[0040] like Figures 1 to 6 As shown, Figure 1 A schematic diagram of a honeycomb body provided by the present invention is shown. Figure 2 Shows Figure 1 Enlarged view of point A in the middle. Figure 3 A schematic diagram of the morphology of the honeycomb body provided by the present invention is shown. Figure 4 Another schematic diagram of the honeycomb body provided by the present invention is shown. Figure 5 A schematic diagram of a honeycomb body having an annular body provided by the present invention is shown. Figure 6 A schematic diagram of a method for manufacturing a honeycomb body provided by the present invention is shown.

[0041] A honeycomb body according to an embodiment of the present invention comprises: a metal strip 1, the metal strip 1 comprises a plurality of planar segments 11 and a plurality of corrugated segments 12, the planar segments 11 and the corrugated segments 12 are alternately connected, and the metal strip 1 is coiled to form a honeycomb body.

[0042] The present application uses a single-layer metal strip having a flat section 11 and a corrugated section 12, and forms a regular corrugated shape by rolling or stamping.

[0043] The first case is that the plane segment 11 and the corrugated segment 12 are connected alternately, and the plane segment 11 can be located at the initial end of the metal strip 1, so that the end of the plane segment 11 is connected to the initial end of the corrugated segment 12, and the initial end of the corrugated segment 12 is connected to the initial end of the next plane segment 11, and the end of the next plane segment 11 is connected to the initial end of the next corrugated segment 12, and so on. It can also be that the corrugated segment 12 can be located at the initial end of the metal strip 1 and then the plane segment 11 is set, as long as the plane segment 11 and the corrugated segment 12 are set alternately. It should be noted that the initial end of the metal strip 1 of the present application is the side where the metal strip 1 is opened for winding, and the end corresponds to the initial end.

[0044] The second situation is that the plane segment 11 and the corrugated segment 12 are not connected alternately. For example, the first segment at the initial end of the metal strip 1 may be the plane segment 11, the second segment is the corrugated segment 12, the third segment is still the corrugated segment 12, the fourth segment is the plane segment 11, and the fifth segment is still the plane segment 11. This situation is for a coil 100 provided with one plane segment 11 and one corrugated segment 12. Alternatively, the first segment at the initial end of the metal strip 1 may be the plane segment 11, the second segment is the corrugated segment 12, the third segment is still the plane segment 11, the fourth segment is the corrugated segment 12, the fifth segment is still the corrugated segment 12, the sixth segment is the plane segment 11, the seventh segment is the corrugated segment 12, the eighth segment is the plane segment 11, the ninth segment is the plane segment 11, and so on. This situation can be referred to Figure 2 Each coil 100 has two plane segments 11 and two corrugated segments 12. Of course, when there are multiple plane segments 11 and multiple corrugated segments 12 on the coil 100, the plane segments 11 and the corrugated segments 12 are not connected alternately at the connection of two adjacent coils 100, but are two identical shapes, either all of which are corrugated segments 12 or all of which are plane segments 11.

[0045] pass Figure 1-5 It can be seen from the honeycomb body shown that the honeycomb body also has a plurality of air outlet rings. In the present application, the corrugated section 12 and the flat section 11 cooperate with each other so that the waves on the corrugated section 12 serve as air outlet channels. The plurality of corrugated sections 12 are evenly distributed along the honeycomb body, which ensures uniform air outlet and can also stabilize and evenly distribute the airflow and reduce the generation of smoke.

[0046] The metal strip 1 is coiled multiple times to form a honeycomb body. After the metal strip 1 is coiled, multiple coils 100 are formed. Therefore, the honeycomb body of the present application is composed of multiple mutually constrained coils 100. In addition, the flat section 11 and the corrugated section 12 are constrained to each other, and there will be no problem of local bulging upward or moving downward. The honeycomb body is not easy to warp or cause tempering, and has a simple structure and low cost.

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

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

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

[0050] Figure 1As shown, the present application can form a first coil 100a by coiling the plane segment 11 once, and form a second coil 100b by coiling the corrugated segment 12 once, and the outer circle of the first coil 100a is provided with the second coil 100b, and the outer circle of the second coil 100b is provided with the first coil 100a, and so on, and multiple first coils 100a and second coils 100b are alternately arranged to form a honeycomb body. That is, each coil 100 in the honeycomb body is a separate plane segment 11 or corrugated segment 12.

[0051] The innermost side of the honeycomb body may be the first winding circle 100a or the second winding circle 100b. Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after winding one circle, a first winding circle 100a is formed, and then the corrugated segment 12 is wound around the outer periphery of the first winding circle 100a to form a second winding circle 100b. Then, the next planar segment 11 is wound around the outer periphery of the second winding circle 100b, and so on to form a honeycomb body.

