Kho cov roj hmab extruder ntsia hlau
1. Lub twisted ntsia hlau yuav tsum tau txiav txim siab raws li qhov tseeb sab hauv txoj kab uas hla ntawm lub thoob, thiab sab nraud txoj kab uas hla ntawm cov ntsia hlau tshiab yuav tsum tau muab raws li ib txwm clearance nrog lub chim.
2. Tom qab cov xov nto nrog qhov txo txoj kab uas hla ntawm cov ntsia hlau hnav yog kho, hnav-resistant alloy yog thermally sprayed, thiab tom qab ntawd hauv av kom loj.Cov txheej txheem no feem ntau ua tiav thiab kho los ntawm lub Hoobkas kev tshaj lij, thiab tus nqi kuj tsawg.
3. Overlay welding hnav-resistant alloy ntawm cov xov ib feem ntawm cov ntsia hlau hnav.Raws li qib ntawm cov ntsia hlau hnav, nto vuam yog 1 ~ 2 hli tuab, thiab tom qab ntawd cov ntsia hlau yog hauv av thiab ua kom loj.Qhov no hnav-resistant alloy yog tsim los ntawm cov ntaub ntawv xws li C, Cr, Vi, Co, W thiab B, uas ua rau kom hnav tsis kam thiab corrosion kuj ntawm cov ntsia hlau.Cov kws tshaj lij surfacing cov nroj tsuag muaj cov nqi siab rau kev ua haujlwm zoo li no, thiab feem ntau tsis tshua siv tshwj xeeb tshwj xeeb rau cov ntsia hlau.
4. Hard chrome plating kuj tuaj yeem siv los kho cov ntsia hlau.Chromium kuj yog ib qho hnav-resistant thiab corrosion-resistant hlau, tab sis cov tawv chrome txheej yog yooj yim dua los poob.
Kho cov roj hmab extruder chim
Lub puab nto hardness ntawm lub thoob yog siab dua li ntawm cov ntsia hlau, thiab nws cov kev puas tsuaj yog tom qab ntawm cov ntsia hlau.Lub scrapping ntawm lub thoob yog qhov nce ntawm lub puab txoj kab uas hla vim hnav thiab rhuav lub sijhawm.Nov yog yuav kho nws li cas:
1. Yog hais tias txoj kab uas hla ntawm lub thoob nce vim hnav, yog tias tseem muaj ib co nitriding txheej, lub puab qhov ntawm lub thoob tuaj yeem ncaj qha dhuav, hauv av mus rau txoj kab uas hla tshiab, thiab tom qab ntawd cov ntsia hlau tshiab tuaj yeem npaj tau raws li qhov no. txoj kab uas hla.
2. Lub puab txoj kab uas hla ntawm lub thoob yog machined thiab trimmed rau re-cam khwb cia hlau, lub thickness yog nyob nruab nrab ntawm 1 ~ 2 hli, thiab ces tag mus rau loj.
3. Raws li qhov xwm txheej ib txwm muaj, seem homogenization ntawm lub thoob hnav sai sai.Ntu no (5 ~ 7D ntev) tuaj yeem txiav los ntawm tho txawv, thiab tom qab ntawd nruab nrog nitrided alloy steel bushing.Txoj kab uas hla ntawm lub puab qhov yog hais txog txoj kab uas hla ntawm cov ntsia hlau.Qhov kev tshem tawm ib txwm haum yog ua tiav thiab npaj.
Nws yog qhov tseem ceeb ntawm no tias ob qhov tseem ceeb ntawm cov ntsia hlau thiab lub thoob, ib qho yog ib txoj hlua khi hlua khi, thiab lwm qhov yog lub qhov nrog qhov me me thiab ntev txoj kab uas hla.Lawv cov txheej txheem machining thiab kev kho cua sov yog qhov nyuaj dua, thiab nws nyuaj rau kev ua kom raug..Yog li ntawd, seb puas yuav kho lossis hloov qhov tshiab tom qab hnav ntawm ob ntu no yuav tsum tau txheeb xyuas los ntawm qhov kev xav ntawm kev lag luam.Yog tias tus nqi kho mob qis dua tus nqi ntawm kev hloov cov ntsia hlau tshiab, nws txiav txim siab kho nws.Qhov no tsis yog qhov kev xaiv zoo.Kev sib piv ntawm tus nqi kho thiab tus nqi hloov pauv tsuas yog ib qho.Tsis tas li ntawd, nws nyob ntawm qhov piv ntawm tus nqi kho thiab lub sijhawm ntawm kev siv cov ntsia hlau tom qab kev kho rau cov nqi hloov thiab lub sijhawm siv cov ntsia hlau tshiab.Nws yog kev lag luam los txais yuav ib lub tswv yim nrog qhov sib piv me me, uas yog qhov kev xaiv raug.
4. Cov khoom siv rau kev tsim cov ntsia hlau thiab chim
Kev tsim cov ntsia hlau thiab cov thoob.Tam sim no, cov khoom siv feem ntau hauv Suav teb yog 45, 40Cr thiab 38CrMoAlA.
