In modern architecture and manufacturing, steel structures have become a widely used structural form due to their advantages of high strength, light weight, and convenient construction. As an important component of steel structures, CZ steel plays a crucial role in supporting and connecting various types of buildings and industrial facilities. As the core equipment for producing CZ steel, the performance and technical level of CZ steel machines directly affect the quality and production efficiency of CZ steel, and play a crucial role in the development of the industry. ​

Working principle

The CZ steel machine mainly operates based on cold bending forming technology. After the equipment is started, the coiled steel strip is first smoothly unfolded by the unwinding machine and accurately fed into the leveling machine through the guiding device. The leveling machine uses multiple sets of rollers to apply pressure to the steel strip, eliminating the unevenness generated during rolling and transportation, ensuring that the steel strip enters the subsequent processing stage in a flat state. Subsequently, the steel strip enters the forming unit of the main engine. The host is the core component of the CZ steel machine, with multiple carefully designed sets of rollers arranged and combined according to the pre-set C-shaped or Z-shaped cross-sectional shape. When the steel strip passes through the forming unit, it gradually undergoes plastic deformation under the continuous cold bending action of the rolling mill, ultimately forming the required basic shape of CZ steel. To meet the diverse needs of different users for CZ steel specifications, some advanced CZ steel machines are also equipped with CNC systems. Operators can precisely adjust parameters such as roll spacing and angle through programming, achieving the production of CZ steel with different web heights, flange widths, and thicknesses. After completing the forming process, CZ steel will be transported to the cutting device. The cutting device precisely cuts continuous CZ steel according to the set length using high-speed cutting tools to obtain finished products that meet the size requirements. Throughout the entire production process, the automation control system monitors the real-time operation status of the equipment, such as the conveying speed, forming pressure, and cutting accuracy of the steel strip, to ensure the coordinated operation of each process and the stable and efficient production of high-quality CZ steel products. ​
