Description

Technical Field

[0001] This utility model relates to the field of power fittings processing technology, specifically to a high-voltage line power fittings forming device. Background Technology

[0002] Power fittings are metal accessories that connect and combine various devices in a power system, serving to transmit mechanical loads, electrical loads, and provide certain protective functions. Especially in power systems, most power fittings need to withstand significant tensile forces during operation, and some must simultaneously ensure good electrical contact. They are crucial to the safety of conductors or towers; even the failure of a single fitting can cause a line fault. Therefore, the quality, correct use, and installation of fittings are of paramount importance for the safe transmission of power to the line. Currently, power fittings are generally manufactured using casting molding equipment.

[0003] A search revealed that Chinese Patent Publication No. CN221434917U discloses a high-voltage power fitting forming device, which includes a worktable with a cavity inside. A lifting plate is installed inside the worktable, and a pair of fixed frames are fixedly connected to the lower end of the lifting plate. A moving rod is slidably connected inside the fixed frames, and a rotating wheel is rotatably installed at the other end of the moving rod. The outer side of the rotating wheel is in contact with a fixed block. The middle part of the moving rod is rotatably connected to the upper end of the moving plate, and the lower end of the moving plate is threadedly connected to the surface of a bidirectional screw. The left end of the bidirectional screw is fixedly connected to the output end of a motor.

[0004] When in use, the device pushes the casting upward and separates it from the mold by ejecting the ejector rod. However, the small ejector plate ejects the formed power fitting. During ejection, the resistance between the casting and the inner wall of the mold is relatively large, which can easily cause the bottom of the formed power fitting to deform due to the ejector plate. In addition, the temperature of the casting is high when it is just formed and demolded, which can easily pose a risk to workers when handling the power fitting. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-voltage power fitting forming device, which can effectively solve the problem that the power fitting is difficult to remove due to excessive temperature after demolding in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a high-voltage power fitting forming device, including a workbench. A U-shaped fixing plate is provided on one side of the top of the workbench. A rotating shaft is rotatably connected to both ends of the U-shaped fixing plate. A lower mold is fixedly connected between the two rotating shafts. A first rotating wheel is rotatably connected to the outer side of the two rotating shafts away from the lower mold. A gear is fixedly connected to one end of each of the two rotating shafts. Two toothed blocks adapted to the two gears are fixedly connected to the top of the workbench. An installation groove is opened on the top of the workbench. A wire rope mesh is fixedly connected inside the installation groove. A fan corresponding to the position of the wire rope mesh is fixedly connected to the bottom of the workbench.

[0008] Furthermore, a hydraulic rod is fixedly connected to one side of the workbench, and the output end of the hydraulic rod is fixedly connected to a U-shaped fixed plate. Driven wheels are rotatably connected to both sides of the U-shaped fixed plate, and guide rails are fixedly connected to both sides of the top of the workbench. The first rotating wheel and the driven wheel are both tumblingly connected to the top of the guide rails.

[0009] Furthermore, the lower mold has a placement groove inside, a push plate is installed inside the placement groove, and an electric push rod is fixedly connected to the bottom of the lower mold. The output end of the electric push rod is fixedly connected to the push plate.

[0010] Furthermore, both sides of the lower mold are rotatably connected to support wheels, and both sides of the top of the worktable are fixedly connected to support blocks that are adapted to the positions of the support wheels.

[0011] Furthermore, a baffle is fixedly connected to one side of the workbench, and an inclined groove is provided inside the baffle. A vibrating plate is slidably connected inside the groove, and limit blocks are fixedly connected to both sides of the vibrating plate.

[0012] Furthermore, a vibration motor is fixedly connected to the top of one end of the vibration plate, a spring is fixedly connected to one side of the baffle, the other end of the spring is fixedly connected to the higher end of the vibration plate, and a button is fixedly connected to one side of the baffle. The button is electrically connected to the vibration motor and the electric push rod.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] 1. In this utility model, the hydraulic rod drives the U-shaped fixing plate to move horizontally to the right of the device above the wire rope net. When the gear teeth contact the tooth block, the tooth block drives the gear to rotate, thereby causing the lower mold to rotate 180 degrees. The high-temperature casting is poured onto the top of the wire rope net for heat dissipation, eliminating the need for manual demolding during operation. This reduces the labor intensity of workers, improves demolding efficiency, and prevents the high-temperature casting from posing a risk to workers.

