Description

Technical Field

[0001] The invention relates to the technical field of ring network cabinet panel forming technology, in particular to a ring network cabinet structure and a cabinet panel forming device thereof. Background Art

[0002] Ring main cabinets (RMCs) are critical equipment in distribution networks for power supply and fault isolation. Their enclosures are typically assembled from separate metal panels, including a back panel, roof panel, floor panel, side panels, and door panels. Traditionally, each panel is formed separately through press molding: First, a single sheet is cut and bent using a mold to create components like the back panel or side panels. The side panels are then punched to create an array of heat dissipation holes to ensure proper heat dissipation. Finally, the panels are secured together using welding or bolting.

[0003] In the prior art, for example, the patent application number "CN221080653U" proposes an assembled ring network cabinet, in which the cabinet body has cabinet side panels and a cabinet top panel, and the inner walls of the cabinet side panels are provided with upper and lower opposite hook-back parts with a curved arc hook-back structure, and a raised horizontal strip-shaped baffle is provided through the bottom surface of the cabinet top panel, forming a three-sided connection structure between the top panel and the side panel to meet the requirements of the ring network cabinet being detachable and easy to install. The cabinet side panels are also provided with a dust-proof ventilation net.

[0004] In the prior art, for example, a cabinet panel stamping forming device is proposed in patent application number "CN221935114U", in which the stamping plate drives the movable plate and the baffle to squeeze each other when moving downward, and drives the movable plate out of the mutual squeezing with the baffle under the action of the spring, so that the stamping plate continues to move downward to bend the cabinet panel.

[0005] However, in actual application, the above patented technology exposes some obvious defects. For example, in an assembled ring network cabinet, the side panels and back panels of the ring network cabinet adopt an independent molding design. Although a dustproof ventilation net is provided on the side panel, after the overall assembly, a continuous and unpartitioned open space is formed inside the cabinet, so that the working heat of each functional unit is disorderly convected inside the cabinet, which increases the working temperature inside the cabinet. At the same time, the alternating magnetic field generated by the busbar current between the functional units forms a cross-coupling with the secondary equipment, affecting the signal sampling accuracy of the ring network cabinet. And a cabinet panel stamping forming device, in which the stamping plate moves downward to extrude and bend its cabinet panel, when dealing with a ring network cabinet with an independent molding design for the side panels and back panel, not only the cabinet panels of each component need to be stamped separately, but also the dustproof ventilation net needs to be stamped separately on the side panel, and then these cabinet panels need to be assembled together through a connecting mechanism. This series of operations is time-consuming and labor-intensive, thereby reducing the forming efficiency of the cabinet panels of the ring network cabinet. Summary of the Invention

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] A ring main unit structure and a cabinet panel forming device thereof, wherein the ring main unit structure belongs to the field of power equipment cabinets and manufacturing, and the cabinet panel forming device belongs to the field of sheet metal processing automation and high-junction mechatronic forming technology. It is a device used for integrated stamping and forming of the back panel and side panels of the ring main unit, and has the effects of integrated stamping and forming and synchronous punching and bending.

[0041] A ring main unit structure, such as Figure 1-Figure 3 As shown, it includes a back-side integrated cabinet panel 1, the upper and lower ends of which are fixedly connected with end panels 2, and one end of the back-side integrated cabinet panel 1 is symmetrically hinged with multiple pairs of door panels 3, which are installed between the two end panels 2, and the interior of the back-side integrated cabinet panel 1 is fixedly connected with a partition frame 4, one end of the partition frame 4 is fixedly connected with a pair of heat dissipation fans 5, and one end of the back-side integrated cabinet panel 1 is symmetrically provided with a pair of heat dissipation holes 6, and the outer side of the heat dissipation hole 6 is fixedly connected with a triangular rain cover 7.

