Description

Lamellar block for a calibration device with internal bar

The invention relates to a lamellar block for a calibration device for calibrating an extruded profile. The invention also relates to a calibration device comprising a plurality of lamella blocks and a

Method for manufacturing a lamellar block, a system for additive manufacturing of such a lamellar block and a corresponding computer program and data set.

Calibration devices are used to calibrate extruded endless profiles, such as tubular profiles. In the production of such profiles, a plastic melt desired for producing the profile is first produced in an extruder. The plastic melt produced is then pressed through an outlet nozzle of the extruder, which defines the shape of the profile. The profile emerging from the outlet nozzle of the extruder then passes through a calibration device which reshapes the profile, which is still heated, with dimensional accuracy.

Such a calibration device for dimensioning extruded profiles is known from DE 198 43 340 C2. A variably adjustable calibration device is taught therein, which is designed for the calibration of extruded plastic pipes with different pipe diameters. The calibration device comprises a housing and a plurality of lamellar blocks arranged in a circle in the housing, which together form a calibration basket with a circular calibration opening through which the pipes to be calibrated are guided (see in particular Figures 1 and 2 of DE 198 43 340 C2). Furthermore, each lamella block is coupled to an actuating device which is provided for the individual radial displacement of the respective lamella block. In this way, the effective cross-section of the circular calibration opening formed by the plurality of lamellar blocks can be adjusted as required. The lamellar blocks described in DE 198 43 340 C2 each consist of a large number of lamellas which are threaded onto two spaced-apart support rods. Spacer sleeves are used to maintain a desired distance between adjacent slats (see also FIG. 3 of DE 19843 340 C2). An example of a threaded lamella block is also shown in FIG. 1 a. The lamella block 10 shown in FIG. 1 a comprises a multiplicity of lamellae 12 and spacer sleeves 14 which are alternately threaded along second support rods 16. Such threaded lamella blocks are complex to manufacture and thus costly.

In a departure from the threaded lamella blocks described above, lamella blocks with closed support structures (or back structures) are also known. Figure 1b shows an example of such a lamella block. The lamellar block 20 comprises a multiplicity of lamellas 22, which are supported by a back structure 24 in the form of a block. The block-shaped back structure 24 is implemented in the form of a one-piece body (e.g. a rod-shaped body). Further examples of lamellar blocks with a closed back structure are known from WO 2004/103684 A1.

During a calibration process, the outer wall of the profile is pressed against the inner wall of the calibration basket (for example with the help of a vacuum). The inner wall of the calibration basket is formed by the lamellae of the interlocking lamellar blocks. Due to the pressure with which the profile, which is still deformable at this point in time, is pressed against the inner wall of the calibration basket, buckling areas inevitably form on the surface of the profile in the spaces between the lamellas (also called grooves). The dimensions of the buckling areas depend on the length and width of the grooves. However, large buckling areas are unfavorable with regard to the surface of the calibrated profile. Furthermore, when the profile to be calibrated is advanced through the calibration cage of the calibration device, already generated buckling fields "snap into" subsequent grooves in the lamellar blocks. The repeated latching of the bumps into the grooves leads to an undesirable rattling of the profile to be calibrated in the calibration cage the repetitive embossing of the lamellar structure on the profile surface reinforces the bulge structure on the profile surface.

The object of the present invention is to provide lamellar blocks for a calibration device which further reduce or eliminate the problems identified in connection with the prior art. In particular, it is the object of the present invention to improve the surface structure of the profile to be calibrated. Furthermore, the chattering of the profile to be calibrated observed in connection with known calibration blocks should at least be reduced or even avoided entirely.

To achieve the above-described and other objects, a lamella block for a calibration device for calibrating an extruded profile is provided. The lamellar block comprises a lamellar structure which has a plurality of lamellas which are spaced apart from one another by grooves and are arranged in the longitudinal direction of the lamellar block. At least some of the grooves each have a web element which divides the respective groove into two groove sections on an inside of the lamella block.

The profile to be calibrated can be a plastic profile. In particular, the profile to be calibrated can be a pipe. The longitudinal direction of the lamellar block corresponds to the extrusion direction (the feed direction) of the profile to be calibrated when the lamellar block is installed in a calibration device. The inside of the lamellar block is the side of the lamellar block that faces the profile to be calibrated.

Each of the web elements arranged in a respective groove can be fixed laterally on at least one of the lamellae (ie on the respective lamella flank) which form the respective groove. It goes without saying that the width of each web element (ie its extension in the longitudinal direction of the lamella block) can correspond to the width of the groove in which the respective web element is arranged. Each of the web elements can be arranged in a respective groove in such a way that it ends flush with the lamella block on the inside. In other words, each web element has a contact surface on the inside of the lamella block, which is flush with the respective contact surface of the adjacent lamellae. Thus, the contact surfaces of all web elements and the contact surfaces of all lamellae form a common contact surface of the lamella block, which comes into contact with the outer surface of the profile to be calibrated.

According to a variant, the groove sections of a groove defined by a respective web element can be unequal. In other words, the groove sections on both sides of the respective bar element can be designed to be of different lengths on the inside of the lamella block. The division of the groove into two unequal groove sections can be achieved by a web element which has an asymmetrical cross-section in a plane perpendicular to the longitudinal direction of the lamella block. Such a web element can have an asymmetrical contact surface, so that when the web element is arranged in the groove, it inevitably breaks up into two unequal groove sections.

The length of the groove sections of two adjacent grooves can vary from one another. That is to say, the groove sections of two adjacent grooves can have different lengths on the inside of the lamellar block. The variation of the length of the groove sections along the lamellar block can be achieved by arranging web elements with changing cross sections (or contact surfaces) in the respective grooves along the lamellar block. The cross section here again means the cross section of the web element perpendicular to the longitudinal direction of the lamella block.

The length variation of the groove sections of all grooves with respect to one another can follow a discontinuous function. In other words, the groove sections of all grooves can differ from one another in their respective length on the inside of the lamellar block in an irregularly variable manner. Alternatively, the variation can also follow a definable function. Each web element can protrude into the groove interior of the respective groove in which it is arranged. Each web element can have a maximum extension in the direction of the inside of the groove in a region in which the respective

Web element intersects a longitudinal plane of symmetry of the lamella block. The plane of symmetry runs through the center of the lamellar block and divides the lamellar block into two basically identical halves (without taking into account the bar elements).

The web elements can be positioned and / or dimensioned in the grooves in such a way that they do not impair the engagement of the lamellae of an adjacent lamella block of a calibration device in the grooves of the lamella block.

Each bar element can be curved inside the groove (convex). Alternatively, each web element can also assume a different shape in the interior of the groove. The shape and dimensioning of the bar elements inside the groove depends on the desired stability (strength, rigidity, etc.) of the bar elements, which in turn depends on the forces acting on the bar elements. Depending on the external requirements and the material used, the web elements can also be flat solid bodies (about the thickness of a film).

The lamellar block can furthermore have a support structure on which the lamellar structure is arranged. The support structure and the slats can be made from the same material or from different materials. In particular, the support structure and / or the lamellae can be formed from a metallic material or a polymer material. The carrier structure can be arranged on a side facing away from the inner side of the lamella block on the lamella structure of the lamella block. The carrier structure and the lamellar structure can be designed as a one-piece component. Alternatively, the support structure can comprise at least one support rod, along which the individual lamellae of the lamella block are threaded in the longitudinal direction. The lamellar block can be produced using 3D printing. Alternatively, the lamellar block can be produced, for example, by milling, drilling, cutting or by means of a casting process.

The lamellar block according to the invention is advantageous over the prior art in several respects. On the one hand, dividing the grooves into groove sections reduces the size of the buckling areas on the surface of the extruded profile during calibration. This can improve the surface quality of the calibrated profile. Furthermore, an irregular length variation of the groove sections on the inside of the lamellar block leads to a correspondingly uneven formation of bulge areas on the surface of the extruded profile. As a result, the rattling described at the outset can be prevented when calibrating the profile, since at least some buckling areas can no longer snap into the subsequent grooves due to their inequality. In addition, by choosing a suitable shape and dimensioning of the web elements inside the groove, it can be ensured that the engagement of the lamellae of adjacent lamella blocks of a lamella device in the grooves of the lamella block is not restricted.

