Iyo sisitemu ya hydraulic yananiwe munsi yumuvuduko wa 350-bar, cyangwa cobalt-alloy pump nozzle yamenetse nyuma yamasaha 472 yo gukora, ikibazo ntigikunze gutangira guterana. Iratangira kare - muguhitamo ibikoresho, gusobanura GD&T, cyangwa gukata kwambere kumashanyarazi menshi ya CNC. Niyo mpamvu abajenjeri bo muri Amerika ya Ruguru n'Uburayi badashaka gusa "serivisi zo gutunganya CNC." Bashakisha a uruganda rukora neza ifata ituze rinini nkigihe cyamasezerano-ntabwo ari icyifuzo.
Ntabwo amaduka yose yihanganira gufata superalloys kimwe
Twabibonye kabiri muri uyu mwaka: ingufu za Tier-1 zamazi ya OEM yakiriye amazu ya AMS 5387 cobalt alloy amazu afite agaciro ka Cpk hejuru ya 1.67 kumurambararo winyuma - ariko microcrake zo hejuru zagaragaye nyuma yubushyuhe bwamagare. Impamvu? Utanga isoko yakoresheje ibikoresho bisanzwe bya karbide adafite igihe nyacyo cyo kugenzura imitwaro yumuriro mugihe gikabije. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dukora imashini ishingiye kuri T800 dukoresheje kode ya PCD ikonjesha hamwe no kugenzura ibiryo byangiza. Ibiti byose byaciwe bizunguruka torque, umuvuduko ukonje, hamwe nibikoresho byo kwambara - amakuru ahujwe nibikorwa byimbere byimbere. Ibi ntabwo birenze ubuhanga. Nuburyo ufata mm 0.005 mm kuri 210-mm-ya diametre ya piston pompe ya silinderi mugihe ukomeje ubusugire bwa ASTM E112.
Ikigo cyacu cyujuje ISO muri Qingdao gikora kuringaniza no gutunganya akazi-ntabwo ari amaboko akurikirana. Ibyuma bikozwe mucyuma bigenda neza biva mu ziko bigabanya amashyanyarazi, hanyuma bikajya mu bigo bitunganyirizwa mu buryo butambitse. Nta kongera gushiraho. Nta guhuza sisitemu yo gusobanura. Nuburyo dutanga ibishingwe bya pompe bifite uburinganire buri munsi ya 0,012 mm kuri mm 1,200 - hanyuma tukabyohereza muminsi 18 yo gushushanya.
Kwishyira hamwe bihagaritse bivuze ko nta gukeka kubyerekeranye na metallurgie
Bamwe mubatanga isoko yohereza hanze, hanyuma bagura utubari mbisi mumashanyarazi. Dufatanya gutezimbere ibintu bifatika hamwe nababikora byemewe. Iyo umukiriya asabye cobalt-nikel icomeka kuri serivise ya gaz ikarishye, turagenzura ubushyuhe bwose burwanya ASTM A494 Grade CW6MC - ntabwo ari imbaraga zingana gusa, ahubwo irwanya ruswa hagati ya NACE MR0175 / ISO 15156 Umugereka A. Gukurikirana ibipapuro ntabwo ari agasanduku. Nibikoresho bya QR byanditseho ibyuma bisudira kuri buri kintu cyibanze, gihujwe na raporo zisesengura ryerekana, amateka yubushyuhe, hamwe namadosiye yanyuma ya CMM.
Iyi disipuline yerekana aho ifite akamaro kanini: imikorere ikora. Icyuma cya shitingi ya shitingi ikozwe muri 42CrMo4 isanzwe - yakozwe kugeza kwihanganira ISO 2768-mK, ikomekwa kuri 52 HRC, hanyuma ikagera kuri Ra 0.4 µm - yarokotse inzinguzingo 14.000 ku kizamini cy’ibizamini bya moteri idafite icyicaro. Ibice byabanywanyi byananiranye kuri cycle 8,920. Itandukaniro? Umurongo wo gutunganya ubushyuhe ukoresha itanura rigenzurwa nikirere gifite ± 2 ° C uburinganire, ntabwo ari amashyiga hamwe na gra 15 ° C.
