Gusudira ntabwo ari ubushyuhe gusa no kuzuza ibyuma-bijyanye no kugenzura. Mugihe igice gihinduye mm 0.2 munsi yumuvuduko ukabije, umugozi weld utakaza guhuza. Kugoreka byinjira. Imirimo ikurikira. Mu kuvanga cyane, guhimba amajwi make-cyane cyane ku nyuguti, guteranya chassis, cyangwa sisitemu yo guhuza ubuhinzi-ibi ntabwo ari ingaruka zishingiye ku nyigisho. Twabibonye ubwacu: umukiriya muri Wisconsin yakuyeho 17% by'icyiciro cya mbere kuko jig gakondo yabo ya angle-fer ntishobora kwihanganira kwihanganira ibyobo bitandatu bizamuka kuri traktori ya aluminium. Bahinduye kuri a Imeza yo gusudira 3D. Ibisigazwa byagabanutse kugera kuri 0.8%. Igihe cyigihe cyagabanutseho 41%.
Icyitonderwa gitangirira aho isahani fatizo ihurira na pin
Nukuri Imeza yo gusudira 3D ntabwo icyuma kibase gifite icyuho cyacukuwe. Ni umuhuzabikorwa-ushingiye kumurimo wubatswe wubatswe hafi ya axe eshatu zisubirwamo: X (umurongo utambitse), Y (inkingi itambitse), na Z (guhuza uburebure bwa vertical). Buri mwobo - mubisanzwe M6, M8, cyangwa 1 / 4′-20 - wicaye kuri gride itomoye (mubisanzwe mm 50 cyangwa ikibanza cya santimetero 2) hamwe no kwihanganira imyanya ≤ ± 0.05 mm. Amapine afunga muri ibyo byobo, hanyuma wemere ibikoresho bya modular: impagarike zifatika, guhagarika guhagarika, kuzenguruka, cyangwa kugenera imashini zakozwe kugirango zihuze igice cya datum.
Ubu buryo bwa geometrie-bwambere busimbuza gukeka hamwe nuburyo bukurikiranwa. Ntakindi imirongo yandika, ntakindi kigeragezo-na-kwibeshya. Umukiriya umwe mu Budage yagabanije igihe cyo gushushanya kuva ku minsi 11 kugeza ku masaha 38 - ntabwo ari ugutanga CAD, ahubwo yakoresheje uburyo bwa digitale yububiko bwibitabo busanzwe bwa pin-na clamp muri SolidWorks. Ba injeniyeri babo ubu bubaka ibintu mbere yuko ibikoresho fatizo bigera.
Inyungu nyayo yerekana mugihe cya itera. Iyo abatanga ibinyabiziga bya Tier-1 bakeneye kwemeza ibice bitanu byerekeranye na bateri nshya ya EV, bakoresheje imbonerahamwe imwe ya 3D hamwe nibyuma bisimburana. Inyubako zose uko ari eshanu zisangiye guhuza ibikorwa. Gutandukana ku bipimo byashushanijwe - ntabwo bihabanye n'ibishushanyo by'izina - ahubwo byerekanwe ku mbonerahamwe bwite ya metero. Ayo makuru yatanzwe mu buryo butaziguye muri DFM yo gusubiramo.
Kuki amaduka menshi ahagarara kuri "semi-modular"
Bamwe mu bakora inganda bita isahani iyo ari yo yose ifite T-bolts “ameza yo gusudira 3D.” Ntabwo aribyo. Ubushobozi bwa 3D nyabwo busaba imico itatu idashobora kuganirwaho:
Kubaka base base. Igishushanyo mbonera: CNC irambiwe, ntabwo yacukuwe; buri mwobo wagenzuwe binyuze muri CMM ukoresheje ingingo zerekana - ntabwo ari intera hagati-hagati, ahubwo ni perpendicularité ku ndege yo hejuru Z-axis gusubiramo. Twagerageje imbonerahamwe yatsinze igenzura ryerekanwe ariko birananirana gusiganwa ku magare: nyuma yamasaha 12 kuri 60 ° C, uburebure bwa pin bwatembye mm 0,13 kubera amakaramu ya aluminiyumu atabigenewe. Iyo drift yonyine yatesheje agaciro GD&T guhamagarwa kuri perpendicularity kuri flanged weld. Kuramba-kwisi kuramba cyane kuruta udutabo twinshi.
Kwishyira hamwe-ntabwo ari kwigunga-niho hongerwaho agaciro
Imeza yo gusudira ya 3D yihariye itanga ibisobanuro. Ariko iyo ihagaritse urunigi rwuzuye - kashe, kunama, gusudira, kugenzura - ifungura inyungu zinjira nta mashini nimwe ishobora guhura. Muri Botou Haijun Metal Products Co., Ltd., dukoresha ameza ya 3D ntabwo ari ahakorerwa imirimo, ariko nka sisitemu yo hagati yibice bigize selile zacu.
Dore uko ikora: Amazu y'ibyuma ashushanyije cyane atagira ibyuma biva mu icapiro ryacu rya hydraulic. Ubuso bukomeye bwa datum bugenzurwa kuri CMM yacu-noneho aho iherereye ugereranije nimbonerahamwe yinkomoko yanditswe. Iyo coorateur set igenda ihita kuri robot ya MIG. Clamps. Urutonde rukurikiranye. Nyuma yo gusudira, CMM imwe igenzura kugoreka dosiye yambere yashizweho - ntabwo irwanya igishushanyo, ahubwo irwanya intego ifatika yafashwe kuri t = 0.
Nta gihombo cy'ubuhinduzi. Nta nyandiko-mvugo. Gusa bisubirwamo, byumvikana geometrie - hejuru ya kashe, gukora, gusudira, na QC. Niyo mpamvu abakiriya bubaka hydraulic valve manifolds kumasoko ya peteroli yo muburasirazuba bwo hagati bavuga ko zeru zananiranye mumezi 36: buri ruganda rusudira rufite imiterere imwe yubushyuhe, kugenzura icyuho kimwe, kwinjira mumizi - kuko igice kitigeze gisiga umwanya wacyo wa tekinoroji.
Tangira kumurongo wawe udakomeye - ntabwo ari bije yawe nini
Ntukeneye imbonerahamwe ya 3m × 2m kugirango wungukire no gusudira 3D. Tangira ntoya: menya ingingo imwe yububabare isubirwamo - nko guhuza umwobo udahuye kumurongo wunamye, cyangwa urupapuro rwintambara mu nteko zoroheje-hanyuma ukabihuza na sisitemu ntoya yemewe ikemura. Imeza ya 1000 × 750 mm hamwe na M8 grid hamwe na 12-pin kit ikora 83% yimyenda mito mito mito tubona burimunsi.
Baza uwaguhaye isoko kubimenyetso - ntabwo asabwa. Saba raporo ya CMM kugirango ibeho neza. Baza amakuru yikizamini ku mbaraga zo kugumana nyuma ya 10,000. Kugenzura niba isahani yabo fatizo ikoresha ibyuma bisanzwe - ntabwo ari "karubone iremereye" gusa. Emeza niba clamp zabo zirimo isura ikomye, ntabwo ari kashe mpapuro.
Kuberako guhuza neza ntabwo ari ukugura ibyuma. Nibijyanye no gufata intego yubuhanga-no kuyifata, neza, kugeza arc yanyuma isohotse. Ibyo guhuzagurika byuzuzanya muri buri weld, buri shift, buri mwaka. Kandi burya nuburyo bwihuse, bukomeye bwo guhimba ibyuma bitangira-bitari kumuri, ahubwo kumeza.
