Ukuchithwa kwesanti kuseyeyona ndlela isetyenziswa kakhulu yesinyithi emhlabeni jikelele-ibalelwa ngaphezu kwe-70% yazo zonke iinxalenye zetsimbi. Kodwa kumzi-mveliso wokutyhilwa kwesanti osebenzayo, candelo ngalinye lenza okungakumbi “kunokugalela isinyithi esinyibilikisiweyo kumngundo.” Inxalenye nganye isebenza njenge-node elungelelanisiweyo kwikhonkco elichanekileyo: ibhokisi enye engundoqo engalungiswanga kakuhle, isikhululo sokubumba esingaphantsi ko-compact, okanye ixesha lokuxutywa kwe-shakeout elingahambelaniyo linokuthi lihle libe ngamazinga e-scrap angaphezu kwe-12%. Siyibonile isenzeka kwimveliso emithathu eyahlukileyo yezindlu ze-hydraulic cylinder-ixesha ngalinye zilandelwa umva hayi kwi-alloy chemistry, kodwa ukonakaliswa okufihlakeleyo kwindlela iinxalenye zomzi-mveliso wokugalela isanti ujongano.
Umgangatho wokuBumba: Apho ijometri iba yinyani
Umgangatho wokubumba awuyona nje indawo yokusebenzela-yinto yokubetha kwentliziyo yokusebenza. Apha, iipleyiti zepateni zikhwela kwiitafile zetsimbi eziqinileyo kunye ne-± 0.05 mm ukunyamezela ukunyamezela. Iibhokisi ezingundoqo zihlala kwiiracks ezizinzisiweyo zobushushu (22-24°C), kuba ne-3°C drift itshintsha iresin binder cure kinetics kwiinkqubo zebhokisi ebandayo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siqhuba imigca yokubumba emibini ehambelanayo: enye iyeyokujulwa kwentsimbi ekumgangatho ophezulu njengesiseko sempompo, enye iyeyezindlu ezinomthamo ophantsi we-cobalt-nickel alloy apho i-ramming ye-manual isazisa ulungelelwaniso oluphezulu lweenkozo malunga neempawu ezinodonga olucekethekileyo. Abaqhubi basebenzisa i-calibrated pneumatic tampers-hayi ihamile-kwaye baqinisekise amandla aluhlaza kunye ne-penetrometers ephathwayo ngaphambi kokukhulula ukubumba kwi-oven yokomisa. Tsiba eli nyathelo? Uya kufumana iziphene zokutshisa kwi-AMS 5387 cobalt alloy nozzles ngexesha lokugalela, ngakumbi kufutshane neradiyi yangaphakathi engaphantsi kwe-R1.2 mm.
Ivenkile yokunyibilika kunye neSikhululo sokugalela: Ulawulo luqala kwiTephu
Amaqondo obushushu akajongwa-alawulwa. Amaziko ethu okwazisa anyibilika idatha rhoqo ngemizuzwana esi-8: ubushushu bebhafu, ukutsalwa kwamandla, ukubamba ixesha, kunye nokwakheka kwe-slag nge-spectroscopy yexesha lokwenyani. Kwi-T800 esekelwe kwi-winch center shaft rollers, sibambe kwi-1,520 ° C ± 5 ° C ngemizuzu eyi-9 ngokuthe ngqo-akukho ngaphantsi, akukho ngaphezulu-ukuqhaqha i-micro-segregations ngaphandle kwe-chromium oxidizing. Isikhululo sokugalela sisebenzisa ulawulo lokuthambeka kweladle oluzenzekelayo, hayi ukugweba komntu. Ngoba? Ngenxa yokuba ukulibaziseka kwe-0.8-yesibini phakathi kwe-tap-open kunye ne-mold contact kwandisa ukubalwa kokufakwa kwe-oxide nge-40% kwi-castings yensimbi engenasici. Silinganisa oko. Siyilandelela ngenani lobushushu. Kwaye ewe-siyabukhaba ubushushu obugqithisa i-specs yeekhemikhali kodwa sisilele kuvavanyo lwe-fluidity kwi-spiral fluidity molds.
