在机械制造过程中,类似图1的工件很多。生产此类工件的一般方法,是制作专用模具来卷制。当工件的批量大,且尺寸A值小时,做模卷制比较合适,但当工件批量小,且尺寸A值大时,则成本过高而得不偿失。为此,我们在生产实践中,摸索出一套用折边机折卷薄板(板厚B≤3mm)筒形工件的方法。其步骤如下: In the mechanical manufacturing process, a lot of workpieces similar to Figure 1. The general method for producing such workpieces is to make a special mold for rolling. When the workpiece batch, and the size of A small value, it is more appropriate to do roll mode, but when the workpiece is small, and size A value is large, the cost is too high and not worth the candle. To this end, we in the production practice, worked out a set of folding machine with a folding machine (plate thickness B ≤ 3mm) cylindrical workpiece method. The steps are as follows:
