Me ka piʻi nui ʻana o ka makemake no nā huahana ʻoi aku ka maikaʻi a me ka palekana, ua lilo ka hemming sheet metal i mea maʻamau i ka hana maʻamau ma ka pā paʻi.A me ka nui o nā mea hoʻonā kaomi brake hemming ma ka mākeke, ʻo ka hoʻoholo ʻana i ka hopena kūpono no kāu mau hana hiki ke lilo i papahana nona iho.
E heluhelu ma lalo e aʻo hou e pili ana i nā ʻano mea hana hemming, a i ʻole e ʻimi i kā mākou Hemming Series a loaʻa i ka ʻōlelo aʻoaʻo loea no ka mea hana hemming maikaʻi loa no kāu mau pono!
E ʻimi iā Hemming Series
He aha ka hemming metala?
E like me ka ʻoihana ʻaʻahu a me ka humuhumu ʻana, ʻo ka hemming sheet metal e pili ana i ka pelu ʻana o kekahi papa o nā mea ma luna o kekahi i mea e hana ai i kahi ʻaoʻao palupalu a poʻe.Hoʻohana ʻia ia i loko o nā ʻoihana like ʻole e like me ka refrigeration, ka hana ʻana i ke keʻena, ka hana ʻana i nā lako keʻena, nā lako hana meaʻai, a me nā papa a me nā lako mālama i ka inoa wale nō.
Ma ka mōʻaukala, ua hoʻohana maʻamau ka hemming i nā mea mai 20 ga.ma o 16 ga.kila māmā.Eia nō naʻe, me ka hoʻomaikaʻi hou ʻana i ka ʻenehana hemming i loaʻa, ʻaʻole ia he mea maʻamau ka ʻike ʻana i ka hemming i hana ʻia ma 12 - 14 ga., A i nā hihia liʻiliʻi e like me ka mānoanoa e like me 8 ga.mea waiwai.
Hiki i nā huahana metala hemming ke hoʻomaikaʻi i ka nani, hoʻopau i ka ʻike ʻana i nā ʻaoʻao ʻoi aku a me nā burr ma nā wahi e pilikia ai ka ʻāpana ke lawelawe, a hoʻohui i ka ikaika i ka ʻāpana i hoʻopau ʻia.ʻO ke koho ʻana i nā mea hana hemming kūpono e pili ana i ka nui o kāu e hoʻopaʻa ʻia ai a me nā mānoanoa mea āu e manaʻo ai e hem.

ʻO nā mea hana hāmare ke ʻano kahiko loa o ka hemming.Ma kēia ʻano, hoʻopiʻi ʻia ka ʻaoʻao o ka mea me kahi pūʻulu o nā mea hana kihi acute i kahi kihi i hoʻopili ʻia ma kahi o 30 °.I ka wā o ka hana ʻelua, hoʻopalapala ʻia ka flange mua i hoʻopaʻa ʻia ma lalo o kahi pūʻulu o nā mea hana palahalaha, aia i kahi kuʻi a make me nā maka palahalaha e hana i ka hem.No ka mea e pono ai ke kaʻina hana ʻelua hoʻonohonoho mea hana, ʻoi aku ka maikaʻi o nā mea hana hāmare ma ke ʻano he koho pili kālā no nā hana hemming pinepine ʻole.

