Inxalenye ephezulu yepleyiti eshukumayo yomhlathi we-jaw crusher idityaniswe ne-eccentric shaft, indawo esezantsi ixhaswa yiplate yokutyhala, kwaye ipleyiti esisigxina yomhlathi igxininise kwisakhelo. Xa i-eccentric shaft ijikeleza, ipleyiti eshukumayo yomhlathi ithwala intshukumo ye-extrusion yezinto, ngelixa ipleyiti esisigxina yomhlathi ithwala isenzo sokusika esilayidileyo. Njengenxalenye enezinga eliphezulu lokuphuka kwemihlathi kunye nokugqoka, ukukhethwa kwezinto zomhlathi kuhambelana neendleko kunye nenzuzo yabasebenzisi.
Imanganese ephezuluintsimbi Intsimbi yemanganese ephezulu yinto yemveli yepleyiti yomhlathi wemihlathi, inefuthe elihle lokumelana nomthwalo, kodwa ngenxa yesizathu sesakhiwo sokutyumza, i-Angle phakathi kwepleyiti yomhlathi eguquguqukayo kunye nesigxina inkulu kakhulu, kulula ukubangela ukutyibilika kwe-abrasive. ukuya deformation ukuqina akwanelanga ukwenza ipleyiti yomhlathi umphezulu ubulukhuni iphantsi, abrasive short-uluhlu ukusika, ipleyiti yomhlathi banxibe ngokukhawuleza. Ukuze kuphuculwe ubomi benkonzo yeplate yomhlathi, kuye kwaphuhliswa izinto ezahlukeneyo zeplate yomhlathi, njengokongeza i-Cr, Mo, W, Ti, V, Nb kunye nezinye izinto ukuguqula intsimbi ephezulu ye-manganese, kunye nokuqiniswa kwe-dispersion. unyango lwentsimbi yemanganese ephezulu ukuphucula ubulukhuni bayo bokuqala kunye nokomelela kwesivuno. Ukongeza, i-composite yensimbi ye-manganese ephakathi, intsimbi ephantsi ye-alloy, intsimbi ephezulu ye-chromium kunye nentsimbi ephezulu ye-manganese iye yaphuhliswa, kwaye iziphumo ezilungileyo zifunyenwe kwimveliso.
I-China Manganese Steel yaqalwa okokuqala yiNkampani ye-Climax Molybdenum kwaye yadweliswa ngokusemthethweni kwi-patent yase-United States ngo-1963. Indlela yokuqina ihamba ngolu hlobo lulandelayo: emva kokunciphisa umxholo we-manganese, ukuzinza kwe-austenite kuncipha, kwaye xa iphantsi kwempembelelo okanye ukuguga, I-austenite ixhomekeke kwinguqu ye-deformation-induced martensitic, ephucula ukuxhathisa kwayo ukunxiba. Ukubunjwa okuqhelekileyo kwensimbi ye-manganese (%) : 0.7-1.2C, 6-9Mn, 0.5-0.8Si, 1-2Cr kunye nezinye izinto zokulandelela i-V, i-Ti, i-Nb, umhlaba onqabileyo kunye nokunye. Ubomi bokwenene benkonzo yentsimbi ephakathi yentsimbi ye-manganese ipleyiti yomhlathi ingaphezulu kwe-20% ephezulu kuneyentsimbi ephezulu ye-manganese, kwaye iindleko zifaniswa nentsimbi ephezulu ye-manganese.
03 I-iron ye-chromium ephezulu yentsimbi Nangona i-chromium ephezulu yentsimbi inokunganyangeki okuphezulu, kodwa ngenxa yobunzima bayo, ukusetyenziswa kwentsimbi ephezulu ye-chromium njengepleyiti yomhlathi akuphumeleli iziphumo ezilungileyo. Kwiminyaka yakutshanje, i-chromium ephezulu ephoswe ngentsimbi okanye ebotshelelwe kwipleyiti yomhlathi yentsimbi ephezulu yemanganese ukwenza ipleyiti yomhlathi kabini, ukuxhathisa ukunxitywa kwesalamane ukuya kumaxesha ama-3, ukuze ubomi benkonzo yepleyiti yomhlathi bunyuke kakhulu. Oku kuyindlela efanelekileyo yokuphucula ubomi benkonzo yeplate yomhlathi, kodwa inkqubo yokuvelisa inzima kakhulu, ngoko kunzima ukuyenza.
