Description

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware.

[0003] Currently, insulator production requires crimping the ends of the insulator rods and installing umbrella-shaped sheaths on them. However, with existing processing equipment, the surface of the insulator rods will bulge after crimping. During subsequent injection molding of the umbrella-shaped sheaths, gaps can easily form at the injection cavity engagement point, leading to leakage. Summary of the Invention

[0011] Preferably, the injection molding device includes an umbrella-shaped injection cavity, which is opened inside the clamping arm, and one side of the umbrella-shaped injection cavity extends to one side of the clamping arm. The umbrella-shaped injection cavity is interconnected with the guide rail. A cylindrical cavity is opened inside the clamping arm, and an injection hole is opened inside the clamping arm. One end of the injection hole extends into the interior of the umbrella-shaped injection cavity, and the other end of the injection hole extends into the interior of the cylindrical cavity.

[0012] Preferably, a storage tube is fixed to the top of the clamping arm, and a feed hole is opened at the bottom of the storage tube.

[0013] Preferably, both ends of the cylindrical slider are fixed with guide rods, one end of one guide rod slides through the interior of the guide groove, and the other guide rod slides through the interior of the injection hole, with the outer surface of the guide rod in contact with the inner wall of the injection hole.

[0015] The present invention also provides an insulator manufacturing process, applied to an insulator manufacturing apparatus, the insulator manufacturing process comprising the following steps:

[0016] Step S1: Place the insulator rod between the turntable and the support plate, and engage it through the annular grooves on the turntable and the support plate. Then, it is conveyed to the clamping channel on the clamping arm. When the turntable rotates, the boss strip pushes one end of the clamping arm outward, thereby engaging the other end of the clamping arm with each other, thus engaging the insulator rod conveyed into the clamping channel. During engagement, the ferrule engages with the insulator rod, and at the same time, the feeding component is triggered, which also drives the injection molding device to perform umbrella-shaped outer sleeve injection molding on the insulator rod.

[0017] Step S2: When the drive assembly is working, the insulator rod can be conveyed forward by the opposite rotation of the turntable and the support plate, while the two clamping arms are driven to open and close. When the clamping arms are driven to open and close, the boss strip pushes one end of the clamping arm outward, so that the two clamping arms can be clamped together.

[0018] Step S3: When the feeding assembly is working, after the clamping arm opens, the ferrule originally located inside the storage frame falls into the engagement cavity, and the ferrule at the bottom inside the storage frame enters the material conveying frame. As the two clamping arms separate, the material conveying frame is pushed outward to the position where it protrudes halfway from the clamping arm under the action of the elastic force of the second spring. This cycle is repeated to complete the function of intermittently feeding the ferrule.

[0019] Step S4: When the injection molding device is working, after the two clamping arms are engaged with each other, when the material conveying frame is pushed into the transmission box, it will drive the guide blocks on both sides of the material conveying frame to slide inside the guide groove. When the guide block slides to one end of the guide rod extending into the guide groove, it will push the guide rod into the cylindrical cavity. During the pushing process, it will drive the cylindrical slider to slide until the side opening is opposite to the inlet hole. At this time, the molten plastic inside the storage tube can enter the buffer cavity through the side opening, and then enter the injection hole through the through hole from the inside of the buffer cavity, and enter the umbrella-shaped injection cavity from the injection hole. Since the umbrella-shaped injection cavity is connected to the clamping channel, an umbrella-shaped outer sleeve can be formed on the outer surface of the insulator rod.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention can transport the insulator rod to the clamping track on the two clamping arms by setting a driving component, and drive the two clamping arms to open and close. While the two clamping arms are closing and opening, the ferrule is transported intermittently by the feeding component. While the feeding component is working, the injection molding device is also triggered to perform umbrella-shaped outer sleeve injection molding on the outer surface of the insulator rod.

[0022] 2. By setting up a driving component, the opposite rotation of the turntable and the support plate can drive the insulator rod to be conveyed forward while driving the opening and closing of the two clamping arms. When driving the clamping arms to open and close, the boss strip pushes one end of the clamping arm outward, so that the two clamping arms can be clamped together.

[0023] 3. By setting up a feeding component, after the clamping arm is opened, the ferrule originally located inside the storage frame falls into the engagement cavity, and the ferrule at the bottom inside the storage frame enters the material conveying frame. As the two clamping arms separate, the material conveying frame is pushed outward to a position where it protrudes halfway from the clamping arm under the action of the elastic force of the second spring. This cycle is repeated to complete the function of intermittently feeding the ferrule.

