Description

Fin-shaped block for calibration device with web on the inside

The present invention relates to a fin-shaped block used for calibrating an extruded profile calibration device. The present invention further relates to a calibration device including a plurality of fin-shaped blocks, a method for producing fin-shaped blocks, a system for layered manufacturing of the fin-shaped blocks, and corresponding computer programs and data sets.

The calibration device is used to calibrate extruded annular profiles, such as pipe profiles. In the production of such profiles, the desired plastic melt for the production of profiles is first produced in an extruder. The produced plastic melt is then pressed through the exit nozzle of the extruder, which specifies the shape of the profile. Then, the profile from the exit nozzle of the extruder passes through a calibration device, which performs post-forming of the still heated profile with dimensional accuracy.

This calibration device for determining the size of extruded profiles is known from DE 198 43 340 C2. Among them, a calibration device with variable energy adjustment is taught. The calibration device is constructed for calibrating extruded plastic pipes with different pipe diameters. The calibration device includes a housing and a plurality of fins arranged in the housing in a circular shape, which together form a calibration basket with a circular calibration opening, and the pipe to be calibrated is guided through the calibration opening (in particular, refer to DE 198 43 340 Figures 1 and 2 of C2). Furthermore, each fin-shaped block is coupled with an actuating device that provides each radial displacement of the individual fin-shaped block. In this way, if necessary, the effective cross-section of the circular calibration opening formed by the plurality of fin-shaped blocks can be adjusted accordingly.

The fin-shaped blocks described in DE 198 43 340 C2 are respectively composed of a plurality of fins, which are strung together on two load-bearing rods arranged apart from each other. In order to maintain the desired distance between adjacent fins, spacer sleeves are used (see also Figure 3 of DE 198 43 340 C2). An example of strung fins is further shown in FIG. 1a. The fin block 10 illustrated in FIG. 1 a includes a plurality of fins 12 and spacer sleeves 14 which are strung alternately along the second supporting rod 16. This stringed fin-shaped block is troublesome to manufacture and therefore costly.

Furthermore, unlike the above-mentioned stringed fin-shaped blocks, fin-shaped blocks having a closed carrier structure (or individual ridge structure) are known. Figure 1b shows an example of this fin-shaped block. The fin block 20 includes a plurality of fins 22 which are carried by a ridge structure 24 formed in a block manner. The block-shaped spine structure 24 is realized here in the form of a monolithic body (for example, a rod-shaped body). Other examples of fins with closed ridge structures are known from WO 2004/103684 A1.

During the calibration process, the outer wall of the profile is pressed against the inner wall of the calibration basket (for example, by vacuum). The inner wall of the calibration basket is formed by the fins of the fin-shaped blocks that mesh with each other. After pressing the still deformable profile against the inner wall of the calibration basket, a convex area is inevitably formed on the surface of the profile in the intermediate space (also called groove) of the fin. The size of the raised area is consistent with the length and width of the groove. However, relative to the surface of the calibration profile, a large raised area is disadvantageous. Furthermore, during the feeding of the profile to be calibrated by the calibration basket of the calibration device, the already generated raised area "hooks" enter the subsequent groove of the fin-shaped block. The repeated hooking of the protrusion into the groove causes undesirable vibration of the profile that will be calibrated in the calibration basket. On the other hand, the fin structure is repeatedly stamped on the surface of the profile to enhance the convex structure on the surface of the profile.

The object of the present invention is to provide a fin-shaped block for a calibration device, which reduces or eliminates the problems indicated in the prior art. In particular, the object of the present invention is to improve the surface structure of the profile to be calibrated. Furthermore, the observation of the known calibration block reduces or completely avoids the vibration of the profile to be calibrated.

In order to solve the above problems and other problems, a fin-shaped block for calibrating an extruded profile calibration device is provided. The fin block includes a fin structure having a plurality of fins separated from each other by grooves and arranged in the longitudinal direction of the fin block. At least some of the grooves respectively have at least one web element, so that the individual grooves on the inner side of the fin-shaped block are divided into at least two groove parts.

The profile to be calibrated can be a plastic profile. In particular, the profile to be calibrated can be a (plastic) pipe. When the fin-shaped block is installed into the calibration device, the longitudinal direction of the fin-shaped block corresponds to the extrusion direction (feeding direction) of the profile to be calibrated. The inner side of the fin-shaped plate is the side of the fin-shaped plate facing the profile to be calibrated. This means that each fin has a contact surface on the inside of the fin block that is in contact with the outer surface of the profile to be calibrated during calibration.

