Imishini yokushisela ibamba izingxenye ngendlela eqondile—akukho ukuqagela, akukho kusekwe kabusha. Lapho ukubekezelelana kuncipha kufika ku-±0.1 mm futhi izikhathi zomjikelezo zidinga ukuphindaphinda kuwo wonke amayunithi angu-500+, ama-jigs avamile ayahluleka. Kulapho I-3D welding fixture amasistimu ayangena-hhayi njengezengezo, kodwa njengezandiso ezinjiniyela zenhloso yomshiseli.
Kungani i-"3D" ishintsha lokho okungenziwa yi-Fixtures
I-3D welding fixture ayichazwa ngenombolo yayo yezimbazo. Kuchazwa ngendlela exazulula ngayo izingqinamba zomhlaba wangempela: ama-engeli ahlanganisiwe kubakaki be-chassis, ama-flanges afakwe esidlekeni kuma-hydraulic manifolds, noma ama-multi-material assemblies lapho ukunwetshwa kwe-thermal kuhluka phakathi kwe-aluminium nensimbi engagqwali. Sibone amakhasimende elahla u-12% wamaqoqwana aqalwe okokuqala ngenxa yokuthi ukulungiswa kwefa akukwazanga ukugcina i-perpendicularity phakathi kwendlebe egotshweyo egotshwayo nendawo ekhwezwayo esikwe nge-laser. Ukulungisa kwakungewona ama-clamp aqinile—kwakuyisakhiwo esisekelwe ekuxhumaneni esikhiya amaphuzu edatha ku-X, Y, *kanye* no-Z kanyekanye.
Amandla e-3D eqiniso asho izinto ezintathu ekusebenzeni:
Amapuleti esisekelo se-modular enezikhala ze-T ezinembayo kanye nezindawo zephini le-dowel eziphindaphindekayo (±0.01 mm) Izindawo ezishintshayo-hhayi nje izikhonkwane nezitobhi, kodwa izisekelo eziguquguqukayo ukuphakama, amabhulokhi angama-angular nest, nezingalo ezibambayo ezishintsha ngokushesha ezinokugcinwa kwetorque elinganiselwe I-geometry yereferensi ehlanganisiwe, ngakho zonke izingxenye zihlala ngokumelene nendiza yedatha efanayo, hhayi ngokumelene nonqenqema lwenye ingxenye Lokhu akulona ithiyori. Kuphrojekthi yemishini yezolimo eyodwa, ukushintsha kusuka kumathuluzi e-2D kuye kweyenziwe ngokwezifiso ye-3D kusika ukuhlanekezela kwe-weld ngo-63% futhi kwanciphisa isikhathi sokulungisa ngemva kokushisela sisuka emizuzwini engu-18 siye ngaphansi kwamasekhondi angu-90 i-subassembly ngayinye.
Yini Eyenza I-Fixture Ilingane—Ungamane Ubambe
Abanye abakhiqizi baphatha izifanekiso njengezifanekiso ezimile. Siwaphatha njengezinikezi zenqubo ezinamandla. Isakhiwo kufanele sisinde emijikelezweni engu-5,000+ ngaphandle kokulahlekelwa ubuqotho bendawo. Kufanele ivumele ukufinyelela kwamathoshi e-MIG, amakhanda okushisela amarobhothi, nokuhlolwa kwangemuva kokushisela—ngaphandle kokudinga ukuhlakazwa. Futhi kufanele ikale: i-base plate efanayo, izikhonzi ezihlukene, ku-prototype egijima amayunithi angu-15 namaqoqo okukhiqiza angu-3,000.
