Processing and forming method of bridge-cut-off aluminum alloy section bar

Abstract

The invention relates to a processing and forming method of a bridge-cut-off aluminum alloy section bar. The method mainly comprises the following steps of prefabricating the section bar, and performing die-casting forming, fine processing and other processes, wherein adopted aluminum alloy die-casting forming equipment comprises a bottom plate, a forming device, a pressing device and a collectingdevice. The method can solve the following problems when an existing bridge-cut-off aluminum alloy section bar is die-cast and formed: a, when the existing aluminum alloy section bar is die-cast andformed, scratching and deforming are often caused, and even a plate is cracked; and b, an existing aluminum alloy section bar die-casting machine has low die-casting speed, low automation degree and inflexibility, cannot guarantee the quality of the aluminum alloy section bar, cannot guarantee the stability of a die-casting material during die-casting, cannot guarantee the cleanness in the die-casting machine after die-casting, influences the next use, reduces the die-casting forming efficiency and influences the appearance quality of the aluminum alloy section bar. The die-casting forming efficiency and quality of the bridge-cut-off aluminum alloy section bar can be improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy profiles, in particular to a processing and forming method for broken bridge aluminum alloy profiles. Background technique [0002] The principle of the broken bridge aluminum alloy profile is to use nylon to separate and tightly connect the two layers of aluminum alloys indoors and outdoors into a whole, forming a new heat-insulating aluminum profile. Doors and windows made of broken bridge aluminum alloy profiles It has good wind resistance, rain resistance and impermeability, strong heat preservation, sound insulation and noise reduction performance, strong corrosion resistance, small deformation and good fire performance. The broken bridge aluminum alloy profile needs to be die-casted during production. [0003] However, the following problems exist in the die-casting of the existing bridge-broken aluminum alloy profiles: a. When the existing aluminum alloy profiles are die-casted, scra...

Problems solved by technology

[0003] However, the following problems exist in the die-casting of the existing bridge-broken aluminum alloy profiles: a. When the existing aluminum alloy profiles are die-casted, scratches, deformations, and even cracks of the sheet often occur, which makes the molding invalid. The qualified rate of products is low, resulting in waste of raw materials and waste of production time; b, the existing aluminum alloy profile die-casting machines have slow die-casting speed, low degree of automation, and are not flexible enough to guarantee the quality of aluminum alloy profiles, and cannot guarantee the quality of aluminum alloy profiles during die-casting The stability of die-casting materials, after die-casting, the cleanliness of the die-casting machine cannot be guaranteed, which will affect the next use, reduce the efficiency of die-casting molding, and affect the appearance quality of aluminum alloy profiles, which can improve the efficiency of die-casting molding of broken bridge aluminum alloy profiles. efficiency and quality
