Ukukhetha okulungileyo intsimbi Inkqubo ayithethi malunga nokukhetha igama kuluhlu. Kumalunga nokuthelekisa i-physics, ijometri, kunye nomsebenzi-ngaphambi kokuba kugalelwe isikhunta sokuqala. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sijule ngaphezulu kwe-12,000 yamacandelo awodwa kwiivalvu zehydraulic, izindlu zempompo, kunye neeshafti zewintshi elunxwemeni. Yonke into engaphumeleli yasifundisa into ephathekayo: ukuchithwa kwesanti akuyi kubamba ± 0.05 mm kwisihlalo somlomo we-cobalt-alloy; utyalo-mali ukuphosa iintanda ukuba utsiba preheat kwi AMS 5387; kunye ne-centrifugal casting lusilela ngentlekele xa ubukhulu bodonga busihla ngaphantsi kwe-18 mm kwii-cylinder liners ezinoxinzelelo oluphezulu.
Qala ngenxalenye—kungekhona inkqubo
Uninzi lweenjineli ziqala ngokubuza "Yeyiphi indlela yokuphosa intsimbi eyona ilungileyo?" Lo mbuzo ukhokelela ngokuthe ngqo kwingcaciso engaphezulu okanye ekusebenzeni ngaphantsi. Kunoko, buza izinto ezintathu: Luya kuyithwala yiphi imithwalo? Isilela phi enkonzweni? Yeyiphi imilinganiselo yokunyamezela ekufuneka isinde kumatshini wokugqibela?
Sake safumana umzobo we-T800 cobalt alloy piston yezindlu zempompo-ejoliswe ekusebenzeni kwebha ye-350. Umthengi uchaze ukugalelwa kwesanti. Kodwa emva kwemodeli yoxinzelelo lwe-thermal kunye nokuphononongwa kwe-microstructure, sicebise ukuphosa utyalo-mali ngokuqiniswa okulawulwayo. Ngoba? Ukugalelwa kwesanti kuvelise ubume obungahambelaniyo beenkozo kufutshane ne-valve port interface. Iiyunithi ezimbini zokuvavanya ziqhekezwe kwi-bar ye-280 ngexesha lovavanyo lokuqhuma. Utyalo-mali luhambise isithuba se-dendrite esifanayo, siphumelele iibhari ezingama-420 zokuqinisekiswa, kwaye kuncitshiswe izinto ezilahliweyo zasemva komatshini ukusuka kwi-37% ukuya kwi-9%.
Indawo ethathwayo: Ijiyometri iqhuba ukhetho lwenkqubo. Iikhonto ezibhityileyo, ezintsonkothileyo ezinekhwelo eliqinileyo le-GD&T lokusatshalaliswa kotyalo-mali. Iziseko zesakhiwo esinecandelo elinzima? Ukuchithwa kwesanti kuzisa ulawulo olungcono lweendleko kunye nokuzinza kwe-thermal. I-symmetry ejikelezayo kunye nobunzima bodonga obufanayo? I-Centrifugal casting inika ingxinano ephezulu kunye nobomi bokudinwa-ingakumbi kwiziseko zempompo yensimbi engenasici evezwe kukhukuliseko lwamanzi etyuwa.
Izinto eziphathekayo zichaza isilingi yakho-kunye nemida yakho
Awukwazi ukuphosa into ongenakuyondla ngayo. Ingxubevange ye-cobalt-nickel efana ne-AMS 5387 kunye ne-T800 ineendawo eziphezulu zokunyibilika (1370-1420 ° C), i-fluidity ephantsi, kunye novakalelo olugqithisileyo kwi-gradient yobushushu bokubumba. Siye sabona iivenkile zizama ukubanyanzelela kubumba lwesanti eluhlaza-kuphela ukufumana izivalo ezibandayo, ukushwabana kwe-porosity, kunye nokuqhekeka kwe-interdendritic. Ezi ayizizo "iintsilelo zenkqubo." Ziyinkqubo yezinto eziphathekayo ezingafanelekanga.
Indawo yethu iqhuba imigca emibini yokuphosa enxuseneyo: enye ilungiselelwe intsimbi kunye nentsimbi yekhabhoni (ukuphosa isanti, ukuya kuthi ga kwi-500 kg), enye inikezelwe kwi-high-alloy superalloys (i-investment casting, i-vacuum-assisted pour, i-sheed shells ceramic preheated). Kwimibhobho ye-AMS 5387, sisebenzisa i-silica-based shell shell systems preheated ukuya kwi-1050 ° C-kungekhona i-800 ° C-ukuphepha ukutshatyalaliswa kwe-thermal kunye nokuqinisekisa ukugcwala okupheleleyo kwe-mold. Olo tshintsho lweparameter enye lunqumle ukubandakanywa kwe-oxide yangaphakathi nge-63% kuphicotho lwethu lokugqibela lweenyanga ezili-18.
