[0002] The fusion of light atomic nuclei and the fission of heavy atomic nuclei can both release energy, which are called nuclear fusion energy and nuclear fission energy respectively. A large amount of heat is released during fusion or fission, and the energy is converted according to nuclear energy-mechanical energy-electrical energy. This kind of electricity is called nuclear power. The internal electronic components can be protected by the box. The standard box used for nuclear power has a total of 6 welds that need to be fully welded during the production process, and finally the production of nuclear power standard box is realized.

[0003] Nuclear power requires that the box body must be fully welded. Each box body has a total of 6 welds that need to be fully welded.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The technical solution of the utility model is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0026] Embodiment 1:

[0027] A nuclear power standard box provided in the present application includes an upper panel 1; a bottom edge 2 is provided on the back of the upper panel 1, a lower panel 3 is provided on the front of the bottom of the bottom edge 2, and side panels 4 are installed on both sides of the upper panel 1; the main improvement of the present patent is that the upper panel 1, the bottom edge 2 and the lower panel 3 are made into an integrated bending structure, and the side panels 4 are welded to both sides of the integrated bending structure, so that only welding on both sides is required, which greatly reduces the welding length of the nuclear power standard box, that is, reduces the deformation of the box.

[0028] Specifically, Figure 1As shown, by connecting the upper plate 1, the lower plate 3 and the bottom edge 2, and forming them in one piece on the bending center, two long sides are omitted during welding, and the stress in the direction of the bottom sheet during welding is greatly reduced, or even zero. Compared with the previous split welding method, the effect is obvious, and the bending efficiency is improved, that is, fewer parts and one-piece forming in the bending process, which reduces the welding workload, and the welding time is shortened from the original 8 minutes / unit to about 3.5 minutes / unit. This solution is only for standard boxes, except for non-standard boxes and nuclear power boxes that exceed the processing range of the bending center.

[0029] Furthermore, a U-shaped groove 5 is formed inside the upper plate 1, the bottom edge 2 and the lower plate 3, and a convex plate 401 is provided on one side of the side plate 4 close to the U-shaped groove 5;

[0030] Specifically, Figure 2 As shown, in order to achieve positioning when welding the side plate 4, the protruding plate 401 is located on one side of the side plate 4 and can be fixed by bolts. By locating the protruding plate 401 in the U-shaped groove 5 formed inside the upper plate 1, the bottom edge 2 and the lower plate 3, the side plate 4 can be positioned between the upper plate 1, the bottom edge 2 and the lower plate 3.

[0031] Furthermore, the top and bottom of the convex plate 401 are both provided with a groove 8, and a fixing mechanism 6 is movably installed inside the groove 8;

[0032] Specifically, Figure 3 As shown, in order to realize the movement of the fixing mechanism 6, two groups of grooves 8 are provided inside the top and bottom of the protruding plate 401. When the fixing mechanism 6 is extended or retracted, it moves inside the grooves 8.

[0033] Further, the fixing mechanism 6 includes a spring 601, an inclined block 602 and a convex block 603. The spring 601 is installed inside the groove 8, the inclined block 602 is installed on the top of the spring 601, and the convex blocks 603 are provided on both sides of the inclined block 602.

[0034] Specifically, Figure 3 As shown, in order to facilitate welding between the side plate 4 and the upper plate 1, the bottom edge 2 and the lower plate 3, two sets of springs 601 are arranged inside the groove 8, the inclined block 602 is arranged on the top of the spring 601, and the protrusion 603 is arranged on the outside of the bottom of the inclined block 602. The diameter of the protrusion 603 is the same as the inner diameter of the groove 8. When the worker pushes the side plate 4, the side plate 4 will drive the protrusion 401 to move, and then the inclined block 602 will be squeezed by the inner walls of the upper plate 1 and the lower plate 3. At this time, the spring 601 will be deformed. When the inclined block 602 is not subjected to the squeezing force, it will extend out under the action of the spring 601.

[0035] Furthermore, fixing grooves 7 are provided inside both sides of the upper and lower panels 1, 3, and the inclined blocks 602 are located inside the fixing grooves 7; through the fixing mechanisms 6 and fixing grooves 7 that cooperate with each other, the side panels 4 on both sides can be clamped and fixed on both sides of the integrated bending structure to avoid the inconvenience of shifting the side panels 4 when welding the side panels 4. At the same time, there is no need to manually assist in positioning the side panels 4 before welding.

[0036] Specifically, Figure 4 As shown, in order to fix the side plate 4, when the inclined block 602 is extended, the top of the inclined block 602 will be stuck in the inside of the fixing groove 7, so that the side plate 4 can be fixed on both sides of the upper and lower panels 1 and 3.

[0037] In order to reduce the docking gap between the side plate 4 and the integrated bending structure, a first slope 61 is arranged on the first top side wall of the inclined block 602 to facilitate the introduction of the inclined block 602 into the fixing groove 7, and a second slope 62 is arranged on the second top side wall of the inclined block 602, and a third slope 71 inclined inwardly and matching the second slope 62 is arranged on one side wall of the fixing groove 7. When the inclined block 602 is introduced into the fixing groove 7, the second slope 62 is gradually squeezed by the third slope 71, so that the inclined block 602 can be pressed against the other side wall of the fixing groove 7, thereby eliminating the gap between the inclined block 602 and the fixing groove 7. When welding the side plate 4, the weld width can be reduced, and the welding deformation of the nuclear power standard box can be further reduced.

[0038] In order to achieve the above-mentioned function of eliminating the gap by leaning against, the depth h1 of the third slope 71 needs to be greater than the height h2 of the first slope 61, and the height h2 of the first slope 61 needs to be greater than the height h3 of the third slope 71. Figure 5-7 shown.

[0039] Working principle: By connecting the upper recruitment plate 1, the lower recruitment plate 3 and the bottom edge 2 and forming them as one piece at the bending center, two long sides are omitted during welding, and the stress in the direction of the bottom film is greatly reduced during welding. Then the convex plate 401 is located in the U-shaped groove 5 formed inside the upper recruitment plate 1, the bottom edge 2 and the lower recruitment plate 3, and the side plate 4 can be positioned between the upper recruitment plate 1, the bottom edge 2 and the lower recruitment plate 3. At this time, the top of the inclined block 602 will be stuck in the fixing groove 7, and the side plate 4 can be fixed on both sides of the upper recruitment plate 1 and the lower recruitment plate 3. Then, it is only necessary to weld the side plates 4 on both sides of the upper recruitment plate 1 and the lower recruitment plate 3.

[0040] As described above, the utility model uses an upper calliper plate, a lower calliper plate, a bottom edge and a side plate in combination, connects the upper and lower calliper plates and the bottom edge, and forms them as one piece at the bending center, thereby eliminating two long sides during welding, and greatly reducing stress in the bottom sheet direction during welding, thereby improving bending efficiency and reducing welding workload.

[0041] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
