<p>The method according to the invention for riveting or punching by means of a riveting or punching device (8), having a pick-up device (4) and a male die (3) guided by a pick-up device (4), both of which in each case can be moved towards a female die (5) or a workpiece (6), wherein female die (5) and riveting or punching device (8) are connected to one another via a counterforce structure (9), is characterised in that the relative movement between pick-up device (4) and counterforce structure (9) is measured by a first sensor (1) and the relative movement between counterforce structure (9) and male die (3) is measured by a second sensor (2) and the depth of the riveting or punching is adjusted with the aid of the two measured values. The associated device allows fast, accurate detection of the thickness of a workpiece (6) and precise punching or riveting with constant predetermined depth irrespective of variations in the quality of the material or other parameters, which can result in deformations of the counterforce structure (9) during the punching process.</p> |
