Description

Technical Field

[0001] The invention relates to the field of steel strip electroplating, and in particular to a conductive roller and a processing method of the conductive roller. Background Art

[0002] During the electroplating process of steel strips, conductive rollers are needed. At present, conductive rollers are electroplated with a layer of copper over 5 mm thick on the outer surface of the roller and the shaft heads on both sides, and then plated with a layer of chromium to strengthen the surface after machining and rounding. This has the following disadvantages: copper electroplating is time-consuming, has a long processing cycle and high cost; the electroplated chromium layer is thin and has a short service life. Summary of the invention

[0003] The purpose of the present invention is to provide a conductive roller and a processing method of the conductive roller, simplify the processing technology, shorten the processing cycle, reduce the processing cost, improve the strength, increase the wear resistance, and extend the service life of the conductive roller.

[0004] In order to solve the above technical problems, an embodiment of the present invention provides a conductive roller, comprising:

[0005] A roller body and a shaft head body arranged at both ends of the roller body;

[0006] A copper roller sleeve is sleeved outside the roller body, and the copper roller sleeve and the roller body are interference fit;

[0007] A copper shaft head sleeve is sleeved outside the shaft head body, and the copper shaft head sleeve and the shaft head body are interference fit;

[0008] A stainless steel roller sleeve is sleeved outside the copper roller sleeve, and the stainless steel roller sleeve and the copper roller sleeve are interference fit;

[0009] A stainless steel shaft head sleeve is sleeved outside the copper shaft head sleeve, and the stainless steel shaft head sleeve and the copper shaft head sleeve are interference fit;

[0010] After the stainless steel roller sleeve and the stainless steel shaft head sleeve are installed, the outer surface is chrome-plated as a whole.

[0011] In addition, an embodiment of the present invention further provides a method for processing a conductive roller, comprising the following steps:

[0012] S1: Process the roller body and the shaft head body, weld the roller body and the shaft head body, and machine them to the preset size;

[0013] S2: Processing copper roller sleeves and copper shaft sleeves;

[0020] S9: Machined stainless steel roller sleeves and stainless steel shaft sleeves;

However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection in the claims of the present application can be implemented.

Similarly, the copper axis head sleeve 4 is sleeved on the outside of the corresponding axis head body 2, and the copper axis head sleeve 4 and the axis head body 2 have an interference fit; the stainless steel roller sleeve 5 is sleeved on the outside of the copper roller sleeve 3, and the stainless steel roller sleeve 5 and the copper roller sleeve 3 have an interference fit.

[0031] It is not difficult to find from the above content that the use of copper roller sleeve 3 and copper shaft head sleeve 4 instead of electroplated copper simplifies the processing technology, shortens the processing cycle, and effectively reduces the processing cost; in addition, a layer of stainless steel roller sleeve 5 and stainless steel shaft head sleeve 6 are also sleeved outside the copper roller sleeve 3 and the copper shaft head sleeve 4, and after the stainless steel roller sleeve 5 and the stainless steel shaft head sleeve 6 are sleeved, the outer surface of the conductive roller is chrome-plated as a whole, thereby improving the strength, increasing the wear resistance, and extending the service life of the conductive roller.

[0032] Specifically, in the present embodiment, the roller body 1 and the shaft head body 2 are made of carbon steel, and are machined to a preset size after being welded and fixed. The copper roller sleeve 3 is heated and expanded to a suitable size and then sleeved on the outside of the roller body 1. The copper shaft head sleeve 4 is heated and expanded to a suitable size and then sleeved on the outside of the shaft head body 2.

Finally, a layer of chromium is electroplated on the outer surface to increase wear resistance. In actual use, the roller body 1 and the shaft head body 2, the copper roller sleeve 3 and the copper shaft head sleeve 4, and the stainless steel roller sleeve 5 and the stainless steel shaft head sleeve 6 can also be connected and fixed in other ways.
