Description

Technical Field

[0001] This invention relates to a frame for a through-bar system for guiding cables and / or conduits through openings in a partition. Such a frame includes an axis, frame walls, and an axially extending through opening for accommodating one or more sealing modules of the through-bar system, wherein the frame walls have inner and outer surfaces. Some types of frames also have flanges for engaging the partition.

[0002] The present invention also relates to a through-bar system for guiding cables and / or conduits through openings in a partition, wherein the through-bar system includes the frame and one or more sealing modules disposed within the frame for sealingly holding one or more cables or conduits. Such a through-bar system further includes a compression unit for compressing the one or more sealing modules within the frame to hold the cables or conduits and seal the through-bar system.

[0003] The present invention also relates to the use of such frames in perforated systems. The present invention further relates to a method of providing such a perforated system. Background Technology

[0004] Various perforation systems and frames for such systems are known in the prior art. Perforation systems are used to guide cables and conduits through partitions, such as walls, floors, and ceilings. Perforation systems are used in many different environments, including cabinets, junction boxes, machines, and similar installations, as well as various industrial applications such as automotive and rail applications, communications, power generation and distribution, and marine and offshore applications. Perforation systems typically require sealing capabilities, such as sealing against different types of liquids (e.g., water) and / or gases (e.g., air), depending on the application requirements. To provide fastening and / or sealing, cables or conduits are typically arranged within a through opening in a sealing module. A common type of such module comprises two opposing module halves arranged around the cable or conduit, with the modules positioned within a frame in the partition opening. The modules within the frame are then compressed by a compression unit, pressing them against the inside of the frame, against each other (if applicable), and against the cables or conduits within the modules to secure the modules and cables or conduits and seal the perforation system. This barrier system can be arranged to seal against liquids (such as water), gases, fire, rodents, termites, dust, moisture, etc. The barrier system and modules can be arranged, for example, to receive cables for electricity, communications, computers, etc., or for pipes containing various gases or liquids, such as water, compressed air, hydraulic oil, and cooking gas.

[0005] One drawback of existing barrier penetration systems is that they are sometimes difficult to install. Another drawback is that leaks are sometimes found in existing barrier penetration systems. Therefore, further improvements to existing barrier penetration systems and their components are needed. Summary of the Invention

[0006] In view of the above, one object of the present invention is to provide a frame for a through-bar system for guiding cables and pipes through a partition, which is easy to install and produces a more reliable through-bar system.

[0007] This invention relates to a frame for a perforation system for guiding cables and / or conduits through openings in a partition, wherein the frame includes an axis, frame walls, and an axially extending through opening for accommodating one or more sealing modules of the perforation system, wherein the frame walls have inner and outer surfaces, wherein the frame includes a flange projecting radially outward from the outer surface of the frame walls, and wherein the flange includes a radially extending surface for engaging the partition, uniquely characterized in that the flange forms an inclined surface opposite the radially extending surface, and the flange includes a weld ridge extending radially outward from the inclined surface, wherein the weld ridge is at least partially fusible during welding to weld the frame to the partition, such that at least a portion of the weld ridge forms a weld joint for connecting the frame to the partition. This invention facilitates the installation and welding of the frame to the partition and reduces the risk of leakage in the perforation system. The weld ridge is arranged as material forming the weld joint, or at least provides material for the weld joint. Alternatively, during the welding process, additional welding material can be added in addition to the material from the welding ridge. This additional welding material can be added in a conventional manner, such as by filler metal, consumable welding wire electrodes, or similar methods. Facilitating welding of the frame can improve the strength and sealing performance of the through-wall system.

[0008] The weld ridge can extend from the inclined surface to the radially extending surface. Therefore, the weld ridge can form the tip of the flange, thereby partially contacting the partition while being exposed to the welding process from the opposite direction, to achieve efficient welding and reliably connect the frame to the partition.

[0009] The flange can extend continuously around the outer surface of the frame wall. This facilitates continuous contact between the frame and the partition, providing a strong connection and enabling a sealed perforated system.

