This structure avoids problems such as local upward protrusion or downward movement, is less prone to warping, is less likely to cause tempering, and has a simple structure and low cost.

[0004] The purpose of this invention is to provide a method for manufacturing a honeycomb structure.

[0005] To achieve the objectives of this invention, the following technical solution is adopted:

[0006] According to one aspect of the present invention, a honeycomb structure is provided. The honeycomb structure includes a metal strip comprising a plurality of planar segments and a plurality of corrugated segments, the metal strip (1) forming the honeycomb structure by coiling.

[0007] According to one embodiment of the present invention, the metal strip is coiled to form a plurality of coils, the coils including two types, one of which is a first coil formed by coiling the planar section once, and the other is a second coil formed by coiling the corrugated section once.

[0040] like Figures 1 to 6 As shown, Figure 1 A schematic diagram of the honeycomb structure provided by the present invention is shown. Figure 2 Shown Figure 1 Enlarged view of point A in the middle. Figure 3 A schematic diagram of one morphology of the honeycomb structure provided by the present invention is shown.

Figure 5 A schematic diagram of a honeycomb structure with ring-shaped bodies provided by the present invention is shown. Figure 6 A schematic diagram of the method for manufacturing a honeycomb structure provided by the present invention is shown.

[0041] An embodiment of the present invention provides a honeycomb structure, which includes: a metal strip 1, the metal strip 1 including a plurality of planar segments 11 and a plurality of corrugated segments 12, the planar segments 11 and the corrugated segments 12 being alternately connected, and the metal strip 1 forming a honeycomb structure by coiling.

[0042] In this application, a single-layer metal strip with a planar section 11 and a corrugated section 12 is used to form a regular corrugated shape by rolling or stamping.

[0043] In the first scenario, the planar segment 11 and the corrugated segment 12 are alternately connected. The initial end of the metal strip 1 can be a planar segment 11, with the end of the planar segment 11 connecting to the initial end of the corrugated segment 12. The initial end of the corrugated segment 12 connects to the initial end of the next planar segment 11, and the end of the next planar segment 11 connects to the initial end of the next corrugated segment 12, and so on. Alternatively, the initial end of the metal strip 1 can also be a corrugated segment 12, followed by a planar segment 11, as long as the planar segment 11 and corrugated segment 12 are alternately connected. It should be noted that in this application, the initial end of the metal strip 1 is the side where the metal strip 1 is coiled, and the end corresponds to the initial end.

[0044] The second scenario is that the planar segment 11 and the corrugated segment 12 are not alternately connected. For example, the initial end of the metal strip 1 could be a planar segment 11, the second a corrugated segment 12, the third a corrugated segment 12, the fourth a planar segment 11, and the fifth a planar segment 11. This scenario applies to a coil 100 with one planar segment 11 and one corrugated segment 12. Alternatively, the initial end of the metal strip 1 could be a planar segment 11, the second a corrugated segment 12, the third a planar segment 11, the fourth a corrugated segment 12, the fifth a corrugated segment 12, the sixth a planar segment 11, the seventh a corrugated segment 12, the eighth a planar segment 11, the ninth a planar segment 11, and so on. This scenario can be referenced. Figure 2 Each coil 100 has two planar segments 11 and two corrugated segments 12. Of course, when there are multiple planar segments 11 and multiple corrugated segments 12 on the coil 100, the connection between two adjacent coils 100 is not an alternating connection of planar segments 11 and corrugated segments 12, but rather two identical shapes, either both corrugated segments 12 or both planar segments 11.

[0045] pass Figure 1-5 As can be seen from the honeycomb structure shown, the honeycomb structure also has multiple air outlet rings. In this application, the corrugated section 12 and the planar section 11 are used in cooperation to make the upper wave of the corrugated section 12 serve as the air outlet channel. Multiple corrugated sections 12 are evenly distributed along the honeycomb structure, which not only ensures uniform air outlet, but also plays a role in stabilizing and distributing the airflow and reducing the generation of flue gas.

