Ukusetshenziswa kokuphonswa kwe-aluminium alloy high pressure emkhakheni wamarobhothi ahlakaniphile
incazelo1
Indlu ehlangene eqondile yamarobhothi ahlakaniphile
Amalunga amarobhothi ahlakaniphile, njengamalunga omzimba womuntu, anezidingo eziphakeme kakhulu zezinto eziguquguqukayo kanye nomthamo wokuthwala. Inqubo yokubumba nge-aluminium alloy ephezulu ivumela i-joint housing ukuthi igcwalise ngokunembile uketshezi lwe-aluminium alloy kuwo wonke amakhona amancane e-mold eyinkimbinkimbi ngesikhathi senqubo yokubumba. Isibonelo, i-wrist joint housing yerobhothi yezimboni enama-axis ayisithupha inobukhulu bodonga obungu-3-5mm kuphela, kodwa ingathwala i-torque engu-50-100N・m, ngenxa yesakhiwo sokuhlela esiqinile esinikezwa yi-high-pressure casting. Ekukhiqizeni, silawula ngokunembile izinga lokushisa ku-660±5℃ ukuze senze i-aluminium alloy ivumelane kahle ne-mold ngaphansi kwengcindezi ephezulu engu-100-150MPa, siqinisekisa ukuthi ukunemba kobukhulu be-hound kufinyelela ku-±0.1mm kanye nobunzima bomphezulu i-Ra bulawulwa ngaphakathi kwe-1.6μm, sibeka isisekelo sokuhlanganiswa okunembe kakhulu kanye nokusebenza okubushelelezi kwezingxenye zamalunga.
Izindlu zokunciphisa
Njengengxenye yokudlulisa eyinhloko, ikhwalithi yendlu yerobhothi elinciphisa ugesi ithinta ngqo ukusebenza kahle kokudlulisa kanye nokuqina. Indlu ye-reducer eyakhiwe nge-aluminium alloy high-pressure casting inokuqina okuhle kakhulu kokushisa kanye nezakhiwo zemishini. Thatha indlu ye-harmonic reducer njengesibonelo. Nakuba incane ngobukhulu, inesakhiwo esiyinkimbinkimbi esinamazinyo amancane anezimbobo zokufaka ngaphakathi. Ngesikhathi senqubo yokukhipha, sisebenzisa ubuchwepheshe obuthuthukisiwe bokuklama isikhunta kanye nokwenza ngcono ukulawula ukuguquguquka kwendlu ngaphakathi kwe-0.05mm ngaphansi kokucindezeleka okushintshanayo okungu-80-120MPa. Ngesikhathi esifanayo, ngenqubo ekhethekile yokwelapha ubuso, ukumelana nokuguguleka kwendlu kuyathuthukiswa, futhi ukunemba kokudlulisela kuqinisekiswa ngesikhathi sokunyakaza okuphezulu okuphindaphindayo kwerobhothi, izindleko zokulungisa ziyancishiswa, impilo yesevisi iyandiswa, futhi isiqinisekiso sokudlulisa esithembekile sinikezwa sokunyakaza okunembile kwerobhothi elihlakaniphile.
Izindlu zokulawula
Indlu yokulawula yerobhothi ehlakaniphile akumele ivikele kuphela izingxenye ze-elekthronikhi ezinembile zangaphakathi endaweni yangaphandle, kodwa futhi ibe nokusebenza okuhle kokushabalalisa ukushisa. Indlu yokulawula eyenziwe nge-aluminium alloy high-pressure casting inezimbambo zokushabalalisa ukushisa eziyi-10-15 ezisatshalaliswa ngokulinganayo kubude obuyi-150-200mm ngomklamo wesakhiwo sezimbambo zokushabalalisa ukushisa olungiselelwe kahle, futhi isikhala silawulwa ngokunembile ku-3-5mm. Lapho irobhothi likhiqiza ukushisa ngesikhathi sokusebenza okuqhubekayo, ukushabalalisa ukushisa okuphezulu kwe-aluminium alloy (ukushabalalisa ukushisa okungu-100-200W/(m・K)) kungadlulisela ukushisa ngokushesha ebusweni begobolondo, bese kulawula izinga lokushisa ngaphakathi kobubanzi bokusebenza obuphephile bezingxenye ze-elekthronikhi (ngokuvamile okungadluli ku-60℃) ngokuxhumana phakathi kwezimbambo zokushabalalisa ukushisa nomoya. Ngesikhathi esifanayo, ukusebenza kwayo okuhle kokuvikela kagesi kuvimbela ngempumelelo ukuphazamiseka kwe-elekthronikhi futhi kuqinisekisa ukusebenza okuzinzile kwesilawuli, okuyisivikelo esiqinile "sobuchopho" obusebenzayo berobhothi ehlakaniphile.

Imibuzo Evame Ukubuzwa
Q1: Ungaqinisekisa kanjani ukuqina kwezingxenye zerobhothi ezenziwe nge-aluminium alloy high-pressure casting ngaphansi kokusetshenziswa kwemvamisa ephezulu?
