Ngaba umgangatho uphela wezinto ezifihlayo? Isicwangciso sokuphendula kwiziphene ezintathu ezinkulu 'ezinqabileyo zichazwa ngokupheleleyo! ​

Kwinkqubo yemveliso yomzi-mveliso osisiseko, ukulahla iziphene bekusoloko kuyingxaki enkulu kwiingcali. Ezi ziphene zingachaphazeli kuphela umgangatho wemveliso, kodwa kunokubangela ilahleko yoqoqosho. Namhlanje, siya kuthatha izizathu zeziphene eziqhelekileyo zokuphosa kwaye zibonelela ngezisombululo ezifanelekileyo.

I-01 yokuphosa i-shrinkge cavity

Isizathu esingundoqo se-shrinkage sisiseko sokungafaniyo ngexesha lenkqubo eqinisiweyo ye-alloy, kunye nokuqulunqwa kwe-pores ngenxa yokupheliswa kweegesi kwi-gesestene kunye nokukhutshwa kweegesi ngexesha lokuqina. Ukudityaniswa kwezi zibini kukhokelela ekuqulunweni kwee-shrinkige ze-shrinkige kwindawo yokugqibela yoqinileyo (njengendawo eshushu).

Isicwangciso sokuphendula esichanekileyo

I-1. Ukongezwa kwesayensi kunye nokuhambelana

Cwangcisa ngokufanelekileyo (iibhola zegolide) kwicandelo elishushu okanye indawo yokugqibela yokuqinisa ukubonelela ngeendlela zolwelo.

2. Yandisa inkqubo yokuthulula

Yandisa indawo yokutsala yecandelo lenkqubo yokuthulula (yonyusa ububanzi besitayile sokuphosa) okanye unciphise umgama ophalazelayo (fihla ubude besitisha sokuphosa, kwaye ulinciphise ixesha lokuqiniswa.

3. Qinisekisa ulwelo olungaphezulu lwensimbi

Ngokufanelekileyo ukonyusa inani lokutya kwentsimbi ukuqinisekisa ukuba ulwelo olungaphezulu lwensimbi ukubuyekeza i-shrinkage.

4. Ulawulo oluhle lwentsimi yobushushu

Misela indawo yokupholisa (itshaneli yokupholisa) kwingcambu yejelo lokuphosa ukukhawulezisa eso siko kwaye uthintele isakhiwo esivela kwi-tennel.

I-5. Yandisa indlela yokutshaja

Xa uyila i-Sprue, uphephe ifuthe elithe nkqo lwentsimbi etyhutyweyo kwi-callity yodonga lwe-cavity kwaye usebenzise i-sprueds okanye i-sprued spries yokufezekisa ukugcwaliswa komoya okugudileyo kunye nokunciphisa ukufunyanwa komoya.

I-02 yokuqaqamba komgangatho

Ubunzima bomphezulu wokuphosa ikakhulu bubangelwa yimeko yemicroscopic yendawo ye-cavity kunye nokuphendula emzimbeni okanye yekhemikhali enokuthi yenzeke phakathi kwentsimbi kunye nezinto ezibonakalayo (ezibonakalayo) kubushushu obuphakamileyo.

Specific incentives include:

1. Amasuntswana ezinto zokubamba zibambi kakhulu; 2. Inkqubo yokugqobhoza iyabetha ngokukhawuleza, ibangela ukukhutshwa kwamanzi; 3. Iqondo lobushushu elinganelanga okanye ixesha elifutshane lokuphulula, amandla olawulo oluphantsi okanye amandla aphezulu aguqukayo; I-4. Ukuxinwa kwentsimbi ye-molten okanye iqondo eliphezulu lokubumba 5. Iqondo lobushushu lasekuhlaleni leMnyama ayilingani (iphezulu kakhulu).

Isicwangciso sokuphendula esichanekileyo

I-1. Ukulawulwa ngokungqongqo

Khetha izixhobo ezisemgangathweni ezisemgangathweni ezinobungakanani obufanelekileyo.

