Definitions

  • the invention relates to a longitudinal profile, the type mentioned in claim 1, and a method for producing such a longitudinal profile.
  • a strip-shaped rolling stock longitudinal profiles with mutually aligned at an angle side walls are known in various embodiments.
  • this has two side walls to form an L-shaped open longitudinal profile.
  • U-shaped or C-shaped longitudinal profile which is open along its longitudinal extent this has three side walls, wherein two side walls are arranged running parallel to one another on the third side wall.
  • material-intensive open longitudinal profiles as they represent, for example, C-shaped mounting rails, the proportion of material costs compared to the total cost of more than 70%.
  • savings in material lead to a significant reduction in manufacturing costs.
  • a longitudinal profile does not necessarily have to have a constant thickness or material thickness over its circumference.
  • the thickness can be partially reduced and thus material can be saved. If the thickness-reduced regions are positioned on the rolling stock in accordance with the later design of the longitudinal profile formed from a strip-shaped rolling stock, the load absorption and the resistance moment of the longitudinal profile, for example if this is designed to be open along its longitudinal extent, are only insignificantly influenced.
  • a disadvantage of the known solution is that in a longitudinal profile along its longitudinal profile at a load with high single loads or due to external influences, eg. As during transport or during assembly of the profile, undesirable deformations in the portions of the reduced thickness portions of the longitudinal profile, in particular if this is designed to be open along its longitudinal extent, may occur.
  • the object of the invention is to provide a longitudinal profile that is versatile in spite of thickness-reduced areas.
  • Another object of the invention is to provide a method for producing a longitudinal profile, wherein the method can be easily integrated into a manufacturing process of the longitudinal profile.
  • the at least one thickness-reduced region is provided with a profiling.
  • this region is stiffened without an additional use of material and the strength of the side wall provided with at least one longitudinally extending, reduced-thickness region approximates the strength of a side wall which has a constant material thickness over its entire width.
  • the at least one thickness-reduced region is arranged on mutually opposite side walls of a C-shaped longitudinal profile.
  • a C-shaped longitudinal profile such as a C-shaped mounting rail, represents a material-intensive profile, so that the manufacturing costs for such an open longitudinal profile can be significantly reduced by means of a region-wise reduction in thickness and consequent material savings.
  • the thickness of the bottom section between openings arranged in the latter and also the thickness of the side walls can be partially reduced.
  • the strength of such a C-shaped longitudinal profile can be approximated to the strength of a C-shaped mounting rail which has no thickness-reduced areas and therefore a greater material requirement.
  • the profiling is aligned transversely to the longitudinal extension of the at least one thickness-reduced region, wherein a sufficient stiffening of the corresponding side wall of the longitudinal profile is ensured.
  • the profiling is oriented obliquely to the longitudinal extent of the at least one thickness-reduced region, whereby any internal stresses occurring during the formation of the profiling can advantageously be reduced within the strip-shaped rolling stock.
  • the profiling is arranged with an offset to at least one side of the side wall, so that at least on one side of the side wall of the longitudinal profile no section of the profiling projects beyond this side and thereby limits a trapped by the aligned side walls receiving space of an open longitudinal profile along its longitudinal profile.
  • the profiling may protrude over one of the sides of the side wall, for example.
  • the profiling can be designed such that it is spaced apart on both opposite sides of the side wall with an equal or different large offset.
  • the profiling at least partially project beyond both of the opposite sides of the side wall.
  • the profiling is formed by alternately arranged depressions and elevations, which are easy to produce and ensure an advantageous stiffening of the thickness-reduced areas of the side walls.
  • the depressions and elevations are trapezoidal in cross section.
  • the recesses and elevations are formed on both sides with respect to a median plane of the side wall, which allows a uniform configuration of the side wall and ensures the reduction of any occurring internal stresses in the deformed, reduced thickness region of the side wall.
  • the recesses and elevations have boundary edges which are arranged obliquely to the longitudinal extent of the side wall, whereby any internal stresses occurring during the formation of the depressions and elevations can advantageously be reduced within the thickness-reduced region of the side wall.
  • the recesses and elevations have in plan view, for example, a parallelogram or trapezoidal configuration, wherein the adjacent sides of juxtaposed depressions and elevations advantageously parallel to each other.
  • a longitudinal profile in particular a longitudinal profile which is open along its longitudinal extent, with side walls aligned in the longitudinal direction, wherein at least one side wall has at least one thickness-reduced region along its longitudinal extent, it is transverse to the longitudinal extent of the side wall by means of at least two profiled rollers arranged opposite one another formed a profiling in the at least one thickness-reduced area.
  • a strip-shaped rolling stock is advantageously used, which can then be formed into a plurality of longitudinal profile shapes.
  • the profile rollers preferably have embossed regions with raised sections and recessed sections which mesh with one another to form the profiling in the at least one thickness-reduced region.