Musa ukucinga ukuba "intsimbi engenasici" ithetha into enye. I-316 iziphatha ngendlela ehluke kakhulu kune-17-4PH okanye i-F22. Kwaye i-cobalt alloys ifuna i-gating eyahlukileyo, ukunyuka, kunye neendlela zokupholisa kune-Inconel ezisekelwe kwi-nickel. Ukuba umthengisi wakho akakuceli ishidi lakho elipheleleyo le-metallurgical spec-kubandakanya imbali yonyango lobushushu kunye namaxabiso afunekayo e-tensile/empembelelo-usele usemva.
Ukudibanisa kubetha ukuba wedwa-ngamaxesha onke
Ukuphosa okugqibeleleyo akunamsebenzi ukuba akunakwenziwa ngomatshini ukuprinta. Sibona oku yonke imihla: umthengi u-odola isiseko sentsimbi esantiweyo, emva koko afune ±0.025 mm flatness kumphezulu we-600 × 400 mm. Akunakwenzeka ngaphandle kokunciphisa uxinzelelo kunye nokulungiswa ngokuchanekileyo. Okanye iplagi ye-cobalt ye-investment-cast-cast ifika kunye ne-0.3 mm flash kumgca wokuhlukana-emva koko iyanqatshwa ngenxa yokuba ivenkile ye-CNC ayinazo izixhobo ezincinci ze-3.2 mm zangaphakathi.
Yiyo loo nto iQINGDAO QIANGSENYUAN TECHNOLOGY idibanisa ukuphosa, unyango lobushushu, machining multi-axis, kunye nokuhlolwa kweCMM phantsi kophahla olunye oluhambelana ne-ISO. Xa sicaphula umzimba wevalvu yoxinzelelo, silinganisa ukuhamba komsebenzi wonke: ukuphosa imbuyekezo yokuncipha, ixesha lomjikelo wokunciphisa uxinzelelo, uyilo lokulungisa udonga olubhityileyo, kunye nomlinganiso obonakalayo wemigangatho yokutywina ebalulekileyo. Asinikezeli ngamacandelo-sinikezela ngezixhobo eziqinisekisiweyo zokusebenza.
Oku kudityaniswa kunciphisa ixesha elihamba phambili ngama-31% kwii-odolo zomthamo ophakathi kwaye kuphelisa i-94% yokulungiswa kwakhona kwe-dimensional. Okubaluleke ngakumbi, isenza ukuba sisombulule iingxaki phambi kokuba zibekho-njengokulungelelanisa isango lokunciphisa intsalela yoxinzelelo kwi-winch center shaft roller ukuze ukucola kokugqibela kufezekise iRa 0.4 µm ngaphandle kwencoko.
Buza imibuzo efanelekileyo-ngaphambi kokuba uzinikele
Ngaphambi kokukhetha i intsimbi iqabane, qinisekisa la manqaku mahlanu:
- Ngaba bayayiqinisekisa inkqubo yabo yokuphosa-kungekhona nje ukuhlola umphumo? Buza iingxelo zokulinganisa ukuqinisa kunye ne-thermal gradient logs kwiqashiso ngalinye.
- Ngaba bayakwazi ukulandelela yonke ibhetshi kwii-certs zemathiriyeli ekrwada-kubandakanywa neengxelo zovavanyo lwe-mill kunye nohlalutyo lwe-spectrographic? Akukho ngaphandle kwe-cobalt okanye i-nickel alloys.
- Ngaba benza inkqubo yokuhlola i-CMM kwiipateni eziluhlaza okanye ze-wax-kungekhona nje iindawo zokugqibela? Ibalulekile kwi-GD&T-indibano ezinzima ezifana nezindlu zesilinda zempompo.
- Lithini inqanaba labo lesivuno esiqinisekisiweyo kwi-alloy yakho ethile kunye nejometri? Hayi “umndilili weshishini”—eyakho.
- Ngaba bayaphonononga ukuveliswa kokwenziwa ngexesha lokukhutshwa kobunjineli-kungekhona emva kokuba kuqalwe izixhobo zokusebenza? Sifaka imingcipheko njengee-undercuts ezibambisa imathiriyeli yeqokobhe leceramic okanye iradiyi encinci kakhulu kwizikhonkwane ezingundoqo.
Akukho ndlela "yeyona" igqwesileyo yentsimbi. Kukho umdlalo ofanelekileyo kuphela-kwityala lakho lomthwalo, imathiriyeli yakho, ukupakisha kwakho ukunyamezela, kunye nefestile yokuhanjiswa kwehlabathi lokwenyani. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke into yokuphosa njengenkqubo-kungekhona icandelo. Kuba kwiinkqubo ze-hydraulic, i-oyile kunye nezixhobo zegesi, kunye neemoto zobunjineli zokuqhuba, iqela elinye le-porosity ayisosiphene sokuthambisa. Yindlela evuzayo. Imvelaphi yokudinwa. Ukusilela kwebala kulindelwe ukwenzeka.
Khetha inkqubo ehlonipha injongo yenxalenye yakho-hayi nje imilo yayo.
