Uyila njani iinaliti zokukhupha iinaliti zokuvelisa iinxalenye zentsimbi usebenzisa itekhnoloji yesanti eluhlaza?

Siza kuxubusha ngokweenkcukacha ukuyila kweenaliti zokukhupha ezisekelwe kwiimpawu zobuchwepheshe besanti eluhlaza kunye neengxenye zentsimbi. Intsimbi yesanti eluhlaza ineempawu zayo ezizodwa zenkqubo, ngoko ke ukuyila kweenaliti zokukhupha nazo kufuna ingqalelo ekhethekileyo. 

Impembelelo yeempawu zesanti eluhlaza iphosa iinxalenye zentsimbi kuyilo lweenaliti zokukhupha: 

I-1 Isizukulwana esikhulu segesi esigxininisiweyo: Isanti emanzi iqulethe malunga ne-3.5% -5% ukufuma, okunyuka ngokukhawuleza phantsi kwempembelelo yobushushu obuphezulu bentsimbi enyibilikisiweyo. Kwangaxeshanye, umgubo wamalahle, izinto eziphilayo, kunye nezinye izinto ezisesantini nazo ziyatsha kwaye zivelise irhasi, nto leyo ebangela ukuba kuveliswe isixa esikhulu segesi ngoko nangoko ngexesha lokuqala lokugalelwa. 

2. Impembelelo yoxinzelelo olubi: Ngexesha lokuzaliswa kwesinyithi esinyibilikisiweyo, uxinzelelo olubi olukhawulezileyo luya kwenziwa kwiindawo ezithile ze-mold cavity (ngokukodwa kwindawo apho isinyithi esinyibilikisiweyo sizaliswe ekugqibeleni), esiya kwenza "njengetyhubhu yokufunxa", ukufunxa ngamandla igesi kwi-sand pores kunye nenaliti yokukhupha. Ukuba inaliti yokukhupha ayilwanga ngokufanelekileyo, ulwelo lwentsimbi lunokuthi "lufunxeke". 

3. Ulwelo olululo lwentsimbi etyhidiweyo: Intsimbi etyhidiweyo (ingakumbi i-iron etyhidiweyo engwevu) inolwelo oluhle kunye noxinzelelo olusezantsi xa kuthelekiswa ne-aluminiyam etyhidiweyo, ikwenza kube lula ukugqobhoza izikhewu ezincinci. 

4. Uxinzelelo oluphakathi: Xa kuthelekiswa nentsimbi etyhidiweyo, isinyithi esityhidiweyo sinobushushu obuncinci bokugalela kunye noxinzelelo lwe-static, olunika indawo ethile yokhuseleko loyilo lweenaliti zokukhupha.

Amanqaku aphambili oyilo olujoliswe kuyo lwenaliti yokukhupha iinxalenye zentsimbi yesanti eluhlaza: Ngokusekelwe kwiimpawu ezingentla apha, ingundoqo yoyilo kukubonelela indawo yokukhupha eyaneleyo kwinqanaba lokuqala lokuphosa, ngelixa lixhathisa ngokufanelekileyo i-backflow yensimbi yolwelo olubangelwa luxinzelelo olubi kwangoko. 

1. I-Exhaust groove shape: "Ukwandiswa kancinci kancinci" okanye "ukugobhoza" uyilo lukhethwayo, kunye ne-groove inclined (ukwandiswa ngokuthe ngcembe) kucetyiswa ngamandla. Inkcazo: I-exhaust groove imxinwa ngaphakathi ngaphakathi kwendawo kwaye ibanzi ngaphandle kwe-atmosfera, yenza i-taper encinci. Izinto eziluncedo: I-Anti backflow: Xa ulwelo lwesinyithi lutyhalwa ukuya kwi-groove yokukhupha phantsi koxinzelelo olubi, luya kuhamba lusuka kwindawo ebanzi ukuya kwindawo encinci, lunciphisa indawo enqamlezileyo yomjelo wokuhamba kunye nokwandisa ukuxhathisa ngokukhawuleza, ukukhusela ngokufanelekileyo ulwelo lwetsimbi ekungeneni nzulu. Ukukhupha okugudileyo: Irhasi ihamba kakuhle isuka kwindawo emxinwa ukuya kwiindawo ezibanzi, inoxhathiso olungephi. Ukusetyenzwa: Nangona ukusetyenzwa kunzima ngakumbi kunemijelo ethe tye, kunokufezekiswa ngokusika ucingo okanye izixhobo ezikhethekileyo zokusila. Kuphephe ukusebenzisa iigrooves ezilula ezithe tye: Imijelo ethe tye inokumelana nokuhamba kakubi phantsi koxinzelelo olubi kwaye ithwala imingcipheko ephezulu. 

