Izizathu eziqhekezayo zokufa kweringi zintsonkothile kwaye kufuneka zihlalutywe ngokweenkcukacha.Kodwa inokushwankathelwa ikakhulu njengezi zizathu zilandelayo.
1. Izinto ezisetyenziswe kwi-ring ring sesinye sezizathu ezibalulekileyo.Okwangoku, i-4Cr13 kunye ne-20CrMnTid zisetyenziswa kakhulu kwilizwe lethu, elizinzileyo.Kodwa umenzi wezinto eziphathekayo wahlukile, kwizinto ezifanayo, izinto zokulandelela ziya kuba nomsantsa othile, ziya kuchaphazela umgangatho wokubumba umsesane.
2. Inkqubo yokuqulunqa.Eli likhonkco elibalulekileyo kwinkqubo yokwenziwa komngundo.Kwi-alloy high metal mold, iimfuno zokusasazwa kwe-carbide kunye nolunye uhlobo lwe-metallographic luhlala lubekwe phambili.Kukwayimfuneko ukulawula ngokungqongqo uluhlu lweqondo lobushushu lokubumba, ukwenza iinkcukacha ezichanekileyo zokufudumeza, ukwamkela indlela echanekileyo yokubumba, kunye nokupholisa okucothayo okanye ukufakwa ngexesha elifanelekileyo emva kokufota.Inkqubo non-standard kulula ukukhokelela ukuqhekeka umzimba ring die.
3. Lungiselela unyango lobushushu.Ngokutsho izixhobo ezahlukeneyo kunye neemfuno die, annealing, tempering kunye nezinye iinkqubo zokulungiselela unyango ubushushu ngokulandelelana zisetyenziselwa ukuphucula isakhiwo, ukuphelisa ubuphene isakhiwo forging kunye blank, ngoko ukuphucula ukusebenza.Emva kokulungiswa okufanelekileyo kokulungiswa kokushisa kwensimbi ephezulu ye-carbon alloy die, i-carbide yenethiwekhi inokupheliswa, enokwenza i-carbide i-spheroidized kwaye ihlanjululwe, kwaye ukuhanjiswa okufanayo kwe-carbide kunokukhuthazwa.Oku kulungele ukuqinisekisa ukucima, umgangatho wokufudumala, ukuphucula ubomi benkonzo yokubumba.
Pellet yokusila kufa unyango ubushushu
1. Ukucima kunye nokufudumala.Eli likhonkco eliphambili kunyango lobushushu bokufa.Ukuba ukufudumala kwenzeka ngexesha lokucima ukufudumeza, akuyi kubangela kuphela i-brittleness enkulu ye-workpiece, kodwa kulula ukwenza i-deformation kunye nokuqhekeka ngexesha lokupholisa, okuya kuchaphazela kakhulu ubomi benkonzo yokubumba.Inkcazo yenkqubo yonyango lokushisa kufuneka ilawulwe ngokungqongqo kwaye unyango lwe-vacuum lokushisa kufuneka lwamkelwe.Ukushisa kufuneka kwenziwe ngexesha emva kokucima, kwaye ngokweemfuno zobugcisa ukwamkela inkqubo yokushisa eyahlukileyo.
2. I-stress-relieving annealing.I-die kufuneka ifakwe kwi-stress-relieving annealing treatment emva kokucoca ngokucokisekileyo, ukwenzela ukuphelisa uxinzelelo lwangaphakathi olubangelwa ukucwangciswa kwe-machining, ukwenzela ukuba ugweme ukuguqulwa okukhulu okanye ukuqhekeka okubangelwa ukucima.Ukufa okunemfuno echanekileyo ephezulu, kufuneka kwakhona kunyango lokunciphisa uxinzelelo emva kokusila, okuluncedo ukuzinzisa ukuchaneka kokufa kunye nokuphucula ubomi benkonzo.
Ukuvula umngxuma izinga lokufa ring
Ukuba izinga lokuvula umngxuma wokufa kweringi liphezulu kakhulu, ithuba lokuqhekeka kweringi liya kwanda.Ngenxa yomgangatho ohlukeneyo wonyango lobushushu kunye nenkqubo, kuya kubakho umahluko omkhulu phakathi komenzi ngamnye wokufa kweringi.Ngokuqhelekileyo, i-pellet yethu yokusila inokuphucula izinga lokuvula umngxuma nge-2-6% kwisiseko se-mold ye-brand brand yasekhaya, kwaye inokuqinisekisa ubomi benkonzo ye-ring mold.
I-Pellet mill iyanxiba
ubukhulu obuthile kunye namandla ancitshiswe kwinqanaba lokuba alikwazi ukuthwala uxinzelelo lwe-granulation, ukuqhekeka kuya kwenzeka.Kucetyiswa ukuba xa kufa kweringi kunxitywe kwinqanaba le-roller shell groove, umsesane wokufa kufuneka utshintshwe ngexesha.
Xa ilitye lokusila lisifa kwinkqubo yegranulation, ubungakanani bezinto kwi-pellet mill die ayinakusebenza kwi-100%.Nangona isivuno seringi sokufa segranulation siphezulu, kodwa ixesha elide elinjalo lokusebenza kwamandla aphezulu, liya kuphinda lisebenze. kukhokelela ekuqhekekeni komsesane kufa.Sincoma ukulawula kwi-75-85% yomthwalo ukuqinisekisa ubomi benkonzo ye-ring die.
Ukuba iringi iyafa kwaye i-press roll icinezelwe kakhulu, kulula ukuyiqhekeza.Ngokuqhelekileyo, sifuna ukuba umgama phakathi kwe-ring ring kunye ne-press roll ulawulwe phakathi kwe-0.1-0.4mm.
ezahlukeneyo
Kulula ukuqhekeka xa izinto ezinzima ezifana nentsimbi zivela kwi-pelleting material.
Ufakelo lweringi yokufa kunye nomatshini wokubetha
Ufakelo lokufa kweringi aluqinanga, kuya kubakho umsantsa phakathi komsesane wokufa kunye nomatshini wokubetha, kunye nokuqhekeka kweringi kuya kwenzeka kwinkqubo yokugaya.
Emva konyango lobushushu, umsesane wokufa uya konakala kakhulu.Ukuba ayilungiswanga, ukufa kweringi kuya kuqhekezwa ngokusetyenziswa.
Xa umatshini we-pelleting ngokwawo uneziphene, ezifana ne-shaft ephambili yomatshini wokugaya ukugubha.
