Description

Technical Field

[0001] The invention relates to the technical field of electroplating, in particular to a horizontal environmentally friendly chrome plating machine. Background Art

[0002] Usually, a metal coating needs to be attached to the surface of metal workpieces or other materials through electroplating to prevent corrosion and extend the service life of the workpiece. Chromium is a silvery-white metal with a slight bluish tint. The chrome coating has a high hardness and excellent heat resistance and friction properties.

[0003] At present, the traditional way of "hard chrome electroplating" of workpieces (plated parts) is to dig a hole underground, build an electroplating tank underground, and suspend the plated parts in the electroplating tank below the ground level for electroplating. However, this "underground electroplating" method is prone to leakage of electroplating liquid and causes underground pollution, making it difficult to meet the environmental protection requirements of "visible, controllable, and recyclable". Because it is an underground equipment, there are many hidden dangers, so "underground electroplating" is no longer suitable for the requirements of the "environmental protection" era.

[0004] However, the existing electroplating machines have fixed anodes, difficult to control electroplating time, serious power consumption, uneven electroplating layer thickness, small power receiving area and other problems. They are also unable to adapt to plated parts of different lengths and sizes.
