Pakuchulukirachulukira kwazinthu zapamwamba komanso zotetezeka, hemming sheet metal ikukhala yofala kwambiri pama brake atolankhani.Ndipo ndi njira zambiri zothanirana ndi ma brake hemming pamsika, kudziwa yankho lomwe lili loyenera ntchito zanu zitha kukhala projekiti yokha.
Werengani pansipa kuti mudziwe zambiri za mitundu yosiyanasiyana ya zida za hemming, kapena onani mndandanda wathu wa Hemming ndikulandila upangiri waukadaulo pa chida chabwino kwambiri cha hemming pazosowa zanu!
Onani Hemming Series
Kodi sheet metal hemming ndi chiyani?
Monga momwe mumapangira zovala ndi kusoka bizinesi, hemming sheet chitsulo imaphatikizapo kupukutira chinthu chimodzi pamwamba pa chinzake kuti apange m'mphepete lofewa kapena lozungulira.Amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza firiji, kupanga makabati, kupanga zida zamaofesi, zida zopangira chakudya, ndi zida zosungiramo zinthu zakale ndi zosungirako kungotchulapo zochepa chabe.
M'mbiri, hemming nthawi zambiri imagwiritsidwa ntchito pazinthu zoyambira 20 ga.ku 16 ga.zitsulo zofatsa.Komabe, ndi kusintha kwaposachedwa kwaukadaulo wopezeka wa hemming sizachilendo kuwona hemming ikuchitika pa 12 - 14 ga., Ndipo nthawi zina ngakhale wandiweyani ngati 8 ga.zakuthupi.
Zopangira zitsulo za Hemming zimatha kukongoletsa kukongola, kuchotseratu mawonekedwe akuthwa m'mbali ndi ma burrs m'malo omwe gawolo lingakhale lowopsa kugwiridwa, ndikuwonjezera mphamvu ku gawo lomwe lamalizidwa.Kusankha zida zoyenera zomangira zimatengera momwe mungakhalire mozungulira pafupipafupi komanso makulidwe azinthu omwe mukufuna kuwazungulira.
Hammer Toolshammer-chida-punch-ndi-die-hemming-process
Max.makulidwe azinthu: 14 gauge
Ntchito Yabwino: Yabwino kwambiri ngati hemming imachitika pafupipafupi komanso mosiyanasiyana pakukhuthala kwazinthu.
Kupindika Kwapadziko Lonse: Ayi
Zida za hammer ndi njira yakale kwambiri yopangira hemming.Mwanjira iyi, m'mphepete mwa zinthuzo amapindika ndi zida zapang'onopang'ono mpaka kuphatikizikako pafupifupi 30 °.Pa opareshoni yachiwiri, flange yopindika isanakwane imaphwanyidwa pansi pa zida zosalala, zomwe zimakhala ndi nkhonya ndikufa ndi nkhope zosalala kuti zipange mkombero.Chifukwa ndondomekoyi imafuna zida ziwiri zopangira zida, zida za nyundo zimasungidwa bwino ngati njira yabwino yopangira ndalama zopangira ma hemming osakhazikika.
Max.makulidwe azinthu: 16 gauge
Kugwiritsa Ntchito Bwino: Zabwino kwambiri pakumangirira kwa zinthu zoonda mwa apo ndi apo.Oyenera "ophwanyidwa" m'mphepete.
Kupinda konsekonse: Inde, koma ndi malire.
Kuphatikizika kwa nkhonya ndi kufa (kapena kumwalira kwa mawonekedwe a U) kumagwiritsa ntchito nkhonya yolimba ya 30 ° yokhala ndi nsagwada yosalala kutsogolo ndi kufa kooneka ngati U komwe kumakhala kosalala pamwamba.Mofanana ndi njira zonse zokhotakhota, kupindika koyamba kumaphatikizapo kupanga 30ۡ ° pre-bend.Izi zimatheka ndi nkhonya yoyendetsa zinthuzo potsegula ngati U-pakufa.Zinthuzo zimayikidwa pamwamba pa ufa ndi flange yopindika ikuyang'ana mmwamba.Chikhomerocho chimayendetsedwanso pansi kulowa mumsewu wooneka ngati U pa kufa pomwe nsagwada yosalala pa nkhonya imadutsa pagawo losalala.
Chifukwa chakuti hemming yopangidwa ndi U imakhala ndi khoma lolimba lachitsulo pansi pa malo omwe ntchito yowonongeka imachitika, mphamvu yolemetsa yoperekedwa ndi mapangidwe awa imagwira ntchito bwino popanga "zophwanyidwa".Chifukwa chogwiritsa ntchito nkhonya yamphamvu yopindika isanakwane, kufa kwa mawonekedwe a U kutha kugwiritsidwanso ntchito popinda konsekonse.
Kugwirizana kwa mapangidwe awa ndikuti nsagwada yosalala ili kutsogolo kwa nkhonya, iyenera kukhala yozama mozama kuti isasokoneze zakuthupi pamene ikukwera m'mwamba kuti ipange 30-degree pre-bend.Kuzama kozama kumeneku kumapangitsa kuti zinthuzo zizitha kutuluka munsagwada yosalala, zomwe zimatha kuwononga zala zakumbuyo za brake.Nthawi zambiri, izi ziyenera kukhala nkhani pokhapokha ngati zinthuzo zili ndi zitsulo zokhala ndi malasha, zili ndi mafuta aliwonse pamwamba, kapena ngati flange yomwe idapindika ikhala yopindika pamakona ophatikizidwa omwe ndi akulu (otseguka) kuposa 30 °.
