Definitions
- the invention relates to a molded part according to the preamble of claim 1 and a method for producing a molded part according to the preamble of claim 12.
- Such moldings are for example machine parts with contours for transmitting force and movement such as cams, ramps with gradients in the axial direction and in the circumferential direction, switching scenes in the form of openings, switching scenes in the form of depressions, meandering structures and gears. If high strength and accuracy requirements apply to such molded parts, their production is very complicated and expensive. For example, in racks, especially for steering systems of motor vehicles, it is important to obtain the most accurate tooth geometry and high tooth strength. In the prior art, there are a number of methods by which racks are produced by forming or machining processes and corresponding post-processing steps. But such racks often have a high weight and correspondingly high material costs.
- JP 11-180318 A a method for producing a hollow rack made of a flat sheet is presented, in which in a first step, the sheet is bent into a U-shape, wherein the connecting portion between the two U-legs is semicircular. Subsequently, the toothing is pressed into the apex of the arc of the connecting portion and bent the legs to a closed tube profile.
- the toothing is first pressed into the flat sheet metal. Subsequently, the areas of the sheet are bent next to the teeth to a closed tube.
- the legs of the U-profile are unequal in length and it is the longer of the two legs transformed to form the closed pipe profile.
- the tooth shape is not very accurate to produce. The bending operations bring tension in the area of the teeth, which leads to a distortion of the teeth. This also changes the uneven leg length only a little.
- Sheet metal is assumed to be a (piecewise) plane strain state for simplicity, resulting in essentially two main strain directions, one inside the sheet metal piece In the case of bending, the shape of the piece of sheet metal is plastically deformed along these major changes in shape ptform selectedungs line be designated.
- a bending line of the molding is defined as extending from a point of the molding along a maximum of the bend of the molding. In the case of bending deformation of the molding, it corresponds to the neutral fiber in cross-section at right angles to the axis about which the molding is bent.
- the object of the invention is to provide a formed from a flat piece of sheet metal by forming the flat piece of sheet metal molded part of the type mentioned, which has a very precise form of the at least one element element at a low production cost.
- a method for producing a molded part of the aforementioned type is to be provided in which a very high precision of the element is already achieved after the forming.
- Core idea of the invention is that can be influenced by appropriately introduced into the sheet weakening and / or holding edges introduced by the subsequent forming steps in the sheet tension distribution.
- stresses in particular bending stresses over transversely to a main strain curve line, such as a bending line, extending weakenings, such as beads or milled grooves, transmitted only to a small extent.
- weakenings such as beads or milled grooves
- the main strain-change line is selected along which the strain would be transmitted during the subsequent forming steps into the portion in which the forming element is disposed.
- the partial region having the shaped element thus represents a region which is as uninfluenced as possible by the influence of subsequent transformations. At least the partial region corresponds in its extent to the expansion of the formula element.
- the shaped element can be, for example, a surface contour introduced into the wall of the molded part within the partial area or a non-continuous or continuous recess introduced into the wall of the molded part in the partial area or can be formed by a plurality of such recesses.
- a main deformation line for example a bending line, seen in front of and behind the partial area or the shaped element, ie in cross section parallel to the main strain line, for example a bending line, seen on both sides of the partial area or of the formula element in each case at least one weakening and / or holding edge.
- a weakening or holding edge could be provided on each side of the subregion.
- the subsequently planned forming operations are advantageously taken into account.
- numerical simulations FEM simulations
- the weakening points are to be designed in such a way that the stresses introduced outside the subregion, in particular bending stresses, can be dissipated at the weakened point. This means that as a rule the weakened areas partially or completely delimit a partial area to be protected.
- the material flow is greatly reduced by the installation of the corresponding shoulders or edges on the tool.
- the weakenings in this case also form holding edges at the same time. This further reduces an introduction of stresses into the subarea that is delimited by the weakenings.
- at least one retaining edge is designed as a weakening.
- retaining edges which do not simultaneously represent weakening. Weakening may be advantageous over retaining edges, inter alia, in that contact with the tool at the point of weakening during forming is not required to avoid unwanted deformations in the portion having the feature. In the case of a retaining edge, a tool contact is required.
- a molded part according to the invention may, for example, be a machine part with a molding element arranged in at least one partial area for the purpose of transmitting force and / or movement, wherein the molding element may be, for.
- a cam ramp with slope in the axial direction and / or in the circumferential direction
- a shift gate in the form of a non-continuous or continuous recess (ie in the form of a depression or breakthrough), a meandering structure or a toothing can be.
- the mold element is a surface structure with an optical effect, such. B. in a Fresnel lens.
- Molded part is at least one further deformation of the molded part, which represents or includes in particular a bend of the molded part carried out, wherein the respective introduced weakening and / or holding edge counteracts a further uncontrolled deformation of the molded part in the partial area.
- the partial region in which the molded element is located is preferably on both sides of at least one weakening and / or retaining edge, with reference to the main deformation line, for example a bending line, formed during the deformation, in particular bending operation, which takes place to form the molded part demarcated, this weakening or holding edge transverse, preferably orthogonal, to the main strain line, such as a bending line runs.
- At least one preliminary forming of the piece of sheet metal which in particular constitutes or comprises a bending of the molding, has already been carried out.
- the weakenings and / or holding edges are preferably formed linear.
- the linear course can be straight. Also, a curvatures and / or angularly extending sections having line-shaped course is conceivable and possible. Furthermore, interruptions of the weakenings and / or holding edges in the linear course are possible.

