Definitions
- the invention relates to a device for mechanical joining of flat sheets lying on top of each other using auxiliary joining parts according to the generic term of claim 1.
- Such a device for punch riveting is known from DE 196 30 488 A1.
- the tool set described there consists of a stamp holder on the stamp side Stamp and a hold-down device, the hold-down device via a spring system on the Stamp holder is attached.
- On the die side there is a die holder with inserted die and another hold-down device with spring system provided.
- the feeding of the auxiliary joining parts, especially the punch rivets, in the setting position or a standby position Poses problems. Just the one you want to set rivets Positioning accuracy could not be maintained if the auxiliary joining part passed through Gravity reaches the setting position.
- the object of the invention is therefore a device for mechanical joining of Flat sheets lying one on top of the other according to the preamble of claim 1 create a fast and accurate positioning of the auxiliary joining parts to one Joining allowed.
- a device for mechanical joining is flat sheets lying on top of each other using auxiliary joining parts with a Tool set created from at least one stamp and one die, in which the individual auxiliary joining part is accommodated under the working end of the stamp
- the auxiliary joining part is transported to the setting position and there via its feed puts.
- the stamp is therefore used as a positioning element.
- the feeding of the Auxiliary joining part takes place here outside the setting position, which means that none in the setting area additional space for auxiliary joining part feeders is required.
- the space requirement is limited to the diameter of the hold-down device.
- a direct shooting without Pre-storage is possible and there is no restriction regarding the Feed direction around the longitudinal axis of the punch.
- auxiliary joining section Holding the auxiliary joining parts by the auxiliary joining section allows that Auxiliary joining part can be guided over long closing distances, which makes it particularly good Component accessibility is ensured.
- auxiliary joining parts are independent of the material and the type of auxiliary joining part, even non-magnetic auxiliary joining parts can be the same Way such as magnetic auxiliary parts or auxiliary parts with threaded attachment supplied become.
- feed is also independent of the rivet length. Because of a Forced guidance of the auxiliary joining parts by the auxiliary joining piece and the stamp Set position can also be dispensed with a contribution of gravity.
- auxiliary joining part feeder over the supplied auxiliary joining parts a spring force holds non-positively at the working end of the stamp.
- translatory infeed movements do not occur between relative movements Stamp and hold down on.
- the feed movement of the stamp can be overlaid are from a rotational movement, which follows the auxiliary joining part, which is particularly for Auxiliary joining parts with thread attachment for screwing is of interest.
- the auxiliary joining piece can be easily mechanically formed, for example as a spring swing-away rocker, and thus low wear, so that the service life of Tool set not reduced by the integration of the auxiliary parts feeder become.
- stamp 1 and 2 show a first embodiment of a stamp 1 of a device for mechanical joining of sheet metal lying flat on top of one another with a Tool set consisting of at least one stamp 1 and one die.
- the die is in known manner with an anvil work surface in a clinching cavity formed, such as shown in Fig. 3 of DE 196 30 488 A1, and is therefore not shown further.
- the stamp 1 is arranged on an axially movable tool carrier 2, the Tool carrier 2 preferably has a fixed stop 3 and by means of a Linear motion generating drive 4 in a feed direction X with respect to a Component surface 20 of the sheets to be connected can be moved with selectable pressing forces is.
- the stamp 1 is surrounded at its working end 5 by a hold-down device 6.
- the Hold-down device 6 is fastened to the tool carrier 2 via a spring element 7 and is thereby carried adjacent to the stamp 1, i.e. the hold-down 6 follows this Stamp 1 in the feed direction X.
- the bias of the spring element 7 is adjustable. Due to the spring element 7, the hold-down device 6 is axially resilient and therefore resettable displaceable relative to the stamp 1 in the feed direction X when the Hold-down device 6 hits the component surface 20 and is held there during the Stamp 1 for performing a joining process with respect to the hold-down device 6 axially advances (see. Fig. 4 and 5).
- the hold-down device 6 surrounds the working end 5 of the stamp 1 in a sleeve-like manner and has one axially protruding from the working end 5 of the stamp 1 (in Feed direction X) hold-down head section 8, which a feed path Y in a axial through opening of the hold-down head section defined.
- the auxiliary joining piece rugs 10 is in the form of a resiliently swiveling away Starting position, swiveling, spring-loaded mechanical Tilting element formed, which is formed here by a two-armed lever.