Each web element arranged in the individual grooves can be laterally fixed on at least one fin (for example, on the side of the individual fin), and the individual grooves are formed between the fins. It should be understood that the width of each web element (that is, its range in the longitudinal direction of the fin-shaped block) may correspond to the width of the groove in which the individual web element is arranged.

Each web element can be arranged in an individual groove in such a way that it (that is, each web element) terminates on the inner side flush with the fins. In other words, each web element has a contact surface on the inner side of the fin-shaped block, the contact surface terminating flush with the individual contact surface of the adjacent fin. Therefore, the contact surfaces of all the web elements and the contact surfaces of all the fins form a shared contact surface of the fin block, which contact surface will be in contact with the outer surface of the profile to be calibrated during calibration.

According to a preferred variant, the web elements of at least some of the grooves can be arranged offset relative to each other. Therefore, at least some of the grooves may have groove portions that are different from each other (that is, different in length). The offset of the web elements relative to each other can cause the web elements arranged throughout the entire length of the fin to form a composite web section (ie, lateral to the longitudinal direction), the composite web The cross section is larger than the cross section of each individual web element. The resultant web section may mean the protruding part of the cross section of all web elements of the fin-shaped block in a plane lateral to the longitudinal direction of the fin-shaped block. The offset of the two web elements located in different grooves with respect to each other may mean that these web elements are not arranged completely consistent with each other. In particular, the contact surfaces of the web elements can be arranged offset with respect to each other, and therefore follow a route on the inside of the fin-shaped block, viewed over the entire length of the fin-shaped block, which is not all parallel In the longitudinal direction of the fin-shaped block. The contact surfaces of all web elements can have the same size. The profile to be calibrated is fed in the longitudinal direction along the contact surface of the fin-shaped block, so the convex areas appearing on the surface of the profile during calibration can be smooth across a wide range.

In at least one groove of the fin-shaped block and viewed across the entire length of the fin-shaped block, a predetermined number of web elements can be arranged in such a manner that the web elements are described in a discontinuous path in the longitudinal direction. According to how many web elements are arranged in the groove, the corresponding groove is divided into two (in the case of one web element), three (in the case of two web elements), or more than three (in the case of more than two web elements). In the case of web elements) the groove part. One or more grooves may not even have web elements.

In some or each groove of the fin-shaped block, viewed across the total length of the fin-shaped block, the first web element can be arranged in such a way that the first web element describes an inclined or curved route in the longitudinal direction . Instead of an inclined or curved route, the configuration of the first web element can also have a zigzag shape or a different route. For the arrangement of the first web element on the inside of the fin-shaped block, it is essential that the route of the first web element is not completely parallel to the longitudinal direction of the fin-shaped block (and therefore parallel to the progress of the profile to be calibrated). Give directions).

In addition to the first web element, viewed across the entire length of the fin-shaped block, in some or each groove, the second web element can describe the course of the inclined or curved in the longitudinal direction on its inner side. The second web element is arranged in such a way that the second web element is arranged spaced apart from the first web element. Here, the route of the second web element may be parallel to the route of the first web element. For alternatives to inclined or curved routes, the second web element can also follow a zigzag or different route.

Furthermore, the fin-shaped block may have a carrier structure on which the fin structure is arranged. The carrier structure and the fin-shaped block may be made of the same material or of different materials. In particular, the carrier structure and/or the fins may be formed of metal materials or polymer materials. The carrier structure can be arranged on the fin structure of the fin block on the side facing away from the inner side of the fin block. The carrier structure and the fin structure may be formed as a one-piece component. Alternatively, the carrying structure may include at least one carrying rod, and the individual fins of the fin-shaped block are strung in the longitudinal direction along the carrying rod.

Fin-shaped blocks can be produced by 3D printing. Alternatively, the fins can be produced, for example, by milling, drilling, cutting, or by casting methods.

From various viewpoints, the fin-shaped block system according to the present invention is advantageous compared to the prior art. On the one hand, dividing the groove into groove portions allows the raised area on the surface of the extruded profile to be reduced during calibration. This can improve the surface condition of the calibration profile. Furthermore, the offset of the web elements of adjacent grooves relative to each other results in irregular variations in the length of the groove portion. Therefore, during calibration, irregularly formed convex areas appear on the surface of the profile to be calibrated. As a result, chattering during the calibration of the profile described in the introduction can be prevented, because at least some of the raised areas no longer snap into the subsequent grooves (or individual groove parts) due to their unevenness.

According to another aspect of the present invention, a calibration device for calibrating extruded profiles is provided, wherein the calibration device has a plurality of fin-shaped blocks according to the invention, and the fin-shaped blocks are arranged relative to each other to form a calibration opening. The fins can be arranged in such a way that they form a circular calibration opening.