ʻO ka hoʻohana kūpono: ʻoi aku ka maikaʻi no ka hoʻopili ʻana i nā mea lahilahi.He kūpono no nā hem "ʻokiʻoki".
Kulou honua: ʻAe, akā kaupalena.
ʻO ka hui pū ʻana a me ka make (a i ʻole U-shaped hemming dies) e hoʻohana i ka 30° acute punch me ka ʻāwae palahalaha ma mua a me ka make ʻano U me kahi ākea ākea ma luna.E like me nā ʻano hemming a pau, ʻo ka piʻo mua e pili ana i ka hana ʻana i kahi 30ۡ° pre-bend.Loaʻa kēia ma ka hoʻokuʻi ʻana i ka mea i loko o ka puka U-like ma ka make.A laila kau ʻia ka mea ma luna o ka make me ka ʻaoʻao mua o ka piko e kū ana i luna.Hoʻokuʻu hou ʻia ka kuʻi i lalo i loko o ka puka U-like ma ka make a ʻo ka ʻāpae palahalaha o ka kuʻi e holomua ana ma ke kahua palahalaha.
Ma muli o ka ʻoiaʻiʻo o ka make ʻana o ka U-shaped hemming he paia paʻa o ke kila ma lalo o ka wahi i hana ʻia ai ka hana palahalaha, ʻo ka haʻahaʻa haʻahaʻa kiʻekiʻe i hāʻawi ʻia e kēia hoʻolālā e hana maikaʻi loa i ka hoʻokumu ʻana i nā hem "ʻohi ʻia".Ma muli o ka hoʻohana ʻana i kahi punch acute no ka pre-bend, hiki ke hoʻohana ʻia nā make hemming U-shaped no nā noi kulou honua.
ʻO ka hoʻololi ʻana i kēia hoʻolālā, ʻoiai aia ka ʻauwae palahalaha ma ke alo o ke kuʻi, pono e pāpaʻu ka hohonu i mea e pale ai i ka hoʻopili ʻana i ka mea i kona lele ʻana i luna e hana i ka 30-degere pre-piʻo.ʻO kēia hohonu pāpaʻu e ʻoi aku ka maʻalahi o ka paheʻe ʻana o ka mea i waho o ka ʻauwae palahalaha i ka wā o ka palahalaha, hiki ke hoʻopōʻino nui i nā manamana lima o ka pahu paʻi.ʻO ka maʻamau, he pilikia kēia inā ʻaʻole he kila galvanized ka mea, loaʻa kahi ʻaila ma ka ʻili, a i ʻole inā piʻo ka flange mua i hoʻopili ʻia i kahi kihi i ʻoi aku ka nui (ʻoi aku ka hāmama) ma mua o 30°.

I ka hoʻonui ʻia ʻana o ka mana paʻi paʻi a me ka lako polokalamu, ua kaulana loa ka make hemming ʻelua.I ka hoʻohana ʻana i kēia mau mea make, ua pio ka ʻāpana me ka 30° acute angle punch a me ka hemming die me ka 30° acute angle V-opening.ʻO nā ʻāpana o luna o kēia mau mea make i hoʻoili ʻia i ka pūnāwai a i ka wā o ka palahalaha, ua kau ʻia ka mea i hoʻopaʻa mua ʻia ma waena o kahi pūʻulu o nā ʻāwae palahalaha ma ke alo o ka make a ʻo ka ʻāwae palahalaha o luna e hoʻokuʻu ʻia i lalo e ke kuʻi i ka wā o ka hahau ʻana o ka. hipa kāne.E like me kēia, hoʻopalahalaha mua ʻia ka flange mua a hiki i ka hoʻopili ʻana o ka ʻaoʻao alakaʻi me ka lau palahalaha.
ʻOiai ka wikiwiki a me ka huahua nui, ʻelua mau pae hemming make i kā lākou drawbacks.Ma muli o ko lākou hoʻohana ʻana i ka punawai i luna, pono lākou e lawa i ke kaomi puna e paʻa ai ka pepa me ka ʻole e hāʻule iki a hiki i ka hoʻomaka ʻana o ka piko mua.Inā ʻaʻole lākou e hana pēlā, hiki ke paheʻe ka mea ma lalo o nā manamana lima hope a hoʻopōʻino iā lākou i ka hana ʻana o ka piko mua.Eia kekahi, koi lākou i ka wehe ʻana V e like me ʻeono manawa o ka mānoanoa o nā mea (ʻo ia hoʻi, no nā mea me ka mānoanoa o 2mm, make nā hemming i hoʻouka ʻia i ka puna e pono ai he 12mm v-wehe).

