Automatic Container Corner Post Roll Forming Machine

Against the backdrop of rapid development in global container manufacturing and modular construction industries, corner columns, as the core load-bearing structural components of containers and assembly houses, directly determine the structural safety of products and the delivery capability of manufacturing enterprises in terms of molding quality and production efficiency. The Automatic Container Corner Post Roll Forming Machine, as the core equipment for producing container corner columns and container room columns, is helping container manufacturers and modular construction enterprises achieve dual breakthroughs in production capacity and quality with its fully automated control, high-precision forming, and stable mass production capabilities.

What is a container corner column forming machine?

The container corner post forming machine is a fully automatic cold bending production line, dedicated to gradually rolling galvanized steel coils or high-strength steel coils through multiple precision arranged rollers to form the corner post and upright column components required for containers.

Container corner columns are the four core load-bearing columns of containers, responsible for the mechanical requirements of lifting, stacking, and maritime fastening, and must meet the strict tolerance range of ISO container standards. Container room corner columns are used for the frame structure of temporary office rooms, emergency resettlement rooms, and mobile homestays in modular buildings, requiring quick assembly and stable load-bearing.

The equipment usually consists of a hydraulic unwinding machine, a leveling feeding device, a pre punching unit, a cold bending forming host, a hydraulic shearing system, and a PLC control system, etc., to achieve fully automated production from coil feeding to finished corner column output. The standard production process is: uncoiling → leveling → pre punching → roll forming → fixed length cutting → finished product output.

Core Advantages：

1.Fully automatic PLC control, efficient production
The equipment is equipped with an industrial grade PLC control system (optional brands such as Delta, Siemens, Panasonic, etc.) and a touch screen human-machine interface, supporting automatic length setting, batch counting, and real-time production data display. The operator only needs to input parameters such as corner column length and production quantity, and the system can automatically complete the full process control of forming and cutting. In fully automatic operation mode, only 1-2 operators are needed to complete production line management.

2. High precision molding, stable quality
The equipment adopts multiple guarantee measures in precision control. The rolling mill is made of GCr15 bearing steel, which has a hardness of HRC58-62 after quenching treatment. Combined with precision machining and hard chrome plating treatment, it ensures precise and wear-resistant forming contours. The molding process is usually 18 passes, which gradually deforms the sheet and evenly distributes stress. The cutting tool is made of Cr12MoV material, with a smooth and burr free cut, and the cutting tolerance can be controlled within ± 1mm. The PLC numerical control system is equipped with encoder counting, and the pressure control accuracy can reach ± 1% FS.

3.Strong load-bearing capacity, meeting strict standards
The column components produced by the container corner column forming machine have complex cross-sections and high structural strength, which can meet the lifting, stacking, and maritime fastening requirements of ISO container standards. The equipment can process galvanized steel, high-strength steel, stainless steel, aluminum alloy and other materials with a thickness of 1.5-3mm, suitable for standard sea freight containers and container houses used in harsh environments.

4. Flexible customization, widely adaptable
The equipment supports customizing roll molds based on customer provided corner column cross-sectional drawings, and can produce various specifications of container corner columns and assembly room columns. Some models can integrate online processing functions such as punching, chamfering, and reinforcing ribs, completing multiple processes at once. The equipment can be used in conjunction with top and bottom beam forming machines to form a complete container steel structure production line.

6. Durable and sturdy, stable and reliable
The formed main frame adopts a 400 # H-beam welded structure, which undergoes stress relief treatment and precision machining to ensure stability during long-term operation. The main shaft adopts a large diameter solid shaft (80mm), coupled with a gearbox transmission system, to ensure stable output under high-intensity continuous operation. The hydraulic system is equipped with an oil cooling device, which can maintain low temperature stability during long-term continuous operation.