[0010] The weld ridge can extend continuously around the flange to facilitate continuous weld joints around the entire frame, thereby providing a rigid connection and a tightly sealed perforated system.

[0011] The frame can be formed as a single integral piece, for example, made of metal such as aluminum, stainless steel, or other metals suitable for welding to the partition. For example, the weld ridge can be made of the same material as the rest of the frame. Alternatively, the weld ridge can be made of a different material, such as a material with a lower melting point than the rest of the frame. For example, the weld ridge may contain a melting point lowering element such that at least the solidus temperature of the weld ridge is lower than the solidus temperature of the frame wall, and optionally also lower than the solidus temperature of the rest of the flange.

[0012] The frame may include a slot on its inner surface. This slot may be elongated and extend along the frame wall in a direction perpendicular to the frame's axial direction. The slot is arranged to accommodate radially projecting portions of optional partition plates of the perforation system. This slot is particularly useful in perforation systems with a large axial dimension (i.e., a large axial extension).

[0013] The frame may include a first surface and an opposing second surface, wherein the first surface of the frame is inclined toward a flange. Therefore, it can effectively engage with a welding clamp without interfering with the area of ​​the outer surface of the frame wall on at least one side of the frame, thereby facilitating welding from at least that side even when the frame is attached to the welding clamp. The first and second surfaces may be the rear and front surfaces of the frame. Alternatively, the first surface may be arranged in a slot on the inner surface of the frame. The combination of the inclined first surface and the flange having an inclined surface and a welding ridge facilitates the installation of the frame while preventing frame deformation due to the welding process. The inclined first surface allows the welding clamp to engage the inclined first surface of the frame without obstructing the welding process on the same side as the inclined surface, thereby preventing frame deformation. Simultaneously, the flange with the inclined surface stabilizes the opposing sides of the frame and prevents deformation, while the welding ridge facilitates installation and reduces the risk of leakage.

[0014] The present invention also relates to a through-bar system for guiding cables and / or conduits through openings in a partition, wherein the through-bar system includes a frame, one or more sealing modules disposed within the frame for sealingly holding one or more cables or conduits, and a compression unit for compressing the one or more sealing modules within the frame, wherein the frame includes an axis, frame walls, and an axially extending through opening for receiving the one or more sealing modules of the through-bar system, wherein the frame walls have an inner surface and an outer surface, wherein the frame includes a flange projecting radially outward from the outer surface of the frame walls, and wherein the flange includes a radially extending surface for engaging the partition, uniquely wherein the flange forms an inclined surface opposite to the radially extending surface, and the flange is connected to the partition via a welded joint extending radially outward from the inclined surface. Therefore, a tight and reliable through-bar system can be obtained efficiently. The welded joint can be provided at least partially by a weld ridge of the flange. Thus, a portion of the flange forms the welded joint. The weld ridge can extend radially outward from the inclined surface, wherein the weld ridge at least partially melts during the welding process for welding the frame to the partition, such that at least a portion of the weld ridge forms a weld joint for connecting the frame to the partition. Alternatively, all material for the entire weld joint can be supplied by the weld ridge of the flange.

[0015] The invention also relates to the use of the frame in a perforation system for guiding cables and / or conduits through openings in a partition, wherein the frame is welded to the partition. The frame can be used in perforation systems having one or more sealing modules arranged within the frame. Each sealing module can sealably hold a cable, conduit, or blind plug. The frame can also be used in perforation systems that include a compression unit for compressing the one or more sealing modules arranged within the frame when each sealing module holds a cable, conduit, or blind plug.

[0016] The present invention also relates to a method for providing a perforated system, comprising the following steps:

[0017] a) Arrange the frame in the opening of the partition. b) Make the flange of the frame contact the partition. c) At least partially melting the weld ridge of the flange to form a weld joint between the flange and the partition, wherein the weld joint is at least partially formed of the material of the weld ridge. d) Arrange at least one compressible sealing module within the frame. e) Laying cables, conduits, or blind plugs within the sealed module, and f) Arrange a compression unit in the frame and compress the at least one sealing module through the compression unit.

