Tom qab ntau xyoo hauv kev lag luam, kuv tau sau cov ntsiab lus tseem ceeb ntawm kev kos duab tas li tuag rau hauv plaub lo lus: "kwj tswj" thiab "synchronization." Cia peb tshuaj xyuas cov txheej txheem no thiab cov ntsiab lus tseem ceeb honed los ntawm kev ua tau zoo:
I. Txheej txheem xam yog tus ntsuj plig: "Navigation Map" ntawm tus txheej txheem kos duab
Ua ntej pib tsim, cov kev suav no yuav tsum tau ua kom zoo:
Tag nrho Drawing Coefficient thiab Pass Allocation
Qhov kawg Formula: mtag nrho= d/D (Workpiece Diameter/Blank Diameter). Qhov no yog tag nrho compression piv.
Txoj Cai Golden rau Pass Allocation: Siv me me pib kos duab coefficient m1(piv txwv li, 0.5-0.55), nce nws incrementally nrog txhua qhov txuas tom ntej (m2≈0.75-0.8, m3≈0.8-0.85). Qhov zais cia nyob rau hauv stretching mus rau qhov txwv nyob rau hauv thawj pass los tsim qhov chaw rau cov txheej txheem tom ntej thiab txo tag nrho cov workstations.
Ironclad Cov Cai rau Txheej Txheem Txheej Txheem
"Kev ncab yuav tsum tau ua raws li shaping, thiab shaping yuav tsum tau ua raws li kev xuas nrig ntaus": Cov txheej txheem kos duab hloov cov khoom thickness thiab qhia springback; yog li ntawd, siab - precision xuas nrig ntaus yuav tsum tsis txhob ua ua ntej los yog thaum lub sij hawm kev kos duab. "Ntev ua ntej, tom qab ntawv": Lwm cov txheej txheem tsim hauv zos xws li flanging thiab bulging yuav tsum tau ua tom qab cov txheej txheem ncab; txwv tsis pub, lawv yuav cuam tshuam loj rau cov khoom ntws.
Blank Development thiab Pre-txiav Design
Nruam stretched blanks yog strips, tsis yog ib tug neeg ncig daim. Cov "bridges" thiab "pre-txiav" ntawm lub sawb yog qhov tseem ceeb heev.
Ua ntej- Cov Ntawv Txiav: Cov khoom ua haujlwm puag ncig feem ntau siv "ob - ntiv nplhaib txiav" lossis "daim duab- yim txiav." Lawv lub luag haujlwm tseem ceeb yog "cais tawm" cov khoom siv los ntawm cov sawb thaum lub sij hawm ncab, txo kev sib nrig sib rub ntawm qhov chaw uas nyob ib sab thiab tiv thaiv wrinkling thiab tawg.
Tus nqi sib tshooj: 30% -50% loj dua li cov neeg tuag zoo tib yam, kom ntseeg tau tias cov sawb tseem muaj zog txaus rau kev pub noj tom qab ntau qhov ncab.
II. Layout Diagram as the Skeleton: The Blueprint Determining the Success or Failure of the Tuag
Qhov no yog qhov uas tus tsim txuj ci yog qhov tseeb tshaj plaws.
Kev Xaiv Ntawm "Ib qho-rau-Ob" thiab "Ib qho-rau-Ib" Pub
Ib -rau-Ob (Dual Feed): Kev siv cov khoom siv siab heev, tab sis yuav tsum muaj kev ua haujlwm siab heev hauv kev coj cov khoom siv sawb thiab ntsuas qhov kev ntxhov siab ntawm qhov tuag. Haum rau cov khoom lag luam nrog cov khoom loj batch loj thiab tswj tus nqi.
Ib -rau-Ib qho (Single Feed): Tus huab tais ntawm kev ruaj ntseg, nrog cov hlua txaus, kev pub mis zoo, thiab lub neej ntev. Kev pom zoo heev, tshwj xeeb tshaj yog rau cov duab kos duab.
Daim duab ntawm qhov chaw nres tsheb Empty
Lub chaw nres tsheb khoob yuav tsum tau teeb tsa ntawm ob qhov chaw kos duab! Qhov no yog qhov tseem ceeb rau kev tso cov khoom siv kev ntxhov siab thiab ua kom yooj yim rau kev teeb tsa ntawm qhov sib txawv ntawm qhov kev hloov kho mechanism. Nws tsis tuaj yeem raug tshem tawm.
"Tool Reception" thiab "Giveaway"
Lub "giveaway kab noj hniav" yuav tsum tau muab milled rau hauv lub phaj tuag nyob ib ncig ntawm daim duab punch kom meej cov duab ib nrab -cov khoom tiav los ntawm daim duab dhau los, tiv thaiv kev cuam tshuam.
Cov khoom seem ntawm lub sawb yuav tsum tau ua kom zoo "tau txais" los xyuas kom meej tias cov khoom seem tuaj yeem txiav tau zoo thiab poob, tsis tsim "caj dab" uas cuam tshuam rau kev pub mis.
III. Tus Qauv Tsim: Dab Ntxwg Nyoog nyob hauv Cov Lus Qhia
Floating Materials thiab Guiding System
Strong Floating Materials: Vim yog qhov siab ntawm cov khoom kos, siab - lub caij nplooj ntoos hlav muaj zog- loaded floating cov khoom pins yuav tsum tau siv, nrog rau qhov tseeb qhov chaw ntawm cov khoom siv ntab kom ntseeg tau tias cov sawb tuaj yeem nqa tau mus rau qhov siab txaus rau kev noj mov zoo.
