Definitions
- the invention relates to a scoring tool for a circular saw machine, in particular for a sliding table saw according to the preamble of claim 1, and a scoring saw blade therefor.
- Such a scoring tool is used in particular when a material with a sensitive or brittle cover layer is to be cut by means of a circular saw blade.
- the saw teeth of the circular saw blade can emerge from the workpiece cover layer at a relatively flat angle, as a result of which chipping or tears occur at the blade outlet on the cover layer.
- a scribing tool is therefore connected upstream when cutting (formatting) material panels coated in particular on both sides with format circular saws, which runs in the opposite direction to the circular saw blade.
- the scoring tool cuts through the lower cover layer, which is in danger of being broken out, and creates a scoring groove of shallow depth, into which the circular saw blade separating the workpiece then runs out when the separating cut is carried out.
- the center axes of the two tools In order for a straight, break-free edge to be created in the material plate on the discharge side of the circular saw blade, the center axes of the two tools must lie on a straight line and their cutting widths must be coordinated with one another. Sliding table saws are also used to cut materials with edges that are not prone to chipping.
- the scoring tool is swiveled away and only worked with the circular saw blade.
- the circular saw blade is generally subject to greater wear and must be resharpened earlier, but the cutting width of the circular saw blade changes and the resulting dimensional difference must be compensated for by adjusting the cutting width of the scoring tool.
- scribing tools used on sliding table saws consist of two partial blades and spacer rings arranged between them, the partial blades forming the scoring saw blade and being clamped between two flanges on a drive shaft.
- the cutting width of the scoring tool is adapted to the current cutting width of the circular saw blade by removing or adding one or more spacer rings.
- the cutting width of the re-sharpened circular saw blade is first measured; the scoring tool is then removed from the drive shaft, dismantled and a necessary number of spacer rings arranged.
- the sub-blades of the scoring tool are then axially fixed to the drive shaft in a rotationally fixed manner.
- a circular saw blade with an adjustable cutting width is known from EP-A-0 273 200, in which the partial blades are each fixed on a tool flange.
- the tool flanges have the same rotational symmetry and are axially adjustable with respect to one another by means of an external adjusting device, whereby the cutting width of the circular saw blade can be changed.
- the overall arrangement is very large, in particular due to the external adjusting device, which is why it can only be used to a limited extent as a scoring tool in the narrow space conditions on a sliding table saw.
- the invention has for its object to develop a scoring tool of the generic type such that an adjusting device for quick and easy adjustment of the cutting width to a downstream circular saw blade with little work is possible with a small overall size and specify a scoring saw blade for such a scoring tool.
- a scoring saw blade for use in such a scoring tool is shown in claim 11.
- the first tool flange of the scribing tool is axially displaceable relative to the second tool flange, e.g. B. guided telescopically, wherein the two tool flanges are axially and also in the direction of rotation positively and non-positively connected via the adjusting device arranged in the tool holder.
- the axial distance between the two tool flanges is changed by actuating the adjusting device. This preferably infinitely variable adjustment can take place during the entire service life of the scribing tool mounted on the drive shaft, so that time-consuming disassembly and assembly work is eliminated.
- the central axes of the fastening means lie on a common circle around the axis of rotation of the scribing tool, at least the central Axis of a fastener is arranged at a different distance from the central axes of adjacent fasteners.
- the adjusting device is a threaded spindle.
- the adjustment stroke desired as a function of the revolutions of the threaded spindle can be predefined in a simple manner via the thread pitch, so that a sensitive and infinitely variable adjustment is possible.
- the threaded spindle is expediently a screw bolt which projects through a non-threaded bore of the second tool flange in the direction of the first tool flange, the bolt head being axially supported on the second tool flange.
- the first tool flange is held axially displaceably on a hub of the second tool flange, the hub preferably engaging with a rotary driver in the displaceably held first tool half.
- the scoring saw blade for use in a scoring tool according to the invention of a circular saw machine consists of two partial blades, each partial blade having openings distributed through the circumference for the passage of fastening means, with which each partial blade can be fixed on a tool flange and the axially adjustable tool flanges via one Adjusting device are connected to one another.
- at least one passage opening is arranged offset over the circumference in the scoring saw blade or its partial blades, in relation to the other passage openings of the same partial blade.
