Iyo isina musono simbi inogadzira chubhu inosuma muchidimbu iyo chaiyo class uye basa rekabhoni simbi chubhu.

1. General kabhoni simbi chubhu

Kazhinji, simbi ine carbon content ye ≤0.25% inonzi low-carbon steel. Iyo annealed structure ye low-carbon steel is ferrite uye shoma shoma ye pearlite. Iyo ine yakaderera simba uye kuoma, yakanaka plastiki uye kuoma, uye iri nyore kudhirowa, chitambi, extrude, Forging uye welding, pakati peiyo 20Cr simbi inoshandiswa zvakanyanya. Simbi ine rimwe simba. Mushure mekudzima uye kudziya pakudziya kwakadzikira, simbi iyi ine yakanaka yakazara mechanicha zvimiro, yakanaka yakaderera-tembiricha inokanganisa kuoma, uye brittleness haisi pachena.

Zvishandiso:Muindasitiri yekugadzira michina, inokodzera kugadzira welded zvimiro zvikamu uye zvikamu zvisiri pasi pekunetseka kwakanyanya mushure mekugadzira, kupisa stamping uye machining. Mumagetsi ekugadzira turbine uye bhailer yekugadzira maindasitiri, inonyanya kushandiswa kune mapaipi, flanges, nezvimwe zvinoshanda mune zvisiri zvinoodza media. Headers uye zvakasiyana-siyana fasteners; zvakare inokodzera kugadzirwa kwezvidiki uye zvepakati-saizi carburizing uye carbonitriding zvikamu mumotokari, matirakita uye akajairwa muchina kugadzira, senge bhutsu dzemaoko, lever shafts, uye gearbox yekumhanyisa maforogo pamotokari, transmission passive giya uye camshafts pamatirakita, suspension balancer. shafts, mukati uye kunze mabhushi ezviyereso, nezvimwewo; mukugadzirwa kwemichina inorema uye yepakati, senge akaumbwa kana akatsikirirwa tambo dzetii, cheni, levers, maoko, zvigadziriso, nezvimwe.

2. Low carbon steel chubhu
Yakaderera-kabhoni simbi: Yakaderera-kabhoni simbi ine kabhoni inodarika 0.15% inoshandiswa kune shafts, bushings, sprockets, uye mamwe epurasitiki molds ayo anoda kuomarara kwakanyanya uye kwakanaka kupfeka kusagadzikana pamusoro peiyo carburizing uye kudzima uye kuderera-kupisa. Chikamu. Mushure mekuputira uye kudzima uye kudzika-tembiricha, iyo yakaderera-kabhoni simbi ine chimiro chepamusoro-kabhoni martensite pamusoro uye yakaderera-kabhoni martensite pakati, kuitira kuti ive nechokwadi chekuti nzvimbo ine kuoma kwakanyanya uye yakakwirira kupfeka kuramba uku. nzvimbo yacho ine kuoma kwakanyanya. Simba rakanaka uye kuoma. Yakakodzera kugadzira bhureki remaoko shangu, lever shafts, gearbox kumhanya maforogo, transmission passive giya, camshafts pamatirakita, suspension balancer shafts, mukati nekunze mabhuranzi emabharanzi, maoko, zvigadziriso nezvimwe zvikamu.

3. Medium carbon steel chubhu
Simbi yepakati-kabhoni: Carbon simbi ine kabhoni yemukati ye0.25% kusvika 0.60%. 30, 35, 40, 45, 50, 55 uye mamwe mamakisi ndeepakati-kabhoni simbi. Nokuti pearlite yemukati musimbi inowedzera, simba rayo uye kuoma kwakakwirira kudarika kare. Kuoma kunogona kuwedzera zvakanyanya mushure mekudzima. Pakati pavo, 45 simbi ndiyo inonyanya kufanana. 45 simbi isimbi yakakwirira-yepakati-kabhoni yakadzimwa uye yakanyoroveswa simbi, ine imwe plastiki uye kuoma, uye kuita kwakanaka kwekucheka. Inogona kuwana yakanaka yakazara mechanicha zvivakwa nekudzima uye nekudziya kurapwa, asi kuomarara kwayo hakuna kunaka. Inoshandiswa kugadzira zvikamu zvine simba repamusoro zvinodiwa uye kuoma kwepakati. Inowanzo shandiswa mukudzimwa uye kushatirwa kana kujaira. Kuti iite kuti simbi ive nekusimba kwakakosha uye kubvisa kushushikana kwayo kwasara, simbi inofanira kudzimwa uye yobva yanyungudutswa kuita sorbite.