[0042] When in use, firstly, a back-side integrated cabinet panel 1 is set to replace the traditional back panel and side panel assembly structure to improve the structural strength and stability of the ring network cabinet. At the same time, a partition frame 4 is set to partition the interior of the ring network cabinet, thereby strengthening the isolation and protection of the internal components of the ring network cabinet, avoiding electromagnetic interference and heat transfer between different functional areas, and improving the operation safety and reliability of the ring network cabinet.

[0043] And by setting the heat dissipation holes 6 and using them in conjunction with the triangular rain cover 7, the air circulation inside and outside the ring network cabinet is effectively improved, and the situation of external rainwater entering the ring network cabinet is reduced. At the same time, starting the heat dissipation fan 5 can draw the air inside and outside the back integrated cabinet panel 1 to circulate through the heat dissipation holes 6, thereby taking away the heat generated by the internal components of the ring network cabinet and improving the heat dissipation efficiency of the ring network cabinet.

[0044] A cabinet plate forming device for a ring network cabinet structure, such as Figure 1 and Figures 4-10 As shown, the forming device includes an arch frame 8, the inner bottom of the arch frame 8 is fixedly connected to a stamping table 9, the top of the stamping table 9 is provided with a material trough 10, and the bottom of the material trough 10 is provided with a stamping model groove 11, one end of the arch frame 8 is evenly slidably connected to four lifting slides 12, the bottom of the four lifting slides 12 is fixedly connected to an upper mold 13, the four inner corners of the upper mold 13 are slidably connected to a pair of punching slides 14, one end of two adjacent punching slides 14 is fixedly connected to a punching mold 15, the bottom of the material trough 10 is symmetrically provided with a discharge groove 29, the stamping model groove 11 is installed between the two discharge grooves 29, and the inner sides of the stamping model groove 11 and the upper mold 13 are symmetrically provided with a punching groove 30;

[0045] One end of the upper die 13 is equipped with a punching assembly for driving the punching die 15 to move along the length direction of the punching slide 14, and one end of the arch 8 is equipped with a punching assembly for pushing the upper die 13 to embed into the punching model groove 11.

[0046] When in use, first place the unpunched back-side integrated cabinet panel 1 inside the material trough 10, and use the material trough 10 to position the four sides of the back-side integrated cabinet panel 1, then start the stamping assembly to drive the upper mold 13 to drive the punching mold 15 to move downward along the length direction of the lifting slide bar 12, and make the upper mold 13 push the back-side integrated cabinet panel 1 to embed into the inside of the stamping mold groove 11, and make the stamping mold groove 11 cooperate with the upper mold 13 to squeeze the back-side integrated cabinet panel 1 for stamping and forming;

[0047] After the upper mold 13 pushes the back-side integrated cabinet panel 1 to be embedded in the stamping model groove 11 for stamping and forming, the upper mold 13 drives the punching mold 15 to form a conflict with one end of the back-side integrated cabinet panel 1. At this time, the stamping assembly is continued to start to cooperate with the punching assembly to push the punching mold 15 along the length direction of the punching slide rod 14 through the punching groove 30, and at the same time, one end of the punching mold 15 squeezes the back-side integrated cabinet panel 1 to form a perforation. At the same time, the punching mold 15 squeezes the back-side integrated cabinet panel 1 to form a perforation. The debris generated by the perforation falls into the discharge trough 29 for collection, so that it is convenient to punch the two sections of the back-side integrated cabinet panel 1 when stamping the back-side integrated cabinet panel 1, so that the back-side integrated integrated cabinet panel 1 can replace the traditional back panel and side panel assembly structure, effectively improving the cabinet panel forming efficiency of the ring network cabinet.

[0048] like Figures 4-10 As shown, the punching assembly includes a resistance roller 16 rotatably connected to one end of the punching die 15, and a lifting chute 17 is provided at each of the four internal corners of the upper die 13. A lifting slide 18 is fixedly connected to the interior of the lifting chute 17. One end of the lifting slide 18 is slidably connected to a punching slider 19. One end of the punching slider 19 passes through the lifting chute 17 and is fixedly connected to a triangular resistance block 20. One end of the triangular resistance block 20 passes through the upper die 13 and forms a rolling resistance with the resistance roller 16. A reset spring 21 is provided on the outer periphery of the punching slide 14, and the reset spring 21 is installed between the punching slide 14 and the upper die 13.

