Definitions

  • the invention relates to a circular blade according to the preamble of claim 1.
  • Knives for performing perforations are known per se. From the EP 1 882 563 A2 a device with two circular knives is known, which are used for perforating corrugated cardboard.
  • the circular blades have on their outer circumference a sprocket whose teeth are sharp-edged.
  • the circular knives are placed on both sides of the corrugated cardboard and perforate the corrugated cardboard that is placed between them. A change in the depth of cut can be achieved by a change in distance of the circular blade to each other.
  • the object of the invention is to provide a circular blade, with the different depths of cut are possible.
  • a circular blade for performing a cutting path, with a knife body whose outer periphery has a ring gear, in which alternately teeth and interdental spaces follow one another with tooth reasons.
  • the knife body is formed from at least two partial blades, wherein the separation of the at least two partial blades is provided transversely to the axis of rotation of the knife body.
  • a first one of the dividing knives has a ring gear in which the teeth are not formed as cutting edges and the tooth bottoms are formed as cutting edges, and a second one of the dividing knives has one Toothed ring, whose teeth and tooth roots are formed as cutting edges.
  • the circular knife rolls along the cutting path on the surface of the material to be cut, e.g. Corrugated board, from.
  • cuts can be made in two cutting depths with the circular blade.
  • the at least two partial blades may have teeth and interdental spaces and be rotatable relative to each other about the axis of rotation of the blade body. If the at least two dividing knives are rotated relative to one another, different distances between the cutting edges of the dividing knives and thus different cutting depths of the knife can be set.
  • the cutting edges of the teeth may be formed so tangential to the circumference or along the circumference curved.
  • a cut can be made which is substantially perpendicular to a surface of the corrugated cardboard adjacent to the circular blade.
  • a pulling cut, in which a cutting edge is pulled through the corrugated cardboard in the cutting direction, which can lead to cracks and breakouts and the like, can be avoided.
  • the sprocket may be bevelled in the radial direction to the outside at least on a flat side of the knife body.
  • the sprocket may be chamfered on both flat sides of the knife body. This results in a defined, sharp cutting edge on the teeth and / or on the tooth base.
  • the first of the dividing blades may have a larger circumference than the second of the dividing blades. This defines a defined blade size.
  • One or more cutting edges with different cutting depths may be in the interdental spaces of the first Partial knife be provided whose tooth surfaces are not formed as cutting edges.
  • the teeth of the second of the dividing blades may be at least as wide that they fill the interdental spaces of the first of the dividing blades.
  • defined dimensions of the perforation and a defined positioning of the part diameter are accessible to each other.
  • the tooth bottoms of the second of the dividing blades may be at least as wide that they fill the interdental spaces of the first of the dividing blades.
  • defined dimensions of the perforation and a defined positioning of the part diameter are accessible to each other.
  • the toothed bodies of the dividing knives can have one or more marking means in order to display a first and / or second position of the dividing knives defined relative to one another.
  • the dividers can be positioned in a defined manner for different cutting depths to each other. This can be done advantageously by manual positioning by optical control using the one or more marking agents.
  • the circular blade according to the invention can be used in cutting or perforating machines, or in hand-held tools.
  • FIGS. 1 to 3 show for illustrating the invention an embodiment of a rotary drivable rotary blade 10 with different depths of cut.
  • the circular blade 10 has a knife body 12, which in the axial direction of part knives, here of a first part diameter 40 and a second part diameter 50, is composed by these are placed with their flat sides together.
  • FIG. 1 shows the circular blade 10 as a side view, the FIGS. 2 and 3 the dividers 40, 50 in isometric view. The dividers 40, 50 are rotated against each other.
  • the first dividing blade 40 has a disc-shaped meter body with a central opening 28, wherein on the outer periphery of the meter body a ring gear 48 is provided, in which alternately teeth 42 and interdental spaces 44 equally spaced follow one another.
  • the teeth 42 are formed in plan view substantially as rectangular wedges.
  • a pin is provided as a marking means 62, with which a rotational position of the part diameter 40, based on its axis of rotation, can be determined.
  • the marking means may be designed differently in a suitable manner, for example as a groove, notch or the like.
  • the second dividing blade 50 has a disc-shaped meter body with a central opening 28, wherein on the outer circumference of the meter body a ring gear 58 is provided, in which alternately teeth 52 and interdental spaces 54 equally spaced follow one another.
  • the teeth 52 are formed in plan view substantially as rectangular wedges.
  • two pins are provided as marking means 64, 66, with which a rotational position of the part diameter 50, based on its axis of rotation, can be determined.
