A production process of aluminum alloy window profiles

Abstract

The invention discloses a production process for an aluminum alloy window sectional material. The production process for the aluminum alloy window sectional material comprises the following steps: A1,cast ingot preparation; A2, soaking; A3, raw material preheating; A4, extrusion forming: an aluminum alloy cast ingot is extruded through an extruder, the aluminum alloy cast ingot is extruded by theextruder, so that the aluminum alloy cast ingot in an extrusion barrel is enabled to extrude towards an extrusion die and extruded out from a die hole of the extrusion die, and in the process, the temperature of the extrusion die is controlled to be 380 DEG C; A5, preliminary cooling: water cooling is adopted, and the extruded aluminum alloy section material is cooled to be 250-300 DEG C; A6, rolling straightening: the surface of the aluminum alloy section material is rolled through a straightening machine, so that the surface of the aluminum alloy section material is straight; A7, aftercooling: air cooling is adopted, and the aluminum alloy section material is cooled to be 200 DEG C and below; A8, heat treatment; and A9, surface treatment. The production process for the aluminum alloy window sectional material has the following advantage and effect: due to the production process, the accuracy of the straightness and the surface planeness of the aluminum alloy section material is increased, so that a guarantee on the installation dimensions of an aluminum alloy window prepared from the aluminum alloy sectional material is benefited.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a production process of an aluminum alloy window profile. Background technique [0002] Aluminum alloy windows are windows with frames and fan structures made of aluminum alloy profiles, which are divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows. Aluminum alloy windows are beautiful, airtight, and high-strength, and are widely used in the field of construction engineering. In home decoration, aluminum alloy doors and windows are often used to encapsulate balconies. The aluminum alloy profile is the main material of the aluminum alloy window, and the aluminum alloy profile is mainly used as the frame of the aluminum alloy window, so the straightness and flatness of the aluminum alloy profile are of great significance to the installation size of the aluminum alloy window. The existing production process of aluminum al...

Problems solved by technology

[0004] The above technical scheme has good adhesion, simple structure, and is convenient for adjusting the size of the die hole in the mould, but has the following defects: in this production process, the extruded aluminum alloy profile still has a high temperature, and the aluminum alloy profile is directly pulled after being extruded out of the extrusion die. The high-temperature aluminum alloy profile is relatively soft at this time. The straightness and flatness of alloy profiles are not up to standard
