ndodo ya extrusion kapena ram extrusion mu makina osindikizira a aluminium extrusion

Nkhosa yamphongo yotchedwa extrusion shaft, yomwe imatchedwanso kuti extrusion shaft, ndi imodzi mwa zipangizo zofunika kwambiri zowonjezera zomwe zimatumiza kupanikizika komwe kumapangidwa mu cylinder yayikulu ya extruder kupita ku billet mu silinda ya extrusion, zomwe zimapangitsa kuti bilu ikhale yopunduka ndi kutuluka kunja kwa extrusion. kufa dzenje kupanga extrusion mankhwala.Pulasitiki mapindikidwe kumachitika mu yamphamvu kuthamanga, choncho ali pansi kwambiri pa extrusion.Potulutsa chitoliro, ngati mapangidwe, kusankha ndi kugwiritsa ntchito nkhosa yamphongo ndizosayenera, zimakhala zosavuta kupindika ndi kupunduka, zomwe zimakhala chimodzi mwazifukwa zazikulu za eccentricity ya chitoliro.Kuphatikiza apo, nkhosa yamphongo yotulutsa imatha kutulutsanso kuphwanya, kusweka komanso kugawanika kwa slag panthawi yogwira ntchito.

Nkhosa ya extrusion imagawidwa m'mitundu iwiri: yopanda kanthu komanso yolimba.Nkhosa zamphongo zopanda dzenje zimagwiritsidwa ntchito pamakina a chubu ndi ndodo.
Nkhosa ya extrusion nthawi zambiri imakhala yozungulira, yomwe imatha kugawidwa m'malekezero, mitsinje ndi mizu.

Pazikuluzikulu zotulutsa matani, nkhosa zamphongo zotulutsa zimapangidwa ndi gawo losinthika kuti ziwonjezere mphamvu yopindika nthawi yayitali.Panthawiyi, silinda ya extrusion iyenera kukhala ndi dzenje lamkati lokhala ndi gawo losiyana.

The awiri akunja a extrusion nkhosa anatsimikiza molingana ndi m'mimba mwake wamkati extrusion yamphamvu.
Kunja kwa nkhosa yamphongo yopingasa ya extruder yopingasa nthawi zambiri kumakhala kokulirapo kuposa nkhosa yamphongo yotulutsa.M'mimba mwake mkati mwa silinda ndi 4-10mm yaying'ono.

Kutalika kwa nkhosa yamphongo ndi yofanana ndi kutalika kwa nkhokwe ya extrusion komanso kutalika kwa silinda ya extrusion kuphatikiza 5 mpaka 10mm, pofuna kukankhira kupanikizika mopitirira muyeso (onani zotsalira za extrusion) ndi gasket extrusion kunja kwa silinda ya extrusion.Zakuthupi za nkhosa yamphongo ndi chrome-nickel-molybdenum ndi chrome-nickel-tungsten alloy.Thupi la ndodo lophatikizidwa limapangidwa ndi chromium-nickel-tungsten-vanadium alloy, ndipo muzu wake umapangidwa ndi chromium-nickel-molybdenum alloy.

Nkhosa ya extrusion imakumana ndi kupsinjika kwakukulu kopindika nthawi yayitali komanso kupsinjika kwakanthawi pakugwira ntchito.Choncho, bata ndi
mphamvu ya extrusion nkhosa ayenera kufufuzidwa pa extrusion.