I-Shakeout kunye nomgca wokuCoca: Apho ii-Castings zifumana iMilo yazo
Abaninzi bacinga ukuba i-shakeout "kukukhupha isanti." Ayilunganga. Kukungqinisisa koomatshini bokuqala bokuthembeka. Iitafile zethu ze-vibratory shakeout zibaleka kwi-12 Hz ngokuthomalalisa okulawulwa yi-amplitude-kakhulu iintanda eziqhekeza imizimba yevalvu yecandelo elibhityileyo; ishiya isanti ethambileyo kakhulu ivaleleke kwimijelo yokupholisa. Emva kokuxutyushwa, ukudubula kuya ngqo ekudubuleni ngamaso e-ceramic (hayi igrit yentsimbi) ye-cobalt alloys-igrit yentsimbi ifakela amasuntswana entsimbi, ibangela ukugqobhoza kwangaphambi kwexesha kwinkonzo yeoli kunye negesi. Emva koko kuza indawo yokukhangela ebalulekileyo: ukuskena okusekwe kwi-CNC ngokuchasene ne-GD&T-echaziweyo yeemodeli eziphambili. Indawo yempompo yepiston kufuneka ibambe indawo yokunyamezela kwe-Ø0.15 mm kwiindawo ezintandathu zedatum. Ukuba akunjalo, ibuyela emva-kungekhona ukuphinda isebenze, kodwa ingcambu-isizathu sokuphonononga kunye neqela lokubumba. Loo loop yempendulo inciphisa iziphene eziphindayo ngama-65% kwiiveki ezimbini.
ILebhu yoMgangatho kunye ne-Traceability Hub: Ayikuthotyelwa-Isiqinisekiso
Asiyenzi "i-QA." Sakha isiqinisekiso kuyo yonke indawo. Imathiriyeli ekrwada engenayo ithwala iingxelo zovavanyo olupheleleyo lwelitye-zingqinisiswe ngokuchasene ne-ASTM A48, A958, okanye i-AMS 5387 ngaphambi kokuba kuthulwe. Yonke into edlalwayo ifumana ikhowudi ye-QR ekhethekileyo emiliselweyo ekugqibeleni: yiskena, kwaye ubona ikhemistri enyibilikayo, iilogi zomjikelo wobushushu, iingxelo zokuhlolwa kweCMM, iimephu ezirhabaxa, kunye ne-ID yomsebenzisi ovela kwisikhululo sokubumba. Akukho phepha. Akukho zimpazamo zokukhutshelwa. Oku akusiyo i-overkill-yiloo nto abathengi baseNyakatho Melika kunye ne-EU bafuna izinto ezibalulekileyo zoxinzelelo. Xa umxhasi waseYurophu ecela ukulandelelwa phantsi kwibhetshi ye-electrode yeeplagi zabo ze-cobalt alloy, sayizisa kwiiyure ezingama-72. Akunjalo ngenxa yokuba besiyilungisile-kodwa ngenxa yokuba inkqubo yethu iyibamba ngokuyilwa.
Ukuqonda i iinxalenye zomzi-mveliso wokugalela isanti kuthetha ukubona indawo nganye ingeyiyo njengomsebenzi owodwa, kodwa njengendawo yolungelelwaniso exhomekeke kwelinye. Ukubumba kumisela ijometri. Ukunyibilika kuchaza i-metallurgy. I-Shakeout iveza isandi solwakhiwo. Ilebhu yomgangatho iqinisekisa ukusebenza kakuhle. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siyinjineli ezo ndawo zojongano-hayi nje ukuzisebenzisa. Ngenxa yokuba iivalve zoxinzelelo, izindlu zempompo, okanye i-winch shafts esebenza kwi-bar ye-350 kunye ne-200 ° C, ukunyamezela akusiyo ithiyori. Ilinganisiwe. Ifakiwe. Iqinisekisiwe.
