1. Introduction to the Equipment
Customer: What does a purlin roll forming machine do?
Sales: This machine is specifically designed to cold-form metal sheets (such as galvanized sheet and color-coated steel sheets) into C-shaped, Z-shaped, and other cross-section purlins. It is primarily used for roof and wall supports in steel structures. It is fully automated and highly efficient.
2. Process Advantages
Customer: Does this machine require heating the metal sheet during processing?
Sales: No, it uses a cold-formed process, gradually shaping the sheet through multiple sets of rollers at room temperature. This saves energy while preserving the sheet's original mechanical properties, saving over 60% energy compared to traditional hot-rolling processes.
3. Level of Automation
Customer: Does the production process require much manual effort?
Sales: Almost none! From coil loading and guide correction to roll forming, cutting to length, and finally to finished product delivery, the entire process is automated. The PLC control system allows for precise parameter settings, minimizing manual errors and ensuring reliable batch production. 4. Applications of C-Section Steel Purlin Machines
Customer: I want to build a factory building with a 10-meter span. Which machine model is suitable?
Sales: We recommend the C-Section Steel Purlin Machine. The C-Section purlins it produces have a compact cross-section and are lightweight. They can be directly bolted to the main frame, making installation easy. They are ideal for small and medium-sized buildings with spans of 6-15 meters and offer a very high cost-performance ratio.
5. Features of the Z-Section Steel Purlin Machine
Customer: Which purlin machine is best for a large-span building like a gymnasium?
Sales: The Z-Section Steel Purlin Machine is more suitable. The upper and lower flanges of the Z-Section purlin overlap and interlock, forming a monolithic load-bearing structure with strong wind resistance and load-bearing capacity. It is suitable for spans of 15-30 meters and can be used safely in areas with heavy snow and strong winds.
6. Advantages of Multifunctional Machines
Customer: Our order specifications vary. Do you have a more flexible machine?
Sales: Of course! The multifunctional purlin machine is equipped with modular roll dies. Die changes take only 30-60 minutes. It can accommodate various cross-sections, such as C-shaped, Z-shaped, and U-shaped rolls, and can accommodate sheet metal thicknesses ranging from 0.8 to 3mm, making it ideal for businesses with diverse specifications.
7. Function of the Unwinding Rack
Customer: Is there anything special about the unwinding rack?
Sales: It uses a hydraulic tensioner to securely clamp coils of varying diameters. It also features an automatic alignment function to prevent sheet metal from wandering during transport, which is crucial for subsequent forming accuracy.
8. Function of the Guide Device
Customer: What should I do if the sheet metal wanders during transport?
Sales: Don't worry. The guide device features correction wheels and limit plates that monitor deviation in real time. A fine-tuning mechanism dynamically adjusts the deviation, ensuring the sheet metal always enters the forming unit in the optimal position, avoiding dimensional errors.
9. Core of the Roll Forming Unit
Customer: Is the roll die durable?
Sales: Very durable! The forming unit has 15-25 sets of rollers made of high-strength alloy steel. After quenching, the hardness reaches over HRC55. It withstands long-term, high-intensity processing without deformation. The spacing and angle of each roller can be fine-tuned by servo motors to accommodate different sheet materials.
10. Cutting Device Accuracy
Customer: Is the cut purlin length accurate?
Sales: Very accurate! We use a hydraulic flying saw cutting system. The cutting speed is synchronized with the conveyor speed, allowing us to cut to length without stopping the machine. The cuts are smooth and burr-free, and the length tolerance is controlled within ±1mm, making it completely adaptable during installation.
11. Control System Operation
Customer: Is the equipment complex to operate? Is it easy for workers to use?
Sales: It's very simple! It's based on a PLC controller with a touch screen. Workers can directly set parameters such as length, thickness, and speed. It also has a fault diagnosis function. If a problem occurs, an audible and visual alarm will sound and the machine will shut down, making it easy for even novice operators to master it quickly.
12. Production Efficiency
Customer: How many meters of purlins can this equipment produce per hour? Sales: The continuous production speed can reach 10-30 meters per minute. Based on an 8-hour shift, we can produce up to 15,000 meters, which is 5-8 times the speed of traditional welding processes and is particularly powerful for mass production.
13. Material Utilization
Customer: Is there a lot of waste during processing?
Sales: Almost no waste! The continuous rolling process doesn't cause shearing waste like stamping does, and the material utilization rate can reach over 95%. Over the long term, the material cost savings alone are significant.
14. Compatible Plate Range
Customer: What plate specifications can be processed?
Sales: It's highly adaptable. We can process plate thicknesses from 0.8-3mm and widths from 100-300mm. Purlin lengths can range from 1 meter to 12 meters, covering virtually all building specifications.
15. Industrial Plant Application
Customer: We're building an industrial plant. Will this equipment produce enough purlins?
Sales: Absolutely! The purlins produced by this product serve as the load-bearing framework of the roof, stably supporting the loads of large roof systems. They are also quick to install, expediting factory construction and are being used by many factories.
16. Compatibility with Logistics Warehouses
Customer: What are the benefits of using this type of purlin in logistics warehouses?
Sales: The biggest benefit is lightweighting! The purlins' low weight reduces the overall weight of the warehouse without compromising load-bearing capacity, improving warehouse space utilization and making them particularly suitable for logistics storage.
17. Suitability for Harsh Environments
Customer: We are located in a snowy area. Can the purlins withstand the pressure?
Sales: Absolutely! Z-shaped purlins, in particular, are overlapped to form a monolithic structure, offering strong resistance to wind loads and snow pressure. They are specifically designed for harsh environments like heavy snow and strong winds, ensuring safety.
18. Compatibility with Curtain Wall Systems
Customer: Can these purlins be used in the curtain wall system of a steel-structured office building?
Sales: Of course! Precision-machined purlins have minimal dimensional tolerances and work seamlessly with curtain wall systems, ensuring structural stability without compromising the building's appearance. This equipment is used in many office building projects.
19. Promoting Green Buildings
Customer: Does this equipment contribute to green building?
Sales: It does! The cold-bending process is energy-efficient, the purlins are lightweight, and building material consumption is reduced. The production process is environmentally friendly and fully meets green building requirements. Many environmentally friendly projects now prioritize purlins produced using this equipment.
20. Supporting Building Industrialization
Customer: Why is this equipment considered a core component of building industrialization?
Sales: Because it can mass-produce high-precision, standardized purlins, it's compatible with the modular construction of steel structures, speeding up construction and reducing labor reliance. This aligns perfectly with the development direction of modern building industrialization and is an indispensable key piece of equipment.
