[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1-Figure 4 The utility model proposes a cross-corrugation processing device for corrugated plates with equal cross-sections in transverse and longitudinal directions, comprising a pressing component 2, an extrusion component 3 and a support platform 1, wherein:

[0033] The support platform 1 is provided with a first fixing frame 11, and the pressing assembly 2 includes a first pressing die 21 and a first driving mechanism 22. The first pressing die 21 is slidably connected to the first fixing frame 11 through a slider rail, and the first driving mechanism 22 is fixed to the first fixing frame 11. The output end of the first driving mechanism 22 is connected to the first pressing die 21, and the first driving mechanism 22 drives the first pressing die 21 to move longitudinally.

[0034] The extrusion assembly 3 also includes an extrusion seat 31 arranged on both sides of the first fixed frame 11 on the support platform 1. The extrusion seat 31 is slidably connected to the support platform 1 through a slide rail slider. A second driving mechanism 32 is also provided on the side of the two extrusion seats 31 away from the first fixed frame 11. The second driving mechanism 32 is fixed on the support platform 1, and the output end of the second driving mechanism 32 is connected to the extrusion seat 31. The second driving mechanism 32 drives the extrusion seat 31 to move horizontally.

[0035] In this embodiment:

[0036] The support platform 1 is used to support the mechanism and components;

[0037] The first fixing frame 11 is used to fix the pressing assembly 2;

[0038] The first lower pressing die 21 and the first driving mechanism 22 are used to apply downward extrusion force to the corrugated plate;

[0039] The second driving mechanism 32 and the extrusion seat 31 are used to apply extrusion force to both sides of the corrugated plate;

[0040] In a specific embodiment, the support platform 1 includes a mounting plate 42 and a support frame, the mounting plate 42 is installed on the support frame, and then the first fixed frame 11 is installed on the support frame, a slide rail is respectively provided on the inner walls on both sides of the first fixed frame 11, and a slider is respectively provided on the outer walls on both sides of the first lower die 21, which cooperates with the first fixed frame 11 through the slider and realizes the movement on the first fixed frame 11 through the first driving mechanism 22. A slider is provided at the bottom of the extrusion seat 31, and a transverse slide rail is provided on the top of the mounting plate 42. The extrusion seat 31 moves transversely on the mounting plate 42 through the slider. When processing the corrugated plate, the first lower die 21 applies downward pressure on the corrugated plate, and at the same time, the extrusion seats 31 on both sides apply extrusion force to the corrugated plate. The downward extrusion and the extrusion toward the center on both sides are carried out simultaneously, and the corrugated plate with equal transverse and longitudinal sections is obtained by processing.

[0041] In one embodiment, the corrugated plate is the main maintenance structure of the LNG membrane storage tank. Generally speaking, the corrugated plate is provided with cross corrugations 6 (i.e., folds), and the cross corrugations 6 are used to release the cold and hot stress of liquid hydrogen. In the prior art, stamping is used to make corrugated plates. Stamping will exert a large pressure on the corrugated plates. After forming, the corrugated plates are thinned a lot, and the structural strength of the corrugated plates is prone to decrease. Secondly, when subjected to low-temperature stress, they cannot be stretched and flattened under stress. Some prior arts use cross corrugated plates with unequal cross-sections in the horizontal and vertical directions to enable the corrugated plates to withstand higher stresses, but the cross corrugated plates with unequal cross-sections in the horizontal and vertical directions occupy more space; and the present application uses downward extrusion and extrusion on both sides to form corrugated plates with equal cross-sections in the horizontal and vertical directions. The cross-sections of the two cross corrugations 6 in the corrugated plates with equal cross-sections in the horizontal and vertical directions are equal, and the force is more uniform. Secondly, the thinning amount is less, and the corrugated plate after forming is thicker and can bear greater low-temperature stress.

[0042] Furthermore, it also includes a conveying assembly 4 , which includes rollers 41 arranged on both sides of the first fixed frame 11 , and a plurality of rollers 41 are horizontally installed on both sides of the first fixed frame 11 through a mounting plate 42 .

[0043] In this embodiment:

[0044] The conveying assembly 4 is used for conveying the corrugated sheet;

[0045] In a specific embodiment, the rollers 41 are horizontally arranged at the front side of the first fixed frame 11 and the rear side of the first fixed frame 11 and fixed on the support platform 1. The number of rows of rollers 41 can be selected according to actual conditions. There can be two rows of rollers 41, with the corrugated plates clamped between the two rows of rollers 41. There can also be one or two rollers 41 above a row of rollers 41 to cooperate in clamping the corrugated plates. As long as the upper rollers 41 and the lower rollers 41 can clamp the corrugated plates and transport them horizontally, the conveying of the corrugated plates by the rollers 41 can be automated to reduce manpower consumption.

[0046] Furthermore, the pressing assembly 2 also includes a second pressing die 23 and a third driving mechanism 24. The two second pressing dies 23 are arranged on both sides of the bottom of the first pressing die 21. The third driving mechanism 24 passes through the first pressing die 21 and is fixedly connected to the first pressing die 21. The output end of the third driving mechanism 24 is fixedly connected to the second pressing die 23.

[0047] In this embodiment:

[0048] The second lower die 23 can support the bottom of the corrugated portion of the corrugated sheet;

[0049] The third driving mechanism 24 is used to adjust the position of the second lower die 23;

[0050] In a specific embodiment, the second driving mechanism 32 adjusts the position of the second lower die 23, and can further adjust the curved surfaces at the two intersecting corrugations 6. When the second driving mechanism 32 is adjusted, the distance between the bottom surface of the second lower die 23 and the bottom surface of the first lower die 21 can be adjusted, thereby adjusting the height of the curved surface (and the nodes) of the intersecting corrugations 6 to adapt to different needs.

