Processing Technology of Hyperbolic Aluminum Honeycomb Panel

Hyperbolic roof (curtain wall) because each plate is twisted or hyperbolic shaped plate. This isaluminum honeycomb panelProduction enterprises is a great challenge, through years of research and development and research, and finally successfully solved a variety of technical difficulties, to achieve the honeycomb panel hyperbolic, twisted industrial production. Formed a set of non-crease aluminum honeycomb panel processing molding technology, now the molding technology is introduced as follows.

(1)aluminum honeycomb panelThe three-dimensional model of the roof (curtain wall) system is deepened. The deepening process is to analyze and simulate each plate through a special computer design software to determine the processing and production method of each plate. Because all plates are distorted and large-scale mass production, it is necessary to classify and simulate the plates. The simulation method is to use the processing method of single curved plate to form the distortion effect. Specifically, each plate is placed at different positions on the single mold to form the position difference of four corner points, and then the actual three-dimensional model is used for comparison. If the position difference between the four corner points and the simulated four corner points and the middle two points is within ± 3mm, the processing method of single curved plate is adopted for processing; if it is greater than ± 3mm, it is necessary to use the processing form of the double curved plate. In addition, because the plate is twisted, the four sides will be arc edges when lofting is unfolded. The arc edges are the same for plates in different installation positions. Special design software is needed for lofting and unfolding to form a plane cutting processing diagram.

(2) the processing of honeycomb plate sheet metal

aluminum honeycomb panelAccording to the cutting processing drawing, the aluminum plate is numerically cut, and the numerical control turret is used for punching to ensure the processing dimensional accuracy of the plate within 2mm. After the cutting of the aluminum plate is completed, if the plate is hyperbolic, roll bending processing is required to eliminate the internal stress of the aluminum plate, prevent the rebound deformation of the composite forming hyperbolic honeycomb plate in the following sequence, and fold edge processing is performed after the cutting is completed. The main difficulty in the folding process is the processing of arc edges. On the basis of the flat and straight folding dies of the existing CNC bending machine, a special arc folding die with arch height has been successfully developed, and the die is adjustable arch height, thus solving the processing and production of arc edges.

(3) Composite molding

aluminum honeycomb panel复合成型就是把面铝、铝蜂窝、底铝通过胶粘剂粘合在一起，形成“三明治”式结构，其具有强度高、刚度好、重量轻、表面平整度好、隔声隔热的优点，根据光源Honeycomb Panel的特点，采用了常温复合技术，常温复合技术就是将双组分胶粘剂按比例调制好，然后用刮板把调制好的双组分胶粘剂均匀地刮到面、底铝的复合面上，刮好后加入蜂窝芯，按面铝+铝蜂窝芯+底铝的形式放置于模具上，再在上面覆一层膜，膜的四周用胶带进行密封，最后通过抽真空对Honeycomb Panel进行加压，等到6h过后由于胶粘剂的反应固化把面铝+铝蜂窝芯+底铝牢牢地粘合在一起形成Honeycomb Panel。

aluminum honeycomb panelFor the plate with single-track processing method, because the radius of the compound molding of the light source honeycomb plate is different, according to the principle of bow back, a mold with adjustable different radii is developed, which not only ensures the accuracy of the compound plate but also controls the cost of the mold. For the hyperbolic honeycomb plate, the difficulty is the guarantee of the production and accuracy of the mold. The production of hyperbolic mold to process a set of model, the model is the use of the hyperbolic into line and point coordinates of the principle of production, its main function is to test the accuracy of the hyperbolic mold, the accuracy of the model point coordinates should be controlled within +/-1mm. Then, the reference mold is placed on the hyperbolic mold to modulate the hyperbolic mold. The error between the hyperbolic mold and the reference mold is controlled within 3mm. After the modulation is completed, the composite placement position of the hyperbolic honeycomb plate is drawn according to the reference mold, and the composite honeycomb plate can be started. Composite good honeycomb board to achieve good accuracy.