- the location is the Passage opening arranged asymmetrically to the axis of rotation of the scoring saw blade is selected according to the balancing criteria of the scoring tool for which the scoring saw blade is intended.
- the partial blades of the scoring saw blade have an imbalance due to the asymmetrical arrangement of the through openings; this specifically created imbalance serves as a balancing weight for the tool holder of the scribing tool and compensates for the imbalance created by the inner adjusting device.
- the scoring tool itself is balanced.
- the through openings which are distributed unevenly over the circumference, furthermore ensure that the - unbalanced - scoring saw blade can only be used together with the corresponding - unbalanced - tool carrier, which must have corresponding bores for receiving the fastening means.
- a passage opening preferably has a countersink on the side facing away from the carrying tool flange for receiving the head of a fastening means, the countersink being at least slightly larger than is necessary for completely receiving the head. In this way, an unbalancing material removal is created, which is used for balancing the entire tool.
- FIG. 1 is a schematic representation of a circular saw machine with a scoring tool
- FIG. 2 shows a schematic plan view of a circular saw machine according to FIG. 1
- Fig. 3 shows a section through an inventive
- Scoring tool consisting of a tool carrier and a scoring saw blade
- FIG. 4 is a view of the scoring tool according to arrow Y in FIG. 3,
- FIG. 5 shows a view of the inside of a tool flange with a partial sheet fastened thereon according to arrow Y in FIG. 3,
- FIG. 7 shows a view of a partial blade of the scoring saw blade.
- FIG. 1 schematically shows a circular saw machine constructed as a sliding table saw with a circular saw blade K and a scoring tool 3.
- the clippings e.g. B. a bilaterally coated material plate W is fed in the direction of arrow P of the circular saw machine, the scoring saw blade 10 of the z. B. arranged below the plate W scribing tool 3, the plate W, that is, cuts into the plate W, but this does not cut.
- the circular saw blade K is arranged, which lies below the plate W in a plane E (FIG. 2) with the scoring saw blade 10.
- the circular saw blade K runs exactly in the scoring groove R machined by the scoring saw blade 10, so that an outbreak-free, straight cutting edge W is ensured on the outlet side K 'of the circular saw blade K separating the material plate W.
- the direction of rotation DR of the leading scoring tool 3 is opposite to the direction of rotation DK of the circular saw blade K.
- the cutting width SR of the scoring saw blade 10 is adapted to the cutting width SK of the circular saw blade K, preferably slightly larger than the cutting width SK of the circular saw blade K. This ensures that the circular saw blade K runs out in the scoring groove R during the cut without cutting in it.
- the scoring saw blade 10 When changing the circular saw blade K, z. B. due to a different material of the clippings or on a new blade, the scoring saw blade 10 must be set to the current cutting width SK of the circular saw blade K.
- the scoring tool 3 is designed in accordance with the structure shown in FIG. 3.
- the scoring tool 3 essentially consists of two tool flanges 1 and 2, which together form a tool holder 36. Each approximately half of the tool flange 36 representing tool flange 1 and 2 carries an annular partial blade 11 or 12, which together form a scoring saw blade 10. From the view according to FIG. 4 it can be seen that the teeth of one partial blade 11 lie in the gaps between the teeth of the other partial blade 12 in the direction of rotation.
- the first tool flange 1 is held axially displaceably on a hub 4, which is part of the second tool flange 2.
- the tool flange 2 and the hub 4 are separate components which are firmly connected to one another, preferably via screws 5.
- the hub 4 has at its one axial end an annular flange 6 which rests on an outer end face 7 of the annular second tool flange 2 facing away from the first tool flange 1.
- the hub 4 projects through the second tool flange 2.
- the ring flange 6 is preferably in one over the largest part of its thickness d Countersink 8, which is formed in the radially inner region of the outer end face 7 of the second tool flange 2.
- the screws 5 are arranged which engage in threaded bores 9 of the second tool flange 2.
- the screws 5 or their associated threaded bores 9 are preferably evenly distributed over the circumference of the rotationally symmetrical second tool flange 2; In the exemplary embodiment shown, four screws 5 or threaded bores 9 are arranged around the circumference at equidistant distances from one another on a common circle 16.
