Ngenxa yokuqina okuqinile kwezinto ezihlanganisiwe zensimbi ephezulu ye-manganese ne-alloy, i-alloy engagugi enokuqina okuqinile ingaqoqwa ngaphezulu, ukuze amandla angaphezulu ezinyo lebhakede athuthuke kakhulu, ukuze kutholakale okwengeziwe. ekahle ibhakede izinyo.Ngenxa yokuthi inezimiso eziqinile enqubweni yokumelana nesomiso, ama-alloy welding we-overlay anobunzima obuphezulu kanye nokumelana okuhle kokugqoka kufanele kukhethwe endabeni.
Ngokwezifundo ezifanele, ingxubevange yensimbi ephezulu inokumelana nokuguga okuqinile kunensimbi ephezulu ye-manganese, futhi ingxube yensimbi ephezulu noma i-martensitic cast iron alloy isetshenziswa ekwenzeni amazinyo amasha ebhakede kanye nokulungisa amazinyo amabhakede amadala.Lapho kulungiswa ukwelashwa, ilangabi le-acetylene lingasikwa ngesihloko sezinyo lebhakede elidala, lishiye inkatho ethile, bese kusetshenziswa induku yokushisela yensimbi ye-austenitic manganese ukwenza ukwelashwa okuhambisanayo kwefomu lokuqala, futhi ekugcineni imboze ukwelashwa kokushisela ngaphezulu. ukuthuthukisa ukumelana nokugqokwa kwama-excavators amakhulu ezimayini.

Okokuqala, indlela yokusika
Lapho izinyo lebhakede liphendula ngedwala (i-ore) ngaphansi komthwalo omkhulu womthelela, ngakolunye uhlangothi, lithintana nedwala (i-ore) futhi likhiqiza amandla amakhulu omthelela, uma amandla okukhiqiza wezinyo lebhakede ephansi, ichopho lezinyo lebhakede likhiqiza i-deformation ethile yepulasitiki, okulula ukwenza umsele wepulasitiki.Ngakolunye uhlangothi, lapho izinyo lebhakede lifakwa edwaleni (ore), uma ubulukhuni bezinyo lebhakede buphansi kunobulukhuni betshe (ore), izinhlayiya zamatshe (insimbi) ziphushwa ebusweni betshe. izinyo lebhakede, elizokhiqiza ama-chips amade ngendlela yejika noma i-spiral, yakhe i-groove yokusika, engase ihambisane nama-micro cutting chips.I-Chip ngenxa yesenzo sokugunda kanye nenani elikhulu lokuguqulwa, ikhiqiza inani elikhulu lokushisa okucashile, ivele isondele futhi ihlelwe kahle izinyathelo zokushelela, ukwakheka kwemibimbi, ngaphezu kwalokho, ukungqubuzana kwayo nedwala (i-ore) ukukhiqiza ukushisa kwe-friction, deformation. ukushisa okucashile nokushisa okungqubuzana nomphumela ohlangene wokwenza izinga lokushisa le-chip likhuphuke kakhulu, i-recrystallization eguquguqukayo, ukuthambisa ukuthambisa, ukuguquka kwesigaba esiguqukayo, njll., shintsha ukwakheka kwangaphakathi kwe-chip, okunye futhi kuvele into yendawo yokuncibilika.
Okwesibili, indlela yokuqeda ukukhathala
Izinyo lebhakede lifakwa edwaleni (ore) ukuze libuyele, futhi umsele wokulima wepulasitiki owakhiwe phezulu uchotshozwa yizinhlayiya zamadwala endaweni ephakeme izikhathi eziningi, ezingakha itafula lensimbi lokugeleza okuningi, kanye nokuqhekeka nokuqhekeka okuphukayo. izokhiqizwa lapho ukucindezeleka kwezinyo lebhakede kudlula umkhawulo wamandla.Eyokuqala iqhekezekile ngendlela ebheke lapho kugqokwa khona, kanti enye iqhekekile noma idatshuliwe, inemigqa ebushelelezi egobile ohlangothini olungaphambili, ithambile ngemuva, nemithende egqagqene eyakhiwe ngokuwohloka kokuchoboza emaceleni.Uma idwala liyi-angular, lizogunda ungqimba lwe-deformation futhi lenze udoti, oyisicaba futhi onqenqemeni olunemiphetho emangelengele.Kukhona futhi isimo, lapho izinyo lebhakede kanye nedwala lisebenza ngokuphindaphindiwe, i-deformation yepulasitiki yezinyo lebhakede futhi ibangele umphumela wokuqina womsebenzi ophezulu, ukuze ubuso bezinyo bezinyo lebhakede bube brittle, ngaphansi komthelela oqinile wedwala, indawo yezinyo izokwakha ama-chips brittle, futhi ingaphezulu layo linemifantu eyi-radial yokujula okuhlukene.Lesi sici sokuqhekeka kwe-brittle siphinde siwumshini wokukhathala.Indlela yokwehluleka ukugqokwa ihlobene nempahla nezimo zokusebenza, ikakhulukazi okuhlanganisa ukusika, ukuxebuka kokukhathala nezinye izindlela.Ngokuvamile, indlela yokusika ibusa inqubo yokuhluleka kokugqoka kwamazinyo ebhakede, ifinyelela ngaphezu kwe-7O;Ngokukhula kokuqina kwamazinyo ebhakede, indlela yokuxebuka yokukhathala yanda kancane kancane, ibalwa ku-2O~3O;Uma ubulukhuni bento bufinyelela emkhawulweni ophezulu, i-brittleness iyanda futhi i-brittle chipping ingase ivele.Ezimweni zokusebenza ezibuswa umshini wokusika, ukuthuthukisa ubulukhuni bezinyo lebhakede kusiza ekuthuthukiseni ukumelana nokugqoka;Ngomshini wokucoca ukukhathala, impahla iyadingeka ukuze ibe nokulingana okuhle nokuqinile;Ukuqina okuphezulu, ukuqina kokuphuka okuphezulu, izinga eliphansi lokukhula kokuqhekeka kanye nokumelana nokukhathala okunomthelela omkhulu konke kunomthelela ekuthuthukiseni ukumelana nokugqokwa kwezinto.