[0051] Furthermore, a plurality of vertically intersecting transverse shaping portions 211 are provided at the bottom of the first lower die 21 .

[0052] A guide groove 2111 is formed at the intersection of the molding portion 211 , and the second lower pressing die 23 is disposed in the guide groove 2111 and connected to the second driving mechanism 32 .

[0053] In this embodiment:

[0054] The molding part 211 is used for stamping plasticity;

[0055] In a specific embodiment, the guide groove 2111 is used to display the second lower pressing die 23, the bottom of the molding portion 211 is a V-shaped slope, the molding portion 211 includes three intersecting V-shaped portions, and the guide groove 2111 is arranged at the intersection of the molding portion 211, and the second lower pressing portion is arranged inside the two guide grooves 2111, and the height can be adjusted in the guide groove 2111, thereby changing the height of the curved surface at the cross corrugation 6 of the processed corrugated plate.

[0056] In one embodiment, the specific shape of the shaping portion 211 can be set according to actual needs. The shaping portion 211 can also be similar to a tic-tac-toe shape, in which the transversely staggered parts can be set according to actual conditions.

[0057] Furthermore, the pressing assembly 2 also includes a fourth driving mechanism 25 and a lower die base 26 . The lower die base 26 is arranged at the bottom of the second lower pressing die 23 . The fourth driving mechanism 25 is fixed on the support platform 1 . The output end of the fourth driving mechanism 25 is fixedly connected to the bottom of the lower die base 26 .

[0058] In this embodiment:

[0059] The lower die base 26 is used to support the bottom of the corrugated plate;

[0060] In a specific embodiment, the lower die base 26 and the two extrusion seats 31 form a complete lower die. The fourth driving mechanism 25 is arranged on the support platform 1. The fourth driving mechanism 25 can drive the lower die base 26 to move up and down, and cooperate with the third driving mechanism 24 and the second lower pressing die 23 to change the height of the intersection of the processed corrugated plate.

[0061] Furthermore, it also includes a clamping component 5, which includes a clamping plate 51. A second fixing frame 53 is provided on the top of the extrusion seat 31, and a fifth driving mechanism 52 is fixed on the second fixing frame 53. The output end of the fifth driving mechanism 52 faces the bottom side and is connected to the clamping plate 51.

[0062] In this embodiment:

[0063] The clamping plate 51 is used to clamp the two sides of the corrugated plate.

[0064] In a specific embodiment, two second fixing frames 53 are fixed on two extrusion seats 31 through a slide rail connecting plate, and the fifth driving mechanism 52 on the second fixing frames 53 pushes the clamping plate 51 downward and clamps both sides of the corrugated plate to facilitate the extrusion process of the corrugated plate.

[0065] Furthermore, a groove cooperating with the molding portion 211 is provided on the extrusion seat 31 , and the groove is located on the side of the extrusion seat 31 facing the bottom of the clamping plate 51 , and the fitting parts of the two extrusion seats 31 cooperate with the intersection part of the molding portion 211 .

[0066] In this embodiment:

[0067] The grooves are used to position the corrugated sheets;

[0068] In a specific embodiment, the groove is used to position the corrugated plate so that the first lower die 21 can be pressed down to a precise position. The two extrusion seats 31 are fitted together to form a groove that cooperates with the molding portion 211. Extrusion from the left and right sides by the two extrusion seats 31 can reduce the amount of thinning and withstand higher low-temperature stress. Compared with processing by stamping, stamping will directly result in no rebound of the curved surface at the intersection, which is easy to increase the amount of thinning (that is, it will be much thinner after stamping than before).

[0069] Furthermore, the method for processing cross-corrugations of corrugated plates with equal cross-sections in transverse and longitudinal directions comprises the following steps:

[0070] S1. The workpiece is transported to the bottom of the pressing assembly 2 by the conveying assembly 4 composed of the roller 41, and the clamping plate 51 is pressed down by the fifth driving mechanism 52 to clamp both sides of the workpiece;

[0071] S2. Adjust the output ends of the first drive mechanism 22, the second drive mechanism 32, the third drive mechanism 24 and the fourth drive mechanism 25 to a preset position;

[0072] S3. Control the first drive mechanism 22 to drive the first lower die 21 to press the workpiece while controlling the second drive mechanisms 32 on both sides to drive the two extrusion seats 31 to extrude the workpiece toward the center;

[0073] S4. The first driving mechanism 22 and the second driving mechanism 32 respectively drive the first lower die 21 and the extrusion seat 31 to loosen, the fifth driving mechanism 52 drives the clamping plate 51 to loosen the workpiece, and the roller 41 transports the workpiece to the next cross corrugation 6 position for processing.

[0074] In a specific embodiment, the corrugated plate is horizontally conveyed to the right by a conveying assembly 4 composed of rollers 41 to a clamping mechanism for fixation, and then the upper first lower die 21 and the left and right extrusion seats 31 are simultaneously extruded downward, left and right to complete the forming of the corrugated plate at one time. Compared with stamping forming, the utility model can reduce the thinning amount of the corrugated plate after forming. When encountering low-temperature stress, the strength of the structure at the intersection is higher and has better stress bearing capacity. Finally, the utility model can complete the processing of corrugated plates with equal cross-sections in the horizontal and vertical directions, and can control the height of the wave nodes at the intersection of the corrugations according to actual needs.

[0075] In one embodiment, the types of the first drive mechanism 22, the second drive mechanism 32, the third drive mechanism 24, the fourth drive mechanism 25 and the fifth drive mechanism 52 can be selected according to actual conditions, and can be cylinders, electric cylinders or linear motors, any mechanism that can perform linear motion.

[0076] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
