Description

Technical Field

[0001] This utility model belongs to the field of substation shell processing technology, and in particular relates to a bending device for processing substation shells. Background Technology

[0002] A substation is a place in a power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. The substation in a power plant is a step-up substation, whose function is to step up the electrical energy generated by the generator and feed it into the high-voltage power grid. The box-type substation is also called a prefabricated substation or prefabricated transformer substation. Box-type substations are suitable for mines, factories, oil and gas fields, and wind power stations. They replace the original civil engineering power distribution rooms and substations and become a new type of complete set of power distribution equipment.

[0003] During the processing of substation shells, bending is required. However, due to the different sizes of the shells, the molds used in existing bending equipment are mostly fixed with bolts, which makes it difficult to adjust the depth of the mold indentation according to the different bending angles of the shells, resulting in poor bending effect of the equipment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a bending device for processing substation shells, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a bending device for processing substation shells, comprising a workbench and a bending main component disposed on the rear side of the upper end face of the workbench, and further comprising:

[0007] The support frame is symmetrically fixed on the upper surface of the workbench. The support frame is rotatably connected to a connecting shaft, and a connecting plate is fixed on the inner side of the connecting shaft.

[0008] The lower mold component is fixed inside the connecting plate, and one end of the connecting shaft is connected to a drive mechanism to drive the lower mold component to rotate at multiple angles.

[0009] The locking mechanism is located inside the support frame on one side and is used to engage with the connecting plate to lock and limit the connecting plate.

[0010] The bending mechanism, located on the upper end face of the main bending component, is used to bend the substation shell plate on the upper end face of the lower die component.

[0011] Furthermore, the lower mold component has a quadrilateral cross-section, and bending grooves are evenly provided at the center of the four sides of the lower mold component, with the size of the bending grooves being different.

[0012] Furthermore, the drive mechanism includes a worm gear, a worm shaft, and a servo motor. The worm gear is fixed to one end of the connecting shaft, the worm shaft is meshed with the lower end of the worm gear, and the servo motor is fixed to one end of the worm shaft and is fixed to the side of the support frame.

[0013] Furthermore, the locking mechanism includes a locking groove, a positioning slide groove, a locking plate, and a return spring. The locking groove is evenly distributed on the outer side of the connecting plate, the positioning slide groove is distributed on one side inside the support frame, the locking plate is slidably engaged with the inner side of the positioning slide groove, the return spring is disposed on the inner side of the locking groove and sleeved on the outer surface of the locking plate, and the other end of the locking plate passes through the support frame and is slidably engaged with the inner side of the locking groove.

[0014] Furthermore, the bending mechanism includes a hydraulic rod, a bearing plate, and an upper die component. The hydraulic rod is symmetrically fixed on the left and right sides of the upper end face of the bending main component, the bearing plate is fixed on the output end of the hydraulic rod, and the upper die component is disposed on the lower end face of the bearing plate.

[0015] Furthermore, a locking groove is provided on the lower end face of the bearing plate. The cross-section of the locking groove is a "T" shaped structure. The upper end of the upper mold part is slidably engaged with the inner side of the locking groove, and the bolt passes through the bearing plate and is connected to the upper mold part.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses a support frame to limit the connecting shaft. Since the outer side of the lower mold component can have multiple sets of bending grooves of different depths, which cooperate with the drive mechanism, the connecting shaft can rotate at multiple angles. This allows for the selection of appropriate bending grooves based on the required bending size of the housing, ensuring normal operation of the equipment. Furthermore, the locking mechanism engages with the connecting plate, limiting its position and preventing offset or wobbling, thus ensuring the stability of the lower mold component. Finally, the bending mechanism bends the housing, ensuring the efficiency of the equipment. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-6 As shown, this utility model is a bending device for processing substation shells, including a workbench 1 and a bending main component 14 disposed on the rear side of the upper end face of the workbench 1, and further including:

[0029] The support frame 2 is symmetrically fixed on the upper surface of the workbench 1. The support frame 2 is rotatably connected to the connecting shaft 3, and the connecting shaft 3 is fixed to the inner side of the connecting plate 4. The lower mold part 5 has a quadrilateral cross-section. The lower mold part 5 has bending grooves 6 evenly opened at the center of the four sides. The size of the bending grooves 6 is different. The lower mold part 5 can be connected to the connecting shaft 3 and the connecting plate 4, so that the position of the lower mold part 5 can be limited, and the lower mold part 5 can be prevented from shifting or shaking. Furthermore, since multiple sets of bending grooves 6 of different depths can be opened on the outer side of the lower mold part 5, the appropriate bending groove 6 can be selected according to the different bending sizes required for the shell.

