摘要: 监测冲压件成形质量变化,对于避免缺陷产生与资源浪费,实现绿色制造至关重要。模具的封闭性和环境噪声干扰导致图像、振动及压力分布等数据难以准确获取,影响冲压件成形质量的监测精度。已有研究指出,易采集且抗干扰的冲压力在冲压深度上的积分(即工艺能量)与冲压件的厚度变化率之间存在定量变化关系。为此,本文提出了一种通过颜色与深度表征并监测冲压件厚度变化率的冲压工艺能量图谱。图谱以冲压深度与工艺能量分别作为横、纵坐标,将测量厚度变化率根据对应坐标分布于图谱之上。考虑有限测量数据对数据插值预测数据精度的限制,应用一种数据空间混合策略,将数据插值预测的厚度变化率与仿真厚度变化率进行空间加权混合,实现图谱的精确填充与着色。进一步根据厚度变化率阈值曲线,完成图谱质量区域的划分。类车门内板件厚度变化率监测结果显示,图谱监测的平均绝对百分比误差不超过5%,对破裂与起皱的识别准确率超90%。应用图谱进行工艺控制的结果显示,冲压件的最大减薄率降低了14.56%,有效地避免了冲压件的破裂。所提出的冲压工艺能量图谱可实现冲压件成形质量的精确监测,助力高质量、零缺陷生产。

Abstract: Monitoring the part quality variation is essential to avoid defects and resource waste for green manufacturing achievement. However, it is difficult to obtain accurate images, vibration, pressure distribution, and other data for the accurate monitoring of the forming quality of stamping parts due to the closed mold and noisy production environment. Existing efforts indicated that the part thickness variation ratio varies quantitatively with process energy, which is the accumulation of punch force over the stamping depth, and it is easy to collect and anti-interference. In this context, a stamping process energy map is proposed to characterize the thickness variation ratio by color and its intensity. The stamping depth and process energy are set as the horizontal and vertical coordinates of the map, respectively. A data interpolation technique is applied to interpolate the measured thickness variation ratio data located in the map. Considering the limitation of finite measurement data on the accuracy of interpolation data, a data spatial blending strategy that weights and blends the interpolated and simulated thickness variation ratio data to fill and color the map followed by the quality zone division according to the threshold curve of thickness variation ratio. To validate the effectiveness, the map was applied to form a downscaling part of a car door. The mean absolute percentage error of the monitored thickness variation ratio was within 5%. The crack and wrinkle identification accuracy is up to 90.63%. The results of applying the map to stamping process control showed a 14.56% reduction in the maximum thinning ratio of the part, which effectively prevents cracking. The proposed stamping process energy map assisted in accurate part quality monitoring and quality improvement in stamping.
