Inqubo Yokushisa Ukwelashwa Kwama-45 Wokuqeda Insimbi Nokushisa

Ukucima nokushisa kuyindlela yokushisa kabili yokuqeda ukucima nokushisa okuphezulu, futhi inhloso yayo ukwenza ukuthi indawo yokusebenza ibe nezinto ezinhle eziphelele.

Insimbi ecinyiwe futhi evuthayo inemikhakha emibili: i-carbon eqediwe ne-tempered steel kanye ne-alloy insimbi ecinyiwe futhi evuthayo. Akunandaba ukuthi ngabe yinsimbi yensimbi noma insimbi engxubevange, okuqukethwe yikhabhoni kulawulwa ngokuqinile. Uma okuqukethwe kwekhabhoni kuphakeme kakhulu, amandla we-workpiece ngemuva kokucima nokushisa kuphezulu, kepha ukuqina akwanele. Uma okuqukethwe kwekhabhoni kuphansi kakhulu, ukuqina kuzokwanda futhi amandla azobe enganele. Ukuze uthole ukusebenza okuhle jikelele kwezingxenye ezicinyiwe nezicashile, okuqukethwe kwekhabhoni ngokuvamile kulawulwa ku-0.30 ~ 0.50%.

Lapho kucinywa futhi kufakwa ithempeli, isigaba sonke se-workpiece sidingeka ukucishwa, ukuze umsebenzi wokusebenzela athole i-microstructure ephethwe yi-martensite eqoshwe kahle yenaliti. Ngokushisa okushisa okuphezulu, kutholakala isakhiwo esincane esilawulwa yi-sorbite efanelwe. Akunakwenzeka ukuthi izimboni ezincane zenze ukuhlaziywa kwe-metallographic kusithando ngasinye, futhi ngokuvamile kwenza ukuhlolwa kobulukhuni kuphela. Lokhu kusho ukuthi ubulukhuni ngemuva kokucima kufanele bufinyelele ubunzima obucimayo bento, futhi ubulukhuni ngemuva kwe-tempering buhlolwe ngokuya ngezidingo zomdwebo.

Ukusebenza kokuphathwa kokucisha nokushisa kwento yokusebenza kufanele kwenziwe ngokuqinile ngokuya ngemibhalo yenqubo. Sinikezela ngemibono ethile yokuthi ungayisebenzisa kanjani inqubo ngenkathi isebenza.

Icinyiwe futhi yomnene yensimbi engama-45 insimbi engu-45 iyinsimbi ephakathi kwesakhiwo sekhabhoni enokusebenza okuhle okubandayo nokushisayo, izakhiwo ezinhle zomshini, intengo ephansi kanye nemithombo ebanzi, ngakho-ke isetshenziswa kabanzi. Ubuthakathaka bayo obukhulu ukuqina kwayo okuphansi, ubukhulu obukhulu bezigaba ezinqamulelayo nemisebenzi yokusebenza edingeka kakhulu.

Ukushisa okucimayo kwensimbi engu-45 ngu-A3 + (30 ~ 50) ℃. Ekusebenzeni kwangempela, umkhawulo ophezulu uthathwa ngokuvamile. Izinga lokushisa eliphakeme lokuqeda lingasheshisa ukufudumeza komsebenzi, linciphise i-surface oxidation, futhi lithuthukise ukusebenza kahle komsebenzi. Ukuze uvumelanise i-austenite yomsebenzi, kudingeka isikhathi esanele sokubamba. Uma inani langempela lesithando somlilo likhulu, isikhathi sokubamba sidinga ukunwetshwa ngokufanele. Ngaphandle kwalokho, kungahle kube nobulukhuni obanele ngenxa yokushisa okungalingani. Kodwa-ke, uma isikhathi sokubamba siside kakhulu, okusanhlamvu okujiyile kanye ne-decarburization ye-oxidative engathí sina nayo izokwenzeka, okuzothinta ikhwalithi yokuqeda. Sikholwa ukuthi uma ivolumu yesithando efakiwe ingaphezulu kokuhlinzekelwa kwemibhalo yenqubo, isikhathi sokushisa nesikhathi sokubamba sidinga ukwandiswa nge-1/5.

