introduction

The C Profile Universal Shaft Adjustable Roll Forming Machine is a highly versatile and intelligent cold-forming device, specially engineered for producing C-shaped steel profiles—a kind of lightweight, high-strength structural component widely used in construction, machinery manufacturing, and photovoltaic support systems. What distinguishes this machine from conventional models is its universal shaft adjustable structure, which allows flexible adjustment of forming parameters without frequent die replacement, greatly improving production flexibility and reducing downtime.

C Profile Roll Forming Machine Advantages

1. Strong Versatility with Universal Shaft Design: The core advantage lies in the universal shaft adjustment system. It can produce C-profiles of various specifications by simply adjusting the roller parameters, which is 3–5 times faster than the traditional die-replacement method.

2. High Forming Precision & Stability: Equipped with hardened alloy steel rollers and a servo positioning system, the machine ensures consistent cross-sectional dimensions of C-profiles, with a linearity error ≤ 0.5mm/m and a length tolerance ≤ ±1mm, meeting national and international industry standards .

Intelligent & User-Friendly Operation: Integrated with a PLC control system and a touch screen interface, the machine allows one-key setting of production parameters (profile size, cutting length, speed). It also has real-time fault diagnosis and alarm functions, reducing the difficulty of operation and the requirement for professional technicians.

3. High Production Efficiency: The continuous production mode achieves a speed of 8–25m/min. The adjustable structure eliminates the time-consuming die replacement process, which is especially suitable for small-batch and multi-specification production scenarios.

4. Durable & Low Maintenance: The main frame is made of welded high-strength steel and undergoes stress relief treatment, with strong rigidity and no deformation during long-term operation. The key components (bearings, motors, reducers) are of well-known brands, reducing the frequency of maintenance and extending the service life of the equipment.

Production process:

The production line is carried out according to the following technological process:
Uncoiler → leveler → looper (material storage)→ servo feeding → multi-station punching machine (cut off)→ molding main machine → finished product discharge

1.Uncoiling:
The machine is in single-head mode, single support and manual tightening.

2. Servo Leveling Feeder:
The machine adopts 5 rollers for leveling and feeding (2 rollers on the upper layer, 3 rollers on the lower layer, screw adjustment), 1 pair of guide rollers, the feeding rollers are pneumatically clamped, and the servo motor provides power for it.

3. Roll Forming Machine
Used to achieve the final required shape through the roll forming process of the required finished plate. The material is made of high-quality mold steel Cr12, and the hardness after quenching reaches HRC58~62 (physical characteristics are equivalent to American material D2), which improves mechanical performance and life. The surface of the roller is polished after finishing. The roller has high precision and long life.

Uncoiler and leveler

Uncoiler: This machine is single head mode (single support, four-bar tensioning structure, tensioning force comes from hydraulic cylinder, fast and reliable adjustment. The uncoiler is an automatic uncoiler with pneumatic pressing device. When the material coil is installed on the material shaft of the uncoiler, the material shaft of the uncoiler rotates automatically during the actual operation of the whole line, and the working speed of the uncoiler can be adjusted according to the operation of the whole line. In order to ensure the actual safety of the uncoiler, the uncoiler is equipped with pneumatic brake device.
