Definitions
- the invention relates to a method and a device for bending corrugated or profiled sheets, in particular trapezoidal profiles with a side height of more than 45 mm.
- DE-OS 27 27 287 it is known from DE-OS 27 27 287 to bend the sheet profile in that the side faces of the sheet profile are freely formed when an upper and lower bending means are moved together. This is intended to ensure that only a relatively simple edging movement can be carried out with the machine and the material is displaced freely in the side surfaces.
- the object of the present invention is to avoid the disadvantages described and to bend a sheet metal profile with uniformly shaped side faces of any shape, in particular with profile heights of more than 45 mm.
- this is achieved in that for the bending of corrugated or profiled sheets, the profiling of which consists of roof, floor and side surfaces, the side surfaces are deformed simultaneously with the edges of the roof / floor surfaces with a variable pressing force.
- Two levers movable in different directions are used in the side walls, the geometric path of which in the bending zone corresponds to one from top to bottom (vertical) and one from inside to outside (horizontal): movement.
- the required material displacement is generated by the integrating motion sequence.
- bulges that are uniformly curved inwards or outwards ((continuously) or bulges that are curved inwards in the roof and floor surfaces and outwards in the side surfaces are continuous.
- the shape of the bulges depends on the course of the process, specifically the shape that continuous bulges are generated by a fitting inserted from the inside and acting in the horizontal and vertical directions. while the discontinuous bulges are achieved by simultaneously acting but opposing deformation of the roof / floor surfaces and the side surfaces.
- the method according to the invention can also be used to produce discontinuous curvatures in the surfaces of the trapezoidal profiles, which are bulged very deeply and nevertheless have a uniform shape. This even applies to relatively soft sheet material, e.g. Aluminum in a soft condition, since the wavy surface texture is avoided by using geometrically defined tools.
- relatively soft sheet material e.g. Aluminum in a soft condition
- the method according to the invention aims to use a variable counterhold to the pressing pressure of the bending means in the profile interior of the sheet profile to be deformed, which leads to a defined bulge of the sheet profile due to the arrangement of the axes of rotation and the geometric configuration of the variable counterpart.
- a firm hold in the lower tool is effected by two tool webs (8) arranged parallel to one another and adapted to the profile interior. These webs also serve to mount the levers (6a, 6b), - which cause the variable counterhold.
- the shape of the lever (6a, 6b) is arbitrary, it only has to be selected symmetrically to the two axes of rotation 11, 12. Furthermore, for easy movement of the levers 6a, 6b, the lever arms 13, 14 should be dimensioned sufficiently long, at least sufficiently long, in order to do justice to the ratio of the vertical to the horizontal sheet metal bulge.
- a notch or depression must be incorporated in the tip 15.
- the open levers 6a, 6b are shown in dashed lines in FIG. 1a.
- F ig. 1b shows the lower part of the device according to the invention in plan view. It can be seen that the levers 6a, 6b are pyramid-shaped, as a result of which the shape of the bead produced is geometrically predetermined.
- the upper tool consists of two tool webs 9a, 9b, in which the outer contour of the profile is incorporated.
- the bending sword 7 is located in the middle of these two webs 9.
- FIG. 2 shows how the tool webs 9a, 9b and the levers 6a, 6b work together.
- the two tool webs 9 slip over the fixed webs 8 lying in the same alignment underneath and hold the profile to be bent in its shape.
- the bending sword arranged in the middle of the upper tool presses on the profile which lies on the webs 8.
- the profile surface 1 is compressed, the levers 6 underneath are inevitably pressed outwards on both sides, and the bending process is thus carried out simultaneously on the surface 1 and the two side surfaces 3.
- Fig. 3 a sheet profile produced with the device according to the invention is shown.
- the discontinuous curvatures at the kink point of the sheet can be seen.
- more or less sharp bends can be made.
- the number of bending processes is not limited, so that any radius of curvature can be generated.
- the lower and upper tools can of course also be interchanged, and profiles can also be bent in a negative or positive plane.
- Fig. 4 shows a sheet metal profile manufactured according to the invention with continuous bulging of the side and roof / floor surfaces. This profile was created by inserting the counter-holding means or shaped piece into the interior of the profile and pressing it out in the vertical direction. It can be seen that, similar to a stovepipe with a continuous rib, a soft and rounded transition zone between the sheet profile and the bulge has been created.
