses the outer ring of the coil to prevent the coil from becoming loose or deviating during operation or shutdown.
• Material level sensing system: using a contact type sensing switch to monitor the material quantity in real time, achieve automatic start stop and speed regulation, and ensure the continuity of material feeding.
• Electronic control system: independent electrical control cabinet, easy to operate, with fault alarm and parameter memory functions.
• Dual braking mechanism: pneumatic brake+electromagnetic brake, quickly locks the coil in emergency conditions, eliminating safety hazards.

Core advantages

• Large load capacity fully automatic feeding: With a rated load of 10 tons and a dedicated feeding trolley, the entire process of transportation, alignment, and feeding is automated, reducing the need for manual labor and lifting equipment, and lowering labor intensity.
• High precision and stability of unwinding: Hydraulic centering tensioning+frequency conversion synchronous control, good concentricity of the coil, uniform conveying tension, flat sheet without scratches or deformation, ensuring the quality of back-end molding.
• Durable and sturdy structure: The whole machine is designed for heavy load, with reinforced spindle, frame, and transmission components, supporting 24-hour continuous operation with low failure rate and long service life.
• Multiple safety protections: The pressure arm, dual brakes, limit protection, emergency stop button, and other configurations are fully equipped to effectively avoid problems such as loose rolling and rolling, ensuring production safety.
• Strong universality: Suitable for mainstream large-sized steel coils in the market, it can be matched with various heavy-duty cold bending production lines such as guardrail panels, floor support panels, thick purlins, sandwich panels, etc.
• Easy maintenance: Hydraulic and electrical components are standard universal parts, easy to purchase and replace, only requiring regular lubrication and inspection of hydraulic oil for daily use, with low maintenance costs.
