Description

TECHNICAL FIELD

[0001] The present application relates to the field of insulator manufacturing, in particular to an insulator shed and a manufacturing method thereof. BACKGROUND

[0002] The shed of the insulator is an insulating part extending from the sheath to increase the creepage distance.

[0003] In the process of manufacturing the insulator shed, a horn knife is usually used to spin the blank. The horn knife is usually about 6-8mm thick and is made of steel plate. The horn knife is made according to half of the longitudinal section geometry of the product shape that needs to be cut during spinning. The cutting edge is generally filed to an angle of 30° to 45°, and the blade thickness is about 1.5mm to 2.5mm, which is beneficial to mud removal and reduces resistance.

[0004] However, during the spinning process, the center part of the mud section is more loose in structure than the surrounding part, so it is particularly susceptible to mechanical vibration and prone to cracking. Especially when the motor or other mechanical transmission structure drives the blank to rotate, the vibration when the motor starts and stops and the centrifugal vibration generated when the blank rotates will cause excessive extrusion or contact between the blank and the horn knife, causing internal cracking of the blank. This internal cracking problem is not easy to detect from the appearance. When the insulator is fired and formed, the service life of the insulator shed with internal cracking will be greatly reduced, and the phenomenon of swelling and cracking or reduced anti-puncture ability is prone to occur.

DETAILED DESCRIPTION

[0045] The application provides an insulator umbrella skirt and a manufacturing method thereof.

[0046] Reference Figures 1 to 6 As shown in the figure, the application provides a manufacturing equipment of insulator umbrella skirt, which comprises an outer workbench 1, a rotating workbench 17, an inner workbench 29 and a horn knife 4, the outer workbench 1 and the rotating workbench 17 are both annular structures, the inner workbench 29 is a disc-shaped structure, the outer workbench 1 and the inner workbench 29 are concentrically arranged, and the rotating workbench 17 is rotationally arranged between the inner circle of the outer workbench 1 and the outer circle of the inner workbench 29.

[0047] An air pump 15 is fixedly installed on the upper surface of the inner workbench 29, a charging and air suction pipeline 16 is arranged above the air pump 15, an insulator sleeve 26 is clamped and fixed on the upper end of the charging and air suction pipeline 16, a plurality of insulator umbrella skirts 2 are uniformly arranged on the outer surface of the insulator sleeve 26, the horn knife 4 can move along the radial direction of the rotating workbench 17, the horn knife 4 is customized according to the shape of the outer surface of the insulator sleeve 26 and the insulator umbrella skirt 2, and is made of half of the longitudinal sectional geometric shape of the insulator sleeve 26 and the insulator umbrella skirt 2.

[0048] Above the insulator skirt 2, there is a motor 8 that drives the claw knife 4 to rotate along the axis of the inner worktable 29. A drive shaft 6 is fixedly installed on the shaft at the lower end of the motor 8. A driven shaft 13 is connected to the lower end of the drive shaft 6. A connecting rod 19 is fixedly installed on the lower surface of the driven shaft 13. The connecting rod 19 is connected to the claw knife 4.

[0049] In this invention, the driving shaft 6 and the driven shaft 13 are driven by magnetic adsorption (magnetic shaft mechanism), which do not come into contact with each other, resulting in quiet operation and minimal impact from vibration.

[0050] For details, please refer to Figure 7 As shown, an electromagnet 31 is fixedly installed at the lower inner ring of the drive shaft 6. At least four electromagnets 31 are provided, and the four electromagnets 31 are distributed at equal angles along the axis of the drive shaft 6. The upper end of the driven shaft 13 extends into the interior of the drive shaft 6. A magnetic block 30 is fixedly installed at the upper outer ring of the driven shaft 13. The number of magnetic blocks 30 is matched with the number of electromagnets 31. When the motor 8 drives the drive shaft 6 to rotate, the attraction force between the electromagnets 31 and the magnetic blocks 30 drives the driven shaft 13 to rotate. When the driven shaft 13 rotates, it drives the horn cutter 4 to rotate through the connecting rod 19, thereby causing the horn cutter 4 to rotate around the axis of the insulator skirt 2 to spin the blank and shape the blank.

[0051] In summary, this invention solves the problem of internal cracking of the insulator skirt 2 caused by vibration during motor start-up and shutdown by using magnetic adsorption for transmission.

