基于Dynaform的微型轴承浪形保持架冲压成形工序仿真分析

Simulation Analysis on Stamping Forming Process for Ribbon Cage of Miniature Bearings Based on Dynaform

针对微型轴承浪形保持架成形的不确定性,工件的内径检测困难,成形件的质量不易控制的问题,采用板料成形数值仿真软件Dynaform对浪形保持架的成形过程进行模拟仿真和优化,分析工艺参数和模具结构参数对成形件质量的影响,为浪形保持架加工工艺和质量控制提供一种新的方法。

For miniature bearing, it is difficult to detect the ribbon cages forming process and inner diameter, and the quality of the formed parts is not easy to control. In order to solve these problems, the sheet metal forming numerical simulation software Dynaform is used for simulation and optimization of the ribbon cage stamping forming process, and the effect of process parameters and mold structure parameters on forming parts quality are analyzed. This research pro- vides a new clue for the ribbon cage processing technology and quality assurance.
