inkcazo1
Indlu edibeneyo echanekileyo yeerobhothi ezikrelekrele
Amalungu eerobhothi ezikrelekrele, njengeelungu zomzimba womntu, aneemfuno eziphezulu kakhulu zezinto eziguquguqukayo kunye nomthamo wokuthwala. Inkqubo yokuphosa i-aluminium alloy enoxinzelelo oluphezulu ivumela i-joint housing ukuba izalise ngokuchanekileyo ulwelo lwe-aluminium alloy kwikona nganye encinci ye-complex mold ngexesha lenkqubo yokubumba. Umzekelo, i-wrist joint housing yerobhothi yemizi-mveliso ene-axis ezintandathu inobukhulu bodonga obuyi-3-5mm kuphela, kodwa inokuthwala i-torque ye-50-100N・m, ngenxa yesakhiwo esixineneyo se-organization esinikwa yi-high-pressure casting. Kwimveliso, silawula ngokuchanekileyo ubushushu kwi-660±5℃ ukwenza i-aluminium alloy ivumelane ngokuqinileyo ne-mold phantsi koxinzelelo oluphezulu lwe-100-150MPa, siqinisekisa ukuba ukuchaneka kobukhulu be-housing kufikelela kwi-±0.1mm kunye noburhabaxa bomphezulu we-Ra kulawulwa ngaphakathi kwe-1.6μm, sibeka isiseko sokuhlanganiswa okuchanekileyo kunye nokusebenza kakuhle kwezixhobo ezidibeneyo.
Izindlu zokunciphisa
Njengenxalenye ephambili yothumelo, umgangatho wendlu yerobhothi yokunciphisa umbane uchaphazela ngokuthe ngqo ukusebenza kakuhle kothumelo kunye nokuzinza. Indlu yokunciphisa umbane eyenziwe yi-aluminium alloy high-pressure casting inozinzo oluhle kakhulu lobushushu kunye neempawu zoomatshini. Thatha indlu yokunciphisa umbane njenge-harmonic njengomzekelo. Nangona incinci ngobukhulu, inesakhiwo esintsonkothileyo esinamazinyo amancinci kunye nemingxunya yokufaka ngaphakathi. Ngexesha lenkqubo yokukhupha umbane, sisebenzisa iteknoloji yoyilo oluphambili kunye nolwe-optimization ukulawula ukuguquka kwendlu ngaphakathi kwe-0.05mm phantsi koxinzelelo olutshintshanayo lwe-80-120MPa. Kwangaxeshanye, ngenkqubo ekhethekileyo yonyango lomphezulu, ukumelana nokuguguleka kwendlu kuyaphuculwa, kwaye ukuchaneka kothumelo kuyaqinisekiswa ngexesha lokuhamba kwerobhothi rhoqo, iindleko zokugcina ziyancipha, ubomi benkonzo buyandiswa, kwaye isiqinisekiso sothumelo esithembekileyo sinikezelwa kwintshukumo echanekileyo yerobhothi ekrelekrele.
Indlu yomlawuli
Indlu yokulawula yerobhothi ekrelekrele akufuneki ikhusele kuphela izinto ze-elektroniki ezichanekileyo zangaphakathi kwindawo engaphandle, kodwa ikwafanele ibe nokusebenza kakuhle kokusasaza ubushushu. Indlu yokulawula eyenziwe nge-aluminium alloy high-pressure casting ineembambo zokusasaza ubushushu ezili-10-15 ezisasazwa ngokulinganayo kubude be-150-200mm ngoyilo lwesakhiwo sembambo zokusasaza ubushushu olulungiselelweyo, kwaye isithuba silawulwa ngokuchanekileyo kwi-3-5mm. Xa irobhothi ivelisa ubushushu ngexesha lokusebenza okuqhubekayo, ukuhanjiswa kobushushu okuphezulu kwe-aluminium alloy (ukuhanjiswa kobushushu kwe-100-200W/(m・K)) kunokudlulisa ubushushu ngokukhawuleza kumphezulu weqokobhe, kwaye emva koko kulawule ubushushu ngaphakathi koluhlu olukhuselekileyo lokusebenza lwezixhobo ze-elektroniki (ngokubanzi ezingadluli kwi-60℃) ngokudibana phakathi kweembambo zokusasaza ubushushu nomoya. Kwangaxeshanye, ukusebenza kwayo okuhle kokukhusela ubushushu be-electromagnetic kuthintela ngempumelelo ukuphazamiseka kwe-electromagnetic kwaye kuqinisekisa ukusebenza okuzinzileyo kwesilawuli, esilukhuselo oluqinileyo "lwengqondo" esebenzayo yerobhothi ekrelekrele.

FAQ
Q1: Ungaqinisekisa njani ukuba iindawo zerobhothi ezenziwe nge-aluminium alloy high-pressure casting zihlala ixesha elide phantsi kokusetyenziswa rhoqo?
A1: Silawula ngokungqongqo umthombo wezinto kwaye sikhethe ii-alloys ze-aluminium ezikumgangatho ophezulu ukuqinisekisa ukuba amandla azo okutsalwa anokufikelela kwi-250-300MPa. Ngexesha lenkqubo yokuphosa ngoxinzelelo oluphezulu, ulawulo oluchanekileyo lweparameter yenkqubo lwenza ulwakhiwo lwangaphakathi lwe-casting lube lukhuni kwaye lunciphise iziphene ezifana nee-pores kunye ne-inclusions. Kwangaxeshanye, ngokuqinisa unyango lobushushu olulandelayo, uxinzelelo lwangaphakathi luyasuswa kwaye amandla okudinwa kwamacandelo aphuculwa ngakumbi. Kwisicelo sokwenyani, emva kovavanyo lokulinganisa, igobolondo le-robot joint lisenokugcina ukusebenza okuzinzileyo phantsi kwemijikelo eyi-10^7 yokulayisha, ukuhlangabezana neemfuno zokusetyenziswa rhoqo.
