Ndipotu, mbali imeneyi sikuwoneka ngati yopangidwa ndi zitsulo. Ma mbiri ena ali ndi mndandanda wa notch kapena grooves zomwe zimapangitsa kuti gawolo liwoneke ngati linali lotentha kapena lotuluka, koma sizili choncho. Uwu ndi mbiri yopangidwa pogwiritsa ntchito njira yozizira pamakina opangira mpukutu, ukadaulo womwe mabizinesi aku Europe a Welser Profile adapanga komanso kukhala ndi chilolezo ku US ndi mayiko ena. Anafunsira patent yake yoyamba mu 2007.
"Welser ali ndi ziphaso zokhutiritsa, zowonda komanso zozizira zomwe zimapanga ma profayilo," adatero Johnson. "Si makina, si thermoforming. Ndi anthu ochepa kwambiri ku US omwe amachita, kapena amayesa. ”
Popeza kufotokoza mbiri ndi ukadaulo wokhwima kwambiri, ambiri sayembekezera kuwona zodabwitsa m'derali. Ku FABTECH®, anthu akumwetulira ndikugwedeza mitu yawo akaona ma laser amphamvu kwambiri akudula mwachangu kwambiri kapena makina opindika okha omwe akuwongolera zolakwika. Ndi kupita patsogolo konse kwa matekinoloje opanga izi m'zaka zaposachedwa, iwo anali kuyembekezera zodabwitsa zodabwitsa. Sanayembekezere kupangidwa kwa mpukutu kudabwitsa iwo. Koma, monga mmene mainjiniya akuti “ndisonyezeni maluwa” akusonyezera, kufotokoza mbiri kumapitirirabe zimene amayembekezera.
Mu 2018, Welser adalowa mumsika waku US ndikupeza Superior Roll Forming ku Valley City, Ohio. Johnson adati kusunthaku ndikwanzeru, osati kungokulitsa kupezeka kwa Welser ku North America, komanso chifukwa Superior Roll Forming amagawana masomphenya ambiri achikhalidwe ndi njira za Welser.
Makampani onsewa akufuna kugonjetsa madera apadera amsika ozizira ndi opikisana nawo ochepa. Mabungwe onsewa akugwiranso ntchito kuti akwaniritse zosowa zamakampani zochepetsa kulemera. Magawo amayenera kuchita zambiri, kukhala amphamvu komanso ocheperako.
Superior imayang'ana gawo la magalimoto; pamene makampani onsewa amatumikira makasitomala osiyanasiyana, Welser imayang'ana kwambiri mafakitale ena monga zomangamanga, ulimi, dzuwa ndi shelving. Kulemera kopepuka mumsika wamagalimoto nthawi zonse kumangoyang'ana pa zida zamphamvu kwambiri, zomwe zilinso mwayi wa Superior. Ma geometry osavuta a mbiri yopindika samazindikirika mpaka mainjiniya awona kulimba kwa zinthu zopindika. Mainjiniya apamwamba nthawi zambiri amapanga mapulogalamu pogwiritsa ntchito zida zolimba za 1400 kapena 1700 MPa. Ndiye pafupifupi 250 KSI. Ku Ulaya, akatswiri a Welser Profile adakambirananso za kupepuka, koma kuwonjezera pa kugwiritsa ntchito zipangizo zamphamvu kwambiri, adayankhulanso ndi kuumba kovuta.
Njira zozizira zozizira za Welser Profile ndizoyenera zida zamphamvu zochepa, koma geometry yopangidwa ndi makina opangira mipukutu imathandizira kuchepetsa kulemera kwa msonkhano wonse. Ma geometry amatha kulola kuti mbiriyo igwire ntchito zingapo ndikuchepetsa kuchuluka kwa magawo (osatchulapo ndalama zomwe zimagwiritsidwa ntchito popanga). Mwachitsanzo, ma groove omwe ali ndi mbiri amatha kupanga zolumikizira zolumikizirana zomwe zimachotsa kuwotcherera kapena zomangira. Kapena mawonekedwe a mbiriyo angapangitse kuti dongosolo lonse likhale lolimba. Mwina chofunika kwambiri, Welser akhoza kupanga mbiri zomwe zimakhala zokhuthala m'malo ena ndi zowonda kwambiri mwa zina, kupereka mphamvu pamene zikufunikira ndikuchepetsa kulemera kwake.
