Icyuma kizunguruka
Ibyuma bizunguruka bivuga umurongo ukomeye wibyuma hamwe nu gice cyizengurutse.Ibisobanuro byayo bigaragazwa na diametre, muri milimetero (mm), nka "50mm" bisobanura ibyuma bizengurutse bifite diameter ya mm 50.
Icyuma kizengurutse kigabanijwemo ubwoko butatu: buzungurutse, bushyushye kandi bukonje.Ibisobanuro byibyuma bishyushye bizunguruka ni mm 5.5-250.Muri byo: 5.5-25 mm ntoya ntoya izengurutswe ahanini itangwa mumigozi yimigozi igororotse, ikunze gukoreshwa nkibyuma, ibyuma nibice bitandukanye bya mashini;ibyuma bizunguruka birenze mm 25 bikoreshwa cyane cyane mugukora ibice byubukanishi hamwe nu miyoboro ya tube idafite ibyuma bitegereje.
Itondekanya umurongo
1.Gutondekanya ukurikije imiti
Ibyuma bya karubone birashobora kugabanywamo ibyuma bike bya karubone, ibyuma bya karubone yo hagati hamwe nicyuma kinini cya karubone ukurikije imiti (ni ukuvuga ibirimo karubone).
(1) Icyuma cyoroheje
Bizwi kandi nk'ibyuma byoroheje, ibirimo karubone biva kuri 0,10% kugeza 0.30%.Icyuma gike cya karubone cyoroshye kwemera gutunganywa bitandukanye nko guhimba, gusudira no gukata, kandi akenshi bikoreshwa mugukora iminyururu, imirongo, imigozi, ibiti, nibindi.
(2) Icyuma giciriritse
Ibyuma bya karubone birimo karubone ya 0,25% kugeza 0.60%.Hano hari ibyuma byiciwe, ibyuma byica igice, ibyuma bitetse nibindi bicuruzwa.Usibye karubone, irashobora kandi kuba irimo manganese nkeya (0,70% kugeza kuri 1,20%).Ukurikije ubuziranenge bwibicuruzwa, bigabanijwemo ibyuma bisanzwe byubatswe byubatswe nicyuma cyiza cya karubone.Gutunganya neza ubushyuhe no kugabanya imikorere, imikorere mibi yo gusudira.Imbaraga nubukomezi biruta ibyuma bya karubone nkeya, ariko plastike nubukomezi biri munsi yicyuma gito cya karubone.Ibikoresho bishyushye kandi bikonje bikonje birashobora gukoreshwa bitabaye ibyo kuvura ubushyuhe, cyangwa nyuma yo kuvura ubushyuhe.Icyuma giciriritse giciriritse nyuma yo kuzimya no gutwarwa bifite imiterere myiza yubukanishi.Gukomera cyane gushobora kugerwaho ni nka HRC55 (HB538), naho σb ni 600-1100MPa.Kubwibyo, muburyo butandukanye bwo gukoresha imbaraga ziciriritse, ibyuma bya karubone yo hagati nibyo bikoreshwa cyane.Usibye gukoreshwa nk'ibikoresho byo kubaka, ikoreshwa cyane mu gukora ibice bitandukanye bya mashini.
(3) Icyuma kinini cya karubone
Akenshi bita ibyuma, ibikoresho bya karubone biva kuri 0,60% kugeza kuri 1.70%, kandi birashobora gukomera no gutwarwa.Inyundo, inkongoro, nibindi bikozwe mubyuma birimo karubone ya 0,75%;ibikoresho byo gukata nka myitozo, kanda, reamers, nibindi bikozwe mubyuma birimo karubone ya 0,90% kugeza 1.00%.
2.Bishyizwe hamwe nubwiza bwibyuma
Ukurikije ubwiza bwibyuma, birashobora kugabanywamo ibyuma bisanzwe bya karubone nicyuma cyiza cya karubone.
.Mu Bushinwa no mu bihugu bimwe na bimwe, igabanijwemo ibyiciro bitatu ukurikije uburyo bwo gutanga ibicuruzwa: Icyiciro cya A (Icyiciro cya A A) ni ibyuma bifite ibikoresho byemewe.Icyiciro cya B Icyiciro (Icyiciro B icyiciro) nicyuma gifite imiti yemewe.Icyuma kidasanzwe (C ubwoko bwicyuma) nicyuma cyemeza imiterere yubukanishi hamwe nibigize imiti, kandi akenshi bikoreshwa mugukora ibice byingenzi byubatswe.Muri iki gihe Ubushinwa bukora kandi bugakoresha ibyuma bya A3 byinshi (Icyiciro A No 3 ibyuma) bifite karubone igera kuri 0,20%, ikoreshwa cyane cyane mubikorwa byubwubatsi.