[0015] 2. In this utility model, when the right side of the lower mold comes into contact with the baffle after being flipped over, the electric push rod works to separate the casting from the lower mold, and the vibration motor works to drive the vibration plate to knock on the lower mold, thereby making demolding smoother and preventing the electric push rod from exerting too much force on the casting, which would cause the surface of the casting to deform.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 3A high-voltage power line fitting forming device includes a workbench 1. A U-shaped fixing plate 2 is provided on one side of the top of the workbench 1. A rotating shaft 3 is rotatably connected to both ends of the U-shaped fixing plate 2. A lower mold 4 is fixedly connected between the two rotating shafts 3. A first rotating wheel 5 is rotatably connected to the outer side of the two rotating shafts 3 away from the lower mold 4. A gear 6 is fixedly connected to one end of each of the two rotating shafts 3. Two tooth blocks 7 that are adapted to the two gears 6 are fixedly connected to the top of the workbench 1. An installation groove 8 is opened on the top of the workbench 1. A wire rope net 9 is fixedly connected inside the installation groove 8. A fan 10 corresponding to the position of the wire rope net 9 is fixedly connected to the bottom of the workbench 1. During operation, the casting that detaches from the lower mold 4 falls into the top of the wire rope net 9. The fan 10 cools down the casting that has just been demolded to prevent the casting from overheating and posing a danger to the workers.

[0024] A hydraulic rod 11 is fixedly connected to one side of the workbench 1. The output end of the hydraulic rod 11 is fixedly connected to the U-shaped fixed plate 2. Driven wheels 12 are rotatably connected to both sides of the U-shaped fixed plate 2. Guide rails 13 are fixedly connected to both sides of the top of the workbench 1. The first rotating wheel 5 and the driven wheel 12 are both tumbled to the top of the guide rail 13.

[0025] The lower mold 4 has a placement groove inside, and a push plate 14 is set inside the placement groove. An electric push rod 15 is fixedly connected to the bottom of the lower mold 4. The output end of the electric push rod 15 is fixedly connected to the push plate 14. The working principle of the electric push rod is a mature existing technology, so it will not be described in detail here. When working, the electric push rod gradually increases the pushing force on the push plate 14, thereby causing the casting to separate from the inside of the mold 4.

[0026] Both sides of the lower mold 4 are rotatably connected to support wheels 16, and both sides of the top of the worktable 1 are fixedly connected to support blocks 17 that are adapted to the position of the support wheels 16.

[0027] A baffle 18 is fixedly connected to one side of the workbench 1. An inclined groove is opened inside the baffle 18. A vibrating plate 19 is slidably connected inside the groove. Limit blocks are fixedly connected to both sides of the vibrating plate 19. When the lower mold 4 moves toward the baffle 18, the mold 4 pushes the vibrating plate 19 to move upward along the inclined direction of the groove.

[0028] A vibration motor 20 is fixedly connected to the top of one end of the vibration plate 19. A spring 21 is fixedly connected to one side of the baffle 18. The other end of the spring 21 is fixedly connected to the higher end of the vibration plate 19. A button 22 is fixedly connected to one side of the baffle 18. The button 22 is electrically connected to the vibration motor 20 and the electric push rod 15. When working, the lower mold 4 is in contact with the baffle 18 and the button 22 is pressed. At this time, the vibration motor 20 and the electric push rod 15 work at the same time, so that the casting is removed from the inside of the lower mold 4.

[0029] The working principle of this utility model is as follows:

[0030] After the electrical fittings casting inside the mold is formed, the hydraulic rod 11 drives the U-shaped fixing plate 2 to move horizontally to the right of the device. When the gear 6 contacts the tooth block 7, the gear 6 and the tooth block 7 mesh together. The gear 6 is fixedly connected to the lower mold 4 through the rotating shaft 3. At this time, the movement of the U-shaped fixing plate 2 causes the tooth block 7 to drive the gear 6 to rotate, thereby causing the lower mold 4 to rotate 180 degrees. After the rotation is completed, the support wheel 16 contacts the support block 17, thereby supporting the lower mold 4 which continues to move after the rotation. At this time, the opening of the lower mold 4 corresponds to the position of the wire rope net 9. The hydraulic rod 11 continues to drive the lower mold 4 to move to the right. At this time, the right side of the lower mold 4 after the rotation contacts the baffle 18. When the lower mold 4 presses the button 22, it pushes the vibration plate 19 to move along the inclined direction of the slide. The vibration motor 20 and electric push rod 15 start working. The vibration motor 20 drives the vibrating plate 19 to vibrate. A spring 21 is fixedly connected between the higher end of the vibrating plate 19 and the baffle 18. The end of the vibrating plate 19 that contacts the lower mold 4 is always in contact with the lower mold 4 under the elastic force of the spring 21, so that the vibrating plate 19 strikes the lower mold 4. The impact force generated by the strike can produce a slight relative displacement between the lower mold 4 and the casting, breaking the tight fit and reducing surface friction, thus making demolding smoother. The electric push rod 15 pushes the formed casting, so that the surface of the casting separates from the lower mold 4 and falls onto the top of the wire rope mesh 9. Then the fan 10 works to cool the newly demolded casting. The worker picks up the cooled casting. This device uses the hydraulic rod 11 to pour the formed electrical fittings onto the top of the wire rope mesh 9 for cooling, eliminating the need for manual demolding, thereby reducing the labor intensity of the workers, improving demolding efficiency, and preventing the high-temperature casting from posing a risk to the workers.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