[0052] refer to Figure 4 , Figure 6 and Figure 9 As shown, the ram's horn knife 4 in this invention is pushed close to and attached to the surface of the insulator skirt 2 by a combination of electric push rod and air source, which can reduce the problem of internal cracking of the insulator skirt 2 caused by vibration when the equipment is started and stopped.

[0053] During the turning process, the first step is to bring the horn cutter 4 close to the outer ring of the blank. At this time, the electric push rod 32 is used to drive the horn cutter 4 to approach the insulator skirt 2. When the horn cutter 4 approaches the insulator skirt 2 to a certain distance, such as about 1 cm, the expansion of the rubber air bag 37 is used to drive the horn cutter 4 to continue to approach the outer ring of the insulator skirt 2 until the horn cutter 4 is in contact with the outer ring of the insulator skirt 2.

[0054] Specifically, in this invention, a sliding groove 25 is provided on the upper surface of the rotating worktable 17. An electric push rod 32 is fixedly provided on the inner wall of one end of the sliding groove 25. A sliding support rod 24 is fixedly connected to the end of the electric push rod 32. A control box 3 is fixedly provided at the upper end of the sliding support rod 24. A rectangular groove 41 is provided inside the control box 3. A rubber airbag 37 is provided inside the rectangular groove 41. A connecting plate 40 is fixedly provided on the surface of the rubber airbag 37. The end of the connecting plate 40 away from the rubber airbag 37 extends out of the rectangular groove 41 and is fixedly connected to the claw knife 4. When the electric push rod 32 is activated, the sliding support rod 24, the control box 3, and the claw knife 4 simultaneously move closer to the insulator skirt 2. When the rubber air bladder 37 is inflated, the gas causes the rubber air bladder 37 to expand in the rectangular groove 41, thereby causing the claw knife 4 to continue to move closer to the insulator skirt 2. Because the gas-driven method has good buffering and adaptability, the claw knife 4 will not impact the outer surface of the insulator skirt 2 and cause vibration when it initially contacts the insulator skirt 2, thus avoiding the phenomenon of cracking inside the insulator skirt 2.

[0055] Furthermore, in this invention, an air pipe 22 is provided above the control box 3, and the lower end of the air pipe 22 is connected to the interior of the rubber air bag 37. An inflation / inhalation pipe 16 is provided at the upper end of the air pump 15, and a stepped surface 36 is provided at the outer ring of the inflation / inhalation pipe 16. The lower end of the insulator sleeve 26 is engaged and fixed on the stepped surface 36. A second connecting pipe 35 is connected to the inflation / inhalation pipe 16 by a threaded connection, and a first connecting pipe 21 is connected to the air pipe 22 by a threaded connection. A U-shaped connecting pipe 5 is provided between the first connecting pipe 21 and the second connecting pipe 35. The ends of the second connecting pipe 35 and the first connecting pipe 21 are rotatably connected to the corresponding ends of the U-shaped connecting pipe 5.

[0056] During operation, the air pump 15 can be started, and the gas is sequentially delivered to the rubber air bag 37 after passing through the inflation and suction pipe 16, the second connecting pipe 35, the U-shaped connecting pipe 5, the first connecting pipe 21, and the air pipe 22. When the claw cutter 4 rotates around the axis of the insulator skirt 2, the end of the U-shaped connecting pipe 5 rotates at the upper end of the second connecting pipe 35. Therefore, based on the arrangement of the U-shaped connecting pipe 5, the second connecting pipe 35, and the first connecting pipe 21, the rubber air bag 37 can be supplied with air without affecting the rotation and processing of the claw cutter 4. This solves the problem that the air pump 15 needs to be fixedly installed on the claw cutter 4 in the prior art, and reduces the phenomenon that the claw cutter 4 cannot rotate stably or that the centrifugal force is too large due to weight issues.

[0057] Furthermore, the U-shaped connecting pipe 5 has a directional force that pulls the ram's horn 4 towards the outer ring of the insulator skirt 2, maintaining the stable rotation of the ram's horn 4 and preventing excessive centrifugal force; the U-shaped connecting pipe 5 can also prevent the insulator skirt 2 from detaching from the air inlet / outlet pipe 16, avoiding the problem of accidental detachment.

[0058] Furthermore, in this invention, the air pump 15 can buffer the inflation of the rubber air bag 37, and the air volume is easy to control. Therefore, the scissor 4 can gradually approach the insulator skirt 2, without causing the scissor 4 to directly and excessively press against the outer ring of the insulator skirt 2 in the initial process.

