Description

The invention relates to a device for the rotary machining of material to be processed, wherein the processing may be, for example, a punching, embossing or punching, with in the machining about mutually parallel tool axes rotating tools, preferably a plurality of distributed over the respective circumference of a tool arranged tool-formations , such as punches or holes, further wherein the tools are held by means of rotating around the same tool axes, in an engagement region of tooth flanks synchronizing gears in predetermined circumferential alignment to each other and the tools for handling such as insertion of material to be processed and / or exchange of Tool formations are moved apart.

Devices of the type in question are known, for example in the form of rotary punching devices. In such punching applications, as well as embossing or perforations, a tool is preferably designed as a die and the other tool as a male. This requires working with as narrow as possible precisely guided kerf. In a known manner, for this purpose, the shafts driving the tools are coupled to one another via suitable systems such that the particularly punch-shaped tool formations dive exactly into the preferably hole-like tool formations of the other tool. Preferably find here synchronization gears with the least possible use.

It may be necessary to change the distance of the tool axes temporarily, for example, to introduce workpieces between the tools or replace one or both tools. This raises the problem that in the course of moving apart of the tools or the tool formations and the synchronization gears lose their engagement with each other, so that, if necessary, a new synchronization of the tools or the tool-formations is necessary.

In this connection known solutions, such as the EP 1419861 B1 , Provide a secondary synchronization, which maintains the synchronization of the tools in the extended position of the tool-formations and this associated disengagement of the synchronization gears. The secondary synchronization means are additionally provided and may comprise chain or toothed belts and wheels cooperating therewith.

In view of the known prior art, the invention has the object to provide a device for rotating machining of material to be processed, in which the synchronization of the tool-shaped formations is ensured as simple as possible constructively even in the extended position.

A possible solution of the problem is given according to a first inventive idea in a device in which is geared to that one of the tools relative to the other tool is pivotable about a pivot axis without the engagement of the synchronization gears is canceled each other, wherein the pivot axis of the Engaged intervention area or in the direction of the tool axis and / or perpendicular thereto - based on a theoretical center of the engagement area - by the 0.05-fold or is less of the distance between a middle plane of a tool formation, optionally one of the pivot axis closest center plane of a tool formation, and the theoretical center of an engagement portion is offset. The offset is also referred to as offset measure.

An engagement region typically travels along a tooth flank as the teeth of the synchronization gears roll. The above provision therefore refers in further detail to a position of the gears to each other, in which a vertical connecting line between the tool axes a tooth - based on the opposite tooth flanks - passes through the center. In another position of the gears to each other, the pivot axis may also differ from the above characterization.

As a rule, and preferably always two opposite engagement areas are given. In this case, as reference point and an axis through the theoretical center of these opposing engagement areas - in the position of the gears to each other as stated above - are used, which can be used as a reference point, the center of the axis between the engagement areas.

The theoretical center results from the geometric shapes of the tooth flanks and, in the above-mentioned position of the toothed wheels, one or two opposite geometric contact points resulting therefrom.

It is a device specified, which manages in particular in the retracted position of the tools or tool-formations without secondary synchronization means. Rather, the synchronization gears in operation during operation also serve in the disengaged position of the tools for maintaining synchronization. This is achieved by a pivotable arrangement of one of the two tools relative to the other tool. The in the machining position preferably parallel to each other extending tool axes - possibly in the usual tolerance frame diverging tool axes - extend in the extended position of the tools at an acute angle to each other.

Preferably takes in the extended position of the tools, viewed in a vertical plane with respect to a common use position of the non-pivoted tool axis, the tool axis an acute angle relative to the other tool axis of 0.1 to 3 °, more preferably 0.3 to 1 ° one.

By way of derogation and, where appropriate, as an alternative to the determination of the displaced dimension given initially, it is also possible to assume an absolute displaced dimension. The absolute displaced measure corresponds empirically found maximum 10 mm. This in turn, starting from the said course of the pivot axis by the geometric points of contact in the selected position of the gears to each other.

