QT450-10 itangwa ryuruganda ntabwo ari ibintu bifatika-ni isezerano ryimikorere. Iyo imibiri ya hydraulic, inzu ya pompe, cyangwa shitingi ya winch igomba kurwanya umunaniro mugihe cyikizunguruka mugihe ufite kwihanganira GD&T, icyuma cya QT450-10 gitanga impagarike ikwiye: imbaraga za MPa 450, kurambura 10% byibuze, hamwe na tekinike ishobora gutegurwa nyuma yo gufatana. Ariko gushakisha QT450-10 gukina ntabwo ari ugushaka * ibishingwe byose. Nibijyanye no gufatanya nuwitanga kugenzura metallurgie kuva kumurongo kugeza kuri lathe-kandi niho guhuza vertical bihinduka kutaganirwaho.
Kuki QT450-10 isaba ibirenze gukina bisanzwe
Twabonye ingingo eshatu zisanzwe zananiranye mumishinga ya QT450-10: nodularity idahuye itera kuvunika imburagihe mu mpagarara nyinshi; gusigara biterwa no kugoreka mugihe cyo gutunganya CNC ya nyuma; na microcrake yo hejuru yagaragaye gusa nyuma yo kugerageza igitutu. Ibi ntabwo ari ugukora "amakosa." Nibimenyetso byakazi byacitsemo ibice-aho guta, kuvura ubushyuhe, no gutunganya bibera kubacuruzi batandukanye bafite idirishya ridahuye.
Ibikoresho bya QT450-10 bishingiye ku kugenzura neza imiti ya magnesium, igihe cyo gutera, hamwe nigipimo cyo gukonjesha. Gutandukana kwa 3 ° C mubushuhe burashobora guhindura nodule kubara 20%. Niyo mpanvu ibyemezo byibanze byemewe bikurikiranwa-ntabwo ari impapuro, ariko nkumuhuza muzima kuri raporo zisesenguye hamwe namateka yubushyuhe. Ku kigo cyacu cya Qingdao, buri cyiciro cya QT450-10 gitwara imiti yuzuye (C: 3.4–3.8%, Si: 2.2-22.8%, Mg: 0.03–0.06%), utubari twipimisha twibasiwe n’ibice by’umusaruro, hamwe no gushushanya ibice byerekana uburebure.
Ibi ntabwo ari theoretical. Umwaka ushize, pompe yu Burayi OEM yaraduhinduye nyuma yuko abatanga ibicuruzwa bibiri babanje kunanirwa kurwego rwamazu ya silinderi ifite ibice 120 bya rukuta. Umucuruzi wabo wumwimerere yakoresheje ibumba ryumucanga hamwe nibisanzwe byibumba-bitera gukonjesha kutaringaniye hamwe na pearlite. Twahinduye resin ihujwe n'umusenyi hamwe no guhumeka neza hanyuma twongeramo imbaraga zo kugabanuka nyuma ya 580 ° C mumasaha 4. Igisubizo: kugoreka byagabanutse kuva kuri mm 0.18 kugera kuri mm 0,06 mm - muri zone yabo yihanganira CMM.
Niki "Uruganda rutaziguye" bivuze mubyukuri kubaguzi QT450-10
Bamwe mubatanga ibicuruzwa biyita "QT450-10 uruganda" kuko bafite uruganda. Abandi babona iryo zina kubera ko batunze urunigi rw'agaciro - kuva gushonga gushonga no guterera binyuze mu gusya-axis eshanu, kurasa, no gupima helium. Itandukaniro ryerekana mugihe cyo kuyobora, guhuza igishushanyo cyihuta, no gukemura imizi.
- Gutera-gutunganya imashini bibera mu nyubako imwe: Nta gutinda kwa logistique, nta byangiritse, nta gutumanaho nabi kubyerekeranye na datum.
- GD&T yemewe mbere yo gutunganya: Itsinda ryacu rya metrologiya risikana ibice byashizwemo ukoresheje urumuri rwerekana urumuri - kugereranya isura nyayo na CAD nominal kugirango uhindure inzira zikoreshwa muburyo butandukanye.
