Dowel pins yog ib qho kev lag luam fastener uas muaj peev xwm koom nrog ob lossis ntau qhov chaw ua ke. Txawm hais tias dowels tej zaum yuav ua los ntawm ntoo, hlau, los yog yas, lawv ib txwm yog luv luv cylindrical rods uas yog tapered, slotted, los yog grooved. Txij li cov dowels feem ntau yog siv los tswj cov kev sib raug zoo ntawm lub tshuab qhov chaw lossis raws li cov lus qhia, nws yog qhov tsim nyog kom muaj kev nkag siab yooj yim ntawm cov hom fasteners thiab ntau hom muaj nyob hauv khw.
Tsis zoo li ntau lwm yam khoom, lub dowel tsis muaj kev tsav tsheb lossis txav mus. Hloov chaw, lawv cia siab rau lawv cov coefficient siab ntawm kev sib txhuam kom nyob twj ywm hauv xovxwm-haum, pre-drilled qhov lawv muab tso rau hauv, thiab cov nplaum ntxiv tuaj yeem siv rau kev ruaj ntseg ntxiv. Dowels kuj tuaj yeem tshwm sim hauv lawv cov khoom vim tsis muaj qee yam ntsiab lus, ua rau lawv cov kev daws teeb meem zoo tshaj plaws rau cov rooj tog zaum thiab lwm yam khoom siv zoo nkauj.
Txhawm rau kom ntseeg tau tias tag nrho cov khoom sib dhos nyob ua ke yam tsis tas yuav tsum tau txuas ntxiv, cov dowels xaiv yuav tsum nruj thaum nruab. Rau qhov zoo tshaj plaws haum, lub qhov dowel mus rau hauv yuav tsum yog tib yam loj los yog me ntsis me dua lub dowel. Txij li thaum dowels twb tau tsim kev tawg lub zog uas qhia tias thaum twg ob npaug shear tau tshwm sim, nws yog ib qho tseem ceeb los txheeb xyuas cov peev txheej ua haujlwm ua ntej txiav txim siab yuav khoom.
Thaum tsim cov dowels, cov txheej txheem yuav txawv nyob ntawm seb cov khoom siv thiab kev tsim ntawm lub fastener koom nrog. Piv txwv li, ntoo dowels tuaj yeem tsim tau siv tib lub dov mills raws li lwm yam khoom siv cylindrical thiab ntoo, tsuas yog me dua hauv cov qauv thiab qhov loj me. Feem ntau cov ntoo dowels yog ua los ntawm cov ntoo tawv thiab tuaj yeem npaj los yog grooved raws li qhov xav tau.
Rau cov hlau dowels, cov txheej txheem melting thiab casting yog ua raws li cov txheej txheem txheej txheem, uas pib los ntawm melting thiab refining ntawm raw cov ntaub ntawv thiab xaus nrog ntau yam kev kuaj xyuas zoo. Nyob ntawm daim ntawv thov, muaj ntau yam khoom siv, nrog rau kev xaiv xws li txhuas, tooj dag, stainless hlau, hlau, thiab titanium. Raws li cov khoom siv kawg, cov pins yas feem ntau yog tsim los ntawm cov yas txhaj tshuaj molding.
Ntxiv nrog rau kev txiav txim siab cov khoom siv twg yog qhov zoo tshaj plaws, koj yuav tsum siv sijhawm los txiav txim siab cov hlau lead loj nyob rau hauv cov nqe lus ntawm sab nraud thiab qhov ntev. Rau sab nraud txoj kab uas hla, tib neeg tab tom tham txog kev ntsuas ntawm ntug uas txiav txim siab qhov dav. Lub caij no, qhov ntev yog qhov ntsuas tau ua rau ntawm qhov ntev tshaj plaws ntawm cov khoom siv.