The engagement region of the synchronization gears can initially - at least theoretically - be given only point or line like. For example, by an extending transversely to a tool axis engagement line between the engaged flanks of teeth of the synchronization gears. In practice, the synchronization gears act on a certain width and / or height in the direction of the tool axis or perpendicular to each other. This results in the engagement area. The pivot axis can run within the engagement area, in any case with respect to a - as viewed from the tool axis - vertical projection on the engagement area, or outside of the engagement area.

The tools are preferably attached to (vertically) associated free-projecting ends of the tool axes. The storage is designed accordingly only on one side of the tools. But it is also possible that the (relative to the installed state) lower and / or upper tool is mounted on both sides.

The tools are accommodated in a preferred embodiment in a frame with a tool storage, wherein a first frame part with a first tool relative to a second frame part with a second tool is pivotable to achieve the pivotability of the two tools to each other. Advantageously, the pivoting of the first tool takes place together with its storage in the first frame part.

The frame parts may be a total of parts of a device housing. The second frame part can insofar also be the device housing or a substantial part of the device housing. In the latter case, the second frame part with the first frame part as a whole can complement the device housing. An embodiment is preferred in which the frame part which supports the first tool is arranged within the frame part which supports the second tool. The respective tool bearings, as well as the non-rotatably connected to this first tool synchronization gear remain correspondingly at a pivoting of the tool in its relative orientation and position to the first tool and the associated first frame part or in their relative orientation and position to the tool axis of the first tool.

The given to achieve the pivoting pivot axis forms in a preferred embodiment at the same time a bearing axis of the first frame part in the second frame part. The second frame part is preferably mounted on bearing axles, for example bearing journals, in corresponding bearing openings of the second frame part.

Alternatively, the pivot axis can be firmly connected to both frame parts and the pivoting result from a twisting of the pivot axis.

The first frame part, the first tool including the tool support and the synchronization gear rotatably mounted on a tool shaft form a structural unit which is relatively pivotable to the further assembly, which consists essentially of the second frame part, the second tool and its tool storage and composed on a (second) tool shaft rotatably arranged second synchronization gear.

In the machining state are the tool-shaped formations, so in particular a male and a die, for example a punch of a tool and a hole of the other tool, in engagement position to each other. It results in the direction of the first or second tool axis considered one each perpendicular to the respective tool axis extending center plane of the tool-formations of the tool in question. Normally, these levels coincide in the usual position of use of the tools.

Furthermore, in the processing state, i. in an engaged state of two associated tool moldings of the tools with respect to a tool molding, a preferably circumferential working gap, for example cutting gap, with a transverse to the dipping direction of a tool molding in the other tool molding gap width of 0.03 to 0.07 mm, preferably 0.05 mm. This is more preferable for a tool with a tool molding in the form of a round die with a diameter of 8 mm and a corresponding die in the form of a hole with a diameter of 8.1 mm. The immersion depth of a tool molding in the other tool molding is in a preferred embodiment 0.2 to 0.8 mm, in particular 0.5 mm. The immersion depth is in this case the measure that can be removed in a direction of extension of a middle plane, via which is perpendicular to the middle plane, the one tool molding within the other tool molding.

In the direction of the first or second tool, the pivot axis in the machining state is preferably arranged with such a distance to a middle plane of a tool, possibly to the middle plane of a tool closest to the pivot axis, that during a pivoting of the tool axes - preferably only one of the tool axes is pivotable - 1 ° to each other results in a displacement of the average planes of the first and second tool to each other from 0.01 to 0.05 mm. The corresponding lateral displacement of the tool molding of the tool to be lifted, in particular the lateral displacement of the punch relative to the die is smaller or at most equal to the given in the machining position width of the kerf, according to the proposed solution.

Thus, further preferably results in a lateral displacement of a punch in the die at an opening stroke of 0.5 mm (punch leaves the die) of preferably only 0.004 mm or preferably full opening or raising of a tool of 3 mm (0.5 mm Immersion depth plus material thickness of the material to be processed) a lateral deflection of 0.015 mm.

It results in an advantageous manner in the retracted position of the tools or in the pivoted position of a tool in a projection perpendicular to one of the tool axes a complete or almost complete projection image of the pivoted-tool shape, in particular of the punch, within the contour of the other tool -Eusformung, in particular of the hole or the die.

