Definitions
- the invention relates to a method for punching and packaging of stamping sheets after in the preamble Of claim 1 further defined type.
- a method and an apparatus for punching and packaging stamped sheets are known from DE 31 47 034 A1 known.
- the welding device can not be continuous work, making the welds only of a very limited shelf life.
- Another one Disadvantage of this known welding device is that a part of the laser optics of the welding device within of the tool is attached and on the same remain or with each tool change in consuming Way to be remounted and aligned got to.
- DE 26 05 983 C3 and DE 26 30 867 C2 describe other devices for stacking and packaging of stampings, wherein by means of a mandrel, a Slider, a cylinder / piston unit and a Ratchet intermediate stack formed from the punching plates become.
- a disadvantage of these devices is that during conversion on other punching plates the spikes in more complicated Way must be exchanged.
- the object of the present invention is a method for punching and packaging stamped sheets to create, by means of which of the stamped sheets individual sheet stacks can be separated in such a way that the stacks of sheets have a very exact height.
- the manufacture of sheet stacks with different Heights or with different numbers Single sheets should be possible in a very simple way be.
- the separator with the At least two wedge elements can be the separation of a Sheet stack of desired height from the in the receiving shaft located individual sheets in very be achieved in a simple and accurate manner.
- the wedge elements namely according to the invention in a standing stack and not, as in the im Separators described in the prior art Intended in the from the die into the receiving shaft falling sheets.
- the wedge elements results in accuracy the height of the separated laminated core of plus / minus a stamped sheet. This accuracy can be achieved by a more or less strong penetration of the wedge elements be increased in the stack of sheets. Depending on how far the wedge elements in the radial direction in the stack penetrate, namely, the sheets more or less strongly compressed and it can thus on the Height of the sheet pile are taken into account, though the number of individual sheets after the engagement of the Wedge elements per se is no longer changeable.
- Invention in a particularly advantageous embodiment of Invention can be provided that in the field of Receiving shaft or under the receiving shaft one Connecting device for connecting the separate, individual laminated cores is provided.
- the separation and then connecting the laminated cores be carried out without punch interruption.
- FIGS. 1, 2 and 3 show a device 1 for punching and packaging preferably round punching plates 2, which by a tool shell or a Stamp 3 and cooperating with the stamp 3 Tool lower part or a die 4 off a metal strip 5 produced in a conventional manner become.
- stamping plates 2 with a different geometry.
- the support element 7 has on its underside a lifting device 9, through which the support element 7 during the punching of Punching plates 2 can be moved down. So is ensured that constantly punched new punching plates 2 be and get into the receiving shaft 6 can.
- the lifting device 9 also able, the support element 7 again when needed to move upward in the direction of the die 4.
- the lifting device 9 can be electrical, be designed pneumatically or hydraulically and with a control, not shown, of the punch 3 in Connection and so at each stroke of the punch 3 moved by the thickness of a punching plate 2 down become.
- a Clamping device 10 through which the punching plates. 2 can be kept.
- the clamping device 10 has at her the punching plates 2 facing area two opposing prism-shaped holding elements 11 on.
- the holding elements 11 are via connecting elements 12 each connected to spindles 13, the through at the clamping device 10 located Drive devices 14 are driven. So can the prism-shaped holding elements 11 in the direction of Punching plates 2 are moved.
- the two drive devices 14 control technology with each other to pair.
- the clamping device 10 has the task to ensure that the punching plates 2 in the movement of the support element 7 does not fall down. For this reason, the holding elements 11 are in two parts each with an upper part 11a and a lower part 11b educated.
- a Separator 16 is provided, which at their the Punching plates 2 facing side two opposite each other Wedge elements 17 has.
- Each wedge element 17 each has a drive device 18 a spindle 19 for adjusting the separator 16 to different diameters of the punching plates 2, a drive device 20 with a spindle 21 for Adjusting the height of the wedge elements 17 in the direction a longitudinal axis 22 of the receiving shaft 6 and respectively a drive device 23 with a spindle 24 for engaging the wedge elements 17 in the sheet stack 8 on.
- the longitudinal axis 22 thus extends in the punching direction or also forms the longitudinal axis 22 of the punch third
- the drive devices 18 are located here the support element 7 and move over the spindles 19, the drive means 20 and 23 perpendicular to the longitudinal axis 22.
- the drive means 20 are also arranged on the support element 7, wherein their spindles 21 in the vertical direction, that is parallel to the longitudinal axis 22, are arranged.
- the drive means 23, whose Spindles 24 are parallel to the spindles 19, are each mounted on a plate 25, which, like described above, by the drive means 20th can be adjusted in height. All drive devices 14, 18, 20 and 23 can both electrically, pneumatically and hydraulically formed be and the associated spindles 13, 19, 21 and 24 may each be controlled by the controller, e.g. a known one NC control, the device 1 are controlled.
- the drive means 14, 18, 20 and 23 equipped with the spindles 13, 19, 21 and 24, can also linear drives as drive devices 14, 18, 20 and 23 may be provided.
- the engagement of the wedge elements 17 in the sheet stack. 8 can by a limit switch, not shown the support element 7 are initiated, which a certain way of the support element 7 down and thus reports a certain amount of sheet stack 8.
- the laminated core 8a is then passed through the process the support element 7 down to two in Fig. 4th illustrated, designed as a welder 27 Passing devices passed and through welded together the welders 27 at its periphery. As described above in this time the punching plates 2 held by the clamping device 10.
- the welding devices 27 are opposite each other and each consist of a welding platform 28, two centering strips 29, a welding nozzle 30th and a drive device 31 with a spindle 32nd
- the welding devices 27 can laser, electrode or plasma welding equipment.
- the separator 16 is drawn in Fig. 4 rotated by 45 ° and therefore also recognizable. Instead of the spindle 32nd can also drive device 32 as a linear drive be educated.
- the punching plates 2 for example, therefore the welding devices 27 connected to each other the resulting firmly interconnected laminated cores 8a for the production of rotors or stators of To use electric motors.
- the support element 7 is rotatably formed or with a corresponding rotating device connected, so not shown grooves on the circumference the punching plates 2 very easily turned against each other and it can thereby be especially useful
- Asynchronous motors used laminated cores 8a with Oblique grooves and oblique weld produced become.
- the punching plates 2 rotated accordingly against each other come to rest on the support element 7, but what can be carried out in a conventional manner.
- the laminated cores 8a to provide with oblique grooves and yet straight to weld.
- Fig. 5 shows an enlarged view of a part the welding device 27. Here are the welding platform 28 and the centering strips 29 better recognizable.
