Definitions

  • the present invention relates to a press forming tool having an upper tool and a lower tool according to the features in the preamble of patent claim 1.
  • Press forming tools for producing sheet metal components are known from the prior art.
  • a sheet metal blank is inserted into the press forming tool and then formed by moving an upper tool and a lower tool towards one another.
  • an upper tool is usually lowered with the help of a press ram, whereby when the upper tool comes into contact with the blank and the blank with the lower tool, the blank begins to be formed until the upper tool and lower tool are closed in such a way that a mold cavity remains between the upper tool and the lower tool when the blank is integrated.
  • the formed blank is then finally formed into the component to be produced by press forming.
  • hot forming and press hardening for hardenable steel alloys are known in the prior art.
  • blanks made of a hardenable steel alloy are heated to a temperature above AC3 so that they are completely austenitized. These heated blanks are then placed in the press forming tool and formed while warm. After completion of the press forming, with the press forming tool completely closed, the component is then preferably cooled so quickly in the press forming tool that quench hardening takes place. This process is also known as press hardening. If, due to the above-mentioned tolerances, there is no immediate and direct contact between the surface of the component in the press forming tool and the inside of the tool surfaces, the cooling capacity is reduced due to minimal air gaps in these areas and a lower cooling rate occurs.
  • JP2010042426A discloses a press forming tool according to the preamble of claim 1, in which a lever mechanism is used between the press ram and the tool clamping plate of an upper tool in order to distribute the force evenly, adapted to the deformation, on the workpiece to be formed.
  • the object of the present invention is therefore to show a press forming tool in which a compensation option for the upper tool and/or lower tool is provided, so that production tolerances that occur during press forming, in particular in the case of multiple tools, are reduced and, if necessary, better heat dissipation occurs during quench hardening.
  • the press-forming tool has an upper tool and a lower tool, which can be moved towards one another and, when the press-forming tool is closed, a mold cavity is formed between the upper tool and the lower tool.
  • a blank formed into a press-formed component comes to rest in a mold cavity, with the surface of the blank coming into contact with a tool surface of the upper tool and with a tool surface of the lower tool.
  • a tool clamping plate is arranged on a press ram and/or a press table, with an upper tool or lower tool movable relative to the latter being mounted on the tool clamping plate, with the incorporation of at least one spring-elastic adjusting element.
  • a press ram is thus provided in the area of the upper tool, the press ram having a corresponding receptacle for a tool clamping plate, the upper tool itself then being coupled to the tool clamping plate.
  • a press table is provided, on which the tool clamping plate is fixed and then, in turn, the lower tool on the tool clamping plate. The invention is described below in such a way that the tool clamping plate can be formed both on the press ram and on the press bed.
  • the tool clamping plate according to the invention with a spring-elastic actuating element is provided on the upper tool
  • a tool clamping plate with a spring-elastic actuating element is provided on the lower tool
  • a tool clamping plate is provided both on the upper tool and on the lower tool .
  • the embodiment variant of the elastic adjusting element on the upper tool is particularly preferred, precisely taking into account the tool costs incurred and the operating costs.
  • the particular advantage here is that only one tool, ie the upper tool, is resiliently mounted, which reduces the manufacturing costs of the tool. At the same time, this offers the advantage that no dirt falls into the spring-elastic adjusting elements due to the force of gravity when the tool is changed or the tool is operated.
  • the upper tool or the lower tool is now mounted so that it can move relative to the tool clamping plate.
  • the tool clamping plate first ensures that the spring-elastic adjusting elements distributed on the tool clamping plate transmit the press force homogeneously to the upper tool. If there is a misalignment, then due to the relative movement and the forming forces that are then distributed differently on the various spring-elastic adjusting elements, this will lead to a move up and thus to a homogenization of the forming forces to be transmitted.
  • the press-forming tool according to the invention is designed as a hot-forming and/or in particular press-hardening or quenching tool, almost full-area contact of the tool surfaces with the surface of the blank or the press-formed component produced is thus always ensured.
  • this results in the particular advantage that when quench hardening is carried out, it is ensured that the component has the desired quenching temperature and thus the desired hardened structure homogeneously and in particular in all required areas. If the cooling rates are lower due to minimal air gaps, either higher cooling capacities and/or larger time windows are used in order to reliably ensure that the components to be press-hardened have the desired hardness microstructure properties.
  • the tool clamping plate is coupled to the press table, in particular screwed, or the tool clamping plate is coupled, in particular screwed, to the press ram.
  • the press table would then be coupled to a tool clamping plate and the press ram would be coupled to a further tool clamping plate.
  • the spring-elastic adjusting elements are arranged in rows offset parallel to one another on the tool clamping plate.
  • a row consists of several, in particular 1 to 50, particularly preferably 2 to 30 and very particularly preferably 3 to 20 adjusting elements, in which case at least 2, preferably in turn 2 to 30, in particular 3 to 20 rows of adjusting elements are arranged offset parallel to one another.
  • the rows themselves are particularly preferably at the same distance from one another as the individual adjusting elements in a row. This results in a pattern of spring-elastic adjusting elements that is evenly distributed over the tool clamping plate, so that the press-forming force can be distributed correspondingly homogeneously.
  • the adjusting elements may be distributed on the tool clamping plate, in particular distributed asymmetrically. It would also be conceivable within the scope of the invention for the distribution of the spring-elastic adjusting elements to be adapted to the back of the contour of the upper tool or lower tool. Thus, for example, a special shape of the press-formed component to be produced can be taken into account. In addition, in areas where forming forces are concentrated, more spring-elastic adjusting elements, and therefore a greater number or density of adjusting elements per area, can be arranged in order to compensate for the occurrence of increased forming forces compared to areas in which only lower forming forces are necessary.
