Iyo ba injeniyeri bagaragaje a uruziga shaft roller uruganda, ntabwo batumiza igice gusa-barinda umugongo wo kuzenguruka kumurongo muremure wibyuma. Twabonye ibicuruzwa byinshi bihagarara biterwa na shitingi yazengurutse nyuma ya metero 3.000 yo kugaburira ibishishwa bikomeza, cyangwa kunanirwa kugenzura hejuru kuri 58 HRC. Niyo mpamvu ibisobanuro bidashoboka hano-ni ishingiro.
Impamvu Shaft Rollers Yatsinzwe-Kandi Mubyukuri Bikora
Kunanirwa kwinshi gushingiye kumpamvu eshatu: imiterere ya metallurgjique idahuye, gutembera kurwego mugihe cyamagare yubushyuhe, hamwe nuburinganire bwubuso budahagije mugihe cyo guhura nabi. Ibyuma bya karubone bisanzwe byacitse munsi yimyunvire ihindagurika. Amavuta avanze adafite ingano yatunganijwe ateza imbere micro-crack hafi yinzira nyabagendwa. Kandi abasimbuye CNC basimbuye akenshi basiba kugabanuka nyuma yimashini - bityo bakagoreka mumasaha 48 yo kwishyiriraho.
Turagerageza buri shitingi ya shaft kugirango ikomere kuri torsional dukoresheje protocole ya ASTM E143 - kandi twanze igice icyo aricyo cyose cyerekana> 0,012 mm ya radiyo yiruka kuri 3000 rpm. Iyemezwa-ryukuri rifite agaciro kuruta kataloge. Uruganda rumwe rwo muri Amerika ya ruguru rwatangaje ko ubuzima bwa serivisi bumaze 47% nyuma yo kuva muri rusange AISI 4140 ikajya muri AMS 5387 cobalt-nikel alloy rollers, nubwo iyanyuma yaguze 2,3 × hejuru. ROI yavuye mugukuraho ibyasimbuwe buri cyumweru no kwirinda igihe cyateganijwe mugihe cyogukora imiyoboro yimodoka.
Kwishyira hamwe guhagaritse gukemura ibyo Outsourcing idashobora
Ntushobora gutanga amabwiriza yo kugenzura ibyuma. Iyo umukiriya yohereje igishushanyo cya GD&T kuri mm 215 mm OD × 1,850 mm z'uburebure bwa shitingi ya shitingi ya shitingi - hamwe na ± 0.005 mm silindrike, ubukana bwa HRC 62-65, hamwe nubushakashatsi bwuzuye kuri MTRs - ukeneye guta, gutunganya, no kuvura ubushyuhe munsi yinzu imwe. Nta ntoki. Nta cyiciro kidahuye.
Ikigo cyacu cyujuje ISO gikemura ibyo uko ari bitatu:
- Gutera umucanga y'ibyuma byangirika hamwe n'ibyuma bidafite ingese hamwe nigipimo cyo gukonjesha kigenzurwa kugirango wirinde nodular grafite
- Multi-axis CNC ihinduka no gusya ya shitingi ikomye-ukoresheje inzira-ya CMM igenzura nyuma yo gukomera, kurangiza, na pass ya nyuma
- Binyuze-gukomera + induction hejuru gukomera, byemejwe na Rockwell C-igipimo cyambukiranya buri mm 150 muburebure
Ibi bivanaho icyiciro cya "fondasiyo-ku-mashini-iduka": aho kugabanuka kwa casting bitabarirwa mu gutunganya amafaranga yimigabane, cyangwa aho ubushyuhe bwo kuvura kugoreka butesha agaciro ibipimo byabanjirije kurangiza. Twagabanije kongera gukora kuri 68% kuva twashyira mubikorwa indishyi zifunze zumuriro muri gahunda zacu za CNC.
Guhitamo Ibikoresho ntabwo imyitozo yihariye y'urupapuro
"Ibyuma bitagira umuyonga" ntacyo bivuze bidafite imiterere. Kubantu bazunguruka bakora ibyuma bisizwe cyangwa bisize ibyuma, 304SS yambara mumasaha 800. Imashini yacu ya T800 ishingiye kuri cobalt imara amasaha arenga 5.200 - kubera ko ikwirakwizwa rya karbide ryanga kurigata, ntabwo ari ruswa gusa. Kandi AMS 5387 ntabwo ari "cobalt alloy" gusa - ni sisitemu yuzuye ya Co-Ni-Cr-Mo-W yashizweho kugirango igumane ubukonje burenze hejuru ya 600 ° C, birakomeye mugihe ubushyuhe bwo gushyuha bwihuta mugihe cyo kwihuta.
Dutanga inkomoko mbisi gusa kuva murusyo rwemejwe na AMS 2301 na EN 10204 3.1, hamwe nubushyuhe bwuzuye. Buri cyiciro gikora isesengura ryerekana mbere yo gukina - kandi tugumana ingero kumyaka 10. Niba umukiriya avuga kwambara imburagihe, dukurura MTR yumwimerere, tukayigereranya na microstructure igice nyacyo (binyuze kuri SEM / EDS), hanyuma tugatandukanya niba ikibazo cyari ibintu, inzira, cyangwa porogaramu idahuye.
Kwizerwa bitangira mbere yo gukata bwa mbere
Yizewe uruziga shaft roller uruganda ntategereza ko ibishushanyo bigera. Ikora hakiri kare - mugusubiramo ibishushanyo. Dukunze gushyira ibendera kubibazo nka radiyo idafite umurongo wa radiyo yibanda ku guhangayikishwa no kwicara, cyangwa kwihanganira inzira zidasanzwe zitera kwambara. Umwaka ushize, twafashije OEM yo mu majyepfo yuburasirazuba bwa Aziya OEM kuvugurura urutugu rwa geometrie kumurongo wa 12 uhinduranya-kugabanya impagarara ya von Misesa 31% no kongera umunaniro kurenza 107 inzinguzingu.
Gutanga ituze bikomoka ku igenamigambi rishingiye ku ntego - ntabwo ari amasezerano. Dukurikirana ibintu bisuka, ubushyuhe bwo kuvura imizigo, na gahunda ya mashini mumasaha 4. Prototype itumiza ubwato muminsi 18; urwego ruciriritse rwiruka rufata ± 2-iminsi-Windows. Ntamafaranga yihuse. Nta "ukurikije ibintu biboneka". Kuberako kwizerwa bitareba gusa ibizunguruka ukuri-bijyanye nibigera mugihe, buri gihe.
Kuri ba injeniyeri bagaragaza ibice aho gutsindwa bihagarika imirongo yumusaruro, guhitamo ntabwo biri hagati yabacuruzi-ni hagati yibitekerezo nibimenyetso. Ibikoresho bya shaft byuzuye bisaba ubufatanye bwuzuye. Ibyo bitangirana na metallurgie urashobora kugenzura, inzira ushobora kugenzura, nibisubizo ushobora gupima - atari muri micron gusa, ariko mugihe cyo hejuru.
