1 ʻO ka noi ʻana o ka alumini alumini i ka ʻoihana kaʻa
I kēia manawa, ʻoi aku ma mua o 12% a 15% o ka hoʻohana ʻana i ka alumini honua e hoʻohana ʻia e ka ʻoihana kaʻa, me kekahi mau ʻāina hoʻomohala ma mua o 25%. I ka makahiki 2002, ua hoʻopau ka ʻoihana kaʻa holoʻokoʻa ʻEulopa ma mua o 1.5 miliona metric tons o ka alumini alumini i hoʻokahi makahiki. Ma kahi o 250,000 metric tons i hoʻohana ʻia no ka hana kino, 800,000 metric tons no ka hana ʻana o ka ʻōnaehana hoʻoili kaʻa, a me kahi 428,000 metric tons no ka hana ʻana i nā kaʻa a me nā ʻōnaehana hoʻomaha. Ua ʻike ʻia ua lilo ka ʻoihana hana kaʻa i mea kūʻai nui loa i nā mea alumini.
2 Nā Manaʻo ʻenehana no nā Pepa Stamping Aluminum ma Stamping
2.1 Hoʻokumu a make i nā koi no nā Pepa Aluminum
ʻO ke kaʻina hana no ka alumini alumini like ʻole me nā lau i ʻōwili ʻia maʻamau, me ka hiki ke hōʻemi i nā mea ʻōpala a me nā hana ʻōpala alumini ma o ka hoʻohui ʻana i nā kaʻina hana. Eia nō naʻe, aia nā ʻokoʻa i nā koi die i hoʻohālikelike ʻia me nā lau i ʻōwili ʻia.
2.2 Ka Waihona Loihi o na Pepa Aluminum
Ma hope o ka paʻakikī o ka ʻelemakule, hoʻonui ka ikaika hua o nā ʻāpana alumini, e hōʻemi ana i kā lākou hiki ke hana i nā kihi. I ka hana ʻana i nā mea make, e noʻonoʻo e hoʻohana i nā mea i kūpono i nā koi kikoʻī kiʻekiʻe a hana i ka hōʻoia kūpono ma mua o ka hana ʻana.
ʻO ka ʻaila ʻaila/ʻaila pale pale i hoʻohana ʻia no ka hana ʻana i ka volatilization. Ma hope o ka wehe ʻana i ka pahu pepa, pono e hoʻohana koke ʻia a hoʻomaʻemaʻe ʻia a hoʻomaʻemaʻe ʻia ma mua o ke kahakaha ʻana.
ʻAʻole pono e mālama ʻia ka ʻili ma kahi ākea. Pono ka hoʻokele kūikawā (packaging).
3 Nā Manaʻo ʻenehana no nā Pepa Stamping Aluminum i ka welding
ʻO nā kaʻina hana hoʻoheheʻe nui i ka wā o ka hui ʻana o nā kino alumini e komo pū me ke kuʻi kūʻē, CMT hoʻololi hoʻololi anuanu, tungsten inert gas (TIG) welding, riveting, punching, a me ka wili / polishing.
3.1 wiliwili me ka Riveting ole no na Pepa Aluminum
Hoʻokumu ʻia nā ʻāpana pepa alumini me ka ʻole riveting e ka extrusion anu o ʻelua a ʻoi aʻe paha o nā ʻāpana metala me ka hoʻohana ʻana i nā mea paʻi a me nā mold kūikawā. Hoʻokumu kēia kaʻina hana i nā wahi pili i hoʻopili ʻia me kahi ikaika tensile a me ka shear. Hiki ke like a ʻokoʻa paha ka mānoanoa o nā pepa hoʻohui, a hiki iā lākou ke loaʻa i nā papa adhesive a i ʻole nā papa waena, me nā mea like a ʻokoʻa paha. Hoʻopuka kēia ʻano i nā pilina maikaʻi me ka ʻole o nā mea hoʻohui kōkua.
