(1) Kulimba mtima (σb) :mphamvu yaikulu (Fb) ya chitsanzo pa nthawi ya kusweka kwamphamvu imagawidwa ndi kupanikizika (σ) kwa gawo loyambirira la mtanda (So) la chitsanzo.Gawo la mphamvu yamakokedwe (σb) ndi N/mm2(MPA).Zimayimira mphamvu yaikulu yazitsulo zachitsulo kuti zithetse kuwonongeka pansi pa zovuta.Kumene: Fb-- mphamvu yayikulu yotsatiridwa ndi chitsanzocho ikasweka, N (Newton); So-- Gawo loyambirira lachitsanzo, mm2.
(2) Malo otulutsa (σ S) :nsonga yokolola yachitsulo chokhala ndi zochitika zokolola.Ndilo kupsinjika komwe chitsanzocho chingathe kupitiriza kutambasula popanda kuonjezera mphamvu (kusunga nthawi zonse) panthawi yopuma.Ngati mphamvu ikuchepa, zokolola zapamwamba ndi zochepa ziyenera kusiyanitsa.Gawo la zokolola ndi NF/mm2(MPA).Malo okolola apamwamba (σ SU) ndizovuta kwambiri zomwe zitsanzo zisanaperekedwe ndipo mphamvu ikutsika kwa nthawi yoyamba.Malo otsika (σ SL) : kupanikizika kochepa mu gawo la zokolola pamene zotsatira zoyamba zosakhalitsa sizikuganiziridwa.Kumene Fs ndi mphamvu zokolola (nthawi zonse) ya chitsanzo panthawi yamphamvu, N (Newton) Momwemonso ndi gawo loyambirira lachitsanzo, mm.2.
(3) Kutalikirana pambuyo pakusweka :(σ)pakuyezetsa kwamakomedwe, elongation ndi kuchuluka kwa kutalika komwe kumachulukitsidwa ndi mtunda wokhazikika wa chitsanzo pambuyo pa kuthyoka poyerekeza ndi kutalika kwa mtunda woyambira wokhazikika.Gawoli ndi %.Kumene: L1-- mtunda wa chitsanzo pambuyo kusweka, mm;L0-- Utali woyambirira wa mtunda wa zitsanzo, mm.
(4) Kuchepetsa gawo :(ψ)pakuyesa kolimba, kuchuluka kwa kuchepetsedwa kwakukulu kwa gawo la magawo apakati pamtunda wocheperako wa fanizolo pambuyo pokokedwa ndipo gawo loyambilira la gawolo limatchedwa kuchepetsa gawo.ψ imawonetsedwa mu %.Kumene, S0-- gawo loyambirira lachitsanzo, mm2;S1-- Malo ocheperako pang'onopang'ono pamtunda wocheperako wa chitsanzo mutasweka, mm2.
(5) Kuuma index:kuthekera kwa zida zachitsulo kukana zinthu zolimba kuti zilowerere pamwamba, zomwe zimadziwika kuti kuuma.Malingana ndi njira yoyesera ndi kuchuluka kwa ntchito, kuuma kungathe kugawidwa mu Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro hardness ndi kutentha kwakukulu.Zomwe zimagwiritsidwa ntchito popanga zitoliro zimakhala ndi brinell, rockwell, Vickers kuuma 3 mitundu.
(6) Kuuma kwa Brinell (HB):ndi mainchesi ena a mpira wachitsulo kapena mpira wolimba wa aloyi, ndi mphamvu yoyesera yodziwika (F) yokanikizidwa pachitsanzo, itatha nthawi yoikidwiratu kuti muchotse mphamvu yoyesa, kuyeza kwachitsanzo cham'mimba mwake (L).Nambala ya kuuma kwa Brinell ndi quotient ya mphamvu yoyesera yogawidwa ndi dera la indentation sphere.Kuwonetsedwa mu HBS, gawoli ndi N/mm2(MPA).
Zimango zimatha kanasonkhezereka zitsulo chitoliro, Magwiridwe kwambiri
(1) Mpweya;Kukwera kwa carbon, kumakhala kovuta kwambiri, koma pulasitiki ndi ductile ndi yochepa.
(2) Sulfure;Ndi zinyalala zovulaza muzitsulo, zitsulo zokhala ndi sulfure wapamwamba kwambiri pakuwongolera kutentha kwambiri, zosavuta kusweka, zomwe nthawi zambiri zimatchedwa brittleness yotentha.
(3) Phosphorus;Ikhoza kuchepetsa kwambiri pulasitiki ndi kulimba kwachitsulo, makamaka kutentha kochepa, komwe kumakhala koopsa kwambiri, ndipo chodabwitsachi chimatchedwa kuzizira kozizira.Muzitsulo zapamwamba, sulfure ndi phosphorous ziyenera kuyendetsedwa mosamalitsa.Koma Komano, otsika mpweya zitsulo lili apamwamba sulfure ndi phosphorous, akhoza kudula ake zosavuta kuswa, kusintha machinability zitsulo ndi yabwino.