The distance of the pivot axis, viewed in the direction of the tool axis of the first or second tool, to a central plane of a tool corresponds in a preferred embodiment to 400 to 800 times, preferably approximately 600 times the immersion depth of one tool formation into the other tool space. Forming in the processing state. More preferably, the distance is 200 to 700 mm, wherein a first preferred range is 200 to 400 mm, in particular 300 mm.

As favorable, the arrangement of the pivot axis proves to be in the range of the synchronizing gears in engagement. Also, an arrangement of the pivot axis may be provided in which the pivot axis affects both pitch circles of the synchronization gears at the same time.

In a projection of the pivot axis onto a tool axis, in which projection the first tool axis overlaps the second tool axis and / or a perpendicular on the pivot axis, which intersects the first tool axis, forms a point in the projection plane, the pivot axis preferably extends substantially perpendicular to the tool axis of the first tool. Preferably, a strictly vertical orientation of the pivot axis relative to the tool axis as well as more preferably a strict alignment of the pivot axis within the projection plane. Also, the pivot axis to the perpendicular to the tool axis and / or to the projection plane may include an acute angle of preferably 0.001 to 3 °.

A tool is preferably rotatably mounted in the respective frame part between the pivot axis and the tool. Conventional rotary bearing designs are used here, more preferably over the axial length of the tool-carrying shaft a plurality of rotary bearings being provided, in particular two rotary bearings. For example, spherical or roller bearings are used as pivot bearings.

In particular, in the processing state, the tools are arranged one above the other in the frame, so that in a plane in which the tool axes are represented as points, the tool axes on a - based on a horizontal footprint of the device - common vertical are arranged.

In any case, one of the tools, but in principle both tools, can be rotationally driven. In particular, an electric drive is used here, which acts directly or indirectly on the tool or on a shaft carrying the tool. The other tool is rotatably driven via the synchronization gears indirectly via a tool. In this case, there are preferably opposite rotational movements of the tools.

The tools can also - only - be rotatable by the processed material to be processed itself. The material to be processed is, for example, pulled and thus turns the tools by towing. In this case, the drive can be effected via a positive connection of interlocking tool formations. But the drive can also - at least over part of the circumference of the cooperating tools - be effected via purely frictional engagement between the material to be processed and the tools. In particular, if, due to a large circumferential distance between cooperating Werkzeugausformungen the tools over at least a part of its turning circle are not in form-fitting engagement. For this purpose, the tools can also have on their circumference, for example by a rubber material, a special frictional engagement design.

The driven tool is preferably arranged in the fixed frame part and the non-driven tool in the opposite pivotable frame part. Accordingly, in a preferred embodiment, the for moving apart pivotable tool only indirectly via the synchronization gears driven tool.

The pivotable tool axis is preferably fixable in the machining position, in particular such that the predetermined immersion depth of the example punch-shaped tool molding of the first tool in the example punched tool molding of the second tool, as more preferably a predetermined kerf in the course of processing the material to be processed is maintained. The setting of the pivotable tool axis is preferably carried out according to mechanical loading of the corresponding tool receiving (first) frame part against a given example by the second frame part stop.

To fix the pivotable tool axis, a particular acting on the pivotable frame part fixing part may be provided, which moreover can also be used as preferred acting on the frame part means for pivoting the tool. The fixing part is preferably an electrically and / or hydraulically displaceable lever, which is in particular hingedly connected to the first frame part. Alternatively, the lever can also be adjusted by hand or, for example, by means of compressed air.

With regard to the disclosure, the ranges or value ranges or multiple ranges given above and below also include all intermediate values, in particular in 1/10 increments of the respective dimension, if necessary also dimensionless, in particular 1.01-fold, etc. on the one hand to delimit the mentioned Range limits from below and / or above, alternatively or additionally but also with regard to the disclosure of one or more singular values from the respectively specified range.

Shown and described is a device 1 for rotating machining, in particular for rotary punching of a strip-shaped processing material 2.

The apparatus 1 initially has a housing 3, not shown in detail, in which two tools 4 and 5 rotating during the processing state are received and stored.

The drive is effected via an electric motor 6, not further illustrated, of a drive unit 7. The drive unit 7 is preferably coupled to the housing 3.

