(1) Aluminum alloy forging process:
Forging production plays an important role in the industrial industry. Aluminum alloy is also commonly used in forging. Any forging that can be forged with low carbon steel can be forged by aluminum alloy. Most of the alloy forged parts are safety parts and are mass-produced. The inherent quality requirements of aluminum alloy materials are very high.
Forged aluminum alloy parts generally undergo the following main manufacturing processes: alloy smelting - casting - extrusion - forging - heat treatment - machining. Alloy smelting into distribution ratio, degassing, filtration, casting reverse segregation, extrusion process quality, forging (aluminum alloy forging) metal flow lines, heat treatment temperature, time, grain size control, dimensional accuracy, etc., requires a very systematic process Control can be stabilized.
(2) Characteristics of aluminum alloy forging:
First of all, the internal organization is fine, uniform, and flawless, and its reliability is far. It can be processed into high-precision forging with various shapes and complex shapes. The machining allowance is small, only about 20% of the processing capacity of aluminum alloy tensile slabs, which greatly saves man-hours and costs. Secondly, the thermal conductivity is good. The forging temperature range is narrow, the initial and final forging temperature requirements are strict, and the performance characteristics of the heating die forging are that the aluminum alloy does not produce the homologous isomerization transformation, and the metal structure is improved by the correct control of the forging mechanical parameters, so that the metal flow line is uniformly and continuously along the forging Shape distribution to improve mechanical properties.
Third, the forged aluminum wheel has a high density, no looseness, pinholes, no pores on the surface, and good surface treatment properties. The coating is uniform, the bonding force is high, and the color is beautiful. Wrought aluminum wheels have excellent machinability. It can be seen that the forged aluminum wheel has the advantages of light weight, high specific strength, excellent toughness and fatigue resistance and corrosion resistance, good thermal conductivity and easy mechanical processing.
