Description

A straightening device for eliminating internal stress in stainless steel wire Technical Field

[0001] This invention relates to the field of steel wire straightening technology, and specifically to a straightening device for eliminating internal stress in stainless steel wire. Background Technology

[0002] Steel wire is one of the four major types of steel products: plates, pipes, profiles, and wires. It is a reprocessed product made from hot-rolled wire rods through cold drawing. Classified by cross-sectional shape, it mainly includes round, square, rectangular, triangular, elliptical, flat, trapezoidal, and Z-shaped shapes. A straightening machine is a device used to straighten metal profiles, bars, pipes, and wires. The straightening machine uses straightening rollers to compress the bar or other material, changing its straightness to eliminate residual stress on the surface and in localized areas of the steel wire. Straightening machines generally have two rows of straightening rollers, and the number varies. There are also two-roll straightening machines, which rely on the angle change of the two rollers (a concave, hyperbolic roller) to straighten materials of different diameters. The main types include pressure straightening machines, balance roller straightening machines, shoe roller straightening machines, and rotary reverse bending straightening machines.

[0003] Chinese patent document CN213378993U discloses a wire rope straightening machine, which includes a frame and a straightening roller assembly. The straightening roller assembly is mounted on the frame and is divided into a horizontal straightening roller assembly and a vertical straightening roller assembly. A threaded rod and a limiting rod are vertically mounted on the frame. The plane containing the threaded rod and the limiting rod is perpendicular to the length direction of the frame. A first moving block and a second moving block are threadedly sleeved on the threaded rod, with the first moving block located above the second moving block. A first limiting block and a second limiting block are slidably sleeved on the limiting rod, with the first limiting block located above the second limiting block. Straightening rollers are rotatably connected between the first moving block and the first limiting block, and between the second moving block and the second limiting block. Annular straightening grooves are formed on the sidewalls of the straightening rollers. The straightening grooves on the two straightening rollers are correspondingly arranged. When the wire rope passes between the two straightening grooves, the wire rope can fit against the inner sidewall of the straightening groove.

[0004] However, the structural design of the aforementioned technologies requires that the distance between the straightening rollers be adjusted individually according to the diameter of the steel wire before straightening to ensure the straightening effect. However, errors are inevitable during the adjustment process, resulting in a large or small distance between the two straightening rollers, which affects the straightening effect. The straightening rollers need to be adjusted again during the straightening process, and the steel wire passing through the straightening rollers needs to be straightened again, thus affecting work efficiency.

[0005] Therefore, a straightening device for eliminating internal stress in stainless steel wire is proposed to solve the problems mentioned above. Summary of the Invention

[0006] This invention provides a straightening device for eliminating internal stress in stainless steel wire, aiming to solve the problem in related technologies where it is inconvenient to accurately adjust the distance between straightening rollers.

[0007] The present invention provides a straightening device for eliminating internal stress in stainless steel wire, comprising a main body, a mounting base on the main body, a locking component slidably connected to the inner bottom wall of the mounting base, straightening mechanisms slidably connected to both sides of the inner bottom wall of the mounting base, the two straightening mechanisms being elastically connected, and a guide component connected to the main body of the device being provided above the mounting base.

[0008] The straightening mechanism includes a straightening component slidably mounted on a mounting base and a measuring component mounted on the straightening component. The straightening component includes a slide plate slidably connected to the mounting base and multiple straightening elements rotatably connected to the slide plate. The straightening elements are slidably connected to a guide component, and the straightening elements in the two straightening mechanisms are staggered. The measuring component includes a mounting block mounted on the slide plate, a measuring roller rotatably connected to the top of the mounting block, a rack mounted on the mounting block, and a gear meshing with the rack. The gear is rotatably connected to the mounting base, and a locking component can limit the rack to lock the measuring roller.