- the threaded spindle 20 preferably designed as a threaded bolt or screw spindle, lies parallel to the axis of rotation 33 of the scribing tool 3 and protrudes through a threadless axial bore 13 which is made in the second tool flange 2.
- the bore axis 14 (FIG. 5) lies below the inner edge 15 of the partial sheet 12 carried by the second tool flange 2 on its inner end face.
- the central axis 14 of the bore 13 may be expedient to arrange the central axis 14 of the bore 13 approximately on the common circle 16 on which the Central axes 17 of the screws 5 and the threaded bores 9 lie.
- the bore 13 is closer to the hub 4 than to the outer circumference 18 of the second tool flange 2.
- the head 21 of the threaded spindle 20 lies essentially completely in a countersink 23, on the bottom 22 of which the annular surface of the head 21 facing it lies.
- the depth t of the countersink 23 is equal to that Height h of head 21; the depth t is preferably slightly greater, so that the head 21 is held axially essentially free of play but rotatably between the second tool flange 2 and the annular flange 6 of the hub 4 forming a cover plate.
- the threaded spindle 20 projects through the thread-free bore 13 in the direction of the first tool flange 1 and engages in a threaded bore 19 which acts as an axial through-bore in the first tool flange
- a receptacle 25 is provided for engaging a tool such as a key or the like, so that the threaded spindle 20 can be easily rotated with the tool.
- the base body of the first tool flange 1 is - like the base body of the second tool flange 2 - essentially rotationally symmetrical and has an outer circumference 30 which forms a common surface of revolution with the outer circumference 18 of the second tool flange 2.
- the first tool flange 1 has an inner, cylindrical receptacle 31, in which the hub engages in an essentially play-free and displaceable manner.
- the axial length L of the hub 4 is longer than the axial length 1 of the inner, sleeve-shaped receptacle 31. The distance a between the tool flanges 1 and 2 and thus the cutting width SR of the scoring saw blade 10 can be adjusted by axial displacement on the hub 4.
- the receptacle 31 of the first tool flange 1 is axially extended by an inner sleeve extension 32 which engages with radial play in the annular, second tool flange 2 and - approximately at the distance a - ends in front of the ring flange 6.
- the hub 4 carries a rotary driver 26, which is in a axial coupling groove 27 of the inner receptacle 31 of the first tool flange 1 engages.
- the coupling groove 27 advantageously extends axially over the entire length of the receptacle 31 and is open on the two end faces of the first tool flange 1.
- the rotary driver 26 is preferably a part of axially limited length protruding radially beyond the outer circumference of the hub 4, which is designed according to the loads to be expected.
- the rotary driver 26 can be a component which is separate from the hub 4 and the first tool flange 1 and which can be inserted captively into the outer circumference of the hub 4.
- the tool flanges 1 and 2 each carry a partial blade 11 or 12 of the scoring saw blade 10.
- the partial blades 11 and 12 are designed as ring blades, which have countersinks 28 and 29, which are open radially outward, in the facing end faces of the tool halves 1 and 2 are inserted.
- the depth of the countersink 28 or 29 preferably corresponds approximately to the thickness b of a partial sheet 11 or 12.
- Each sheet 11 and 12 is fastened with fasteners on the respective tool flange 1 and 2 in a rotationally fixed and axially captive, but exchangeable.
- threaded screws 40 to 43 or 50 to 53 are provided as fastening means, which engage in threaded bores 44 and 54 (FIG. 3) of the tool flanges 1 and 2, respectively.
- the arrangement of the threaded spindle 20 forming the adjusting device 35 results in an uneven mass distribution over the circumference of the tool carrier 36, which is why the scoring tool 3 consisting of the tool carrier 36 and scoring saw blade 10 is considered
- the overall arrangement must be balanced. According to the invention, this necessary balancing is carried out by a Balancing criteria selected position of the fasteners of the sub-blades 11 and 12 achieved over the circumference of the scoring tool 3 with constructive means.
- the fastening means provided for fastening on the tool flange 2 are screws 40 to 43 which, as shown in FIG. 3, engage in threaded bores 44 in the tool flange 2.
