Izixhobo ze-welding zibamba iinxalenye kwindawo ngqo-akukho ngqikelelo, akukho msebenzi kwakhona. Xa ukunyamezela kuyancipha ukuya ku-± 0.1 mm kunye namaxesha okujikeleza kufuna ukuphindaphinda kwiiyunithi ze-500 +, iijigi eziqhelekileyo ziyasilela. Kulapho I-3D ye-welding fixture Iinkqubo zingena-kungekhona njengezongezo, kodwa njengezandiso zobunjineli zenjongo ye-welder.
Kutheni "i-3D" itshintsha into enokwenziwa ziiFixtures
I-3D ye-welding fixture ayichazwanga ngenani leezembe. Ichazwa ngendlela eyisombulula ngayo imiqobo yehlabathi yokwenyani: ii-engile ezidityanisiweyo kwizibiyeli ze-chassis, iiflange ezifakwe kwindlwane kwi-hydraulic manifolds, okanye iindibano zezinto ezininzi apho ukwandiswa kwe-thermal kuhluka phakathi kwe-aluminiyam kunye nentsimbi engenasici. Siye sabona abathengi belahla i-12% yeebhetshi zokuqala ngenxa yokuba izilungiso zelifa azikwazanga ukugcina i-perpendicularity phakathi kwendlebe egobileyo kunye ne-laser-cut mounting surface. Ukulungiswa kwakungeyona i-clamps eqinile-yayiyi-layout-based layout evale amanqaku e-datum kwi-X, Y, * kunye ne-Z ngaxeshanye.
Ubuchule bokwenyani be-3D buthetha izinto ezintathu ekusebenzeni:
Iipleyiti zesiseko semodyuli ezineendawo zokubeka i-T ezichanekileyo kunye neendawo eziphindaphindwayo ze-dowel pin (±0.01 mm) Iindawo ezitshintshayo-hayi nje izikhonkwane kunye nokumisa, kodwa zixhasa ukuphakama-uhlengahlengiso, iibhloko zendlwane e-angular, kunye neengalo ezibambezelayo ezikhawulezayo zokutshintsha nokugcinwa kwetorque. Ijiyometri yesalathiso esidityanisiweyo, ke yonke indawo indlwane ngokuchasene nenqwelomoya efanayo, hayi ngokuchasene nomda ongahambelaniyo welinye icala. Oku akuyothiyori. Kwiprojekthi yezixhobo zezolimo enye, ukutshintsha ukusuka kwi-2D ukuya kwisiko le-3D kunqumle ukugqwetheka kwe-weld ngama-63% kwaye kuncitshiswe ixesha lolungiso lwasemva kwe-weld ukusuka kwimizuzu eyi-18 ukuya ngaphantsi kwemizuzwana engama-90 kwi-subassembly nganye.
Yintoni eyenza iFixture Ilingane—Hayi nje Ukubamba
Abanye abavelisi baphatha izixhobo njengetemplates ezimileyo. Sibaphatha njengabancedisi benkqubo. Isixhobo kufuneka siphile kwimijikelo engama-5,000+ ngaphandle kokuphulukana nentembeko yendawo. Kufuneka ivumele ukufikelela kwiitotshi ze-MIG, iintloko ze-robotic welding, kunye nokuhlolwa kwe-post-weld-ngaphandle kokufuna ukuchithwa. Kwaye kufuneka isikali: isiseko seplate efanayo, iindawo ezahlukeneyo, kwiprototype eqhuba iiyunithi ezili-15 kunye neebhetshi zokuvelisa ze-3,000.