  • the thickness-reduced region of the side wall lying between the embossing regions of the profile rolls is deformed relative to one another, wherein the region of the side wall not reduced in thickness is fixed by smooth regions next to the embossing regions of the profiled roll.
  • the formation of the profiling in a side wall of the longitudinal profile which is aligned obliquely to a rotational axis of the profile rollers, for which the at least two oppositely arranged profile rollers have at least one obliquely arranged to the axis of rotation of the rollers embossing area.
  • the oppositely arranged embossing areas of the profile rollers are aligned parallel to each other. Due to the oblique to the axis of rotation of the profile rollers arranged embossing regions, these profile rollers along these embossing regions on different peripheral speeds, which causes a so-called longitudinal slip when forming the profiling. This longitudinal slip counteracts the frictional resistance of the profiled roller transversely to the direction of travel of the side wall, wherein the sidewall in the thickness-reduced region is easily stretchable when forming the profiling.
  • the profile rollers have, in accordance with the number of the plurality of thickness-reduced regions, a plurality of embossed regions, for example with raised sections and recessed sections. Between and next to the embossing areas, the profile rollers for fixing and any subsequent rolling of the side walls on smooth rolling areas.
  • the free ends of a side wall are formed before the formation of the profiling, which leads to a reduction in the rigidity of these end portions not reduced in thickness. Due to the reduced rigidity, even with a side wall with a small thickness, distortions of the free end regions during the formation of the profiling are prevented.
  • the open longitudinal profile 11 shown in Figures 1 to 3 is designed as a C-shaped mounting rail, the parallel side walls 12 and a has the two side walls 12 connecting bottom portion 13.
  • the side walls 12 each have, along their longitudinal extent L, a thickness-reduced region 14 which is provided with a profiling 15 oriented transversely to the longitudinal extension L of the thickness-reduced regions 14.
  • the profiling 15 is formed by alternately arranged recesses 16 and elevations 17.
  • the depressions 16 and elevations 17 have a trapezoidal configuration in cross-section (FIG. 3) and are formed alternately with respect to a center plane 18 of the side wall 12 running in the longitudinal extension L.
  • the recesses 16 and the elevations 17 have a rectangular configuration.
  • a side wall 22 which is shown in partial detail in FIG. 4, has depressions 26 and elevations 27 in its thickness-reduced region as profiling 25.
  • the elevations 27 are arranged to one side 28 of the side wall 22 with a protruding offset V.
  • side wall 32 of an open longitudinal profile 31 has profiled 35 in its reduced thickness region 34 recesses 36 and elevations 37, which have a parallelogram-like configuration and boundary edges 36 and 37 in plan, arranged obliquely to the longitudinal extent L of the side wall 32 are.
  • process step two in the longitudinal direction L or in the rolling direction of the side walls 12 extending thickness-reduced regions 14 formed on a strip-shaped rolling stock.
  • the thickness-reduced regions 14 each have a reduced thickness E which is smaller than the thickness D of the strip-shaped rolling stock in the adjacent regions.
  • profile rollers 51 and 56 transversely to the longitudinal extent L of the side walls 12 extending recesses 16 and elevations 17 are formed as profiling 15 in the thickness-reduced areas 14 of the side walls 12.
  • the profile rollers 51 and 56 have embossed regions 52 and 57 with raised portions 53 and 58 and recessed portions 54 and 59, respectively, which engage in one another to form the profiling 15 in the thickness-reduced regions 14. Between and beside the Stamping areas 52 of the profile roller 51, this has a smooth surface 55.
  • the profiled roller 56 also has a smooth surface 60 between and next to its embossing areas 57.
  • the free ends of the side walls 12 have been reshaped so that the edge region 19, which is not reduced in thickness D, has a lower rigidity than an edge region with an unformed end.
  • the strip-shaped rolling stock is formed into a C-shaped mounting rail.
  • FIG. 8 shows a part 70 of a rolling device for carrying out a further method for producing an open longitudinal profile.
  • profilings 85 in a reduced-thickness region 82 takes place in a section of a side wall 81 which has previously been oriented obliquely to a rotation axis 78 or 79 of two profile rollers 71 and 76 arranged opposite one another.
  • the profiled roller 71 has two embossed areas 72 arranged at an angle A to the axis of rotation 78 of the profiled roller 71.
  • the profiled roller 76 has two embossed areas 72 arranged at an angle B to the axis of rotation 79 of the profiled roller 76.
  • the oppositely arranged embossing regions 72 and 77 are aligned parallel to each other.
  • the embossing areas 72 and 77 of the profile rollers 71 and 76 each have raised portions 73 and 78 and recessed portions 74 and 79, respectively, which engage in one another to form the profiles 85 in a thickness-reduced areas 82.
