针对目前国内爪极锻造成形困难,设备吨位大,模具寿命低等问题,在分析其关键技术难点的基础上,制定了爪极精密成形新工艺:闭式热模锻正挤成形。利用DEFORM-3D进行了数值模拟分析,并采用专用模具进行了新工艺的实验研究。结果表明:新工艺大幅降低了爪极零件的成形载荷,从而减少了生产工序并提高了模具寿命,适合大批量生产。

Aimed at present domestic problems in the forging process of claw pole,such as insufficient corner filling,excessive forming force and short life of dies and on the basis of analyzing the claw pole,a new process named as closed hot die forging direct extrusion process for claw pole was constituted.The numerical simulation using DEFORM-3D and the special mould were used in the forging experiment in order to check the new process.The results show that new technology has greatly reduced the forming force and thereby the production procedure is reduced and the die life is improved for the mass production.