(4) Manganese;Ikhoza kusintha mphamvu ya chitsulo, imatha kufooketsa ndi kuthetsa mavuto a sulfure, ndipo imatha kusintha kuuma kwachitsulo, chitsulo cha aloyi chokhala ndi manganese apamwamba (chitsulo chachikulu cha manganese) chimakhala ndi kukana kwabwino ndi zinthu zina zakuthupi.
(5) Silikoni;Ikhoza kusintha kuuma kwa chitsulo, koma pulasitiki ndi kuuma kumachepa, zitsulo zamagetsi zimakhala ndi silicon, zimatha kusintha zinthu zofewa za maginito.
(6) Tungsten;Ikhoza kusintha kuuma kofiira, mphamvu yamafuta ndi kuvala kukana kwachitsulo.
(7) Chromium;Ikhoza kusintha kuuma ndi kuvala kukana kwachitsulo, kupititsa patsogolo kukana kwa dzimbiri ndi kukana kwa okosijeni kwachitsulo.
(8) Zinc;Kuti apititse patsogolo kukana kwa dzimbiri, chitoliro chonse chachitsulo (chitoliro chakuda) chimalimbikitsidwa.kanasonkhezereka zitsulo chitoliro lagawidwa mitundu iwiri ya otentha kuviika kanasonkhezereka zitsulo ndi magetsi zitsulo nthaka, otentha kuviika kanasonkhezereka wosanjikiza wandiweyani, magetsi kanasonkhezereka mtengo ndi otsika, kotero pali kanasonkhezereka zitsulo chitoliro.
Zimango zimatha kanasonkhezereka zitsulo chitoliro，Kuyeretsa njira
1. ntchito yoyamba ya zosungunulira kuyeretsa zitsulo pamwamba, pamwamba pa organic kanthu kuchotsa,
2. Kenako gwiritsani ntchito zida kuchotsa dzimbiri (waya burashi), chotsani sikelo yotayirira kapena yopendekeka, dzimbiri, zitsulo zowotcherera, etc.,
3. kugwiritsa ntchito pickling.
Galvanized imagawidwa kukhala plating yotentha ndi plating yozizira, plating yotentha sivuta kuchita dzimbiri, kuzizira kozizira ndikosavuta kuchita dzimbiri.
Zimango zimatha kanasonkhezereka zitsulo chitoliro，Kulumikizana mu poyambira anagubuduza mode
(1) Kuwotcherera kwa Groove
1, chitoliro pakamwa kuthamanga poyambira mbali ya mkati khoma kuwotcherera kapamwamba akupera yosalala, kuchepetsa poyambira kugubuduza kukana.
2. Sinthani olamulira zitsulo chitoliro ndi poyambira anagubuduza zipangizo, ndipo amafuna mlingo wa zitsulo chitoliro ndi poyambira anagubuduza zipangizo.
3, sinthani liwiro la tanki yokakamiza, nthawi yowumba ya tanki yokakamiza siyingadutse zomwe zimaperekedwa, yunifolomu komanso mphamvu pang'onopang'ono.
(2) Kugudubuza njira zitsulo chitoliro kusweka
1. Sambani nthiti zowotcherera pakhoma lamkati la poyambira pakamwa pazitsulo zachitsulo kuti muchepetse kukana kwa poyambira.
2. Sinthani olamulira zitsulo chitoliro ndi poyambira anagubuduza zipangizo, ndipo amafuna mlingo wa zitsulo chitoliro ndi poyambira anagubuduza zipangizo.
3, sinthani kuthamanga kwa thanki yothamanga, kuthamanga kwa thanki yothamanga sikungadutse zomwe zimaperekedwa, yunifolomu komanso mphamvu pang'onopang'ono.
4. Yang'anani m'lifupi ndi mtundu wa chodzigudubuza chothandizira ndi choponderetsa cha zida za groove kuti muwone ngati zodzigudubuza ziwirizo sizikugwirizana ndi kukula kwake ndikuyambitsa zochitika za occlusal.
5. Onani ngati poyambira wa chitsulo chitoliro chatchulidwa ndi vernier caliper.
(3) Groove akugubuduza akamaumba makina ayenera kukwaniritsa zofunika izi
1. Pamwamba kuchokera kumapeto kwa chitoliro mpaka poyambira pazikhala mosalala komanso opanda zingwe zopindika komanso zopindika.
2. Pakati pa groove iyenera kukhala yokhazikika ndi khoma la chitoliro, m'lifupi ndi kuya kwa groove ziyenera kukwaniritsa zofunikira, ndikuwona ngati mtundu wa clamp uli wolondola.
3. Ikani mafuta pa mphete yosindikizira ya rabara ndikuwona ngati mphete yosindikizira ya rabala yawonongeka.Mafuta amafuta sayenera kugwiritsidwa ntchito popangira mafuta.
