Abstract
The invention discloses a production process of a wear-resistant electric brush. The production process sequentially comprises the following steps of: selecting raw materials which are coke powder, copper powder, silver powder, copper sulphide and a binding agent; 2, mixing the coke powder, the copper powder, the silver powder, the copper sulphide and the binding agent according to a weight ratio of 6: 2: 1: 1: 2; 3, putting the mixture in a stirrer and crushing to form powder; 4, putting the powdered mixture into a mold and extruding to prepare a semi-finished product, wherein the pressure is 200-260MPa; 5, washing the semi-finished product and airing; 6, putting the aired semi-finished product into a mold and carrying out finished forming; and 7, detecting to select qualified products. Therefore, the production process disclosed by the invention has the advantages of simple process, lower noise and better wear resistance.
Description
Technical field
The present invention relates to a kind of production technology, relate in particular to a kind of production technology of non-dusting brush.
Background technology
Brush is to do sliding contact and form a kind of conductive component that is 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 in daily life is 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.But general common brush has short, not wear-resisting, the shortcoming such as spark is large in useful life.
Summary of the invention
Technical problem to be solved by this invention provides the production technology of the novel brush that a kind of technique is simple, noise is less, resistance to wear is good.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of production technology of non-dusting brush, and this production technology comprises successively:
Step 1: choose raw material, be respectively coke blacking, copper powder, silver powder, curing copper, binding agent;
Step 2: be the ratio mix and blend of 6:2:1:1:2 according to weight ratio with coke blacking, copper powder, silver powder, curing copper, binding agent;
Step 3: with above-mentioned compound be placed on be ground in the mixer Powdered;
Step 4: described pulverous mixture is placed in the mould pushes, make semi-finished product, described pressure is 200MPa-260MPa;
Step 5: described semi-finished product are cleaned, dry;
Step 6: the semi-finished product after will drying are placed on finishing moulding in the mould;
Step 7: detect, choose qualified product.
Described pressure is 230MPa.
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 it is less to produce noise, resistance to wear is brush preferably, and production process is few, easy to operate, so technique of the present invention is simple, noise is less, resistance to wear is better.
Embodiment

Step 7: detect, choose qualified product.
Above-mentioned production technology has adopted processing step and the condition of rational structure and science, so it is less to produce noise, resistance to wear is brush preferably, and production process is few, easy to operate.
Embodiment 1:
A kind of production technology of novel brush, this production technology comprises successively:
Step 1: choose raw material, be respectively coke blacking, copper powder, silver powder, curing copper, binding agent;
Step 2: be the ratio mix and blend of 6:2:1:1:2 according to weight ratio with coke blacking, copper powder, silver powder, curing copper, binding agent;
Step 3: with above-mentioned compound be placed on be ground in the mixer Powdered;
Step 4: described pulverous mixture is placed in the mould pushes, make semi-finished product, described pressure is 230MPa;
Step 5: described semi-finished product are cleaned, dry;
Step 6: the semi-finished product after will drying are placed on finishing moulding in the mould;
Step 7: detect, choose qualified product.
In sum, technique of the present invention is simple, easy to operate.
The above only is preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection range of putting down in writing in claims.
