Abstract
The invention relates to an automobile starting motor, and provides a novel carbon fiber enhanced copper graphite composite electric brush for an electric generator and a manufacturing method of the novel carbon fiber enhanced copper graphite composite electric brush. Carbon fiber short yarns and carbon nanotubes subjected to surface metal treatment, and modified phenolic resin are subjected to surface gum dipping treatment, then, asphalt gum powder and copper powder are coated, next, blending agents are added, a carbon fiber composite sheet is manufactured, after the belt conducting wire pressing is carried out for four times, the electric brush is manufactured, then, the sintering is carried out, a copper, carbon and carbon fiber interlayer combining body is manufactured, and finally, the chipless machining can be reached through work procedures such as mechanical exquisite processing, planning, R degree processing and chamfering. The novel carbon fiber enhanced copper graphite composite electric brush has the advantages that the connection resistance is small, the operation spark is small, the reversing performance is good, the friction coefficient is low, the operation noise is low, good abrasion resistance is realized, and the service life is long; the capability of forming a motor commutator oxidation film is realized, the commutator surface can be uniform and can be cleaned, and the product is applicable to high and low environment temperature and is suitable to be popularized in a wide range.
Description
Technical field
The present invention relates to a kind of automobile starting motor, generator by brush manufacturing process and
Background technology.
Background technology
Brush is the heart of motor, electric motor of automobile brush requires that commutation ability is good in using in operation, spark is little, coefficient of friction is little, low and the premium properties of noise, the technical requirement that the instructions for use life-span is long, be the difficult point that current industry technology is broken through, domestic market high-end product is monopolized by overseas enterprise always before this always.Domestic urgent need development & production goes out this product and solves domestic demand market.
Summary of the invention
The present invention be solve the brush produced of prior art in use produce spark large, wear no resistance, the problem such as coefficient of friction is large, noise is high when running, a kind of method of manufacturing technology of electric motor of automobile electricity consumption refreshing type is provided.
In order to realize above goal of the invention, the invention provides following technical scheme:
Novel carbon fiber reinforcement copper graphite composite electric brush and manufacture method thereof comprise following content:
The preferred fine carbon fiber filament of the present invention or short silk, after surface metalation process, be cut into the short silk of 0.5-3mm or 6mm.
Carbon fibe, carbon nano-tube and phenol-formaldehyde resin modified surface dipping process.Formula composition: the short silk 3-9% of Carbon fibe, molybdenum bisuphide 3-8%, carbon nano-tube 1-5%, additive 1-5%, modified phenolic 15-20%, phosphatization copper powder 3-6%, surplus are scale graphite fine powder, Carbon fibe and molybdenum bisuphide and additive thereof, carbon nano-tube scale graphite add ethanol in proper amount and make oar material through grinding.Charcoal oar material is parallel to and carries out gluing.Can MULTILAYER COMPOSITE or offset laminar general thickness 0.5mm-3mm by product thickness.
By crystalline flake graphite, fluorographite, Delanium, petroleum coke powder add pitch kneading through high temperature purification treatment and roll sheet and pulverized 100-200 mesh sieve and make pitch rubber powder.Pitch rubber powder mixes with copper powder and additive.
As being applied in reference to customer specifications requirement on automobile starting motor, pressure testing becomes brush length 1/2-1/3 width to be less than brush 1-2mm, and thickness is in the Carbon fibe composite sheet of the 1-3mm of brush thickness.
Layer of charcoal after gluing to carry out 120 ~ 250 DEG C hot-forming, make Carbon fibe composite sheet.
By Carbon fibe composite sheet through shear or punching brush length 1/2, width is less than the flake of brush width 1-2mm.
Carbon fibe composite sheet is placed in brush band line pressure molding jig and by carbon fiber composite block bottom brush.Do not affect wire with upper end to insert.
Gradation in brush mold is scraped into upper and lower two layers of copper powdered carbon material.Middle press-in Carbon fibe composite sheet, and carry out the press-in of band wire, pressure should control at 3-4T/c ㎡.(see figure 1)
To first scrape into copper carbon dust material in brush mold, press-in Carbon fibe composite sheet, then carry out band line pressure system, Stress control be at 3-4T/cm
2, (see figure 2)
First be pressed into Carbon fibe composite sheet by brush mold, scrape into copper carbon dust material, then be pressed into Carbon fibe composite sheet, then carry out the compacting of band wire, Stress control is at 3-4 T/cm
2, (see figure 3)
First be pressed into Carbon fibe composite sheet by brush mold, scrape into copper carbon dust material, then carry out the compacting of band wire, Stress control is at 3-4 T/cm
2, (see figure 4)
Align the brush press-in copper conductor degree of depth after die trial, brush thickness generally will have+0.05 ~ 0.2mm allowance, and conductor length is sheared according to customer requirement.
Brush after compacting naturally is down to normal temperature through 750-850 DEG C of Buchholz protection sintered heat insulating after 2 hours by the heating rate of 1-2 DEG C/min, obtains copper, charcoal, Carbon fibe interlayer combination.
After brush sintering, also will through mechanical retrofit, the operations such as plane, R degree, chamfering, can reach chipless machining.
