Iigiyabathembele kwimilinganiselo yabo yesakhiwo kunye namandla ezinto eziphathekayo ukuze baxhathise imithwalo yangaphandle, efuna ukuba izinto zibe namandla aphezulu, ukuqina kunye nokuxhatshazwa kokugqoka; ngenxa yobume obuntsonkothileyo beegiya, iizixhobozifuna ukuchaneka okuphezulu, kwaye imathiriyeli ifuna ukwenziwa kakuhle. Izinto ezisetyenziswa ngokuqhelekileyo yintsimbi ekhandiweyo, intsimbi etyhidiweyo, kunye nentsimbi.
1. Intsimbi ekhutshiweyo Ngokobunzima bomhlaba wezinyo, yahlulwe yangamacandelo amabini:
Xa i-HB ＜350, ibizwa ngokuba yindawo yezinyo elithambileyo
Xa i-HB ＞350, ibizwa ngokuba yindawo yezinyo eliqinileyo
1.1. Ukuqina komphezulu wezinyo HB＜350
Inkqubo: ukubumba into engenanto → ukuqhelanisa - ukujika ngokurhabaxa → ukucima nokuthambisa, ukugqiba
Izinto ezisetyenziswa ngokuqhelekileyo; 45#, 35SiMn, 40Cr, 40CrNi, 40MnB
Iimpawu: Inokusebenza kakuhle ngokubanzi, umphezulu wezinyo unamandla aphezulu kunye nokuqina, kwaye umbindi wezinyo unokuqina okuhle. Emva kokunyanga ubushushu, ukuchaneka kweIigiyaukusika kunokufikelela kumabanga asi-8. Kulula ukuyenza, inoqoqosho, kwaye inemveliso ephezulu. Ukuchaneka akukho phezulu.
1.2 Ukuqina komphezulu wamazinyo HB ＞350
1.2.1 Xa usebenzisa intsimbi yekhabhoni ephakathi:
Inkqubo: Ukubumba into engenanto → ukuqhelanisa → ukusika okurhabaxa → ukucima nokuthambisa → ukusika kakuhle → ukucinywa kwamatyeli aphezulu naphakathi → ubushushu obuphantsi → ukuhombisa okanye ukugrumba ukubaleka ngaphakathi, intlantsi yombane ingena ngaphakathi.
Izinto ezisetyenziswa ngokuqhelekileyo:45, 40Cr, 40CrNi
Iimpawu: Ubunzima bobuso bezinyo buphezulu HRC = 48-55, amandla oqhagamshelwano aphezulu, kwaye ukuxhathisa ukunxiba kulungile. I-core yezinyo igcina ukuqina emva kokucima kunye nokufudumala, inokumelana nempembelelo efanelekileyo kunye nomthamo ophezulu wokuthwala umthwalo. Ukuchaneka kuncitshiswe ngesiqingatha, ukuya kwinqanaba le-7 ukuchaneka. Ilungele imveliso yobuninzi, efana nesantya esiphakathi kunye neegiya zokuhambisa umthwalo ophakathi kwiimoto, izixhobo zoomatshini, njl.
1.2.2 Xa usebenzisa intsimbi yekhabhoni ephantsi: Ukubumba into engenanto → ukwenziwa kwesiqhelo → ukusika ngokurhabaxa → ukucima nokufutha → ukusika kakuhle → ukungcwatywa nokucima → ubushushu obuphantsi → ukucola amazinyo. Ukuya kwi-6 kunye ne-7 amanqanaba.
Izinto ezisetyenziswa ngokuqhelekileyo; I-20Cr, i-20CrMnTi, i-20MnB, i-20CrMnTo Iimpawu: Ubunzima bomhlaba wezinyo kunye nomthamo oqinileyo wokuthwala. Undoqo unokuqina okulungileyo kunye nokumelana nempembelelo. Ilungele isantya esiphezulu, umthwalo onzima, ugqithiso olugqithisiweyo okanye amaxesha aneemfuno zesakhiwo esibambeneyo, njengesona sixhobo siphambili sothumelo lweenqwelo-moya kunye nezixhobo zokubhabha.
2. Intsimbi yokuphosa:
Xa iizixhoboI-diameter d> 400mm, isakhiwo sinzima, kwaye ukukhwabanisa kunzima, i-cast steel material ZG45.ZG55 ingasetyenziselwa ukuqhelekileyo. Ukuqheleka, ukucima kunye nokuthoba.
3. Intsimbi:
Ukuchasana okunamandla kwi-adhesion kunye ne-corrosion ye-pitting, kodwa ukuxhathisa okungahambi kakuhle kwimpembelelo kunye nokukrazula. Ilungele umsebenzi ozinzile, amandla aphantsi, isantya esiphantsi okanye ubukhulu obukhulu kunye nesimo esinzima. Inokusebenza phantsi kweemeko zokunqongophala kweoli kwaye ifanelekile ukuhanjiswa okuvulekileyo.
4. Imathiriyeli yesinyithi:
Ilaphu, ukhuni, iplastiki, inayiloni, ifanelekile kwisantya esiphezulu kunye nomthwalo olula.
Xa ukhetha izinto eziphathekayo, kufuneka kuthathelwe ingqalelo into yokuba iimeko zokusebenza kweegiya zahlukile, kwaye iindlela zokungaphumeleli kwamazinyo egiya zahlukile, ezisisiseko sokumisela indlela yokubala amandla esixhobo kunye nokukhethwa kwezixhobo kunye nokutshisa. amabala.
1. Xa amazinyo e-gear ephulwa lula phantsi komthwalo wempembelelo, izinto ezinobunzima obungcono kufuneka zikhethwe, kwaye i-carbon steel ephantsi ingakhethwa kwi-carburizing kunye nokucima.
2. Ukuhanjiswa kwesantya esiphezulu esivaliweyo, indawo yezinyo ixhomekeke kwi-pitting, ngoko ke izinto ezinobunzima obungcono bezinyo kufuneka zikhethwe, kunye ne-medium carbon steel surface lukhuni ingasetyenziswa.
3. Kwisantya esisezantsi kunye nomthwalo ophakathi, xa ukuphuka kwezinyo legiya, ukugoba, kunye nokuqhawuka kunokwenzeka, izixhobo ezinamandla okusebenza kakuhle, ukuqina komphezulu wezinyo kunye nezinye iipropathi ezibanzi zoomatshini kufuneka zikhethwe, kunye nentsimbi ephakathi kwekhabhoni ecinywe kwaye inomsindo. khethwa.
4. Zama ukuba neentlobo ngeentlobo zemathiriyeli, kulula ukuzilawula, kwaye uqwalasele izibonelelo kunye nokubonelela. 5. Xa ubungakanani besakhiwo bubumbene kwaye ukuxhathisa ukunxiba kuphezulu, kufuneka kusetyenziswe insimbi ye-alloy. 6. Izixhobo kunye nobuchwepheshe beyunithi yokuvelisa.
