Definitions

  • the invention relates to a composite tool according to the preamble of claim 1 and a manufacturing method according to the preamble of claim 15.
  • Composite tools and in particular overall composite tools are usually characterized in that at least two technologically different machining processes are performed in one tool and in one press stroke. In other words, multiple operations or functions are integrated into a tool or machining step.
  • Commonly composite tools are used mainly for geometrically simple components, which are usually made of a metal strip.
  • the use of Intelverbundtechnikmaschineen is not common.
  • Body panels are typically manufactured in a series of operations of drawing, trimming, punching, and finishing in multiple dies or tool stages.
  • the finished molding can in particular represent a bending operation.
  • drawing the component base from a flat sheet metal blank is the first operation in the manufacturing process with line or transfer tools.
  • the drawing is typically a deep drawing, stretch drawing, or combined operation a tool. Subsequently, in operations separate from the drawing, the further steps are carried out such as punching, cutting and finishing.
  • Subsequent or finished molds are also understood to mean shaping operations, usually in the last tool stage.
  • a process of post-forming or finish-forming represents the folding.
  • the edge of the drawn and trimmed sheet metal part is "bent" by about 90 °.
  • Beveled shelves on sheet metal parts serve e.g. as Fügeflansche or as a preform for a crimping or Rollfalzoperation in shell, where the item is joined with others to an assembly. In most cases, the folding takes place in the last operation.
  • FIG. 16A schematically shows a known from the prior art operation sequence pull-trimming-folding on a body component K.
  • the Figures 16A and 16B show in each case the simple case in which all operations in the direction of a press can be performed.
  • a tool element bending strip
  • post-forming or finish-forming are, for example, the reference or calibration.
  • an already formed component is acted upon in order to locally influence its geometry.
  • imprints are introduced or radii are reduced.
  • the invention has the object to achieve a reduction in the total number of tools required for the production of a sheet metal component and this reduction in equipment costs and the development and procurement times and to shorten process chains.
  • the translationally adjustable blank holder secures the defined position and orientation of the waste piece to be separated in cooperation with the at least two-part die and, through its adjustability relative to the punch, ensures the integration of a cutting operation into the press stroke.
  • a “pressing of the two-part die and the punch against each other” is understood in particular to mean that the two-part die and the punch are displaced toward one another under the action of an adjusting force applied by a press (equipped with the composite tool) and an actual pressing of at least one Part of the at least two-part die against the stamp only with a time end of the drawing process takes place.
  • the outer die is pressed against the blank holder and a pressing of the inner die against the punch takes place only with the end of the drawing process.
  • the fact that the inner die and the outer dies on the first structure are adjustable relative to each other includes both that the inner die is adjustable relative to the outer die, and that the outer die is adjustable relative to the inner die. Due to the adjustability of the inner and outer matrices relative to each other on the first structure as well as through the interaction with the adjustable plate holder of the second structure, a separation of the waste piece can be realized in a particularly simple manner via the press stroke.
  • the outer die of the first structure may at least partially surround the inner die.
  • the outer die has a first form-fitting region and the blank holder has a second form-fitting region.
  • the scrap piece of the sheet metal blank is deformed (locally) during pressing via the first and second form-fit regions of the outer die and so that at least one region of the scrap piece engages positively in at least one of the first and second form-fitting regions and / or at least one of the first and second form-fitting regions engages positively in the waste piece.
  • the first and second positive locking areas can thus serve to fix the waste piece between the sheet holder and the outer die during pressing, although this is not mandatory.
  • the first and second positive-locking regions can be used, for example, as Projections and / or depressions may be formed. For example, a bulge is provided on the outer die for producing a bead corresponding thereto at the waste piece of the sheet metal blank.
  • the composite tool is thus adapted to simultaneously use a pressing force applied for forming the sheet metal blank to separate an outer edge of the sheet metal blank as a piece of waste and thus to trim the sheet metal blank. Possibly.
  • the edge of the sheet metal component is also finished, but at least deformed.
  • trimming and e.g. an edge bending or folding. Consequently, the first structure and the second structure can not only be set up with the pressing of the die and the punch against each other and also separate an outer edge of the sheet metal blank as a waste piece. Rather, the first structure and the second structure may also be arranged to reshape an edge portion of the sheet metal component on which a separation edge resulting from the separation of the waste piece is formed before or after the separation of the waste piece.
