Iyo hydraulic valve yawe yananiwe kuri psi 3000 - cyangwa pompe ya cobalt-alloy pompe yamenetse munsi yumukino wogukoresha ubushyuhe - ntukeneye gukora "byiza bihagije". Ukeneye guhagarara neza muri ± 0.005 mm, uburinganire bwa microstructure hejuru yubushyuhe butunganijwe na AMS 5387, hamwe no kwihanganira zeru kubintu bitagaragara. Niyo mpamvu abajenjeri muri Amerika ya ruguru, Ubudage, na Singapore bagaragaza ibice kuva a uruganda rukora neza rwa CNC ifata GD&T ntabwo ari impapuro-ahubwo ni fiziki idashobora kuganirwaho.
Ukuri-kwisi gutangirira aho kwihanganira kureka kuba theoretical
Twabibonye kabiri muri uyu mwaka: Tier-1 itanga ibikoresho bya peteroli yo mu cyiciro cya 1 yanze 47% byamazu ya prototype piston pompe ya silinderi yabacuruzi batatu batandukanye - ntabwo ari ukurangiza hejuru, ariko kubera ko kwibanda kwa bore kwagiye hejuru ya mm 0.012 nyuma yo kuvura ubushyuhe. Intandaro? Imiterere idahwitse yo gutera ingano igaburira ibikorwa bya CNC. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Turabikemura hejuru. Uruganda rwacu rwo guta umucanga rugenzura igipimo cyo gukomera kwicyuma nicyuma kitarimo ibyuma ukoresheje ikarita yerekana ikarita-nyayo-hanyuma ugenzure buri fagitire yinjira hamwe nisesengura ryerekana mbere yuko imashini itangira. Nta bitekerezo. Nta cyiciro kidasanzwe.
Uku guhuza vertical-casting, axis-axis CNC, kuvura ubushyuhe, hamwe no kurangiza hejuru yumusenge umwe wujuje ISO - bivuze ko twihanganira geometrike * tunyuze kumurongo wuzuye. Umubiri wumuvuduko wumuriro ntabwo wakozwe gusa gushushanya; kugabanuka kwayo kwakorewe icyitegererezo, kugoreka kwayo nyuma yimashini yapimwe kuri Zeiss CMM, nubukomezi bwayo bwa nyuma bwemejwe na ASTM E18. Dutanga ibice bikomeza kubaho - ntabwo byatsinze gusa - ikizamini cya mbere cyumuvuduko.
Superalloys ntabwo "bigoye gukora imashini." Bayobowe nabi
Abaguzi bamwe bafata amavuta ya cobalt-nikel nkicyuma gikomeye. Ntabwo aribyo. Ibice bishingiye kuri T800 bisaba ingamba zuburyo bugabanya ubushyuhe bwiyongera - ntabwo ari ibiryo bikabije. Twifashisha gusya cyane hamwe na PCD yometse kuri PC ya AMS 5387, tugumana ubusugire bwubutaka munsi ya Ra 0.4 µm mugihe dufashe uburebure bwurukuta kugeza kuri mm 0.008. Kuki iki kibazo? Kuberako itandukaniro rya 0,015-mm muri cobalt alloy plug ihindura coefficient ya 11% mumashanyarazi ya hydraulic yumuvuduko mwinshi-kandi ibyo birashobora gupimwa kunanirwa mumirima.
Igorofa yacu ikora imashini eshanu-DMG MORI NT imashini zikurikirana hamwe nubushakashatsi bwakozwe, ariko itandukaniro nyaryo ni disipuline. Dufatanya guteza imbere uburyo bwo kuvura ubushyuhe hamwe n’ibikoresho byemewe bitanga ibikoresho - tukareba ko buri cyiciro cya AMS 5387 gikubita intego yo gukomera (MP1,380 MPa) no kuramba (≥12%) * mbere yuko * gukata bitangira. Mugihe umukiriya yadusabye kwigana T800 alloy center shaft roller ya sisitemu ya winch yimodoka, twahinduye injeniyeri ya microstructure yambere dukoresheje isesengura rya SEM / EDS - ntabwo twakoporora gusa. Igice cyakoresheje 32% muri serivisi kuruta gusimbuza OEM.