[0052] In addition, the plane section 11 can be wound for multiple turns as required, and the length of the plane section 11 and the number of turns after winding can be set before pressing. The lengths of different plane sections 11 and corrugated sections 1212 can be calculated based on the preset inner and outer diameters of the honeycomb body, the thickness of the metal strip 1, the wave height of the corrugated section 12 and other parameters.

[0053] The first winding coils 100a and the second winding coils 100b of the present application are arranged alternately, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first winding coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly 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, and the coils 100 include a planar section 11 and a corrugated section 12, wherein the outer side of the corrugated section 12 is the planar section 11 of an adjacent coil 100, and the outer side of the planar section 11 is the corrugated section 12 of an adjacent coil 100.

[0055] In a preferred embodiment of the present invention, each coil 100 includes at least one flat section 11 and at least one corrugated section 12 .

[0056] like Figure 3-4 As shown, the metal strip 1 is wound to form a plurality of windings 100, each of which may include a flat section 11 and a corrugated section 12. Figure 3 As shown, each coil 100 has a flat section 11 and a corrugated section 12, but it can also be Figure 4As shown, each winding 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 winding coil 100 may be 3, 4, 5, 6, 8, 9, 10, 12 or even more, and the present application does not impose any limitation thereto.

[0057] As long as the outer circle of the plane section 11 on the adjacent winding ring 100 is the corrugated section 12, and the outer circle of the corrugated section 12 is the plane section 11, that is, the plane section 11 and the corrugated section 12 are arranged alternately from the inner circle to the outer circle, it is ensured that the outlet holes are evenly distributed on a gas outlet surface, and the gas outlet is uniform. Here, the gas outlet hole is the wave segment on the corrugated section 12, and each wave can be used as a gas outlet hole, ensuring uniform gas outlet, stable flame, and less smoke.

[0058] In a preferred embodiment of the present invention, it further comprises an annular body 2 , wherein the metal strip 1 is coiled around the outer circumference 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, a circle or a section of the planar segment 11 is wrapped around the annular body 2, or 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 body.

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

[0061] In such Figure 1-5 As shown, the corrugation segment 12 includes a plurality of crests 121 and a plurality of troughs 122, wherein the crest near the starting end of the corrugation segment 12 is the first crest 1210, the trough near the starting end of the corrugation segment 12 is the first trough 1220, the crest near the end of the corrugation segment 12 is the Nth crest 1211, and the trough near the end of the corrugation segment 12 is the Nth trough 1221.

[0062] In such Figure 1-5 In the honeycomb body shown, part of the transition section 101 is connected between the first wave crest 1210 and the N-th wave crest 1211 on the same corrugated section 12, and the remaining part of the transition section 101 is connected between the first wave valley 1220 and the N-th wave valley 1221. An irregular quadrilateral is formed by connecting the adjacent first winding coil 100a and the second winding coil 100b through two transitions, the first wave crest 1210 and the N-th wave crest 1211, and the first wave valley 1220 and the N-th wave valley 1221. The quadrilateral can be used to coil the corrugated section 12 into a whole, and the corrugated section 12 and the plane section 11 can be tightly connected to form a whole, thereby avoiding the problem of warping of the honeycomb body.

[0063] exist Figure 3-4 In the honeycomb body shown, a transition section 101 is provided between two adjacent winding circles 100. Because the inner side of the planar section 11 after winding is in close contact with the outer periphery of the corrugated section 12 located on the inner circle, the first winding circle 100 located on the inner side has the corrugated section 12 at the initial end and the planar section 11 at the end, when the planar section 11 is wound toward the outer circle, it is necessary to wind from the trough 122 of the corrugated section 12 located at the initial end to its crest 121 and continue to wind against the outer periphery of the corrugated section 12 to form the second winding circle 100. Generally, the initial end of the second winding coil 100 is a flat section 11, and the end is a corrugated section 12. When the corrugated section 12 at the end of the winding coil 100 is wound to the third winding coil 100, the transition section 101 will be connected from the Nth wave peak 1211 of the second corrugated section 12 at the end of the second winding coil 100 to the first wave valley 1220 of the corrugated section 12 at the initial end of the third winding coil 100. At the same time, the inner side of the transition section 101 will abut against the first wave peak 1210 of the second corrugated section 12 at the initial end of the second winding coil 100, and this cycle will be repeated to form a tightly connected honeycomb body to avoid the problem of honeycomb body warping caused by local upward bulging or downward movement.

