Xa usiva 'i-roller shaft roller', abantu abaninzi ngokukhawuleza bafanekisela i-roller ngokwayo-i-cylinder yentsimbi eqinile, mhlawumbi eneebheringi ezithile. Yimpazamo yokuqala leyo. Enyanisweni, yinkqubo. Ukusebenza kuxhomekeke kwi-synergy phakathi kwe-metallurgy ye-shaft, umphezulu we-roller ukugqiba kunye neprofayili yokuqina, kunye nokunyamezela kwendibano. Ndibone imisebenzi emininzi igxile kuphela kwi-roller OD specs, emva koko ndizibuze ukuba kutheni benxiba ngaphambi kwexesha okanye amanqaku kwiiprofayili. I-shaft, edla ngokuba yingcamango yamva, kulapho iintsilelo ezininzi ziqala khona. Asiyophini nje; licandelo elilayishwe ngamandla.
Ukukhetha izinto eziphathekayo ayingomdlalo wokuthelekelela
Kwangoko ngexesha lam ndisebenza kunye nemigca ye-rollform, sasinomcimbi ophindaphindiweyo kunye nento ethile i-roller shaft roller iseti esetyenziselwa ukwenza imijelo yentsimbi ephezulu. Iirola, ezenziwe ngentsimbi esemgangathweni ye-D2 yesixhobo, zibambe kakuhle, kodwa siye safumana ukuphambuka kweshaft. Hayi ukuphuka, ukugoba okwaneleyo ukuphosa ukunyamezela iprofayili emva kweeyure ezimbalwa zokusebenza. Ingqikelelo yayisoloko ifuna ishafti enkulu yedayamitha, eyadala i-cascade yemicimbi yohlengahlengiso lweebhloko zezindlu.
Ukulungiswa kwangempela kwavela kwinguqu yezinto eziphathekayo kwi-shaft ngokwayo. Sitshintshe ukusuka kwintsimbi ye-4140 yentsimbi ukuya kwi-alloy ye-4340 eqiniweyo, sisebenza kunye nomthengisi oqondayo ukulayishwa kokukhathala. Esi ibingesosigqibo esivela kwikhathalogu; kwavela ekuhlalutyeni iipateni zokuphuka kunye ne-micro-movement kwisihlalo sokuthwala. Iindawo ezifana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) yiba nemvelaphi yale nto. Ngaphezulu kweminyaka engama-30 yokuphosa kunye noomatshini, bafumana loo shaft yomsebenzi onzima i-shaft roller ayisositokhwe sebha esijikiweyo. Ihlala ifuna ukuba ibe yinto ekhutshiweyo ekhutshiweyo okanye echanekileyo ukuze kuqinisekiswe icala lokuhamba okuziinkozo, emva koko yenziwe ngomatshini ukuze ikwazi ukunyamezela. Umsebenzi wabo onama-alloys akhethekileyo afana ne-nickel-based alloys ifanelekile apha-ngamanye amaxesha, kwiindawo ezingqongileyo ezigqithiseleyo, kufuneka ujonge ngaphaya kwamabakala ensimbi aqhelekileyo.
Oku kukhokelela kwelinye i-nuance: ujongano. Izihlalo ezithwele i-shaft zihlala ziphantsi, kodwa i-radio yenguqu ibalulekile. Ikona ebukhali sisigxininisi soxinzelelo esilinde ukudala indawo yokuqalisa ukuqhekeka. Sifunde ukucacisa nokuhlola ezi radii ngononophelo. Yinkcukacha encinci kumzobo eyenza umahluko omkhulu kwixesha eliphakathi phakathi kokusilela.
I-Harder yi-Fallacy engcono ye-Rollers
Kukho intsomi egqubayo yokuba ukukrazula ngobulukhuni bomphezulu kwirola ukuya kubukhulu (ukuthi, 65 HRC nangaphezulu) kuya kuzisa obona bomi bude ngokuzenzekelayo. Ngumgibe oneendleko ezinkulu. Kuba iiroli zeroli, ngakumbi ezo zenza izinto ezigqunywe ngaphambili okanye eziqhotyoshelweyo (njengezinye iintsimbi ezenziwe ngamagalvanized), indawo eqine kakhulu inokuba brittle. Endaweni yokunxiba kakuhle, iyakwazi ukukrazula okanye igalele, iwonakalisa ngoko nangoko umphezulu weshiti.
