Dab tsi yog E-Shape Elastic Rail Clips
E-puab elastic rail clips yog siv nrog cov pob zeb pw tsaug zog kom nrawm rau ob sab ntawm txoj kev. Cov clip yog tsim nyob rau hauv cov duab ntawm tsab ntawv E thiab ua hauj lwm elastically, nias lub tsheb ciav hlau ko taw tiv thaiv lub hauv paus phaj nrog ib tug tas mus li quab yuam. Vim hais tias cov clip khoov thiab rov qab nyob rau hauv nws cov elastic ntau yam, nws absorbs lub dynamic loads hla lub tsheb ciav hlau thiab ua rau lub tsheb ciav hlau ruaj ntseg nyob rau hauv ob qho tib si lateral thiab longitudinal rog.
Vim li cas Kub Forged Spring Steel
Rail clips feem ntau yog ua los ntawm forged caij nplooj ntoos hlav steel tsim los ntawm cov txheej txheem kub forging, nyob rau hauv qhib tuag los yog kaw tuag. Cov khoom siv zoo li thaum cov hlau rhuab yog tsim ntawm forging kub, thiab forged qhov chaw yog suav hais tias zoo dua qhov chaw ua los ntawm lwm yam hlau txheej txheej txheem vim hais tias ntawm lawv feem ntau uniform microstructure. Uniform grain flow muab cov clip sib xws hardness, toughness thiab qaug zog tus cwj pwm nyob ib ncig ntawm khoov qhov twg stresses concentrate.
E-Series Clip Specifications
E-series npog E1609, E1809, E1813, E2001, E2007, E2009, E2039, E2055, E2056 thiab E2063 qauv, tag nrho cov tsim los ntawm 60Si2MnA caij nplooj ntoos hlav steel. Txhua tus qauv yog ntsuas ntawm qhov tsawg kawg nkaus clamping load ntawm 950 kg nrog ib tug hardness ntawm 44 mus rau 48 HRC. 16 hli clip hnyav 0.43 kg, 18 mm clips hnyav 0.61 txog 0.62 kg thiab 20 mm series hnyav 0.80 kg ib thooj. Clips kuj tuaj yeem tsim rau cov neeg siv khoom kos duab.
Caij nplooj ntoos hlav steel qib thiab muaj pes tsawg leeg
Ntxiv rau 60Si2MnA, qib 60Si2CrA, 55Si2Mn thiab 38Si7 muaj. 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 ntxiv chromium ntawm 0.70 mus rau 1.00 feem pua, thiab qib 38Si7 nqa carbon 0.35 mus rau 0.42 feem pua nrog silicon 1.50 rau 1.80 feem pua. Phosphorus thiab sulfur raug txwv rau 0.03 feem pua hauv txhua qib, thiab cov hlau ua raws li DIN 17221, BS 970 thiab GB / T 1222.
Fatigue Life thiab Surface Protection
Lub neej qaug zog ntawm cov clips nyob ntawm txoj kab uas hla: 18 hli clips tiv taus 3 lab lub voj voog yam tsis muaj kev tawg, thiab 20 hli clips tiv taus 5 lab lub voj voog yam tsis muaj kev tawg. Cov kev xaiv saum npoo muaj xws li cov roj av dawb, oxide dub, xim pleev xim, kub dip galvanizing thiab zinc plating. Clips tuaj yeem ua ntej sib dhos nrog T-bolts thiab ntxhua khaub ncaws ua ib qho kev pabcuam ntxiv, thiab lawv tau ntim rau lub sijhawm txuag thiab kev thauj mus los nyab xeeb.
Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Zoo
Kev ua tiav kev tswj hwm zoo suav nrog kev tsim cov tsheb ciav hlau los ntawm cov khoom siv raw khoom mus rau daim ntawv thov tiav. Pab pawg kws tshaj lij tshuaj xyuas txhua tus txheej txheem ntawm cov kab ntau lawm thiab xyuas cov khoom tawm ntawm lub sijhawm tsis tu ncua, kom qhov tseeb qhov tseeb, qhov nyuaj thiab qhov chaw ntawm qhov chaw raug lees paub ua ntej xa. Qhov kev qhuab qhia no txhawb nqa loj ntim khoom rau ob qho tib si export thiab domestic railway project.
Ib qho kev xav tsis zoo yog tias cov txheej txheem forging yog qhov tsis tsim nyog vim tias daim clip stamped zoo li qub. Forging tsim cov qauv microstructure uas muab cov clip nws qhov kev ua haujlwm qaug zog, yog li cov txheej txheem yog ib feem ntawm cov lus qhia tshwj xeeb, tsis yog qhov nthuav dav. Lwm qhov yuam kev yog xav tias tag nrho cov clips ntawm ib tus qauv qhia tib yam zoo; cov khoom siv hlau, kev kho cua sov thiab cov ntaub ntawv tshuaj xyuas yuav tsum raug txheeb xyuas. Nws tseem yog qhov tsis ncaj ncees rau kev teeb tsa cov clips yam tsis tau kuaj xyuas lub rooj zaum tiv thaiv lub hauv paus phaj thiab rail ko taw.
