Ua kapa ʻia nā kaʻa "nā mīkini i hoʻololi i ka honua."Ma muli o ka pilina ʻoihana ikaika o ka ʻoihana kaʻa, manaʻo ʻia ʻo ia he hōʻailona koʻikoʻi o ka pae hoʻokele waiwai o ka ʻāina.ʻEhā kaʻina hana nui i loko o nā kaʻa, a ʻo ke kaʻina hoʻopaʻa ʻana ka mea nui o nā kaʻina hana nui ʻehā.A ʻo ia hoʻi ka mua o nā kaʻina hana nui ʻehā.
Ma kēia ʻatikala, e hōʻike mākou i ke kaʻina hana stamping i ka hana kaʻa.

1. He aha ka Stamping?
1) ʻO ka wehewehe ʻana o ka hoʻopaʻa ʻana
ʻO Stamping kahi ʻano hana hana e hoʻopili ai i ka ikaika o waho i nā papa, nā ʻāpana, nā paipu, a me nā ʻaoʻao e nā kaomi a me nā ʻōpala e hana ai i ka deformation plastic a i ʻole ka hoʻokaʻawale ʻana no ka loaʻa ʻana o nā mea hana (nā ʻāpana stamping) o ke ʻano a me ka nui.ʻO ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana no ka hana plastik (a i ʻole ka hana kaomi).ʻO nā blanks no ka hoʻopaʻa ʻana, ʻo ia ka nui o nā ʻāpana kila wela a ʻōwili ʻia i ke anu.Ma waena o nā huahana kila ma ka honua, 60-70% nā papa, ka hapa nui o ia mau mea i hoʻopaʻa ʻia i nā huahana i hoʻopau ʻia.
ʻO ke kino, ka pahu pahu, ka pahu wahie, ka ʻūhā radiator o ke kaʻa, ka pahu mahu o ka paila, ka pūpū o ka ipu, ka pahu hao silika kila o ka moto a me nā mea uila, a pēlā aku.Nui nō hoʻi nā ʻāpana stamping i nā huahana e like me nā mea kani a me nā mika, nā mea pono hale, nā paikikala, nā mīkini keʻena, a me nā mea ola.
2) Nā hiʻohiʻona kaʻina hana stamping
- ʻO Stamping kahi hana hana me ka hana kiʻekiʻe a me ka hoʻohana haʻahaʻa haʻahaʻa.
- He kūpono ke kaʻina hana stamping no ka hana ʻana i nā ʻāpana nui o nā ʻāpana a me nā huahana, kahi maʻalahi e ʻike i ka mechanization a me ka automation, a he kiʻekiʻe ka hana hana.I ka manawa like, ʻaʻole hiki i ka hana stamping ke hoʻoikaika wale i ka hoʻemi ʻana i ka ʻōpala a ʻaʻohe hana ʻōpala akā inā he koena i kekahi mau hihia, hiki ke hoʻohana piha ʻia.
- He kūpono ke kaʻina hana.ʻAʻohe kiʻekiʻe o ke akamai e koi ʻia e ka mea hoʻohana.
- ʻAʻole pono e mīkini ʻia nā ʻāpana i hoʻopaʻa ʻia a loaʻa ka pololei kiʻekiʻe.
- Loaʻa ka hoʻololi maikaʻi ʻana i nā ʻāpana stamping.He kūpaʻa maikaʻi ke kaʻina hana stamping, a hiki ke hoʻohana ʻia nā ʻāpana stamping like me ka ʻole e pili ana i ka hui a me ka hana huahana.
- No ka mea, ua hana ʻia nā ʻāpana stamping me ka metala, ʻoi aku ka maikaʻi o ko lākou ʻili, e hāʻawi ana i nā kūlana kūpono no nā kaʻina hana maʻamau ma hope (e like me ka electroplating a me ka pena).
- Hiki ke loaʻa nā ʻāpana me ka ikaika kiʻekiʻe, rigidity kiʻekiʻe, a me ka māmā.
- He haʻahaʻa ke kumu kūʻai o nā ʻāpana heʻi i hana nui ʻia me nā mold.
- Hiki ke hana i nā ʻāpana me nā ʻano paʻakikī i paʻakikī ke hana ʻia e nā ʻano hana metala ʻē aʻe.
3) Kaʻina hana heʻi
(1) Kaʻina hoʻokaʻawale:
Hoʻokaʻawale ʻia ka lau ma kahi laina contour ma lalo o ka hana o ka ikaika o waho e loaʻa ai nā huahana i hoʻopau ʻia a semi-hoʻopau ʻia me kahi ʻano, ka nui, a me ka maikaʻi ʻoki ʻia.
