Lub sij hawm hemming muaj nws keeb kwm hauv cov ntaub ua qhov twg ntug ntawm daim ntaub yog folded rov qab rau nws tus kheej thiab ces stitched kaw.Nyob rau hauv daim ntawv hlau hemming txhais tau hais tias quav hlau rov qab rau nws tus kheej.Thaum ua haujlwm nrog Brake Press hems yeej ib txwm tsim nyob rau hauv ob kauj ruam txheej txheem:
Tsim khoov nrog Acute Angle Tooling hauv cov hlau, 30 ° yog qhov zoo dua tab sis 45 ° yuav ua haujlwm rau qee qhov xwm txheej.
Muab qhov khoov mob rau hauv ib lub tiaj tiaj thiab siv lub zog txaus kom kaw qhov khoov kom tiav.
Thawj kauj ruam yog ua tiav tib yam li ib txwm mob lub kaum sab xis khoov.Qhov thib ob theem ntawm cov txheej txheem hemming yuav tsum muaj qee qhov kev paub ntxiv txog kev ua haujlwm ntawm Brake Press tus neeg teb xov tooj thiab tus tsim cov cuab yeej vim tias lub kaum sab xis ntawm cov ntawv hlau, lub tiaj tus bar xav kom swb thiab deb ntawm cov ntawv hlau.Tsis tas li ntawd, lub workpiece xav kom xaub tawm ntawm cov tuav.Ob lub zog no hu ua thrust force.
Piv txwv ntawm Thrust Forces Los ntawm Hemming Sheet Hlau
Qhov no yuav tsum tau kom lub flattening tuag yog tsim los tiv thaiv lub zog thrust thiab nyob twj ywm.Tsis tas li ntawd nws yuav tsum kom tus neeg teb xov tooj muab lub zog rau pem hauv ntej tiv thaiv cov ntawv hlau los tiv thaiv nws los ntawm zawv zawg tawm ntawm qhov tuag.Cov rog no tseem ceeb tshaj plaws ntawm cov khoom ua haujlwm tuab nrog cov flanges luv.Nrog rau cov xwm txheej hauv siab cia peb tshuaj xyuas peb ntawm ntau hom kev hemming teeb tsa thiab cov cuab yeej muaj rau cov xovxwm nres.
Multi Tool Setup, Acute Tooling thiab Flattening Tuag
Daim ntawv yooj yim tshaj plaws ntawm hemming teeb yog sib txuas ob qhov sib txawv.Thawj yog qhov kev teeb tsa mob hnyav, qhov twg 30 ° khoov yog tsim los siv cov cuab yeej txheem.Thaum thawj qhov khoov tau ua rau qhov yog hloov mus rau lwm lub tshuab, lossis ib qho kev teeb tsa tshiab tau muab tso rau hauv qhov qub.Qhov thib ob teeb yog ib qho yooj yim flattening bar.Lub khoov yog muab tso rau hauv qab lub flattening bar thiab kaw.Qhov kev teeb tsa no tsis tas yuav muaj cov cuab yeej tshwj xeeb thiab tej zaum yuav zoo dua rau kev ua haujlwm luv luv, cov qauv siv los yog cov khw muag khoom ua haujlwm uas yuav xav tau los tsim ntau qhov ntev.Raws li ib tug neeg daim ntawm Nres Xovxwm Tooling tus mob tooling thiab flattening bar muaj ntau yam, thiab ntxiv tus nqi sab nraum hemming.Qhov kos rov qab mus rau qhov system no yog qhov yuav tsum tau muaj ntawm ob qhov kev teeb tsa tshwj xeeb, zoo li tsis muaj kev tswj hwm kev sib tw hauv cov txheej txheem flattening.
