浅析U形件回弹

Analysis of U-Shape Part Springback

回弹是冷冲压成形过程中不可避免的物理现象,一直是影响、制约模具和制件质量的重要因素。回弹给模具设计和制造带来了很大的困难,常常需要采用反复试模、修模及成形后人工矫正的方法才能制造出符合要求的制件。通过分析金属板材弯曲回弹的现象、影响因素,总结了控制弯曲回弹的具体措施和方法,解决了实际生产中的问题。

The springback is inevitable physical phenomena m the corn iormmg springback has been, an important factor restricting the die and product quality. The springback brought great difficulties to the die design and manufacturing, often require repeated test die, repair die and after forming artificial correction method in order to manufacture products to meet the requirements. Through the analysis of sheet metal bending springback phenomenon, influencing factors, summed up the controlled bending springback specific measures and methods to solve problems in the actual production.
