Definitions
- the invention relates to a separating device for processing sandwich panels with a motor-driven cutting tool which can be moved in the cutting direction relative to the sandwich panel to be processed and which has cutting elements guided by means of a guide device in a plane of movement running transversely to the plane of the panel.
- Sandwich panels are multi-layer workpieces with inconsistent mechanical strength in the individual workpiece layers. They usually consist of a foam core as well as this on both sides adjacent top layers in the form of thin metal sheets. Sandwich panels typically have a thickness of 40 to 200 millimeters, the thickness of the metal sheets, mostly steel sheets, is approximately 1 millimeter.
- a generic device for processing sandwich panels is described in US-A-4,984,615.
- the cutting tool of the known device comprises a plurality of cutting elements arranged one behind the other in the cutting direction and guided in a straight line in this direction in the form of cutting knives.
- Cutting knives leading in the cutting direction run obliquely to the plate plane and are inclined in a V-shape with respect to one another.
- a cutting knife lagging the mutually inclined cutting knives is oriented in the cutting direction and perpendicular to the plate plane.
- a material strip is cut out of the cover layer of the sandwich panel, which has a relatively high mechanical strength, and thereby the core of the sandwich panel is cut free. Then the relatively soft core of the sandwich panel is cut by means of the cutting knife running perpendicular to the plane of the panel.
- the known separating device allows processing of sandwich panels only starting from the free edge of the panel.
- the present invention has set itself the goal of expanding the possibilities for separating processing of sandwich panels with at least constant quality of the cut surfaces created, starting from the described prior art.
- this object is achieved in that, in the case of a separating device of the type mentioned at the outset, a cutting chain with cutting elements in the form of chain links and a chain guide is provided as a guiding device, the chain links lying one behind the other in their direction of movement relative to one another transversely to their plane of movement Swivel axes can be pivoted and are guided in the plane of movement partly in a straight line, partly under an arcuate deflection and each have a plurality of cutting teeth lying one behind the other in their direction of movement, which protrude on the cutting chain in the radial direction and are provided with cutting edges which are in the transverse direction of the plane of movement of the chain links extend, the vertical projections of the cutting edges in the plane of movement being arranged at least partially along a radially outwardly curved arc line.
- the separating device is able to process sandwich plates either from their free edges or from any points in the plate surface.
- the area of the cutting chain in which the chain links are deflected in an arc shape can be inserted into the sandwich panel to be processed. If the cutting chain is in engagement with the area of the linear guidance of the chain links, then a flat cut front which delimits this in the cutting direction results at the created cutting slot.
- Such flat cut fronts require a straight line of the apex line of the cutout corner where two separating slots meet, that is to say in corners of cutouts on the sandwich panel in question.
- the design of the cutting teeth according to the invention ensures that the different materials of a sandwich panel can be cut by means of the separating device without interlocking, from which the quality of the cutting result would suffer.
- the feature according to the invention also serves to achieve a high-quality cutting result, according to which the vertical projections of the cutting edges into the plane of movement are at least partially arranged along a radially outwardly curved arc line.
- the cutting chain has three adjacent rows of chain links, the chain links of the two outer rows forming outer links and the chain links of the intermediate row forming central links, and wherein the adjacent outer links are aligned with one another and the central links are staggered in the direction of movement of the chain links against the outer links and with them Outer members lying one behind the other overlap and / or that the cutting edges of at least the outer links lying next to one another are flush with one another and / or that
- the outer surfaces of the chain or outer links are flat and / or that
- At least one of the outer surfaces of the chain or outer links extends to form a clearance angle with respect to the respectively assigned cut surface on the sandwich plate and / or that
- the chain links each have at least five cutting teeth and / or that
- the cutting edges of at least a part of the center links on the cutting chain protrude radially with respect to the cutting edges of the outer links and / or that
- the space which necessarily remains between the cutting teeth adjacent to one another in the direction of movement of two outer links which follow one another in the direction mentioned can be determined by means of the space at the level of the space mentioned. orderly cutting teeth of the center link of the cutting chain overlapping with the relevant outer links are closed. As a result, seen in the direction of movement of the chain links, there is a dense succession of cutting teeth or cutting edges.
- the planar design of the outer surfaces of the chain or outer links serves for precise guidance, for example free of undesired vibrations, on the cut surfaces of the sandwich panel to be processed in the cutting direction.
- the clearance angle between the outer surfaces of the chain or outer links of the cutting chain and the cutting surface on the sandwich plate opposite the surfaces mentioned prevents the cutting chain from jamming on the sandwich plate.
- the above-described variation of the spacing of the cutting edges of adjacent cutting teeth on a chain link causes the cutting chain to run smoothly and with little wear and allows high cutting and processing speeds with excellent quality of the cut surfaces created.
