Forming method of aluminum extrusion

Abstract

The invention provides a forming method of an aluminum extrusion. The forming method comprises the steps of: heating, temperature control, extruding through a die and setting, and specifically comprises the following steps of: heating, namely heating a raw material into a molten overheating melt raw material; temperature control, namely controlling the temperature of the molten overheating melt raw material and lowering the temperature until reaching a semi-solid state; extruding through the die, namely applying different pressures and flow rates to the raw material at the semi-solid state according to the thickness of the cross section of an extruded finished product, and passing through a pattern die; setting, namely drawing the extruded product passing through the pattern die, and cooling and setting the extruded product. The forming method of the aluminum extrusion has the advantages that the dimension of the raw material is unlimited, the width-to-thickness ratio of the extruded finished product is unlimited, the length is unlimited and the purpose of saving the energy consumption and minimizing extrusion equipment can be realized.

Description

technical field [0001] The present invention relates to a forming method, in particular to an aluminum extrusion forming method. Background technique [0002] Aluminum is one of the most abundant metal elements in the earth's crust. It is light in texture and has good ductility. In addition, it is not easy to rust. It can also be mixed with copper, iron and other metals to create strong and durable alloys. In the application of modern industry and daily life, aluminum metal products can be seen at any time, such as clean room partition material, machine frame, aluminum ladder, bathroom equipment handrail, hospital airport notice board rack, glass frame in department store display cabinet, Computer aluminum radiators, building air-conditioning vents, camera tripods, doors, windows and seat frames, high-speed train carriages, aircraft fuselages, etc. Because aluminum alloy has the advantages of light material, strong hardness and high recovery rate, it has become the material...

AI Technical Summary

Problems solved by technology

[0009] However, in the existing aluminum extrusion forming process, since the aluminum extruded rod is heated to the plastic temperature, and different extruded product sizes need to use the corresponding diameter of the aluminum extruded rod raw material, therefore, the diameter of the aluminum extruded rod raw material The use will be limited by the different extruded products

In addition, limited by the existing process equipment and its forming methods, the aspect ratio of aluminum extrusion products will be limited

In addition, a secondary heating step (steps P01 and P03) must be used, therefore, the loss of energy is quite large

In addition, the extrusion equipment used needs to be wider with the width of the extruded product. Therefore, for the extruded product with a considerable width, a considerable tonnage of extrusion equipment must be used.
