Amagiyaukuthembela kubukhulu babo besakhiwo namandla wezinto ezibonakalayo ukumelana nemithwalo yangaphandle, okudinga izinto zokwakha zibe namandla aphezulu, ukuqina nokumelana nokugqoka; ngenxa yokuma okuyinkimbinkimbi kwamagiya, iamagiyazidinga ukunemba okuphezulu, nezinto zokwakha nazo zidinga ukwenziwa okuhle. Izinto ezisetshenziswa kakhulu yinsimbi ekhandiwe, insimbi ekhonjiwe, nensimbi yokusansimbi.
1. Insimbi eyakhiwe Ngokuqina kwendawo yezinyo, ihlukaniswe izigaba ezimbili:
Uma i-HB ＜350, ibizwa ngokuthi indawo yezinyo elithambile
Uma i-HB ＞350, ibizwa ngokuthi indawo yezinyo eliqinile
1.1. Ubulukhuni bendawo yezinyo HB＜350
Inqubo: ukubumba kungenalutho → ukujwayela - ukuphenduka okungalungile → ukucisha nokuthulisa, ukuqeda
Izinto ezisetshenziswa kakhulu; 45#, 35SiMn, 40Cr, 40CrNi, 40MnB
Izici: Inokusebenza okuhle kukonke, indawo yezinyo inamandla aphezulu nobulukhuni, kanti umgogodla wezinyo unokuqina okuhle. Ngemuva kokwelashwa kokushisa, ukunemba kweAmagiyaukusika kungafinyelela amabanga ayi-8. Kulula ukuyikhiqiza, iyonga, futhi inokukhiqiza okuphezulu. Ukunemba akuphakeme.
1.2 Ubulukhuni bobuso bezinyo HB ＞350
1.2.1 Uma usebenzisa i-medium carbon steel:
Inqubo: Ukubumba kungenalutho → ukujwayela → ukusika okunzima → ukucisha nokuthambisa → ukusika kahle → ukucisha imvamisa ephezulu naphakathi → ukushisa okuphansi → ukucija noma ukucisha ukungena, inhlansi kagesi ingena ngaphakathi.
Izinto ezisetshenziswa kakhulu:45, 40Cr, 40CrNi
Izici: Ubulukhuni bezinyo buphezulu HRC = 48-55, amandla okuxhumana aphezulu, futhi ukumelana nokugqoka kuhle. Umgogodla wezinyo ugcina ukuqina ngemva kokucisha nokushisa, unokumelana nomthelela omuhle kanye nomthamo ophezulu wokuthwala umthwalo. Ukunemba kuncishiswa ngesigamu, kuze kufike ezingeni lesi-7 lokunemba. Ifanele ukukhiqizwa ngobuningi, njengamagiya okuhambisa anesivinini esimaphakathi kanye naphakathi kwezimoto, amathuluzi omshini, njll.
1.2.2 Uma usebenzisa insimbi enekhabhoni ephansi: Ukubumba kungenalutho → ukujwayela → ukusika okungalungile → ukucisha nokushisa → ukusika kahle → ukungcwatshwa nokucisha → ukushisa okuphansi → ukugaya amazinyo. Kufika kumazinga angu-6 no-7.
Izinto ezisetshenziswa kakhulu; I-20Cr, 20CrMnTi, 20MnB, 20CrMnTo Izici: Ukuqina kwendawo yezinyo namandla okuthwala aqinile. Umnyombo unokuqina okuhle kanye nokumelana nomthelela. Ilungele ukudluliselwa kwesivinini esikhulu, esisindayo, ukugcwala ngokweqile noma izikhathi ezinezidingo zesakhiwo esihlangene, njengegiya eliyinhloko lokudlulisela lezitimela namagiya endiza.
2. Insimbi yokusakaza:
Lapho i-igiyaububanzi d> 400mm, isakhiwo siyinkimbinkimbi, futhi ukukhanga kunzima, insimbi yensimbi eyi-ZG45.ZG55 ingasetshenziselwa ukujwayelekile. Normalization, ukucisha kanye nokushisa.
3. Insimbi:
Ukumelana okuqinile nokunamathela nokugqwala kwemigodi, kodwa ukumelana kabi komthelela nokuhuzuka. Ilungele umsebenzi ozinzile, amandla aphansi, isivinini esiphansi noma usayizi omkhulu kanye nesimo esiyinkimbinkimbi. Ingasebenza ngaphansi kwezimo zokushoda kwamafutha futhi ifanele ukudluliswa okuvulekile.
4. Izinto zensimbi:
Indwangu, ukhuni, ipulasitiki, inayiloni, ifaneleka ngesivinini esikhulu nomthwalo omncane.
Lapho kukhethwa izinto zokwakha, kufanele kucatshangelwe ukuthi izimo zokusebenza zamagiya zihlukile, futhi izinhlobo zokuhluleka kwamazinyo egiya zihlukile, okuyisisekelo sokunquma indlela yokubala yamandla egiya kanye nokukhethwa kwezinto zokwakha nokushisa. amabala.
1. Lapho amazinyo egiya ephuka kalula ngaphansi komthwalo womthelela, izinto zokwakha ezinokuqina okungcono kufanele zikhethwe, futhi insimbi ye-carbon ephansi ingakhethwa ukuze kungcwatshwe futhi kucinywe.
2. Ukuze kudluliselwe isivinini esikhulu esivaliwe, indawo yezinyo ijwayele ukugoba, ngakho-ke izinto ezinobunzima obungcono bezinyo kufanele zikhethwe, futhi ukuqina kwe-carbon steel surface kungasetshenziswa.
3. Ngejubane eliphansi futhi umthwalo ophakathi nendawo, lapho ukuphuka kwezinyo legiya, umgodi, nokuhuzuka kungenzeka, izinto ezinamandla okusebenza kahle, ukuqina kwendawo yezinyo kanye nezinye izici zomshini ezibanzi kufanele kukhethwe, futhi insimbi ye-medium-carbon ecinywe futhi ifuthe kukhethwe.
4. Lwela ukuba nenhlobonhlobo encane yezinto ezisetshenziswayo, okulula ukuyiphatha, futhi ucabangele izinsiza kanye nokuhlinzekwa. 5. Uma usayizi wesakhiwo uhlangene futhi ukumelana nokugqoka kuphezulu, insimbi ye-alloy kufanele isetshenziswe. 6. Amathuluzi nobuchwepheshe beyunithi yokukhiqiza.
