Iyo abajenjeri bagaragaje ibice byishoramari bidafite ingese kumashanyarazi ya hydraulic, amazu ya pompe, cyangwa peteroli ya peteroli na gazi, ntabwo bagura ibyuma gusa-bagura ituze ryikigereranyo munsi ya 300 bar, uburinganire bwa microstructure nyuma yo kuvura ubushyuhe, no kwihanganira zeru kubitwara mumihanda ikomeye. Niyo mpamvu guhitamo uburenganzira ibyuma bidafite ibyuma bishora uruganda ntabwo ari agasanduku k'isoko-ni icyemezo cyo kugabanya ingaruka.
Twabonye imishinga myinshi ihagaze iyo casting yatsinze igenzura ariko ikananirwa kugerageza igitutu kumateraniro yanyuma. Intandaro? Imiterere yintete idahuye kuva gukomera kutagenzuwe, cyangwa guhangayikishwa no guterwa no gusigara mumyubakire yimyubakire idafite uruzitiro rudakomeye mugihe cyo gutambuka hejuru. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri cyuma cyo gushora ibyuma bitagira umwanda gitangirana na AMS 5387 yujuje ibikoresho fatizo bikurikirana - ntabwo ari ibyemezo, ariko ibiti byuzuye ubushyuhe bifitanye isano na raporo zisesengura. Tugenzura ibipimo bya chromium-nikel-molybdenum mbere yo gushonga, ntabwo nyuma.
Precision Ntabwo Yongeweho Nyuma-Yubatswe Mumurongo Wibikorwa
Abatanga ibicuruzwa benshi bafata gukina no gutunganya nkintambwe zikurikiranye. Turabifata nka sisitemu imwe ikomeza yumuriro-mashini. Inzu ya pisitori ya pisitori ikozwe muri CF8M ibyuma bitagira umuyonga ntishobora gutunganyirizwa mu ruganda rwa 5-axis * nyuma yo gutara - igenewe gukuramo ibicuruzwa bike * mugihe cyubwubatsi. Itsinda ryacu ryibikoresho rikoresha uburyo bwo kwigana (ukoresheje MAGMASOFT®) kugirango hamenyekane aho bigabanuka, hanyuma uhindure amarembo no kuzamuka kuburyo geometrie yanyuma igera kuri ± 0.15 mm ya GD&T ihamagarwa - mbere yo gutema gutangira.
Uku kwishyira hamwe kuvanaho icyuho cya "cast-to-mashini" icyuho: ntagikorwa cyo gukora bitewe nuburinganire bwurukuta rutunguranye, nta redos ya CMM kumunota wanyuma kuko isura ya datum yahindutse mugihe cyo gukonja. Kubigize nkibice byumuvuduko wumuvuduko hamwe na ASME B16.34 Urwego 900, bivuze ko dufite kwihanganira imyanya nyayo ya 0,05 mm kuri 8-mm-ya diametre yo gufunga - ndetse no mubice bifite ibipimo 3: 1 hamwe nibice byambukiranya imbere.
- Igenzura ritaziguye ku gishashara cyiza: 3D-icapishijwe igishushanyo mbonera cya 25-µm hejuru yubuso, ikuraho intoki-kurangiza guhinduka
- Igikonoshwa hamwe na zircon-silica hybrid slurries-ingenzi kugirango ugere kuri Ra ≤ 1,6 µm as-cast hejuru kuri 316L yimodoka
- Muri gahunda yo kugenzura ibipimo: Buri kintu cyose kinyuramo 100% optique ya kontur yogusikana nyuma-ya-shashara na pre-firing
- Gutunganya ubushyuhe bihujwe no guta: Gukemura igisubizo kuri 1050 ° C ± 5 ° C, hagakurikiraho kuzimya amazi mu bigega bigenzurwa n'ubushyuhe (± 2 ° C)
Impamvu Cobalt Alloys Yerekana Ubushobozi bwo Gutera Ibyuma
Bamwe bashobora gutongana bati: "Ibyuma bitagira umwanda biroroshye. Kuki twibanda kuri cobalt?" Kuberako niba uruganda rushobora guhora rushyira, imashini, kandi rukarangiza T800 ya cobalt ishingiye kuri superalloy nozzles - ibikoresho bifite 45 HRC ikomeye nkibisumizi kandi byerekana hafi ya zeru ya mashini - yamenye neza ibyangombwa bisabwa ibyuma: kugenzura ubushyuhe bwumuriro, guhuza ibicuruzwa, no kutangiza ibintu.