[0024] 4. In this invention, through the injection molding device, the molten plastic inside the storage tube enters the buffer chamber through the side opening, and then enters the injection hole through the through hole from the inside of the buffer chamber, and enters the umbrella-shaped injection cavity from the injection hole. Since the umbrella-shaped injection cavity is connected to the channel, an umbrella-shaped outer sleeve can be formed on the outer surface of the insulator rod. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8 The present invention provides a technical solution: an insulator production device, including a fixed frame 1, two clamping arms 2 are arranged on the inner side of the fixed frame 1, each clamping arm 2 is provided with a rotating shaft 3, the two rotating shafts 3 are rotatably connected to the inner bottom surface of the fixed frame 1, one end of each clamping arm 2 is provided with an arc-shaped block 14, and a drive assembly for driving the clamping arms 2 to move is arranged inside the fixed frame 1.

[0036] One side of each of the two clamping arms 2 is inclined. A first spring 4 is fixed on the inclined surface of each of the two clamping arms 2. One end of each of the two first springs 4 is fixed on the inner arm of the fixing frame 1. A feeding assembly is provided on each of the two clamping arms 2. An injection molding device is provided inside each of the two clamping arms 2. A slot 22 is opened on the opposite side of each of the two clamping arms 2. The slot 22 extends through to both sides of the clamping arm 2.

[0037] The effect achieved is that by setting the drive assembly, the insulator rod can be conveyed to the clamping track 22 on the two clamping arms 2, and the two clamping arms 2 can be driven to open and close. While the two clamping arms 2 are closing and opening, the feeding assembly delivers the ferrule 15 intermittently. At the same time as the feeding assembly is working, the injection molding device is also triggered to perform umbrella-shaped outer sleeve injection molding on the outer surface of the insulator rod. By fixing the first spring 4 on the inclined surface of the clamping arm 2, elastic pressure can be provided to the clamping arm 2, so that the arc block 14 part always slides and fits against the outer surface of the turntable 6, which facilitates the reset of the clamping arm 2 in the subsequent reset.

[0038] like Figure 1 and Figure 2 As shown, the drive assembly includes a turntable 6. A first drive shaft 5 is rotatably connected between the inner walls of the two sides of the fixed frame 1 near the top edge. The turntable 6 is fixed on the first drive shaft 5 and located in the middle. A second drive shaft 12 is rotatably connected between the inner walls of the two sides of the fixed frame 1 near the bottom edge. A support plate 13 is fixed on the outer surface of the second drive shaft 12 at the middle. The support plate 13 is located below the turntable 6. Both the outer surfaces of the turntable 6 and the support plate 13 are provided with annular grooves 8. The openings of the annular grooves 8 on the outer surfaces of the turntable 6 and the support plate 13 are opposite to each other. Both outer surfaces of the turntable 6 are fixed with boss strips 7 near the edges. The two boss strips 7 are respectively attached to the arc-shaped block 14.

[0039] The effect achieved is that by rotating the turntable 6 and the support plate 13 in opposite directions, the insulator rod can be conveyed forward while the two clamping arms 2 are driven to open and close. When the clamping arms 2 are driven to open and close, the boss strip 7 pushes one end of the clamping arm 2 outward, so that the two clamping arms 2 can be clamped together.

[0040] like Figure 1 , Figure 3 and Figure 6As shown, the feeding assembly includes a conveying frame 17, a transmission box 11 fixed to the outer surface of one side of the clamping arm 2, a reciprocating cavity 25 opened on one side of the clamping arm 2, the reciprocating cavity 25 and the guide 22 penetrating through each other, the reciprocating cavity 25 penetrating to the opening of the transmission box 11, the conveying frame 17 slidably connected between the inner walls of the two sides of the transmission box 11, the inner walls of both sides of the transmission box 11 are provided with guide grooves 19, and guide blocks 20 are fixed on both sides of the conveying frame 17, the two guide blocks 20 being slidably connected to the inside of the guide grooves 19 respectively. A second spring 18 is fixed to the rear side of the material frame 17. One end of the second spring 18 is fixed to the inner wall of the transmission box 11. A storage frame 10 is fixed to the top of the clamping arm 2 near the top of the guide 22. A locking cavity 16 is opened inside the clamping arm 2. One side of the locking cavity 16 extends into the interior of the guide 22. The bottom of the storage frame 10 extends into the interior of the locking cavity 16. The storage frame 10 and the transmission box 11 are interconnected. Multiple sleeves 15 are provided inside the storage frame 10. An arc-shaped opening 24 is opened on one side of each sleeve 15.

