Processing Technology and Installation Points
Hyperbolic aluminum panels are prefabricated panels that need to be pre-formed in the factory and then assembled on-site according to drawings. Therefore, hyperbolic aluminum panels require high precision in factory prefabrication.
1. Processing Technology
Common processing and forming methods for hyperbolic aluminum panels include die stretching forming, forming using a multi-point forming press, one-time stamping forming with a mechanical metal mold, flexible roll forming, and on-site forming.
① Die Stretching Forming
This is the most common method for processing hyperbolic metal panels. First, a mold is carefully made according to the specific design requirements; then, the aluminum panel is firmly stretched and fixed to this mold using rubber. Subsequently, workers carefully tap the aluminum panel to ensure it fits tightly to the mold surface. After the internal stress of the aluminum sheet is fully released, the edges and corners are trimmed to remove excess or irregular parts, ultimately obtaining a curved aluminum sheet that perfectly matches the design requirements.
The fixing mold is usually made of wood, plastic, steel, etc. The characteristics of mold stretching forming are suitable for forming large batches of aluminum sheets with the same curvature. It offers fast forming speed and high precision. The disadvantage is the high cost of mold manufacturing, making it unsuitable for small batches of diverse curved metal parts.
② Multi-point Forming Press Forming
This mold consists of discrete points whose positions are adjustable, allowing for mold reuse and small product errors. However, it is costly and suitable for small batch production.
③ One-time Stamping Forming with Mechanical Metal Molds
Metal molds are generally divided into upper and lower molds. They are formed in one step using machine tool hydraulics. One-time mold manufacturing allows for mass production, but the limitations of mold manufacturing cycle and cost make it unsuitable for small batches of irregularly shaped parts.
Multi-point forming mold technology has also been introduced into the machine tool mold field. This technology can form complex curved metal sheets in one step and is more flexible in terms of batch and quantity requirements. By importing the design model into a computer, a fully automated production process can be quickly achieved, ensuring high product precision. However, due to the high cost of multi-point forming machine tools, they are currently relatively rare in China.
④ Flexible Roll Forming
Its significant feature lies in the bending capability of the work roll axis, and this bending shape can be precisely controlled and adjusted according to actual needs. During the forming process, the sheet material to be processed is tightly clamped between the work rolls, which rotate synchronously under the drive mechanism, driving the workpiece to feed. This process causes the work rolls to roll the sheet material, resulting in plastic deformation in both the longitudinal and transverse directions, making it suitable for forming aluminum sheets with various complex curved surfaces. However, the equipment cost for this technology is high, and the maintenance and adjustment of the equipment also incur significant expenses.
⑤ On-Site Forming
On-site forming technology is particularly suitable for producing aluminum single panels with large radii. First, the back rib data is accurately calculated using specialized software, and based on this, the hanging point positions of each aluminum sheet are precisely located. Next, steel reinforcement joists are installed to support the back reinforcement structure, and curved aluminum tubes are set at key nodes as reference "line rulers." Then, construction workers adjust and fix the aluminum plates according to the "line rulers," ensuring a tight fit. This method significantly reduces manufacturing costs, but correspondingly, it places extremely high demands on the installation quality during on-site construction.