[0049] Among them, the stamping assembly includes a pair of stamping racks 22 fixedly connected to the top of the upper mold 13, a pair of lifting slides 23 are opened on the top of the upper mold 13, and the internal sliding connection of the lifting slides 23 is connected to the stamping rack 24, and the bottom of the two stamping racks 24 is fixedly connected to the pressing plate 25, which is installed above the punching slider 19. The top of the arch frame 8 is fixedly connected to the electric push rod 26, and the output end of the electric push rod 26 is rotatably connected to the stamping gear 27. One end of the stamping gear 27 is symmetrically rotated and provided with a guide slide 28, and the guide slide 28 is slidably connected to the arch frame 8.

[0050] When in use, first place the unformed back-side integrated cabinet panel 1 inside the material trough 10, then start the electric push rod 26 to push the stamping gear 27 to move downward along the length direction of the guide slide 28, and at the same time make the stamping gear 27 synchronously conflict with the stamping rack 1 22 and the stamping rack 24, and push the stamping rack 1 22 and the stamping rack 24 to simultaneously drive the upper mold 13 and the pressing plate 25 to move downward along the length direction of the lifting slide 12, so that the upper mold 13 pushes the back-side integrated cabinet panel 1 to be embedded in the stamping model groove 11, and makes one end of the back-side integrated cabinet panel 1 be extruded and formed by the cooperation of the upper mold 13 and the stamping model groove 11;

[0051] At the same time, after the upper mold 13 pushes the back-side integrated cabinet panel 1 to be completely embedded in the stamping model groove 11, the electric push rod 26 is continued to be started to push the stamping gear 27 to move downward along the length direction of the guide slide 28. At this time, the stamping gear 27 is synchronously meshed with the stamping rack 1 22 and the stamping rack 2 24, and pushes the stamping gear 27 to drive the pressing plate 25 to move downward along the length direction of the guide slide 28, so that the pressing plate 25 pushes the punching slider 19 to drive the triangular resistance block 20 to move downward along the length direction of the lifting slide 2 18, and at the same time, the punching slider 19 pushes the triangular resistance block 20 to form a rolling resistance with the resistance roller 16, and pushes the resistance roller 16 to drive the punching mold 15 to pass through the punching slot 30 along the length direction of the punching slide 14. At the same time, one end of the punching die 15 squeezes the back-side integrated cabinet panel 1 to form a punching shape, and the punching slide bar 14 squeezes the reset spring 21 to produce a contraction deformation. Then, after the back-side integrated cabinet panel 1 is embedded in the stamping model groove 11 to complete the punching shape, the electric push rod 26 is started in reverse to drive the upper die 13 to disengage from the extrusion of the back-side integrated cabinet panel 1. At the same time, the upper die 13 drives the triangular interference block 20 to disengage from the interference with the interference roller 16. At this time, the reset spring 21 is relieved of the force and rebounds to push out the punching slide bar 14, so that the punching slide bar 14 drives the punching die 15 to disengage from the inside of the punching groove 30, thereby facilitating the stamping and punching of the back-side integrated cabinet panel 1, effectively improving the forming efficiency of the ring network cabinet panel.

[0052] like Figure 4-Figure 6 and Figures 9-12 As shown, a liquid collecting trough 31 is provided at the bottom of the discharge trough 29, a stripper plate 32 is installed inside the stamping mold groove 11, and stripper slide rods 33 are fixedly connected to the four corners of the bottom of the stripper plate 32. One end of the stripper slide rod 33 is slidably connected to the stamping table 9 and extends to the inside of the liquid collecting trough 31. A lifting spring 34 is fixedly connected to the inner bottom of the stamping mold groove 11, and the lifting spring 34 is fixedly connected to the bottom of the stripper plate 32.