Akatswiri opanga mapangidwe ndi okonza mapulani amatsatira ndondomeko ya zaka khumi: pewani ma radii ang'onoang'ono, nthambi zazifupi, zopindika za madigiri 90, ma geometries ozama mkati, ndi zina zotero. "Zoonadi, nthawi zonse tinali ndi zaka 90 zolimba," adatero Johnson.
Mbiriyi ikuwoneka ngati yotulutsa, koma imakhala yozizira kwambiri ndi Welser Profile.
Zachidziwikire, mainjiniya amafuna kuti makina opangira mipukutu aphwanye malamulo opangira izi, ndipo apa ndipamene luso la zida ndi uinjiniya wa malo ogulitsira amayambira. Mainjiniya ena atha kupititsa patsogolo ntchitoyi (kupanga 90-degree, ma geometries akuya mkati) pomwe akuchepetsa mtengo wa zida ndikusintha kusinthasintha, makina opangira ma roll adzakhala opikisana kwambiri.
Koma monga momwe Johnson akulongosolera, kuzizira kwa mphero kumakhala kokulirapo kuposa pamenepo. Izi zimakupatsani mwayi wopeza magawo omwe mainjiniya ambiri sangaganizire kugwiritsa ntchito mbiri. "Tangoganizani chingwe chachitsulo chomwe chadutsamo, mwina mainchesi 0.100 wokhuthala. Titha kupanga kagawo ka T pakatikati pa mbiriyi. iyenera kukhala yotentha kapena yopangidwa ndi makina kutengera kulekerera ndi zofunikira zina, koma titha kugubuduza geometry iyi."
Tsatanetsatane wa ndondomekoyi ndi katundu wa kampaniyo ndipo Welser sawulula zamaluwa. Koma Johnson akufotokoza zomveka za njira zingapo.
Choyamba, tiyeni tikambirane ntchito yosindikiza pa makina osindikizira. “Mukamapondereza, mumatambasulanso kapena kupondaponda. Chifukwa chake mumatambasula zinthuzo ndikuzisunthira kumadera osiyanasiyana a chida [pamwamba], monga momwe mumadzaza radii pa chida. Koma [polemba mbiri] Kupanga kozizira kumeneku] kuli ngati kudzaza ma radii pa ma steroid.”
Kugwira ntchito kozizira kumalimbitsa zinthu m'malo ena, izi zitha kupangidwa kuti zipindule ndi wopanga. Komabe, makina opanga mbiri akuyeneranso kuganizira zosintha izi pazinthu zakuthupi. "Mutha kuwona kuwonjezeka kwakukulu kwa magwiridwe antchito, nthawi zina mpaka 30 peresenti," akutero Johnson, ndikuwonjezera kuti chiwonjezekochi chiyenera kukhazikitsidwa muzogwiritsira ntchito kuyambira pachiyambi.
Komabe, kuzizira kwa Welser Profile kungaphatikizepo ntchito zina monga kusoka ndi kuwotcherera. Monga momwe zimakhalira ndi mbiri yanthawi zonse, kuboola kutha kuchitika musanayambe, panthawi, kapena mutatha kujambula, koma zida zomwe zimagwiritsidwa ntchito ziyenera kuganizira zotsatira za ntchito yozizira panthawi yonseyi.
Zinthu zoziziritsa kukhosi ku Welser Profile's European station sizili pafupi ndi mphamvu ngati zida zamphamvu zokulungidwa pamalo ake a Superior, Ohio. Kutengera kugwiritsa ntchito, kampaniyo imatha kupanga zinthu zoziziritsa kukhosi mpaka 450 MPa. Koma sikuti kungosankha chinthu chokhala ndi mphamvu zolimba.
"Simungathe kuchita zimenezi ndi zipangizo zamphamvu kwambiri, zotsika kwambiri," anatero Johnson, akuwonjezera kuti, "Nthawi zambiri timakonda kugwiritsa ntchito zipangizo zamagetsi, zomwe zimathandiza kupewa kusweka. Mwachionekere, kusankha zinthu zakuthupi n’kofunika kwambiri.”
