Qhov tseeb, qhov no tsis zoo li nws yog ua los ntawm cov ntawv hlau. Qee cov profiles muaj cov kev taw qhia lossis cov grooves uas ua rau qhov zoo li nws tau kub forged los yog extruded, tab sis qhov no tsis yog li ntawd. Qhov no yog ib qho profile ua los ntawm kev siv cov txheej txheem txias txias ntawm lub tshuab yob txoj kev, ib lub tshuab uas Welser Profile cov lag luam nyob sab Europe tau ua tiav thiab patented hauv Asmeskas thiab lwm lub teb chaws. Nws tau thov rau nws thawj patent hauv 2007.
"Welser tuav patents rau thickening, thinning thiab txias ua grooves nyob rau hauv profiles," Johnson hais. "Nws tsis yog machining, nws tsis yog thermoforming. Tsawg tus neeg hauv Asmeskas ua nws, lossis tseem sim. "
Txij li thaum profileing yog ib qho kev siv tshuab loj heev, ntau tus tsis xav tias yuav pom qhov xav tsis thoob hauv cheeb tsam no. Ntawm FABTECH®, tib neeg luag nyav thiab co taub hau thaum lawv pom muaj zog fiber ntau lasers txiav ntawm breakneck ceev los yog automated dabtsi yog khoov tshuab kho cov khoom tsis sib haum. Nrog rau txhua qhov kev nce qib hauv cov thev naus laus zis tsim khoom hauv xyoo tas los no, lawv tau cia siab tias yuav muaj kev xav tsis thoob. Lawv tsis xav tias yob txoj kev ua rau lawv xav tsis thoob. Tab sis, raws li cov engineers 'qhia kuv paj" nqe lus qhia, profileing tseem tshaj qhov kev cia siab.
Xyoo 2018, Welser tau nkag mus rau Asmeskas kev lag luam nrog kev nrhiav tau ntawm Superior Roll Forming hauv Valley City, Ohio. Johnson tau hais tias qhov kev txav mus los yog qhov kev tawm tsam, tsis yog tsuas yog nthuav dav Welser lub xub ntiag nyob rau hauv North America, tab sis kuj vim tias Superior Roll Forming qhia ntau yam ntawm Welser txoj kev coj noj coj ua thiab kev pom zoo.
Ob lub tuam txhab tsom mus kov yeej cov chaw tshwj xeeb ntawm kev lag luam txias dov nrog ob peb tus neeg sib tw. Ob lub koom haum tseem tab tom ua haujlwm kom tau raws li kev lag luam xav tau kom sib zog. Cov khoom yuav tsum tau ua ntau dua, muaj zog dua thiab hnyav dua.
Superior tsom rau kev lag luam tsheb; thaum ob lub tuam txhab ua haujlwm rau ntau tus neeg siv khoom, Welser tsom mus rau lwm yam kev lag luam xws li kev tsim kho, kev ua liaj ua teb, hnub ci thiab txee. Lub teeb yuag hauv kev lag luam automotive ib txwm tsom rau cov ntaub ntawv muaj zog, uas kuj yog qhov zoo ntawm Superior. Qhov yooj yim geometry ntawm ib tug khoov profile mus unnoticed kom txog rau thaum engineers pom lub zog ntawm cov khoom khoov. Cov kws tshaj lij engineers feem ntau tsim cov kev pab cuam siv cov khoom siv nrog lub zog tensile ntawm 1400 lossis 1700 MPa. Qhov ntawd yog yuav luag 250 KSI. Hauv Tebchaws Europe, Welser Profile engineers kuj tau hais txog qhov teeb meem ntawm lub teeb, tab sis ntxiv rau kev siv cov ntaub ntawv muaj zog, lawv kuj tau hais txog nws nrog txoj kev molding.
Welser Profile's patented txias forming txheej txheem yog tsim rau cov ntaub ntawv uas tsis muaj zog, tab sis cov geometry tsim los ntawm yob txoj kev tshuab pab txo qhov hnyav ntawm tag nrho cov sib dhos. Lub geometry tuaj yeem tso cai rau qhov profile los ua ntau yam haujlwm thaum txo tus lej ntawm qhov chaw (tsis hais txog cov nyiaj siv rau kev tsim khoom). Piv txwv li, profiled grooves tuaj yeem tsim cov kev sib txuas sib txuas uas tshem tawm cov vuam lossis cov fasteners. Los yog cov duab ntawm qhov profile tuaj yeem ua rau tag nrho cov qauv nruj dua. Tej zaum qhov tseem ceeb tshaj plaws, Welser tuaj yeem tsim cov profiles uas tuab dua hauv qee qhov chaw thiab nyias nyias hauv lwm tus, muab lub zog rau qhov xav tau thaum txo qhov hnyav tag nrho.
