The QJ-686-760 double-layer color steel tile forming machine is a dual type high-efficiency cold bending forming equipment. The upper layer produces 686 type trapezoidal roof panels, and the lower layer produces 760 type arc-shaped water ripple tiles. It is a one-time feeding, double-layer independent forming machine that balances high strength and high drainage. The whole machine has strong rigidity, high forming accuracy, and high degree of automation. It is suitable for coil materials such as color coated sheet and galvanized sheet, and is widely used in roof and wall engineering of steel structure factories, warehouses, residential buildings, villas, etc. It is a cost-effective main model for building materials processing.

Core Structure and Advantages

Double layered heavy-duty rack

• Adopting 300H steel integral welding, stress relief after welding, medium plate thickening design, long-term heavy load without deformation or shaking; Double layered upper and lower layout, saving 50% of land occupation, suitable for projects with limited space.

Precision forming roller set

• Layered molding: The upper layer has 14 rows of 686 trapezoidal tiles with high wave peaks, strong strength, and good load-bearing capacity, while the lower layer has 16 rows of 760 corrugated tiles with smooth arcs, fast drainage, and high surface value.
• Wear resistant and durable: The rollers are plated with hard chrome, which is scratch resistant, wear-resistant, and does not peel off the paint, suitable for high-strength continuous production.
• Easy to change: One click electronic control to switch between upper and lower layers, no need to disassemble, quick change in 3 minutes.

PLC+touch screen intelligent control

• Touch screen operation, can set length, quantity, speed, and store parameters with one click.
• Fault self check alarm, automatic shutdown, beginner can get started in 1 hour, single person on duty.
• Variable frequency speed regulation ensures smooth operation, low noise, and energy savings of over 30%.

Hydraulic guide column shearing system

• The blade material is Cr12MoV, heat-treated HRC58-60, and the incision is free of burrs, deformation, and edge breakage.
• Guided column shearing, strong stability, cutting accuracy of ± 1mm, no need for secondary trimming of the finished product.

Dual use, high cost-effectiveness

• 686 trapezoidal tile: high strength, large span, suitable for industrial factory and warehouse roofs; 760 water ripple tile: beautiful appearance, smooth drainage, suitable for residential, villa and wall decoration.
• Shared feeding and electrical control, one set of equipment=two single machines, significantly reducing equipment procurement and operation costs.

Product performance characteristics

• Dual type efficiency: Simultaneously producing two types of tile types, with a daily production capacity of 2500-3500 square meters, suitable for large-scale orders.
• High quality molding: The board surface is flat, the paint pattern is uniform, the wave shape is regular, and the waterproof and strength are excellent.
• Stable and durable: The core components are finely processed, with few vulnerable parts, low continuous operation failure rate, and long service life.
• Easy installation: The finished tiles are tightly overlapped and easily fixed, increasing construction efficiency by over 40%.
• Low operation and maintenance costs: simple structure, easy maintenance, daily maintenance only requires regular lubrication.

Application Scope

• Industrial buildings: steel structure factory buildings, warehouses, locomotive depots, roofs and walls.
• Civil buildings: roofs for residential houses, villas, and new rural construction.
• Public venues: sports halls, exhibition halls, scenic area building enclosures.
• Supporting projects: color steel enclosure projects such as fences, ceilings, and simple houses.
