Zino chimwe chezvikamu zvakakosha pane chekuchera, bhaketi refoshoro rakafanana nemazino evanhu, uyewo akapfeka zvikamu, rinoumbwa nemazino uye zino retip musanganiswa dipper mazino, zvose nepini shaft link.Nemhaka yebhakiti zino rinopfeka kukundikana chikamu ndiro zino, chero bedzi kuchinjwa nemuromo.
Nekuda kwesimba rematambudziko emari, nyika yedu inoshingairira kuwedzera kudiwa kwemba, inoita kuti musika wepamusha wemazino emugomo uve nemhedzisiro yakanaka, ita vazhinji vagadziri vemazino emubhaketi mumusika tarisiro yakanaka!
A: kushushikana kwekuongorora kwebhaketi zino rinotarisana nekusangana nechikamu chemigodhi, mumatanho ekushanda akasiyana-siyana panguva yekuchera simba rakasiyana.Zino rinotanga kusangana nepamusoro pezvinhu, nekuda kwekukurumidza, chikamu chezino chebhaketi chakarova kubva kune chakasimba.Kana yakaderera goho simba bhakiti zino, achabudisa epurasitiki deformation mumuromo.Pamwe pamwe nekuwedzera kwekudzika kwemigodhi, iyo bucket zino rekushushikana kugovera kuchachinja.Kana iyo bhaketi zino rekucheka zvinhu, kufamba kwehama kunoitika, iyo bhaketi zino uye zvinhu zvinogadzira zvakakura kwazvo ndeye extrusion kudzvanywa pamusoro, saka iro bhaketi zino rinotarisana uye rinoburitsa kurira kukuru pakati pezvinhu.Kana iyo zvinhu idombo rakaoma, kongiri, nezvimwewo, simba rekupokana richave rakakura.Migumisiro yeiyi nzira kashoma uye pamusoro pechiso chezino remubhaketi kubva pakupera uye kubvaruka, nokudaro inoburitsa miforo yakadzika yakadzika.Kuumbwa kwe dipper mazino kwakanaka kuhurefu hwehupenyu hwebasa remazino, sarudza zino remugomo, hongu, kunyanya kungwarira idiot inotengeswa bhaketi zino rake bhaketi zino ndakashandisawo, mhedzisiro yacho yakanaka!Chiso mushure mekumanikidzwa kushanda chiso chiri pachena chakakwira kupfuura kare, pamberi pekushanda kumeso kwakasakara uye kubvaruka, uye inogona kuona iyo yakanaka kudzvanywa uye kukwesha simba ndiyo huru yekutadza modes yebucket zino rekunze mechanic factor, inobata basa guru mukuita kugadzirwa.
2: Kuongororwa kwemaitiro emasampuli maviri kubva kune imwe neimwe zvakateerana pamberi uye mushure mekushanda kumeso, yakatsetseka kuomarara bvunzo.Inowanikwa pane imwecheteyo kuomarara musiyano wakakura kwazvo, yekutanga kutonga haina kuenzana.Sample pakukuya, polishing, etching, yakaona kuti imwe neimwe sampuli pamiganhu iri pachena, inongorongedza zvikamu zvakasiyana.Kubva pakuona macroscopic, iyo yakachenuruka grey, yakatenderedza chikamu chepakati, ine yakasviba ruvara inoratidza kuti chinhu chingangove chakaiswa kukanda, pamusoro pepamusoro, chakakomberedzwa zvikamu zvinofanirwawo kuve seti zvidimbu.MuHRS - 150 digital rockwell hardness tester uye MHV - 2000 digital display microhardness mita pamutsara kumativi ose ekuedza kwekuoma, zvakateerana, zvakaratidza kusiyana kukuru (ona tafura 1).Kuburikidza nekuongorora kuri pamusoro kwakasimbisa kuti dipper mazino akaiswa chidimbu chechimiro.Vhara mamwe acho akaiswa chidimbu, chikamu chiri matrix chakavapoteredza.Kuumbwa kwezvose zviri zviviri pedyo, zvakadai seCr, Mn, Si alloying elements, iyo huru alloy elements (mass fraction, %) ye 0.38 C, 0.91 0.83 0.83 Mn, Cr, Si.Iyo mechanical properties yesimbi zvinhu zvinoenderana nekugadzirwa kwezvinhu uye kupisa kurapwa.Misiyano pakati pekuumbwa kwakafanana uye kuoma kwemazino emubhaketi pasina kupisa kupisa kunoshandiswa mushure mekukanda.Sangano riri seri kwecherechedzo rinosimbisawo pfungwa iyi.