[0059] In actual use, a horizontally arranged spring 38 is installed inside the rubber airbag 37. The two ends of the spring 38 are fixedly connected to the inner walls of the two ends of the rubber airbag 37. When the air pump 15 extracts the gas inside the rubber airbag 37, the spring 38 can pull the rubber airbag 37 back to its original position due to its pulling action, thereby causing the scalpel 4 to also return to its original position.

[0060] In this invention, a pressure sensor 39 is installed inside the rubber air bladder 37. The pressure sensor 39 can monitor the gas pressure inside the rubber air bladder 37. When the rubber air bladder 37 is inflated so that the claw blade 4 is attached to the outer ring of the insulator skirt 2, the amount of gas inside the rubber air bladder 37 remains constant. As the claw blade 4 rotates along the outer ring of the insulator skirt 2, if the claw blade 4 can rotate stably, the gas pressure monitored by the pressure sensor 39 will not change. If there are protrusions or depressions on the outer surface of the blank, the claw blade 4 will move left and right accordingly, causing the gas pressure inside the rubber air bladder 37 to change. Therefore, by monitoring the pressure changes inside the rubber air bladder 37 through the pressure sensor 39, it is possible to determine whether the outer ring of the insulator skirt 2 meets the production requirements based on the pressure fluctuations.

[0061] Furthermore, when cracks appear inside the blank, the internal structure of the blank becomes more porous. Since the rubber air bladder 37 is inflated and constantly presses against the claw knife 4 against the outer ring of the insulator skirt 2, when the internal structure of the insulator skirt 2 becomes more porous, the claw knife 4 will increase the pressing force on the insulator skirt 2, which will cause the pressure monitored by the pressure sensor 39 to change. Therefore, by monitoring the pressure fluctuation inside the rubber air bladder 37 through the pressure sensor 39, it is also possible to determine whether there are problems such as cracks inside the insulator skirt 2.

[0062] Remanufacturing defective blanks will significantly increase the quality of the insulator skirt 2.

[0063] In summary, by using an electric push rod and a pneumatic source to drive the horn knife 4 to approach and adhere to the surface of the insulator skirt 2, the phenomenon of internal cracking of the insulator skirt 2 can be reduced. In this invention, by combining the pneumatic source with the real-time monitoring of the gas pressure inside the rubber air bladder 37 by the pressure sensor 39, the quality problems of the inner and outer surfaces of the insulator skirt 2 can be determined.

[0064] In actual use, a connecting rod 19 is fixedly connected to the lower end of the driven shaft 13, and a spring telescopic rod 20 is installed at the end of the connecting rod 19. A connecting plate 14 is fixedly connected to the end of the spring telescopic rod 20 away from the connecting rod 19, and the lower end of the connecting plate 14 is fixedly connected to one side of the control box 3. When the claw knife 4 moves, the spring telescopic rod 20 will extend and retract accordingly.

[0065] refer to Figure 8 As shown, a rotating groove 34 is formed between the outer ring of the inner worktable 29 and the inner ring of the outer worktable 1. The rotating worktable 17 is rotatably disposed in the rotating groove 34. Limiting rings 23 are fixedly connected to the upper and lower surfaces of the outer ring of the inner worktable 29 and the inner ring of the outer worktable 1. The limiting rings 23 are movably fitted to the upper or lower surface of the rotating worktable 17. The outer ring and the upper and lower surfaces of the rotating worktable 17 are movably embedded with balls 33. When the rotating worktable 17 rotates in the rotating groove 34, the balls 33 contact the outer worktable 1, the inner worktable 29 or the limiting rings 23, and the rotation is smooth. The limiting rings 23 have the function of limiting the rotation of the rotating worktable 17, so that the rotating worktable 17 and the claw knife 4 can rotate stably around the axis of the inner worktable 29 and are not prone to centrifugal force.

[0066] refer to Figure 1 and Figure 3 As shown, both the outer workbench 1 and the inner workbench 29 of the present invention are fixedly mounted with bottom brackets 12. The bottom brackets 12 connect the outer workbench 1 and the inner workbench 29, so that the whole can stably support the insulator skirt 2.

[0067] A motor disk 9 is fixedly installed on the upper surface of the motor 8. An outer bracket 7 is fixedly installed on the outer ring of the motor disk 9. The lower end of the outer bracket 7 rests on the ground, thus supporting the motor 8.

