Description

Technical Field

[0001] This utility model relates to the field of flat steel baffle heat exchanger manufacturing technology, and in particular to a tooling for manufacturing flat steel baffles. Background Technology

[0002] A baffle heat exchanger is a type of heat exchanger with excellent vibration resistance. Its characteristic feature is the replacement of the baffle rods (round rods) with flat steel support bars. These support bars, together with the support ring, form an anti-vibration grid. The heat exchange tubes are typically held tightly together by two sets of flat steel bars, resulting in line contact between the heat exchange tubes and the baffles, which significantly suppresses tube vibration. Generally, the two sets of flat steel bars in a baffle grid are interlocked. However, in some operating conditions, the two sets of flat steel bars are not interlocked but arranged parallel to each other, increasing the height of the baffle grid. Due to the low positioning accuracy of the two sets of flat steel bars and insufficient rigidity of the baffle ring, the baffle grid deforms significantly during welding, making it difficult for the heat exchange tubes to pass through and easily damaging the surface of the heat exchange tubes. Forced assembly can also damage the flat steel bars, thus affecting heat exchange performance and vibration resistance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a tooling for manufacturing flat steel baffles, which is applied to the manufacturing of flat steel baffle heat exchangers. It solves the problems of low manufacturing precision and difficulty in tube insertion of flat steel baffles, and provides an optimized process solution for the manufacturing of baffle heat exchangers.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tooling for manufacturing flat steel baffles, including a tooling plate groove and a slotted grid plate used in conjunction;

[0005] The tooling plate groove is a circular plate with an outer annular groove, a welding groove line, and a pipe hole formed thereon. The welding groove line and the pipe hole are located within the outer annular groove. The slotted grid plate can be embedded in the welding groove line or parallel to the welding groove line.

[0006] The weld groove line includes a plurality of first groove lines and second groove lines, wherein the first groove lines and second groove lines intersect each other, and the plurality of first groove lines and second groove lines are parallel to each other.

[0007] The pipe hole includes a first pipe hole and a second pipe hole. The first pipe hole is opened at the intersection of the first groove line and the second groove line, close to the first groove line and the second groove line. The second pipe hole is opened on the tooling plate groove, corresponding to the position of the outermost heat exchange tube of the flat steel baffle.

[0008] The slotted grating plate includes an upper slotted grating plate and a lower slotted grating plate. Several limiting grooves are provided on the upper slotted grating plate and the lower slotted grating plate, and flat steel bars can be inserted into the limiting grooves.

[0009] Furthermore, the width of the welded groove line is 0.1 mm thicker than the slotted grating plate, and the depth of the welded groove line is 3 mm.

[0010] Furthermore, the width of the outer ring groove is 0.1 mm thicker than the thickness of the baffle ring.

[0011] Furthermore, the thickness of the slotted grating plate is the same as the thickness of the flat steel bar.

[0012] Furthermore, the plurality of limiting grooves disposed on the upper slotted grid plate or the lower slotted grid plate are symmetrically distributed on the upper slotted grid plate or the lower slotted grid plate.

[0013] Compared with the prior art, the beneficial effects of this utility model include:

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Figure 1 The schematic diagram shows the planar structure of the tooling for fabricating flat steel baffles. Figure 2 The schematic diagram shows a cross-sectional view of a tooling for fabricating flat steel baffles, such as... Figure 1-2 As shown, it includes a tooling plate groove 1 and a slotted grid plate for use.

[0024] The aforementioned tooling plate groove 1 is a circular plate. An outer ring groove 2, welding groove lines 3, and pipe holes are formed on the tooling plate groove 1. The welding groove lines 3 and pipe holes are all located within the outer ring groove 2. The slotted grid plate can be embedded in the aforementioned welding groove lines 3 or remain parallel to them. The welding groove lines 3 consist of several first groove lines 31 and second groove lines 32. The first groove lines 31 intersect with the second groove lines 32, and the first groove lines 31 are parallel to each other, as are the second groove lines 32. The pipe holes include first pipe holes 4 and second pipe holes 5. The first pipe holes 4 are formed near the intersection of the first groove lines 31 and the second groove lines 32, while the second pipe holes 5 are formed on the tooling plate groove 1 and correspond to the outermost heat exchange tubes of the flat steel baffle.