Ikhabhoni ephantsi kwentsimbi ephoswe ngentsimbi ikwayinto esetyenziswa ngokubanzi engagugiyo, ngenxa yokuqina kwayo okuphezulu (≥45HRC) kunye nokuqina okufanelekileyo (≥15J/cm²), inokumelana nokusikwa kwemathiriyeli kunye nokuphindaphinda okubangelwa kukudinwa, oko kubonisa okulungileyo. nxiba ukumelana. Ngelo xesha, i-carbon low low alloy cast iron cast nayo ingahlengahlengiswa ngokubunjwa kunye nenkqubo yonyango lokushisa, ukwenzela ukuba ukuqina kunye nokuqina kunokutshintsha kuluhlu olukhulu ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza. Uvavanyo lokusebenza lubonisa ukuba ubomi benkonzo yentsimbi yentsimbi ephakathi kwekhabhoni ephantsi ingaphezulu kwamaxesha ama-3 ubude kunobo bentsimbi.manganese ephezuluintsimbi.
Iingcebiso zokukhetha ipleyiti yomhlathi:
Isishwankathelo, ukukhethwa kwezinto zepleyiti yomhlathi ngokufanelekileyo ukuhlangabezana neemfuno zobunzima obuphezulu kunye nokuqina okuphezulu, kodwa ukuqina kunye nokuqina kwezinto zihlala ziphikisana, ngoko ke ekukhethweni kwangempela kwezinto, kufuneka siqonde ngokupheleleyo iimeko zokusebenza, ezifanelekileyo. ukhetho lwezixhobo.
I-1) Umthwalo wempembelelo yenye yezinto ezibalulekileyo ekufuneka ziqwalaselwe ekukhethweni kwezinto ezifanelekileyo. Ubukhulu benkcazo, ubunzima beendawo ezinxitywayo, ukunyanzeliswa kwezinto eziphukileyo, kunye nomthwalo omkhulu wempembelelo. Ngeli xesha, ukuguqulwa okanye ukusabalalisa-komelezwe intsimbi ephezulu ye-manganese isenokusetyenziswa njengento yokukhethwa kwezinto. Kwi-crushers ephakathi kunye nencinci, umthwalo wempembelelo owenziwe ngamacandelo alula okugaya awukho mkhulu kakhulu, ukusetyenziswa kwentsimbi ephezulu ye-manganese, kunzima ukwenza ukuba kusebenze ngokupheleleyo ukuqina. Ngaphantsi kweemeko ezinjalo zokusebenza, ukhetho lwentsimbi ephakathi kwekhabhoni ephantsi okanye i-chromium ephezulu yentsimbi / i-low alloy iron composite material inokufumana izibonelelo ezilungileyo zobugcisa kunye nezoqoqosho.
2) Ukubunjwa kwezinto kunye nobunzima bayo zizinto ezingenakunakwa ekukhethweni kwezinto ezifanelekileyo. Ngokubanzi, ukuphakama kobunzima bezinto eziphathekayo, ukuphakama kweemfuno zobunzima bezinto ezilula ukunxiba, ngoko ke phantsi kweemeko zokuhlangabezana neemfuno zobunzima, izinto ezinobunzima obuphezulu kufuneka zikhethwe kangangoko kunokwenzeka. .
3) Ukukhethwa kwezinto ezifanelekileyo kufuneka kuthathelwe ingqalelo indlela yokunxiba yeendawo ezigugileyo ngokulula. Ukuba ukugqoka ukusika kuyona nto iphambili, ubunzima kufuneka buqwalaselwe kuqala xa ukhetha izinto. Ukuba ukunxiba kweplastiki okanye ukukhathala kukunxiba okuphambili, iplastiki kunye nokuqina kufuneka kuqwalaselwe kuqala xa ukhetha izinto. Kakade ke, ekukhethweni kwezinto eziphathekayo, kufuneka kwakhona kuqwalaselwe ingqiqo yenkqubo yayo, kulula ukucwangcisa imveliso kunye nokulawula umgangatho.