[0046] The metal strip 1 is coiled multiple times to form a honeycomb structure. After the metal strip 1 is coiled, multiple coiled rings 100 are formed. Therefore, the honeycomb structure of this application is composed of multiple mutually constrained coiled rings 100. In addition, the planar segment 11 and the corrugated segment 12 are mutually constrained, so there will be no problem of local upward protrusion or downward movement. The honeycomb structure is not easy to warp, not easy to cause tempering, and has a simple structure and low cost.

[0047] In addition, the cross-section of the honeycomb can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, and dodecagon.

[0048] In a preferred embodiment of the present invention, the metal strip 1 is coiled to form a plurality of coils 100. The coils 100 include two types, one of which is a first coil 100a formed by coiling a planar section 11, and the other is a second coil 100b formed by coiling a corrugated section 12.

[0049] The first disc winding 100a and the second disc winding 100b are alternately arranged.

[0050] Figure 1As shown, this application can form a first coil 100a by coiling the planar segment 11 once, and a second coil 100b by coiling the corrugated segment 12 once. The second coil 100b is arranged around the outer ring of the first coil 100a, and the first coil 100a is arranged around the outer ring of the second coil 100b. This process is repeated, with multiple first coils 100a and second coils 100b alternately arranged to form a honeycomb structure. That is, each coil 100 in the honeycomb structure is a separate planar segment 11 or corrugated segment 12.

[0051] The innermost layer of the honeycomb can be either the first coil (100a) or the second coil (100b). Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after one turn, it forms a first coil 100a. Then, the corrugated segment 12 is coiled around the outer periphery of the first coil 100a to form a second coil 100b. Then, the next planar segment 11 is coiled around the outer periphery of the second coil 100b, and so on, to form a honeycomb structure.

[0052] Furthermore, the planar segment 11 can be coiled multiple times as needed; the length of the planar segment 11 and the number of coils after coiling only need to be set before pressing. The lengths of different planar segments 11 and corrugated segments 12 can be calculated based on preset parameters such as the inner and outer diameters of the honeycomb body, the thickness of the metal strip 1, and the wave height of the corrugated segment 12.

[0053] The first disc winding 100a and the second disc winding 100b of this application are alternately arranged. The multiple waves on the corrugated section 12 can divide the space of two adjacent first disc windings 100a into multiple uniform air outlet channels, which can play the role of stabilizing and distributing the airflow.

[0054] In a preferred embodiment of the present invention, the metal strip 1 is coiled to form a plurality of coils 100. Each coil 100 includes a planar segment 11 and a corrugated segment 12. The outer side of the corrugated segment 12 is the planar segment 11 of the adjacent coil 100, and the outer side of the planar segment 11 is the corrugated segment 12 of the adjacent coil 100.

[0055] In a preferred embodiment of the present invention, each coil 100 has at least one planar segment 11 and one corrugated segment 12.

[0056] like Figure 3-4 As shown, the metal strip 1 is coiled to form multiple coils 100. Each coil 100 can simultaneously include a planar segment 11 and a corrugated segment 12, for example... Figure 3 As shown, each coil 100 has one planar segment 11 and one corrugated segment 12, but it can also be as follows: Figure 4As shown, each coil 100 has two planar segments 11 and two corrugated segments 12. Of course, the number of planar segments 11 and corrugated segments 12 on each coil 100 can also be three, four, five, six, eight, nine, ten, twelve or even more. This application does not impose any restrictions here.

[0057] As long as the outer ring of the planar segment 11 on the adjacent coil 100 is a corrugated segment 12, and the outer ring of the corrugated segment 12 is a planar segment 11, that is, the planar segment 11 and the corrugated segment 12 are alternately arranged from the inner ring to the outer ring, it is ensured that the air outlets are evenly distributed on the air outlet surface, ensuring uniform air outlet. Here, the air outlets are the segments on the corrugated segment 12, and each segment can serve as an air outlet, ensuring uniform air outlet, stable flame, and less smoke.

[0058] In a preferred embodiment of the present invention, an annular body 2 is further included, wherein a metal strip 1 is coiled around the outer periphery of the annular body 2.

[0059] like Figure 5 As shown, the initial end of the planar segment 11 can be connected to the outer periphery of the annular body 2, that is, the annular body 2 can be wrapped with a circle or a section of the planar segment 11. Alternatively, the corrugated segment 1212 can be directly coiled around the outer periphery of the annular body 2, which can increase the overall strength of the entire metal honeycomb.

