Iigiyazixhomekeke kubukhulu bazo bolwakhiwo kunye namandla ezinto ukuze zikwazi ukumelana nemithwalo yangaphandle, nto leyo efuna ukuba izinto zibe namandla aphezulu, ziqine kwaye zingagugi; ngenxa yesimo esintsonkothileyo seegiya,izixhobozifuna ukuchaneka okuphezulu, kwaye izixhobo nazo zifuna ukwenziwa kakuhle. Izinto ezisetyenziswa rhoqo yintsimbi eqingqiweyo, intsimbi eqingqiweyo, kunye nentsimbi eqingqiweyo.
1. Intsimbi eqiniweyo Ngokwendlela obulukhuni ngayo umphezulu wezinyo, yahlulwe yangamacandelo amabini:
Xa i-HB <350, ibizwa ngokuba ngumphezulu wamazinyo athambileyo
Xa i-HB ＞350, ibizwa ngokuba ngumphezulu wamazinyo aqinileyo
1.1. Ubulukhuni bomphezulu wezinyo HB <350
Inkqubo: ukubumba okungenanto → ukulungisa - ukuguqula gwenxa → ukucima nokulungisa, ukugqiba
Izixhobo ezisetyenziswa rhoqo; 45#, 35SiMn, 40Cr, 40CrNi, 40MnB
Iimpawu: Isebenza kakuhle iyonke, umphezulu wezinyo unamandla aphezulu kwaye ulukhuni, kwaye umongo wezinyo uqinile kakuhle. Emva konyango lobushushu, ukuchanekaIigiyaUkusikwa kwayo kungafikelela kwiigreyidi ezisi-8. Kulula ukuyenza, ingabizi kakhulu, kwaye inemveliso ephezulu. Ukuchaneka kwayo akuphezulu.
1.2 Ubulukhuni bomphezulu wamazinyo HB ＞350
1.2.1 Xa usebenzisa intsimbi yekhabhoni ephakathi:
Inkqubo: Ukwakha ingenanto → ukulungelelanisa → ukusika okurhabaxa → ukucima kunye nokulungisa → ukusika okucolekileyo → ukucima i-frequency ephezulu nephakathi → ukufudumala okuphantsi kobushushu → ukukhanyisa okanye ukuqalisa ukusebenza, i-spark yombane isebenza.
Izixhobo ezisetyenziswa rhoqo:45, 40Cr, 40CrNi
Iimpawu: Ubunzima bomphezulu wezinyo buphezulu HRC=48-55, amandla okudibana aphezulu, kwaye ukumelana nokuguguleka kulungile. Umbindi wezinyo ugcina ukuqina emva kokucinywa nokuthomalaliswa, unokumelana okuhle kwempembelelo kunye nomthamo ophezulu wokuthwala umthwalo. Ukuchaneka kuncitshiswa ngesiqingatha, ukuya kwinqanaba lesi-7 ukuchaneka. Ifanelekile kwimveliso yobuninzi, njengeegiya zokuhambisa umthwalo ophakathi kunye nomthwalo ophakathi kwiimoto, izixhobo zoomatshini, njl.njl.
1.2.2 Xa usebenzisa intsimbi ekhabhoni ephantsi: Ukubumba ingenanto → ukulungelelanisa → ukusika okurhabaxa → ukucima nokulungisa → ukusika okucolekileyo → ukugaya nokucima → ukufudumala okuphantsi kobushushu → ukugaya amazinyo. Ukuya kuthi ga kumanqanaba ama-6 kunye nama-7.
Izixhobo ezisetyenziswa rhoqo; 20Cr, 20CrMnTi, 20MnB, 20CrMnTo Iimpawu: Ubulukhuni bomphezulu wamazinyo kunye nomthamo oqinileyo wokuthwala. Umbindi unobulukhuni obuhle kunye nokumelana nempembelelo. Ifanelekile kwi-transmission yesantya esiphezulu, imithwalo enzima, i-overload okanye kwiimeko ezineemfuno zesakhiwo esincinci, njengegiya yokudlulisa ephambili yee-locomotives kunye neegiya zeenqwelomoya.
2. Intsimbi eyenziwe ngesinyithi:
XaizixhoboUbubanzi bayo bungaphezulu kwe-400mm, isakhiwo siyinkimbinkimbi, kwaye ukufakelwa kwayo kunzima, izinto zentsimbi ezibunjiweyo i-ZG45.ZG55 zingasetyenziselwa ukulungelelanisa. Ukulungisa, ukucima kunye nokulungisa.
3. Isinyithi esenziwe ngentsimbi:
Ukumelana okunamandla nokunamathela kunye nokugqwala kwemingxuma, kodwa ukumelana okuncinci kwimpembelelo kunye nokukrala. Ifanelekile ukusebenza okuzinzileyo, amandla aphantsi, isantya esiphantsi okanye ubungakanani obukhulu kunye nemilo enzima. Ingasebenza phantsi kweemeko zokunqongophala kweoyile kwaye ifanelekile ukuhanjiswa okuvulekileyo.
4. Izinto zesinyithi:
Ilaphu, umthi, iplastiki, i-nylon, ifanelekile kwisantya esiphezulu kunye nomthwalo olula.
Xa kukhethwa izinto, kufuneka kuqwalaselwe into yokuba iimeko zokusebenza zeegiya zahlukile, kwaye iintlobo zokusilela kwamazinyo egiya zahlukile, ezisisiseko sokumisela iikhrayitheriya zokubala amandla egiya kunye nokukhethwa kwezinto kunye neendawo ezishushu.
1. Xa amazinyo egiya ephuka lula xa ethe wawa phantsi komthwalo, kufuneka kukhethwe izixhobo ezinobunzima obungcono, kwaye kukhethwe intsimbi enekhabhoni ephantsi ukuze kufakwe i-carburizing kunye ne-quenching.
2. Kwi-transmission evaliweyo ngesantya esiphezulu, umphezulu wezinyo unokuba neengxobo, ngoko ke kufuneka kukhethwe izixhobo ezinobunzima obungcono bomphezulu wezinyo, kwaye kungasetyenziswa ukuqina komphezulu wentsimbi yekhabhoni ephakathi.
3. Kwisantya esiphantsi kunye nomthwalo ophakathi, xa izinyo legiya liqhekeka, liqhekeka, kwaye linokukrazulwa, kufuneka kukhethwe izixhobo ezinamandla oomatshini, ubulukhuni bomphezulu wezinyo kunye nezinye iimpawu zoomatshini ezipheleleyo, kwaye kukhethwe intsimbi yekhabhoni ephakathi ecinyiweyo neqinisiweyo.
4. Zama ukuba neentlobo ngeentlobo zezinto zokwakha, ezilula ukuzilawula, kwaye ucinge ngezixhobo kunye nobonelelo.
5. Xa ubungakanani besakhiwo buncinci kwaye ukumelana nokuguguleka kuphezulu, kufuneka kusetyenziswe intsimbi ye-alloy.
6. Izixhobo kunye netekhnoloji yeyunithi yokuvelisa.