[0053] Among them, the stripping plate 32 and the stripping slide rod 33 are internally provided with a communicating liquid guide groove 35, the output end of the liquid guide groove 35 is fixedly connected to a nozzle 36, the interior of the liquid collecting tank 31 is symmetrically fixedly connected to a pressure sleeve 37, the input end of the pressure sleeve 37 is fixedly connected to a liquid inlet valve 38, the input end of the liquid guide groove 35 is fixedly connected to a one-way valve 39, and a cooling component for cooling the coolant is installed inside the discharge trough 29;

[0054] Moreover, the cooling assembly includes a hollow heat exchange plate 40 fixedly connected to the inner side of the discharge trough 29, a plate-type refrigerator 41 is fixedly connected to the cooling end of the hollow heat exchange plate 40, and a plurality of guide plates 42 are evenly fixedly connected to one side of the hollow heat exchange plate 40, and the guide plates 42 are installed inside the discharge trough 29;

[0055] Furthermore, two adjacent guide plates 42 are arranged in a staggered manner to form an S-shaped curved flow channel.

[0056] When in use, when the stamping assembly is started to drive the upper mold 13 to push the back-side integrated cabinet panel 1 to be embedded in the stamping model groove 11, the bottom of the back-side integrated cabinet panel 1 is in conflict with the stripping plate 32, and the stripping plate 32 is pushed to squeeze the lifting spring 34 along the length direction of the stripping slide 33, so that the lifting spring 34 produces a contraction deformation, and when the stripping plate 32 pushes the stripping slide 33 to slide downward along the length direction of the pressure sleeve 37, the liquid inlet valve 38 is closed, so that the coolant accumulated in the liquid collecting tank 31 flows into the pressure sleeve 37 and will not flow out. At the same time, the one-way valve 39 only allows the coolant inside the pressure sleeve 37 to flow into the liquid guide groove 35, and does not allow the coolant inside the liquid guide groove 35 to flow back into the pressure sleeve 37, so that as the stripping slide 33 moves downward, the internal space of the pressure sleeve 37 is compressed, thereby utilizing the pressure change inside the pressure sleeve 37 to push the coolant through the liquid guide groove 35 into the interior of the nozzle 36, and then spray it into the interior of the punching slot 30 through the nozzle 36, thereby achieving heat exchange and cooling of the interior of the punching slot 30, and allowing the coolant after completing the heat exchange with the punching slot 30 to pass through the punching slot 30 and flow into the interior of the discharge trough 29 for collection;

[0057] Then, the coolant flowing into the discharge trough 29 flows into the interior of the liquid collecting tank 31 along the S-shaped curved flow channel formed between the multiple guide plates 42 for collection. When the coolant passes through the S-shaped curved flow channel, the contact stroke between the coolant and the hollow heat exchange plate 40 is effectively extended. At the same time, the plate refrigerator 41 is started to drive the heat exchange medium to continuously pass through the interior of the hollow heat exchange plate 40, and heat exchange and cooling are performed with the coolant passing through the S-shaped curved flow channel through the hollow heat exchange plate 40. The plate refrigerator 41 adopts the Danfoss R32 refrigerant micro-plate heat exchanger, which facilitates heat exchange and cooling of the coolant, thereby effectively improving the utilization rate of the coolant.

[0058] Then, when the stamping assembly is started in the reverse direction to drive the upper mold 13 to break away from the conflict with the back-side integrated cabinet panel 1, the rebound characteristic of the lifting spring 34 is utilized to make the lifting spring 34 rebound and eject the stripper plate 32, and make the stripper plate 32 push the back-side integrated cabinet panel 1 to move upward along the length direction of the stripper slide 33, and at the same time push the back-side integrated cabinet panel 1 out of the interior of the stamping mold groove 11, so as to achieve rapid demoulding of the back-side integrated cabinet panel 1;

[0059] When the stripping plate 32 drives the stripping slide rod 33 to move upward along the length direction of the pressure sleeve 37, the liquid inlet valve 38 is opened, so that the cooling liquid that flows into the collecting tank 31 and is cooled is affected by the pressure change inside the pressure sleeve 37, so that the cooling liquid is drawn into the interior of the pressure sleeve 37 for collection, thereby facilitating the circulation of the cooling liquid between the punching groove 30 and the pressure sleeve 37, and utilizing the cooling liquid to realize heat exchange and cooling inside the punching groove 30, thereby effectively improving the forming accuracy of the ring network cabinet panel.

