DEVICE FOR JOINING METAL SHEETS TOGETHER

摘要

The invention relates to a device for joining metal sheets together, comprising a punch and a die with elastically deflectable cutting parts. The dimensions of the punch, on the one hand, and of a closed contour of the die, on the other hand, define a joining region, such that none of the sheets is cut through and the joint has essentially isotropic tensile strength in all directions parallel to the sheets. The joint is also aesthetically pleasing on both sides. ……
