Deviation thiab tsim txoj kev loj-inch steel kav hauv ntau lawm

Deviation ntawm loj-inch steel kav hauv ntau lawm: Common loj-inch steel yeeb nkab loj ntau yam: txheej kab: 114mm-1440mm phab ntsa thickness: 4mm-30mm. Length: tuaj yeem ua rau ntev ntev lossis ntev ntev raws li cov neeg siv khoom xav tau. Cov kav hlau loj loj tau siv dav hauv ntau yam kev lag luam xws li aviation, aerospace, lub zog, hluav taws xob, tsheb, kev lag luam teeb, thiab lwm yam, thiab yog ib qho tseem ceeb ntawm cov txheej txheem vuam.

Cov txheej txheem tseem ceeb ntawm cov kav hlau loj loj yog: Forging steel: txoj kev ua haujlwm siab uas siv lub zog reciprocating ntawm lub forging rauj lossis lub siab ntawm cov xovxwm los hloov lub billet rau hauv cov duab thiab loj peb xav tau. Extrusion: Nws yog ib txoj hauv kev uas cov hlau muab hlau tso rau hauv lub tog raj kheej kaw extrusion, siv lub siab ntawm ib qho kawg, thiab nyem cov hlau tawm ntawm qhov chaw tuag kom tau txais cov khoom tiav nrog tib lub duab thiab loj. Nws feem ntau yog siv rau hauv kev tsim cov hlau tsis-ferrous hlau. Rolling: Ib txoj kev ua haujlwm siab nyob rau hauv uas cov hlau hlau hlau hla dhau qhov sib txawv (ntau yam duab) ntawm ib khub rotating rollers, thiab cov khoom hla ntu raug txo thiab qhov ntev yog nce vim qhov compression ntawm cov chais. Kev kos duab hlau: Nws yog ib txoj hauv kev uas rub cov hlau dov hlau (profile, raj, khoom, thiab lwm yam) los ntawm qhov tuag qhov kom txo tau qhov kev sib tshuam thiab ua kom ntev. Nws feem ntau yog siv rau kev ua haujlwm txias.

Cov kav hlau loj-ntev yog tsuas yog ua tiav los ntawm kev txo qis thiab txuas ntxiv dov ntawm cov khoom siv hauv qab hollow yam tsis muaj mandrels. Nyob rau hauv lub premise ntawm kom ntseeg tau cov kauv steel yeeb nkab, kauv steel yeeb nkab yog rhuab mus rau ib tug kub siab tshaj 950 ℃ tag nrho thiab ces dov rau hauv seamless steel kav ntawm ntau yam specifications los ntawm ib tug nro txo ​​zeb. Cov ntaub ntawv txheej txheem rau kev tsim cov kav hlau loj loj qhia tau hais tias kev sib txawv tau tso cai hauv kev tsim cov kav hlau loj: Ntev tso cai sib txawv: Qhov ntev tso cai sib txawv ntawm cov hlau bar thaum nws tau xa hauv qhov ntev yuav tsum tsis pub tshaj + 50 hli. Curvature thiab xaus: Kev khoov deformation ntawm cov hlau ncaj nraim yuav tsum tsis txhob cuam tshuam rau kev siv ib txwm, thiab tag nrho cov curvature yuav tsum tsis pub tshaj 40% ntawm tag nrho qhov ntev ntawm steel bar; qhov kawg ntawm cov hlau tuav yuav tsum tau sheared ncaj, thiab lub zos deformation yuav tsum tsis txhob cuam tshuam rau kev siv. Length: steel tuav feem ntau yog xa mus rau qhov ntev, thiab qhov tshwj xeeb xa khoom ntev yuav tsum tau qhia hauv daim ntawv cog lus; Thaum cov hlau tuav tau xa hauv cov coils, txhua lub kauj yuav tsum yog steel bar, thiab 5% ntawm cov coils hauv txhua pawg tau tso cai muaj ob lub steel tuav. Lub coil hnyav thiab coil txoj kab uas hla yog txiav txim los ntawm kev sib tham ntawm cov khoom thiab cov neeg thov.