Ob theem Hemming Punch thiab Tuag Combination
Ob theem hemming tuag ua haujlwm los ntawm kev siv qhov sib sib zog nqus channel tuag thiab ib rab ntaj mob hnyav.Thawj khoov siv cov channel raws li av qhib rau huab cua tsim khoov.Hauv theem thib ob, cov punch swb mus rau hauv cov channel raws li cov punch raug kaw thiab cov npoo ntawm cov punch yog siv los ua kom cov ntawv hlau.Zaum lub punch nyob rau hauv qhov tuag channel redirects lub zog thrust rau hauv tuag, uas yuav tau yooj yim nkag tau yooj yim dua li lub punch nws tus kheej.Qhov tsis zoo rau hom kev tuag no yog tias nws xyaum xav tau CNC tswj.Vim tias qhov sib txawv ntawm qhov siab ntawm qhov mob stroke ntawm thawj thiab thib ob theem los kho manually yuav siv sij hawm ntau heev.Tsis tas li ntawd, hom kev tuag no tuaj yeem yooj yim faib los ntawm ntau tshaj tonnage, txhawb kev xav tau kev tswj hwm lub computer.
Peb Theem Hemming Punch Thiab Tuag
Lwm hom khoom siv feem ntau tsim tshwj xeeb rau kev tsim hems yog peb theem, lossis accordion hom punch thiab tuag.Lub v qhib zaum saum lub caij nplooj ntoos hlav loaded ncoo, uas zaum saum lub ncoo hauv qab.Nyob rau hauv thawj theem qhov khoov mob yog tsim nyob rau hauv lub v qhib tom qab lub caij nplooj ntoos hlav tau compressed thiab lub Upper pad yog zaum ntawm lub ncoo qis.Nyob rau theem thib ob lub ram sab saud yog thim rov qab thiab cov springs ntawm lub sab sauv thiab qis dua rov qab mus rau nws qhov qub.Cov ntawv hlau yog tom qab ntawd muab tso rau nruab nrab ntawm lub ncoo sab sauv thiab qis thiab cov punch raug kaw cia xa cov tonnage los ntawm v tuag.Kev pab tshwj xeeb yog muab rau v tuag kom tso cai rau cov cuab yeej no ntawm cov cuab yeej sib cuam tshuam.Cov lus qhia nruab nrab ntawm lub ncoo sab sauv thiab sab qis tiv thaiv lub zog thrust los ntawm kev cuam tshuam rau lwm qhov ntawm cov cuab yeej.Qhov qis dua tuag kuj muab rau tus neeg teb xov tooj ib yam dab tsi los thawb cov khoom ua haujlwm tiv thaiv kev tiv thaiv cov ntawv hlau los ntawm zawv zawg tawm.Cov cuab yeej no yog qhov nyiam rau cov neeg kho tshuab, tsis yog CNC, nres vim qhov sib txawv ntawm qhov siab ntawm cov hlab ntsha me me, ua rau kev hloov kho siv sijhawm tsawg.Qhov kev teeb tsa no kuj tso cai rau koj siv tus qauv mob hnyav.
Tonnage Yuav Tsum Tau Rau Hemming
Lub tonnage xav tau rau hemming yuav nyob ntawm seb lub zog ntawm koj cov khoom, nws thickness thiab qhov tseem ceeb tshaj plaws hom hem koj xav tsim.Lub kua muag poob thiab qhib hems tsis xav tau ze li ntawm tonnage ntau npaum li lub tiaj tus hem.Qhov no yog vim tias koj tsuas yog hloov lub vojvoog sab hauv me me, qhov pib koj tsuas yog txuas ntxiv khoov dhau los 30 °.Thaum koj flatten cov hlau koj tab tom tsim ib lub crease thiab tshem tawm sab hauv lub vojvoog.Tam sim no koj tab tom tsim cov hlau ntau dua li tsuas yog khoov nws.Hauv qab no koj tuaj yeem pom daim ntawv qhia hemming tonnage rau txias dov hlau.