- the subregion 5 in the longitudinal direction 2 is additionally delimited by the holding edges 37, and arches 38, which also serve as holding edges.
- the delimitation by the weakening points and / or holding edges does not have to take place without interruption. It is readily conceivable and possible to provide gaps in the portions of the weakenings and / or retaining edges.
- the delimitation of the portion 5, in which the toothing 6 is introduced increases the quality in the longitudinal direction, but is not necessarily required because of the direction of the toothing and the forming steps necessary in the manufacturing process, since only a small proportion of stresses in the sub-range 5 is introduced from outside.
- the weakenings 7 - 12 which delimit the partial region 5 with respect to the circumferential direction 4, are provided in order to transmit the stresses in the Part 5 to reduce. It is preferable in this case if the length 25 of the weakenings 7 - 12 corresponds at least to the length of the partial region 5, that is to say at least the length of the toothing 6, measured in the longitudinal direction 2.

- the depth 33 is then preferably at least 1/6 of the wall thickness of the wall 3.
- embossing depths that are greater than half the wall thickness, should be avoided.
- the use of iHaltekanten is also conceivable and possible on these longitudinal sides of the portion 5, wherein it should be noted that the embossed grooves shown in the example already act in addition to the effect of weakening as a holding edge when the grooves in the subsequent forming in contact with the Stand tool.
- the distance 24, 24 'of the center lines of the weakenings and / or holding edges 7, 8, 9, 10, 11, 12 from the outlet 32 of the toothing 6 in the circumferential direction 4 amounts to at least 1/3 of the wall thickness of the wall 3 in the preferred part.

