Umthelela Wokushisa Okulinganiselwe Ekusebenzeni Kwamapuleti E-Isothermal Roller Chain: Izindlela Eziyinhloko Zekhwalithi Wonke Umthengi Okumelwe Azazi
Embonini yokudlulisa izimboni,uchungechunge lwe-rollerUkusebenza kunquma ngqo ukusebenza kahle kwemishini kanye nokuphila kwayo kwesevisi. Njengengxenye eyinhloko, ethwala umthwalo we-roller chain, ikhwalithi ye-isothermal chain plate ibaluleke kakhulu. Ukusebenza kwe-chain plate kuhlobene eduze nenqubo yokwelapha ukushisa, kanye nokushisa kokushisa, ipharamitha eyisihluthulelo, enethonya eliqondile ezinkomba ezibalulekile njengokuqina kwe-chain, ukuqina, kanye nokumelana nokuguguleka.
1. Ubudlelwano Obuyisisekelo Phakathi Kwamapuleti E-Isothermal Chain kanye Nenqubo Yokushisa
Ama-Isothermal chain plate ayizingxenye ezibalulekile ezikhiqizwa ngenqubo ye-austempering, enikeza izinga elithile lokuqina ngenkathi igcina amandla. I-Tempering, isinyathelo sokugcina sokwelashwa kokushisa, ngokuyinhloko isusa ukucindezeleka kwangaphakathi ngemva kokucima, ilungisa isakhiwo sangaphakathi sensimbi, futhi ekugcineni inquma izakhiwo zemishini ze-chain.
Ngesikhathi senqubo yokushisa, ngisho nokushintshashintsha okuncane kwezinga lokushisa kungabangela izinguquko esakhiweni sangaphakathi se-metallurgical se-chain plate. Lapho izinga lokushisa lokushisa liphansi kakhulu, inani elikhulu lesakhiwo se-martensite esakhiwe ngesikhathi sokucima lihlala. Nakuba lokhu kugcina ubulukhuni obuphezulu, ukucindezeleka kwangaphakathi akukhululiwe ngokuphelele, okwandisa ubuthakathaka be-chain. Uma izinga lokushisa liphezulu kakhulu, i-martensite iyabola ngokweqile, inciphise kakhulu amandla nobunzima be-chain, okwenza ingakwazi ukuhlangabezana nezidingo zokuthwala umthwalo. Ngakho-ke, ukulawula okunembile kwezinga lokushisa lokushisa kuyindlela eyinhloko yokulinganisa izici zokusebenza ezahlukene ze-chain.
2. Umphumela Wokushisa Okulinganiselwe Ekuqineni Kweketanga: Ukulinganisela Amandla Nokusebenza
Ukuqina kuyisibonakaliso esiyisisekelo somthamo wokuthwala umthwalo weketanga futhi kuhlobene ngqo nekhono loketanga olugoqekayo lokumelana nokuguquguquka ngaphansi kwemithwalo ephezulu. Idatha yokuhlola ikhombisa ubudlelwano obubi obukhulu phakathi kokushisa kokushisa kanye nokuqina kweketanga.
Uma izinga lokushisa lokushisa liphakathi kuka-200°C no-300°C, ubulukhuni beketanga bungagcinwa phakathi kuka-38 no-42 HRC, ububanzi obuhlangabezana nezidingo zokuthwala umthwalo wezinhlelo zokusebenza eziningi zokudlulisa izimboni. Kuleli zinga lokushisa, izinhlayiya ze-carbide ngaphakathi kweketanga zilungile futhi zisatshalaliswe ngokulinganayo, zigcina amandla aphezulu atholakala ngemva kokucima ngenkathi futhi zisusa ezinye izingcindezi zangaphakathi ngokushisa okuphansi. Uma izinga lokushisa liphakanyiswa liye ku-350-450°C, ubulukhuni behla bufike ku-30-35 HRC. Ngenkathi amandla ehla, ukuqina kuthuthuka kakhulu, okwenza kufaneleke imishini edinga ukuqala njalo. Kodwa-ke, lapho izinga lokushisa lidlula ku-500°C, ubulukhuni behla ngaphansi kuka-25 HRC, futhi ipuleti leketanga lithambekele ekuguqulweni kwepulasitiki, okwenza lifaneleke kuphela ezimweni ezilula zokudlulisa ezinemithwalo elula kanye nesivinini esiphansi.
Abathengi kufanele bakhethe amapuleti eketanga anezinga lokushisa elifanele isilinganiso somthwalo wemishini yabo. Isibonelo, amaketanga e-roller emishini yezimayini, okumele amelane nomthelela omkhulu, kufanele aqiniswe cishe ku-250°C kumaketanga anokuqina okuphezulu. Amaketanga okushayela emigqeni yokucubungula ukudla, ngakolunye uhlangothi, angaqiniswe ku-350°C kumaketanga anokuqina okuphakathi, ukulinganisela ukuqina kanye nokumelana nokuguguleka.
