Embodiment Construction
[0025] The device shown in the drawing is used for producing undercuts in slotted or closed hollow profiles made of sheet metal. The device comprises a three-part core 1 which may also be referred to as a core unit or a detachable core.
[0026]The core unit 1 is elongated and comprises two outer core parts 1.1 and 1.2 each having a plurality of recesses 2 and 3 for closing, for example Inwardly oriented undercuts are formed in sheet metal profiles. Between the two outer core parts 1.1 and 1.2 is arranged an inner core part 1.3 which is movable in a linear manner relative to the outer core parts 1.1 and 1.2 and which has corrugated working surfaces 1.31 and 1.32. The inner surfaces 1.11 and 1.12 of the outer core parts 1.1 and 1.2 facing the running surfaces 1.31 and 1.32 of the inner core part 1.3 are likewise of corrugated configuration. The corrugated running surfaces 1.31, 1.32 of the inner core part 1.3 and the inner surfaces 1.11, 1.21 of the outer core parts 1.1, 1.2 ...

The invention relates to a device for producing at least one undercut in a slotted or closed sheet metal profile, comprising a core (1) which is inserted into the sheet metal profile or used as sheet metal for semi-working The supporting core of the product, the sheet metal profile, is made of this semi-finished sheet metal product. The device is characterized in that the core (1) has at least two outer core parts (1.1, 1.2), wherein at least one outer core part has at least one recess (2 , 3) or at least one protrusion; and an inner core part (1.3) is arranged between at least two outer core parts (1.1, 1.2), the inner core part can be relative to the outer core part ( 1.1, 1.2) move and have at least one working surface (1.31, 1.32) designed to be cam-shaped or relative to the outer core part (1.1 , 1.2) Tilt. By moving the inner core part (1.3) relative to the outer core part (1.1, 1.2) in a predetermined direction of movement (P1) such that the outer core parts (1.1, 1.2) are moved away from each other, and subsequently, by moving in the opposite direction of movement ( P4) Moving the inner core parts (1.3) such that the outer core parts move towards each other.
Description
technical field [0001] The invention relates to a device for producing at least one undercut in a slotted or closed sheet metal profile, the device comprising a core which is inserted into the sheet metal profile or used as a sheet metal product for semi-processing The supporting core, the sheet metal profile is made from this semi-processed sheet metal product. Background technique [0002] During the manufacture of at least partially closed profiles (grooved profiles) or such semi-finished products, continuous forming methods or intermittent forming methods can be used. For example, continuous forming is performed by roll forming. Intermittent roll forming is preferred when continuous roll forming cannot be applied due to the complex profile or geometry of the semi-finished product. For example, in the discontinuous production of at least partially closed profiles or semi-finished products, so-called U-O forming methods are known. [0003] Prior art includes the use of ...
