Sheet hlau hemming yog dab tsi?
Ib yam li hauv kev lag luam tsoos tsho thiab xaws khaub ncaws, hemming sheet hlau cuam tshuam cov folding ntawm ib txheej ntawm cov khoom siv rau lwm tus thiaj li tsim tau ib qho muag muag los yog puag ncig.Nws yog siv nyob rau hauv ntau yam kev lag luam xws li tub yees, txee ua, chaw ua hauj lwm cov cuab yeej tsim, khoom noj khoom haus, thiab txee thiab cia khoom cia rau npe rau ob peb tug.
Keeb kwm, hemming feem ntau tau siv rau ntawm cov ntaub ntawv xws li 20 ga.ua 16ga.hlau me me.Txawm li cas los xij, nrog kev txhim kho tsis ntev los no hauv cov cuab yeej siv hemming nws tsis yog qhov tsis yooj yim pom hemming ua tiav ntawm 12 - 14 ga., thiab nyob rau hauv tsawg zaus txawm tias tuab li 8 ga.khoom.
Hemming sheet hlau cov khoom tuaj yeem txhim kho kev zoo nkauj, tshem tawm qhov cuam tshuam ntawm cov npoo ntse thiab burrs nyob rau hauv qhov chaw uas qhov chaw yuav ua rau muaj kev phom sij, thiab ntxiv dag zog rau qhov ua tiav.Xaiv cov cuab yeej hemming txoj cai yog nyob ntawm seb koj yuav hemming ntau npaum li cas thiab cov khoom siv thicknesses koj npaj rau hem.

Daim Ntawv Thov Zoo: Qhov zoo tshaj plaws rau thaum hemming tau ua tsis tu ncua thiab tsis tshua muaj qhov sib txawv ntawm cov khoom tuab.
Universal Bending: Tsis yog
Cov cuab yeej rauj yog txoj kev qub tshaj plaws ntawm hemming.Nyob rau hauv txoj kev no, ntug ntawm cov khoom yog khoov nrog ib txheej ntawm lub kaum sab xis tooling rau ib lub kaum sab xis ntawm kwv yees li 30 °.Thaum lub sijhawm ua haujlwm thib ob, lub flange ua ntej khoov yog flattened hauv qab txheej txheej ntawm cov cuab yeej flattening, uas muaj cov punch thiab tuag nrog lub ntsej muag tiaj tus los tsim cov hem.Vim tias cov txheej txheem xav tau ob lub cuab yeej teeb tsa, cov cuab yeej rauj yog qhov zoo tshaj plaws tshwj tseg raws li kev xaiv nyiaj txiag rau kev ua haujlwm tsis tu ncua.
Max.Khoom thickness: 16 gauge
Daim Ntawv Thov Zoo: Qhov zoo tshaj plaws rau qee lub sijhawm hemming ntawm cov ntaub ntawv nyias.Zoo tagnrho rau "crushed" hems.
Universal dabtsi yog khoov: Yog, tab sis txwv.
Kev sib xyaw ua ke ntawm cov punch thiab tuag (lossis U-shaped hemming tuag) siv 30 ° mob punch nrog lub puab tsaig flattening rau pem hauv ntej thiab U-shaped tuag nrog lub dav tiaj tus saum npoo.Raws li nrog txhua txoj hauv kev hemming, thawj qhov khoov yuav tsim kom muaj 30 ° ua ntej khoov.Qhov no yog ua tiav los ntawm cov punch tsav cov khoom siv rau hauv U-shaped qhib ntawm qhov tuag.Tom qab ntawd cov khoom yog muab tso rau sab saum toj ntawm qhov tuag nrog pre-khoov flange tig upward.Lub punch yog rov qab mus rau hauv U-shaped qhib ntawm qhov tuag thaum lub puab tsaig flattening ntawm lub punch nce mus txog theem flattening.
Vim qhov tseeb tias U-shaped hemming tuag muaj cov phab ntsa ntawm cov hlau hauv qab ntawm qhov chaw ua haujlwm flattening tshwm sim, lub peev xwm thauj khoom siab tau muab los ntawm tus qauv tsim no ua haujlwm zoo heev hauv kev tsim "crushed" hems.Vim yog kev siv cov xuas nrig ntaus rau ua ntej khoov, U-shaped hemming tuag kuj tseem siv tau rau kev siv khoov thoob ntiaj teb.
Kev lag luam tawm rau qhov kev tsim no yog tias lub puab tsaig flattening nyob rau pem hauv ntej ntawm lub punch, nws yuav tsum tau ntiav ntiav nyob rau hauv qhov tob kom tsis txhob cuam tshuam nrog cov khoom thaum nws swings upwards los tsim 30-degree pre-khoov.Qhov tob tob no ua rau cov khoom siv ntau dua los ntawm lub puab tsaig flattening thaum lub sij hawm flattening, uas tuaj yeem ua rau muaj kev puas tsuaj loj rau cov xovxwm nres lub nraub qaum ntsuas ntiv tes.Feem ntau, qhov no yuav tsum yog qhov teeb meem tshwj tsis yog tias cov khoom siv yog galvanized steel, muaj cov roj rau ntawm qhov chaw, lossis yog tias lub flange ua ntej yog khoov rau lub kaum sab xis uas muaj ntau dua (qhib ntau dua) ntau dua 30 °.

