Iyo ba injeniyeri bagaragaje 2Cr13 ibyuma bitagira umwanda kumibiri ya hydraulic ya valve, inzu ya pompe ya piston, cyangwa imashini ya shitingi ya winch, ntabwo bahitamo gusa ibikoresho-bahitamo gushikama kumurongo munsi ya 300+ yumuvuduko wumubari, kurwanya kwangirika mumashusho anyerera, hamwe nubukomezi buhoraho nyuma yo kuvura ubushyuhe. Niyo mpamvu gushakira ukuri 2Cr13 uruganda rukora ibyuma-Ntabwo ari umukozi wubucuruzi cyangwa uruganda rusange-rugamije-ntirushobora kuganirwaho. Twabonye imishinga myinshi itinda nimbaraga zidahuye (Rm), HRC 28-32 idahuye nyuma yubushyuhe, cyangwa microcrake zo hejuru zagaragaye gusa mugihe cyo gukora ibizamini.
Impamvu 2Cr13 isaba ibirenze gutunganya ibyuma bitagira umuyonga
2Cr13 ntabwo ari austenitis nka 304-ni martensitike. Ibyo bivuze ko imikorere yacyo ishingiye rwose ku mateka yubushyuhe nyayo: guhindagurika kuri 980-1050 ° C, kuzimya amavuta, hanyuma gushyuha hagati ya 600-750 ° C kugirango ikubite intego idatanze ubukana. Isoko rusange rishobora gutanga "2Cr13" yujuje imiti ya GB / T 1220 - ariko ikananirwa kumashini. Twapimye ibyiciro aho imbaraga zitanga umusaruro zitandukanye ± 45 MPa kuri tombora kubera igipimo cyo gukonjesha kitagenzuwe cyangwa igihe cyo gutwarwa kidahagije. Ingaruka nyazo kwisi? Inzu ya silinderi yacitse mugihe cyamagare yumuvuduko kuri bar 220 - ntabwo ari kuri weld, ahubwo ni mukarere fatizo yibasiwe nubushyuhe.
Aha niho guhuza kwishyira hamwe bifite akamaro. Mu kigo cyacu cya Qingdao, turagenzura urunigi rwuzuye: impapuro zemewe zitangwa (hamwe na raporo y'ibizamini by'urusyo rushobora kugera ku mubare w'itanura), CNC ikora imashini igenzura ubukana, ifuru ifashwa na vacuum ifasha hamwe na ± 3 ° C, hamwe n'ubugenzuzi bwa nyuma bwa CMM kurwanya abahamagarwa ba GD&T - ntabwo ari ibipimo by'izina gusa. Nta ntoki. Nta cyiciro-cyo-gukekeranya.
Ubushobozi bune butandukanya 2Cr13 Uruganda rukora ibyuma nibindi
- Indero ya Metallurgical: Twemeza ubushyuhe bwa 2Cr13 dukoresheje spark spectrometry mbere yo gutunganya-hanyuma tukagerageza nyuma yubushyuhe kugirango twemeze kugumana karubone no kugereranya kwa Cr / Mn. AMS 5387 cobalt alloy ibice bisangiye laboratoire imwe, bityo rero guhuza ibintu ntabwo ari theoretical.
- Imashini-yubushyuhe bwo kuvura: Utugingo twinshi twa CNC selile zifatanije hamwe nitanura ryaka. Ibice bigenda neza uhereye kurangiza bikarangwa n'ubushyuhe - nta gukonjesha ibidukikije gukurura impagarara zisigaye. Igisubizo: inzu ya pompe ya piston ifata ≤0.015 mm kwihanganira kuzenguruka kuri mm 180, nubwo nyuma yamasaha 500 yo gutera umunyu.
- Kurangiza imikorere. Kuri shitingi ya winch, dukoresha gusya neza hamwe no kugenzura igihe nyacyo cyo kugenzura (Ra ≤0.4 μ m) kugirango twirinde kwambara igihe kitaragera.
- Traceability yatetse, ntabwo ihindagurika: Buri kintu cya 2Cr13 cyoherejwe hamwe nicyemezo cya digitale cyerekana ibintu fatizo, ibikoresho byo kuvura ubushyuhe, raporo ya CMM ifotora, hamwe nindangamuntu. Ntabwo ari "kubahiriza" gusa - birashoboka.
Igiciro cyo Guhitamo Ikibi-Kandi Mubyukuri Bisaba Kubona neza
Abaguzi bamwe birukana igiciro gito. Noneho bakuramo ibiciro bitatu byihishe: kongera gukora (twabonye igipimo cya 22% cyakuweho kubice 2Cr13 bivuye kumaduka atabigenewe kubera decarburisation), kunanirwa kumurima (guteranya icyuma kimwe cyafashwe mubikoresho bya peteroli yo mumazi birashobora kugura amadolari 17k / isaha yo kumanura), no gutinda kubishushanyo mbonera (GD&T yo kwemeza ifata amasaha 72 hano - ntabwo ari ibyumweru 3).
Igiciro cyacu cyerekana icyo bisaba gukora 2Cr13 iburyo: ibyemezo byongeweho byemewe (bitavugwaho rumwe), ibikoresho byabigenewe byo gutunganya cyane (gushyiramo karbide hamwe na PVD TiAlN), hamwe no kugenzura ibice 100% bya magnetiki ku bice bikomeye. Ariko abakiriya bahora batubwira ROI ikubita kuri prototype-mugihe ibice byabo 5 byambere batsinze ikizamini cyakazi kuri gahunda, ntagerageza rya kabiri rikenewe.
Kureba imbere: Aho Precision 2Cr13 Gukora bigiye
Ibikurikira-gen bisaba guhuza gukomeye hagati yubukorikori hamwe na geometrie ikozwe. Ubu turi kuzuza ibisabwa bivangavanze: gushora imari 2Cr13 hamwe no kwihanganira inshundura-net (± 0.3 mm), hagakurikiraho umurongo wa axe eshanu kugirango ugere ku mubyimba wurukuta kugeza kuri mm 4.2-utabangamiye ubuzima bwumunaniro kuri 10⁷ cycle. Icyarimwe, itsinda ryacu R&D ryemeza ASTM A957 yubahiriza prototyping yihuse ya 2Cr13, igabanya igihe cyo kuyobora kuva ibyumweru 12 kugeza kumunsi 18 kuri geometrike yujuje ibyangombwa.
Niba gusaba kwawe bisaba ibyuma 2Cr13 bidafite ingese ikora - ntibitambutsa impapuro gusa - ukeneye umufatanyabikorwa ufata metallurgie nkubuhanga, ntabwo ari amasoko. Ibyo bitangirana no kubaza ibibazo bikwiye: Urashobora kunyereka umurongo wo kugabanura ubushyuhe bwukwezi gushize? Raporo yawe ya CMM ikubiyemo amakuru yindishyi ziterwa na drift? Ibikoresho byawe birashobora guhuzwa nibiti by'itanura - cyangwa numero imwe gusa?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ibisubizo muri buri gice. Kuberako muri sisitemu ikora cyane, ntakintu nka "cyiza gihagije" ibyuma bitagira umwanda.
