Iyo abajenjeri bagaragaje ibice bya pompe hydraulic, valve yamavuta ya peteroli, cyangwa sisitemu ya winch iremereye cyane, "kwihanganira cyane" ntabwo ari ijambo ryo kwamamaza-nibisabwa bidashoboka. Gutandukana kwa mm 0,01 muri cobalt alloy nozzle intebe irashobora gutera isuri imburagihe. Guhuza mm 0,025 mumazu ya piston pompe ya pisitori bishobora gutera igihombo gikomeye. Niyo mpamvu abatanga OEM kwisi yose hamwe nabatanga Tier-1 badashakisha gusa a cnc gutunganya ibice byuruganda. Bashakisha imwe ifata ituze rinini, guhuza metallurgjique, no kwemeza imikorere nka disipuline idatandukanye.
Kwihanganirana kwisi bisaba kwerekana icyuho cyibikorwa-byihuse
Twabibonye inshuro nyinshi: umukiriya atanga igishushanyo cya GD & T gikungahaye kuri AMS 5387 cobalt alloy plug, ategereje ± 0.005 mm kuri bores zikomeye n'umwanya nyawo muri mm 0.01. Porotipire yambere yatsinze igenzura-ariko ikananirwa kugerageza imigendekere ya 3000 psi. Kubera iki? Kuberako utanga isoko yatunganije igice * cyo gucapa *, ntabwo * gukora *. Basibye amateka yubushyuhe nyuma yo kuvura ubushyuhe. Bakoresheje karbide isanzwe yinjizwamo ibikoresho bya T800 bishingiye kuri cobalt-bitera micro-chiping kuri radiyo. Twarayifashe mugihe cyo gukora CMM scan mugikorwa cya kabiri. Nibwo isuzuma ryubwubatsi ryahinduwe riva kuri "Urashobora kubikora?" kuri “Twemeza dute ko ikora?”
Inzego enye zo kugenzura - ntabwo ari serivisi enye gusa
Ubushobozi bwo kwihanganira cyane ntabwo bushyizwe hejuru yimashini rusange. Yubatswe mubikorwa-kuva ibyemezo byibanze kugeza ikizamini cyanyuma. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibi bivuze:
- Ibikoresho byakurikiranwe: Buri fagitire ya AMS 5387 igera hamwe na raporo yikizamini cyuzuye. Twambukiranya chimie kurwanya ASTM A494 hanyuma tumenye imiterere yintete dukoresheje metallografiya mbere yuko imashini itangira.
- Imashini ihindagurika kugirango imyitwarire ibangikanye: Kubice bya T800 cobalt-nikel, dukoresha ibikoresho bya PCD bivura hamwe nibiciro byigaburo byahinduwe kuri buri cyiciro gikomeye - ntabwo ari gahunda rusange ya CNC. Ubusugire bwubuso bugenzurwa na cyera-urumuri interferometrie, ntabwo Ra yasomye gusa.
- Gutera-gutunganya amaboko yakozwe, ntabwo byafashwe. Kubera iki? Kuberako guhangayika gusigaye muri pompe ya pompe bizaterwa imbaraga zifatika, guta guhuza bore. Dupima kugoreka mbere na nyuma yo guhangayika dukoresheje optique ya optique ya 3D.
- Iyemezwa ryanyuma rifitanye isano na fiziki ikoreshwa: Amazu ya valve yimyubakire ntabwo abona raporo ya CMM gusa. Irabona ibizamini bya hydrostatike kuri 1.5 × umuvuduko ukabije, ikurikirwa no kugenzura irangi-ryinjira hejuru yikimenyetso. Nta na kimwe kidasanzwe.
Kuki "imigenzo" idakwiye gusobanura "kumvikana"
Amaduka amwe afata ibice byabigenewe nkibisohoka - byashyizwe mumashini isanzwe hamwe na programmes bato. Urwo rugero rusenyuka vuba mugihe igice cyawe ari urwego rudasanzwe rusanzwe rwa shitingi ya sisitemu yo gutwara ibinyabiziga: gukomera kuri HRC 58-62, hamwe no guhagarikwa guhagarikwa hejuru ya 12 ikomye, hamwe no kurangiza hejuru ya .4 0.4 μm Ra kubinyamakuru bitwara imitwaro.