[0060] In a preferred embodiment of the present invention, the corrugated section 12 includes a plurality of crests 121 and a plurality of troughs 122; a transition section 101 is provided between two adjacent coils 100.

[0061] In such Figure 1-5 As shown, the corrugated segment 12 includes multiple peaks 121 and multiple troughs 122. The peak near the beginning of the corrugated segment 12 is the first peak 1210, the trough near the beginning of the corrugated segment 12 is the first trough 1220, the peak near the end of the corrugated segment 12 is the Nth peak 1211, and the trough near the end of the corrugated segment 12 is the Nth trough 1221.

[0062] In such Figure 1-5 In the honeycomb structure shown, a portion of the transition section 101 is connected between the first peak 1210 and the Nth peak 1211 on the same corrugated section 12, while the remaining portion of the transition section 101 is connected between the first trough 1220 and the Nth trough 1221. An irregular quadrilateral is formed by connecting the adjacent first coil 100a and second coil 100b through two transition sections, the first peak 1210 and the Nth peak 1211, and the first trough 1220 and the Nth trough 1221. The quadrilateral can be used to coil the corrugated section 12 into a whole, and can also tightly connect the corrugated section 12 and the planar section 11 to form a whole, thus avoiding the problem of the honeycomb structure lifting.

[0063] exist Figure 3-4 In the honeycomb structure shown, a transition section 101 is provided between two adjacent coiled rings 100. Because the inner side of the coiled flat section 11 is close to the outer periphery of the corrugated section 12 located in the inner ring, the first coiled ring 100 located in the inner ring has a corrugated section 12 at its initial end and a flat section 11 at its end. When the flat section 11 is coiled to the outer ring, it needs to coil from the trough 122 of the corrugated section 12 located at the initial end to its crest 121, and continue to coil to form a second coiled ring 100 by abutting against the outer periphery of the corrugated section 12. Generally, the initial end of the second coil 100 is a flat segment 11, and the end is a corrugated segment 12. When the corrugated segment 12 at the end of the coil 100 is coiled into the third coil 100, the transition segment 101 will connect from the Nth wave peak 1211 of the second corrugated segment 12 at the end of the second coil 100 to the first wave trough 1220 of the corrugated segment 12 at the initial end of the third coil 100. At the same time, the inner side of the transition segment 101 will abut against the first wave peak 1210 of the second corrugated segment 12 at the initial end of the second coil 100. This cycle is repeated to form a tightly connected honeycomb structure, avoiding the problem of the honeycomb structure lifting caused by local upward protrusion or downward movement.

[0064] In a preferred embodiment of the present invention, the cross-section of the corrugated segment 12 is a triangular wave with a wavelength of 0.2 mm to 3 mm and a wave height of 0.1 mm to 2 mm.

[0065] like Figure 1-5 As shown, whether the corrugated segments 12 form a single coil 100 or are regular-shaped bands, each wave is triangular in shape, and adjacent waves are the same size and shape, exhibiting central symmetry. This results in an aesthetically pleasing honeycomb structure with simple manufacturing process and uniform venting. Generally speaking, the wave sizes of the corrugated segments 12 on the same venting ring are consistent.

[0066] Of course, the wave size on the corrugated section 12 can also be different, especially the corrugated section 12 located on the inner ring and the corrugated section 12 located on its outer ring. The wave size can be different. For example, the vent hole on the outer ring can be larger than the vent hole on the inner ring. In some cases, the vent hole on the inner ring can be larger than the vent hole on the outer ring to increase the central firepower.

[0067] An embodiment of the present invention provides a method for manufacturing a honeycomb structure, the method comprising:

[0068] Select a thin metal strip 1 and determine the basic parameters of the prefabricated honeycomb structure;

[0069] Calculate the lengths of planar segment 11 and corrugated segment 12 based on the basic parameters of the honeycomb structure;

[0070] Based on the lengths of the planar segment 11 and the corrugated segment 12, multiple planar segments 11 and multiple corrugated segments 12 are pressed onto the metal strip 1; then the metal strip 1 is coiled multiple times to form a honeycomb structure.

