Muaj ntau ntau txoj hauv kev los curl lossis nthuav daim di ncauj ntawm qhov cylindrical. Piv txwv li, qhov no tuaj yeem ua tiav siv lub tshuab xovxwm lossis orbital molding tshuab. Txawm li cas los xij, qhov teeb meem nrog cov txheej txheem no (tshwj xeeb tshaj yog thawj tus) yog tias lawv xav tau ntau lub zog.
Qhov no tsis yog qhov zoo tagnrho rau cov khoom me me los yog cov khoom ua los ntawm cov khoom siv uas tsis tshua muaj ductile. Rau cov ntawv thov no, ib txoj kev thib peb tshwm sim: profileing.
Zoo li orbital thiab radial forming, dov yog ib qho tsis cuam tshuam cov txheej txheem ntawm kev sib sau ntawm cov hlau. Txawm li cas los xij, es tsis txhob tsim lub taub hau los yog rivet, cov txheej txheem no tsim ib qho curl los yog ntug ntawm ntug los yog ntug ntawm ib qho hollow cylindrical piece. Qhov no tuaj yeem ua kom ruaj ntseg rau ib qho khoom siv (xws li cov kabmob lossis lub hau) hauv lwm cov khoom, lossis tsuas yog kho qhov kawg ntawm lub raj hlau kom nws muaj kev nyab xeeb, txhim kho nws cov tsos, lossis ua kom yooj yim rau ntxig lub raj. mus rau hauv nruab nrab ntawm lub raj hlau. lwm qhov.
Nyob rau hauv orbital thiab radial forming, lub taub hau yog tsim los ntawm ib tug rauj lub taub hau txuas mus rau ib tug rotating spindle, uas ib txhij ua ib tug downward quab yuam ntawm lub workpiece. Thaum profileing, ob peb rollers yog siv los ntawm nozzles. Lub taub hau tig ntawm 300 mus rau 600 rpm, thiab txhua qhov hla ntawm cov menyuam maj mam thawb thiab smoothes cov khoom mus rau hauv ib qho seamless, ruaj zoo. Hauv kev sib piv, kev ua haujlwm ua haujlwm yog feem ntau khiav ntawm 1200 rpm.
"Cov hom orbital thiab radial yog qhov zoo dua rau cov khoom rivets. Nws zoo dua rau cov khoom siv tubular, "said Tim Lauritzen, cov khoom siv hluav taws xob ntawm BalTec Corp.
Cov rollers hla lub workpiece raws ib txoj kab ncaj nraim ntawm kev sib cuag, maj mam shaping cov khoom mus rau hauv cov duab xav tau. Cov txheej txheem no yuav siv sijhawm li 1 txog 6 vib nas this.
Brian Wright, tus lwm thawj ntawm kev muag khoom ntawm Orbitform Group tau hais tias "[lub sijhawm pwm] nyob ntawm cov khoom, nws yuav tsum tau txav mus deb npaum li cas thiab qhov geometry ntawm cov khoom yuav tsum tau tsim,". "Koj yuav tsum xav txog phab ntsa tuab thiab lub zog tensile ntawm cov yeeb nkab."
Lub yob tuaj yeem tsim los ntawm sab saum toj mus rau hauv qab, hauv qab mus rau sab saum toj lossis sab. Qhov tsuas yog yuav tsum tau yog kom muaj chaw txaus rau cov cuab yeej.
Cov txheej txheem no tuaj yeem tsim ntau yam ntaub ntawv, suav nrog tooj dag, tooj liab, cam khwb cia txhuas, me me steel, siab carbon steel, thiab stainless hlau.
Lauritzen hais tias "Cast aluminium yog cov khoom siv zoo rau yob txoj kev vim tias hnav tuaj yeem tshwm sim thaum tsim," Lauritzen hais. “Qee lub sij hawm nws yuav tsum tau lubricate qhov chaw kom txo qis hnav. Qhov tseeb, peb tau tsim ib qho system uas lubricates cov menyuam thaum lawv zoo li cov khoom. "
Roll forming tuaj yeem siv los tsim cov phab ntsa uas yog 0.03 txog 0.12 ntiv tes tuab. Txoj kab uas hla ntawm cov hlab no txawv ntawm 0.5 mus rau 18 ntiv tes. Wright hais tias "Feem ntau daim ntawv thov nyob nruab nrab ntawm 1 thiab 6 ntiv tes hauv txoj kab uas hla," Wright hais.