[0009] When straightening the steel wire, the end of the wire is first straightened and then passed through locking assembly one, two measuring rollers, and two rows of straightening members in sequence. Finally, the end of the wire is connected to the main body of the equipment. As the wire passes through the two measuring rollers, the two measuring rollers drive the two sliding plates away from each other. At the same time, the sliding plates drive the straightening members on them away from each other, so that the straightening members can adapt to the diameter of the wire. When the bent wire passes through locking assembly one, it is blocked by locking assembly one and cannot pass through it. At this time, with the traction of the end of the wire, the bent wire can drive locking assembly one to move. As the wire continues to move, locking assembly one opens, allowing the bent wire to pass through locking assembly one. When locking assembly one moves to its limit position, locking assembly one can lock the rack, thereby limiting the sliding plate, and then limiting the straightening members on the sliding plate, so that the straightening members can straighten the bent wires that follow.

[0010] Preferably, a fixed seat is installed on one side of the inner bottom wall of the mounting base, and a wire inlet tube is installed on the top of one side of the fixed seat. The locking component is elastically connected to the other side of the fixed seat. A limiting component for limiting the reset of the locking component is provided on one side of the mounting base. Two baffles for preventing rack deviation are also installed on the inner bottom wall of the mounting base.

[0011] Preferably, the limiting component includes a pull rod, a slide rod, and a wedge, the wedge being located inside the mounting base, the slide rod being installed between the pull rod and the wedge, and the wedge being elastically connected to the inner wall of the mounting base.

[0012] During the movement of the locking component, it can push the wedge towards the inner wall of the mounting base and pass over the wedge. When the locking component locks the rack, the wedge resets and blocks the reset path of the locking component to ensure the stability of the straightening component during operation.

[0013] Preferably, the locking assembly includes a movable plate, a connecting plate, two sliders, two limiting blocks, and multiple limiting rods. The movable plate is slidably connected to the inner bottom wall of the mounting base and elastically connected to the fixed base. A guide groove is provided on the top of the movable plate, and the two sliders are slidably connected in the guide groove. The two limiting blocks are respectively installed on the two sliders. The connecting plate is installed on one side of the bottom of the movable plate, and the multiple limiting rods are installed on one side of the connecting plate. Multiple limiting holes for the insertion of the limiting rods are provided on the rack near the connecting plate.

[0014] Preferably, each of the two limiting blocks has an arc-shaped groove on one side opposite to the steel wire, and the arc-shaped grooves on the two limiting blocks can form a circular channel for the steel wire to pass through.

[0015] When the two limit blocks are in contact with each other, the circular channel between the two limit blocks can prevent the bent steel wire from passing directly between the two limit blocks. When the two limit blocks are separated, the channel between the two limit blocks expands, and the bent steel wire can pass through between the two limit blocks.

[0016] Preferably, the straightening component includes a connecting seat, a connecting shaft, and a straightening wheel. The connecting seat is mounted on the slide plate, the bottom end of the connecting shaft is rotatably connected to the connecting seat, and the straightening wheel is mounted on the outer side of the top end of the connecting shaft and located above the guide assembly.

[0017] Preferably, the measuring assembly further includes a connecting rod rotatably connected to the top of the mounting block, and the measuring roller is mounted on the connecting rod.

[0018] Preferably, the guiding assembly includes a guide plate and two limiting plates with beveled edges. The guide plate is mounted on the main body of the equipment. The guide plate has an installation groove. The two limiting plates are respectively mounted on both sides of the inner bottom wall of the installation groove. The top of the guide plate near the installation groove has two symmetrically arranged sliding grooves II. The connecting rod is slidably connected in the sliding grooves II. The top of the guide plate also has two rows of sliding grooves I for the sliding of the connecting shaft. The two rows of sliding grooves I are staggered. The inner bottom wall of the installation groove has a limiting groove for the movement of the movable plate. The two limiting blocks are located between the two limiting plates.

[0019] When the bent steel wire passes through the two limiting blocks, the bent steel wire can drive the movable plate to move through the limiting blocks. As the limiting blocks continue to move, the two limiting blocks gradually move away from each other along the inclined surface of the limiting plate, so that the bent steel wire can pass between the two limiting blocks. When the bent steel wire can pass between the two limiting blocks, the limiting rod can be inserted into the limiting hole of the rack, so that the rack can be limited, and thus the straightening parts on the slide can be limited.

