METHOD AND DEVICE FOR CONNECTING OVERLAPPING FLAT PARTS

摘要

The invention relates to a method for connecting overlapping flat parts in a mechanical joining process, for example for connecting panels, using a mould stamp (1a) and a matrix which is provided with a recess, the parts to be connected being placed between the mould stamp and the matrix. The invention is characterized in that the active axial advancing movement of the mould stamp (1a) is impressed with a tumbling motion throughout the entire joining process or during a part of the joining process and will a variable stamping force (F) which is dependent on said tumbling motion, in or to produce a flow of material that is oriented towards the undercut (6). The invention also relates to a device for carrying out the inventive method.
