Nyob rau hauv txoj kev loj hlob sai ntawm kev lag luam tsheb, qhov kev thov rau cov log tsheb yog hloov mus rau flattening, kev kub ceev thiab kev tiv thaiv ib puag ncig, uas sib haum rau cov kev xav tau siab rau cov log tsheb pwm. Cov tsos thiab kev ua tau zoo ntawm lub log tsheb feem ntau yog nyob ntawm qhov zoo ntawm cov txheej txheem vulcanization, thiab cov pwm, uas yog cov cuab yeej tseem ceeb hauv cov txheej txheem vulcanization, muaj kev cuam tshuam ncaj qha rau qhov zoo ntawm lub log vim nws cov qauv tsim nyog.
Kev tsim ntawm ob lub halves ntawm lub log pwm yog qhov yooj yim, feem ntau muaj cov phaj sab sauv thiab sab qis thiab sab sauv thiab qis steel rims. Qhov seem ntawm sab phaj yog nyob rau ntawm kab nruab nrab ntawm cov qauv, thiab cov pwm yuav qhib raws kab no thaum ua haujlwm. Nyob rau hauv sib piv, cov qauv ntawm cov active pwm yog ntau nyuaj, nrog rau cov kab noj hniav phaj thiab cov pwm plhaub. Lub phaj kab noj hniav ncaj qha hu rau lub log tsheb dawb thiab yog tsim los ntawm cov qauv thaiv, sab phaj thiab steel rims; lub plhaub pwm ua haujlwm raws li cov txheej txheem qhia, xws li lub tes tsho nruab nrab pwm, lub rooj zaum hneev, lub hau npog, thiab lwm yam, los tswj qhov qhib thiab kaw txav ntawm pwm. Ntawm lawv, lub rooj zaum hneev nti thiab cov qauv thaiv txav radially.
Daim ntawv qhia nto ntawm conical nto active pwm yog conical. Piv nrog rau lub dav hlau inclined pwm, nws muaj kev ua tau zoo dua. Cov cuab yeej siv tshuab ib txwm tuaj yeem ua tau raws li qhov yuav tsum tau ua. Kev sib dhos precision yog tsawg. Tom qab hnav, nws tuaj yeem them rov qab rau qhov sib txawv ntawm lub voj voog. Nws muaj kev cuam tshuam me ntsis rau lub voj voog ntawm lub log, thiab cov roj hmab ntug thiab cov teeb meem misalignment tsis yog qhov tseem ceeb. Txawm li cas los xij, thaum lub sij hawm qhib thiab kaw cov pwm, cov phaj hnav-tiv taus hnav tsis sib xws, uas tuaj yeem cuam tshuam qhov smoothness ntawm kev txav thiab kev hloov pauv ntawm vulcanizer.
Kev ua kom zoo ntawm cov log tsheb pwm thiab kev nce qib ntawm thev naus laus zis tsis yog tsuas yog cuam tshuam cov kev xav tau ntawm kev lag luam tsheb, tab sis kuj txhawb kev txhim kho cov log tsheb tsim tshuab. Txawm hais tias nws yog ib qho yooj yim thiab yooj yim-rau-ua haujlwm log tsheb ib nrab pwm los yog cov pwm ua haujlwm nrog cov kev taw qhia siab, nws muab kev txhawb nqa tseem ceeb rau kev tsim cov log tsheb zoo. Rau cov pwm nquag, txawm tias nws yog lub dav hlau inclined lossis conical nto, nws cov qauv tsim thiab kev hloov kho kom zoo yog los xyuas kom meej qhov ua tau zoo ntawm lub log tsheb thaum lub sij hawm vulcanization txheej txheem.
