Xa sithethaukuphosa ukufa, kukho iinkqubo ezimbini ezilandelwayo - i-HPDC (i-High-Pressure Die Casting) okanye i-Gravity die casting (i-Low-Pressure Die Casting). Bobabini bajongana neemeko ezahlukeneyo kodwa basebenzise inkqubo efanayo ukufikelela kwisiphumo sokugqibela.

Ukuphoswa komxhuzulane kukufa yenye yeenkqubo zokuqala zokuphosa ezayilwa ngabantu. Ngokuhamba kwexesha, ifumene uphuculo olukhulu ngokubhekiselele kwisixhobo kunye nokusebenza kakuhle kwenkqubo.

Kweli nqaku, sixoxa nge-gravity die casting, iingenelo zayo, kunye nenkqubo yayo.

Inkcazo yomxhuzulane die cast

Gravity die casting luhlobo lwenkqubo yokuphosa ifa eluncedo kwimveliso yothotho olukhulu. Ifumana ukusetyenziswa kumashishini aliqela ngenxa yeendleko ezincinci kunye nemveliso ekumgangatho ophezulu eyifikelelayo ngophazamiseko oluncinci lomntu. Inkqubo isetyenziselwa iindawo zengxubevange ezingenayo i-ferrous, ngokuqhelekileyo i-aluminium, ubhedu, kunye ne-zinc-based.

Inkqubo yanamhlanje yokuphosa i-gravity die i-automation ukuya kwinqanaba elikhulu. Ifaneleka kakhulu kwiindawo ezinkulu, ezishinyeneyo ezifuna amanqanaba aphezulu eenkcukacha. Iimveliso ezivela kule nkqubo zinika ukugqiba okuphezulu kunye neempawu zoomatshini xa kuthelekiswa nokuphosa isanti. Ikwanalo nesantya esiphezulu sokuphosa xa kuthelekiswa nokugalelwa kwesanti ye-aluminiyam.

Yahluke njani kwi-high-pressure die casting?

Ukuphoswa koxinzelelo oluphezulu kusebenzisa uxinzelelo emva kokutofa ulwelo kwidayisi. Ifuna oomatshini abantsonkothileyo kwaye ilandela inkqubo ezenzekelayo ngokupheleleyo ukufezekisa umphumo. Ukuphosa ukufa komxhuzulane akuyonkqubo ezenzekelayo ngokupheleleyo, ekhokelela ekuguquguqukeni okuphantsi. Umxhuzulane die casting kwakhona zitshiphu ezimbini.

Usetyenziso lomxhuzulane lufayo

I-Gravity die casting ifumana ukusetyenziswa kumashishini amaninzi, njengezixhobo zasekhitshini, iimoto, izinto zokukhanyisa, kunye nezinye, ezineemeko ezininzi zokusetyenziswa. Kukulungele ukuvelisa iinxalenye, ezifana ne-knuckles, iintloko ze-cylinder ze-injini, iibhloko zeenjini, iipistons, njl.

Inkqubo yokuphosa i-Gravity die

I-Gravity die casting ithandwa kakhulu ngenxa yendlela yayo engena-clutter kwaye ithe ngqo ngokuthelekisayo. Ifuna ubuncinci oomatshini, kwaye ungalungisa imveliso ukuya kumda. Ukuba ujonge imiqulu ephezulu, unokwenza ngokuzenzekelayo inxalenye ebalulekileyo yenkqubo.

Nazi izinto ezibandakanyekayo kwinkqubo yokuphosa ukufa komxhuzulane -

1. Ukulungisa idayisi

Inkqubo iqala ngokufudumeza ukufa usebenzisa izitshisi zegesi kunye nokutshizwa ngengubo ephikisayo. Ingasetyenziselwa amaxesha amaninzi kwaye inceda ekususeni ukuphosa. Ikwalawula amanqanaba obushushu. Emva koko iinxalenye zokufa ziyadityaniswa kwaye zibotshwe.

2. Inaliti yolwelo

Umsebenzisi ugalela isinyithi esinyibilikisiweyo kwidayisi. Isinyithi se-liquid sishiywe ukuseta kwaye sithathe imilo ye-cast iiyure ezimbalwa. Kwi-gravity die casting, umqhubi womatshini usebenzisa ukugalela okuphantsi, kwaye ugcwalisa ulwelo usebenzisa i-sprue ezantsi.

3. Ukukhutshwa

Emva kokuba isinyithi sisethiwe, idiyizi iyavulwa, kwaye bayayikhupha i-castings. Inxalenye elandelayo ibandakanya ukususwa kweengxenye eziphosiweyo kunye nezikhonkwane ze-ejection ngesandla. I-scrap, kubandakanywa namasango, i-sprues, iimbaleki kunye ne-flash, ziyasuswa kwi-cast.

4. Shakeout kunye nokupolisha

Iicastings ke ziyabotshwa kwaye ziphathwe ubushushu (naphi na apho kuyimfuneko). Ukucutshungulwa kunceda ekususeni nayiphi na imiphetho ebukhali kunye nezinto ezigqwesileyo. Inkqubo yokugqibela ibandakanya ukucocwa kokuqhuma ukunika ipolisi efunekayo kwiimveliso zokugqibela.

Iingenelo

Nazi izizathu zokuba kutheni ukuphoswa komxhuzulane kukufumana ukuthandwa kakhulu -

• Yenye yeenkqubo ezonga kakhulu zokuphosa ukufa
• Iluncedo kwii-castings ezilula, ngokukhethekileyo ezincinci, ezinobunzima obufanayo bodonga kwaye akukho bunzima
• Ukuchaneka okuhle komgangatho kunye namaxesha okuvelisa akhawulezayo
• Eyona nto ifanelekileyo kumanqanaba aphezulu omthamo
• I-coating ingasetyenziselwa amaxesha amaninzi kwaye ifuna utyalo-mali oluncinci xa utyalo-mali lokuqala lukhona
• Inokuvelisa iinxalenye ezineempawu eziphezulu zomatshini (ezifana nerhasi ephantsi kunye nengqolowa ecolekileyo) eyona ilungele unyango lobushushu.
• Imveliso yokugqibela ifuna ukugqitywa okuncinci kunye nokubanjwa ngenxa yeenzuzo zayo zendalo

Songa

Kukho izinto ezininzi ekufuneka ziqwalaselwe phambi kokuba wenze isigqibo malunga nengokuchanekileyo die castinkqubo oyikhethayo. Ibandakanya iimfuno zomgangatho ezifana nobunzima, ingqibelelo, ukugqiba umphezulu, kunye neempawu zomatshini. Kufuneka kwakhona sithathele ingqalelo ixesha lokukhokela, izinga lemveliso, kunye neminye imiba yorhwebo. Izinyithi ezineendawo eziphezulu zokunyibilika azikho ezona zilungileyo kumxhuzulane wokuphosa.