[0071] The basic parameters of the honeycomb structure can be: the inner diameter of the honeycomb structure is a, the circumference of the coil 100 is S, and the size of the vent is given. Since the vent in this application corresponds to each wave of the corrugated segment 12, the size of the vent is the wave height of the corrugated segment 12 as d and the wavelength as c. Furthermore, it is assumed that the thickness of the metal strip 1 is b, and the circumference of the i-th coil 100 is S. i ,but:

[0072] S i =π[a+(i-1)(b+d)]. Where i represents the height from the inside out, and the wave height is the height from the inside of the wave crest 121 to the lowest point of the wave trough 122, which is the distance from the highest point inside the wave crest 121 to the outer perimeter of the plane segment 11 located inside the wave.

[0073] The pressing method in this application can be rolling, stamping, etc., as long as it can simultaneously form planar segments 11 and corrugated segments 12 on the metal strip 1. In one scenario, the planar segments 11 and corrugated segments 12 are alternately connected. For example, the initial end of the metal strip 1 is a planar segment 11, and the end of the planar segment 11 connects to the initial end of the corrugated segment 12. The initial end of the corrugated segment connects to the initial end of the next planar segment 11, and the end of the next planar segment 11 connects to the initial end of the next corrugated segment 12, and so on. Alternatively, the initial end of the metal strip 1 can be a corrugated segment 12 followed by a planar segment 11, as long as the planar segments 11 and corrugated segments 12 are alternately arranged. It should be noted that in this application, the initial end of the metal strip 1 is the side where the metal strip 1 is coiled, and the end corresponds to the initial end. The second scenario is that the planar segment 11 and the corrugated segment 12 are not alternately connected. For example, the initial end of the metal strip 1 could be a planar segment 11, the second a corrugated segment 12, the third a corrugated segment 12, the fourth a planar segment 11, and the fifth a planar segment 11. This scenario applies to a coil 100 with one planar segment 11 and one corrugated segment 12. Alternatively, the initial end of the metal strip 1 could be a planar segment 11, the second a corrugated segment 12, the third a planar segment 11, the fourth a corrugated segment 12, the fifth a corrugated segment 12, the sixth a planar segment 11, the seventh a corrugated segment 12, the eighth a planar segment 11, the ninth a planar segment 11, and so on. This scenario can be referenced. Figure 2Each coil 100 has two planar segments 11 and two corrugated segments 12. Of course, when there are multiple planar segments 11 and multiple corrugated segments 12 on the coil 100, the connection between two adjacent coils 100 is not an alternating connection of planar segments 11 and corrugated segments 12, but rather two identical shapes, either both corrugated segments 12 or both planar segments 11.

[0074] The metal strip 1 is coiled multiple times by the equipment to form a honeycomb structure. After coiling, the metal strip 1 consists of multiple coiled rings 100. Therefore, the honeycomb structure of this application is composed of multiple mutually constrained coiled rings 100. The planar section 11 and the corrugated section 12 are alternately connected, so that the honeycomb structure will not have the problem of local upward protrusion or downward movement. Moreover, it is not easy to warp or cause tempering. The structure is simple and the cost is low.

[0075] In this application, the corrugated section 12 and the planar section 11 are used in combination so that the upper wave of the corrugated section 12 serves as the air outlet channel. Multiple corrugated sections 12 are evenly distributed along the honeycomb structure, which not only ensures uniform air outlet, but also plays a role in stabilizing and distributing the airflow and reducing the generation of flue gas.

[0076] Furthermore, the cross-section of the honeycomb can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc., and this application does not impose any restrictions on it.

[0077] In a preferred embodiment of the present invention, the planar segment 11 is coiled once to form a first coil 100a, and the corrugated segment 12 is coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b. By alternating multiple first coils 100a and second coils 100b, a honeycomb structure is formed.

[0078] In a preferred embodiment of the present invention, one of the two coils, either the first coil 100a or the second coil 100b, is disposed on the innermost side of the honeycomb.

[0079] Figure 1 As shown, this application can form a first coil 100a by coiling the planar segment 11 once, and a second coil 100b by coiling the corrugated segment 12 once. The second coil 100b is arranged around the outer ring of the first coil 100a, and the first coil 100a is arranged around the outer ring of the second coil 100b. This process is repeated, with multiple first coils 100a and second coils 100b alternately arranged to form a honeycomb structure. That is, each coil 100 in the honeycomb structure is a separate planar segment 11 or corrugated segment 12.

