Description

Technical Field

[0001] The present invention relates to the technical field of pillar porcelain insulator processing, and particularly relates to a forming mechanism and a forming machine suitable for pillar porcelain insulators. Background Art

[0002] Pillar insulators are a common insulator in rural power lines, called pillar insulators, commonly known as pillar porcelain insulators.

[0003] For example, in the patent named: A vibration cementing machine for rod-shaped insulators (patent application number: CN201821146073.1), a vibration cementing machine for rod-shaped insulators is disclosed. During cementing, the upper flange is adsorbed by an electromagnet, getting rid of the manual support operation mode of the old-fashioned cementing machine, reducing the operation intensity of workers. After the rod-shaped insulator is installed on the cementing machine, it is positioned and placed by a positioning baffle, changing the manual visual positioning method of the old-fashioned cementing machine, greatly improving the positioning accuracy and work efficiency, and at the same time greatly reducing the number of equipment inputs and production sites. The cemented products can be immediately taken offline for curing, no longer occupying the equipment for curing, greatly improving the production efficiency. Vibration is introduced during the cementing process, and the strength and quality of the cementing are also greatly improved.

[0034] The present invention provides a forming mechanism applicable to columnar porcelain insulators as Figures 1 to 7 shown, which includes a chassis 1. A positioning box 2 is arranged above the chassis 1. Two positioning boxes 2 are provided and are distributed corresponding to each other up and down, applicable to the steel flange rubber mounting forming of columnar porcelain insulators.

[0035] A vertical cylinder 13 is fixedly connected to the top of the chassis 1. Two vertical cylinders 13 are provided. A top box 14 is communicated between the tops of the two vertical cylinders 13. Fixedly connected to one end of each of the two positioning boxes 2 away from each other is a horizontal box 15. The two ends of the horizontal box 15 are respectively slidably connected to the two vertical cylinders 13. An air hole 26 is formed in the positioning box 2, and the positioning box 2 is communicated with the corresponding horizontal box 15 through the air hole 26.

[0036] The up and down movement of the horizontal box 15 drives the corresponding positioning box 2 to move synchronously, and two vertical cylinders 13 are provided to improve the stability of the movement of the horizontal box 15 and the positioning box 2.

[0037] An electric push rod 16 is arranged on one side of each of the two horizontal boxes 15 away from each other. The horizontal box 15 is fixedly connected to the telescopic end of the corresponding electric push rod 16. The electric push rod 16 located at the upper position is fixedly installed on the top box 14, and the electric push rod 16 located at the lower position is fixedly installed on the chassis 1. The horizontal box 15 is driven to move by the electric push rod 16.

[0038] Considering that vibration is introduced during the bonding process to improve the strength and quality of the bonded steel flange, if the steel flange is directly pressed into the end of the insulator through the positioning box 2 for positioning and then vibrated, the vibration will affect structures such as the positioning box 2. At the same time, clamping and fixing make it difficult for the steel flange to vibrate, affecting the vibration effect. To improve the forming effect, grooves 3 are provided at one end of the two positioning boxes 2 close to each other. Inside the groove 3, there is a rubber block 4 for fitting on the steel flange of the insulator. In the natural state, the rubber block 4 extends out of the groove 3. An inner cavity 5 is formed inside the rubber block 4, and an electromagnetic vibrator 6 is installed inside the inner cavity 5. When the electromagnetic vibrator 6 operates, it will drive the rubber block 4 to vibrate synchronously. A spring 7 is arranged inside the rubber block 4. One end of the spring 7 is fixedly connected to the rubber block 4, and the other end of the spring 7 is fixedly connected to the inner wall of the groove 3. The spring 7 can unload force and buffer, preventing structures such as the horizontal box 15 and the positioning box 2 from being affected by vibration.

[0039] On one side of the positioning box 2 close to the rubber block 4, there is a rubber pad 9 fixedly connected for fitting on the steel flange of the insulator. Between the positioning box 2 and the rubber pad 9, there is a communication component for adsorbing and fixing the steel flange of the insulator. There are multiple groups of communication components, and the multiple groups of communication components are evenly distributed around the axis of the positioning box 2.

[0040] Specifically, the communication component includes a first suction hole 8 and a second suction hole 10. The first suction hole 8 is opened at one end of the positioning box 2 close to the rubber pad 9, and the second suction hole 10 is opened on the rubber pad 9. The first suction hole 8 and the second suction hole 10 are communicated.

[0041] Inside the chassis 1, a wind power device 27 is installed. The wind power device 27 includes structures such as a fan, and the fan can switch between the suction and air supply modes. A first air pipe 17 is communicated with the horizontal box 15. One end of the first air pipe 17 away from the horizontal box 15 cooperates with the wind power device 27, and a first solenoid valve 18 is fixedly installed on the first air pipe 17.

