Mawu akuti hemming adachokera pakupanga nsalu pomwe m'mphepete mwa nsalu amapindikanso payokha ndiyeno amasokedwa.Mu pepala zitsulo hemming amatanthauza kuti pindani chitsulo kumbuyo chokha.Mukamagwira ntchito ndi Brake Press hems nthawi zonse amapangidwa munjira ziwiri:
Pangani bend ndi Acute Angle Tooling muzitsulo, 30 ° ndi yabwino koma 45 ° idzagwira ntchito nthawi zina.
Ikani kupindika kwakukulu pansi pa kapamwamba ndikuyikani mphamvu zokwanira kuti mumalize kutseka.
Gawo loyamba limapangidwa mofanana ndi bend iliyonse yokhazikika yokhazikika.Gawo lachiwiri la ndondomeko ya hemming limafuna zina zowonjezera kudziwa momwe pa mbali ya Brake Press operator ndi wopanga zida chifukwa ngodya ya pepala zitsulo, kapamwamba kapamwamba kakufuna kutsika ndi kuchoka pazitsulo zachitsulo.Kuphatikiza apo, ntchitoyo ikufuna kutsika kuchokera pakati pa mipiringidzo.Mphamvu ziwirizi zimadziwika kuti thrust forces.
Chithunzi cha Mphamvu Zopondereza Kuchokera ku Hemming Sheet Metal
Izi zimafuna kuti chophwanyikacho chipangidwe kuti chizitha kupirira ndikukhalabe osasunthika.Kuphatikiza apo, pamafunika kuti woyendetsayo ayike mphamvu yakutsogolo motsutsana ndi chitsulo chachitsulo kuti zisatuluke pakufa.Mphamvu izi zimawonekera kwambiri pazidutswa zokhuthala ndi ma flange amfupi.Poganizira izi, tiyeni tiwone mitundu itatu yodziwika bwino ya ma hemming seti ndi zida zomwe zilipo pamabuleki atolankhani.
Multi Tool Setup, Acute Tooling ndi Flattening Die
Njira yosavuta kwambiri yopangira hemming ndikuphatikiza magawo awiri osiyana.Yoyamba ndikukhazikitsa mwamphamvu, pomwe kupindika kwa 30 ° kumapangidwa pogwiritsa ntchito zida zokhazikika.Mukapindika koyamba, gawolo limasamutsidwa ku makina ena, kapena kukhazikitsidwa kwatsopano kumayikidwa mu choyambirira.Kukonzekera kwachiwiri ndi kapamwamba kophweka.Kupindika kumayikidwa pansi pa bar flattening ndipo kutsekedwa.Kukonzekera uku sikufuna zida zapadera ndipo kutha kukhala koyenera pamayendedwe amfupi, ma prototypes kapena malo ogulitsa ntchito omwe angafunike kupanga utali wosiyanasiyana.Monga zidutswa za Brake Press Tooling chida chokhazikika komanso chosalala chimakhala chosunthika, ndikuwonjezera phindu kunja kwa hemming.Zomwe zimabwerera ku dongosololi ndizofunikira zodziwikiratu zamakhazikitsidwe awiri apadera, komanso palibe kuwongolera pakuwongolera.
Magawo Awiri a Hemming Punch ndi Die Combination
Magawo awiri a hemming die amagwira ntchito pogwiritsa ntchito kufa kozama komanso nkhonya ya lupanga.Kupindika koyamba kumagwiritsa ntchito tchanelo ngati kutsegulira kwa mpweya kuti apange kupindika.Mu gawo lachiwiri nkhonya imalowa mumsewu pamene nkhonya imatsekedwa ndipo m'mphepete mwa nkhonya imagwiritsidwa ntchito kuphwanyitsa chitsulo.Kuyika nkhonya mkati mwa njira ya kufa kumawongoleranso mphamvu yokankhira mu kufa, yomwe imatha kutetezedwa mosavuta kuposa nkhonyayo.The drawback kwa mtundu uwu wa kufa ndi kuti amafuna pafupifupi CNC ulamuliro.Chifukwa cha kusiyana kwa msinkhu pakati pa sitiroko ya gawo loyamba ndi lachiwiri kusintha pamanja kungakhale nthawi yambiri.Kuphatikiza apo, mtundu uwu wa kufa ukhoza kugawanika mosavuta kuchokera ku tonnage, kulimbitsa kufunikira kwa chitetezo choyendetsedwa ndi makompyuta.
