Ibikoresho bya mashini ya
(1) Imbaraga zingana (σb):imbaraga ntarengwa (Fb) yikigereranyo mugihe cyo kuvunika kwinshi kugabanijwe na stress (σ) yumwimerere wambukiranya igice (So) yikigereranyo.Igice cyingufu zingana (σb) ni N / mm2(MPa).Yerekana ubushobozi ntarengwa bwibikoresho byicyuma kugirango birwanye ibyangiritse.Aho: Fb-- imbaraga ntarengwa zitwarwa nicyitegererezo iyo kimenetse, N (Newton); So-- Umwimerere wambukiranya igice cyicyitegererezo, mm2.
(2) Gutanga umusaruro (σ S):umusaruro wibintu byicyuma hamwe numusaruro.Nibibazo byerekana urugero rushobora gukomeza kurambura nta kongera imbaraga (guhora uhoraho) mugihe cyimikorere.Mugihe imbaraga zagabanutse, ingingo zo hejuru no hasi zitanga umusaruro zigomba gutandukanywa.Igice cyo gutanga umusaruro ni NF / mm2(MPa).Umusaruro wo hejuru (σ SU) ni stress ntarengwa mbere yuko urugero rutanga kandi imbaraga zigabanuka kunshuro yambere.Ingingo yo gutanga umusaruro muke (σ SL): guhangayikishwa byibuze murwego rwo gutanga umusaruro mugihe ingaruka yambere yinzibacyuho itarebwa.Aho Fs nimbaraga zitanga umusaruro (zihoraho) zicyitegererezo mugihe cyimyitozo, N (Newton) Niko rero umwimerere wambukiranya igice cyikigereranyo, mm2.
(3) Kurambura nyuma yo kuvunika: (σ)mu kizamini cya tensile, kurambura ni ijanisha ryuburebure bwiyongereye nintera isanzwe yikigereranyo nyuma yo kuvunika ugereranije nuburebure bwintera yambere.Igice ni%.Aho: L1-- intera yikigereranyo nyuma yo kumena, mm;L0-- Intera yumwimerere uburebure bwa sample, mm.
(4) Kugabanya igice: (ψ)mu kizamini cya tensile, ijanisha ryo kugabanuka kwinshi kwagace kambukiranya igice kuri diametre yagabanijwe yikigereranyo nyuma yo gukururwa kandi agace kambere kambukiranya igice bita kugabanya igice.expressed bigaragarira muri%.Aho, S0-- umwimerere wambukiranya igice cyicyitegererezo, mm2;S1-- Agace ntarengwa kambukiranya igice kuri diameter yagabanutse yikigereranyo nyuma yo kumena, mm2.
(5) Icyerekezo gikomeye:ubushobozi bwibikoresho byibyuma byo kurwanya ibintu bikomeye kugirango berekane hejuru, bizwi nkubukomere.Ukurikije uburyo bwikizamini hamwe nubunini bwakoreshejwe, ubukana burashobora kugabanywamo ubukana bwa Brinell, ubukana bwa Rockwell, ubukana bwa Vickers, ubukana bwa Shore, ubukana bwa micro hamwe nubushyuhe bwo hejuru.Mubisanzwe bikoreshwa mu kuvoma ibikoresho bifite brinell, rockwell, Vickers gukomera ubwoko 3.
(6) Gukomera kwa Brinell (HB):hamwe na diameter runaka yumupira wibyuma cyangwa umupira ukomeye, hamwe nimbaraga zageragejwe (F) zashyizwe hejuru yicyitegererezo, nyuma yigihe cyagenwe cyo gukuraho imbaraga zipimisha, gupima urugero rwikigereranyo cya diameter (L).Umubare ukomeye wa Brinell ni igipimo cyimbaraga zipimisha zigabanijwe nubuso bwubuso bwa indentation.Byerekanwe muri HBS, igice ni N / mm2(MPa).
Ibikoresho bya mashini yumuringa wicyuma impact Ingaruka yimikorere
(1) Carbone;Iyo karubone iri hejuru, ibyuma birakomera, ariko plastike ntigabanuka.
(2) Amazi ya sufuru;Ese imyanda yangiza mubyuma, ibyuma hamwe na sulferi nyinshi mugutunganya ubushyuhe bwo hejuru, byoroshye gucika, mubisanzwe byitwa brittleness.
(3) Fosifore;Irashobora kugabanya cyane plastike nubukomezi bwibyuma, cyane cyane kubushyuhe buke, bikaba bikomeye, kandi iki kintu cyitwa ubukonje bukabije.Mubyuma byujuje ubuziranenge, sulfure na fosifore bigomba kugenzurwa cyane.Ariko kurundi ruhande, ibyuma bike bya karubone birimo sulfure na fosifore nyinshi, birashobora gutuma kuyikata byoroshye kumeneka, kugirango imikorere yicyuma ari nziza.
