Aluminum Extrusions

Extrusionʻo ia ke kaʻina hana e hana ai i nā ʻāpana metala pololei lōʻihi.ʻO nā ʻāpana keʻa i hiki ke hana ʻia, ʻokoʻa mai ka poepoe paʻa, ʻāpana ʻehā, a i nā ʻano L, nā ʻano T.ʻO nā paipu a me nā ʻano like ʻole he nui.Hana ʻia ka extrusion ma ke kaomi ʻana i ka metala i loko o kahi lua paʻa ma o kahi mea paahana, i ʻike ʻia he make me ka hoʻohana ʻana i ka mīkini a hydraulic paha.

Hoʻopuka ka Extrusion i ka ikaika compressive a me ka shear i loko o ka waihona.ʻAʻohe tensile i hana ʻia, kahi e hiki ai i ka deformation kiʻekiʻe me ka ʻole o ka haehae ʻana i ka metala.ʻO ka lua kahi i loaʻa ai ka mea maka i hoʻopaʻa ʻia me kahi mea pale lole.Hiki i kēia ke pale i nā ukana radial kiʻekiʻe i hana ʻia i ka wā e pahu ʻia ai ka mea i ka make.

ʻO nā extrusions, hoʻemi pinepine i ka pono o ka mīkini lua, akā ʻaʻole like me ka pololei o ka nui a i ʻole ka pau ʻana o ka ʻili e like me nā ʻāpana mīkini.ʻO ka hoʻopauʻana o kaʻili no ke kila he 3um;(125 uin), a ʻo Aluminum a me Magnesium he 0.8 um (30 uin).Eia nō naʻe, hiki i kēia kaʻina hana ke hana i nā ʻano like ʻole o nā ʻāpana keʻa i paʻakikī e hana i ka uku-pono me ka hoʻohana ʻana i nā ʻano hana ʻē aʻe.ʻO ka mānoanoa liʻiliʻi o ke kila ma kahi o 3 mm (0.120 in), ʻoiai ʻo Aluminum a me Magnesium ma kahi o 1mm (0.040 in).ʻO nā pauku keʻa liʻiliʻi he 250 mm2 (0.4 in2) no ke kila a ʻoi aku ka liʻiliʻi ma mua o kēlā no ka Aluminum a me Magnesium.ʻO 0.4 mm (0.015 in) ke kihi liʻiliʻi a me ka radii fillet no ka Aluminum a me Magnesium, a no ke kila, ʻo 0.8mm (0.030 in) ka radius kihi liʻiliʻi a me 4 mm (0.120 in).

Hoʻokuʻu anuanu:ʻO ka extrusion anuanu ke kaʻina hana i hana ʻia ma ka lumi wela a i ʻole ka wela kiʻekiʻe iki.Hiki ke hoʻohana ʻia kēia kaʻina hana no ka hapa nui o nā mea-e pili ana i ka hoʻolālā ʻana i nā mea hana ikaika e hiki ai ke pale i nā koʻikoʻi i hana ʻia e ka extrusion.ʻO nā laʻana o nā metala hiki ke hoʻokuʻu ʻia ʻo ke kēpau, tin, aluminika alumini, keleawe, titanium, molybdenum, vanadium, kila.ʻO nā laʻana o nā ʻāpana i hoʻokuʻu ʻia i ke anu ʻo ia nā paipu hiki ke hoʻoheheʻe ʻia, nā kini aluminika, nā cylinders, nā pahu pahu.ʻO nā pōmaikaʻi o ka extrusion anu:

• * ʻAʻohe mea hoʻohenehene
• *ʻO nā waiwai mechanical maikaʻi ma muli o ka hana anuanu koʻikoʻi inā lōʻihi nā mahana i hana ʻia ma lalo o ka mahana re-crystallization
• *Hoʻopau maikaʻi i ka ʻili me ka hoʻohana ʻana i nā lubricants kūpono

Wela Extrusion:Hana ʻia ka extrusion wela ma nā wela kiʻekiʻe, ma kahi o 50 a 75 % o ka helu heheʻe o ka metala.Hiki ke hoʻopaʻa ʻia mai ka 35-700 MPa (5076 - 101,525 psi).Ma muli o ke kiʻekiʻe o ka mahana a me ke kaomi a me kona hopena maikaʻi ʻole i ke ola make a me nā mea ʻē aʻe, pono ka lubrication maikaʻi.Hana ʻia ka ʻaila a me ka graphite ma nā mahana haʻahaʻa, akā ma nā mahana kiʻekiʻe e hoʻohana ʻia ka pauda aniani.

ʻO nā ʻāpana maʻamau i hana ʻia e nā extrusions nā ʻāpana ʻokiʻoki i hoʻohana ʻia i nā kaʻa a me nā noi kūkulu, nā lālā puka makani, nā railings, nā ʻāpana hana mokulele.
