Iivenkile zokwenza izinto zale mihla zijongene norhwebo olungaguqukiyo: ukuchaneka kufuna izixhobo ezingqongqo, kodwa ubuchule bemveliso bufuna ukuguquguquka. I Itafile yendibano ye-3D ye-welding eguquguqukayo Isombulula loo ngxwabangxwaba—kungekhona njengokulalanisa, kodwa njengesisombululo esinobunjineli. Siyibonile iyeka imijikelo yokuphinda isebenze kwimigca yeemoto, inqumle ixesha lokuhamba nge-70% kwiiprototypes zoomatshini bezolimo, kwaye ishenxise ukhukuliseko olunexabiso eliphezulu ngexesha lolandelelwano lwe-weld yezikhululo ezininzi. Le ayisiyonto enye imodyuli yokusebenzela. Yinkqubo yokumisa esekelwe kukulungelelanisa apho ukuphindaphinda kuhlangabezana nokuguquguquka-ukuhla ukuya ku-± 0.1 mm ngaphesheya kwe-2 m × 3 m indawo yokusebenza.
Kutheni iiTayibhile zeWelding yesiNtu zisilela phantsi komthwalo wehlabathi lokwenyani
Iivenkile ezininzi zisaxhomekeke kwiitafile zegrid esisigxina okanye kwiipleyiti ezidityanisiweyo ngesandla. Enyanisweni, ezo nkqubo ziqhekeka ngokukhawuleza. Silinganise umndilili wexesha lokutsiba ukusuka kwimizuzu engama-22 ukuya ngaphezulu kwemizuzu engama-90 xa utshintshela phakathi kweentsapho zezibiyeli-nokuba nobukhulu obufanayo bemathiriyeli. Ngoba? Ngenxa yokuba ukupakishwa kokunyamezela akuyothiyori. Ulungelelwaniso lwe-0.3 mm kwindawo yokubambelela luba yi-1.8 mm ukutenxa kumthungo we-weld emva kokulungiswa okuthathu okulandelelanayo. I-Thermal distortion iyayidibanisa. Kwaye nje ukuba wongeze inkqubo yerobhothi, iimpazamo ezincinci zedatum zinyanzela uhlengahlengiso olupheleleyo-hayi nje ukubamba phezulu. I Itafile yendibano ye-3D ye-welding eguquguqukayo iyayiphelisa loo ntsizi. I-T-slots yayo yentsimbi eqinile yamkela iindawo ezihlala kuzo, izixhasi eziguquguqukayo ukuphakama, kunye ne-kinematic clamps-zonke zitshixiwe nge-ISO-standard M8 dowel pins. Onke amacandelo abhekisa kwiplani enye yedatha esisiseko. Akukho ngqikelelo. Akukho mpazamo yongezeleka.
Yintoni eyenza "i-3D Flexible" Ngaphezulu kweJargon yokuthengisa
"I-3D flexible" ithetha ulawulo lwe-volumetric lokwenyani-kungekhona nje ukulungiswa kwe-X / Y. Kumgangatho wethu wokuvelisa, savavanya iinkqubo ezine ezikhokelayo ecaleni-ngecala sisebenzisa icandelo lovavanyo olulandelwa yi-CMM: isakhelo se-chassis yensimbi engenasici kunye ne-14 ye-weld joints, i-6 imingxuma yokunyuka, kunye ne-callouts ye-GD & T ebalulekileyo (± 0.15 mm ukunyamezela isikhundla, i-0.5 mm flatness). Uyilo olunye kuphela olugcine ukuthotyelwa okugcweleyo kuzo zonke ii-20 eziphindayo ezakhayo: inkqubo ene-Z-axis micro-adjustment ezimeleyo kwikholamu nganye yenkxaso, idityaniswe neebhloko zokukhomba indawo ezimbini ezitshixayo zombini indawo ethe tye *kunye * nokuma ngokuthe nkqo ngaxeshanye. Lowo ngumahluko phakathi "kokulungiswayo" kunye "nokuphinda." Yiyo loo nto abathengi abakwiTier-1 yeentambo zokubonelela ngeemoto bachaza olu lungelelwaniso-kungekhona lula, kodwa ukulungela ukungeniswa kwePPAP. Ukugqitywa komphezulu kubaluleke kakhulu. Ezi tafile zisebenzisa i-nitrided 45# iintsimbi zentsimbi, azipeyintwa intsimbi ethambileyo. Baxhathisa ukuncamathela kwe-spatter, basinda kwi-500+ ye-thermal cycles ngaphandle kwe-warping, kwaye bagcina ukuphindaphinda kwendawo emva kokucoca imihla ngemihla ngeebrashi zocingo kunye nomoya ocinezelweyo.
