Iyo inzu yawe ya hydraulic ya valve igomba kuba ifite kwihanganira mm 0,02 mm munsi ya 350 bar pulsation - cyangwa cobalt alloy pump nozzle ikomeza amasaha 8000 muri serivisi ya gaze ikarishye - ntabwo utumiza gusa. Urimo wujuje ibisabwa a uruganda rukora neza nkukwagura tekinike yikipe yawe yubuhanga.
Twabonye imishinga myinshi ihagaze kumuryango wubatswe: gutembera kugipimo nyuma yo kuvura ubushyuhe, kugabanuka-micro mu bice bikikijwe na AMS 5387, guhamagarwa kwa GD&T byasobanuwe nabi nk "intera yemewe" aho kuba imipaka ikomeye. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri casting nkibigize imikorere - ntabwo ari ubusa kugirango ikorwe nyuma. Ibyo bivuze kugenzura metallurgie * mbere yo gusuka, kugenzura imiterere yingano * nyuma yo gukomera, no gufunga geometrie * mugihe * CNC yarangije - byose munsi yinzu imwe yemewe na ISO i Qingdao.
Kuki kwihanganira gutora bitangira kera mbere yuko ifunga rifunga
Kunanirwa kwinshi kunanirwa gusubira inyuma kubintu bitatu byakwirindwa: kudahuza ibintu, gucamo ibice, hamwe namakosa yo mu ntoki. Turabafunga nkana.
Ubwa mbere, kugenzura ibikoresho fatizo ntabwo bijyanye na seritifika - ni ibyiciro-urwego rwo gukurikiranwa kugeza kumashanyarazi. Iyo ugaragaje T800 ya cobalt ishingiye ku mavuta, dukomoka kubatanze ibyangombwa byambere batanga raporo yuzuye ya ecran * na * amateka yubushyuhe bwamakuru kuri buri kintu cyinshi. Nta chimie "isanzwe". Nta "as-cast". Isuka yose isuzumwa na AMS 5387 yumutungo wubukorikori - ntabwo ari imbaraga zingana gusa, ahubwo kurambura kumeneka no gukomera bikabije mubice byubugari.
Icya kabiri, guhuza vertical bikuraho kwihanganira stack-up yica ibice-byuzuye. Gutera umucanga byonyine ntibishobora gufata mm 0,15 mm kumazu ya mm 400. Ariko iyo itsinda ryacu ryashinzwe rifatanya gukora sisitemu yo kwinjiza hamwe nabashinzwe imashini - kandi amakipe yombi asubiramo raporo imwe ya CMM kumiterere yumucanga wicyatsi - dukuraho imirongo yo gukora. Umurongo wo gushora imari ukora ibice byimbere byimbere mumashanyarazi; umurongo wumucanga utanga urufatiro runini rwa pompe rugera kuri kg 1,200 - byombi bigaburira mu ngirabuzimafatizo eshanu za CNC aho imyanda ya nyuma, hejuru yikimenyetso, hamwe nisura yimbere ikorerwa muburyo bumwe.
Icya gatatu, ubugenzuzi ntabwo ari igenzura-ni ugukomeza kwemeza. Ibikoresho byinjira bibona spark spectrometry hamwe na ultrasonic test. Igenzura-ryimikorere ukoreshe Zeiss CMMs hamwe na kalibibasi ya progaramu ya datum zikomeye, wongeyeho igereranya rya optique kubintu byihariye byerekana imiterere nka nozzle orifices. Igenzura rya nyuma ririmo igeragezwa ryimikorere (kugeza kuri 500 bar), irangi ryinjira mubitaka byo munsi y'ubutaka, hamwe no kugenzura ububobere bwo hejuru kuri ISO 4287 - byanditswe muri dosiye yuzuye ikurikirana ihujwe nimibare ikurikirana.
Aho ibishingwe bisanzwe bihagarara, gutora neza biratangira
Bamwe bashobora kuvuga bati: “Imashini ya CNC itanga kwihanganira cyane kuruta gukina - none se kuki utera?” Byemewe - ariko ntibyuzuye. Gukora pompe ya pisitori 300 mm ivuye mubyuma bidafite ingese 78% byibikoresho fatizo, bitera guhangayika, kandi bishobora kugoreka mugihe cyo kuvura ubushyuhe. Gutera hafi ya net-net hanyuma ukarangiza gusa ibintu bigoye bigabanya umwanya uyobora 40%, bigabanya itandukaniro ryibiro hagati yitsinda, kandi bikarinda ingano yerekana ingano kugirango irwanye umunaniro.
