Dowel pins tau siv dav rau kev sib tw, tab sis kuj tseem tuaj yeem ua haujlwm zoo li cov kabmob nto rau kev sib hloov. Lwm qhov txiaj ntsig yog lawv tuaj yeem raug tshem tawm thiab hloov los ntawm cov neeg siv kawg yam tsis muaj kev cuam tshuam.
Wenqi Machinery tau ua dowel pins txij li xyoo 2000, thiab rab koob yob txij li xyoo 1995.
Groove thiab dowel pins yog tab sis ob ntawm ntau tus neeg tsim khoom siv los sib sau ua ke ntau yam xws li lub cav tsheb, compressor pistons thiab pleev hmoov compacts. Qhov tseem ceeb sib npaug rau cov tuam ntxhab yog cov hlau dowels, uas ua kom muaj kev sib raug zoo ntawm cov khoom sib txuas nrog qhov tsawg kawg nkaus npaj.
Ob lub pins thiab dowels yog tus nqi-zoo, nruab tau yooj yim thiab muaj cov ntaub ntawv ntev xyoo ntawm kev ua tiav. Tsis xav tias lawv tau nrov nrov ntawm cov tuam txhab lag luam hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog tsheb, khoom siv kho mob thiab kev ua si.
Ntau hom pins yog siv los ua ke, thiab tau muab faib ua cov khoom los yog hollow, nrog rau cov duab sib xws lossis cov duab asymmetric. Khoom symmetric pins muaj xws li dowel, grooved, knurled, barbed thiab ferrol. Flat- thiab round-headed versions ntawm cov pins, tseem hu ua studs, yog suav tias yog asymmetric.
Hollow symmetric pins yog slotted thiab coiled caij nplooj ntoos hlav. Tag nrho cov dowels yog hollow symmetrical nrog ib tug sib cais los yog seamless lub cev.
Pins thiab dowels ntsuas los ntawm 0.03125 mus rau 1.5 nti inch thiab mus txog 6 ntiv tes ntev. Lawv feem ntau yog ua los ntawm cov pa roj carbon tsawg lossis stainless hlau, ntau yam alloys, txhuas, tooj dag lossis titanium. Cov khoom tiav suav nrog passivated, nonpassivated thiab dub oxide.
Lub dowel tus pin yog lub tog raj kheej du ntawm cov hlau, txawm hais tias nws tuaj yeem raug chamfered ntawm txhua qhov kawg los pab kev nkag. Tus pin no feem ntau hardened thiab tsim kom meej fractional diameters thiab ntev, thiab siv los ua pob khawm, ncej lossis pivot los nrhiav lossis tuav cov khoom ua ke.
Tus pin dowel withstands lub zog shear tshaj plaws ntawm txhua tus pin fastening. Nws yog qhov zoo dua rau kev sib dhos ua haujlwm siab vim nws yuav tsum tsis muaj cov khoom siv txuas ntxiv rau kev ntxig lossis kev ua haujlwm thib ob.
Cov grooves ntawm tus pin grooved yog tsim los ntawm kev ua haujlwm swaging uas peb cov cuab yeej nkag mus rau lub nominal txoj kab uas hla ntawm tus pin hlau ntawm 120-degree intervals. Qhov kev nkag mus no txav ib qho kev tswj hwm ntawm cov hlau mus rau txhua sab ntawm cov cuab yeej grooving, tsim ib feem ntawm ib sab ntawm txhua qhov zawj.
Hom pin no yog qhov zoo rau cov pob qij txha mus tas li lossis cov uas xav tau kev sib hloov lossis kev sib hloov, nrog rau qhov chaw nyob. Ntau lub tuam txhab nyiam siv zawj pins rau cov ntsia hlau hauv cov rooj sib txoos uas tsis tu ncua raug kev co siab.
Knurled pins muaj nyob nrog ncaj, helical lossis pob zeb diamond-configured knurls. Tsis zoo li tus pin ncaj dowel, qhov kev tuav pov hwm yog muab los ntawm kev cuam tshuam ntawm tus pin thiab lub qhov, knurled pins yog tsim los txiav rau hauv tus tswv tsev. Txawm li cas los xij, tsis yog knurled los yog grooved pins yuav tsum tau nruj tolerances xav tau los ntawm precision khoom dowel pins.
