The QJ-840-900 double-layer color steel tile forming machine is a high-efficiency cold bending forming equipment with dual types. It can simultaneously produce 840 type roof panels and 900 type wall panels, with one-time feeding and double-layer forming, greatly saving space and investment costs. The whole machine has a high degree of automation, strong structural rigidity, stable forming accuracy, and is suitable for coil materials such as color coated plates and galvanized plates. It is widely used in enclosure projects such as steel structure factories, warehouses, and venues, and is the main model in the building materials processing industry.

Core Structure and Advantages

Double layer integrated rigid frame

• 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 lower layer has 11 rows of 840 roof tiles, and the upper layer has 9 rows of 900 wall tiles, with precise wave patterns and flat surface.
• Wear resistant and durable: The rollers are plated with hard chromium, which is scratch resistant and wear-resistant, suitable for high-strength continuous production.
• Convenient changeover: One click switch between upper and lower layers with electronic control, no need to disassemble, changeover takes 3 minutes.

Frequency conversion+PLC 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 with HRC58-60, and the incision is free of burrs and deformation.
• Guided column shearing, strong stability, cutting accuracy of ± 2mm, no need for secondary trimming of the finished product.

Efficient adaptation, dual-use for one machine

• 840 roof tiles: high wave crest, strong waterproofing, suitable for roofs; 900 wall tiles: wide surface, fast installation, suitable for wall surfaces.
• 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 2000-3000 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, aircraft hangars roofs and walls.
• Public venues: Sports halls, exhibition halls, cinemas, and other enclosed structures.
• Civil buildings: roofs and walls of residential houses, villas, and temporary buildings.
• Supporting engineering: Color steel enclosure projects such as fences, partitions, and ceilings.
