Improvement of the reverse side pressure roller of thin plate cylinder

When making a bucket or the like with a thin plate, in order to combine with the bottom and increase the strength, it is necessary to turn out an edge and press a convex line on the lower side (see Fig. 1). Small and medium-sized batch production is generally pressed by rollers on the crimping machine, which not only has low efficiency, but also the seam of the cylinder is easy to loose, and the cylinder is out of round after pressing, and an additional shaping process is needed. To this end, we have designed a composite pressure roller that is added to the baffle
