Embodiment
[0019] Such as figure 1 The spiral electroplating equipment for coiled welded pipe shown in the figure is provided with a drum 1 in the electroplating tank, and the drum 1 is connected to a driving device and rolled by the driving device; the outer diameter of the drum 1 is the same as the outer diameter of the rough rolled welded pipe The ratio is 100:1; the drum is provided with a surrounding track 2, so that the rough rolled welded pipe can be spirally wound on the drum along the surrounding track 2 for electroplating; there are also several power supply points 3 on the drum, between the power supply points 3 The distance between them is 50 times the outer diameter of the rough rolled welded pipe.
[0020] working principle:
[0021] In the present invention, by setting a surrounding track on the drum, before electroplating, the rough rolled welded pipe is helically wound on the drum along the surrounding track, and then put into the electroplating tank for electroplat...

The invention relates to electroplating equipment, in particular to coil-welded tube screw type electroplating equipment. According to the coil-welded tube screw type electroplating equipment, a roller is arranged in an electroplating bath so that blank coil-welded tubes can be wound around the roller spirally to be electroplated. According to the coil-welded tube screw type electroplating equipment, the coil-welded tubes are wound around the roller spirally, so that the purposes that more blank coil-welded tubes can be put into the electroplating bath of the same size and can be electroplated incessantly are achieved. Therefore, the occupied area of the electroplating equipment is reduced while the electroplating efficiency is improved, and the equipment cost is reduced.
Description
technical field [0001] The invention relates to an electroplating equipment, in particular to a coiled pipe spiral electroplating equipment. Background technique [0002] The existing coil welded pipe electroplating technology mainly adopts the linear processing method, and the long-line equipment slowly pulls the plating. This processing method occupies a large area and the electroplating efficiency is low. Since the electroplating time is fixed, at present the main method is to increase the volume of the plating tank to increase the number of blank tubes in the plating tank so as to achieve the purpose of improving the electroplating efficiency. Although this improved method improves the electroplating efficiency, it fails to overcome the defects that the electroplating equipment occupies a large area and the equipment cost is high. At the same time, the electroplating effect is not good due to the different magnitudes of the electric current in the electroplating tank ...