- the distance 24 'from the tooth outlet 32 to the second weakening and / or holding edge in the circumferential direction 4 is located in the preferred case approximately in the range of 2/3 of the amount of wall thickness of the wall 3 to twice the wall thickness of the wall 3. If in addition to a further weakening 11, 12 on the inner surface 14 of the wall 3 are provided on both sides of the toothing, it is preferably arranged in the circumferential direction 4 between the two externally arranged weakenings and / or holding edges 7, 8, 9, 10.
- the number of weakening points and / or holding edges and their location on the inner surface 14 or outer surface 15, the wall 3 set.
- An arrangement of retaining edges is preferred only on the outer surface 15 of the wall 3, since it is simply possible only during the first forming stages, a tool contact between the retaining edge and
- Weakening and / or Haitekanten that delimit the portion 5 in the circumferential direction 4 could also extend at an angle to the longitudinal direction 39, preferably at an angle of less than 45 ° to the longitudinal direction 39th
- the flat sheet metal in a forming tool consisting of punch 17 and die 18, in a half-shell-shaped or U-shaped form, comprising two legs 19, 20 with two ends 21, 22 and a connecting portion 23 which is arranged between the two legs 19, 20, reshaped.
- the two legs 19, 20 are not parallel to each other, but in the direction away from the connecting portion 23 is openably aligned.
- the end pieces of the two legs 19, 20 are slightly bent after the forming, such that the planes on which the two leg ends 20, 21 are located within of the connecting portion 23 and of the Cut legs 19, 20 partially enclosed space. It is irrelevant whether the bending of the two leg ends 20, 21 in a previous forming step or integrated in this first step, as illustrated in Fig. 3, has taken place.
- the workpiece is illustrated after the first forming step in an isometric view. The partial region 5 in which the toothing 6 is introduced in the later forming steps is indicated by the dashed lines.

- the open non-parallel alignment of the two legs 19, 20 facilitates retraction of the punch 26 to the inner surface 14, which on the one hand facilitates the formation of the toothing and on the other hand, the indentation of the weakenings 11, 12 on the inner surface 14 of Wall 3 allows.
- the stamp 26 can be moved out of the workpiece after deformation without damaging the inner surface 14 and the leg ends 21, 22.

- An example of this is the inner contour in the region of the toothing 6, as shown in FIG.
- mold elements corresponding to the stamp 26, such as edges can be provided. At least one of these form elements, preferably all, is arranged in the circumferential direction at a distance from the toothing, so it is not below the same.
- the formed workpiece corresponding to the same intermediate stage of the forming sequence, as illustrated in FIG. 4, is illustrated in an isometric view.
- first the toothing and then the weakening can be introduced into the workpiece. It is also conceivable and possible to introduce some of the weakenings in a first step and then to introduce the toothing and subsequently the remaining weakenings into the workpiece. Alternatively, fewer weakenings can be introduced into the workpiece.
- the weakenings can also be made in other ways than pressing. For example, the weakenings may be introduced by a rolling or rolling process.
- the two legs 19, 20 are closed further.

- deformation takes place a facilitated bending along the fold lines 34, which are formed by the weakenings I 1 8, 9, 10, 11, 12 in the wall 3 of the workpiece.
- the Forming stresses that lead to the deformation of the two legs can cause a plastic deformation in this way only to a very small extent or not at all in the area of the toothing 6.
- Small remnants of the forming stresses are supported by the friction in the forming tool 29, which carries the negative contour of the toothing. As a result, a further deformation of the toothing can be largely avoided.
- FIG. 6 illustrates the last forming step in which the two legs 19, 20 are formed into the final shape of the rack 1.
- the formation of the teeth and the generation of the weakenings or holding edges can be done in this embodiment together in a single forming step in a forming tool.

- the weakenings are formed as embossed grooves in the examples illustrated in the figures. It is alternatively conceivable and possible to interpret the weakenings as corrugations which may be rolled or pressed. Likewise, the weakenings and / or holding edges can be produced by a machining process, for example milling. However, it is also conceivable and possible to interpret the weakenings as breakthroughs. Further, areas of the workpiece may also be annealed to achieve such weakening.
- the weakenings and / or holding edges are already introduced into the starting workpiece, the flat plate 16. This can be done in a simple manner by a stamping operation simultaneously with the cutting of the sheet metal pieces 16 of a coil. It is even conceivable and possible, the weakening and / or holding edges already during rolling of the metal strip from which the sheet metal pieces 16 are punched to introduce. In the course of the remaining steps of the procedure then no additional weakening and / or holding edges need to be introduced accordingly.
