Definitions

  • the invention relates to a method for producing a tool, for forming workpieces, wherein the tool comprises at least a first mold half and a second mold half and each mold half has at least one active surface, which faces the other mold half, so that with the active surfaces of the tool Workpiece is deformable.
  • Forming tools in the context of the invention are, in particular, pressing tools, cutting tools, thermoforming tools or postforming tools, which are used for processing sheet metal blanks.
  • Such tools are for example from the DE 10 2004 054 679 B4 known.
  • reaction forces occur on the forming forces which lead to elastic deformation of the tool and of the press.
  • the deformation of the entire system press and tool takes place in all components involved in the load flow, in particular the press table, the press ram, the tie rod, the gear and the tool.
  • the ram stroke is adjusted in the prior art.
  • the active surfaces of the tools are reworked.
  • the invention proposes a method for producing a tool for forming workpieces according to claim 1.
  • the method may include the steps of producing the active surface of the first mold half and producing the effective surface of the second mold half, wherein at least in the generation of the active surface of the second mold half, the elastic deformability at least one tool half is taken into account.
  • Such forming tools are in particular deep-drawing tools, pressing tools or similar tools in which, for the purpose of forming a workpiece, it is at least partially clamped between the active surfaces of the tool halves.
  • the elastic deformability of at least one mold half can be taken into account when producing the effective surface of the first mold half.
  • the elastic deformability of both mold halves is taken into account.
  • the elastic deformability of a pressing device in which the tool is mounted is taken into account when producing the effective surface of the first and / or the second mold half.
  • this increases the accuracy in the production of the final contour of the active surface, so that the effort in the rework is further reduced.
  • the following steps can be carried out, producing a provisional effective surface of a mold half, determining the elastic bending or elastic deformation of at least one mold half by means of a finite element simulation, generating a displacement field, in which punctual displacements of the effective surface over the course of the provisional effective surface of the tool halves are determined, based on the simulation results, determination of a deformation function from the displacement field and application of the deformation function to the provisional effective surface of at least one of Tool halves for producing the effective surface of the tool half.
  • the provisional active surface is a first active surface of a tool half, which largely corresponds to the negative shape of the active surface of the corresponding tool half when the press is closed and without the action of process forces.
  • the effective surface generated taking into account the displacement field represents a final effective surface of the tool half, which in the unloaded state does not correspond to the negative shape of the effective surface of the corresponding mold half. Only by applying the forming forces, the active surface of this mold half is deformed so that it corresponds to the negative mold of the corresponding mold half.
  • the elastic deformation or the elastic deflection of the press can be taken into account in the production of the active surface, wherein the elastic deformation of the press is also taken into account in the finite element simulation.
  • the elastic deformation of the press is also taken into account in the finite element simulation.
  • the determined deformation function can also be applied to a blank holder for determining an effective surface of the blank holder.
  • the blank holder acts together with a surface on the second mold half, wherein on this surface also the deformation function is applied.
  • the acting process loads can be determined from the results of a forming simulation and used in the form of many individual forces in the finite element simulation.
  • FIG. 1 the basic structure of a forming device described here a press 10.
  • the forming device 10 comprises a table 15 which is supported on a base 19 via support elements 18.
  • the drive 11 is connected to a plunger 12.
  • the forming tool comprises a first mold half 14 and a second mold half 13, which form a cavity in a closed position of the tool.
  • the first tool half 14 is fixed to the table 15 and the second tool half 13 is fixed to the plunger 12.
  • the plunger 12 and thus also the second tool half 13 can perform relative movements to the first tool half 14.
  • FIG. 1 Consequently, lifting and lowering movements of the second tool half 13 can be generated in order to run through a working cycle of the press 10 or of the tool.
  • the cavity of the tool is open.
  • the two tool halves 13, 14 form the cavity.
  • a cycle of the press comprises a movement of the second tool half 13 from top dead center to bottom dead center and back to top dead center.
  • the parting line of the tool halves 13, 14 extends substantially in the horizontal direction, wherein the working direction of the press in the figures corresponds to a vertical working direction.
  • a workpiece 20 for example, a sheet or a sheet metal blank is introduced and formed by moving together the tool halves 13 and 14.
  • the first tool half 14 is in the FIGS. 1 . 3 and 4 formed as a lower mold half and includes a punch and a sheet holder 16.
  • This sheet holder 16 is for fixing the workpiece 20 in a predetermined position provided, and is also in the direction of the press, ie in FIG. 1 movable in the vertical direction.
  • FIGS. 3 and 4 In the FIGS. 3 and 4 is pressed by an upward movement of the sheet holder 16, the sheet to be machined 20 against the second mold half 13 and thus fixed in place.
  • the second tool half 13 moves downward, and the blank holder 16 is displaced downward.
  • the second tool half 13 is as an upper tool in the FIGS. 1 . 3 and 4 represented and formed as a template.
