Description

Technical Field

[0001] The invention relates to the field of composite insulator processing, in particular to a production system for hollow composite insulators. Background Art

[0002] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. Among them, the production of composite insulators adopts an integral injection molding process. For long-rod suspension composite insulators, due to the long structural height, general equipment cannot inject and mold the silicone rubber shed at one time, and must be spliced ​​and injected in sections. For example, if a 500T fully automatic rubber injection molding machine (equipment working part length 1500mm) is used to produce a 500kV suspension composite insulator (structural height 4900mm), it needs to be spliced ​​and molded in 4 sections. When segmenting, the traditional multi-segment molding mechanism of hollow composite insulators generally uses an integral core rod to support the inside of the bushing; a simple device is used at both ends to support the weight; and manual or electric operation is used to align the corresponding positions of the bushing and the mold to achieve multi-segment molding. The use of this mechanism requires high operator skills and high labor intensity; since personnel need to enter the molding area during the molding process and align the sleeve and the mold when the machine is turned on, there are great safety hazards; the parts that have been injection molded and the parts that have not been injection molded are in a suspended state, and the product will vibrate greatly during the process of opening and closing the mold, which can easily cause product damage, and the iron core that supports the hollow core rod is difficult to remove after molding.

At the same time, the various technical features in the invention can be combined interchangeably without conflicting with each other.

[0021] Hollow composite insulators are gradually replacing traditional porcelain insulators and stripping insulators with their superior electrical and mechanical properties, especially in ultra-high voltage or UHV transmission and transformation equipment, where the superior performance of hollow composite insulators is more evident. Existing insulators are composed of insulating core rods, silicone sheds, and connecting hardware at both ends. In the existing production process of ultra-long insulators, since the insulators have several groups of sheds on the outer surface, multiple segmented injection molding methods are required to form a complete structure during production. The main difficulty of this process in the production process is that the size of the existing injection molding machine is limited. During continuous injection, it is necessary to repeatedly open and close the mold, and at the same time, the core rod needs to be continuously moved and the iron core supporting the core rod needs to be removed.

[0022] When the hollow insulator is formed, the core rod will have fluctuations in bending strength, impact strength and thermal deformation temperature, and will shorten after subsequent secondary heating and pressurization. Therefore, it is necessary to place an iron core in the insulator core during molding. When the iron core is used in the injection mold, the core rod provides support to prevent the composite insulator core from being damaged by force during molding. In the prior art, when the insulator is produced, the iron core needs to be pulled out. During injection molding, the iron core will have a certain adhesion with the core rod, which makes it difficult to remove the iron core easily by hand, especially for extra-long insulators, where the iron core is longer and more difficult to remove.

[0023] To this end, the present invention provides an insulator production system, which is mainly aimed at the production of extra-long hollow insulators. By cleverly setting up matching lifting devices, supporting devices, etc., efficient and automated production of insulators is achieved.

[0024] Specifically, refer to Figure 1 to Figure 7The insulator production system includes an injection molding machine 100, on which a base 110 is provided, and a molding die 200 is provided in the injection molding machine 100, and the lower mold of the molding die 200 is fixed on the base 110; a lifting device 300 is provided on both sides of the base 110, and the lifting device 300 includes a workbench 310, and the workbench can move up and down relative to the base 110, and all the workbench can be lifted and lowered synchronously. A track mechanism 400 is fixed on the two workbenches 310, and the track mechanism 400 includes two long slide rails 410, and the front and rear ends of the slide rails 410 are fixed on the workbench 310, and the middle part of the slide rails 410 is located on the base 110. Similarly, the slide rails 410 can be slidably connected up and down relative to the base 110. A support device 500 is slidably arranged on the slide rail 410, and the support device 500 includes a base frame 530. The base frame 530 is slidable along the front-rear direction on the slide rail 410 through the driving unit 420. In addition, an iron core fixing seat 430 is arranged at the rear side of the track mechanism 400, and a first core rod mounting seat 510 is arranged at the front side of the base frame 530, and a second core rod mounting seat 520 is arranged at the rear side.

[0025] When working, firstly, the hollow core rod is put on the iron core, and then the iron core with the core rod is installed on the iron core fixing seat 430, and the front and rear ends of the core rod are respectively installed on the first core rod mounting seat 510 and the second core rod mounting seat 520. It can be understood that the first core rod mounting seat 510 is located in front of the lower mold, and the second core rod mounting seat 520 is located behind the lower mold. And the core rod is located in the mold cavity of the lower mold. Then the production of the composite insulator begins.

[0026] The upper die descends to close with the lower die, and then the composite material is injected to form the required shed skirt at the first section of the outer periphery of the core rod; Then the upper mold is opened, the lifting device 300 is activated, and the workbench 310 lifts the track mechanism 400 upwards, and the supporting device 500 is also lifted at the same time; since both ends of the core rod are installed on the supporting device 500, the core rod 510 is lifted together with the first section of the completed insulator; Next, the driving unit 420 drives the bottom frame 530 forward a certain distance, and the range of movement is approximately the length direction of the mold; the first section of the shed skirt that is about to be completed is transported forward, and the next section of the core rod is brought to the top of the mold cavity of the lower mold; Then, the lifting device 300 descends, driving the core rod into the cavity of the lower mold; then the upper mold descends, and the injection molding of the second section of the shed is continued; Repeat the above steps until the required length of the insulator is injection molded (for example, one mold closing injection can mold a 2.6-meter shed, and the required super-long insulator is 10 meters, which is divided into 4 injection moldings in total).