Cov kws tsim qauv tsim qauv thiab cov qauv tsim ua raws li txoj cai kev ua haujlwm ntev kaum xyoo: zam lub voj voog me me, cov ceg luv luv, 90-degree khoov, sib sib zog nqus geometries, thiab lwm yam. "Yog lawm, peb ib txwm muaj 90s nyuaj," Johnson hais.
Qhov profile zoo li extrusion, tab sis nws yog txias-tsim los ntawm Welser Profile.
Yog lawm, engineers xav kom yob txoj kev tshuab ua txhaum cov cai ntawm kev tsim khoom, thiab qhov no yog qhov uas cov cuab yeej thiab kev tsim vaj tsev muaj peev xwm ntawm lub khw yob tuaj rau hauv kev ua si. Cov kws tshaj lij ntxiv tuaj yeem ua tiav cov txheej txheem (kev tsim denser 90-degree, sib sib zog nqus geometries) thaum txo cov nqi cuab yeej thiab cov txheej txheem sib txawv, qhov sib tw ntau dua lub tshuab yob txoj kev yuav.
Tab sis raws li Johnson piav qhia, qhov txias txias hauv lub tshuab dov yog ntau dua li qhov ntawd. Cov txheej txheem no tso cai rau koj kom tau txais ib feem profiles uas feem ntau engineers yuav tsis txawm xav txog siv profileing. "Xav txog ib txoj hlua ntawm cov ntawv hlau uas tau dhau los ntawm cov txheej txheem dov, tej zaum 0.100 ntiv tes tuab. Peb tuaj yeem ua tus T-qhov nyob hauv qab nruab nrab ntawm qhov profile no. yuav tsum tau kub dov los yog machined nyob ntawm tolerances thiab lwm yam uas yuav tsum tau, tab sis peb yuav tau yooj yim yob no geometry. "
Cov ntsiab lus tom qab cov txheej txheem yog cov cuab yeej ntawm lub tuam txhab thiab Welser tsis qhia tawm cov qauv paj. Tab sis Johnson tau hais txog qhov laj thawj rau ntau qhov txheej txheem.
Cia peb ua ntej xav txog kev ua haujlwm embossing ntawm lub xovxwm stamping. “Thaum koj compress, koj kuj ncab lossis compress. Yog li koj ncab cov khoom siv thiab txav mus rau ntau qhov chaw ntawm lub cuab yeej [nto], ib yam li koj sau hauv radii ntawm lub cuab yeej. Tab sis [hauv profiling] Cov txheej txheem txias txias no zoo li rau sau radii ntawm steroids. "
Kev ua haujlwm txias ua kom cov khoom muaj zog hauv qee qhov chaw, qhov no tuaj yeem tsim kho kom zoo dua ntawm tus tsim qauv. Txawm li cas los xij, lub tshuab profileing yuav tsum tau coj mus rau hauv tus account cov kev hloov pauv hauv cov khoom siv. Johnson hais tias "Koj tuaj yeem pom qhov kev nce qib tseem ceeb hauv kev ua haujlwm, qee zaum txog 30 feem pua," Johnson hais ntxiv tias qhov kev nce no yuav tsum tau tsim rau hauv daim ntawv thov txij thaum pib.
Txawm li cas los xij, qhov txias txias ntawm Welser Profile tuaj yeem koom nrog kev ua haujlwm ntxiv xws li stitching thiab vuam. Raws li nrog cov pa profileing, kev tho tuaj yeem ua tiav ua ntej, thaum lub sijhawm, lossis tom qab profileing, tab sis cov cuab yeej siv yuav tsum coj mus rau hauv tus account qhov cuam tshuam ntawm kev ua haujlwm txias hauv cov txheej txheem.
Cov khoom siv txias txias ntawm Welser Profile's European qhov chaw tsis nyob ze li qhov muaj zog npaum li cov khoom siv muaj zog ntawm nws qhov chaw Superior, Ohio. Nyob ntawm daim ntawv thov, lub tuam txhab tuaj yeem tsim cov khoom txias txias ntawm qhov siab txog 450 MPa. Tab sis nws tsis yog tsuas yog xaiv cov khoom siv nrog lub zog tensile.
