Xa iinjineli zichaza i-silicon ukubunjwa kwefektri yokuphosa iinkonzo zezixhobo zetsimbi eziphezulu, azigcini nje uku-odola iinxalenye-zikhusela ukuzinza kwe-dimensional phantsi kwe-300 MPa imithwalo ye-hydraulic, ukuqhubeka kwe-microstructure emva kokunyanga kobushushu, kunye nokunyaniseka kwendawo ehlala i-slurry e-abrasive kwiimpompo ze-oilfield. Leyo yinyani yokusebenza emva kokuphosa ngokuchanekileyo namhlanje-kungekhona ukunyamezela kwethiyori kumzobo, kodwa ukusebenza okunokulinganiswa kwinkonzo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza enye yezibonelelo ezimbalwa zemveliso e-China apho ukubunjwa kwesilicone (uhlobo oluthile lotyalo-mali kusetyenziswa amaqokobhe e-ceramic ase-silica-based) kusetyenziswa ngokucwangcisiweyo kwi-cobalt-nickel alloys njenge-AMS 5387 kunye ne-T800. Siye saphosa phezu kwe-12,000 imizimba yevalve yoxinzelelo lwe-subsea hydraulic control units ukususela ngo-2021-nganye ifuna i-± 0.05 mm ebalulekileyo ye-concentricity, i-porosity yangaphakathi ye-zero nge-ASTM E192, kunye nokulandelelwa ngokupheleleyo ukusuka kwi-alloy lot ekrwada ukuya kwingxelo yokugqibela ye-CMM. Loo nqanaba lokuhambelana akwenzeki ngamabona-ndenzile. Kwenzeka xa ukuphosa kungahlukaniswanga kumatshini, unyango lobushushu, okanye ukuqinisekiswa kwe-GD&T-kwaye xa ibhetshi nganye iqala ngezatifikethi zezinto eziqinisekisiweyo, hayi iziqinisekiso zababoneleli.
Izigqibo ezithathu zobuchwephesha zahlula ukubunjwa kwe-silicon esebenzayo ekubunjweni okwamkelekileyo-kwaye ezi zichaza ukuba abathengi bavavanya ntoni ngokwenene kulingo lwasendle:
- Ulawulo lokwakheka kweqokobhe: Izibophelelo ze-silica sol eziqhelekileyo ziqhekeka ngaphezu kwe-1,100 ° C ngexesha lokugalela i-cobalt alloy. I-QINGDAO I-QIANGSENYUAN isebenzisa i-silica ye-colloidal elungisiweyo + i-silica edibeneyo ye-silica aggregate system elinganiswe kwi-1,280 ° C-iqinisekisiwe ngohlalutyo lwe-thermal gravimetric kwi-shell lot. Oku kuphelisa ii-microfissures ezithi kamva zibonakalise njengokudinwa-ukuqala i-voids ebusweni kwizindlu ze-cylinder zepompo.
- Ulawulo lokuqiniswa kolwalathiso: Kwizindlu zepiston pump cylinder ezinoguqulo eludongeni lwe-42 mm, silungelelanisa iicastings kwi-17 ° ukusuka ngokuthe nkqo kwiziko kwaye sisebenzisa iipleyiti ezibandayo zendawo kwindawo engqindilili. I-X-ray tomography iqinisekisa ukuhamba okuziinkozo okuhamba phambili kuhambelana ne-vectors yoxinzelelo-ibaluleke kakhulu kwii-AMS 5387 iinxalenye ezisebenza kwi-450 ° C.
- Ukutshixa imvulophu yobukhulu be-Post-cast: Ngokungafaniyo nokuphosa kwesanti, ukubunjwa kwe-silicon kubambe imilinganiselo eqinile njenge-cast-kodwa kuphela ukuba izibonelelo zomatshini zenziwe ngepatheni, kungekhona ukuqikelela. Iqela lethu lakha i-0.3-0.5 mm yesitokhwe kwindawo yokutywina ebalulekileyo, emva koko iqinisekise ukugqwetheka kwangemva komatshini kunye nokulungelelaniswa kwe-laser tracker kwiindawo ezixhonywe kwi-fixture. Abathengi banika ingxelo nge-40% yokukhatywa kwenqaku lokuqala kwii-winch center shaft rollers ngenxa yoku.
