In the field of modern building construction, the application of various machinery and equipment has greatly improved the construction efficiency and quality. Among them, the CU keel opening and closing keel machine has gradually become one of the indispensable equipment in the construction industry due to its unique functions and advantages. The working principle of the CU keel is based on cold-formed forming technology. First of all, the coils of metal plates, such as galvanized steel plates, color steel plates, etc., are placed on the unloading rack of the equipment. The unloading frame is driven by a motor, which can accurately control the feeding speed and tension of the plate to ensure that the plate enters the main machine part smoothly. The main engine part is the heart of the keel machine, which consists of a series of elaborate rolls inside. These rolls are precisely machined and mounted according to the shape requirements of the CU keel. When the plate enters the main machine, it goes through the rolling action of multiple groups of rolls in turn. Each group of rolls is responsible for a specific forming task, and the flat sheet is gradually cold-formed into the shape of a CU-shaped keel according to the preset arc and size. In order to ensure the accuracy and quality of the keel during the forming process, the equipment is equipped with high-precision guides and positioning systems. The guide ensures that the sheet always maintains the correct direction of travel during the rolling process, avoiding deviation or twisting; The positioning system can accurately control the length of the keel according to the preset size, and when the keel reaches the set length, the shearing device will be quickly activated to cut the formed keel and complete a production cycle.

Structural Design Highlights：
1.Rugged frame:
The frame of the CU keel machine is welded from high-strength steel and undergoes a rigorous heat treatment process to provide excellent stability and load capacity. Even during long, high-intensity production operations, the frame remains stable and provides a solid foundation for the normal operation of the equipment.
2.High-precision roll system:
As a key component that determines the quality of keel forming, the roll is made of high-quality alloy steel, and undergoes precision processing and heat treatment. The surface of the roll is chrome-plated, which not only improves the hardness and wear resistance, but also makes the formed keel surface smoother, reducing scratches and blemishes. At the same time, the design of the rolls adopts a modular concept, which makes it easy to install and debug quickly and easily when different types of dies need to be replaced.
3.Advanced transmission and control system:
The transmission system of the equipment adopts a combination of motor and reducer, and transmits power to each roll and working parts accurately through chain or gear transmission. This transmission mode has the advantages of high transmission efficiency, stable operation and low noise. The control system adopts advanced PLC programmable controller, the operator only needs to input the required keel specifications, production speed and other parameters on the operation panel, and the equipment can automatically complete the entire production process, achieve a high degree of automatic control, and greatly improve the production efficiency and product consistency.
4.Convenient shearing and discharging device:
The shearing device adopts hydraulic drive or mechanical drive, and the cutter is made of special alloy material, which has the characteristics of sharp and durable, large shear force, and can quickly and accurately cut the formed keel. The discharging device is designed as a conveyor frame with adjustable height and angle, which is convenient for conveying the severed keel to the designated position, which is convenient for subsequent handling and stacking.
The performance benefits are highlighted：
1.Efficient production:
The CU keel opening and closing machine has a high production speed of 15 – 30 meters per minute, which can meet the construction needs of large-scale construction projects. The highly automated production process reduces manual intervention, which not only improves production efficiency, but also reduces labor costs and labor intensity.
2.High-precision products:
Through advanced control system and precise mechanical structure, the equipment can ensure that the produced CU-type keel has high dimensional accuracy and the error is controlled within a very small range. The flatness and consistency of the keel can reach the industry-leading level, providing high-quality material guarantee for building construction.
3.Strong versatility:
The equipment has good versatility, and can produce a variety of sizes and models of CU keels by replacing molds of different specifications to meet different architectural design and construction requirements. Whether it is a lightweight keel for interior partition walls and suspended ceilings, or a heavy-duty keel for large buildings such as industrial plants and warehouses, it can be easily handled.
4.Stability and reliability:
In the design and manufacturing process of the equipment, the stability and reliability of long-term operation are fully considered. The selection of high-quality parts, after strict quality inspection and debugging, to ensure that the equipment can operate stably in a complex working environment, reduce the probability of failure, reduce maintenance costs.
