发明名称 METHOD FOR CLINCHING THICK METAL WORKPIECES, USE OF A CLINCHING TOOL, AND STEEL STRUCTURAL ELEMENT PRODUCED ACCORDINGLY.
摘要 The invention relates to a method for the production of a load-bearing structural steel connection, wherein a clinching connection (13) is formed by means of a male die (20) and a female die (30) using local deformation, the connection connecting a first metal workpiece (6.1, 6.2) to a second metal workpiece (6.3, 6.4). For this purpose, the first metal workpiece (6.1, 6.2) and the second metal workpiece (6.3, 6.4) are first placed on top of each other on a processing surface of the female die and aligned. Subsequently the die of the male die is applied and lowered into the two metal workpieces (6.1, 6.2; 6.3, 6.4) placed on top of each other until the clinching connection (13) has been formed by plastic deformation. The first metal workpiece (6.1, 6.2) has a first workpiece thickness (tl), and the second metal workpiece (6.3, 6.4) has a second workpiece thickness (t2) that together result in a total workpiece thickness (tt), which is greater than 8 mm. The die is configured in a rotationally symmetrical manner with regard to the rotational axis (24) thereof and has a conically shaped transitional region (21, 22) tapering at an angle (W, W1, W2) in the lowering direction of the die.
