Iyo abajenjeri bagaragaje ibyuma bidafite ingese kubice bisobanutse neza, byingenzi-ubutumwa-tekereza indangagaciro zumuvuduko muri sisitemu ya hydraulic cyangwa inzu ya silinderi ya pompe ya piston - bakeneye ibirenze kurwanya ruswa. Bakeneye ituze ryikigereranyo munsi yubushyuhe bwumuriro, ubunyangamugayo bwa microstructural nyuma yo gucumura, hamwe nubuso burangiye burokoka itangazamakuru ryangiza. Aho niho abiyeguriye guterwa ibyuma bikozwe mu ruganda ahinduka kutaganira-ntabwo ari uwabitanze, ahubwo nkumufatanyabikorwa.
Impamvu MIM idafite ibyuma isaba kwishyira hamwe-Ntabwo ari ibikoresho gusa
Twabonye imishinga myinshi ihagaze kuri prototype kuberako iduka rya MIM ryakoraga kuvanga amatungo no kuvanga, ariko gusohora hanze gucumura kubakoresha itanura rusange. Ibyuma bitagira umuyonga nka 17-4 PH cyangwa 316L bitwara bitateganijwe nta kugenzura neza umuvuduko wa ogisijeni igice, igipimo cyinshi, no gufata ibihe mugihe cyo gucumura. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Nta ntoki. Nta gihinduka-cy-icyiciro cyo gukura kwimbuto. Ntibitangaje mugihe umuhamagaro wa GD&T usaba mm 0,02 mm kubintu bito bito bikikijwe na mm 1,2 z'ubugari.
Kwishyira hamwe bifite akamaro cyane iyo geometrie ihuye nibikorwa. Icyuma cya shitingi ya shitingi yimodoka yubukorikori ikenera ubukana ≥38 HRC * na * hejuru yubuso bwa Ra ≤0.8 µm - ibisabwa bihatira ubucuruzi hagati yubucucike bwimashini no gukora nyuma ya MIM. Ikigo cyacu gikemura icyo cyuho: turacumura hafi-net-shusho, hanyuma dushyireho imirongo myinshi CNC irangiza hamwe no kuvura ubushyuhe bwuzuye - nta bikoresho byo hanze, nta makosa yongeye kubaho, nta gutakaza gukomeza datum.
Aho MIM isanzwe yananiwe - nuburyo ibikoresho-byihariye ubuhanga bukosora
Bamwe bashobora kuvuga ko uwatanze MIM ashobora gutunganya ibyuma bidafite ingese niba bakurikiza ASTM F2885. Ariko uburyo-bwo kunanirwa kwisi buravuga inkuru itandukanye. Twakurikiranye inshuro nyinshi zacitse mu ntebe za valve 316L dusubira kuri karuboni isigaye ya karuboni isigaye ku mbibi z’ingano - inenge itagaragara mu igenzura rya optique ariko ibiza biterwa n'umuvuduko ukabije. Gukosora ntibyari byihuse; yarimo ihinduranya kuva paraffin ishingiye kuri polyacetal ishingiye kuri binders * no * kongeramo ikirere cyagenzuwe mbere ya sinter soak intambwe. Iri hindurwa ryaturutse kumyaka 12 ikora AMS 5387 cobalt alloy nozzles - ibikoresho bifite sensibilité yo kwagura amashyanyarazi ariko ibihano bihenze kubisigazwa.
Ubunararibonye bwimura ibyuma bitagira umwanda. Metallurgiste yacu ntabwo bafata 17-4 PH nk "ikindi cyiciro gusa." Bazi ko gusaza kwayo guhinduka niba ubushyuhe bugabanutse ± 5 ° C. Bagenzura buri fu yinjira hamwe nisesengura rya OES - ntabwo ari Fe / Cr / Ni gusa, ahubwo no kuri ogisijeni na azote bigenga morfologiya. Kandi bandika buri kintu cyose: ikime mucyumba cyo gucumura, umuvuduko wumukandara mu ziko ryangirika, ndetse nubushuhe bwibidukikije mugihe cyo gutunganya icyatsi. Kuberako mumateraniro yumuvuduko mwinshi wa pompe, itandukaniro rya 0,3% ntabwo ari theoretical-ni kunanirwa umunaniro imburagihe kuri 12,000 psi.
