Ntchito zina zovuta zopindika zingawononge pamwamba pa chubu. Zipangizo ndi zitsulo, mapaipi ndi zitsulo, ndipo nthawi zina kusweka kapena kukanda sikungapeweke. Getty Images
Kupinda bwino kumakhala kosavuta pa ntchito zambiri zopangira machubu, makamaka pogwiritsa ntchito ma rotary stretch benders aposachedwa. Zida zonse - ma bend dies, ma wiper dies, ma clamping dies, ma pressure dies ndi mandrels - zimazungulira ndikutseka chubucho mkati ndi kunja kuti chitsulo chiziyenda komwe chikuyenera kuyenda panthawi yopinda. Izi, kuphatikiza ndi njira yamakono yowongolera, zimapereka zotsatira zabwino kwambiri pamapindo osavuta komanso ocheperako. Sizopanda pake, chifukwa kupambana kumafunanso kukhazikitsidwa bwino ndi mafuta, koma nthawi zambiri zotsatira zake zimakhala mapindo abwino, nthawi ndi nthawi, tsiku ndi tsiku.
Akakumana ndi mapindidwe ovuta, opanga ali ndi njira zingapo. Makina ena ozungulira ojambula mawaya ali ndi ntchito yokweza mabulaketi yomwe imapereka mphamvu yokankhira kuti ithandize mphamvu yokoka mawaya. Kuphatikiza pa izi, opanga zida nthawi zambiri amakhala ndi njira imodzi kapena ziwiri zothetsera mapindidwe ovuta, monga kuwonjezera kutalika kwa chogwirira kapena kupangira mapindidwe angapo pamwamba pa chogwirira. Ma clamp ataliatali amapanga kukangana kwambiri; mapindidwewo amaluma pamwamba pa chubu. Zonsezi zimapereka kugwira kowonjezera kuti chubucho chisagwedezeke panthawi yopindika.
Mosasamala kanthu za mfundo zenizeni, cholinga chake ndi kupanga zinthu zomwe zikugwirizana ndi zosowa za makasitomala. Nthawi zambiri, izi zikutanthauza kuti zinthuzo sizisintha kwenikweni komanso kuti pamwamba pake pasakhale chosalala. Komabe, izi sizimavala chitsulo. Kwa machubu obisika kuti asawonekere, makasitomala amatha kulekerera kupendekera kwakukulu pamachubu ozungulira, kupendekeka kwakukulu kwa machubu a sikweya kapena amakona anayi, makwinya pang'ono mpaka pang'ono kapena zizindikiro zogwirira mkati mwa kupindika. Zambiri mwa izi zitha kuwerengedwa ngati kusiyana kwa peresenti kuchokera ku kupindika koyenera, kotero ndikofunikira kudziwa zomwe kasitomala akufunadi. Anthu ena ali okonzeka kulipira ndalama zambiri kuti apike koyambirira, pomwe ena amakonda kupindika kotsika mtengo kwambiri komwe kuli ndi zolakwika zoonekeratu.
Nthawi zina makasitomala amasankha chigongono chomwe sichikuwoneka chovuta kupanga, chimapangidwa ndi nsalu yofewa pang'ono yokhala ndi makulidwe a khoma okwanira kutambasula kunja kwa chigongono popanda kugawanika, koma osati kwambiri kuti chigwirizane mkati mwa kupindika. Poyamba chimawoneka ngati kupindika kosavuta, koma kasitomala adavumbulutsa mfundo yomaliza: palibe zizindikiro. Pulogalamuyi ndi yokongola, kotero makasitomala sangalole kuwonongeka kulikonse kuchokera ku chidacho.
Ngati kupindika kwa mayeso kumabweretsa zizindikiro za makina, wopanga ali ndi njira ziwiri. Choyamba ndikutenga njira yowonjezera yopukuta chinthu chomalizidwa kuti achotse zizindikiro zonse za zida. Zachidziwikire, kupukuta kumatha kukhala kopambana, koma kumatanthauza kugwiritsa ntchito kowonjezera komanso kugwira ntchito yambiri, kotero sikuti nthawi zonse kumakhala kotsika mtengo.
Kuchotsa kuwonongeka ndi nkhani yochotsa pamwamba pa chida chachitsulo. Izi zimachitika popanga zida kuchokera ku ma polima opangidwa ndi zinthu zolemera kapena kupanga zida zoyikamo zinthu kuchokera ku zipangizozi.
