Tungsten Carbide Hlau Drawing Tuag

Hlau kos tuag yog qhov tseem ceeb tshaj plaws ntawm kev lag luam hlau kos duab. Thiab rau kev tsim cov hlau zoo ntawm tus nqi qis tshaj thiab tons ntawm cov xaim, cov hlau kos duab tuag yuav tsum ua kom zoo. Kev xaiv tsis raug thiab tsis zoo ntawm cov tuag ntxiv tsis yog tsuas yog rau cov nqi tuag ncaj qha xwb tab sis kuj yuav tsim cov hlau tsis zoo, tsis muaj qhov tseeb, thiab cov khoom siv hlau tsis zoo nrog rau lub tshuab ua haujlwm ntev, thiab ua rau poob ntawm kev tsim khoom. Yog li nws tau hais tias kev tsim cov hlau thiab kev tuag yog ib txwm muaj kev sib koom tes rau kev ua tau zoo. Kab lus no yuav tsuas tham txog qhov tseem ceeb ntawm tungsten carbide hlau kos duab tuag.

Ntau cov ntaub ntawv muaj nyob rau hauv kev tsim cov hlau kos duab tuag, suav nrog tungsten carbide, pob zeb diamond, hluavtaws pob zeb diamond, PCD, thiab lwm yam. Txhua tus ntawm lawv muaj ntau yam kev siv. Yuav luag tag nrho cov hlau yog tag nrho los yog tsawg kawg yog ib feem, los ntawm cov hlua hlau mus rau ib qho me me nyob ntawm cov khoom siv thiab qhov xav tau qhov tseeb, los ntawm tungsten carbide tuag vim lawv lub cev thiab cov nqi siv tau zoo.

Tungsten carbide tuag muaj siab hardness ob qho tib si nyob rau hauv chav tsev kub thiab siab kub tau ntsib nyob rau hauv kev kos duab. Raws li tungsten carbide nibs yog tsim los ntawm cov hmoov metallurgy txoj kev thiab yog ua los ntawm tungsten carbide. Tungsten carbide nibs tuaj yeem ua rau ntau qib. Cov qib sib txawv ntawm tungsten carbide hlau kos duab tuag muaj qhov sib txawv hardness, xws li 1400 txog 2000 HV.

Tungsten carbide dies muaj siab tiv thaiv deformation nyob rau hauv load thiab muaj ib tug me me thermal coefficient ntawm expansion. Yog li ntawd, qhov sib txawv ntawm qhov loj ntawm qhov tuag vim qhov kub thiab txias ua haujlwm yog tsawg heev. Txawm hais tias PCD hlau kos duab tuag yuav muaj kev ua tau zoo dua li tungsten carbide hlau kos duab tuag, tungsten carbide hlau kos duab tuag yog pheej yig dua thiab tus nqi ntau dua.

Rau kev kos duab hlau, cov nibs yuav tsum muaj zog hnav tsis kam thiab tawv kom tiv taus deformation nyob rau hauv load. Txij li thaum lub hardness thiab toughness ntawm ib yam khoom yog inversely proportional, ib tug optimum ua ke ntawm ob lub zog raws li ib daim ntawv thov yuav tsum tau. Dab tsi ntxiv, lub zog hloov pauv hloov ntawm tungsten carbide hlau kos duab tuag tuaj yeem yog 1700 txog 2800 N / mm2, uas tam sim no tsim rau kev kos duab. Cov qib sib txawv tau txais los ntawm qhov sib txawv ntawm cov nplej loj ntawm tungsten carbide thiab cobalt feem pua.

Piv txwv li, hlau kos duab tuag tuaj yeem ua rau cov khoom sib txawv, txawm li cas los xij, qhov nrov tshaj plaws yog tungsten carbide hlau kos duab tuag, vim tias lawv raug nqi ntau thiab muaj kev ua tau zoo.
