Phau Ntawv Qhia Txog HSS Saw Blades: Kev Txiav Kom Tseeb Rau Cov Ntawv Thov Uas Xav Tau Ntau

Kev Nkag Siab Txog Kev Siv HSS: Kev Ua Hlau Uas Ua Rau Qhov Txawv

Cov hniav txiav uas siv High-Speed ​​Steel (HSS) yog ib qho kev nce qib tshiab hauv kev siv tshuab txiav, uas sib xyaw cov hlau sib xyaw nrog cov tungsten (14-18%), molybdenum (5-8%), chromium (3-4.5%), vanadium (1-3%), thiab cobalt (5-10%). Cov zaub mov ua los ntawm cov hlau no ua rau cov hniav txiav tau qhov nyuaj tshwj xeeb ntawm qhov kub tshaj 600°C - qhov zoo tseem ceeb uas cov hniav txiav carbon steel ib txwm yuav lwj sai. Tsis zoo li cov hniav txiav ib txwm, cov HSS variants tswj tau Rockwell Hardness (HRC) ntawm 62-67 txawm tias nyob hauv qhov kub siab heev, txhais tau tias kev txiav tau zoo thaum lub sijhawm ua haujlwm ntev.

Shanghai Easydrill siv cov txheej txheem kho cua sov uas tswj tau zoo los ua kom cov qauv crystalline ntawm lawv cov hniav M2, M35, thiab M42 HSS zoo dua. Txoj kev ua tib zoo no ua kom muaj kev faib tawm ntawm cov hniav sib npaug thaum tswj hwm qhov tawv ntawm lub cev hniav - qhov sib npaug tseem ceeb rau kev tiv thaiv kev puas tsuaj loj heev ntawm cov hniav thaum lub sijhawm txiav ntau.

Cov Kev Zoo ntawm Kev Siv Tshuab Uas Hloov Kev Ua Haujlwm Txiav

1. Kev Tiv Thaiv Kub thiab Kev Ua Haujlwm Hnav Tsis Sib Xws
   Cov hniav HSS ua tau zoo dua cov hniav carbon steel ib txwm muaj 3-5 zaug hauv qhov xwm txheej txiav kub siab. Kev tshawb fawb qhia tau tias thaum txiav ceev nce ntawm 170 hli / feeb mus rau 220 hli / feeb, cov hniav HSS tsuas yog qhia txog kev hnav thawj zaug siab dua 19% piv rau 56% kev hnav ceev hauv cov cuab yeej ib txwm - qhia txog kev ruaj khov thermal zoo dua 1. Qhov no txhais tau tias lub sijhawm ua haujlwm ntev dua thiab txo lub sijhawm tsis ua haujlwm.
2. Kev Zoo Ntawm Qhov Chaw
   Kev sim tshuaj xyuas qhia tau hais tias cov hniav HSS ua kom cov npoo tiav zoo dua (Ra tus nqi) vim lawv muaj peev xwm khaws cov npoo txiav ntse. Thaum cov nqi pub nce ntxiv ntawm 425 hli / feeb mus rau 550 hli / feeb, cov hniav HSS tsuas yog qhia txog qhov nce 10-14% piv rau 25% + hauv lwm txoj hauv kev 1. Qhov no ua rau lawv tsis tseem ceeb rau cov ntawv thov tiav hauv kev tsim khoom hauv aerospace thiab tsheb.
3. Kev Siv Tau Ntau Yam Hauv Cov Khoom Siv
   Qhov sib npaug ntawm qhov nyuaj thiab tawv tshwj xeeb ua rau kev ua cov ntaub ntawv sib txawv zoo:
   • Cov Hlau: Cov hlau sib xyaw (<45 HRC), txhuas, tooj dag, hlau ductile
   • Cov khoom sib xyaw: CFRP, GFRP yam tsis muaj delamination
   • Yas: Acrylics, nylon, thermoplastics muaj zog
   • Ntoo: Cov ntoo tawv, cov laug cam laminated nrog cov fasteners embedded

Kev Ua Hlau & Tshuab
Cov hniav HSS ntawm Shanghai Easydrill yog cov khoom siv tseem ceeb hauv cov chaw ua haujlwm hlau uas ua cov hlau, cov kav dej, thiab cov profile extruded. Lawv cov hniav sib txawv (Triple Chip Grind, Alternate Top Bevel) tiv thaiv kev co harmonic thaum txiav cov kav dej nyias nyias, thaum cov txheej txheem tshwj xeeb xws li TiN ua rau muaj kev nplua nplua hauv kev txiav cov hlau tsis xeb.

Kev Tsim Khoom Tsheb
Cov kab ntau lawm siv cov hniav HSS pulsed-laser welded rau:

• Kev siv tshuab ua cov khoom siv cav (cov hlau nodular castings) 1
• Kev tshem tawm cov iav kis tau tus mob
• Kev tsim cov khoom siv ncua kev kawm