Ukudityaniswa kulapho uninzi lweeProjekthi zikhubeka khona-Nantsi indlela yokuyinqanda
Abanye abathengi bacinga ukuhambelana kweplagi kunye nokudlala. Inyani inzima ngakumbi. Siye sabona ukusilela okuqhelekileyo kokudityaniswa okuthathu: Okokuqala, ukungahambelani kobunzulu be-clamp stroke-i-standard pneumatic clamps kaninzi ayinayo i-45 mm yokuhamba efunekayo kwiindibano ezipakishweyo. Okwesibini, imvulophu yokufikelela kwi-robot engachazwanga: i-2.5 m ububanzi betafile buvakala kakuhle de i-robot yakho ye-welding ayikwazi ukufikelela kwindawo ephakathi ngaphandle kokubeka kwakhona. Okwesithathu, amaxwebhu angekhoyo okulandelelwa kwe-metrology. Wonke umntu ufanelekile Itafile yendibano ye-3D ye-welding eguquguqukayo kufuneka ithunyelwe ngengxelo yolungelelwaniso eqinisekisiweyo-isayinwa, yabhalwa umhla, kwaye ibotshelelwe kwimigangatho enokulandeleka ye-NIST. E-Botou Haijun Metal Products Co., Ltd., sibandakanya loo ngxelo kunye nophononongo olupheleleyo lweDFM lwesicwangciso sokufumana indawo yenxalenye yakho ngaphambi kokusika nayiphi na intsimbi. Senza imephu yolandelelwano lwe-weld yakho, sichonge iindlela ezinokubakho zokugqwethwa kwe-thermal, kwaye sicebisa indawo yendawo ngokusekwe kumandla emveliso-hayi iitemplates eziqhelekileyo. Yiloo ndlela esihambisa ngayo imvume yenqaku lokuqala kwi-92% yeeprojekthi ezintsha.
I-ROI yokwenyani iqala ngobungakanani be-Smart-kwaye iphele ngeNkxaso
Musa ukujonga ngaphezulu. Itheyibhile ye-3 m × 4 m ivakala iyamangalisa-kodwa ukuba inxalenye yakho enkulu yi-1.2 m ubude, uhlawula ukuqina okungasetyenziswanga kunye nendawo eyongeziweyo yomgangatho. Qala ngemvulophu yakho enkulu *plus* 300 mm isithinteli kwicala ngalinye ukuze ufikelele kwi-clamp kunye neradiyasi yerobhothi. Emva koko qinisekisa ukuphatha izinto: ngaba ikhreyini yakho yangaphezulu ingaphakamisa itafile egcwele ngokupheleleyo? Ngaba i-sleb yakho yekhonkrithi iyahlangabezana ne-25 MPa ubuncinane bemfuno yamandla oxinzelelo? Sincede abathengi banqande i-18,000 yeedola kulungiso lwesiseko ngokubamba kwangoko. Ugcino lulula kunokuba uninzi lucinga. Akukho hydraulics. Akukho layisensi yesoftware. Amanqaku egrisi nje ngekota kwizikhokelo zemigca kunye noqinisekiso lonyaka lokunxitywa kwephini lendawo kusetyenziswa igeyiji elungelelanisiweyo. Inkxaso yethu ibandakanya ukujongwa kweengxaki ezikhokelwa yi-CMM-sabelana ngesikrini, sigqume ingxelo yakho yokuhlola, kwaye sikuhambise kwisenzo sokulungisa ngaphantsi kwemizuzu engama-20. Ukutshintsha okungxamisekileyo, sibambe isitokhwe ekrwada sazo zonke iiprofayili eziqhelekileyo ze-T-slot kunye neziseko zendawo. Ixesha lokukhokela: Iintsuku zokusebenza ezili-11, hayi iiveki ezili-12. Eso santya sivela ekudityanisweni okuthe nkqo-isitampu, umatshini, unyango lobushushu, kunye nendibano yokugqibela phantsi kophahla olunye kwisiXeko saseBotou.
Xa i-weldment yakho elandelayo idinga u-zero rework, amaxesha omjikelezo ongaguqukiyo, kunye nokuphindaphindwa kwebakala lobunjineli, i Itafile yendibano ye-3D ye-welding eguquguqukayo ayilophuculo-yinto esisiseko. Itshintsha ulawulo lomgangatho phezulu, ijike utshintsho kwi-fixture ibe yimisebenzi yemizuzu eli-15, kwaye yenza ukuthotyelwa komgangatho kuqikelelwe-kungekho themba. Lo ngumgangatho wenjineli esiwenza kuwo. Lo ngumgangatho olinganisela abathengi bethu.
