Ukusetjenziswa kwe-aluminium alloy high pressure casting emkhakheni wamarobhothi ahlakaniphileko
ihlathululo1
Ukwakheka okuhlangeneko kwamarobhothi ahlakaniphileko
Amalunga wamarobhothi ahlakaniphileko, njengamalunga womzimba womuntu, aneemfuneko eziphezulu khulu zezinto ezinokutjhuguluka nokuthwala. Ikambiso yokuphosa nge-aluminium alloy ephezulu yenza bona indlu ehlangeneko igcwalise ngokunembileko i-aluminium alloy ketshezi kiwo woke amakhona amancani wesikhunta esiyinkimbinkimbi ngesikhathi senqubo yokubumba. Ukwenza isibonelo, indawo yokuhlanganiswa kwesihlakala serobhothi yamabubulo enama-axis asithandathu inebhodi elidephileko elingu-3-5mm kwaphela, kodwana lingakghona ukuthwala i-torque engu-50-100N・m, ngebanga lesakhiwo esiqinileko esinikelwe ku-high-pressure casting. Ekukhiqizeni, silawula ngokunembileko amazinga womtjhiso ku-660±5°C ukwenza bona ingxube ye-aluminiyamu ifane kuhle nesikhunta ngaphasi kwegandelelo eliphezulu le-100-150MPa, ukuqinisekisa bona ukunemba kwe-dimensional yendlu kufinyelela ku-±0.1mm begodu uburhaba bephasi Ra bulawulwa ngaphakathi kwe-1.6μm, ukubeka isisekelo sokuhlanganisa nokusebenza okuphezulu yeengcenye ezihlangeneko.
Izindlu ezinciphisako
Njengengcenye eqakathekileko yokudlulisa, ikhwalithi yendlu ye-robot reducer ithinta ngqo ukusebenza kuhle nokuzinza kokudlulisa. Indlu ye-reducer eyakhiwe nge-aluminium alloy high-pressure casting inokuzinza okuhle khulu kokutjhisa kanye nezakhiwo zomtjhini. Thatha i-harmonic reducer housing njengesibonelo. Nanyana incani ngobukhulu, inesakhiwo esiyinkimbinkimbi esinamazinyo amahle ahlanganisiweko kanye nemigodi yokufaka ngaphakathi. Ngesikhathi senqubo yokuphosa, sisebenzisa ithekhnoloji yokuklama isikhunta ethuthukileko ukulawula ukutjhuguluka kwendlu ngaphakathi kwe-0.05mm ngaphasi kokugandeleleka okuguquguqukako kwe-80-120MPa. Ngesikhathi esifanako, ngendlela ekhethekileko yokuhlanza indawo, ukujamelana nokuguga kwendlu kuyathuthukiswa, begodu ukunemba kokudlulisa kuqinisekiswa ngesikhathi sokunyakaza okubuyela emuva okuphezulu kwerobhothi, iindleko zokulondoloza ziyehliswa, ipilo yomsebenzi iyanwetshwa, begodu isiqinisekiso sokudlulisa esithembekileko sinikelwa ukunyakaza okuqondileko kwerobhothi ehlakaniphileko.
Indlu yomlawuli
Indawo yokulawula yerobhothi ehlakaniphileko akukafaneli ivikele iingcenye zangaphakathi ze-elekthronikhi ezinembileko ebhodulukweni langaphandle kwaphela, kodwana ibe nokusebenza okuhle kokukhipha umtjhiso. Indlu yomlawuli eyenziwe nge-aluminium alloy high-pressure casting ineembambo ezili-10-15 zokukhipha ukutjhisa ezisabalaliswe ngokulinganako ngobude obungu-150-200mm ngokusebenzisa umklamo wesakhiwo seembambo zokukhipha ukutjhisa, begodu isikhala silawulwa ngokunembileko ku-3-5mm. Lokha irobhothi nayikhiqiza umtjhiso ngesikhathi sokusebenza okuragela phambili, ukudlulisa ukutjhisa okuphezulu kwe-aluminium alloy (ukudlulisa ukutjhisa okungu-100-200W/(m・K)) kungadlulisela ukutjhisa msinyana ebusweni begobolondo, bese ilawula izinga lokutjhisa ngaphakathi kwebanga lokusebenza eliphephileko leengcenye ze-elekthronikhi (ngokuvamileko elingadluli i-60) ngokutjhisa phakathi kokuthintana nokutjhisa ummoya. Ngesikhathi esifanako, ukusebenza kwayo okuhle kokuvikela igezi kuvimbela ukuphazamiseka kwegezi begodu kuqinisekisa ukusebenza okuzinzileko komlawuli, okuvikeleka okuqinileko "kwengqondo" esebenzako yerobhothi ehlakaniphileko.

I-FAQ
Umbuzo 1: Ungaqinisekisa njani ukuqina kweengcenye zamarobhothi ezenziwe nge-aluminium alloy high-pressure casting ngaphasi kokusetjenziswa okuphezulu?
