But there are also more than two magnets or even a magnet possible.
- the at least one magnet is a permanent magnet or an electromagnet.
- the advantage of a permanent magnet is that it is a simple device that can be operated fail-safe and maintenance-free.
- the advantage of an electromagnet is that depending on the application, the holding force of the at least one punching plate can be adjusted.
- not only one, but also two, three or more than three punching plates can be attached to the adapter of the punch. This has the advantage that, for example, only parts of a punching can be changed and thus any changes to the punching can be made, so that there is a great deal of flexibility and a high degree of freedom. Interchangeability of the punching plates.
- the adapter has at least one positioning pin, wherein the positioning pin in at least one
- Punching is quickly and easily positioned when the punched sheet, for. is placed on the at least one positioning pin.
- the positioning pin may e.g. engage in a bore or groove of the punching sheet around the punching sheet
- two positioning pins are provided, on which the punched sheet is inserted, so that the punching sheet is automatically brought by the positioning pins in a desired position.
- any suitable number of positioning pins is possible, for example also three, four, five or more than five positioning pins.
- Another advantageous embodiment is that, for example, two positioning pins are present, each having a different cross-section, for example round and square and / or a large and a small diameter, so that it is ensured that the punching plate can be positioned in only one position , Accidentally incorrect positioning of the punching plate on the adapter is thus excluded.
- the at least one positioning pin ensures that the at least one
- Punching plate with the required accuracy can be changed quickly and thus a precision check after a change significantly reduced or accelerated.
- positioning pin offers, for example a so-called dowel pin.
- a further advantageous additional and / or alternative embodiment of the invention is that the adapter has a geometric shape that matches the geometric shape of the punching sheet to position the punching sheet.
- the advantage is that the stamping sheet is only in a certain position in. the adapter can be inserted. This is achieved by having the adapter e.g. has a circular edge, the edge being attached to e.g. a place is interrupted. The punching plate with a correspondingly large circular edge is inserted into the edge of the adapter so that a projection of the punching plate fits exactly in the place where the edge of the adapter is interrupted, so that the punching plate can be repositioned accurately.
- all other geometric shapes for the adapter and the blanking plate are possible to position the blanking plate in the adapter according to the invention, e.g. a diamond-shaped, an oval and / or a triangular shape.
- the adapter has at least one recess to change the punching sheet by hand without the use of technical aids.
- the advantage of the recess is that the punching plate can be easily grasped and changed with the fingers. The use of tools can be completely dispensed with. Thus, a simple and quick change of at least one punching plate is possible.
- the at least one magnet has a holding force in the range of 10 to 100 Newtons. This has the advantage that the punching plate can be easily changed both by hand and so firmly attracted by the at least one magnet of the adapter that it can not be solved by the adapter when punching.
- Magnets in an adapter the individual magnets have different holding forces to allow easy hand switching.
- a further advantageous embodiment of the invention is that the punch has two adapters, wherein the two adapters are arranged opposite, so that the two adapters move towards each other for punching the data carrier.
- the advantage is that the card-shaped data carrier from both sides, i. is punched from a front and a back. The used
- Punching plates can have identical or different punched profiles.
- the punched profiles penetrate into the card-shaped data carrier during punching as a function of a set punch depth.
- Figure 1 shows the principle of the device according to the invention in a side view
- Figure 2 shows a plan view of a card-shaped data carrier and an adapter located above a punch.
- FIG. 1 shows the principle of the invention in a side view.
- Card-shaped data carrier 2 is punched by means of a first punching plate 4 and a second punching plate 6.
- the first stamped sheet 4 has a first stamped profile 14, e.g. a geometric shape of the disk, on.
- the second stamped sheet 6 has a second stamped profile 15.
- the first and the second punching plate 4 and 6 may have the same or different punched profiles 14 and 15.
- Each punching plate 4, 6 may have at least one punched profile 14, 15.
- Each stamped sheet 4, 6 is attracted by means of at least one magnet 16, 18 and thus attached to an adapter 8, 10.
- the adapter 8, 10 is connected to a punch, wherein the punch was not shown here for reasons of clarity.
- the first stamped sheet 4 has a first stamped profile 14, e.g. a geometric shape of the disk, on.
- the second stamped sheet 6 has a second stamped profile 15.
- Stamped sheet 4 attracted by a first magnet 16 and thus fixed to the adapter 8.
- the second stamped sheet 6 is attracted by a second magnet 18 and thus secured to the adapter 10.
- the holding force of a magnet 16, 18 is advantageously in the range of 10 to 100 Newton.
- At least one magnet 16, 18 is provided per adapter 8, 10.
- two, three or more than three magnets per adapter are possible.
- In the disk 2 is punched from both sides, so that a defined material thickness 12 remains.
- the material thickness 12 is adjustable depending on the application and determines the necessary force to break the particular shape.
- FIG. 2 shows the data carrier 2 in a plan view with the adapter 8 located above the data carrier 2.
- the person skilled in the art recognizes that the corresponding adapter 10 with stamped sheet metal is arranged on the other side of the data carrier 2, for which the following statements apply analogously.
- the adapter 8 has on its side facing the disk 2, the stamped sheet 4, which is shown in dashed lines, because it is covered by the adapter 8 and therefore is not visible.
- the punching plate 4 has a punched profile 14, for example, a geometric shape of a SIM card.
- the punched profile 14 is shown in dashed lines, since it is not visible in FIG. However, all other suitable geometric shapes of stamped profiles are possible.
- the stamped sheet 4 is tightened in Figure 2 by two magnets 24 and 26, which are arranged in the adapter 8, and thus attached to the adapter 8.
- the magnets 24 and 26 are arranged in the adapter 8, so not visible and therefore shown in phantom.
- the magnets 16, 18, 24, 26 erfmdungsloom be designed as permanent magnets and / or as electromagnets.
- the punching plate 4 can be attached only in one position on the adapter 8, the adapter 8 has two positioning pins 20 and 22, wherein the
- the different cross sections of the positioning pins 20 and 22 serve to ensure that the stamped sheet 4 can only be arranged in a single position on the adapter 8.
- the positioning pins 20 and 22 may be formed as dowel pins to allow a repetitive exact change of the punching plate 4 and ensure.
- the adapter 8 itself may be formed so that the stamped sheet 4 can be connected only in one position with the adapter 8. This can for example be realized by the adapter 8 has a certain geometric shape, such as a triangle, in which form only a stamped sheet can be used with a corresponding geometric shape, such as a stamped sheet with the geometric triangular shape of the adapter.