According to a further aspect of the invention, a calibration device for calibrating extruded profiles is provided, the calibration device having a plurality of the lamellar blocks according to the invention which are arranged with respect to one another to form a calibration opening. The arrangement of the lamella blocks can be such that they form a circular calibration opening.

The calibration device can furthermore comprise a plurality of actuation devices, each of the actuation devices being coupled to one of the lamellar blocks. Anyone can use the actuator Lamella block can be operated individually radially to the calibration opening. As a result, the effective cross section of the calibration opening can be adapted to the cross section (diameter) of the profile to be calibrated as required.

Furthermore, the calibration device can have a housing which is provided for receiving and mounting the actuation device and the lamellar blocks coupled to the actuation device.

According to a further aspect of the present invention, a method for producing a lamellar block according to the invention is provided. The method for producing the lamella block comprises at least the step of producing the lamella block by means of 3D printing or by means of additive manufacturing. The production of the lamellar block using 3D printing processes or additive manufacturing processes can include laser sintering / laser melting of material layers in layers, with the material layers being applied one after the other (sequentially) according to the shape of the lamellar block to be produced.

The method can furthermore comprise the step of calculating a lamella block geometry (CAD data) and, optionally, converting the 3D geometry data into corresponding control commands for 3D printing or additive manufacturing.

The method can include manufacturing the lamella block as a one-piece component. It goes without saying, however, that according to an alternative variant, the method can comprise producing each lamella individually (e.g. with a respective web element in contact) and threading the lamellae along at least one support rod in the longitudinal direction of the lamella block.

According to a further aspect, a method for producing a lamellar block is provided, comprising the steps of: creating a data record which maps the lamellar block as described above; and Store the data set on a storage device or server. The

Method may further include; Entering the data record into a processing device or a computer which controls a device for additive manufacturing in such a way that it manufactures the lamellar block depicted in the data record.

According to a further aspect, a system for the additive manufacturing of a lamellar block is provided, with a data record generating device for generating a data record which maps the lamellar block as described above, a storage device for storing the data set and a processing device for receiving the data set and for such a control of a device for additive manufacturing so that it manufactures the lamella block shown in the data record. The storage device can be a USB stick, a CD-ROM, a DVD, a memory card or a hard disk. The processing device can be a computer, a server, or a processor.

According to a further aspect, a computer program or computer program product is provided, comprising data records which, when the data records are read in by a processing device or a computer, causes them to control an additive manufacturing device in such a way that the additive manufacturing device manufactures the lamella block as described above.

According to a further aspect, a computer-readable data carrier is provided on which the computer program described above is stored. The computer-readable data carrier can be a USB stick, a CD-ROM, a DVD, a memory card or a hard disk.

According to a further aspect, a data record is provided which maps the lamella block as described above. The data record can be stored on a computer-readable data carrier.

Figures 1a and 1b were already in connection with the prior art

Technology discussed at the beginning. Reference is made to the description there.

In connection with Figures 2a to 2c, an inventive

Lamella block 100 for a calibration device described further. The lamellar block 100 shown in FIG. 2a comprises a lamellar structure 110 which has a multiplicity of lamellas 112. Furthermore, the lamellar block 100 comprises a support structure 120. The support structure 120 functions as a support for the

Lamellar structure 110.

The lamella block 100 can also have a coupling device (not shown here) which is provided for coupling to an actuating device of a calibration device (also not shown here). The coupling device can be designed such that it can be firmly connected to the support structure 120.

The support structure 120 can be implemented (as shown in FIG. 2a) by a bar-shaped body, along which the lamellae 112 are arranged. In particular, the bar-shaped support structure 120 can have perforations to reduce the weight of the lamella block 100. Alternatively, the support structure 120 can have at least one support rod on which the lamellas 112 are threaded (compare FIG. 1 a).