[0027] After the last section of the shed is formed, the outer circumference of the core rod is basically covered with the shed, and the finished composite insulator needs to be removed. At this time, the driving unit 420 continues to drive the base frame 530 to move forward, so that the core rod continues to move forward relative to the iron core. Since the rear end of the iron core is fixed on the iron core fixing seat 430, the core rod can be separated from the iron core as the base frame 530 continues to move forward.

[0028] After separation, the finished composite insulator is located in front of the base 110, and the iron core is left behind. At this time, the finished composite insulator only needs to be removed from the side or top. At this point, the processing and production of a single composite insulator is completed.

[0029] It can be seen that the present invention utilizes the lifting device to drive the track mechanism and the supporting device to drive the core rod to lift and lower at the same time, thereby realizing the automatic demolding and continuous production operation of the composite insulator of the product; then, through the relative sliding between the supporting device and the track mechanism, the segmented connection injection molding of the composite insulator and the automatic detachment of the iron core can be realized, thereby improving the production efficiency of the composite insulator and reducing the labor intensity of production, meeting the automated production needs of ultra-long insulators.

[0030] As mentioned above, when producing extra-long insulators, the driving unit 420 needs to drive the base frame 530 to slide on the slide rail 410 for a considerable distance (for example, in the above embodiment, when a 10-meter insulator needs to be produced, the base frame 530 needs to move 10 meters on the slide rail 410). In order to simplify the driving unit 420 and facilitate the movement of the base frame 530, further, see Figure 4 The driving unit 420 includes a motor 421 and a driving wheel 422. A rack 531 is provided on the base frame 530. The motor 421 drives the driving wheel 422 to rotate. The base frame 530 is moved forward and backward by the meshing of the driving wheel 422 and the rack 531. It can be understood that the length of the rack 531 is substantially consistent with the length of the base frame 530.

[0031] In addition, since the base frame 530 needs to move a long distance, in order to ensure that the movement of the base frame 530 on the slide rail 410 is more stable, as a further preferred embodiment, the driving unit 420 also includes a pressure wheel 423, and the base frame 530 includes a cross beam 532, the gear 531 is located directly below the cross beam 532, the pressure wheel 423 abuts against the top of the cross beam 532, and the driving wheel 422 is located below the rack 531.

[0032] It can be understood that the driving unit 420 includes a mounting base plate, which is fixed on the slide rail 410, and the motor 421 and the pressure wheel 423 are fixed on the mounting base plate. The driving shaft of the motor 421 passes through the mounting base plate and is connected to the driving wheel 422, so it is equivalent to that the driving wheel 422 is relatively fixed on the mounting base plate. Since the rack 531 is relatively fixed on the beam 532, the pressure wheel 423 is pressed against the top of the beam 532, and the driving wheel 422 is pressed against the bottom of the rack 531, so that the base frame 530 can only slide along the front and rear directions, and basically no jumping will occur in the up and down directions.

[0033] Furthermore, in order to make the bottom frame 530 more stable when moving, the slider 540 on the bottom frame 530 is optimized. The slider 540 is installed below the crossbeam 532 and fixedly connected to the crossbeam 532; the slider 540 is provided with a roller 541 and a hook 542, the roller 541 abuts against the upper surface of the slide rail 410, and the hook 542 hooks the inner surface of the slide rail 410. It can be understood that the slide rail 410 is an "I"-shaped track, and the roller 541 rolls back and forth on the upper surface of the slide rail 410, so that the roller 541 mainly supports the bottom frame 530, and the bottom frame 530 is basically restricted in the up and down direction under the action of the pressure wheel 423 and the hook 542, and then the bottom frame 530 can only be driven by the driving wheel 422 and the rack 531 to move forward and backward stably.

[0034] As mentioned above, there are two slide rails 410, and the corresponding beams 532 and racks 531 also correspond to the slide rails 410. In addition, in order to make the movement of the base frame 530 more stable, there are two groups of drive units 420, and the two groups of drive units 420 are symmetrically arranged on two different beams 532.

[0035] At the same time, since the first mandrel mounting seat 510 and the second mandrel mounting seat 520 need to drive the mandrel to move forward and backward relative to the slide rail 410 during operation, a similar slider 540 structure can be set on the first mandrel mounting seat 510 and the second mandrel mounting seat 520. By also setting the slider 540 on the first mandrel mounting seat 510 and the second mandrel mounting seat 520, the load capacity of the base frame 530 can be improved, the stress deformation of the beam 532 can be reduced, and the movement of the base frame 530 can be smoother.