  • the edge portion of the sheet metal component, on which the separating edge is present bent before separating the waste piece or folded after the separation of the waste piece.
  • a press on which the composite tool is equipped with the first and second structures is then the sole drive for all tool functions, i. There are no other hydraulic or other actuators used to realize the trimming and finish molding.
  • At least one follow-up operation in the drawing tool can be integrated via the relatively adjustable inner and outer dies.
  • at least an external trimming of the sheet metal component is integrated into the drawing stage. This may in particular be a circumferential trimming, thus a complete trimming. It is also conceivable, however, to carry out only a first segment trimming in the drawing tool, which would be possible, for example, in the special case of pulling with open heads. Pulling and trimming are basically done in a continuous stroke of the composite tool.
  • the generated cut or trim edge can both represent the contour of the finished part, as well as in other operations, such as a folding or post-forming, further processed.
  • the composite tool according to the invention makes it possible to reduce the number of tools for the production of a sheet metal component by at least one operation.
  • the invention is in this case e.g. not limited to body parts for motor vehicles, but also extends to the production of other sheet metal components, in particular sheet metal components made of steel, aluminum or other materials.
  • edge trimming of the sheet metal blank is also to be separated from the setting of a relief slot in an internal waste area of the component, e.g. in a window opening.
  • a relief cut is raised during forming, which favors the material flow from "inside out".
  • this is only a linear cut, i. no trimming operation.
  • the area of the wound relief cut is cut out only in a downstream operation. Consequently, this is not the integration of a trim operation into the puller.
  • the composite tool integrates a circumferential outer component truncation in the drawing stage. Further operations may be integrated in possible developments in the drawing stage. These are e.g. to the integration of pulling, cutting and bending or pulling, cutting, folding and stamping. This makes it possible, for example, to realize the entire production sequence of a sheet metal component in the composite tool and in a press stroke converted therewith.
  • the proposed solution also differs from follow-on composite tools, which are characterized in that the manufacture of the components from a sheet metal strip (from the coil) takes place, which is pushed or pulled stepwise through a sequence of several tool stages. The finished component is only separated from the strip in the last step.
  • follow - on tools are used in usually only small to medium-sized, geometrically simple components manufactured in large quantities.
  • the composite tool hereby typically forms a component-specific pressing tool in which a sheet metal blank is formed globally. This is followed by a separation, preferably a shear cutting on the circumference of the three-dimensionally shaped geometry, no laser or water jet cutting in the horizontal plane.
  • the sheet metal component is not cut out, but a piece of waste cut from the sheet metal blank.
  • the blank holder on the second structure is adjustable relative to the punch in a loading position on the outer die.
  • the then occupied insertion position of the sheet metal blank is to be arranged with a peripheral portion on the sheet holder.
  • the sheet holder is adjustable relative to the punch in a different holding position to the insertion position, in which the separated from the sheet blank waste between the outer die and the blank holder is held.
  • the blank holder is displaced from the loading position under the action of the first structure and in particular of the outer die displaced with the first structure.
  • the waste piece of the sheet metal blank provided between the outer die and the adjustable sheet holder is hereby reshaped as required.
  • the separated waste piece is held in a defined position at the end of the press stroke by the plate holder which can be adjusted relative to the punch and can be displaced relative to the finished sheet metal component. This is particularly advantageous with regard to the removal of the waste piece from the composite tool.
  • the proposed composite tool is set up to simultaneously use a pressing force applied to reshape the sheet metal blank and thus also the press stroke to separate the piece of waste and, if necessary, to shape the edge of the sheet metal component.
  • the translucent adjustment of the first structure and the second structure toward one another can also lead to the sheet metal holder relative to the stamp and / or die inner and outer matrices are adjusted relative to each other.
  • the blank holder is thus not power-operated by an additional drive, for example, during the press stroke relative to the punch adjustable, but solely by the pressing force.
  • a relative movement of the plate holder to the stamp is thus caused by the adjustment of the first and second structures toward each other and the thus realized press stroke.
  • An additional (motor) adjustment is not provided for this purpose. The same applies to the alternative or supplementary intended adjustment of inner and outer matrices relative to each other during the pressing.
  • a stamp structure is additionally provided on the second structure, which is arranged between the blank holder and an insertion region for a cutting edge of the first structure.