Furthermore, the calibration device may include a plurality of actuation devices, wherein each actuation device is respectively coupled to one of the fins. Through the actuation device, each fin-shaped block can be actuated to the calibration opening individually in the radial direction. Therefore, the effective cross section of the calibration opening can be designed to be suitable for the cross section (diameter) of the profile to be calibrated as required.

Furthermore, the calibration device may have a housing provided for receiving and storing the actuating device, and a fin-shaped block coupled with the actuating device.

According to another aspect of the present invention, a method for producing the fin-shaped block according to the present invention is provided. The method for producing the fin-shaped block at least includes the step of producing the fin-shaped block by 3D printing or by a layered manufacturing method. The production of fins by the 3D printing method or the multi-layer manufacturing method may include layer-by-layer laser sintering/laser melting of material layers, which are applied continuously (in order) according to the form of the fins to be produced Material layer.

Furthermore, the method may include the step of calculating the geometry of the fins (CAD data), and optionally, the step of converting the 3D geometry data into corresponding control commands for 3D printing or multilayer manufacturing.

The method may include producing the fin block as a one-piece part. It should be understood that, according to an alternative variant, the method may include producing each fin individually (for example, each having adjacent web elements), and at least one load-bearing rod string along the lengthwise direction of the fin block From the fins.

According to another aspect, a method for producing fin-shaped blocks is provided. The method includes the following steps: creating a data set representing the fin-shaped blocks as described above; and storing the data set on a storage device or a server. The method may further include: inputting the data set into a processing device or a computer, and the processing device or computer activates the device for multi-layer manufacturing in such a way that the fin-shaped block represented in the data set is manufactured.

According to another aspect, a system for layered manufacturing of fin-shaped blocks is provided. The system has a data set generating device for generating a data set representing the fin-shaped block as described above; and a storage device for storing the A data set; and a processing device for receiving the data set and actuating the device for layered manufacturing in such a way that the device for layered manufacturing manufactures the fin-shaped block represented in the data set. The storage device can be a USB memory stick, CD-ROM, DVD, memory card, or hard disk. The processing device can be a computer, a server, or a processor.

According to another aspect, a computer program is provided or a computer program product containing a data set is provided separately, and the device used for multilayer manufacturing is made into the fin-shaped block as described above, and the data set is read by the processing device or the computer. Cause it to actuate the device used for multilayer manufacturing.

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

According to another aspect, a data set representing the fin-shaped block as described above is provided. The data set can be stored on a machine-readable data carrier.

Figures 1a and 1b have already been discussed in the preface regarding the prior art field. Will refer to the description there.

With regard to FIGS. 2a to 2c, the fin-shaped block 100 for the calibration machine according to the present invention will now be further described.

The fin block 100 illustrated in FIG. 2a includes a fin structure 110 having a plurality of fins 112. Furthermore, the fin block 100 includes a carrier structure 120. The carrier structure 120 serves as a carrier of the fin structure 110.

Furthermore, the fin-shaped block 100 may have a coupling device (not illustrated here) provided for coupling with an actuating device (also not illustrated here) of the calibration device. The coupling device can be constructed so that it can be firmly connected to the carrier structure 120.

The carrier structure 120 (as illustrated in FIG. 2a) can be realized by a beam-shaped body, and the fins 112 are arranged along the beam-shaped body. In particular, the beam-shaped supporting member structure 120 may have holes for reducing the weight of the fin block 100. Alternatively, the carrier structure 120 may have at least one carrier rod on which the fin 112 is strung (refer to FIG. 1a for this).

The fin structure 110 includes a plurality of fins 112 which are arranged spaced apart from each other in the longitudinal direction L of the fin block 100. Adjacent fins 112 are separated from each other by corresponding grooves 130. According to the embodiment shown in FIG. 2a, each fin 112 has a substantially (equilateral) triangular profile in the cross section in the longitudinal direction L. On the inner side of the fin block 100, each fin has a contact surface 114 in the calibration device facing the profile to be calibrated in the installed state.

During calibration, the contact surface 114 will be in contact with the outer surface of the profile to be calibrated, such as a pipe. The contact surface 114 of each fin 112 has a slight (concave) curvature, which at least partially represents the outer contour of the profile to be calibrated. According to the present application, the fin block 100 may also have different fin shapes, which may be different from the triangular cross-sectional profile described herein. Likewise, the contact surface 114 of each fin 112 may have a different curvature, or may be constructed separately so as to be flat or angled.