[0025] The slotted grating includes an upper slotted grating 6 and a lower slotted grating 7. Several limiting grooves are provided on both the upper slotted grating 6 and the lower slotted grating 7. Flat steel bars 8 can be inserted into the aforementioned limiting grooves. The limiting grooves provided on the upper slotted grating 6 or the lower slotted grating 7 are symmetrically distributed on the upper slotted grating 6 or the lower slotted grating 7. That is, the only difference between the upper slotted grating 6 and the lower slotted grating 7 is the position of the aforementioned limiting grooves.

[0026] The width of the aforementioned welded groove line 3 is 0.1 mm thicker than the slotted grating plate, and the depth of the welded groove line 3 is 3 mm, so that the slotted grating plate can be vertically fixed in the welded groove line 3 on the tooling plate groove 1; the width of the aforementioned outer ring groove 2 is 0.1 mm thicker than the thickness of the baffle ring, so as to facilitate the arrangement of the baffle ring; the thickness of the slotted grating plate is the same as the thickness of the flat steel bar 8, so that in the flat steel baffle, after the slotted grating plate completes the auxiliary assembly of the flat steel bar 8, it can bear the function of the flat steel bar 8 and separate the heat exchange tubes located in the flat steel baffle.

[0027] The following is a detailed explanation of the application process of the tooling for manufacturing flat steel baffles.

[0028] like Figure 3-4 As shown, the baffle is composed of an upper slotted grating plate 6, a lower slotted grating plate 7, an upper flat steel bar 8, a lower flat steel bar 8, and a baffle ring. First, the upper slotted grating plate 6 is inserted into the welding groove line 3 on the tooling plate groove 1, with the side of the upper slotted grating plate 6 with the limiting groove facing upwards. Then, the lower slotted grating plate 7 is fitted and fixed to the aforementioned upper slotted grating plate 6 by partially using the limiting groove. At this time, the direction of the lower slotted grating plate 7 is parallel to the welding groove line 3 on the tooling plate groove 1, that is, the sides of the upper slotted grating plate 6 and the lower slotted grating plate 7 with the limiting grooves are arranged opposite each other and one of them is embedded into the welding groove line 3 on the tooling plate groove 1. Finally, the upper slotted grating plate 6 and the lower slotted grating plate 7 are welded and fixed.

[0029] At this point, insert the lower flat steel strip 8 into the lower slotted grating plate 7, adjust the verticality of the flat steel strip 8, and extend it to the outer ring groove 2. Weld the flat steel strip 8 to the slotted grating plate. Take the semi-finished baffle plate obtained in the above process out of the tooling plate, and install it onto the welding groove line 3 of the tooling plate with the reverse side facing down. Since the angle and shape of the upper slotted grating plate 6 and the lower slotted grating plate 7 are the same as the shape of the welding groove line 3, it can be directly inserted into the welding groove line 3 after flipping. Insert all the positioning tubes into the tooling plate. Insert the upper flat steel strip 8 into the upper slotted grating plate 6, adjust the verticality of the flat steel strip 8, and extend it to the outer ring groove 2. Try pulling the positioning tubes to ensure that all positioning tubes can be easily inserted into the baffle plate. Weld the flat steel strip 8 to the slotted grating plate. Insert the baffle ring into the outer ring groove 2 of the tooling, adjust the gap between the flat steel strip 8, the grating plate and the baffle ring, and weld them in place. The baffle was tested by using a positioning tube to adjust the position of each component and ensure smooth tube insertion. Finally, the baffle was welded and fixed in place.

[0030] By employing a tooling system for fabricating flat steel baffles, the fabrication process can be completed, ensuring dimensional accuracy of the baffles, minimizing the impact of welding deformation, maintaining consistent dimensions across multiple baffle sets with deviations within controllable ranges, facilitating easy pipe installation, minimizing damage to the heat exchanger tube surface, and reducing equipment and manpower investment in heat exchanger assembly. This is particularly beneficial for improving the fabrication accuracy of non-interlocking flat steel baffles, effectively guaranteeing the installation quality of the baffle heat exchanger. For baffle heat exchangers with different diameters and tube sizes, application can be achieved simply by adjusting the design parameters.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
