Today, aluminum alloy forging manufacturers will mainly introduce aluminum alloy forging technology, which includes aluminum alloy free forging technology, aluminum alloy forging technology, aluminum alloy forging heat treatment, commonly used aluminum alloy forging equipment, new aluminum alloy forging technology, and information technology. Forging is used in the process of aluminum alloy processing, so what is aluminum alloy forging?
All aluminum light alloy forging is a forging process that utilizes the plasticity of materials and external forces to produce plastic deformation, resulting in the desired shape, size, and certain structural properties. Advantages: The forging has a dense and uniform structure inside, and its performance is higher than that of die-casting, cutting, and welding parts. Disadvantage: Requires significant deformation force. What everyone needs to pay attention to is forging technology and classification, mainly divided into warm forging technology and cold forging technology.
Warm forging introduction: Warm forging is a chip free plastic forming process developed on the basis of cold forging. The temperature is usually above room temperature and below the recrystallization temperature. Black metal: 200~850C; Non ferrous metal: Room temperature~350 C
The characteristics of warm forging: It combines the advantages of cold forging and hot forging, while also reducing their respective disadvantages.
Compared to cold forging
1. Warm forging blanks have low deformation force and are easy to form;
2. The deformation amount is large, which can reduce the number of processes, mold costs, and press tonnage, and the mold life is also higher than that of cold forging;
3. There is no need for pre softening of the raw material and annealing between processes, which makes continuous production easier than cold forging.
Introduction to Cold Forging: Cold forging technology belongs to the volume plastic forming of metals at room temperature. There are two main forming methods: cold extrusion and cold heading extrusion. For example, screws, rivets, etc. are cold heading extruded. Difference: The Z dimension of cold extruded parts is basically the same as the outer diameter of the blank; The Z dimension of the upsetting or upsetting workpiece is larger than the outer diameter of the blank
The characteristics of cold forging: high material saving and part quality, including high dimensional accuracy, low surface roughness, can reduce or eliminate machining and grinding processes, and sometimes can eliminate heat treatment.
