Iyo abajenjeri bagaragaje ibice byo gutunganya cobalt ya pompe ya pompe hydraulic, valves yo hepfo, cyangwa shitingi ya winch yambaye cyane, ntabwo bahitamo gusa ibikoresho-bahitamo gushikama kurwego rwa 300 MPa, kwihanganira gutera kuri 650 ° C, hamwe na microstructural guhuza ibice 500. Niyo mpamvu gushakisha kwizerwa cobalt alloy imashini itunganya uruganda gake birangirana nibiciro byatanzwe. Itangirana na metallurgical accountability, kugenzura inzira-axis nyinshi, no kwihanganira zeru gutandukanya karbide muri AMS 5387 cyangwa T800 yo mu rwego rwo hejuru.
Kuki cobalt alloys isaba ibirenze ubushobozi busanzwe bwa CNC
Cobalt ishingiye kuri superalloys nka Stellite 6B, Haynes 188, hamwe na T800 yihariye irwanya kwambara no kwangirika - ariko kandi basya ibikoresho 3-5 × byihuse kuruta ibyuma bitagira umwanda. Twabonye amaduka asubiramo amaboko ya cobalt nozzle gusa kugirango akureho 40% yibice byambere byambere kubera kuganira kwatewe no kuganira hejuru yubuso bwimbere. Intandaro? Ibikoresho bikomeye byirengagije kwaguka k'ubushyuhe budahuye hagati ya cobalt (10.4 µm / m · K) na plaque ya aluminium. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri murimo wa cobalt utangirana n'ikarita yindishyi zumuriro-bigenzurwa na progaramu ya infragre ya scan mugihe cyo gutambuka. Nuburyo dufata ± 0.008 mm kuzenguruka kuri 120-mm-diametre ya cobalt alloy plug mugihe dukomeza Ra ≤0.4 µm hejuru yikimenyetso.
Ubushobozi bune budasubirwaho bwukuri bwa cobalt alloy gutunganya ibice byuruganda
Ikigo gisaba ubuhanga bwa cobalt kigomba gutanga ibirenze kugabanya umuvuduko. Ukurikije imyaka 12 yumusaruro wibikoresho bya pompe, ubwo bushobozi bune butandukanya abafatanyabikorwa bagaragaye nabacuruzi bizeye:
- Gukurikirana ibikoresho kugeza kumubare wubushyuhe- ntabwo ari urusyo gusa. Imikorere ya Cobalt ishingiye kubintu bya karubone na tungsten; gutandukana kwa 0,02% muri karubone muri AMS 5387 ihindura ubukana kuva kuri 42 HRC ikagera kuri 49 HRC, bikagira ibyago byo kuvunika gukabije mu gupakira ibintu.
- Kwishyira hamwe-guterimbere-gukora-akazi—Nta ntoki hagati yububiko nububiko bwimashini. Inzu yishoramari-cobalt inzu igabanuka bitateganijwe keretse niba ibikoresho byo gutunganya ibyerekanwe nkibikoresho bya datum. Twebwe imashini ya silinderi mu masaha 72 uhereye kunyeganyega, dukoresheje CMM imwe yagenzuye casting geometrie.
- Guhuza ubushyuhe bwo guhuza- gukemura annealing bigomba kubanziriza gutunganya bwa nyuma kugirango ugabanye imihangayiko isigaye. Ariko kurenza urugero bigabanya karbide ya chromium, bikabangamira kurwanya ruswa. Ibiti by'itanura byacu byambukiranya nimero ya buri gice kandi bigahuzwa na raporo ya CMM nyuma yubushyuhe.
- GD&T kwemeza mbere yo gukata- cyane cyane kwihanganira umwirondoro kuri cobalt nozzles. Umwirondoro wa mm 0,05 kumuhamagaro wintebe ntushobora kugerwaho nurusyo rusanzwe. Twigana inzira yo gutandukana muri VERICUT, hanyuma twemeze hamwe na optique ya optique ya scaneri - ntabwo ari CMM gusa.
Aho abatanga isoko basanzwe bananiwe-nuburyo uruganda rwibanze rusubiza
Bamwe mubakora bafata cobalt nkicyuma gikomeye: ibiryo bimwe, ubukonje bumwe, inshuro imwe yo kugenzura. Ibyo birananirana kuko ubushyuhe buke bwa cobalt butwara ubushyuhe kumpera. Twitegereje umukiriya umwe wa cobalt alloy ibice 6 bya pompe byananiwe gupimisha umunyu nyuma yamasaha 200-bitatewe nubusembwa bwibintu, ahubwo byaturutse kuri micro-crack zatewe numuvuduko ukabije w’umwuzure ukabije (urenga akabari 12 kumyitozo yimbere ya mm-3). Igisubizo cyacu? Amavuta ntarengwa yo kwisiga (MQL) hamwe namavuta ashingiye kuri ester, yatanzwe kuri psi 80 binyuze muri spincle nozzles, bigahuzwa na spindle RPM. Ubusugire bwubuso bwateye imbere 70%, nubuzima bwibikoresho byikubye kabiri.
Ikindi cyuho gisanzwe: kwipimisha kumikorere. Amacomeka ya cobalt ntabwo "yakozwe" mugihe ibipimo byanyuze. Igomba gufunga akabari 414 mugihe izunguruka 120 rpm irwanya intebe zikomeye 420. Turagerageza buri kintu cyose kubikoresho byubatswe na hydraulic bigana kwigana serivisi nyayo, ubushyuhe, hamwe ningaruka zumuvuduko - amakuru yinjiye kandi asangira nabakiriya.
Guhitamo cobalt alloy imashini itunganya uruganda: urutonde rwibikorwa
Mbere yo kohereza ibishushanyo, baza ibibazo bitanu - kandi usabe ibisubizo byanditse:
- Urashobora gutanga ubushyuhe-bwo kuvura ibyiciro bitatu bya nyuma AMS 5387 yoherejwe?
- Nubuhe burebure bwawe budashyigikiwe na 8-mm-diameter ya cobalt imbere yimbere - kandi ni ubuhe buryo bwo gukoresha ibikoresho bubigeraho?
- Ukora ibizamini bya ultrasonic nyuma yo gutunganya ibice bikomeye bifite uburebure bwa mm 25?
- Nigute ushobora kugenzura ubusugire bwubuso ku ntebe ya cobalt yakozwe? .
- Urashobora gufata umwanya wukuri wa ± 0,015 mm kuri diametero eshatu za coaxial muburyo bumwe bwa mm-180 z'uburebure bwa cobalt center shaft roller?
Niba igisubizo icyo ari cyo cyose kidasobanutse, cyatinze, cyangwa ibyerekeranye "inzira zisanzwe," komeza urebe. Cobalt ntabwo ibabarira ibitekerezo.
Icyitonderwa cya nyuma: ibisobanuro ntabwo ari ishami-ni urukurikirane
Ibice bikomeye bya cobalt biva muburyo bukomeye hagati yubumenyi bwibintu, gutunganya imashini, no kwemeza imikorere. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD, Urwo rutonde - ibikoresho → inzira → gupima → imikorere - niyo mpamvu abajenjeri bagaruka kubikoresho bya cobalt alloy imashini ikora uruganda rwumwaka. Precision ntabwo ipimwa muri micron yonyine. Bipimirwa mu cyizere.