[0060] like Figures 1-6 and Figure 11-13 As shown, a filter screen 43 is fixedly connected to the inside of the discharge chute 29 at an angle, and a dirt collecting cylinder 44 adapted to the filter screen 43 is fixedly connected to one side of the stamping table 9. A drain port 45 is opened at one end of the dirt collecting cylinder 44, and a drain valve 46 is fixedly connected to the inside of the drain port 45. A drain assembly for discharging stamping debris is installed inside the dirt collecting cylinder 44;

[0061] Among them, the sewage discharge component includes a sewage discharge auger 47 rotatably connected to the inside of the sewage collecting cylinder 44, one end of the sewage discharge auger 47 passes through the sewage collecting cylinder 44 and is fixedly connected to a bevel gear 1 48, one side of the stamping table 9 is rotatably connected to a bevel gear 2 49, and the bevel gear 2 49 is synchronously meshed with the two bevel gears 1 48, and one side of the stamping table 9 is fixedly connected to a sewage discharge motor 50, and the output end of the sewage discharge motor 50 is fixedly connected to the bevel gear 2 49.

[0062] During use, when the punching assembly is started and cooperated with the punching assembly to push the punching die 15 through the punching slot 30 to complete the punching of the back-side integrated cabinet panel 1, the debris generated by the punching die 15 passes through the punching slot 30 and falls into the inside of the discharge trough 29 for collection. At the same time, a filter 43 is provided to intercept and filter the debris and coolant falling into the inside of the discharge trough 29, so that the coolant passes through the filter 43 and flows into the inside of the liquid collection tank 31 for collection, while the debris slides along the guiding direction of the filter 43 to the inside of the sewage collection cylinder 44;

[0063] Then, when a lot of debris is collected inside the sewage collecting barrel 44, the sewage valve 46 is opened, and the sewage motor 50 is started to drive the bevel gear 2 49 to engage with the bevel gear 1 48, and the bevel gear 1 48 drives the sewage auger 47 to rotate, and at the same time, the sewage auger 47 pushes the debris along the length direction of the sewage collecting barrel 44 to move toward the sewage outlet 45, and discharges the debris from the sewage collecting barrel 44 through the sewage outlet 45, thereby facilitating the filtering and collection of debris generated by the punching and forming of the ring network cabinet panel, and effectively improving the practicality of the device.

[0064] The working principle of a ring main unit structure and its cabinet panel forming device provided by the present invention is as follows:

[0065] First, the electric push rod 26 is started to push the stamping gear 27 to move downward along the length direction of the guide slide 28, and at the same time, the stamping gear 27 is synchronously abutted against the stamping rack 1 22 and the stamping rack 2 24, and the stamping rack 1 22 and the stamping rack 2 24 are pushed to simultaneously drive the upper mold 13 and the pressing plate 25 to move downward along the length direction of the lifting slide 1 12, so that the upper mold 13 pushes the back-side integrated cabinet panel 1 to be embedded in the interior of the stamping mold groove 11;

