Txoj Haujlwm ntawm Elastic Bar
Lub elastic bar tuav lub tsheb ciav hlau taw tawm tsam lub hauv paus phaj nrog lub zog clamping thiab ua kom lub zog ntawd dhau los ntawm ntau lab lub voj voog. Thaum lub log hla dhau, qhov clip deflects thiab springs rov qab, yog li nws cov khoom siv yuav tsum muab cov kev txwv siab elastic nrog kev qaug zog, thiab nws qhov chaw yuav tsum muaj sia nyob corrosion tsis tas yuav poob. Ob lub tswv yim tsim uas txiav txim siab clip zoo yog qib steel thiab kev kho cua sov, thiab ob qho tib si tshwm sim hauv qhov kev lees paub: clamping quab yuam, teeb tsa mus tas li tom qab rov qab deflection, qaug zog lub neej thiab kev ua haujlwm corrosion. Cov neeg yuav khoom uas sib piv tsuas yog tus nqi ntawm cov clips tsis nco txog tus nqi sib txawv uas tshwm sim hauv kev khiav: ib qho clip uas poob clamping quab yuam los yog tawg tom qab peb xyoos yuam cov neeg laib saib xyuas los hloov nws ntawm kab nyob.
60Si2MnA piv rau 55SiCr Spring Steel
| Khoom | 60 Si2MnA | 55 Sib |
|---|---|---|
| Hom muaj pes tsawg leeg | Carbon thiab manganese ntxiv dag zog | Ntxiv chromium rau hardenability thiab corrosion kuj |
| Elastic txwv thiab yield zog | High, mature processing, nruab nrab nqi | Piv txwv li, nrog ntau yam hardness faib |
| Kev qaug zog | Zoo rau cov kab nrawm nrawm | Zoo dua nyob rau hauv ntev - lub sij hawm vibration load, txo kev pheej hmoo tawg |
| Corrosion kuj | Txuj | Txhim kho los ntawm chromium |
| Zoo tshaj plaws | Cov pa hluav taws xob ceev, tus nqi - cov haujlwm tseem ceeb | Siab -ceev, hnyav- thauj thiab ntug hiav txwv kab |
Txoj kev kho cua sov sib txawv: 55SiCr xav tau qhov tseeb quench thiab temper voj voog los txhim kho lub zoo tempered microstructure uas muab ruaj khov clamping quab yuam, thaum 60Si2MnA yog ntau zam txim nyob rau hauv ntau lawm. Rau tib lub geometry, 55SiCr clip tuav nws lub zog clamping zoo dua nyob rau lub sijhawm thiab tiv thaiv kev ntxhov siab hauv qhov chaw ntub dej. Kev xaiv yog qhov sib npaug ntawm cov kab khiav hauj lwm siv, txij nkawm ncua sij hawm thiab tus nqi; ntawm ib ceg kab nrog lub teeb tsheb, 60Si2MnA feem ntau yog cov lus teb nyiaj txiag.
Kev Tiv Thaiv Qhov Nto
| Kev kho mob | Hom lub neej nyob rau hauv qhib huab cua | Zoo tshaj plaws |
|---|---|---|
| Dub oxide tiav | 2 rau 3 xyoos | Qhuav hauv av theem nrab kab, tiv thaiv kom hniav zoo nkauj |
| Hluav taws xob-galvanizing | 3a5 xya | Moderate humidity, nyias txheej txheej |
| Kub-dip galvanizing | 5a8 xya | Humid cov kab tseem ceeb, tuab zinc txheej |
| zinc flake txheej | 10 xyoo thiab ntau dua | Siab -ceev, ntug hiav txwv thiab hnyav- cov kab |
| Zinc infiltration | 8 mus rau 12 xyoo | Hnyav- cov kab tsheb thauj mus los, kev pabcuam zoo ntawm cov duab nyuaj |
Dub oxide yog pheej yig tab sis muaj yuav luag tsis muaj kev tiv thaiv corrosion tiag. Kub-dip galvanizing muab cov txheej tuab, ruaj khov tab sis tuaj yeem cuam tshuam rau lub caij nplooj ntoo hlav hlau yog tias tsis muaj dej da dej kub. zinc flake txheej yog nyias, sib xws thiab tsis hloov cov clip elasticity, uas yog vim li cas nws thiaj li tau teev rau siab -ceev thiab ntug hiav txwv khiav qhov twg corrosion thiab qaug zog ua ke. Zinc infiltration diffuse zinc rau hauv txheej txheej thiab yog ib qho kev xaiv muaj zog rau hnyav-haul hardware. Txawm li cas los xij, qhov kev lees paub yuav tsum suav nrog cov txheej tuab thiab cov ntsev tsuag cov xuab moos, thiab cov txheej txheem yuav tsum muaj sia nyob ntawm qhov clip deflection yam tsis muaj cracking.
