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，那么对于凹陷的山东铜门该如何还原呢?

Copper doors are a type of product that is widely used by people. They have good performance, strong compression resistance, and beautiful appearance, which are welcomed by the majority of users. Good daily maintenance can extend the use time and make full use of their performance in practical applications. However, if the copper door is damaged, it will affect its use, especially if there is a depression that directly affects the use effect of the copper door. So how to restore the concave Shandong copper door?

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。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 the negative pressure of a vacuum machine to suck up the depression. This method is only suitable for copper doors with thinner sheet metal, but it is not suitable if the sheet metal is thicker. Different types of copper doors have different reduction methods. Use a high-strength magnet to suck it up. Since the middle of the door is empty, you can use a neodymium iron boron strong magnet to place it in the hollow part of the door, and use a weakly magnetic iron wire to guide the outside to allow the strong magnet to reach the concave part. Then, use a high-strength electromagnet to attract the outside. You can lift a copper plate concave 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 a plurality of copper sticks at the concave part of the copper door as the point of application, and use hydraulic pressure or wheel changing group for strong traction to lift the concave part of the copper plate. Use the same grinding wheel to smooth the restored recesses. The positions with arcs or edges 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.

铜门厂家告诉你铜门的保养很重要，保持外面油漆的完整性，防止磕碰和撞击，出现凹陷的问题，用户可以结合文章讲述的方法处理，如果表面的漆脱落需要刷铜门相近的油漆，平常我们可以用干毛巾对它进行清洁。