[0066] At the same time, the bottom of the back integrated cabinet panel 1 is in conflict with the stripping plate 32, and the stripping plate 32 is pushed to squeeze the lifting spring 34 along the length direction of the stripping slide 33, so that the lifting spring 34 is contracted and deformed. When the stripping plate 32 pushes the stripping slide 33 to slide downward along the length direction of the pressure sleeve 37, the liquid inlet valve 38 is closed, so that the coolant accumulated in the liquid collecting tank 31 flows into the pressure sleeve 37 and will not flow out. At the same time, the one-way valve 39 only allows the coolant in the pressure sleeve 37 to flow into the liquid guide The coolant in the liquid-guiding groove 35 is not allowed to flow back into the pressure sleeve 37. As the stripping slide bar 33 moves downward, the internal space of the pressure sleeve 37 is compressed. The pressure change in the pressure sleeve 37 is used to push the coolant through the liquid-guiding groove 35 into the interior of the nozzle 36, and then sprayed into the interior of the punching groove 30 through the nozzle 36, thereby achieving heat exchange and cooling of the interior of the punching groove 30. The coolant, after completing the heat exchange with the punching groove 30, passes through the punching groove 30 and flows into the interior of the discharge trough 29 for collection.

[0067] After the upper mold 13 pushes the back-side integrated cabinet panel 1 to be completely embedded in the stamping model groove 11, the electric push rod 26 is continued to be started to push the stamping gear 27 to move downward along the length direction of the guide slide 28. At this time, the stamping gear 27 is synchronously meshed with the stamping rack 1 22 and the stamping rack 2 24, and the stamping gear 27 is pushed to drive the pressing plate 25 to move downward along the length direction of the guide slide 28, so that the pressing plate 25 pushes the punching slider 19 to drive the triangular resistance block 20 to move downward along the length direction of the lifting slide 2 18, and at the same time, the punching slider 19 pushes the triangular resistance block 20 to form a rolling resistance with the resistance roller 16, and pushes the resistance roller 16 to drive the punching mold 15 to pass through the punching slot 30 along the length direction of the punching slide 14, and at the same time, one end of the punching mold 15 squeezes the back-side integrated cabinet panel 1 to form a punching shape;

[0068] At the same time, the debris generated by the punching die 15 passes through the punching groove 30 and falls into the discharge trough 29 for collection. At the same time, a filter screen 43 is set to intercept and filter the debris and coolant falling into the discharge trough 29, so that the coolant passes through the filter screen 43 and flows into the collection tank 31 for collection, and the debris slides into the collection cylinder 44 along the guiding direction of the filter screen 43, and the coolant flowing into the discharge trough 29 flows into the collection tank 31 along the S-shaped curved flow channel formed between the multiple guide plates 42 to be collected. When the coolant passes through the S-shaped curved flow channel, the contact stroke of the coolant and the hollow heat exchange plate 40 is effectively extended. At the same time, the plate refrigerator 41 is started to drive the heat exchange medium to continuously pass through the hollow heat exchange plate 40, and the hollow heat exchange plate 40 is used to exchange heat and cool down with the coolant passing through the S-shaped curved flow channel.

[0069] Then, the electric push rod 26 is started in the reverse direction to drive the upper mold 13 to disengage from the extrusion of the back-side integrated cabinet panel 1, and at the same time, the upper mold 13 drives the triangular resistance block 20 to disengage from the resistance roller 16. At this time, the reset spring 21 is relieved of the force and rebounds to eject the punching slide bar 14, so that the punching slide bar 14 drives the punching mold 15 to disengage from the inside of the punching slot 30. At the same time, the rebound characteristics of the jacking spring 34 are utilized to make the jacking spring 34 rebound to eject the stripper plate 32, and make the stripper plate 32 push the back-side integrated cabinet panel 1 to move upward along the length direction of the stripper slide bar 33, and at the same time push the back-side integrated cabinet panel 1 to disengage from the inside of the stamping mold slot 11.

[0070] When the stripping plate 32 drives the stripping slide rod 33 to move upward along the length direction of the pressure sleeve 37, the liquid inlet valve 38 is opened, so that the cooling liquid that flows into the liquid collecting tank 31 and is cooled is affected by the pressure change inside the pressure sleeve 37, so that the cooling liquid is drawn into the interior of the pressure sleeve 37 for collection.
