High Speed CZ Purlin Cold Roll Forming Line with PLC Control 0-20m/min

What is CZ steel cold bending production line?

The CZ steel cold bending production line is a highly integrated automated cold bending equipment, dedicated to producing C-shaped steel and Z-shaped steel purlins in steel structure buildings. The entire production line is unified and coordinated through a PLC control system, which can achieve the full process automation of continuous unwinding, leveling, punching, roll forming, cutting to length, and receiving of steel coils.

The standard production process is: hydraulic unwinding → leveling and feeding → punching → roll forming → hydraulic cutting → automatic feeding. The operator only needs to set the specifications, length, hole spacing and other parameters of the purlin on the touch screen, and the entire production line can run automatically.

Core Advantages:

1. High speed and efficiency, doubling production capacity
2. CZ exchange, worry free replacement of models
3. Intelligent PLC control, easy to operate
4. High precision molding, stable quality
5. Knife free cutting, low maintenance cost

Application Areas:

The C-shaped steel and Z-shaped steel purlins produced by the CZ steel cold bending forming line are widely used in various steel structure building scenarios:

• Industrial buildings: Roof and wall purlin systems for steel structure factories, logistics warehouses, and manufacturing workshops

• Commercial buildings: Steel structure support systems for large supermarkets, sports arenas, and exhibition centers

• Agricultural buildings: roof support components for livestock farms and grain warehouses

• Prefabricated buildings: wall studs and roof purlins for light steel villas and modular houses

• Other uses: Cable trays, photovoltaic brackets, large storage shelves

Frequently Asked Questions (FAQ):

Q1: How long does it take for CZ exchange on the CZ molding line?

CZ interchange is completed through PLC control or manual rotation of 180 degrees, usually taking only 1-5 minutes to switch between C-shaped steel and Z-shaped steel, without the need to replace the forming rollers.

Q2: Does the device support infinite switching?

support. Within the set range, the dimensions of the web, flange, small edge, etc. can be adjusted in millimeters, and different specifications of purlins can be produced without replacing the forming rollers, as well as non-standard products.

Q3: Does the cutting system require frequent tool changes?

No need. The equipment adopts a formed infinite cutting system, and one tool can cover the entire specification range of 80-300mm. The cutting process does not require blade replacement, greatly reducing maintenance costs and downtime.

Q4: What voltage and power standards does the device support?

The equipment can be customized with voltage configuration according to the power grid standards of the customer's country, supporting different voltages such as 380V, 415V, 440V, etc. The frequency can be selected as 50Hz or 60Hz, and it is a three-phase power supply.