Daim Ntawv Thov Zoo: Rau qhov tsis tshua muaj rau nruab nrab hemming daim ntawv thov ntawm ntau yam khoom thicknesses.
Universal Bending: Yog
Raws li xovxwm nres thiab software muaj peev xwm nce, ob theem hemming tuag tau nrov heev.Thaum siv cov tuag no, ib feem yog khoov nrog 30 ° mob lub kaum ntse ntse punch thiab hemming tuag nrog 30 ° mob lub kaum V-qhib.Lub sab sauv ntawm cov tuag no yog caij nplooj ntoos hlav loaded thiab thaum lub sij hawm flattening theem, cov khoom pre-bent yog muab tso rau ntawm ib tug txheej ntawm flattening puab tsaig nyob rau hauv pem hauv ntej ntawm lub tuag thiab lub puab tsaig sab sauv lub puab tsaig yog tsav downward los ntawm lub punch thaum lub sij hawm stroke ntawm lub ram.Raws li qhov no tshwm sim, lub pre-bent flange yog flattened kom txog rau thaum cov ntug kev sib cuag nrog cov ntawv tiaj tus.
Thaum ceev thiab ua tau zoo, ob theem hemming tuag muaj lawv qhov tsis zoo.Vim tias lawv siv lub caij nplooj ntoos hlav loaded saum toj, lawv yuav tsum muaj lub caij nplooj ntoos hlav txaus los tuav daim ntawv yam tsis poob txawm tias me ntsis kom txog rau thaum thawj qhov khoov pib.Yog tias lawv tsis ua li ntawd, cov khoom tuaj yeem plam hauv qab cov ntiv tes rov qab thiab ua rau lawv puas tsuaj raws li thawj qhov khoov tau ua.Tsis tas li ntawd, lawv xav tau V-qhib uas yog sib npaug rau 6 npaug ntawm cov khoom tuab (piv txwv li, rau cov khoom siv nrog lub thickness ntawm 2 hli, lub caij nplooj ntoos hlav loaded hemming tuag yuav tsum muaj 12 hli v-qhib).

Ideal Application: Zoo tagnrho rau kev ua haujlwm hemming nquag.
Universal Bending: Yog.Qhov ntau yam kev xaiv rau ob qho tib si hemming thiab universal dabtsi yog khoov.
Undoubtedly, niaj hnub thiab feem ntau tsim kev loj hlob ntawm hemming tooling yog "Dutch dabtsi yog khoov rooj," uas yog tseem hu ua yooj yim raws li ib tug "hemming rooj."Ntau yam zoo li lub caij nplooj ntoos hlav-loaded hemming tuag, Dutch bending ntxhuav feature ib txheej ntawm flattening puab tsaig nyob rau hauv pem hauv ntej.Txawm li cas los xij, tsis zoo li lub caij nplooj ntoos hlav-loaded hemming tuag, lub puab tsaig flattening ntawm lub rooj khoov Dutch yog tswj los ntawm hydraulic thooj voos kheej kheej.Lub tog raj kheej hydraulic ua rau nws muaj peev xwm ua kom muaj ntau yam ntawm cov khoom tuab thiab qhov hnyav vim tias qhov teeb meem ntawm lub caij nplooj ntoos hlav siab raug tshem tawm.
Ua ob npaug raws li tus neeg tuav tuag, Dutch cov rooj khoov kuj tseem muaj peev xwm hloov pauv 30-degree tuag, uas tseem ua rau lawv muaj peev xwm ua rau ntau yam ntawm cov khoom thicknesses.Qhov no ua rau lawv muaj ntau yam ntau yam thiab ua rau txo qis hauv lub sijhawm teeb tsa.Muaj peev xwm hloov qhov v-qhib, ua ke nrog lub peev xwm siv lub tog raj kheej hydraulic los kaw lub puab tsaig flattening kuj ua rau nws muaj peev xwm siv lub kaw lus ua tus tuav tuag thaum tsis siv rau kev siv hemming.
