Zvikamu zveMichina yekurima yekurima isingapfeki

Tsananguro pfupi:

Muchina wekurima wekubatsira pakupura ivhu chinhu chakakosha chinoshandiswa pakugadzira ivhu chakagadzirirwa kuwedzera magejo emoldboard, anowanzo gadzirwa kana kudhindwa nesimbi yeboron isingaparare zvakanyanya kana simbi ye65Mn manganese. Mupendero wayo wepamusoro unorapwa zvakanyanya nekupisa, zvichiita kuti ivhu rive rakaomarara uye rirambe richikura, zvichiita kuti ivhu ripinde nyore nyore uye richeke masora nemasara ezvirimwa zvinobudirira. Chigadzirwa ichi chine simba guru, kusimba kwakanyanya, kugona kupinza ivhu zvakanaka uye kufukidza, uye kusasimba kwakanyanya, zvichiita kuti chikwanise kurimwa munzvimbo dzisina mvura. Chinoderedza kudzivirira kurimwa uku chichiwedzera kushanda zvakanaka uye kunaka kwekupatsanurwa kwevhu.

Matagi eChigadzirwa

Gejo (rinozivikanwawo segejo remagejo) ndiro chikamu chikuru chekurima chegejo remoldboard, rakaiswa pamberi chaipo pegejo guru. Rinoita mabasa akakosha akadai sekupinza ivhu, kucheka, uye kutungamira. Sechikamu chekutanga chinosangana nevhu zvakananga, mashandiro aro anokanganisa zvakananga kunaka kwebasa, kushandiswa kwesimba, uye hupenyu hwebasa remichina yese yekurima.

Kubva pamaonero ekushanda kwechimiro, basa remugove wegejo rakakosha.

Pakuita basa rechikoro, foshoro yegejo inotanga yapinda muvhu yakatambarara, yocheka pasi pevhu, uye yotungamira ivhu kumadziro egejo kuti ripwanyike nekupwanywa. Kuti rienderane nemamiriro akasiyana evhu uye zvinodiwa pakurima, magejo nemafoshoro akakamurwa kuita mhando dzakasiyana dzemaumbirwo, kunyanya anosanganisira magejo etrapezoidal anoshandiswa pakurima kwakajairika, magejo akachekwa akakodzera ivhu rakaoma, uye magejo etriangular anoshandiswa pakugadzirisa ivhu.

Panyaya yezvinhu uye hunyanzvi, magejo emhando yepamusoro anowanzogadzirwa nesimbi yesimbi inoshanda zvakanyanya, senge 65Mn, 60Si2Mn, nezvimwe zvinhu. Mukugadzira, vagadziri vepamusoro vanozoshandisa tekinoroji yekugadzira uye vanoshandisa michina mikuru ye tonnage yekugadzira kamwe chete kuchengetedza kusimba kwechimiro chesimbi, nokudaro zvichiwedzera zvakanyanya kuramba kusimba uye kuramba kupfeka kwechigadzirwa.

Mushure mekuumba, chigadzirwa chinofanirawo kupiswa zvakanyatsonaka kuti chiwane kuomarara kwakakodzera kweHRC 38-50. Kunyangwe ichivimbisa kuomarara kwakakwana, inewo kuomarara kwakanaka kudzivirira kutyoka kusingatani kuputsika.

Kuti iwedzere nguva yayo yekushanda, magejo nemafoshoro emazuva ano anosanganisira pfungwa dzakasiyana-siyana dzisingapfeki mumagadzirirwo adzo. Semuenzaniso, kushandisa dhizaini yekusimbisa yemuno kuunganidza zvinhu zvisingapfeki munzvimbo dzakanyanya kupfekwa (senge matipi efoshoro); Zvimwe zvigadzirwa zvinotsigirawo kupfekwa kuti zvishandiswe. Kana rimwe divi rikapera, rinogona kupfekwa uye kuiswa kuti rirambe richishandisa rimwe divi refoshoro, zvichipeta hupenyu hwaro kaviri.