Kuti afotokoze zofunikira za ndondomekoyi, Johnson akufotokoza mapangidwe a chubu cha telescoping. Chubu chimodzi chimayikidwa mkati mwa chinzake ndipo sichingazungulire, motero chubu chilichonse chimakhala ndi nthiti pamalo enaake mozungulira mozungulira. Izi sizimangokhala zowumitsa zokhala ndi ma radii, zimayambitsa kusewera kozungulira pomwe chubu limodzi lilowa lina. Machubu olimba olimba awa amayenera kulowetsedwa molondola ndikubwezedwa bwino ndikusewera pang'ono mozungulira. Komanso, m'mimba mwake akunja chitoliro ayenera kukhala chimodzimodzi, popanda formwork protrusions pa m'mimba mwake wamkati. Kuti izi zitheke, machubuwa ali ndi mikwingwirima yeniyeni yomwe poyang'ana koyamba imawoneka ngati yatuluka, koma siili. Iwo amapangidwa ndi ozizira kupanga pa mpukutu kupanga makina.
Kuti apange grooves, chida chogudubuzacho chimachepetsetsa zinthuzo pamalo enaake mozungulira chitoliro. Akatswiriwa anakonza njirayo n’cholinga choti athe kudziwa bwinobwino mmene zinthu zidzayendera kuchokera m’tipaipi “zoonda” n’kupita ku mbali ina yonse ya chitolirocho. Kuthamanga kwa zinthu kuyenera kuyendetsedwa bwino kuti kuwonetsetse kuti makulidwe a chitoliro pakati pa ma groove awa. Ngati makulidwe a khoma la chitoliro siwokhazikika, zigawozo sizikhala bwino.
Kuzizira kopanga zomera ku Welser Profile's European rollforming kumapangitsa kuti mbali zina zikhale zoonda, zina zokhuthala, ndikuyika ma groove m'malo ena.
Apanso, mainjiniya amayang'ana mbali ina ndipo amatha kuganiza kuti ndi yakunja kapena yowotcha, ndipo ndizovuta ndiukadaulo uliwonse wopanga zomwe zimatsutsana ndi nzeru wamba. Mainjiniya ambiri sanaganizire kupanga mbali yoteroyo, pokhulupirira kuti ikakhala yokwera mtengo kwambiri kapena yosatheka kupanga. Mwanjira imeneyi, Johnson ndi gulu lake akufalitsa mawu osati za luso la ndondomekoyi, komanso za ubwino wopeza akatswiri a Welser Profile akutenga nawo mbali pakupanga mbiri yoyambirira.
Akatswiri okonza mapulani amagwirira ntchito limodzi posankha zinthu, kusankha mwanzeru makulidwe ndi kukonza mbewu, zomwe zimayendetsedwa ndi zida, komanso komwe kuzizira (ie kukhuthala ndi kupatulira) kumachitika popanga maluwa. mbiri yonse. Iyi ndi ntchito yovuta kwambiri kuposa kungolumikiza magawo osinthika a chida chogubuduza (mbiri ya Welser imagwiritsa ntchito zida zosinthira zokha).
Ndi antchito opitilira 2,500 komanso mizere yopitilira 90, Welser ndi imodzi mwamakampani akulu kwambiri padziko lonse lapansi omwe ali ndi mabanja, omwe ali ndi antchito ambiri odzipereka ku zida ndi mainjiniya omwe amagwiritsa ntchito zida zomwe zakhala zikugwiritsidwa ntchito mpaka pano. kwa zaka zambiri Die library. Kujambula pamitundu yopitilira 22,500.
"Pakadali pano tili ndi zida zopitilira 700,000 [modular] zomwe zili," adatero Johnson.
"Omanga nyumbayi sankadziwa chifukwa chake tinkapempha kuti tidziwe zambiri, koma anakwaniritsa zofunikira zathu," anatero Johnson, akuwonjezera kuti "kusintha kwachilendo" kumeneku kunathandiza Welser kukonza njira yake yozizira.
