- a crimping device for sheets and a method for crimping sheets by means of a hemming, in particular for body panels in vehicle construction, according to the preamble of the claims 1 and 12.
- Such a device and a method are out FR-A-2296519.
- a flanging device is known from DE 19801561, in which a electromechanical drive of the flanging bed both for the offset stroke between the crimping jaws and the working stroke is proposed.
- the Bördelbacken are pivotally mounted on the machine frame and are moved by means of pneumatic cylinders.
- the crimping device stands for the duration of Maintenance work still.
- the invention is therefore based on the object, a hemming to which require little time for maintenance and change of the Bördeltechnikmaschinectiones needed for simple, low-maintenance drives.
- the hemming tool is a self-contained, transportable unit that their workpiece-specific settings and adjustments regardless of whether it is in the crimping device or not. Both for the Tool maintenance as well as for the tool change, the crimping tool quickly and easily removed from the crimping device and through another Flaring tool to be replaced. Necessary work on the hemming tool are performed outside the crimping device while on the Beading with the other crimping tool another workpiece can be edited. After a renewed introduction and attachment of the Bördeltechnikmaschinemaschinees in the base frame is the hemming again immediately ready for use.
- the base frame contains all not workpiece-specific Components, these are above all the drives for flanging bed and crimping jaws, and it absorbs all forces occurring during the curling.
- the interfaces for the transmission of driving forces are modular, so that the same Drives without modification can be used for different crimping tool can.
- a crimping jack In the base frame a crimping jack is arranged, the driving force on the Flaring bed transmits, the drive of the crimping jack both hydraulically, can be done pneumatically or electromechanically.
- the flanging bed is included firmly connected to the crimping jack, wherein the connection is made manually by z. Legs Screw connection or is ensured by an automatic locking. In the latter case, the hemming bed itself centers by means of suitable Recordings at the first stroke of the crimping lever after installation of the Flanging.
- An embodiment of the invention provides that the hemming drive a replaceable Unit is essentially one attached to the base frame Drive base plate, the movable, guided in the base frame crimping, which carries the Bördelbettt, and a drive between the drive base plate and Crimping jack included.
- Another embodiment of the invention provides the required large Offset stroke between the crimping jaws by means of an electrically driven Spindelhubvorraum and the small working stroke for the Bördelvorgarig means one or more compressed air cushion, wherein the Spindelhubvorides during the working stroke by a Locking mechanism is protected from damage to the spindle.
- An advantageous embodiment of this embodiment provides that the Flare lifter, on which the flanging bed rests, is part of the screw jack.
- the entire Spindelhubvorides is including her Locking mechanism arranged on the compressed air cushion, so is at every working stroke. Because the airbags at the bottom of the Base frame are arranged, the crimping jack with a large Height to be executed.
- the resulting long guideways between the crimping jack and the base frame ensure the guidance of the crimping jack even with changing force application points due to Workpiece tolerances or different crimping tools.
- the base frame has a continuous in the horizontal direction Tool holder of at least the size of the hemming tool. This allows the crimping tool from any page in the base frame be pushed in and out of the base frame.
- the tensioning of the Flaring tool in the base frame may vary depending on the required Tool change time as manual screw connection or fully automatic done by means of electromechanical clamping elements.
- the base frame Changeover tables mounted on one or both sides of the tool holder. There The crimping tools can be serviced directly or for onward transport to get prepared. In the shuttle tables are also the devices for Pulling out or pushing the crimping tools arranged.
- a particular embodiment of the flanging device sees the Drives for the flanging jaws in the base frame laterally on the Tool holder before.
- the drive can ever according to the position of the slider in the flanging tool directly or via a crooked Level.
- the crimping slides are in Bördeltechnikmaschine corresponding reset devices such as inclined planes, Druckfedem or the like provided.
- a further embodiment of the crimping tool according to the invention provides a Base plate and a cover plate in front, both with Abstandstandsem to the Corners form the tool frame. Located between the base and cover plate the movable crimping slides. In the middle, the base plate has a Breakthrough of at least the size of the crimping bed on. In this Breakthrough will be the flaring bed during tool change and Transportes fixed, the crimping bed is then designed so that it does not after protrudes below the contour of the base plate.
- Both the cover plate of the hemming tool and the top of the Base frame have a breakthrough of at least the size of Workpiece through which the crimping tool from above with the workpiece can be loaded.
- the workpiece itself is carried through in the crimping bed Held down during the crimping process.
- the can Retainer integrated in the crimping tool or on top of the Base frame can be arranged, or the function of the hold-down can completely from the robot arm, which also the hemming device with the workpiece loads, be taken over.
- Bördelbacken For the maintenance of Bördelbacken is for the Bördelbett a lowered Position provided in the base frame. This allows the crimping tool without the crimping bed should be removed from the base frame. This position is intended for short-term maintenance work on the flared jaws and allows easier access to these.