Johnson tau hais tias "Koj tsis tuaj yeem ua qhov ntawd nrog lub zog siab, cov khoom siv qis qis," Johnson hais ntxiv, "Peb feem ntau nyiam siv cov khoom siv micro-alloyed, uas pab tiv thaiv kev tawg. Pom tseeb, kev xaiv cov khoom siv yog ib feem tseem ceeb. "
Txhawm rau piav qhia txog lub hauv paus ntawm cov txheej txheem, Johnson piav qhia txog kev tsim lub raj telescoping. Ib lub raj yog ntxig rau hauv ib qho thiab tsis tuaj yeem tig, yog li txhua lub raj muaj ib qho ribbed zawj ntawm ib qho chaw nyob ib ncig ntawm lub voj voog. Cov no tsis yog stiffeners nrog radii xwb, lawv ua rau qee qhov kev sib hloov ua si thaum ib lub raj nkag mus rau lwm qhov. Cov kav dej nruj nruj no yuav tsum tau muab tso rau hauv thiab thim rov qab zoo nrog kev ua si me me. Tsis tas li ntawd, cov kab uas hla ntawm cov yeeb nkab sab nrauv yuav tsum yog tib yam, tsis muaj formwork protrusions ntawm lub puab kab. Txog rau qhov kawg no, cov hlab no muaj cov grooves tiag tiag uas thaum xub thawj siab ib muag zoo li extruded, tab sis lawv tsis yog. Lawv yog tsim los ntawm txias sib sau rau yob txoj kev tshuab.
Txhawm rau tsim cov grooves, cov cuab yeej dov thins cov khoom ntawm cov ntsiab lus tshwj xeeb raws qhov ncig ntawm cov yeeb nkab. Cov kws tsim qauv tsim cov txheej txheem kom lawv tuaj yeem kwv yees qhov tseeb ntawm cov khoom siv los ntawm cov "nyias" grooves mus rau seem ntawm cov yeeb nkab qhov ncig. Cov khoom ntws yuav tsum raug tswj xyuas kom meej kom ntseeg tau tias cov yeeb nkab phab ntsa tuab ntawm cov grooves. Yog tias cov yeeb nkab phab ntsa thickness tsis tas li, cov khoom yuav tsis zes kom zoo.
Cov txheej txheem txias txias ntawm Welser Profile's European rollforming nroj tsuag tso cai rau qee qhov chaw ua kom nyias, lwm tus tuab dua, thiab cov grooves yuav tsum tau muab tso rau hauv lwm qhov chaw.
Ib zaug ntxiv, tus kws ua haujlwm saib ntawm ib feem thiab yuav xav tias nws yog extrusion lossis kub forging, thiab qhov ntawd yog ib qho teeb meem nrog kev tsim technology uas tawm tsam cov kev txawj ntse. Ntau tus engineers tsis xav txog kev tsim ib feem, ntseeg tias nws yuav kim dhau lossis tsis tuaj yeem tsim khoom. Nyob rau hauv txoj kev no, Johnson thiab nws pab neeg tau tshaj tawm cov lus tsis yog tsuas yog hais txog lub peev xwm ntawm cov txheej txheem, tab sis kuj hais txog cov txiaj ntsig ntawm kev tau txais Welser Profile engineers koom nrog hauv profileing ntxov hauv cov txheej txheem tsim.
Tsim thiab yob engineers ua hauj lwm ua ke ntawm kev xaiv cov khoom siv, xaiv cov thickness thiab txhim kho cov qauv, ib nrab tsav los ntawm cov cuab yeej, thiab raws nraim qhov chaw txias txias (ie thickening thiab thinning) tshwm sim hauv paj tsim. ua tiav profile. Qhov no yog ib txoj haujlwm nyuaj dua li tsuas yog txuas cov qauv ntawm cov cuab yeej dov (Welser profile siv yuav luag cov cuab yeej modular nkaus xwb).
Nrog ntau tshaj 2,500 tus neeg ua haujlwm thiab ntau dua 90 yob txoj kab, Welser yog ib lub tsev neeg loj tshaj plaws uas muaj cov yob tsim cov tuam txhab hauv ntiaj teb, nrog cov neeg ua haujlwm loj rau cov cuab yeej thiab cov kws tsim khoom siv tib yam cuab yeej uas tau siv los txog tam sim no. tau ntau xyoo Die tsev qiv ntawv. Kev tshaj tawm ntau dua 22,500 qhov sib txawv.
