Hupenyu hwesevhisi hwesimende carbide molds hune hukama nemamiriro ebasa, dhizaini nekugadzira maitiro, kuisirwa, kushandiswa uye kuchengetedza mold. Naizvozvo, kuvandudza hupenyu hwesevhisi yezviumbwa, matanho anowirirana ekuvandudza aya mamiriro anofanirwa kutorwa. Zvinhu zvikuru zvinokanganisa hupenyu hwebasa rezviumbwa zvinotsanangurwa sezvinotevera.
(1) Kupesvedzera kwekugadzira dhizaini dhizaini pahupenyu hwesevhisi yezviumbwa Kunzwisisika kwechimiro chechimiro chine simba guru pakutakura kugona kwezviumbwa; chimiro chisina musoro chinogona kukonzera kushushikana kwakanyanya kana kupisa kwakanyanya kwekushanda, nekudaro kushatisa mamiriro ekushanda ezviumbwa uye kukonzeresa kutadza kusati kwasvika kweiyo molds. Chimiro che mold chinosanganisira chimiro chejometri chechikamu chinoshanda che mold, saizi yekona yekuchinja, chimiro che clamping, gwara uye ejection mechanism, gap rekuumbwa, chiyero chechikamu chepunch, iyo yekupedzisira face inclination angle, kuvhurwa kwematanho emvura inotonhorera uye zvimiro zvegungano mune inopisa kushanda molds, nezvimwe.
(2) Pesvedzero yesimbi yakasimwa carbide mold zvinhu pahupenyu hwesevhisi yezviumbwa Kufuridzirwa kwezvinhu zvehuvhu pahupenyu hwesevhisi yezviumbwa iratidziro yakazara yezvinhu zvakaita semhando yemhando yemhando, kemikari, chimiro chesangano, kuoma uye metallurgical mhando, pakati peiyo mhando yezvinhu uye kuoma zvine pesvedzero iri pachena. Mhedzisiro yemhando yezvinhu mold pane hupenyu hwekuumbwa yakakura kwazvo.
Nokudaro, pakusarudza zvinhu zvekuumbwa, zvinhu zvekugadzira zvinofanira kusarudzwa zvakakodzera maererano nehukuru hwebatch yezvikamu. Kuoma kwezvikamu zvekushanda zvemuumbi kunewo simba guru pahupenyu hwehuputi, asi iyo yakakwirira kuoma, iyo yakareba hupenyu hwehuputi. Zvinogona kuonekwa kuti kuoma kwecemented carbide molds kunofanirwa kugadziriswa maererano nekugadzira zvinhu uye mafomu ekukundikana, uye kuoma, simba, kuomarara, kupfeka kusagadzikana, kuneta kuramba, nezvimwe zvinofanirwa kunyatsoenderana nezvinodiwa zvekuumba. Kufuridzirwa kwesimbi yehutano hwezvinhu zvehupenyu hwehuputi haigoni kuregererwa, kunyanya high-carbon alloy simbi, iyo ine zvakawanda zvemetallurgical defects, iyo inowanzova iyo inokonzera mold quenching kuputika uye kukuvara kwekutanga kune mold. Nokudaro, kuvandudza metallurgical quality yezvinyorwa zvakare chinhu chinokosha chekuvandudza hupenyu hwehutu.
Chii chinonzi fracture kuramba simba recemented carbide molds?
Imwe-nguva brittle fracture kuramba: Zviratidzo zvinogona kuratidza iyo imwe-nguva brittle fracture resistance ye simende carbide molds inguva imwe chete inokanganisa kuputsika basa, kumanikidza simba uye kubhenda simba.
Kuneta fracture kuramba: Inoratidzirwa nehuwandu hwekutyoka matenderedzwa pasi peimwe cyclic mutoro kana kukosha kwemutoro unokonzera kuti specimen iputse pane yakatarwa nhamba yematenderedzwa. Iyo simende ye carbide mold inogona kuratidzwa nezviratidzo zvakati wandei senge simba diki rakawanda rinokanganisa kutsemuka basa kana kuwanda kunokanganisa hupenyu hwekutyoka, kusimba uye kumanikidza kuneta simba kana kuneta hupenyu, kubata kuneta simba kana kubata kuneta hupenyu. Crack fracture resistance: Kana ma microcracks atovepo mu simende ye carbide mold, kuramba kwayo kuputsika kunodzikira zvakanyanya. Naizvozvo, zvakasiyana-siyana zvinopikisa kuputsika zvakaedzwa pazvienzaniso zvakatsetseka hazvigone kushandiswa kuongorora kupokana kwekuputsika kwemuviri wekutsemuka. Zvinoenderana nedzidziso yekutyoka mechanics, iyo fracture toughness index inogona kushandiswa kuratidza kushomeka kwemuviri wekutsemuka.
