60Si2Mn intsimbi eshushu eqengqelekayo imivalo engqukuva

I-60Si2Mn spring steel yintsimbi yasentwasahlobo ye-silico-manganese enamandla angaphezulu kancinci, ukuqina kunye nokuqina kune-55Si2Mn. I-60Si2Mn imveliso yentsimbi yasentwasahlobo ivelisa imithombo ethe tyaba enomthwalo omkhulu okanye imithombo yekhoyili enobubanzi obungaphantsi kwe-30mm. Ikwalungele ukwenza imithombo ekwaziyo ukumelana nobushushu kunye nendawo engonakalisiyo kunye nobushushu obusebenzayo obungaphantsi kwe-250 °C kunye nomthwalo otshintshanayo kunye noxinzelelo oluphezulu. Imithombo emikhulu yekhoyili ebalulekileyo yokusebenza phantsi, kunye neenkqubo zokufunxa ukothuka kweemoto.

Icandelo leMichiza:

Iimpawu zoomatshini:

Amandla okuqina σb (MPa): ≥ 1274 (130)
Amandla esivuno σs (MPa): ≥1176 (120)
Ubude δ10 (%): ≥5
Ukuncipha kwendawo ψ (%): ≥25
Ubunzima: ukuqengqeleka okushushu, ≤321HB; umzobo obandayo + unyango lobushushu, ≤321HB

Iinkcukacha zobushushu:

Inkcazo yonyango lwe-60Si2Mn: ukucima i-870 °C ± 20 ° C, ukupholisa ioli; ubushushu 480 ° C ± 50 ° C (ifuneka ngokukodwa, ± 30 ° C).
Umbutho we-Metallographic: i-troostite enomsindo.

Ubume bokuhambisa: Intsimbi eshushu ihanjiswa kwimeko yokushisa okanye engabonakaliyo, kunye nentsimbi epholileyo ihanjiswa kwimeko yokushisa.
Iimpawu zonikezelo ezishushu eziqengqelekayo: 2.0 ~ 18.0mm, kunye kunye nangaphandle kwe-annealing. Iimpawu zokuhanjiswa okubandayo: 0.3 ~ 4.3mm (umcu wentsimbi)

Indlela yokunyanga ubushushu

Iindlela zokunyanga ubushushu be-60Si2Mn yi-isothermal tempering kunye nokulinganisa ukucima, ukucima ubushushu obuphantsi kunye nobushushu obuphezulu, inkqubo yonyango lobushushu. Indlela inokuphucula ngokufanelekileyo amandla kunye nobomi benkonzo ye-60Si2Mn spring steel. I-60Si2Mn yeyentsimbi yasentwasahlobo, ilungele ukwenza intwasahlobo yamagqabi emoto. I-60Si2Mn yonyango lobushushu lwentsimbi yasentwasahlobo ye-isothermal kunye nokucima ukulinganisa, ukucima ubushushu obuphantsi kunye nobushushu obuphezulu, inkqubo yonyango lobushushu. Indlela inokuphucula ngokufanelekileyo amandla kunye nobomi benkonzo ye-60Si2Mn spring steel.

ukuxinana

Ubuninzi be-60Si2Mn be-7.85g / cm3. I-60Si2Mn isetyenziswa ngokubanzi i-silicon manganese spring steel, amandla, ukuqina kunye nokuqina kune-55Si2Mn phezulu kancinci. Ilungele izithuthi zikaloliwe, ishishini letrektara yeemoto ukuvelisa umthwalo omkhulu wemithombo ethe tyaba okanye ucingo lwedayamitha eyi-30mm ngaphantsi kwe-coil spring.
