Qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem hlau shearing

Puas yog shear haum rau txiav cov duab yooj yim?

Rau kev txiav cov hlau yooj yim, cov txheej txheem hlau shearing yog ib qho kev xaiv zoo nkauj heev. Nws sai sai no. Nws' yooj yim. Nws's pheej yig.

Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab txog qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem hlau shearing - lossis ib qho kev txiav hlau uas koj xav tau - kom koj tuaj yeem ntsuas seb nws haum rau koj cov kev xav tau thiab qhov tseem ceeb.

Ua haujlwm rau cov duab yooj yim - tab sis tsis tas li

Feem ntau, shearing yuav tsum tau siv lub zog rau cov hniav txav thiab thawb lub workpiece tawm tsam cov hniav nyob ruaj ruaj. Cov txheej txheem hlau shearing no (tseem hu ua kev txiav tuag lossis ntau tus swb) yuav yog qhov zoo tagnrho rau kev txiav cov khoom yooj yim thiab pheej yig.

Piv txwv li, piv txwv li, koj xav txiav ib lub pob khawm yooj yim los ntawm cov khoom uas muaj cov pa roj carbon tsawg (piv txwv li, tsis muaj stainless) hlau hlau nrog ib txoj kab uas hla ntawm 0.060" (1.5 hli). Cov txheej txheem hlau shearing tuaj yeem muab qhov luv luv ntawm cov coils txuas ntxiv, yog li ua rau koj tus nqi qis dua li lwm txoj hauv kev. Vim tias tsis muaj kev pheej hmoo ntawm kev tawg thaum txiav hlau, shearing tuaj yeem ua haujlwm ntev li ntev tau qee qhov ntawm deformation tau txais.

Ntawm qhov tod tes, xav tias koj xav tau extruded tuab-walled tubing rau cov kav dej, HVAC systems, thiab lwm yam kav dej. Ntawm no, cov cuab yeej txiav hlau tuaj yeem ua rau puas tsuaj rau cov txheej txheem ntawm extrusion, ua rau kev txiav tsis zoo.

Qhov zoo ntawm cov txheej txheem hlau shearing

Shear ua txoj kab ncaj nraim tsis tsim cov chips lossis hlawv lossis melting khoom. Qhov no tso cai rau cov txheej txheem ua haujlwm tau zoo nrog cov hlau softer xws li txhuas, tooj dag, tooj liab thiab cov pa roj carbon tsawg.

Cov txheej txheem hlau shear tuaj yeem siv nrog yuav luag txhua txoj kab uas hla thiab tshwj xeeb tshaj yog tus nqi zoo rau kev ua haujlwm siab uas tsim ntau txhiab daim ib teev. Nyob rau hauv ib lub hlau shearer, cov hniav tuaj yeem ntsia tau rau ntawm lub kaum sab xis kom txo cov shear quab yuam uas yuav tsum tau ua kom muaj kev txiav tawm.

Tej zaum qhov zoo tshaj plaws ntawm shearing yog tias nws tsim tsawg los yog tsis muaj slit thiab yuav luag tsis muaj khoom poob. Rau cov ntawv thov xws li shear tuav, qhov kam rau ua yog ± 0.005 (0.127 mm).

Tseem ceeb qhov tsis zoo ntawm shearing

Txawm hais tias" qhov zoo", cov txheej txheem hlau shearing muaj qee qhov tsis zoo.

Rau cov hlau hnyav dua, shear tsis zoo tagnrho. Piv txwv li, cov txheej txheem ntawm kev txiav tungsten tsuas yog lub tswv yim tsis zoo. Vim tias tungsten nyuaj heev thiab feem ntau ua nkig, qhov no tuaj yeem ua rau ib nrab delamination lossis tawg ntawm tungsten, nrog rau qhov tseem ceeb ntawm cov cuab yeej nws tus kheej.

Txawm hais tias cov txheej txheem hlau shear tuaj yeem siv tau rau ntau qhov sib txawv thiab feem ntau raug nqi rau kev ua haujlwm loj, nws tsis zoo tagnrho rau shear lengths tsawg dua 0.125" (3.175 hli).

Tsis tas li ntawd, hlau shearing tsis tuaj yeem suav tias yog burr dawb txiav. Qhov no yog vim lub zog shear nws tus kheej feem ntau tsim burrs thiab kawg deformations. Yog li ntawd, shearing tej zaum yuav tsis yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau ntxuav lub ntsej muag kawg.

Tus nqi ntawm deformation tshwm sim thaum lub hlau txiav tsis yog nyob ntawm qhov quab yuam uas cov hniav tsoo lub workpiece. Nws kuj nyob ntawm thaj chaw tshem tawm lossis qhov kev ncua deb ntawm cov hniav. Clearance feem ntau yog 5% mus rau 40% ntawm tag nrho cov thickness ntawm cov hlau; Ntxiv dua thiab, qhov no txawv nyob ntawm seb hom hlau raug sheared.

Rau txoj kab uas hla loj nrog qhov sib txawv loj, cov burrs loj kuj tuaj yeem tshwm sim yog tias qhov chaw sib tw los yog tsis clamped ruaj rau hauv qhov chaw thaum lub sij hawm txiav.

Rau nyias raj txiav, cov txheej txheem txiav tsis yooj yim muab lub mandrel rau hauv qhov chaw. Qhov no ua rau tsis muaj kev txhawb nqa kev txiav tawm, uas ua rau cov yeeb nkab sib tsoo. Qee zaum, lub mandrel tuaj yeem" ntab" los txhawb lub raj ID. Txawm li cas los xij, txoj kev no tsis zoo tag nrho thiab feem ntau ua rau muaj qhov tsis xws luag hauv concentricity lossis qhov kawg tiav. Qhov no yog qhov tseeb tshwj xeeb rau cov ids me, xws li cov uas xav tau rau cov hlab ntsha.

Koj txiav txim siab li cas?

Kev txiav txim siab seb cov txheej txheem hlau shearing yog qhov kev xaiv zoo tshaj plaws txiav tawm yuav tsum muaj kev nkag siab tob txog koj daim ntawv thov tshwj xeeb thiab nws qhov tshwj xeeb. Ua qhov kev xaiv zoo tshaj plaws kuj yuav tsum muaj kev nkag siab txog ntau txoj kev siv los txiav hlau.
