Ibha yensimbi eyindilinga yigama elijwayelekile lensimbi elingasetshenziswa ukucubungula nokwenza amagiya.Ngokuvamile, kukhona izinsimbi ezinekhabhoni ephansi njengensimbi engu-20#, izinsimbi ezine-carbon alloy ephansi ezifana no-20Cr kanye no-20CrMnTi, izinsimbi ezinekhabhoni ephakathi njengensimbi engu-35# kanye nensimbi engu-45#, nezinsimbi ezine-carbon alloy ezimaphakathi ezifana no-40Cr, 42CrMo. kanye ne-35CrMo, konke okungabizwa ngokuthi izinsimbi zegiya.
Lolu hlobo lwensimbi luvamise ukuba namandla amahle, ukuqina kanye nokuqina ngemva kokwelashwa kokushisa ngokwezidingo zokusetshenziswa, noma indawo engaphezulu ayigugi futhi isikhungo sinokuqina okuhle kanye nokumelana nomthelela.
Imininingwane
1).Material: 45#, 16MnCr5, 35SiMn, 40Cr, 40CrNi, 40MnB, 42CrMo, 35CrMo, ngokwesidingo sekhasimende
2).Ukupakisha: ukupakisha okujwayelekile okufanele ulwandle
3).Ukwelashwa okungaphezulu: kubhontshiwe, kushiselwe, kupendwe noma ngokwesidingo sekhasimende
4).Usayizi: ngokuvumelana nemfuneko yekhasimende
Ukuthuthukiswa kweGear Steel
I-Gear steel ingenye yezinto ezibalulekile ezinezidingo eziphakeme zensimbi ye-alloy ekhethekile esetshenziswa ezimotweni, ezitimeleni, emikhunjini nasemishinini yokwakha, futhi iyimpahla yokukhiqiza yezingxenye eziyinhloko ukuqinisekisa ukuphepha.Eminyakeni yamuva nje, insimbi yegiya iyathuthuka ibheke ekusebenzeni okuphezulu, impilo yesevisi ende, ukusebenza kwegiya okuzinzile, umsindo ophansi, ukuphepha, izindleko eziphansi, ukucubungula kalula nezinhlobonhlobo ezihlukahlukene.
Ukuhlukaniswa Kwezinto Zensimbi Yegiya
Izinto ezisetshenziswa kakhulu zegiya lensimbi yinsimbi engumgunyathi kanye nensimbi ecijile.Phakathi kwazo, insimbi ekhonjiwe ngokuvamile isetshenziswa ekwenzeni amagiya anobubanzi obungaphezu kuka-400mm kanye nesakhiwo esiyinkimbinkimbi esingafanele ukufoja.Kwezinye izimo, insimbi ehlanganisiwe ifaneleka kakhulu.Insimbi eyenziwe ngomgunyathi esetshenziswa Ngokusho kokuqina kwezinyo ebusweni nakho kuhlukile:
1).Indawo yezinyo elithambile
Ubulukhuni bezinyo obungaphansi kuka-350mm bubizwa ngokuthi indawo yezinyo elithambile, insimbi yegiya evame ukusetshenziswa endaweni yezinyo elithambile iyi-45# steel, 35SiMn, 40Cr, 40CrNi, 40MnB.
2).Amazinyo aqinile
Ubulukhuni bezinyo obungaphezulu kuka-350mm bubizwa ngokuthi indawo yezinyo eliqinile.Insimbi yegiya esetshenziselwa indawo yezinyo eliqinile ingahlukaniswa ibe yinsimbi ye-carbon ephakathi nensimbi ephansi ye-carbon.Medium carbon steel kuhlanganisa 35 # steel, 45 # steel,
I-40Cr, 40CrNi, 42CrMo, 35CrMo, njll. Insimbi ye-carbon ephansi ihlanganisa i-20Cr, 20CrMnTi, 20MnB, 20CrMnTo, njll.
Isicelo
1) I-42CrMo yensimbi yegiya inezici zamandla aphezulu, amandla aphezulu okuqina, ukuqina okuhle, ukuguquguquka okuncane ngesikhathi sokucisha, amandla aphezulu okukhasa kanye namandla ahlala isikhathi eside ekushiseni okuphezulu.
Isetshenziselwa ukwenza ama-forging adinga amandla aphezulu kanye nezingxenye ezinkulu ezicishiwe neziqinile kunensimbi engu-35CrMo, njengalezi: amagiya amakhulu okudonsa kwesitimela, amagiya okuhambisa i-supercharger, amagiya omkhumbi ocindezelayo, ama-ekseli angemuva, izinduku zokuxhuma ezilayishwe ngokwedlulele neziphethu Ingasetshenziselwa futhi amapayipi okubhoboza amanzi ajulile kawoyela kanye namathuluzi okudoba ngaphansi kwama-2000m;futhi ingasetshenziselwa isikhunta semishini yokugoba, njll.
2) Insimbi yegiya engu-20CrMnTiH iyinsimbi egoqayo esebenza kahle, ikhono eliphezulu lokuqina, indawo eqinile futhi engagugi futhi iqinile ngemuva kokungcwatshwa nokucisha, ukuqina komthelela ophansi wokushisa okuphansi, amandla okushisela, futhi ingashiselwa ngemuva kokujwayelekile Okuhle. ukusebenziseka kalula.
Isetshenziselwa ukwenza izingxenye ezibalulekile ezine-cross-section<30mm ezimelana nesivinini esikhulu, esiphakathi noma esindayo, umthelela kanye nokungqubuzana;okufana nalokhu: amagiya, amagiya amagiya, ama-cross-head shaft egiya, njll. Kuyinsimbi ethatha indawo ye-18CrMnTi, esetshenziswa kabanzi njengezingxenye ze-carburized.Isetshenziswa ezimbonini zezimoto nezagandaganda ezinengxenye engaphansi kuka-30mm;iyingxenye ebalulekile ye-carburized ethwala imithwalo yesivinini esikhulu, ephakathi noma esindayo futhi engaphansi komthelela nokungqubuzana;