[0018] The frame according to certain embodiments can be used with a welding fixture during the mounting of the frame to the partition and during welding of the frame to the partition. The frame can be used with conventional welded frames. The frame according to certain embodiments can also be used with the welding fixture disclosed herein, wherein the welding fixture disclosed herein is arranged to engage an inclined first surface of the frame without protruding beyond the outer surface of the frame wall. Therefore, a welding fixture for mounting a frame in a partition opening is also disclosed herein, wherein the welding fixture includes a first clamping element, a second clamping element, and an axially extending compression device that movably connects the first clamping element and the second clamping element for clamping opposing first and second surfaces of the frame between the first clamping element and the second clamping element, wherein the first clamping element has first and second engagement surfaces for engaging the first surface of the frame, wherein the first and second engagement surfaces are inclined toward the second clamping element in a radially outward direction. The first and second engagement surfaces of the first clamping element are inclined to prevent movement and deformation of the frame in the radially outward direction, while also preventing movement and deformation of the frame in the axial direction. Therefore, this welding fixture prevents or reduces shape and dimensional changes of the frame in both radial and axial directions without requiring the external parts of the frame to be joined on the rear and / or front sides, which could otherwise hinder the welding process. The inclination of the first and second surfaces of the first fixture element allows for frame-to-partition welding to be facilitated on at least one side of the partition on the same side as the first fixture element. Preventing frame deformation improves the sealing performance of a through-partition system for guiding cables and pipes through the partition, wherein the through-partition system includes a frame and sealing modules disposed in through openings in the frame, along with compression devices for compressing the sealing modules in which cables or pipes are disposed. Furthermore, facilitating welding on one or both sides of the frame produces a more robust installation and can improve the strength and sealing performance of the installation or through-partition system.

[0019] This document also discloses the combination of welded structures and frames. It further discloses the use of welding fixtures for welding frames to partitions. It also discloses methods for welding frames to partitions while they are connected to the welding fixtures. Finally, it discloses methods for providing a partition-passing system for guiding cables and / or pipes through partitions, including the steps of connecting the frame to the welding fixtures while simultaneously welding the frame to the partition.

Detailed Implementation

[0022] refer to Figure 1 The diagram schematically illustrates a partition-passing system 10, according to an example, for allowing at least one cable 11 and / or at least one conduit to pass through a partition. The partition-passing system 10 is arranged to allow one or more cables 11 and / or conduits to pass through a partition in the form of a wall, floor, roof, or ceiling. The partition is in... Figure 1 The partition 10 is indicated by dashed lines and reference numeral 21. For example, the partition system 10 is arranged to allow cables 11 (e.g., cables for electricity, communications, computers, etc.) or conduits for various gases or liquids (e.g., water, compressed air, hydraulic oil, cooking gas, or other types of liquids or gases) to pass through. The cables and / or conduits pass through the partition system 10 axially. The partition system 10 is arranged at a through opening in the partition 21 and attached to the partition, for example, by a fastening device such as a welded joint 22. For example, the partition 21 is made of metal, such as steel, aluminum, or other suitable metal. Alternatively, the partition 21 is made of composite materials, including plastic or metal materials, wherein the partition system 10 can be attached to the partition 22 by welding.

[0023] The perforation system 10 includes one or more sealing modules 12, a compression unit 13, optional one or more partition plates 14, and a frame 15 for receiving the sealing modules 12, the compression unit 13, and (if applicable) the partition plates 14. The sealing modules 12 can be arranged in different sizes, and multiple different sealing modules 12 can be arranged in different configurations, such as... Figure 1 As shown. For example, the sealing module 12, the partition plate 14, and the compression unit 13 are of conventional type. For example, the sealing module 12 is resilient and includes two opposing module halves 16, wherein each module half 16 includes a plurality of optional peelable tabs 17 placed in a semi-cylindrical groove 18, as... Figure 2 As shown. Optionally, an appropriate number of peelable tabs 17 are removed to adapt the sealing module 16 to the diameter of the cable or conduit, wherein the cable 11 or conduit is placed in the module half 16, and the sealing module 13 is formed by placing two module halves 16 one above the other. The module half 16 also includes outer surfaces for abutting against the frame 15, the partition plate 14, and / or adjacent sealing modules 12. The sealing module 12 is elastic, for example made of natural or synthetic rubber, such as EPDM rubber (optionally with additional filler), or TPE.