Q2: Ngaba ukuchaneka kobukhulu beerobhothi ezibunjiweyo ezineemilo ezintsonkothileyo kunokuqinisekiswa?
A2: Kakade ke. Sisebenzisa iteknoloji yokuvelisa isikhunta ephucukileyo kunye nezixhobo zokuphosa ngokuchanekileyo. Kwinqanaba loyilo lwesikhunta, sisebenzisa uhlalutyo lokulinganisa lwekhompyutha ukuze siphucule inkqubo yokuthulula kunye nokusasazwa kwentsimi yobushushu besikhunta. Ngexesha lenkqubo yokuphosa, ulwelo lwe-aluminium alloy luzaliswa ngokuchanekileyo kwi-mold cavity ngesantya esiphezulu kunye noxinzelelo oluphezulu ngesixhobo sokujova esichanekileyo, ukuze ukuchaneka kobukhulu be-casting kufikelele kwinqanaba le-IT7-IT8, kwaye ukuphambuka kobukhulu beendawo ezibalulekileyo kulawulwa ngaphakathi kwe-±0.05mm, okuhlangabezana ngokupheleleyo neemfuno zokuhlanganisa ngokuchanekileyo kwe-robots ezikrelekrele ze-castings ezimile ngendlela entsonkothileyo.
Umbuzo 3: Ngaba iindawo zerobhothi eziphoswe yi-aluminium alloy high-pressure casting zisengozini yokugqwala?
A3: Sineendlela zokukhusela ezifanelekileyo koku. Okokuqala, khetha izinto ze-aluminium alloy ezinokungcola okuncinci ukunciphisa umngcipheko wokugqwala. Emva kokuphoswa, unyango olukhethekileyo lomphezulu olufana nokuphoswa luya kwenziwa ukwenza ifilimu ye-oxide exineneyo enobukhulu obufikelela kwi-10-25μm. Le filimu inokumelana nokugqwala okugqwesileyo kwaye inokumelana ngempumelelo ne-corrosive media ezifana nee-asidi, ii-alkalis kunye neetyuwa kwiindawo zoshishino. Emva kovavanyo lokutshiza ngetyuwa, ii-castings eziphathweyo azizange zibe nokugqwala okucacileyo kumphezulu kwindawo yokutshiza ngetyuwa iiyure ezingama-500, okuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwezixhobo zerobhothi kwiindawo ezinzima.
Q4: Ngaba umjikelo wokuhanjiswa ude kakhulu kwiinxalenye zerobhothi eziphoswayo ze-aluminium alloy ezilungiselelwe wena?
A4: Sinenkqubo yemveliso evunyiweyo eyenziwe ngokwezifiso kunye nenkqubo yokubonelela ngeenkonzo esebenzayo. Ukusuka kwiimfuno zabathengi ukuya kuyilo lwe-mold kunye nokuveliswa, ukuya kwimveliso yovavanyo lwemveliso kunye nemveliso enkulu, ikhonkco ngalinye liqhagamshelwe ngokusondeleyo. Kwiindawo ezenzelwe ngokwezifiso ezinobukhulu obuqhelekileyo kunye nesakhiwo, ukuhanjiswa ngokubanzi kunokugqitywa kwiiveki ezi-3-4; kwiindawo ezinzima nezinkulu, umjikelo wokuhanjiswa uhlala kwiiveki ezi-6-8 kuphela. Kwangaxeshanye, siya kugcina unxibelelwano lwangempela nabathengi, sinike ingxelo ngexesha elifanelekileyo malunga nenkqubela phambili yemveliso, kwaye siqinisekise inkqubela phambili egudileyo yeeprojekthi zabathengi.
Umbuzo 5: Ngaba ixabiso leenxalenye zerobhothi ezisebenzisa uxinzelelo oluphezulu lwe-aluminium alloy liphezulu?
A5: Ngokwembono yeenzuzo zexesha elide, inzuzo yeendleko icacile. Nangona ixabiso lezinto eziluhlaza ze-aluminium alloy liphezulu kancinci kunezinye iiplastiki zobunjineli, inkqubo yokukhupha uxinzelelo oluphezulu inokufikelela kwi-near-net molding, kunye nesantya sokusetyenziswa kwezinto ukuya kuthi ga kwi-85% - 95%, okunciphisa izibonelelo zokucubungula ezilandelayo. Kwangaxeshanye, ngexesha lokuveliswa kobuninzi, iindleko zokwabelana nge-mold ziyancitshiswa, kwaye ukusebenza kwe-cast kuzinzile, kunciphisa iindleko zokuphinda kusetyenzwe kunye ne-scratch ezibangelwa ziingxaki zomgangatho. Xa kuthelekiswa neenkqubo zemveli zokuvelisa, ixabiso lilonke lingancitshiswa nge-20% - 30%, libonelela iinkampani zerobhothi ezikrelekrele ngezisombululo zecandelo ezingabizi kakhulu.
