Kugwirizana pakati pa ma alloys ndi tolerances

Aluminium ndi aluminiyamu, sichoncho?Chabwino, inde.Koma pali mazana amitundu yosiyanasiyana ya aluminiyamu.Ndikofunika kuti muyambe ntchito yanu poganizira mosamala za kusankha kwa alloy.Izi ndi zomwe muyenera kudziwa.

Pali zotayidwa mosavuta extrudable, monga 6060 kapena 6063, ndi aloyi pang'ono zochepa extrudable, monga 6005 ndi 6082. Ndipo amathamangira kwa aloyi amphamvu kuti n'zovuta extrude ndi kuyandikira katundu makina zitsulo.

Ma alloys okhala ndi magulu apamwamba ndi amphamvu, koma amakhalanso okwera mtengo.Pachifukwachi, ndikofunikira kuti muyambe ntchito yanu poganizira mosamala za kusankha kwa alloy.

Zigawo za alloy zimakhudza kupanga

Pali njira yapadera yopangira mtundu uliwonse wa aloyi.Ngakhale kuti aloyi imodzi imafunikira kuziziritsa pang'ono pambuyo pa njira yotulutsira, ina imafunika zambiri, kupitirira ngakhale kumadzi osati kuziziritsa mpweya.Njira zoziziritsazi zimakhala ndi zotsatira zofunikira pa kulolerana komanso kuthekera kopatsa mbiri mawonekedwe ena - ndikupanga zoletsa, makamaka kwa ma alloys omwe ndi ovuta kutulutsa.

Ndiyeno pali zinthu za mankhwala zimene aloyi ili.Zinthu monga manganese, zinki, chitsulo, mkuwa ndi vanadium zimapezeka pamlingo waukulu kapena wocheperako m'magulu olemera kwambiri.Vanadium ndiyofunikira pa ma alloys omwe amayamwa ngozi omwe amapezeka mumakampani amagalimoto.Zinthu zolemetsazi zimakhudzanso kwambiri kuvala kwa ma dies, ndipo chifukwa chake, zimakhudza kukula kwa mbiri - makamaka kulolerana - ndi kupatuka kwakukulu komwe kufa kumakhalabe.

Kulekerera ndikofunika

N’chifukwa chiyani kulolera kuli kofunika kwambiri?Izi ndi zifukwa zazikulu:

• Kukwaniritsa zofunikira zogwirira ntchito
• Kusankha pazipita zololedwa kufa kuvala
• Kutha kupanga mawonekedwe ofunikira a extrusion, yomwe imakhudzidwa ndi zovuta za mbiriyo komanso ngati ili yotseguka kapena yotsekedwa.
• Kukhazikitsa zofunikira zamaukadaulo atolankhani, monga kuziziritsa, mbali yotuluka ndi kutentha koyambira
