Hlau txhaj molding⎮Hmoov metallurgy⎮Txog Peb

• Powder forming yog theem ob ntawm hmoov metallurgy. Nws yog ib txoj hauv kev uas cov hmoov xoob tau ua rau hauv cov pob zeb uas muaj qee yam zoo li, qhov loj me, ntom thiab lub zog.

• Hmoov los ntawm cov txheej txheem tsim kom tau txais cov duab thiab lub zog ntawm lub cev hmoov, hu ua compact.

Muaj ntau txoj hauv kev ntawm cov hmoov sib sau, ntxiv rau cov txheej txheem molding zoo tib yam, lwm tus raug cais raws li kev tsim tshwj xeeb. Tuag txoj kev yog txoj kev yooj yim tshaj plaws.

tsis muaj xovxwm tsim - pulp casting - xoob sintering

Cov txheej txheem hauv qab no yog siv los tsim cov ntaub ntawv: siab, tuag, kub, isostatic, dov, centrifugal, extrusion, thiab tawg.

• Cov txheej txheem tsim tshwj xeeb;

• ib txwm molding;

• hmoov pretreatment;

• kev xav kev tawm tsam

Powder pretreatment muaj annealing, tshuaj ntsuam, sib tov, granulating, thiab ntxiv lubricants, thiab lwm yam.

Ordinary hmoov tuag forming

Tuag forming yog cov txheej txheem siv hmoov ntau tshaj plaws. Nws hais txog cov txheej txheem ntawm kev thauj cov hmoov sib tov sib xyaw rau hauv cov pwm kaw hauv ib qho nyiaj ntawm chav tsev kub, thiab tom qab ntawd nias nws mus rau hauv ib lub billet nrog ib qho chaw siab los ntawm ib lub xovxwm.

Txoj kev tsim no feem ntau muaj cov kauj ruam hauv qab no: hnyav hmoov, txhaws hmoov, nias, tuav lub siab thiab stripping.

Txoj cai ntawm molding

(1) Siv cov pwm los muab cov hmoov rau daim ntawv xav tau.

(2) Muab lub cev ntawm nws qhov loj me.

(3) Qhia kom meej lub billet qhov tsim nyog porosity thiab hom porosity.

(4) Ua kom lub cev muaj zog thiab ntom ntom rau kev tuav.

Nias txoj kev

Unidirectional nias: lub concave tuag thiab qis punch tsis txav, thiab lub punch sab sauv yog unidirectional pressurized.

Ob txoj kev ua ntejssing: lub concave tuag yog tsau, thiab lub Upper thiab qis punch yog nias tib lub sij hawm nrog sib npaug thiab opposite pressures.

Floating nias: qis punch yog tsau, concave tuag yog kev txhawb nqa los ntawm cov springs, lub tog raj kheej, lub tog raj kheej, thiab lwm yam, thiab tuaj yeem ntab tom qab kev ntxhov siab.

Nias txheej txheem

Cov txheej txheem nias tuaj yeem muab faib ua plaub theem:

(1) Cov hmoov nplej txav, qhov pores txo, thiab cov khoom sib sib zog nqus;

(2) Cov hmoov yog nyem kom nruj, thiab cov khoom me me tau ntim rau hauv qhov sib txawv ntawm cov khoom loj, thiab cov khoom pib deform;

(3) Lub concave thiab convex ib feem ntawm qhov chaw ntawm cov hmoov particle yog nias thiab meshed mus rau hauv ib tug ruaj khov lub xeev;

(4) Kev ua hauj lwm nyuaj ntawm cov hmoov hmoov mus rau lub xeev txwv, ntxiv zog, cov hmoov hmoov raug puas tsuaj thiab crystallization yog refined.

Cov nyhuv ntawm hmoov purity

Vim muaj cov txheej txheem sib txawv ntawm cov hmoov ua, qhov purity ntawm cov hmoov tsis zoo ib yam, thiab cov hmoov muaj qee yam ntawm impurities. Cov impurities nyob rau hauv cov hmoov feem ntau yog nyob rau hauv daim ntawv ntawm hlau oxides.

Cov hmoov hlau oxide feem ntau yog tawv thiab nkig, thiab feem ntau yog muab faib rau saum npoo ntawm cov hmoov hlau, uas ua rau kom cov xovxwm tsis kam thiab ua rau cov xovxwm tsis zoo.

Manufacturability ntawm hmoov sib sau qhov chaw qauv

1. Txhawm rau ua kom cov pwm tsim thiab compaction yooj yim dua, sim xaiv qhov ncaj ncaj, symmetrical tsim kom tsis txhob muaj qhov txawv txav hauv ntu thiab nqaim grooving, spherical nto, thiab lwm yam.

2. Zam cov phab ntsa nyias hauv zos los pab txhawb cov hmoov sib tov thiab tiv thaiv cov kab nrib pleb.

3. Tsis txhob grooves thiab qhov nyob rau sab phab ntsa kom yooj yim compaction los yog txo cov seem seem.

4. Tsis txhob nce qhov ntu ntu ntu raws li cov kev taw qhia nias kom yooj yim rau compaction. Lub kaum sab xis yuav tsum tau sib npaug ntawm qhov sib txuas ntawm txhua phab ntsa kom yooj yim compaction thiab tsis txhob muaj kev ntxhov siab.

Powder Forming Component

Thawj hom ntawm qhov chaw: unidirectional nias, nyias phab ntsa, arbitrary zoo, ib lub rooj (phab ntsa thickness feem ntau mus txog 6.35mm)

Qhov thib ob hom: ib feem ntawm lub rooj, txhua qhov siab thiab cov duab, yuav tsum yog bidirectional nias qhov chaw.

Ntu III: Ib feem ntawm ob lub rooj, ntawm qhov siab thiab cov duab, uas yuav tsum tau nias ntawm ob qho tib si

Qhov thib plaub ntawm qhov chaw: ntau lub rooj, txhua qhov siab thiab cov duab, yuav tsum siv ntau qhov tuag stamping bidirectional nias qhov chaw