Ndikhumbula iprojekthi apho sasisenza i-alloy strip ye-aluminium-bronze. Isixhobo sasiyi-gummy. Iqela lethu lokuqala leerola laqina kakhulu. Abazange banxibe; balayisha nje imathiriyeli, bechola ingxubevange phezu komhlaba baze baphinde baprinte iziphene emculweni. Isisombululo sasichanekile: sisebenzise imathiriyeli ethambileyo ethambileyo enepolishwa, ephantse yafana nesipili kunye nonyango oluthile lokunciphisa inyonyo. Izinga lokunxiba lalilawulwa ngendlela eyahlukileyo-i-lubricity kunokuba nje ubunzima obubuhlungu.
Apha kulapho ubuchule obukhethekileyo bokusebenza kunye nokugqiba bubalulekile. Inkampani efana ne-QSY, enobuchwephesha obunzulu be-CNC kunye nobuchule bokubumba i-shell mold, inokuvelisa iirola ezineendlela zokupholisa zangaphakathi ezintsonkothileyo (ezibalulekileyo kwi-high-speed run) kunye nokuthungwa komphezulu olawulwayo. Ukukwazi ukusebenza ngensimbi engenasici okanye i-cobalt-based alloys ivula iingcango zokwenziwa kwe-corrosion okanye ubushushu obuphezulu obungenakukwazi ukuphatha i-carbon steel rollers.
I-Bearing Fit: Ukunyamezela okanye Ukuqhawula
Oku kunokuba yeyona nto isebenzayo, inxalenye yomsebenzi, kodwa ukufumana i-bearing fit engalunganga kwi i-shaft roller indibano iya kuwuchitha wonke umsebenzi wakho olungileyo kwizinto eziphathekayo. Ayisiyonto nje yokucofa i-bearing kwi-shaft. Kukho ukuqwalaselwa kwe-thermal kunye nokuqwalaselwa kwendawo yomthwalo. Kumalungiselelo amiselweyo eebheringi, udinga uphazamiseko olulingeneyo olwaneleyo ukunqanda ukurhubuluza kodwa kungabi nzima kangangokuba ilayishe ngokugqithisileyo ibheringi okanye igqwethe ugqatso lwangaphakathi.
Sakha sahlanganisa ii-roller ezintsha kraca kwiishafti nento ethi incwadi yesikhokelo ifanelekile. Ngaphantsi komthwalo kunye nobushushu bokusebenza, i-shaft yanda ngokwaneleyo ukuze yenze ukukhutshwa okuncinci. Isiphumo asizange sibe yintlekele; ibiyi-vibration eqhubekayo, ephantsi-frequency ebonisa njengamaza afihlakeleyo kwimveliso eyenziwe. Kusithathe iintsuku zokuxilonga ukuphinda sibuyele kulaa ntshukumo mincinci. Ulungiso lwalutshintshela kumlinganiselo okhethiweyo osekwe kwimilinganiselo yokwenyani elinganisiweyo kwiqondo lobushushu elilawulwayo, hayi nje amaxabiso oshicilelo aqhelekileyo.
Kwizindlu ezithwalayo kwi-roller ngokwayo, ukunyamezela kuncinci ngokulinganayo. Kuqiniswe kakhulu, kwaye unomngcipheko wokubopha xa i-roller ishushu. Ukukhululeka kakhulu, kwaye ufumana umdlalo oguqulela ngokuthe ngqo kwifomu engachanekanga. Lo ngummandla womatshini ochanekileyo. Akunjalo nje malunga nokubetha inombolo; imalunga nokuhambelana kwiseti epheleleyo yeerola zomgca wamanqanaba amaninzi. Ukukwazi ukubamba ishumi (i-intshi eziyi-0.0001) ngokuthe rhoqo, njengoko unokulindela kumboneleli womatshini onamava we-CNC, akunakuxoxiswana ngawo apha.
Ukudityaniswa kunye noVavanyo lwehlabathi lokwenyani
Unokuba nezixhobo ezigqibeleleyo zomntu ngamnye-ishaft eyenziwe ngoomatshini ngokugqibeleleyo ukusuka kwi-premium alloy, irola enobulukhuni obufanelekileyo kunye nokugqiba, kunye neebheringi ezichanekileyo-kwaye usenokusilela kwenkqubo. Ukudibanisa ngundoqo. Irola ithanjiswa njani? Ngaba iyunithi epakishwe igrisi, itywinelwe ubomi (ixhaphakile kodwa inomlinganiselo wobushushu), okanye inamalungiselelo enkungu eqhubekayo yeoli? Ukhetho luyalela uyilo lwangaphakathi lwe i-roller shaft roller.
