Kev txhim kho thiab siv cov cemented carbide pwm

Pwm siv ntau zaus hauv kev tsim khoom. Los ntawm ntau yam xovxwm thiab cov cuab yeej tshwj xeeb ntsia rau ntawm cov xovxwm, cov khoom siv hlau lossis cov hlau tsis yog hlau yog ua rau hauv cov duab uas yuav tsum tau ua. Peb uniformly hu lub cuab tam tshwj xeeb no pwm. Thiab ib qho ua los ntawm cemented carbide raws li cov khoom siv hu ua cemented carbide pwm.

Cov txheej txheem ntawm compression molding muaj keeb kwm ntev, yooj yim heev rau kev khiav lag luam, thiab feem ntau siv hauv kev lag luam. Nws yog tsim rau ntau qhov me me thiab nruab nrab-qhov loj me me nrog cov duab molding yooj yim. Cov txheej txheem ntau lawm ntawm compression molding feem ntau tuaj yeem pom hauv cov chaw tsim khoom cemented carbide. Kev ua haujlwm yooj yim, qib siab ntawm kev siv tshuab, yooj yim kom ua tiav automation, pwm yog cov txheej txheem txheej txheem hauv kev tsim khoom, thiab tseem yog cov cuab yeej tseem ceeb rau kev txhim kho thiab ua tiav cov kev txawj txiav. Piv txwv li, 60% mus rau 80% ntawm cov khoom hauv kev lag luam xws li tsheb, tsheb laij teb, cov khoom siv hluav taws xob, lub cev muaj zog, cov twj paj nruag thiab cov ntsuas, thiab cov khoom siv hluav taws xob yuav tsum tau ua tiav nrog pwm. Ntau cov pwm yog siv los tsim cov khoom lag luam teeb pom kev zoo. Cov khoom txheem xws li cov ntsia hlau, txiv ntseej, thiab cov tshuab ntxhua khaub ncaws tsis tuaj yeem ua rau ntau qhov tsis muaj pwm. Yog li ntawd, txoj kev loj hlob thiab qib ntawm pwm kev txawj ntse ncaj qha cuam tshuam rau kev tsim cov khoom lag luam thiab kuj yog ib qho ntawm cov kev ntsuas ntawm kev ntsuas qib txheej txheem.

Cemented carbide yog sintered carbide ua los ntawm tungsten carbide ua lub ntsiab tivthaiv thiab cobalt raws li lub sij hawm sib txuas. Lub zog dabtsi yog khoov ntawm cemented carbide tuaj yeem ncav cuag 2200 ~ 5100Mpa, thiab nws khaws cov kub tsis kam thiab kub kub hardness ntawm tungsten carbide. Lub hardness ntawm chav tsev kub kuj yog siab heev. Cemented carbide feem ntau yog siv los tsim ntau yam riam, pwm, cov cuab yeej mining thiab hnav-tiv taus qhov chaw. Cemented carbide pwm yeej ib txwm nyiam cov neeg nyiam. Hais lus nruj me ntsis, cemented carbide yog cov khoom siv pwm. Cemented carbide pwm muaj lawv qhov tshwj xeeb corrosion kuj, muaj zog hnav tsis kam, thiab muaj zog ua haujlwm siab.

Cemented carbide pwm feem ntau muaj xws li: txias taub hau tuag, ncab tuag, stamping tuag, kub forging tuag, hlau kos tuag, thiab lwm yam. Cemented carbide txias taub hau tuag yog tuag uas txiav, preform, thiab ua cov dawb paug rau hauv txias-tsim qhov chaw nyob rau hauv txias. taub hau tshuab. Muaj ntau lub fasteners yog ua los ntawm txias taub hau tuag. Lub taub hau txias tuag yog raug rau cov khoom hnyav hnyav, thiab qhov chaw ntawm lawv cov concave tuag yog raug rau siab compressive. Cov khoom siv pwm yuav tsum muaj lub zog siab, toughness thiab hnav tsis kam, thiab carbide txias taub hau pwm ua tau raws li qhov yuav tsum tau ua. Vim txoj kev tsim tshwj xeeb, sab saum toj ntawm lub qhov rais lub cev tseem khaws cov yam ntxwv qub ntawm tungsten carbide, thiab nws qhov hardness yog ze rau pob zeb diamond. Nyob rau tib lub sijhawm, vim tias cobalt siv los ua cov ntawv khi, cov carbide txias taub hau tuag yog cov pwm uas txiav, ua ntej, thiab ua cov ntawv dawb paug rau hauv qhov txias-tsim ntawm lub tshuab txias. Muaj ntau lub fasteners yog ua los ntawm txias taub hau tuag. Lub taub hau txias tuag yog raug rau cov khoom hnyav hnyav, thiab nws qhov chaw tuag yog raug rau siab compressive. Cov khoom siv pwm yuav tsum muaj lub zog siab, toughness thiab hnav tsis kam, thiab carbide txias taub hau tuag ua tau raws li qhov xav tau, thiab nws kuj ua rau nws tawv. Yog li ntawd, carbide txias taub hau tuag cov khoom muaj cov yam ntxwv hauv qab no:

1. Siab hnav tsis kam. Cov khoom siv carbide pwm muaj qhov hnav tsis kam, uas tuaj yeem ua kom ntseeg tau tias lub zog tensile tuaj yeem ua haujlwm tau ntev nyob rau hauv ib qho kev deformation degree thiab xyuas kom meej tias tus qauv qhov loj me tseem tsis hloov.

2. Zoo polishing. Cemented carbide muaj cov khoom zoo polishing thiab tuaj yeem ua tiav rau hauv daim iav tiav qhov tuag kom ntseeg tau tias qhov zoo ntawm cov txheej txheem.

3. Tsawg adhesion rau hlau. Thaum lub caij txias txias, cov khoom siv hlau ferrous muaj qhov adhesion qis rau cov khoom siv cemented carbide, kom ntseeg tau tias cov cemented carbide txias taub hau tuag muaj lub neej ntev.

4. Tsis tshua muaj kev sib txhuam coefficient thiab siv zog tsawg.

5. High thermal conductivity. Vim lub thermal conductivity ntawm cemented carbide tuag cov ntaub ntawv, lub tshav kub generated thaum lub sij hawm txias lub taub hau txheej txheem yuav ua tau sai sai, txhim kho lub durability ntawm tuag.

6. Zoo corrosion kuj.
