Iyo ba injeniyeri bagaragaje imashini ikora ibyuma kuri hydraulic valves, amazu ya pompe, cyangwa shitingi ya winch, ntabwo batumiza igice gusa - biyemeje gutuza kurwego munsi yumuvuduko wa bar-350, ubunyangamugayo bwa microstructural nyuma yumukino wo gusiganwa ku bushyuhe bwumuriro, hamwe no kurangiza hejuru birwanya kwambara nabi mumigezi yuzuye amavuta yumucanga. Twabonye imishinga myinshi ihagarara mugihe abatanga isoko bafata ibyuma nkibikorwa byibicuruzwa-hanyuma bagatanga imashini kubucuruzi bwabandi bantu bafite ibisobanuro bidahuye na GD&T, inyandiko zivura ubushyuhe zidahuye, cyangwa ntabishobora gukurikiranwa na ASTM A48 Icyiciro cya 350 cyibikoresho.
Impamvu Gukora Ibyuma Byuma Byananiranye-Kandi Mubyukuri Bikora
Gutera ibyuma byonyine ntabwo byemeza imikorere. Icyuma cya grafite ya grafite itanga ibara ariko igabanya imbaraga zingana; ductile fer ya spheroidal grafite itezimbere ubukana ariko bisaba kugenzura neza nodularisation mugihe cyo gusuka. Ongeraho imashini ya CNC-hanyuma utangire ibice bishya byananiranye: kugoreka imihangayiko isigaye iturutse ku gukonjesha kutaringaniye, ibimenyetso byo kuganira kuri bore ya silinderi yoroheje, cyangwa ubukana butera ibikoresho bitaragera igihe cyo kurangiza.
Twigeze gukora icyiciro cya piston pompe ya silinderi kubera ko uruganda rwakoresheje ibisigazwa byasubiwemo nta genzura ryerekanwe. Ihinduka rya silikoni yavuyemo ryahinduye ubukana buva kuri 220-240 HB bugera kuri 265 HB muri zone zaho - bihagije kugirango uhindure mm 0,012 mugihe cyo kurambirwa. Niyo mpamvu tugerageza gushonga hamwe nisesengura rya OES * mbere yo gusuka - kandi tukagenzura ubukana bwa post-cast ahantu hatatu kuri casting, ntabwo ari imwe gusa.
Intsinzi nyayo-yisi ishingiye ku guhuza vertical. Ibishingwe, amaduka yimashini, hamwe na metero bigomba gusangira amateka yubushyuhe bumwe, gahunda ya CMM, icyemezo kimwe cyibikoresho. Nta ntoki. Nta gitekerezo kijyanye n'amafaranga yo gutunganya "bisanzwe". Mugihe umukiriya atwoherereje AMS 5387 cobalt alloy plug ishushanya hamwe na ± 0.005 mm kwihanganira imyanya kuri mwobo wa dowel esheshatu, turasubiza mumasaha 48 - ntabwo hamwe na cote, ariko hamwe na raporo yakozwe yerekana aho EDM itobora ikubita gucukura imyanda, aho kugabanya imihangayiko mbere yo gukomera birinda kubyara ovality, nuburyo tuzemeza kuzenguruka dukoresheje Zeind CONTURA G2.
Bane Bidashobora kuganirwaho kubutumwa-Bunegura Ibyuma
- Gukurikirana ibikoresho kugeza kumubare wubushyuhe-Ntabwo ari urusyo gusa, ariko raporo yuzuye ya OES, utubari twipimishije twabitswe kuri tombora, namafoto ya microstructure yagenzuwe na ASTM E112
- Imashini nyuma yo kugabanya imihangayiko-Dufata casting kuri 550 ° C mumasaha 4, hanyuma ukonje kuri ≤30 ° C / isaha mbere yuko gukuramo ibyuma bitangira
- GD & T-gahunda yambere yo kugenzura—Ibikorwa bya CMM byubatswe mubishushanyo byabakiriya, ntabwo ari inyandikorugero rusange; datum iranga igeragezwa mbere, imikorere yimikorere iheruka
- Kwemeza ubusugire-Ntabwo ari indangagaciro za Ra gusa, ahubwo ni umweru-wo gutahura ukoresheje SEM / EDS kubireba kashe ya kashe igaragara kuri serivisi ya H2S
Aho Abaguzi Basanzwe Bagwa Mugufi (Nuburyo bwo Kubibona)
Abacuruzi bamwe bamamaza "ibyuma bikozwe neza byakozwe neza" ariko bagahereza hanze kububiko buke budafite ISO 9001: 2015 Ingingo 8.5.2 igenzura ibicuruzwa bidakora neza. Abandi bakoresha porogaramu rusange ya CNC ifata amafaranga yimigabane imwe - birengagije uburyo itandukaniro ryumusenyi rigira ingaruka kumubyimba wurukuta muri geometrike igoye nka moteri yimodoka ya winch center shaft rollers.