Ibyuma bimwe na bimwe byubaka karubone byongeramo urugero rwa aluminium cyangwa niobium (cyangwa ibindi bintu bigize karbide) kugirango bibe nitide cyangwa ibice bya karbide kugirango bigabanye gukura kwimbuto.Ushaka ubumenyi bwinshi bwa CNC, shakisha konte rusange "NC programming teaching" kuri WeChat, Komeza ibyuma kandi ubike ibyuma.Mu Bushinwa no mu bihugu bimwe na bimwe, kugira ngo huzuzwe ibisabwa byihariye by’ibyuma by’umwuga, imiterere y’imiti n’imiterere y’ibyuma bisanzwe byubatswe byahinduwe, bityo biteza imbere urukurikirane rw’ibyuma by’umwuga by’ibyuma bisanzwe byubatswe (nk'ikiraro, inyubako, Ibyuma, ibyuma byumuvuduko, nibindi).
.Ukurikije ibintu bitandukanye bya karubone n'imikoreshereze, ubu bwoko bw'ibyuma bushobora kugabanywamo ibice bitatu:
① munsi ya 0.25% C ni ibyuma bya karubone nkeya, cyane cyane 08F na 08Al hamwe na karubone iri munsi ya 0,10%, ikoreshwa cyane nkibice bishushanya cyane nk'imodoka n'amabati kubera gukurura kwimbitse no gusudira …… gutegereza .20G nibikoresho byingenzi byo gukora amashyiga asanzwe.Byongeye kandi, ibyuma bike bya karubone nabyo bikoreshwa cyane nka carburizing ibyuma byo gukora imashini.
②0.25 ～ 0,60% C nicyuma giciriritse giciriritse, gikoreshwa cyane muri leta yazimye kandi ifite ubushyuhe kugirango ikore ibice munganda zikora imashini.
Kurenga 0,6% C nicyuma kinini cya karubone, gikoreshwa cyane mugukora amasoko, ibikoresho, imizingo, nibindi. Ukurikije ibirungo bitandukanye bya manganese, birashobora kugabanywamo amatsinda abiri yibyuma birimo manganese isanzwe (0.25-0.8 %) n'ibirimo byinshi bya manganese (0.7-1.0% na 0.9-1.2%).Manganese irashobora kunoza ubukana bwibyuma, igashimangira ferrite, kandi ikongerera imbaraga umusaruro, imbaraga zingana no kwambara ibyuma.Mubisanzwe, ikimenyetso "Mn" cyongeweho nyuma yicyiciro cyibyuma birimo manganese nyinshi, nka 15Mn na 20Mn, kugirango bitandukane nicyuma cya karubone hamwe nibisanzwe bya manganese.
3.Gutondekanya intego
Ukurikije porogaramu, irashobora kugabanywamo ibyuma byubaka ibyuma bya karubone nicyuma cya karubone.
Ibikoresho bya karubone Ibyuma bya karubone biri hagati ya 0,65 na 1.35%.Nyuma yo kuvura ubushyuhe, gukomera no kwihanganira kwambara birashobora kuboneka.Ikoreshwa cyane mugukora ibikoresho bitandukanye, ibikoresho byo gukata, ibishushanyo nibikoresho byo gupima (reba ibyuma byabikoresho).
Ibyuma byubatswe bya karubone bigabanijwemo amanota 5 ukurikije umusaruro wibyuma:
Q195, Q215, Q235, Q255, Q275
Buri kirango kigabanijwemo amanota A, B, C, na D bitewe nubwiza butandukanye.Hariho ubwoko bune cyane, kandi bumwe bufite bumwe gusa;hiyongereyeho, hari itandukaniro muburyo bwa deoxidation yo gushonga ibyuma.
Ikimenyetso cyuburyo bwa Deoxygenation:
F - ibyuma bitetse
b —— ibyuma byiciwe igice
Z —— yishe ibyuma
TZ —— ibyuma byishe bidasanzwe
Ibikoresho by'ibyuma bizunguruka: Q195, Q235, 10 #, 20 #, 35 #, 45 #, Q215, Q235, Q345, 12Cr1Mov, 15CrMo, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65Mn , 50Mn, 50Cr, 3Cr2W8V, 20CrMnTi, 5CrMnMo, n'ibindi.
