Kho ntawm cov roj hmab extruder ntsia hlau
1. Yuav tsum tau txiav txim siab raws li lub taub hau tiag tiag ntawm lub taub hau, thiab cov hlau sab nraud ntawm cov ntsia hlau tshiab yuav tsum tau muab raws li cov kev tshem tawm ib txwm muaj nrog cov thoob.
2. Tom qab cov xov saum npoo uas hla ntawm cov ntsia hlau hnav tau kho yog kho, hnav kom muaj zog, thiab tom qab ntawd av. Txoj kev no feem ntau yog cov txheej txheem thiab kho los ntawm cov kws tshaj lij kev txau, thiab tus nqi yog tsawg.
3. Overlay Vuam hnav-resistant alloy ntawm xov ntawm cov ntsia hlau hnav. Raws li cov degree ntawm ntsia hlau hnav, surfacing vuam yog 1 ~ 2 hli tuab, thiab tom qab ntawd lub hau ntswj yog av thiab ua tiav kom loj. Qhov no hnav-resistant alloy yog tsim cov khoom xws li C, V, V, V, W thiab B, uas nce cov coj tawm thiab corrosion tsis kam ntawm ntsia hlau. Kev tshaj lij surfacing muaj cov nqi siab rau hom kev ua no, thiab feem ntau tsis tshua muaj siv tshwj tsis yog cov kev cai tshwj xeeb rau cov ntsia hlau.
4. Hard chrome plating kuj tseem siv tau los kho cov ntsia hlau. Chromium kuj yog ib qho kev hnav-resistant thiab corrosion-resistant hlau, tab sis lub zog chrome txheej yog yooj yim rau kev poob.
Kho ntawm roj hmab extruder chim
Lub puab sab hauv hardness ntawm lub thoob yog siab tshaj qhov ntawm cov ntsia hlau, thiab nws puas tsuaj yog tom qab ntawm cov ntsia hlau. Qhov ntsuas ntawm lub thoob yog qhov nce nyob rau hauv lub taub sab hauv qab vim hnav thiab rhuav sijhawm. Ntawm no yog kho nws:
1. Yog hais tias txoj kab uas hla ntawm lub thoob dej nce ntxiv vim tias muaj qee qhov nitrrived txheej, thiab tom qab ntawd lub tshuab raj tshiab tuaj yeem npaj raws li cov kab no.
2. Lub inner inner ntawm lub thoob yog machined thiab trimmed kom rov cam cov alloy, qhov tuab yog nruab nrab ntawm 1 ~ 2 hli, thiab tom qab ntawd ua tiav kom loj.
3. Nyob rau hauv ib txwm muaj xwm txheej, homogenization seem ntawm lub thoob ris sai sai. Seem no (5 ~ 7 D qhov ntev) tuaj yeem txiav los ntawm boring, thiab tom qab ntawd nruab nrog nitrided alloy hlau bushing. Txoj kab uas hla ntawm lub qhov sab hauv yog hais txog qhov taub ntawm cov ntsia hlau. Qhov kev txiav txim siab zoo li qub yog ua tiav thiab npaj tau.
Nws tau hais txog ntawm no tias ob qhov tseem ceeb ntawm cov ntsia hlau thiab lub thoob, ib qho yog ib lub qhov uas muaj qhov sib cav me me. Lawv cov machining thiab cov txheej txheem kho cua sov yog qhov nyuaj dua, thiab nws yog qhov nyuaj rau kom paub tseeb. Cov. Yog li ntawd, txawm tias kho los yog hloov cov chaw tshiab tom qab hnav ob qho no yuav tsum tau kev txheeb xyuas ob qho los ntawm kev saib xyuas kev lag luam. Yog tias tus nqi kho yog qis dua tus nqi ntawm hloov lub hau ntswj tshiab, nws yog txiav txim siab kho nws. Qhov no tsis tas yuav yog txoj cai xaiv. Qhov kev sib piv ntawm cov nqi kho thiab tus nqi hloov tau tsuas yog ib qho. Tsis tas li ntawd, nws nyob ntawm qhov sib piv ntawm cov nqi kho thiab siv cov ntsia hlau tom qab kho tau tus nqi thiab lub sijhawm siv cov ntsia hlau hloov tshiab. Nws yog kev lag luam los txais yuav cov txheej txheem nrog me me piv, uas yog qhov tseeb xaiv.
4. Cov ntaub ntawv rau ntsia hlau thiab chim rau tsim
Screws thiab ua cov thawv. Tam sim no, cov khoom siv uas nquag siv nyob rau hauv Suav teb yog 45, 40CR thiab 38Croala.