[0042] Electromagnets 11 and magnetic blocks 12 are respectively fixedly embedded at both ends inside the rubber pad 9, and the electromagnets 11 and the magnetic blocks 12 cooperate. During specific use, a power supply device can be installed on the inner wall of the groove 3 to supply power to the electromagnets 11 and the electromagnetic vibrator 6. The power supply device includes structures such as a storage battery. The power supply device is a common existing technology and will not be elaborated here.

[0043] During actual use (taking the structures such as the positioning box 2 in the upper position as an example), after the insulator is vertically positioned, one of the steel flanges is fitted on the rubber pad 9 in the upper position. At the same time, the steel flange is fitted on the rubber block 4 and squeezes the rubber block 4 to retract into the groove 3, and the spring 7 contracts.

[0044] Control the fan to the suction mode, open the first solenoid valve 18, and use the horizontal box 15, air holes 26, positioning box 2, first suction hole 8 and second suction hole 10 to adsorb and fix the steel flange. Then close the first solenoid valve 18. The rubber pad 9 can reduce the wear between it and the steel flange, and at the same time improve the sealing performance between it and the steel flange, thereby improving the stability of the adsorption and fixation.

[0045] Furthermore, control the electromagnet 11 to repel and cooperate with the magnetic block 12. Under the action of the repulsive force, the rubber pad 9 will not deform. Control the telescopic end of the electric push rod 16 to extend, drive the horizontal box 15 and the positioning box 2 to move downward, and stably press the steel flange into the end of the insulator.

[0046] Then control the electromagnet 11 to weaken its magnetism, so that the rubber pad 9 has a certain deformation ability. Start the electromagnetic vibrator 6. At this time, the rubber block 4 is attached to the steel flange of the insulator. Use the electromagnetic vibrator 6 and the rubber block 4 to vibrate and compact the cement adhesive with the steel flange and the insulator tightly. During this process, the rubber block 4, the spring 7 and the rubber pad 9 perform force unloading and buffering to avoid the structures such as the horizontal box 15 and the positioning box 2 being affected by vibration. At the same time, the steel flange is adsorbed and fixed on the rubber pad 9. The rubber pad 9 having a certain deformation ability does not affect the vibration of the steel flange, and the vibration amplitude is controllable. After vibrating for 5 seconds and standing still for 5 minutes, take down the insulator for water bath curing and forming after the cement is basically cured.

[0047] By setting structures such as the positioning box 2 and the rubber pad 9 in the present invention, the deformation ability of the rubber pad 9 is adjustable, which cooperates with stably pressing the steel flange into the end of the insulator. At the same time, the rubber block 4, the spring 7 and the rubber pad 9 can also perform force unloading and buffering to avoid the structures such as the horizontal box 15 and the positioning box 2 being affected by vibration, and improve the use efficiency of the forming mechanism applicable to column type porcelain insulators.

[0048] Moreover, the structures such as the positioning box 2 at the upper and lower ends can be operated synchronously, and the assembly and forming of the upper and lower two steel flanges and the insulator are completed synchronously, improving the processing efficiency.

[0049] To achieve the vertical positioning of the insulator, on one side of the two vertical cylinders 13 close to each other, a cylinder 19 is communicated. A slide bar 20 is slidably connected inside the cylinder 19, and the slide bar 20 penetrates through one end of the cylinder 19 far from the vertical cylinder 13. Fixedly connected to one end of the two slide bars 20 close to each other is a clamping seat 21. A second solenoid valve 23 is fixedly installed at one end of the cylinder 19 close to the corresponding vertical cylinder 13. One of the vertical cylinders 13 cooperates with the wind power device 27. The slide bar 20 retracts into the cylinder 19, and the two clamping seats 21 move away from each other, facilitating placing the insulator between the two clamping seats 21.

[0050] The clamping seat 21 is V-shaped, and an airbag 22 is fixedly connected to the concave side of the clamping seat 21. A second air pipe 24 is communicated with the airbag 22. One end of the second air pipe 24 far away from the airbag 22 is communicated with the corresponding vertical cylinder 13, and a third solenoid valve 25 is installed on the second air pipe 24.

[0051] Considering the irregular shape of the insulator, the wall thickness on the side where the two airbags 22 are close to each other changes alternately between thick and thin. The thick part has a smaller expansion change, and the thin part has a larger expansion change. In actual use, thin-thick markings can be set on the outside of the airbag 22 for the convenience of operators.

[0052] During actual use, before fixing the insulator, start the fan in the wind power device 27 and control the fan to be in the suction mode. Open the second solenoid valve 23, and the vertical cylinder 13 and the cylinder 19 suck the sliding rod 20, so that the sliding rod 20 retracts into the interior of the cylinder 19, and the two clamping seats 21 move away from each other. Then close the second solenoid valve 23.

