Guhitamo uburenganzira icyuma inzira ntabwo ari ugutora izina kurutonde. Nibijyanye na physics, geometrie, nibikorwa-mbere yuko isuka ya mbere isukwa. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twashyizeho ibice birenga 12,000 byihariye bya valraulic hydraulic, amazu ya pompe, hamwe na shitingi ya winch yo hanze. Kunanirwa kwose byatwigishije ikintu gifatika: guta umucanga ntibizaba bifite mm 0,05 mm ku ntebe ya cobalt-alloy nozzle; gushora imari gusiba niba usibye ubushyuhe kuri AMS 5387; na centrifugal casting birananirana mugihe umubyimba wurukuta wagabanutse munsi ya mm 18 kumurongo wa silinderi mwinshi.
Tangira igice - ntabwo ari inzira
Ba injeniyeri benshi batangira kubaza ngo "Ni ubuhe buryo bwo gukora ibyuma bwiza?" Icyo kibazo kiganisha ku buryo budasobanutse cyangwa kudakora neza. Ahubwo, baza ibintu bitatu: Ni izihe mitwaro izatwara? Ni hehe binanirana muri serivisi? Ni ubuhe buryo bwo kwihanganira bugomba kurokoka imashini yanyuma?
Twigeze kwakira igishushanyo cya T800 cobalt alloy piston pompe inzu-igenewe gukora 350 bar. Umukiriya yerekanye umusenyi. Ariko nyuma yo kwerekana ubushyuhe bwumuriro hamwe na microstructure isubiramo, twasabye gushora imari hamwe no gukomera. Kubera iki? Gutera umucanga byabyaye imiterere idahuye hafi yicyambu cya valve. Ibice bibiri byipimisha byacitse kuri 280 mugihe cyo guturika. Gutera ishoramari byatanze intera imwe ya dendrite, yatsindiye kwemeza 420, kandi igabanya ibicuruzwa nyuma yimashini biva kuri 37% bikagera kuri 9%.
Kwikuramo: Geometrie itwara inzira yo guhitamo. Uruzitiro ruto, rugoye hamwe na GD&T ihamagarira gushora imari. Ibice biremereye byubatswe? Gutera umucanga bitanga ikiguzi cyiza hamwe nubushyuhe bwumuriro. Guhinduranya hamwe n'ubugari bumwe? Centrifugal casting itanga ubucucike nubuzima bwumunaniro - cyane cyane kubishingwe bya pompe idafite ibyuma byangiza isuri yamazi yumunyu.
Ibikoresho bisobanura igisenge cyawe - n'imbibi zawe
Ntushobora guta ibyo udashobora kugaburira. Amavuta ya Cobalt-nikel nka AMS 5387 na T800 afite aho ashonga cyane (1370–1420 ° C), amazi make, hamwe no kumva cyane ubushyuhe bwikigereranyo. Twabonye amaduka agerageza kubahatira mubibabi byumucanga-gusa kugirango tubone gukonja, kugabanya ubukana, no gucamo interdendritic. Ibi ntabwo ari "kunanirwa inzira." Nibintu bidahuye nibikoresho.
Ikigo cyacu gikora imirongo ibiri ibangikanye: imwe yatunganijwe neza mubyuma na karubone (guta umucanga, kugeza kuri kg 500), ikindi cyeguriwe super-alloy superalloys (gushora imari, gusuka bifashwa na vacuum, ibishishwa bya ceramic bishyushye). Kuri AMS 5387 nozzles, dukoresha sisitemu y'ibishishwa ishingiye kuri silika yashyutswe kugeza kuri 1050 ° C - ntabwo ari 800 ° C - kugirango twirinde guhungabana kandi tumenye neza ko byuzuye. Ihinduka rimwe ryibice byagabanije okiside yimbere imbere ya 63% mugenzura ryamezi 18 ashize.
Ntukibwire ko "ibyuma bidafite ingese" bisobanura ikintu kimwe. 316 idafite umwanda yitwara bitandukanye cyane na 17-4PH cyangwa F22. Kandi cobalt alloys isaba ingamba zitandukanye, kuzamuka, no gukonjesha kuruta Inconels ishingiye kuri nikel. Niba uwaguhaye isoko atagusabye urupapuro rwuzuye rwa metallurgical-harimo amateka yo kuvura ubushyuhe hamwe nibisabwa bya tensile / ingaruka-usanzwe inyuma.