[0080] The innermost layer of the honeycomb can be either the first coil (100a) or the second coil (100b). Figure 1The planar segment 11 is shown as the starting end of the metal strip 1, and after one turn, it forms a first coil 100a. Then, the corrugated segment 12 is coiled around the outer periphery of the first coil 100a to form a second coil 100b. Then, the next planar segment 11 is coiled around the outer periphery of the second coil 100b, and so on, to form a honeycomb structure.

[0081] Furthermore, the planar segment 11 can be coiled multiple times as needed; the length of the planar segment 11 and the number of coils after coiling only need to be set before pressing. The lengths of different planar segments 11 and corrugated segments 12 can be calculated based on preset parameters such as the inner and outer diameters of the honeycomb body, the thickness of the metal strip 1, and the wave height of the corrugated segment 12.

[0082] The first disc winding 100a and the second disc winding 100b of this application are alternately arranged. The multiple waves on the corrugated section 12 can divide the space of two adjacent first disc windings 100a into multiple uniform air outlet channels, which can play the role of stabilizing and distributing the airflow.

[0083] In a preferred embodiment of the present invention, the lengths of the planar segment 11 and the corrugated segment 12 are such that each coil 100 simultaneously has a planar segment 11 and a corrugated segment 12, and the outer side of the corrugated segment 12 is the planar segment 11 of the adjacent coil 100, and the outer side of the planar segment 11 is the corrugated segment 12 of the adjacent coil 100.

[0084] like Figure 3-5 As shown, each coil 100 can consist of one planar segment 11 and one corrugated segment 12, or it can be as follows: Figure 4 As shown, each coil 100 has two planar segments 11 and two corrugated segments 12. Of course, the number of planar segments 11 and corrugated segments 12 on each coil 100 can also be three, four, five, six, eight, nine, ten, twelve or even more. This application does not impose any restrictions here.

[0085] When pressing the metal strip 1, the system only needs to calculate the length of each flat segment 11 and corrugated segment 12 based on the inner and outer diameters of the honeycomb body, the number of flat segments 11 and corrugated segments 12 on each winding loop 100, the thickness of the metal strip 1, the wave height and wavelength of the corrugated segment 12, and the relationship between different inner and outer diameters. Then, the calculation is input into the control system, which controls, for example, a roller press to perform roller pressing according to the set program, thereby outputting flat segments 11 and corrugated segments 12 on a metal strip 1.

[0086] In this application, the outer ring of the planar segment 11 on adjacent coils 100 is a corrugated segment 12, and the outer ring of the corrugated segment 12 is the planar segment 11. That is, the planar segment 11 and the corrugated segment 12 are alternately arranged from the inner ring to the outer ring, ensuring that the vent holes are evenly distributed on a single vent surface, thus ensuring uniform venting. Here, the vent holes are the corrugated segments on the corrugated segment 12, and each corrugation can serve as a vent hole, ensuring uniform venting, stable flame, and less smoke.

[0087] In a preferred embodiment of the invention, the planar segment 11 is coiled around the outer periphery of the annular body 2; or the corrugated segment 12 is coiled around the outer periphery of the annular body 2. For example... Figure 5 As shown, the planar segment 11 can be coiled one or more times to increase the thickness of the inner wall of the honeycomb structure and improve the overall compressive strength. Alternatively, the corrugated segment 12 can be coiled around the outer periphery of the annular body 2. The annular body 2 in this application can be a steel ring or other ring-shaped objects.

[0088] The specific operation is as follows: a small flat section 11 is connected to the ring body 2, or a corrugated strip is directly connected to the ring body 2, and then the ring body is wound to form a honeycomb. Alternatively, the ring body 2 can be used to replace the first flat section 11, and the corrugated section 12 is connected to the outer circumference of the steel ring. Then the flat section 11 connected to the corrugated section 12 is coiled around the outer circumference of the corrugated section 12 to finally form a honeycomb.

[0089] In this embodiment of the invention, the term "multiple" refers to two or more, unless otherwise explicitly defined. The terms "install," "connect," and "fix" should be interpreted broadly.
