Rolling
Copper qws dov muaj peb hom: qhov dov, spinning dov thiab planetary dov.
1. Lub qhov dov: Ib txoj hauv kev ntawm qhov ntev dov ntau hom ntaub ntawv ntawm ob-yob lossis peb-yob zeb siv lub qhov uas tsim los ntawm cov grooves ntawm cov yob.
2. Spinning rolling: Ib txoj kev pub mis thiab spinning lub rotating hlau disc los yog preformed dawb paug los ntawm ib tug spinning log.
3. Planetary dov: Ib txoj kev dov ntawm extruding ntau yam khoom ntawm ib lub zeb uas muaj ib los yog ob qho kev txhawb nqa yob thiab ntau lub planetary yob nyob ib ncig ntawm cov yob txhawb.
stretching
1. Txhais kev ncab
Stretching yog txoj kev ua haujlwm siab uas dhau qhov khoob ntawm qhov tuag thiab siv qhov nro los hloov nws cov duab thiab qhov loj. Nws kuj yog ib txoj hauv kev tseem ceeb rau kev ua tiav cov tooj liab pas hlau.
2. Cov yam ntxwv ntawm kev ncab
Los ntawm cov txheej txheem no, cov duab thiab qhov loj ntawm cov khoom ua tau raws li qhov yuav tsum tau ua, thiab nws muaj cov yam ntxwv ntawm qhov siab qhov tseeb thiab qhov chaw zoo.
3. Kev faib tawm ntawm cov khoom siv stretching
Common stretching khoom muaj xws li saw stretching tshuab, disc stretching tshuab, hydraulic stretching tshuab thiab ua ke stretching tshuab. Chain stretching tshuab yog tsuas yog siv rau stretching ncaj cov khoom, thiab muaj ib leeg saw, ob chav saw thiab ib kab, multi-line stretching tshuab. Disc stretching tshuab yog tsuas yog siv rau zus tau tej cov me me thiab nruab nrab txoj kab uas hla discs. Ua ke stretching tshuab feem ntau tsim cov khoom me me los ntawm cov discs rau cov khoom ncaj nraim, uas tuaj yeem ua tiav ib txhij txog kev ncab, ncaj, nto polishing, tsau-ntev shearing ntawm cov khoom, thiab ncaj qha tsim cov khoom tiav.
Kev kho cua sov
Kev kho cua sov ntawm lub raj thiab pas nrig hlau yog feem ntau nruab nrab annealing thiab tiav cov khoom annealing. Lub tshuab annealing yog tsim raws li cov yam ntxwv ntawm cov khoom siv, cov khoom lag luam thiab cov kev xav tau ntawm kev ua haujlwm. Tam sim no, kev kho cua sov ntawm lub raj thiab pas nrig hlau siv dav siv lub tswb nrov, cov menyuam hauv qab rauv thiab cov hlua txuas nrog cov cua sov tshwj xeeb. Thaum txais kev tiv thaiv huab cua, kev ncig ntawm huab cua yog ntxiv dag zog kom ntseeg tau tias huab cua zoo ib yam thiab ci ntsa iab ntawm cov khoom.
Nyob rau hauv kev kho cua sov ntawm pas nrig profiles, kuj muaj quenching thiab aging tshav kub kho. Nws yog tsuas yog siv rau kev kho cua sov ntawm cov alloys nrog kev laus zog cov yam ntxwv los txhim kho lub zog thiab kev ua tau zoo ntawm cov ntaub ntawv. Lub quenching ntawm cov khoom extruded feem ntau yog ua tiav los ntawm extrusion qhov hluav taws xob dej foob, thaum kos cov khoom yuav tsum tau tshwj xeeb quenching rauv.
Ua tiav
Kev ua tiav ntawm tooj liab alloy raj, rods thiab cov xov hlau feem ntau suav nrog kev txiav taub hau thiab tails (sizing), straightening, deg kho, thiab lwm yam. thiab shearing. High-precision thiab loj-loj khoom yog feem ntau sawed. Kev ncaj yog qhov tseem ceeb ntawm cov khoom siv raj thiab pas nrig.
Feem ntau siv cov tshuab straightening rau cov raj, cov pas nrig thiab cov profiles muaj xws li cov menyuam ncaj cov cav tov, lub siab ncaj tshuab, sine straightening machines thiab nro straightening machines, thiab cov menyuam straightening tshuab yog cov feem ntau siv. Roller straightening machines yog cov khoom uas ncaj nraim los ntawm kev rov khoov dua los ntawm cov menyuam sib txawv. Lub siab ncaj tshuab feem ntau yog siv rau kev ncaj cov kab loj lossis super-loj tuav, profiles thiab tuab-walled kav. Sine straightening feem ntau yog siv los kho cov kav dej me me thiab tuav los ntawm kev rov khoov los ntawm sine straightening rollers. Tension straightening tshuab clamps ob kawg ntawm cov khoom thiab siv rov qab nro kom cov khoom me ntsis deformed mus cuag lub hom phiaj ntawm straightening. Nws yog tsuas yog siv rau straightening tshwj xeeb profiles, thiab nws elongation ncav cuag 1-3%.
Txhawm rau ua kom lub ntsej muag ntawm cov khoom tiav yog huv si thiab ci, qhov saum npoo ntawm cov khoom yuav tsum tau kho, uas tuaj yeem ua tau phau ntawv lossis tsis siv neeg. Kev kho mob ntawm tes yog feem ntau yog rau tus neeg teb xov tooj los so cov roj stains thiab av ntawm qhov chaw ntawm cov yeeb nkab thiab bar (xws li siv cov cua compressed los ntaus hauv cov yeeb nkab nrog cov paj rwb, thiab lwm yam). Kev kho tsis siv neeg feem ntau yog ntxuav cov yeeb nkab thiab bar hauv cov kua uas muaj cov tshuaj ntxuav (xws li tshuab hauv cov yeeb nkab) thiab ziab.