Sifumene izinto ezintathu ezingaxoxiswana ngexesha lokusasazwa:
Uzinzo lwezinto: Akukho ziseko zentsimbi ezijikajikayo emva kokuphinda ibhayisekile ye-thermal. Sisebenzisa i-42CrMo4 intsimbi ye-alloy ehlanjululweyo okanye i-anodized 7075-T6 i-aluminium-ivavanyelwe i-dimensional drift kwi-80 ° C ngaphezu kweeyure ezingama-72. Ukuhambelana kwamandla obambe: I-Spring-loaded clamps ilahlekelwa ukubamba; ezomoya zifuna imigca yomoya. Umgangatho wethu usebenzisa intsimbi eqinileyo yokuguqula intsimbi enesitshixo esiqinisekileyo somatshini-engqinwe kwi-12 kN yokubamba amandla, ephindaphindwayo ngaphakathi ± 3% Ukuba nenkonzo: Ababonisi bayanxiba. Izikhonkwane ziyaqatywa. Ke yonke into ye-3D ye-welding ibandakanya ukufakwa okunokutshintshwa okuqinileyo-kungekhona iimpawu zoomatshini-kunye ne-BOM epheleleyo enamaxesha okukhokela phantsi kweeyure ezingama-72. Omnye umthengisi weemoto kwiNqanaba eli-1 laseMntla waseMelika usikhabile isindululo sethu sokuqala kuba umcwangcisi wabo wendlela yerobhothi ufuna i-TCP echanekileyo. Sifake ezo zinto zihlanjululweyo ngokuthe ngqo kwimodeli ye-CAD-enikezelwe njengeefayile ze-STEP ezine-callouts ye-GD & T ehambelana nenkqubo yokulungelelanisa yomlawuli we-robot. Baqhube ukuqinisekiswa kweqhekeza lokuqala kwiiyure ze-4.2.
Iqala Njani Ukuchaneka Phambi KweWeld Yokuqala
I-3D ye-welding fixture ayibuyiseli kuyilo olubi-iyayibhentsisa. Siye saphonononga imizobo yabathengi abangaphezu kwama-200 apho i-weld seams yawela imigca egobileyo, ebangela ukuqhekeka kancinci kwiindawo ezinoxinzelelo oluphezulu. Okanye apho iimfumba zokunyamezelana zenza ukuba indibano yokugqibela ingenzeki—nangona inxalenye nganye iphumelele ukuhlolwa komntu ngamnye.
Yiyo loo nto inkxaso yethu yobunjineli iqala *phambi kokwenziwa komdlalo:
Ukubekwa kwe-weld seam eqhutywa yi-DFM: Silinganisa ukuhanjiswa kwegalelo lobushushu kwaye sicebisa ukufuduswa komthungo ukuze kuncitshiswe ukugqwetheka-okubhalwe ngeemephu zecontour ye-thermal Uphononongo lwesicwangciso seDatum: Ngaba idatha yakho ephambili ihambelana namaziko omatshini? Ngemigca yokwahlulahlula? Ngamanqaku okuhlola e-CMM asezantsi? Senza imephu zontathu I-handoff yokulungisa ukuya kwinkqubo: Asiboneleli nje ukulungiswa, kodwa i-weld parameter sheets eqinisekisiweyo kubunzima bezinto ezifanayo, iintlobo zocingo lokuzalisa, kunye neejometri ezidityanisiweyo. Akukho "ubungakanani obufanayo-bonke". Yonke I-3D ye-welding fixture siyakha siqala ngeemfuno zenxalenye yakho yokusebenza-hayi iinombolo zethu zekhathalogu.
Iziphumo zokwenyani, hayi iBenchmarks
Kwi-Botou Haijun Metal Products Co., Ltd., sivavanya izixhobo eziphantsi komthwalo-kungekhona nje ubunzima obumileyo, kodwa isingqisho sokuvelisa esifanisiweyo. Isixhobo esilinganiswe nge-3 mm yentsimbi ethambileyo kufuneka sibambe inyani kwimijikelo eyi-100 elandelelanayo kwiqondo lobushushu le-120°C, kunye ne-3-second clamp actuation, kunye ne-15-sekondi ye-weld yokuhlala-konke kufakwe kwiigeyiji zoxinzelelo kunye ne-thermal imaging.
Abathengi bethu banika ingxelo ngeziphumo ezifanayo:
I-92% yokunciphisa ulungelelwaniso lwe-fit-up yenqaku lokuqala Ukunyanzeliswa kwexesha le-Weld cycle ye-18-27%, iqinisekiswe ngezifundo zokuhamba kwexesha Izinga le-Scrap liyehla ukusuka kwi-4.7% ukuya kwi-0.3% kwiindibano ezinzima ezine-≥7 ze-weld joints Asithengisi izixhobo. Sihambisa ukuphindaphinda-kulinganiswa kwii-microns, ezilandelwa ngemizuzu, ziqinisekiswe ngokubhaliweyo. Kuba xa imveliso yakho ishukuma, iphakamisa, okanye ithwele umthwalo, i-weld ayikho nje into edibeneyo. Sisiseko.