Dukoresha protocole imwe yo kugenzura kuri 304 ibyuma bitagira umuyonga wintoki ya shaft roller nkuko tubikora kumacomeka ya AMS 5387: gupima ultrasonic kuri ASTM E114, kugenzura irangi ryinjira kuri ISO 3452-2, hamwe no kwemeza imiti byuzuye binyuze muri OES (optique yohereza ibyuka bihumanya). Nta bigufi. Nta "myitozo isanzwe". Iyo abakiriya batwoherereje ibishushanyo hamwe na ± 0.025 mm kwihanganira imyanya kuri Ø6-mm biranga mm 120 uvuye kuri datum yibanze, turasubiza hamwe na raporo yakozwe-ntabwo ari amagambo.
Gutanga kwukuri kwizerwa bitangirana nigihe-nyacyo cyo gukurikiranwa
"Gutanga ku gihe" ntacyo bivuze niba igice kigeze hamwe no kuvura ubushyuhe budafite ibyangombwa cyangwa ibikoresho bidahuye. Dushiraho buri casting idasanzwe ya QR-code ID kuri shell kubaka. Iyo kode ihuza na: raporo y'ibizamini by'ibikoresho fatizo, ibipimo by'ubushyuhe bw'itanura bivuye kuri annealing, raporo y'ubugenzuzi bwa CMM hamwe n'amakarita yatandukanijwe n'amakarita, ndetse n'imikono y'abakoresha ku marembo y'ingenzi. Abakiriya bo muri Amerika ya Ruguru hamwe n’ubumwe bw’ibihugu by’Uburayi bagera kuri aya makuru babinyujije ku rubuga rwacu rwizewe - ntabwo ari PDF zoherejwe ku byoherejwe, ahubwo ni inyandiko zerekana imibare.
Kubicuruzwa bito bito (50-500 pcs), ibikorwa byacu bitagabanije kugabanya umwanya wa 22% ugereranije nibipimo byinganda - ntabwo byihuta, ahubwo dukuraho ibizakorwa. Nigute? Twemeza gushushanya GD&T kurwanya gukina bishoboka * mbere * ibikoresho. Niba umukiriya agaragaje Rz 0.8 µm kumurongo wimbere wa mm-12 ya diametre, tuyishyiraho ibendera hakiri kare: gukora amashanyarazi, ariko gukanika imashini bizana micro-crack mu manota ya martensitike. Nibyiza guhindura ubuso burenze gusiba ibice 47 kuri QA yanyuma.
Reba Hanze ya Fondasiyo-Reba Ubufatanye Bwubuhanga
Uruganda rukora ibyuma bidafite ingese uruganda rutera ikizere ntabwo iyo ruvuze ngo "yego," ariko iyo ruvuze ngo "dore uko - kandi dore ibyo twahindura." Twafashije abadage hydraulic OEMs kongera guhindura valve manifolds kugirango bakureho impumyi zimpumyi, kugabanya ibiro bya casting 18% tutitanze igitutu giturika. Twayoboye abubaka pompe yo mu majyepfo yuburasirazuba bwa Aziya binyuze muri ASME Igice cya VIII Div. 2 kubahiriza amazu ya duplex idafite ingese ikorera kuri 120 ° C na 250 bar.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ntagurisha casting. Itanga imikorere yimikorere igenzurwa - murwego, mubyuma, no mubikorwa. Niba ubutaha bwawe bwo gushora ibyuma bitagira umwanda bigomba kurokoka umunaniro ukabije, kurwanya chloride, cyangwa kugumana ubunyangamugayo nyuma yubushyuhe bwa 10,000, tangira ukoresheje ibintu bifatika, ntabwo ari bike byateganijwe. Icyemezo ntigisezeranijwe. Byaragaragaye-ubufindo bumwe, raporo yubugenzuzi, ikizamini cyumuvuduko icyarimwe.
