Iyo ba injeniyeri bagaragaje a ibyuma bifata uruganda, ntabwo bashakisha gusa ibyuma-bahitamo umufatanyabikorwa ushoboye kwihanganira kurenza ± 0.005 mm munsi ya 300-bar ya hydraulic imizigo, mugihe barwanya gutembera mumyanya ya cobalt-alloy. Uku nukuri kubikorwa inyuma ya buri cyuma cya valve inzu cyangwa piston pompe ya silinderi twe imashini kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Icyitonderwa gitangirira aho Clamping Force ihura na Geometrie
Ibikoresho byo gufunga ntabwo ari ibikoresho byunganira-ni umusingi ucecetse wo gusubiramo. Mu kigo cacu cyemewe na ISO muri Qingdao, twabonye imishinga myinshi ihagaze kubera ko ibikoresho byo hanze byahindutse mugihe cyo gusya byihuse byamazu ya AMS 5387 cobalt alloy amazu. Igisubizo? Gutandukana kwa mm 0,012 hejuru yubuso bukomeye - bihagije kugirango bitume amazi ava mumashanyarazi ya hydraulic yagenewe kugenzurwa na peteroli yo hanze.
Twubaka ibyuma byabugenewe bifata ibyuma gusa mugihe ibintu bitatu bihuye: icya mbere, igice cya geometrie gisaba kwifata-axis nyinshi (tekereza wapine winch center shaft rollers hamwe na flanges idasanzwe); icya kabiri, imyitwarire yibintu isaba kugenzura inzira yo kwagura ubushyuhe mugihe cyo kuvura ubushyuhe; icya gatatu, GD&T ihamagarwa harimo guhuza kwihanganira imyanya yerekana imibare myinshi icyarimwe.
Ibikoresho byacu bihuza ibyuma bikomye byuma, ibyuma byerekana ahantu hamwe na mm 0.002 zuzuye, hamwe na clamps ikora pneumatike yahinduwe kugeza kuri 12-18 kN imbaraga - zapimwe kumurongo, ntabwo byagereranijwe. Buri gishushanyo gikorerwa FEA kwemeza gutandukana mugihe gikabije cyo kugabanya imitwaro, hanyuma igenzurwa rya prototype ukoresheje scan ya CMM mbere yo kurekura umusaruro.
Impamvu Kwishyira hamwe bihindura imikorere yimikorere
Bamwe mubatanga isoko yohereza hanze, gutunganya, no kurangiza kubacuruzi batandukanye. Ntabwo. Mugihe ukeneye uruganda rukora ibyuma bifata ibyuma byunvikana byunvikana uburyo microstructure yicyuma cyumucanga kigira ingaruka kumyitozo ya biti mugihe cyo gutegura umwobo wa fixture - cyangwa uburyo T800 cobalt alloy akazi katoroshye akazi gahindura clamp-pad kwambara ubuzima - ukeneye gukomeza inzira.
Igice cyacu gihagaritse gitanga ibyiza byapimwe:
- Igipimo gihamye.
- Gukurikirana ibikoresho: Ibikoresho byose bitwara ibintu byinshi biva mububiko bubisi (byemejwe kuri ASTM A48 cyangwa AMS 5719) binyuze mugupima ubukana bwa nyuma
- Kwemeza imikorere.
Muminsi ishize twatanze sisitemu 14 yimikorere ya pompe yimodoka. Ryari rifite umwanya mu byerekezo 12,000 bitarinze gusubirwamo - kubera ko abaterankunga, imashini zashizwemo imashini, hamwe n’imiterere ikomye byose byakorwaga munsi y’igisenge kimwe, hamwe n’ibipimo bya metero.
Imipaka nyayo-yisi nuburyo dukora muri bo
Ba injeniyeri bamwe bibwira ko "precision" bisobanura gukomera kutagira umupaka. Ukuri gushiraho imipaka. Amavuta ya Cobalt-nikel atanga ubushyuhe bwihuse kuruta ibyuma byabikoresho mugihe cyo gusya. Niba igikoresho cyawe gikoresha amaboko asanzwe ya aluminiyumu, kwagura ubushyuhe byonyine birashobora guhindura igice cya 0.008 mm hagati yizuba-bihagije kugirango ukureho $ 2,400 AMS 5387 umubiri wa nozzle.
Ibi turabikemura duhuza coefficient yubushyuhe: imibiri ikoreshwa ikoresha ibyuma byangiza (CTE ≈ 11.5 µm / m · ° C), mugihe amakariso yo gufunga akoresha Invar 36 (CTE ≈ 1.2 µm / m · ° C) aho gufunga ibipimo bidashoboka. Ubuso burangije gukurikiza ibikenewe-ntabwo ari kataloge isanzwe: Ra 0.4 µm kumasura yabantu, Ra 1.6 µm kumurongo woguhuza kugirango uhuze gufata hamwe nigice cyo kugenzura.
Abakiriya bakunze kubaza bati: “Urashobora gufata mm 0.003 mm kuri diameter 300 mm?” Yego-niba igice cyibintu bigize ubutinganyi gishyigikiye, niba inkunga ya fixture irinda resonance kuri spindle RPM, kandi niba dusuzumye akarere koroherana hamwe no gupima optique * nyuma ya * gushiramo ubushyuhe. Ntabwo twigera dusezeranya ibyo physics itazemera.
Kurenga Ibice: Ubufatanye bwubuhanga mubikorwa
Uruganda rukora ibyuma rukora uruganda rutera ikizere atari iyo rwohereje agace - ariko iyo rufashe amakimbirane ya GD&T mbere yo gukata. Igihembwe gishize, itsinda ryacu ryubwubatsi ryashyize ahagaragara ibishushanyo mbonera bya datum ku gishushanyo mbonera cyamazu ya pompe. Umwanya wihariye wo kwihanganira werekanaga ubuso bwakorewe kure. Kongera guhindura ibice hafi ya * finale * datum yakijije umukiriya iminsi 11 na 18.500 $ muri casting zaciwe.
Twashizemo iki kibazo mubikorwa byose: gushushanya kwemeza hamwe nubuhanga bwa ASME Y14.5, ibitekerezo byakozwe mugihe cyamasaha 72, hamwe nigihe cyo kuvugurura mugihe cyo kugenzura ingingo ya mbere - atari nyuma yo gutanga PPAP. Abakiriya bacu muri Amerika ya Ruguru, Ubudage, na Singapuru bashingira kuri ibi - ntabwo ari inyongera ya serivisi, ahubwo ni uburyo bwo kugabanya ingaruka.
Niba umushinga wawe utaha usaba gukemura ibisubizo aho gusubiramo bihura nubwenge bwa metallurgjiya - aho igishushanyo mbonera gitangirana nimyitwarire yibintu, ntabwo ari uburyo bwa bolt - ukeneye umufatanyabikorwa ushingiye kubikorwa byukuri. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Yubaka ibyuma bifata ibyuma bifata ukuri, kuzenguruka nyuma yizunguruka, igice nyuma yigice.