[0024] For example, the compression unit 13 is a conventional wedge comprising multiple wedge elements (e.g., four wedge elements) operated by one or more compression screws 19. The compression screws 19 are, for example, arranged to move the compression unit from a non-compressed position to a compressed position, in which the compression unit 13 expands radially toward and / or away from the sealing module 12 to press against the sealing module 12 and optionally also against the frame 15. Optionally, the side of the perforation system 10 where the compression screws 19 can be operated (e.g., the side where the screw heads are arranged) is the front side of the perforation system 10.

[0025] according to Figure 1 The frame 15 is arranged to receive a plurality of compressible sealing modules 12 for holding cables 11 or pipes. Figure 1The two sealing modules 12 are shown as having cross-sections of cables 11 or conduits therein, and it should be understood that the cables 11 or conduits are continuous. It should also be understood that if no cables 11 or conduits are arranged therein, the sealing module 12 may be provided with conventional blind plugs 20.

[0026] The partition plate 14 is arranged to prevent axial displacement of the sealing modules 12. The partition plate 14 is arranged between the sealing modules 12, for example between rows of sealing modules, or between the sealing modules 12 or rows of sealing modules and the frame 15, and is arranged to abut against the front and rear sides of the frame 15 to prevent axial displacement. For example, the partition plate 14 is arranged horizontally.

[0027] refer to Figure 3 A frame 15 is shown according to one embodiment. The frame 15 is used, for example, in the perforation system 10 as described above. The frame 15 includes a through opening extending axially for receiving, as referenced above. Figure 1 The sealing module 12, compression unit 13, and optional partition plate 14 are described. In the illustrated embodiment, the frame 15 has a generally rectangular shape, optionally with rounded corners, and a generally rectangular through opening. Therefore, the frame 15 has four interconnected walls, wherein the first and third walls are arranged parallel to each other and interconnected by second and fourth walls arranged parallel to each other. Alternatively, the frame 15 has another shape, such as a circle, wherein the frame 15 can be considered to have a single frame wall or a number of frame walls other than four.

[0028] Frame 15 has a first surface 23 and a second surface 24. Figure 3 In some embodiments, the first surface and the second surfaces 23, 24 form the rear and front sides of the frame 15. For example, the first surface 23 forms the rear side of the frame 15, while the second surface 24 forms the front side of the frame 15. The front side of the frame 15 may correspond to the front side of the perforation system 10.

[0029] Figure 3 The frame 15 in the embodiment includes a flange 25 for abutting against the partition 21. The flange 25 is arranged as follows: Figure 4 As shown, it is welded to partition 21. Figure 4 In this configuration, flange 25 is connected to partition 21 via welded joint 22. Therefore, flange 25 projects radially outward from the outer surface of the frame wall. For example, the inner surface of frame 15 is generally flat and may be smooth or rough. Flange 25 is made of, for example, the same material as the rest of frame 15, such as metal. For example, the frame wall and flange 25 are formed as a single integral piece. In the illustrated embodiment, flange 25 extends continuously around the entire perimeter of frame 15. Alternatively, flange 25 may extend only along the outer sides of two opposing frame walls, or extend incrementally along one or more frame walls.

[0030] Flange 25 includes a radially extending surface 26 for engaging partition 21. In the illustrated embodiment, the radially extending surface 26 of flange 25 faces a direction opposite to the second surface 24 of frame 15. Alternatively, the radially extending surface 26 of flange 25 faces a direction opposite to the first surface 23 of frame 15. For example, the radially extending surface 26 extends radially. For example, the radially extending surface 26 of flange 25 extends in a radial plane, i.e., perpendicular to the axial direction.