WJ-7 Ballastless Track System
Ntawm Suav siab -ceev ballastless taug qab WJ-7 fastening system siv lub koov-zoo li tus elastic bar nrog elastic caj npab ntawm ob sab, ua hauj lwm nrog gauge baffles thiab bolts los kho txoj kev tsheb ciav hlau. Nws cov qauv tsim muaj txiaj ntsig qhia txog qhov niaj hnub clip yuav tsum tau xa: thawj zaug clamping quab yuam siab tshaj 13 kN nrog clamping quab yuam attenuation li ntawm 10 feem pua tom qab siv tas mus li, elastic rov qab uas tuav geometry nyob rau hauv high-frequency vibration, thiab ib tug qhov siab hloov ntawm rho tawm 4 mus rau ntxiv 26 hli los ntawm kev hloov kho shims nyob rau hauv lub rail. Cov clip no yog ua los ntawm 55SiCr caij nplooj ntoos hlav steel nrog kev kho cua sov, thiab nws raug ntsia thiab tshem tawm nrog cov cuab yeej tshwj xeeb rau kev kho ceev. Lub kaw lus yog fastened mus rau qhov khiav slab los ntawm screws rau hauv lub tes tsho precast, thiab tag nrho lub rooj sib txoos raug txheeb xyuas los ntawm kev lees paub ntawm cov txheej txheem fastening. Cov lej no yog qhov kev lees paub tsim qhov tseem ceeb, thiab daim ntawv pov thawj xa tawm yuav tsum lees paub lawv.
Fatigue Life Factors thiab Optimization
Clip qaug zog lub neej yog tswj hwm los ntawm plaub pawg ntawm yam. Cov khoom zoo los ua ntej: suav nrog thiab cov nplej ntxhib ua rau lub neej qaug zog. Kev ua haujlwm yog qhov thib ob: tawg, burrs thiab decarburization los ntawm kev kub kub tsim cov ntsiab lus kev ntxhov siab. Kev teeb tsa yog thib peb: nyob rau hauv -torque cia cov clip ua haujlwm xoob thiab dhau -torque overstresses nws, thiab tsis zoo haum ntawm clip thiab gauge baffle tso lub zog tsis sib xws ntawm ib ceg. Qhov chaw ib puag ncig yog plaub: cov av noo thiab corrosive cov neeg ua haujlwm nrawm nrawm nrawm nrawm nrawm. Kev ntsuas kev ua kom zoo ua raws li ncaj qha: qhia meej lub caij nplooj ntoos hlav hlau uas muaj kev tswj hwm purity, siv precision sib sau thiab tswj kev kho cua sov, nruab rau lub zog torque nrog lub ntsuas ntsuas ntsuas, xaiv txheej txheej rau qhov chaw, thiab tshuaj xyuas cov clips ib ntus kom qaug zog - qhov chaw puas raug hloov ua ntej lawv ua tsis tiav. Torque tswj ib leeg tshem tawm ib feem loj ntawm kev ua tsis tiav ntawm qhov tsis tiav.
