Definitions

  • the invention relates to a method and an apparatus for producing a hollow profile with a varying over the length of its cross section according to the preambles of claims 1 and 12.
  • hollow profiles with a constant cross-section are not produced in a continuous process. Rather, initially produced seamless or welded welded round or square tubes in the desired length. These are then converted in the hydroforming process into hollow profiles whose cross section does not remain constant, but changes along the longitudinal axis of the hollow profile.
  • the process step of hydroforming is significantly involved in the production costs, since the handling of workpieces that are formed piece by piece, even using industrial robots is quite expensive.
  • the present invention is therefore based on the object to propose a method and an apparatus for producing a hollow profile with a varying over the length of its cross section, with or with the production of such hollow sections faster and more efficient, and thus cheaper.
  • the invention is thus based on the finding that hollow profiles with varying cross-section can also be produced continuously, specifically with a profiling machine comprising a plurality of forming stations with roll forming tools arranged in line one behind the other as well as a welding station.
  • the principle of such a profiling machine is known per se, for example, from DE 198 34 400 C1 of the Applicant.
  • the profiling machine described therein has a plurality of forming stations, in each of which pairwise cooperating roll forming tools are driven for stepwise forming of a metal strip in a continuous forming process or are mounted in freewheeling manner in racks.
  • the metal strip formed into a hollow profile then subsequently passes through a welding station arranged in line, in which the bent-together edges of the metal strip are butt welded together.
  • This known profiling machine is very efficient due to the continuous production process and enables the cost-effective mass production of hollow profiles.
  • Another profiling machine is known per se from US-A-4,558,577.
  • open profiles having a longitudinally varying width are made by roll forming from a metal strip of varying width in the longitudinal direction.
  • This device comprises roll forming tools, the position and inclination of which can be changed during the forming process in order to be able to continuously shape the open profiles of varying width and still remaining sidewall heights.
  • a hollow profile with a cross section varying over its length can be produced on a correspondingly adapted profiling machine with roll forming tools, namely by first including a first metal strip a width varying over its length in the roll forming tools is formed into an open profile, then a second metal strip is placed on the edges bounding the open side of the open profile, and finally the second metal strip with the open profile into a hollow profile is welded.
  • the hollow profile is thus not made of a single metal strip, but of two metal strips, wherein at least the first metal strip according to the desired cross-sectional profile of the finished hollow profile varies in width, that is not provided as usual with parallel edges.
  • the forming of the first metal strip is not completely up to a hollow profile, which in general will not be possible due to its varying width, but by welding a second metal strip to the "gap" of the open profile produced by roll forming.
  • the roll forming and the welding takes place in a continuous process by the method steps according to the invention are carried out in line one behind the other.
  • the first metal strip used does not necessarily have symmetrical edges on both sides; It is for example possible to provide only one side of the metal strip with an edge different from a straight line, so that the desired varying cross-sectional profile can be produced by welding the second metal strip onto this "varying" edge. In most cases, however, it will be useful to mold a more or less U-shaped profile with side walls that vary symmetrically in height, onto which the second metal strip is welded as a cover plate. This results in a hollow profile with the desired cross-sectional profile.
  • the invention makes the efficiency and production speed of a profiling machine with roll forming tools also usable for the production of a hollow profile with varying cross section for the first time.
  • the resulting in particular in a mass production cost advantages are obvious.
  • the welding is preferably carried out with a laser welding system, which allows a pinpoint welding with high local variability of the site of action.
  • the laser radiation is preferably directed substantially perpendicular to the longitudinal axis of the open profile on the contact areas between the open profile and the second metal strip. As a result, the laser radiation with relatively low intensity can nevertheless act on the entire contact area to be welded.
  • the welding device is designed such that its site of action is variable in position; because only then, the welding head or welding heads can be tracked a more or less wavy course of the edges to be welded during continuous transport of the profile through the welding station, thereby eliminating costly mechanisms that would ensure that the weld to be produced always exactly on the appropriate welding head is passed straight ahead.
  • the corresponding configuration of the welding station with a welding device variable in position with regard to its point of action also comprises a scanning device for detecting the current position of at least one of the contact points between the open profile and the second metal strip.
  • This scanning device may in particular be designed electronically, optically or mechanically, wherein it expediently controls the welding device in such a way that its point of action is always directed precisely to the edges to be welded, irrespective of their changing instantaneous position in the welding station during transport of the hollow profile.
  • each weld can be produced a scanning device;
  • a scanning device for example, in the case of U-shaped profiles with upwardly undulating side cheeks which conform to their shape on the right and left, it is also possible to use only one scanning device for both welds to be produced, even if in this case preferably two welding heads, the right and left of the Hollow sections are arranged to be used.