[0068] refer to Figure 1 , Figure 2 and Figure 4 As shown, the connecting rod 19 has a cross-shaped structure. One end of the connecting rod 19 is connected to the connecting plate 14, and the other three ends of the connecting rod 19 are fixedly connected to the stabilizing bracket 18. The stabilizing bracket 18 is fixedly connected to the upper surface of the rotating worktable 17, which can make it more stable when the motor 8 drives the claw knife 4 to rotate.

[0069] refer to Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, two coils of energizing coil 27 are provided on the outer ring of the drive shaft 6. The two ends of the energizing coil 27 are respectively connected to the positive and negative poles of the electromagnet 31. A battery box 10 is fixedly installed on the upper surface of the motor disk 9. The battery box 10 stores a lithium battery. A busbar groove 11 is provided on the lithium battery. Two electrode plates 28 are provided at the end of the busbar groove 11. The two electrode plates 28 are respectively connected to the positive and negative poles of the lithium battery. The ends of the two electrode plates 28 away from the busbar groove 11 are movably attached to the corresponding energizing coil 27.

[0070] In this invention, the magnetism of electromagnet 31 is adjustable. Specifically, different strengths of magnetism are generated depending on the amount of current supplied to electromagnet 31 by the lithium battery. Therefore, the magnetism of electromagnet 31 can be appropriately adjusted according to the stability of the rotating claw knife 4, thereby increasing the transmission effect and stability between the driving shaft 6 and the driven shaft 13. This adjustment can be made according to actual needs, solving the problem of difficulty in controlling and adjusting the centrifugal stability of rotating objects in the prior art.

[0071] Furthermore, the electrode plate 28 and the coil 27 are directly and dynamically attached. When the claw cutter 4 rotates, if excessive centrifugal force is generated, the entire claw cutter 4 will move towards the outer ring of the insulator skirt 2, thereby increasing the degree of shaking of the drive shaft 6 and causing poor contact between the coil 27 and the electrode plate 28. When poor contact occurs, the motor 8 can be stopped by the existing circuit breaker, so that the claw cutter 4 stops rotating, avoiding the quality impact on the billet caused by excessive centrifugal force generated by the claw cutter 4. After the impact is resolved by maintenance, the billet can continue to be processed, reducing the scrap rate of the billet.

[0072] It should be noted that the battery box 10 in this invention is equipped with a flow regulating valve, which is used to regulate the flow rate of the lithium battery. This is a common existing technology and will not be described in detail here.

[0073] It should also be noted that in this invention, the battery box 10 is installed on the motor disk 9. By setting the electrode plate 28 and the coil 27, the purpose of adjusting the magnetic strength of the rotating shaft component can be achieved without setting the battery box 10 on the rotating shaft component, without affecting the rotation of the rotating shaft component, and the equipment can be stopped when the centrifugal force of the claw knife 4 is too large; the rotating shaft component has a small counterweight, making it more stable and energy-saving.

[0074] The rotating shaft component proposed in this invention refers to a rotatable mechanism, such as the driving shaft 6 and the driven shaft 13.

10. A method for manufacturing an insulator skirt, characterized in that: The insulator skirt applicable to any one of claims 1-9 further includes the following steps: S1: Prepare a horn knife (4) made from half of the longitudinal cross-sectional geometry of the insulator sleeve (26) and the insulator skirt (2). A motor (8) is installed above the horn knife (4). The motor (8) and the horn knife (4) are driven by a magnetic shaft mechanism. The motor (8) drives the horn knife (4) to rotate around the axis of the insulator skirt (2) through the magnetic shaft mechanism. The magnetic shaft mechanism blocks the vibration force of the motor (8) when it starts from being transmitted to the horn knife (4). S2: Drive the horn knife (4) close to the insulator skirt (2), and drive the horn knife (4) to rotate by combining the electric push rod and the air source; First, push the horn knife (4) close to the insulator skirt (2) with the electric push rod (32) until the distance between the two is about 1 cm. Then, use the air source to push the horn knife (4) to continue moving until the horn knife (4) is in contact with the surface of the insulator skirt (2). S3: When the ram's horn knife (4) rotates around the insulator skirt (2), when there are protrusions, depressions or cracks on the outer surface or inside of the insulator skirt (2), the rubber airbag (37) pushes the ram's horn knife (4) away from or closer to the insulator skirt (2). At this time, the air pressure inside the rubber airbag (37) changes, and the pressure sensor (39) set inside the rubber airbag (37) feeds back the pressure data to the computer terminal in real time.