Kūlana hoʻokaʻawale: ʻOi aku ke koʻikoʻi i loko o ka mea deformed i ka palena ikaika σb.
a.Blanking: E hoʻohana i ka make no ka ʻoki ʻana ma ka ʻaoʻao i pani ʻia, a ʻo ka ʻāpana i kuʻi ʻia he ʻāpana.Hoʻohana ʻia e hana i nā ʻāpana pālahalaha o nā ʻano like ʻole.
b.Kuʻi: E hoʻohana i ka make e kuʻi ma ka ʻaoʻao i pani ʻia, a ʻo ka ʻāpana i kuʻi ʻia he ʻōpala.Aia kekahi mau ʻano e like me ke kuʻi maikaʻi, ke kuʻi ʻaoʻao, a me ke kuʻi kau ʻana.
c.ʻokiʻoki: ʻokiʻoki a ʻokiʻoki i nā kihi o nā ʻāpana i hana ʻia i kekahi ʻano.
d.Hoʻokaʻawale: E hoʻohana i ka make no ke kuʻi ʻana ma kahi ʻaoʻao i pani ʻole ʻia e hana i ka hoʻokaʻawale.Ke hui pū ʻia nā ʻāpana hema a me ka ʻākau, hoʻohana hou ʻia ke kaʻina kaʻawale.
(2) Kaʻina hana:
Hoʻopili ʻia ka blank me ka ʻole o ka haki ʻana no ka loaʻa ʻana o nā huahana i hoʻopau ʻia a semi-hoʻopau ʻia o kekahi ʻano a me ka nui.
Nā kūlana hana: ikaika hua σS
a.Ke kaha kiʻi: Ka hana ʻana i ka pepa pākaʻi i mau ʻāpana ʻāpana hāmama.
b.Flange: Hoʻokumu ʻia ka ʻaoʻao o ka lau a i ʻole ka huahana semi-finished i kahi ʻaoʻao kūpaʻa ma kahi pihi e like me kekahi curvature.
c.Hoʻohu: He ʻano hana i hoʻohana ʻia no ka hoʻomaikaʻi ʻana i ka pololei o nā ʻāpana i hana ʻia a i ʻole ka loaʻa ʻana o kahi radius fillet liʻiliʻi.
d.Hoʻololi: Hana ʻia kahi ʻaoʻao kū ma luna o kahi pepa i kuʻi mua ʻia a i ʻole huahana semi-finished a i ʻole ma kahi ʻāpana ʻole.
e.Piʻo: ʻO ke kulou ʻana i ka lau i nā ʻano like ʻole ma kahi laina pololei hiki ke hana i nā ʻāpana me nā ʻano paʻakikī loa.
2. Hehi make
1) Hoʻokaʻawale make
E like me ke kumu hana, hiki ke hoʻokaʻawale ʻia i: kiʻi make, trimming punching die, a me flanging shaping die.
2) ʻO ke ʻano kumu o ka ʻōpala
Hoʻokumu pinepine ʻia ka make kuʻi i nā make o luna a me lalo (convex a concave die).
3) Huina:
Mahele hana
Ke alakaʻi
Hoʻonohonoho
Ke kaupalena ana
ʻĀpana lohi
Hapai a huli
3. Lako Hoopapa
1) Mīkini Paʻi
E like me ke ʻano o ka moena, hiki ke hoʻokaʻawale ʻia nā paʻi i ʻelua mau ʻano: nā paʻi wehe a me nā kaomi paʻa.
Wehe ka paʻi hāmama ma nā ʻaoʻao ʻekolu, ʻo ka moenaʻAno-C, a ilihune ka oolea.Hoʻohana maʻamau ia no nā kaomi liʻiliʻi.Ua wehe ʻia ka paʻi paʻa ma mua a ma hope, ua pani ʻia ka moena, a ua maikaʻi ka paʻa.Hoʻohana maʻamau ia no nā paʻi nui a me waena.
E like me ke ʻano o ka hoʻokele slider force, hiki ke hoʻokaʻawale ʻia ka paʻi i loko o ka mīkini mīkini akaomi hydraulic.
2) Uncoiling laina
Mīkini ʻāhi
Hoʻohana nui ʻia ka mīkini ʻāwī e ʻoki i nā kihi pololei o nā ʻano nui o nā ʻāpana metala.ʻO nā palapala hoʻoili he mechanical a hydraulic.
4. Stamping Material
He mea koʻikoʻi ka stamping mea e pili ana i ka maikaʻi o ka ʻāpana a me ke ola make.I kēia manawa, ʻo nā mea i hiki ke hoʻopaʻa ʻia ʻaʻole wale ke kila haʻahaʻa haʻahaʻa akā ke kila kila, alumini a me ke alumini alumini, keleawe a me ke keleawe keleawe, etc.
