Problems solved by technology

In addition, in this method, the sheet metal part of the body is in contact with the two dies, the die and the punch, in each case over a particularly large area, which leads to a particularly large thinning of the sheet metal part material

Embodiment Construction

[0031] Identical or functionally identical elements have the same reference symbols in the figures.

[0032] figure 1 A forming tool 1 is shown schematically, which comprises a first forming part 2 , in particular formed as a punch, and a second forming part 3 , in particular formed as a die. Between the first and the second profiled part 2 , 3 there is a component 4 which is to be given an edge 5 by means of the profiled tool 1 . Edge 5 is a curvature with a particularly small radius, such as edge radius 6 . If the component 4 is a skin component of a motor vehicle, the appearance of the motor vehicle can be given a special, eg sporty character, by means of the edge 5 . This means that the edge 5 can be a so-called characteristic edge. Furthermore, the edge 5 can have a technical function, for example as a flow guide for water flowing along the outer shell of the motor vehicle. Such a characteristic edge can extend over a plurality of adjacent shell components on the skin...

Abstract

The invention relates to a shaping tool (1) and to a method for producing an edge (5) on a component (4), comprising a first and a second shaping element (2, 3) moveable from an open position into a shaping position, as a result of which, in a pressing region (9) of the shaping tool (1), the component (4), which can be supported on both shaping elements (2, 3) while it is moved in the pressing region (9), can be pressed into a negative mould (10), formed in the second shaping element (3), for the edge (5) that is to be produced. According to the invention, a shaping surface (11) of the first shaping element (2) in the pressing region (9) has an allowance element (12) which projects over base surface regions (13) of the shaping surface (11) adjacent to the allowance element (12), as a result of which the component (4) can be distanced from the second shaping element (3) at least in the shaping position in a sub-region (15) adjacent to the pressing region (9). The invention also relatesto a method for producing a shaping tool (1).

Description

technical field [0001] The invention relates to a forming tool for producing edges on components according to claim 1 . Furthermore, the invention relates to a method for producing an edge on a component according to claim 4 . The invention also relates to a method for producing such a forming tool according to claim 5 . Background technique [0002] The geometry of motor vehicle skin components decisively influences the appearance of the motor vehicle, which are currently generally produced by forming, for example, from thin aluminum sheets or steel sheets of original thickness. In particular, these housing components can have at least one curvature with a particularly small radius, a so-called sheet metal profile edge or sharp edge. Such a bend is referred to as a sheet metal profile edge in the visible region of the housing component. The sheet metal profiled part edge usually runs in the region of the freeform surface of the housing component. In addition, the sheet ...
