Description

technical field

[0001] The invention relates to the technical field of metal precision forming, in particular to the technical method of precision forging of automobile claw poles. technical background

[0002] Claw poles are key components in automotive alternators. It has many specifications, but its shape is similar, but its size is different. Due to the high complexity of its geometric shape and the importance of performance, the difficulty of forging and forming is increased.

[0003] The shape and structure of such forgings are very complex ( image 3 , Figure 4 ): The middle part is a boss with a hole, and there are six thin and evenly distributed transverse webs on the end of the boss, and six vertical claws with complex shapes are evenly distributed on the end of the transverse web. Except for machining, the rest are all black leather, so forging is very difficult.

[0004] In the prior art, there are many methods for forming claw pole forgings, but each has it...
