Njengoko umgangatho kunye nemigangatho yokuthotyelwa kwedatha iqhubeka nokuqiniswa kulo lonke ikhonkco lokubonelela ngeemoto, abaninzi abavelisi bamacandelo bafumanisa ukuba iinkqubo ze-welding zemveli azisahlangabezani nokulindelweyo kwii-OEM zehlabathi. Umenzi wecandelo leemoto zeTier-2 eMpuma China wafunda esi sifundo ngokwakhe emva kokungaphumeleli ngokuphindaphindiweyo uphicotho lwababoneleli be-Tesla ngenxa ye-weld spatter egqithisileyo, amaxabiso omonakalo wentambo adlula i-6%, kunye nokungakwazi ukubonelela ngedatha ye-welding elandelekayo.
Ngo-2024, inkampani iphumeze isitishi sokuwelda se-Haifei esiphezulu{1}}sokusebenza ngokufanelekileyo. Emva kweenyanga nje ezintathu zohlaziyo lwenkqubo kunye nokuqinisekiswa, umthengisi ufumene i-99.8% yokuqala -isivuno sokupasa, i-100% ye-weld data traceability, kunye ne-18% yokunciphisa indleko yeyunithi ye-welding{7}}ekugqibeleni ifumene ukutyunjwa kwemveliso ekhethekileyo ngaphakathi kwekhonkco lokubonelela likaTesla.
Lo mzekelo awubonisi kuphela uphuculo lwezixhobo eziyimpumelelo, kodwa notshintsho olubanzi kwindlela iinkqubo zokuwelda zichaza ngokutsha ukhuphiswano lwababoneleli kwimveliso{0}}ephezulu yeemoto.
Imvelaphi yoShishino: Ukunyuka kweMigangatho kwi-Automotive Welding
Ngokukhula kokwamkelwa koyilo olukhaphukhaphu kunye ne-ultra-phezulu{1}}izixhobo zamandla, iimfuno zokuwelda kushishino lweemoto ziye zafuneka kakhulu. Izinto ezifana ne-1500 MPa cinezela{4}}intsimbi eqinile ibeka imida engqongqo kwigalelo lobushushu, ubushushu{5}}ubungakanani bendawo echaphazelekayo, kunye nesithuba{6}}sentsebenzo yeweld.
Amandla emveli -i-requency resistance welding idla ngokusokola ukuhlangabezana nezi mfuno, rhoqo ibangela ukucaphuka kwezinto, ilahleko yobulukhuni, okanye ukungangqinelani komgangatho. Ngokwahlukileyo, iindawo zokusebenzela zentelekelelo zangoku ezixhotyiswe ngolawulo lwamandla oluchanekileyo kunye nokujonga inkqubo ezenzekelayo inokuhambisa umgangatho we-weld ophindaphindwayo ngelixa unciphisa ukuthotywa kwesinyithi.
Iinkqubo zokuwelda ezizenzekelayo zifikelela kuqala{0}kumazinga esivuno sokupasa ngaphezulu kwe-99.5%, ngelixa iinkqubo zezandla okanye ezisezantsi{2}}zisoloko ziguquguquka ngaphantsi kwe-90%, okukhokelela kumaxabiso aphezulu okusebenza ngokutsha kunye nemingcipheko yophicotho.
UkuQhubela phambili kokuQala: UkuSombulula umXhobo{0}}Ucelomngeni lweNtsimbi eQisiweyo
Isicelo somthengi sifuna i-welding M8 nuts kwi-1500 MPa press{2}izixhobo zentsimbi eqinisiweyo. Ngenxa yobunzima obuphezulu bemathiriyeli kunye ne-ductility ephantsi, iindlela ze-welding zesiqhelo zazisa igalelo lobushushu eligqithileyo, okukhokelela kwiziphumo ze-annealing kunye nesiseko esicuthiweyo-amandla ezinto-esingahambelani{6}}nemigaqo yokusebenza kwezinto zikaTesla.
I-Haifei projection welding workstation isebenzisa iteknoloji ye-capacitor discharge welding, kunye nexesha lokukhupha malunga ne-5 ms. Oku kukhutshwa kwamandla amafutshane kakhulu -kunqanda kakhulu ubushushu, ukugcina ubushushu{3}}kwindawo echatshazelweyo ngaphantsi kwe-1.5 mm. Ukugcinwa kobunzima be-weld -kugqithise kwi-96%, eyanelisa ngokupheleleyo iimfuno zikaTesla zokushicilela{8}}iindibano zentsimbi eziqinileyo.
Lo mgangatho wolawulo uvumela abavelisi ukuba bafezekise iiwelds ezinamandla, ezingaguquguqukiyo ngelixa begcina imfezeko yomatshini yeentsimbi eziphezulu eziphezulu{0}}eziphezulu.
UkuPhumelela kweSibini: Ukufezekisa i-100% ye-Weld Quality Traceability
Kwii-OEMs zeemoto zanamhlanje, isivuno esiphezulu sodwa asisanele. I-Tesla idinga ukuba indawo nganye ye-weld ibhalwe ngokuzimeleyo, ilandelelwe, kwaye iphicotheke{1}}ukwenza ulawulo lomgangatho wedijithali lube yinto enyanzelekileyo kunenzuzo eyongeziweyo.