Magawo awiri a hemming amafa (odzaza masika) -njira yodzaza masika
Max.makulidwe azinthu: 14 gauge
Kugwiritsa Ntchito Bwino: Kwa ma hemming osakhazikika kapena ochepera a makulidwe osiyanasiyana azinthu.
Kupindika Kwapadziko Lonse: Inde
Pamene mabuleki osindikizira ndi mapulogalamu akuwonjezeka, magawo awiri a hemming amafa adakhala otchuka kwambiri.Mukamagwiritsa ntchito izi zikafa, gawolo limapindika ndi nkhonya ya 30 ° yolimba kwambiri ndipo hemming kufa ndi 30 ° pachimake ngodya V-kutsegula.Zigawo zam'mwamba za imfazi zimadzazidwa ndi kasupe ndipo panthawi yokhazikika, zinthu zomwe zimapindika zimayikidwa pakati pa nsagwada zosalala kutsogolo kwa ufa ndipo nsagwada yapamwamba imayendetsedwa pansi ndi nkhonya panthawi ya kugunda kwa nkhonya. Ram.Izi zikachitika, flange yomwe idapindika kale imaphwanyidwa mpaka nsonga yotsogola ikukhudzana ndi pepala lathyathyathya.
Ngakhale kuti imakhala yofulumira komanso yopindulitsa kwambiri, magawo awiri a hemming dies ali ndi zovuta zake.Chifukwa amagwiritsa ntchito kasupe wodzaza pamwamba, ayenera kukhala ndi mphamvu yokwanira ya masika kuti agwire pepala popanda kugwetsa ngakhale pang'ono mpaka kupindika koyamba kuyambika.Ngati alephera kutero, chinthucho chikhoza kulowa pansi pa zala zakumbuyo ndikuziwononga pamene kupindika koyamba kumapangidwa.Kuphatikiza apo, amafunikira V-kutsegula komwe kuli kofanana ndi makulidwe azinthu kasanu ndi kamodzi (mwachitsanzo, pazinthu zokhala ndi makulidwe a 2mm, masika odzaza hemming amafa amafunikira 12mm v-kutsegula).
Matebulo opindika achi Dutch / matebulo a hemming
Max.makulidwe azinthu: 12 gauge
Kugwiritsa Ntchito Bwino: Ndikoyenera kuti muzichita ma hemming pafupipafupi.
Kupindika Kwapadziko Lonse: Inde.Njira yosunthika kwambiri pa hemming ndi kupindika konsekonse.
Mosakayikira, kupita patsogolo kwamakono komanso kopindulitsa kwambiri kwa zida za hemming ndi "gome lachi Dutch," lomwe limatchedwanso "tebulo la hemming."Mofanana ndi hemming yodzaza kasupe ikafa, matebulo opindika achi Dutch amakhala ndi nsagwada zosalala kutsogolo.Komabe, mosiyana ndi hemming yodzaza kasupe ikafa, nsagwada zosalala pa tebulo lopindika la Dutch zimayendetsedwa ndi masilinda a hydraulic.Ma hydraulic cylinders amapangitsa kuti zitheke kubisa makulidwe ndi zolemetsa zosiyanasiyana chifukwa vuto la kupanikizika kwa masika limathetsedwa.
Kuwirikiza ngati chogwirizira, matebulo opindika achi Dutch amakhalanso ndi kuthekera kosinthana kufa kwa digirii 30, zomwe zimathandiziranso kuti athe kumiza makulidwe osiyanasiyana azinthu.Izi zimawapangitsa kukhala osinthasintha kwambiri ndipo kumabweretsa kuchepa kwakukulu kwa nthawi yokhazikitsa.Kukhala ndi mphamvu yosinthira v-kutsegula, kuphatikizapo luso logwiritsa ntchito ma hydraulic cylinders kuti atseke nsagwada za flattening kumapangitsanso kugwiritsa ntchito dongosolo ngati chosungira imfa pamene sichikugwiritsidwa ntchito popanga hemming.
Zipangizo zokhuthala Kusuntha-kupalasa-pansi-chida-ndi-zodzigudubuza
Ngati mukuyang'ana kuti muchepetse zida zokulirapo kuposa 12 ga., mufunika chida chosunthira pansi.Chida chosunthika chapansi chimalowa m'malo mwa chida chokhazikika pansi chomwe chimagwiritsidwa ntchito popanga zida za nyundo ndi kufa komwe kumakhala ndi zodzigudubuza, zomwe zimalola chida kuti chizitha kuyamwa katundu wam'mbali wopangidwa pokhazikitsa chida cha nyundo.Potengera katundu wam'mbali chida chapansi chosuntha chimalola kuti zinthu zikhale zokhuthala ngati 8 ga.kuti atsekeredwe pa press brake.Ngati mukuyang'ana kuti muchepetse zida zokulirapo kuposa 12 ga., iyi ndiye njira yokhayo yovomerezeka.
Pamapeto pake, palibe chida cha hemming chomwe chili choyenera ntchito zonse za hemming.Kusankha chida choyenera cha brake hemming kumatengera zida zomwe mukufuna kupindika komanso momwe mungakhalire mozungulira.Ganizirani zamtundu wa geji yomwe mukufuna kupindika, komanso kuchuluka kwa ma seti omwe adzafunikire kuti mumalize ntchito zonse zofunika.Ngati simukutsimikiza kuti ndi njira iti ya hemming yomwe ili yabwino kwambiri pamachitidwe anu, funsani wogulitsa zida zanu kapena WILA USA kuti mukambirane zaulere.