Ndiye, Welzer wakhala nthawi yayitali bwanji mubizinesi yazitsulo? Johnson anamwetulira. "O, pafupifupi nthawi zonse." Anangochita nthabwala chabe. Maziko a kampaniyi anayamba m’chaka cha 1664. “Kunena zoona, kampaniyi imachita bizinesi yazitsulo. Idayamba ngati poyambira ndipo idayamba kugundika kumapeto kwa zaka za m'ma 1950 ndipo yakhala ikukula kuyambira pamenepo. ”
Banja la a Welser layendetsa bizinesiyo kwa mibadwo 11. "Mkulu wamkulu ndi a Thomas Welser," Johnson adatero. "Agogo ake aamuna adayambitsa kampani yopanga mbiri ndipo abambo ake anali abizinesi omwe amakulitsa kukula ndi kukula kwa bizinesiyo." Masiku ano, ndalama zomwe amapeza pachaka padziko lonse lapansi zimaposa $700 miliyoni.
Johnson anapitiriza kuti, “Pamene bambo ake a Thomas ankamanga kampaniyo ku Ulaya, Thomas analidi wochita malonda padziko lonse ndi chitukuko cha bizinesi. Akuwona ngati uwu ndi m'badwo wake ndipo ndi nthawi yoti atenge kampani padziko lonse lapansi. "
Kupeza kwa Superior kunali gawo la njira iyi, gawo lina linali kuyambitsa ukadaulo wozizira wozizira ku US. Panthawi yolemba, kuzizira kozizira kumachitika ku Welser Profile ku Europe, komwe kampaniyo imatumiza zinthu kumisika yapadziko lonse lapansi. Palibe mapulani obweretsa ukadaulo ku US adalengezedwa, osachepera. Johnson adati, monga china chilichonse, mpheroyo ikukonzekera kukulitsa mphamvu potengera zomwe akufuna.
Mtundu wamaluwa wamtundu wa mpukutu wachikhalidwe ukuwonetsa magawo a mapangidwe azinthu akamadutsa pozungulira. Chifukwa tsatanetsatane wa kuzizira kwa Welser Profile ndi eni ake, sizimapanga maluwa.
Mbiri ya Welser ndi othandizira ake a Superior amapereka mbiri yakale, koma onse amakhazikika m'malo omwe safunikira. Kwa Superior, ichi ndi chinthu champhamvu kwambiri, kwa Welser Profile, kuumba ndi mawonekedwe ovuta omwe nthawi zambiri amapikisana osati ndi makina ena ogubuduza, koma ndi extruders ndi zipangizo zina zapadera zopangira.
M'malo mwake, Johnson adati gulu lake likutsata njira ya aluminium extruder. "Kumayambiriro kwa zaka za m'ma 1980, makampani a aluminiyamu anabwera kumsika nati, 'Ngati mungathe kulota, tikhoza kuzifinya.' Iwo anali abwino kwambiri popatsa mainjiniya zosankha. Ngati mungathe kulota za izo, mumalipira ndalama zochepa pazida. Tikhoza kuzipanga pamtengo. Izi zimamasula mainjiniya chifukwa amatha kujambula chilichonse. Tsopano tikuchita zofanana - pokha pokha polemba mbiri.
Tim Heston ndi Mkonzi Wamkulu wa FABRICATOR Magazine ndipo wakhala ali mu makampani opanga zitsulo kuyambira 1998, kuyamba ntchito yake ndi American Welding Society's Welding Magazine. Kuyambira nthawi imeneyo, wakhala akugwira ntchito yonse yopangira zitsulo, kuyambira kupondaponda, kupindika ndi kudula mpaka kugaya ndi kupukuta. Adalowa nawo The FABRICATOR mu Okutobala 2007.
FABRICATOR ndiye magazini otsogola kwambiri osindikizira ndi kupanga zitsulo ku North America. Magaziniyi imasindikiza nkhani, zolemba zamakono ndi nkhani zopambana zomwe zimathandiza opanga kupanga ntchito yawo bwino. FABRICATOR wakhala akugulitsa kuyambira 1970.
