Lub tsheb ciav hlau elastic clip yog lub caij nplooj ntoos hlav steel fastener siv los tiv thaiv kev tsheb ciav hlau mus rau lub hauv paus pw tsaug zog. Clips ntawm hom no yog siv nyob rau hauv fastening systems uas yuav tsum tau ib tug tsawg kawg nkaus tu thiab paub txog lawv cov ntiv taw muaj zog load, uas tiv thaiv cov txheeb ze txav ntawm txoj kev tsheb ciav hlau thiab cov pw tsaug zog. Lawv feem ntau siv nrog cov pob zeb pw tsaug zog thiab tuaj yeem kho nrog cov fittings ntxiv thiab lub hauv paus phaj. Kab lus no tsom rau cov clips tsim los ntawm 38Si7 caij nplooj ntoos hlav steel.
Khoom Properties ntawm 38Si7 Caij nplooj ntoos hlav hlau
38Si7 yog silicon alloy caij nplooj ntoos hlav steel nrog cov ntsiab lus carbon ntawm 0.35 mus rau 0.42 feem pua, silicon ntawm 1.50 mus rau 1.80 feem pua thiab manganese ntawm 0.50 mus rau 0.80 feem pua, nrog phosphorus thiab sulfur txwv rau 0.03 feem pua. Cov ntsiab lus ntawm silicon siab muab cov kev txwv siab elastic thiab kev qaug zog zoo, thaum cov ntsiab lus carbon nruab nrab muab cov qauv zoo thiab kev kho cua sov. Tom qab hardening thiab tempering, 38Si7 steel ua tiav lub hardness thiab toughness yuav tsum tau rau rail clips ua hauj lwm nyob rau hauv alternating dua kev nyuaj siab. Cov qib steel ua raws li cov qauv siv xws li DIN 17221, BS 970 thiab GB / T 1222.
Hardness thiab Fatigue Performance
38Si7 railway elastic clips raug kho kom sov rau qhov nyuaj ntawm 44 txog 48 HRC. Ntawm qhov hardness no, cov clip muab qhov xav tau clamping quab yuam thaum khaws cov toughness txaus los tiv thaiv kev cuam tshuam thiab tsis txhob tawg tawg. Nyob rau hauv kev ntsuam xyuas qaug zog, clips nrog ib txoj kab uas hla hauv qab 20 hli tiv taus 3 lab lub voj voog yam tsis muaj kev tawg, thiab cov clips ntawm 20 hli inch withstand 5 lab cycles tsis tawg. Kev sib xyaw ua ke ntawm hardness, nto zoo thiab txhim khu kev qha yog qhov tseem ceeb kom ua tiav lub neej qaug zog tsim.
Common Clip Sizes
| Clip chav kawm | Hlau txoj kab uas hla | Hardness |
|---|---|---|
| Lub teeb clip | 13 hli | 44-48 HRC |
| Nruab nrab clip | 19 hli | 44-48 HRC |
| Hnyav clip | 20 mm | 44-48 HRC |
| Hnyav clip | 20 mm | 44-48 HRC |
| Ntxiv hnyav clip | 22 hli | 44-48 HRC |
Lwm cov elastic clips tuaj yeem tsim tau raws li cov neeg siv khoom kos duab, nrog tib cov khoom siv thiab hardness ntau yam.
Yuav ua li cas cov Clip ua hauj lwm nyob rau hauv lub Fastening System
Cov clip yog ntsia rau ntawm lub hauv paus phaj los yog lub xub pwg embedded nyob rau hauv lub pob zeb pw tsaug zog, thiab nws bent ntiv taw nias rau ntawm txoj kev tsheb ciav hlau ko taw. Lub elastic deformation ntawm cov clip tsim cov ntiv taw hnyav uas tuav cov tsheb ciav hlau ruaj khov, thaum qhov yooj yim ntawm cov clip absorbs ntsug thiab sab qaum los ntawm cov tsheb ciav hlau hla. Lub kaw lus fastening kuj muaj xws li ib tug khi phaj, rail insulator, ntsia hlau spikes los yog dev spikes, thiab ib tug rail pad. Lub khi phaj feem ntau yog ua los ntawm Q235 steel los yog hlau ductile, lub rwb thaiv tsev ntawm PA66 reinforced iav fiber ntau, thiab cov ntaub ntawv ntawm cov roj hmab, EVA lossis lwm yam khoom siv elastic.
Kev kho saum npoo
Cov kev kho deg muaj xws li cov roj ua kom tiav, oxide dub thiab xim pleev xim, raws li cov neeg siv khoom xav tau. Lub tiaj oiled thiab oxide dub tiav yog kev lag luam rau cov huab cua qhuav, thaum pleev xim muab kev tiv thaiv corrosion ntxiv. Rau qhov chaw ntub dej thiab ntug hiav txwv, kub -dip galvanizing tuaj yeem txiav txim siab, txawm hais tias cov txheej txheem yuav tsum tau tswj xyuas kom muaj kev qaug zog ntawm lub caij nplooj ntoos hlav hlau.
Kev txhim kho thiab tu
Txhim kho qhov clip nrog cov cuab yeej kom raug kom tus ntiv taw nias lub tsheb ciav hlau ntawm txoj haujlwm tsim, thiab xyuas kom meej tias cov insulator thiab cov ntaub qhwv tau raug zaum. Siv lub zog uas tau teev tseg thiab tsis txhob cuam tshuam kev thauj khoom. Thaum lub sij hawm soj ntsuam, xyuas cov clips rau cov kab nrib pleb, xeb, poob ntawm ntiv taw load thiab hloov chaw, thiab hloov cov clips puas sai. Xyuas lub torque ntawm cov ntsia hlau spikes thiab hloov hnav insulators thiab ntaub qhwv raws li xav tau.
Kev Ntseeg Tsis Zoo
Ib qho kev xav tsis zoo yog qhov nyuaj dua ib txwm ua tau zoo dua. Hardness saum toj no ntau yam ua rau muaj kev pheej hmoo ntawm nkig tawg, thaum hardness hauv qab no txo cov clamping quab yuam. Lwm qhov kev xav tsis zoo yog qhov clip ib leeg muab tag nrho fastening; Nyob rau hauv qhov tseeb, lub hauv paus phaj, insulator, ncoo thiab spikes tag nrho cov pab rau lub system kev ua tau zoo. Ib txhia kuj ntseeg tias clips yeej tsis xav tau kev saib xyuas; nyob rau hauv qhov tseeb, lawv ua hauj lwm nyob rau hauv rov qab kev nyuaj siab thiab yuav tsum tau soj ntsuam tsis tu ncua.
