Definitions
- the invention relates to a folding device for reshaping a component, for example a Karosseriebeplankungsteils, with at least one movably held on a support member forming element and interface, which is in operative connection with the forming element to impart a feed movement to the at least one forming element.
- folding or crimping means the positive connection of two parts by crimping a flange.
- bodywork in particular an inner panel part with an outer panel part is thereby connected to one another.
- the outer sheet metal part may, for example, be a body shell.
- US 7 134 309 shows a folding device with a folding bed and four forming elements, which are arranged in corners of the folding bed to make a fold in the Bauteilck Schemeen.
- a kinematic drive which is arranged under the folding bed, all four forming elements are driven simultaneously, so that the folding takes place synchronously.
- the disadvantage here is that the forming elements are firmly attached to the folding bed, so that a collision-free loading of the folding bed with the component and a removal of the component from the folding bed must be ensured by appropriate handling.
- the object of the present invention is to provide a folding device, which allows a quick attachment to a folding bed and a simple operation.
- a folding device for forming a component, in particular a Karosseriebeplankungsteils, with at least one movably held on a support element forming element, at least a first interface, via which the device is fastened to a folding bed and a second interface with which the Device can be coupled to a handling device, and is in operative connection with the forming element in order to impose on the second interface a feed movement to the at least one forming element.
- the folding device according to the invention can, if necessary, be decoupled from the folding bed via the first interface if the folding bed is to be equipped with a component or the finished folded component is to be removed. This creates space for the component so that there is no danger of collision. Furthermore, it is advantageous that the second interface serves both to handle the device as a whole, as well as the drive of the actual folding operation.
- An advantageous embodiment of the invention provides that a plurality of forming elements are provided. It is expedient in this case if the plurality of forming elements differ in their folding contour. This is advantageous if different fold contours are to be provided at different component corner regions. Also, over the folding device with the plurality of forming elements, a multi-stage folding can be realized by, for example, a first forming element performs a pre-folding and a second forming element Fertigfalzen.
- An advantageous embodiment of the invention provides that each of the forming elements is assigned a first interface. This ensures that each forming element undergoes a force support and moment support on the folding bed via the first interface assigned to it.
- An advantageous embodiment of the invention provides that the second interface is connected via a transmission element in operative connection with the at least one forming element.
- the transmission element can advantageously be used to selectively set a transmission characteristic which is effective between the second interface and the deformation element.
- An advantageous embodiment of the invention provides that the transmission element for each of the several forming elements has a different transfer characteristic of a drive movement in the feed movement.
- a multi-stage folding can be realized via different transmission characteristics, so that a first forming element performs a pre-folding and a second forming element performs a finished folding.
- a first possible embodiment of the invention provides that the transmission element is formed as a contour disc, for transmitting a rotary drive movement in a translational feed movement.
- a contour disc for transmitting a rotary drive movement in a translational feed movement.
- a particularly space-saving drive is guaranteed because the handling device only has to perform a rotary motion.
- a second possible embodiment of the invention provides that the transmission element is designed as a pressure stamp, for transmitting a translational drive movement in a translational feed movement.
- a plunger for translational drive is advantageous if the handling device has no rotary drive in its manipulator. It is particularly preferred that a spring return acts on the plunger in an initial position.
- the object is further achieved by a method for forming a component with a folding device as described, with the following steps:
- Figure 1 shows a first embodiment of a folding device in a perspective view
- Figure 2 shows a first embodiment of a folding device in side view
- FIG. 3 shows a second embodiment of a folding device in a perspective view
- Figure 4 shows a second embodiment of a folding device in side view.
- FIG. 1 and 2 show a first embodiment of a folding device 10 for forming a component in a perspective view or in a side view.
- FIG. 2 shows the folding bed 1 schematically. The recorded in the folding bed 1 component is not shown here.
- the folding device 10 initially has a carrier element 12, which may be designed in the manner of a base plate. Forming elements 14 designed as shaped pieces are displaceably held in the guide lugs 16 on the carrier element 12 via the mold carrier 18. In the present case four forming elements 14 are arranged, wherein a deviating here before number can be provided.
- the folding device 10 has a number of the forming elements 14 corresponding number of first interfaces 20, which are preferably formed on the support member 12. Over each of the interfaces 20, the folding device 10 can be attached to the folding bed 1 and held by this.
- the first interfaces 20 may each comprise a coupling element 22 for this purpose.
- a second interface 24 is arranged, via which the folding device 10 can first be gripped by a handling device, not shown, for example a robot, and moved in space.
- a handling device not shown, for example a robot
- the folding device 10 can be moved relative to the folding bed 1, thus coupling a coupling element 22 of the first interfaces 20 of the folding device 10 with a coupling element of the folding bed 1 and thus to secure the folding device 10 to the folding bed 1
- the second interface 24 comprises a transmission element 26, with which a drive movement, which is initiated via the second interface 24, can be translated into a feed movement of the deformation elements 14.
- the transmission element 26 is formed as a contour disc, which is held about a rotational axis D rotatable relative to the carrier element 12.
- the transmission element 26 forms, as a contour disk, an outer circumferential surface 28 with a radial distance from the axis of rotation D which varies over the circumference.
- About the outer peripheral surface 28 is each of the forming elements 14 via a respective mold support 18 in operative connection and that the mold supports 18 are arranged in contact with the outer peripheral surface 28 and drive rotation of the transmission element 26, the changing radial distance of the outer peripheral surface 28 to the axis of rotation D as imprinted translational Zustellieri.
- the infeed movement is symbolized by the arrows Z.
- ram elements 30 may be provided.
- the changing radial distance of the outer circumferential surface 28 from the axis of rotation D can be seen, for example, from FIG. 2 and is symbolized by double arrows Li and L 2 of different lengths.
- the different radial distances L lead to a different transfer characteristic of the drive movement in the feed movement.
- Figures 3 and 4 show a second embodiment of a folding device 10 for forming a component in a perspective view and in a side view.
- the second embodiment will be described only with respect to their differences from the first embodiment.
- the second embodiment is characterized in that the transmission element 26 is designed as a pressure stamp.
- the drive movement is a translational movement, which is symbolized by the arrow T in Figure 4.
- the transmission element 26 forms, as a pressure stamp, drive flanks 32, each of which can be set at an angle ⁇ with respect to the direction of the drive movement.
- four drive flanks 32i to 32 4 may be provided, wherein each may have a different angle ⁇ to a 4 with respect to the direction of the drive movement.
- a spring return 34 can be provided, which acts on the plunger in an initial position.
