Octagonal Steel Tube Roll Forming Machine

Equipment Profile

Engineered for continuous industrial output, this Octagonal Steel Tube Roll Forming Machine is the definitive solution for fabricating heavy-duty roller shutter door axles, advanced garage door systems, and specialized automotive or motorcycle accessories. The heavy-duty H450 steel body frame provides a solid, vibration-free foundation, ensuring that every octagonal tube emerges with absolute dimensional accuracy. Operators will immediately notice the smooth, quiet operation of the precision-machined gear and chain drive system. Coated in a highly visible industrial blue, black, and orange finish, the equipment not only looks professional on the factory floor but also resists daily wear and tear. By integrating advanced 3D forming simulation during the design phase, the machine guarantees a flawless, scratch-free surface on every galvanized steel coil processed, meeting the strict aesthetic and structural demands of modern construction projects.

Product Description

Versatility and safety are at the core of this forming line. Recognizing that project requirements fluctuate, this machine offers exceptional compatibility and customization capabilities. Through a highly efficient cassette-style tooling exchange system, a single production line can be rapidly reconfigured to manufacture multiple octagonal tube sizes—including 40mm, 60mm, and 70mm profiles. This flexibility drastically improves the return on investment for manufacturing facilities, eliminating the need to purchase separate machines for different specifications.

Furthermore, the entire system is built to international CE standards, featuring comprehensive protective covers over all transmission components and strategically placed emergency alarm stop mechanisms to ensure complete operator safety on the factory floor. The structural integrity is guaranteed by a heavy-duty H450 steel frame, which absorbs operational vibrations and maintains alignment over years of continuous use. The table below outlines the exact technical specifications that drive this dependable production unit.

Operational Work Flow

The production sequence is engineered for fluid, uninterrupted material handling. From the initial coil feeding to the final stacking, each stage is synchronized to eliminate bottlenecks and reduce material waste. The process begins at the de-coiler, where galvanized steel coils are smoothly unwound. The material then passes through a precision leveling device, ensuring perfect flatness before entering the pre-punching station. Here, necessary holes are stamped with exact spacing. The core transformation occurs in the roll forming mill, where 20 solid forming stands progressively shape the flat steel into a perfect octagonal profile. Once formed, the pneumatic saw slices the tube to the exact length programmed in the PLC control system, leaving a clean, burr-free edge. Finally, the finished octagonal tubes slide onto the exit rack, ready for immediate packaging or assembly into roller shutter doors.

Machine Components

1. Manual De-coiler: one set

Capacity: MAX.3Tons; Feeding width: Max. 600mm, coil ID range 508±30 mm

To accommodate diverse budget constraints and automation requirements, buyers can select between this reliable manual de-coiler or upgrade to a fully hydraulic version. Both options ensure stable coil feeding without jerking, protecting the surface integrity of the raw material.

2. Leveling Device and Pre-punching device

Up four down three total seven roll straightening device. Stop to punching.

This section flattens the galvanized steel with immense pressure, removing coil set and ensuring the material enters the forming section perfectly straight. The pre-punching unit operates with crisp precision, leaving clean hole edges ready for immediate assembly.

3. Cold Rolling Mills

With feeding material guide, body frame made from H450 steel plate welding, milling/polishing. Side wall thickness: 18mm.

Rollers manufactured from 45#, CNC lathes, hard Chrome Coated; Shafts Diameter=φ75mm, precision machined. Gear & chain drive, 20 steps to form. Main motor=11KW, Frequency speed control.

Forming speed: Approx. 6m/min.

All the screw bolts with grade 8.8 (cheap factories use low grade 4.8) to ensure fix the machine structure tightly and long life during the machine long time running.

The core craftsmanship shines here. Every roller undergoes rigorous precision grinding and is treated with a 0.05mm hard chrome plating, ensuring maximum wear resistance and zero damage to the galvanized coating. Optional gear or chain drive systems are available to match specific torque requirements.

4. Pneumatic Saw Cutting device

With Saw Cutting Device; Stop to cut; Cutting Blade Material: high speed steel cutting blade. Performance guarantee: Cutting should be smooth after adjustment.

Buyers can choose between standard hydraulic cutting or a high-speed flying saw configuration. The high-speed steel blade slices through the octagonal profile with a distinct, sharp sound, leaving a burr-free edge that requires no secondary finishing.

5. PLC Control System

Control the quantity, cutting length automatically. Combined With: PLC, Inverter, Touch Screen, Encoder, etc.

PLC: Delta(TAIWAN brand) | Inverter: Delta(TAIWAN brand) | Touch Screen: WEINVIEW(TAIWAN brand) | Encoder: Omron (Japan brand) | Switch Bottom, Indicate Light, Power Supply, Intermediate Relay, AC Contactor, Thermal Relay: Schneider Electric(France brand) | Air Switch: LG-LS(Korea brand).

Cut-to-Length Tolerance≤±1 mm. Control Voltage 24V.

Operating this complex machinery is remarkably straightforward. The highly integrated PLC touch screen allows for instant length and batch adjustments. Furthermore, the machine is equipped with digitally marked handwheels and adjustment scales, drastically lowering the learning curve for new operators and reducing profile changeover times to mere minutes.

6. Exit Rack

un-powered, 2 units.

The standard un-powered run-out tables safely catch the finished tubes. For higher volume operations, an automated stacking system can be integrated as an optional upgrade, further reducing manual labor.

Packaging & Shipping

Packing method: Main body of machine is naked and covered by plastic film (to protect of dust and corrosion), loaded into container and steadily fixed in container suitable by steel rope and lock, suitable for long-distance transportation.

We understand that international logistics require rigorous preparation to ensure your investment arrives in pristine condition. Before wrapping, all exposed metal surfaces of the main machine body are meticulously coated with industrial-grade anti-rust oil. The entire equipment is then tightly covered by thick, durable plastic film to protect against dust, moisture, and corrosive salt air during ocean transit. Once loaded into the shipping container, the heavy-duty H450 steel frame is steadily anchored to the container floor using high-strength steel wire ropes and specialized locking mechanisms. This comprehensive packing method completely neutralizes the rolling and pitching motions of long-distance transportation, guaranteeing that the roll forming line will be ready for immediate installation and testing the moment it reaches your facility.
