Xa abantu abaninzi besiva 'i-stainless steel shaft roller', baba nomfanekiso we-cylinder emenyezelayo, engenakonakala. Leyo yimbono yokuqala ephosakeleyo. Inyani imalunga nokulawula okulindelweyo-ukuqonda ukuba 'i-stainless' yintsapho, ayisosiqinisekiso, kwaye unxibelelwano phakathi kweshafti kunye ne-roller ephantsi komthwalo kulapho ubunjineli bokwenyani buqala khona, okanye rhoqo, lusilela.
I-Material ayilobali lonke
Asigqibekanga ukuya kuma-304 okanye kwi-316 ngokuxhathisa umhlwa, ngokuqinisekileyo. Kodwa ndibone iirola ezenziwe ukusuka kwi-316L entle zisilela kwangaphambi kwexesha kumthwalo ophezulu, usetyenziso olunesantya esisezantsi kuba umntu akabuhoyanga ubunzima kunye nokunganyangeki. I-shaft yayinzima ngakumbi, isebenza njengefayile. Ukhetho luhlala lujika phakathi kwento efana ne-440C ngenxa yobunzima bayo obuphezulu kunye nesakhono sokuthwala, kunye ne-machineble ngakumbi kodwa ethambileyo 304. Lurhwebo-off. Amava e-QSY kunye ne-alloys ezikhethekileyo ezifana ne-nickel-based based environments ezigqithiseleyo zikwenza ukuba ucinge-ngamanye amaxesha isisombululo 'se-stainless steel shaft roller' kwisityalo sekhemikhali asiyiyo i-stainless engcono, kodwa inkqubo yezinto eziphathekayo ehluke ngokupheleleyo.
Emva koko kukho ukukhangela. Ayizizo zonke iintsimbi zentsimbi ezenziwe ngokulinganayo. Siye saba nebhetshi kumthengisi omtsha kwiminyaka embalwa edlulileyo. Yenziwe kakuhle, yakhazimliswa yade yafikelela kwisipili. Kodwa phantsi kovavanyo lwe-ultrasonic, ukubandakanywa okuncinci kubonisiwe. Kwiqhekeza lokuhlobisa, lilungile. Kwi-roller kumgca wokucubungula iphepha eliqhubekayo? Indawo enokwenzeka yokwaphuka. Yiyo loo nto amava asisiseko enkampani abalulekile. Xa umenzi wezinto ezifana neQingdao Qiangsenyuan Technology Co., Ltd. ethetha malunga neminyaka engama-30 ekwenziweni nasekuchubeni, ayilonani nje. Yikhowudi yokuba nekhonkco lokubonelela ngemathiriyeli evavanyiweyo kunye nokwazi apho unakho kwaye awukwazi ukusika iikona.
Unyango lobushushu lutshintsho oluthe cwaka. Irola inokuguqulwa kwisitokhwe sebha esigqibeleleyo, kodwa ngaphandle komjikelo ochanekileyo we-thermal-isisombululo sokunciphisa uxinzelelo, mhlawumbi imvula ibenzima kwibakala le-17-4 PH-ukuzinza kwayo komda phantsi kwebhayisekile eshushu kukungcakaza. Ndikhumbula umgca wokupakisha ukutya apho iirola zazithi ngokuthe ngcembe 'zigobe' kwiinyanga zokucoca umphunga kunye nokuhlamba okushushu. Unobangela yayingelulo uyilo; yayiyi-roller eyi-304 eyenziwe ngomatshini elahlekileyo yozinzo olufanelekileyo.
Ukuchaneka nguMsebenzi weNkqubo
Apha kulapho indawo 'yeshaft' 'yerola yeshaft yentsimbi' iba baluleke kakhulu. Ujongano. Unokuba ne-roller egqibeleleyo, kodwa ukuba ukunyamezela, ukujikeleza, kunye nokugqitywa komphezulu akuhambelani ne-shaft, uyakhathazeka, ukunxiba, kunye nokungcangcazela. Kwizicelo ezihamba ngesantya esiphezulu, sithetha ngokunyamezelana okuyincoko phakathi kokusila kunye nokuhlonitshwa, hayi nje i-CNC lathe pass.
