用真空机的负压将凹陷吸起来，这种方法只适合钣金较薄的铜门，如果钣金较厚就不适合了。不同类型的铜门还原方法不同。

Use the negative pressure of the vacuum machine to suck up the depression. This method is only suitable for copper doors with thinner sheet metal. If the sheet metal is thicker, it is not suitable. Different types of copper doors have different restoration methods.

用高强磁铁吸起来，由于同门中间是空的，可以用钕铁硼强磁铁放入门的中空部位，外部用磁性较弱的铁丝引导，让强磁铁到达凹陷部位，然后外部用高强度电磁铁吸引，可以把厚度1mm左右的铜板凹陷提起来，如果厚度更高，就要用第三种方法。

Use a high-strength magnet to suck it up. Since the middle of the same door is empty, you can use a NdFeB strong magnet to put it in the hollow part of the door. Use a weak magnetic wire to guide the outside so that the strong magnet can reach the hollow part. Then use a high-strength electromagnet to attract the outside. You can lift the copper plate with a thickness of about 1mm. If the thickness is higher, you need to use the third method.

在铜门凹陷处焊接多个铜枝作为着力点，用液压或者换轮组进行强力牵引，可将铜板凹陷提起来。同砂轮将还原的凹陷打磨平整，有弧线或者棱角的位置一定要和门的整体形象统一，如果有焊接铜枝，先把铜枝打磨掉，然后再进一步打磨平整。

Weld several copper branches at the copper door recess as the force point, and use hydraulic pressure or wheel change set for strong traction to lift the copper plate recess. The restored depression shall be polished with the same grinding wheel, and the position with arc or corner must be consistent with the overall image of the door. If there are welded copper sticks, they shall be polished off first, and then further polished.