Inkqubo ye-Haifei ngokuqhubekayo ibamba iiparamitha ezibalulekileyo ze-welding ngexesha langempela, kubandakanywa okwangoku, i-voltage, amandla e-electrode, kunye nokumelana okuguquguqukayo. I-weld nganye idityaniswe ngokuzenzekelayo kwinombolo ye-serial yenxalenye eyodwa kwaye ifakwe kwinkqubo ye-MES yomthengi, iqinisekisa ukuqhubeka kwedatha epheleleyo.
Abaphicothi-zincwadi banokufumana kwakhona idatha ye-waveform kunye neerekhodi zeparameter kuyo nayiphi na indawo ye-weld nangaliphi na ixesha. Esi sikhundla senze ukuba umthengisi aphumelele isatifikethi se-IATF 16949 kunye noTesla kwindawo -ehambayo yophicotho-zincwadi ngaphandle kwamanyathelo okulungisa, okukhawulezisa ukuvunywa kwababoneleli.
Ngokwenyani,{0}}ixesha lokwenyani ukulandeleka kwedatha kukwavumela ukubonwa kwangoko kwenkqubo ukukhukuliseka, ukunqanda ukunxaxha komgangatho phambi kokuba kunyukele kwibhetshi{1}}iziphene zenqanaba.
UkuPhumelela kweZithathu: UPhuculo lweXesha lokuMjikelo kunye nokuNcitshiswa kweendleko
Ngaphambi kokuzenzekelayo, umgca wokuvelisa uxhomekeke kwizikhululo ze-welding manual kunye nexesha lokujikeleza malunga nemizuzwana ye-9 inxalenye nganye, efuna abaqhubi ababini kunye nokubonisa ukuguquguquka rhoqo ngenxa yezinto zabantu.
Isisombululo se-Haifei esidityanisiweyo sokutyisa okuzenzekelayo, imipu ye-welding edadayo, kunye ne-NG ({0}}engangqinelaniyo inxalenye) yokwaliwa kwindawo enye yokusebenza. Ngenxa yoko, ixesha lomjikelo lancitshiswa libe yi-3.2 imizuzwana ngenxalenye, kunye nomsebenzi omnye kuphela ofunekayo ekuhlolweni nasekubekeni iliso.
| Metric | Phambi koPhuculo | Emva koPhuculo | Uphuculo |
|---|---|---|---|
| Ixesha lomjikelo | 9.0 s/inxalenye | 3.2 s/inxalenye | ~ 64% ngokukhawuleza |
| Imfuneko yomsebenzi | 2 abaqhubi | Umsebenzisi o-1 | I-50% yokunciphisa |
| Iindleko zokuwelda | RMB 1.35 | I-RMB 1.11 | I-18% yokunciphisa |
| Ugcino lonyaka | - | >RMB 2 yezigidi | Iimpembelelo zeendleko ezibalulekileyo |
Ezi nzuzo ziguqulelwe ngokuthe ngqo kwi-output ephezulu, ukuhambelana okuphuculweyo, kunye nexabiso eliphantsi kakhulu lokwenziwa kwemveliso.
UkuPhuhliswa kweSine: Ukusasazwa ngokukhawuleza kunye neNkxaso yezobuGcisa yendawo
Ixesha-lo{1}}lokuvelisa lalingumba obalulekileyo kwiprojekthi. Ukususela ekuqinisekisweni komyalelo ukuya kukulungela imveliso epheleleyo, ukuphunyezwa okupheleleyo kwagqitywa kwiintsuku ezingama-45. IHaifei igqibezele uyilo olulungiselelweyo ngeentsuku ezisi-7, yazisa inkqubo epheleleyo phakathi kweentsuku ezingama-20, yaze yabekwa kwi{7}}iinjineli zesayithi ukuxhasa ukugunyaziswa kunye nemveliso yokulinga.
Ufakelo -, imodyuli yoxilongo olukude ivumele ngaphezulu kwe-90% yemiba yezixhobo ukuba isonjululwe kwiiyure ezingama-48, iqinisekisa imveliso ezinzileyo kunye nokunciphisa ixesha lokuphumla elingacwangciswanga.
Le ndibaniselwano yonikezelo olukhawulezayo kunye nenkonzo yasekuhlaleni inciphise kakhulu umngcipheko wokusebenza ngexesha lokunyuka{0}}.
Isiphelo: Ukusuka ku-"Ukwazi ukuWeld" ukuya "kuthobela, okulawulwayo, kunye nokuqinisekiswa"
Kwimixokelelwane yokubonelela ngemoto-ekugqibeleni, izixhobo zokuwelda ayisesiso nje isixhobo sokuvelisa{1}}sesona sixhobo sisisiseko sokuthobela umgangatho, ulawulo lwenkqubo, kunye noxanduva lwedijithali. Ukufezekisa i-weld akwanelanga. Ii-OEMs zifuna i-welds ezihambelana nemigangatho yezinto eziphathekayo, ezilawulwa ngeenkqubo eziqinisekisiweyo, kunye nokuxhaswa ngokupheleleyo ngedatha elandelekayo.
Kwabaninzi abavelisi beTier-2 kunye neTier-3, ukukhetha iinkqubo zokuwelda ezinamava eprojekthi yamazwe ngamazwe aqinisekisiweyo kunye nobuchule benkqubo enzulu kuye kwaba linyathelo elibalulekileyo lokungena kwi-ecosystem ye-Tier-1 yehlabathi.
