Dab tsi yog Elastic Rail Clips ua los ntawm
Elastic rail clips feem ntau yog ua los ntawm lub caij nplooj ntoos hlav steel los ntawm txheej txheem forging. Forged khoom yog tsim los ntawm kub forging, nyob rau hauv qhib tuag los yog kaw tuag. Cov khoom siv tau zoo thaum cov hlau tsim tom qab tau rhuab rau forging kub. Cov khoom ntawm cov khoom forged yog suav hais tias zoo dua li cov khoom ntawm cov khoom tsim los ntawm lwm cov txheej txheem hlau vim yog cov qauv microstructure zoo tshaj plaws. Qhov kev sib txuam no tseem ceeb vim tias qhov clip yuav tsum khoov elastically lab lub sij hawm tsis muaj tawg.
Caij nplooj ntoos hlav Steel Qib siv rau Clips
Tus qauv caij nplooj ntoos hlav steel qib rau rail clips yog 60Si2MnA, 60Si2CrA, 55Si2Mn thiab 38Si7. Cov muaj pes tsawg leeg ntawm 60Si2MnA yog carbon 0.56 txog 0.64 feem pua, manganese 0.60 mus rau 0.90 feem pua, silicon 1.60 rau 2.00 feem pua thiab chromium mus txog 0.35 feem pua. Qib 60Si2CrA muaj chromium ntawm 0.70 mus rau 1.00 feem pua rau kev txhim kho hardenability, 55Si2Mn nqa carbon 0.52 mus rau 0.60 feem pua nrog silicon 1.50 mus rau 2.00 feem pua, thiab 38Si7 nqa carbon 0.35 mus rau 0.500.41 feem pua. Phosphorus thiab sulfur raug txwv rau 0.03 feem pua hauv txhua qib.
Hardness thiab Fatigue Performance
Tom qab kev kho cua sov, E- hom clips ncav cuag hardness ntawm 44 txog 48 HRC thiab screwed nro clamps ncav cuag 42 txog 47 HRC. Lub neej qaug zog nyob ntawm txoj kab uas hla: clips nrog 18 hli hlau tiv taus 3 lab lub voj voog yam tsis muaj kev tawg thiab clips nrog 20 hli hlau tiv taus 5 lab lub voj voog tsis tawg. Qhov kev ua haujlwm qaug zog no yog cov cuab yeej uas ua kom lub zog clamping ruaj khov nyob rau hauv kev pab cuam lub neej ntawm kev khiav thiab tiv thaiv kev tawg ntxov ntxov nyob rau hauv rov qab lub log.
Kev Kho Hniav thiab Cov Qauv
Cov kev xaiv saum npoo muaj xws li cov roj av dawb, oxide dub, xim pleev xim, kub dip galvanizing thiab zinc plating. Cov qauv siv yog DIN 17221, BS 970 thiab GB / T 1222 rau lub caij nplooj ntoos hlav steel thiab cov clips tiav. Nrog kev tswj nruj nruj thiab cov hlau zoo caij nplooj ntoos hlav, elastic rail clips tau khaws cia nyob rau hauv qhov kev teev tseg kom tau raws li cov neeg siv khoom xav tau, muab kev ua haujlwm siab clamping ua ke nrog kev yooj yim ntawm kev teeb tsa.
Main Clip Models thiab Parameters
Lub ntsiab clip muaj xws li hom III clip nrog 18 hli hlau ntawm 0.80 kg, lub E1609 nrog 16 hli hlau ntawm 0.43 kg, lub E1809 ntawm 0.61 kg, lub E1813 ntawm 0.62 kg thiab lub 20 hli series E2001, E2007, E20559, E2, E2001, E2007, E20559, E2. E2063 ntawm 0.80 kg ib thooj, tag nrho hauv 60Si2MnA. Qhov ntau kuj suav nrog cov clip tshwj xeeb xws li 18 mm Russia rail clip ntawm 0.58 kg thiab 20 mm anti{24}}vandal clip ntawm 0.25 kg.
Vim li cas xaiv cov khoom tseem ceeb
Cov khoom siv thiab nws cov kev kho cua sov txiav txim siab seb lub clip khaws nws qhov elasticity nyob rau hauv kev khiav tsheb. Ib qho clip uas ua los ntawm cov qib hlau tsis raug yuav yog mos heev thiab poob clamping quab yuam, los yog nkig heev thiab tawg nyob rau hauv kev cuam tshuam. Qhov no yog vim li cas cov neeg yuav khoom yuav tsum ib txwm thov cov tshuaj tshuaj ntsuam xyuas, daim ntawv pov thawj hardness thiab daim ntawv qhia kev qaug zog nrog txhua tus xa khoom, thiab vim li cas kev tsim khoom yuav tsum siv lub caij nplooj ntoos hlav steel los ntawm cov neeg muab ntawv pov thawj ntev.
Kev Ntseeg Tsis Zoo
Ib qho kev xav tsis zoo yog tias txhua qhov puag ncig steel bar tuaj yeem tsim rau hauv ib qho clip. Tsuas yog lub caij nplooj ntoos hlav steel nrog tswj muaj pes tsawg leeg thiab kev kho cua sov muab qhov xav tau elasticity thiab qaug zog lub neej. Lwm qhov yuam kev yog ntseeg tias ib qho clip yog rov siv tau tom qab deformation mus tas li; thaum lub elastic ntau tshaj qhov clip yuav tsum tau hloov. Nws kuj yog qhov tsis ncaj ncees lawm los txiav txim qhov zoo ntawm cov xim saum npoo ib leeg, vim tias cov khoom siv kho tshuab los ntawm cov khoom siv thiab cov txheej txheem, tsis yog qhov kawg.
