The C/Z-shaped steel integrated machine is a specialized fully automatic cold bending equipment for the steel structure industry. It can quickly switch between producing two main types of purlin profiles, C-shaped steel and Z-shaped steel. It integrates functions such as unwinding, leveling, punching, forming, cutting, and discharging, with high automation and strong versatility. The output profile has precise dimensions and reliable strength, mainly used as load-bearing purlins for roofs and walls of steel structure factories, venues, photovoltaic power stations and other buildings. It is the main equipment for processing steel structure matching profiles.

Equipment structure composition

• Hydraulic unwinding machine: The hydraulic tensioning structure fixes the steel coil and is equipped with a pneumatic brake device to ensure uniform and stable feeding, effectively preventing the plate from deviating.
• Precision leveling mechanism: Multiple sets of leveling rollers correct plate deformation, eliminate internal stress, ensure smooth feeding, and lay the foundation for subsequent forming.
• Servo punching unit: hydraulic punching system, can process connection holes and installation holes as needed, with standard hole positions and burr free cutting surfaces, meeting assembly requirements.
• C/Z Switching Forming Host: Equipped with a roll group structure that can be quickly switched, it can complete the conversion of C and Z steel plate types without the need to disassemble the mold as a whole. Multiple rolling rolls are gradually cold-formed, and the profile section is regular and the straightness is excellent.
• Hydraulic flying shear cutting mechanism: Cr12MoV wear-resistant cutting tools are used, followed by fixed length cutting, with a smooth cut and no deformation or warping of the profile ports.
• PLC intelligent control system: touch screen human-machine interface, supports parameter storage, automatic length measurement, production counting, fault self checking alarm, simple and convenient operation.
• Finished product discharge rack: automatically accepts and stacks profiles to avoid surface scratches and bumps, making it convenient for transportation and storage.

Core advantages

• One machine dual-use, outstanding cost-effectiveness: a single device can produce two types of purlins, C and Z, with fast switching of plate types, reducing equipment procurement costs and site occupation, and adapting to diversified production orders.
• Heavy duty and durable, suitable for continuous operation: The heavy-duty body and reinforced transmission components can withstand long-term processing of thick plates, with stable operation, low vibration, and low failure rate.
• High forming accuracy and good assembly: The cold bending process is mature, with small errors in the shape, aperture, and length of the profiles. The finished products are tightly spliced and fully comply with the steel structure installation standards.
• High degree of automation, saving manpower: The entire line operates automatically, requiring only one person to be on duty, significantly increasing production capacity and reducing labor input.
• Good protection: The rollers are treated with special technology, and when processing galvanized, zinc aluminum magnesium sheets, they will not scratch the surface anti-corrosion layer, extending the outdoor service life of the profiles.

Performance characteristics

• Variable frequency speed regulation, low operating noise, controllable energy consumption, and flexible speed adjustment according to production conditions.
• The pattern switching process is simple, and skilled personnel can complete specification changes in a short period of time, resulting in efficient production connection.
• The standardization level of components is high, and the replacement of vulnerable parts is convenient. Regular lubrication and maintenance are only required, resulting in low maintenance costs.
• Wide processing range, covering mainstream purlin specifications in fields such as construction and photovoltaics, with strong universality.

Application scope

• Steel structure buildings: Processing of load-bearing purlins on roofs and walls of buildings such as factories, warehouses, exhibition halls, and sports halls.
• Photovoltaic engineering: production of support profiles for ground photovoltaic power stations, roof distributed photovoltaics, and agricultural/fishery complementary projects.
• Supporting projects: production of lightweight steel structural profiles such as greenhouses, steel structure enclosures, and continuous span workshops.
• Professional processing plants: large-scale steel structure enterprises and profile processing plants produce standardized batches.