[0053] The operator vertically places the insulator between the two clamping seats 21, and the umbrella skirt of the insulator corresponds to the thick part on the side where the two airbags 22 are close to each other, and the position between the two umbrella skirts corresponds to the thin part. At the same time, the upper and lower ends of the insulator respectively correspond to the upper and lower positioning boxes 2. Then control the fan to switch to the air supply mode and open the second solenoid valve 23. The vertical cylinder 13 conveys gas into the interior of the cylinder 19, so that the two clamping seats 21 move towards each other, and the concave side of the clamping seat 21 fits against the outer wall of the insulator, and then close the second solenoid valve 23 to complete the preliminary positioning of the insulator. Since the clamping seat 21 is V-shaped, the insulator can be centered and maintained in a precise vertical state.

[0054] Then open the third solenoid valve 25, and the vertical cylinder 13 and the second air pipe 24 convey gas into the interior of the airbag 22. The airbag 22 expands and abuts against the outer wall of the insulator, and then close the third solenoid valve 25 to complete the final positioning of the insulator.

[0055] Since the wall thickness on the side where the two airbags 22 are close to each other changes alternately between thick and thin, and the umbrella skirt of the insulator corresponds to the thick part on the side where the two airbags 22 are close to each other, and the position between the two umbrella skirts corresponds to the thin part, that is, the expansion change at the position corresponding to the umbrella skirt is smaller, and the expansion change at the position corresponding to the space between the two umbrella skirts is larger, so as to adapt to the shape of the insulator, improve the stability of positioning, and avoid excessive extrusion of the umbrella skirt position at the same time.

[0056] The present invention also proposes a molding machine applicable to columnar porcelain insulators, which uses the above-mentioned molding mechanism applicable to columnar porcelain insulators to realize efficient molding processing.

[0057] Working principle: Start the fan in the wind power device 27 and control the fan to be in the suction mode. Open the second solenoid valve 23, and the vertical cylinder 13 and the cylinder 19 suck the slide rod 20, so that the slide rod 20 retracts into the interior of the cylinder 19, and the two clamping seats 21 move away from each other. Then close the second solenoid valve 23.

[0058] The operator vertically places the insulator between the two clamping seats 21, and the umbrella skirt of the insulator corresponds to the thick part on the side where the two air bags 22 are close to each other, and the position between the two umbrella skirts corresponds to the thin part. At the same time, the upper and lower ends of the insulator respectively correspond to the upper and lower positioning boxes 2. Then control the fan to switch to the air supply mode and open the second solenoid valve 23. The vertical cylinder 13 conveys gas into the interior of the cylinder 19, so that the two clamping seats 21 move towards each other, and the concave side of the clamping seat 21 fits on the outer wall of the insulator. Then close the second solenoid valve 23 to complete the preliminary positioning of the insulator and correct the position of the insulator to maintain an accurate vertical state. Then open the third solenoid valve 25, and the vertical cylinder 13 and the second air pipe 24 convey gas into the interior of the air bag 22. The air bag 22 expands and abuts against the outer wall of the insulator. Then close the third solenoid valve 25 to complete the final positioning of the insulator. Since the wall thickness of the side where the two air bags 22 are close to each other changes alternately between thick and thin, and the umbrella skirt of the insulator corresponds to the thick part on the side where the two air bags 22 are close to each other, and the position between the two umbrella skirts corresponds to the thin part, that is, the expansion change at the position corresponding to the umbrella skirt is small, and the expansion change at the position corresponding to the space between the two umbrella skirts is large, so as to adapt to the shape of the insulator, improve the stability of positioning, and at the same time avoid excessive extrusion of the umbrella skirt position. Then install the steel flange (taking the positioning box 2 and other structures in the upper position as an example). Take one of the steel flanges and fit it on the rubber pad 9 in the upper position. At the same time, the steel flange fits on the rubber block 4 and compresses the spring 7 to contract. Control the fan to be in the suction mode and open the first solenoid valve 18. The steel flange is adsorbed and fixed by the horizontal box 15, the air holes 26, the positioning box 2, the first suction hole 8 and the second suction hole 10. Then close the first solenoid valve 18. And control the electromagnet 11 to repel the magnetic block 12. Under the action of the repulsive force, the rubber pad 9 will not deform. Control the telescopic end of the electric push rod 16 to extend, drive the horizontal box 15 and the positioning box 2 to move downward, and press the steel flange into the end of the insulator. Then control the electromagnet 11 to weaken its magnetism, so that the rubber pad 9 has a certain deformation ability. Start the electromagnetic vibrator 6. At this time, the rubber block 4 fits on the steel flange of the insulator. Use the electromagnetic vibrator 6 and the rubber block 4 to vibrate the cement bonding agent, the steel flange and the insulator tightly. During this process, the rubber block 4, the spring 7 and the rubber pad 9 unload and buffer, avoiding the influence of vibration on the structures such as the horizontal box 15 and the positioning box 2, and at the same time not affecting the vibration of the steel flange, and the vibration amplitude is controllable. After vibrating for 5 seconds and standing still for 5 minutes, when the cement is basically cured, take down the insulator and carry out water bath curing and forming.