Itandukaniro nyaryo? Gukemura ibyo abandi banze. Amavuta ya Cobalt-nikel nka AMS 5387 ntabwo bigoye gukora imashini-gusa ntabwo bihagaze neza. Ubushyuhe bukabije mugihe cyo gusya? Intete ya okiside yangiza yangiza ruswa. Undercool yihuta cyane muri casting? Micro-porosity ikora mubyimbye-byoroheje. Dukoresha porogaramu yo kwigana amashyuza kuri buri gice gishya cya geometrie, duhindura igipimo cyo gukonjesha mugihe nyacyo dukoresheje thermocouples yashyizwemo, kandi twemeza microstructure hamwe na metallografiya yambukiranya ibice - atari ku ngingo za mbere gusa, ariko buri gihembwe kuri tombora.
Ibice byinshi dusabwa birabigaragaza: inzu ya piston pompe ya silinderi hamwe nibitekerezo <0,03 mm hejuru ya mm 600 z'uburebure; winch center shaft umuzingo hamwe na zone zambara zidahuye zihura na ASTM A957 Icyiciro cya 100 cyihariye; Amacomeka ya cobalt adasanzwe hamwe na kashe ebyiri-zingana zisaba ± 0.015 mm z'ubugari na Ra 0.4 μm kurangiza. Ibi ntabwo ari ibintu bya catalog. Nibisubizo byubushakashatsi-aho ibipimo byo guta, uburyo bwo kuvura ubushyuhe, hamwe ningamba zo gutunganya bifatanyirizwa hamwe kuva kumunsi wambere.
Nigute ushobora kugenzura uruganda rukora neza
Baza ibi bibazo bitatu - urebe uko bisubiza:
- "Nyereka raporo zawe eshatu za nyuma za CMM ku gice gifite umuhamagaro wa GD&T urenze mm 0,05 mm." Niba bashidikanya, cyangwa bagabana inyandikorugero rusange, genda. Amaduka nyayo abika ububiko bwuzuye bwa digitale.
- "Nigute ushobora kugenzura kugabanuka kurukuta rwa mm 12 yegeranye na shobuja 45 mm?" Ibisubizo bidasobanutse kubyerekeye "igishushanyo mbonera" ibimenyetso byo gukeka. Amaduka adasobanutse yerekana umusaruro ushimishije wo kwerekana ubushyuhe no kwerekana delta yapimwe hagati ya cast-na nyuma ya HT.
- "Ni ikihe gipimo cyo kwangwa kuri AMS 5387 yakinnye mu mezi 12 ashize - kandi niyihe ntandaro yo gutsindwa bitatu bya mbere?" Gukorera mu mucyo hano bitandukanya abafatanyabikorwa n'abacuruzi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Itangaza buri mwaka ubuziranenge bwimbere imbere - kandi igabana ibipimo bijyanye nabafatanyabikorwa babishoboye babisabwe. Ikigereranyo cyo kugereranya ibipimo ngenderwaho byokworoherana cyane bihagaze kuri 99,73%, hamwe no gutandukana bijyanye no kugabanuka bingana na 0.8% byibitagenda neza - bivuye kuri 2,1% mumyaka ibiri ishize nyuma yo kuzamura sisitemu yo kugenzura ubushyuhe bwubushyuhe.
Ibice byihanganirwa cyane ibyuma ntibisohoka mubishushanyo byiza. Ziva mubyago bisangiwe, inzira zanditse, hamwe no kudahwema kwitondera ibiba hagati yisuka yashongeshejwe no gukoraho kwa nyuma kwa CMM. A. uruganda rukora neza ntibisobanuwe nibikoresho byayo-bisobanurwa nuburyo bihuza cyane disipuline ya metallurgical hamwe na geometrike yizewe. Ngiyo amahame twubaka. Isuka yose. Igice cyose. Igihe cyose.