Twabonye iki cyuho mugihe cyubugenzuzi buherutse gukorwa: umunywanyi yavuzeko umubiri wumuvuduko wumuvuduko ufite uburebure bwa mm 12 byibura - ariko gushushanya kwabo kwerekanaga amafaranga 8 mm gusa. Mubikorwa, 30% byibice bisabwa gusudira mbere yo gutunganya. Ibyo ntabwo aribyo. Nibyo gukeka kwiyoberanya nkubushobozi.
Baza uwaguhaye ibyo bibazo mbere yo kurekura POs:
- Urashobora kunyereka ibiti bitatu byanyuma bishonga kuri ASTM Icyuma gihindagurika?
- Ni ubuhe butumwa bwawe bwemewe bwemewe hagati ya as-cast hamwe nuburemere bwa nyuma bwa pompe ya kg 42?
- Raporo yawe ya CMM ikubiyemo amakuru yindishyi zumuriro winjiye mumadirishya yo kugenzura amasaha 8?
Kubaka Icyizere - Ntabwo ari Ibigize gusa
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. itanga imashini ikora ibyuma ibisubizo aho kwizerwa bidashobora kuganirwaho-sibyo kuko tubisaba, ariko kuberako inzira yacu isiga ibimenyetso. Buri cyuma cyerekana umuvuduko woherejwe hamwe na QR yanditseho ikirango gihuza dosiye yuzuye yo kugenzura: ibikoresho fatizo, ibishushanyo mbonera byo kuvura ubushyuhe, ibicu bya CMM, hamwe namakarita yubusa. Abakiriya muri Amerika ya Ruguru hamwe n’Uburayi bakoresha ayo madosiye ya ASME Igice cya VIII Igice UG-120 igenzura ryubahirizwa. OEMs yo mu majyepfo yuburasirazuba bwa Aziya iberekeza mugihe cya APQP Icyiciro cya 3.
Ntabwo dukurikirana amajwi. Twibanze ku bice aho gutsindwa bisobanura igihe cyo gutinda, guhungabanya umutekano, cyangwa ibihano byateganijwe - nka T800 ya cobalt ishingiye kuri nozzles ikoresha umunyu ushonga wa 450 ° C mu bimera bikomoka ku zuba. Hano, icyuma gipima 0,02-mm ntabwo ari "gutandukana kworoheje." Nuburinganire bwimikorere yihutisha isuri 300%.
Ejo hazaza ni mubikorwa bivangavanze: gushora imari hafi ya net hamwe na CNC yakozwe na kashe ya kashe, amazu yumucanga hamwe numuyoboro wa coolant warangiye ukoresheje gusya byihuse. Turimo kwagura R&D kumurongo wogukonjesha no gukonjesha no gutezimbere mugikorwa cyo kunyeganyega kugirango tumenye igihe nyacyo cyo kuganira mugihe cyo kurambirwa umwobo wimbitse ya silinderi.
Niba umushinga wawe utaha ubisabye imashini ikora ibyuma ifata ukuri kuri 300 ° C, ikarokoka 10⁶ yikurikiranya ryumuvuduko, kandi igera hamwe na zeru zitunguranye-tangira ukoresheje ibintu bifatika, ntabwo ari igiciro kuri kilo.