[0041] The effect achieved is as follows: when the two clamping arms 2 are in the open state, the material conveying frame 17 is lifted outward to half of the position protruding from the clamping arms 2 under the elastic force of the second spring 18. At this time, there is a ferrule 15 inside the material conveying frame 17. When the two clamping arms 2 are clamped together, one end of the material conveying frame 17 on the two clamping arms 2 pushes against each other, causing it to slide into the transmission box 11. At this time, the material conveying frame 17 is opposite to the bottom opening of the storage box 10, so that the ferrule 15 inside the storage box 10 can be transported to the material conveying frame 17 for storage. After the clamping arms 2 are opened, the ferrule 15 originally located inside the storage box 10 falls into the engagement cavity 16. The ferrule 15 at the bottom inside the storage box 10 enters the material conveying frame 17. As the two clamping arms 2 separate, the material conveying frame 17 is lifted outward to half of the position protruding from the clamping arms 2 under the elastic force of the second spring 18. This cycle is repeated to complete the function of intermittently feeding the ferrule 15.

[0042] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the injection molding device includes an umbrella-shaped injection cavity 21, which is located inside the clamping arm 2. One side of the umbrella-shaped injection cavity 21 extends to one side of the clamping arm 2. The umbrella-shaped injection cavity 21 is connected to the guide rail 22. A cylindrical cavity 26 is formed inside the clamping arm 2. An injection hole 23 is formed inside the clamping arm 2. One end of the injection hole 23 extends into the umbrella-shaped injection cavity 21, and the other end extends into the cylindrical cavity 26. A storage tube 9 is fixed to the top of the clamping arm 2. A feed hole 33 is formed at the bottom of the storage tube 9 and extends into the cylindrical cavity 26. A cylindrical slider 27 is slidably connected between the inner walls of the cylindrical cavity 26. A buffer cavity 28 is provided, and multiple side openings 30 are equidistantly provided on the inner wall of the buffer cavity 28 along the circumferential direction. All the side openings 30 extend to the outer side of the cylindrical slider 27. Guide rods 29 are fixed at both ends of the cylindrical slider 27. One end of one guide rod 29 slides through the interior of the guide groove 19, and the other guide rod 29 slides through the interior of the injection hole 23. The outer surface of the guide rod 29 is in contact with the inner wall of the injection hole 23. A through hole 31 is provided on one side of the inner wall of the buffer cavity 28. The through hole 31 extends through one end of the guide rod 29 and communicates with the injection hole 23. A third spring 32 is fixed on one side of the cylindrical slider 27. One end of the third spring 32 is fixed on one side of the inner wall of the cylindrical cavity 26.

[0043] The effect achieved is that after the two clamping arms 2 engage with each other, when the material conveying frame 17 is pushed into the transmission box 11, the guide blocks 20 on both sides of the material conveying frame 17 will slide inside the guide groove 19. When the guide block 20 slides to one end of the guide rod 29 extending into the guide groove 19, it will push the guide rod 29 into the cylindrical cavity 26. During the pushing process, the cylindrical slider 27 will slide until the side opening 30 is opposite to the inlet hole 33. At this time, the molten plastic inside the storage tube 9 can enter the buffer cavity 28 through the side opening 30, and then enter the injection hole 23 through the through hole 31 from the inside of the buffer cavity 28. From the injection hole 23, it enters the umbrella-shaped injection cavity 21. Since the umbrella-shaped injection cavity 21 and the clamping channel 22 are connected, an umbrella-shaped outer sleeve can be formed on the outer surface of the insulator rod.

[0044] The main problem solved by this embodiment is that by setting a driving component, the insulator rod can be conveyed to the slot 22 on the two clamping arms 2, and the two clamping arms 2 can be driven to open and close. While the two clamping arms 2 are closing and opening, the ferrule 15 is conveyed intermittently by the feeding component. While the feeding component is working, the injection molding device will also be triggered to perform umbrella-shaped outer sleeve injection molding on the outer surface of the insulator rod.

[0045] For example, in one embodiment, the present invention also provides an insulator manufacturing process applied to an insulator manufacturing apparatus as described above, comprising the following steps:

[0046] Step S1: The insulator rod is placed between the turntable 6 and the support plate 13, and is engaged by the annular groove 8 on the turntable 6 and the support plate 13. Then it is conveyed to the clamping channel 22 on the clamping arm 2. When the turntable 6 rotates, the boss strip 7 pushes one end of the clamping arm 2 outward, so that the other end of the clamping arm 2 engages with each other, thereby engaging the insulator rod conveyed to the clamping channel 22. When engaging, the sleeve 15 is engaged on the insulator rod, and the feeding component is triggered, which also drives the injection molding device to perform umbrella-shaped outer sleeve injection molding on the insulator rod.