3.2 Kūʻē kūʻē
I kēia manawa, hoʻohana maʻamau ka hoʻoheheʻe ʻana o ka alumini alumini i nā kaʻina hana kuʻi ʻana i ka medium-frequency a i ʻole kiʻekiʻe. Hoʻoheheʻe kēia kaʻina hana hoʻoheheʻe i ka metala kumu i loko o ke anawaena o ka electrode welding i kahi manawa pōkole loa e hana i kahi wai weld,
ʻoluʻolu wikiwiki nā wahi wili e hana i nā pilina, me ka liʻiliʻi o ka hiki ke hana i ka lepo alumini-magnesium. ʻO ka hapa nui o nā uahi hoʻoheheʻe i hana ʻia me nā ʻāpana oxide mai ka ʻili metala a me nā haumia ʻili. Hāʻawi ʻia ka ea hoʻokuʻu kūloko i ka wā o ke kaʻina hana e hoʻoneʻe koke i kēia mau ʻāpana i ka lewa, a he liʻiliʻi ka waiho ʻana o ka lepo alumini-magnesium.
3.3 CMT Welding Transition Cold a me TIG Welding
ʻO kēia mau kaʻina hana hoʻoheheʻe ʻelua, ma muli o ka pale ʻana i ke kinoea inert, e hana i nā ʻāpana metala alumini-magnesium liʻiliʻi i nā wela kiʻekiʻe. Hiki i kēia mau ʻāpana ke pāpaʻi i loko o ke kaiapuni hana ma lalo o ka hana a ka arc, e hōʻike ana i kahi pilikia o ka pahū lepo aluminika-magnesium. No laila, pono ka mālama ʻana a me ka mālama ʻana i ka pahū lepo.
4 Nā Pono ʻenehana no nā Pepa Stamping Aluminum ma Edge Rolling
He mea koʻikoʻi ka ʻokoʻa ma waena o ka ʻōwili lihi alumini alumini a me ka ʻōwili pepa maʻamau. ʻOi aku ka liʻiliʻi o ka alumini ma mua o ke kila, no laila pono e pale ʻia ka piʻi nui i ka wā o ka ʻōwili ʻana, a ʻo ka wikiwiki o ka holo ʻana e lohi, maʻamau 200-250 mm/s. ʻAʻole pono kēlā me kēia kihi ʻōwili ma mua o 30 °, a pono e pale ʻia ka ʻōwili ʻana i ke ʻano V.
ʻO nā koi wela no ka ʻōwili alumini alumini: Pono e hana ʻia ma 20 ° C lumi wela. ʻAʻole pono e hoʻowili koke ʻia nā ʻāpana i lawe ʻia mai ka waiho anuanu.
5 Nā ʻano a me nā ʻano o ka Rolling Edge no nā Pepa Stamping Aluminum
5.1 Nā ʻano o ka ʻōwili lihi no nā Pepa Stamping Aluminum
ʻEkolu mau ʻanuʻu ka ʻōwili maʻamau: ʻo ka ʻōwili mua ʻana, ka ʻōwili lua mua, a me ka ʻōwili hope. Hoʻohana pinepine ʻia kēia inā ʻaʻohe koi ikaika a maʻamau nā kihi flange o waho.
ʻEhā ʻanuʻu ka ʻōwili kaila ʻEulopa: ka ʻōwili mua ʻana, ka ʻōwili mua ʻana ma mua, ka ʻōwili hope loa, a me ka ʻōwili ʻana i ke ʻano ʻEulopa. Hoʻohana maʻamau kēia no ka ʻōwili ʻana i ka ʻaoʻao lōʻihi, e like me nā uhi mua a me hope. Hiki ke hoʻohana ʻia ka ʻōwili ʻano ʻEulopa e hōʻemi a hoʻopau paha i nā hemahema o ka ʻili.
5.2 Nā ʻano o ka Rolling Edge no nā Pepa Stamping Aluminum
No nā lako alumini ʻāpana, pono e hoʻopololei ʻia a mālama mau ʻia me ka 800-1200# pepa ʻaʻole i loaʻa nā ʻōpala alumini ma ka ʻili.
6 Nā kumu like ʻole o nā pōʻino i hoʻokumu ʻia e ka ʻōwili ʻana i nā ʻaoʻao o nā Pepa Stamping Aluminum
Hōʻike ʻia nā kumu like ʻole o nā hemahema i ka ʻōwili ʻia ʻana o nā ʻāpana alumini ma ka papa.
