Abstract
The invention discloses production technology for a novel corrosion resistance brush. The production technology sequentially comprises steps that: step 1, raw materials are selected and are cobalt powder, graphite powder, resin and a lubrication material respectively; step 2, the cobalt powder, the graphite powder, the resin and the lubrication material are mixed in a weight ratio of 4:3:2:2; step 3, the mixture is disposed in a die and is pressed to form a semi-finished product, and the pressure is 1700-2000MPa; step 4, silver oxide is uniformly sprayed on a surface of the semi-finished product, and thickness of the silver oxide is 0.08-0.1mm; and step 5, deburring is carried out, and finishing and molding are carried out. The production technology has advantages of simple technology, easy operation, relatively good corrosion resistance performance and relatively long service life.
Description
Technical field
The present invention relates to a kind of production technology of brush, relate in particular to a kind of production technology of novel corrosion resistant brush.
Background technology
Brush is to do sliding contact and form a kind of conductive component being electrically connected with movement parts.Brush is for commutator or slip ring, as the sliding contact body that imports and exports electric current.Its conduction, heat conduction and greasy property are good, and have the instinct of certain mechanical strength and commutation property spark.Nearly all direct current machine and commutating machine all use brush, and it is the important composition parts of motor, and brush application is in daily life more and more extensive, and a lot of household electrical appliance all need to use brush, such as dust catcher, and family-use grinder etc.Brush in the course of the work, has chemicals or greasy dirt to enter the pore of surface of the electric brush, and then corrodes brush, causes the waste of brush.
Summary of the invention
Technical problem to be solved by this invention is to provide the production technology of the simple corrosion-resistant brush of a kind of technique.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of production technology of novel corrosion resistant brush, and this production technology comprises successively:
Step 1: choose raw material, be respectively cobalt powder, graphite powder, resin, lubriation material;
Step 2: the ratio that is 4:3:2:2 according to weight ratio by described cobalt powder, graphite powder, resin, lubriation material is mixed;
Step 3: described mixture is placed in mould and is pressed into semi-finished product, and described pressure is 1700MPa-2000MPa;
Step 4: at the spray silver oxide of described half-finished surface uniform, the thickness of described silver oxide is 0.08mm-0.1mm;
Step 5: deburring, finishing moulding.
Described pressure is 1850 MPa.
Described thickness is 0.09mm.
Compared with prior art, beneficial effect of the present invention is:
Because the production technology of brush of the present invention has adopted processing step and the condition of rational structure and science, so can produce the good brush of corrosion resistance, especially sprayed after silver oxide, make corrosion resistance more stable, and production process is few, easy to operate, therefore technique of the present invention is simple, easy to operate, corrosion resistance is better, and useful life is longer.
Embodiment
?describe the present invention in detail below in conjunction with embodiment

Step 3: described mixture is placed in mould and is pressed into semi-finished product, and described pressure is 1700MPa-2000MPa;
Step 4: at the spray silver oxide of described half-finished surface uniform, the thickness of described silver oxide is 0.08mm-0.1mm;
Step 5: deburring, finishing moulding.
Above-mentioned production technology has adopted processing step and the condition of rational structure and science, thus can produce the good brush of corrosion resistance, and production process is few, easy to operate.
embodiment 1
A production technology for novel corrosion resistant brush, this production technology comprises successively:
Step 1: choose raw material, be respectively cobalt powder, graphite powder, resin, lubriation material;
Step 2: the ratio that is 4:3:2:2 according to weight ratio by described cobalt powder, graphite powder, resin, lubriation material is mixed;
Step 3: described mixture is placed in mould and is pressed into semi-finished product, and described pressure is 1850MPa;
Step 4: at the spray silver oxide of described half-finished surface uniform, the thickness of described silver oxide is 0.09mm;
Step 5: deburring, finishing moulding.
In sum, technique of the present invention is simple, easy to operate and corrosion-resistant, the life-span is longer.
The foregoing is only preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned execution mode; in every case the equivalence that those of ordinary skills do according to disclosed content is modified or is changed, and all should include in the protection range of recording in claims.