Kuva Gushushanya kugeza Gutanga: Niki "High-Precision" Mubyukuri bivuze mubikorwa
"High-precision" ikoreshwa nabi buri gihe. Ibisobanuro nyabyo bisobanura gusubiramo ibice 500+, ntabwo ari CMM imwe gusa. Bisobanura gufata umwanya nyawo kuri Ø3.2 mm umwobo uri hagati ya mm 42 hagati ya 0,015 mm - * nyuma yo kugabanuka, gucumura, * nyuma yo kugabanuka, * nyuma ya passivation. Dore uko tuyitanga:
- Igenzura ryinjira: Ifu y'icyuma idafite ingese yageragejwe kugirango igabanye ingano (D50 ≤ 8.5 µm), ubucucike bugaragara, n'umuvuduko ukabije kuri ASTM B212
- Kugenzura inzira: Ibiro by'icyatsi kibisi byinjiye kuri buri cyuho; Ubucucike bwacumuye bupimwe hakoreshejwe uburyo bwa Archimedes kuri mbere-na buri gice cya 50
- Iyemezwa rya nyuma: 100% ubugenzuzi bwa CMM kuri datum zikomeye; guhitamo SEM / EDS hejuru yimiterere yo gusesengura pore
- Gukurikirana: Buri tombora itwara QR-code yerekana ihuza ifu, gucumura indangamuntu, logi ya operateri, na raporo yubugenzuzi bwa nyuma
Ibi ntabwo birenze urugero-ni ishingiro ryabakiriya muri peteroli na gaze bakeneye ASME B31.4 kubahiriza cyangwa EU PED 2014/68 / EU ibyangombwa. Ntabwo "twongeyeho ibyemezo nyuma." Twubaka sisitemu mbere, hanyuma tugenzure kubirwanya.
Guhitamo Urushinge Rwicyuma Kubumba Uruganda rukora ibyuma-Reba kera Agatabo
Niba umushinga wawe utaha urimo ibyuma bya MIM bidafite ibyuma bya hydraulic manifolds, fondasiyo ya pompe, cyangwa imvange ya cobalt-idafite ibyuma, baza ibibazo bitatu mbere yo gusinya PO:
- Bashobora kukwereka itanura ryanyuma rya kalibrasi yanyuma-kandi bakerekana ko ikubiyemo ubushyuhe bwuzuye bwakoreshejwe murwego rwawe?
- Bakora ibyuma byambukiranya ibice ku bicuruzwa, ntabwo bakora R&D gusa?
- Iyo igishushanyo guhamagara “Ra ≤0.4 µm hejuru yikimenyetso,” bakora imashini * nyuma yo gucumura - cyangwa kwishingikiriza kumashanyarazi ya kabiri ikuraho urwego rukomeye?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ibisubizo yego kuri bose uko ari batatu. Ntabwo nkibisabwa byo kwamamaza - ariko nkibikorwa byanditse, bigaragara mumihanda yacu y'ubugenzuzi ISO 9001 kandi dusangiye kumugaragaro mugihe cyo gusuzuma. Ntabwo tugurisha ubushobozi. Tugurisha ibiteganijwe.
Kubisaba porogaramu aho ibyuma bitagira umwanda MIM igomba gutanga ibisobanuro byuzuye kandi byizewe, gufatanya na a guterwa ibyuma bikozwe mu ruganda itunze urunigi rwuzuye-kuva siyanse yubumenyi kugeza kugerageza imikorere-ntabwo aribyiza. Ninzira yonyine yirinda gushushanya bihenze, gutinda gutangira, no kunanirwa kumurima. Igihe kizaza ni icy'abakora inganda bafata metallurgie nk'ubuhanga-ntabwo ari outsourcing.
