Uma abantu abaningi bezwa 'i-stainless steel shaft roller', bafanekisela isilinda esicwebezelayo, esingaboli. Lowo umbono oyiphutha wokuqala. Iqiniso limayelana nokuphatha okulindelekile—ukuqonda ukuthi 'i-stainless' iwumndeni, hhayi isiqinisekiso, nokuthi ukusebenzisana phakathi kwe-shaft ne-roller ngaphansi komthwalo yilapho ubunjiniyela bangempela buqala khona, noma ngokuvamile, buhluleka.
Indaba Akuyona Indaba Yonke
Sizenzakalela ku-304 noma ku-316 ngokumelana nokugqwala, impela. Kodwa ngike ngabona amarola enziwe ngo-316L amahle ehluleka ngaphambi kwesikhathi ekulayisheni okuphezulu, izinhlelo zokusebenza ezinesivinini esiphansi ngoba othile ubushaye indiva ubulukhuni nokumelana nokugqoka. Umphini wawuqinile, wenza njengefayela. Ukukhetha kuvame ukushintsha phakathi kwento efana no-440C ngenxa yokuqina kwayo okuphezulu namandla okuthwala, kanye nokusebenziseka kalula kodwa okuthambile okungu-304. Ukuhwebelana. Ulwazi lwe-QSY olunama-alloys akhethekile afana nalawo asekelwe ku-nickel ezindaweni eziyingozi kakhulu kukwenza ucabange—ngesinye isikhathi isixazululo 'serola yensimbi engagqwali' esitshalweni samakhemikhali aliyona i-stainless engcono, kodwa isistimu yezinto ezibonakalayo ehluke ngokuphelele.
Bese kuba khona ukutholakala. Akuwona wonke amabha ensimbi enziwe alinganayo. Sibe nenqwaba evela kumphakeli omusha eminyakeni embalwa edlule. Ifakwe kahle, ipholishelwe isibuko. Kodwa ngaphansi kokuhlolwa kwe-ultrasonic, ukufakwa okuncane kubonisiwe. Ngesiqephu sokuhlobisa, kuhle. Ukuze uthole i-roller emgqeni wokucubungula iphepha oqhubekayo? Iphuzu lokuphuka okungenzeka. Yingakho ulwazi oluyisisekelo lwenkampani lubalulekile. Uma umenzi wezinto ezifana ne-Qingdao Qiangsenyuan Technology Co., Ltd. ekhuluma ngeminyaka engama-30 ekulingiseni nasekukhiqizeni imishini, akuyona nje inombolo. Kuyikhodi yokuba namaketanga okunikezwa kwezinto ezihloliwe kanye nokwazi lapho ungakwazi khona futhi awukwazi ukusika amakhona.
Ukwelashwa kokushisa ukuguquguquka okuthulile. Irola ingase iguqulwe isuke kusitoko sebha esiphelele, kodwa ngaphandle komjikelezo oshisayo olungile—isixazululo sokunciphisa ingcindezi, mhlawumbe ukuqina kwemvula ebangeni elingu-17-4 PH—ukuzinza kwayo kobukhulu ngaphansi kokuhamba ngebhayisikili okushisayo kuwukugembula. Ngikhumbula ulayini wokupakisha ukudla lapho amarola 'ayekhothama' kancane kancane phakathi nezinyanga zokuhlanza isitimu nokugeza okushisayo. Icala kwakungewona umklamo; bekuyirola engumshini engu-304 entula umsele ofanelekile wokuzinza.
Ukunemba kuwumsebenzi Wenqubo
Lapha yilapho ingxenye 'ye-shaft' 'yerola ye-shaft yensimbi engenasici' iba bucayi. Isixhumi esibonakalayo. Ungaba nerola enhle, kodwa uma ukubekezelelana, ukuzungeza, nokuqedwa kwengaphezulu kungafaniswa ne-shaft, uyakhathazeka, ukuguga, nokudlidliza. Ngezicelo ezinesivinini esikhulu, sikhuluma ngokubekezelelana okuyisithukuthezi okuyingxoxo phakathi kokugaya nokucija, hhayi nje i-CNC lathe pass.
I-CNC machining ithola i-geometry kahle, kodwa isenzo sokugcina ngokuvamile sisenziwa ngesandla. Isifanisi esinekhono esifanisa shaft nerola yayo, sizizwela ukudonsa kancane, sisebenzisa umbala oluhlaza okwesibhakabhaka ukuhlola amaphethini othintana naye. Yilapho okuzenzakalelayo okuhlanzekile kushaya khona udonga. Esizeni sabo, i-tsingtaocnc.com, bafaka uhlu lwemishini ye-CNC eceleni kokutshala imali. Leyo nhlanganisela iyasho. Kusho ukuthi kungenzeka baqonde ukuthi irola ingaqala njengokusakazwa komumo oseduze-netha kumajiyometri ayinkimbinkimbi (ngokwesibonelo, ngamashaneli okupholisa angaphakathi) bese iqedelwa ukunemba kwezinga le-micron ku-CNC. Lokho kuhlanganiswa kwenqubo kuyisihluthulelo sakho kokubili ukusebenza nezindleko.
