Ụkpụrụ na-arụ ọrụ nke Isi Extrusion Isi nke Aluminom Extrusion Machine

Extrusion isi maka aluminom extrusion

Isi extrusion bụ ngwá ọrụ extrusion kachasị dị egwu nke a na-eji eme ihe n'ime usoro nkwụsị nke aluminum (Fig 1). Ogo nke ngwaahịa a na-agbanye na mmepụta nke extruder na-adabere na ya.

Ọrụ nke isi extrusion

Ọrụ nke isi extrusion dị ka ọ dị mfe na nlele mbụ. Akụkụ a dị ka ihe na-aga n'ihu nke mkpanaka extrusion ma emebere ya iji mee ka aluminom alloy dị ọkụ ma dị nro ozugbo site na anwụ. Achịcha extrusion ga-arụ ọrụ ndị a:

Isi extrusion bụ akụkụ nke ngwá ọrụ extrusion nke a na-enwe nrụgide dị elu. The extrusion isi bụ ngwá ọrụ die ígwè (eg H13 ígwè). Tupu ịmalite pịa, a na-ekpo ọkụ isi extrusion na okpomọkụ nke ọ dịkarịa ala 300 ºC. Nke a na-eme ka nchara na-eguzogide nrụgide okpomọkụ ma na-egbochi mgbawa n'ihi ujo ọkụ.

Okpomọkụ nke billet, akpa na anwụ

Billet ekpo oke ọkụ (n'elu 500ºC) ga-ebelata nrụgide nke isi extrusion n'oge usoro mkpochapụ. Nke a nwere ike iduga na mgbasawanye nke isi extrusion ezughị ezu, nke na-eme ka metal billet tinye n'ime oghere dị n'etiti isi extrusion na akpa. Nke a nwere ike belata ọrụ ndụ nke dummy ngọngọ na ọbụna iduga ịrịba plastic deformation nke metal ya site extrusion isi. Ọnọdụ ndị yiri ya nwere ike ime na arịa nwere mpaghara kpo oku dị iche iche.

Ịrapara isi extrusion na billet bụ nnukwu nsogbu. Ọnọdụ a na-ahụkarị na ibe ọrụ ogologo na alloys dị nro. Ihe ngwọta nke oge a maka nsogbu a bụ itinye mmanụ mmanu na-adabere na boron nitride na njedebe nke workpiece.

A ghaghị ịlele isi extrusion kwa ụbọchị.

A na-ekpebi njigide aluminom enwere ike site na nlele anya.

Lelee mmegharị n'efu nke mkpanaka na mgbanaka, yana ntụkwasị obi nke ndozi nke kposara niile.
