Simba rekuongorora bhaketi zino rinoshanda chiso uye chinhu chakacherwa chekubata, mukuchera kwakakwana kwekuita mumatanho akasiyana ekushanda kwemamiriro ayo akasiyana-siyana ekushungurudzika.Kana zino rezino richitanga kubata chinhu chepamusoro, bucket zino rezino rinokanganiswa zvakasimba nekuda kwekukurumidza kukurumidza.Kana simba rekubereka remazino ebhakiti rakaderera, deformation yeplastiki ichaitika pamuromo.Nekuwedzera kwekunetseka kwekuchera, kudzika kwebhaketi kuchaita shanduko. zino remubhaketi uye zvinhu zvinoitika zvine hukama, zvinogadzira yakakura kwazvo yakanaka extrusion pressure pamusoro, nokudaro inoburitsa simba guru rekukweshana pakati pezino remubhaketi rinoshanda kumeso uye zvinhu. mazino, sarudza bhaketi mazino chokwadi kungwarira daddus kutengesa bhaketi mazino Ndakashandisawo bhakiti mazino ake, mugumisiro zvakanaka!The positive kudzvinyirirwa pamberi kushanda chiso zviri pachena mukuru pane kuti kumusana kushanda chiso, uye pamberi kushanda chiso zvakaipa akasakara. Inogona kutongwa kuti iyo yakanaka kudzvinyirirwa uye friction simba ndiyo huru yekunze mechanical zvinhu zvekukundikana kwemazino ebhakiti, iyo inoita basa guru mukukundikana.
Kuongororwa kwemaitiro: tora sampuli mbiri kubva kumberi uye kumashure zviso zvekushanda zvakateerana, uye uzvikuya zvakadzika kuti zviome kuongororwa.Inowanikwa kuti kuomarara kwemuenzaniso wakafanana kwakasiyana zvakanyanya, uye kutonga kwekutanga ndekwekuti zvinhu hazvisi yunifomu.Zvienzaniso zvaive pasi, zvakasvibiswa uye zvakasvibiswa, uye zvakaonekwa kuti pane miganhu yakajeka pane imwe neimwe sampu, asi miganhu yekuona, iyo macro chikamu chepakati uye chikamu chepakati chakatenderedza chikamu che graf chakasiyana. kwasviba, zvichiratidza kuti chidimbu chacho chingangodaro chakaumbwa. Pamusoro, chikamu chakapoteredzwa chinofanirawo kuva chivharo chakavharidzirwa.Miyedzo yekuoma kumativi ose emuganhu yakaitwa pa hrs-150 digital display rockwell hardness tester uye mhv-2000 digital display microhardness tester, uye misiyano inokosha yakawanikwa.Chikamu chakavharwa chivharo chekuisa uye chikamu chakakomberedza chiri matrix maviri. Iyo huru alloy kuumbwa (chikamu chemazana, %) ndeye 0.38c, 0.91cr, 0.83mn uye 0.92si.Magadzirirwo emagetsi emidziyo yesimbi anoenderana nekuumbwa kwavo uye kupisa kwekupisa maitiro.Kuumbwa kwakafanana uye kusiyana kwekuoma kunoratidza kuti mazino ebhakiti akaiswa mukushandiswa pasina kupisa kwekupisa mushure mekukanda.Kutevera kwezvinyorwa zvekucherechedza kunosimbisa izvi.
Ongororo yesangano yemetallographic yekutarisa yakaratidza kuti iyo substrate inonyanya dema yakanaka lamellar chimiro, seti chidimbu chetishu chine zvikamu zviviri, fritter chena block uye dema, uye chena block kure nechikamu chechikamu chesangano zvakanyanya (uye imwezve microhardness bvunzo inoratidza kuti sangano reiyo ferrite chena zvigamba, nhema yakanaka lamellar chimiro chetroostite kana troostite hybrid ferrilite sangano rekuisa troostite uye troostite inoisa mukati meiyo troostite ferrilite sangano. inofanana neyeimwe chikamu chekuchinja nzvimbo munzvimbo yekupisa yakakanganiswa ye welding.Pasi pekuita kwesimbi yemvura inopisa panguva yekukanda, nzvimbo iyi iri mu austenite uye ferrite maviri-phase zone, apo ferrite yakakura zvakakwana uye microstructure yayo inochengeterwa kusvika kune imwe nzvimbo yekushisa.Nekuti bhakiti zino rusvingo rinenge rakatetepa uye iyo inopinza block volume yakakura, iyo yepakati tembiricha inoumbwa ihuru, iyo yepakati tembiricha inoumbwa ihuru, iyo yepakati tembiricha inoumbwa, iyo yepakati tembiricha inoumbwa, iyo yepakati tembiricha inoumbwa.
Kupfeka bvunzo pa mld-10 kupfeka bvunzo muchina unoratidza kuti kupfeka kuramba matrix uye kupinza kuri nani kupfuura iyo yakadzima 45 simbi pasi pemamiriro ediki mhedzisiro yekupfeka bvunzo.Zvichakadaro, kupfeka kupikisa kwematrix uye kuiswa kwakasiyana, uye iyo matrix inonyanya kusaga kupfuura yekuisa (ona tafura 2) .Kuumbwa pamativi ese maviri e matrix saka iyo inopinza inogona kuvharika iyo ACTS mazino, iyo maininseti inogona kuoneka a chiller.Muchigadziro chekukanda, matrix matrix anonatswa kuti avandudze simba rayo uye kupfeka kusagadzikana.Nekuda kwesimba rekukanda kupisa, chimiro chekuisa chakafanana nechokupisa kupisa kwakakanganiswa nzvimbo.Kana kurapwa kwakakodzera kwekupisa kunoitwa mushure mekukanda kuvandudza chimiro chematrix uye kuisa, kupikisa kupfeka uye hupenyu hwebasa remazino ebhaketi zvichava pachena kuti zvakagadziridzwa.