[0031] Flange 25 has an inclined surface 27 opposite to the radially extending surface 26. Flange 25 also includes a weld ridge 28 for at least partially melting during welding to at least partially form the material of the weld joint 22. Therefore, the weld ridge 28 is arranged to provide at least some material to the weld joint 22. For example, the weld ridge 28 forms all the material of the weld joint 22. Alternatively, the weld ridge 28 forms a portion of the material of the weld joint 22, wherein additional welding material can be added along with the material of the weld ridge 28 during welding. Optionally, the additional welding material can be added in a conventional manner, such as by filler metal, consumable welding wire electrodes, or similar methods. The weld ridge 28 forms the radially outward end of flange 25. For example, the weld ridge 28 extends from the inclined surface 27 to the radially extending surface 26. For example, the interior portion of the weld ridge 28 is arranged to abut against partition 21. For example, the inner portion of the weld ridge 28 extends radially and is optionally aligned with the radial extension portion 26 such that the inner portion of the weld ridge 28 abuts against the partition 21 together with the radial extension surface 26 when mounted to the partition 21.

[0032] In the illustrated embodiment, the inclined surface 27 extends from the outside of the frame wall to the weld ridge 28. For example, the inclined surface 27 extends from the weld ridge 28 toward the second surface 24 of the frame 15, wherein the inclined surface 27 tapers toward the second surface 24. For example, the inclined surface 27 then terminates at a distance from the second surface 24. Alternatively, the inclined surface 27 extends all the way to the second surface 24. The inclined surface 27 is arranged at an angle of 10 to 60 degrees (e.g., 10 to 45 degrees) relative to the axial direction. The inclined surface 27 is arranged to stabilize the flange 25 and prevent the portion of the flange 25 other than the weld ridge 28 from melting. The inclined surface 27 also stabilizes the frame and prevents its deformation, for example, during welding. Therefore, the inclined surface 27 is arranged to prevent undesirable melting of the radially extending surface 26 and / or to prevent deformation of the frame 15.

[0033] In the illustrated embodiment, the first surface 23 of the frame 15 is inclined toward the second surface 24 in a radially outward direction. The inclination of the first surface 23 is optional. Therefore, in the radially outward direction, the first surface 23 is inclined axially inward. The first surface 23 is at an angle relative to the radial plane. Arrangement. The first surface 23 extends from the inner edge of the frame 15 toward its outer edge, for example, all the way to the outer edge. For example, the frame 15 is formed such that the axial depth from the first surface 23 to the second surface 24 is less outside the frame 15 than inside the frame 15. Therefore, the frame 15 is formed such that the outer axial depth is less than the inner axial depth. For example, the first surface 23 is at an angle of at least 2 degrees or at least 5 degrees. Arrangement. For example, angles. The maximum is 45 degrees, 30 degrees, or 20 degrees.

[0034] For example, the second surface 24 extends in a radial plane as shown. For example, the second surface 24 extends continuously from the inner edge of the frame wall to the outer edge of the frame wall in the radial plane. Alternatively, the second surface 24 is inclined in a manner similar to the first surface 23 described above. For example, the first and / or second surfaces are formed as described, inclined radially outward and axially inward.

[0035] exist Figure 4 In this embodiment, the frame 15 is connected to the partition 21 via a weld joint 22 between the flange 25 on the first side of the partition 21 and the partition 21, and an optional corner weld joint 29 on the second side of the partition 21 opposite to the first side. The weld joint 22 and the corner weld joint 29 are located on opposite sides of the partition 21. Therefore, the corner weld joint 29 connects the partition 21 and the exterior of the frame 15 on the side of the partition 21 opposite to the flange 25. The corner weld joint 29 connects the partition 21 and the exterior of the frame 15 on the same side of the partition 21 as the first surface 23 (i.e., the side opposite to the flange 25 and the second surface 23). Therefore, in Figure 4 In one embodiment, the frame 15 is connected to the partition 21 via both welded joint 22 and fillet weld joint 29. Alternatively, the frame 15 is connected to the partition 21 via either welded joint 22 or fillet weld joint 29 only.

[0036] refer to Figure 5 The diagram schematically shows a frame 15 according to another embodiment, wherein the frame 15 is connected to the partition 21 by welded joints 22 and corner welds 29. Figure 5 The framework 15 includes the above references Figure 4 The flange 25 is described, but does not include the inclined first surface 23. Instead, the first surface 23 extends in a radial plane. For example, the first surface 23 is arranged parallel to the second surface 24. Alternatively, the second surface 24 is inclined.