[0036] As mentioned above, since the core needs to be supported by the iron core during injection molding, the length of the iron core should be greater than the length of the core rod. However, the iron core really needs to support the core rod only during injection. If the iron core is a long tube with equal diameter, the weight of the iron core will be very large and the cost will be very high in the production of super-long insulators. Therefore, as a further preferred implementation, this embodiment optimizes the structure of the iron core. See Figure 3 The iron core 10 includes a forming part 11 and a connecting part 12. The outer diameter of the connecting part 12 is smaller than the outer diameter of the forming part 11. The forming part 11 is installed and fixed at the front end of the connecting part 12. The rear end of the connecting part 12 is fixedly connected to the iron core fixing seat 430.

[0037] In this embodiment, the molding part 11 of the core 10 mainly supports the core rod 20. The length of the molding part 11 is slightly greater than the length of the mold, so that during injection molding, the molding part 11 can provide support for the core rod of the molding section. After a section of the shed is injected, the core rod 20 moves forward relatively. Since the core 10 is fixed on the track mechanism 400, the molding part 11 is immovable relative to the mold in the front-to-back direction. After the core rod 20 moves into place, the molding part 11 supports the core rod 20 of another section until the molding part 11 completes the support for all the core rods 20. In injection molding, it is only necessary to ensure that the molding part 11 is relatively immovable. Therefore, the molding part 11 can be fixed by the connecting part 12 with a smaller size. In addition, since the molding part 11 and the connecting part 12 are relatively detachable and fixedly connected, it is also convenient to replace the molding part 11 to meet the production needs of products of different specifications.

[0038] As mentioned above, since only one end of the iron core 10 is fixed relative to the track mechanism 400, and the other end is suspended. When the core rod 20 is sleeved outside the iron core 10, since both ends of the core rod 20 are relatively fixed to the track mechanism 400 through the support device 500, the iron core 10 can also obtain relatively good support. However, after the iron core 10 is separated from the core rod 20, if only the rear end of the iron core 10 is supported (and the outer diameter of the rear end is smaller), the iron core 10 is prone to tipping down and smashing the mold. For this reason, see Figure 5 As a further preferred embodiment, a support wheel seat 560 is provided on the rear end face of the second core rod mounting seat 520, and the support wheel seat 560 corresponds to the forming portion 11 of the core 10. The second core rod mounting seat 520 is provided with a through hole for the core 10 to pass through, and the support wheel seat 560 is located on the rear end face of the through hole, and the core rod 20 is located on the front end face of the through hole. When the base frame 530 moves forward, the second core rod mounting seat 520 moves forward synchronously against the core rod 20, and the core 10 moves backward relative to the second core rod mounting seat 520. When the core rod 20 is completely separated from the core 10, the front end of the core 10 is out of the cavity of the core rod 20, and at this time, the support wheel seat 560 just supports the front end of the core 10. Since the second core rod mounting seat 520 is supported on the slide rail 410 through the slider, the front end of the core 10 is prevented from falling down.

[0039] See also Figure 3 , Figure 6 In order to improve the applicability of the system, as a further preferred embodiment, a positioning rod 550 is provided on the first mandrel mounting seat 510, and a positioning head is provided on the positioning rod 550. The first mandrel mounting seat 510 includes a base plate, a mounting groove is provided on the base plate, the positioning rod 550 passes through the mounting groove, two nuts 551 are threadedly connected to the positioning rod 550, and the base plate is clamped between the two nuts.

[0040] The positioning rod 550 is in the shape of an elongated strip, and the positioning rod 550 is a threaded rod. Since the rear end of the iron core 10 is relatively fixed, and when producing different products, the relative length of the mold is different, and since the first core rod mounting seat 510 and the second core rod mounting seat 520 are relatively fixed on the base frame 530, the position of the end of the mold from the first core rod mounting seat 510 is variable. Therefore, in order to ensure that the position of the mold corresponds to the base frame 530, it is necessary to set the positioning rod 550. When the positioning head of the positioning rod 550 can fall into the positioning groove of the mold, the position of the mold and the base frame 530 is installed in place. When the length of the mold changes, by adjusting the relative installation position of the positioning rod 550, it can continue to play a positioning role.

[0041] For example, when the length of the mold shortens, the positioning head is extended relatively inward by loosening the two nuts until the positioning head reaches the positioning groove of the mold. After positioning is completed, the positioning rod 550 is relatively fixed in the new position by tightening the two nuts.

[0042] See also Figure 7As a further preferred embodiment, the lifting device 300 includes a scissor lift 320, and the workbench 310 is arranged above the scissor lift 320. The lifting device 300 also includes a pulley and a fixing rod. When producing different products, it is necessary to adjust the length of the slide rail 410, and in order to provide better support for the slide rail 410, it is necessary to adjust the relative position of the lifting device 300. By moving the lifting device 300 along the front and rear directions by the pulley, a better support position can be obtained. After the position of the lifting device 300 is adjusted, the lifting device 300 is fixed to the ground by the fixing rod.

[0043] When the track mechanism 400 needs to be lifted, the servo motor of the lifting device 300 is activated to drive the scissor lifting frame 320 to move. Under the drive of the servo motor, the two scissor arms of the scissor lifting frame 320 swing, so that the workbench 310 located above the scissor frame 320 can move up and down with the swing of the scissor arms.
