Thaum sib sau ua ke cov tshuab hnyav, cov txheej txheem steel ua haujlwm, cov khoom siv tuav lossis cov khoom siv hauv tsev, kev ntseeg siab ntawm koj cov fasteners ncaj qha txiav txim siab cov cuab yeej kev nyab xeeb, kev pab cuam lub neej thiab cov nqi tu. Cov khoom lag luam txheem txheem ua haujlwm zoo rau lub teeb- lub luag haujlwm sib dhos, tab sis lawv muaj kev pheej hmoo ncab, shearing lossis loosening nyob rau hauv cov khoom hnyav hnyav thiab kev co tsis tu ncua. Rau cov kws tshaj lij, pab pawg muag khoom thiab cov thawj coj hauv chaw, ib lo lus nug tseem ceeb ib txwm sawv tawm:Dab tsi yog qhov zoo tshaj plaws screws los tuav hnyav hnyav hauv kev lag luam ua haujlwm?
Cov lus teb luv luv yog tias siab -lub zog hnyav hnyav, tsim los rau cov qauv thoob ntiaj teb nruj xws li SAE J429 Qib 8, ASTM A325 thiab ISO 898-}1 Chav Kawm 10.9/12.9, xa lub zog tensile, shear resistance thiab qaug zog durability xav tau rau hnyav-load daim ntaub ntawv. Qhov zoo tshaj plaws ntsia hlau hom sib txawv los ntawm kev teeb tsa kev teeb tsa, kev taw qhia kev thauj khoom thiab ib puag ncig kev ua haujlwm, tab sis tag nrho cov saum toj kawg nkaus - ua haujlwm hnyav-load fasteners qhia cov ntsiab lus tseem ceeb: cov khoom siv hluav taws xob kub-kho alloy steel siv, cov xov xov txuas ntxiv thiab cov ntawv pov thawj lub zog.
Xaiv qhov hnyav -load screws yog ib qho tseem ceeb xws li xaiv cov khoom siv hlau zoo rau koj cov khoom. Founded hauv 2008 ua ib tsev neeg- muaj kev lag luam,Joyear Hlau ua haujlwmyog lub chaw tsim khoom lag luam thoob ntiaj teb tshwj xeeb hauv kev tsim cov ntawv hlau, tooj liab alloy precision stamping thiab hnyav- lub luag haujlwm forklift accessories. Nrog ntau tshaj 15 xyoo ntawm kev lag luam kev lag luam, 5, 000+ square- meter chaw tsim khoom thiab ntau tshaj 300 tus neeg ua haujlwm txawj, peb pab ntau tshaj 100 lub sij hawm ntev - cov neeg koom tes thoob ntiaj teb.
Tag nrho peb cov khoom ua raws li cov qauv thoob ntiaj teb nruj thiab tuav ISO 9001: 2015 thiab ISO14001: 2004 ntawv pov thawj. Peb tsis tsuas yog xa cov khoom zoo tshaj plaws hlau xwb tab sis kuj qhia meej qhov sib txuam hnyav -cov dej num fastening daws rau txhua kab khoom. Tshawb nrhiav peb cov khoom lag luam hlau uas muaj ntau yam ntawmhttps://www.joyearmetalwork.com/. Cov lus qhia dav dav no suav cov ntsia hlau zoo tshaj plaws rau qhov hnyav hnyav, rhuav tshem lawv cov qib zog thiab cov khoom siv, thiab piav qhia seb lawv koom nrog peb cov khoom lag luam li cas.
1. Sab saum toj 5 Qhov Zoo Tshaj Screws rau Tuav Hnyav
Heavy load screws yog categorized los ntawm lub taub hau style, tsav hom thiab load peev xwm. Hauv qab no yog tsib hom kev ntseeg siab tshaj plaws thiab siv dav, qeb los ntawm kev muaj peev xwm thauj khoom thiab kev siv khoom siv:
1.1 Heavy Hex taub hau Bolts (SAE Qib 8 / ASTM A490)
Hnyav hex taub hau bolts yog universally lees paub tias yog qhov zoo tshaj plaws txhua yam -nyob ib ncig ntawm cov ntsia hlau rau cov khoom siv hnyav hnyav. Featuring ib qho loj, tuab - phab ntsa hexagonal lub taub hau thiab tag nrho los yog ib nrab threaded shank, lawv faib clamping quab yuam nyob rau hauv ib tug dav cheeb tsam tiv thaiv lub taub hau rub- los ntawm thiab xov stripping nyob rau hauv hnyav loads.
SAE Qib 8 hnyav hex bolts, ua los ntawm quenched thiab tempered alloy steel, xa ib yam tsawg kawg nkaus tensile zog ntawm 150 ksi (kwv yees li 1034 MPa) thiab yog lub siab tshaj plaws lub zog txheem qib rau kev lag luam siv. Rau kev sib txuas ntawm cov qauv hlau tseem ceeb, ASTM A490 hnyav hex bolts muaj peev xwm ntau dua thiab tau teev tseg rau kev tsim kho choj, crane qauv thiab cov khoom siv hnyav. Lawv sab nraud hex tsav tso cai rau siab torque daim ntawv thov nrog tus qauv wrenches, ua rau lawv yooj yim rau nruab thiab tshuaj xyuas ntawm qhov chaw.
