Muaj ntau hom tshuab shear siv los ntawm dov rhiav. Raws li cov duab thiab kev teeb tsa ntawm cov hniav ntawm cov txiab thiab cov duab ntawm cov dov qhov chaw, lub tshuab shear tuaj yeem muab faib ua: sib npaug ntawm cov hniav shear shear, kab pheeb ces kaum shear, thiab discoscopic txiab thiab txhua yam ntawm ya txiab.
Ob lub ntsej muag ntawm cov hniav sib tsoo tshuab yog sib npaug rau ib leeg, uas yog tus cwj pwm los ntawm ob qho kev txiav hniav sib txuas nrog cov hlau txiav hlau tib lub sijhawm. Cov txheej txheem shear tiav ib zaug nyob rau hauv ib lub sij hawm luv luv, lub shear efficiency siab, thiab lub shear yog loj. Feem ntau siv rau kab rov tav thermal shear thawj dov billets (square, phaj dawb paug) thiab lwm yam squares thiab rectangular seem.
Ob lub ntsej muag ntawm lub tshuab txiav tshuab muaj lub kaum ntse ntse. Feem ntau, cov hniav yog tilted thiab cov hniav qis yog kab rov tav. Xws li cov tshuab shear feem ntau yog siv rau txias-txiav thiab kub-txiav steel daim hlau, steel siv, nyias daim hlau, thiab welded yeeb nkab billets, thiab qee zaum siv los txiav cov hlau me me.
Cov hniav ntawm lub discoscopic shear tshuab yog tsim rau hauv ib lub disc, thiab muaj ob hom discs siv nyob rau hauv lub steel dov rhiav: ib hom rau longitudinal shear rau steel daim hlau thiab hlau; Essence Lawv cov yam ntxwv zoo sib xws yog ua kom tiav cov haujlwm shear los ntawm kev sib hloov cov khub khub -pair -pair -pair -cut blades.
Flying txiab feem ntau yog siv rau dov qhov chaw ntawm kab rov tav shear motion. Flying txiab yog siv nyob rau hauv hom steel ntau lawm, billet ntau lawm thiab steel phaj ntau lawm. Lub ntsiab lus ntawm kev ya davhlau yog ua kom tiav cov haujlwm shear thaum lub sijhawm ua haujlwm ntawm cov hlau, yog li kev khiav hauj lwm ceev ntawm cov hlau yuav tsum tau roughly tib yam li cov hniav txiav. Feem ntau ntawm cov tshuab shear no yog teem rau ntawm txoj kab kev ua haujlwm ntawm semi-nruab nrab lossis txuas ntxiv dov tshuab.
Tsis ntev los no, txhawm rau daws qhov teeb meem ntawm kev thauj khoom loj ntawm cov hniav txiav, ib kauj ruam -by -step shear tshuab tau tshwm sim. Cov yam ntxwv ntawm hom txiab no yog nyob rau hauv ntu hauv cov txheej txheem shear. Ntau yam ntawm cov tshuab txiav tau hais ua ntej yog eccentric axis lossis tsawg dua ib lub voj voog kom tiav cov shear txav, thiab cov kauj ruam-type shear tshuab yog ib tug xov tooj ntawm eccentric axes kom tiav cov shear txiav. Tus nqi eccentric ntawm eccentric axis ntawm cov kauj ruam-hom shear tshuab yog tsawg dua (feem ntau yog 5-10mm). Cov kauj ruam-type shear tshuab siv cov txheej txheem ntawm cov kauj ruam mus txuas ntxiv hloov txoj hauj lwm ntawm riam rooj kom tiav tag nrho cov txheej txheem shear.
