Ukukhethwa kwendlela yokucima ulwelo lwentsimbi oluyi-45#: ukusebenza, ukusetyenziswa kunye nokuthelekisa
Kwicandelo lokwenziwa koomatshini, i-roller chain yinxalenye ephambili yokudlulisa, kwaye ukusebenza kwayo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokuthembeka kwezixhobo zoomatshini. I-45# steel roller chain isetyenziswa kakhulu ngenxa yexabiso layo eliphantsi kunye neempawu zayo eziphakathi zoomatshini, kwaye inkqubo yokucima ibalulekile ekuphuculeni ubulukhuni bayo, amandla kunye nokumelana nokuguguleka. Ukukhetha i-quenching medium kumisela umgangatho wesiphumo sokucima. Eli nqaku liza kuhlola nzulu i-quenching medium efanelekileyo kwi-45# steel roller chain ukunceda abathengi bamazwe ngamazwe kunye nabavelisi abathengisa ngobuninzi baphucule ukusebenza kwemveliso kunye nokwandisa ixabiso lorhwebo.
1. Iimpawu kunye neemfuno zokucima ze-45# steel roller chain
Intsimbi ye-45# yintsimbi ephakathi yekhabhoni eneempawu ezintle zoomatshini, ezinje ngamandla aphezulu, ubulukhuni kunye nokuqina, kunye netekhnoloji elungileyo yokucubungula, eyenza ukuba ibe yinto efanelekileyo yokwenza imixokelelwane yeroller. Nangona kunjalo, ukuqina kwayo kuphantsi kakhulu, ingakumbi kwiindawo ezinkulu, kwaye kunzima ukufumana isakhiwo esifanayo se-martensitic ngexesha lokucima. Ke ngoko, ukuze kuhlangatyezwane neemfuno zemixokelelwane yeroller ngokubhekiselele kumandla aphezulu, ukumelana nokuguguleka kunye nobomi bokudinwa, kuyimfuneko ukukhetha i-medium yokucima efanelekileyo ukuze kufezekiswe ukupholisa ngokukhawuleza nangokulinganayo kunye nokuphucula ubunzulu bomaleko oqinileyo kunye nokusebenza ngokubanzi kwamalungu.
2. Izixhobo zokucima eziqhelekileyo kunye neempawu zazo
(I) Amanzi
Amanzi yeyona ndlela yokucima amanzi eqhelekileyo nexabiso liphantsi kakhulu enesantya esiphezulu sokupholisa, ingakumbi kwindawo yobushushu obuphezulu. Oku kwenza ukuba ikwazi ukupholisa ngokukhawuleza imixokelelwane yentsimbi engama-45#, enceda ekwakheni isakhiwo se-martensitic, ngaloo ndlela iphucula ubulukhuni namandla. Umzekelo, emva kokufakelwa kokugqibela, igiya elincinci le-modulus elenziwe ngentsimbi engama-45# libotshelelwa ngokukhawuleza kwaye lidluliselwe kwigumbi lokuhlambela lamanzi ukuze licime kusetyenziswa umatshini wokucima. Ubulukhuni begiya bunokufikelela ngaphezulu kwe-HRC45, kwaye akukho qhekeko lokucima, kwaye ukusebenza kungcono kunokweenkqubo zemveli. Nangona kunjalo, izinga lokupholisa lamanzi kwindawo yobushushu obuphantsi likhawuleza kakhulu, nto leyo enokubangela uxinzelelo olukhulu lobushushu kunye noxinzelelo lwesakhiwo kumphezulu wesixhobo somsebenzi, nto leyo eyonyusa umngcipheko wokuqhekeka, ingakumbi kwiindawo zemixokelelwane ye-roller ezineemilo ezinzima okanye ubungakanani obukhulu.