1.2 Alloy Steel Socket Head Cap Screws
Rau cov khoom hnyav sib dhos hauv cov chaw kaw qhov chaw uas siv cov ciaj ntswj sab nraud yog txwv, alloy steel qhov (socket) lub taub hau hau screws yog qhov kev xaiv sab saum toj. Lawv muaj lub taub hau cylindrical nrog rau sab hauv hexagonal tsav, tso cai rau kev teeb tsa nrog Allen wrenches nyob rau hauv nruj recesses thiab nqaim khoob.
Qib 8 lub qhov (socket head cap screws) phim lub zog tensile ntawm hnyav hex bolts nyob rau hauv ib tug ntau compact daim ntawv. Lawv yog cov nyiam fastener rau industrial tshuab cuab yeej sib dhos, automation khoom thiabprecision ntawv hlauenclosures qhov twg tsawg -profile, dej lub taub hau yuav tsum tau. Lawv cov kev ntxhov siab tsis sib xws ntawm lub taub hau -shank hlws ris txo qhov qaug zog tsis ua haujlwm raws li kev rov ua haujlwm tsis zoo.
1.3 Flange Bolts (Anti-Vibration Heavy Duty)
Flange bolts integrate ib tug dav, ncig flange nyob rau hauv lub taub hau uas ua hauj lwm raws li ib tug integrated washer. Qhov kev tsim no nthuav dav clamping quab yuam hla thaj tsam loj dua thiab tiv taus tus kheej -looing tshwm sim los ntawm kev co tsis tu ncua thiab cuam tshuam.
Rau cov khoom siv tuav, kev tsim kho tshuab thiab cov khoom siv hluav taws xob hauv tsheb uas ua haujlwm nyob rau hauv qhov kev vibration tas li, flange bolts outperform standard hex bolts khub nrog cais washers. Ib qho -cov qauv tsim tshem tawm cov tshuab ntxhua khaub ncaws tsis zoo thiab txo lub sijhawm sib dhos. SAE Qib 8 flange bolts muaj txiaj ntsig tshwj xeeb rau cov ntawv thov hnyav uas xoob yuav ua rau muaj kev poob qis lossis kev nyab xeeb.
1.4 Tus qauv Hex Bolts (ASTM A325)
ASTM A325 structural bolts yog cov qauv kev lag luam rau kev tsim kho cov hlau hnyav thiab cov tshuab ua haujlwm hnyav. Ua los ntawm cov pa roj carbon nruab nrab thiab cov cua sov kho kom ua tiav lub zog tensile siab, lawv tau tsim tshwj xeeb rau kev sib txhuam- hom kev sib txuas ntawm cov khoom siv shear yog qhov kev txhawj xeeb tseem ceeb.
Muaj nyob rau hauv ob hom 1 (carbon steel) thiab hom 3 (weathering steel) variants, A325 bolts yog dav siv rau lub Hoobkas steel tsev, cov khoom hnyav thav ntawv thiab cov khoom siv tuav cov tshuab. Lawv tau nruab nrog calibrated torque wrenches kom ua tau raws li preload, kom ntseeg tau tias muaj zog clamping zoo ib yam rau ntev - lub sij hawm kev ntseeg siab.
1.5 Heavy Duty Carriage Bolts
Rausheet hlau fabrication, sab nraum zoov kho vajtse thiab ntoo -hlau hybrid structural kev sib txuas, hnyav lub luag hauj lwm carriage bolts xa zoo heev hnyav-load tuav lub hwj chim nrog ib tug huv si, nyab xeeb tiav tsos. Lawv muaj lub taub hau domed thiab lub xub pwg nyom hauv qab lub taub hau uas xauv rau hauv lub qhov mounting, tiv thaiv cov ntsia hlau los ntawm kev sib tw raws li cov txiv ntoo tau nruj.
Qib 5 thiab Qib 8 hnyav nqa bolts yog qhov zoo tagnrho rau kev txhim kho cov pob khawm loj, cov khoom siv hauv tsev thiab cov txheej txheem hlau vaj huam sib luag. Lawv lub taub hau puag ncig lub taub hau tshem tawm cov npoo ntse kom txhim kho kev nyab xeeb, thiab tus kheej - xauv lub caj dab square ua kom yooj yim rau ib qho - sab kev teeb tsa hauv qhov nyuaj - mus rau - mus txog qhov chaw.
2. Cov Qib Muaj Zog: Yuav ua li cas txheeb xyuas qhov muaj peev xwm hnyav
Tsis yog txhua tus screws sau tias "hnyav luag hauj lwm" xa cov kev ua tau zoo sib npaug. Cov qhab nia qib muaj zog ntawm lub taub hau ntsia hlau yog qhov qhia tau zoo tshaj plaws ntawm qhov muaj peev xwm thauj khoom. Peb feem ntau siv grading systems yog:
