Indlu yebhetri eyenzelwe iiBYD Commercial Vehicles yaqala ekubeni yindlela yokuyila isikhunta yaya ekuhanjisweni ngobuninzi kwiintsuku ezingama-50 kuphela—yafezekiswa ngobuchule bokulungisa nokubeka ngokuchanekileyo ukuya kuthi ga kwi-millimeter.

Kwiiworkshops zokuphosa iidayi ezinoxinzelelo oluphantsi, ngaba uhlala udibana nale ngxaki: Ukunyamezelana kokulinganisa iidayi ngokucacileyo kuwela ngaphakathi kwemigangatho yokuzoba, kodwa ukwenziwa okulandelayo kuvelisa imingxunya engekho embindini kunye nokungalingani kakuhle? Emva kokugqiba uvavanyo lweqela elincinci, umgangatho wemveliso uqala ukuguquguquka xa kuqala imveliso yobuninzi, nto leyo eyenza ukuba uzinzo lungafumaneki.

Nangona ezi ngxaki zibonakala njengeempazamo zoomatshini, unobangela wazo uhlala ukho kukungabikho kokwahlulwa okucwangcisiweyo kunye nolawulo lokuchaneka koomatshini kunye nokuchaneka kokubekwa kwakhona.

01 Ukuchaneka Kwemishini: Okungaphezulu Kokuzenza "Imishini" Ngokwayo
Ukuchaneka koomatshini kudla ngokutolikwa ngokucokisekileyo njengobuchule bezixhobo zoomatshini. ukuphoswa koxinzelelo oluphantsi, nangona kunjalo, ingena kulo lonke uthotho ukusuka kwisikhunta ukuya kwimveliso egqityiweyo.

Okokuqala kukuchaneka kokuqala komatshini wokubumba. Njenge "template eyintloko" yazo zonke izinto ezibumbayo, ubukhulu bomngxuma kunye nokugqitywa komphezulu womngxuma kumisela ngokuthe ngqo umgangatho wendalo womngxuma. Okubaluleke ngakumbi kukulawula Inkqubo yokuphosa Utshintsho oluncinci kwiiparameter ezifana nobushushu be-aluminium enyibilikisiweyo, uxinzelelo lokuzalisa, kunye nesantya kunokuchaphazela ukwakheka kwesinyithi kunye nesantya sokuncipha kokugqibela, okutshintsha ubukhulu bokwenyani be-casting.

Ingcamango eqhelekileyo ephosakeleyo kukuba kuphela zimilinganiselo zokugqibela zokubumba ekufuneka zihlangabezane neemfuno. Nangona kunjalo, ukungawunaki ulawulo lwenkqubo kukhokelela kwizakhiwo ezincinci ezingalinganiyo kunye noxinzelelo olushiyekileyo ngaphakathi kokubumba. Oku kudala iingozi ezifihlakeleyo zomatshini wokugaya olandelayo, okunokubangela ukuguquguquka emva kokucutshungulwa kunye nokuphambuka kobukhulu.

Indlela yokusebenza yokulinganisa imboni ibandakanya ukusekwa kwenkqubo yolawulo olupheleleyo olunemilinganiselo. Umzekelo, xa kusenziwa i-subframe ye-aluminium alloy edibeneyo, iChina Changan ayizange igcine kuphela ubukhulu bodonga ngaphakathi koluhlu oluchanekileyo lwe-4±0.3mm kodwa, okubaluleke ngakumbi, yalungisa inkqubo yokuthulula ngokusebenzisa i-computer simulation kwaye yalawula ngokuchanekileyo isantya se-crystallization yesinyithi esinyibilikisiweyo kwi-680°C±5°C. Oku kwaqinisekisa uzinzo olunemilinganiselo kunye nokusebenza kakuhle komatshini ovela kumthombo.

02 Ukuchaneka kokubeka kwakhona: Ilitye lembombo leMveliso yoBuninzi eZinzileyo
Ngelixa ukuchaneka komatshini kuchazwa umda ophezulu weemveliso nganye nganye, ukuchaneka kokuphinda ubeke izinto kumisela umda ophantsi wemveliso yebhetshi. Kulinganisa amandla ezixhobo, iimold, okanye izinto zokusebenza ukubuyela kwindawo efanayo ngexesha lemveliso eqhubekayo okanye imisebenzi emininzi yokucinezela.

Izinto ezibangela impembelelo yayo zinobukhulu obahlukeneyo. Kwinqanaba lezixhobo, ukuzinza kwe-hydraulic okanye koomatshini kwenkqubo yokubamba yomatshini wokuphosa idayi kunye netafile yokusebenza yesixhobo somatshini kubalulekile. Uphononongo luka-2024 lubonisa ukuba ulawulo oluqhelekileyo lwesigaba esinye kwiinkqubo zokubeka umatshini wokuphosa idayi lunokubangela ukuchaneka okuphantsi kokubeka indawo ngenxa yokungasebenzi kakuhle kwenkqubo kunye nokuguquguquka kwesimo esithile.

Kwinqanaba lenkqubo, ukufakelwa kwakhona kwesikhunta, ukwanda kobushushu kunye nokucotha, kunye nokukhethwa kwezalathiso zokufumana izinto ezidityanisiweyo kwizixhobo zichaphazela ngokuthe ngqo ukuhambelana. Umzekelo, xa kulungiswa iipateni zemingxunya kwiindawo zecompressor, iimpazamo zokubeka kwindawo yazo zihlala ziyimbangela ephambili yokungachaneki kwendawo yepateni yemingxunya.

Indlela yomenzi wepompo inika isisombululo esicwangcisiweyo. Kwiindawo zesinyithi ezifakwe i-chromium ephezulu, baseke ulawulo lwenkqubo oluqala ekupheleni ukuya ekupheleni oluquka "uyilo lwesikhunta—ukubumba—ukuphosa—ukupholisa—ukucoca." Ngokwenza ngcono iiprotokholi zolondolozo lweesikhunta kunye neebhokisi eziphambili, baphucule ngokusisiseko uzinzo lwemilinganiselo yokubeka indawo ephindaphindwayo. Olu lawulo lupheleleyo lubonakala lusebenza ngakumbi kunokulandela kuphela izixhobo zoomatshini eziphezulu.

03 Amaqhinga okuBambisana oLawulo oluchanekileyo
Ukwahlula ulawulo lokuchaneka koomatshini kunye nokuchaneka kokubekwa kwakhona linyathelo lokuqala kuphela. Ukusebenza kakuhle kuvela ekuququzeleleni nasekulawuleni kwabo i-closed-loop.

Indlela entsha "luyilo oludibeneyo lokulungisa kunye nokubeka i-machining positioning." Ukujongana neempawu ze Ukuphosa ngokuchanekileyos—imijikelo emide yokucubungula kunye nokuthambekela ekuguqukeni—ukuphucula uyilo lwesalathiso sokulungisa indawo yokuphosa kunye nesalathiso sokulungisa indawo yokuphosa kunokunciphisa kakhulu ubunzima bokulungisa kwaye ngokusisiseko kunciphise imiba yasemva koomatshini efana nokungangqinelani kwemingxunya kunye nobukhulu obungalinganiyo.

Ukudibana kwetekhnoloji kutshintsha iindlela zokulawula ngokuchanekileyo. Itekhnoloji ye-LPIC (Low Pressure Induction Casting), edibanisa i-low-Ukuphosa Uxinzelelo Ngokusebenzisa utyalo-mali, ijolise ekuphuculeni iipropati zoomatshini zezinto ezibonakalayo ngelixa iqinisekisa ukuchaneka okuphezulu kobume kunye nejometri ngokusebenzisa i-automation ephezulu kunye nokuzaliswa kwezantsi ukuya phezulu.

Ukwenziwa kwedijithali kunye nobukrelekrele kwenza "inethi yokukhusela" ukuze kuchaneke. Abavelisi abaphambili behlabathi badibanisa ukujonga ngexesha langempela, uhlalutyo lwedatha, kunye nolawulo lwe-IoT ukuze baqhubeke nokulandelela iiparameter ezifana nobushushu, ukuhamba kwesinyithi, kunye noxinzelelo, ukuqinisekisa ukuhambelana kwenkqubo.

04 Izisombululo Ezisebenzayo Zokujongana Namanqaku Entlungu
Xa ujongene nemingeni ethile yokuchaneka, sebenzisa uphuculo olujoliswe kulo ngezi ndlela ziqhelekileyo:

Okokuqala, sombulula umahluko phakathi kobukhulu emva kokwenziwa kwemishini. Ukuba izinto ezisetyenziswayo xa zithuthwa zibonisa ukuphambuka okucwangcisiweyo emva kokwenziwa kwemishini, qala uhlole kwaye ulinganise imilinganiselo yokubeka izinto ezisetyenziswa xa zithuthwa ukuze uqinisekise ukuba zihambelana noyilo lwezixhobo ezisetyenziswa xa zithuthwa kunye nemilinganiselo yokuhlolwa.

