Manufacturing txheej txheem ntawm iav

Peb nyuam qhuav ua ib pawg ntawmtsis yog tus qauv iav, feem ntau yog siv nyob rau hauv lub teb ntawm automation machinery, ces koj puas paub tias peb cov kauj ruam tsim khoom yog dab tsi? Cia kuv qhia koj

Cov txheej txheem ntau lawm ntawm cov iav feem ntau suav nrog cov kauj ruam hauv qab no:

1. Kev npaj tsim:

• Txiav txim siab tsis: raws li cov kev cai tshwj xeeb ntawm cov iav thiab qhov chaw ua haujlwm, txiav txim siab qhov sib kis ntawm cov iav, tus naj npawb ntawm cov hniav, modulus, qhov ntsuas lub voj voog txoj kab uas hla, cov hniav dav thiab lwm yam tsis. Kev suav ntawm cov kev txwv no yuav tsum tau ua raws li lub hauv paus ntsiab lus ntawm kev sib kis ntawm cov tshuab thiab cov qauv tsim, xws li kev txiav txim siab sib kis los ntawm kev sib kis ntawm cov saw hlau, suav cov quab yuam ntawm cov iav hniav raws li lub zog ntawm lub pinion, thiab tom qab ntawd suav cov qauv ntawm cov iav thiab txoj kab uas hla ntawm lub voj voog lub zog ntawm lub zog ntawm lub zog ntawm lub zog ntawm lub zog ntawm lub zog ntawm lub zog thiab lub zog ntawm lub zog. nto.

• Kev xaiv cov khoom siv: Kev xaiv cov khoom siv iav yog qhov tseem ceeb rau kev ua haujlwm thiab kev pabcuam lub neej ntawm cov iav. Cov khoom siv iav feem ntau yog cov pa roj carbon steel nruab nrab (xws li 45 steel), qis thiab nruab nrab carbon alloy steel (xws li 20Cr, 40Cr, 20CrMnTi, thiab lwm yam), rau cov iav tseem ceeb nrog cov kev xav tau siab dua, 38CrMoAlA nitride hlau tuaj yeem xaiv, thiab cov hlau tsis muaj zog sib kis kuj tuaj yeem ua los ntawm cov hlau cam, plywood lossis nylon thiab lwm yam ntaub ntawv.

2. Kev npaj dawb:

• Forging: Thaum lub zog xav tau lub zog siab, hnav tsis kam thiab kev cuam tshuam, feem ntau yog siv forging blanks. Forging tuaj yeem txhim kho lub koom haum sab hauv ntawm cov khoom siv hlau, ua kom nruj dua, thiab txhim kho cov khoom siv ntawm cov iav. Cov dawb paug tom qab forging yuav tsum tau kho nrog isothermal normalizing kom tshem tawm cov residual kev nyuaj siab tshwm sim los ntawm forging thiab roughing, txhim kho lub machinability ntawm cov ntaub ntawv thiab txhim kho cov neeg kho tshuab cov khoom.

• Casting: Rau cov iav loj uas muaj txoj kab uas hla ntau dua 400-600mm, feem ntau blanks yog cam khwb cia. Casting tuaj yeem tsim cov iav nrog cov duab tsis yooj yim, tab sis lub koom haum sab hauv ntawm cov iav cam khwb cia yuav muaj qhov tsis xws li porosity thiab porosity, uas yuav tsum tau kho cua sov tom qab thiab kev siv tshuab los txhim kho nws cov kev ua tau zoo.

• Lwm txoj hauv kev: Rau cov iav me me thiab cov duab nyuaj, cov txheej txheem tshiab xws li precision casting, siab casting, precision forging, hmoov metallurgy, kub dov thiab txias extrusion tuaj yeem siv los tsim cov hniav nyiaj hniav kub nrog cov iav hniav kom txhim kho kev ua haujlwm thiab txuag cov ntaub ntawv raw.

3. Mechanical processing:

• Kev ua cov hniav dawb paug:

• Roughing: ntxhib tig, ntxhib milling thiab lwm yam kev ua ntawm cov hniav dawb paug kom tshem tawm feem ntau ntawm cov npoo, tawm hauv 0.5-1mm ua cov npoo rau kev ua tiav tom ntej. Thaum roughing, nws yog ib qho tsim nyog los xyuas kom meej tias qhov tseeb qhov tseeb thiab qhov chaw roughness ntawm cov hniav dawb paug ua tau raws li qhov yuav tsum tau ua.

• Semi-finishing: semi-finishing tig, semi-finishing milling thiab lwm yam kev ua, kom ntxiv dag zog qhov raug thiab nto zoo ntawm cov hniav dawb paug, npaj rau cov hniav zoo. Thaum lub sij hawm ib nrab tiav, yuav tsum tau them nyiaj mloog mus rau kev tswj lub uniformity ntawm kev ua hauj lwm pub kom tsis txhob muaj ntau tshaj los yog tsawg nyiaj pub.

• Kev Ua tiav: Kev ua kom zoo, zoo milling, sib tsoo thiab lwm yam kev ua ntawm cov hniav dawb huv kom paub meej tias qhov tseeb qhov tseeb, cov duab raug thiab qhov roughness ntawm cov hniav dawb paug raws li cov qauv tsim. Thaum ua tiav, cov cuab yeej ua haujlwm tsim nyog thiab cov cuab yeej yuav tsum raug xaiv los txhim kho kev ua tau zoo thiab kev ua haujlwm zoo.