  • the stamp construction against this background is opposite to a hold-down of the first structure.
  • the stamp construction can be spaced apart from the stamp and at the same time from the sheet metal holder (transversely to the adjustment direction of the sheet metal holder). In an alternative embodiment variant, however, the stamp construction can also be an integral part of the stamp.
  • first structure and the second structure of the composite tool may be arranged to cut off the waste piece by shearing with the pressing of the die and the punch against each other.
  • At least two-part die in which an inner die and an outer die are adjustable relative to each other, may be formed in a variant for the separation of the waste piece on the outer die a cutting edge or mounted a cutting edge.

  • the inner die is displaced counter to the adjustment direction with respect to the cutting edge, so that the cutting edge separates the scrap piece on further adjustment of the first structure, optionally adjacent to forming the separating edge the inner matrix.
  • the cutting edge is formed in a variant with a cutting bar (a) simultaneously when pressing the die and the punch against each other acts as a folding edge or (b) during pressing of the die and the punch against each other cooperates with a counter-holder and then as a folding bar against this Counterholder acts.
  • the cutter bar is e.g. for folding an issued and / or multi-stepped board when pressing the die and the punch against each other.
  • a cutting edge of the cutting bar has at least one first cutting edge section and at least one second cutting edge section, wherein, with respect to a direction pointing from the inner die to the outer die, the at least one first cutting edge section is on the inside and the at least one second cutting edge section is on the outside, such that an inner contour of the cutting edge and the at least one second cutting edge section define an outer contour of the cutting edge with the at least one first cutting edge section.
  • the protrusion of different cutting edge portions may prove to be particularly advantageous if two edge regions are to be provided on the component, of which an edge region is finished after drawing and trimming, while an adjoining edge region after pulling and trimming a laid-out board still a fold must be subjected. For these different edge areas then the movable cutting bar is designed accordingly different.
  • the at least one second cutting edge section of the cutting edge defining the outer contour projects with respect to the at least one first cutting edge section defining the inner contour, e.g. in an adjustment of the cutting edge, in which the cutting edge is adjusted against each other during the pressing of the die and the punch.
  • the at least one second cutting edge section of the cutting edge defining the outer contour faces the at least one first cutting edge section defining the inner contour, depending on the component geometry, process, sheet metal material and thickness, for example. by 0.5 mm to 3.0 mm before.
  • a board in the range of 0.7 mm to 1.4 mm is provided.
  • a cooperating with the cutting bar counter-holder may further be formed and provided, for a transition region of the cutting edge, where the cutting edge of the at least one first cutting edge portion merges into the at least one second cutting edge portion to act as a counter blade when pressing the die and the punch against each other.
  • a counter holder interacting with the cutting bar can be designed and provided to be displaced against one another by the cutting edge abutting the at least one first cutting edge section when the die and the punch are pressed together, after by means of the at least one second cutting edge section a trimming of the sheet metal blank was made. After completion of the trimming in a second edge regions and a transition region, the cutting edge therefore sits in the here first edge region on the anvil and begins to displace this with advancing press stroke against a defined force down.
  • the cropping in the first edge area is performed in advance and then peels over the transition edge area. Finally, the second edge area is cut and folded.
  • a cutting insert may be provided on a top or bottom blade at a transition region.

  • a shaping surface for embossing can be provided, for example, on the first structure on a cutting, bending or stamping strip and / or on the second structure on the stamp.
  • the cutting edge of the first structure, relative to which the inner die is adjustably mounted may also be formed with a cutting strip which simultaneously acts as a folding edge and as a molding strip for providing the embossment when the die and the punch are pressed To provide a stamped board of the edge portion of the embossment.
  • an (embossing) insert can be provided on the first structure by means of which an embossment in the component surface (and thus not on an edge flange), in particular a door grip recess, is introduced during pulling or after completion of the drawing.
  • the integration of a stamping process for the production of a stamping in the component surface in the press stroke can thereby achieve facilitate higher surface quality.
  • the sheet metal blank is still to a certain extent under biaxial tension from the drawing process and to be provided with the embossment component surface is between the punch and the inner die held. This biaxial tensile stress superimposes the stress states that result from the embossing process in and around the embossment and reduces the influence of the different unwinding lengths over the embossment.
