Hmoov metallurgy (Hmoov metallurgy, hu ua PM) yog ib qho kev siv tshuab metallurgical uas cov hmoov hlau (los yog cov hmoov sib tov ntawm cov hmoov hlau thiab cov hmoov tsis yog hlau) yog siv los ua cov khoom siv hlau los yog cov khoom siv los ntawm kev sib sau, sintering lossis kub sib sau.Cov txheej txheem ntawm cov hmoov hlau metallurgy zoo ib yam li cov txheej txheem ntawm cov khoom siv ceramic, yog li tib neeg feem ntau hu ua hmoov metallurgy txoj kev "cermet method".
Nrog rau txoj kev loj hlob sai ntawm txhua qhov chaw ntawm lub neej, ntau yam kev xav tau xws li lub teeb yuag thiab compact tsim, ntau thiab ntau qhov chaw tau dhau los ua ntau thiab ntau dua, ua rau cov hmoov metallurgy molding txheej txheem ntsib ntau cov kev cov nyom.
Nrog rau qhov nce ntawm PM, cov kev cai rau cov txheej txheem yuav tsum nruj dua.Raws li cov khoom tseem ceeb tshaj plaws ntawm cov hmoov metallurgy ib feem ntau lawm kab, cov hmoov sib sau hydraulic xovxwm txiav txim siab qhov zoo ntawm cov hmoov compact thiab txwv txoj kev loj hlob ntawm cov hmoov metallurgy kev lag luam hauv Suav teb..Cov hmoov xovxwm ua haujlwm siab yog cov hmoov sib sau hydraulic xovxwm khoom raws li cov tshuab electro-hydraulic ratio, tab sis nws cov tshuab yog nyob rau hauv lub xeev xauv.
Tam sim no, cov hmoov metallurgy ntau lawm cov nroj tsuag tau qhia cov khoom siv ua hmoov zoo thiab cov kab ntau lawm los ntawm txawv teb chaws, tab sis kev taw qhia ib leeg tsis tuaj yeem daws qhov teeb meem hauv paus.Yog li ntawd, kev ywj pheej ntawm kev tsim cov khoom siv high-tech hmoov kuj yog qhov kev loj hlob loj tshaj plaws hauv kev lag luam hmoov.
Hmoov metallurgy txheej txheem
Kev sib sau yog ib kauj ruam tseem ceeb hauv cov txheej txheem hmoov metallurgy.Lub hom phiaj ntawm kev tsim yog los tsim ib qho kev cog lus nrog ib qho zoo li, qhov loj me, ntom thiab lub zog.Compression molding yog txoj kev yooj yim tshaj plaws.
Cov txheej txheem compression molding muaj cov txheej txheem yooj yim, ua haujlwm siab, thiab yooj yim rau kev tsim khoom.Txawm li cas los xij, qhov kev faib tawm siab ntawm txoj kev no tsis zoo ib yam, yog li qhov ntom ntawm lub cev ntsuab tsis sib xws, thiab kev tawg yog qhov tshwm sim, ua rau cov khoom tsis zoo.
ib.Qhov kev sib tw ntawm kev faib tawm ntom ntom ntiSab siab ua rau muaj kev sib txhuam, uas yuav ua rau lub siab poob qis hauv qhov siab ntawm qhov kev cog lus.
Kev txhim kho kev ntsuas: 1) Txo cov kev sib txhuam, siv cov roj lubricating rau ntawm phab ntsa sab hauv lossis siv cov pwm nrog cov phab ntsa zoo dua qub;
2) Ob txoj kev nias yog siv los txhim kho qhov tsis sib xws ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom;
3) Sim txo qhov siab-inch piv thaum tsim pwm.
b.Demoulding kev ncaj ncees: vim lub elastic expansion ntawm tus poj niam pwm thaum lub sij hawm nias txheej txheem, thaum lub siab raug tshem tawm, lub compact hinder lub elastic contraction ntawm tus poj niam pwm, thiab lub compact yog raug rau radial siab, ua rau lub compact tau txais rov qab shear. kev nyuaj siab thaum lub sij hawm demolding txheej txheem Qee qhov tsis muaj zog ntawm qhov kev cog lus yuav raug puas tsuaj raws li cov lus hais saum toj no.
Kev txhim kho kev ntsuas: Raws li cov qauv, cov khoom yuav tsum tsis txhob nyias-walled, tob thiab nqaim grooves, ntse npoo, me me thiab nyias tus thawj coj thiab lwm cov duab kom ntau li ntau tau.
Los ntawm ob lub ntsiab lus saum toj no, cov lus piav qhia ntxhib ntawm qhov cuam tshuam ntawm ib qho tseem ceeb hauv kev tswj cov txheej txheem molding ntawm cov khoom zoo, tab sis hauv kev siv tswv yim, ntau yam cuam tshuam yog kev sib nrig.Thaum lub sijhawm kev tshawb fawb, nws pom tau tias cov yam ntxwv uas cuam tshuam rau cov khoom zoo tib lub sijhawm yog:
1. Kev cuam tshuam ntawm kev tsim siab ntawm qhov zoo ntawm billet: lub zog nias muaj qhov cuam tshuam ncaj qha rau qhov ceev.Qhov kev poob siab uas twb muaj lawm ua rau delamination thiab tev tawm thaum nias, thiab cov kab nrib pleb muaj nyob ntawm qhov sib cuam tshuam ntawm kev cog lus tom qab demolding.
2. Cov nyhuv ntawm nias ceev ntawm qhov zoo ntawm cov compaction: Thaum lub sij hawm cov hmoov compaction, nias ceev cuam tshuam rau huab cua tawm ntawm lub qhov hws ntawm cov hmoov, thiab ncaj qha cuam tshuam lub uniformity ntawm compact ceev.Qhov sib txawv ntom ntom ntawm lub compact yog qhov loj.Qhov yooj yim dua nws yog tsim cov kab nrib pleb.
3. Lub sij hawm tuav ntawm qhov zoo ntawm lub compact: Thaum lub sij hawm nias, yuav tsum muaj ib tug tsim nyog tuav lub sij hawm nyob rau hauv lub siab tshaj plaws nias, uas yuav ua rau kom qhov ceev ntawm lub compact.
Lub siab tsis siv neeg hmoov metallurgy molding cov cuab yeej tshiab tsim los ntawm Chengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd.
Lub floating template hom composite pwm puag ntawm cov cuab yeej tuaj yeem tswj tau qhov sib xws ntawm cov khoom thiab tus nqi tsim nyog ntawm cov khoom.Nyob rau hauv lub hauv paus ntawm kev txaus siab rau lub siab tas mus li nias, cov txheej txheem taag pressing mechanism ntawm lub tshuab xovxwm yog ntxiv, uas yuav tsis tsuas yog pab raws li ib tug txwv tab sis kuj raws li ib tug ruaj pressing mechanism.Kev tiv thaiv ob txheej ntawm nias thiab nias zoo heev txhim kho cov khoom raug thiab kev ua haujlwm ntau lawm.