Kev Taw Qhia Ua Ntej, Nias Tom Qab: Hauv qhov chaw teeb duab kos duab, yuav tsum xub siv tus pin coj los ntsuas qhov chaw ib nrab - cov khoom tiav los ntawm cov txheej txheem dhau los, tom qab ntawd siv lub phaj stripper los nias cov khoom, thiab thaum kawg cov punch nkag mus. Kev ua tsis raug yuav ua rau muaj kev sib tsoo tuag.
Paub meej ntawm Drawing Punch / Tuag
Round Corners: Thawj puag ncig kaum lub vojvoog (rp) rau cov punch yog (4-6) t, nce ntxiv tom qab; thawj puag ncig kaum lub vojvoog (rd) rau qhov tuag yog (6-8)t. Round fab yuav tsum polished rau ib daim iav tiav; Qhov no yog qhov tseem ceeb rau kev txo qis kev sib txhuam thiab tiv thaiv kev tawg.
Clearance: Daim duab clearance Z (ib sab) feem ntau yog (1.1-1.3)t. Tus nqi loj dua yog siv rau thawj daim duab kom haum cov khoom tuab.
Ventilation Qhov: Qhov cua qhov qhov yuav tsum tau drilled ntawm lub punch! Txoj kab uas hla φ1.0-φ2.0, los tiv thaiv cov khoom deformation lossis nqa tawm vim lub tshuab nqus tsev adsorption.
Fine-tuning thiab Compensation Mechanism
Stretch Height Fine-tuning: Thaum lub sij hawm sib dhos, nyias nyias (plug gauge) muab tso rau nruab nrab ntawm lub hauv paus tuag thiab stretching tuag kom meej kho qhov tob ntawm txhua qhov hla. Qhov no yog ib txoj hauv kev tseem ceeb rau kev tuag debugging.
Anti- Sab Nraud Force Design: Thaum lub sijhawm ntau- chaw nres tsheb stretching, lateral quab yuam yog loj heev. Nres cov yuam sij / hnav- cov thaiv tiv thaiv yuav tsum tau muab tso rau hauv lub hauv paus tuag kom tiv thaiv kev tuag.
IV. Cov txuj ci tseem ceeb thiab cov ntsiab lus debugging
Qhov sib npaug ntawm "Anti-wrinkle" thiab "Anti-breakage"
Wrinkling: Ntxiv dag zog rau lub zog los yog ntxiv cov tav tav (grooving ntawm lub nplhaib khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Kev tawg: Txo qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Debugging yog hais txog kev nrhiav qhov zoo tshaj plaws sib npaug ntawm ob qho no.
Lubrication yog "miracle kho"
Nyob rau hauv lub stretching cheeb tsam, cov roj pits los yog cov roj raws yuav tsum tau tsim los xyuas kom meej txaus lubrication thaum lub sij hawm stretching. Kev xaiv cov roj nplua nyeem (kos duab roj, roj sib tov, thiab lwm yam) ncaj qha cuam tshuam rau kev vam meej lossis tsis ua haujlwm.
Sawb End kho
Thaum lub sawb mus txog ob peb kauj ruam kawg, nws yuav sag vim lub zog tsis txaus. Ib txoj hlua txhawb nqa yuav tsum tau tsim los ntawm qhov kawg ntawm qhov tuag los yog ntawm lub tshuab.
V. Tsim Daim Ntawv Teev Npe (Cov Ntsiab Lus Tseem Ceeb)
[ ] Puas yog tag nrho cov duab kos coefficient thiab dhau kev faib khoom tsim nyog? Puas yog thawj daim duab tau siv tag nrho?
[ ] Hauv qhov layout, puas muaj cov chaw ua haujlwm khoob ntawm cov txheej txheem kos duab?
[ ] Puas muaj qhov vents ntawm lub tshuab nqus tsev?
[ ] Puas yog lub kaum sab xis ntawm txhua daim duab tuag cim nrog daim iav polishing?
[ ] Puas yog lub caij nplooj ntoos hlav quab yuam ntawm ntab tus pin txaus? Puas muaj cov pins txwv los tiv thaiv dhau - ntab?
[ ] Cov qauv puas tau ua kom meej meej meej rau txhua qhov ib nrab- cov khoom tiav lawm?
[ ] Puas yog kos duab qhov siab hloov shim qauv tsim?
[ ] Puas yog txoj haujlwm rau qhov nro ribs / zawj tshwj tseg ntawm lub nplhaib siab lossis qauv (ntxiv rau lub sijhawm debugging)?
[ ] Puas yog kev txhawb nqa tau txiav txim siab thaum kawg ntawm daim kab xev?
Thaum kawg, ib lo lus hais txog qhov tseem ceeb ntawm kev ncab txuas ntxiv tuag:
"Layout txiav txim siab qhov xwm txheej tag nrho, lub kaum sab xis txiav txim siab txog lub neej lossis kev tuag, cov khoom ntab ua kom ruaj khov, thiab kev debugging txiav txim qhov tshwm sim."
Cov kev txawj ntse thiab cov ntsiab lus tseem ceeb no tau sau los ntawm suav tsis txheeb hmo ntuj ntawm kev debugging thiab kho pwm. Ua kom tsis tu ncua ncab tuag yuav tsum tau ua siab tawv thiab ua tib zoo, sib txuas txoj kev xav nrog kev xyaum; txhua qhov nthuav dav tsim nyog rov xav txog. Kuv vam tias cov kev paub dhau los no tuaj yeem txhawb lossis txhawb nqa koj. Txais tos kom txuas ntxiv kev sib tham!