Njira zonsezi ndi zosiyana ndi miyambo; zida zopindika nthawi zambiri zimapangidwa ndi zitsulo zokha. Zipangizo zina zochepa zimatha kupirira mphamvu zopindika ndikupanga chubu kapena chitoliro, ndipo nthawi zambiri sizimakhala zolimba kwambiri. Komabe, awiri mwa mapulasitiki awa akhala zinthu zodziwika bwino pakugwiritsa ntchito izi: Derlin ndi Nylatron. Ngakhale kuti zipangizozi zili ndi mphamvu zopondereza bwino, sizolimba ngati chitsulo cha zida, ndichifukwa chake sizisiya zizindikiro. Zilinso ndi mafuta achilengedwe. Chifukwa cha zinthu ziwirizi, zida zowononga nthawi zambiri sizimalowa m'malo mwa zida wamba.
Popeza ma polymer molds sapanga mphamvu zokangana monga momwe ma steel molds amachitira, zigawo zomwe zimatuluka nthawi zambiri zimafuna ma radii akuluakulu opindika ndipo zimapangidwa kuti zithandizire ma clamp ataliatali kuposa mapangidwe a chitsulo mold. Mafuta odzola amafunikirabe, ngakhale nthawi zambiri amakhala ochepa. Mafuta odzola ochokera m'madzi ndiye chisankho chabwino kwambiri chopewera kusintha kwa mankhwala pakati pa mafuta odzola ndi chida.
Ngakhale zida zonse zimakhala ndi nthawi yochepa yogwira ntchito, zida zopanda kuwonongeka zimakhala ndi nthawi yochepa yogwira ntchito kuposa zida zachikhalidwe. Ichi ndi chinthu chofunikira kuganizira potchula mtundu uwu wa ntchito, chifukwa zida ziyenera kusinthidwa pafupipafupi. Kuchuluka kumeneku kungachepe pogwiritsa ntchito zida za polima zolumikizidwa ku zida zachitsulo zokhala ndi zomangira zamakaniko, zomwe nthawi zambiri zimakhala nthawi yayitali kuposa zida zopangidwa ndi polima yokha.
Zinyalala zopanda kuwonongeka ndizoyenera kupanga chitsulo, chitsulo chosapanga dzimbiri, aluminiyamu ndi mkuwa, ndipo ntchito zambiri zimasiyana malinga ndi zinthu. Zakudya ndi zakumwa ndizoyenera kugwiritsa ntchito pazida zopanda kuwonongeka. Chabwino kwambiri, mapaipi opangira chakudya kapena zakumwa ndi osalala kwambiri. Zilonda zilizonse, mabala kapena mikwingwirima yotsala pamwamba pa chitoliro kapena chitoliro zimatha kusonkhanitsa zinyalala ndikukhala malo oberekera mabakiteriya.
Ntchito zina zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo ziwalo zophimbidwa kapena zophimbidwa. Lingaliro lolakwika lomwe anthu ambiri amalipeza ndilakuti njira yophimbira kapena yophimbira ndi yamagetsi imadzaza kapena kubisa zolakwika. Zophimbira ndi zophimbira ndi zopyapyala kwambiri, nthawi zambiri zimayang'ana kumapeto kowala kwambiri. Malo oterewa amawonjezera zofooka pamwamba osati kuzimiririka, kotero muyenera kusamala.
Magazini ya Tube & Pipe Journal inakhala magazini yoyamba yodzipereka kutumikira makampani opanga mapaipi achitsulo mu 1990. Masiku ano, ikadali magazini yokhayo ku North America yodzipereka ku makampani opanga mapaipi ndipo yakhala gwero lodalirika kwambiri la chidziwitso kwa akatswiri opanga mapaipi.
Tsopano popeza tili ndi mwayi wopeza kope la digito la The FABRICATOR, titha kupeza mosavuta zinthu zofunika kwambiri m'makampani.
Magazini ya digito ya The Tube & Pipe Journal tsopano ikupezeka mosavuta, zomwe zimapangitsa kuti zinthu zofunika kwambiri m'makampani zipezeke mosavuta.
Sangalalani ndi mwayi wonse wopeza kope la digito la STAMPING Journal, lomwe limapereka kupita patsogolo kwaposachedwa kwaukadaulo, njira zabwino kwambiri komanso nkhani zamakampani pamsika woponda zitsulo.