- the threaded bores 44 or the through openings 70 to 73 provided in the partial sheet 12 have central axes 80 to 83 lying parallel to the axis of rotation 33 and are preferably distributed over the circumference on a common circle 45.
- the central axes 80 to 82 of the fastening means lie in the circumferential direction with an equidistant distance m from one another (FIG.
- the threaded bore 44 is longer than the screw 43. Since the partial sheet 12 is fixed over the circumference with several, preferably four screws 40 to 43 on the tool flange 2, four threaded bores 44 are formed over the circumference of the tool flange 2, which are only partially filled by the respective screw 40 to 43. However, this means that the remaining removal of material from the threaded bore 44 at the location of the screw 43 (FIG. 5) results from the adjustment device 35. Calling material accumulation can compensate if the threaded bore 44 of the screw 43 is at different distances ml and m2 (Fig. 7) to the adjacent threaded bores 44 of the screws 40 and 42 (Fig. 5).
- the threaded bores 44 of the fastening means which are arranged asymmetrically to the axis of rotation 33 according to the invention, thus bring about a balancing of the tool carrier 36 itself.
- a further contribution to the balancing of the scoring tool 3, i.e. the overall arrangement of the tool carrier 36 and scoring saw blade 10, is made by the through openings 70 to 73 of the partial sheets 11 and 12 (FIG. 7), which are distributed asymmetrically over the circumference 33 and which are congruent to the Threaded holes 44 are in the tool flange 1 or 2.
- the screws have a countersunk head 49 which lies in a countersink 77 in the through opening 73.
- the countersunk head 49 only partially fills the countersink 77; so z. B. a free space 78, which can correspond to a material removal necessary for balancing.
- Each sub-blade 11 and 12 thus contributes to the further balancing of the overall arrangement of scoring saw blade 10 and tool carrier 36.
- one or more through openings can have a shape that deviates from the circular shape.
- a kidney-shaped or elliptical shape is shown in broken lines using the example of the passage opening 73 in FIG. 7.
- a slit-shaped opening can also be expedient, as shown in dashed lines in FIG. 7 at the location of the opening 70.
- Bayonet-like configurations of the opening are also possible, as is sketched at the opening 72.
- the radial slot introduced into the edge of the opening 72 can have a suitable length, width and position and in particular extend over the entire axial length of the through opening.
- the scoring tool 3 which is balanced by a selected, asymmetrical arrangement of the fastening means for the partial blades 11 and 12, is pushed with the sleeve-like hub 4 onto a drive shaft and clamped axially.
- the axial bracing takes place exclusively between the end faces of the hub 4, as a result of which the second tool flange 2 is held axially in a machine-fixed manner, while the first tool flange 1 remains axially displaceable on the hub 4.
- the hub 4 therefore preferably protrudes slightly from the first tool flange 1 at maximum distance a, that is to say at maximum cutting width SR (FIG. 3).
- the threaded spindle 20 is rotated by the engagement of a tool in the externally accessible receptacle 25 of the threaded spindle.
- the maximum possible cutting width SR is shown.
- a locking screw 38 which is screwed radially into the first tool flange 1 is tightened, which acts on the rotary driver 26 of the hub 4 and causes radial clamping for axially fixing the tool flange 1 on the hub 4.
- the securing screw 38 is provided as an additional securing means; if the thread of the threaded spindle 20 is chosen to be relatively flat, additional securing is basically unnecessary.
- the threaded spindle 20 lies in a threadless bore 13 of the second tool flange 2; it may be expedient to design the bore 13 as a threaded bore and the threaded spindle on one half with a right-hand thread and on the other Half with a left-hand thread.
- the thread pitch can be chosen to be very flat, so that a sensitive adjusting device 35 is formed which is insensitive to axial forces.
- the fastening means (screw 43, 53), which is arranged asymmetrically over the circumference to the other fastening means, is preferably adjacent to the adjusting device 35 or its threaded bolt 20. It may be advantageous to further balance the overall arrangement by means of the screws 40 to 43, 50 to 53 receiving threaded holes 44, 54 with different excess lengths. The excess lengths can be dimensioned according to the material removal required for balancing at the location of the fastening means. In the case of a symmetrical arrangement of the fastening means, it may be sufficient to achieve a balancing of the overall arrangement solely by designing the excessively long threaded bores.
