Iyo abajenjeri bagaragaje ibice bya pompe hydraulic, valve yo hanze, cyangwa sisitemu ya winch iremereye, ntibakenera "gufunga bihagije." Bakeneye uruganda rukora neza ibisohoka aho ± 0.01 mm kwihanganira ntabwo ari bonus-ni shingiro. Twabonye abakiriya basubiza ibyiciro bitatu bya prototypes kuko gutembera kwinshi muri cobalt alloy nozzles byateje isuri imburagihe. Twarebye igihe cyo gutanga cyasenyutse mugihe casting shrinkage itishyuwe muburyo bwa CNC. Niyo mpamvu twibanda kubikorwa bikora-ntabwo ari udutabo, ahubwo ni ukuri-kwisubiramo kwisi munsi yigitutu, ubushyuhe, nuburemere bwa cycle.
Ukuri-Isi Yuzuye Itangirana no Kugenzura Ibikoresho-Ntabwo ari Imashini gusa
Amaduka menshi afata ibikoresho nkintangiriro. Turabifata nkintambwe yambere yintambwe. Amavuta ya Cobalt-nikel nka AMS 5387 na T800 ntabwo bigoye gukora imashini gusa-birakomeye mubyuma. Gutandukana kwa 5 ° C mugihe cyo gukemura anne ihindura ingano ya karbide ikwirakwizwa. Izo mpinduka zambara zirwanya amazu ya pompe ya silinderi kugeza kuri 37%, ukurikije ibizamini byimbere byimbere-12,000. Dufatanije rero na fagitire zemewe hamwe nabatanga ibicuruzwa bitanga ubushyuhe bwuzuye - kugeza kumurongo wamashyiga hamwe nibipimo byo gukonjesha - ntabwo ari ibyemezo byurusyo gusa. Mugihe umukiriya yatwoherereje igishushanyo cya plaque idasanzwe ya cobalt alloy plug, twashyize ahagaragara urutonde rwubukomezi bugereranije nimbaraga zifatika zingana kuri ubwo bushyuhe. Igisubizo? Inzira ivuguruye yo kuvura itanga HRC 42-44 * na * yagumanye ubukana bwingaruka hejuru ya 28 J kuri –20 ° C. Nta rework. Nta gutinda.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Nuburyo Ufata Tolerance Mubikorwa byose
Gutera + gutunganya + kurangiza munsi yinzu imwe bihindura byose. Reka dusuzume ibinyabiziga bya winch center shaft roller: umusenyi ushyizwe mubyuma byangiza (ASTM A536 Grade), hanyuma ukarangiza-ukagera kuri mm 0.008 mm hejuru yikinyamakuru, hanyuma ukinjira-gukomera kuri 58-62 HRC. Niba izo ntambwe zibaye mubacuruzi batatu, kugoreka ubushyuhe bwo guterwa no guhagarika umutima bifungwa mbere yuko imashini itangira - hanyuma ukirukana geometrie aho kuyifata. Ku kigo cyacu cya Qingdao, dukora imashini mu masaha 48 nyuma yo guta shakeout. Dukoresha muri CMM igenzura nyuma yo gukomera, kurangiza, no kurangiza - buriwese uhujwe na GD&T guhamagarwa, ntabwo ari ibipimo byizina gusa. Kububiko bwa pisitori ya piston pompe, turagenzura bore silindricity * mbere * ya nyuma yubusa, ntabwo nyuma. Ibyo bifata ibintu biterwa no kugoreka hakiri kare. Umwaka ushize, ibi byafashe mm 0,015 mm ya taper muri 17% yibice byambere-birinda ibiro 220 by'ibisigazwa hamwe n'ibyumweru bitandatu byongeye kugaragara.
Ubwiza ntibugenzurwa-Bwubatswe, Intambwe ku yindi
Ntabwo dukora "ubugenzuzi bwa nyuma." Dukora igenzura-ryerekanwe. Ibikoresho fatizo byinjira bibona isesengura ryerekana * na * ultrasonic igerageza kubutaka bwisi - cyane cyane kubice bya pompe AMS 5387 ihura nibisukari byumuvuduko ukabije. Mugihe cya CNC, abakoresha bambara ibikoresho bambara kuri passe bakoresheje indangagaciro zapimwe na laser-ntabwo ari igihe cyagereranijwe. Nyuma yo kuvura ubushyuhe, buri kintu cyose gikora ikarita ya microhardness ikoresheje ibice bitatu. Ibice byanyuma bibona ibizamini bikora: umuvuduko wumuvuduko urageragezwa kuri 1.5 × umuvuduko ukabije; cobalt alloy nozzles ikorerwa isuri hamwe na 80-micron alumina slurry kuri 30 m / s umuvuduko. Kandi yego - tubika amakuru yose. Ntabwo ari raporo gusa. Amadosiye ya CMM yuzuye, amashusho yerekana amashusho yumuriro, icapiro rikomeye. Gukurikirana ntabwo bijyanye no kubahiriza. Nukumenya * neza * impamvu igice # W-8823 gifashe 0.005 mm kuzenguruka mugihe # W-8824 yatwaye mm 0,012 - no kugikosora mbere yubushyuhe butaha.
Icyo Ibi bivuze kumushinga wawe utaha
Niba gusaba kwawe bisaba kwihanganira byimazeyo kuri superalloys, ibintu bigoye, cyangwa ibikorwa-bikomeye-ntutangire kubisabwa. Tangira usubiramo ibyakozwe. Ohereza pake yawe ya GD&T. Tuzashyira ibendera aho inguni zinguni zivuguruzanya na casting bishoboka, aho inkuta zoroheje zishobora kugoreka mugutunganya ubushyuhe, cyangwa aho ubuso burangirira hejuru burenze ibyagerwaho nta gusya kwa kabiri. Twafashije abakiriya ba peteroli yo muri Amerika ya ruguru kugabanya igihe cyo kuyobora 30% muguhindura ishoramari-gusa-bishushanya ibishushanyo mbonera-bigumana imbaraga mugihe cyo gukuraho ibikorwa bitanu byisumbuye. Kuri hydraulics yu Burayi OEMs, twujuje ibyangombwa bya T800 bivangwa na EN 10204 3.2 ibyemezo-tutiriwe twongera ikiguzi cyangwa ingengabihe. Ibice bya mashini yibikoresho byububiko ntibipimirwa mububiko bwa spindle cyangwa hasi. Bipimirwa muburyo bwinshi uhindura-nuburyo butunguranye butera guterana. Ngiyo igipimo dufite. Igihe cyose.
