Njengenkqubo yokwenza undoqo, inkqubo yesanti egqunyiweyo isabambe indawo ebalulekileyo kwimveliso yokuphosa.Nangona inkqubo yokwenza i-furan core, inkqubo yokwenza i-core ebandayo kunye nezinye iinkqubo zihlala ziphuhliswa kwaye zisebenza, inkqubo yokwenziwa kwayo engundoqo isasetyenziswa ngokubanzi kumashishini ahlukeneyo okuphosa ngenxa yobuninzi bayo obugqwesileyo, amandla aphezulu kunye nokuzinza kwe-thermal, kunye nexesha elide lokugcina.Kusenzima ukutshintsha kwamanye amashishini afana neenxalenye zehydraulic, amaqokobhe ei turbine kunye namanye amashishini akumgangatho ophezulu.
Iimpawu:
ukusebenza kwamandla okufanelekileyo;ubumanzi obulungileyo, ukubumba kwesanti kunye neentsimbi zesanti eziveliswayo zineekhonto ezicacileyo kunye nolwakhiwo oluxineneyo, kwaye zinokuvelisa iziseko zesanti ezintsonkothileyo;umgangatho womphezulu wesikhunta sesanti (engundoqo) ulungile, uburhabaxa bomphezulu bunokufikelela ku-Ra = 6.3 ~ 12.5μm, kwaye ukuchaneka kwe-dimensional kunokufikelela kwinqanaba le-CT7 ~ CT9;Ukuqhekeka okuhle, kunye ne-castings kulula ukuyicoca.
Ubungakanani besicelo
Ingasetyenziselwa ukwenza zombini iimbumba zokubumba kunye neentsimbi zesanti.Iimbumba okanye iinqununu zingasetyenziselwa kunye nomnye okanye kunye nezinye iimbumba zesanti (ii-cores);ingasetyenziselwa kuphela ukuphosa intsimbi yomxhuzulane okanye i-low-pressure casting, kodwa kunye nokuphosa isanti yentsimbi kunye nokuphosa kwe-centrifugal eshushu;ingasetyenziselwa kuphela ukuveliswa kwesinyithi kunye ne-non-ferrous alloy castings, kodwa kunye nokuveliswa kweentsimbi zensimbi.
ukwakheka
Ngokuqhelekileyo yenziwe ngezinto eziphikisayo, izibophelelo, iiarhente zokunyanga, izithambiso kunye nezongezo ezikhethekileyo.
(1) Izinto ezizimelayo ziyinxalenye ephambili yalo.Iimfuno zemathiriyeli echasayo zezi: i-refractoriness ephezulu, ii-volatiles eziphantsi, amasuntswana angqukuva ngokuthelekiswa, okuqinileyo, njl njl. Isanti ye-silica ekhuhlayo yendalo isetyenziswa ngokubanzi.Iimfuno zesanti ye-silica zezi: umxholo ophezulu we-SiO2 (i-iron cast kunye ne-non-ferrous alloy castings ifuna ngaphezu kwe-90%, kunye neengxenye zetsimbi ezifuna ngaphezulu kwe-97%);umthamo wodaka awukho ngaphezu kwe-0.3% (kwisanti ekhuhlayo)–[udaka lwesanti ehlanjiweyo lungaphantsi;ubukhulu bamasuntswana ① busasazwa kwiinombolo ezi-3 ukuya kwezi-5 ezikufutshane zesisefu;i-particle shape ijikeleze, kwaye i-angular factor ayifanele ibe mkhulu kune-1.3;ixabiso lokusetyenziswa kwe-asidi alikho ngaphantsi kwe-5ml.
(2) I-phenolic resin isetyenziswa ngokubanzi njenge-binder.
(3) I-Hexamethylenetetramine idla ngokusetyenziswa njenge-arhente yokunyanga;I-calcium stearate isetyenziswa ngokubanzi njenge-lubricant, esetyenziselwa ukuthintela i-agglomerating kunye nokwandisa ukumanzi.Umsebenzi oyintloko wesongezo kukuphucula ukusebenza kwesanti edibeneyo.
