铜门凹陷如何修复?先要看凹陷面积是否大，因为在所有铜门的日常保养中，凹陷现象是很麻烦的，但是对于 山东铜门厂家来说，这些都不是问题。小编今天就把如何修复铜门凹陷的方法步骤分享给各位读者。

How to repair Tongmen depression? The first thing to see is whether the area of the depression is large, because in the daily maintenance of all copper doors, the depression is very troublesome, but for Shandong copper door manufacturers, these are not problems. Today, the editor will share the methods and steps of how to repair Tongmen depression with readers.

修复凹痕，这也是很难的。有三种方法:

It is also difficult to repair dents. There are three methods:

1.用真空机吸真空。此方法仅适用于薄板铜门。如果板材较厚，则不适用。

1. Vacuum with vacuum machine. This method is only applicable to sheet copper doors. Not applicable if the plate is thick.

2.用高强度磁铁固定。因为同一扇门中间是空的，可以用强力的钕铁硼磁铁将其放置在门的中空部分。在外部，弱磁丝将强磁体引导到凹部，然后被高强度电磁铁向外吸引。可提起约1毫米厚的铜洼地。如果厚度较大，则需要第三种方法。

2. Fix with high-strength magnet. Because the middle of the same door is empty, it can be placed in the hollow part of the door with a strong NdFeB magnet. On the outside, the weak magnetic wire guides the strong magnet to the concave, and then is attracted outward by the high strength electromagnet. A copper depression about 1mm thick can be lifted. If the thickness is large, a third method is required.

3.在铜门凹陷处焊接多根铜支管作为应力点。采用液压牵引或强轮对牵引可消除铜板凹陷。

3. Weld several copper branch pipes at the depression of the copper door as stress points. The copper plate depression can be eliminated by hydraulic traction or strong wheelset traction.

第二步是使用相同的砂轮打磨修复后的凹痕。圆弧或圆角的位置必须与门的整体形象相匹配。如有焊接铜支管，应先打磨铜支管，再打磨。

The second step is to use the same grinding wheel to polish the repaired dents. The position of the arc or fillet must match the overall image of the door. If there is a welded copper branch pipe, the copper branch pipe shall be polished first and then polished.

第三步是用有颜色的腐蚀液对铜门上色，保证整个铜门颜色均匀。

The third step is to color the copper door with colored corrosion liquid to ensure the uniform color of the whole copper door.

第四步是绘画。喷漆防护漆应与铜门防护漆名称或颜色相同。至此，整个铜门凹陷的修复工作已经完成。

The fourth step is painting. The protective paint for painting shall be the same name or color as the protective paint for copper door. So far, the repair of the entire Tongmen depression has been completed.
