Uhlaziyo lokugqibela: 06/23, ixesha lokufunda: 8mins

I-Die casting yindlela eguquguqukayo kwimveliso yokudala inaliti yeisitofukunye namacandelo eemoto kwizakhiwo zefenitshala.Umatshini wokuqala wokulahla yayingumatshini omncinci osebenza ngesandla owaqanjwa ngo-1838. Wathatha inyathelo loguqulo emva kokuba u-Otto Mergenthaler edale umatshini we-linotype ngo-1885, isixhobo sokuqala sokuphosa esivulekele imarike.

Inkqubo ye-die-casting yenza kube lula ukwenza izinto ezincinci kwiimilo zejometri eziyinkimbinkimbi ngokuchanekileyo.I-die esetyenziswe kule nkqubo yenziwe ngetsimbi ephezulu ekwazi ukumelana nobushushu.Idayi ineziqingatha ezibini, esinye sazo esishukumayo ngelixa esinye silungisiwe.Kukho umngxuma phakathi kwezi zimbini.Isinyithi esityhidiweyo sifakwe kulo mgodi, kwaye uxinzelelo oluphezulu lusetyenziswa kwi-die ngexesha lenkqubo.

Umatshini wokulahla

Eli nqaku liza kucacisa iinkqubo ukufa-casting ngokweenkcukacha, kubandakanywa iinzuzo zayo kunye nezithintelo kwimveliso.

Kwi-die casting, isinyithi esityhidiweyo sitofwa phantsi koxinzelelo oluphezulu kwi-mold yentsimbi ephezulu elungiselelwe into nganye kwaye isetyenziselwa ukuveliswa kwe-serial.Ngenxa yoko, iimveliso zenziwe ngokuchanekileyo ngokuphinda-phinda.Ezona zixhobo zisetyenziswa kakhulu kwi-die casting yi-Aluminiyam, iZinc, kunye ne-magnesium alloys.

Iintlobo zenkqubo yeDie-casting

1.          Igumbi elibandayo Die-casting

Umahluko kuphela phakathi eshushu-igumbi kunye negumbi abandayo kufa iinkqubo yokugalela kukuba shot-igumbi okanye umngundo akukho pre-ufudunyezwe phambi ukunyanzelwa metal otyhidiweyo kuyo ngexesha lenkqubo ebandayo-igumbi.Igumbi elibandayo liyafa ukuphosa lisetyenziselwa i-alloys eneendawo eziphezulu zokunyibilika, njengeAluminiyam kunye nobhedu.Ngaphandle koku, ezinye ii-alloys zetsimbi ezine-ferrous zingaphoswa.Le nkqubo idinga izixhobo ezongezelelweyo zokuseta, ngokuqhelekileyo iziko langaphandle kunye neleyidi yokugalela isinyithi esityhidiweyo kumatshini.

2.          Igumbi elishushu Die-casting

Ngokwesiqhelo, iindawo ezinyibilikayo ezisezantsi ezifana neZinc, magnesium, tin, kunye nelothe ziyaphoswa kusetyenziswa ukugalelwa kwegumbi elishushu lokufa.Kwigumbi elitshisayo lokuphosa idayi, ipiston isetyenziselwa ukunyanzela isinyithi esinyibilikisiweyo singene kumngxuma wokufa ngokusebenzisa i-gooseneck kunye nomlomo.Le ntsimbi etyhidiweyo ibanjwe phantsi koxinzelelo oluphezulu kwaye inokufikelela phezulu njenge-35 MPa.Emva koko, i-burner okanye i-furnace inikezelwa, eyandisa ukushisa kwentsimbi etyhidiweyo njengoko isinyithi siqina ngaphakathi kwendawo.Ekugqibeleni, isiqingatha esishukumayo sokufa siyasuswa, kwaye inxalenye yokuphosa ifunyenwe ngoncedo lwepini ye-ejector.

