The daily damage of copper door is better to repair. Generally, grinding, polishing, plastic, painting and other methods can be used to recover. But once there is a concave phenomenon, the repair of copper doors is the most difficult work, so how to repair the concave copper doors?

　　一步是修复凹陷，这也是更困难的一步。有三种方法:

　　One step is to repair the depression, which is also the most difficult step. There are three ways:

　　真空机带负压会下垂，这种方法只适用于铜门较薄的金属板材，如果金属板材较厚则不适用。

　　Vacuum machine with negative pressure will sag, this method is only applicable to the thin metal plate of copper door, if the metal plate is thick, it is not applicable.

　　2,高强度磁铁,因为中间的东西是空的,可以使用钕铁硼强磁铁把空心部分的介绍,外部使用弱磁线指导,使凹陷强大的磁铁,和外部使用高强度磁铁吸引,能举起厚度约1毫米铜凹陷,如果厚度较高,第三种方法。

　　2. The high-strength magnet, because the middle part is empty, can use the NdFeB strong magnet to introduce the hollow part, use the weak magnetic wire outside to guide, make the strong magnet of the hollow, and use the high-strength magnet outside to attract, can lift the copper hollow with a thickness of about 1mm, if the thickness is high, the third method.

　　3、在铜门凹陷处焊接若干铜支路为受力点，用液压或车轮组作强牵引，可将铜板凹陷提起。

　　3. A number of copper branches are welded in the copper door depression as the stress points, and the copper plate depression can be lifted by using hydraulic pressure or wheel group as strong traction.

　　第二步是用砂轮将修复后的凹陷磨平。弧形或边角的位置必须与门的整体形象一致。如果有焊接好的铜树枝，先打磨掉铜树枝，然后再进一步打磨。

　　The second step is to use the grinding wheel to smooth the repaired depression. The position of the arc or corner must be consistent with the overall image of the door. If there are welded copper branches, first polish the copper branches, and then further polish them.

　　第三步，上色，用上色时腐蚀铜门的颜色，以保证整个铜门的颜色均匀。

　　The third step is to apply color. When applying color, the color of the copper door will be corroded to ensure the color of the whole copper door is uniform.

　　第四步，是喷漆，用相同的名称或颜色的铜门保护漆进行漆面保护，以此，整个铜门凹陷的修复完成。

　　The fourth step is to paint, protect the paint surface with the same name or color of copper door protective paint, so as to complete the repair of the entire copper door depression.
