Iziko lokubumba elifudumeleyo

Isithando somlilo esifudumeleyo sisithando somlilo esingaqhelekanga esisetyenziswa rhoqo kwishishini lokubumba. Intsimbi ejikelezileyo ifudumala ngokufudumeza kwangaphambili kunye nokutshiza igraphite kwaye emva koko ishushu kwiqondo lokushisa elifunekayo ukuze kufakwe ukufudumala, okuyindlela yokufudumeza yesibini. Iseti yonke yezixhobo ixhotyiswe ngokutya kwebhodi yokuhlamba ngokuzenzekelayo, ukuhanjiswa kwekhonkco, umatshini wokutshiza wegraphite ngokuzenzekelayo kunye nezinye izixhobo zokuqonda i-automation epheleleyo kunye nobukrelekrele beziko elifudumeleyo lokubumba.

1. Ingqikelelo eshushu yokubumba iziko elifudumeleyo lokubumba:

Xa intsimbi engqukuva ifudunyezwa, iqondo lobushushu lentsimbi engqukuva limalunga ne-750 °C. Xa ukubunjwa kwenziwa kwiqondo lokushisa elingaphezulu kwe-700 ° C, amandla okuguqula anokuthi akhululwe ngokuguquguqukayo, kwaye ukuchasana kokwenza kuncitshiswe ngokukhawuleza; xa uqulunqa kwi-700-850 ° C, i-forging i-oxidized. Kukho izikhumba ezincinci, i-decarburization yomphezulu incinci, kwaye ubungakanani be-forging butshintsha kancinci; xa kusenziwa ngaphezulu kwe-950 °C, nangona amandla okwenza incinci, isikali kunye ne-surface decarburization ye-forging inzulu, kwaye ubungakanani bokubumba buguquka kakhulu. Ke ngoko, ukubumba kuluhlu lwe-700-850 ° C kunokufumana i-forgings ngomgangatho ongcono kunye nokuchaneka.

Ukufudumala okufudumeleyo kwesithando somlilo sokufudumala kubhekiselele ekwenziweni kweentsimbi zentsimbi eziya kuba ngaphantsi kobushushu becrystallization kwaye buphakame kunobushushu obuqhelekileyo. Injongo yokusebenzisa inkqubo yokufudumala efudumeleyo kukufumana i-forgings echanekileyo, kunye nenjongo yokufudumala okufudumeleyo kukuphucula ukuchaneka kunye nomgangatho we-forging ngaphandle kwamandla amakhulu okwenza ukubanda okubandayo.

2, ukufudumeza iziko elifudumeleyo lokubumba:

Isithando somlilo esifudumeleyo luhlobo lokufudumeza okufakwe kwi-intanethi kusetyenziswa iiseti ezimbini zeenkqubo zokufudumeza iziko eliphakathi, iseti enye yesithando somlilo esiphakathi sifudunyezwa kwi-intanethi, enye iseti yesithando somlilo esiphakathi sifudunyezwa ekugqibeleni, kwaye intsimbi yokusebenza engqukuva ichanekile. shushu. Kukho ibhokisi yejethi ye-inki ezenzekelayo phakathi kweeseti zeziko lokufudumeza. Itanki yokutshiza yegraphite ibekwe phakathi kwesithando sokufudumala esiphakathi kwamaxesha okufudumeza kunye nesithando somlilo sokufudumeza. I-billet preheated ifafazwe ngegraphite kwi-intanethi, kwaye i-billet efafaziweyo ishushu kwi-furnace induction induction. Ukutshiza kwegraphite kunokupholisa i-billet kwindawo ebandayo kwaye kuthintele i-decarburization. Ngexesha lenkqubo ye-extrusion, i-graphite nayo idlala indima yokuthambisa kunye nokukhusela i-mold.

Ubushushu obufudumezayo beziko lokufudumeza olufudumalayo lukholisa ukuba yi-120°C ukuya kwi-150°C. Emva kokuba ukufudumala kugqityiwe, i-workpiece kufuneka ifafazwe ngegraphite. Ngokukodwa, uyilo lomzila wesikhokelo kunye noyilo lwe-nozzle lunendlela yalo ekhethekileyo.

3. Ukwakhiwa kwesithando somlilo esifudumeleyo:

Iziko elifudumeleyo lokubumba liqulathe unikezelo lwamandla amabini azimeleyo aphakathi, iiseti ezimbini zembuyekezo yamatyeli aphakathi aphakathi, isixhobo sokuguqula isakhelo semathiriyeli, ibhodi yokuhlambela ezenzekelayo (enyathelweyo) indlela yokutya, indlela yokuhambisa eqhubekayo, indlela yokutyisa echaswe ngokuthe tye, kunye nesandulela. -itanki yokutshiza. Iqulunqwe sisikhululo sempompo, ulawulo lombane kunye nenkqubo yokusebenza, inkqubo yokulinganisa ubushushu kunye nenkqubo yokuhlela.