  • At least individual spring setting elements can be blocked. This would particularly preferably be the case with spring adjusting elements arranged in a row, so that, for example, an entire row can be blocked in each case. Within the scope of the invention, however, it would also be conceivable for individual spring setting elements to be blockable in a targeted manner.
  • the spring-elastic adjusting elements are designed in particular as mechanical springs.
  • helical compression springs are used.
  • disc springs, helical disc springs and/or sleeve springs are also conceivable.
  • an arrangement is then conceivable here in such a way that the spring-elastic adjusting elements themselves under prestress between the upper tool and the tool clamping plate or lower tool and Tool clamping plate are arranged. Appropriate prestressing is then necessary here, particularly during assembly or when changing the upper tool and lower tool.
  • the spring-elastic actuating element it is also possible for the spring-elastic actuating element to be designed as a pneumatic and/or hydraulic spring element. Two different operating variants are then conceivable for this.
  • the pneumatic and/or hydraulic spring element can be operated passively. This means that due to the spring characteristics, a corresponding spring characteristic curve is set with increasing press pressure and the press force is passed on to the sheet metal blank to be formed or to the formed component at the bottom dead center of the press and thus the locking force.
  • the spring-elastic actuating element can be designed as an actuator and also to be actively controllable.
  • the pressing force passed on via the spring-elastic actuating element can be increased again by applying an operating pressure and any remaining gap in the cavity between the tool surface and the surface of the component can be closed by the increased pressing force and an associated relative movement of the upper tool and /or close the lower tool.
  • a corresponding operating pressure is already applied to the spring-elastic adjusting elements while the press is being closed.
  • a damping bearing is particularly preferably arranged between a rear side of the upper tool and the tool clamping plate or between a rear side of the lower tool and the tool clamping plate.
  • the damping bearing is preferably a damping layer to avoid metal impacts.
  • the damping bearing prevents metal impact when the press forming tool is opened, so that there is no contact between the upper tool and the tool clamping plate or the lower tool and the tool clamping plate that would damage the production process.
  • the damping camp can in particular, for example, made of plastic or a rubber-like material and is applied in particular flat and/or in the form of strips. It can also be applied selectively.
  • the back of the upper tool or the back of the lower tool would come into contact with the mounting strips at least in some areas and then transmit the forming force directly and not just via the spring-elastic actuating element.
  • An undesired displacement due to excessive relative movement and/or undesired forming behavior of the blank is hereby avoided.
  • the lower tool or the upper tool, and in some cases both tools are each segmented, with the individual segments being mounted on the tool clamping plate so that they can move relative to one another. These are then also each mounted so that they can move relative to the tool clamping plate.
  • the invention provides that at least two upper tools or at least two lower tools are arranged next to one another on a tool clamping plate, the two upper tools or the two lower tools being mounted such that they can move relative to one another.
  • this means a multiple falling die, so that the same components can be produced due to the same upper dies and lower dies arranged next to one another or from one another but with one press stroke.
  • upper tools or lower tools that are different from one another are arranged transversely to the press ram or on the press bed, so that components that are different from one another can be produced with one press stroke.
  • the relative movement can in turn ensure that all components have the necessary degree of deformation during a press stroke and in particular the necessary system contacts for a press operation, so that the desired hardened structure can be set in a targeted manner.
  • a centering mandrel is arranged between the press ram and the press table, which guides the closing movement of the press ram and the press table linearly, in particular vertically, in the direction of the press stroke. This ensures that the relative movement due to the spring-elastic actuating element is mainly carried out exclusively in the direction of the press stroke and not transversely to the direction of the press stroke.
  • the centering mandrel is arranged between the upper tool and the lower tool, so that in particular it avoids a corresponding relative movement in the transverse direction to the press stroke.
  • the spring-elastic adjusting elements are provided with screw bolts that pass through and/or are integrated into the spring-elastic adjusting elements, so that it is possible to carry out tool assembly.
  • a corresponding pretensioning of the spring-elastic adjusting elements can be realized, in particular in the case of the screw bolts reaching through the adjusting elements during tool assembly.
  • the upper tool and the lower tool are particularly preferably mounted in a form-fitting manner on the respective tool clamping plate by means of sliding blocks, in particular by means of double-T sliding blocks.
  • the smallest possible tolerance or displacement, and therefore lateral guidance is provided in particular in the horizontal direction, with linear guidance taking place in the vertical direction, therefore in the direction of the press stroke, so that the upper tool or the lower tool, predetermined by the spring-elastic adjusting elements, moves relative to the tool clamping plate can move.
  • a second embodiment variant of the present invention provides that the upper tool and/or the lower tool are coupled to the tool clamping plate in a relatively movable manner by means of sliding blocks, wherein a sliding block has a guide section and an abutment section.
  • the sliding blocks are particularly preferably T-shaped for this purpose.
  • the T-leg forms the guide section, which at the same time also guides linearly in the vertical direction and avoids a relative movement transverse to the direction of the press stroke.
  • the cross bar of the T forms from an abutment section, so that a relative movement is limited when reaching the crossbar. If, for example, the tool clamping plate is described on the upper tool, it is coupled to the press ram.
  • a press forming tool 101 is shown in a side cross-sectional view.
  • the press forming tool 101 has a press ram 102 shown from top to bottom in the plane of the drawing, with the upper tool 103 not being shown being coupled to the press ram 102 .