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

[0065] like Figure 1-5 As shown, whether the corrugated section 12 forms a coil 100 alone or the corrugated section 12 is a regular shape band, each wave is triangular in shape, and the size and shape of adjacent waves are consistent and centrally symmetrical, so that the honeycomb body is beautiful, the process is simple, and the air outlet holes are uniform. Generally speaking, the wave size of the corrugated section 12 on the same air outlet ring is consistent.

[0066] Of course, the wave sizes on the corrugated segment 12 may also be different, especially the corrugated segment 12 located on the inner circle and the corrugated segment 12 located on its outer circle. The wave sizes may be different. For example, the air outlet holes in the outer circle may be larger than the air outlet holes in the inner circle. In some cases, the air outlet holes in the inner circle may be larger than the air outlet holes in the outer circle to increase the central firepower.

[0067] A method for manufacturing a honeycomb body according to an embodiment of the present invention comprises:

[0068] Selecting a metal thin strip 1 and determining basic parameters of a prefabricated honeycomb body;

[0069] Calculate the lengths of the flat section 11 and the corrugated section 12 according to the basic parameters of the honeycomb body;

[0070] According to the obtained lengths of the flat section 11 and the corrugated section 12, a plurality of flat sections 11 and a plurality of corrugated sections 12 are pressed on the metal strip 1; and then the metal strip 1 is wound multiple times to form a honeycomb body.

[0071] Among them, the basic parameters of the honeycomb body can be the inner diameter of the honeycomb body a, the circumference of the coil 100 is S, the size of the outlet hole, since the outlet hole of the present application is equivalent to each wave of the corrugated section 12, the size of the outlet hole is the wave height d and the wavelength c of the corrugated section 12, in addition, assuming that the thickness of the metal strip 1 is b, the circumference of the i-th coil 100 is S i ,but:

[0072] S i =π[a+(i-1)(b+d)], wherein i represents the number from the inside to the outside, and the wave height is the height from the inside of the wave crest 121 to the lowest point of the wave trough 122, that is, the distance from the highest point on the inside of a wave crest 121 to the periphery of the plane segment 11 located on the inside of the wave.

[0073] The pressing of the present application can be by rolling, stamping and the like, as long as the flat segment 11 and the corrugated segment 12 can be formed on the metal strip 1 at the same time. The first case is that the flat segment 11 and the corrugated segment 12 are connected alternately, for example, the flat segment 11 is located at the initial end of the metal strip 1, and the end of the flat segment 11 is connected to the initial end of the corrugated segment 12, and the initial end of the corrugated segment is connected to the initial end of the next flat segment 11, and the end of the next flat segment 11 is connected to the initial end of the next corrugated segment 12, and so on. At the same time, the initial end of the metal strip 1 can also be a corrugated segment 12 and then a flat segment 11 is set, as long as the flat segment 11 and the corrugated segment 12 are set alternately. It should be noted that the initial end of the metal strip 1 of the present application is the side where the metal strip 1 is opened for winding, and the end corresponds to the initial end. The second situation is that the plane segment 11 and the corrugated segment 12 are not connected alternately. For example, the first segment at the initial end of the metal strip 1 may be the plane segment 11, the second segment is the corrugated segment 12, the third segment is still the corrugated segment 12, the fourth segment is the plane segment 11, and the fifth segment is still the plane segment 11. This situation is for a coil 100 provided with one plane segment 11 and one corrugated segment 12. Alternatively, the first segment at the initial end of the metal strip 1 may be the plane segment 11, the second segment is the corrugated segment 12, the third segment is still the plane segment 11, the fourth segment is the corrugated segment 12, the fifth segment is still the corrugated segment 12, the sixth segment is the plane segment 11, the seventh segment is the corrugated segment 12, the eighth segment is the plane segment 11, the ninth segment is the plane segment 11, and so on. This situation can be referred to Figure 2Each coil 100 has two plane segments 11 and two corrugated segments 12. Of course, when there are multiple plane segments 11 and multiple corrugated segments 12 on the coil 100, the plane segments 11 and the corrugated segments 12 are not connected alternately at the connection of two adjacent coils 100, but are two identical shapes, either all of which are corrugated segments 12 or all of which are plane segments 11.

[0074] The metal strip 1 is coiled multiple times by the equipment to form a honeycomb body. After coiling, the metal strip 1 becomes a plurality of coiled circles 100. Therefore, the honeycomb body of the present application is composed of a plurality of mutually constrained coiled circles 100, and the flat sections 11 and the corrugated sections 12 are alternately connected, so that the honeycomb body will not have the problem of partial bulging upward or moving downward, and is not easy to warp or cause tempering, and has a simple structure and low cost.