  • a mechanical scanning device for controlling the movement of the welding device It may be provided in particular to use a roller which rolls on the laid on the open profile second metal strip and thereby the current profile of the edge to be welded recognizes and passes on to the welding device.
  • the relative speed between the edges to be welded and the welding device can be detected, this size is preferably used to control the welding performance.
  • the relative velocity between the edge to be welded and the welding device becomes greater when that edge is not straight through the welding station but deviates from the longitudinal axis of the hollow profile so that the welding head or heads are perpendicular to the advancing direction of the profile Have to move.
  • the second metal strip is preferably placed on the open profile by means of a guide roller device, so that it can be placed flush on the more or less wavy course of the edges or edges of the open profile to be welded.
  • a guide roller device can simultaneously serve as a scanning device, with or without control of the welding power.
  • a spring-loaded guide roller device can be provided, which controls the adjustment of an adjustable perpendicular to the longitudinal axis of the profile welding device. This is particularly simple when one or more welding heads of the welding device are mounted directly on the guide roller device. This leads to a particularly simple and compact welding station for hollow sections with varying cross sections.
  • the second metal band can also be provided with punched holes and / or bends before being placed on the open profile.
  • Figure 1 shows a schematic side view of the structure of an embodiment of the device according to the invention: A first, varying in width metal strip 1 and a second, provided in the usual way with parallel longitudinal edges metal strip 2 of a first unwinding reel 3 and a second unwinding reel 4 for continuous production process.
  • the first metal strip 1 passes through a forming system 5 with five frames 6 shown here, in each of which a cooperating pair of driven or free-running roll forming tools 9 effect a stepwise forming of the first metal strip 1 into an open profile 7.
  • the second metal strip 2 is guided past the roll forming tools 9 and transported together with the molded open profile 7 through a welding station 8. There, as described in more detail below, the second metal strip 2 is placed flush on the open side of the profile 7 and welded thereto.
  • the method according to the invention is thus a continuous method with which a cost-effective and rapid mass production of profiles with a varying cross-section is possible.
  • FIG. 2 shows a purely schematic representation of the main functional elements of the welding station 8.
  • the open profile 7, which as a U-shaped profile with a flat, bounded by parallel edges edges base 13 and two side walls 14 is formed, the upper boundary edges 15 have a right and left identical wavy course is continuously guided by a driven, mounted in a frame 16 guide roller 17 through the welding station, the second metal strip 2 is placed flush on the edges 15 and positioned by means of a guide roller device 18 for welding.
  • the guide roller device 18 is not driven and is biased by two springs 19 against the second metal strip 2, so that it provides in cooperation with the guide roller 17 for a clean concern of the second metal strip 2 on the edges 15 of the open profile 7.
  • the contact surface between the profile 7 and the second metal strip 2 is thus defined by the lower surface of the second metal strip 2, so that the instantaneous position of the front rollers 20 of the guide roller device each represent the exact location of the weld to be produced.
  • These rollers 20 also take the current overall speed of the second metal strip 2 and thus the edge 15 of the profile 7, which is composed of the feed rate of the profile 7 and the perpendicular to the longitudinal axis of the profile 7 extending movement of the guide roller device 18.
  • the rotational speed of the rollers 20 is used to control the welding power.
  • a first and a second welding head 21, 22 are fixed to the axis of the rollers 20, which each focus a laser beam on the contact area between the edge 15 of the profile 7 and the metal strip 2.
  • the arrangement of the welding heads 21, 22, the guide roller device 18 automatically transmits the varying contour of the profile 7 on the welding heads 21, 22, so that they are tracked very exactly the edge 15 of the profile 7.
  • the hollow profile 11 with varying cross section leaving the welding station 8 shown in FIG. 2 can be seen again in FIG. It is a part of the hollow section 11 which is cut to length by the cutting machine 10 and consists of a U-profile 7 with wave-shaped side cheeks 14 and a shroud 23 which is laid onto the side cheeks and welded thereto.
  • the geometry shown in Figure 3 can be made quite easily by the first metal strip either already has a prefabricated, varying width, or stamped in a arranged in line to the coil pre-punching one of the different end heights of the U-profile 7 corresponding contour of the tape longitudinal edges gets.
  • the forming 5 ensures the deformation of the first metal strip 1 to the U-profile 7, wherein the lateral band guide can be ensured by means of sprung mounted side rollers.
  • the continuously supplied during the process shroud 23 in the form of a second metal strip 2 is welded in the welding station 8 on the undulating edges 15 of the side walls 14, wherein the welding power was chosen lower on the purely horizontal sections of the hollow section shown here, as to the Ramp-shaped sections, which naturally have a higher relative speed to the welding device in the continuous flow process, as the horizontal sections.