Ngoba 45 steel machining inokuqina okuphansi, isisombululo se-saline esingu-10% esinezinga eliphezulu lokupholisa kufanele sisetshenziswe. Ngemuva kokuthi i-workpiece ingena emanzini, kufanele icinywe, kodwa ingabandi. Uma i-workpiece ipholile emanzini anosawoti, ingase iqhekeke i-workpiece. Lokhu kubangelwa ukuguqulwa okusheshayo kwe-austenite ibe i-martensite lapho isiqeshana somsebenzi sipholiswa cishe ku-180°C. Kubangelwa ukucindezeleka kwezicubu ngokweqile.

Ngakho-ke, lapho indawo yokusebenza eqediwe ipholile ngokushesha kule ndawo yokushisa, kufanele kusetshenziswe indlela yokupholisa ehamba kancane. Njengoba ukushisa kwamanzi okuphuma kunzima ukuwalawula, kufanele kusetshenziswe ngokuhlangenwe nakho. Lapho ukuzamazama kokusebenza emanzini kuyeka, indawo yokuthengisa ingapholisa umoya (ukupholisa uwoyela kungcono). Ngaphezu kwalokho, okokusebenza kufanele kususwe kepha kungami lapho kungena emanzini, futhi kufanele kuhanjiswe njalo ngokuya ngesimo sejiyometri sendawo yokusebenza. I-tuli emaphakathi yokupholisa nomsebenzi wokuma ongaguquki uholela ekubeni nobulukhuni obungalingani, ukucindezeleka okungalingani kanye nokusonteka okukhulu noma ukuqhekeka kokwenziwa komsebenzi.

Ubulukhuni bezingxenye ezingama-45 zensimbi ezicinyiwe nezicijile ngemuva kokucinywa kufanele zifinyelele ku-HRC56 ~ 59. Ithuba lokungena kwesigaba esikhulu liphansi, kepha alikwazi ukuba ngaphansi kune-HRC48. Ngaphandle kwalokho, kusho ukuthi umsebenzi awukacinywa ngokuphelele, futhi i-sorbite noma i-ferrite ingavela esakhiweni. Inhlangano, lolu hlobo lwenhlangano lusagcinwa kumatrix ngokusebenzisa i-tempering, yehluleka ukufeza inhloso yokuqeda nokushisa.

Ekushiseni okushisa okuphezulu kwensimbi engama-45 ngemuva kokucima, izinga lokushisa lokushisa imvamisa liyi-560 ~ 600 ℃, futhi imfuneko yobulukhuni yi-HRC22 ~ 34. Ngenxa yokuthi injongo yokuqeda nokushisa ukuthola izakhiwo eziphelele, ububanzi bobunzima bukhulu kakhulu. Kodwa-ke, uma imidwebo inezidingo zobulukhuni, izinga lokushisa lokushisa kufanele lilungiswe ngokuya ngemidwebo ukuqinisekisa ubulukhuni. Isibonelo, ezinye izingxenye ze-shaft zidinga amandla aphezulu, ngakho-ke izidingo zobulukhuni ziphakeme; futhi amanye amagiya nezingxenye ze-shaft ezinokhiye bokudinga ukhiye kumele zigaywe futhi zifakwe ngemuva kokucinywa nokushisa, ngakho-ke izidingo zobulukhuni ziphansi. Mayelana nesikhathi esivuthayo nesikhathi sokubamba, kuya ngezidingo zobulukhuni nosayizi wento yokusebenza. Sikholelwa ukuthi ubulukhuni ngemuva kwe-tempering buxhomeke ekushiseni kwe-tempering, okungahlobene kangako nesikhathi se-tempering, kepha kufanele ibuyele emuva. Ngokuvamile, isikhathi sokubamba nokubamba sendawo yokusebenza ngaso sonke isikhathi singaphezu kwehora elilodwa.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Inqubo Yokushisa Ukwelashwa Kwama-45 Wokuqeda Insimbi Nokushisa

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini.
