Xa indlu yakho yevalve yehydraulic kufuneka ibambe ± 0.02 mm ukunyamezela phantsi kwe-350 bar pulsation-okanye i-cobalt alloy pump nozzle yakho iphila kwiiyure ezingama-8,000 kwinkonzo yegesi emuncu-awuyikuyalela nje ukuphosa. Uyafaneleka ukuba a umzi-mveliso we-Foundry ochanekileyo njengolwandiso lobuchwephesha beqela lakho lobunjineli.
Sibone iiprojekthi ezininzi kakhulu zimile kwisango le-Foundry: i-dimensional drift emva konyango lobushushu, i-micro-shrinkage kumacandelo amancinci e-AMS 5387, ii-callouts ze-GD&T zitolikwa ngokungafanelekanga "njengoluhlu olwamkelekileyo" endaweni yemida enzima. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke into etyhidiweyo njengenxalenye esebenzayo-kungekhona i-blank ukuba ifakwe kamva. Oko kuthetha ukulawula i-metallurgy * phambi kokuba * ukugalela, ukuqinisekiswa kwesakhiwo senkozo * emva * kokuqina, kunye nokutshixa ijometri * ngexesha * lokugqiba i-CNC-konke phantsi kophahla olulodwa lwe-ISO-certified eQingdao.
Kutheni ukunyamezela ukuphosa kuqala ngaphambi kokuba isikhunta sivale
Uninzi lweentsilelo zokuphosa ezichanekileyo zibuyela emva kwizikhewu ezithathu ezinokuphepheka: ukungangqinelani kwezinto, ukuqhekeka kwenkqubo, kunye neempazamo ze-handoff ebanzi. Siwavala ngabom.
Okokuqala, ulawulo lwezinto ezikrwada alukho malunga nezatifikethi-zimalunga nokulandelelwa kwinqanaba le-batch ukuya kwi-melt log. Xa ukhankanya ingxubevange esekwe kwi-cobalt ye-T800, sifumana kubathengisi abasele beqeqeshiwe ababonelela ngeengxelo ezipheleleyo ze-spectrographic *kunye* nedatha yembali yobushushu kwiqashiso le-ingot nganye. Akukho chemistry "eqhelekileyo". Akukho ntelekelelo "njengokuphoswa". Yonke into egalelwayo ingqinisiswa ngokuchasene ne-AMS 5387 yeegophe zepropathi zoomatshini-hayi nje amandla okuqina, kodwa ubude bokwaphuka kunye nokuqina kobunzima kuwo wonke amacandelo obungqingqwa.
Okwesibini, ukudibanisa ngokuthe nkqo kuphelisa ukupakishwa kokunyamezela okubulala iindawo ezichanekileyo. Ukuchithwa kwesanti kukodwa akukwazi ukubamba ± 0.15 mm kwizindlu ze-cylinder ezingama-400 mm. Kodwa xa iqela lethu le-Foundry lidibanisa iinkqubo ze-gating kunye neenjineli ze-machining-kwaye omabini amaqela ahlaziya ingxelo efanayo ye-CMM kwipatheni yesanti eluhlaza-sisusa i-loops yokuvuselela. Umgca wethu wokuphosa utyalo-mali uphatha iipaseji eziyinkimbinkimbi zangaphakathi kwiivalve zoxinzelelo; umgca wethu wesanti uvelisa iziseko zempompo ezinkulu ukuya kuthi ga kwi-1,200 kg-zombini zondla ngokuthe ngqo kwiiseli ze-CNC ze-axis ezintlanu apho iibhorethi zokugqibela, iindawo zokutywina, kunye nobuso obunyukayo bulungiswa ngokuseta enye.
Okwesithathu, ukuhlolwa akusiyo indawo yokukhangela-kukuqinisekiswa okuqhubekayo. Izinto ezingenayo zifumana i-spark spectrometry kunye novavanyo lwe-ultrasonic. Ukuhlolwa kwenkqubo kusebenzisa ii-CMM ze-Zeiss ezineprobes ezilungelelanisiweyo kwiidatha ezibalulekileyo, kunye nokuthelekiseka okubonakalayo kweempawu ezibuthathaka kwiprofayili efana ne-nozzle orifices. Uhlolo lokugqibela lubandakanya uvavanyo loxinzelelo olusebenzayo (ukuya kuthi ga kwi-bar ye-500), ukungena kwedayi kwiziphene ezingaphantsi komhlaba, kunye nokuqinisekiswa koburhabaxa bomphezulu ngokwe-ISO 4287-ebhalwe kwidosi yokulandeleka epheleleyo ebotshelelwe kwinxalenye yeenombolo ze-serial.