[0037] refer to Figures 6 to 8 , Figure 3 and Figure 4 The frame 15 is connected to the welding fixture 30. However, it should be understood that the welding fixture 30 can be connected in the same manner. Figure 5The frame 15 and other appropriately shaped frames are also present. A welding fixture 30 is arranged for use during the welding process for welding the frame 15 to the partition 21. For example, the welding fixture 30 is arranged for use before, during, and after the welding process to mount the frame 15 into an opening in the partition so as to maintain the dimensional properties of the frame 15 during welding. The welding process may involve high temperatures that affect the material of the frame 15, which may cause undesirable deformation and dimensional changes in the frame 15, and the welding fixture 30 can prevent these deformations and dimensional changes.

[0038] The welding fixture 30 includes a first clamping element 31, a second clamping element 32, and an axially extending compression device 33 that movably connects the first clamping element 31 and the second clamping element 32 for clamping opposing first surfaces 23 and second surfaces 24 of the frame 15 between the first clamping element 31 and the second clamping element 32. The first clamping element 31 extends from one frame wall to the opposing frame wall for holding the frame 15 at the first surface 23 of the frame 15 at the opposing frame wall. For example, the first clamping element 31 is arranged as a plate extending between the opposing frame walls. The second clamping element 32 is, for example, arranged as a plate extending between the opposing frame walls for holding the frame 15 at the second surface 24 of the frame 15 at the opposing frame wall.

[0039] Compression device 33 is arranged for axially moving the first and second clamping elements 31, 32 toward and away from each other. For example, compression device 33 includes a screw, such as a single screw, movably connected to the first and second clamping elements 31, 32 in a conventional manner. The screw is threaded to at least one of the first and second clamping elements 31, 32 for moving the first and second clamping elements 31, 32 relative to each other by turning the screw. Optionally, compression device 33 also includes a washer disposed between the screw head and one of the first and second clamping elements 31, 32. Compression device 33 is, for example, disposed at the center of the first and second clamping elements 31, 32. For example, compression device 33 is arranged to pass through a central hole in the first clamping element 31 and a central hole in the second clamping element 32.

[0040] The first clamping element 31 has first and second mating surfaces 34, 35 for engaging the first surface 23 of the frame 15. The second clamping element 32 has third and fourth mating surfaces 36, 37 for engaging the second surface 24 of the frame 15. The first and second mating surfaces 34, 35 are arranged to mate with the third and fourth mating surfaces 36, 37 to clamp the frame 15 between them. Thus, the first mating surface 34 is arranged substantially opposite to the third mating surface 36, and the second mating surface 35 is arranged substantially opposite to the fourth mating surface 37. Alternatively, the first mating surface 34 is arranged in a similar manner to the second mating surface 35, and the third mating surface 36 is similar to the fourth mating surface 36. According to one embodiment, the third and fourth mating surfaces 36, 37 are arranged in the same manner as the first and second mating surfaces 34, 35.

[0041] The first and second mating surfaces 34 and 35 are arranged to be inclined toward the second clamping element 32 in a radially outward direction. Therefore, the first and second mating surfaces 34 and 35 are at an angle relative to the radial plane. Arrangement. The first and second mating surfaces 34 and 35 are arranged to mate with the inclined first surface 23 of the frame 15 to prevent displacement and deformation of the frame 15 in the radially outward direction. Simultaneously, the first and second mating surfaces 34 and 35 mate with the second clamping element 31 to prevent displacement and deformation of the frame 15 in the axial direction. For example, angle. The angle corresponding to the first surface 23 of frame 15 Alternatively, angle Greater than the angle For example, angle. It must be at least 2 degrees or at least 5 degrees, and less than 45 degrees or less than 30 degrees.