Kwishyira hamwe bikubita mu bwigunge - igihe cyose
Gutera neza ntacyo bimaze niba bidashobora gukorerwa imashini yo gucapa. Turabibona buri munsi: umukiriya atumiza umusingi wicyuma gishyirwaho umucanga, hanyuma ugasaba ± 0,025 mm uburinganire bwa mm 600 × 400. Ntibishoboka nta kugabanya imihangayiko no guhuza neza. Cyangwa ishoramari ryashizwemo cobalt igera hamwe na 0,3 mm flash kumurongo wo gutandukana - hanyuma ikangwa kubera ko iduka rya CNC ridafite ibikoresho birambirana bito bya mm 3.2.
Niyo mpamvu TECHNOLOGIQUE QINGDAO QIANGSENYUAN ihuza casting, gutunganya ubushyuhe, gutunganya imashini nyinshi, no kugenzura CMM munsi yinzu imwe yujuje ISO. Iyo tuvuze umubiri wumuvuduko wumuvuduko, twigana ibikorwa byose byakazi: guta indishyi zo kugabanuka, igihe cyo kugabanuka kwingutu, igishushanyo mbonera cyo gufunga urukuta ruto, hamwe no gupima optique yubuso bukomeye. Ntabwo dutanga ibice-dutanga ibice byagenzuwe neza.
Uku kwishyira hamwe kugabanya igihe cyo kuyobora 31% kubicuruzwa bito bito kandi bikuraho 94% byimikorere. Icy'ingenzi cyane, itwemerera gukemura ibibazo mbere yuko bibaho - nko guhindura amarembo kugirango ugabanye imihangayiko isigaye muri winch center shaft roller kugirango gusya kwa nyuma bigere kuri Ra 0.4 µm nta kuganira.
Baza ibibazo bikwiye - mbere yo kwiyemeza
Mbere yo guhitamo a icyuma umufatanyabikorwa, genzura izi ngingo eshanu:
- Ese bemeza uburyo bwabo bwo gukina - ntibagenzura ibisubizo gusa? Baza ibyemezo byo kwigana raporo hamwe nubushyuhe bwa gradient ibiti kuri buri kintu.
- Bashobora gukurikirana buri cyiciro kubikoresho fatizo-harimo raporo y'ibizamini by'urusyo hamwe nisesengura rya spekitografiya? Ntakidasanzwe kuri cobalt cyangwa nikel.
- Bakora muri gahunda ya CMM igenzura ku cyatsi cyangwa ibishashara - ntabwo ari ibice byanyuma? Nibyingenzi kuri GD & T-iteraniro riremereye nkamazu ya pompe ya silinderi.
- Ni ikihe gipimo cyagaragaye cyerekana umusaruro kuri alloy na geometrie yawe? Ntabwo ari “impuzandengo y'inganda” - yawe.
- Boba bafatanya gusubiramo ibyakozwe mugihe cyo gusohora injeniyeri - atari nyuma yo gutangira ibikoresho? Dutondekanya ibyago nkibicuruzwa bifata ceramic shell ibikoresho cyangwa radii ntoya cyane kuri pin.
Nta buryo bwa "bwiza" bwogukoresha ibyuma. Hariho gusa ibikwiye-kubibazo byumutwaro wawe, ibikoresho byawe, kwihanganira ibintu, hamwe nidirishya ryukuri ryo kugemura. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri gukina nka sisitemu - ntabwo ari ibice. Kuberako muri sisitemu ya hydraulic, ibikoresho bya peteroli na gaze, hamwe na moteri yimodoka, cluster imwe ya porosity ntabwo ari inenge yo kwisiga. Ninzira yamenetse. Inkomoko y'umunaniro. Kunanirwa kumurima gutegereza kubaho.
Hitamo inzira yubaha intego zigice cyawe-ntabwo ari imiterere yacyo gusa.