Vim hais tias ntawm qhov ntxiv torque tivthaiv, yob txoj kev yuav tsum tau 20% tsawg downward quab yuam los ua ib tug curl los yog ntug tshaj ib tug crimper. Yog li ntawd, cov txheej txheem no yog tsim rau cov khoom tawg yooj yim xws li cam khwb cia txhuas thiab cov khoom rhiab xws li sensors.
Wright hais tias "Yog tias koj yuav tsum siv lub xovxwm los tsim lub raj sib dhos, koj yuav xav tau li tsib zaug ntau npaum li yog tias koj yuav tsum siv yob txoj kev," Wright hais. "Cov rog siab dua ua rau muaj kev pheej hmoo ntawm cov yeeb nkab txuas lossis khoov, yog li tam sim no cov cuab yeej tau dhau los ua nyuaj thiab kim.
Muaj ob hom ntawm cov menyuam taub hau: static roller hau thiab articulated hau. Static headers yog cov feem ntau. Nws muaj vertically oriented scroll log nyob rau hauv ib tug preset txoj hauj lwm. Lub zog tsim yog siv vertically rau lub workpiece.
Nyob rau hauv sib piv, ib tug pivot lub taub hau muaj horizontally oriented rollers mounted rau pins uas txav synchronously, zoo li lub chuck puab tsaig ntawm ib tug laum xovxwm. Cov ntiv tes txav cov menyuam radially mus rau hauv molded workpiece thaum ib txhij siv lub clamping load rau lub rooj sib txoos. Hom lub taub hau no yuav pab tau yog tias qhov chaw ntawm lub rooj sib txoos protrude saum lub qhov nruab nrab.
Wright piav qhia "Qhov no siv quab yuam los ntawm sab nraud hauv," Wright piav qhia. "Koj tuaj yeem crimp sab hauv lossis tsim cov khoom xws li O-ring grooves lossis undercuts. Lub taub hau tsav tsuas yog txav lub cuab yeej nce thiab nqis raws Z axis. "
Cov txheej txheem pivot rau cov menyuam feem ntau yog siv los npaj cov kav dej rau kev teeb tsa. "Cov txheej txheem no yog siv los tsim ib qho zawj rau sab nraud ntawm qhov chaw thiab ib qho kev sib raug zoo ntawm sab hauv ntawm qhov chaw uas ua haujlwm nruj rau cov kabmob," Wright piav qhia. "Tom qab ntawd, thaum cov kabmob nyob hauv, koj ua qhov kawg ntawm lub raj kom ruaj ntseg cov kabmob. Yav dhau los, cov neeg tsim khoom yuav tsum tau txiav lub xub pwg mus rau hauv lub raj raws li kev txwv tsis pub. "
Thaum nruab nrog ib qho ntxiv ntawm vertically adjustable internal rollers, qhov sib koom ua ke tuaj yeem tsim ob qho tib si sab nraud thiab sab hauv txoj kab uas hla ntawm lub workpiece.
Txawm hais tias zoo li qub los yog articulated, txhua tus menyuam thiab cov menyuam lub taub hau sib dhos yog kev cai tsim rau ib daim ntawv thov tshwj xeeb. Txawm li cas los xij, cov menyuam lub taub hau yog hloov tau yooj yim. Qhov tseeb, tib lub tshuab yooj yim tuaj yeem ua txoj kev tsheb ciav hlau thiab dov. Thiab zoo li orbital thiab radial forming, yob txoj kev tuaj yeem ua tau raws li cov txheej txheem ib leeg-automated ib leeg lossis koom ua ke rau hauv qhov kev sib dhos tag nrho.
Cov chais yog tsim los ntawm cov cuab yeej hardened steel thiab feem ntau yog li ntawm 1 mus rau 1.5 nti hauv txoj kab uas hla, Lauritzen tau hais. Tus naj npawb ntawm cov chais rau ntawm lub taub hau yog nyob ntawm qhov tuab thiab cov khoom siv ntawm ib feem, nrog rau cov nyiaj siv zog. Feem ntau siv yog peb-roller ib qho. Qhov me me yuav tsum tau tsuas yog ob lub chais, hos qhov loj heev yuav xav tau rau.
"Nws nyob ntawm daim ntawv thov, nyob ntawm qhov loj thiab txoj kab uas hla ntawm ib feem thiab ntau npaum li cas koj xav txav cov khoom," Wright hais.