The lamellar structure 110 comprises a multiplicity of lamellas 112, which are arranged at a distance from one another in the longitudinal direction L of the lamella block 100. Adjacent lamellae 112 are separated from one another by corresponding grooves 130. According to the implementation shown in FIG. 2a, each lamella 112 essentially has the contour of an (isosceles) triangle in cross section to the longitudinal direction L. On the inside of the lamellar block 100, which faces the profile to be calibrated when it is installed in a calibration device, each lamella has a contact surface 114. During calibration, the contact surface 114 comes into contact with the outer surface of the profile to be calibrated (for example a pipe). The contact surface 114 of each lamella 112 has a slight (concave) curvature and at least partially represents the outer contour of the profile to be calibrated. Depending on the application, the lamella block 100 can also have a different lamella shape, that of the triangular cross-sectional profile described here may differ. Likewise, the contact surfaces 114 of each lamella 112 can have a different curvature or be flat or angled.

The lamellar block 100 shown in FIG. 2a further comprises web elements 140 which are arranged in the grooves 130 of the lamellar block 100. The web elements 140 for their part have a contact surface on the inside of the lamella block 100

142, which ends flush with the contact surfaces 114 of the lamellae 112 adjacent to the respective web element 140. That is, the contact surfaces 114 of the lamellae 112 and the contact surfaces 142 of the web elements 140 form a common contact surface on the inside of the lamella block 100. The common contact surface can at least partially simulate the outer contour of the profile to be calibrated.

FIG. 2b shows a normal view of the lamella block 100 shown in FIG. 2a on the inside of the lamellae. The carrier structure 120, along which the lamellae 112 are arranged, is indicated in the normal view in FIG. 2b as a vertical bar lying behind the lamellae 112. The lamellar block 100 is designed mirror-symmetrically to a plane of symmetry 180 which runs centrally through the lamellar block in the longitudinal direction. The contact surfaces 142 of the web elements 140 are shown hatched in FIG. 2b. The web elements 140 are arranged in the longitudinal direction L centrally (i.e. centrally along the plane of symmetry 180) in the grooves 130 of the lamellar block 100 such that each web element 140 divides an associated groove 130 into two identical groove sections 132, 134.

FIG. 2c shows a cross section of the lamella block shown in FIGS. 2a and 2b in the sectional plane AA (see FIG. 2b). The contact surface 142 of the web element 140 ends flush with the contact surface 114 of the adjacent lamella 112. The web element 140 also has a web element back 144 with which the web element 140 projects into the inside of the groove 130. On its back 144, the web element 140 has a rounded shape which, in cross section, is symmetrical to the plane of symmetry 180 is. It goes without saying that the web element back 144 can also be embodied as angular. Regardless of its exact rear configuration, the web element 140 protrudes furthest into the groove 130 at that point at which it intersects the plane of symmetry 180.

A further lamella block 200 according to the invention for a calibration device will now be described in more detail in connection with FIG. 3a. Like the lamellar block 100 according to FIGS. 2a to 2c, the lamellar block 200 has a lamellar structure 110 with a multiplicity of lamellae 112 which are spaced apart from one another by grooves 130. The lamellar block 200 also has a support structure 120 on which the lamellar structure 110 is arranged. The carrier structure 120 can be designed in exactly the same way as the carrier structure of the lamellar block 100. Reference is made to the corresponding description above. For the sake of simplicity, those features of the lamella block 200 which are structurally and functionally similar or identical to features of the lamella block 100 have been given the same reference numerals,

Web elements 240 are arranged in the grooves 130. The web elements 240 are designed such that at least some of the grooves 130 are divided into unequal groove sections 232, 234 with respect to the plane of symmetry 180 on the inside of the lamella block 200. As a result, buckling fields of different lengths can form on the surface of the profile to be calibrated during calibration. Chattering during the calibration of the profile can thus be considerably reduced or even completely prevented.