Johnson tau hais tias "Tam sim no peb muaj ntau dua 700,000 [modular] cov cuab yeej rau cov menyuam hauv Tshuag," Johnson hais.
Johnson tau hais tias "Cov neeg tsim khoom tsis paub tias vim li cas peb thiaj li thov qee qhov tshwj xeeb, tab sis lawv tau ua raws li peb cov kev xav tau," Johnson tau hais, ntxiv tias cov "kev hloov pauv txawv txawv" ntawm cov nroj tsuag tau pab Welser txhim kho nws cov txheej txheem txias txias.
Yog li, Welzer tau ntev npaum li cas hauv kev lag luam steel? Johnson luag nyav. "Auj, yuav luag txhua lub sijhawm." Nws tsuas yog ib nrab tso dag xwb. Lub hauv paus ntawm lub tuam txhab hnub rov qab mus rau 1664. "Honestly, lub tuam txhab nyob rau hauv lub lag luam steel. Nws pib ua lub hauv paus thiab pib dov thiab tsim nyob rau hauv lig 1950s thiab tau loj hlob txij li thaum. "
Tsev neeg Welser tau khiav lag luam rau 11 tiam. Johnson tau hais tias "Tus thawj coj thawj coj yog Thomas Welser," Johnson tau hais. "Nws yawg tau pib lub tuam txhab profile thiab nws txiv yog ib tus neeg ua lag luam uas nthuav dav qhov loj thiab qhov kev lag luam." Niaj hnub no, cov nyiaj tau los txhua xyoo thoob ntiaj teb tau tshaj $ 700 lab.
Johnson tau hais ntxiv tias, “Thaum Thomas txiv tab tom tsim lub tuam txhab hauv Tebchaws Europe, Thomas tau dhau mus rau kev muag khoom thoob ntiaj teb thiab kev txhim kho kev lag luam. Nws xav tias qhov no yog nws tiam neeg thiab nws yog lub sijhawm rau nws coj lub tuam txhab thoob ntiaj teb. "
Kev nrhiav tau ntawm Superior yog ib feem ntawm lub tswv yim no, lwm qhov yog kev qhia txog kev siv tshuab txias txias rau Asmeskas. Thaum lub sijhawm sau ntawv, cov txheej txheem txias txias yuav tshwm sim ntawm Welser Profile cov chaw nyob sab Europe, los ntawm qhov chaw uas lub tuam txhab xa khoom mus rau lub ntiaj teb kev lag luam. Tsis muaj kev npaj yuav coj cov thev naus laus zis mus rau Asmeskas tau tshaj tawm, tsawg kawg tseem tsis tau. Johnson tau hais tias, zoo li txhua yam ntxiv, lub tshuab dov npaj yuav nthuav dav raws li qhov xav tau.
Cov qauv paj ntawm cov tsoos yob profile qhia cov theem ntawm cov khoom tsim thaum nws dhau los ntawm qhov chaw nres tsheb dov. Vim tias cov ntsiab lus tom qab Welser Profile txheej txheem txheej txheem txias yog tus tswv, nws tsis tsim cov qauv paj.
Welser Profile thiab nws cov chaw ua haujlwm Superior muab cov kev qhia ib txwm muaj, tab sis ob qho tib si tshwj xeeb hauv cov cheeb tsam uas tsis tas yuav tsum tau tshwj xeeb. Rau Superior, qhov no yog cov khoom siv muaj zog, rau Welser Profile, molding yog ib qho nyuaj uas feem ntau sib tw tsis yog nrog lwm lub tshuab dov, tab sis nrog extruders thiab lwm yam khoom siv tshwj xeeb.
Qhov tseeb, Johnson tau hais tias nws pab neeg tab tom nrhiav lub tswv yim aluminium extruder. "Thaum xyoo 1980s, cov tuam txhab txhuas tau tuaj rau hauv kev ua lag luam thiab hais tias, 'Yog tias koj ua npau suav nws, peb tuaj yeem nyem nws tawm.' Lawv tau zoo heev los muab cov kev xaiv rau engineers. Yog tias koj tuaj yeem npau suav txog nws, koj them tus nqi me me rau cov cuab yeej. Peb tuaj yeem tsim nws rau tus nqi. Qhov no tso tawm cov engineers vim tias lawv tuaj yeem kos txhua yam. Tam sim no peb tab tom ua qee yam zoo sib xws - tsuas yog tam sim no nrog profileing.