Umatshini we-CNC ufumana ijometri echanekileyo, kodwa isenzo sokugqibela sihlala sisenziwa ngesandla. Umntu onobuchule odibanisa i-shaft kwi-roller yayo, evakalelwa yinto encinci yokutsala, usebenzisa i-blueing ukujonga iipateni zoqhagamshelwano. Apha kulapho i-automation ecocekileyo ibetha eludongeni. Kwindawo yabo, tsngtaocnc.com, badwelisa umatshini we-CNC ecaleni kotyalo-mali. Loo ndibaniselwano iyaxela. Kuthetha ukuba banokuqonda ukuba i-roller inokuqala njengokubunjwa kwe-net-shape yeejometri ezintsonkothileyo (ezineetshaneli zokupholisa zangaphakathi, umzekelo) kwaye emva koko igqitywe ukuya kwinqanaba le-micron ngokuchanekileyo kwi-CNC. Oko kudityaniswa kwenkqubo ngundoqo ekusebenzeni kunye neendleko.
Umgibe oqhelekileyo kukuchaza ngokugqithisileyo. Ayiyiyo yonke i-roller efuna i-Ra 0.2 mirror finish. Kwizicelo ezininzi zokuhambisa, indawo eguqulwe kakuhle (i-Ra 1.6 ukuya ku-3.2) kunye ne-chamfers efanelekileyo ingaphezulu kweyoneleyo kwaye inciphisa iindleko. Ukuzingca ngepolishi egqibeleleyo ngamanye amaxesha kunokufihla amanqaku ezixhobo ezingaphantsi komhlaba eziye zibe zizigxina zoxinzelelo. I-spec sheet kufuneka iqhutywe ngumsebenzi, kungekhona i-aesthetics.
Iintsilelo ezihlala zihleli nawe
Esona sifundo sam endisikhumbulayo sasivela kwisicelo saselwandle. Iirola ze-shaft zensimbi ezingenasici kwinkqubo yokukhokela intambo. Sisebenzise i-316, i-machine engenakulinganiswa, i-press-fit-fit. Zaba ngumhlwa kwiinyanga. Ayingomhlwa jikelele, kodwa kukudleka kwemingxuma kwisiphambuka sokucinezela naphantsi kwetywina. Amanzi amileyo, aphelelwe yioksijini adala i-microenvironment i-316 engakwazi ukuyiphatha. Ukulungisa ibingengomsebenzi womatshini ongcono; yayiyila ngokutsha ijiyometri yetywina kwaye ichaza umgangatho ophezulu ongenastainless kunye nemolybdenum engaphezulu yojongano oluthile. Indifundise ukuba ndingaze ndijonge icandelo ndodwa.
Enye yaba kukudinwa. Irola kumatshini wokushicilela, ngokuxhomekeke kwimithwalo yempembelelo yomjikelo. Uhlalutyo lokungaphumeleli lubonise i-radius ebukhali yenguqu apho i-roller idibene ne-flange. Ukunyuka koxinzelelo lwakudala. Umzobo wawufuna iradiyasi eyi-R2, kodwa kumgangatho wevenkile, isixhobo senze into ekufutshane ne-R1.5 enophawu oluncinane lwesixhobo. Oko kuphambuka kuncinci, ngaphezulu kwezigidi zemijikelo, kwakwanele. Ngoku, ndine-paranoid malunga nokuhlolwa kweradiyasi kunye neprofayile yomphezulu walo naliphi na ilungu lomthwalo oguqukayo.
Ke kukho impazamo yendibano elula. Ndibone irola elunge ngokugqibeleleyo yonakaliswe ngumntu osebenzisa isando sokuyicinezela eshaftini, ikrazula ibhore. Okanye i-inverse, ukufudumeza i-roller ukuze ifakwe kwi-shaft kwaye iyicime ngokungazi, ukuvalela kwiingcinezelo. Eyona mveliso igqwesileyo inokupheliswa ngemizuzu kumgangatho wefektri. Ababoneleli abalungileyo bahlala benika imiyalelo ecacileyo efanelekileyo, nto leyo ebonisa ukuba bayibonile imiphumo.
Ukudityaniswa namanye aMalunga
I-roller ayisebenzi yodwa. Kumdaniso oneebheringi, amatywina, kunye nezinto zokuthambisa. Chaza i-roller eqinile kakhulu kodwa idibanise ne-bronze bushing ethambileyo? Uya kuphelelwa lixesha. Izinto eziphathekayo kunye nobunzima kufuneka sibe sisigqibo senkqubo. Kwiibheringi ezitywiniweyo, ukugqitywa komphezulu wejenali ye-shaft roller kunye nokunyamezelana kubaluleke kakhulu ukunqanda ukunxitywa kwemilebe.