In the following, exemplary configurations of web elements 240a to 240f of the lamella block 200 according to FIG. 3a are described in more detail in connection with FIG. 3b. The contact surfaces 242a to 242f have a slight (concave) curvature. Depending on the contour of the component to be calibrated, the configuration of the contact surface 242 of each web element 240 can also vary. Each bar element 240a to 240f also has a bar element back 244a to 244f, with which it protrudes into the groove interior of a respective groove 130. The web element backs 244a to 244f each have a curved surface.

In cross section, at least some of the web elements 240a to 240f can be designed asymmetrically (cf. web elements 240b, 240c, 240d and 240f) with respect to the plane of symmetry 180. In other words, at least some of the web elements 240 can have an inherently asymmetrical cross section. Furthermore, some or all of the web elements 240 can have cross-sections which are asymmetrical to one another. Each of the web elements 240a to 240f has its greatest extent at the point at which it intersects the plane of symmetry 180 of the lamella block 200.

An implementation of a calibration device 500 according to the invention will now be described in greater detail in connection with FIG. The calibration device 500 comprises a plurality of the above-described lamella blocks 100, 200 according to the invention, which are arranged in the circumferential direction to one another in such a way that the contact surfaces 114 of the lamellae 112 and the contact surfaces 142, 242 of the web elements 140, 240 of the lamella blocks 100, 200 together have a calibration opening 510 form. The calibration opening 510 corresponds to the desired outer contour of a profile to be calibrated (tube 515).

A coupling device 150 is arranged on the support structure 120 of each lamella block 100, 200. Each coupling device 150 is in turn connected to a respective actuating device 520, which is fixed between an inner housing cylinder 530 and an outer housing cylinder 540 of the calibration device 500. The actuation of a lamella block 100, 200 by an associated actuation device 520 enables the lamella block 100, 200 to be moved radially. In this way, the diameter of the calibration opening 510 can be set variably, since the lamellae 112 of each lamella block 100, 200 in the grooves 130 of each adjacent lamella blocks 100, 200 engage. In principle, the structure of the calibration device 500 according to FIG. 4 is similar to the structure of a calibration device, as already described in DE 198 43 340 C2.

FIG. 5 schematically shows an arrangement of the lamella blocks 200 shown in FIG. 3a within a calibration device. The respective web elements 240 of each lamella block 200 have their respective largest radial ones

Expansion (expansion in the direction of the inside of the groove) in the area in which they intersect the plane of symmetry 180 of the respective lamella block 200. The web elements 240 are dimensioned so that engagement of the lamellae 112 of adjacent lamella blocks 200 is not restricted. The illustration according to FIG. 5 applies analogously to the engagement of lamellar blocks 100 according to the invention (compare FIGS. 2a-2c) with symmetrical web elements 140 which divide the grooves 130 into identical groove sections 131, 134.

A generative or additive manufacturing method can preferably be used to manufacture a lamella block 100, 200 according to the invention. Such a production method 600 is shown in FIG. Accordingly, a 3D printing process is used. In this case, in a first step 610, 3D geometry data (CAD data) which correspond to the geometry of the lamella block 100, 200 to be manufactured are calculated. In a second step 620, the calculated 3D geometry data are converted into control commands for a 3D print. In a third step 630, based on the generated control commands, the lamella block 100, 200 is finally built up in layers by means of a 3D printing process (e.g. laser sintering, laser melting). A metallic material or a polymer material can be used as the material for 3D printing.

It goes without saying that, according to an alternative variant, the method can include producing each lamella 112 individually (for example, each with an adjacent web element 140, 240) and threading the lamellae 112 along at least one support rod in the longitudinal direction of the lamella block 100, 200. As an alternative to production using 3D printing, it is also conceivable to use the lamella block

100, 200 or each lamella 112 can be produced individually, for example by milling, drilling, cutting or by means of a casting process.

By using the lamellar blocks with web elements described here, the calibration of endless profiles, in particular of plastic profiles, can be further improved. In particular, an advantageous reduction in the size of the buckling areas on the surface of the profile can be achieved. Furthermore, irregular groove section patterns and thus irregular buckling areas on the profile surface can be realized by the web elements in the longitudinal direction of the lamellar blocks, whereby the chatter when calibrating the profile is eliminated or at least greatly reduced.