Loj-inch steel yeeb nkab txoj kev:
1. Cov txheej txheem kub thawb nthuav dav: Cov khoom siv thawb nthuav dav yog qhov yooj yim, tus nqi qis, yooj yim rau kev tswj hwm, kev lag luam, thiab ruaj khov, thiab cov khoom specifications yuav hloov tau yooj yim. Yog tias koj xav tau npaj cov kav hlau loj loj thiab lwm yam khoom zoo sib xws, koj tsuas yog yuav tsum tau ntxiv qee cov khoom siv ntxiv. Nws yog qhov tsim nyog rau kev tsim cov kav dej nruab nrab thiab nyias-walled loj-inch steel kav, thiab tseem tuaj yeem tsim cov kav dej tuab uas tsis pub dhau lub peev xwm ntawm cov khoom siv.
2. Cov txheej txheem kub extrusion: Qhov khoob yuav tsum tau ua ntej extrusion. Thaum extruding kav nrog ib txoj kab uas hla ntawm tsawg dua 100 hli, cov cuab yeej siv peev yog me me, cov khoom pov tseg me me, thiab cov cuab yeej siv tau zoo heev. Txawm li cas los xij, ib zaug ntawm txoj kab uas hla ntawm cov yeeb nkab nce, cov txheej txheem kub extrusion yuav tsum muaj cov khoom loj-tonnage thiab cov khoom siv hluav taws xob siab, thiab cov kev tswj hwm yuav tsum tau hloov kho dua tshiab.
3. Kub tho txoj kev dov: Kub tho qhov dov yog feem ntau longitudinal dov extension thiab oblique dov extension. Longitudinal extension dov feem ntau suav nrog txwv mandrel nruam dov, txwv mandrel nruam dov, peb-cov menyuam txwv mandrel txuas ntxiv dov, thiab ntab mandrel txuas ntxiv dov. Cov txheej txheem no muaj kev ua haujlwm siab, kev siv hlau tsawg, cov khoom zoo, thiab kev tswj xyuas, thiab tau siv dav zuj zus.

Tsim nyog parameter rau flaw nrhiav tau ntawm loj-inch steel kav:
Hauv kev tsim cov kav hlau loj, ib qho kev sib koom ua ke thiab qhov pores nrog lub vuam txoj kab uas hla tsis tshaj 3.0mm lossis T / 3 (T yog cov txheej txheem phab ntsa tuab ntawm cov yeeb nkab steel) tsim nyog, qhov twg me dua. Nyob rau hauv ib qho 150mm lossis 12T ntev weld ntau yam (qhov twg me dua), thaum lub sijhawm nruab nrab ntawm ib qho kev suav nrog thiab qhov pore tsawg dua 4T, qhov sib npaug ntawm cov diameters ntawm tag nrho cov teeb meem saum toj no uas tau tso cai kom muaj nyob sib cais yuav tsum tsis pub tshaj 6.0mm. los yog 0.5T (qhov twg me dua). Ib leeg strips suav nrog qhov ntev tsis tshaj 12.0mm lossis T (qhov twg me dua) thiab qhov dav tsis tshaj 1.5mm yog tsim nyog. Nyob rau hauv ib qho 150mm lossis 12T ntev weld (qhov twg me dua), thaum qhov sib txawv ntawm cov neeg suav nrog tsawg dua 4T, qhov ntev tshaj plaws ntawm tag nrho cov teeb meem saum toj no uas tau tso cai muaj nyob sib cais yuav tsum tsis pub tshaj 12.0mm. Ib leeg tom ntug ntawm txhua qhov ntev nrog qhov siab tshaj plaws ntawm 0.4mm yog tsim nyog. Ib leeg tom ntug nrog qhov ntev tshaj plaws ntawm T / 2, qhov siab tshaj plaws ntawm 0.5mm thiab tsis pub tshaj 10% ntawm cov phab ntsa uas tau teev tseg yog tsim nyog tsuav yog tias tsis muaj ntau tshaj ob qhov tom kawg hauv ib qho 300mm weld ntev. Tag nrho cov tom kawg yuav tsum yog hauv av. Txhua qhov tom qab qhov siab tshaj qhov saum toj no yuav tsum tau kho, qhov chaw teeb meem yuav tsum raug txiav tawm, lossis tag nrho cov yeeb nkab steel yuav tsum tsis lees paub. Cov tom ntawm txhua qhov ntev thiab qhov tob uas sib tshooj ntawm tib sab ntawm lub vuam sab hauv thiab sab nrauv weld nyob rau hauv txoj kab ntev yog tsis tsim nyog.
