Hlau daim duab tuag ua tiav stretching thiab shaping los ntawm yas deformation. Thaum cov hlau hlau hla dhau qhov chaw tuag nyob rau hauv lub zog tensile, cov hlau ua rau cov yas deformation vim tias qhov loj me me dua li qhov qub billet loj, ua rau tus ntoo khaub lig me dua -section thiab nce ntev. Qhov chaw ua haujlwm ntawm qhov tuag yog qhov tseem ceeb rau deformation; nws cov duab thiab qhov loj me ncaj qha cuam tshuam rau qib thiab qhov zoo ntawm deformation. Lub sizing cheeb tsam xyuas kom meej tias cov hlau kos tau meej qhov ntev thiab zoo nto zoo.
Lubricant plays lub luag haujlwm hauv kev txo qis kev sib txhuam, txo qis kev kos duab, ua rau lub neej ntev, thiab txhim kho cov khoom nto zoo thaum lub sijhawm teeb duab. Cov ntaub ntawv tuag yog feem ntau nyuaj alloys lossis pob zeb diamond kom tiv taus siab thiab kev sib txhuam. Tuag precision yog qhov tseem ceeb rau cov khoom zoo; siab -precision dies kom ruaj ntseg thiab nto tiav.
Raws li cov qauv kev lag luam, hlau kos duab tuag tuaj yeem muab faib ua ob hom: ib leeg- tuag hlau kos duab thiab ntau- tuag txuas txuas txuas. Ib leeg- tuag hlau daim duab yog tsim rau coarse hlau ua, thaum multi- tuag nruam hlau yog siv rau zoo hlau ntau lawm. Pwm tsim yuav tsum xav txog cov tsis tseem ceeb xws li lub kaum sab xis compression (feem ntau 8-12 degrees) thiab qhov ntev ntawm qhov loj me (kwv yees li 0.8-1.2 npaug ntawm txoj kab uas hla).
Cov teeb meem tshwm sim muaj xws li pwm hnav (kev tshwm sim raws li cov khoom sib txawv ntawm qhov sib txawv los yog khawb ntawm qhov chaw) thiab hlau nplaum rau pwm (ua rau cov khoom tsis zoo). Cov kev daws teeb meem suav nrog kev tshuaj xyuas pwm tsis tu ncua, txhim kho cov txheej txheem lubrication, thiab xaiv cov khoom pwm tsim nyog.
