Iyo ushakisha neza uruganda rukora imashini zubuhinzi abafatanyabikorwa, injeniyeri n'abashinzwe gutanga amasoko ntibakeneye gusa abatanga isoko-bakeneye abafatanyabikorwa ba tekinike bumva uburyo kwihanganira mm 0,02 kuri pompe ya pompe bigira ingaruka kumurima munsi yumuvuduko wa hydraulic 350. Twabonye imishinga myinshi yatinze - ntabwo ari inenge zishushanyije, ahubwo nubuhanga bwibikoresho bidahuye, microstructure ya cobalt alloy idahuye, cyangwa drift ibipimo nyuma yo kuvura ubushyuhe. Niyo mpamvu imikorere ikora itangira kera mbere yuko chip ya mbere icibwa.
Impamvu Ubuhanga Bwibintu Bifite akamaro Kurenza Imashini
Inganda nyinshi ibyuma byimashini. Bake shobuja AMS 5387 cobalt-nikel ivanze-cyane cyane iyo ijugunywe mumibiri igoye ya pompe ifite imiyoboro ikonjesha imbere hanyuma ikarangiza ikozwe kuri ± 0.015 mm GD&T guhamagara. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Superalloys ishingiye kuri cobalt ntabwo ari "amahitamo." Nibintu fatizo byumuvuduko wamashanyarazi, amazu ya silinderi, hamwe na shitingi ya shitingi ya shitingi ikoreshwa mubisarurwa byumuceri, abatwara ibisheke, hamwe nudukoko twinshi tw’amafarashi hirya no hino muri Aziya yepfo yepfo yepfo na Amerika ya ruguru.
Twahuye nabakiriya bagaragaje T800 cobalt alloy yo guterana nozzle-gusa twakiriye ibice byacitse mugihe cyamagare yubushyuhe. Impamvu? Imiterere idahuye nkimiterere yintete hamwe nicyemezo cyabatanga ibyemezo. Igisubizo cyacu: ibisobanuro byuzuye bivuye kumpapuro zishyirwaho mbisi (ASTM A975, AMS 5719) binyuze mubisubizo bifatika, gusaza, no kwemeza CMM ya nyuma. Nta bitekerezo. Buri tombora itwara raporo ya metallurgical ihujwe numubare wubushyuhe bwayo.
Ibi ntabwo ari theoretical. Mu mushinga umwe uherutse, OEM yu Burayi yongeye guhindura imashini yimodoka ya hydraulic ya moteri kugirango igabanye ibiro. Abatanga isoko yumwimerere ntibashobora kwihanganira ibyambu bitatu bihuza ibyuka byumuvuduko mwinshi mubyuma byangiza. Twahinduye ishoramari ASTM A48 Icyiciro cya 65-45–12 Icyuma cyangiza, twongera imbaraga zo guhangayika mbere ya CNC, kandi dutanga umusaruro wa 100% wambere wambere kuri 0.012 mm yiruka - byagenzuwe na optique ya scan.
Kwishyira hamwe bihagaritse mubyukuri bitanga umutekano
Outsourcing casting, gutunganya, no kurangiza kubacuruzi batandukanye bigwiza ibyago: kugoreka ubushyuhe hagati yimikorere, kurangiza kurangiza bidahuye, no gutakaza ibisobanuro. Turagenzura uko ari batatu mubikoresho bimwe byubahiriza ISO muri Qingdao-kubera ko ituze ryurwego ridashobora kugenzurwa; byashizwe mubikorwa.
- Abakinnyi: Imirongo yumucanga nishoramari byahinduwe kugirango bicye cyane, ibyuma bidafite ubunyangamugayo buhanitse hamwe nicyuma kitagira umuyonga - ndetse no kuri geometrike itari isanzwe nka fondasiyo ya pompe ya asimmetrike hamwe nudusanduku twiziritse.