[0075] In the present application, the corrugated section 12 and the flat section 11 cooperate with each other so that the waves on the corrugated section 12 serve as an air outlet channel. Multiple corrugated sections 12 are evenly distributed along the honeycomb body, which not only ensures uniform air outlet, but also plays a role in stabilizing and evenly distributing the airflow and reducing the generation of smoke.

[0076] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, oval, triangle, rectangle, hexagon, octagon, dodecagon, etc., and the present application does not limit this.

[0077] In a preferred embodiment of the present invention, the planar section 11 is coiled once to form a first coiled coil 100a, and the corrugated section 12 is coiled once to form a second coiled coil 100b. The second coiled coil 100b is arranged outside the first coiled coil 100a, and the first coiled coil 100a is arranged outside the second coiled coil 100b. A honeycomb body is formed by alternately arranging a plurality of first coiled coils 100a and second coiled coils 100b.

[0078] In a preferred embodiment of the present invention, one of the first winding coil 100a or the second winding coil 100b is disposed at the innermost side of the honeycomb body.

[0079] Figure 1 As shown, the present application can form a first coil 100a by coiling the plane segment 11 once, and form a second coil 100b by coiling the corrugated segment 12 once, and the outer circle of the first coil 100a is provided with the second coil 100b, and the outer circle of the second coil 100b is provided with the first coil 100a, and so on, and multiple first coils 100a and second coils 100b are alternately arranged to form a honeycomb body. That is, each coil 100 in the honeycomb body is a separate plane segment 11 or corrugated segment 12.

[0080] The innermost side of the honeycomb body may be the first winding circle 100a or the second winding circle 100b. Figure 1The planar segment 11 is shown as the starting end of the metal strip 1, and after winding one circle, a first winding circle 100a is formed, and then the corrugated segment 12 is wound around the outer periphery of the first winding circle 100a to form a second winding circle 100b. Then, the next planar segment 11 is wound around the outer periphery of the second winding circle 100b, and so on to form a honeycomb body.

[0081] In addition, the plane section 11 can be wound for multiple turns as required, and the length of the plane section 11 and the number of turns after winding can be set before pressing. The lengths of different plane sections 11 and corrugated sections 12 can be calculated based on the preset inner and outer diameters of the honeycomb body, the thickness of the metal strip 1, the wave height of the corrugated section 12 and other parameters.

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

[0083] In a preferred embodiment of the present invention, the lengths of the planar section 11 and the corrugated section 12 are adjusted so that each winding coil 100 has both the planar section 11 and the corrugated section 12, and the outer side of the corrugated section 12 is the planar section 11 of the adjacent winding coil 100, and the outer side of the planar section 11 is the corrugated section 12 of the adjacent winding coil 100.

[0084] like Figure 3-5 As shown, each coil 100 may be composed of a flat section 11 and a corrugated section 12, or may be composed of a flat section 11 and a corrugated section 12. Figure 4 As shown, each coil 100 has two plane segments 11 and two corrugated segments 12. Of course, the number of plane segments 11 and corrugated segments 12 on each coil 100 may also be 3, 4, 5, 6, 8, 9, 10, 12 or even more. This application does not limit this.

[0085] When pressing the metal strip 1, it is only necessary to calculate the length of each flat segment 11 and corrugated segment 12 according to the relationship between the inner and outer diameters of the honeycomb body, the number of flat segments 11 and corrugated segments 12 on each winding circle 100, the thickness of the metal strip 1, the wave height and wavelength of the corrugated segment 12. The system calculates the length of each flat segment 11 and corrugated segment 12 according to the relationship between the different inner and outer diameters, and then inputs it into the control system. The control system controls, for example, a roller press to perform rolling according to a set program, and then outputs the flat segment 11 and corrugated segment 12 on a metal strip 1.

[0086] In the present application, the outer circle of the plane section 11 on the adjacent coiled ring 100 is the corrugated section 12, and the outer circle of the corrugated section 12 is the plane section 11, that is, the plane section 11 and the corrugated section 12 are arranged alternately from the inner circle to the outer circle, ensuring that the outlet holes are evenly distributed on a gas outlet surface, ensuring uniform gas outlet. Here, the outlet hole is the wave segment on the corrugated section 12, and each wave can be used as an outlet hole, ensuring uniform gas outlet, stable flame, and less smoke.

[0087] In a preferred embodiment of the present invention, the flat section 11 is wound around the outer circumference of the annular body 2; or the corrugated section 12 is wound around the outer circumference of the annular body 2.