Kwibloko yokufa, iipaseji ezininzi zenziwe ukuququzelela ukuhamba kwamanzi kunye ne-oyile ukupholisa idiyizi njengoko isinyithi esinyibilikisiweyo sigcwalisa umngxuma wokufa.Ngokujikeleza kwamanzi kunye neoli ngexesha lenkqubo, ubomi bokufa bunokwandiswa, kwaye ixesha lomjikelo wenkqubo lingancitshiswa.

IiPros zenkqubo yokuphosa ukufa

Imveliso eninzi evela kwi-die-casting

Inkqubo ye-die-casting ineenzuzo ezininzi kwicandelo lemveliso.Olona ncedo luphambili lubandakanya oku kulandelayo:

1.  Uluhlu olubanzi lwezinto zokusebenza

Nangona i-zinc kunye ne-aluminium alloys yizona zinto ziqhelekileyo zokusebenza kwinkqubo yokufa esetyenzisiweyo kwizinga elikhulu kumashishini okuvelisa, isekela uluhlu olubanzi lwezinto ezifana nobhedu, i-magnesium, i-lead, kunye ne-alloys ye-ferrous.

2.  Iimveliso ezininzi

Elona candelo lilungileyo malunga nokuphosa ukufa kukuba inokusetyenziswa amatyeli aliqela xa usenza ngokwezifiso ukufa.Amandla aphezulu kunye ne-heat-resissive-resistant die die inokusebenza izihlandlo ezisisigidi, ezona zilungele ukuveliswa kweemveliso kunye namacandelo.

3.  Ukusebenza kwemveliso ephezulu

Ixesha lomjikelo wemveliso yokuphosa ifa liphantsi kakhulu xa lithelekiswa nezinye iindlela zokuvelisa kunye nokuphosa.Ngokuxhomekeke kwinkcazo yamacandelo kunye neemveliso, ukusuka kwi-300 ukuya kwi-800shots ngeyure.Nangona ixesha lomjikelo wamacandelo amancinci anje ngeziphu

Amazinyo anokufikelela kwi-18,000 yeeshots ngeyure.

4.  Ukugqitywa komgangatho ophezulu kunye nokuchaneka kwe-dimensional

Uninzi lweemveliso kunye namacandelo angasetyenziswa ngokukhawuleza ngaphandle komatshini owongezelelweyo okanye ukugqitywa komphezulu.Nangona kunjalo, abanye banokufuna umatshini omncinci ukususa ukungafezeki okuncinci okudalwe kumgca apho iihafu ezimbini zokufa zahlulwe ngexesha lenkqubo yokukhululwa.Ngenxa yokuba i-die-casting isebenzisa isinyithi esinyibilikisiweyo esicinezelekileyo, esinegalelo ekuqineni okuphezulu kunye nomphezulu ogudileyo ngelixa kususwa umngcipheko weendawo ezirhabaxa kunye nendawo engenanto, ibonelela ngomphezulu ogqwesileyo ogqibeleleyo kunye nenqanaba eliphezulu lokuchaneka komgangatho.

5.  Iimpawu ezigqwesileyo zoomatshini

Inkqubo yokuphosa ifa ngoko nangoko iqinisa isinyithi solwelo phantsi koxinzelelo oluphezulu, okukhokelela kulwakhiwo lwe-crystallization yengqolowa ecolekileyo enegalelo kumandla empembelelo ephezulu kunye nokuqina.

6.  Umda wobunzima bodonga olusezantsi

I-Die-casting inokuvelisa amacandelo ejometri anzima kunye nobukhulu obuncinci.Nangona kunjalo, ngokungafaniyo nokubunjwa kwesinyithi kunye nokuchithwa kwesanti, ayitshintshi ukuchaneka kwe-dimensional yeendawo ezinobunzima obuncinci.Ukuthetha malunga nomda, i-Aluminium die-casting inomlinganiselo ophantsi wodonga lwe-0.5mm, ngelixa i-zinc alloy ine-0.3mm.

