Analysis of forging process flow and process characteristics

Main introduction: aluminum alloy forging process and process characteristics analysis.

 

Aluminum alloy is the most widely used metal in all walks of life, second only to steel in output. Aluminum alloy forging has a series of excellent properties. The metal structure of aluminum alloy can be changed after forging and pressing, which can effectively improve the properties of aluminum alloy.

 

(I) Aluminum alloy forging process:

 

Forging and pressing production occupies a very important position in the industrial industry, aluminum alloy is also a commonly used material in forging, all kinds of forging can be forged with low carbon steel, can be produced with aluminum alloy forging. Most of the alloy forging parts are safe parts and are manufactured in large quantities, so the inner quality requirements of aluminum alloy materials are very high.

 

Forging aluminium alloy parts generally go through the following main manufacturing process: alloy melting - casting - extrusion - forging - heat treatment - mechanical processing. Alloy melting composition ratio, degassing, filtration, casting inverse segregation, extrusion process quality, forging (aluminum alloy forging) metal streamline, heat treatment temperature, time, grain size control, dimensional accuracy, etc., require very systematic process control to achieve stability.

 

(ii) Features of aluminum alloy forging:

 

First of all, the internal organization is fine, uniform, without defects, and its reliability is far away. Can be processed into various shapes of complex high-precision forging, machining allowance is small, only for aluminum alloy tensile thick plate processing allowance of about 20%, greatly saving time and cost. Secondly, good thermal conductivity. The forging temperature range is narrow, and the initial and final forging temperature requirements are strict. The performance characteristic of hot die forging is that aluminum alloy does not produce isomerism transformation, which mainly depends on the correct control of forging mechanical parameters to improve the metal structure, so that the metal flow line evenly and continuously distributed along the forging shape to improve the mechanical properties.

 

Third, the forging aluminum wheel has high density, no loose, pinhole, no air hole on the surface, and has good surface treatment performance. Uniform coating, high adhesion, color harmony beautiful. Wrought aluminium wheels have good machining properties. It can be seen that the forged aluminum wheel has light weight, high specific strength, toughness and fatigue resistance and corrosion resistance excellent, good thermal conductivity, easy to mechanical processing.
