Introduction to CU type steel machine foundation：

CU type steel machine is mainly used for processing and producing C80-300 type steel and U80-300 type steel (purlins), with a suitable material thickness range of 1.0-3.0mm. Its forming process can reach up to 20 passes, and through precise cold bending forming processes, it ensures that the steel has a stable structure. The forming speed of the equipment can reach 18 meters per minute, driven by a variable frequency speed regulating motor with a power of 18.5KW, and adopting a gear chain transmission method, ensuring the efficient and stable operation of the equipment, while also making energy utilization more reasonable. ​
In the feed guidance stage, positioning rollers are equipped to flexibly adjust the positions of both ends, accurately adapting to different widths of feed, so that materials can smoothly enter the processing flow; The guide roller adopts an upper and lower circular roller design, greatly optimizing the feeding process, reducing the occurrence of jamming, and avoiding material damage. In addition, the wall panel tie rod is made of φ 20 # electroplated round steel, which enhances the rigidity on both sides of the wall panel and further ensures the stability of the feeding. ​
In terms of roller shaft components, the main shaft diameter is up to 75/90mm, and high-quality 45 # round steel is selected to provide strong support and stability to the equipment. After precision machining, the rollers are plated with hard chrome and then subjected to mirror polishing and heat treatment. This not only improves the surface hardness and extends the service life, but also makes the cold bending process smoother, effectively improving the surface quality of the product. The base rod is also made of φ 20 # electroplated round steel, further increasing the rigidity on both sides of the wall panel to ensure the overall smooth operation of the equipment. ​
After forming, the cutting part adopts a guide mechanism of upper and lower guide rail cutting device, which can ensure that the incision is flat and not deformed. The cast iron tool holder has good shock absorption and impact resistance, and can withstand high-intensity working loads. The blade is made of Cr12Markov material and undergoes heat treatment, with a shear life of over 1 million times, greatly reducing the frequency and cost of tool replacement. The rear scissor frame is made of Q235 steel plate, which undergoes rough milling, annealing treatment, and precision machining to ensure cutting accuracy and long-term stable operation of the equipment. ​

CU type steel machine application field：

1.Construction industry
（1）Building construction:
In various civil buildings such as residential and office buildings, C-shaped and U-shaped steel (purlins) produced by CU steel machines play an important role in structural support. As the framework structure of the roof and walls, they can effectively distribute the weight of the roof and walls, transfer the load to the main load-bearing structure of the building, and ensure the stability and safety of the house. For example, in prefabricated residential construction, standardized production of C and U-shaped steel components can be quickly assembled, greatly shortening the construction period. ​
（2）Factory building:
For large factory buildings, C and U-shaped steel are often used to construct the beams and wall beams of the building. Its good load-bearing capacity and stability can meet the construction needs of large spaces and spans in factories, while also reducing the overall weight of factories and lowering infrastructure costs. Moreover, the surface of C and U-shaped steel is flat and of uniform specifications, which facilitates subsequent wall and roof installation and construction. ​
2.Other industrial sectors
（1）Storage shelves: In the logistics and warehousing industry, the steel produced by CU type steel machines can be used to manufacture various types of storage shelves. The high strength and good processability of C-shaped and U-shaped steel enable shelves to withstand the storage of heavier goods, and can flexibly design and assemble shelf structures according to different storage needs, improving the utilization of storage space. ​
（2）Equipment frame:
In the field of mechanical equipment manufacturing, many equipment frame structures are made of C and U-shaped steel. These steel sections can provide stable support for equipment, and due to their ease of processing and connection, they facilitate the installation of various components on the frame, achieving functional integration of the equipment. ​

The advantages of CU type steel machine are fully demonstrated：

1.Efficient production capacity
The molding speed of 18 meters per minute, combined with automated production processes, can significantly improve production efficiency. Compared with traditional profile processing methods, CU steel machines can produce a large number of C-shaped and U-shaped steel products in a shorter period of time, meeting the supply needs of large-scale projects, effectively shortening project construction cycles, and creating greater economic benefits for enterprises. ​
2.Excellent product quality
（1）High precision machining:
Through 20 forming processes and precise equipment calibration, it can ensure that the produced steel has high dimensional accuracy, with errors controlled within a very small range, meeting the strict requirements for profile accuracy in various construction and industrial projects. ​
（2）Good structural performance:
After multiple cold bending processes, the internal structure of the steel section becomes denser, with higher strength and stability, and can withstand large loads in practical applications, ensuring structural safety. ​
（3）High quality surface quality:
The special treatment of the rollers and advanced processing technology make the surface of the steel section smooth and flat, without obvious scratches, wrinkles and other defects, which not only improves the beauty of the product, but also reduces the workload of subsequent surface treatment processes. ​
3.Intelligent operation and maintenance
（1）Intelligent control system:
equipped with Delta/Schneider high-precision PLC electrical control system, combined with Schneider heavy-duty frequency converter, operates efficiently and stably. Through touch screen operation, operators only need to input production data, and the equipment can automatically complete production tasks, achieving intelligent and automated production. This not only reduces human operational errors and improves the consistency of product quality, but also lowers the requirements for the professional skills of operators, making it easier for enterprises to quickly get started and use. ​
（2）Stable and reliable operation:
The main control components of the equipment are all Schneider Electric, with a long service life and low failure rate. At the same time, the durability and stability of each component are fully considered in the design and manufacturing process of the equipment. Through strict quality testing, it ensures stable operation in long-term, high-intensity working environments, reduces equipment downtime for maintenance, and improves production continuity. ​
（3）Convenient maintenance:
The modular design of the equipment makes it easy to disassemble and replace various components, making daily maintenance work more convenient. At the same time, we also provide our customers with a professional after-sales service team, 7 days x 24 hours technical support and engineer services, to promptly solve any problems encountered by customers during equipment use and ensure the efficient operation of the equipment. ​
