Definitions

  • the invention relates to a method for shaping bodies by structuring reshaping of their evenly formed surface contour, under Application of partial forces on the body, in which the force is applied a selected sectoral area of the body is directed (see e.g. FR-A-2 152 349).
  • deforming force Strength solid support cores corresponding to the structure to be trained are used have to. These support cores act like a matrix and allow the structure Form contactless according to the requirements of the intended use. It can also be gathered from DE 44 47 268 A1 to fold heat transfer tubes and provided with concave sections. The method disclosed gives in his Process representation no clue as to whether the deformation using Support cores or thermal aids are used.
  • the DE 44 01 974 A1 discloses a method and a device for buckling deformation. According to the The procedure is a dent structuring by the partial input of forces on the material to be deformed, however, the process is not without its use of support cores possible.
  • DE 44 37 986 A1 further discloses a method to apply curved material webs and foils with positive and negative pressure and thereby achieving a buckling structure.
  • a supporting grid necessary on which the material web rests. Determine the openings of the support grid size, contour and intensity of the structuring to be applied.
  • the invention has for its object a method for shaping bodies by structuring remodeling of their evenly formed surface contour, using forces partially directed at the body, by means of which the Production of surface structures of bodies through changing deformation intensities can be carried out.
  • the invention solves the problem by means of a method for shaping bodies through a structuring remodeling of their evenly formed surface contour and application of forces directed partially at the body in which the force is applied directed to a selected sectoral area of the body, in its size as well as sectoral extension as far as it is held and as long as that it is necessary to complete the partial shape in the intended contour, whereby after a withdrawal of the deforming force, the restoring force in the contour of the deformed body is permanently absorbed that the sectoral areas themselves repetitively, to be arranged on the bodies when shaping in a selected grid alternately concave indented and convex structures which form turned apex regions are formed, the deformation forces entered by the surface structure generated formed static forces are absorbed.
  • the invention is useful if the force acting briefly and impulsive and limited in its depth, to the body to act is brought, with a permanent form compliance by the action of deforming force is achieved in the range of an elastic deformation, which in the partial deformation areas of the concave and convex Structures are transferred into the plastic area.
  • the invention is thus advantageously designed for rotationally symmetrical bodies the acting forces are directed radially, equiangularly and concentrically, the Providing the body with structuring deformations, brought into engagement the sectorial deformation on the surface of the body, this in both Body axes are structured evenly, running.
  • a sensible one Formation of the idea of the invention can be seen in the fact that the forces be dynamically entered into the body and the body in one against the Outer contour directed working impact, lasting and stable, with a Express freely definable structure.
  • the method according to the invention has the advantage on the fact that structuring by means of dynamically and briefly acting forces primarily a dent structure, in particular on thin-walled hollow bodies or flat monolithic body or material can be made.
  • the effect of the forces that act without contact is their depth of action in the material limited inside.
  • the material is advantageously made by means of a dynamic Crane impact, which is vectorially limited and directional, without the aid of support Cores or matrices or other form documents in the material of the body brought in.
  • the peculiarity of the method allows the dimensional stability of the To achieve structure in that the structured surfaces in their sole and Vertex areas, i.e. where the greatest deformation is to be seen, in partial Material areas are plastically, i.e. permanently deformed, and that of a smaller one Deformation work exposed areas of the structure to be elastically deformed then support elastically against the crown and sole areas.
  • This will help Application of the process by the realized in a plastic deformation Deflection of the material in the sole and crown areas gives the opportunity that the partial parts of the structure exposed to less deformation work themselves support elastically against the sole and apex areas of the structure.
  • the effect of the method is advantageous in that not only the structure by a registered deformation work is generated par excellence, but that this deformation work is partially different in the treated workpiece and plastic as well elastically deforming areas are generated after the completion of the deformation work maintain their position obtained from the deformation. So it is according to the invention also allows the process to be shaped in such a way that those attacking for structuring Forces with the use of mechanical means on the areas to be structured Body to be brought into effect.
  • the shape of the structure entered in the body is one over both body axes extending regular and interrupted training, being after a Form of embodiment of the invention the shape of the structure entered in the body, a regular and interrupted training that extends over the body axes having.
  • FIG. 2 shows an embodiment of the method.
  • this procedure is a horizontally arranged tube 11 of any length, a nozzle ring 13, the tube 11 comprehensive in a concentric position.
  • the nozzle ring 13 is in its on the Pipe surface facing interior provided with nozzles that create a profiling jet 15 aim at the surface of the tube 11.
  • the Nozzle ring 13 For profiling annular dent structures with on the circumference of the tube 11 evenly distributed dents 12, it is necessary that the Nozzle ring 13 a number of profiling beams corresponding to the number of bulges of the bulge ring 15 has.
  • the profiling jets 15 of the nozzle ring 13 occur evenly divided distances from the inner surfaces of the nozzle ring 13 and are on the Surface of the tube 11 directed.
  • the working direction of the profiling beams 15 is adjusted to the longitudinal center axis of the tube 11 and allows an evenly distributed partial structuring effect on the pipe 11.
  • the work intensity of the profiling beams 15 is designed so that its exposure time is very short and with high pressure, abruptly deforming, acts on the surface of the tube 11.
  • the partial effect the profiling beams 15 are concentrated at certain points on the sole regions 29 the dent structure.
  • the support beams 16 are at the same distance from the action point 30 the profiling beams 15 arranged and meet in the apex areas of the longitudinal extent the dents 12, which take effect in the interior. Since the support beams 16 the Action pressure of the profiling beams 15 should partially restrict and only in must be profiling in certain cases is their pressure and theirs Working pulse of the intensity and the pulse shape of the profiling beam 15 adapted. This means that the support beams 16 simultaneously, the working effect of the profiling beam 15th supportive, effective, but no greater in pressure than that Pressure of the profiling beams 15.
  • the course of the method is considered on the safe procedural regime of the fundamentally dynamic and short-term one Deformation force in the direction of the tube 11 and considering the formation self-holding buckling structures are made even safer in their effect, that support jets 16 the location and shape of the bulges 12 or bulge structures to be formed design dimensionally secure in their width and position of the vertices 29 to let.
  • the process achieves its safe implementation when the support beams 16 stagger the later apex areas of the outer contours of the Hold buckling rings and for the action of the dynamically impacting profiling beam 15 secure to action point 30 of dents 12.
  • the range of variation of the The method also finds expression in the fact that the counterforce of the support jets 16 at the same time and impulsively in response to the sudden pressure of deformation of the profiling beam 15 are used and thus the structural profile 16 help to make it homogeneous
