Description
Technical Field
[0001] The present invention relates to the technical field of torsion guides, and particularly relates to an auxiliary device for adjusting the torsion angle of a torsion guide in a bar production line. Background Art
[0002] A torsion guide is a special device used to adjust the torsion angle of rolled materials in a bar production line, and is mainly applied to the scenario of continuous multi-pass rolling in a finishing mill. During the rolling process, when the steel material after flat rolling needs to be twisted by a certain angle to enter the next stand, the torsion angle needs to be adjusted by the torsion guide to ensure that the steel material enters the next stand.
[0003] Currently, the common method for adjusting the torsion angle of a torsion guide is to use a sample bar for adjustment. The sample bar is a standard measuring tool of a specific specification, usually made of metal, and has the same shape as the rolled steel material. When adjusting the torsion angle, the sample bar is inserted between the upper and lower wheels of the torsion guide, and the worm of the torsion guide is adjusted to make the sample bar fit perfectly with the upper and lower wheels of the torsion guide. Then, the torsion angle of each specification of the torsion guide is controlled according to the experience of the adjusting worker.
[0004] However, manual experience has a great influence on the adjustment of the torsion angle, and it is easy to occur that the steel material cannot enter the next stand due to a large deviation in the torsion angle after twisting, resulting in a steel stockpiling accident. Summary of the Invention
[0005] The purpose of the present invention is to provide an auxiliary device for adjusting the torsion angle of a torsion guide in a bar production line, so as to solve the problem that it is easy to occur that the steel material cannot enter the next stand due to manual experience in adjusting the torsion angle, resulting in a steel stockpiling accident.
[0006] To achieve the above object, the basic solution provided by the present invention is: an auxiliary device for adjusting the torsion angle of a torsion guide in a bar production line, including a base, an angle ruler, a measuring plate and a bolt. A fixed seat is provided on the base. Through holes are opened on the angle ruler and the measuring plate. The bolt movably penetrates through the through holes and is threadedly connected with the fixed seat. A concave body for supporting the angle ruler and the measuring plate is provided on the base. A locking structure for clamping the torsion guide is provided on the base.
[0007] The working principle of the present invention is as follows: When adjusting the torsion angle of the torsion guide (taking a straight threaded steel bar with a nominal diameter of 12 mm as an example), first, the torsion guide is firmly fixed on the base through the locking structure, and then the adjustment of the torsion angle of the torsion guide is started. Loosen the bolts between the angle ruler and the measuring plate and the fixed seat, then insert the sample bar between the upper and lower wheels of the torsion guide, adjust the opening degree of the upper and lower wheels of the torsion guide to ensure that the center of the lower wheel of the torsion guide is horizontal with the upper wheel of the torsion guide. Since the torsion angle of the straight threaded steel bar with a nominal diameter of 12 mm is 22°, the angle ruler and the measuring plate are set to a torsion angle of 22°, and then tighten the bolts. Then, by adjusting the worm of the torsion guide, make the inclined plane above the sample bar parallel to the lower part of the angle ruler, thus completing the adjustment of the torsion angle of the torsion guide.
[0008] The beneficial effect of the present invention is that by using the angle ruler and the measuring plate in cooperation with the sample bar for angle measurement and adjustment, compared with the traditional adjustment relying on manual experience, it can effectively avoid angle deviation caused by experience differences and improve the adjustment quality.
[0009] Solution two, which is the optimization of the basic solution. The locking structure includes two first sliders. Each first slider is connected with a first screw rod through a bearing. The base is symmetrically provided with first bearing seats. Each first screw rod movably penetrates through the first bearing seat. Each first screw rod is threadedly connected with a first nut. Each first nut is fixedly connected with the inner side wall of the inner ring of the first bearing seat. The locking structure composed of the first slider, the first screw rod, the first bearing seat and the first nut can clamp and fix the position of the torsion guide, avoiding the shaking of the torsion guide during the adjustment process and affecting the measurement accuracy.
[0010] Solution three, which is the optimization of solution two. On one side of each first slider close to the torsion guide, there is a chute. Two second sliders are slidably connected to the chute. On both sides of the first slider close to the chute, there are support plates connected by screws. Each support plate is provided with two springs. Each spring is fixedly connected with the second slider. The chute on the first slider, the second slider, the support plate and the spring constitute an elastic clamping structure. When clamping the torsion guide, it can ensure the lateral offset of the torsion guide under the action of the spring.
