Iindlela zobugcisa ze-aluminium alloy parts processing
1) Ukukhethwa kwedatha yokucubungula
Uluhlu olucwangcisiweyo kufuneka lungqinelane kangangoko kunokwenzeka nedatha yoyilo, idatam yendibano kunye nedatha yomlinganiselo, kunye nozinzo, ukuchaneka kwendawo kunye nokuthembeka kokulungiswa kwamalungu kufuneka kuthathelwe ingqalelo ngokupheleleyo kubugcisa bokucubungula.
2) Umatshini orhabaxa
Ngenxa yokuba ukuchaneka kwe-dimensional kunye noburhabaxa bomphezulu bezinye iindawo ze-aluminium alloy akulula ukuhlangabezana neemfuno ezichanekileyo eziphezulu, ezinye iindawo ezineemo eziyinkimbinkimbi kufuneka zihlanjululwe phambi kokulungiswa, kwaye zidibaniswe neempawu ze-aluminium alloy materials zokusika. Ubushushu obuveliswe ngale ndlela buya kukhokelela kwi-deformation yokusika, amanqanaba ahlukeneyo empazamo kubungakanani bamalungu, kwaye ade akhokelele kwi-deformation ye-workpiece. Ngoko ke, kwinqwelomoya jikelele rough processing processing. Ngelo xesha, ulwelo olupholisayo longezwa ukupholisa i-workpiece ukunciphisa impembelelo yokusika ubushushu ekuchanekeni kwe-machining.
3) Ukugqiba oomatshini
Kumjikelo wokucutshungulwa, ukusika ngesantya esiphezulu kuya kuvelisa ubushushu obuninzi bokusika, nangona i-debris inokuthatha uninzi lobushushu, kodwa isenokuvelisa ubushushu obuphezulu kakhulu kwi-blade, kuba indawo yokunyibilika kwe-aluminium iphantsi, i-blade. idla ngokuba kwi-semi-melting state, ukwenzela ukuba amandla okusika achaphazeleke kubushushu obuphezulu, kulula ukuvelisa iinxalenye ze-aluminium alloy kwinkqubo yokwenza iziphene ze-concave kunye ne-convex. Ngoko ke, kwinkqubo yokugqiba, ngokuqhelekileyo khetha i-fluid yokusika kunye nokusebenza kakuhle kokupholisa, ukusebenza kakuhle kwe-lubrication kunye ne-viscosity ephantsi. Xa izixhobo zokuthambisa, ubushushu bokusika buthathwa ngexesha lokunciphisa ubushushu bomhlaba bezixhobo kunye neenxalenye.
4) Ukukhetha okunengqiqo kwezixhobo zokusika
Xa kuthelekiswa nezinyithi ezityebileyo, amandla okusika awenziwe nge-aluminium alloy ayincinci kwindlela yokusika, kwaye isantya sokusika sinokuba phezulu, kodwa kulula ukwenza amaqhuqhuva e-debris. I-thermal conductivity ye-aluminium alloy iphezulu kakhulu, kuba ukushisa kwenkunkuma kunye neengxenye kwinkqubo yokusika kuphezulu, ukushisa kwendawo yokusika kuphantsi, ukuqina kwesixhobo kuphezulu, kodwa ukunyuka kweqondo lokushisa kwamacandelo ngokwawo. iyakhawuleza, kulula ukubangela deformation. Ke ngoko, kusebenza kakhulu ukunciphisa amandla okusika kunye nokusika ubushushu ngokukhetha isixhobo esifanelekileyo kunye ne-angle yesixhobo esifanelekileyo kunye nokuphucula uburhabaxa besixhobo.
5) Sebenzisa unyango lobushushu kunye nonyango olubandayo ukusombulula deformation processing
Iindlela zokunyanga ukushisa ukuphelisa uxinzelelo lwe-machining yezinto ze-aluminium i-alloy zibandakanya: ukugcinwa kwexesha lokufakelwa, i-recrystallization annealing, njl. Indlela yenkqubo yeengxenye ezinesakhiwo esilula ngokuqhelekileyo samkelwa: umatshini onqabileyo, ukugcinwa kwexesha lezandla, ukugqiba umatshini. Kwindlela yenkqubo yamacandelo anesakhiwo esiyinkimbinkimbi, isetyenziswa ngokubanzi: umatshini onzima, ukulungelelaniswa kwexesha lokwenziwa (unyango lokushisa), ukugqiba ukugqiba, ukugcinwa kwexesha lokwenziwa (unyango lobushushu), ukugqiba umatshini. Ngelixa inkqubo yokwenziwa kwexesha eyenziweyo (unyango lobushushu) icwangciswe emva komatshini orhabaxa kunye nesiqingatha sokugqiba, inkqubo yonyango oluzinzileyo lobushushu inokulungiswa emva kokugqiba umatshini ukuthintela utshintsho oluncinci ngexesha lokubekwa kwamacandelo, ukufakwa kunye nokusetyenziswa.
Iimpawu zenkqubo ye-aluminium alloy parts processing
I-1) Inokunciphisa impembelelo yoxinzelelo oluseleyo kwi-deformation yomatshini.Emva komatshini orhabaxa, kuyacetyiswa ukuba kusetyenziswe unyango lobushushu ukususa uxinzelelo oluveliswa ngoomatshini abarhabaxa, ukuze kuncitshiswe impembelelo yoxinzelelo kumgangatho wokugqiba womatshini.
2) Ukuphucula ukuchaneka komatshini kunye nomgangatho ophezulu.Emva kokwahlulwa kwe-rough and finish machining, ukugqibezela umatshini kunesibonelelo esincinci sokusebenza, uxinzelelo kunye nokuguqulwa, okunokuphucula kakhulu umgangatho wamacandelo.
3) Ukuphucula ukusebenza kakuhle kwemveliso.Ekubeni i-machining rough isusa kuphela izinto ezingaphezulu, ishiya umda owaneleyo wokugqiba, ayicingi ubungakanani kunye nokunyamezela, ngokufanelekileyo ukunika umdlalo ekusebenzeni kweentlobo ezahlukeneyo zezixhobo zoomatshini kunye nokuphucula ukusebenza kakuhle kokusika.
Emva kokuba iinxalenye ze-aluminium alloy zinqunywe, isakhiwo sensimbi siya kutshintshwa kakhulu. Ukongezelela, umphumo wokusika ukunyakaza kubangela uxinzelelo olukhulu oluseleyo. Ukuze kuncitshiswe i-deformation yamacandelo, uxinzelelo olushiyekileyo lwezinto kufuneka lukhululwe ngokupheleleyo.
