Abstract (en)
[origin: WO2014202271A1] The invention relates to a device for producing at least one undercut in a slotted or closed profiled sheet section, comprising a core (1) that is introduced into the profiled sheet section or is used as a support core for a semifinished sheet metal product from which the profiled sheet section is produced. The device is characterized in that the core (1) has at least two outer core sections (1.1, 1.2), at least one of which has at least one depression (2, 3) or at least one projection for shaping an undercut into the profiled sheet section, and an inner core section (1.3) is arranged between the at least two outer core sections (1.1, 1.2), said inner core section being movable relative to the outer core sections (1.1, 1.2) and having at least one effective surface (1.31, 1.32) which is designed in the shape of a cam or in an inclined manner relative to the outer core sections (1.1, 1.2) in a specified movement direction (P1) of the inner core section (1.3). The outer core sections (1.1, 1.2) are moved away from each other by moving the inner core section (1.3) in the specified movement direction (P1) relative to the outer core sections, and the outer core sections are then moved towards each other upon moving the inner core section (1.3) in the opposite movement direction (P4).
