DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying drawings to clarify the technical solutions in the embodiments of the present invention; although it is clear that the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The present invention provides Figures 1 to 9A metal wire product straightening device shown can be used to straighten metal wires including aluminum, tungsten, copper, magnesium, titanium, etc., and includes an operating table 1. A wire guide drum 3 is provided above the operating table 1. Both ends of the wire guide drum 3 are fixedly connected to a bracket 30, and the bracket 30 is fixedly connected to the operating table 1. A metal wire product body 13 is placed in the wire guide drum 3. A traction mechanism 2 for straightening and pulling the metal wire product body 13 is provided on the top of the operating table 1. The traction mechanism 2 includes two upper and lower distribution rollers and a motor. The metal wire product body 13 is clamped between the two upper and lower distribution rollers, and with the cooperation of the motor, the metal wire product body 13 is pulled and continuously straightened. It can be adjusted to other structures according to specific usage conditions. The traction mechanism 2 is an existing common technology and will not be described in detail here.

[0035] In addition, a reel-shaped metal wire product body 13 (not shown in the figure) is placed on the top of the operating table 1 and at one end away from the traction mechanism 2, so that the reel-shaped metal wire product body 13 can be straightened.

[0036] Considering that the reel-shaped metal wire product body 13 will form a large internal stress due to long-term curling, the prior art mostly adopts multiple rows of straightening wheels for guiding and straightening. After a short period of horizontal and vertical rolling, although it appears to be a relatively straight state, it cannot fully eliminate the internal stress caused by the curling of the metal wire product body 13. After straightening, the metal wire product body 13 will gradually bend. In order to improve the efficiency of straightening the metal wire product body 13, a U-shaped seat 4 is fixedly connected to the inner wall of the wire guide cylinder 3. The U-shaped seat 4 is provided in multiple rows. Multiple U-shaped seats 4 are staggered vertically along the axial length of the wire guide barrel 3. A sheave 5 is rotatably mounted on one end of the U-shaped seat 4, close to the axis of the wire guide barrel 3. Sliding channels 31 are provided on both sides of the U-shaped seat 4. Slide plates 15 are slidably connected to the interior of the sliding channels 31. A round rod 16 is fixedly connected between the two slide plates 15. The sheave 5 is rotatably connected to the round rod 16. An elastic telescopic rod 17 is provided inside the sliding channel 31. One end of the elastic telescopic rod 17 is fixedly connected to the slide plate 15, and the other end of the elastic telescopic rod 17 is fixedly connected to the inner wall of the sliding channel 31. To improve the sliding stability of the slide plate 15, a chute 18 is provided on the inner wall of the sliding channel 31. A slider 19 is slidably connected to the interior of the chute 18. The slider 19 is fixedly connected to the slide plate 15. The metal wire-like product body 13 is wound around the multiple sheaves 5 in an S-shape.

[0037] Specifically, the metal wire product body 13 is passed through the inside of the wire guide tube 3 and is wound in an S shape on multiple groove wheels 5 for transportation. It can be folded in the positive and negative directions multiple times, thereby smoothing and eliminating the internal stress of the curling, thereby achieving the internal stress elimination and auxiliary straightening of the metal wire product body 13.

[0038] At the same time, during the transportation of the metal wire-like product body 13, the elastic telescopic rod 17 will be squeezed and contracted through the groove wheel 5, the round rod 16, the slide plate 15, etc., and the reset elastic force of the elastic telescopic rod 17 can react to the metal wire-like product body 13 through the groove wheel 5. With the cooperation of multiple sets of groove wheels 5 and elastic telescopic rods 17, a tensioning effect is achieved, and there are more force points, thereby improving the quality of straightening.

[0039] In addition, during the transportation process, the metal wire-like product body 13 is attached to the outer ring of the groove wheel 5, causing the groove wheel 5 to rotate, which can reduce friction and prevent the metal wire-like product body 13 from being worn.

[0040] By providing multiple sets of U-shaped seats 4, sheaves 5 and other structures, the effects of eliminating internal stress, assisting in straightening, tensioning and reducing friction can be achieved simultaneously, thereby improving the straightening quality of the metal wire product body 13.

