Solution for concave treatment of copper profiles for rotary doors

1、用真空机负压吸凹陷，这种方法只适用于金属薄板的旋转铜门型材，如果金属薄板较厚，则不适合。

1. Using a vacuum machine to suction the depression under negative pressure is only suitable for rotating copper door profiles of metal sheets. If the metal sheet is thick, it is not suitable.

2,高强度磁铁,由于门中间是空的,可以使用钕铁硼强磁铁把空心部分的介绍,外部使用弱磁线指导,使凹陷强大的磁铁,和外部使用高强度磁铁吸引,能举起厚度约1毫米铜凹陷,如果厚度较高,第三种方法。

2. High strength magnet. As the middle of the door is empty, a neodymium iron boron strong magnet can be used to introduce the hollow part. The outer part is guided by a weak magnetic wire to make the concave strong magnet, and the outer part is attracted by a high strength magnet, which can lift a copper concave with a thickness of about 1mm. If the thickness is higher, the third method is used.

3、在旋转铜门型材凹陷处焊接铜分支为着力点，用液压或轮组作强力牵引，可抬起铜板凹陷处。

3. Weld copper branches at the concave part of the rotating copper door profile as the focus, and use hydraulic or wheel assembly for strong traction to lift the concave part of the copper plate.
