如图1所示的不锈钢炊具中,经常需要进行卷边。卷边工艺是生产中的关键工序,所以不可忽视。由于不锈钢价格较高,废件不能回炉重炼,所以在生产中,无论如何也不允许出现废品。过去,我们在卷边前的工序是拉深和切边,用这种工艺生产,出现的废品较多:如要求卷边朝上,而在卷边过程中,却出现一段卷边朝下的现象(见图2)。经过反复研究认为:尽管卷边工件的大小、转速与卷边轮的大小和进给速度有关,但在卷边的一瞬间,工
In the stainless steel cookware shown in FIG. 1, curling is often required. Crimping process is the production of the key processes, it can not be ignored. Due to the high price of stainless steel, scrap can not be re-refining, so in production, in any case is not allowed to appear scrap. In the past, the process before the crimping process was deep drawing and trimming. In this process, more scrap was produced: if the crimp was required to be facing upwards while the crimping process was followed by a crimp down Phenomenon (see Figure 2). After repeated studies that: Although the size of the curling workpiece, the speed and the size of the curling wheel and the feed rate, but in the curling moment, workers
