The Metal Steel C Stud and Track System Drywall Roll Forming Machine is a fully automatic cold bending equipment designed specifically for metal coils such as galvanized steel strips and cold-rolled steel strips. It integrates multiple processes such as unwinding, leveling, servo feeding, online punching, cold bending, cutting to length, and automatic palletizing into one production line, achieving continuous automation of the entire process from “steel coil in” to “finished product out”.

This production line can produce light steel keels for construction, including partition keels (Q50/Q75 series C-shaped vertical keels and U-shaped ground edge top keels) and ceiling keels (D38/D50 series main keels and auxiliary keels). Galvanized steel strips are rolled into various cross-sectional profiles such as C-shaped, U-shaped, T-shaped, etc. through cold bending technology. Some advanced models support the “one machine dual model” function, which allows for the simultaneous production of C-type and U-shaped keels without the need for adjustment. The entire line adopts PLC programmable controller and touch screen operation interface, supporting multi specification parameter storage and one click switching. It is the core equipment for light steel keel manufacturing enterprises to achieve large-scale, standardized, and intelligent production.

Scientific and rigorous process flow：

The fully automatic C-type/U-shaped light steel keel cold bending production line follows a standardized and systematic process flow:

Hydraulic unwinding and feeding → Multi roll leveling → Servo precise positioning feeding → Online punching (installation hole/connection hole) → Multi pass cold bending forming → Hydraulic cutting to length → Automatic discharge and palletizing

The entire process is interconnected and seamlessly connected. among which

1.Uncoiling unit: equipped with heavy-duty feeding rack, tension control, and automatic correction device to ensure smooth unwinding without deviation;

2.Leveling unit: Multiple sets of high-precision leveling rollers are used to correct the wave patterns and warping of raw materials, ensuring a smooth surface after the formation of the keel;

3.Punching unit: using a hydraulic punching system to complete high-precision punching of installation holes, connection holes, and other hole positions;

4.Forming host: Core component, designed with multiple forming rolls according to C-shaped or U-shaped cross-sections, gradually rolled into shape through cold bending process;

5.Cutting unit: using hydraulic tracking cutting technology, the incision is smooth without burrs, and the cutting accuracy is ± 0.1mm.

The final finished keel has excellent qualities such as precise size, smooth surface, and reliable strength, and can be directly used for on-site installation of various partition walls and ceiling projects.

Widely applicable scenarios：

The keel products produced by the fully automatic C-type/U-shaped light steel keel cold bending production line are widely used in the following fields:

• Indoor partition wall system:
The combination of C-shaped vertical keel and U-shaped along the ground and top keel forms a light steel keel partition wall frame, which is widely used in indoor non load bearing partitions of office buildings, hotels, residences, hospitals, schools, commercial complexes and other buildings;

• Ceiling system:
D38/D50 series main and auxiliary keels form a light steel keel ceiling skeleton, suitable for decorative materials such as mineral wool board, gypsum board, aluminum buckle board, etc;

• Light steel structure buildings:
used as key structural materials in light steel villas, modular houses, and prefabricated buildings to construct wall frames and support structures;

• Industrial and public facilities:
places with high requirements for fire prevention, sound insulation, and earthquake resistance, such as factory workshops, data centers, hospitals, airport terminals, etc;

• Old house renovation and fine decoration:
With the implementation of fine decoration policies and the increasing demand for old house renovation, the application of light steel keel in the field of residential decoration has grown significantly.

Core advantage: Five dimensions define new industry benchmarks

1. High efficiency production capacity and exponential leap in production efficiency
Modern high-speed keel machines can operate stably at a speed of 30 to 50 meters per minute, and some high-end models can even reach 40 to 100 meters per minute. Compared to the traditional low-speed production process of 6 to 10 meters per minute, the increase in production capacity is as high as 5 to 10 times. By cooperating with the automatic coil changing device, non-stop feeding can be achieved, and the daily production capacity of a single production line can easily exceed 10000 to 20000 meters, which is sufficient to meet the centralized supply needs of multiple large construction sites in the region. From “reducing personnel” to “improving quality”, high-speed keel machines are fundamentally changing the production mode and competitive landscape of small and medium-sized building materials factories.

2. Precision molding, stable and reliable quality
The production line adopts a multi pass progressive cold bending process, which precisely shapes the sheet metal into keel profiles through precision rollers. The forming roller is made of high-quality bearing steel material, combined with precision grinding and hard chrome coating treatment. The entire line is equipped with a high-precision servo control system and PLC closed-loop control, with a dimensional accuracy of ± 0.1mm and a straightness error controlled within ± 0.2mm, far exceeding the tolerance level of traditional semi-automatic equipment of ± 0.25mm.

3. Flexible changeover, versatile and efficient for one machine
In traditional production methods, switching between different specifications of keels often requires several hours to replace rollers and molds. Modern high-speed keel machines adopt fast roll changing or servo adjustable roll structures, greatly reducing the changeover time from traditional hours to 15 to 30 minutes. Some high-end models even support automatic adjustment of width and height through servo motors, and the changeover time can be shortened to less than 20 minutes, truly realizing the flexible production of “one machine for multiple uses”. Operators can store over 200 preset configuration parameters through the touch screen, which can be easily accessed with just one click when switching between different specifications, greatly improving the flexibility of production scheduling and equipment utilization.

4. Intelligent control, worry free production process
The production line is equipped with a PLC intelligent control system and a touch screen human-machine interface. Operators can set key parameters such as keel specifications, length, and speed through the touch screen. The system supports multi specification parameter storage and one click calling, and also has real-time monitoring and fault diagnosis functions. It can monitor variables such as vibration, temperature, pressure, etc. during operation through IoT sensors, detect and warn of abnormalities in a timely manner. The system supports both automatic and manual operation modes, enabling linkage and segmented operation, providing great convenience and safety guarantee for production management.

5. Cost reduction and efficiency improvement, short investment return cycle
Automated production significantly reduces the demand for manual labor – traditional production lines require 3 to 5 skilled workers to work together, while automated production lines only require 1 to 2 people to be responsible for loading, inspection, and packaging. Calculated based on an annual cost of 60000 to 80000 yuan per person, labor costs can be saved by 200000 to 300000 yuan per year, and equipment investment can be recovered within 1 to 2 years.