(4) Manganese;Irashobora kunoza imbaraga zicyuma, irashobora guca intege no gukuraho ingaruka mbi za sulfuru, kandi irashobora kunoza ubukana bwibyuma, ibyuma bivanze cyane hamwe na manganese nyinshi (ibyuma bya manganeze) bifite imbaraga zo kwihanganira kwambara nibindi bintu bifatika.
(5) Silicon;Irashobora kunoza ubukana bwibyuma, ariko plastike nubukomezi bigabanuka, ibyuma byamashanyarazi birimo silikoni runaka, birashobora kunoza imiterere ya magneti yoroshye.
(6) Tungsten;Irashobora kunoza ubukana butukura, imbaraga zumuriro no kwambara ibyuma.
(7) Chromium;Irashobora kunoza ubukana no kwambara ibyuma, kunoza ruswa no kurwanya okiside yicyuma.
(8) Zinc;Kugirango tunonosore kurwanya ruswa, umuyoboro rusange wibyuma (umuyoboro wumukara) urashishwa.Umuyoboro w'icyuma ugabanijwemo ubwoko bubiri bw'icyuma gishyushye gishyizwe hamwe nicyuma cyamashanyarazi zinc, icyuma gishyushye cya galvanizasi yubushyuhe, igiciro cyamashanyarazi ni gito, nuko hariho umuyoboro wibyuma.
Ibikoresho bya mashini yumuringa wicyuma method Uburyo bwo kweza
1. ikoreshwa ryambere ryogusukura ibyuma bisukura ibyuma, hejuru yikuramo ibintu kama,
2. hanyuma ukoreshe ibikoresho kugirango ukureho ingese (brush wire), ukureho igipimo cyoroshye cyangwa kigoramye, ingese, gusudira, n'ibindi,
3. gukoresha ibirungo.
Galvanised igabanijwemo isahani ishyushye hamwe no gukonjesha imbeho, isahani ishyushye ntabwo yoroshye kubora, isahani ikonje iroroshye kubora.
Ibikoresho bya tekinike yumuringa wicyuma , Guhuza muburyo bwo kuzunguruka
(1) Groove weld yamenetse
1, umuyoboro wumunwa wumuyoboro igice cyurukuta rwimbere rwo gusudira urusenda rusya neza, kugabanya kwihanganira kuzunguruka.
2. Hindura umurongo wibikoresho byicyuma hamwe nibikoresho bizunguruka, kandi bisaba urwego rwibikoresho byicyuma nibikoresho bizunguruka.
3, hindura umuvuduko wikigega cyumuvuduko, igihe cyo gushushanya ikigega cyumuvuduko ntigishobora kurenga kubiteganijwe, imbaraga imwe kandi itinda.
(2) Kuzunguruka umuyoboro wicyuma kuvunika
1. Shyira imbavu zo gusudira kurukuta rwimbere rwumuvuduko wumuvuduko kumunwa wicyuma kugirango ugabanye kwihanganira kuzunguruka.
2. Hindura umurongo wibikoresho byicyuma hamwe nibikoresho bizunguruka, kandi bisaba urwego rwibikoresho byicyuma nibikoresho bizunguruka.
3, hindura umuvuduko wikigega, umuvuduko wikigega ntushobora kurenga kubiteganijwe, imbaraga imwe kandi itinda.
4. Reba ubugari n'ubwoko bwa roller yingoboka hamwe nigitutu cyumuvuduko wibikoresho bya groove kugirango urebe niba ibizingo byombi bidahuye mubunini kandi bitera ibintu bidasanzwe.
5. Reba niba igikoni cyumuyoboro wicyuma cyerekanwe na vernier caliper.
(3) Imashini ibumba imashini igomba kuzuza ibisabwa bikurikira
1. Ubuso buva kumuyoboro ujya kumurima bugomba kuba bworoshye kandi butarimo conve-convex nibimenyetso bizunguruka.
2. Hagati ya shobuja igomba kuba yibanze hamwe nurukuta rwumuyoboro, ubugari nuburebure bwikigina bigomba kuba byujuje ibisabwa, hanyuma ukareba niba ubwoko bwa clamp ari bwo.
3. Shira amavuta ku mpeta ya kashe hanyuma urebe niba impeta ya kashe yangiritse.Amavuta yo kwisiga ntashobora gukoreshwa mumavuta.
