Description

Technical Field

[0001] The utility model relates to the technical field of chemical plating, in particular to a rotary composite plating device. Background Art

[0002] Chemical plating is the most common surface treatment method in industrial production.

[0003] In the current industrial production of chemical plating process, adding hard particles (such as diamond, titanium dioxide, silicon carbide, etc.) can effectively improve the hardness, wear resistance and corrosion resistance of the coating, forming chemical composite plating, the hard particles are in a suspended state, accompanied by chemical deposition on the surface of the workpiece, some of the suspended hard particles settle downward under the action of their own gravity, and the particles that land on the surface of the workpiece will adhere to the surface of the workpiece with the chemical deposition. As the chemical deposition layer thickens, these deposited particles will be gradually wrapped in the chemical deposition layer to form a composite coating. That is, the chemical composite plating process can effectively improve the hardness, wear resistance and corrosion resistance of the coating. However, after adding hard particles for a period of time, a violent spontaneous reaction will occur, the plating solution will become invalid and cannot be used normally (the plating solution at this time can only be discarded, causing waste), and a coating cannot be formed on the surface of the workpiece; especially when adding micron-sized hard particles, there is a large specific surface area. This feature makes the hard particles have a large surface activity in the chemical plating solution, which is not only easy to cause the plating solution to deposit on the particle surface, but also difficult to control. Once the self-reaction is induced, the effective ingredients in the plating solution will be quickly consumed. Therefore, the plating solution after adding hard particles has a certain period of validity. According to the characteristics of different plating solutions, the validity period is within a dozen minutes to several hours. After the validity period, the plating solution will completely lose its activity. In order to avoid the failure of the composite plating solution and make the composite plating solution have a longer validity period, a common practice is to set a stirring device and a heating device in the liquid storage tank, the stirring device stirs the plating solution, the blades of the stirring device rotate to make the solution flow, maintain the hard particles in a suspended state, and heat the plating solution through the heating device.

[0004] In actual production, all surfaces of the workpiece are usually required to be covered with a uniform composite coating (especially for small workpieces). However, the particles in the composite plating solution can only settle on the upward surface or the approximately upward surface of the workpiece under the action of their own gravity. The workpiece is fixed in the plating tank, and the side and bottom surfaces of the workpiece cannot obtain particles. It is impossible to form a composite coating on all surfaces of the workpiece.