2. Ubungakanani be-groove yokukhupha (i-parameter engundoqo), ububanzi be-groove (isitshixo phakathi kwesitshixo): Uluhlu olucetyiswayo: 0.15 mm ~ 0.25 mm. Umgaqo womda ophezulu: Kwintsimbi eluhlaza esantiweyo yesanti, ububanzi bomsele akufunekanga budlule kwi-0.25mm. I-0.20mm yisayizi esetyenziswa kakhulu kwaye ikhuselekile. Obu bubanzi busebenzisa ukuxinana komphezulu wentsimbi enyibilikisiweyo, yenze kube nzima ukuba ihlasele ngokuzenzekelayo, ngelixa ikwabonelela ngokumelana okwaneleyo phantsi koxinzelelo olubi. Ukuba i-casting inzima, uxinzelelo lwe-static luphezulu, okanye isikhundla sibaluleke kakhulu (njengeyona ndawo iphakamileyo ye-mold cavity), ubungakanani obuncinci kufuneka bukhethwe, njenge-0.15mm okanye i-0.18mm. Ubunzulu beGroove: Uluhlu olucetyiswayo: 0.4 mm ~ 0.8 mm. Ukuqinisekisa ukukhutshwa okwaneleyo kwendawo enqamlezileyo, ubunzulu be-groove budla ngokuphindwe ngama-2-4 ububanzi be-groove. Ngokomzekelo, ububanzi be-slot ye-0.20mm buhambelana nobunzulu be-slot ye-0.5mm-0.8mm. Ubude bendawo yokubeka (ubukhulu bodonga lwenaliti yokukhupha): Uluhlu olucetyiswayo: 20 mm ~ 30 mm. Ubude obaneleyo bunokwenza 'icandelo lokumelana nokuqukuqela' elizinzileyo, okonyusa ukuxhathisa kokukhuhlana kokuhamba kwesinyithi esinyibilikisiweyo kwaye kuyivumele ukuba yomelele phambi kokufikelela kwicala le-atmosfere. 

3. Inani kunye nokuhlelwa kweendawo zokukhupha i-slots: ngokuqhelekileyo i-4 ukuya kwi-8, isasazwe ngokulinganayo kwi-circumference. Uyilo: Kuyimfuneko ukuqinisekisa ukuba umbhobho wokukhupha udityanisiwe. Kuyilo lokwandiswa ngokuthe ngcembe, kuyimfuneko ukubonisa ngokucacileyo ukuba yeyiphi isiphelo secala lombhobho (isiphelo esimxinwa) kwaye yeyiphi isiphelo se-atmospheric (isiphelo esibanzi), kwaye ubonise kumzobo ukuba "isiphelo esincinci sijongene nomngxuma ngexesha lofakelo". 