[0041] To preheat the metal wire product body 13, a through slot 7 for conveying high-temperature gas is provided at the end of the U-shaped seat 4 away from the sheave 5. A rotating rod 8 is fixedly connected to the end of the through slot 7 near the sheave 5. A rotating block 9 is rotatably connected to the rotating rod 8, and the rotating block 9 fits against the inner wall of the through slot 7. An air outlet slot 12 is provided through the rotating block 9. Multiple air outlet slots 12 are provided, and each of the multiple air outlet slots 12 can be set at different angles to expand the area of ​​action of the high-temperature gas. The high-temperature gas is ejected from the air outlet slots 12 to form a high-temperature airflow, which is directed toward the metal wire product body 13, achieving the effect of preheating the metal wire product body 13, further eliminating stress within the metal wire product body 13, and further improving the quality of the straightening of the metal wire product body 13.

[0042] Since the air outlet slot 12 is close to the metal wire product body 13, the effect of the high-temperature gas can be enhanced.

[0043] Since the metal wire-like product body 13 is wound on multiple sheaves 5 in an S shape, among two adjacent sheaves 5, one sheave 5 heats the lower half of the metal wire-like product body 13, while the other sheave 5 heats the upper half of the metal wire-like product body 13, thereby maintaining heating uniformity; and multiple sheaves 5 cooperate with the wire guide tube 3 to extend the heating mileage.

[0044] Reference Figure 6 As shown, the inner wall of the through slot 7 away from the rotating rod 8 is arc-shaped. When the rotating block 9 rotates toward the inside of the through slot 7 with the rotating rod 8 as the axis, the end of the rotating block 9 away from the rotating rod 8 will slide on the inner wall of the through slot 7.

[0045] In order to achieve the reset of the rotating block 9, circular holes 10 are opened on both sides of the rotating block 9, and a torsion spring 11 is arranged inside the circular hole 10. The torsion spring 11 is sleeved on the rotating rod 8. One end of the torsion spring 11 is fixed on the inner wall of the circular hole 10, and the other end of the torsion spring 11 is fixed on the inner wall of the through groove 7.

[0046] A plurality of first magnets 6 are fixedly embedded in the outer ring of the sheave 5, and are evenly distributed around the outer ring. A second magnet 14 is fixedly embedded in the side of the rotating block 9 closest to the sheave 5, and the first magnets 6 and second magnets 14 repel each other. Both the first magnet 6 and the second magnet 14 are high-temperature resistant magnets, capable of normal operation in a preheated environment, and can be adjusted according to specific usage conditions.

[0047] During operation, during the rotation of the sheave 5, when one of the first magnets 6 and the second magnet 14 are distributed correspondingly up and down, under the action of the repulsive force, the rotating block 9 rotates inside the through slot 7 with the rotating rod 8 as the axis, causing the angle of the air outlet slot 12 to change, and the high-temperature airflow to swing, thereby expanding the range of action; the sheave 5 continues to rotate, and when the first magnet 6 and the second magnet 14 are staggered, the rotating block 9 is reset under the action of the restoring elastic force of the torsion spring 11, and the high-temperature airflow swings again.

[0048] As the sheave 5 continues to rotate, the multiple first magnets 6 cooperate with the second magnet 14 in turn, so that the rotating block 9 rotates and resets periodically, and the high-temperature airflow continues to swing, thereby expanding the range of wind action, ensuring heating uniformity, improving the preheating effect of the metal wire product body 13 before straightening, and ensuring the straightening quality; it can also prevent the high-temperature airflow from always blowing to the same position of the sheave 5, reducing the wind wear on the sheave 5.

[0049] When the rotating block 9 rotates in the through slot 7 with the rotating rod 8 as the axis, the volume inside the through slot 7 is compressed, which can speed up the ejection of high-temperature gas from the air outlet slot 12 and improve the heating efficiency.

