Application of Aluminum Alloy Precision Die Forging

1. Cold precision forging directly forges unheated metal materials, mainly including cold extrusion and cold head extrusion. Cold precision forging technology is more suitable for a variety of small batch production, mainly for the manufacture of automobiles. Various parts of motorcycles and some toothed parts.

2. Hot precision forging mainly refers to the precision forging process above the recrystallization temperature. The hot precision forging process mostly adopts closed die forging, which requires high precision of the mold and equipment. The volume of the billet must be strictly controlled during forging, otherwise a large pressure will easily be generated inside the die. Therefore, when designing closed die forging dies, the principle of shunt pressure reduction is usually used to solve this problem. At present, most of the spur bevel gears used in trucks in my country are produced by this method.

3. Temperature forging is a precision forging process performed at an appropriate temperature below the recrystallization temperature. But the forging temperature of temperature forging is divided into narrow. The mechanics of the die material and the die itself are very demanding, usually requiring the use of special high-precision forging equipment. The temperature forging process is generally more suitable for mass production, forging medium yield strength materials.

4. Composite forming mainly combines cold, warm, hot and other forging processes to learn from each other’s strengths to achieve the desired effect. Composite forming is a standard forging method for high-strength components such as various gears and pipe joints.

5. Block forging is a molding process in which one-way or two-way double-action extruding metal is formed in a closed die by one or two punches to obtain flash-free precision forgings. Mainly used in the production of bevel gears. Automobile constant velocity universal joint star sleeve. Pipe joints. Cross shaft. Bevel gears and other products.

6. Isothermal forging refers to the die forging of the blank at a constant temperature. For deformation temperature sensitive. Difficult-to-shape metal materials and parts such as titanium alloys, aluminum alloys, thin webs, and high ribs.

7. Diverter forging is the establishment of a diverter cavity or diverter channel of material in the blank or forming part of the die to fill the material. Split forging is mainly used for cold forging forming process of spur and helical gears.
