Kev xaiv khoom thiab kev ua tau zoo ntawm Elastic Clips
Cov ntaub ntawv dab tsi feem ntau siv rau cov hlua khi elastic, thiab qhov kev ua tau zoo sib txawv thiab cov xwm txheej siv tau ntawm cov khoom sib txawv yog dab tsi?
Cov ntaub ntawv zoo sib xws rau cov hlua khi muaj xws li lub caij nplooj ntoos hlav steel xws li 60Si2Mn, 60SiCrVA thiab 55SiMnMo. 60Si2Mn muaj lub zog zoo thiab tawv, tus nqi nruab nrab, thiab tau siv dav hauv Hom I elastic clips rau kev tsheb ciav hlau zoo tib yam; 60SiCrVA ntxiv chromium thiab vanadium ntsiab nyob rau hauv lub hauv paus ntawm 60Si2Mn, nrog yield zog thiab tensile zog nce los ntawm 42% thiab 36% feem, thiab ntau dua clamping quab yuam, siv nyob rau hauv hom II thiab hom III elastic clips rau siab -ceev thiab hnyav- thauj railways; 55SiMnMo muaj kev cuam tshuam zoo heev, tsim nyog rau thaj tsam alpine, thiab tuaj yeem zam kev tawg ntawm elastic clips hauv qis- qhov kub thiab txias.
Dab tsi cuam tshuam rau lub zog clamping thiab elastic stroke ntsuas ntawm elastic clips muaj nyob rau hauv kev ua tau zoo, thiab dab tsi yog lub teb chaws tus qauv rau ntau hom elastic clips?
Lub clamping quab yuam txiav txim siab kho stability ntawm txoj kev tsheb ciav hlau. Tsis txaus clamping quab yuam yuav ua rau txoj kev tsheb ciav hlau loosen, thaum lub zog clamping ntau dhau yuav ua rau qaug zog ntawm elastic clip; lub elastic stroke qhia lub elastic deformation muaj peev xwm ntawm elastic clip, thiab ib tug me me elastic stroke tsis tau zoo nqus tsheb ciav hlau kev co. Lub teb chaws cov qauv qhia tias lub clamping quab yuam ntawm ib hom I elastic clip tsis tsawg dua 8KN, thiab elastic stroke yog ≥8mm; Lub clamping quab yuam ntawm hom II elastic clip tsis tsawg dua 10KN, thiab elastic stroke yog ≥10mm; Lub clamping quab yuam ntawm hom III boltless elastic clip yuav tsum ncav cuag ntau tshaj 12KN, thiab lub elastic stroke tsis tsawg tshaj li 11 hli kom haum raws li cov qauv kev cai siab dua.
Lub luag haujlwm txiav txim siab dab tsi yog txheej txheem kev kho cua sov ua si hauv kev ua haujlwm ntawm elastic clips, thiab dab tsi yog cov txheej txheem kev kho cua sov?
Cov txheej txheem kev kho cua sov ncaj qha txiav txim siab hardness, elasticity thiab qaug zog lub neej ntawm elastic clip, thiab tuaj yeem txhim kho cov khoom siv los ntawm kev kho cov microstructure. Cov txheej txheem ib txwm yog: ua ntej, quenching kev kho mob, cua sov lub elastic clip rau 860-880 degree, ua kom sov thiab ces txias nws sai sai nrog dej los hloov cov qauv rau hauv martensite; Tom qab ntawd ua qhov nruab nrab-kub tempering, ua kom sov ntawm 420-450℃kom tau txais cov qauv tempered troostite. Cov txheej txheem no tuaj yeem ua rau elastic clip muaj lub zog siab thiab tawv, thaum tuav cov elasticity zoo, tsis txhob deformation mus tas li thaum siv.
Dab tsi ua tsis tiav hom yog elastic clips nquag siv thaum siv, thiab yuav ua li cas tiv thaiv lawv los ntawm kev txhim kho cov txheej txheem ntau lawm?
Cov hom kev ua tsis tiav ntawm elastic clips muaj xws li qaug zog tawg, elastic degradation thiab kawg hnav. Cov kev tiv thaiv muaj xws li: ua kom zoo dua qub ntawm cov khoom siv raw, txo cov khoom tsis yog-hlau, thiab tsis txhob muaj kev ntxhov siab; adopting dov txoj kev es tsis txhob forging los txhim kho nto zoo; nruj me ntsis tswj cov cua kub thiab txias npaum li cas thaum lub sij hawm kho cua sov kom paub meej cov qauv zoo; carburizing qhov kawg ntawm elastic clip los txhim kho qhov tawv tawv thiab txo qhov hnav; Nyob rau tib lub sijhawm, 100% qaug zog kev ua tau zoo sampling tshuaj xyuas yog nqa tawm ntawm cov khoom tiav kom tshem tawm cov khoom tsis tsim nyog.
Dab tsi tshwj xeeb yuav tsum tau ua elastic clips siv nyob rau hauv cheeb tsam alpine muaj, thiab yuav ua li cas hloov lawv raws li cov ntaub ntawv thiab cov txheej txheem?
Elastic clips nyob rau hauv alpine cheeb tsam yuav tsum muaj zoo heev low-kub tej yam toughness kom tsis txhob nkig tawg los ntawm qis kub hauv qab no -30℃, thiab nyob rau tib lub sij hawm tiv thaiv corrosion los ntawm khov -thaw cycles. Hais txog cov ntaub ntawv, qis- kub resistant caij nplooj ntoos hlav steel yog xaiv, xws li ntxiv npib tsib xee rau 60Si2Mn los txhim kho qis- kub toughness; Nyob rau hauv cov nqe lus ntawm cov txheej txheem, lub quenching tuav lub sij hawm yog txuas ntxiv mus xyuas kom meej cov nplej refinement thiab txo cov sab hauv; lub tempering kub yog tsim nyog txo mus txog 400℃los txhim kho qhov qis-kub stability ntawm cov khoom; Qhov saum npoo siv Dacromet txheej los txhim kho corrosion kuj thiab hloov mus rau qhov chaw hnyav hauv thaj tsam alpine.
