I-Welding ngaphandle kwe-jig okanye i-fixture ifana nokudibanisa ifenitshala ngaphandle kwencwadana yomyalelo-inokwenzeka, kodwa iyingozi, ayihambelani, kwaye ayifane iphindwe. Kumxube ophezulu, imveliso yevolumu ephantsi ukuya kwephakathi-ingakumbi kwizibiyeli zeemoto, amacandelo onxibelelwano lwezolimo, okanye izixhobo zokwakha izindlu-ijig kunye ne-fixture welding ayikhethi. Ngumqolo wozinzo lwe-dimensional, ukuphindaphinda kwe-weld, kunye nokhuseleko lomsebenzisi.
Sibone abathengi abaninzi kakhulu bethumela iinxalenye zenqaku lokuqala kuphela ukufumana i-0.3 mm yokungahambi kakuhle kwimingxunya enyukayo emva kokuphazamiseka kwe-thermal. Abanye baphinde basebenze kwakhona i-18% yeendibano ezidityanisiweyo ngenxa yokutshintsha kwenxalenye ngexesha lokupasa kweMIG. Le ayiyo "imiba yenkqubo." Ngabo izithuba zokulungisa. E-Botou Haijun Metal Products Co., Ltd., siyayila, siqinisekise, kwaye sisebenzise izixhobo ze-welding zesiko kungekhona njengezongezo-kodwa njengezandiso ezidibeneyo ze-weld cell ngokwayo.
Kutheni i-Off-the-Shelf Fixtures ingaphumeleli phantsi kweMityalo yoMveliso yokwenyani
Ukulungiswa kweemodyuli eziqhelekileyo kusebenza kwiiprototypes. Kodwa iijigs zomhlaba wokwenyani kufuneka ziphile kwimijikelo engama-5,000+, zixhathise ukwakhiwa kwe-spatter, zifunxe ukungcangcazela kwiitotshi zerobhothi, kwaye zigcine ± 0.15 mm ukuphindaphindwa kuzo zonke iishifti. Sakhe saphicotha umboneleli we-Tier-2 osixhobo sakhe “sehlabathi liphela” sisebenzise izibane ezilayishwe entwasahlobo. Emva kwemijikelo engama-472, amandla okubamba ehle ngama-33%. Ukungena kwe-weld kwahluka ngama-22%. Oyena nobangela? Akukho mbuyekezo yokwandiswa kwe-thermal kwi-base plate material.
Yinyani ijig kunye ne-fixture welding izisombululo zifuna ulwazi ngesinyithi-hayi nje uyilo lomatshini. Iziseko zentsimbi ezibandayo ziqengqeleka phantsi kobushushu bendawo; ii-subplates ze-aluminium zanda ngokukhawuleza kunezixhobo zokusebenza ezingenasici; nkqu ulandelelwano torque bolt kuchaphazela inxalenye ukuchaneka indlwane. Iinjineli zethu zibala i-thermal drift coefficients ngaphambi kokusika ipleyiti yokuqala. Kungenxa yoko yonke le nto siyenzayo ibandakanya:
Izinto ezisisiseko ezizinzile ngokwe-Thermally (ASTM A572 Gr.50 okanye EN 10025 S355JR) Izikhonkwane zendawo eziqinileyo ezine-± 0.01 mm zokunyamezelana kwedayamitha Amandla okubamba alungelelaniswa ngokwejometri edibeneyo-hayi imimiselo "ephezulu / ephakathi / ephantsi". Izikhuselo ezinikezelweyo zesitshizi ezikhwela *ngaphandle* kokuphazamisana neengile zokufikelela kwitotshi Xa iWelding Fixtures iba yinxalenye yeNkqubo yakho yeDFM
Abanye basenokuphikisa ngelithi: “Siza kutshiselisa kuqala, emva koko sitshintshe umphezulu wedatum.” Oko kongeza iindleko, ukulibaziseka, kunye nomngcipheko we-scrap. E-Haijun, sibethelela ingqiqo yoyilo kwinqanaba lokuqala loYilo lophononongo lweMveliso. Ukuba isibiyeli sakho sinemingxunya emithathu ekhwele iplanar eqelelene nge-120 mm kwaye ifuna i-90° i-welds yefillet kwiiflange ezimbini ezimeleneyo-siya kuphawula ukuba eyona ndawo ifanelekileyo kufuneka ifumane ukusuka kowona mphezulu mkhulu caba *kuqala*, hayi owona mphetho umncinci. Ngoba? Ngenxa yokuba uqhagamshelwano lommandla womphezulu lunciphisa ukuphambuka phantsi komthwalo obambezelayo ukuya kuthi ga kwi-60% xa kuthelekiswa neendawo ezihlala kuzo kuphela.