[0011] Solution four, which is the optimization of solution three. On both sides of the top of the base, there are grooves. At the bottom of each support plate, there is a third slider for slidably connecting with the groove. The sliding connection between the third slider and the groove can move smoothly along a fixed direction, avoiding the offset of the first slider during the sliding process.
[0012] Solution Five, which is the preference of the basic solution. A fixed shaft is provided at the bottom of the base. A first bearing is provided on the fixed shaft, and the fixed shaft is fixedly connected to the inner ring of the first bearing. A support body is provided at the bottom of the first bearing, and a base is provided at the bottom of the support body. A limiting structure for restricting the movement of the moving base is provided on the base. Through the fixed shaft, the first bearing, the support body and the base, the base can rotate flexibly relative to the base, facilitating workers to adjust the torsion guard at different positions.
[0013] Solution Six, which is the preference of Solution Five. The limiting structure includes two worm gears. Second bearing seats are symmetrically provided on the base, and the two worm gears are connected to the second bearing seats. A rotating shaft is provided between the two worm gears, and the rotating shaft movably penetrates through the support body. Column-shaped holes are symmetrically formed on the base, and a sleeve is fixedly connected in each column-shaped hole. The inner wall of each sleeve is threaded, and a second screw rod is threadedly connected in each sleeve. One ends of the two second screw rods extending outside the sleeves are respectively threadedly connected with second nuts. A second bearing is provided at the open end of each sleeve, and each second screw rod movably penetrates through the second bearing. The second nut is fixedly connected to the side wall of the inner ring of the second bearing. A worm wheel is fixedly connected to the two second nuts, and the adjacent two worm wheels are meshed with the worm gear. The second nut abuts against the top of the sleeve. The limiting structure composed of the worm gear, the worm wheel, the second screw rod and the second nut drives the second screw rod to move up and down through the transmission of the worm gear and the worm wheel to limit the base. At the same time, when the two screw rods move up and limit at the same time, the base can be in a horizontal state, thus avoiding accuracy deviation when the torsion angle of the torsion guard on the base is twisted.
[0014] Solution Seven, which is the preference of Solution Six. Arc-shaped plates are respectively connected to the tops of the two second screw rods through bearings, and two limiting rods are provided on the base, and the limiting rods movably penetrate through the arc-shaped plates. By providing the arc-shaped plates, the contact area between the second screw rod and the bottom of the base is increased, and the rotation of the second screw rod is restricted by the limiting rods so that it can move up and down.
[0015] Solution Eight, which is the preference of the basic solution. A spirit level is provided on the base. Whether the base is in a horizontal state can be seen through the setting of the spirit level.
[0016] Solution Nine, which is the preference of Solution Two or Solution Six. A first crank is respectively provided on each first nut and the worm gear, and a second crank is respectively provided on each second nut and the worm gear. The first crank on the first nut and the second crank on the worm gear facilitate the operator to rotate the first nut and the worm gear labor-saving and conveniently. Description of the Drawings

[0019] Such as Figures 1 to 6As shown in the figure: An auxiliary device for adjusting the torsion angle of the torsion guide in a bar production line, including a base 1, an angle ruler 2, a measuring plate 3 and a bolt 5.

The surface of the measuring plate 3 abutted against the concave body 6 and the center position of the bolt 5 of the fixed seat 4 are at the same horizontal level, which can prevent the measuring plate 3 from tilting relative to the base 1 and causing errors in the torsion angle. A locking structure for clamping the torsion guide is provided on the base 1. The torsion guides are all of the same model. The locking structure includes two first sliders 7. A first screw 8 is connected to each first slider 7 by a bearing. First bearing seats 9 are symmetrically provided on the base 1. Each first screw 8 movably passes through the first bearing seat 9.

When clamping is required, the two first sliders 7 clamp both sides of the torsion guide. Grooves 11 are provided on both sides of the top of the base 1. A third slider 12 for slidably connecting to the groove 11 is provided at the bottom of each support plate 16.
[0020] A fixed shaft 18 is fixedly connected to the bottom of the base 1. A first bearing 19 is fixedly connected to the fixed shaft 18. The fixed shaft 18 is fixedly connected to the inner ring of the first bearing 19. A support 20 is fixedly connected to the bottom of the first bearing 19. A base 21 is fixedly connected to the bottom of the support 20. A spirit level 13 is provided on the base 1. A limiting structure for restricting the movement of the base 1 is provided on the base 21. The limiting structure includes two worm gears 22. Two second bearing seats 23 are provided on the base 21. The two worm gears 22 are fixedly connected to the inner rings of the second bearing seats 23. A rotating shaft 25 is provided between the two worm gears 22. The rotating shaft 25 movably penetrates through the support 20. Cylindrical holes are symmetrically formed in the base 21. A sleeve 24 is fixedly connected to each cylindrical hole. The inner wall of each sleeve 24 is threaded. A second screw 26 is threadedly connected to each sleeve 24. The tops of the two second screws 26 are respectively connected to an arc-shaped plate 29 by bearings. Two limiting rods 32 are provided on the base 21. The limiting rod 34 movably penetrates through the arc-shaped plate 29. The ends of the two second screws 26 extending outside the sleeve 24 are respectively threadedly connected to a second nut 27. A bearing two 35 is provided at the open end of each sleeve 24. Each second screw 26 movably penetrates through the bearing two 35. The second nut 27 is fixedly connected to the inner ring side wall of the bearing two 35. A worm wheel 28 is fixedly connected to the two second nuts 27. The adjacent two worm wheels 28 are meshed with the worm gear 22. The second nut 27 abuts against the top of the sleeve 24. A second crank 31 is fixedly connected to the worm gear 22.
[0021] The implementation manner of this embodiment is as follows: When the torsion guide 32 needs to be installed on this device, first place the torsion guide 32 on the base 1, and then rotate the first crank 30 on the first nut 10 (at this time, the first nut 10 abuts against one side surface of the first bearing seat 9). The rotation of the first nut 10 drives the first screw 8 to rotate in the threaded hole of the first bearing seat 9, so that the two first screws 8 move relatively closer or farther away. The two first screws 8 drive the third slider 12 to be slidably connected to the groove 11 on the base 1. Since one side of the two second sliders 15 is curved, when the two second sliders 15 on the first slider 7 come into contact with the torsion guide 32, the two second sliders 15 slide to both sides, and at the same time, the spring 17 is compressed and squeezed to both sides. When the surfaces of the two first sliders 7 abut and clamp the torsion guide 32, the rotation of the first crank 30 of the first nut 10 can be stopped. The second slider 15 abuts against the torsion guide 32 under the action of the spring 17, and further firmly fixes the torsion guide 32. When it is necessary to adjust the torsion angle of the torsion guide 32 (taking the straight threaded steel bar with a nominal diameter of 12 mm as an example), first, rotate the second crank 31 on the worm 22. The worm 22 drives another worm 22 to rotate synchronously through the rotating shaft 25. Since the two worms 22 are meshed with the worm wheel 28, the rotating worm wheel 28 will drive the second nut 27 to rotate. The second nut 27 rotates on the second screw rod 26, and the second nut 27 drives the second screw rod 26 to rotate in the sleeve 24, so that the second screw rod 26 moves upward. As the second screw rod 26 continuously rises, the arc-shaped plate 29 at the top of the second screw rod 26 contacts the bottom of the base 1, realizing the limit of the base 1. Since the two second screw rods 26 rise or fall simultaneously, the base 1 can be made not to tilt and be in a horizontal state. Then, start to adjust the torsion angle of the torsion guide 32. Loosen the bolt 5 between the angle gauge 2 and the measuring plate 3 and the fixed seat 4, and then insert the sample rod 33 between the upper and lower wheels of the torsion guide 32. Adjust the opening degree of the upper and lower wheels of the torsion guide 32 to ensure that the center of the lower wheel of the torsion guide 32 is horizontal with the center of the upper wheel of the torsion guide 32. Since the torsion angle of the straight threaded steel bar with a nominal diameter of 12 mm is 22°, the torsion angle of the angle gauge 2 and the measuring plate 3 is set to 22°. Then tighten the bolt 5, and then adjust the worm of the torsion guide 32 to make the inclined plane above the sample rod 33 parallel to the lower part of the angle gauge 2, so as to complete the adjustment of the torsion angle of the torsion guide 32.

It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