Kwizerwa ntabwo byasezeranijwe. Yubatswe muri protocole yo kugenzura
"Full traceability" bisobanura ibirenze umubare washyizweho kashe kumasanduku. Kuri buri kintu cyingenzi - ibyuma byumuvuduko, urufatiro rwa pompe, amazu ya silinderi - twandika: raporo yikizamini cyibikoresho fatizo, ibisubizo bya X-ray, indangamuntu ya porogaramu ya CNC, amadosiye yo gupima CMM, imbonerahamwe yerekana itanura, hamwe n’inyandiko zerekana ubugenzuzi bwa nyuma. Amakuru yose abikwa kumyaka 10. Abakiriya bagera ku mateka yumushinga babinyujije kumurongo wizewe - ntabwo ari PDF zoherejwe mu gicuku.
Ariko kugenzura bibaho * mugihe cyo gukora - ntabwo birangiye gusa. Abakoresha bakora igenzura-bakoresheje igereranya rya optique kubintu nka nozzle orifice geometrie. Igice cya gatatu kinyura muri CMM yuzuye igenzura dosiye yumwimerere - ntabwo ari ibipimo byingenzi. Kandi yego - twemeza GD&T guhamagarwa nkumwanya, umwirondoro, hamwe na runout * murwego *, ntabwo nkibintu byihariye. Niba igishushanyo cyawe kigaragaza kwihanganira imyanya ihuza isura ya flange ugereranije na bore axis, turabipima gutya - dukoresheje simulator ya datum yigana imiterere nyayo.
Ingengabihe yawe ntigomba guterwa no gutegura ubushobozi bwabatanga
Ibicuruzwa biciriritse (50-500 pcs) akenshi bihagarara ku nganda zitezimbere kuri prototypes cyangwa umusaruro mwinshi. Twubatsemo akazi kacu kubutaka bwo hagati: imiterere y'utugingo ngengabuzima, imiterere isanzwe y'imiryango igizwe na pompe, hamwe na buffer yibikoresho bya cobalt hamwe n amanota adafite umwanda. Iyo pompe yu Burayi OEM yari ikeneye ibice 120 bya pompe AMS 5387 muminsi 18 - nyuma yuko abadandaza babo babuze igihe ntarengwa cyiminsi 37 - twatanze kumunsi wa 17. Ntabwo twakoresheje weekend. Mugukuraho ibikorerwa kumurimo: guta poritike byafashwe mbere yo gutunganya, kwambara ibikoresho bikurikiranwa mugihe nyacyo, nubugenzuzi bwa nyuma bwarangiye mbere yo gupakira.
Ibyo kwizerwa bigera no kumfashanyo yubuhanga. Ntabwo dusubiramo ibishushanyo gusa - dushyira ahagaragara ibendera rishobora gukorwa * mbere yo kuvuga: "Uru rukuta rwa mm 0.3 ku nzu ya valve ruzahinduka mugihe cyo gufunga; tekereza kongeramo imbavu z'agateganyo." Cyangwa: "Kugaragaza Ra 0.2 µm kurangiza bisaba amashanyarazi - ntabwo gusya - byongera iminsi 3 ariko bikabuza gutangiza micro-crack." Ntibitangaje. Gusa ibyemezo byashingiweho mumyaka 12 yo gutunganya ibice byinshi byinganda.
Kubice byibyuma byingenzi-aho gutsindwa bisobanura igihe cyo gutinda, ibyago byumutekano, cyangwa garanti ya garanti - ibisobanuro ntabwo ari urupapuro rwabigenewe. Nuburyo ugenzura imiterere yintete, ukayobora kugoreka ubushyuhe, kandi ugashyira mubikorwa uburinganire buringaniye muri casting, gutunganya, no kurangiza. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora nka a uruganda rukora neza rwa CNC kuberako ifata buri micron nkibisabwa bikora-ntabwo ari intego. Igice cyawe gikurikiraho ntigikeneye irindi jambo. Irakeneye umufatanyabikorwa upima intsinzi mugihe gikora, ntabwo ari mugihe cyo gutanga gusa.
