Cov txheej txheem molding hmoov metallurgy

Hmoov hlau metallurgy (Hmoov metallurgy, hu ua PM) yog ib txoj kev siv tshuab metallurgy uas siv cov hmoov hlau (lossis sib xyaw ntawm cov hmoov hlau thiab cov hmoov tsis yog hlau) ua cov khoom siv raw los tsim cov khoom hlau lossis cov ntaub ntawv los ntawm kev tsim, sintering lossis kub. Cov txheej txheem tsim cov hmoov metallurgy zoo ib yam li cov txheej txheem tsim cov khoom siv ceramic, yog li cov neeg feem ntau hu cov txheej txheem hmoov metallurgy "cermet method".
Nrog rau 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 dua thiab nyuaj dua, ua rau cov txheej txheem hmoov metallurgy molding ntsib ntau yam kev cov nyom.
Nrog rau kev nce ntxiv ntawm PM, cov kev cai rau cov txheej txheem yuav tsum nruj dua. Raws li cov khoom siv tseem ceeb tshaj plaws ntawm cov hmoov metallurgy qhov ntau lawm kab, lub tshuab hydraulic ua hmoov txiav txim siab qhov zoo ntawm cov hmoov compact thiab txwv tsis pub txoj kev loj hlob ntawm kev lag luam hmoov metallurgy hauv Suav teb. . Lub tshuab hydraulic ua haujlwm siab yog cov khoom siv hydraulic ua hmoov raws li electro-hydraulic piv technology, tab sis nws cov thev naus laus zis nyob rau hauv lub xeev xauv.
Tam sim no, cov chaw tsim khoom hmoov metallurgy loj dua tau tsim cov khoom siv tsim hmoov thiab cov kab tsim khoom los ntawm txawv teb chaws, tab sis kev qhia ib leeg tsis tuaj yeem daws qhov teeb meem tseem ceeb. Yog li ntawd, kev tsim kho ywj pheej ntawm cov khoom siv tsim hmoov thev naus laus zis siab kuj yog qhov kev loj hlob loj tshaj plaws hauv kev lag luam hmoov.

Cov txheej txheem tsim cov hmoov hlau metallurgy
Kev tsim yog ib kauj ruam tseem ceeb hauv cov txheej txheem hmoov metallurgy. Lub hom phiaj ntawm kev tsim yog los tsim cov khoom me me nrog qee yam duab, qhov loj me, qhov ceev thiab lub zog. Compression molding yog txoj kev tsim yooj yim tshaj plaws.
Txoj kev molding compression muaj cov txheej txheem yooj yim, ua haujlwm tau zoo, thiab yooj yim rau kev tsim khoom tsis siv neeg. Txawm li cas los xij, qhov kev faib tawm ntawm txoj kev no tsis sib xws, yog li qhov ceev ntawm lub cev ntsuab tsis sib xws, thiab tawg yooj yim tshwm sim, ua rau cov khoom tsis zoo.
a. Qhov sib npaug ntawm qhov sib faib ntawm qhov ceev ntawm lub compact: Vim tias lub cev hmoov ntws mus rau txhua qhov kev taw qhia tom qab raug kev nyuaj siab hauv lub pwm, nws ua rau muaj qhov siab ntawm sab perpendicular rau phab ntsa ntawm lub pwm. Qhov siab ntawm sab ua rau muaj kev sib txhuam, uas yuav ua rau muaj qhov siab poob qis hauv qhov siab ntawm lub compact.
Kev ntsuas kev txhim kho: 1) Txo kev sib txhuam, siv roj nplua nyeem rau ntawm phab ntsa sab hauv lossis siv pwm nrog phab ntsa sab hauv du dua;
2) Kev nias ob txoj kev yog siv los txhim kho qhov tsis sib xws ntawm qhov sib faib ceev ntawm cov compacts ntsuab;
3) Sim txo qhov sib piv ntawm qhov siab thiab txoj kab uas hla thaum tsim pwm.
b. Kev ua kom zoo: vim yog qhov nthuav dav ntawm cov pwm poj niam thaum lub sijhawm nias, thaum lub siab raug tshem tawm, lub compact cuam tshuam qhov elastic contraction ntawm cov pwm poj niam, thiab lub compact raug rau lub zog radial, ua rau lub compact tau txais kev ntxhov siab rov qab thaum lub sijhawm demolding Qee qhov chaw tsis muaj zog ntawm lub compact yuav raug rhuav tshem nyob rau hauv qhov kev ntxhov siab shear saum toj no.
Kev ntsuas kev txhim kho: Hais txog cov qauv, cov khoom yuav tsum zam cov phab ntsa nyias, cov qhov tob thiab nqaim, cov npoo ntse, cov qhov me thiab nyias thiab lwm yam duab ntau li ntau tau.
Los ntawm ob lub ntsiab lus saum toj no, ib qho kev piav qhia txog qhov cuam tshuam ntawm ib qho tseem ceeb hauv cov txheej txheem tswj kev txhaj tshuaj rau cov khoom zoo, tab sis hauv kev siv ua haujlwm, ntau yam cuam tshuam yog sib koom ua ke. Thaum lub sijhawm tshawb fawb, nws pom tias cov yam ntxwv uas cuam tshuam rau cov khoom zoo tib lub sijhawm yog:
1. Qhov cuam tshuam ntawm kev tsim lub zog rau qhov zoo ntawm billet: lub zog nias muaj qhov cuam tshuam ncaj qha rau qhov ceev. Qhov poob siab uas twb muaj lawm ua rau delamination thiab tev tawm thaum lub sijhawm nias, thiab muaj cov kab nrib pleb ntawm qhov sib txuas ntawm lub compact tom qab demolding.
2. Qhov cuam tshuam ntawm qhov ceev nias rau qhov zoo ntawm lub compact: Thaum lub sijhawm compact hmoov, qhov ceev nias cuam tshuam rau cov pa tawm ntawm cov qhov hws ntawm cov hmoov, thiab ncaj qha cuam tshuam rau qhov sib xws ntawm qhov ceev ntawm compact. Qhov sib txawv ntawm qhov ceev ntawm lub compact yog qhov loj heev. Qhov yooj yim dua los tsim cov kab nrib pleb.
3. Qhov cuam tshuam ntawm lub sijhawm tuav rau qhov zoo ntawm lub compact: Thaum lub sijhawm nias, yuav tsum muaj lub sijhawm tuav kom tsim nyog nyob rau hauv qhov siab tshaj plaws ntawm kev nias, uas tuaj yeem ua rau qhov ceev ntawm lub compact ntau ntxiv.

Cov khoom siv ua hmoov metallurgy molding tshiab uas Chengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. tsim los ua cov khoom siv tshiab hauv tsev uas sib xyaw cov txiaj ntsig ntawm cov tshuab nias thiab CNC servo hydraulic presses.
Lub hauv paus pwm sib xyaw ua ke ntawm cov khoom siv tuaj yeem tswj tau qhov sib xws ntawm cov khoom thiab qhov nrawm ntawm cov khoom. Raws li kev txaus siab rau qhov kev nias siab tas li, lub tshuab nias ruaj khov ntawm lub tshuab nias tau ntxiv, uas tsis yog tsuas yog ua qhov txwv xwb tab sis kuj yog lub tshuab nias ruaj khov. Kev tiv thaiv ob txheej ntawm kev nias thiab kev nias zoo heev txhim kho qhov tseeb ntawm cov khoom thiab kev ua haujlwm ntau lawm.