[0050] In order to transport high-temperature gas to the interior of the through groove 7, an inner cavity 20 is opened inside the wall of the wire guide tube 3. The through groove 7 is connected to the inner cavity 20, and a second solenoid valve 29 is fixedly installed at one end of the through groove 7 near the inner cavity 20. The operating table 1 is provided with a wind power mechanism that cooperates with the inner cavity 20. The wind power mechanism includes an air pump 25, a heating box 26, a first air duct 27, and a second air duct 28. The air pump 25 and the heating box 26 are both fixedly connected to the operating table 1. The interior of the heating box 26 is provided with a heating device. The heating device includes an electric heating plate and other structures. It can quickly heat the gas passing through the interior of the heating box 26 to form a high-temperature gas suitable for preheating the metal wire product body 13. A filtering device can also be provided to cooperate with the air pump 25. The filtering device includes a filter screen and other structures to process dust and other impurities. The heating device and the filtering device are both common existing technologies and will not be described in detail here. The air outlet end of the air pump 25 is connected to the heating box 26, one end of the first air duct 27 is connected to the heating box 26, the other end of the first air duct 27 is connected to the inner cavity 20, one end of the second air duct 28 is connected to the air inlet end of the air pump 25, and the other end of the second air duct 28 passes through the wall of the wire guide tube 3 and extends to the interior of the wire guide tube 3.

[0051] During operation, the second solenoid valve 29 in all positions is opened, and the air pump 25, in cooperation with the heating box 26, delivers high-temperature gas to the interior of the inner cavity 20. The high-temperature gas enters the interior of the through groove 7 and is ejected from the air outlet groove 12 to form a high-temperature airflow and head towards the metal wire product body 13.

[0052] At the same time, the air pump 25 sucks the used gas inside the wire guide tube 3 through the second air duct 28, and transports it back to the inside of the wire guide tube 3 after reheating, thereby realizing high-temperature gas circulation; and since the sucked gas has a certain temperature, it can be quickly heated and utilized, thereby achieving the purpose of reducing energy consumption.

[0053] By setting up structures such as the wire guide tube 3 and the wind mechanism, high-temperature gas circulation is achieved inside the wire guide tube 3, thereby reducing energy consumption. At the same time, the metal wire product body 13 is prevented from being affected by external impurities such as dust during preheating, and after the high-temperature gas enters the inner cavity 20, it can achieve a heat preservation effect.

[0054] During specific use, structures such as heat-insulating cotton can be arranged outside the wire guide cylinder 3 .

[0055] Both ends of the wire guide barrel 3 are provided with circular grooves 21 through which the metal filamentary body 13 passes. An elastic airbag 22 is fixedly connected to the interior of the circular groove 21. The elastic airbag 22 is made of wear-resistant rubber and can automatically recover its deformation. The elastic airbag 22 surrounds the outside of the metal filamentary body 13. The inner wall of the circular groove 21 defines a gas channel 23, which connects the elastic airbag 22 to the inner cavity 20. A first solenoid valve 24 is fixedly installed inside the gas channel 23.

[0056] During operation, the metal wire product body 13 is passed through the circular groove 21 at one end away from the traction mechanism 2 into the interior of the wire guide cylinder 3, and the elastic air bag 22 inside the circular groove 21 surrounds the outside of the metal wire product body 13, and then the metal wire product body 13 is wound on the multiple groove wheels 5 in an S shape (refer to Figure 5 As shown), it then passes through the circular groove 21 near one end of the traction mechanism 2, and the elastic airbag 22 inside the circular groove 21 also surrounds the outside of the metal wire product body 13, and finally the end of the metal wire product body 13 is docked on the traction mechanism 2 to complete the loading operation, and the traction mechanism 2 is subsequently used for traction and pulling.

[0057] Open the first solenoid valve 24, close the second solenoid valve 29 in all positions, start the air pump 25, and transport gas to the inner cavity 20 through the first air duct 27. The gas entering the inner cavity 20 enters the elastic airbag 22 through the gas channel 23, so that the elastic airbags 22 at both ends of the wire guide tube 3 expand and become larger at the same time, and the elastic airbags 22 are wrapped around the outside of the metal wire product body 13. Then close the first solenoid valve 24, so that the elastic airbag 22 remains in an expanded state, but this expanded state will not completely lock the metal wire product body 13, and will not affect the traction and pulling of the metal wire product body 13.

[0058] By providing the elastic airbag 22 , the metal wire product body 13 is tensioned, and the circular groove 21 is blocked to prevent heat loss inside the wire guide barrel 3 and reduce wear of the metal wire product body 13 at the circular groove 21 .

[0059] Working principle: The metal wire product body 13 is passed through the circular groove 21 at one end away from the traction mechanism 2 into the interior of the wire guide cylinder 3, and the elastic air bag 22 inside the circular groove 21 surrounds the outside of the metal wire product body 13, and then the metal wire product body 13 is wound on multiple groove wheels 5 in an S shape (refer to Figure 5 As shown), it then passes through the circular groove 21 near one end of the traction mechanism 2, and the elastic airbag 22 inside the circular groove 21 also surrounds the outside of the metal wire product body 13, and finally the end of the metal wire product body 13 is docked on the traction mechanism 2 to complete the loading operation, and the traction mechanism 2 is subsequently used for traction and pulling.

[0060] Open the first solenoid valve 24, close the second solenoid valve 29 in all positions, start the air pump 25, and transport gas to the inner cavity 20 through the first air duct 27. The gas entering the inner cavity 20 enters the elastic airbag 22 through the gas channel 23, so that the elastic airbags 22 at both ends of the wire guide tube 3 expand and become larger at the same time, and the elastic airbags 22 are wrapped around the outside of the metal wire product body 13. Then close the first solenoid valve 24 to keep the elastic airbag 22 in an expanded state, but this expanded state will not completely lock the metal wire product body 13, and will not affect the traction and pulling of the metal wire product body 13, thereby achieving the effect of tensioning the metal wire product body 13 and blocking the circular groove 21 to prevent heat loss inside the wire guide tube 3.

[0061] Then open the second solenoid valve 29 in all positions, and the air pump 25, in cooperation with the heating box 26, transports high-temperature gas into the inner cavity 20. The high-temperature gas enters the interior of the through groove 7 and is ejected from the air outlet groove 12 to form a high-temperature airflow, and is directed toward the metal wire product body 13, thereby achieving the effect of preheating the metal wire product body 13.

[0062] During the transportation process, the metal wire-like product body 13 is attached to the outer ring of the groove wheel 5, causing the groove wheel 5 to rotate, which can reduce friction and prevent the metal wire-like product body 13 from being worn.

[0063] The wire-like product body 13 is wound in an S-shape on multiple sheaves 5 for transport, and can be folded multiple times to smooth and eliminate the internal stress of the curling, thereby eliminating the internal stress of the wire-like product body 13 and assisting in straightening. The slide plate 15, round rod 16, and elastic telescopic rod 17 cooperate to achieve a tensioning effect.

[0064] During the rotation of the sheave 5, when one of the first magnets 6 and the second magnet 14 are aligned vertically, the repulsive force causes the rotating block 9 to rotate with the rotating rod 8 as the axis toward the interior of the through slot 7, causing the air outlet slot 12 to change angle and the high-temperature airflow to oscillate. The sheave 5 continues to rotate, and when the first magnet 6 and the second magnet 14 become dislocated, the rotating block 9 is reset by the reset force of the torsion spring 11, causing the high-temperature airflow to oscillate again. As the sheave 5 continues to rotate, the multiple first magnets 6 alternately cooperate with the second magnet 14, causing the rotating block 9 to rotate and reset periodically, and the high-temperature airflow to continue to oscillate. This expands the wind's range of action, improves the preheating effect of the metal wire product body 13 before straightening, and ensures the quality of straightening. It also prevents the high-temperature airflow from always blowing toward the same position on the sheave 5, reducing wind wear on the sheave 5.

[0065] In addition, when the rotating block 9 rotates inside the through slot 7 with the rotating rod 8 as the axis, the volume inside the through slot 7 is compressed, which can speed up the speed of high-temperature gas being ejected from the air outlet slot 12 and improve the heating efficiency.

[0066] Since the metal wire-like product body 13 is wound on multiple sheaves 5 in an S shape, among two adjacent sheaves 5, one sheave 5 heats the lower half of the metal wire-like product body 13, while the other sheave 5 heats the upper half of the metal wire-like product body 13, thereby maintaining heating uniformity; and multiple sheaves 5 cooperate with the wire guide tube 3 to extend the heating mileage.