[0042] In the illustrated embodiment, the third and fourth mating surfaces 36 and 37 extend in a radial plane. Therefore, the outer ends of the first and second mating surfaces 34 and 35 are arranged such that their axial distance from the second clamping element 32 is less than the corresponding axial distance at the inner ends of the first and second mating surfaces 34 and 35. The outer end of the first mating surface 34 is arranged such that its axial distance from the third mating surface 36 is less than the axial distance between the inner end of the first mating surface 34 and the third mating surface 36, wherein the outer end of the second mating surface 35 is arranged such that its axial distance from the fourth mating surface 37 is less than the axial distance between the inner end of the second mating surface 34 and the fourth mating surface 37.

[0043] The first clamping element 31 is arranged such that the outer side of the frame 15 is unobstructed to facilitate welding the frame 15 to the partition 21. In the illustrated embodiment, the first and second mating surfaces 34, 35 extend to the opposite outer edges of the first clamping element 31 and form the outer periphery of the first clamping element 31, wherein the first clamping element 31 is adapted not to surround the axially extending outer surface of the frame 15.

[0044] The first and second mating surfaces 31 and 32 are connected to the inner support surfaces 38 and 39 for supporting the inner surface of the frame 15 and preventing displacement and deformation of the frame 15 in the radially inward direction. For example, the inner support surfaces 38 and 39 extend substantially in an axial plane and optionally taper towards the second clamping element 32. Thus, the inner support surfaces 38 and 39, as well as the first and second mating surfaces 34 and 35, are arranged to surround the inner edge of the frame 15.

[0045] The second clamping element 32 includes inner support surfaces 40, 41 for supporting opposing inner axial surfaces of the frame 15. The inner support surfaces 40, 41 extend in a plane parallel to the axial direction. The second clamping element 32 also includes outer support surfaces 42, 43 for supporting opposing outer axial surfaces of the frame 15. The outer support surfaces 42, 43 extend in a plane parallel to the axial direction. The outer support surfaces 42, 43 are arranged opposite to the inner support surfaces 40, 41 of the second clamping element 31. In the illustrated embodiment, the inner support surfaces 40, 41, the outer support surfaces 42, 43, and the third and fourth engagement surfaces 36, 37 of the second clamping element 32 are formed by first and second recesses of the second clamping element 32, wherein the first and second recesses are arranged to receive and surround portions of the second surface 24 at the opposing frame wall. Therefore, the second clamping element 32 can be arranged to extend over the second surface 24 of the frame 15 to engage the axial outer surfaces of the opposing frame wall, wherein the first clamping element 31 stops before reaching the corresponding outer surface. For example, the radial width of the first clamping element 31 is smaller than the corresponding radial width of the second clamping element 32.

[0046] refer to Figures 10 to 12 A welding fixture 30 connected to a frame 15b according to another embodiment of the present invention is shown. Figure 13 In the diagram, a portion of frame 15b is schematically shown in cross-section. Figures 10 to 12 In the embodiments described above, the welding fixture 30 optionally has a flange 25, and therefore includes angled... The first and second mating surfaces 34 and 35 are arranged. Figures 10 to 13The frame 15b differs from the frame 15 described above in that the first surface 23 does not form either the front or rear side of the frame 15b, but is arranged in at least one elongated and radially extending inner slot 44 of the frame 15b, located between the front and rear sides. For example, the frame 15b includes two slots 44, each located in each of two opposing and parallel frame walls. For example, the slots 44 extend from one inner end of the two opposing frame walls to their opposite ends, wherein the slots 44 are arranged in parallel and aligned axially. Alternatively, a single slot 44 extends continuously around the inner periphery of the frame 15b, i.e., along all four frame walls. For example, the slot or slots 44 are arranged away from both the front and rear sides of the frame 15, for example, in at least the axially central portion of the opposing frame walls. For example, the slot or slots 44 are elongated and extend in the radial direction. The slots or slots 44 are arranged to receive radially projecting outer edge portions of a first clamping element 31 having first and second mating surfaces 34, 35, such that the first and second mating surfaces 34, 35 engage the first surface 23 of the slots or slots 44. After mounting the frame 15b, the slots or slots 44 may be arranged to receive protruding portions of one or more partition plates 14 of the perforation system 10.
