Ndeapi maitiro emidziyo yekucheka carbide?
Maturusi eCarbide, kunyanya anoverengeka carbide maturusi, ndiwo anotungamira ezvigadzirwa zve CNC machining tools. Kubva kuma1980s, akasiyana-siyana akasimba uye ane indexable carbide maturusi, kana kuisa, akawedzera kune akasiyana siyana ekugadzirisa. Zvishandiso, shandisa indexable carbide maturusi ekuwedzera kubva kune akareruka maturusi uye kumeso ekuchekesa kucheka kusvika kune chaiyo, yakaoma, uye yekugadzira maturusi. Saka, ndeapi maitiro emidziyo yecarbide?
1. Kuomarara kwakanyanya: Maturusi ekucheka ecarbide anogadzirwa necarbide ine kuoma kwakanyanya uye nzvimbo yekunyungudika (inonzi hard phase) nesimbi binder (inonzi bonding phase) nenzira yepowder metallurgy, uye kuoma kwayo i89~93HRA, Kukwirira kudarika kuya high-speed simbi, pa5400C, kuoma kuchiri kukwanisa kusvika 82-87HRA, iyo yakafanana neyesimbi yepamusoro-soro pakupisa kwekamuri (83-86HRA). Kuomarara kwecemented carbide kunosiyana nehunhu, huwandu, saizi yezviyo uye zviri mukati mesimbi inosunga chikamu, uye kazhinji inodzikira nekuwedzera kwesimbi inosunga chikamu chemukati. Iine yakafanana inonamira chikamu chemukati, kuoma kweYT alloy kwakakwira kupfuura iyo yeYG alloy, nepo alloy ine TaC (NbC) ine yakanyanya kuoma pakupisa kwakanyanya.
2. Kupeta kusimba uye kusimba: Simba rekukotama reyakajairwa simende carbide iri muchikamu che900-1500MPa. Iyo yakakwirira yemukati yesimbi inosunga chikamu, iyo inokwidza simba rekukombama. Kana iyo binder yemukati yakafanana, YG(WC-Co). Simba reiyo alloy rakakwira kupfuura iro reYT (WC-Tic-Co) alloy, uye simba rinodzikira nekuwedzera kweTiC yemukati. Cemented carbide chinhu chine brittle, uye kusimba kwayo patembiricha yekamuri inongova 1/30 kusvika 1/8 yeHSS.
3. Kuramba kwakanaka kupfeka. Iko kumhanya kwekucheka kwematurusi e-cemented carbide ndeye 4 ~ 7 nguva yakakwirira kupfuura yesimbi inomhanya, uye hupenyu hwematurusi hwakareba 5 ~ 80 nguva. Pakugadzira mold uye maturusi ekuyeresa, hupenyu hwesevhisi hwakareba 20 kusvika 150 nguva kupfuura iyo yealloy tool simbi. Inogona kucheka zvinhu zvakaoma kusvika makumi mashanu HRC.
Kushandiswa kwemidziyo yecarbide: maturusi ecarbide anowanzo shandiswa muCNC machining nzvimbo, CNC yekuchera michina. Inogona zvakare kuisirwa pamushini wakajairwa wekugaya kuti ugadzirise zvimwe zvakaoma, zvisina kuomesesa zvinopisa zvinopisa.
Parizvino, maturusi ekugadzirisa ezvigadzirwa zvecomposite, mapurasitiki eindasitiri, plexiglass zvinhu uye zvisiri-ferrous simbi zvinhu pamusika ese maturusi ecarbide, ane hunhu hwekuoma kwepamusoro, kusapfeka kwekusagadzikana, kusimba kwakanaka, kushomeka kwekupisa uye kushora. Zvakare nhevedzano yezvivakwa zvakanakisa, kunyanya kuomarara kwayo kwakanyanya uye kusapfeka, kunyangwe ikaramba isina kuchinjika pakudziya kwe500 ° C, ichiri nekuoma kwakanyanya pa1000 ° C.
Carbide inoshandiswa zvakanyanya sematurusi emidziyo, senge maturusi ekuchekeresa, zvigayo, mapurani, madhiri, maturusi anobhowa, nezvimwewo, kucheka simbi, non-ferrous metal, mapurasitiki, chemical fibers, graphite, glass, stone, etc. Zvakajairwa. simbi inogonawo kushandiswa kucheka simbi isingadziviriri, simbi isina tsvina, yakakwira manganese simbi, simbi yekushandisa uye zvimwe zvakaoma-ku-muchina zvinhu.
