| 摘要 |
The invention relates to a clinching tool (20) for establishing a load-bearing, or supporting, or stable connection of a first metal workpiece (11) to a second metal workpiece (12). The clinching tool (20) comprises a male die (20) and a female die (30), which together form and join a clinching connection (13) connecting, or permanently connecting, the first metal workpiece (11) to the second metal workpiece (12), via local, plastic deformation or reshaping. The male die (20) has a die having a flank (25) disposed concentrically to the rotational axis (24). The flank (25) has a face surface (23) that is positioned perpendicular to the rotational axis (24). The flank (25) is conically shaped at least in the lower transitional region (21) to the face surface (23) and has a flank angle (W, W1, W2) that is smaller than, or equal to, 10 degrees, preferably smaller than, or equal to, 5 degrees. |