Magawo Atatu Hemming Khofi Ndikufa
Njira ina yodziwika bwino yopangira zida zopangira ma hems ndi magawo atatu, kapena nkhonya yamtundu wa accordion ndi kufa.Kutsegula kwa v kumakhala pamwamba pa kasupe wodzaza kasupe, komwe kumakhala pansi.Mu gawo loyamba kupindika kwakukulu kumapangidwa pakutsegula kwa v pambuyo poti kasupe watsindikiridwa ndipo pad yapamwamba imakhala pamunsi wapansi.Mu gawo lachiwiri nkhosa yamphongo yakumtunda imachotsedwa ndipo akasupe apakati pa thayo lapamwamba ndi lapansi amaibwezera pamalo ake oyambirira.Chitsulocho chimayikidwa pakati pa chitsulo chapamwamba ndi chapansi ndipo nkhonya imatsekedwa kusuntha matani kudzera mu v kufa.Thandizo lapadera limaperekedwa kwa v kufa kulola chida ichi pakugwiritsa ntchito chida.Kalozera pakati pa pad chapamwamba ndi m'munsi amalepheretsa kukankhira mphamvu kukhudza zida zonse.Chotsitsa cham'munsichi chimapatsanso wogwiritsa ntchito chinthu chothandizira kuti zitsulo zisatuluke.Chida ichi chimakondedwa pamakina, omwe si CNC, mabuleki chifukwa kusiyana kwa kutalika kwa sitiroko kumakhala kochepa kwambiri, zomwe zimapangitsa kuti kusintha kusakhale nthawi yambiri.Kukhazikitsa uku kumakupatsaninso mwayi wogwiritsa ntchito nkhonya yokhazikika.
Tonnage Yofunikira Pa Kuyimitsa
Matani ofunikira pakumangirira adzadalira mphamvu ya zinthu zanu, makulidwe ake komanso makamaka mtundu wa hem yomwe mukufuna kupanga.Kugwetsa misozi ndi kutseguka m'mphepete sikufuna matani ochuluka monga momwe m'mphepete mwake amachitira.Izi ndichifukwa choti mukungosintha utali wamkati pang'ono, kwenikweni mukungopitirira 30 °.Mukapalasa chitsulocho, mukupanga chikwanje ndikuchotsa utali wamkati.Tsopano mukupanga chitsulocho m’malo mongochipinda.Pansipa mutha kuwona tchati cha hemming tonnage chachitsulo chozizira.
Zogwiritsidwa Ntchito Kwa Hems
Mahemu nthawi zambiri amagwiritsidwa ntchito kukakamizanso, kubisala zolakwika komanso kupereka m'mphepete mwachitetezo kuti mugwire.Pamene mapangidwe amafuna chitetezo, ngakhale m'mphepete mtengo wowonjezera wa zinthu ndi kukonza m'mphepete nthawi zambiri zimakhala zabwino kuposa njira zina zochizira m'mphepete.Okonza ayenera kuyang'ana kupyola kagawo kakang'ono kakang'ono kakang'ono kuti athetse m'mphepete.Kuwirikiza mpendero kungapangitse m'mphepete mwabwino kuti mugwire ntchito mosaganizira mtundu woyamba wa m'mphepete.Kuonjezera hem mu 'pakati' pa bend mbiri akhoza kutsegula zitseko zosiyanasiyana mbiri zosatheka popanda fasteners kapena kuwotcherera.Ngakhale popanda makina osokera amakono kuphatikiza mipendero iwiri imatha kupanga zolumikizana zolimba, zolimba zomangika pang'ono kapena zochepa.Mahemu amatha kugwiritsidwa ntchito kuwirikiza kawiri makulidwe achitsulo m'malo a gawo lomwe lingafunike chithandizo chowonjezera.Mahemu omwe amagwiritsidwa ntchito m'makampani ogulitsa chakudya ayenera kukhala otsekedwa nthawi zonse kuti akhale aukhondo (ovuta kwambiri kuyeretsa mkati mwa kutsegula).
