positioning tus pin
Zoo siab txais tos rov qab rau peb "Dab Tsi Heck" series, uas peb tham txog qee qhov tshwj xeeb fasteners thiab cov khoom siv hluav taws xob uas cov tuam txhab siv thaum tsim thiab sib sau ua ke lawv cov khoom. Niaj hnub no, peb yuav qhia koj rau dowel pins.
Tus pin positioning yog dab tsi?
Yog tias koj puas tau mus yuav khoom ntawm IKEA lossis cov rooj tog zaum sib dhos koj tus kheej, koj paub txog cov ntsia hlau zoo li cov ntoo dowels, tseem hu ua dowels, siv los txuas cov khoom ua ke.
Rau kev tsim khoom, dowels yog cov khoom, tsis muaj taub hau, cylindrical ncaj hlau pins nrog lub hauv paus tsis tiav. Feem ntau hardened thiab manufactured kom meej fractional diameters thiab ntev, dowel pins tuaj nyob rau hauv ntau qhov ntau thiab tsawg, style, designs thiab cov ntaub ntawv uas yuav ua rau tsis meej pem ntawm buyers, engineers thiab kawg cov neeg siv! Niaj hnub no, peb mam li sim ua kom yooj yim rau pawg tsis meej pem ntawm fasteners.
Leej twg siv Dowels?
Dowels yog siv los ua hinges, shafts los yog pivots los nrhiav lossis tuav cov khoom ua ke hauv kev sib dhos los yog cov khoom sib dhos.
Lawv yog siv nyob rau hauv ntau yam kev siv nyob rau hauv ntau industries xws li: aerospace, hluav taws xob motors, hydraulic khoom, instrumentation, cuab yeej thiab fixtures, machinery, tub rog, thiab ntau yam ntxiv.
Dowels yog nrov nyob rau hauv cov rooj sib txoos vim hais tias lawv tuaj yeem tiv taus kev ntxig thiab tshem tawm yam tsis muaj deformation. Thiab ntau lawm nyiam pins vim tias lawv yuav tsum tsis muaj cov cuab yeej txuas ntxiv kom ntxig, tsis muaj kev ua haujlwm thib ob, thiab tsis muaj cov khoom sib txuas. Nws tag nrho ntxiv los ua kom ntau lawm thiab ua kom txhua tus hauv cov khoom noj khoom haus zoo siab!
Kuv yuav tsum xav txog dab tsi thaum xaiv tus pin nrhiav?
Txawm hais tias dowel pins muaj nyob rau hauv ntau yam khoom siv thiab cov qauv, muaj ob peb qhov teeb meem loj los xav txog thaum nws los txog rau cov khoom lag luam loj thiab mil-spec.
Txheem, loj lossis me me?
Standard series dowels yog siv rau thawj daim ntawv thov. Lawv lub hauv paus txoj kab uas hla yog {{0}}.0002 ntiv siab siab tshaj qhov nominal txoj kab uas hla. Piv txwv li, ¼ gauge tus pin muaj txoj kab uas hla ntawm 0.2501-0.2503.
Oversized series dowels feem ntau yog siv los ua kom haum rau hauv qhov hnav thiab feem ntau siv tom qab kev lag luam rau kev kho. Lawv lub hauv paus txoj kab uas hla yog {{0}}.001" siab tshaj lub nominal txoj kab uas hla. Piv txwv li, ib tug ¼ oversized dowel muaj ib txoj kab uas hla ntawm 0.2509-0.2511.
Undersized series dowels yog siv rau qhov tsis sib xws. Lawv lub hauv paus txoj kab uas hla yog {{0}}.0002 nti hauv qab nominal txoj kab uas hla. Piv txwv li, ib tug undersized ¼ tus pin muaj ib txoj kab uas hla ntawm 0.2500-0.2498. Mil-P-21143/2- poob rau hauv qeb undersized.
Xaus chamfer lossis radius?
Feem ntau, cov pins coj mus muag yog tsim raws li tus qauv ANSI ASME B18.8.2. Standard alloy pins muaj ib lub vojvoog ntawm ib kawg thiab ib tug chamfer rau lwm yam. Txawm li cas los xij, stainless hlau dowels feem ntau yog tsim nrog chamfers ntawm ob qhov kawg.
Kev lag luam lossis tub rog?
Yog tias koj lossis koj cov neeg siv khoom xav tau DFAR pins hauv tsev kom ua tau raws li cov qauv nruj tshaj plaws, cov tub rog pins yuav yog qhov kev xaiv zoo tshaj rau koj!
Alloy lossis Stainless Hlau? Qhov twg stainless hlau?
Alloy steel yog tus pin muaj zog tshaj plaws thiab yog hardened. Nws tuaj yeem ua tiav nrog cov oxide dub los muab cov xeb zoo dua li cov alloys.
Hom 416 stainless hlau yog cov khoom siv zoo tshaj plaws stainless hlau thiab yog cov khoom siv hauv MS16555 thiab MS16556 series. Sib nqus.
Hom 18-8/303 stainless hlau yog feem ntau siv stainless hlau thiab yog cov khoom txheem rau Mil-P-21143 series.
Hom 316 stainless hlau yog feem ntau corrosion resistant stainless hlau muaj thiab tsis txuam nrog mil-spec qhov chaw.
Puas muaj lwm yam los xav txog?
Dowels feem ntau pom nyob rau hauv lawv tus lej mil-spec, uas tuaj yeem hla nrog kev lag luam sib npaug. Qee hom Mil-Spec series rau dowel pins suav nrog Mil-P-21143 (303 stainless hlau), MS16555 (alloy thiab 416 stainless hlau muaj nyob rau hauv tus qauv series), thiab MS16556 (alloy thiab 416 stainless hlau muaj nyob rau hauv lub oversized. series).
Yog tias koj tsis xaj los ntawm MS lossis NAS mil-spec tus lej, Inch alignment pins ua raws li ANSI/ASME B18.8.2. Rau kev lag luam pins, thov saib xyuas kom qhia meej cov khoom xav tau thiab qhov ntev ntev. Tshwj tsis yog hais tias lwm yam, dowel pins yog precision av, hardened thiab cua sov kho kom haum Rockwell hardness.
Nco ntsoov, tsis txhob siv rauj! Thaum txhim kho dowels, tsis txhob yuam tus pin rau hauv lub qhov, ib txwm nias rau hauv kom tau txais txiaj ntsig zoo tshaj plaws.