Sithole izinto ezintathu okungaxoxiswana ngazo phakathi nokuthunyelwa kwangempela:
Ukuzinza kwezinto: Azikho izisekelo zensimbi ezijikajikayo ngemva kokuhamba ngebhayisikili okushisayo okuphindaphindiwe. Sisebenzisa i-42CrMo4 alloy ekhululwe ukucindezeleka noma i-aluminium anodized 7075-T6—ihlolelwe ukukhukhuleka kobukhulu ngo-80°C ngaphezu kwamahora angu-72. Ukuvumelana kwe-clamp force: Ama-clamps alayishwe entwasahlobo alahlekelwa ukubamba; ezomoya zidinga imigqa yomoya. Izinga lethu lisebenzisa izinsimbi zokuguqula zensimbi eziqinile ezinokhiye omuhle—oqinisekiswe ngamandla okubamba angu-12 kN, okuphindaphindwayo phakathi kuka-±3% Ukusebenza kahle: Izindawo ziyagqoka. Izikhonkwane ziyashaywa. Ngakho-ke yonke into ye-3D yokushisela ifaka okufakwe esikhundleni okuqinile—hhayi izici ezenziwe ngomshini—kanye ne-BOM egcwele enezikhathi zokuhola ezingaphansi kwamahora angu-72. Omunye umhlinzeki wezimoto we-North American Tier-1 usenqabile isiphakamiso sethu sokuqala ngoba umhleli wabo wendlela yerobhothi ubedinga ukukhishwa okuqondile kwe-TCP. Sishumeke lokho kususwa ngokuqondile kumodeli ye-CAD yesimo—alethwe njengamafayela e-STEP anama-callout e-GD&T aqondaniswe nesistimu yokuxhumanisa yesilawuli sawo. Basebenzise ukuqinisekiswa kwesiqephu sokuqala emahoreni angu-4.2.
Ukunemba Kuqala Kanjani Ngaphambi Kokushisela Kokuqala
Ukulungiswa kokushisela kwe-3D akunxeshezeli ukwakheka okubi—kuyakuveza. Sibuyekeze imidwebo yamakhasimende engaphezu kuka-200 lapho ama-weld seam ewela imigqa egobile, okubangela ukuqhekeka okuncane ezindaweni ezinokucindezeleka okukhulu. Noma lapho izitaki zokubekezelelana zenza ukuhlangana kokugcina kungenzeki—yize ingxenye ngayinye iphumelele ukuhlolwa komuntu ngamunye.
Kungakho usekelo lwethu lobunjiniyela luqala *ngaphambi* kokwenziwa kwemidlalo:
Ukubekwa komthungo we-weld oqhutshwa yi-DFM: Silingisa ukusabalalisa okokufaka kokushisa futhi siphakamise ukuthuthwa komthungo ukuze kuncishiswe ukuhlanekezela—okubhalwe ngamamephu wekhonsathi eshisayo Ukubuyekezwa kwecebo le-Datum: Ingabe i-datum yakho eyinhloko ihambisana nezikhungo zomshini? Ngemigqa yokuhlukanisa? Ngamaphoyinti okuhlola e-CMM angezansi? Senza imephu sobathathu Ukunikezwa kokulungiswa kokucubungula: Asihlinzeki nje ngokulungiswa, kodwa amashidi epharamitha yokushisela aqinisekiswa ngokuqina kwempahla efanayo, izinhlobo zezintambo zokugcwalisa, namajiyometri ahlangene. Awekho amakhithi “alingana-owodwa”. Njalo I-3D welding fixture esakhayo siqala ngezimfuneko zokusebenza zengxenye yakho—hhayi izinombolo zekhathalogi yethu.
Imiphumela Yangempela, Hhayi Izilinganiso
E-Botou Haijun Metal Products Co., Ltd., sihlola izinto ezilungiswayo ngaphansi komthwalo—hhayi nje isisindo esimile, kodwa isigqi sokukhiqiza esilingiswayo. Isakhiwo esilinganiselwe ngensimbi emnene engu-3 mm kufanele ibambe iqiniso emijikelezweni engu-100 elandelanayo ku-120°C izinga lokushisa le-ambient, kanye ne-actuation ye-clamp yamasekhondi angu-3, kanye nendawo yokuhlala ye-weld yamasekhondi angu-15-konke kufakwe ngamageji e-strain ashumekiwe kanye nesithombe esishisayo.
Amakhasimende ethu abika imiphumela engaguquki:
Ukwehliswa okungama-92% ekulungisweni kokufaneleka kwe-athikili yokuqala Ukucindezelwa kwesikhathi somjikelezo we-Weld okungu-18–27%, kuqinisekiswe izifundo zokunyakaza kwesikhathi Izinga le-Scrap lehla lisuka ku-4.7% laya ku-0.3% emibuthanweni eyinkimbinkimbi enamajoyinti okushisela angu-≥7 Asizithengisi izinto. Siletha ukuphindaphinda-kukalwa ngama-microns, alandelelwa ngamaminithi, aqinisekiswa ngokubhaliwe. Ngoba lapho umkhiqizo wakho uhamba, uphakamisa, noma uthwala umthwalo, i-weld ayiyona nje into ehlangene. Kuyisisekelo.
