具体实施方式
下面结合附图对本发明作进一步说明。
如图1和图2所示，本发明包括波纹钢板1、上辊轴2、下辊轴3、滚齿4、齿顶5、齿谷6、冲头7、孔槽8和连接孔9。如图1所示，在垂直于波纹钢板1的前进方向上设有两根辊轴，上辊轴2和下辊轴3。两根辊轴通过电机和齿轮等动力机构驱动旋转(图中未画出)，且旋转方向相反，上辊轴2和下辊轴3沿波纹钢板1的上下排列，且两根辊轴的轴线平行，其形成的平面垂直于波纹钢板1的平面。两根辊轴的旋转方向相反，每根辊轴的四周均匀设置有一圈滚齿4，包括齿顶5和齿谷6。齿顶5及齿谷6沿辊轴的周向均匀分布，且间距相等。齿顶5和齿谷6均为圆弧形，圆弧的轴心线与辊轴的轴线平行，且与辊轴轴线的距离相等。齿顶5及齿谷6的圆弧形状与波纹钢板1的波顶及波谷的形状相同。辊轴和滚齿均采用钢制材料制成。
如图2所示，在上辊轴2和下辊轴3的齿顶5及齿谷6上分别设置有冲孔用的冲头7或孔槽8，在上辊轴2或下辊轴3上的冲头7与孔槽8均在齿顶5及齿谷6上间隔分布，且位于上下辊轴的冲头与孔槽对应。比如，上辊轴2齿顶上的冲头与下辊轴3齿谷上的孔槽相对应，上辊轴2齿谷上的孔槽与下辊轴3齿顶上的冲头对应。孔槽8的宽度要大于冲头7的宽度。当波纹钢板1进入上辊轴2与下辊轴3之间的滚齿后，带有冲头7和孔槽8的上下滚齿逐渐旋转致压合，冲头7冲孔完成，在波纹钢板1上冲出连接孔9，冲下来的孔片落在孔槽8内，冲孔完成，待该波纹钢板1经辊轴旋转转移出上下辊轴后，连接孔9成型完成，孔槽8内的孔片随着辊轴的旋转掉出。
