主要介绍板料在拉深成形过程中单位压边力值对板料成形性能的影响。研究方法采用仿真技术 ,指出板料在成形过程中如按最初设定的单位压边力值进行成形 ,那么 ,板料成形过程中单位压边力值将逐渐增大 ,严重影响板料成形极限。如果采用控制板料在成形过程中压边圈下坯料的单位压边力值 ,将提高板料成形极限。其结论为生产现场提高板料成形性能和表面质量提供了一种可实施的方法。
The paper mainly introduces the influence of the unit blank holder force on the sheet forming performance during the drawing process. The research method uses the simulation technology to point out that the sheet blank forming process according to the initial set of blank holder force value forming, then the blank forming unit blank holder force value will gradually increase, seriously affecting the sheet forming limit . If you use the control plate blank forming blank holder in the process of blank per unit value, will increase the sheet forming limit. The conclusion provides an implementable method for improving sheet formability and surface quality at the production site.
