Thaum nws los txog kev kho dua tshiab hauv chav tsev lossis tsev, 90% ntawm lub sijhawm koj yuav tsum tau tho qhov. Feem ntau nyob rau hauv ib puag ncig hauv tsev muaj cov welds, cov kav dej lossis cov khoom siv hlau tawv tawv uas yuav tsum tau drilled. Txhawm rau ua cov txheej txheem zoo, koj yuav tsum muaj cov cuab yeej tsim nyog nrog koj. Thiab rau cov xwm txheej zoo li no, cob alt xyaum siv hlau yuav tuaj yeem ua ke. Kev tshuaj xyuas txog cov cuab yeej no yeej ib txwm zoo thiab hais lus rau lawv tus kheej. Tshwj xeeb, peb tuaj yeem hais tias cov no muaj zog, hnav-tiv taus, kub-tiv taus thiab txhim khu kev qha cov cuab yeej uas yuav pab tau tus tswv ntawm lub tsev kom tiv thaiv cov teeb meem ntawm ib feeb thiab ua kom tiav kev kho sai dua.
Dab tsi yog cov xyaum thiab cov khoom siv dab tsi yog ua los ntawm
Cob alt xyaum yog cov cuab yeej txiav hlau uas siv los ua haujlwm nrog cov hlau muaj zog thiab cov hlau uas muaj qib siab tawv. Tab sis kuj xws li cov cuab yeej drilling muab qhov ruaj khov thiab siab qhov tseeb, uas ua rau yooj yim dua ntxivua haujlwm nrog lawv.
Lawv yog tsim los ntawm kev kub ceev steel nrog ntxiv ntawm cob alt. Qhov nrov tshaj plaws cob alt laum rau hlau yog R6M5K5, R9K10, VK6 thiab VK8.
Nyob ntawm tus lej tom qab tsab ntawv xaiv ntawm cob alt, koj tuaj yeem paub seb qhov feem pua ntawm cov hlau tawv no muaj nyob hauv cov cuab yeej. Piv txwv li, nws cov ntsiab lus nyob rau hauv high-ceev cuab yeej steel R9K10 mus txog yuav luag 10%. Raws li, muaj tsawg cob alt nyob rau hauv muaj pes tsawg leeg ntawm R6M5K5 thiab VK6.
Daim ntawv thov teb rau cob alt drilling cuab yeej
Thaum koj xav tau laum ntau qhov hauv cov ntaub ntawv nplaum lossis cov alloys nyuaj xws li tooj liab lossis stainless hlau, cob alt hlau xyaum yog qhov zoo rau qhov no. Kev xyaum qhia tau hais tias cov cuab yeej no haum rau txoj haujlwm:
- nrog cua sov thiab acid resistant steels;
- nrog cov pwm steel;
- nrog corrosion-resistant hlau;
- nrog alloys.
Ntxiv rau, cob alt hlau xyaum tuaj yeem siv tau tsis yog hauv tsev xwb, tab sis kuj tseem nyob hauv kev lag luam rau drilling cam khwb cia hlau, nrog rau kom sai thiab raug ua qhov hauv lwm cov hlau thiab alloys ntawm cov hlau txiav tshuab.
Qhov zoo ntawm cob alt xyaum
Raws li tau sau tseg ua ntej, qhov zoo ntawm cov cuab yeej no yog kev hnav tsis kam thiab kub ua haujlwm. Hauv lwm lo lus, kev xyaum cob alt yuav kav ntev dua hauv lub neej txhua hnub, vim tias lawv tsis tshua muaj kev cuam tshuam.mechanical puas tsuaj thiab tuav kom zoo thaum kub melting kub.
Ntxiv rau, qhov zoo thiab cov yam ntxwv ntawm cov cuab yeej drilling no suav nrog:
- Lub kaum ntse ntse loj (kwv yees li 135 °) uas yog qhov zoo rau kev sib tsoo puag ncig thiab du nto.
- Tsim tshwj xeeb uas tso cai rau qhov raug thiab raug drilling ntawm qhov loj yam tsis muaj cuab yeej ntxiv.
- Zaj nplawm rau kev khiav ceev ceev.
- Txhim kho lub shank, uas txo qhov muaj peev xwm ntawm kev tawg, thiab yog li ua rau kev pabcuam lub neej.
- Lub xub ntiag ntawm cob alt nyob rau hauv cov khoom muaj pes tsawg leeg, uas tso cai rau koj los laum cov hlau tawv xws li txhuas, txhuas, tooj liab lossis tin.
Txoj kev siv cob alt xyaum
Ua ntej koj tho lub qhov, koj yuav tsum xav txog:
- Qhov zoo ntawm cov hlau yuav tsum tau laum. Raws li twb paub lawm, cob alt xyaum yog pom zoo tsuas yog rau high-strength alloy steels thiab alloys nrog high degree ntawm toughness. Hauv lwm qhov xwm txheej, koj yuav tsum xaiv lwm lub cuab yeej.
- Qhov taub. Nyob ntawm qhov xav tau qhov loj me, nws yog qhov tsim nyog yuav tsum tau yuav cov khoom siv cob alt hlau zoo tshaj plaws. Piv txwv li, txhawm rau tho lub qhov nrog txoj kab uas hla ntawm 9 hli, koj yuav tsum tau yuav ib lub laum nrog txoj kab uas hla ntawm 8.6 hli lossis 8.4 hli, vim tias vim qhov cuam tshuam ntawm lub cuab yeej, lub qhov yuav tsum tau ua.nce.
- Qhov tob ntawm qhov xav tau. Yog hais tias, piv txwv li, nws yuav tsum tau drilled nyob rau hauv lub dowel, ces koj yuav tsum tau muab piv rau nws ntev nrog qhov loj ntawm lub laum thiab xaiv ib lub cuab tam 2-3 hli loj.
- Cov cuab yeej siv rau kev drilling, xws li lub tshuab tig rauj lossis laum. Nws tsim nyog nco ntsoov tias ob lub cuab yeej no yog qhov sib txawv. Piv txwv li, xyaum shanks yuav txawv rau ib tug rauj xyaum thiab xyaum xyaum. Thiab thaum kawg, rauj laum yog ntau dua rau chiselling, thaum lub laum tsuas yog haum rau drilling.
- Qhov chaw yuav tsum tau ua. Lub cob alt laum yog qhov zoo rau cov hlau puag ncig lossis du, tab sis tsis zoo li yuav ua tau zoo rau ntawm qhov chaw tiaj tus nrog cov qib siab ntawm roughness.
Drilling Features
Txhawm rau txuas lub neej ntawm txhua lub cuab yeej, suav nrog kev xyaum, koj yuav tsum ua raws qee cov cai. Piv txwv li, nws tsis pom zoo kom siv cob alt xyaum ntawm kev kub ceev, tshwj xeeb tshaj yog thaum tshem cov chips los ntawm lub qhov. Qhov no yuav pab tiv thaiv jamming thiab lub cuab yeej tawg.
Yog tias cov txheej txheem drilling ntev, nws yog qhov tsim nyog los tiv thaiv lub cuab yeej los ntawm kev kub dhau. Ua li no, nws raug nquahu kom dej nws nrog oleic acid lossis so luv luv.