- a Tension spring 14 engages arm 15 of the lever facing away from feed path Y, while the other arm 16 is a platter for receiving one each Auxiliary joining part 11 forms.
- the spring force of the tension spring 14 can be adjusted so that the original plate is horizontal in the starting position, i.e.
- auxiliary joining parts 11 perpendicular to the feed direction X, and then the distance to the working end 5 of the stamp 1 is greater than or equal to Length of the auxiliary joining parts 11 used, which is via the feed channel 9 and one Auxiliary joining part feed chamber 12 is supplied with the associated entry opening 17 in the hold-down device 6 and can be accommodated by the auxiliary joining piece 10.
- the tension spring 14 is set such that the arm 16 of the auxiliary joining piece 10 pulled at least slightly in the direction of the working end 5 of the stamp 1 is such that the remaining distance is smaller than the length of the to be added auxiliary joining parts 11.
- auxiliary joining parts 11 of such Auxiliary joining part rugs are added, so they are spring-loaded against the Working end 5 of the stamp pressed by the auxiliary joining piece-rivet 10 and thus recorded safely and firmly.
- Feeding the auxiliary joining parts into the Auxiliary joining part feed chamber 12 can be under compressed air or with such a feed force take place, the force of which is sufficient, the spring force acting on the arm 16 Auxiliary joining part counteract so far that the auxiliary joining parts 11 from Auxiliary joining part rugs 10 are receivable.
- This holding function is with the Stamp feed can be maintained until the auxiliary joining parts 11 each have the component surface Touch 20 (see Fig. 4).
- the spring force of the tension spring 14 also determines a pivoting resistance of the Auxiliary joining part feeder 10, which is in the feed direction X from the feed path Y can be pivoted away in order to release it for the respective auxiliary joining part 11.
- the 1 and 2 is two-armed lever about an axis perpendicular to the cutting plane pivotable, the pivot axis 21 being outside the feed path Y and the hold-down device 6 has a lateral recess into which the auxiliary joining piece rag 10 can pivot into it.
- the tension spring 14 puts the auxiliary joining piece back into the Starting position as soon as the stamp 1 withdraws from the feed path Y.
- the stamp 1 and the hold-down device 6 can be surrounded by housings 18, 19 which are by means of an anti-rotation device 22 can be fixed relative to the punch 1, in particular for the locking of a feed line of the feed channel 9.
- the starting position of the hold-down device 6 in relation to the punch 1 is in particular given when the spring element 7 has the predetermined bias and no additional pre-tensioning when hitting the Component surface is present.
- auxiliary joining part 11 Via the feed channel 9, which can be formed by a hose, is initially an auxiliary joining part 11 is conveyed under the working end 5 of the stamp 1. That in Downholder 6 resilient mechanical tilting element 10 fixes the auxiliary joining part 11 in this position (see FIGS. 1 and 2).
- the drive 1 then moves the punch 1 including the hold-down device 6 with the auxiliary joining part 11 and the resilient mechanical tilting element 10 in Feed direction X towards the component surface 20 (cf. FIG. 3).
- the auxiliary joining part 11 by advancing the working end 5 of the stamp 1 against the resistance of the resilient mechanical tilting element 10 and with the same pivoting away from the stamp 1 along the feed path Y in the hold-down device 6 in the direction Component surface 20 pressed (see. Fig. 4).
- the auxiliary joining part 11 is now set by the working end 5 of the stamp 1 with a predetermined pressing force, the auxiliary joining part 11 by a feed up to Component surface 20 sets (see FIG. 5).
- the auxiliary joining part 11 is preferably around a punch rivet that punches the stamp-side sheet metal when setting and spreading under deformation of the sheet on the die side.
- Fig. 6 shows a second embodiment of a stamp 1 of a device for mechanical joining by means of auxiliary joining part 11, which differs from that described above differs in that an additional duct 23 which can be pressurized with compressed air is provided, which opens into the feed channel 9 and for more precise positioning of the Auxiliary joining parts 11 in the auxiliary joining part feed space 12 are used.
- the additional channel 23 is preferably a blow channel that can send blow pulses. Via the feed channel 9 needs the auxiliary joining part 11 by means of the resilient mechanical tilting element 10 to be roughly pre-positioned at the working end 5 of the stamp 1.
- a time-shifted blowing pulse which is supplied via the additional channel 23 the auxiliary joining part 11 arrives in the exact position under the end of work 5. Otherwise the above statements regarding the first exemplary embodiment apply accordingly.
