Kev xyaum siv ntau qhov chaw ntawm tib neeg lub neej. Ntau yam hauv khw yog yooj yim heev. Ua ntej pib ua haujlwm, tus pib yuav tsum kawm txhua yam. Hauv kab lus no, peb yuav tsom mus rau HSS kev xyaum, lawv cov yam ntxwv thiab cov cai xaiv.

Nws yog dab tsi?

HSS, lossis HighSpeedSteel (sawv rau Kev Kub Ceev - kev kub ceev, Hlau - hlau) - cov cim no txhais tau tias cov cuab yeej (laum, kais, milling cutter) yog ua los ntawm cov hlau siab ceev, uas yog qhov tseeb los ntawm lus Askiv txhais lus ntawm cov lus luv. Cov khoom siv tawv tawv ntawm 62 txog 65 HRC . Piv rau cov pa roj carbon siab, qhov no yog cov hlau nyias nyias, tab sis muaj qhov nyuaj dua qhov tseem ceeb. Lub npe siv rau txhua yam ntaub ntawv ntawm pab pawg, tab sis feem ntau nws yog P6M5. Cov hlau muaj qhov nruab nrab tsim khoom, nws tsim nyog rau kev ua haujlwm nrog hlau, cov khoom siv nrog lub zog tsawg dua 900 MPa, kev tsim cov tshuab txiav me me.

Feem ntau ntawm cov hlau ntawm cov pab pawg muaj tungsten - nws qhov kev faib ua feem yog siab heev . Kuj tseem muaj cov pa roj carbon ntau nyob ntawd. Qhov zoo ntawm cov hlau no suav nrog lub zog thiab tus nqi, uas qis dua li cov khoom siv carbide txiav. Ib qho ntxiv, lawv yog cov cuab yeej zoo heev rau kev txiav ib ntus. Qhov tsis zoo yog qhov qis dua ntawm qhov laum thaum piv rau cov cuab yeej carbide.

Cov hlau kub ceev tuaj yeem faib ua hom:

• high-speed high-alloy hlau;
• molybdenum (xaiv M);
• tungsten (qhia los ntawm T).

Cov hom yog tsim los ntawm hom kev sib xyaw tshuaj hauv cov hlau

Tungsten tam sim no siv tsawg dua thiab tsawg dua, vim nws muaj tus nqi siab, thiab tseem yog cov khoom siv tsis tshua muaj. Cov hlau feem ntau siv yog T1 (lub hom phiaj dav hlau) lossis T15, uas muaj cobalt, vanadium. Raws li txoj cai, tom kawg yog siv rau kev ua haujlwm kub thiab ua haujlwm siab.

Los ntawm lub npe nws yog qhov tseeb tias cov ntaub ntawv ntawm M-pawg tau los ntawm cov khoom sib xyaw xws li molybdenum, tib yam lossis ntau tungsten thiab cobalt muaj nyob

Yog li, vanadium thiab carbon ua rau cov hlau txawm tias tiv taus kom hnav sai.

Lawv yog dab tsi?

Laum tuaj ntau yam duab sib txawv. Txhua tus ntawm lawv tau thov hauv ib cheeb tsam tshwj xeeb. Txhua qhov kev xyaum HSS xav tau rau kev txiav hlau.

Muab kauv tsim rau tsim qhov hauv qhov ua los ntawm cov hlau tshwj xeeb, hnav-tiv taus cov hlau, hlau rau cov qauv nrog cov yam ntxwv muaj zog txog 1400 N / mm2, ob qho tib si ib txwm thiab tawv, los ntawm cov xim grey lossis ductile. Nws tau siv ob qho tib si hauv tes tuav cov cuab yeej hluav taws xob thiab pneumatic, thiab hauv cov tshuab txiav hlau.

Kauj ruam laum siv los tsim qhov ntawm cov kab sib txawv hauv cov khoom sib txawv. Cov tsos ntawm cov laum zoo ib yam li lub khob hliav qab nrog cov nplaim dej.

Tub ntxhais laum - lub tog raj kheej hollow, siv los tsim cov qhov hauv cov hlau phom thiab cov hlau tsis muaj hlau. Tshem tawm cov hlau nyob ib ncig ntawm ntug ntawm lub qhov, ua rau cov tub ntxhais tsis khov.

Muaj coob tus diameters, duab, hom.

Npav

HSS Yog lub cim thoob ntiaj teb rau cov hlau siab ceev, HSS Co rau qib cobalt-muaj cov qib. Hlau muaj qhov ntsuas qhov hnyav ntawm 63 txog 67 HRC. Kev tiv thaiv xeb thiab tiv taus cov kua qaub, siv rau cov cuab yeej loj-txoj kab nruab nrab thiab cov txiav txiav, rau txiav cov hlau, tooj liab, tooj dag thiab tooj liab, txhuas thiab nws cov hlau phom.

Yog tias peb nyob ntawm cov cim hauv ntau yam ntxiv, tom qab ntawd muaj cov kev hloov pauv hauv qab no:

• HSS -R - kev ua siab ntev ntawm qhov laum;
• HSS-G - txhais tau tias kev txiav ib feem yog ua tiav nrog cubic boron nitride, ua kom ntev dua ntawm qhov laum;
• HSS-E - hlau nrog ib feem ntawm cobalt, rau cov khoom nyuaj;
• HSS-G TiN - cov cuab yeej nrog lub ntsej muag kho nrog cov tshuaj muaj titanium nitride;
• HSS-G TiAlN - cov cuab yeej coated nrog nitride, txhuas, titanium;
• HSS-E VAP - Laum cim rau txiav stainless hlau.

Cov tuam txhab tsim khoom hauv tsev siv lwm cov cim. Muaj cov tsiaj ntawv M thiab T nyob hauv qab tus lej (piv txwv li, M1).

Cov Lus Qhia Xaiv

Txhawm rau xaiv qhov laum kom raug, koj yuav tsum tau them sai sai rau cov ntsiab lus tseem ceeb

• Kawm cov yam ntxwv ntawm cov khoom thiab muaj peev xwm laum kom ntseeg tau tias lub cuab yeej ua tau raws li qhov xav tau ntawm txoj haujlwm.

• Saib cov xim ntawm cov khoom. Nws tuaj yeem tham txog yuav ua li cas cov hlau tau ua tiav.

  1. xim hlau qhia tau tias tsis muaj kev kho cua sov;
  2. daj - cov hlau tau ua tiav, kev ntxhov siab sab hauv hauv cov khoom raug tshem tawm;
  3. ci kub o tint qhia tias muaj cov titanium nitride, uas ua rau hnav tsis kam;
  4. dub - cov hlau raug kho nrog cov pa kub.
• Txheeb xyuas cov cim kom paub seb hom hlau, txoj kab uas hla, tawv.
• Nrhiav paub txog cov chaw tsim khoom, sab laj nrog cov kws tshaj lij.
• Tshawb xyuas qhov teeb meem ntawm cov cuab yeej ntse.

Laum feem ntau muag hauv cov khoom, piv txwv li nrog cov kab sib txawv. Qhov teeb meem kom tau txais cov cuab yeej zoo li no xav tau kev nkag siab txog lub hom phiaj uas yuav tsum tau siv lub laum thiab yuav siv ntau txoj kev xaiv li cas.

Cov txheej txheem, raws li txoj cai, muaj cov khoom siv nrov thiab tsis tshua muaj neeg siv.