The fin block 100 illustrated in FIG. 2 a further includes a web element 140 a disposed in the groove 130 of the fin block 100. The web elements 140a respectively have contact surfaces 142a on the inner side of the fin-shaped block 100, and the contact surfaces terminate flush with the contact surfaces 114 of the fins 112 adjacent to the individual web elements 140a. This means that the contact surface 114 of the fin 112 and the contact surface 142 a of the web element 140 a form a common contact surface on the inner side of the fin block 100. The common contact surface can at least partially reproduce the outer contour of the profile to be calibrated.

In FIG. 2b, a front vertical view of the fin block 100 illustrated in FIG. 2a on the inner side of the fin is illustrated. In the front vertical view in FIG. 2b, the carrier structure 120 along which the fin 112 is arranged is indicated as an upright beam located behind the fin 112. The fin block 100 is formed mirror-symmetrically with respect to a symmetry plane 180 extending through the fin block in the center in the longitudinal direction L. The contact surface 142a of the web element 140a is illustrated with hatching in FIG. 2b. In such a way that each web element 140a divides the associated groove 130 into two equal groove portions 132, 134, the web element 140a is centered in the longitudinal direction L (that is, centrally along the plane of symmetry 180). ) Is arranged in the groove 130 of the fin block 100. The web element 142 arranged in the groove 130 or its contact surface 142a respectively on the inner side of the fin block causes the size of the raised area formed on the surface of the calibration profile to be reduced, thereby improving the surface condition of the calibration profile.

In Fig. 2c, the section of the fin-shaped block illustrated in Figs. 2a and 2b is illustrated in section A-A (see Fig. 2b). The contact surface 142a of the web element 140a terminates flush with the contact surface 114 of the adjacent fin 112. Furthermore, the web element 140a has a back 144 of the web element, and the web element 140a protrudes into the groove of the groove 130 through the back 144. The web element 140a has a circular shape on its back surface 144, and its cross-section is symmetrical with respect to the symmetry plane 180. It should be understood that the back 144 of the web element may also be formed to be angled.

With regard to FIGS. 3a and 3b, other variants of the fin-shaped block 200 for the calibration device according to the present invention will now be described in more detail. Similar to the fin block 100 according to FIGS. 2a to 2c, the fin block 200 has a fin structure 110 provided with a plurality of fins 112 which are separated from each other by grooves 130. Furthermore, the fin block 200 has a carrier structure 120 on which a fin structure 110 is disposed. Here, the carrier structure 120 can be constructed as the carrier structure of the fin-shaped block 100 in FIGS. 2a to 2c. Reference will be made to the corresponding description of FIGS. 2a to 2c. For simplicity, the features of the fin block 200 that are similar or identical in structure and function to the features of the fin block 100 are given the same reference numerals in FIGS. 3a and 3b.

According to the present invention in a variant of the fin block 200 described in Figures 3a and 3b, at least some of the web elements 140a can be arranged offset relative to each other. Therefore, at least some of the web elements 140a divide the groove 130 disposed therein into unequal groove portions (132, 134) (ie, unequal lengths). The offset of the web elements 140a causes the contact surfaces 142a to be offset relative to each other, and has the result that the feed of the profile of the contact surfaces 142a is calibrated along the longitudinal direction of the fin block 200, and the webs are arranged in line with each other Compared with the element 140a, the web element generally passes through a larger surface area of the profile. By feeding the profile to be calibrated along the contact surface 142a of the fin-shaped block 200, the convex areas appearing on the profile surface during calibration can be smooth across a wide range.

According to the variant in FIG. 3a, viewed across the entire length of the fin 200, the web element 140a follows a linearly inclined path relative to the plane of symmetry 180. On the other hand, according to the variant in Fig. 3b, the web element 140a on the inner side of the fin-shaped block 200 depicts a curved or individually undulating course. According to alternative variants, the web elements 140a also follow a zigzag or different route. In other words, the web element 140a is arranged in the groove 130 in such a way that it follows a predetermined route.

For each web element 140a, the thickness of each web element 140a protruding into the groove of the groove 130 can vary. For example, the thickness of the web element 140a may increase as the distance of the web element 140a from the plane of symmetry 180 increases. As a result, collisions between the fins of the adjacent fin-shaped blocks in the calibration device and the web element 140a can be prevented.

With regard to FIGS. 4a and 4b, other modifications of the fin 300 for the calibration device according to the present invention are described in further detail. For the sake of simplicity, the features of the fin-shaped block 300 are again similar or the same in structure and function as the features of the fin-shaped block 100 according to FIGS. 2a-2c, and the same reference numerals are given. Reference will be made to the corresponding description of Figures 2a-2c.

