Izinto zokubumba i-Carbide zidinga ukuhlangabezana nezidingo zokusebenza

I-carbide efakwe usimendeizinto zokwakha zidinga ukuba nezakhiwo ezine ezinkulu:
1. ngokuqina okuphezulu:i-tungsten carbide iyafaenqubweni ye-extrusion ukuze ngesikhathi esifanayo imelane nokucindezela okukhulu kwe-extrusion, ukucindezeleka okugoba, umthelela kanye neminye imithwalo eyinkimbinkimbi.Ngakho-ke, izidingo zezinto ezikhethiwe, emva kokwelashwa okushisa, kufanele zibe nokuqina okuphezulu.Ngakho-ke, izinto zokufa kufanele zibe nokuqina okuhle, ukuze kuqinisekiswe ukuthi ukufa kungenziwa lukhuni futhi kuhlelwe ngendlela efanayo.I-carbide enkulu kanye ne-deflection engathi sína, i-fiber directional ne-non-metallic inclusions kanye nezinye iziphambeko zangaphakathi, kuzokwenza ukuqina kwesikhunta kuncishiswe, noma emthwalweni obangelwa ukugxila kokucindezeleka, okuholela ekulimaleni kokuqala kwesikhunta.

2. Ukumelana nokugqoka okuhle: ukufa kufanele kube nokumelana nokugqoka okuphezulu, ukuze kuqinisekiswe impilo evamile yenkonzo, ukukhiqizwa kwenani elikhulu lama-extrusions afanelekayo.Ngokuvamile, ubulukhuni bensimbi nokumelana nokugqoka ngaphansi kwezimo ezithile kuyalingana.Ngakho-ke, izinto zokufa akufanele zibe nokuqina okwanele kuphela, kodwa futhi zibe nokuqina okuphezulu.Kodwa ngaphezu kokuqina, nquma ukumelana nokugqokwa kwensimbi nokwelashwa kokushisa kwenhlangano ye-matrix ye-coarse, ukwakheka, okweqile nomlomo womlilo we-carbide isigaba esingakanani, ubukhulu, uhlobo, ukuhlakazeka nobulukhuni obomvu, njll. -Speed ​​steel kanye low-alloy ithuluzi insimbi, nakuba ubulukhuni efanayo value ngemva kokwelashwa ukushisa, ukusetshenziswa langempela, wangaphambili bafake ukumelana kuphakeme kakhulu, futhi iqukethe ezingaphezu kuka-80% ofI-WC carbide, ukumelana kwayo nokugqoka kunensimbi izikhathi eziphindwe kashumi.Ngakho-ke, ekukhiqizeni okukhulu kwe-extrusion, ukuze uthole impilo ende yesevisi ye-die, intengo ephakeme kakhulu, inqubo eyinkimbinkimbi yensimbi enesivinini esikhulu, i-carbide yezinto ezifayo.

3. Ukuzinza okwanele okushisayo: Lapho ukukhiqizwa okuqhubekayo, ukunyuka kwezinga lokushisa kwesikhunta ngezinye izikhathi kufinyelela noma kudlula i-200 ℃, okuyi-160 ~ 180 ℃ yezinto zokushisa ukushisa kwesikhunta, kuzokwenza amandla, ubulukhuni behle, ngakho-ke izinga lokushisa likhuphuka ngenxa yesikhunta esiphezulu. izinto zokwakha, kufanele zibe nokuzinza okuhle kokushisa.

4. ubuchwepheshe obuhle: umjikelezo wokukhiqiza we-extrusion die mude, inqubo eyinkimbinkimbi, izidingo zokunemba okuphezulu.Ngokuvamile zingaphansi kokukhandwa, ukusika, ukwelashwa ngokushisa, ukugaya noma ezinye izinqubo zokuqeda.Ngakho-ke, inqubo kuphela impahla kuqhathaniswa okuhle, ukuhlangabezana nezidingo zokukhiqiza.