Noi Pono: Kūpono no nā hana hemming pinepine.
Kulou Universal: ʻAe.ʻO ka koho maʻalahi loa no ka hemming a me ke kuʻi honua.
ʻO ka ʻoiaʻiʻo, ʻo ka holomua hou a ʻoi loa ka holomua o ka mea hana hemming ʻo ka "Dutch bending table," i kapa ʻia hoʻi he "papakaukau hemming."E like me ka make ʻana o ka hemming i hoʻopiha ʻia i ka pūnāwai, ʻike ʻia nā papa kulou Dutch i kahi pūʻulu o nā ʻāwae palahalaha ma ke alo.Eia naʻe, ʻaʻole e like me ka make ʻana o ka hemming i hoʻopiha ʻia i ka pūnāwai, ua hoʻomalu ʻia nā ʻauwae palahalaha ma ka papa ʻaina Dutch ma o nā cylinders hydraulic.Hiki i ka hydraulic cylinders ke hoʻopaʻa i nā ʻano mānoanoa a me nā paona like ʻole no ka mea ua hoʻopau ʻia ka pilikia o ke kaomi puna.
Ke kānalua nei ma ke ʻano he mea paʻa paʻa, hōʻike pū ʻia nā papa kulou Dutch i ka hiki ke hoʻololi i nā make 30-degere, a kōkua pū i ko lākou hiki ke hoʻopaʻa i nā ʻano mānoanoa.Hoʻolilo kēia iā lākou i mea maʻalahi loa a hopena i kahi hōʻemi nui o ka manawa hoʻonohonoho.Loaʻa ka hiki ke hoʻololi i ka v-wehe, i hui pū ʻia me ka hiki ke hoʻohana i nā cylinders hydraulic e pani i nā ʻāwae palahalaha e hiki ai ke hoʻohana i ka ʻōnaehana ma ke ʻano he paʻa make ke hoʻohana ʻole ʻia no nā noi hemming.

Inā ʻoe e ʻimi nei e hoʻopaʻa i nā mea ʻoi aku ka mānoanoa ma mua o 12 ga., pono ʻoe i kahi hāmeʻa hoʻoneʻe palahalaha.Hoʻololi ʻia kahi mea paahana lalo hoʻoneʻe i ka mea hana kuʻuna lalo i hoʻohana ʻia i loko o kahi hoʻonohonoho hāmeʻa hāmare me kahi make i loaʻa nā ʻāpana ʻōwili, e hiki ai i ka mea paahana ke komo i ka ukana ʻaoʻao i hana ʻia i kahi hoʻonohonoho hāmeʻa hāmare.Ma ka lawe ʻana i ka ukana ʻaoʻao, hiki i ka mea hana hoʻoneʻe palahalaha lalo ke hiki i nā mea like me ka mānoanoa e like me 8 ga.e hoʻopaʻa ʻia ma kahi paʻi paʻi.Inā ʻoe e ʻimi nei i nā mea hem ʻoi aku ka mānoanoa ma mua o 12 ga., ʻo kēia wale nō ke koho i ʻōlelo ʻia.
ʻO ka hope loa, ʻaʻohe mea hana hemming i kūpono no nā noi hemming āpau.ʻO ke koho ʻana i ka mea paʻi paʻi brake hemming pono e pili ana i nā mea āu e manaʻo ai e kulou a me ka nui o kāu e hoʻopaʻa ʻia ai.E noʻonoʻo i ka laulā anana āu e manaʻo ai e kulou, a me ka nui o nā hoʻonohonoho e koi ʻia e hoʻopau i nā hana pono āpau.Inā ʻaʻole maopopo ʻoe i ka hopena hemming ʻoi aku ka maikaʻi no kāu mau hana, e kelepona i kāu mea kūʻai mea hana a i ʻole WILA USA no ke kūkākūkā manuahi.