The housing 3, in particular, overhangs two frame parts 8 and 9. Thus, a first frame part 8 is provided, which is held pivotably in a second frame part 9.

The frame part 9 is fixed, i. especially in the operation of the device 1 in its position and orientation can not be changed.

The frame part 9 in particular supports the tool 5.

The first frame part 8 pivotally mounted in the second frame part 9 supports in particular the tool 4.

The tools 4 and 5 are substantially formed as a drum-shaped tool carrier, wherein the tool 4 has a male part outside on the circumference uniformly distributed tool-shaped formations 10 in the form radially over a lateral surface of the drum freely projecting cutting punch.

The drum-shaped tool carrier of the second tool 5 has in the circumferential direction uniformly as the tool-shaped formations 10 of the tool 4 distributed tool-shaped moldings 11, in particular Form of holes. The tool 5 accordingly serves as a die for the tool 4.

In the illustrated embodiment, each tool 4 and 5 has two in the direction of the respective tool axis x and y spaced apart planes with tool-formations 10 and 11.

The tools 4 and 5 are each mounted on a tool shaft 12,13 in the associated frame part 8, 9. The tools 4 and 5 are rotatably connected to the tool shafts 12,13.

To accommodate the tool shafts 12,13 in the frame parts 8, 9 pivot bearing 14,15 are provided. This is in a preferred embodiment to ball or roller bearings.

The respective bearing is provided in particular in the region of one end of the tool shaft 12, 13 remote from the respective tool 4 or 5, while a further bearing spaced from the aforementioned rotary bearing is preferably formed close to the tool in the respective frame part 8 or 9.

The tool axes x and y extend at a distance from each other in parallel and in the machining position of the device 1 preferably one above the other in such a way that the tool axes x and y preferably extend within a vertical plane.

In this case, the tool 4 with the frame part 8 is furthermore preferably positioned above the tool 5.

The vertical distance between the tool axis x and y to each other is chosen so that, taking into account the tool diameter, a radial distance is adjusted to form a passage gap 16 for the processed material 2 (see FIG. 3 ).

The tool 5 mounted in the stationary frame part 9 is preferably driven directly by means of the drive unit 7, for which purpose the latter acts correspondingly rotationally on the tool shaft 13.

On the tool shafts 12 and 13 are further each a synchronization gear 17 and 18 arranged rotatably. These each extend in a region between the respective pivot bearings 14 and 15 and are in engagement with each other. Preferably, both synchronization gears 17 and 18 are the same design.

Via the synchronization gears 17 and 18 there is an indirect rotation of the upper tool 4, wherein further on the synchronization gears 17 and 18, the tools 4 and 5, in particular their tool-formations 10 and 11 are held to each other in a predetermined circumferential orientation.

In the in the FIGS. 1 to 3 illustrated machining position of the device 1, ie in the punching position shown here immersed in the course of rotation of the tools 4 and 5, a punch-shaped tool molding 10 preferably 0.5 mm in the Gegenausformung of the tool 5, this punching of the material to be processed 2 (see FIG. 3 ).

A patrix-side tool molding 10 is preferably formed in the form of a round die with 8 mm diameter. The hole-like die corresponding thereto has a diameter of 8.1 mm, so that a circumferentially uniform cutting gap of approximately 0.05 mm is preferably established circumferentially.

The frame part 8 and hereby the tool shaft 4 mounted on the tool 4 is pivotable about a pivot axis z relative to the frame part 9, which pivot axis z in a projection on a, the tool axis y of the lower tool 5 receiving horizontal plane - with respect to the operating state - perpendicular to the tool axis y and according to the axis parallelism also perpendicular to the tool axis x of the first tool 4 extends.

Viewed in the direction of the tool axes x, y, the teeth 17 'and 18' of the synchronization gears 17 and 18 act on one another at a width which can correspond to the thickness of the gears 17 and 18 in the area supporting the teeth 17 'and 18' , This results in an engagement region B in which an engagement of the tooth 18 'on the facing flanks of the teeth 17' of the toothed wheel 17 is achieved on opposite flanks 18 "of a tooth 18 'of the toothed wheel 18. A singular position, which also serves as a reference position is preferably used is given if a connecting line L between the tool axes x, y, standing perpendicular to this, a tooth 18 'passes through in the middle FIG. 7 shown.

