Definitions

the invention relates to a device for punching and packaging of punched sheets according to the in the preamble of claim 1 defined in more detail. Furthermore The invention relates to a method for punching and packaging of punched sheets according to the in the preamble Art defined by claim 19.
DE 28 39 928 A1 describes a device for Conveying, stacking and packaging of Sheets of electrical machines known in which a welding device is attached below the die is continuous to the sheets continuously to be welded and applied as a tape from the press.
the welding device cannot be continuous work, whereby the welds only from have a very limited shelf life.
Another one The disadvantage of this known welding device is that part of the laser optics of the welding device inside of the tool is attached and to the same remain or more complex with every tool change Way to be reassembled and aligned got to.
DE 26 05 983 C3 and DE 26 30 867 C2 describe further devices for stacking and packaging of stamped parts, by means of a mandrel, one Slider, a cylinder / piston unit and one Ratchet intermediate stack formed from the stamped sheets become.
the object of the present invention is a device for punching and packaging punched sheets to create, by means of which of the punched sheets individual sheet stacks can be separated in such a way that the sheet stacks have a very exact height.
the manufacture of sheet metal stacks with different Heights or with different numbers Individual sheets should be possible in a very simple manner his.
the wedge elements result in accuracy the height of the separated laminated core of plus / minus a punching sheet. This accuracy can be determined by a more or less penetration of the wedge elements be raised in the sheet stack. Depending on how far the wedge elements in the radial direction in the stack penetrate, namely the sheets become more or less strongly compressed and it can thus on the Height of the sheet stack can be influenced, though the number of individual sheets after indenting the Wedge elements themselves are no longer changeable.
the separation according to the inventive method and then connecting the laminated cores can be carried out without interrupting the punching.
a receiving shaft is located below the die 4 6, in which the punching plates 2 fall and open one at the lower end of the receiving shaft 6 itself located support element 7 in the form of a stack of sheets 8 can be stacked.
the support element 7 has on its underside a lifting device 9, through which the support element 7 during punching the Punching plates 2 can be moved down. So is ensures that new punching plates 2 are constantly punched and get into the receiving shaft 6 can.
the lifting device is 9 also able to rest the support element 7 if necessary to move upwards in the direction of the die 4.
the lifting device 9 can be electrically be designed pneumatically or hydraulically and with a control, not shown, of the stamp 3 in Connect and so with each stroke of the punch 3 moved down by the thickness of a stamping plate 2 become.
the clamping device 10 Inside the receiving shaft 6 there is one Clamping device 10 through which the punching plates 2 can be held.
the clamping device 10 has on their area facing the punching plates 2 two opposite prismatic holding elements 11 on.
the holding elements 11 are via connecting elements 12 each connected to spindles 13 which by located on the clamping device 10 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 in terms of control technology to couple.
the clamping device 10 has the task to ensure that the punch plates 2 when moving 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.
the drive devices 18 are located here the support element 7 and move over the spindles 19 the drive devices 20 and 23 perpendicular to the longitudinal axis 22.
the drive devices 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. Let her through the wedge elements 17 adjust in height, which when they engage in differently high sheet metal packages 8a leads.
the drive devices 23, the Spindles 24 run parallel to the spindles 19, are each mounted on a plate 25 which, like described above, by the drive devices 20 can be adjusted in height. All drive devices 14, 18, 20 and 23 can both electrically, pneumatically and hydraulically trained be and the associated spindles 13, 19, 21 and 24 can each be controlled by the controller, e.g. a known one NC control, the device 1 can be controlled.
the controller e.g. a known one NC control, the device 1 can be controlled.
the drive devices 14, 18, 20 and 23 can be equipped with the spindles 13, 19, 21 and 24 also linear
the engagement of the wedge elements 17 in the sheet stack 8 can by a limit switch, not shown the support element 7 can be initiated, which one certain way of the support element 7 down and thus reports a certain height of the sheet stack 8.
the laminated core 8a is then through the process of the support element 7 downwards on two in FIG. 4 shown, designed as welding devices 27 Leads passed and through the welding devices 27 are welded together on its circumference. As described above at this time the punch plates 2 held by the clamping device 10.
the welding devices 27 lie opposite one another and each consist of a welding platform 28, two centering strips 29, a welding nozzle 30 and a drive device 31 with a spindle 32.
the welding devices 27 can be laser, electrode or Be plasma welding equipment.
the separator 16 is drawn rotated by 45 ° in FIG. 4 and therefore also recognizable. Instead of the spindle 32 can also drive device 32 as a linear drive be trained.
the stamping plates 2 are therefore, for example the welding devices 27 are connected to one another the resulting laminated core packages 8a for the manufacture of rotors or stators from To be able to use electric motors.
the support element has the ability to weld the laminated core 8a 7 two opposite recesses 33 on which the free passage of the laminated core 8a allow past the welding devices 27.
the support element 7 is designed to be rotatable or with a corresponding rotating device connected, so not shown grooves on the circumference the punching plates 2 very slightly twisted against each other be and it can in particular Sheet metal packages 8a were used with asynchronous motors Oblique grooves and oblique weld seam made become. It must be ensured that the punch plates 2 are rotated accordingly come to rest on the support element 7, but what can be carried out in a manner known per se. Of course, it is also possible to use the laminated core 8a to be provided with oblique grooves and still 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 can be seen better.
