To meet the growing demands of lightweight and high-strength automotive components, Zhongtuo Cold Bending Equipment Co., Ltd. has introduced its latest Caravan Z Beam Profile Rolling Forming Machine, a high-precision automated production line engineered specifically for caravan and commercial vehicle support frame systems.
Advanced Cold Roll Forming for Z-Beam Structures
This state-of-the-art forming machine transforms Q355B steel coils into accurately shaped Z-beam profiles through a fully automated process that includes decoiling, flattening, servo feeding, hydraulic punching, multi-pass roll forming, and precise hydraulic cutting. Designed to handle materials up to 3.0mm in thickness, it delivers both structural rigidity and dimensional accuracy essential for caravan subframe production.
Key Technical Highlights
Material Capability: Supports Q355B grade steel up to 3.0mm thick
Forming Speed: Operates at 6–8 meters per minute for standard profiles
Roll Forming Stations: 14 forming stations with additional calibration rollers ensure straightness and stability
Main Shaft Diameter: 75mm, hardened and precision-ground for long service life
Punching System: Integrated hydraulic system with 7 punching stations and 12 die sets, ensuring clean and consistent hole patterns
Cutting System: Hydraulic stop-to-cut method with high-durability H13 steel blades
Each stage of the machine—from decoiling to cutting—is PLC-controlled via Siemens interface with MCGS touch panel and equipped with international-standard components like Yaskawa inverters and Schneider electrical elements, ensuring performance stability and easy operation.
Intelligent Design for Seamless Production
What sets this Caravan Z beam machine apart is its fully synchronized production logic, powered by servo motors and hydraulic controls, allowing high throughput with minimal operator intervention. The roll forming system incorporates gear box-driven side frames with precision CNC-machined bases, offering unmatched alignment and low noise operation.
To maintain geometric accuracy, the forming rollers are CNC-processed from Cr12MoV steel, induction hardened to HRC 58–62, and paired with thick-wall bushings to minimize radial runout. The result is a Z-beam profile with exceptional straightness, angle consistency, and load-bearing performance—ideal for vehicle chassis and wall-support applications.
Tailored for the Automotive and Caravan Industry
Zhongtuo’s Caravan Z beam forming solution is purpose-built for trailer manufacturers, RV producers, and industrial vehicle frame fabricators. Whether you require a standardized Z profile or a custom beam geometry, the line can be adjusted according to your technical drawing and integrated seamlessly into your existing plant workflow.
The optional add-ons such as arc straightening devices, Turkish-style twist correctors, and pneumatic unloading racks provide manufacturers with full flexibility to meet different production scenarios.