The pivot axis z preferably extends through an engagement region B, according to which, albeit very small, deformations of the tooth flanks usually occupy a certain area.

With reference to FIG. 6 It can be seen that a substantially hemispherical offset region V can be given with a center point that can result from a theoretical center of an engagement region B, possibly a connection axis between two opposing engagement regions B, the center thereof. The radius of the offset region V in this example is preferably 0.01 times the below-described distance a or less, alternatively at most 2 mm. Within this offset range V can therefore be the pivot axis z, perpendicular to the plane in FIG. 6 , extend. The offset region V preferably extends from a theoretical course of the pivot axis z through said theoretical centers of the engagement regions in a singular position of the gear wheels relative to each other FIG. 7 only above and below and on the side facing away from the tool side of the theoretical pivot axis. Due to a generally given gap S between the meshing tooth of the one gear and a tooth base between two opposing teeth of the other gear, seen in the direction of the connecting line L, but also a displacement in the direction of the tool is not completely excluded. Basically so far until the tool would come due to a consumption of the gap S and in view of the pivoting angle to a collision of the gears.

The above determination of the offset range V is equally valid for the said absolute offset measure, so that a radius with respect to the offset range V results in the size of the said absolute offset measure.

The pivot axis z is below, as can be seen, based on the illustration in FIG. 6 in which the tool axes x, y map as lines and the plane of the drawing of both tool axes x, y passes through, arranged in height between these tool axes, in a central region.

Each tool formation 10 and 11 forms a longitudinal plane of the respective tool axis x or y considered average plane E and E '(see FIG. 3 respectively FIG. 5 ). These levels E and E 'fall in the processing state as shown in FIG FIG. 3 preferably together.

The distance a of the pivot axis z to the middle plane E, in particular of the tool formation 10 of the liftable or swivellable tool 4, may amount to, for example, 300 mm in the case of a preferably parallel measurement to the tool axis x.

The pivotal mounting of the frame part 8 in the frame part 9 is preferably given by a pin arrangement, which pins engage in corresponding bearing holes. Alternatively, a pivoting result from a twisting of the pivot axis.

The machining position according to the Figures 2 and 3 is defined in particular according to a stop limit 22 of the pivotable frame part 8 in the direction of the machining position.

For example, for the introduction of material to be processed 2 and / or replacement of tools or tooling molds tools 4 and 5 are moved apart, so preferably by pivoting the frame part 8 and thus lifting and lifting the tool 4 from the tool. 5

The raising and lowering of the frame part 8 and thus also of the tool 4 is preferably carried out via a lever mechanism 19. This is preferably an electromotively and / or hydraulically or pneumatically displaceable plunger 20, which acts on a hinged arm 21. The tappet 20 facing away from the end portion of the handlebar 21 in turn acts on a portion of the pivotally movable frame part eighth

In the machining position according to FIG. 2 the handlebar 21 acts in the manner of a hold-down for fixing the machining position.

By appropriate activation of the lever mechanism 19, the frame part 8 is pivoted about the pivot axis z, in this example, preferably only by 0.5 to 2 °, more preferably about 1 °.

In this pivoting position of the frame part 8 and the tool 4, the stamp-like tool molding 10 is in the example compared to the machining position according to FIG. 3 about 3 mm (compare dimension b in FIG. 5 ), which opening dimension b of the penetration depth of the punch into the die as shown in FIG FIG. 3 plus the material thickness of the material to be processed 2 substantially corresponds.

In this open position is a lateral deflection of the punch-shaped tool molding 10, ie viewed in the direction of the tool axis x and y displacement of the relevant plane E with respect to the plane E 'given the die-side tool molding 11, which is preferably selected with 0.015 mm smaller as the theoretically required in this example in the processing state circumferential cutting gap.

Advantageously, remain in the pivoted position shown in Figures 4 and 5, the teeth of the synchronization gears 17 and 18 in their synchronizing engagement position, so that even in the raised position, the tools 4 and 5 remain in their synchronous alignment.