Duha imirimo nk'iyi ingirabuzimafatizo zabugenewe - zikoreshwa n'abakozi bahuguwe kuri protocole ya cobalt alloy, dushyigikiwe nabatekinisiye ba metrology bemejwe na ISO 17025, kandi dushyigikiwe nitsinda ryabashushanyaga kuvuga neza muri ASME Y14.5 na ISO 1101. Igihe pompe yo muri Amerika ya ruguru OEM yadusabye guhindura amazu yabo ya pisitori ya pisitori kugira ngo hashyizwe ahagaragara imashini nyinshi. Twagumanye imiyoboro yo gukonjesha imbere (ntibishoboka ko imashini ikora post-cast) mugihe twongeyeho kwihanganira-kwihanganira ibintu byo hanze byifashishije urusyo rwa 5-axis. Igihe cyo kuyobora cyagabanutseho 22%. Ibiro byagumye bisa. Imikorere yiyongereyeho 17% mu bizamini byo gusiganwa ku magare.
Niki "umufatanyabikorwa wizewe" atanga mubyukuri-birenze amagambo
Umufatanyabikorwa wizewe yerekana ibikorerwa ingaruka * mbere yo * gukata ibyuma - atari nyuma yo gusubiramo. Turasubiza ibishushanyo bisobanuwe hamwe na GD&T ibisobanuro byerekana: "Iyi myanya nyayo yo guhamagarwa ivuguruzanya no gutoranya inguni - itanga igitekerezo cyo kwimura datum B ku buso bwakozwe." Cyangwa: "Ibikoresho bya T800 muri iki gice cyoroheje bizakenera inkunga mugihe cyo kurangiza; saba kongeramo imbavu zigihe gito (kuvanaho nyuma yubushyuhe)."
Ibi ntabwo ari inama ngishwanama. Ni ukwirinda ibiciro. Umukiriya umwe w’i Burayi yirinze amadolari 84.000 y’amadorari yemera icyifuzo cyacu cyo kuva mu guta umucanga ukajya mu ishoramari ry’umubiri wabo wa cobalt alloy nozzle - hashingiwe ku makuru atandukanye y’urukuta kuva ku gice cyabo cyambere. Ikindi cyakijije ibyumweru 3 mugukurikiza icyifuzo cyacu cyo kuvura ubushyuhe, cyakuyeho intambwe ya kabiri igororotse.
Iyo minzani. Waba ukeneye prototypes 3 kugirango yemeze cyangwa ibice 1200 / umwaka byumuvuduko wumuvuduko, protocole yubugenzuzi igumaho. Gukurikirana ibintu bigumaho. Injeniyeri usubiramo igishushanyo cyawe yakoze kuri AMS 5387 ibice 11 - ntabwo ari amezi 11.
Urebye imbere: aho ibisobanuro bihuye nibiteganijwe
Imipaka ikurikira ntabwo yihanganirana wenyine. Ni uguhuza gukomeye hagati yubumenyi bwibintu, gutunganya fiziki, no kwemeza imikorere. Turimo kwagura R&D kubikorwa bya Hybrid casting-mashini ikora kumateraniro igoye ya pompe-kandi twubaka ubushobozi bwimbere kugirango twemeze ubuzima bwumunaniro kuburwayi bwa serivisi nyayo ituruka kubafatanyabikorwa.
Niba porogaramu yawe isaba sub-0.01 mm gusubiramo kuri superalloys, microstructure ihoraho mubice 500, cyangwa gutanga zeru-inenge kubutumwa bukomeye-hydraulic-ukeneye ibirenze a cnc gutunganya ibice byuruganda. Ukeneye umufatanyabikorwa ufite ibisobanuro bya "precision" bitangirira aho igishushanyo kirangirira.
