Definitions
- the invention relates to a method for producing a longitudinally slotted hollow profile, in particular as a preliminary product of a longitudinally welded hollow profile - from a flat sheet metal plate which consists of several longitudinal sections with different cross sections, of which at least one section increases or decreases over its length.
- Hollow sections of this type can be produced in various ways.
- the hollow profile is welded together from individual blanks.
- a hollow profile with a small cylindrical longitudinal section, a subsequent conical longitudinal section and an adjoining cylindrical longitudinal section with a larger diameter has an overall constant wall thickness, but its production is complex because of the longitudinal sections which can be individually cut, then shaped and then welded together ,
- the weld seams form locations of inhomogeneities, which are necessary for further processing
- Example of high-pressure forming which are disadvantageous and are the starting points for crack formation during further forming and during later operational use.
- the hollow profile is made from a one-piece blank.
- the hollow profile can be widened by internal high pressure forming. If you wanted to produce a hollow profile shape of the example described, the cross-sectional expansion would be at the expense of the wall thickness. Therefore, this manufacturing process is of limited use.
- the invention is based on the issue of developing a less complex manufacturing process for hollow profiles with longitudinally different cross sections from sheet metal blanks, in which there is at most only a small amount of undesirable local thinning of the material and practically none Wrinkling is coming.
- the hollow profile should be as homogeneous as possible over its entire surface in order to be able to be reshaped without damage.
- the blank is deformed in a U-shape in its longitudinally extending central area, shifting from the material to compensate for material deficiency or excess material in each transition area.
- the U-shaped blank is inserted with its closed area into a first die half of a die corresponding to the hollow profile.
- the U-shaped deformation preferably takes place in the first half of the die, in particular using a correspondingly profiled core.
- the invention is based on the idea that in the transition areas, where due to the development of the hollow profile material shortage or
- the blank can be bent inwards on its longitudinal edges before the forming in the die.
- the bending radius of the bent longitudinal edges should at most be equal to the smallest radius of curvature of the hollow profile.
- FIG. 1 shows a blank of a sheet metal blank
- FIG. 2 shows the blank according to FIG. 1 with bent longitudinal edges
- FIG. 3 shows a first forming step of the blank according to FIGS. 1 and 2 in a die with a core in a perspective view
- Figure 4 shows a second forming step of the blank according to Figures 1 and 2 in the die of Figure 3 in a perspective view
- Figure 5 shows the hollow profile after removal from the mold in a perspective view.
- a hollow profile 1 corresponding to FIG. 5 is formed from a one-piece blank of a sheet metal blank, which is composed of three longitudinal sections 2, 3, 4, namely a cylindrical longitudinal section 2 with a small diameter, a conically widening longitudinal section 3 and a cylindrical longitudinal section 4 larger diameters.
- the cutting of the sheet metal blank can be divided into three areas 5, 6, 7.
- the areas 5 and 7 have a substantially rectangular cross section, while the area 6 between them has a substantially trapezoidal cross section.
- a special feature at This blank 5, 6, 7 consists in that the otherwise straight cut edges are rounded in the transition areas 8, 9 between the areas 5, 6, 7, namely the cut edges 8a, 8b are rounded from the smaller rectangular area 5 to the trapezoidal area 6 , while the cut edges 9a, 9b are rounded from the trapezoidal area 6 to the larger rectangular area 7.
- additional material is made available for the transition area 8, while material is removed for the transition area 9.
- a lack of material in the areas 8c, 8d of the transition area 8 and an excess of material in the areas 9c, 9d of the transition area 9, which would result if the hollow profile to be formed were developed in the plane, are compensated for.
- the blank according to FIG. 1 is formed into the hollow profile of FIG. 5 step by step.
- the longitudinal edges ⁇ a, ⁇ b, 7a, 7b, 5a, 5b are preferably first bent inwards, in particular with a bending radius which is at most equal to the smallest radius of curvature of the later hollow profile.
- FIG. 2 shows the blank prepared for the actual forming.
- This blank 5, 6, 7 is then shaped according to FIG. 3 with its central region extending in the longitudinal direction in a first die half 10a of a die 10a, 10b adapted to the later hollow profile with the aid of a core 11, so that a U-shaped molded part with upright Legs 12a, 12b are formed.
- material is shifted in the transition areas 8, 9, so that at most there is only a very small amount of compression and material thickening or thinning in the transition areas.
- the legs 12a, 12b are bent toward one another with a second die half 10b, if appropriate after removal of the core 11, by resting against the second die half 10b until the die 10a, 10b is complete closed is.
- a sword 13 carried by the core 11 serves as a centering for the longitudinal cutting edges.
- this second forming step too, there is a material shift in the transition areas 8, 9, so that material thinning or thickening essentially does not occur.
- the longitudinal cut edges meet and form a linear weldable edge joint.
- the preformed hollow profile produced in this way stands for further forming processes after the longitudinal seam welding, for example