Siv rau Hems
Hems feem ntau yog siv los rov tswj xyuas, zais qhov tsis zoo thiab muab cov ntug kev nyab xeeb dua los daws.Thaum tus tsim hu kom muaj kev nyab xeeb, txawm tias ntug tus nqi ntxiv ntawm cov khoom siv thiab kev ua cov hem feem ntau nyiam rau lwm cov txheej txheem kho ntug.Cov neeg tsim qauv yuav tsum saib dhau ntawm ib qho me me tiaj tus hem kom kho cov npoo.Doubling ib lub hem tuaj yeem tsim kom muaj kev nyab xeeb zoo kawg nkaus los ua haujlwm yam tsis xav txog qhov pib ntawm ntug zoo.Ntxiv ib lub hem nyob rau hauv 'nruab nrab' ntawm qhov khoov profile tuaj yeem qhib lub qhov rooj rau ntau yam profiles tsis tuaj yeem tsis muaj fasteners lossis vuam.Txawm tias tsis muaj cov tshuab seaming zoo sib xyaw ua ke ntawm ob lub hems tuaj yeem tsim muaj zog, nruj pob qij txha nrog me me los yog tsawg kawg fastening.Hems tuaj yeem siv los ua kom zoo dua ob npaug ntawm cov tuab ntawm cov hlau hauv thaj chaw ntawm ib feem uas yuav xav tau kev txhawb nqa ntxiv.Hems siv nyob rau hauv kev lag luam khoom noj khoom haus yuav tsum yuav luag ib txwm raug kaw kom huv si (yooj yim heev los ntxuav hauv qhov qhib).
Ob Chav Hem Ntug - Hem Thiab Ob Chav Hlau Thickness Khoov Rau Kev Txhawb - Siv Lub Hws Los Tsim Cov Profiles Advanced
Kev txiav txim siab tiaj tus qauv ntawm Hems
Lub tiaj tus qauv ntawm ib tug hem tsis yog xam nyob rau hauv tib lub zam raws li ib tug raug khoov.Qhov no yog vim qhov tseeb tias yam xws li Sab Nraud Setback thiab K-Factor ua tsis muaj txiaj ntsig zoo li lub apex ntawm khoov txav mus rau qhov tsis muaj tseeb.Kev sim xam cov nyiaj pub rau ib lub hem zoo li no yuav ua rau muaj kev ntxhov siab xwb.Hloov txoj cai ntawm tus ntiv tes xoo ntawm 43% cov khoom tuab yog siv thaum xam cov nyiaj pub dawb.Piv txwv li yog tias peb cov khoom yog .0598 "thiab peb xav ua kom tiav 1/2" hem peb yuav muab 43% ntawm .0598, .0257 thiab ntxiv rau qhov 1/2 "muab peb 0.5257".Yog li peb yuav tsum tawm 0.5257 "ntawm qhov kawg ntawm lub tiaj tus qauv kom ua tiav 1/2" hem.Nws yuav tsum raug sau tseg tias txoj cai ntawm tus ntiv tes xoo no tsis yog 100% raug.Yog tias koj xav tsim kom muaj qhov raug siab hem koj yuav tsum tau khoov ib qho qauv, ntsuas thiab kho koj cov layouts.Nws yog qhov zoo los ua qhov no rau koj cov ntaub ntawv hemmed feem ntau thiab tsim ib daim ntawv qhia rau yav tom ntej siv.Qhov tsawg kawg nkaus qhov loj los yog qhov ntev ntawm lub hem yuav txiav txim siab los ntawm koj qhov v qhib ntawm koj qhov tuag.Nws yuav yog qhov zoo los xyuas koj qhov ntev ntawm lub hem tom qab khoov vim tias cov kauj ruam kawg ntawm flattening cov hlau tuaj yeem ua rau me ntsis tsis paub txog qhov nws stretches thiab flattens.Siv tus qauv yam tsawg kawg nkaus flange ntev yuav tsum tau kom koj kaw txaus rau feem ntau daim ntawv thov.Nco ntsoov lub Air Khoov Force Chart qhov tsawg kawg nkaus flange ntev rau cov cuab yeej mob yog:
