Technical Field

The invention belongs to the technical field of electroplating processing, and particularly relates to a sleeve electroplating protection tool for internal sealing protection during sleeve electroplating.

Background

The structure of a door shaft sleeve used by a certain type of product is shown in figure 1, the sleeve is of a through hole structure, the calibers of the upper end and the lower end are different, and the sleeve is not threaded. The inner diameter of the sleeve has the size precision of 0.005, and the outer surface of the sleeve is required to be galvanized. Because the inner diameter precision is too high, the inner surface of the sleeve needs to be strictly protected in the electroplating process, and the corrosion of the inner surface caused by the procedures of pickling and the like in the electroplating process is avoided.

The local electroplating protection is usually performed by methods such as a silica gel protection plug, a protection adhesive tape, a protection film, a metal structural protection tool and the like. The silica gel protective plug is suitable for rack plating, but is easy to fall off and lose efficacy in barrel plating; the protective tape and the protective film are suitable for protecting the outer surface, but not suitable for protecting the inner surface of the sleeve; the metal structure nature protection frock is electrically conductive, leads to the inside electroplating of sleeve easily, and the metal is heavier, can lead to every groove to electroplate quantity and reduce, influences output.

Since the inner surface of the sleeve cannot be plated and cannot be corroded during the plating process, the inner surface is prevented from entering the solution, and therefore, both ends need to be blocked. The conventional protection usually adopts a metal thread plug, but because the inner surface of the sleeve has high finish and two ends have no threads, the sleeve cannot adopt metal to directly protect in order to avoid quality defects caused by collision between metal and metal. Because this sleeve is heavier, should reduce the weight of protection frock as far as possible, avoid leading to the output to descend because of electroplating the limit for weight. In addition, due to production requirements, the electroplating of the sleeve product can adopt rack plating and barrel plating, so that the protection is tightly connected and cannot be loosened in the rolling process.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.

The embodiment provides a sleeve electroplating protection tool, the structure of which is shown in fig. 2. The sleeve electroplating protection tool is made of a nylon 66 material, and the weight of the sleeve electroplating protection tool is 1/7 of that of an iron tool. The nylon 66 has a breaking elongation of 80% and good elasticity, can reduce impact with the sleeve when in use, and is tightly combined with the sleeve to realize a sealing effect.

The electroplating protection tool comprises a phi 12mm rod part and two protection plugs. One of the protective plugs is positioned at the lower end of the rod part and is integrated with the rod part into a whole, and the other protective plug is connected with the rod part through M12 threads at the upper end of the rod part. Through M12 threaded fastening's mode, can make the effective bearing of pole portion to can be at the effective afterburning of the stifled position installation of protection, make the stifled and sleeve contact surface close coupling of protection, thereby realize sealedly. In addition, the contact surface of each protective plug and the sleeve is designed to be 60-75 degrees conical, so that internal interference can be effectively avoided, sufficient deformation space is ensured during thread fastening pressurization, and the quick disassembly is convenient. In addition, two ends of the rod part are additionally provided with phi 10mm hanging holes, so that the sleeve is convenient to hang and stabilize during hanging and plating, and collision of products is avoided.

When the tool is used, the tool with the bottom protection plug penetrates through the inner hole of the sleeve, and the protection plug at the upper end is screwed, so that the two protection plugs are tightly combined with the contact surface of the sleeve, and sealing is realized.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
