1.负回弹弯曲成形 图1所示工件是利用负回弹弯曲成形原理来加工的。该件材料为08F,料厚δ为1.5mm,要求工件在成形后有少量的负回弹。
1. Negative Rebound Bending Forming The workpiece shown in Figure 1 is machined using the principle of negative rebound bending. The material is 08F, material thickness δ is 1.5mm, requiring a small amount of negative rebound after forming the workpiece.
