Embodiment Construction

[0017] The tool 100 comprises a tool lower part 110 with a tool active surface 112 and a tool upper part 120 running opposite it with a tool active surface 122 . By lowering the tool upper part 120 , the sheet material M between the tool active surfaces 112 and 122 can be deformed in a known manner. The illustration shows the final state of the deformation of the sheet metal, wherein the tool upper part 120 is at the dead center of movement of its lower end.

[0018] In order to produce a pronounced sheet-metal profile edge in the sheet metal M, the lower tool part 110 is provided with a tool edge 115 in the region shown, and the upper tool part 120 is provided with a notch-shaped tool recess opposite the tool edge 115. Slot 125. The tool recess 125 is contained in an exchangeable tool insert 127, wherein the tool insert 127 can be designed as a multi-part, as indicated by dashed lines. Likewise, the tool edge 115 can also be embodied on an exchangeable tool insert. The too...

Abstract

The invention relates to a tool (100) for producing a sheet-metal profile part having a sheet-metal profile part edge, the tool (100) having a first tool part (110) and a second tool part movable relative to the first tool part Parts (120), wherein these tool parts (110, 120) have tool active surfaces (112, 122) for shaping, and the tool active surface (112) of at least one tool part (110) in these tool parts is designed There is at least one tool edge (115) which produces the edge of the sheet-metal profile, and the tool active surface (122) of the other tool part (120) is formed with an opposite tool recess (125). In order to form a clear sheet metal profile edge, it is provided here that the tool active surface (112) is locally provided with a planar allowance (A) on both sides of at least one such tool edge (115), so that the sheet metal (M) During the deformation, it is pressed into the opposite tool groove ( 125 ), and the sheet-metal profiled part edge can be formed on one side of the tool groove ( 125 ).

Description

technical field [0001] The invention relates to a tool for producing a sheet metal profile by forming a sheet metal, wherein the sheet metal profile to be produced has at least one distinct sheet metal profile edge. Background technique [0002] Within the framework of the invention, a pronounced sheet-metal profile edge is to be understood as a planar transition formed on the sheet-metal profile with an extremely small edge radius, wherein the sheet-metal profile edge refers to the subsequent assembly of the sheet-metal profile Or occlusions should be in the visible part area. The sheet-metal profiled part edge can have a spatial course extending through the sheet-metal profiled part. Such sheet metal profile edges are sometimes also referred to as design edges, and this is not entirely true, since such sheet metal profile edges can also have technical functions and serve, for example, as stiffening elements, air duct elements and guides. Flow elements and similar element...
