Abstract
The utility model discloses an automobile synchronizer cone ring composed of copper and iron metal which is manufactured by the pressure sintering method. The automobile synchronizer cone ring composed of copper and iron metal is accompanied with the properties of copper-base alloy and iron-base alloy.
Description
The present invention relates to a kind of bimetallic sintered metal product, specifically, is a kind of copper, iron double metal automobile synchronizer conical ring with the pressure sintering manufactured.It is one of important components in the automobile gearbox.
The automobile synchronizer conical ring requires to have certain intensity, hardness and good wearability.As everyone knows, the corrosion resistance and the toughness of generally casting acid bronze alloy or its agglomerated material are good, but its intensity is low.Ferrous alloy or its agglomerated material have high density and intensity, but its wearability and corrosion resistance are not as good as acid bronze alloy or its agglomerated material.
Main purpose of the present invention provides copper, the iron double metal goods of a kind of intensity height, wearability and excellent corrosion resistance.This goods have acid bronze alloy and two kinds of properties of materials of ferrous alloy concurrently.
Goods of the present invention are compared with casting acid bronze alloy or its agglomerated material, can obtain higher intensity, hardness and more satisfied anti-wear performance, thereby improve the service life of automobile synchronizer conical ring.Because iron has replaced the most copper in the acid bronze alloy, therefore reduced the manufacturing cost of automobile synchronizer conical ring simultaneously.
Automobile synchronizer conical ring of the present invention partly is made up of acid bronze alloy part and ferrous alloy, its concrete structure, shape and neglect requirement greatly and decide.The manufacturing process of these goods is simple.Generally copper alloy that will prepare in advance (Cu-Al-Ni-Fe) and ferroalloy (Fe-Cu-C) powder are done in blender respectively and were mixed 12～24 hours.Pack into after do mixing in the mould, with 3～6 tons/centimetre
2Pressure carry out cold moudling, and then, the mould that blank is housed is put in the pressure sintering device, in 800～950 ℃, 50～250 kilograms per centimeter (for example high strength graphite and industrial ceramics etc.) in the mould that it is special that the blank of cold moudling is packed into
2Carry out pressure sintering under the sintering condition of pressure and 0.3～3 hour.Carry out suitable heat treatment behind the sintering again.
Embodiment one
The manufacturing of a kind of bimetallic automobile synchronizer conical ring of embodiments of the invention one expression.Its concrete manufacturing step is as follows:
With Cu-10Al-4Ni-1Fe and Fe-5Cu-0.7C(numeral percetage by weight) powder of two kinds of different-alloys is respectively charged into to do in two V-type blenders and mixed 16 hours.Then the powder that mixes is packed in the steel die by a powder filling device, (pressure is 6 tons/centimetre to carry out cold moudling on 300 tons of hydraulic presses
2), be that ferrous alloy and outer ring are the bimetallic ring-type goods of acid bronze alloy and obtain inner ring.In the graphite jig that it is special that this powder compact is packed into, and be placed on again in the sintering equipment of pressurization.In 850 ± 5 ℃ temperature and 130 kilograms per centimeter
2Pressure under sintering 1 hour, shed pressure then, be warming up to 950 ± 5 ℃ of knots 1 hour of reburning, with the stove cool to room temperature.Be heated to 950 ℃ then, be incubated shrend after 20 minutes.350 ℃ of following tempering 1 hour, promptly get the copper, the iron double metal automobile synchronizer conical ring that meet performance requirement.
Embodiments of the invention two and embodiment three are the manufacturing of a kind of copper, iron double metal automobile synchronizer conical ring equally.
Embodiment two
Method batch mixing, compacting and shove charge that the powder of Cu-8Al-3.5Ni-1.5Fe and two kinds of prescriptions of Fe-4Cu-0.75C is pressed embodiment one.890 ± 5 ℃ and 100 kilograms per centimeter
2Pressure under sintering 2 hours, with the stove cool to room temperature.Be heated to 980 ℃ then, protect shrend after 1 hour.250 ℃ of tempering 0.5 hour, also obtain meeting the product of performance requirement.
Embodiment three
The metal dust of Cu-8.5Al-3Ni-2Fe and two kinds of prescriptions of Fe-6Cu-0.7C is carried out batch mixing, compacting and shove charge by the method for embodiment one.In 950 ± 5 ℃ temperature and 50 kilograms per centimeter
2Pressure under sintering 0.5 hour, release is with the stove cool to room temperature.Heat-treat by the method for embodiment one then.Also can obtain meeting the product of performance requirement.
The performance of prepared automobile synchronizer conical ring is after tested as following table 1:
The mechanical performance of table 1 automobile synchronizer conical ring
| The automobile synchronizer conical ring | φ (density) gram per centimeter 3 | HB (hardness) | δ μ(tensile strength) kilogram/millimeter 2 |
| Ferrous alloy part acid bronze alloy part | 7.0 7.0～7.1 | 222 161 | 63 45 |
Annotate: above data are the mean value of three samples.
The result of metallographic observation shows existing tangible counterdiffusion between copper, two kinds of alloys of iron, and the bonding state of two kinds of alloys is good.Fig. 1 is that the photo of the metallographic microstructure at two kinds of different-alloy interfaces (amplifies 100 times.Black is acid bronze alloy one end, and white is ferrous alloy one end).
Claims (1)
1, a kind of copper, iron double metal synchronization device cone ring that is used for automobile gearbox, it is characterized in that partly being made up of acid bronze alloy part and ferrous alloy, used copper, ferroalloy composition (weight %) are respectively Cu-8～10Al-3～4Ni-1～2Fe and Fe-4～6Cu-0.7～0.75C.
