发电机转子护环变形强化模具的研究

Research on deforming strengthened die of the generator rotor retaining rings

对护环液压胀形模具加载冲头的工作面形线和减力导柱的尺寸进行了讨论。对内增压扩胀护环的装置和双锥面楔块扩孔模具进行了研究。围绕生产中出现的问题 ,提出了改进护环液压胀形和楔块扩孔的措施。

In this paper, two main parameters of the hydraulic expanding die of retaining rings, the working face outline of the pressed punch and the dimensions of the load-reducing guide post were discussed. The die and eqiupment of internal pressurized expanding retaining rings and double cone wedge-reaming die were also studied. According to the problems encountered during production, the retaining ring expansion and wedge reaming were modified, and it will have an important significance in improving production level of retaining rings.