ʻO ka pā kila i kēia manawa ka mea i hoʻohana nui ʻia i ka hoʻopaʻa ʻana i nā kaʻa.I kēia manawa, me ka koi no nā kino kaʻa māmā, hoʻohana nui ʻia nā mea hou e like me nā pā kila ikaika a me nā papa kila sandwich i nā kino kaʻa.
Papa kila kila
E like me ka mānoanoa: ka pā mānoanoa (ma luna o 4mm), ka pā waena (3-4mm), ka pā lahilahi (ma lalo o 3mm).ʻO nā ʻāpana hoʻoheheʻe kino kaʻa he mau papa lahilahi.
Wahi a ka moku'āina o ka'ōwili: ke kila wela wela, ke kila pale anuanu.
ʻO ka ʻōwili wela ka mea e hoʻopalupalu ai i ka mea ma kahi mahana i ʻoi aku ka kiʻekiʻe ma mua o ka mahana recrystallization o ka huila.A laila e kaomi i ka mea i loko o ka pepa lahilahi a i ʻole ka ʻāpana keʻa o ka billet me kahi huila kaomi, i hoʻololi ʻia ka mea, akā ʻaʻole i hoʻololi ʻia nā ʻano kino o ka mea.He ʻilihune ka paʻakikī a me ka maʻalahi o ka ʻili o nā papa wela, a he haʻahaʻa ke kumukūʻai.ʻO ke kaʻina hana ʻōwili wela a ʻaʻole hiki ke ʻōwili i ke kila lahilahi.
ʻO ka ʻōwili anuanu ke kaʻina o ka ʻōwili hou ʻana i ka mea me kahi huila kaomi ma kahi mahana haʻahaʻa ma mua o ka recrystallization wela o ka alloy e ʻae i ka mea e hoʻihoʻi hou ma hope o ka ʻōwili wela, depitting, a me nā kaʻina oxidation.Ma hope o ke kaomi ʻana i ke anu-recrystallization-annealing-annealing (e hana hou ʻia 2 a 3 mau manawa), ke hoʻololi nei ka metala i loko o ka mea i kahi hoʻololi molecular level (recrystallization), a me nā waiwai kino o ka alloy i hana ʻia.No laila, maikaʻi ka maikaʻi o kona ʻili, kiʻekiʻe ka hopena, kiʻekiʻe ka nui o ka huahana, a hiki i ka hana a me ka hoʻonohonoho ʻana o ka huahana ke hoʻokō i kekahi mau koi kūikawā no ka hoʻohana.
ʻO nā papa kila i hoʻopili ʻia i ka nui o nā pā hao kalapona i ʻōwili ʻia, nā pā kila haʻahaʻa haʻahaʻa i hoʻoheheʻe ʻia, nā pā kila i hoʻopaʻa ʻia no ka hoʻopaʻa ʻana, kiʻekiʻe ka ikaika o nā pā kila, etc.
5. Anana
ʻO ka gauge kahi mea nānā kūikawā i hoʻohana ʻia e ana a loiloi i ka maikaʻi o nā ʻāpana.
I ka hana kaʻa, ʻaʻohe mea no nā ʻāpana stamping nui, nā ʻāpana o loko, nā sub-assemblies welding me nā geometry spatial paʻakikī, a i ʻole no nā ʻāpana stamping liʻiliʻi liʻiliʻi, nā ʻāpana o loko, a me nā mea ʻē aʻe, hoʻohana pinepine ʻia nā mea nānā kūikawā e like me ke ʻano ʻike nui, hoʻohana ʻia e. e mālama i ka maikaʻi o ka huahana ma waena o nā kaʻina hana.
Loaʻa i ka ʻike gauge nā pono o ka wikiwiki, pololei, intuition, ʻoluʻolu, a me nā mea ʻē aʻe, a kūpono loa ia no nā pono o ka hana nui.
Loaʻa pinepine nā Gages i ʻekolu mau ʻāpana:
① Ka iwi iwi a me ka ʻāpana kumu
② Māhele kino
③ ʻO nā ʻāpana hana (ʻo nā ʻāpana hana: ka pahu wikiwiki, ka pine hoʻonohonoho, ka pine ʻike, ka movable gap slider, ke ana ʻana, ka pā paʻi kiʻi, etc.).
ʻO ia wale nō ka ʻike e pili ana i ke kaʻina hana hoʻopaʻa ʻana i ka hana kaʻa.He loea ʻo Zhengximea hana i na kaomi hydraulic, hāʻawi ʻana i nā mea hana stamping ʻoihana, e like menā kaomi hydraulic kiʻi hohonu.Eia hou, hoʻolako mākounā kaomi hydraulic no nā ʻāpana o loko.Inā he mau hemahema kāu, e ʻoluʻolu e kelepona mai iā mākou.