3. Ukuqina Nokumelana Nokukhathala: Umthelela Ofihliwe Wokushisa Okushisayo
Ukuqina kwepuleti leketanga kunquma ukumelana kwalo nomthelela, kuyilapho ukumelana nokukhathala kunquma isikhathi sokuphila kweketanga le-roller. Nakuba kunzima ukulilinganisa ngqo, lezi zinkomba ezimbili zidlala indima ebalulekile ekusebenzeni kwesikhathi eside kwemishini futhi zombili zithinteka ukujula kokushisa kokushisa. Ukushisa okuphansi (ngaphansi kuka-200°C) kuphumela ekucindezelekeni okuphezulu okusele ngaphakathi kwepuleti leketanga, okuholela ekuqineni okunganele futhi okuvame ukuqhekeka ngaphansi kokushaywa okuphindaphindiwe. Njengoba izinga lokushisa lokushisa lenyuka laya ku-300-400°C, ukucindezeleka okusele kukhishwa kancane kancane, ukuqina kwe-ferrite matrix kuyabuya, futhi ukumelana komthelela kwepuleti leketanga kungandiswa ngaphezu kuka-30%. Kuleli zinga lokushisa, ipuleti leketanga cishe aliphuki ngaphansi kwemithwalo ephindaphindayo, okwenza lifaneleke emishinini eqala futhi imise njalo, njengemishini yokunyathela kanye nama-crane.
Ukumelana nokukhathala kufinyelela esicongweni sako uma kulinganiswa ku-400-450°C. Lolu hlu lokushisa lukhuthaza imvula efanayo ye-carbide, lwakha isakhiwo esiqinile se-bainite esivimbe ngempumelelo ukuqala nokusabalala kokukhathala. Ukuhlolwa kubonise ukuthi ama-chain plate alinganiswe ku-420°C angandisa impilo yawo yokukhathala izikhathi ezingu-2-3 uma kuqhathaniswa nemikhiqizo efanayo elinganiswe ku-200°C.
Kwimishini esebenza njalo isikhathi eside, njengemishini yokuthutha kanye nemishini yokwenza amaphepha, ukukhetha amapuleti eketanga aqiniswa cishe ku-400°C kunganciphisa kakhulu imvamisa yokulungisa. Ezimweni ezinemithwalo ephansi yomthelela, ukwandisa izinga lokushisa eliqiniswayo ngokufanele ukuze kufezwe impilo yokukhathala ende empeleni kunganciphisa izindleko zokusebenza zizonke.
4. Ukumelana Nokugqwala Nokumelana Nokugqwala: Inani Elingeziwe Lokushisa Okushisayo
Ngaphezu kwezakhiwo zemishini, ukuguguleka kweketanga kanye nokumelana nokugqwala nakho kuthinteka yizinga lokushisa, okubaluleke kakhulu ngaphansi kwezimo zokusebenza ezinzima.
Ekushiseni okushisayo okungu-300-400°C, ifilimu ye-oxide eyakhiwe ebusweni beketanga inesakhiwo esiqinile, ehlinzeka ngesivikelo esithile ekugugeni ekungcoleni kumafutha okugcoba. Ngaphezu kwalokho, amaketanga aphathwe kulolu hlu lokushisa anobulukhuni obuphakathi nendawo, anciphisa ukuguguleka kuma-roller nama-pin, futhi anciphisa ukungcola kwensimbi ngesikhathi sokudluliselwa.
Ezindaweni ezinomswakama noma ezigqwalisayo, amaketanga aqiniswa ngaphezu kuka-450°C asebenza kangcono. Amazinga okushisa aphezulu anciphisa okuqukethwe kwekhabhoni kweketanga, anciphisa amathuba okugqwala phakathi kwezinhlamvu, kuyilapho futhi ekhuthaza ukwakheka kwefilimu engasebenzi futhi athuthukise ukumelana nokugqwala. Isibonelo, emishinini yokucubungula emanzini, iketanga eliqiniswa ku-500°C linokuphila kokugqwala okuphindwe ka-1.5 kunoketanga oluqiniswa ku-300°C.
Abathengi kufanele bacabangele indawo yokusebenza ngokuphelele lapho bekhetha uchungechunge. Ezindaweni zokumba ezinothuli, uchungechunge olungagugi kakhulu oluqiniswa ku-350°C luyathandwa. Emishinini yezolimo enomswakama, uchungechunge olungagugi oluqiniswa ku-450°C noma ngaphezulu kufanele lukhethwe.
5. Umhlahlandlela Wezinqumo Zokuthenga: Indlela Yokukhetha Uchungechunge Ngokusekelwe Ekushiseni Okushisayo
Ngokusekelwe emtheleleni wokushisa okushisa ekusebenzeni kweketanga, abathengi bangakhetha ngokunembile ngokulandela lezi zinyathelo ezingezansi:
Okokuqala, nquma izidingo eziyinhloko zemishini. Uma amandla okuthwala umthwalo kuyisici esiyinhloko, njengasemishinini yensimbi, khetha uchungechunge oluqiniswa ku-250-300°C. Uma ukumelana nokukhathala kuyindaba eyinhloko, njengasemishinini yendwangu, beka phambili imikhiqizo eqiniswa ku-400-450°C.
Okwesibili, hlola indawo yokusebenza. Ezimweni zokusebenza ezomile nezihlanzekile, gxila ebulukhunini. Ezindaweni ezinomswakama nezinothuli, cabanga kokubili ukumelana nokuguguleka kanye nokumelana nokugqwala, bese ukhuphula izinga lokushisa elifanele.
Okokugcina, qinisekisa amakhono okulawula inqubo yomhlinzeki. Abahlinzeki bekhwalithi ephezulu bazohlinzeka ngemingcele yokushisa yokushisa enemininingwane kanye nemibiko yokuhlola ukusebenza ukuqinisekisa ukusebenza okuhambisanayo kuwo wonke amapuleti eketanga. Kunconywa ukukhetha umenzi ongalawula njalo izinga lokushisa lokushisa ngaphakathi kokubekezelelana kwe-±10°C ukuze agweme izingozi zekhwalithi ezibangelwa ukushintshashintsha kwenqubo.