- Imashini: Multi-axis CNC yibigo hamwe nubushakashatsi bwakozwe, bushobora kurangiza ibyuma 17-4PH bikomye kuri Ra 0.4 µm nta rework
- Kurangiza: Passivation, electropolishing, hamwe na HVOF yoguhitamo guhuza ibikorwa bikenewe-ntabwo ari ubwiza gusa
Umukiriya umwe yasabye icyuma cyuma cyuma kitagira ingese hamwe na nitride yo kwambara hamwe nibinyamakuru bitwaye neza. Aho guha abadandaza batatu, twakoresheje urutonde rwose murugo: gukina nabi → guhangayika kugabanya → kurangiza CNC → nitride yatoranijwe → ikarita ya nyuma ya CMM. Igihe cyo kuyobora cyagabanutseho 37%. Ibisigazwa byagabanutse kuva kuri 8.2% bigera kuri zeru.
Ubufatanye bwubwubatsi butangira mbere ya PO
“Urashobora gukora ibi?” ni ikibazo cya mbere. Ibikwiye ni: “Iyi geometrie izarokoka kwaguka k'umuriro ahantu h'umuceri wa 55 ° C?” cyangwa “Ese iyi GD&T itondekanya yemerera guhagarika kashe ishobora gutegurwa mu masaha 5.000 yo gukora?”
Dufata buri gishushanyo cyo gusubiramo nk'isomo rihuriweho-gusuzuma. Igihembwe gishize, twashyize ahagaragara uburyo bwo kwihanganira imyanya idakwiye ku mubiri wa valve - wasaga neza ku mpapuro ariko byatera gutandukana kwa 12% kubera guhuza icyambu kidasanzwe. Twasabye gahunda ya datum ivuguruye kandi dusangiye amakuru yo kwigana yerekana kugabanuka k'umuvuduko. Umukiriya yemeye impinduka-kandi yongereye amasezerano yumwaka.
Inkunga yacu ikubiyemo ibisobanuro bya GD&T, ibitekerezo byakozwe, hamwe na prototyping byihuse ukoresheje hafi-net-shusho ya casting + imashini yoroheje. Kubuhinzi bwa OEM bugabanuka kuva mubyiciro byicyitegererezo kugeza kuri 500-buri kwezi ikora, ubwo bufatanye hakiri kare burinda ibiciro bihendutse.
Kwizerwa Urashobora kugenzura - Ntabwo ari amasezerano gusa
"Yizewe OEM utanga" ntacyo bivuze nta gihamya. Dore ibyanditswe, bipimwe, kandi bigumana kuri buri cyiciro:
- Kugenzura ibikoresho byinjira: Spectrometry + raporo yikizamini kuri tombora
- Igenzura-mubikorwa: CMM isikana mubyiciro bikomeye, ntabwo igenzurwa ryanyuma
- Isohora ryanyuma: Raporo yikigereranyo + isuzuma ryerekanwa + ikizamini gikora (urugero, gupima igitutu kuri 1.5 pressure igitutu cyakazi)
- Gukurikirana: Urunigi rwuzuye kuva nimero yubushyuhe kugeza kubyoherejwe bigaragara
Dukorera abakora ibikoresho byubuhinzi kwisi yose kuko bisaba guhuzagurika - ntabwo byateganijwe gusa, ariko mumyaka myinshi. Iyo sisitemu ya hydraulic yumusaruzi wawe iterwa na plaque ya cobalt irokoka irokoka 10,000 inzinguzingo, "byiza bihagije" ntabwo biri mubigambo. Niyo mpanvu portfolio yacu yibanze ikomeza kwibanda cyane: ububiko bwumuvuduko, amazu ya silinderi, urufatiro rwa pompe, hamwe na sisitemu ya winch-nta gutandukana, nta gutandukanya ubushishozi bwa domaine.
Niba urimo gusuzuma uruganda rukora imashini zubuhinzi, baza ibibazo bibiri: Ese sisitemu yubuziranenge itangirira ku cyemezo cyibikoresho-cyangwa kuri raporo yanyuma yubugenzuzi? Kandi barashobora kukwereka isesengura-nyaryo ryananiwe kwisi aho impinduka zabo zabujije ikibazo cyumurima? Aho niho hatangirwa kwizerwa.