Wright tau hais tias "Ninety-tsib feem pua ntawm cov ntawv thov yog pneumatic," Wright hais. "Yog tias koj xav tau kev ua haujlwm siab lossis chav ua haujlwm huv, koj xav tau cov tshuab hluav taws xob."
Qee zaum, cov ntaub qhwv lub siab tuaj yeem ua rau hauv lub kaw lus kom siv cov khoom ua ntej rau cov khoom ua ntej molding. Qee zaum, ib qho kev hloov pauv hloov pauv hloov pauv tuaj yeem ua rau hauv cov ntaub ntawv clamping los ntsuas cov pawg qhov siab ntawm cov khoom ua ntej sib dhos ua kev kuaj xyuas zoo.
Cov kev hloov pauv tseem ceeb hauv cov txheej txheem no yog axial quab yuam, radial quab yuam (nyob rau hauv cov ntaub ntawv ntawm articulated roller forming), torque, rotation ceev, lub sij hawm thiab kev khiav hauj lwm. Cov kev teeb tsa no yuav sib txawv nyob ntawm qhov loj me, cov khoom siv, thiab cov kev xav tau ntawm lub zog. Zoo li kev nias, orbital thiab radial txoj kev ua haujlwm, kev tsim cov tshuab tuaj yeem tsim los ntsuas kev quab yuam thiab hloov pauv lub sijhawm.
Cov neeg muab khoom siv tuaj yeem muab cov kev taw qhia ntawm qhov pom tsis zoo nrog rau kev taw qhia ntawm kev tsim ib feem preform geometry. Lub hom phiaj yog rau cov khoom siv kom ua raws li txoj hauv kev uas tsis muaj zog tsawg. Kev txav ntawm cov khoom siv yuav tsum tsis txhob tshaj qhov kev ncua deb uas yuav tsum tau ua kom ruaj ntseg ntawm kev sib txuas.
Hauv kev lag luam tsheb, txoj kev no yog siv los sib sau ua ke solenoid li qub, sensor vaj tsev, cam followers, pob qij txha, shock absorbers, lim, roj twj, twj tso kua mis, dej twj, nqus twj, hydraulic li qub, khi pas nrig, airbag sib dhos, steering kab, thiab antistatic shock absorbers Thaiv tus nres manifold.
Lauritzen hais tias "Peb tsis ntev los no tau ua haujlwm ntawm ib daim ntawv thov uas peb tau tsim lub chrome cap hla lub threaded insert los sib sau ua ke cov txiv ntoo zoo," Lauritzen hais.
Ib tus neeg muag khoom siv tsheb siv yob txoj hauv kev kom ruaj ntseg bearings hauv lub cam khwb cia txhuas dej twj tso kua mis vaj tsev. Lub tuam txhab siv cov nplhaib tuav kom ruaj ntseg cov bearings. Rolling tsim kom muaj kev sib koom ua ke zoo dua thiab txuag cov nqi ntawm lub nplhaib, nrog rau lub sijhawm thiab kev siv nyiaj ntawm grooving lub nplhaib.
Hauv kev lag luam khoom siv kho mob, profileing yog siv los ua cov pob qij txha thiab cov lus qhia catheter. Hauv kev lag luam hluav taws xob, profileing yog siv los sib sau cov ntsuas, qhov (socket), capacitors thiab roj teeb. Aerospace assemblers siv yob txoj kev los tsim bearings thiab poppet li qub. Cov thev naus laus zis tseem siv los ua cov khoom siv hluav taws xob hauv chaw pw hav zoov, cov rooj pom tawg, thiab cov yeeb nkab fittings.
Kwv yees li 98% ntawm kev tsim khoom hauv Tebchaws Meskas yog los ntawm cov lag luam me thiab nruab nrab. Koom nrog Greg Whitt, Tus Thawj Saib Xyuas Kev Txhim Kho ntawm RV cov chaw tsim khoom MORryde, thiab Ryan Kuhlenbeck, CEO ntawm Pico MES, thaum lawv sib tham txog yuav ua li cas cov lag luam loj tuaj yeem txav los ntawm phau ntawv mus rau digital manufacturing, pib hauv khw hauv pem teb.
Peb lub neej tab tom ntsib teeb meem kev lag luam, kev sib raug zoo thiab ib puag ncig uas tsis tau pom dua. Tus kws tshaj lij kev tswj hwm thiab tus sau Olivier Larue ntseeg hais tias lub hauv paus rau kev daws teeb meem ntau ntawm cov teeb meem no tuaj yeem pom nyob rau hauv qhov chaw xav tsis thoob: Toyota Production System (TPS).
