Embodiment 1

[0027] The present embodiment proposes a kind of brush production line, comprises the following steps:

[0028] S1: Graphite raw material, put the graphite raw material into the stirring tank, the graphite raw material is powdery, its particle size is 46mm, add hydrofluoric acid into the stirring tank, use the stirring rod to stir the stirring tank every 2min , the number of stirring times is 4 times, the graphite blank and hydrofluoric acid are fully mixed and reacted to obtain a mixture, the mixture is put into a filter bag, and it is washed with clean water every 3 minutes, and the number of times of washing is 5 times. The mixture is dehydrated to obtain a filter cake, and the reactor is preheated, and the filter cake is put into the reactor, and the temperature of the reactor is raised to 200°C, and the filter cake is heated for 20 minutes to dry the filter cake to obtain purified graphite. It is crushed to 16mm by a crusher, and then the crushed purified graphite is grou...

Embodiment 2

[0038] The present embodiment proposes a kind of brush production line, comprises the following steps:

[0039] S1: Graphite raw material, put the graphite raw material into the stirring tank, the graphite raw material is powdery, its particle size is 48mm, add hydrofluoric acid into the stirring tank, use the stirring rod to stir the stirring tank every 4min , the number of times of stirring is 6 times, so that the graphite blank and hydrofluoric acid are fully mixed and reacted to obtain a mixture, the mixture is put into a filter bag, and it is washed with clean water every 5 minutes. The number of times of washing is 7 times. After washing, the Dehydrate the mixture to obtain a filter cake, preheat the reactor, put the filter cake into the reactor, raise the temperature of the reactor to 220°C, heat the filter cake for 30 minutes, and dry the filter cake to obtain purified graphite. It is crushed to 18mm by a crusher, and then the crushed purified graphite is ground by a p...

Embodiment 3

[0049] The present embodiment proposes a kind of brush production line, comprises the following steps:

[0050] S1: Graphite raw material, put the graphite raw material into the stirring tank, the graphite raw material is powdery, its particle size is 49mm, add hydrofluoric acid into the stirring tank, use the stirring rod to stir the stirring tank every 5min , the number of times of stirring is 7 times, so that the graphite blank and hydrofluoric acid are fully mixed and reacted to obtain a mixture, the mixture is put into a filter bag, and it is washed with clean water every 6 minutes. The number of times of washing is 8 times. After washing, the The mixture is dehydrated to obtain a filter cake, and the reactor is preheated, the filter cake is put into the reactor, the temperature of the reactor is raised to 230°C, and the filter cake is heated for 35 minutes to dry the filter cake to obtain purified graphite. It is crushed to 19mm by a crusher, and then the crushed purifie...

Abstract

The invention discloses a production line for electric brushes, which comprises the following steps: S1: graphite blanks, putting the graphite blanks into a stirring tank, adding hydrofluoric acid into the stirring tank, using a stirring rod to stir the stirring tank every 2-6min Stirring work, the number of stirring times is 4-8 times, so that the graphite blank and hydrofluoric acid are fully mixed and reacted to obtain a mixture, the mixture is put into the filter bag, and it is washed with clean water every 3-7min, the number of times of washing 5-9 times, after washing, the mixture is dehydrated to obtain a filter cake. The invention has a reasonable design, not only can purify and grind the graphite blank, so that the particle size of the graphite blank can be uniform, and then the product can be smoothed, but also can be fully impregnated and solidified, so that the low-molecular polymer can be fully and uniformly diffused into the graphite powder In the gap, milling, reaming, and assembly of graphite raw materials can produce finished brushes, and the finished brushes can be inspected and packaged to ensure product quality.

Description

technical field [0001] The invention relates to the technical field of electric brushes, in particular to a production line of electric brushes. Background technique [0002] The brush is an important component of the motor. It is responsible for conducting current between the rotating part and the stationary part. Because it is mostly made of graphite, it is also called a carbon brush. The brush is mostly assembled on the commutator or slip ring. It is a The sliding contact body needs to have the characteristics of smoothness, wear resistance and good electrical conductivity. [0003] At present, the production process of electric brushes is not perfect. With the continuous expansion of market demand for electric brushes, the supply of electric brushes is in short supply. Therefore, we have designed a production line for electric brushes to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the p...
