Abstract

The invention discloses an extrusion forming method of an aluminum alloy door and window profile. The extrusion forming method comprises the following steps of preparing a cast ingot; cleaning an extrusion cylinder and a forming mold of an extruder; carrying out the step-by-step preheating and heat preservation treatment on the extrusion cylinder and the forming mold of the extruder; preheating anextrusion tool; utilizing the finite element analysis of a DEFORM-3D software to carry out simulated extrusion forming; correcting the forming mold; and extrusion forming, stretching and straightening. Before extrusion forming, the corresponding preheating, heat preservation and cleaning treatment is carried out on the extrusion cylinder, the forming mold and the extrusion tool of the extruder, so that the surface quality of the formed aluminum alloy door and window profile can be effectively improved. The forming mold is subjected to the related analysis through the finite element analysis of the DEFORM-3D software before the formal extrusion forming, so that the influence of the parameter problem of the forming mold on the forming quality can be effectively avoided, and the size accuracy of the extrusion forming can be improved.

Description

technical field [0001] The invention relates to the field of aluminum alloy doors and windows, in particular to an extrusion molding method of aluminum alloy doors and windows profiles. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors and windows, referred to as aluminum doors and windows. Composite doors and windows, aluminum alloy has the characteristics of low density, high specific strength and specific stiffness, excellent castability and good processing performance, and also has good damping and shock absorption performance, which is very suitable as a door and window material; [0003] During the forming process of the existing aluminum alloy door and window profiles, it is easy to cause defects in the surface quality of the formed profiles. After forming, some further surface treatment is required to improve the ...