• Kev ua cov hniav:

• Cov hniav milling: siv disk modulus milling cutter los yog ntiv tes milling cutter milling hniav, belongs rau txoj kev tsim. Lub cutter hniav seem zoo sib xws rau cov duab ntawm cov hniav iav, thiab cov hniav milling tuaj yeem ua cov iav ntawm ntau cov duab, tab sis cov kev ua tau zoo thiab kev ua haujlwm raug tsawg, uas yog tsim rau ib qho me me batch ntau lawm los yog kho.

• Hobbing: Nws belongs rau cov txheej txheem tsim, thiab cov hauv paus ntsiab lus ntawm kev ua haujlwm yog sib npaug rau cov meshing ntawm ib khub ntawm helical gears. Gear hob prototype yog ib qho kauv iav nrog lub kaum ntse ntse loj, vim tias cov hniav me me heev (feem ntau yog cov hniav), cov hniav ntev heev, nyob ib ncig ntawm cov ncej los ua cov kab cab nrog lub me me kauv lub kaum sab xis, thiab tom qab ntawd los ntawm cov qhov thiab cov hniav, nws dhau los ua ib lub hob nrog txiav ntug thiab rov qab lub kaum sab xis. Iav hobbing yog tsim rau txhua yam ntawm cov khoom loj, ua cov khoom nruab nrab zoo sab nraud cylindrical iav thiab cab iav.

• Iav shaper: Nws kuj yog ib hom kev tsim cov txheej txheem ua. Thaum siv lub iav shaper, lub iav shaper cutter thiab lub workpiece yog sib npaug rau cov meshing ntawm ib khub ntawm cylindrical iav. Lub reciprocating tsab ntawv tsa suab ntawm lub iav shaper yog lub ntsiab lus ntawm lub iav shaper, thiab lub voj voog ua los ntawm lub iav shaper thiab lub workpiece raws li ib qho kev faib ua feem yog pub mov ntawm lub iav shaper. Iav shaper yog tsim rau txhua yam ntawm cov khoom loj, ua cov khoom nruab nrab zoo sab hauv thiab sab nraud cylindrical zog, ntau lub zog sib txuas thiab cov khib nyiab me me.

Shaving: Shaving yog ib txoj hauv kev siv ntau tshaj plaws rau cov hniav uas tsis muaj zog hauv ntau lawm. Lub hauv paus ntsiab lus ua haujlwm yog siv cov shaving cutter thiab cov iav kom ua tiav rau kev txav meshing dawb, nrog kev pab ntawm cov txheeb ze plam ntawm ob, kom chais cov chips zoo heev los ntawm tus hniav nto los txhim kho qhov tseeb ntawm cov hniav. Cov hniav shaving kuj tuaj yeem tsim cov hniav nruas los txhim kho txoj hauj lwm ntawm qhov chaw sib cuag ntawm cov hniav.

Iav sib tsoo: yog ib txoj kev ntawm cov hniav profile tiav, tshwj xeeb tshaj yog rau cov iav hardened, feem ntau tsuas yog txoj kev ua tiav. Iav sib tsoo tuaj yeem sib tsoo nrog lub log sib tsoo, kuj tuaj yeem sib tsoo nrog conical sib tsoo log lossis disc sib tsoo log. Iav sib tsoo machining precision yog siab, nto roughness tus nqi yog me me, tab sis qhov ntau lawm efficiency yog tsawg, siab nqi.

4. Kev kho cua sov:

• Kev kho cua sov dawb: Npaj ua ntej kev kho cua sov ua ntej thiab tom qab ua cov hniav dawb huv, xws li normalizing lossis tempering, lub hom phiaj tseem ceeb yog tshem tawm cov kev ntxhov siab uas tshwm sim los ntawm forging thiab roughing, txhim kho lub machinability ntawm cov khoom thiab txhim kho cov khoom siv kho tshuab.

• Kev kho cua sov ntawm cov hniav: Tom qab ua cov hniav zoo nkauj, txhawm rau txhim kho cov tawv nqaij thiab hnav tsis kam ntawm cov hniav, carburizing hardening, high-frequency induction cua sov hardening, carbonitriding thiab nitriding cua sov txheej txheem yog feem ntau nqa tawm.

5. Kev ua cov hniav kawg: cov hniav kawg ntawm cov iav yog ua tiav los ntawm kev sib tw, chamfering, chamfering thiab deburring. Cov hniav kawg machining yuav tsum tau nqa tawm ua ntej lub iav quenching, feem ntau tom qab dov (interpolation) cov hniav, ua ntej shaving npaj cov hniav kawg machining.

6. Kev soj ntsuam zoo: ntau yam tsis sib xws ntawm cov iav raug kuaj, xws li cov hniav zoo nkauj, cov hniav txhuam hniav, cov hniav kev taw qhia, cov hniav tuab, qhov ntev ntev, kev khiav hauj lwm, thiab lwm yam, kom ntseeg tau tias qhov precision thiab zoo ntawm cov iav ua tau raws li cov qauv tsim. Cov txheej txheem kuaj pom muaj xws li kev ntsuas phau ntawv nrog cov cuab yeej ntsuas thiab ntsuas qhov tseeb nrog cov cuab yeej ntsuas iav.
