Iyo umuntu ataye icyifuzo cya AMS 5387 ibice byingenzi, instinzi yanjye yambere ntabwo ari ugukurura urupapuro rwihariye. Nukwibaza niba bumva neza ibyo basaba. Iyi ngingo ikubiyemo cobalt-chromium-nikel ivanze, bakunze kwita Stellite 6 cyangwa amanota asa, yagenewe kwambara cyane na serivisi yubushyuhe bwo hejuru. Umutego rusange? Abaguzi bakunze kubihuza na satelite rusange cyangwa bakibwira ko uruganda rwose rushobora gukubitwa. Ikigaragara ni uko AMS 5387 ntabwo ari ibya chimie gusa; ni urugendo rwose kuva gushonga kugera kumurongo wanyuma wakozwe, hamwe no kuvura ubushyuhe no kugenzura ubunyangamugayo bushobora gukora cyangwa kumena igice cyagenewe, tuvuge, kashe ya moteri ya turbine cyangwa intebe ikomeye ya valve. Nabonye imishinga myinshi ihagaze kuko intumbero yari yibanze gusa kubyemezo bifatika, ntabwo ubushobozi bwibikorwa byihishe inyuma.
Ikibazo Cyibanze: Birarenze Amavuta
Gukorana na AMS 5387 ntabwo ari nko gutunganya ibyuma byoroheje. Ibirimo byinshi bya cobalt na chromium biha kwihanganira kwambara bidasanzwe, ariko uwo mutungo umwe uhindura ibikoresho byo gutema ibintu bikoreshwa. Ntushobora kujugunya kuri mashini iyo ari yo yose ya CNC. Inzira isaba gushiraho, ibikoresho bya geometrike yihariye (twishingikirije cyane kuri ceramic cyangwa CBN yinjiza kugirango irangire), hamwe nuburyo bwigiza nkana kumuvuduko no kugaburira. Ndetse inzira yo gukina irakomeye. Kugira ngo wirinde ibibazo nka micro-porosity cyangwa carbide ivangura, ubushyuhe bwo gusuka hamwe nubushyuhe mbere yubushyuhe bukenera kugenzurwa cyane. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu mugikonoshwa no gushora imari kubutaka budasanzwe, ifite ibiti by'itanura hamwe nimpapuro zerekana ko bahamagaye. Nibwo kwibuka kwinzego bifite akamaro.
Aho ibintu bishimishije ni post-casting. Ikirangantego gisaba igisubizo cyo kuvura ubushyuhe. Ntabwo arikintu cyoroshye cya annealing. Idirishya ry'ubushyuhe ni rito, kandi igipimo cyo gukonjesha - ubusanzwe umwuka wihuta cyangwa gukonjesha ikirere ku gahato - ni ngombwa kugira ngo ugere kuri microstructure yifuza. Ndibuka igice cyibigize valve mumyaka mike ishize aho umutwaro witanura wari mwinshi cyane, biganisha ku gukonja kutaringaniye. Ibice byatsinze igenzura ryibanze ariko birananirana kuburyo bugaragara mugihe cyakurikiyeho gishyushye, gihinduka muburyo bwa serivisi. Intandaro? Uburyo bwo kuvura ubushyuhe ntabwo bwafashwe nkigikorwa gikomeye.
Ibi biganisha ku ngingo ifatika yerekeye gushakisha. Ntabwo ugura gusa AMS 5387 ibice byingenzi; ufatanya nuwitanga kugenzura inzira ihagaritse. Icyitegererezo cya QSY, gihuza casting zabo hamwe no gutunganya imashini za CNC, ni inyungu ikomeye. Ikuraho urutoki-rutoki iyo habonetse inenge. Byari inenge ya casting yerekanwe no gutunganya, cyangwa guhangayikishwa no gutera imashini byateje akavuyo? Iyo itsinda rimwe rikemuye byombi, ibitekerezo byihuta birahita. Kubice byubunyangamugayo buhanitse, ibyo gukurikiranwa bifite agaciro karenze gato kuri buri gice cyigiciro cyo kuzigama kumurongo waciwe.
Imashini itomoye: Aho Theory ihura na Vise
Reka tuvuge kubyerekeye kuva muri casting igoye kugeza igice cyarangiye. Igipimo cyimashini kuri aya mavuta ni, mubyukuri, umukene. Irakora-vuba. Niba igikoresho cyawe gituye cyangwa igipimo cyawe cyo kugaburira gikabije, mubyukuri ukomanga hejuru ugerageza guca, biganisha kumeneka ryibikoresho. Ingamba ni umuvuduko mwinshi hejuru, ibiryo bihoraho, kandi ntuzigera ureka igikoresho. Gukata guhagaritswe, nko ku ntebe ya valve hamwe n’imisaraba, ni inzozi zihariye. Dukunze gukoresha inzira yo gusya trochoidal kugirango dushobore gucunga ibikoresho.
Igishushanyo mbonera ni iyindi ntwari itaririmbwe. Kuberako ibikoresho birakomeye, imbaraga zo guca ni ndende. Imiterere ihindagurika izemerera kunyeganyega, kwica ubuzima bwibikoresho no kwangiza ubuso burangiye. Twimukiye mubyuma byabigenewe, bikomye ibyuma hamwe na hydraulic clamping kubikorwa bikomeye byo gukora AMS 5387 Ibigize. Nibiguzi byamafaranga, ariko byishura muburyo buhoraho no kugabanya ibisigazwa. Ndibuka prototype ikora aho twagerageje kubika umwanya dukoresheje modular fixturing. Igisubizo cyabaye kwihanganira +/- 0.001 kuri bore tutashoboraga gufata - igice cyahindurwaga muburyo bwo gutema. Isomo ryize inzira igoye.
Kugenzura ubuziranenge hano birenze raporo ya CMM. Kubice byugarije ubushyuhe bwo hejuru, dukunze gutondeka no gukora metallographic cross-sectioning kuri sample coupons kuva kumuriro umwe. Urimo gushakisha karbide no kubura ibyiciro bisobanutse. Aha niho ibyemezo byabatanga ibicuruzwa byerekana. Amaduka agurisha ibikoresho gusa azahagarara kuriyi. Umufatanyabikorwa nka QSY, yashyizwe muri iyi niche, mubisanzwe afite isano ya laboratoire kandi akumva ko arigice cyo gutanga ibice bikora, ntabwo ari imashini yakozwe gusa.