7 Nā Koina ʻenehana no ka uhi ʻana i nā Pepa Stamping Aluminum
7.1 Nā Kuʻuna a me nā hopena o ka holo ʻana o ka holoi wai no nā Pepa Stamping Aluminum
ʻO ka passivation holoi wai e pili ana i ka wehe ʻana i ke kiʻiʻoniʻoni oxide maoli a me nā ʻaila ʻaila ma ka ʻili o nā ʻāpana alumini, a ma o ka hopena kemika ma waena o ka alumini alumini a me kahi hopena ʻakika, e hana ana i kahi kiʻiʻoniʻoni oxide ma luna o ka papa hana. ʻO ke kiʻiʻoniʻoni oxide, nā ʻaila ʻaila, ka wili, a me ka hoʻopaʻa paʻa ʻana ma ka ʻili o nā ʻāpana alumini ma hope o ke kaha ʻana i nā mea āpau. No ka hoʻomaikaʻi ʻana i ka hoʻopili ʻana o nā adhesives a me nā welds, hoʻohana ʻia kahi kaʻina hana kemika no ka mālama ʻana i nā pilina pili lōʻihi a me ke kūpaʻa kūʻē ʻana ma luna o ka ʻili, e loaʻa ai ka maikaʻi wili. No laila, ʻo nā ʻāpana e koi ana i ka hoʻoheheʻe ʻana i ka laser, ka welding hoʻololi metala anuanu (CMT), a me nā kaʻina hana wili ʻē aʻe e pono e hana i ka passivation holoi wai.
7.2 Ke Kaʻina Hana o ka Holowai Holoi Wai no nā Pepa Stamping Aluminum
ʻO nā mea hana passivation holoi wai he wahi degreasing, kahi holoi wai ʻoihana, kahi passivation, kahi holoi wai maʻemaʻe, kahi maloʻo, a me kahi ʻōnaehana hoʻopau. Hoʻokomo ʻia nā ʻāpana alumini e mālama ʻia i loko o kahi hīnaʻi holoi, paʻa, a hoʻohaʻahaʻa ʻia i loko o ka pahu. I loko o nā pahu i loaʻa nā solvents like ʻole, holoi pinepine ʻia nā ʻāpana me nā hopena hana āpau i loko o ka pahu. Hoʻolako ʻia nā pahu pahu a pau me nā circulation pumps a me nā nozzles e hōʻoia i ka holoi like ʻana o nā ʻāpana āpau. Penei ka holo ana o ke kaʻina hana passivation holoi wai: degreasing 1→degreasing 2→holoi wai 2→holoi wai 3→passivation→holoi wai 4→holoi wai 5→holoi wai 6→holo. Hiki i nā pahu alumini ke hoʻokuʻu i ka holoi wai 2.
7.3 Ke Kaʻina Hoʻomaloʻo no ka Holoi ʻana o ka Holoi ʻana i ka wai o nā Pepa Stamping Aluminum
Ma kahi o 7 mau minuke e piʻi aʻe ka wela o ka ʻāpana mai ka lumi wela a hiki i 140 ° C, a ʻo ka manawa hoʻōla liʻiliʻi no nā mea hoʻopili he 20 mau minuke.
Hoʻokiʻekiʻe ʻia nā ʻāpana alumini mai ka lumi wela a hiki i ka mahana paʻa ma kahi o 10 mau minuke, a ʻo ka manawa paʻa no ka alumini ma kahi o 20 mau minuke. Ma hope o ka hoʻopaʻa ʻana, hoʻomaha ʻia mai ka mahana paʻa ponoʻī a 100 ° C no kahi o 7 mau minuke. Ma hope o ka hoʻopaʻa ʻana, hoʻoluʻu ʻia i ka lumi wela. No laila, ʻo ke kaʻina hoʻomaloʻo holoʻokoʻa no nā ʻāpana alumini he 37 mau minuke.
8 Ka hopena
Ke neʻe nei nā kaʻa o kēia wā i ka māmā, ka wikiwiki, ka palekana, ka ʻoluʻolu, ke kumu kūʻai haʻahaʻa, ka haʻahaʻa haʻahaʻa, a me ka ikaika o ka ikehu. ʻO ka hoʻomohala ʻana o ka ʻoihana kaʻa e pili pono ana i ka pono o ka ikehu, ka mālama ʻana i ke kaiapuni, a me ka palekana. Me ka hoʻonui ʻana i ka ʻike o ka mālama ʻana i ke kaiapuni, loaʻa i nā mea alumini nā mea maikaʻi ʻole i ke kumukūʻai, ka ʻenehana hana, ka hana mechanical, a me ka hoʻomohala hoʻomau i hoʻohālikelike ʻia me nā mea māmā. No laila, e lilo ka alumini alumini i mea māmā i makemake ʻia i ka ʻoihana kaʻa.