- the adjacent outer and center links are connected to one another for the sake of simplicity via connecting bolts, the axes of which form the pivot axes about which the chain links lying one behind the other in their direction of movement are relative to one another are pivotable.
- the connecting bolts mentioned are preferably radially expanded in their axial sections assigned to the center links to form a collar.
- the cutting chain is at least partially enclosed on the drive side by a housing, an intermediate space which can be connected to a suction device being formed between the cutting chain and the inner wall of the housing.
- a machine guide is provided, by means of which a base body of the separating device, provided with the cutting chain, for guiding the sandwich panel in question, in particular when piercing the sandwich panel, can be moved relative to the latter.
- the machine guide comprises a support which can be supported on the sandwich panel to be machined and on which the base body of the separating device is mounted so as to be movable relative to the sandwich panel.
- a simple kinematics of the relative movement of the base body of the separating device with respect to the sandwich plate distinguishes a variant of the separating device according to the invention, in which the base body of the separating device is pivotally mounted on the support about an axis running parallel to the plate plane.
- a further embodiment of the invention is characterized in that the base body of the separating device can be moved or pivoted from the rest position into a working position by means of the machine guide against the action of a restoring force. Under the effect of the restoring force, the basic body of the separating device and with it the cutting chain automatically move into a position in which the cutting chain is out of engagement with the sandwich plate in question.
- a preferred embodiment of the invention provides that the basic body of the separating device in the working position with different positions, possibly with different pivoting positions, of the cutting chain or the chain guide can be locked relative to the relevant sandwich panel, preferably locked. A set, appropriate relative position of the cutting chain or chain guide and sandwich plate is maintained in this way without the intervention of the device operator.
- a support plate is provided as a structurally simple design and at the same time functional support of the machine guide, which has a slot for the cutting chain moved relative to the sandwich plate and the chain guide.
- the present invention also relates to a cutting chain for such a separating device.
- the cutting chain according to the invention has chain links as described in claim 19.

At both ends of the guide rail 4, the cutting chain 5 is deflected along an arcuate path, on the long sides of the guide rail 4, the cutting chain 5 guided in a straight line.
- An electric motor 6 with two speed switching stages is used to drive the cutting chain 5.
- the base body 3 of the separating device 1 On its side opposite the electric motor 6, the base body 3 of the separating device 1 is provided with a housing 7 broken open in FIG. which encloses the cutting chain 5 on the drive side, forming an intermediate space 8 between the cutting chain 5 and the housing 7. In the space 8 opens a suction hose 9, which is attached to the latter via a connecting piece 10 of the housing 7 and is connected at its other end to a suction fan.
- a machine guide 11 of the separating device 1 essentially consists of a support plate 12 and a pivot bearing 13, by means of which the base body 3 of the separating device 1 is pivotally connected to the support plate 12 about an axis 14 running parallel to the plate plane of the sandwich plate 2.
- a double arrow 15 illustrates the direction of the relative pivoting movement of base body 3 and support plate 12.
- a slot 16 in the support plate 12 allows the base body 3 of the separating device 1 and with it the cutting chain 5 between the working position according to FIG. 1 and a rest position, in which the cutting chain 5 is out of engagement with the sandwich plate 2, back and forth swing.
- the operator of the separating device 1 has handles 17, 18 on the base body 3.
- an elastic counterforce has to be overcome, which is deformed by one when the relevant pivoting movement is carried out and not in individual torsion spring shown the pivot bearing 13 is applied.
- a latching device 19 is used for this purpose. It comprises a plurality of latching openings on the base body 3 of the separating device 1 and a latching pin 20 which can be moved in the axial direction against spring force and which is held displaceably in its axial direction on a bearing block 21 connected to the support plate 12 of the pivot bearing 13 is.
- the latching openings are located on the side of the base body 3 facing away from the viewer of FIG. 1 and are arranged one behind the other in the direction of the pivoting movement of the base body 3.
- the operator of the separating device 1 engages the lockable locking pin 20 in one of the locking openings.
- the base body 3 was counterclockwise when the electric motor 6 was switched on, from a rest position in which the cutting chain 5 and the chain guide 4 were located on the side of the support plate 12 facing away from the sandwich plate 2 the axis 14 has been pivoted.
- the cutting chain 5 had come to rest through the slot 16 of the support plate 12 on the surface of the sandwich plate 2.
- the cutting chain 5 had cut into the sandwich plate 2 until it was finally inclined against the sandwich plate 2 with the guide rail 4 at the end of the pivoting movement, as shown in FIG.