Oku sikufunde kumgca wophahla ohamba ngesantya esiphezulu. Iinkcazo zethiyori zonke bezichanekile. Kodwa ekusebenzeni, ukwakhiwa kobushushu obuvela kwi-150 yeenyawo ngomzuzu kwakukhulu kunokuba bekulindelwe. Igrisi kwiibheringi eziqhelekileyo zaphuka, zakhokelela ekugqithiseni kunye nokuhlutha. Uyilo ngokutsha lubandakanya ukucacisa iiroli ezinoyilo oluvulekileyo lokuzala kunye nokudibanisa inkqubo yenkungu yeoli esembindini kwisakhelo seroli. Iishafu ngokwazo zazifuna iipaseji zeoli ezombiweyo. Yayiyi-retrofit nightmare eyayiza kuba lula ngakumbi ukuba isicelo somthwalo wokwenyani we-thermal wawuqwalaselwe kwasekuqaleni.
Yiyo loo nto iprototyping kunye novavanyo phantsi komthwalo kungenakubuyiselwa. Umboneleli ongaboneleli nje ngecandelo kodwa unokucebisa ngokudityaniswa kwenkqubo esekwe kwisayensi yezinto eziphathekayo kunye namava okusebenza ngomatshini wongeza ixabiso elikhulu. Ngokomzekelo, ukwazi ukuba i-shell mold cast roller blank inokubonelela nge-homogeneity engcono kwiimilo ezinzima kunezo zenziwe, okanye ukuba i-alloy esekelwe kwi-nickel ixabisa iindleko zokuzinza kwayo kwe-thermal kwisicelo sakho, ivela kumashumi eminyaka kumgangatho, kungekhona nje iphepha lokuthengisa.
Uhlalutyo lokungaphumeleli njengeSixhobo sokuFunda
Ungaze ulahle into engaphumelelanga i-roller roller okanye ishafu ngaphandle kokuyisika ivuleke kuqala. Ukuhlolwa kwesidumbu yeyona mfundo igqwesileyo. Ndigcina igalari yezinto ezingaphumeleliyo kwiofisi yam. Ishaft enye ibonise i-classic fatigue crack evela kuphawu lomatshini kwindawo engabalulekanga-isifundo ekuchazeni ukugqitywa kwe-shaft yonke, hayi nje izihlalo ezithwele. Enye i-roller ibonise ipateni yokunxiba eyahlukileyo kuphela kwicala elinye, ikhomba ukungahambi kakuhle kwindawo esingakhange siyibambe ngeempawu zethu zokudayela.
Olunye ukusilela okufundisayo lubandakanya i-roller eqhekekileyo ngokujikelezayo. Ityala lokuqala lalikwiziphene eziphathekayo. Uhlalutyo lwe-Metallurgical, ebesilwenzile ilebhu yangaphandle (nangona abanye abavelisi abadibeneyo abafana ne-QSY banalo buchule bangaphakathi kwindlu benikwe imvelaphi yabo yesiseko), babonise ukuba izinto eziphathekayo zilungile. Ipateni yokuqhekeka yalatha kuxinzelelo olugqithisileyo lwehupula. Oyena nobangela? Isixokelelwano sobuchwephesha bokutshixa i-roller kwi-shaft yayisebenzisa uxinzelelo olungaphezulu kakhulu kunoluyiliweyo, ngokusisiseko idala uphazamiseko olulingana nolucinezela ngokugqithisileyo udonga lwerola. Ukulungiswa kwaba ngumlawuli wengcinezelo olula.
La mava abumba inkqubo yokucacisa ngakumbi yepragmatic. Ngoku, xa u-odola, incoko ayikho nje malunga nemilinganiselo kunye nebakala lezinto eziphathekayo. Imalunga nesicelo: imathiriyeli eyenziweyo, isantya somgca, indlela yokuthambisa, itoni elindelekileyo, kunye nomjikelo wolondolozo. Iguqula ukuthengwa kwempahla ibe ngumzamo wobunjineli obambiseneyo, yindlela ofikelela ngayo ngokwenene ukuthembeka kunye nokusebenza kakuhle kweendleko ekusebenzeni kwe-rollforming.