A1: Silawula ngokuqinile umthombo wezinto zokwakha futhi sikhetha ama-alloy e-aluminium asezingeni eliphezulu ukuqinisekisa ukuthi amandla awo okubamba angafinyelela ku-250-300MPa. Ngesikhathi senqubo yokuphonsa ngomfutho ophezulu, ukulawulwa kwepharamitha yenqubo enembile kwenza isakhiwo sangaphakathi sokuphonsa sibe sikhulu futhi kunciphisa amaphutha afana nama-pores kanye nokufakwa. Ngesikhathi esifanayo, ngokuqinisa ukwelashwa kokushisa okulandelayo, ukucindezeleka kwangaphakathi kuyasuswa futhi amandla okukhathala kwezingxenye athuthukiswa kakhulu. Ekusetshenzisweni kwangempela, ngemuva kokuhlolwa kokulingisa, igobolondo le-robot joint lisengagcina ukusebenza okuzinzile ngaphansi kwemijikelezo engu-10^7 yokulayisha, ukuhlangabezana nezidingo zokusetshenziswa ngesivinini esiphezulu.
Q2: Ingabe ukunemba kobukhulu bokubumba kwamarobhothi anezimo eziyinkimbinkimbi kungaqinisekiswa?
A2: Yebo. Sisebenzisa ubuchwepheshe obuthuthukisiwe bokukhiqiza isikhunta kanye nemishini yokusika ngokunemba. Esigabeni sokuklama isikhunta, sisebenzisa ukuhlaziywa kokulingisa kwekhompyutha ukuze senze ngcono uhlelo lokuthulula kanye nokusatshalaliswa kwensimu yokushisa kwesikhunta. Ngesikhathi senqubo yokusika, uketshezi lwe-aluminium alloy lugcwaliswa ngokunembile emgodini wesikhunta ngesivinini esikhulu kanye nokucindezela okuphezulu ngedivayisi yokujova enembile kakhulu, ukuze ukunemba kobukhulu bokuphonsa kufinyelele ezingeni le-IT7-IT8, futhi ukuphambuka kobukhulu bezingxenye ezibalulekile kulawulwa ngaphakathi kwe-±0.05mm, okuhlangabezana ngokugcwele nezidingo zokuhlanganiswa okunembile kakhulu zamarobhothi ahlakaniphile okusika okunesimo esiyinkimbinkimbi.
Q3: Ingabe izingxenye zerobhothi eziphonswe nge-aluminium alloy high-pressure casting zisengozini yokugqwala?
A3: Sinezindlela zokuvikela eziphelele zalokhu. Okokuqala, khetha izinto ze-aluminium alloy ezinokungcola okuncane ukuze unciphise kakhulu ingozi yokugqwala. Ngemva kokuphonswa, ukwelashwa okukhethekile kwendawo okufana nokuphonswa kwe-anodizing kuzokwenziwa ukuze kwakhiwe ifilimu ye-oxide ende enobukhulu obufika ku-10-25μm. Le filimu inokumelana okuhle kakhulu nokugqwala futhi ingamelana ngempumelelo nemidiya egqwala njenge-asidi, ama-alkali kanye nosawoti ezindaweni zezimboni. Ngemva kokuhlolwa kokuphonswa kukasawoti, ukuphonswa okuphathwe kahle kwakungenakho ukugqwala okusobala ebusweni endaweni yokuphonswa kukasawoti yamahora angu-500, okuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwezingxenye zerobhothi ezindaweni ezinzima.
Q4: Ingabe umjikelezo wokulethwa ubude bezingxenye zerobhothi ezisebenzisa umfutho ophezulu we-aluminium alloy ezenziwe ngokwezifiso?
A4: Sinenqubo yokukhiqiza eyenziwe ngokwezifiso evuthiwe kanye nohlelo lokunikezela olusebenzayo. Kusukela ezidingweni zamakhasimende kuya ekwakhiweni nasekukhiqizweni kwesikhunta, kuya ekukhiqizweni kwesilingo somkhiqizo kanye nokukhiqizwa ngobuningi, isixhumanisi ngasinye sixhumene eduze. Ezingxenyeni ezenziwe ngokwezifiso zobukhulu nesakhiwo esivamile, ukulethwa ngokuvamile kungaqedwa zingakapheli amasonto ama-3-4; ezingxenyeni eziyinkimbinkimbi nezinkulu, umjikelezo wokulethwa ungamasonto ayi-6-8 kuphela. Ngesikhathi esifanayo, sizogcina ukuxhumana kwangempela namakhasimende, sinikeze impendulo ngesikhathi ngenqubekela phambili yokukhiqiza, futhi siqinisekise inqubekela phambili ebushelelezi yamaphrojekthi amakhasimende.
Q5: Ingabe izindleko zezingxenye zerobhothi ezisebenzisa umfutho ophezulu we-aluminium alloy ziphezulu?
A5: Ngokombono wezinzuzo zesikhathi eside, inzuzo yezindleko isobala. Nakuba izindleko zezinto zokusetshenziswa ze-aluminium alloy ziphakeme kancane kunezinye zepulasitiki zobunjiniyela, inqubo yokukhipha ingcindezi ephezulu ingafinyelela ukubumba okuseduze, ngesilinganiso sokusetshenziswa kwezinto ezifika ku-85% - 95%, kunciphisa izibonelelo zokucubungula ezilandelayo. Ngesikhathi esifanayo, ngesikhathi sokukhiqizwa kwesisindo, izindleko zokwabelana ngesikhunta ziyancishiswa, futhi ukusebenza kokukhipha kuzinzile, kunciphisa izindleko zokuvuselela kanye nezinsalela ezibangelwa izinkinga zekhwalithi. Uma kuqhathaniswa nezinqubo zokukhiqiza zendabuko, izindleko zizonke zingancishiswa ngo-20% - 30%, kunikeze izinkampani zamarobhothi ezihlakaniphile izixazululo zezingxenye ezingabizi kakhulu.