[0030] The lower mold component 5 is fixed inside the connecting plate 4. One end of the connecting shaft 3 is connected to a drive mechanism to drive the lower mold component 5 to rotate at multiple angles. The locking mechanism is set inside the support frame 2 on one side and is used to engage with the connecting plate 4 to lock and limit the connecting plate 4. The drive mechanism includes a worm gear component 7, a worm 8, and a servo motor 9. The worm gear component 7 is fixed to one end of the connecting shaft 3, the worm 8 is meshed with the lower end of the worm gear component 7, and the servo motor 9 is fixed to one end of the worm 8 and is fixed to the side of the support frame 2. The servo motor 9 can drive the worm 8 to rotate. Since the worm 8 can mesh with the worm gear component 7, when the worm 8 rotates, it can drive the worm gear component 7 to rotate accordingly. This allows for the adjustment of bending grooves 6 of different depths according to the required bending size. The locking mechanism includes a locking groove 10, a positioning slide 11, a locking plate 12, and a return spring 13. The locking groove 10 is evenly distributed on the connecting plate 4. On the outside, the positioning groove 11 is opened on one side inside the support frame 2. The locking plate 12 is slidably engaged with the inner side of the positioning groove 11. The return spring 13 is set on the inner side of the locking groove 10 and sleeved on the outer surface of the locking plate 12. The other end of the locking plate 12 passes through the support frame 2 and is slidably engaged with the inner side of the locking groove 10. The positioning groove 11 can limit the position of the locking plate 12, which can prevent the locking plate 12 from shifting or shaking. Then, before the connecting plate 4 reaches the designated position, the locking plate 12 can be pulled outward. When the bending groove 6 on the outside of the lower mold part 5 is perpendicular to the upper mold part 18, the locking plate 12 can be released. The return spring 13 can push the locking plate 12 to return to its original position, so that the locking plate 12 can be slidably engaged with the inner side of the locking groove 10, thereby limiting the position of the lower mold part 5. Since the substation shell is mostly made of thin metal sheets, when it is bent, the lower mold part 5 will not bend again.

[0031] A bending mechanism is installed on the upper end face of the bending main component 14 to bend the substation shell plate on the upper end face of the lower die component 5. The bending mechanism includes a hydraulic rod 15, a bearing plate 16, and an upper die component 18. The hydraulic rod 15 is symmetrically fixed on the left and right sides of the upper end face of the bending main component 14. The bearing plate 16 is fixed to the output end of the hydraulic rod 15. The upper die component 18 is installed on the lower end face of the bearing plate 16. The bearing plate 16 can be pushed downward by the hydraulic rod 15, so that the upper die component 18 can cooperate with the bending groove 6 on the upper end of the lower die component 5 to bend the shell. When bending is required, the operator can hold the thin shell sheet and place it on the bending groove. The upper mold plate 16 is placed on the upper end of the lower mold piece 5, and the hydraulic rod 15 is opened. The hydraulic rod 15 can push the support plate 16 and the upper mold piece 18 downward, so that the shell sheet can be bent. The lower end face of the support plate 16 is provided with a locking groove 17. The cross-section of the locking groove 17 is a "T" shaped structure. The upper end of the upper mold piece 18 is slidably engaged in the inner side of the locking groove 17, and the bolt passes through the support plate 16 and is connected to the upper mold piece 18. The locking groove 17 can limit the upper mold piece 18 and prevent the upper mold piece 18 from shifting. Since the upper mold piece 18 can be replaced and disassembled, it is convenient for subsequent maintenance and repair.

[0032] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
