Hyperbolic aluminum veneer processing steps

The first is sheet metal processing. Sheet metal processing is mainly used to process the "general direction" of the appearance and size of the hyperbolic aluminum veneer aluminum veneer. The processing process is to cut the aluminum veneer into the structure required for cutting, folding, bending, welding, grinding and other processes. Shape and size, this part of the process determines important parameters, such as the curvature and appearance of the aluminum veneer. The second is spraying. Spraying is spraying on the finished aluminum plate. There are two types of spraying, one is manual spraying and the other is machine spraying. Machine spraying is generally only suitable for ordinary flat plates, but this type of aluminum veneer is rarely used in actual use, and most domestic manufacturers use manual spraying. One of the advantages of manual spraying is that the color can be selected regardless of size. The hyperboloid aluminum veneer needs to be pre-sprayed before spraying to obtain the best effect.
  
 
The forming process of the aluminum sheet metal component of the hyperbolic aluminum veneer from the blank to the finished product consists of multiple processes. The blank and nesting model of the blanking process, the workpiece model of the forming process and the springback correction model together constitute the manufacturing model. The accurate definition of manufacturing model is the basic basis for forming process and mold design, and controls the precise forming process of components. For sheet metal parts, it is necessary to consider factors such as part materials and deformation characteristics to establish special calculation tools for blanks and process models to provide data sources for tooling design, process parameter design, and CNC programming to meet the needs of precision forming of parts.

The aluminum sheet metal components used in the processing of hyperbolic aluminum veneers have low rigidity. The forming processes such as rubber bladder hydroforming, skin stretching, profile bending, duct bending, stamping and forming must be manufactured with a forming die that reflects the size and shape of the component To ensure the accuracy of its shape and size. The difficulty lies in the fact that in order to avoid forming defects (springback, wrinkles, cracks, etc.) and achieve precision forming, the shape of the mold is different from the shape of the finished product. Based on the manufacturing model, numerical simulation and other technical means are used to establish a comprehensive optimization technology for mold profile and size correction to ensure precise forming.
 

The aluminum sheet metal CNC forming equipment of the hyperbolic aluminum veneer processing plant has been widely used. Some key sheet metal forming equipment has adopted CNC, such as CNC blanking and milling, CNC drawing machine, CNC pipe bending machine, CNC bending Machine, CNC shot blasting machine, etc. The numerical control of aluminum sheet metal forming equipment has greatly improved production efficiency, accuracy and product adaptability compared with manual forming. For equipment such as skin stretching, shot peening, and numerical control stretching and bending, the main process parameters that need to be controlled are forming force, time and other process parameters. Traditionally, the control program is obtained by the "return-back" method that has been tested for many times. Improve processing efficiency and quality requirements. By analyzing the format of various equipment control program files, develop tools that automatically generate CNC instructions based on process parameters to realize the automation of CNC programming and the accurate control of equipment.

In this way, the price of hyperbolic aluminum veneer is fixed from 1500 yuan/square to the acceptable range of 450-800 yuan/square, which contributes to reducing the construction cost of modern hyperbolic buildings and adds luster to the beautiful Huaxia. Many people think that the curved aluminum veneer is nothing more than an aluminum veneer with a certain curvature. In fact, it is subdivided into: "single-curved aluminum veneer, hyperbolic aluminum veneer and spherical aluminum sheet, etc." The process is becoming more and more complicated. First, the overall arc calculation must be performed, and then laser seamless welding, polishing, etc. A curved surface, or a spherical shape, the entire processing process and the subsequent surface paint are very labor-intensive, so the cost is high. So, what are the differences between single-curve aluminum veneer and hyperbolic aluminum veneer?