Apho iziseko zomgangatho ziye zayeka, ukugaywa ngokuchanekileyo kuyaqala
Abanye banokuphikisa: "Umatshini weCNC unikezela unyamezelo olungqongqo kunokuphosa-ke kutheni uphoswa kwaphela?" Iyasebenza—kodwa ayiphelelanga. Ukucoca indlu yempompo yepiston engama-300 mm ukusuka kwinkunkuma yentsimbi eqinileyo engama-78% yemathiriyeli ekrwada, kubangela uxinzelelo olushiyekileyo, kunye nomngcipheko wokuphazamiseka ngexesha lonyango lobushushu. Ukuphosa imilo ekufutshane nenetha emva koko ukugqiba umphezulu obalulekileyo kuphela kusika ixesha lokukhokela ngama-40%, kunciphisa umahluko wobunzima phakathi kweebhetshi, kwaye kugcina ukuhamba okuziinkozo okuya ngakumkhomba ukuxhathisa ukudinwa.
Umahluli wokwenene? Ukuphatha oko abanye balayo. I-cobalt-nickel alloys efana ne-AMS 5387 ayinzima nje kumatshini-ayizinzile ngokushushu. Ukushisa kakhulu ngexesha lokugaya? I-oxidation yomda wokuziinkozo itshabalalisa ukuxhathisa umhlwa. Uphole kakhulu ekusaseni? Iifom ze-Micro-porosity kwiinguqu ezityebileyo ukuya kwi-thin. Siqhuba isoftware yokulinganisa i-thermal kuyo yonke inxalenye entsha yejometri, sihlengahlengisa amaxabiso okupholisa ngexesha langempela sisebenzisa i-thermocouples efakwe ngaphakathi, kwaye siqinisekisa i-microstructure kunye ne-metallographic cross-sections-hayi nje kumanqaku okuqala, kodwa ngekota kumaqashiso emveliso.
Awona macandelo acelwe kakhulu ayayingqina: izindlu zepiston pump cylinder ezinobunzulu <0.03 mm ngaphaya kwe-600 mm ubude; iirola ze-winch centre shaft ezineendawo zokunxiba eziqinileyo ezidibana ne-ASTM A957 yeBanga le-100 ye-tensile specs; iiplagi zecobalt ezingekho mgangathweni ezinemijelo etywiniweyo ephindwe kabini efuna ± 0.015 mm ububanzi bomsele kunye nokugqiba kweRa 0.4 μm. Ezi ayizozinto zekhathalogu. Zizisombululo ezinobunjineli-apho iiparamitha zokuphosa, imijikelo yonyango lobushushu, kunye nezicwangciso zobuchule zidityanisiwe ukusuka kuSuku lokuQala.
Uvavanya njani umzi-mveliso wesiseko ochanekileyo ochanekileyo
Buza le mibuzo mithathu-kwaye ujonge ukuba iphendula njani:
- "Ndibonise iingxelo zakho zokugqibela ezintathu zeCMM zenxalenye ene-GD&T callouts eqinile kune ±0.05 mm." Ukuba bayathandabuza, okanye babelane ngeetemplates eziqhelekileyo, hamba. Iivenkile zokwenyani zigcina oovimba bedijithali abapheleleyo.
- “Ukulawula njani ukucutheka kudonga oluyi-12 mm olukufuphi nomphathi oyi-45 mm?” Iimpendulo ezingacacanga malunga “noyilo olungundoqo” luphawu lokuqikelela. Iivenkile ezichanekileyo zibhekisa kwiziphumo zemodeli ye-thermal kwaye zibonisa i-delta elinganisiweyo phakathi kwe-cast-cast kunye ne-post-HT yemilinganiselo.
- "Lithini izinga lakho lokulahlwa kwe-AMS 5387 kwiinyanga ezili-12 ezidlulileyo-kwaye yintoni eyona nto iphambili yokusilela okuthathu?" Ukungafihli apha kwahlula amahlakani kubathengisi.
