Once the copper door is sunken, it will seriously affect the beautiful effect of the copper door, so how should we solve it? Next for you Let's introduce it in detail.

你可以用真空机的负压来吸收压力。这种方法只适用于薄金属板的铜门，但如果金属板厚则不适用。不同种类铜门的还原方法不同。

You can use vacuum to absorb pressure. This method is only applicable to copper doors with thin metal plate, but not if the metal plate is thick. Different types of copper doors have different reduction methods.

如果用高强磁铁吸上去，铜门的中间空着，用钕铁硼强磁铁放入入门的中空部，外部用磁性弱的铁丝引导，强磁铁到达凹陷部，外部用高强电磁铁吸引，能够提起厚度1mm左右的铜板的凹陷，厚度更厚的话，需要第三种方法。

If a high-strength magnet is used to suck it up and the middle of the copper door is empty, a Nd-Fe-B strong magnet is put into the hollow part of the door. The outside is guided by a weak magnetic iron wire, and the strong magnet reaches the concave part. The external high-strength electromagnet can lift the depression of the copper plate with a thickness of about 1 mm. If the thickness is thicker, a third method is needed.

山东铜门凹陷处焊接多根铜枝作为着力点，通过液压或轮组强力牵引，可提升铜板凹陷。用砂轮，将还原的凹陷打磨平整。弧形或边缘的位置需要与门的整体图像一致。如果有焊接的铜枝，先打磨掉铜枝，然后再进一步打磨平整。

Many copper branches are welded at Tongmen depression in Shandong Province as the point of force. The copper plate depression can be lifted by hydraulic or wheel group strong traction. Use grinding wheel to smooth down the restored depression. The position of the arc or edge needs to be consistent with the overall image of the door. If there is welding copper branch, first grind off the copper branch, and then further polish flat.