[0047] Step S2: When the drive assembly is working, the insulator rod can be driven forward by the opposite rotation of the turntable 6 and the support plate 13, while the two clamping arms 2 are driven to open and close. When the clamping arms 2 are driven to open and close, the boss strip 7 pushes one end of the clamping arm 2 outward, so that the two clamping arms 2 can be clamped together.

[0048] Step S3: When the feeding assembly is working, after the clamping arm 2 opens, the sleeve 15 that was originally located inside the storage box 10 falls into the engagement cavity 16. The sleeve 15 at the bottom inside the storage box 10 enters the material conveying frame 17. As the two clamping arms 2 separate from each other, the material conveying frame 17 is pushed outward to the position where it protrudes half of the clamping arm 2 under the action of the elastic force of the second spring 18. This cycle is repeated to complete the function of intermittently feeding the sleeve 15.

[0049] Step S4: When the injection molding device is working, after the two clamping arms 2 are engaged with each other, when the material conveying frame 17 is pushed into the transmission box 11, it will cause the guide blocks 20 on both sides of the material conveying frame 17 to slide inside the guide groove 19. When the guide block 20 slides to one end of the guide rod 29 extending into the guide groove 19, it will push the guide rod 29 into the cylindrical cavity 26. During the pushing process, it will drive the cylindrical slider 27 to slide until the side opening 30 is aligned with the inlet hole 33. At this time, the molten plastic inside the storage tube 9 can enter the buffer cavity 28 through the side opening 30, and then enter the buffer cavity 28 through the through hole 31. Inside the injection hole 23, the material enters the umbrella-shaped injection cavity 21. Since the umbrella-shaped injection cavity 21 and the locking channel 22 are connected, an umbrella-shaped outer sleeve can be formed on the outer surface of the insulator rod. This processing method of the umbrella-shaped outer sleeve can avoid the problem that when the existing processing equipment processes the insulator, the surface of the insulator rod will be convex after crimping. During the subsequent injection molding of the umbrella-shaped sleeve, gaps are easily generated at the locking point of the injection cavity, which can lead to leakage. At the same time, the cooperation with the feeding component during the production process can make the entire process of processing the insulator rod more compact and improve the overall production efficiency.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

When the turntable (6) rotates, push one end of the clamping arm (2) outward through the boss strip (7), so that the other end of the clamping arm (2) engages with each other, thereby engaging the insulator rod transported to the clamping channel (22). When engaging, the sleeve (15) is engaged on the insulator rod, and the feeding component is triggered, which will also drive the injection molding device to perform umbrella-shaped outer sleeve injection molding on the insulator rod. Step S2: When the drive assembly is working, the insulator rod can be driven forward by the opposite rotation of the turntable (6) and the support plate (13), while the two clamping arms (2) are driven to open and close. When the clamping arms (2) are driven to open and close, one end of the clamping arm (2) is pushed outward by the boss strip (7), so that the two clamping arms (2) can be clamped together. Step S3: When the feeding assembly is working, after the clamping arm (2) is opened, the sleeve (15) that was originally located inside the storage box (10) falls into the inside of the engagement cavity (16). The sleeve (15) at the bottom inside the storage box (10) enters the inside of the conveying frame (17). As the two clamping arms (2) separate from each other, the conveying frame (17) is pushed outward to the position where it protrudes half of the clamping arm (2) under the action of the elastic force of the second spring (18). This cycle is repeated to complete the function of intermittently feeding the sleeve (15). Step S4: When the injection molding device is working, after the two clamping arms (2) are engaged with each other, when the material conveying frame (17) is pushed into the transmission box (11), the guide blocks (20) on both sides of the material conveying frame (17) will slide inside the guide groove (19). When the guide block (20) slides to one end of the guide rod (29) extending into the guide groove (19), it will push the guide rod (29) into the cylindrical cavity (26). During the pushing process, the cylindrical slider (2) will be driven. 7) Slide until the side opening (30) is opposite to the feed hole (33). At this time, the molten plastic inside the storage tube (9) can enter the buffer cavity (28) through the side opening (30), and then enter the injection hole (23) through the through hole (31) from the inside of the buffer cavity (28). Then, it enters the umbrella-shaped injection cavity (21) from the injection hole (23). Since the umbrella-shaped injection cavity (21) and the channel (22) are connected, an umbrella-shaped outer sleeve can be formed on the outer surface of the insulator rod.
