Definitions

  • the invention relates to a numerically controlled groove punching machine with a sub-apparatus which can be rotated step by step about an axis of rotation depending on the ram stroke, and which can be overlaid gradually by means of further actuators in two crossing directions perpendicular to the axis of rotation.
  • Such a groove punching machine is known for example from DE-PS 16 27 227 for grooving dynamo sheets with a very large radius, which are broken down into circular ring segments.
  • This known slot punching machine is now designed in such a way that a resulting movement of the dividing device is produced per tappet stroke, which corresponds to a rotary movement about a center of the circle lying far outside the dividing device.
  • the invention is based on the object, with the aid of the known state of the art, to design a numerically controlled slot punching machine by means of which a manufacturing system can be constructed with which finished laminated cores for rotors and stators of electrical machines are produced automatically, without manual intervention can.
  • a numerically controlled, automatic multiple tool set is provided, which is particularly equipped with stator groove / separating, rotor groove and ventilation hole tools, and that the tools of the multiple tool set can be controlled individually and brought into effect according to the work steps to be carried out.
  • a numerically controlled slot punching machine is expediently provided with an automatic unstacking, loading, unloading and unstacking device which can be formed, for example, by numerically controlled handling machines.
  • a numerically controlled groove punching machine designed according to the invention enables the automated production of grooved sheets for electrical machines of almost all known types. e.g. Machines with diagonally grooved sheet packs, with conical sheet packs etc.
  • a numerically controlled groove punching machine 10 is shown, which is equipped with a multiple tool set 11.
  • the multiple tool set 11 here consists of a ventilation hole tool 12. B. for stator ventilation holes, a stator groove and separating tool 13, another ventilation hole tool 14, z. B. for rotor ventilation holes, and a rotor grooving tool 15.
  • the tools of the multiple tool set 11 can be moved on a curved guide track 16, the tools brought into the working position with the table or the plunger can be locked by suitable means known per se.
  • the numerically controlled slot punching machine 10 is further provided with a partial apparatus 17 which can be rotated step by step by means of an actuator (not shown in more detail).
  • the dividing device 17 itself can be moved horizontally and almost parallel to the end face of the numerically controlled slot punching machine 10 on a first path 18 and horizontally and almost at right angles to the first path 18 on a second path 19. Furthermore, an unstacking station 20 is provided for the non-grooved blanks 21 to be processed, from which a likewise numerically controlled handling machine 22 orients and / or rotates the blanks 21 in a loading position 23 to the sub-apparatus 17 in accordance with a known double-blank control. An unloading position 24 is another handle Exercise machine 22 assigned, the finished stator plates 25 to a stator stacking station 26 and finished Hotorbleche 27 to a rotor stacking station 28 in accordance with the groove pattern.
  • a unstacking station 20 ′ can be provided, whereby the loading and unloading of the sub-apparatus 17 is possible with only one handling machine 22.
  • the numerically controlled slot punching machine 10 itself can be moved in the direction of the tracks 18, 19, while the dividing device 17 is arranged in a stationary manner.
  • the example shown in FIG. 2 also includes a numerically controlled slot punching machine 10, the body of which, however, is more protruding than the slot punching machine 10 according to FIG.
  • the multiple tool set 11 also has ventilation hole tools 12, 14, a stator groove and separating tool 13 and a rotor groove tool 15.
  • the dividing apparatus 17 can be moved on the tracks 18, 19, while the unstacking station 20, the handling machines 22, the stacking stations 26, 28 and the alternatives shown in FIG. 1 are correspondingly present in the example according to FIG. 2.
  • the multiple tool set 11 is constructed equivalent to that of the example described in FIG. 1, but with a straight guide path 16 arranged tangentially to the dividing device 17 for the tools 12, 13, 14, 15 is.
  • the guideway 16 and the tools 12, 13, 14, 15 of the multiple tool set 11 are designed as a tool changing device known per se.
  • the tools 12, 13, 14, 15 are moved so that the first track 18 is identical to the guide track 16 of the multiple tool set 11.
  • the loading position 23 and the unloading position 24 are identical and the handling machine 22, the unstacking station 20, the stator unstacking station 26 and the rotor unstacking station 28 correspond in structure to the above described examples from FIGS. 1 and 2.
  • the guideway 16 is designed as a straight line.
  • the remaining structure is identical to that of the embodiment according to FIG. 1.
  • Un-grooved boards 21 are ready to be unstacked in the unstacking station 20.
  • an un-grooved board 21 is unstacked, possibly oriented by means not known in more detail, known per se and rotated by a predetermined angular amount.
  • the circuit board 21 is transferred to the sub-apparatus 17, which is moved to the working position with the circuit board 21 on the tracks 18, 19 via actuators (not shown).
  • the ventilation hole tool 12 is in action for the stator and cuts into the circuit board 21 after gradual rotation of the dividing device 17. That is, ventilation holes for the stator in accordance with the programmed hole pattern.
  • stator groove and separating tool 13 is exchanged for the ventilation hole tool 12, in which the stator groove and separating tool 13 is brought into operative engagement, for example by locking means, by means of an electric drive.
  • a positioning driven motor is not necessary for this.
  • the stator slots are also cut according to the programmed stator slot pattern.
  • the stator 25 is also separated from the still unprocessed rotor plate 27. After this machining run has ended, another tool change takes place. the ventilation hole tool 14 for the rotor 27 is brought into operative engagement.
  • the partial apparatus 17 has been moved into the unloading position 24 in a rapid traverse, the stator plate 25 has been removed by the handling machine 22 and stacked on the stator stacking station 26.
  • the dividing head 17 with the unprocessed rotor plate 27 is immediately moved back into the working position, and the ventilation holes are introduced into the rotor plate 27 with the ventilation hole tool 14.
  • the last machining run takes place, in which the rotor grooves are cut into the rotor plate 27 according to the program.
  • a great advantage of a slot punching machine according to the invention is given in that the plates 21 can be finished in one clamping on the dividing head 17 and thus laminated cores can be produced from stator plates 25 and rotor plates 27, which fit each other exactly, without additional selection criteria and / or reworking required are.
  • Sheet metal packages for special motors with, for example, angled grooving can be realized simply by moving the sub-assembly 17 slightly positioned in the direction of the first path 18 in the case of the examples in FIGS. 1, 2 and 4, while in the case of the example in accordance with FIG. 3 the tool can be moved even positioned.
  • the pole wheel 30 has four salient poles 31. those on the outside with grooves 32 are provided.
  • the contours of the magnet wheel 30 differ. how easy to see. considerably from conventional stator and rotor sheets. These contours are now punched out with the contour cutting tool 15 '. with which both the inner rectangular recesses 33 and the outer contours 34 can be punched.
  • the contours 34 do not correspond to the radius of the unprocessed blank 21, but each have a greater curvature.
  • the contour cutting tool 15 ' is provided with a groove punch 35 which is shortened compared to the other cutting edges.
  • the slot punching machine 10 can also be equipped with only one contour cutting tool 15 ′ instead of with a multiple tool set 11.
  • the dividing device 17 can move to any position within the framework of the tracks 18, 19 and can be rotated through 360 degrees, the plate 21 can assume any position with respect to the contour cutting tool 15 '. so that with relatively simple means, magnet wheels 30 equivalent to rotor and stator laminations can be produced.
  • the multiple tool set 11 can also have several independent contour cutting tools that are used instead of the tools 13, 14.
