12L14 steel phaj: tus sawv cev zoo tshaj plaws ntawm kev ua tau zoo siab txiav hlau dawb

Hauv kev lag luam niaj hnub no, kev ua tau zoo ntawm cov hlau cuam tshuam ncaj qha rau qhov zoo thiab kev tsim khoom ntawm cov khoom. Raws li cov hlau ua haujlwm siab, 12L14 steel phaj tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov tshuab precision, cov khoom siv tsheb, cov khoom siv hluav taws xob thiab lwm yam lag luam nrog nws cov tshuaj lom neeg tshwj xeeb thiab cov yam ntxwv ua tiav zoo heev.

1. Cov tshuaj lom neeg muaj pes tsawg leeg: lub hauv paus ntawm kev ua tau zoo heev

Qhov kev ua tau zoo tshwj xeeb ntawm 12L14 steel phaj yog los ntawm nws cov tshuaj lom neeg sib xyaw ua ke. Cov pa roj carbon raug tswj hwm nruj me ntsis ntawm ≤0.15%, uas ua kom ntseeg tau tias cov khoom siv tawv thiab ductility; cov manganese ntau dua (0.85 - 1.15%) ua rau lub zog thiab hnav tsis kam; thiab cov silicon cov ntsiab lus yog ≤0.10%, uas txo qhov cuam tshuam ntawm cov khoom tsis huv rau kev ua tau zoo. Tsis tas li ntawd, ntxiv phosphorus (0.04 - 0.09%) thiab sulfur (0.26 - 0.35%) txhim kho kev ua tau zoo ntawm kev txiav; ntxiv cov txhuas (0.15 - 0.35%) ntxiv txo qhov kev tiv thaiv txiav, ua rau cov chips yooj yim tawg, thiab txhim kho kev ua haujlwm thiab lub neej ntawm cov cuab yeej.

II. Cov txiaj ntsig ntawm kev ua tau zoo: xav txog ob qho tib si kev ua tiav thiab daim ntawv thov

1. Kev ua tau zoo heev ntawm kev txiav: 12L14 steel phaj tuaj yeem hu ua "tus khub zoo rau kev ua cov khoom siv kho tshuab". Nws qhov kev tiv thaiv txiav yog ntau dua 30% qis dua li cov hlau ib txwm. Nws tuaj yeem ua tiav kev txiav ceev ceev thiab kev ua cov khoom noj loj. Nws ua tau zoo ntawm cov tshuab dhos tsis siv neeg, CNC tshuab cuab yeej thiab lwm yam khoom siv, ua rau lub voj voog ua tiav luv dua thiab txo cov nqi tsim khoom.

2. Qhov zoo ntawm qhov chaw: Qhov tiav ntawm qhov chaw ntawm cov hlau 12L14 uas tau ua tiav tuaj yeem ncav cuag Ra0.8-1.6μm. Tsis tas yuav tsum tau kho polishing tom qab. Electroplating, txau thiab lwm yam txheej txheem kho qhov chaw tuaj yeem ua tau ncaj qha, uas tsis yog tsuas yog ua kom pom tseeb ntawm cov khoom, tab sis kuj txhim kho kev ua haujlwm ntau lawm.

3. Cov khoom siv kho tshuab ruaj khov: Lub zog tensile ntawm cov hlau phaj yog nyob rau hauv qhov ntau ntawm 380-460MPa, qhov elongation yog 20-40%, qhov cross-sectional shrinkage yog 35-60%, thiab qhov hardness yog nruab nrab (kub-dov xeev 121HB, txias-dov xeev 163HB). Nws tuaj yeem tswj cov khoom siv kho tshuab ruaj khov nyob rau hauv ntau yam kev ua haujlwm thiab ua tau raws li qhov xav tau siv ntawm ntau qhov xwm txheej.

4. Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: 12L14 steel phaj nruj me ntsis ua raws li cov qauv kev tiv thaiv ib puag ncig thoob ntiaj teb, tau dhau EU SGS daim ntawv pov thawj ib puag ncig thiab Swiss daim ntawv pov thawj ib puag ncig, tsis muaj cov tshuaj lom neeg xws li txhuas thiab mercury, thiab yog nyob rau hauv kab nrog kev txhim kho ntawm kev tsim khoom ntsuab niaj hnub.

III. Cov Lus Qhia thiab Cov Qauv: Hloov kho rau ntau yam kev xav tau

Cov phaj hlau 12L14 muaj ntau yam kev siv tau hauv cov lus qhia. Cov phaj hlau kub dov tuab yog 1-180 hli, cov phaj hlau txias dov tuab yog 0.1-4.0 hli, qhov dav ib txwm yog 1220 hli, thiab qhov ntev yog 2440 hli, uas tuaj yeem hloov kho tau raws li cov neeg siv khoom xav tau. Hauv cov qauv, nws sib xws nrog cov qauv thoob ntiaj teb xws li AISI 12L14 hauv Tebchaws Meskas, SUM24L hauv JIS G4804 hauv Nyiv Pooj, thiab 10SPb20 (1.0722) hauv DIN EN 10087 hauv Lub Tebchaws Yelemees, ua kom ntseeg tau tias muaj kev hloov pauv thiab kev sib pauv ntawm cov khoom hauv kev lag luam thoob ntiaj teb.

IV. Cov teb thov: Txhawb kom muaj kev txhim kho kev lag luam

1. Kev tsim tsheb: siv los tsim cov khoom siv precision xws li gearbox iav shafts, roj injector tsev, sensor brackets, thiab lwm yam, kom ntseeg tau tias kev ua haujlwm zoo ntawm cov tsheb fais fab thiab cov tshuab tswj hluav taws xob.

2. Cov khoom siv hluav taws xob thiab cov cuab yeej ua haujlwm raug: Nws yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv siab xws li cov iav saib, cov cuab yeej phais mob, thiab cov ntsia hlau kho qhov muag, pab cov khoom siv hluav taws xob thiab cov cuab yeej ua haujlwm raug kom ua tiav qhov me me thiab qhov raug siab.

3. Kev tsim khoom siv tshuab: Nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom xws li hydraulic valve cores, bearing retainers, thiab connecting pins ntawm cov khoom siv automation, thiab txhim kho kev ruaj khov thiab kev siv tau ntev ntawm cov khoom siv tshuab.

4. Cov khoom siv niaj hnub thiab cov khoom siv rau cov neeg siv khoom: Nws yog siv dav hauv cov khoom siv rooj tog zaum zoo, xauv, cov khoom siv hluav taws xob me me thiab lwm yam khoom, xav txog kev ua haujlwm thiab kev zoo nkauj.

Ua ib lub hlau zoo uas muaj kev ua tau zoo, yooj yim ua, thiab kev tiv thaiv ib puag ncig, 12L14 steel phaj yog tsav tsheb rau kev lag luam niaj hnub no kom txav mus rau kev ua haujlwm siab, kev ua haujlwm raug, thiab ntsuab nrog nws cov txiaj ntsig tshwj xeeb, thiab tau dhau los ua lub hauv paus tseem ceeb rau ntau lub lag luam kom ua tiav cov thev naus laus zis thiab kev tsim khoom tshiab.
