Description

Technical Field

[0001] The utility model relates to the technical field of electroplating processing, in particular to an electroplating insulation hanging device. Background Technique

[0002] During the surface treatment electroplating process of steel parts, some products only need partial electroplating. There are many methods for partial electroplating. The most common ones are the encapsulation method and the glue coating method. The encapsulation method is to use insulating materials such as plastic films, tapes, plastic pipes, and rubber stoppers to block and wrap the non-plated parts. Although this method is simple and convenient, it is not easy to insulate parts with complex shapes; the glue coating method is time-consuming, has a long waiting time, low production efficiency, and the insulating glue has volatile irritating odors, which is not conducive to the physical health of employees.

[0003] During the surface treatment process in the workshop, there are weak links in the insulation protection step of parts. For example, Figure 1 In the production of the speed governor hydraulic valve shown, it is required to galvanize the rest of the surface except for the 23.8 mm section (excluding the end face M). The batch quantity of this part is about 200 pieces. The original clamping and insulation protection methods are: using iron wires for clamping and conducting electricity, using iron wires for clamping (the clamping positions are shown in the figure), using 2 mm rubber round pieces to insulate the end face at φ20, and finally using plastic pipes to protect the parts to be insulated. This insulation method is cumbersome to operate. It takes about 3 minutes to clamp one part, and the insulation time for the whole batch of parts is about 10 hours. In addition, after plating, due to the gaps between the parts and the iron wires and insulating materials, there are different degrees of non-plating phenomena in each part, and grinding is required. The grinding time for each part is about 5 minutes, which is time-consuming and laborious. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electroplating insulation hanging device to solve the problems existing in the above-mentioned prior art, which can improve the hanging efficiency, save the insulation protection time, and improve the non-plating phenomenon of parts.

[0005] To achieve the above purpose, the utility model provides the following scheme:

[0006] The utility model provides an electroplating insulation hanging device, which includes a steel tooling plate. Insulation holes capable of inserting a hydraulic valve are formed in the tooling plate. An insulation sealing layer is arranged between the outer wall of the hydraulic valve and the inner wall of the insulation hole, and an interference fit is arranged between the hydraulic valve and the insulation sealing layer.

[0007] Preferably, multiple rows of insulation hole units are uniformly formed in the tooling plate, and a row of relief hole units is arranged between any two adjacent rows of insulation hole units.

[0008] Preferably, five rows of insulating hole units are evenly formed in the tooling plate, and each row of the insulating hole units includes ten insulating holes arranged in sequence.

[0009] Preferably, each row of the relief hole units includes nine relief holes arranged in sequence.

[0010] Preferably, the insulating and sealing layer is made of insulating material.

[0011] The utility model has achieved the following technical effects compared with the prior art:

[0012] In the electroplating insulating hanging device provided by the utility model, an insulating and sealing layer is arranged on the inner wall of the insulating hole. When the hydraulic valve is inserted into the insulating hole, the insulating and sealing layer can wrap the part of the hydraulic valve that does not need electroplating, realizing the insulation of this section. The hanging process is simple and fast, greatly saving the insulation protection time. At the same time, the consumption of hanging wire is saved, and the phenomenon of parts missing plating is improved. BRIEF DESCRIPTION OF THE DRAWINGS
