Description
Technical field
The present invention relates to a kind of compressing material of the high-performance for booster.
Background technology
Current a kind of new forming parts technology when manufacturing machine components using Metal Injection Molding, is made
The performances such as intensity, hardness, the abrasion resistance of part can be changed by the component and content of material, existing to use metal powder injection
The component and content of the material of forming technique manufacture machine components make material be difficult to reach that intensity is high, hardness is big, anti-wear performance is good
Requirement.
The content of the invention
The present invention provides a kind of with Machine Components Strength is high, hardness is big, the good advantage of the wearability height for booster
The compressing material of performance.
The technical scheme is that：A kind of compressing material of high-performance for booster, comprises the following steps：Will
Metal dust is fed in the roll gauge rotated by a special funnel, shuts out blank；By annealing, blank is pressed into grain
Degree size is divided into some levels, and the plasticizer of addition improves green strength, controls certain pressure, blank is pressed into pressing mold
Type；The metal dust is aluminium hydroxide, iron powder, sodium metasilicate and titanium.
In a preferred embodiment of the present invention, the certain pressure is 106MPa.
In a preferred embodiment of the present invention, the temperature of the annealing is 300 DEG C.
A kind of compressing material of high-performance for booster of the present invention, with Machine Components Strength is high, hardness greatly,
The good advantage of wearability.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
Wherein, comprise the following steps：Metal dust is fed in the roll gauge rotated by a special funnel, shut out
Blank；By annealing, blank is divided into some levels by granule size, the plasticizer of addition improves green strength, control one
Constant-pressure, by blank in pressing mold it is compressing；The metal dust is aluminium hydroxide, iron powder, sodium metasilicate and titanium.
Further illustrate, the certain pressure is 106MPa, and the temperature of the annealing is 300 DEG C.
Further illustrating, influenceing the factor of pulverulent product sintering quality a lot, mainly the character of body of powder, shaping bar
The condition of part and sintering.The factor of sintering condition include firing rate, sintering temperature and time, cooling velocity, sintering atmosphere and
Sinter pressurization situation etc..(1) the length of the height and time of sintering temperature and time sintering temperature has influence on the hole of sintered body
Gap rate, consistency, intensity and hardness etc..Sintering temperature is too high and overlong time, will reduce properties of product, or even product mistake occur
Burn defect；Sintering temperature is too low or the time is too short, and product can cause hydraulic performance decline because of underburnt.(2) sintering atmosphere powder smelting
The conventional sintering atmosphere of gold has reducing atmosphere, vacuum, nitrogen atmosphere etc..Sintering atmosphere also directly influences the performance of sintered body.
Sintering prevents pressed compact scaling loss and can reduce oxide on surface under reducing atmosphere.If iron-based, copper-based product are frequently with producer coal
Gas decomposes ammonia, and hard alloy, stainless steel are frequently with pure hydrogen.Active metal or refractory metal（Such as beryllium, titanium, zirconium, tantalum）, containing TiC
Hard alloy and stainless steel etc. can use vacuum-sintering.Vacuum-sintering is avoided that the harmful components in atmosphere（H2O、O2、H2）
Deng adverse effect, can also reduce sintering temperature（100~150 DEG C can typically be reduced）.Enter one after post processing finger pressure base sintering
Step processing, post processing is decided whether according to product specific requirement.Conventional post-processing approach have it is multiple pressure, dipping, heat treatment,
Surface treatment and machining etc..The application pressure treatment that multiple pressure is carried out for raising sintered body physical and mechanical properties, including
Finishing and shaping etc..Finishing is the multiple pressure that the size for needed for reaching is carried out, and sintered body is pressed by die finish to improve essence
Degree.Shaping is, to reach multiple pressure that specific surface configuration is carried out, product to be pressed with correcting deformed and drop by sizing die
Low surface roughness value.Multiple pressure is applied to require the preferable product of higher and plasticity, such as iron-based, copper-based product.Heat treatment pair
Sintered body is heated to certain temperature, then by controlling cooling means etc. to handle, the method to improve product properties.At conventional heat
Reason method has quenching, thermo-chemical treatment, thermo-mechanical processi etc., and process is typically similar to dense material.For not being hit
And require that wear-resisting iron-based product can use integral quenching, because the presence of hole can reduce internal stress, can not typically be tempered.
And require that outer hard interior tough iron-based product can be using quenching or carburizing and quenching.Hot forging is to obtain the conventional method of fine and close product, heat
The product crystal grain of forging is tiny, and intensity and toughness are high.The present invention provides a kind of high-performance for booster and is pressed into section bar
Material, has the advantages that Machine Components Strength is high, hardness is big, wearability is good.
The embodiment of the present invention, but protection scope of the present invention is not limited thereto, it is any to be familiar with this area
Technical staff disclosed herein technical scope in, the change or replacement that can be expected without creative work should all be contained
Cover within protection scope of the present invention.Therefore, the protection model that protection scope of the present invention should be limited with claims
Enclose and be defined.