2. Ukulinganisa inkqubo yokuqhekeka

Ngokungqongqo ulawule ijika eliqaqambileyo, ngakumbi ngexesha lokufudumeza, elimele licotha kwaye likhululwe, kwaye lisuse ngokupheleleyo umswakama kunye negesi. Kwi-phosphate ye-phosphate ye-phosphate, kuyacetyiswa ukuba ugcine ubushushu obuzinzileyo ngaphakathi kuluhlu lwe-800-900 ℃ kunye nokuqinisekisa ixesha lokufakwa elaneleyo.

I-3. Yandisa inyibilikisi kunye neqondo lobushushu

Ngokuchasa ngokuchanekileyo iqondo lokunyibilika lentsimbi yokuphepha ukugxeka; Lungelelanisa ngokuvakalayo ubushushu bokwamba ngaphambi kokungena kwiziko.

I-4. Phucula umphezulu we-cavity

Faka isicelo somanzi olwahlula-hlulo kunye nobushushu obunganyangekiyo obunganyangekiyo (i-antiy evuthayo kunye nolwelo) ngokulinganayo kumphezulu we-wax (utyalomali) ukunciphisa i-adhesions kunye ne-mold cavity.

I-5. Thintela uxinzelelo olushushu

Lawula i-shrinkage cavity ukuphepha umhlaba ongalinganiyo obangelwe kukudakumba kumphezulu we-tishu.

I-03 yokuqhekeza

Xa kufikwa ekuphoseni ukuqhekeza, indlela yayo inzima kakhulu, kodwa zimbini izinto ezixhaphakileyo zokuqhekeka: Ukuqhekeka okubandayo / okushushu okubangelwa kukuqhekeka okuphezulu koxinzelelo.

1. Isimo esikhawulezayo sikhokelela ekubalekeni / kokuqhekeka okushushu: i-nyibila i-iron iyasilela ukuphelisa i-fuse ngokupheleleyo kwi-mold, eyenza amalungu abuthathaka. Oku kunxulumene ngokusondeleyo nezinto ezifana nesakhiwo se-wax (ezinjengobukhulu benkqubo), yoyilo lwenkqubo (isikhundla kunye nobungakanani besixhobo sokugcwalisa i-ping esifakelweyo esithintela ukukhutshwa kwegesi.

2. Iqondo lobushushu obuphezulu lokuqhekeza: Izinto ezifana nobushushu obugqithisileyo, amandla obushushu obuphezulu ye-Alloty (i-Special Fropt ye-Alloty ngokwayo (njl., Khokelela ekuphoseni ngenkqubo yokupholisa.

Isicwangciso sokuphendula esichanekileyo

I-1. Yandisa iiparamitha zenkqubo

Ukunciphisa ubushushu bokuphosa kwentsimbi etyhidiweyo ngokufanelekileyo.

Izixhobo ezi-2 ezikhethiweyo

Kwindawo yokuhlangana nentlanganiso yamandla, kufuneka inikezwe ekusebenziseni izixhobo zokusebenza ngamandla amaqondo obushushu aphakathi, athelekiseka kakuhle, kunye nokuphembelela okuhle. Ngamanye amaxesha, izixhobo zokusebenza ezinamandla ezinamandla zinokunciphisa uxinzelelo ngokulinganisela "ukuvelisa".

3. Khetha ngononophelo izabelo

Zama ukukuphepha ukusebenzisa izabelo kunye nobushushu obuphakathi kunye nokungasebenzi kakuhle (ezinjenge-Kickel Chromium ye-Alromium kunye ne-Cobalt Chromium ye-Alloss), ingakumbi kumacandelo aphezulu kunye nomahluko omkhulu kubungqingqwa obunzima. Khetha izabelo ngeplastiki ezingcono.

I-4 yoyilo

Ukuphucula ubume be-wax (njengokudibanisa utshintsho olujikelezileyo), qesha uyilo lwenkqubo yokuthulula (ukuqinisekisa ukuzaliswa okugudileyo, ukudinwa okwaneleyo, kunye nokupheliswa okunempumelelo, kunye nokupheliswa okuthandekayo).

Xa usenza le miqobo mihlanu iphambili, ngaba uziva ngathi indlela yokuphosa iqaqambe ngokukhawuleza kwiphanyazo?
