山东铜门是人们使用比较多的一种门类产品，它的性能好，抗压能力强，外观美观受到广大用户的欢迎，做好日常维护保养可以延长使用时间，让它的性能在实际应用中充分发挥，但是如果铜门受损就会影响使用，尤其是出现凹陷会直接影响铜门的使用效果，那么对于凹陷的铜门该如何还原呢?下面我们山东铜门生产厂家就来带大家了解了解。

Shandong copper doors are a type of product widely used by people. They have good performance, strong pressure resistance, and beautiful appearance, which are welcomed by a large number of users. Proper daily maintenance can prolong their use time and fully utilize their performance in practical applications. However, if the copper door is damaged, it will affect its use, especially if there is a dent, which will directly affect the effectiveness of the copper door. So how to restore the sunken copper door? Next, we, Shandong copper door manufacturers, will take you to learn more.

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。

Using the negative pressure of a vacuum machine to suck up the depression is only suitable for copper doors with thin sheet metal, and it is not suitable if the sheet metal is thick. Different types of copper gates have different restoration methods.

用高强磁铁吸起来，由于铜门中间是空的，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 lift it up. As the middle of the copper door is empty, a neodymium iron boron strong magnet can be placed in the hollow part of the door. Use a wire with weaker magnetism to guide the strong magnet to the concave part, and then use a high-strength electromagnet to attract it externally. This can lift a copper plate with a thickness of about 1mm into the concave part. If the thickness is higher, the third method should be used.

在山东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。

Welding multiple copper branches at the depression of Tongmen, Shandong as the point of force, and using hydraulic or wheel changing sets for traction can lift the copper plate depression. Use the same grinding wheel to smooth out the restored depressions, and any curved or angular positions must be consistent with the overall image of the door. If there are welded copper branches, first polish them off, and then further polish them smooth.