- the separating device 1 had been slid by the operator in the cutting direction, namely in the direction of an arrow 22, on the sandwich plate 2 and in this way a separating slot had been created in the sandwich plate 2, which slot had its exit inside the surface of the sandwich plate 2 .
- the cutting chain 5 had revolved in the direction of movement illustrated by an arrow 23.
- the cutting chain 5 had cut through the different layers of the sandwich plate 2. The cutting dust formed in this way was sucked into the space 8 between the cutting chain 5 and the housing 7 and was discharged from there via the suction hose 9.
- the support plate 12 served to protect the operator from the rotating cutting chain 5.
- FIG. 1 Another possibility for processing the sandwich panel 2 with the separating device 1 is shown in FIG.
- the separating device 1 with the support plate 12 with the guide pointing downwards perpendicularly to the sandwich plate 2 was tion rail 4 for the cutting chain 5 placed on the sandwich plate 2 and then, starting from the free edge of the sandwich plate 2, a separation slot, inter alia, delimited by a cutting surface 24, has been created. Since the cutting chain 5 was in engagement with the sandwich plate 2 with its region which was guided in a straight line on the guide rail 4, a flat surface was obtained as the front surface delimiting the separating slot in the cutting direction.
- the creation of the first separating slot was followed by the creation of a second separating slot which, starting from the free edge of the sandwich panel 2, ran parallel to the first separating slot.
- the separating device was then rotated through 90 ° about an axis running perpendicular to the plane of the sandwich plate 2 and, with the cutting chain 5 at rest, placed between the inner ends of the separating slots previously created. Subsequently, the cutting chain 5 cut into the sandwich plate 2 while pivoting the base body 3 of the separating device 1 accordingly.
- the separating device 1 was moved parallel to the free edge of the sandwich plate 2, starting from the recess that was created, and thereby cut a separating slot running perpendicular to the two initially created separating slots.
- a cut surface 25 formed one of the boundary surfaces of the last-created separating slot which runs in the cutting direction. Even the front surface this separation slot was straightforward.
- cut-out corners with rectilinear apex lines were obtained at the points where the mutually transverse separating slots meet, of which a apex line 26 is visible in FIG.
- the cut surfaces 24, 25 created, as well as the cut surface 24 that is not recognizable in FIG. 2 and opposite the cut surface 24, and the cut surface 25 run perpendicular to one another and perpendicular to the plane of the sandwich plate 2.
- the cutting chain 5 comprises three adjacent rows of chain links 27, 28, 29.
- the chain links 27, 29 form structurally identical outer links, the chain links 28 central links of the cutting chain 5.

- Each center link 28 overlaps with two outer links 27, 29 of the two outer chain link rows, one behind the other in the direction of movement 23.
- the connection between the chain links 27, 28, 29 is established by means of connecting bolts 30.
- each connecting bolt 30 passes through two adjacent outer links 27, 29 and the central link 28 located between them Axial sections assigned to center members 28, the connecting bolts 30 are radially expanded to form a collar 31.
- the dash-dot line in FIG. 5 indicates the center plane of the guide rail 4, which defines the course of the parallel movement planes of the chain links 27, 28, 29 of the chain link rows or the cutting chain 5.
- External surfaces 32, 33 of the outer links 27, 29 are flat.
- the axial end faces of the connecting bolts 30 are aligned with the faces 32, 33 of the outer links 27, 29.
- the connecting bolts 30 form the pivot axes about which the chain links 27, 28, 29 lying one behind the other in their direction of movement 23 can be pivoted relative to one another.
- Cutting teeth 34 in the form of saw teeth protrude on the chain links 27, 28, 29 in the radial direction and are provided with cutting edges 35 which run in the transverse direction of the planes of motion of the chain links 27, 28, 29 and each extend over the entire width of the chain links 27 , 28, 29 extend.
- the cutting edges 35 of the center links 28 protrude on the cutting chain 5 in relation to the cutting edges 35 of the outer links 27, 29 in the radial direction by approximately 0.7 mm.

- the distances between the cutting edges 35 adjacent to one another along the curved lines 36, 37 vary, as does the depth of the tooth gaps between the cutting teeth 34 in question.
- the arrangement of the cutting edges 35 on the outer links 27, 29 and on the center links 28 along the curved lines 36, 37 means that the cutting edges 35 on the outer links 27, 29 also describe one and the same movement path in the region of the deflection of the cutting chain 5 like the cutting edges 35 of the central members 28.
- the movement paths of the cutting edges 35 on the outer and on the central members are illustrated in dashed lines in FIG. 4 and provided with the reference symbols 38, 39. They run concentrically with a curvature which corresponds to the concurrent curvatures of the arc lines 36, 37.
