AI Technical Summary

Technical Problem

Existing technologies are difficult to effectively reduce the unevenness of metal sheets, especially the leveling methods for hyperbolic deformation, which are costly and inefficient, require large investments in specialized equipment, and conventional methods cannot effectively eliminate bulging phenomena.

Method used

A composite process combining a skin stretching machine and a single-curvature surface mold with a three-axis rolling machine is adopted. Through stretching and rolling processes, CNC equipment is used to achieve plastic deformation of metal sheets and eliminate unevenness in the bulging area.

Benefits of technology

It achieves low-cost and efficient reduction of unevenness in metal sheets, avoids the high investment in specialized equipment, and is applicable to metal sheets of different thicknesses and widths, with significant results.

Abstract

本发明提供了本发明提供一种降低金属板材不平度的塑性加工方法,利用蒙皮拉伸机和单曲率型面的模具对金属板材进行拉伸,鼓动区域的材料得到充分拉伸,直至鼓动区域材料达到塑性变形阶段,完成该工序可消除金属板材鼓动,为方便开展反向卷平工序,对拉伸过程中所使用的工艺余量及成形过渡区进行切除;利用三轴滚圆机对单曲率金属板材进行反向滚圆,使金属板材趋于平整。