A1: Silawula ngokuqinileko umthombo wezinto begodu sikhetha ama-aluminium alloys wekhwalithi ephezulu ukuqinisekisa bona amandla wawo wokudonsa angafinyelela ku-250-300MPa. Ngesikhathi senqubo yokuphosa ngegandelelo eliphezulu, ukulawulwa kwepharamitha yenqubo eqondileko kwenza isakhiwo sangaphakathi sokuphosa sibe siminyene begodu kwehlise ukukhubazeka okufana nama-pores nokufakwa. Ngesikhathi esifanako, ngokusebenzisa ukuqiniswa kokutjhisa okulandelako, ukugandeleleka kwangaphakathi kuyaqedwa begodu amandla wokudinwa weengcenye athuthukiswa godu. Ekusetjenzisweni kwangempela, ngemva kokuhlolwa kokulingisa, igobolondo elihlangeneko lerobhothi lisakwazi ukugcina ukusebenza okuzinzileko ngaphasi kwemijikelezo eyi-10^7 yokulayisha, ukuhlangabezana neendingo zokusetjenziswa okuphezulu.
Q2: Ingabe ukunemba kwemilinganiso yamarobhothi anamajamo ahlangahlangeneko kungaqinisekiswa?
A2: Kuliqiniso. Sisebenzisa ithekhnoloji ethuthukisiweko yokwenza isikhunta kanye nemitjhini yokuphosa ngokunembileko. Esigabeni sokuklama isikhunta, sisebenzisa ukuhlaziywa kokulingisa kwekhomphyutha ukwenza ngcono ihlelo lokuthulula kanye nokusabalala kwezinga lokutjhisa lesikhunta. Ngesikhathi senqubo yokuphosa, i-aluminium alloy liquid igcwaliswa ngokunembileko emgodini wesikhunta ngebelo elikhulu nangokugandeleleka okukhulu ngesisetjenziswa sokujova esinembileko esiphezulu, ukwenzela bona ukunemba kobukhulu bokuphosa kufinyelele ezingeni le-IT7-IT8, begodu ukuphambuka kobukhulu beengcenye eziqakathekileko kulawulwa ngaphakathi kwe-±0.05mm, okuhlangabezana neemfuneko eziphezulu zokuhlanganiswa okuhlakaniphileko amarobhothi wokwenza izinto ezibunjwe ngendlela ehlukileko.
Umbuzo 3: Ingabe iingcenye zamarobhothi ezifakwe nge-aluminium alloy high-pressure casting zithambekele ekugqwaleni?
A3: Sineendlela zokuzivikela ezihle khulu kilokhu. Kokuthoma, khetha izinto ezihlanganisiweko ze-aluminium ezinezinto ezincani ezingcolileko ukwehlisa khulu ubungozi bokugqwala. Ngemva kokuphosa, ukuphathwa okukhethekileko kwephasi okufana nokwenza i-anodizing kuzokwenziwa ukwakha ifilimu ye-oxide eminyeneko enobukhulu obufika ku-10-25μm. Ifilimu le inokujamelana nokugqwala okuhle khulu begodu ingajamelana kuhle neendaba ezigqwalako ezifana nama-esidi, ama-alkali kanye namasawudo eendaweni zamabubulo. Ngemva kokuhlolwa kokufafaza itswayi, ama-casting aphathweko bekanganakho ukugqwala okusobala ebusweni bendawo yokufafaza itswayi yama-awa ama-500, okuqinisekisa ukusebenza okuzinzileko kwesikhathi eside kweengcenye zamarobhothi eendaweni ezimbi.
Q4: Ingabe umjikelezo wokulethwa mude weengcenye zamarobhothi we-aluminium alloy ephezulu?
A4: Sinendlela yokukhiqiza evuthiweko eyenziwe ngokwezifiso kanye nehlelo lokuphakela elisebenza kuhle. Kusukela eemfunekweni zamakhasimende ukuya ekuklameni nokukhiqizeni isikhunta, ukuya ekukhiqizweni kokulinga komkhiqizo nokukhiqiza ngobunengi, isixhumanisi ngasinye sihlobene khulu. Eengcenyeni ezenziwe ngokwezifiso zobukhulu obujayelekileko nesakhiwo, ukulethwa kungaqedwa kungakapheli amaviki ama-3-4; eencenyeni eziyinkimbinkimbi nezikulu, umjikelezo wokulethwa kwamaviki ama-6-8 kwaphela. Ngesikhathi esifanako, sizokugcina ukukhulumisana kwesikhathi sangempela namakhasimende, sinikele ngempendulo ngesikhathi ngentuthuko yokukhiqiza, begodu siqinisekise iragelophambili elilula lamaphrojekthi wamakhasimende.
Q5: Ingabe iindleko ze-aluminium alloy high-pressure casting yamarobhothi ziphezulu?
A5: Ngokombono weenzuzo zesikhathi eside, inzuzo yeendleko isobala. Nanyana iindleko zezinto ezisetjenziswako ze-aluminiyamu ziphezulu kancani kunalezo zezinye iipulasitiki zobunjiniyela, ikambiso yokuphosa ngegandelelo eliphezulu ingafinyelela ukubunjwa okuseduze, ngezinga lokusetjenziswa kwezinto ezifika ku-85% ukuya ku-95%, okwehlisa iimvumelwano zokusebenza ezilandelako. Ngesikhathi esifanako, ngesikhathi sokukhiqiza ngobunengi, iindleko zokwabelana ngesikhunta ziyancipha, begodu ukusebenza kokuphosa kuzinzile, okwehlisa iindleko zokusebenza kabutjha nokulahlwa okubangelwa ziinkinga zekhwalithi. Nayiqathaniswa neenkambo zokukhiqiza ezijayelekileko, iindleko zoke zingaphungulwa ngama-20% - 30%, okunikela amakhamphani wamarobhothi ahlakaniphileko ngeensombululo zeengcenye ezibizako.