Hnyav -Haul Clip Requirements
Hnyav- cov kab tsheb thauj mus rau qhov loj tshaj plaws thiab qhov kev vibration phem tshaj plaws, yog li cov qauv tsim cov cai nruj dua: clamping quab yuam siab tshaj 15 kN yog li cov tsheb ciav hlau tsis tuaj yeem txav mus rau hauv cov tsheb ciav hlau hnyav, lub caij nplooj ntoos hlav steel xws li 55SiCr nrog kev lav phib xaub lub neej tsawg kawg yog tsib xyoos, thickened elastic caj npab thiab ib qho kev ua kom zoo tshaj plaws arch ometry rau kev sib cuag nrog kev ntxhov siab ntau dua. concentration. Kev tiv thaiv saum npoo yog zinc flake txheej los yog zinc infiltration kom muaj sia nyob ntawm qhov hnyav ib puag ncig, thiab qhov tseeb ntawm qhov ntev yog siab dua vim tias qhov clip yuav tsum phim lub ntsuas baffle thiab puag phaj precisely. Qhov kev lees paub rau qhov hnyav-haul clip suav nrog kev kuaj xyuas lub zog clamping, qhov kev sim qaug zog ntawm qhov teev cov load spectrum, thiab kuaj corrosion.
Thaum twg kuv yuav tsum xaiv 60Si2MnA hloov 55SiCr?
Xaiv 60Si2MnA rau cov kab nrawm nrawm, ib puag ncig qhuav thiab tus nqi - cov haujlwm tseem ceeb uas qhov kev qaug zog thiab kev xeb ntawm 55SiCr tsis xav tau. Xaiv 55SiCr rau siab -ceev, hnyav- thauj thiab ntug hiav txwv kab uas clamping quab yuam stability thiab corrosion kuj txiav txim siab nqi kho.
Cov txheej twg yog qhov zoo tshaj plaws rau kev tsheb ciav hlau ntug hiav txwv?
zinc flake txheej muab kev tiv thaiv ntev tshaj plaws rau lub caij nplooj ntoos hlav steel clips hauv chloride atmospheres, nrog rau kev pab cuam lub neej saum kaum xyoo hauv cov xwm txheej raug. Nws yog nyias txaus kom tsis txhob cuam tshuam cov clip elasticity thiab tsis muaj kev pheej hmoo rau tempering lub caij nplooj ntoos hlav steel txoj kev kub -dip processing tau.
Vim li cas clip clamping quab yuam poob lub sijhawm?
Clamping quab yuam poob los ntawm elastic so ntawm lub caij nplooj ntoos hlav steel, nto corrosion uas txo qhov zoo seem, thiab mus tas li los ntawm overload cycles. Kev kho cua sov zoo thiab cov txheej txheem kom zoo qeeb tag nrho peb, uas yog vim li cas qhov kev txwv attenuation tau sau rau hauv qhov system specification.
WJ-7 fastening system siv rau dab tsi?
WJ-7 yog lub ballastless track fastening system rau Suav high-speed railways. Nws arch clip, gauge baffles thiab kho shims tuav lub tsheb ciav hlau ntawm lub pob zeb slab, nrog rau qhov siab hloov ntawm rho tawm 4 mus rau ntxiv rau 26 hli los kho cov geometry.
Yuav ua li cas kuv thiaj li pom qhov qaug zog- clip puas nyob rau hauv txoj kev?
Saib rau cov kab xeb ntawm cov ntiv taw ntiv taw thiab lub koov khoov, uas qhia txog kev txhim kho tawg, mloog cov xoob xoob ntawm ib qho clip uas tau poob lub zog clamping, thiab xyuas cov ntiv taw sib txawv ntawm qhov system specification. Hloov cov clips puas nyob rau hauv pab pawg nyob rau hauv lub teeb fastening cuam tshuam.
