Xaiv txoj cai skiving raj rau lub tog raj kheej hydraulic yog ntau dua li xaiv cov qib hlau tsim nyog thiab lub raj loj.
Lub tog raj kheej lub tog raj kheej yog ib qho tseem ceeb ntawm lub tog raj kheej hydraulic. Nws txoj kab uas hla sab hauv, phab ntsa tuab, cov khoom siv, nto tiav, ncaj, thiab qhov tseeb qhov tseeb tuaj yeem cuam tshuam rau lub tog raj kheej kev ua haujlwm, kev sib khi, kev pabcuam lub neej, thiab kev tsim khoom.
Vim li no, hydraulic lub tog raj kheej cov tuam txhab yuav tsum xaiv lub skived thiab cov menyuam kub hnyiab raj raws li kev ua tiav lub tog raj kheej tsim thiab cov kev qhia tshwj xeeb, tsis yog xaiv lub raj raws li tus nqi lossis qhov loj me.
Phau ntawv qhia no piav qhia txog cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub skiving raj rau hydraulic lub tog raj kheej daim ntaub ntawv.
1. Dab tsi yog Skiving Tube?
Lub raj skiving yog ib lub raj steel precision uas tau raug siv hauv tshuab siv cov txheej txheem skiving.
Hauv ntau daim ntawv thov hydraulic lub tog raj kheej, lub raj yog tsim los ntawm kev sib xyaw ua ke ntawm:
Skiving + Roller Hlawv
Qhov no feem ntau hu ua SRB raj lossis skived thiab cov menyuam kub hnyiab raj.
Thaum lub sij hawm skiving, ib tug precision txiav cuab yeej tshem tawm ib tug tswj tus nqi ntawm cov khoom ntawm sab hauv nto.
Roller burnishing ces siv hardened rollers kom du thiab plastically deform lub sab hauv.
Lub resulting raj tuaj yeem muab tau:
Precise internal txoj kab uas hla
Tsawg sab hauv roughness
Zoo roundness
Zoo ncaj
Ua tib zoo sab hauv qhov zoo
Kev tsim khoom tsim nyog rau kev siv tsim nyog
Cov yam ntxwv no ua rau SRB raj siv dav rau hydraulic lub tog raj kheej chim.
2. Pib nrog cov kev xav tau ntawm lub tog raj kheej Hydraulic
Thawj kauj ruam yog tsis xaiv lub raj.
Thawj kauj ruam yog nkag siab txog lub tog raj kheej.
Cov lus nug tseem ceeb suav nrog:
Lub siab ua haujlwm yog dab tsi?
Qhov siab tshaj plaws yog dab tsi?
Lub tog raj kheej bore yog dab tsi?
Mob stroke yog dab tsi?
Lub piston ceev yog dab tsi?
Hom dej hydraulic siv li cas?
Qhov kev khiav hauj lwm kub yuav tsum yog dab tsi?
Dab tsi yog sealing system yog siv?
Qhov kev pab cuam lub neej yog dab tsi?
Puas yog lub tog raj kheej siv hauv cov qauv lossis hnyav- daim ntawv thov?
Cov kev xav tau no pab txiav txim siab cov khoom siv tube tsim nyog, qhov ntev, phab ntsa thickness, nto tiav, thiab kam rau ua.
Lub raj uas ua haujlwm tau zoo rau qhov qis - lub tog raj kheej muaj zog yuav tsis haum rau lub tshuab ua haujlwm siab -.
3. Xaiv qhov raug sab hauv txoj kab uas hla
Lub taub sab hauv (ID) yog ib qho tseem ceeb tshaj plaws thaum xaiv lub raj skiving.
Tus ID txiav txim siab lub tog raj kheej bore thiab ncaj qha cuam tshuam rau piston qhov ntev.
Piv txwv li, daim duab cylinder tuaj yeem hais qhia:
ID: 100 mm
Tab sis cov ntaub ntawv no tsuas yog ua tsis tiav.
Koj tseem yuav tsum paub qhov xav tau:
ID kam rau ua
Roundness
Nto roughness
Kev ncaj
Daim ID tiav yuav tsum sib haum nrog lub piston, cov ntsaws ruaj ruaj, cov lus qhia cov khoom, thiab lub tog raj kheej tsim.
Vim li cas ID Tolerance Matters
Yog tias tus ID loj dhau lawm, lub piston thiab cov ntsaws ruaj ruaj yuav tsis ua tiav qhov haum.
Yog tias tus ID me dhau lawm, kev sib dhos tuaj yeem nyuaj thiab kev sib txhuam yuav nce ntxiv.
Yog li ntawd, lub raj xa khoom yuav tsum tsim thiab tshuaj xyuas cov kab hauv qab raws li qhov pom zoo specification.
4. Xaiv qhov tsim nyog sab nraud
Sab nraud txoj kab uas hla (OD) txiav txim siab tag nrho qhov loj ntawm lub cylinder chim nrog rau phab ntsa thickness.
Piv txwv li:
ID=100 mm
OD=120 hli
Qhov no muab lub nominal phab ntsa thickness ntawm:
(120 - 100) ÷ 2=10 hli
Txawm li cas los xij, qhov xav tau tiag tiag ntawm phab ntsa thickness yuav tsum tsis txhob xaiv los ntawm qhov ntev ntawm lub raj.
Nws yuav tsum raug soj ntsuam raws li lub tog raj kheej:
Ua hauj lwm siab
Siab siab tshaj plaws

Phab ntsa thickness yog tshwj xeeb tshaj yog ib qho tseem ceeb rau hydraulic thooj voos kheej kheej ua hauj lwm nyob rau hauv siab siab los yog cyclic loading.
Lub raj tuab feem ntau muab cov qauv tsim muaj peev xwm ntau dua, tab sis ua rau phab ntsa tuab kuj nce ntxiv:
Qhov hnyav
Khoom siv
Machining xav tau
Zuag qhia tag nrho lub tog raj kheej loj
Yog li ntawd, lub hom phiaj tsis yog tsuas yog xaiv cov raj tuab tshaj plaws.
Qhov tseeb phab ntsa tuab yuav tsum muab cov qauv tsim nyog thaum ua tau raws li qhov hnyav, tus nqi, thiab qhov xav tau ntawm lub tog raj kheej.
Rau cov ntawv thov tseem ceeb, phab ntsa thickness yuav tsum tau txheeb xyuas los ntawm kev suav cov engineering tsim nyog es tsis yog kwv yees los ntawm cov kev cai dav dav.
6. Xaiv Cov Qib Hlau Zoo
Kev xaiv cov khoom siv yog lwm qhov tseem ceeb.
Cov qib steel feem ntau pom zoo rau hydraulic lub tog raj kheej raj muaj xws li:
E355
