Yonke i-weld echanekileyo ayiqali nge-arc-kodwa nge-surface engahambiyo. A itafile yejig yokwenza ayisiyontsimbi nje emilenzeni. Liqabane elithuleyo kuyo yonke indibano ephindaphindwayo: isiseko esibamba unyamezelo luqine ngakumbi kuneefowuni zakho ze-GD&T, lufunxa ukungcangcazela ngaphambi kokuba lufiphaze ifayili, kwaye lujike isakhono somsebenzisi sibe yinkqubo engaguqukiyo.
Sijonge iivenkile ezininzi kakhulu zileqa i-weld distortion kuphela ukuqonda ukuba unobangela yayingelogalelo lobushushu-yayiyinxalenye yentshukumo ngexesha lokubamba. Kwiprojekthi enye yezixhobo zezolimo kulo nyaka uphelileyo, impazamo yokupakishwa kwezibiyeli yomthengi yaba yi-±0.8 mm kwimingxuma eli-12. Bawuphucule umpu wabo we-MIG, bongeza irhasi yokucoca, bade baqeqeshe iiwelders kwiiparameters zepulse. Ukulungiswa? Ukwenziwa ngokutsha itafile yejig yokwenza kunye nezikhonkwane zokubeka indawo, i-dowel bushings eqinile, kunye ne-zero-play toggle clamps. Ukuhluka kokugqibela kwehle ukuya ku-± 0.15 mm-ngaphakathi kwe-spec, ngaphandle kokuphinda kusebenze.
Kutheni "itafile nje" isilela phantsi komthwalo wehlabathi lokwenyani
Itafile yejig kufuneka yenze izinto ezintathu ngaxeshanye: jonga, ucinezele kwaye uphile. Akunjalo bonke.
Ukufumana indawo kuthetha ukuphinda-phinda-hayi nje ukubetha indawo enye, kodwa ukuyenza amaxesha angama-500 kwiishifti, ukuguquka kwamaqondo obushushu, kunye nokunxiba izixhobo. Sisebenzisa intsimbi yomhlaba engenastainless sibeka iindlwane ezine-±0.01 mm flatness, hayi ipleyiti yomatshini. Ukunyanzelisa kuthetha ukuthintela amadigri amathandathu enkululeko-kungekhona nje ukucinezela phantsi, kodwa ukuxhathisa ukuphakama, ukujija, kunye nokunyuka kwecala ngexesha lokwandiswa kwe-thermal. Kungenxa yoko le nto iitafile zethu zidibanisa iileyili ze-T-slot ezidityanisiweyo ezineengalo ezibambekayo ezilinganiselwe ngumthwalo-kungekhona ibholiti kwizixhobo. Ukusinda kuthetha ukubamba ulungelelwaniso emva kokudlula kwe-weld ka-3,000+, hayi nje ukusinda ekukhanyeni kokuqala. Sicinezela-sikhulula zonke iipleyiti ezisisiseko emva komatshini kwaye siqinisekise uzinzo kunye nokutshayela kweCMM ngaphambi kokusila komphezulu wokugqibela. Skimp kuyo nayiphi na enye-kwaye uhlawula kwi-scrap, ukusebenzela kwakhona, okanye ukuthumela emva kwexesha. Siye sabona abathengi bethatha indawo yeedola ezili-120 zeeseli zerobhothi ngenxa yokuba itafile yabo yejig ijijekile phantsi kwebhayisekile eshushu. Ukulungisa itafile kubiza i-7% yexabiso lerobhothi. Kwaye ihanjiswe ngeentsuku ezili-11.
Oko Kufunwa Ngoononjineli—Asiyiyo Into Ethembisa Iincwadana Ezinemifanekiso
Abanye ababoneleli badwelisa "± 0.05 mm ukuchaneka" ngaphandle kokuchaza iimeko: ubushushu begumbi? Akukho thermal soak? Kothulwa? Ukuchaneka kwehlabathi lokwenyani kuxhomekeke kwindlela itafile eziphatha ngayo xa u-welding ngo-4 ekuseni, kunye ne-ambient temps ejikeleza i-15 ° C ngobusuku.