Oku akuyothiyori. Enye iOEM yezolimo yaseYurophu yehlise izinga lokupasa kwabo emva kweweld ukusuka kuma-82% ukuya kuma-99.4% emva kokwamkela isicwangciso sethu sokwenza iindlwane. Ukuseta kwabo kwantlandlolo basebenzise izikhonkwane zedowel kwiimpawu zesibini. Eyethu ibambelele kwiradiyasi yokuqala yokugoba-eyona ichaphazeleka kancinci yi-springback. Isiphumo? Ukuphinda kusetyenzwe kancinci, kuqiniswe ukuthotyelwa kwe-GD&T, kunye nobude obungaguqukiyo be-arc kuzo zonke iindawo ezili-14 zokudlula.
Indlela esiqinisekisa ngayo ukusebenza kweFixture-Ngaphambi kokuba Usike isinyithi
Asithembeli kwi-FEA emileyo yodwa. Lonke umdlalo uphantsi kwezigaba ezintathu zokuqinisekisa:
Uvavanyo lomjikelo wokuhlekisa: Ukomisa kunye namalungu amele kwisantya esipheleleyo semveliso-ukulinganisa ukunxiba kwendawo, ukudinwa kwe-clamp, kunye nokufikelela kwimvulophu yomsebenzisi Ukuqinisekiswa kokumelana ne-Spatter: Imizuzu eyi-15 yokulinganisa i-MIG welding usebenzisa amaxabiso ombane ombane kunye nokuxuba igesi ekhuselayo-emva koko ujonge ukuncamathela kwesitshizi kwiindawo ezibalulekileyo. Uvavanyo lwe-thermal soak: Ukubamba indawo kwi-85°C iiyure ezi-2 ukulinganisa iimeko zomgangatho wevenkile zasehlotyeni-ukukhangela kwakhona zonke iindawo zedatum ngeCMM Olu qeqesho lucacisa ukuba kutheni abathengi bethu bexela ukungathotyelwa okunxulumene nokungabikho kwiingxelo zohlolo lokugqibela kwiinyanga ezingama-27 ezidlulileyo. Kwakhona kuthetha ukuba akukho msebenzi wokuphinda umangaliswe xa ulinganisa ukusuka kwiiyunithi zeprototype ezingama-50 ukuya kwi-2,000 / inyanga yokuvelisa.
Ukusuka kwi-Fixture Design ukuya kwi-Full-Welded Assembly-I-One Integrated Workflow
Ukuhlanganiswa ngokuthe nkqo kutshintsha yonke into. E-Haijun, elona qela liyila isixhobo sakho se-weld likwaqhuba inkqubo ye-CNC press brake eyenza inxalenye, ikhethe ibakala elingenasiphene lokumelana nomhlwa, kwaye iqinisekisa amandla okugqibela e-weld nge-ISO 15614-1. Akukho handoffs. Akukho lahleko yoguqulo phakathi kwamasebe. Xa isibiyeli sakho sidinga i-3-mm fillet weld kwi-0.8-mm ye-aluminium flange, iinjineli zethu zokulungisa zithetha ngokuthe ngqo neengcali zethu zokuwelda-kuba zabelana ngomgangatho wevenkile omnye.
Yiloo ndlela esizisa ngayo iindibano ezigcwele i-welded ezine-callouts ze-GD & T ezigcinwe kwi-± 0.2 mm-nakwiindawo ezine-12+ ze-weld joints kunye ne-mixed-material interfaces. Akukho zikontraka zangaphandle. Akukho nto imangalisayo yokunyamezela. Ulawulo lwenkqubo olubhalwe nje, ukusuka kwikhoyili ekrwada ukuya kwikhreyithi yokuthumela.
Kubavelisi abanyangayo ijig kunye ne-fixture welding njengeziseko zobunjineli-ezingasetyenziswanga-umahluko ubonisa kwisivuno sokuqala, izinga lokungaphumeleli kwentsimi, kunye nokugcinwa kwabathengi. Ukuchaneka akufezeki kwi-weld pool. Itshixiwe ngaphambi kokuba i-arc ibethe. Qala ngesixhobo esifanelekileyo. Yakha ukusuka apho.
