Hauv kev lag luam kev lag luam, cov hniav txhuam hniav yeej ib txwm yog qhov tseem ceeb cuam tshuam rau kev tsim khoom thiab cov khoom zoo. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov txheej txheem, kev tshawb fawb ntawmindustrial hniavabrasion mechanism tau dhau los ua ntau thiab ntau qhov tob, txhawm rau nrhiav cov ntsiab lus tseem ceeb los txuas ntxiv lub neej kev pabcuam ntawm cov hniav.
Muaj ntau yam laj thawj rau cov hniav abrasion, feem ntau suav nrog txhua yam hnav, thermal hnav, tshuaj hnav thiab diffusion hnav. Mechanical abrasion feem ntau yog tshwm sim los ntawm cov khoom nyuaj hauv cov khoom siv ua haujlwm los ua cov grooves ntawm cov hniav, thiab hom kev puas tsuaj yog qhov tshwj xeeb tshaj yog thaum txiav ntawm qhov qis qis. Thermal abrasion yog vim muaj ntau cov cua sov tsim thaum lub sij hawm txiav, ua rau cov yas deformation ntawm cov hniav puas los yog thermal tawg. Cov tshuaj siv tshuaj yog cov pa oxygen hauv huab cua ntawm qhov kub thiab txias thiab cov tshuaj tiv thaiv ntawm cov khoom siv hniav, tsim cov khoom sib txuas uas tsis muaj zog, cov nti tawm mus, ua rau cov hniav puas. Diffusion abrasion, ntawm qhov tod tes, yog tias thaum lub sij hawm txiav cov txheej txheem, cov tshuaj nyob rau ntawm qhov chaw ntawm lub workpiece thiab cov hniav abrasion diffuse nrog ib leeg nyob rau hauv cov khoom ntawm lub xeev, hloov cov compositional qauv ntawm cov hniav thiab ua rau nws nto txheej. yooj yim.
Rau cov txheej txheem hnav no, cov kws tshawb fawb tau npaj ntau txoj hauv kev los txuas ntxiv lub neej kev pabcuam ntawm cov hniav puas. Ua ntej ntawm tag nrho cov, tsim nyog xaiv cov ntaub ntawv hniav yog qhov tseem ceeb. Raws li cov yam ntxwv ntawm cov khoom ua tiav thiab kev txiav, xaiv cov khoom siv nrog cov tawv tawv txaus, hnav tsis kam thiab toughness tuaj yeem txo qhov kev puas tsuaj. Piv txwv li, thaum machining nyuaj-rau-txiav cov ntaub ntawv nrog ib tug loj nyiam mus harden, cov hniav cov ntaub ntawv uas muaj zog tiv taus txias vuam thiab muaj zog tsis kam mus rau diffusion yuav tsum tau xaiv.
Secondly, optimizing hniav geometry tsis kuj yog ib qho tseem ceeb txhais tau tias ntawm ncua kev pab cuam lub neej. Tsim nyog lub kaum sab xis thiab cov hniav zoo tuaj yeem txo qhov txiav quab yuam thiab txiav cov cua sov, thiab txo cov hniav puas. Piv txwv li, qhov tsim nyog txo qis ntawm cov kaum sab xis pem hauv ntej thiab nraub qaum thiab siv qhov loj dua qhov tsis zoo ntawm ntug inclination tuaj yeem txo qhov hnav ntawm ntug txiav. Nyob rau tib lub sijhawm, kev sib tsoo lub chamfer tsis zoo lossis ntug arc kuj tuaj yeem txhim kho lub zog ntawm lub hau ntawm cov hniav thiab tiv thaiv chipping.
Tsis tas li ntawd, kev xaiv tsim nyog ntawm kev txiav ntau npaum li cas thiab kev siv cov roj nplua nyeem txias kuj yog ib txoj hauv kev zoo los txuas lub neej ntawm cov hniav. Qhov tob ntawm kev txiav thiab pub yog loj heev, txiav quab yuam nce, thiab cov hniav abrasion yog ceev. Yog li ntawd, nyob rau hauv lub premise ntawm ua kom paub tseeb efficiency, txiav tus nqi yuav tsum tau minimized. Nyob rau tib lub sijhawm, kev siv cov roj cua txias tuaj yeem nqus tau thiab tshem tawm feem ntau ntawm cov cua sov hauv cheeb tsam txiav, txhim kho cov cua sov dissipation, txo qhov kub ntawm cov hniav thiab workpiece, yog li txo cov hniav puas.
Thaum kawg, txoj kev ua haujlwm kom raug thiab cov txheej txheem txheej txheem nruj kuj yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Nyob rau hauv cov txheej txheem txiav, cov hniav yuav tsum tau sim ua kom cov hniav tsis dais los yog tsawg dais qhov kev hloov ntawm lub load tam sim ntawd, kom tsis txhob cov hniav vim tsis sib npaug zog thiab tawg. Nyob rau tib lub sijhawm, txhawm rau xyuas kom meej tias cov txheej txheem txheej txheem muaj qhov zoo rigidity, txo kev vibration, kuj tseem tuaj yeem ua kom ntev lub neej kev pab cuam ntawm cov hniav.
Hauv cov ntsiab lus, cov ntsiab lus tseem ceeb los txuas ntxiv kev pab cuam lub neej ntawm cov khoom siv muaj xws li tsim nyog xaiv cov ntaub ntawv hniav, optimization ntawm cov hniav geometry tsis, tsim nyog xaiv ntawm txiav ntau npaum li cas, kev siv cov coolant lubricants thiab txoj kev khiav hauj lwm kom raug thiab txheej txheem rigidity. Nrog rau kev sib sib zog nqus mus rau qhov kev tshawb fawb ntawm cov txheej txheem ntawm cov hniav abrasion, nws ntseeg tau tias cov thev naus laus zis tshiab thiab cov txheej txheem yuav tshwm sim yav tom ntej, txhaj tshuaj tshiab tseem ceeb rau hauv kev tsim kho kev lag luam.
Tom qab ntawd, Peb yuav hloov kho cov ntaub ntawv txuas ntxiv, thiab koj tuaj yeem nrhiav cov ntaub ntawv ntxiv ntawm peb lub vev xaib (passiontool.com) blog.
Tau kawg, koj tuaj yeem them sai sai rau peb Cov Kev Tshaj Lij Tshaj Lij Tshaj Tawm:
