DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The present invention provides Figure 1 A method for manufacturing a composite tension insulator is shown, comprising the following steps:

[0043] S1. Loading: The steel is preheated to achieve the effects of cleaning, heating, straightening and heat preservation, and then enters the bending station to improve manufacturing efficiency;

[0044] S2, Bending: Cut the heated steel and then extrude it to complete the bending process of the steel;

[0045] S3, unloading: The U-shaped ring formed by preheating and bending slides down to unload, realizing continuous production;

[0046] S4. Assembly: Take two U-shaped rings and butt them with the insulator to form a finished composite tension insulator.

[0047] The present invention also provides Figure 2 to Figure 11 A composite tension insulator manufacturing device shown uses the above-mentioned composite tension insulator manufacturing method, including a chassis 1, on which a cutting device 29 and a bending device 28 are fixedly arranged. The cutting device 29 includes a cylinder, a cutter and other structures, which are used to cut the conveyed steel for easy bending; the bending device 28 includes a cylinder, a U-shaped pressing block and other structures, which squeeze the cut steel into a U-shaped ring. The cutting device 29 and the bending device 28 are both existing technologies and are not described here. A discharge plate 27 is fixedly connected to the chassis 1, which is used for the U-shaped ring to slide down and discharge after bending and forming; when it is used specifically, a mechanical arm can be set to cooperate with the discharge to realize automated production.

[0048] Considering that the existing composite tension insulator manufacturing equipment generally does not preheat the steel during the bending process, the steel is often subjected to excessive or uneven force when being bent, causing the steel to break and pop out, which is easy to cause personal injury to the staff and reduce work efficiency. In order to achieve the preheating treatment of the steel, a first rotating tube 5 for suction is rotatably arranged above the chassis 1. The first rotating tube 5 is arranged in multiple numbers, and the multiple first rotating tubes 5 are distributed in a horizontal straight line and move synchronously up and down. A second rotating tube 6 for conveying high-temperature gas is rotatably arranged below the first rotating tube 5. The ends of the first rotating tube 5 and the second rotating tube 6 are both connected to a guide cylinder 11, and an annular groove 14 is provided on the outer ring of the guide cylinder 11. A heating zone for the steel to pass through is formed between the upper and lower annular grooves 14. A ventilation assembly is provided on the inner wall of the annular groove 14 , and the ventilation assembly includes two ventilation grooves 17 . The ventilation grooves 17 are opened on the inner wall of the annular groove 14 . The ventilation grooves 17 are connected to the guide cylinder 11 , and the two ventilation grooves 17 are respectively located on both sides of the annular groove 14 .

[0049] Specifically, high-temperature gas is sprayed toward the steel from the guide cylinder 11 and the ventilation slots 17 in the lower position, so that a high-temperature airflow is formed in the heating zone to preheat the steel, facilitate bending and deformation, reduce the internal stress generated by the steel during bending, and prevent quality problems such as deformation or cracks in the steel due to bending; at the same time, the guide cylinder 11 and the ventilation slots 17 in the upper position suck the sprayed gas, and the high-temperature gas flows in the steel to realize high-temperature gas circulation and avoid heat waste.

[0050] At the same time, when the high-temperature gas is sprayed toward the steel from the guide cylinder 11 and the ventilation slot 17 at the lower position, the impurities can be blown away; at the same time, the impurities are sucked away by the guide cylinder 11 and the ventilation slot 17 at the upper position, and the blowing and suction are carried out simultaneously to achieve the cleaning of impurities.

[0051] And the high temperature gas softens some impurities, making them easier to clean.

[0052] A plurality of groups of first rotating tubes 5 and second rotating tubes 6 are provided, so that the steel passes through a plurality of horizontally distributed heating zones, which can straighten the steel while preheating it, thereby improving the bending efficiency.

[0053] Since the guide cylinder 11 is a circular structure, the ventilation slot 17 is an arc shape. Fig. 9 In the middle state, even if the middle section of the ventilation slot 17 may be blocked by the steel, both ends thereof are still in an open state; and during the steel conveying process, preheating treatment is achieved at all positions.

[0054] By providing the first rotating tube 5, the second rotating tube 6, the guide cylinder 11 and the ventilation slot 17 and other structures, the effects of preheating, impurity cleaning and straightening are achieved at the same time, the steel is prevented from breaking, the work efficiency is improved, and the manufacturing quality of the composite tension insulator is guaranteed.

[0055] In addition, the plurality of first rotating tubes 5 are distributed in a horizontal straight line and move synchronously up and down, which is suitable for steels of various sizes, thereby improving the applicability of the equipment.

[0056] Moreover, after the guide tube 11 structure is heated up, the heat can also be transferred to the steel.

[0057] A slide groove 13 is provided between the two ventilation grooves 17. The slide groove 13 is provided on the inner wall of the annular groove 14. The annular groove 14 is connected with the guide cylinder 11 through the slide groove 13. A plurality of ventilation components are provided, and the plurality of ventilation components are evenly distributed around the annular groove 14, so that the slide grooves 13 are also multiple, and the plurality of slide grooves 13 are distributed one-to-one with the plurality of ventilation components.

[0058] In order to prevent all the ventilation slots 17 on the guide cylinder 11 from opening at the same time, so that the wind force is dispersed and the efficiency of air supply and suction is reduced, a sliding column 12 is provided inside the slide groove 13 for sliding. One end of the sliding column 12 located inside the annular groove 14 is fixedly connected to an arc block 15 that slides by extrusion of steel. The arc block 15 is arc-shaped. The end of the sliding column 12 away from the arc block 15 is fixedly connected to an arc plate 16, and the arc plate 16 is sealed with the ventilation slot 17.

[0059] In order to realize the reset of the arc block 15 and the arc plate 16, a circular groove 18 is provided on the inner wall of the slide groove 13, and the circular groove 18 surrounds the outer side of the slide column 12. A slide plate 19 is provided inside the circular groove 18, and the slide plate 19 is fixedly connected to the slide column 12. A spring 20 is sleeved on the outside of the slide column 12, one end of the spring 20 is fixedly connected to the slide plate 19, and the other end of the spring 20 is fixedly connected to the inner wall of the circular groove 18. The elastic supporting force of the spring 20 is appropriate, and does not affect the steel in the conveying process, and drives the upper and lower guide cylinders 11 to rotate.

[0060] Specifically, the steel is heated in multiple zones in sequence. At this time, the steel is located between the upper and lower annular grooves 14. The arc block 15 squeezes the sliding column 12 to move toward the axial direction of the corresponding guide cylinder 11, and the sliding column 12 drives the arc plate 16 to move synchronously, and the ventilation slot 17 is opened.

[0061] During the conveying process, the steel drives the upper and lower guide cylinders 11 to rotate. When the arc block 15 contacts the steel, the corresponding ventilation slot 17 opens, and high-temperature gas is ejected from the ventilation slot 17. When the arc block 15 is offset from the steel, the restoring elastic force of the spring 20 drives the arc plate 16 to reset through the slide plate 19, separating the corresponding ventilation slot 17 from the inner cavity of the guide cylinder 11, and the ventilation slot 17 remains closed, ensuring that the high-temperature gas flow rate blowing to the steel position is large, making the heat transfer speed faster, improving the utilization efficiency of the high-temperature gas, and avoiding the waste of heat energy.

[0062] By arranging structures such as the sliding column 12, the arc block 15 and the arc plate 16, under the extrusion and matching effect of the steel, the high-temperature gas flow rate blown to the steel position is ensured to be large, so that the heat transfer speed is fast, the utilization efficiency of the high-temperature gas is improved, and the waste of heat energy is avoided.

[0063] And in the specific use process, a conveying device is provided to convey the steel. The conveying device includes structures such as clamps, etc., which often clamp and convey the steel. The conveying device is an existing common technology and will not be described in detail here.

[0064] The upper surface of the chassis 1 is fixedly connected with a vertical plate 2. The upper half of the vertical plate 2 is provided with a plurality of evenly distributed sliding channels 3. A sliding box 4 is slidably provided inside the sliding channel 3. The sliding box 4 is H-shaped. A suction chamber 7 and an air supply chamber 8 are provided inside the vertical plate 2. A through slot 30 is provided on the sliding box 4. The sliding box 4 is connected to the suction chamber 7 through the through slot 30. The first rotating tube 5 is rotatably connected to the corresponding sliding box 4. The first rotating tube 5 is provided with a first square slot 9. The first rotating tube 5 is connected to the sliding box 4 through the first square slot 9. Even in the rotating state, the first rotating tube 5 can always be connected to the suction chamber 7. An adjusting member 21 is provided above the sliding box 4. The adjusting member 21 is threadedly connected to the vertical plate 2. The adjusting member 21 cooperates with the sliding box 4. The adjusting member 21 includes a threaded rod and a turning handle. Specifically, the adjusting member 21 is rotated to drive the slide box 4 to slide inside the slide channel 3, so that the first rotating tube 5 drives the guide cylinder 11 at the upper position to move synchronously, and the distance between the upper and lower guide cylinders 11 is adjusted according to the size of the steel.

[0065] The second rotating tube 6 is rotatably connected to the vertical plate 2, and a second square groove 10 is provided on the second rotating tube 6. The second rotating tube 6 is connected to the air supply chamber 8 through the second square groove 10. Even in the rotating state, the second rotating tube 6 can always be connected to the air supply chamber 8. A sealing ring and other structures (not shown in the figure) are provided at the connection between the first rotating tube 5 and the sliding box 4 and at the connection between the second rotating tube 6 and the air supply chamber 8.

[0066] The chassis 1 is provided with a wind power component that cooperates with the suction chamber 7 and the air supply chamber 8. The wind power component includes a fan 31, a first air duct 32, a processing box 33 and a second air duct 34. The fan 31 and the processing box 33 are both fixedly connected to the upper surface of the chassis 1. The processing box 33 is connected to the air inlet end of the fan 31. The processing box 33 is provided with a filtering device and a heating device (not shown in the figure) inside the processing box 33. The filtering device includes a filter screen and other structures, which can filter impurities; the heating device includes an electric heating wire and other structures, which can quickly heat the gas passing through the processing box 33. The filtering device and the heating device are both existing common technologies and are not described here. One end of the first air duct 32 is connected to the air outlet end of the fan 31, and the other end of the first air duct 32 is connected to the air supply chamber 8. One end of the second air duct 34 is connected to the processing box 33, and the other end of the second air duct 34 is connected to the suction chamber 7.

[0067] Specifically, the air outlet end of the fan 31 transports the high-temperature gas from the first air duct 32 to the interior of the air supply chamber 8, and enters the second rotating tube 6 from the second square slot 10, and then is sprayed toward the steel from the guide cylinder 11 and the ventilation slot 17 at the lower position to preheat the steel; at the same time, the air inlet end of the fan 31 sucks the ejected gas through the second air duct 34, the suction chamber 7, the first square slot 9, the first rotating tube 5, the guide cylinder 11 at the upper position and the ventilation slot 17.

[0068] A single fan 31 is provided, and with the cooperation of structures such as a processing box 33, air supply and suction are performed simultaneously, thereby reducing energy consumption and equipment use costs.

[0069] Taking into account that dust, iron filings and other impurities adhere to the outside of the steel, it is easy to slip during bending and affect the heating efficiency. In order to clean the impurities, a first support plate 22 is fixedly connected to one end of the vertical plate 2, and a cleaning cylinder 23 for the steel to pass through is fixedly connected to the first support plate 22, and a wire brush 24 is fixedly arranged inside the cleaning cylinder 23.

[0070] The other end of the vertical plate 2 is fixedly connected to a second support plate 25, and the second support plate 25 is fixedly connected to an insulation tube 26 through which the steel passes. The insulation tube 26 can be made of but not limited to insulation cotton material, and has an insulation effect to insulate the steel part that is preheated and about to enter the bending station.

[0071] During operation, the steel is sequentially conveyed through the cleaning cylinder 23, multiple heating zones and the heat preservation cylinder 26. When the steel is slid and conveyed inside the cleaning cylinder 23, the wire brush 24 is attached to the outside to scrape off dust, iron filings and other impurities on the outside to avoid slipping during bending and prevent heating from being affected.