Ukuthambisa yenye inkonkxa yeentshulube. Ezinye iigrisi zebakala lokutya azidlali kakuhle ngeentsimbi ezithile ezingenasici phantsi koxinzelelo oluphezulu. Unokufumana uxinzelelo olungaphezulu. Yingxaki ye-niche, kodwa iyenzeka. Xa usebenza nomvelisi okwaphatha iialloys ezikhethekileyo, njenge-QSY isenza ngecobalt kunye ne-nickel alloys, icebisa ukuba baqhele ukucinga ngezi ngxaki zintsonkothileyo zokusebenzisana kwezinto, hayi nje ukwenza inxalenye ezimeleyo.
Ulungelelwaniso. Ngumbulali okruqulayo, osisiseko. Unokuchitha intywenka yemali kwezona zichanekileyo iirola zensimbi ezingenasici, kodwa ukuba i-shafts ezimbini abaqhuba kuzo azilungelelaniswanga ngesiqingatha sedigri, uya kufumana ukulayishwa komphetho, ukunxiba kwangaphambi kwexesha, kunye nokusetyenziswa kwamandla okwandisiweyo. Eyona nto isebenzayo kukuba umatshini we-roller bores kunye nobuso kwi-setup efanayo ukuqinisekisa i-perpendicularity, kwaye ke, ngokubaluleke kakhulu, uqinisekise ukuba umfakeli unezixhobo kunye nolwazi lokulungelelanisa indibano yokugqibela.
Ukusasazwa nini, Ukwenziwa nini kuMatshini ukusuka kwiBar
Olu lubizo lokugweba olungundoqo. Kwi-roller elula, eqinile, umatshini ovela kwisitokisi sebha yensimbi engenasici ngokuqhelekileyo iyona nto ichanekileyo kwaye ineendleko. Ufumana ukwakheka okulungileyo kweenkozo kunye neempawu ezinokuqikelelwa. Kodwa masithi ufuna i-rola enkulu yedayamitha enomgongxo wokunciphisa inertia, okanye enye enothungelwano oluntsonkothileyo lwangaphakathi lolwelo lokudlulisa ubushushu. Emva koko, ukungunda kweqokobhe okanye ukuphosa utyalo-mali kuba lukhetho olunyanzelisayo.
Inkampani efana neQiangsenyuan, enobuchwephesha obubini, inokufikelela koku ngokubuza malunga nomthamo wesicelo, iimfuno zokusebenza, kunye neendleko zizonke. Ukwenziwa kotyalo-mali kunokuvelisa indawo ekufutshane ne-net-shape enenkunkuma encinci yeejiyometri ezintsonkothileyo. Oko kugalelwa rhabaxa ke ngoko kuchanekileyo-oomatshini kwi-CNC ukufumana iindawo ezibalulekileyo-i-bore, i-OD, ubuso-ukuba icaciswe. Le ndlela ye-hybridi inoqoqosho kakhulu kunokukhupha ibha enkulu eyomeleleyo.
Umngcipheko ngeerola eziphosiweyo ngumgangatho we-Foundry. Ukufakwa, i-porosity, i-shrinkage cavities. Kulapho iminyaka engama-30 yamava okusasaza ayingomgca wokuthengisa. Kuthetha ukuba bona (okanye nayiphi na isiseko esithembekileyo) banolawulo lwenkqubo-indlela efanelekileyo yokungena kunye noyilo lokunyuka, ulawulo lobushushu lokungunda, ukuhlolwa kwe-post-casting njenge-X-reyi okanye i-dayi yokungena-ukunciphisa loo mingcipheko. Awuthengi nje inxalenye; uthenga isakhono sabo sokulawula inkqubo ngezinto eziguquguqukayo zendalo.
Ukuyisonga: ICandelo, hayi iNtengiso
Ngoko, a intsimbi ye-shaft roller ayisonto nje ekwibhili yezixhobo. Yindawo apho isayensi yezinto eziphathekayo, uyilo lomatshini, ukuveliswa okuchanekileyo, kunye nofakelo olusebenzayo ludibana. Umphezulu umenyezelayo yeyona ndawo incinci inomdla ngayo.
