specific Embodiment approach 1
[0018] Specific implementation mode 1: The bearing cage finishing cleaning method of this embodiment, the steps of the bearing cage finishing cleaning method are as follows:
[0019] Step 1. Using oblique triangular brown corundum with a particle size of 90-100 as the light decoration material;
[0020] Step 2. According to the pocket size of the bearing cage, select the corresponding specification of the finishing material:
[0021] When the pocket size of the bearing cage is 5-10mm, the specification of the selected glossy material is 12X15mm;
[0022] When the size of the pocket of the bearing cage is 10-18mm, the specification of the selected glossy material is 20X23mm;
[0023] When the size of the pocket of the bearing cage is 18-30mm, the specification of the selected glossy material is 33X35mm;
[0024] Step 3. Use the existing finishing machine, the weight of the finishing material is 175kg, and the amount of finishing fluid is 800-1000ml of anti-rust solution;

specific Embodiment approach 2
[0027] Specific implementation mode 2: After the finishing in step 4 of this implementation mode, place the bearing cage in the anti-rust tank, remove it after 1 minute, and tilt the bearing cage to stand for 0.5-1 minute. In this way, the surface quality of the bearing cage after silver plating is improved. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0028] Embodiment 3: The finishing liquid in step 3 of this embodiment is a mixture of sodium nitrite and water, and the weight ratio of sodium nitrite to water is 1:2. In this way, the anti-rust effect is good. Other steps are the same as those in Embodiment 1 or 2.

Abstract
The invention discloses a method for finishing and cleaning a bearing cage, which relates to a method for cleaning and finishing a cage. The invention solves the problem that different degrees of thorn-like bumps appear on the surface of the outer diameter or inner diameter of the existing bearing cage after silver plating, the silver plating quality of the bearing cage cannot meet the technical requirements of the product, and the problem of increasing the manufacturing cost of the bearing exists. Step 1. Use oblique triangular brown corundum with a particle size of 90-100 as the finishing material; Step 2. Select the corresponding specifications of the finishing material according to the pocket size of the bearing cage; Step 3. Use the existing finishing machine. The weight of the finishing material is 175kg, and the amount of finishing liquid is 800-1000ml of anti-rust liquid; step 4, determine the number of bearing cages in the finishing machine according to the outer diameter specification of the bearing cage, and use the finishing machine to fix the bearing cage Carry out polishing and cleaning, and the polishing time is 2.5 to 3.5 hours. The invention is used for cleaning the surface of the bearing cage.
Description
technical field [0001] The invention relates to a method for cleaning the light decoration of a bearing cage, in particular to a method for improving the cleanliness of the cage before silver plating, so as to ensure that the silver plating quality of the cage meets product technical requirements. Background technique [0002] During the silver plating period of the bearing cage from December 2014 to June 2015, various types of bearing cages made of 40CrNiMoA had different degrees of thorny bumps on the surface of the outer diameter or inner diameter after silver plating, and the bearing cage can only be desilvered. The method of re-silvering again overcomes the thorn-like bump defect on the surface of the cage and ensures that the silver-plating quality meets product requirements. [0003] A process study was carried out to address this issue. According to the analysis, the thorn-like bumps on the surface of the steel cage after silver plating are related to the cleanlines...