Ugibe ovamile ukucacisa ngokweqile. Akuwona wonke ama-roller adinga ukuqedwa kwesibuko se-Ra 0.2. Kuzinhlelo zokusebenza eziningi zokuthutha, indawo ejike kahle (Ra 1.6 kuya ku-3.2) enama-chamfer afanelekile ingaphezu kokwanele futhi inciphisa izindleko. Ukuthatheka ngepholishi efanelekile kwesinye isikhathi kungafihla izimpawu zamathuluzi ezingaphansi komhlaba eziba yizinto ezigxilisa ukucindezeleka. Ishidi lokucaciswa kufanele liqhutshwe umsebenzi, hhayi ubuhle.
Ukwehluleka Okunamathela Kuwe
Isifundo sami esikhumbuleka kakhulu savela ekusetshenzisweni kwasolwandle. Stainless steel shaft rollers ngesistimu yokuqondisa ikhebula. Sisebenzise i-316, imishini engenasici, ilingana kahle nokucindezela. Zagqwala ngezinyanga. Hhayi ukugqwala okuvamile, kodwa ukugqwala kokuqhekeka lapho kuhlangana khona umshini nangaphansi kwezimpawu. Amanzi amile, aphelelwe umoya-mpilo adala imvelo encane i-316 engakwazi ukuyiphatha. Ukulungisa kwakungewona umsebenzi wokwenza imishini ongcono; ibiklama kabusha i-geometry yophawu futhi icacisa i-stainless yezinga eliphezulu ene-molybdenum eyengeziwe yaleso sixhumi esibonakalayo. Kwangifundisa ukuthi ngingalokothi ngibheke ingxenye ngiyedwa.
Okunye kwaba ukwehluleka ukukhathala. Irola emshinini wokuphrinta, engaphansi kwemithwalo yethonya elijikelezayo. Ukuhlaziywa kokwehluleka kukhomba irediyasi yoshintsho ebukhali lapho irola ihlangana khona ne-flange. Isikhuphukeli sokucindezeleka sakudala. Umdwebo ububiza irediyasi engu-R2, kodwa phansi esitolo, ithuluzi lidale into esondele ku-R1.5 enophawu oluncane lwethuluzi. Lokho kuchezuka okuncane, ngaphezu kwezigidi zemijikelezo, kwakwanele. Manje, ngisadidekile mayelana nokuhlolwa kwerediyasi kanye nokwenza iphrofayela yendawo yanoma iyiphi ingxenye yomthwalo oguqukayo.
Bese kuba nephutha elilula lokuhlanganisa. Ngibone irola elihle kakhulu licekelwe phansi ngumuntu osebenzisa isando ukulicindezela kushafti, libhoboza ibhore. Noma i-inverse, ukushisa i-roller ukuze ingene ku-shaft futhi iyicime ngokungaqondile, ivale izingcindezi. Ukukhiqiza okungcono kakhulu kungahlehliswa ngemizuzu esitezi sefekthri. Abahlinzeki abahle bavame ukunikeza imiyalelo ecacile efanelekile, okuwuphawu lokuthi babone umphumela.
Ukuhlanganiswa Nezinye Izingxenye
Irola ayisebenzi yodwa. Isemdansweni onama-bearing, ama-seal, nezinto zokugcoba. Cacisa irola eliqine kakhulu kodwa libhanqe nesihlahla esithambile sethusi? Uzokhathala ngokushesha. Impahla nobulukhuni kudingeka kube isinqumo sohlelo. Kuma-bearings avaliwe, ukuphela kwendawo yejenali ye-shaft roller kanye nokubekezelelana kubaluleke kakhulu ukuvimbela ukugqokwa kwezindebe ezivaliwe.
Ukuthambisa kungenye ikani lezikelemu. Amanye amagrisi ebanga lokudla awadlali kahle ngezinsimbi ezithile ezingenasici ngaphansi kwengcindezi ephezulu. Ungathola ukucindezeleka okungaphezulu. Kuyinkinga ye-niche, kodwa kuyenzeka. Uma usebenza nomkhiqizi ophinde aphathe ama-alloys akhethekile, njenge-QSY yenza nge-cobalt ne-nickel alloys, kuphakamisa ukuthi bajwayele ukucabanga ngalezi zinkinga eziyinkimbinkimbi zokusebenzisana, hhayi nje ukwenza ingxenye ezimele.