- Kuvura ubushyuhe birahujwe, ntabwo byatanzwe.
Uku kwishyira hamwe kugabanya impinduka za prototype kuva mubyumweru 12 kugeza kuri 5. Kubicuruzwa bito bito (500-5000 pcs / mwaka), bivanaho "icyuho cyubatswe" gihatira abaguzi kubika ububiko bwumutekano bwamezi 6. Umukiriya umwe wo muri Amerika ya ruguru yagabanije ibiciro byo gutwara ibicuruzwa ku gipimo cya 37% nyuma yo kwimukira mu ruganda rwacu rwa QT450-10.
Iyo QT450-10 idahagije-n'icyo gukora Ahubwo
Ba injeniyeri bamwe basanzwe kuri QT450-10 kubintu byose byuma byuma. Ariko turatanga inama ukundi iyo: ubushyuhe bwo gukora burenze 300 ° C (pearlite decomposition yihuta); kwambara birwanya ni ngombwa (urugero, piston impeta ya piston); cyangwa ruswa igaragaramo chloride cyangwa H₂S. Muri ibyo bihe, QT500-7 itanga imbaraga nyinshi ariko ihindagurika ryo hasi - cyangwa cobalt alloy T800 itanga 3 life ubuzima bwo kwambara kuri 650 ° C.
Dore ibyo dukora ahubwo: koresha ibikoresho triage mugihe cyo gusuzuma injeniyeri. Niba igice kibona> 200 MPa ihinduranya imihangayiko, twigana ubuzima bwumunaniro dukoresheje uburyo bwaho butoroshye muri nCode DesignLife. Niba ubukana bwubutaka bugomba kurenga HB 350, turasaba amanota yicyuma (ADI) amanota nka ASTM A897 Icyiciro cya 2. Niba geometrie ifite imbavu zoroshye (<8 mm) ikunda kugabanya ubukana, duhindukirira gushora imari, ndetse no mubyuma byangiza - kugirango twemeze neza.
Ibi ntabwo ari byiza. Irinda kunanirwa kumurima. Twanze amagambo 17 QT450-10 mumezi 18 ashize kuko gusaba byasabye ikindi. Icyizere gitangirira aho.
Guhitamo QT450-10 Mugenzi wawe: Amasheki atatu Atari Umushyikirano
Mbere yo gushyira umukono kuri NDA, baza ibibazo-usabe ibimenyetso:
- Urashobora kunyereka raporo eshatu zanyuma zisesengura kuri QT450-10? Ntabwo ari ibyemezo gusa - ibyasohotse byukuri hamwe na timestamp, indangamuntu ikora, hamwe na kalibibasi ya kalibibasi.
- Ukora ibizamini bya ultrasonic kuri casting zirenze mm 50? ASTM A609 Urwego rwa 3 nibisanzwe kubintu byingutu. Niba bavuga ngo "ubisabwe gusa," genda.
- Nubuhe buryo bubi-Cpk kubwimbaraga zingana kuri QT450-10 mumezi 12 ashize? Ikintu cyose kiri munsi ya 1.33 bisobanura guhungabana kwimibare. Ibyacu ni 1.68.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora uruganda rwa QT450-10 rwubatswe kubice byingenzi-ntabwo ari ibicuruzwa. Ntabwo tubitse ibintu rusange. Dutanga inteko zikora: igitutu cyumuvuduko hamwe nintebe zishyizwe hamwe, urufatiro rwa pompe hamwe nu mwobo wateganijwe mbere, imashini ya winch shaft hamwe ninzira nyabagendwa - byose biva kumasuka QT450-10. Ibyo byibandaho bidufasha kunonosora inzira abandi birengagiza: igenzura rya morphite ikoresheje inoculants zidasanzwe-isi, vibration ifashwa na degassing kugirango igabanye hydrogène, hamwe no kugenzura nodularity ukoresheje isesengura ryikora ryikora.
Intambwe ikurikira ntabwo isaba amagambo. Kohereza igishushanyo cyawe kubitekerezo byakozwe-nta mugozi ufatanije. Kuberako urunigi rwiza QT450-10 rutangira mbere yo gusuka kwambere.