Abanye banokuxoxa ukuba ukwenziwa komatshini we-CNC kuphela kuzisa ukuchaneka okungcono kunokuphosa. Kodwa oko kuphosakele i-physics: ukwenza i-120 kg ye-T800 ye-alloy block ibe yi-22 kg yesiseko sempompo ilahla i-82% yeendleko zempahla-kwaye yazisa uxinzelelo olushiyekileyo olubeka esichengeni ubomi bokudinwa kumthwalo we-cyclic. Ukwenziwa kokungunda kwe-silicon kuqalisa ukumila kufutshane nomnatha. Emva koko amaziko ethu adibeneyo e-5-axis milling asusa kuphela into efunekayo-ukugcina isakhiwo sokutya okuziinkozo, ukuphelisa amanyathelo okunciphisa uxinzelelo, kunye nokunciphisa ixesha lokuhamba ngeeveki ze-3.7 ngokuchasene neendlela ezisebenza ngokupheleleyo. IOEM enye yaseMntla Melika yatshintshela umgca womlomo we-cobalt wengxubevange kule nkqubo yomxube yaze yanciphisa iindleko zeyunithi ngama-29% ngelixa isongeza ubomi benkonzo ukusuka kwi-8,200 ukuya kwi-14,600 yeeyure zokusebenza.
Yintoni abathengi abahlala beyibuza-kwaye into esiyiphendulayo ngaphambi kokucaphula-yindlela yokuphepha iindlela ezintathu zokusilela eziqhelekileyo kwi-alloy high-alloy silicon mold castings:
- I-Microshrinkage kwiindawo ezidityanisiweyo: Isonjululwe ngomzekelo we-thermal we-gating systems kunye ne-real-time melt yokubeka iliso lokushisa (± 1.5 ° C) ngexesha lokuthulula-akukho ngaphandle.
- Ukungangqinelani koburhabaxa bobuso: Isonjululwe ngomjikelo wokudipha weqokobhe oluzenzekelayo olulungelelaniswe kwi-viscosity, i-pH, kunye nokusabalalisa ubungakanani besuntswana-hayi ukuziva komsebenzisi.
- Idimensional ikhukuliseka kwiibhetshi: Ikhuselwe ngokugcina iipateni eziphambili kwisixhobo se-Invar esizinzile kunye nokuqinisekisa ijiyometri yangaphakathi yeqokobhe kunye ne-optical profilometry pre-assembly.
Asikuthathi ukuphosa njengenkqubo ezimele. Wonke umsebenzi wokubumba i-silicon uphononongwa ngobunjineli ngaxeshanye: Ngaba inxalenye yejometri ilungiselelwe ukuqina komkhombandlela? Ngaba umjikelo ochaziweyo we-AMS 5387 wonyango lobushushu uyahambelana nobungakanani bokutya okuziinkozo obuqinileyo? Ngaba i-Ra 0.4 μm efunekayo ingagqitywa ngaphandle kokusila okwesibini okubeka ingozi kumonakalo ongaphantsi komhlaba? Ezi ayizozinto zoluhlu lokutshekisha. Ziincoko-zibhalwe, zibhalwe umhla, kwaye zincanyathiselwe kumyalelo womsebenzi.
Ukujonga phambili, i-bottleneck yokwenyani ayingomthamo-bubunzulu besatifikethi. Kunyaka ozayo, i-QINGDAO QIANGSENYUAN yandisa i-ISO 13485 ububanzi ukuze igqume amacandelo olingo lwe-cobalt-chromium yamathambo, kwaye iqalisa ukuqinisekiswa komntu wesithathu wenkqubo yokubumba i-silicon ngokuchasene ne-NADCAP AC7118 Rev. Ngoba? Kuba abasebenzisi bokugqibela abasamkeli "isebenzile okokugqibela." Bafuna ukuphindaphindwa okubhaliweyo-kuzo zonke izixhobo, iijometri, kunye nokuqhutywa kwemveliso. Xa wakho i-silicon ukubunjwa kwefektri yokuphosa inokuhambisa iipompo ze-AMS 5387 kunye ne-metallurgical traceability epheleleyo, iimpawu ezibalulekileyo ze-CMM eziqinisekisiweyo, kunye neengxelo ze-zero ezingahambelaniyo kwiinyanga ze-18 ezilandelelanayo, uyeka ukuba ngumthengisi. Uba sisiseko.