According to the modification of the fin 300 shown in Fig. 4a, each groove 130 includes a first web element 140a and a second web element 140b. The web elements 140a, 140b divide each groove into three groove portions 132, 133, 134. The first web element 140a and the second web element 140b are arranged in such a way that the groove portions 132, 133, 134 formed by at least some of the grooves 130 have unequal lengths. In this way, it is possible to reduce or even prevent chattering during the calibration of the extruded profile described in the introduction. Viewed across the total length of the fin 300, the arrangement of the first web element 140a and the arrangement of the second web element 140b respectively follow a predetermined route. The configuration of the first web element 140a follows a linearly inclined route with respect to the symmetry plane 180. The route of the second web element 140b is also linearly inclined with respect to the symmetry plane 180 and parallel to the route of the first web element 140a. Compared with the variant where each groove 130 is separated by only one web element 140a (see FIGS. 3a and 3b), the advantage of separating the two web elements 140a, 140b is that each groove portion 132, 133, 134 and therefore the convex area on the surface of the profile is once again reduced, thereby further improving the surface condition of the profile to be calibrated.

According to the variant of the fin 300 shown in Fig. 4b, some grooves 130 have one web element 140a or two web elements 140a and 140b, while other grooves 130 do not have web elements 140a, 140b. Viewed across the total length of the fin 300, the configuration (displacement) of the web elements 140a, 140b can follow a non-constant function here. Therefore, a random distribution of raised areas of different lengths can be achieved on the surface of the calibration profile. With the random and at least partially offset configuration of the web elements 140a, 140b shown in Figure 4b, it can again be obtained that, compared with the case of web elements of the same configuration, the surface of the profile is passed during calibration Larger area.

With regard to FIG. 5, the embodiment of the calibration device 500 according to the present invention will now be described in further detail. The calibration device 500 includes the plurality of fin blocks 100 and 200 according to the present invention as described above, so that the contact surface 114 of the fin 112 and the contact surfaces 142a and 242 of the web elements 140a and 240 of the fin blocks 100 and 200 are together In the manner of forming the calibration opening 510, the fins are arranged in the circumferential direction relative to each other. The calibration opening 510 corresponds to the desired outer profile (tube 515) of the profile to be calibrated.

A coupling device 150 is arranged on the carrier structure 120 of each fin-shaped block 100 and 200. Each coupling device 150 is again connected to the actuation device 520 respectively, which is fixed between the inner shell cylinder 530 and the outer shell cylinder 540 of the calibration device 500. The fin-shaped blocks 100 and 200 are actuated by the associated actuating device 520 so that the fin-shaped blocks 100 and 200 can move radially. In this way, the diameter of the calibration opening 510 can be adjusted in a variable manner because the fin 112 of each fin 100, 200 engages into the groove 130 adjacent to the fin 100, 200, respectively.

Basically, the structure of the calibration device 500 according to FIG. 5 is similar to the structure of the calibration device as described in DE 198 43 340 C2.

In order to produce the fin-shaped blocks 100 and 200 according to the present invention, it is preferable to use a method of generating or individually layered manufacturing. This production method 600 is shown in FIG. 6. Therefore, 3D printing method is used. Here, in the first step 610, the 3D geometry (CAD data) corresponding to the geometry of the fins 100 and 200 to be manufactured is calculated. In the second step 620, the calculated 3D geometric shape is converted into a control command for 3D printing. Finally, in the third step 630, based on the generated control commands, the fin blocks 100 and 200 are built layer by layer by a 3D printing method (for example, laser sintering, laser melting). Metal materials or polymer materials can be used as materials for 3D printing.

It should be understood that according to alternative variants, the method may include individually producing each fin 112 (for example, having adjacent web elements 140a, 240), and along the longitudinal direction of the fins 100, 200 At least one supporting rod strung the fin 112.

In addition to production by 3D printing, it is also conceivable to individually produce the fin blocks 100 and 200 or to produce each fin 112 individually by milling, drilling, cutting, or by casting methods.

The use of the fin-shaped blocks and web elements described here can improve the alignment of ring profiles, especially plastic profiles, compared with the prior art. In particular, it is possible to achieve a favorable reduction of the raised area on the surface of the profile. Furthermore, as described above, through the at least partial offset arrangement of the web elements in the longitudinal direction of the fin-shaped block, irregular groove partial patterns and therefore irregular convex areas on the surface of the profile can be realized, This eliminates or at least greatly reduces vibration during profile calibration. Through the at least partial offset configuration of the web elements, even when the individual web elements or their individual contact surfaces are constructed identically, irregular raised areas can be realized on the surface of the profile.