4. Indawo yofakelo kunye nobungakanani beenaliti zokukhupha: "Indawo efileyo" kunye neyona ndawo iphakamileyo yomngxuma wokungunda zezona ndawo irhasi idla ngokuqokelelana kuyo. Ummandla ochasene nenkqubo yokugalela okanye apho intsimbi enyibilikisiweyo igcwaliswa khona ekugqibeleni: Kulapho irhasi ixinzelelwe khona kakhulu kwaye ifuthe elibi loxinzelelo libonakala kakhulu. Ukungunda okungaphezulu kolwakhiwo olukhulu olusicaba: lunceda ekususeni irhasi eqokelelwe phezulu kumngxuma wokungunda. Kufuphi nombindi: ngakumbi apho irhasi eveliswa ngundoqo wesanti ifuna ukukhutshelwa kumgodi wokungunda. Ubuninzi: Okuninzi kungcono kunengaphantsi. Iinaliti zokukhupha zingafakwa kwiindawo apho kukho ukukrokrela ukubamba umoya. Iindleko zayo ziphantsi kakhulu kunelahleko yenkunkuma ebangelwa yi-pores.

 IsiShwankathelo soyilo kunye neNgcaciso eziCetyisiweyo Kwicandelo eliqhelekileyo lesanti eluhlaza yentsimbi, imilinganiselo ephakanyisiweyo yenaliti yokukhupha ilandelayo: Izinto eziphathekayo: 45 # intsimbi, ukucima kunye nobushushu, kunye nenxalenye esebenzayo (inxalenye ye-grooved) yokucima kwi-HRC 40-45 ukunyusa ukunyanzeliswa kokugqoka kunye nokuchasana nokukhukuliseka kwesinyithi esinyibilikisiweyo. Ukubonakala: I-Cylindrical enegxalaba, i-diameter esetyenziswa ngokuqhelekileyo ye-Φ 8mm okanye Φ 10mm. I-exhaust groove: Ubume: Umsele othambekileyo (icala elimxinwa, icala leatmosfere elibanzi). Slot ububanzi: 0.20 mm (cavity icala). Ubunzulu beGroove: 0.6 mm. Ubungakanani: 6, isasazwe ngokulinganayo. Ubude bendawo: 25 mm. 

Iingcebiso ezikhethekileyo zokusetyenziswa kunye nokugcinwa: 

1 Ukuthintela ngokungqongqo ukuvaleka: Amasuntswana esanti kunye neengubo zesanti eluhlaza zinokuthi zithintele imibhobho yokukhupha emxinwa. Emva kokusetyenziswa ngakunye, umoya ocinezelweyo kufuneka uvuthelwe umva ukusuka kwicala le-atmospheri kwaye ucocwe ngocingo oluhle kakhulu lwentsimbi okanye inaliti. Rhoqo jonga ukuba ayinamqobo na. 

2. Ufakelo oluchanekileyo: Qinisekisa ukuba inaliti yokukhupha kunye nomngxuma wokubumba unombhobho wokuphazamiseka okanye ukulingana okuqinileyo, ngaphandle kokukhululeka. Isiphelo esimxinwa kufuneka sijongane nomngxuma! Emva kofakelo, kulungele ukuba ubuso bayo bokugqibela buhlanjululwe kunye nodonga lwecavity okanye luhlehliswe kancinci (<0.5mm), kwaye ugweme ukukhutshwa. 

3. Ukutshintshwa ngexesha elifanelekileyo: Emva kokuba kukho iimpawu zokhukuliseko, ukujikeleza okanye ukwandiswa komphetho we-exhaust groove ngentsimbi etyhidiweyo, kufuneka ichithwe kwaye itshintshwe ngokukhawuleza. Ukuqukumbela: Kwinxalenye yentsimbi yesanti eluhlaza, uyilo lwenaliti yokukhupha eyimpumelelo kukusebenzisa umjelo okhulayo ngokuthe ngcembe kwaye ulawule ngokungqongqo ububanzi bomsele ongaphantsi kwe-0.25mm. 

Olu luyilo alukwazi nje ukujamelana nesizukulwana esikhulu segesi kunye noxinzelelo olubi olukhawulezileyo kwisigaba sokuqala sokugalela, kodwa kwakhona lukhusela ngokuthembekileyo ukungena kwentsimbi etyhidiweyo, eyona nto ingundoqo encinci yokuqinisekisa umgangatho wokuphosa kunye nokunciphisa izinga le-scrap.