Ukuqondanisa. Yisicefe, umbulali oyisisekelo. Ungachitha imali eshisiwe ngokunembe kakhulu insimbi engagqwali kushaft rollers, kodwa uma ama-shaft amabili abagijima kuwo engaqondakali kahle ngedigri enguhhafu, uzothola ukulayishwa konqenqema, ukuguga ngaphambi kwesikhathi, kanye nokusetshenziswa kwamandla okwandisiwe. Umkhuba ongcono kakhulu uwukubhoboza komshini kanye nobuso ngendlela efanayo ukuze uqinisekise i-perpendicularity, bese, ngokubaluleke kakhulu, uqinisekisa ukuthi isifaki sinamathuluzi nolwazi lokuqondanisa ukuhlanganiswa kokugcina.
Kusakazwa Nini, Kusetshenziswa Nini Umshini Kubha
Lolu wucingo lokwahlulela oluwumongo. Ukuze uthole i-roller elula, eqinile, umshini ovela esitokisini sebha yensimbi engagqwali ngokuvamile uqondile futhi ungabizi kakhulu. Uthola ukwakheka okuhle okusanhlamvu kanye nezakhiwo ezibikezelwayo. Kodwa ake sithi udinga irola elikhulu elinobubanzi elingenalutho ukuze unciphise inertia, noma elinenethiwekhi yangaphakathi eyinkimbinkimbi yoketshezi lokudlulisa ukushisa. Ngemuva kwalokho, isikhunta segobolondo noma ukutshala imali kuba yinketho ephoqelelayo.
Inkampani efana ne-Qiangsenyuan, enobungcweti bayo obukabili, kungenzeka isondele kulokhu ngokubuza ngevolumu yohlelo lokusebenza, izidingo zokusebenza, kanye nezindleko eziphelele. Ukutshala imali kungakhiqiza ingxenye ecishe ibe yinetha enodoti omncane wezinto ezibonakalayo zamajiyometri ayinkimbinkimbi. Lokho kusakaza okungalungile bese kwenziwa ngomshini ngokunemba ku-CNC ukuze kucaciswe izindawo ezibucayi—i-bore, i-OD, ubuso—ukuba zicaciswe. Le ndlela ye-hybrid ingaba ukonga kakhulu kunokukhipha ibha enkulu eqinile.
Ubungozi ngama-cast roller yikhwalithi ye-Foundry. I-inclusions, i-porosity, i-shrinkage cavities. Yilapho iminyaka engu-30 yokuhlangenwe nakho kokusakaza kungewona umugqa wokumaketha. Kusho ukuthi bona (noma iyiphi isizinda esinedumela elihle) banezilawuli zenqubo—isango elifanele kanye nomklamo okhuphukayo, ukulawulwa kwezinga lokushisa kwesikhunta, ukuhlolwa kwangemuva kokusakazwa njenge-X-ray noma ukungena kodayi—ukuze kuncishiswe lezo zingozi. Awuthengi nje ingxenye; uthenga ikhono labo lokuphatha inqubo enokuguquguquka kwemvelo.
Ukuyigoqa: Ingxenye, Hhayi Impahla
Ngakho, a insimbi engagqwali shaft roller akuyona nje into esesithenjini sezinto zokwakha. Yiphuzu lapho isayensi yezinto ezibonakalayo, idizayini yemishini, ukukhiqizwa okunembayo, nokufakwa okungokoqobo kuhlangana khona. Indawo ecwebezelayo iyingxenye ethakazelisa kakhulu ngakho. Inani langempela lisezinqumweni ezifihliwe: izinga lensimbi elicaciswe inhlanganisela efanele yamandla, ukumelana nokugqwala, kanye namandla okwenza izinto; umzila wokukhiqiza okhethelwe ukusebenza nomnotho; kanye nokubekezelela okusetshenziswa kuzici ezibalulekile emsebenzini.
Ukubheka iphothifoliyo yomkhiqizi, njengalena ese-Qingdao Qiangsenyuan Technology, ixoxa indaba. Ububanzi obusuka kunsimbi ewugqinsi ukuya kuma-alloys akhethekile bubonisa ukuqonda ukuthi izinto eziyisisekelo ziyicebo lokukhetha. Inhlanganisela yokusakaza kanye nemishini ye-CNC ngaphansi kophahla olulodwa iphakamisa ukuthi bathole ukusebenzisana phakathi kwefomu nokulingana kokugcina. Yilolu hlobo lombono odidiyelwe oguqula i-roller elula ukusuka endaweni engase ihluleke ibe ingxenye ethembekile, ehlala njalo emshinini. Uyeka ukufuna umphakeli nje bese uqala ukufuna umlingani othola yonke inkinga, hhayi nje umdwebo.
Ekugcineni, impumelelo ngalezi zingxenye yehlela ekubuzeni imibuzo efanele ngaphambili. Uyini umthwalo? Ijubane? Imvelo? Impilo elindelwe? Izingxenye zokukhwelana? Uma uyibhala kanjalo, imininingwane icishe izibhale yona. Iqhinga liwukukhumbula ukubuza yonke leyo mibuzo ngaphambi kokuba ucezu lokuqala lwensimbi lusikwe.
