Product Introduction:
- Fully Automatic CZ Interchange: Utilizes advanced PLC control to switch between C and Z profiles in just 1-5 minutes without dismantling any parts, changing rollers, or replacing cutters.
- High-Precision Roll Forming: Features premium 45# forged steel rollers with hard chrome plating and precision machining to guarantee consistent dimensions with tight tolerances (±0.5mm to ±1mm).
- Universal Cutting & Punching: Equipped with a universal cutter and multi-station hydraulic punching system that accommodates all sizes within the machine's range, eliminating the need for tool changes.
- High-Speed Continuous Production: Driven by hydraulic or servo motors, the machine achieves fast forming speeds (10-30 m/min) while maintaining strict dimensional accuracy for large-scale projects.
- Intelligent PLC Control: Features imported brand PLC and touch screen interface for easy operation, automatic size adjustment, accurate length measurement, and reliable fault detection.
Product Description & Parameters:
The CZ Purlin Roll Forming Machine is a state-of-the-art cold roll forming equipment designed to manufacture both C and Z steel purlins on a single production line. Widely used in industrial buildings, warehouses, and steel structure construction, this machine revolutionizes purlin production by eliminating the need for separate C and Z machines. The core advantage lies in its fully automatic interchangeable system, where the operator simply inputs the desired profile and dimensions on the touch screen, and the PLC controls the rollers to adjust automatically. The machine processes galvanized or cold-rolled steel coils through decoiling, leveling, hydraulic punching, roll forming, and automatic cutting. The rollers are manufactured from high-grade 45# forged steel or GCr15 bearing steel with hard chrome plating and heat treatment, ensuring millions of cycles of wear resistance.