(4) Umlinganiselo osisiseko we-Component Ratio (iqhekeza elikhulu,%) Inkcazo: Isanti eluhlaza 100 Isanti yokuxubha, i-Phenolic resin 1.0-3.0 (ubunzima besanti eluhlaza), i-Hexamethylenetetramine (isisombululo se-aqueous 2) 10-15 (ubunzima be-resin), i-Calcium stearate 5-7 (ubunzima resin), Additives 0.1-0.5 (ubunzima isanti eluhlaza).1:2) 10-15 (ubunzima beresin), iCalcium stearate 5-7 (ubunzima beresin), Izongezo 0.1-0.5 (ubunzima besanti ekrwada).
Inkqubo yokuvelisa
Inkqubo yokulungiselela ikakhulu ibandakanya ukugquma okubandayo, ukufudumala okufudumeleyo kunye nokutshisa okutshisa.Okwangoku, imveliso phantse yonke ithatha ukutyabeka okushushu.Inkqubo yokwambathisa eshushu kukufudumeza isanti ekrwada kwiqondo elithile lobushushu, kwaye emva koko udibanise kwaye ugxobhoze nge-resin, isisombululo se-urotropine samanzi kunye ne-calcium stearate ngokulandelelana, kwaye emva koko upholile, utyumze kunye nesikrini.Ngenxa yomahluko kwifomula, inkqubo yokuxuba iyahluka.Okwangoku, kukho iintlobo ezininzi zemigca yokuvelisa e-China.Kukho malunga ne-2000 ~ 2300 imigca yemveliso ye-semi-automatic kunye nokutya ngesandla, kwaye kukho phantse i-50 imigca yemveliso ezenzekelayo elawulwa yikhompyutha, ephucula ngokufanelekileyo imveliso kunye nokuzinza kwemveliso.Umzekelo, umgca wemveliso ebonakalayo ngokuzenzekelayo ye-xx Casting Co., Ltd. inexesha lokutya lokuchaneka kwe-0.1 yesibini, ukuchaneka kokulawula ukushisa kwe-1 / 10 ℃, kunye nommandla wokuxuba isanti unokubonwa ngamaxesha onke ngevidiyo. , kunye nokusebenza kakuhle kwemveliso yeetoni ezi-6 ngeyure.
Izinto eziluncedo kwinkqubo
Ukuqukuqela okugqwesileyo
Iqatywe ngentlaka eqinileyo kwaye ibonakala njengesanti eyomileyo.I-fluidity egqwesileyo yeyona nzuzo yayo inkulu, ilungele ngokukodwa i-complex and small sand cores.
Umgangatho ogqwesileyo womphezulu wondoqo wesanti
Idityaniswe ngokuqhushumba kwesibhamu, kwaye umphezulu wesiseko sesanti uxinene kwaye ugudile, onokuthi uphucule ngokufanelekileyo ukugqitywa komphezulu wokuphosa.
Ixabiso eliphantsi lokwenza iqokobhe core
Inendawo yokunyibilika ephezulu kwaye ingasetyenziselwa ukwenza iqokobhe elingundoqo, ngokusetyenziswa okuncinci kwesanti, ixabiso eliphantsi kunye nokungena komoya okungcono.
Amandla aphezulu kunye nokuzinza kwe-thermal
usebenzisa i-thermoplastic phenolic resin, inamandla aphezulu kunye nokuzinza kwe-thermal, nto leyo eyinika iingenelo ezizodwa ekusetyenzisweni kwezinye iindawo ezinzima kunye ezinkulu.
Ixesha elide lokugcina ingundoqo yesanti
I-alkaline phenolic resin esetyenziswa kwisanti egqunyiweyo yi-hydrophobic, undoqo wesanti unokumelana nokufuma okuhle, akukho mfuno zikhethekileyo kwindawo yokugcina, kwaye akukho kuncipha kumandla emva kokugcinwa kwexesha elide.
Uluhlu olubanzi lwesicelo
Undoqo wesanti ogqunyiweyo ufanelekile kwiinkqubo zokugalela zonke izinto zetsimbi.