  • Each of the dividing blades 40, 50 has a flat rear side and a front side, which is bevelled outwardly at least on the toothed rim 48, 58 in the radial direction. If the two dividers 40, 50 are placed with their backs against each other, the resulting circular blade 10 shows in side view a pointed central edge 60 (FIG. FIG. 1 ).
  • the cutting depth of the circular blade 10 can be changed by turning the dividing blades 40, 50 against each other, e.g. be rotated by a tooth width against each other.
  • the first dividing blade 40 has cutting edges at the free ends of the teeth 42, while the tooth bottoms 46 have no cutting edges.
  • the second knife 50 has cutting edges on both the free ends of the teeth 52 and the tooth bottoms 56.
  • the first dividing knife 40 has a larger circumference than the second dividing knife 50.
  • the cutting edges of the teeth 42, 52 may be tangent to the circumference or along the circumference of the indexer 40 curved. This avoids a pulling cut that can lead to material breakage or cracks.
  • the teeth 42, 52 may e.g. have a trapezoidal base.
  • the central opening 28 serves for fastening the circular blade 10 to a tool holder of a machine or a hand-held tool (not shown) with which the circular blade 10 is guided along a material to be processed, eg corrugated cardboard.
  • the circular blade 10 is rotatably drivable, so that it rolls along the surface of the material to be processed and thereby generates a perforation cut.
  • the cutting edges of the teeth 42, 52 and the tooth bottoms 46, 56 pierce the outer skin completely and an outer skin near region of the wavy intermediate layer, which outer skin and inner skin spaced, while the inner skin is pierced only by the cutting edges of the teeth 42, 52.
  • the widths of the teeth 42, 52 and the interdental spaces 44, 54 are approximately the same in this example. If necessary, these can also, depending on the desired sectional image and / or material to be cut, have different widths.
  • the two partial blades 40, 50 are rotated relative to one another such that the teeth 52 of the second partial blade 50 are arranged between the teeth 42 of the first partial blade 40.
  • the two dividing blades 40, 50 are further rotated by one tooth width, so that the tooth bottoms 56 of the second dividing blade 50 are arranged between the teeth 42 of the first dividing blade 40.
  • the rotational position of the two partial blades 40, 50 to one another can also be read from one another at the position of the marking means 62, 64, 66.
  • FIG. 4 shows the attachment of a perforation in a thin corrugated cardboard 100, such as an outer packaging, with the circular blade 10 from FIG. 1
  • FIG. 5 shows the attachment of a perforation in a thick corrugated cardboard 100 with the circular blade 10 from FIG. 1 with suitably twisted part blades 40, 50.
  • FIG. 4 It can be seen that for cutting a single or thin corrugated cardboard, the dividing blades 40, 50 are rotated in the circular blade 10 against each other so that the cutting edges are arranged on the teeth 52 of the indexer 50 in interdental spaces of the teeth 42 of the indexer 40, so that Distance of the cutting edges on the teeth 42, 52 is low.
  • the circular blade 10 when rolling over the outer skin 110 of the thin corrugated cardboard, the outer skin 110 with the teeth 42 of the first part diameter 40 and the teeth 52 of the second part diameter 50 completely and the intermediate layer 112 largely cut while the inner skin 120 is pierced only by the cutting edges on the teeth 42 of the first part diameter 42.
  • the marking means 64 of the second dividing blade 50 can be seen, wherein the marking means 62 covers the second marking means 66 of the second dividing blade 50.
  • FIG. 5 It can be seen that for cutting a two- or multi-ply or thick corrugated cardboard, the dividing blades 40, 50 are rotated in the circular blade 10 against each other so that the cutting edges are arranged on the tooth bottoms 56 of the dividing blade 50 in interdental spaces of the teeth 42 of the dividing blade 40, so that the distance of the cutting edges on the teeth 42, 52 is large.
  • the corrugated board has between outer skin 110 and inner skin 120 two intermediate layers 112, 116, which are separated by an intermediate skin 114.
  • the outer skin 110 and the first intermediate layer 112 and the intermediate skin 114 are completely severed by the cutting edges of the teeth 42 of the first indexer 40 and the cutting edges on the tooth bottoms 56 of the second indexer 50, while the inner skin 120 and the second intermediate layer 116 only from the cutting edges is pierced on the tooth bases 56 of the first indexer 50.
  • the marking means 66 of the second dividing knife 50 can be seen, wherein the marking means 62 covers the second marking means 64 of the second dividing knife 50.
