Iyo ba injeniyeri bagaragaje ikirere gishyiraho umucanga kubice byicyuma neza, ntabwo bahisemo uburyo bwumurage-bahitamo inzira yemejwe, ihamye murwego rwibigize bigomba kurokoka umuvuduko mwinshi, gusiganwa ku magare, no kwambara nabi. Bitandukanye n'umusenyi w'icyatsi cyangwa sisitemu yo gutekesha, gutondeka ikirere gishingiye ku butumburuke bwo mu kirere n'ubushyuhe bw’ibidukikije kugira ngo bikize binder - nta ziko, nta catisale, nta guhumeka ku gahato. Ubwo bworoherane bwerekana ubuhanga nyabwo bwa tekinike: kugera kuri mm 0.15 kwihanganira mm 300 ya cobalt alloy pompe amazu ntabwo ari "gukoresha umucanga gusa." Byerekeranye no kugenzura chimiya ya binder, guhuza ibishushanyo bisubirwamo, kugumana geometrike yibanze mugihe cyo kunyeganyega, hamwe na post-cast stabilisation mbere yo gukora.
Twashize hejuru ya 12,000 AMS 5387 cobalt alloy nozzles mumyaka itatu ishize - buriwese ufite ubugari bwurukuta munsi ya mm 4.2 hamwe nibice byimbere bisaba CMM yagenzuwe na GD&T. Muri buri cyiciro, uburyo bwo gushyiraho ikirere bwatanze imbaraga nke zisigaye kurenza ubundi buryo bwo guhuza imiyoboro, kugabanya kugoreka nyuma yimashini 37% kumazu ya pompe ya pompe. Ibyo ntabwo ari theoretical. Irapimirwa kuri Zeiss CONTURA G2 ya mashini yo gupima imashini, yanditswe kuri buri gice, ikurikiranwa nimibare yubushyuhe bwibikoresho hamwe nindangamuntu.
Kuki iki kibazo? Kuberako ikirere cyashyizwe kumucanga ntabwo ari ugusubira inyuma-ni ugushoboza ingamba za geometrike zingenzi aho uburinganire bwa microstructure hamwe no guhanura ibipimo biruta umuvuduko muke. Tekereza umubiri wa hydraulic umuvuduko wumubiri: wakozwe mubyuma bidafite ingese, bisaba amasaha 18 yo gusya-axis nyinshi kandi bigatanga 62% imyanda. Binyuze mu mucanga washyizwe mu kirere, imiterere ya net igera hafi ya 92% ya misa ya nyuma idahwitse, ntoya imbere (ASTM E155 Urwego rwa 2), hamwe na dendritic intera imwe yemejwe na metallographic cross-section. Igisubizo? Igiciro gito, igihe gito cyo kuyobora, kandi-cyane cyane - kurwanya umunaniro mwiza kurwego rwumuvuduko uri hejuru ya 420.
- Ubudahemuka. Ibyo birinda amadirishya akomeye ya chimie asabwa kuri T800 ya cobalt ashingiye ku mavuta - aho ndetse na 0,03% birenze urugero bya karubone byangiza ubukana.
- Gushikama: Nta reaction ya exothermic bivuze ko nta shitingi yumuriro yibumba mugihe cyo gusuka. Dusanzwe dusuka 1100 ° C ya cobalt-nikel yashongeshejwe mubibumbano bifashe kuri 22-28 ° C ibidukikije - nta gihu, nta gutembera hejuru.
- Guhuza ibipimo: Kwagura ibishushanyo birahanurwa kandi birasa. Kuri moteri yimodoka ya winch center ya shitingi (OD 215 mm, uburebure bwa mm 480), dufata uburinganire muri mm 0,08 hejuru yubufindo 100-nta kugabanya ibibazo bya kabiri.
Bamwe bashobora kuvuga ko umuyaga washyizweho umuyaga udafite ubuso bwo kurangiza gushora imari. Nukuri - ariko uburinganire bwubuso Ra 6.3 µm burahagije muburyo bwo guhuza ibikorwa kumikorere ya pompe na valve manifolds. Aho kurangiza ibintu, duhuza neza CNC ihinduka * nyuma yo gukina - ntabwo mbere. Urwo ruhererekane rwirinda gutunganya ibintu bitagabanije kugabanuka. Twirinda kandi umutego usanzwe wo kwerekana imbaraga zirenze urugero: silikatike ya sodium nyinshi yongerera ububobere hamwe ningaruka zo kumeneka mugihe cyo gukemura. Uburyo bwiza bwacu bukoresha 3.8% binder kuburemere, yakize iminota 45 kuri 55% RH-yemejwe mugihe cyibihe bitatu mubushuhe bwa Qingdao.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yacu uruganda rushyira umucanga uruganda ikora nk'urufatiro rumwe mu kazi gahujwe cyane-ntabwo ari akayaga gashinzwe. Iyo umukiriya atanze igishushanyo cya plaque idasanzwe ya cobalt, inzira yacu itangirana no gusuzuma ibyuma: AMS 5387 ni urwego rukwiye - cyangwa yahinduye T800 itanga uburyo bwiza bwo guhangana na serivisi zamazi yumunyu? Noneho haza kwigana ibishushanyo mbonera: Sisitemu yo gukingira izagaburira igice cyoroshye cyane mbere yuko uruhu rukonja? Gusa noneho twubaka imiterere, kuvanga umucanga, no gusuka. Intambwe yose igaburira amakuru muri ISO 9001 yemewe-yujuje ubuziranenge-ibikoresho byinjira, utubari twinshi twapimwe kuri ASTM A781, ubugenzuzi bwa ultrasonic bwakorewe ku nkuta zose> mm 25 z'ubugari.
Uku kwishyira hamwe gutanga ibyo abaguzi bakeneye mubyukuri: ibice bihuye, imikorere, nibya nyuma - ntabwo ibice byohereza gusa. Kubikoresho bya peteroli yo muri Amerika ya ruguru OEMs, bivuze ko indangagaciro zumuvuduko zirokoka 12,000 kuri 350 ° F nta kumeneka. Kububaka ibinyabiziga byuburayi byuburayi, bivuze imashini ya winch shaft ikomeza kwibanda nyuma yamasaha 500 yo gutwara amagare. Kubateranya pompe yamajyepfo yuburasirazuba bwa Aziya, bivuze inzu ya silinderi igera hamwe na datum yimashini isanzwe iri muri mm 0,05 mm - yiteguye guterana kwanyuma, ntabwo yongeye gukora.
Niba urimo gusuzuma abatanga ibicuruzwa byuzuye, baza ibibazo bitatu: Bashobora kwerekana raporo ya CMM kuri geometrie yawe yihariye - ntabwo ari rusange? Baragenzura kuvanga kuvanga, gukiza ibishushanyo, hamwe no kunyeganyeza mugihe nyacyo - cyangwa bashingiye kuburambe bwabakozi wenyine? Kandi bahuza ibikorwa byo gutoranya amakuru kubikorwa byanyuma mugukoresha imirima? Ku kigo cyacu, igisubizo kuri ibyo uko ari bitatu ni yego - kandi byanditswe muri buri gitabo cyakozwe. Precision ntabwo igerwaho murwego rwo gutunganya. Bitangirira mu mucanga.