7.  Indlela eyonga iindleko

I-Die casting iya kuba yinkqubo yokuphosa eyonga kakhulu ukuba abavelisi baceba ukuvelisa amacandelo ngobuninzi kuba ukufa okukodwa kunokusetyenziswa kwakhona ngokuphindaphindiweyo kwithuba elide.Kwakhona, ekubeni imathiriyeli ephambili yokusebenza isoloko ikwimo etyhidiweyo, iyanciphisa ukusetyenziswa kwezinto kuba kukho phantse i-100% yezinto zokusebenza eziza kusetyenziswa ukwenza imveliso.

8.  Izinto ezizezinye zinokufakwa.

Kwizinto ezigqityiweyo zokugqibela zeenkqubo ezininzi eziyinkimbinkimbi zomatshini, kukho ukufakwa okanye i-fasteners enzima.I-Die casting yenza abavelisi bakhethe iimpawu ezinjalo kwiimveliso zabo njengoko kufuneka.Ngenxa yoko, igcina ixesha lokuhlanganisa kunye nemali ngokunciphisa iindleko zezinto eziphathekayo.Okokugqibela, Apha Die-casting iphucula ukusebenza kwamalungu kunye nemveliso yonke.

Iingxaki zenkqubo yokufa

Kungakhathaliseki ukuba inkqubo iqhubela phambili kangakanani, zonke iindlela zokuvelisa zinemiqobo kwimisebenzi ethile kunye neemeko.

Ngoku, masiye phezu kwekhon nganye yenkqubo yeDie-casting.

1.  Imveliso yebhetshi encinci ayinakwenzeka ngokwezoqoqosho.

Kwimveliso emincinci, ayilokhetho olunoqoqosho.Njengoko sele kukhankanyiwe, ukwenziwa kwee-dies kubiza kakhulu kwaye kungaphinda kusetyenziswe amawakawaka amaxesha.Ngoko ke, ukuba amacandelo awadingi ukuveliswa ngobuninzi, iindleko zokuvelisa ziya kuba phezulu kakhulu.Isenokungenzeki ngokoqoqosho kwezinye iimeko, njengokuphosa iinxalenye zeenkqubo zamandla omoya.

2.  Umda wobunzima bokuphosa

Inkqubo yokufa inomda wobunzima bokuvelisa amacandelo kunye neemveliso ezigqityiweyo.Nangona kunjalo, umgangatho uwonke wokujulwa kwento enobunzima obungaphantsi kwe-15 yeeponti unokuthotywa ziziphene ezininzi.

3.  Ubomi obuphantsi bokufa kweendawo eziphezulu zokunyibilika

Ezinye ii-alloys, kubandakanywa nezo zenziwe nge-Aluminiyam, ubhedu, kunye neentsimbi ze-ferrous, zinendawo ephezulu yokunyibilika.Ngenxa yoko, ubomi bokufa bufutshane xa kusenziwa ezi ntsimbi, kwaye idiyizi kufuneka ibeneempawu ezikwaziyo ukumelana nobushushu, ezinokubiza kakhulu ukuzifumana.Kwakhona, ukuguqulwa kobushushu kwifa kuya kuchaphazela ukuchaneka komda kunye nezinye iimpawu zezinto zokuphosa.

4.   Iindleko eziphezulu zokuqala

Ngenxa yeendleko eziphezulu zokufa, iyunithi yokulawula, kunye nezinye izixhobo eziyimfuneko, ukukhutshwa kwe-die-cast yinkqubo enzima kakhulu ukuqalisa.Ukongezelela, ukugcinwa kwezixhobo zesiqhelo kuyadingeka ukuze kugcinwe ulawulo lomgangatho kunye nokuchaneka okuchanekileyo.Kuyabiza xa kuthelekiswa nezinye iinkqubo zokuvelisa ezifana nokugalelwa kwesanti, inaliti yeplastiki, umatshini, isinyithi sephepha, njl.

5.  Umngcipheko we-porosity

Ekubeni isinyithi esityhidiweyo, esingenayo i-gas permeability, sitofelwe kwi-cavity ye-die ngesantya esiphezulu sesantya, ukuphosa ukufa kunomngcipheko wokudala umngxuma wegesi kwimveliso ephonswayo.Ke ngoko, amacandelo e-die-cast awafanelekanga kumaqondo obushushu aphezulu okusebenza.