[0072] When the scraped impurities adhere to the steel and are transported with it, after entering the heating zone, the high-temperature gas is sprayed toward the steel from the guide cylinder 11 and the ventilation groove 17 at the lower position to blow away the impurities; at the same time, the impurities are sucked away by the guide cylinder 11 and the ventilation groove 17 at the upper position, and the blowing and suction are carried out simultaneously.

[0073] The preheated steel passes through the interior of the heat preservation tube 26 to achieve the heat preservation effect, and then enters the bending work, and is made into a U-shaped ring under the cooperation of the cutting device 29 and the bending device 28.

[0074] By arranging structures such as the cleaning cylinder 23, the guide cylinder 11, the heat-insulating cylinder 26 and the bending device 28, continuous processing is achieved and the manufacturing efficiency is improved.

[0075] Working principle: Rotate the adjusting member 21 to drive the slide box 4 to slide inside the slide channel 3, so that the first rotating tube 5 drives the guide cylinder 11 in the upper position to move synchronously, and adjust the distance between the upper and lower guide cylinders 11 according to the size of the steel; the steel passes through the cleaning cylinder 23, multiple heating zones and the insulation cylinder 26 in sequence and is transported. At this time, the steel is located between the upper and lower annular grooves 14, and the sliding column 12 is squeezed by the arc block 15 to move toward the axial direction of the corresponding guide cylinder 11, and the arc plate 16 is driven to move synchronously through the sliding column 12, and the ventilation slot 17 is opened.

[0076] Start the fan 31, and the air outlet of the fan 31 transports the high-temperature gas from the first air duct 32 to the inside of the air supply chamber 8, and enters the second rotating tube 6 from the second square groove 10, and then is sprayed to the steel from the guide cylinder 11 and the ventilation groove 17 at the lower position, so as to preheat the steel to facilitate bending and deformation, reduce the internal stress generated by the steel during bending, and prevent quality problems such as deformation or cracks of the steel due to bending; at the same time, the air inlet end of the fan 31 sucks the ejected gas through the second air duct 34, the suction chamber 7, the first square groove 9, the first rotating tube 5, the guide cylinder 11 at the upper position and the ventilation groove 17, so that the high-temperature gas flows at the steel, realizes the circulation of the high-temperature gas, and avoids heat waste.

[0077] During the conveying process, the steel drives the upper and lower guide cylinders 11 to rotate. When the arc block 15 contacts the steel, the corresponding ventilation slot 17 opens, and high-temperature gas is ejected from the ventilation slot 17. When the arc block 15 is offset from the steel, the restoring elastic force of the spring 20 drives the arc plate 16 to reset through the slide plate 19, separating the corresponding ventilation slot 17 from the inner cavity of the guide cylinder 11, and the ventilation slot 17 remains closed, ensuring that the high-temperature gas flow rate blowing to the steel position is large, making the heat transfer speed faster, improving the utilization efficiency of the high-temperature gas, and avoiding the waste of heat energy.

[0078] When the steel is slid and transported inside the cleaning cylinder 23, the wire brush 24 is attached to the outside thereof to scrape off dust, iron filings and other impurities on the outside thereof to avoid slipping during bending and to prevent influence on heating.

[0079] When the scraped impurities adhere to the steel and are transported with it, after entering the heating zone, the high-temperature gas is sprayed toward the steel from the guide cylinder 11 and the ventilation slot 17 at the lower position to blow away the impurities, and the high-temperature gas softens some of the impurities, making them easier to clean. At the same time, the impurities are sucked away by the guide cylinder 11 and the ventilation slot 17 at the upper position, and the blowing and suction are carried out simultaneously to achieve the cleaning of the impurities.

[0080] The impurities are filtered and processed inside the processing box 33 .

[0081] At the same time, since a plurality of groups of first rotating tubes 5 and second rotating tubes 6 are arranged on the vertical plate 2, the steel passes through a plurality of horizontally distributed heating zones, which can straighten the steel while preheating, thereby improving the bending efficiency.

[0082] The preheated steel passes through the interior of the heat preservation tube 26 to achieve the heat preservation effect, and then enters the bending work, and is made into a U-shaped ring under the cooperation of the cutting device 29 and the bending device 28.
