Caij nplooj ntoos hlav Clip Manufacturing txheej txheem thiab kev ua tau zoo
Dab tsi yog qhov yuav tsum tau ua rau cov khoom siv tseem ceeb ntawm kev tsheb nqaj hlau?
Cov khoom tseem ceeb ntawm kev tsheb ciav hlau clips yog 60Si2Mn kub- dov caij nplooj ntoos hlav steel, uas yuav tsum ua raws li GB1222-1984 tus qauv, tsis muaj kev puas tsuaj los yog sab hauv. Cov khoom no muaj elasticity zoo heev thiab qaug zog tiv thaiv, thiab tuaj yeem tiv taus cov khoom hnyav dua tsis muaj deformation yooj yim. Qee qhov siab -kawg rail clips txais boron steel los yog chromium-molybdenum alloy steel los txhim kho tensile zog thiab huab cua tsis kam. Cov tshuaj muaj pes tsawg leeg ntawm cov khoom yuav tsum tau nruj me ntsis tswj kom ntseeg tau tias cov ntsiab lus ntawm carbon, silicon, manganese thiab lwm yam ntsiab lus raws li cov qauv, tsis txhob cuam tshuam cov kev kho cua sov nyhuv. Cov khoom siv raw yuav tsum tau soj ntsuam nruj heev kom tshem tawm cov hlau tsis tsim nyog, kom ntseeg tau tias kev ua haujlwm ntawm kev tsheb ciav hlau los ntawm qhov chaw.
Cov txheej txheem kev kho cua sov ntawm rail clips cuam tshuam li cas?
Rail clips feem ntau yog siv nruab nrab zaus cua sov tsim thiab cov txheej txheem kub quenching, thiab qee cov khoom raug ua tiav los ntawm peb - sij hawm tsim kom muaj cov qauv zoo ib yam. Kev kho cua sov tuaj yeem ua rau qhov tawv tawv ntawm cov hlua khi rau HRC44-48, thaum tuav ib qho tawv tawv hauv cov tub ntxhais, ntsuas lub zog thiab plasticity. Cov txheej txheem quenching yuav tsum tswj cov cua kub thiab txias npaum li cas kom tsis txhob overheating thiab hlawv, thiab tiv thaiv cov decarburization txheej txheej ntawm ntau tshaj 0.25mm. Tempering kev kho mob tuaj yeem tshem tawm cov kev ntxhov siab sab hauv, tsim kom muaj ib qho tempered troostite thiab sorbite microstructure, txhim kho kev qaug zog. Cov txheej txheem kev kho cua sov zoo tuaj yeem ua rau cov tsheb ciav hlau tuaj yeem tiv taus 5 lab kev sim qaug zog yam tsis muaj kev tawg, nrog cov seem deformation tsawg dua lossis sib npaug li 1.0mm.
Dab tsi yog cov haujlwm ntawm txoj kev kho saum npoo rau kev tsheb ciav hlau clips?
Qhov saum npoo ntawm rail clips xav tau kev tiv thaiv- xeb; cov txheej txheem yog fluorocarbon xim electrostatic spraying los yog sib npaug tshuab, yuav tsum dhau 240h nruab nrab ntsev tsuag tshuaj ntsuam nrog ib tug tiv thaiv theem ntawm tsis tsawg tshaj li 9. Kev kho deg tuaj yeem tiv thaiv kev tsheb ciav hlau los ntawm rusting nyob rau hauv qhov chaw ntub thiab plua plav, ncua kev pab cuam lub neej. Cov txheej txheem txau yuav tsum xyuas kom meej cov txheej txheem tsis muaj cov tshuaj tsuag los yog sagging, tsis txhob cuam tshuam qhov sib txuam ntawm cov tsheb ciav hlau thiab lwm yam khoom. Qee qhov kev tsheb ciav hlau kuj tau txais ob npaug - txheej tiv thaiv Dacromet + epoxy resin los txhim kho corrosion kuj, hloov mus rau qhov hnyav ib puag ncig xws li ntug hiav txwv dej thiab alpine. Qhov saum npoo- kho cov hlua khi yuav tsum muaj qhov hnav zoo tiv thaiv kom tsis txhob muaj txheej txheej txheej thaum nruab thiab siv.
Dab tsi yog qhov geometric dimension qhov yuav tsum tau rau kev tsheb ciav hlau clips?
Tus tsim buckling stroke ntawm rail clips yog 13mm, thiab yuav tsum tsis muaj qhov pom tseeb creases nyob rau hauv me me arc ib feem; nws yuav tsum yog tangent thaum leaning tawm tsam ib txoj hauj lwm nrog ib tug φ17.5mm lub tog raj kheej. Qhov ntev ntawm txhua qhov yuav tsum ua raws li cov qauv kos duab, thiab qhov sib txawv yuav tsum tau tswj nyob rau hauv qhov kev tso cai kom tsis txhob cuam tshuam rau kev sib kis ntawm buckling quab yuam. Qhov saum npoo ntawm rail clips yuav tsum tsis muaj kab nrib pleb, burrs los yog pom tseeb khawb, thiab cov indentations tshwm sim los ntawm kev tsim cov cuab yeej yuav tsum du. Lub gauge baffles thiab baffle rooj zaum yuav tsum nruj abutted; tus naj npawb ntawm qhov khoob loj dua 2 hli yuav tsum tsis pub tshaj 6%, thiab yuav tsum tsis muaj qhov tsis ua haujlwm tas mus li. Geometric dimension precision yuav tsum tau soj ntsuam los ntawm cov cuab yeej tshwj xeeb kuaj kom ntseeg tau tias txhua pawg ntawm cov khoom ua tau raws li cov qauv.
Dab tsi yog qhov sib txawv ntawm kev hloov pauv ntawm ntau hom kev tsheb ciav hlau clips?
W-type rail clips muaj cov qauv yooj yim thiab yooj yim rau nruab, haum rau cov kev tsheb ciav hlau zoo tib yam thiab kev tsheb ciav hlau hauv nroog, nrog kev ruaj khov buckling quab yuam ntawm 16-20kN. E- hom rail clips muaj zog buckling loj (ntau tshaj 20kN), haum rau siab - kev tsheb ciav hlau ceev thiab hnyav- cov kab tsheb thauj mus los, muaj zog tiv thaiv rau sab nraud. Hom Ⅴ rail clips yog tsim tshwj xeeb rau cov kab alpine thiab toj siab, nrog lub zog tensile tshaj 1100MPa, muaj peev xwm tiv taus qhov kub thiab txias thiab lub zog loj load. Tus kheej-locking rail clips txhim khu kev tiv thaiv kev ua haujlwm los ntawm kev tsim qauv tshwj xeeb, haum rau cov kab roob nrog kev sib hloov qhov thiab txuas hniav. Thaum xaiv rail clip hom, nws yog ib qho tsim nyog yuav tsum txiav txim siab ua ke nrog cov kab ceev, qag load thiab ib puag ncig kom ntseeg tau tias kev sib txuam nrog lwm cov khoom ntawm lub fastening system.