  • This die has an area in which it cooperates with the punch and one or more areas in which it interacts with the sheet metal holders 16.
  • the workpiece 20, here a sheet metal blank is pressed against the blank holder 16 in the areas of the die, which cooperate with the blank holder.
  • the sheet metal blank 20 is clamped so that a defined post-tiling of the sheet material is made possible.
  • the bottom 19 and the ceiling 21 are right and left side in FIG. 1 connected by tie rods 17 to avoid that due to reaction forces generated by the deformation, the ceiling 21 and the bottom 19 move away from each other.
  • FIG. 1 a two-part tool is shown, with a stationary lower tool 14 as a first tool half and a translationally movable second tool half 13 as an upper tool.
  • both tool halves 13, 14 can perform relative translational movements to each other to reshape the workpiece 20.
  • press 10 with the tool halves 13, 14 has the disadvantage that the tool does not close over the entire effective area, or is applied to the workpiece when it is in a closed position. This creates a non-constant Pressure distribution, which is why the component surfaces are not satisfactorily pronounced. Consequently, the tool and thus the tool halves 13 and 14 must be fooled.
  • FIG. 1 Since this is done initially on a single-use press, which is not identical to the later production press, the tools must be faked multiple times.
  • the press 10 in FIG. 1 is shown in an open position after a sheet 20 has been reshaped. In reality, no process forces act on the sheet 20 in this position, so that the table 15 and the plunger 12 are not bent. However, to better explain the problem with which the invention is concerned, is in FIG. 1 in this respect deviated from the reality by table 15 and plunger 12 are shown bent.
  • FIG. 2a is a known from the prior art tool half 13 with an active surface 13 a shown.
  • the contour or the course of the effective surface 13a corresponds to the contour or the course of the outer geometric shape of a component to be produced.
  • shown tool half 13 provides only on the assumption that forming forces do not cause elastic deformations in the mold half 13, a sufficiently pronounced desired geometry.
  • the in FIG. 2a shown tool half 13 and the contour of the effective surface 13a is a starting point in the generation of the final effective surface.
  • the elastic deformation or the deflection of this provisional effective surface 13a is determined in a finite element simulation.
  • finite element simulation the forming force with which the tool halves act on the workpiece is used as a load. Nodes are defined here and the discretely acting process loads in the Determined points.
  • the acting process loads are determined from the results of a forming simulation and enter into the finite element simulation in the form of many individual forces. When determining the prevailing during forming process forces or process loads and the material of the workpiece, as well as its thickness is taken into account.
  • the resulting from the finite element simulation course of the bent, provisional effective area 13a is in FIG. 2b shown with the dashed line.
  • a displacement field is determined, in which the punctual displacement or deflection over the course of the provisional effective surface 13a is determined.
  • a deflection is determined by which the provisional effective area 13a shifts to the deflected effective surface 13b.
  • the finite element simulation takes into account the process forces acting on the sheet metal blank. Since the determination of the process forces, in addition to other sizes, also takes into account the sheet thickness and the sheet material, these parameters are incorporated into the finite element simulation.
  • FIGS. 3 and 4 Two alternative embodiments of the invention are shown in FIGS. 3 and 4 represented, wherein the same reference numerals the same components, as already to the FIG. 1 described press device, denote.
  • the tool is shown in an open position, wherein the tool halves are not positive fit to each other and both table 15 and plunger 12 are bent.
  • This serves only as a graphical representation for explaining the invention.
  • the tool halves 13, 14 fit together (tool is closed). If the active surface contours remain in the position shown (tool open), extend table 15 and plunger 12 in parallel or without deflection. Ie in the FIGS. 3 and 4
  • the shape of the tools 13,14 corresponds to an unloaded state and the shape of the table 15 and the plunger 12 a loaded state.
  • the second tool half 13 has a profile of the effective surface, which is based on the course of the active surface of the second tool half 13 FIG. 1 different.
  • the curves or the contours of the second tool halves 13 are convexly curved according to the invention. So if a workpiece 20, for example, a metal sheet with the tool according to the invention according to the FIGS. 3 and 4 is transformed, the plunger 12 is moved thereon with the second tool half 13 in a working direction, which corresponds to a direction of movement downwards in the FIGS.
  • the first tool half 14 and the second tool half 13 come together and shape the workpiece 20.
  • the elastic deformation generates a deflection of at least the second tool half 13, so that the active surface of this second tool half 13 has the same course as the provisional operative surface 13 a as in FIGS FIGS. 2a to c shown. This gives the component to be manufactured its final outer shape.
  • the blank holder 16 are also formed curved.
  • the deformation function which is determined from the finite element simulation, is also applied to the blank holder 16 according to this embodiment.
  • the tool halves can also be designed as a so-called multiple cavities. This makes it possible with a pair of tool halves comprising an upper tool and a lower tool to produce several components during a work cycle.
