| Abstract: | The technology of precision cold forging has great advantages in the field of motor's product.A successful application of this technology in producing starting gear is introduced in this article.The structure and characteristic of the mould for motor's starting gear is showed in detail.The methods that can prolong the mould life is put forward,of which the most important one is that the punch can be designed as the type of assembly,and the pre stress can be added.By this way,the strength of the mould is improved greatly. |
