Bolts yog ib qho ntawm feem ntau cov fasteners hauv cov khoom siv kho tshuab. Qhov tseeb thiab kev ntseeg tau ntawm lawv txoj kev sib txuas ncaj qha cuam tshuam rau kev nyab xeeb thiab kev pabcuam lub neej. Txawm hais tias sib sau ua ke yooj yim cov rooj tog lossis tsim cov khoom siv lag luam, kev sib tw pob tw xaiv, kev teeb tsa, thiab txij nkawm yog qhov tseem ceeb heev. Kab lus no yuav tham txog cov ntsiab lus tseem ceeb ntawm cov kev sib txuas lus sib txuas los pab cov nyeem kom nkag siab txog qhov no tseem ceeb txheej txheem.
I. BALT LOM HOM HOM THIAB XAIV
Bolts tuaj nyob rau ntau yam. Lawv tuaj yeem raug categorized los ntawm lub taub hau zoo, xws li hexagonal, hexagon ntsaws, ncig, thiab hau xwm fab; Los ntawm xov hom, lawv tuaj yeem raug cais ua cov ntxhib, zoo, thiab cov xov tshwj xeeb; Thiab los ntawm cov khoom siv, lawv tuaj yeem faib rau cov hlau carbon, hlau steel, hlau stainless, thiab almloy steel. Cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv Bolts:
Cov kev yuav tsum tau: thaum yuav ua rau muaj kev nce qib (xws li kev co), nplua {{} {Lauj Alloy Bolts yog nyiam. Rau cov khoom siv zoo li qub, cov ntxhia ntxaib {}}} xov bolts yuav siv tau.
Kev hloov kho ib puag ncig: stainless hlau (xws li 304/316) lossis galvanized bolts yog qhov yuav tsum tau muaj nyob rau hauv ib puag ncig vaum lossis corrosive ib puag ncig. Thaum tshav kub kub - Cov ntaub ntawv resistant (xws li 12.9 qib aliro alloy) yog qhov yuav tsum tau rau siab- qhov kev thov kub.
Precision Maticing: Hexagon qhov kev pom zoo bolts kom tsis txhob muaj kev puas tsuaj sab nraud thiab kev sib tsoo, lub sijhawm hexagonal lub taub hau siv rau cov cuab yeej loj los pab txhawb cov cuab yeej.
Ii. Cov txheej txheem txheej txheem kev teeb tsa rau BOLTED kev sib txuas
Cov txheej txheem daws teeb meem yog qhov tseem ceeb rau kev ua kom muaj kev sib txuas tau zoo. Cov txheej txheem raug suav nrog:
Pretreatment: ntxuav cov chaw ntawm cov seem (tshem tawm cov roj (tshem tawm cov roj, av, thiab burrs). Yog tias tsim nyog, siv xov xov tooj sib txuas lossis cov tshuab ntxhua khaub ncaws (xws li lub caij nplooj ntoo hlav lossis cov hniav ntxuav hniav).
Pre - tighting: Siv lub torque wrench kom nruj nyob rau hauv cov kauj ruam siv tus qauv "(tshwj xeeb yog rau ntau- ntsia liaj qhov loj). Pib zawm txog 50% -70% ntawm cov kev pom zoo kom pom zoo. Qhov kawg torque yuav tsum nruj ua raws li tus qauv txheem (piv txwv li, tus kheej lub zog rau M10 Bolt yog 40-60 n· m).
Anti {-} loosening ntsuas: ntxiv rau cov tshuab ntxhua khaub ncaws, xov xwm tshiab (xws li punch ntsiab lus (stamping thiab deforming cov xov xaus) kuj tseem siv tau.
III. Cov qauv tsis ua haujlwm thiab cov kev daws teeb meem
Bolt kev sib ntsib tsis ua haujlwm feem ntau manifest li loosening, tawg, lossis xov stripping. Cov ua thiab countermeasures muaj raws li nram no:
Loosening: kev co kom muaj kev sib txhuam. Qhov no tuaj yeem hais los ntawm kev ntxiv cov cuab yeej xauv (xws li cov nylon ntxig txiv ntseej) lossis los ntawm kev kuaj kom pom tseeb.
Breakage: Ntau dhau los yog khoom tsis xws luag tuaj yeem ua rau qhov no. Kos rau lub zog ntsia liaj qhov rooj deb (piv txwv li, 8.8-qib bolts muaj lub zog tensile ntau dua lossis sib npaug nrog 800 mpa) thiab zam kev ua haujlwm tom qab.
Xov stripping: xov hnav lossis ntau zog quab yuam thaum nruab. Nws raug nquahu kom siv cov bolts loj dua lossis kho cov xov threite (piv txwv li, los ntawm txhim kho cov hlau hlau tom qab tapping).
IV. Cov ntawv thov siab thiab thev naus laus zis thev naus laus zis
Hauv kev lag luam niaj hnub, kev siv tshuab kub yog ALVOLING:
Hydraulic tensioning: pre {- tightening yog tiav los ntawm ncaj qha trank nrog lub ntsuas kev sib txhuam cuam tshuam nrog cov txheej txheem kev sib txhuam. Cov qauv no yog tsim nyog rau siab- precision cov ntawv thov xws li nuclear hwj chim thiab aviation.
Tus Neeg Saib Xyuas Txoj Kev Seem Tshiab lossis RFID CHIPS saib xyuas ua ntej thiab siv rau kev saib xyuas kev noj qab haus huv zoo xws li txuas hniav thiab cua tshuab raj.
Tus kheej - tapping bolts: cov bolts tuaj yeem nkag mus rau cov ntaub ntawv mos (xws li aluminium al ...} drilling, streamlining lub rooj sib txoos.
Tag
Txawm hais tias lawv me me, bolts yog "kev nyab xeeb txuas" ntawm cov tshuab ua tshuab. Los ntawm kev xaiv rau kev saib xyuas, txhua yam tuaj yeem txiav txim siab txog kev ntseeg tau ntawm cov khoom siv tag nrho cov khoom siv. Mastering scalorific part kev twb kev txuas yuav tsum tsis muaj theoretical kev taw qhia tab sis kuj tau siv cov kev paub ua tau zoo. Rau cov engineers, kev soj ntsuam txuas ntxiv mus ntxiv cov ntaub ntawv tshiab thiab cov txheej txheem tseem ceeb rau kev tsim cov kev sib txuas ruaj khov rau cov haujlwm ua haujlwm nyuaj.
