Description

Technical Field

[0001] The present invention relates to the field of forging technology, in particular to a precision forming manufacturing process for aluminum alloy fasteners. Background Art

[0002] Forging is a combination of forging and stamping. It is a forming method that uses the hammer, anvil, punch or die of a forging machine to apply pressure to the blank to cause it to deform plastically, thereby obtaining a part of the desired shape and size. During the forging process, the blank undergoes obvious plastic deformation as a whole, and there is a large amount of plastic flow; in the stamping process, the blank is mainly formed by changing the spatial position of the area of ​​each part, and there is no plastic flow over a large distance inside it. Forging is mainly used to process metal parts. Common fasteners such as bolts are all forged by forging machines.

[0003] The processing of bolts includes multiple steps, such as cutting, bolt head forming, screw forming, thread rolling, rust prevention and other steps. Among them, the bolt head forming and screw forming processes are both forged by a forging press. Since the bolt head forming and screw forming correspond to different forming dies, during actual processing, after the forging press forges the bolt head, the bolt is transported to another forging press for forging the screw part, which increases the feeding, discharging and conveying time of the bolt and reduces the bolt forming efficiency.