Kwangaxeshanye, hlalutya uzinzo lwemilinganiselo yenkqubo yokukhupha. Umzekelo, hlaziya ukuphoswa koxinzelelo oluphantsi bamba iirekhodi zoxinzelelo kunye negophe lokupholisa ukuze uchonge iindawo zokuguquguquka.

Okwesibini, phucula ukuhambelana kwemveliso ngobuninzi. Misela iirekhodi zempilo yesikhunta, jonga rhoqo kwaye ubhale phantsi ukuguguleka nokuqhekeka kweendawo ezibalulekileyo, kwaye usebenzise ulondolozo lokuthintela endaweni yokulungisa izinto ezibangela ukusabela.

Kwinqanaba lezixhobo, phucula amaqhinga olawulo lokubeka iinkqubo zoomatshini ababalulekileyo bokuphosa izixhobo kunye nezixhobo zoomatshini. Umzekelo, ukutshintsha ulawulo lwesiqhelo lwesigaba esinye ngeendlela zokulawula ezinamanqanaba amaninzi kunokuphucula kakhulu ukulungelelaniswa kwenkqubo nokuphazamiseka komthwalo, nto leyo enika ukusebenza okuphezulu okuguquguqukayo kunye nokuchaneka kokubeka.

Okwesithathu, jongana nemingeni kwizinto ezintsonkothileyo ezinodonga oluncinci. Kwiindawo ezinkulu nezintsonkothileyo ezinodonga oluncinci ezifana nee-subframes zezithuthi zamandla ezintsha kunye neendawo ezinkulu zebhetri, ukuthembela kuphela kumava enkqubo akwanelanga.

Uhlalutyo lokulinganisa lwe-CAE kufuneka luqaliswe kwangethuba ukuze kuphuculwe iinkqubo zamasango kunye nezisombululo zokupholisa, kuqikelelwe kwaye kulawulwe iindlela zokuguquguquka. Kuyilo lwesikhunta, utshintsho lokuncipha kobushushu kwiindawo ezahlukeneyo zobukhulu bodonga lufuna ukubalwa kwangaphambili kunye nokubuyiselwa kwemali—ngokukodwa, ukumisela amazinga okuncipha ahlukeneyo.

EVietnam, umenzi wempompo utyale imali kwinkqubo ye-17 yehlabathi yokuphosa umbane enoxinzelelo oluphantsi, ethatha indawo yokuthulula ngesandla kuxhomekeke kubuchule babasebenzi. Injongo ephambili yolu tyalo-mali kukuphelisa ukuguquguquka kwabantu, ukuqinisekisa ukuba yonke imveliso iyahlangabezana nemigangatho echanekileyo.

Njengoko indlela yobuchwepheshe itshintsha ukusuka “kulawulo lobugcisa” ukuya “kulawulo lwenkqubo” kunye “nolawulo lwenkqubo,” ukulawula ukuchaneka koomatshini kunye nokuchaneka kokubekwa kwakhona akuseyonto ibalulekileyo. Sele iyindawo ephambili emisela ukuba ishishini lingangena na kwikhonkco lobonelelo oluphezulu lwehlabathi.

Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo)
Singakuvavanya njani ngobuninzi ukuchaneka kokuphindaphinda kwe-casting yethu enoxinzelelo oluphantsi?
Sicebisa ukuba kwenziwe "uphando lwekhono lenkqubo." Velisa ubuncinci ii-castings ezingama-30 ngokulandelelana kwaye ulinganise iseti efanayo yemilinganiselo yokubeka ebalulekileyo (umz., izikhundla zemingxunya yokubhekisa, umgama womphezulu wokufaka) kumatshini wokulinganisa odibeneyo. Bala i-avareji, uluhlu, kunye nokuphambuka okuqhelekileyo kwezi ngongoma zedatha ukuze ufumane i-index yekhono lenkqubo i-CpK. Ixabiso le-CpK elizinzileyo elidlula i-1.33 lidla ngokubonisa ukuchaneka okuhle kokuphindaphinda.

Ubushushu bokubumba buchaphazela kangakanani ukuchaneka komatshini wokugaya?