Yiyo loo nto sakha yonke into itafile yejig yokwenza ukomelela kokusebenza:
Izinto ezisisiseko: I-ASTM A572 yeBanga lama-50 yentsimbi yolwakhiwo—hayi intsimbi ethambileyo—ifakwe ubushushu ukuya kuma-220–250 HB ubulukhuni, emva koko ukuchaneka komhlaba ukuya kwi-0.005 mm imcaba ngaphezulu kwe-2 m². Inkqubo yokuxhoma: Iintsimbi ezidityanisiweyo ze-10-mm T-slot ezinemicu yokufaka eqinileyo (62 HRC), ivavanywe ukuya kwi-12,000 N yamandla okuqinisa icandelo ngalinye likaloliwe. Ulawulo lobushushu: Iiplati ezizikhethelayo ezipholileyo zamanzi ezisetyenziselwa umjikelezo ophezulu-uvavanywa ukuya kwi-200 welds / iyure ngaphandle kokuphambuka okulinganiswayo. Ukumodareyitha: Amanqaku ojongano olusemgangathweni avumela abasebenzisi ukuba batshintshe i-locators, bongeze i-pneumatic clamps, okanye badibanise iithagethi zokulungelelaniswa kombono-konke ngaphandle kokugrumba imingxuma emitsha. Asithengisi "iitafile." Sihambisa iinkqubo zokubeka ezilinganisiweyo. Iyunithi nganye ngenqanawa enengxelo epheleleyo yeCMM ebonisa ukucaba, ukuhambelana, kunye ne-rail-to-rail perpendicularity-traceable to NIST standards.
Akukho Ubuncinci. Akukho Gueswork. Akukho Lungelelwano ekulandeleleni
Iibhetshi ezincinci akufuneki zithethe izixhobo zenqanaba lesibini. Omnye umthengisi weemoto ze-European Tier-1 udinga i-14 i-jigs yesiko-ukuqinisekiswa kweprototype kwi-bracket entsha ye-EV yebhetri. Umthengisi wabo wangaphambili ucaphule iiveki ezili-12 kwaye wayefuna iiyunithi ezingama-50 ubuncinci. Sizise iitafile ezili-14 ezihlolwe ngokupheleleyo, eziqinisekisiweyo zeCAD kwiintsuku ezili-16. Iyunithi nganye iquke amanqaku engxelo ye-DFM, iingcebiso zolandelelwano lwe-weld, kunye neterial certs ze-EN 10131 DC04 intsimbi eqengqelekayo ebandayo.
Oku kuyasebenza ngenxa yokuba amandla ethu ame nkqo-awafakwanga:
Uyilo: Iinjineli ze-GD&T zangaphakathi ziphonononga imodeli yakho ye-3D kunye nomngcipheko wokuphazamiseka kweflegi ngaphambi kokucaphula. Yakha: I-CNC yokusika i-plasma, i-robotic welding of substructures, kunye nokugqitywa kwe-face-scraped surface-konke phantsi kophahla olulodwa lwe-ISO 9001-certified. Qinisekisa: Yonke itafile ivavanywa ngokusebenzayo kunye neengxenye zemveliso kunye neeclamps zangempela-kungekhona nje ii-calipers. Inkxaso: Ukuthunyelwa kokuthunyelwa, sigcina idatha yakho ye-CMM, imephu ye-weld, kunye nokunyamezela uhlalutyo lwe-stack-up kuhlaziyo oluzayo. Akukho kuthunyelwa ngaphandle. Akukho handoffs. Hayi "siya kujonga ngemveliso." Iqela nje elinye-ukusuka kucaphulo ukuya ekugunyazisweni.
Inyathelo lakho elilandelayo ayisiyiyo enye iQuote. YiProtokholi yoQinisekiso.
Ngaphambi kokuba ungene kwelinye ilizwe itafile yejig yokwenza, buza: Ngaba iza kunye ne-curve yozinzo lwe-thermal ebhaliweyo? Ngaba unokukuqinisekisa ukuthamba kwayo phantsi komthwalo—kungekhona nje xa uphumle? Ngaba inkqubo yokufumana yenzelwe eyona ndawo imbi kakhulu yedatum-okanye ijometri efanelekileyo?
I-Botou Haijun Metal Products Co., Ltd. yakha iitafile zejig apho injongo yobunjineli idibana nenyani yomgangatho wevenkile. Sithumele ngaphezulu kwe-870 yeenkqubo ezichanekileyo zejig ukusukela ngo-2019-kubathengi baseJamani bakha ii-nacelles ze-injini yomoya, kwiifemu ze-ag-tech zase-US ezihlanganisa iifreyimu zokutshiza ezizimeleyo, kubaboneleli be-EMS baseMzantsi-mpuma abahlanganisa i-chassis yerobhothi yezonyango. Bonke babelana ngemfuno enye: ukunganyamezeli nto kwisikhundla sokukhukuliseka.
Ukuba indibano yakho elandelayo ifuna ukuphinda-phinda-hayi ithemba-qala ngenyaniso ephezulu. Qala nge itafile yejig yokwenza yenzelwe ukubamba umhlaba, weld after weld, unyaka nonyaka.
