Zino chimwe chezvikamu zvakakosha pane chekuchera, bhaketi refoshoro rakafanana nemazino evanhu, rakapfekawo zvikamu, rinoumbwa nemazino uye zino retip musanganiswa dipper mazino, zvose nepini shaft link. Nemhaka yebhakiti zino rinopfeka kukundikana chikamu ndiro zino, chero bedzi kutsiva 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, zino remugomo uye zvinhu zvinoburitsa zvakakura zvakanyanya kudzvinyirirwa pamusoro, saka zino remugomo rinotarisana uye rinoburitsa kupesana kukuru pakati pezvinhu. Kana zvinhu zvacho 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 kwemazino edipper 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 kudzvanywa kwakanaka uye kukwesha simba ndiyo huru yekutadza modes yebucket zino rekunze michina zvinhu, inoita basa guru mukuita kugadzirwa.
2: Kuongororwa kwemaitiro emasampuli maviri kubva kune imwe neimwe zvakateerana pamberi uye mushure mekushanda kumeso, yakatsetseka kuomarara bvunzo. Inowanikwa pane imwechete sampu yekuomarara musiyano wakakura kwazvo, mutongo wekutanga hauna kuenzana. Sample pakukuya, polishing, etching, yakaona kuti sampuli yega yega 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, zvakatevedzana, 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 chakavakomberedza. 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 kurapa maitiro. Misiyano pakati pekuumbwa kwakafanana uye kuoma kwemazino ebhaketi pasina kupisa kupisa kunoshandiswa mushure mekukanda. Sangano riri seri kwecherechedzo rinosimbisawo pfungwa iyi.