Ibikorwa nyabyo-isi bitangira mbere yuko chip ya mbere iguruka
“Urashobora gukora ibi?” ni ikibazo kitari cyo. Igikwiye ni: “Ni iki kizacika mbere - kandi twabihagarika dute?” Mugihe cyo gusubiramo injeniyeri, dushyira ahagaragara guhamagarwa kwa GD&T bivuguruzanya nimbogamizi zifatika kumashanyarazi 5. Turasaba inama zinguni kumiterere yumucanga ugabanya gukuramo ibicuruzwa nyuma yimashini 37%. Turasaba ibikoresho bisimburana - nko guhinduranya ibyuma bitagira umwanda 1.4404 ukajya kuri duplex 1.4462 - mugihe chloride irenze 120 ppm.
- Twemeza gushushanya geometrie kurwanya inzira yo kugera kubikoresho - ntabwo ari ibipimo byizina gusa
- Twigana kugoreka ubushyuhe mumazu ya silinderi yoroheje dukoresheje SolidWorks Flow Simulation + coefficient zo kugabanuka.
- Turasubiza PDF zasobanuwe mumasaha 48-ntabwo ari rusange "imeri yemewe"
Nta prototype ijya mubyuma idafite raporo ya DFM yashyizweho umukono. Ntabwo ari ukubera ko dukunda impapuro. Kuberako gusimbuka bisaba amadolari 28,000 yo kongera gukora mugihe umubiri udasanzwe wa valve usaba ibintu bitatu bishya.
Kwizerwa ntabwo byasezeranijwe. Irapimwa, yinjiye, kandi yoherejwe
Ibicuruzwa byose birimo icyemezo cyujuje amakuru yuzuye ya metero: Ibicu bya CMM byerekana ibicu bikomeye, optique ya profili ya scan yo gufunga hejuru yikarita, amakarita akomeye kuri zone zivurwa nubushyuhe. Ntabwo tuvuga "guhura na spec." Twerekana * neza * aho 0.008 mm gutandukana byabaye-n'impamvu bidafite akamaro (urugero, hanze ya arc itwara igitutu).
Nuburyo dukomeza> 99.2% mugihe cyo gutanga ibicuruzwa byaciriritse-ndetse hamwe na 2024 ya titanium alloy itanga ihindagurika. Ibikorwa byacu bidafite ishingiro bikurikirana WIP kurwego rwa sitasiyo. Niba cobalt alloy nozzle ikubise icyuho cyo gusya, igenamigambi ry'umusaruro ritera inzira yikora kuri selile ya kabiri - nta kuzamuka gukenewe.
A uruganda rukora neza yizera ikizere atanyuze mu gatabo, ahubwo binyuze mubishobora kubaho mu murima: indangagaciro zumuvuduko ziracyafunze kumyaka 22, ibice bya pompe AMS 5387 bikorera kumurongo wa offshore hamwe na zeru zidateganijwe, ibice T800 bifite kwihanganira nyuma yubushyuhe 15. Ukwo guhuzagurika guturuka ku gufata buri gice nkaho kijya muri sisitemu igoye-kuko akenshi, ni.
Niba umushinga wawe utaha usaba sub-10-micron gusubiramo kubintu bigoye-kumashini-cyangwa niba umaze gukuraho ibyiciro bibiri bya prototype ukurikirana kubahiriza GD&T-tangira ukoresheje inzira iboneye, ntabwo ari ibiciro. Umufatanyabikorwa mwiza ntagabanya ibyuma gusa. Bakuraho uburyo bwo gutsindwa mbere yuko gahunda ishyirwaho.
