Processing conditions of honeycomb aluminum plate

1. Deepen the three-dimensional model of the roof (curtain wall) system,Honeycomb aluminum plateThe deepening process is to analyze and simulate each plate through a special computer design software to determine the processing 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 in different positions on the single mold to form the position difference of four corner points.

Honeycomb aluminum plateThen 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. If it is greater than ± 3mm, it is necessary to process 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.根据开料加工图对铝板进行数控切割，使用数控转塔冲切，保证板块的加工尺寸精度在±2mm之内，Honeycomb aluminum plateAfter cutting is completed, if it is a hyperbolic plate, it needs to be rolled to eliminate the internal stress of the aluminum plate and prevent the rebound deformation of the composite forming hyperbolic honeycomb plate in the following sequence. After cutting is completed, it is hemming processing. 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.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。对于采用单曲加工方式的板块来说，由于光源Honeycomb Panel复合成型的半径是各不相同的，根据弓背原理，开发出了可调节不同半径的模具，这样既保证了复合成板的精度又很好地控制了模具成本，对于双曲的Honeycomb Panel来说难度就是模具的制作及精度的保证。双曲模具的制作先要加工一套靠模。

The model is made by the principle of turning hyperbolic into line and point coordinates. Its main function is to test the accuracy of hyperbolic mold. The accuracy of point coordinates of the model 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.

However, the processing of honeycomb aluminum plates shall meet the following requirements:

1. The size and shape of the incision shall be determined according to the assembly requirements, and the inner surface of the outer aluminum plate of the honeycomb aluminum plate shall not be scratched when the aluminum core is removed. 0.3~0.5mm aluminum core should be retained on the outer aluminum plate of each part;

2. For the processing of right-angle components, the corners should be bent into circular arcs, and the corner seams should be sealed with silicone weather-resistant sealant;

3, the processing of large arc angle components, arc parts should be filled with fireproof materials;

4. For the processing of the edge, the outer aluminum plate should be folded 180 °, and the aluminum core should be encapsulated.
