Lost wax thusi - indlela le nqubo isikhathi esiningi

Inqubo lapho Ukusakazwa etholwe usebenzisa khulula metal ekubunjweni inqubo okuyinto isebujameni ezibunjiwe, oyifisayo ekhethekile, ubizwa ngokuthi "utshalomali ekubunjweni".

kakhulu Inqubo ubuchwepheshe ngempela eziyinkimbinkimbi. Okokuqala udinga ukwakha master imodeli ekhethekile, okuyinto uhlobo prototype uzobe elicibilikile, t. E. Ingabe ukukhonza njenge-reference iphuzu ohlangothini liyobaqondisa ukuthuthukiswa.

Ukuze wenze imodeli master, ochwepheshe ngokuvamile zisebenzisa izinto ezifana izinkuni ayibhade. I ziyizibonelo ezinhle kanjani zokulingiswa kungavela phambili futhi kakade akhiqizwa omunye umkhiqizo isitshalo. Isinyathelo esilandelayo - ukudalwa matrices zesikhunta. Bamane kudingeka afeze umjovo ekubumbeni.

Isikhunta ngokuvamile egcwele tallow noma emakhilayoni, ngoba lezi zinto zinomswakama plasticity, okuvumela okukhiphayo ukuze uthole zonke izinhlobo amafomu.

Okulandelayo, kudingeka ancibilike ngesimo egumbini entsha - ukusebenza. It is etholwe indlela ukuncibilika. Yingakho nqubo ibizwa ngokuthi "walahlekelwa-wax ekusakazeni."

Ekubunjweni yena ngesikhathi esifanayo uhlala igobolondo adalwe kusuka Ukwakheka ekhethekile uyakwazi withstanding okushisa aphezulu kakhulu, okuyinto imodeli icutshungulwe ngokucophelela ngaphambi kokugcwalisa inqubo. Ngokwe-abasebenzi solidification ekupheleni adiliza fomu.

Ngo utshalomali ezivamile asakazwe wax noma stearin isuswe ngamanzi ashisayo. Amagobolondo okuyinto etholakala ngokuzikhandla kule nqubo, bese isinyathelo calcination kukhona ngokulandelana bathulula metal esibunjiweyo. Calcining igobolondo uyabaselwa okushisa ngokuvamile esingeqile 900 degrees Celsius, okuvumela ukuba ukuxazulula inkinga kokuthola organic compounds lichaza ekwakheni, uma kwesokunxele uncorrected, okungase kunganciphisa izinga okukhiphayo umkhiqizo.

Endaweni ehlukile, ziphawuleka ukuthi igobolondo kumele kwenziwe ikhumbula ukumelana tinhlobo letehlukene tetintfo letingemadayimenshini chemical compounds.

Lokho asakazwe utshalomali ivumela ukuthi usakaze okukhiphayo, ogama mass kungaba isukela a amagremu ezimbalwa, kodwa unga - amathani amaningana. I ukushuba ohlangothini izindonga umkhiqizo kungaba njengoba kancane kwesigamu milimitha, elihlangabezana nazo zonke wamukela namazinga omhlaba.

Nge nomqondo thusi, utshalomali thusi, Ngakho-ke, it is kuhlobane ngokuqondile umqondo nasebenza ekusakazeni. Kuyinto cishe ngokuphelele Castings ezifanayo silwenza kokubili ngobukhulu futhi ngiwumqemane.

Inqubo utshalomali thusi zithandwa kakhulu kokubili eRussia futhi lonke izwe. Kukhona ngisho izilungiselelo ezithuthukile akuvumele enze umjovo ekubumbeni.

Ukuze afeze le nqubo umqolo utshalomali thusi kudinga lonke iqoqo kumadivayisi ezahlukene futhi ukufaka. inqubo kwetheknoloji ihilela ukunyathelisa okwalandela asakazwe Umumo eyenziwe ngobumba, wazesula, le refractory enamathela Ukwakheka kanye stearin ukuncibilika, ukuhlanza Castings etholwe. Zonke inqubo ngenhla echazwe kunalokho eyinkimbinkimbi futhi kukhathaza.