[0020] Preferably, the straightening mechanism further includes a locking component two disposed at one end of the slide plate, wherein one end of the slide plate has a plurality of inclined grooves adapted to the locking component two.

[0021] Preferably, the second locking component includes a fixed plate and helical teeth that are elastically slidably connected to the fixed plate. The fixed plate is installed on the inner bottom wall of the mounting base, and the helical teeth are adapted to the helical grooves on the sliding plate.

[0022] By using the combination of inclined grooves and inclined teeth, the straightening wheels on the skateboard can be prevented from resetting after the steel wire is straightened, which makes it easy to straighten steel wires of the same diameter directly without the need to adjust the position of the straightening wheels a second time.

[0023] The beneficial effects of this invention, achieved by adopting the above technical solution, are as follows: When straightening a steel wire, the end of the wire is first straightened and then passed sequentially through a locking assembly, two measuring rollers, and two rows of straightening members. Finally, the end of the wire is connected to the main body of the equipment. During the wire's passage through the two measuring rollers, the two measuring rollers drive two sliding plates away from each other, and simultaneously, the sliding plates drive the straightening members on them away from each other, so that the straightening members can adapt to the diameter of the steel wire. This achieves automatic adjustment of the straightening members, while ensuring straightening accuracy, saving preparation time, and improving the efficiency of steel wire straightening. When the bent steel wire passes through… When the wire passes through the locking assembly, it is blocked by the locking assembly and cannot pass through it. At this time, with the traction of the wire end, the bent wire can drive the locking assembly to move between the two limiting plates, so that the locking assembly gradually contacts the inclined surface on the limiting plate. As the wire continues to move, the locking assembly opens, allowing the bent wire to pass through it. When the locking assembly moves to its limit position, it can lock the rack, thereby limiting the slide and then limiting the straightening component on the slide, so that the straightening component can straighten the bent wire.

Detailed Implementation

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] As shown in Figures 1 to 8, the straightening device for eliminating internal stress in stainless steel wire according to the present invention includes a main body 10, a limiting mechanism 20, a supporting mechanism 30, and a straightening mechanism 40. The limiting mechanism 20 is installed on the bottom side of one side of the main body 10. The supporting mechanism 30 is located above the limiting mechanism 20 and connected to the main body 10. There are two straightening mechanisms 40, both of which are mounted on the limiting mechanism 20 and slidably connected to the supporting mechanism 30. The gap between the two straightening mechanisms 40 is a wire straightening channel.

[0035] When straightening the steel wire, the end of the steel wire is straightened first, and then the end of the steel wire is passed through the straightening mechanism 40 and connected to the main body of the equipment 10. At this time, the subsequent steel wire can be pulled through the two straightening mechanisms 40 by the traction of the main body of the equipment 10 to straighten the steel wire.

[0036] As shown in Figures 1 to 4, the limiting mechanism 20 includes a mounting base 21, a fixed base 22, a cable inlet 23, a limiting component 24, a baffle 25, and a locking component 26. The mounting base 21 is installed on one side of the equipment body 10, and the fixed base 22 is installed on one side of the inner bottom wall of the mounting base 21. The cable inlet 23 is installed on the top side of one side of the fixed base 22, and the limiting component 24 is located on one side of the mounting base 21. The locking component 26 is elastically connected to one side of the fixed base 22. There are two baffles 25, symmetrically installed on the inner bottom wall of the mounting base 21. The baffle 25 near the fixed base 22 has a through groove for the locking component 26 to be inserted.

[0037] When straightening the steel wire, the end of the wire is first straightened and then passed sequentially through the inlet spool 23, locking assembly 26, and straightening mechanism 40, finally connecting to the main body 10 of the equipment. During the passage of the steel wire through the straightening mechanism 40, the distance between the two straightening mechanisms 40 can be adaptively adjusted according to the diameter of the steel wire. During the passage of the steel wire through the locking assembly 26, the bent portion of the wire can move the locking assembly 26 and lock the two straightening mechanisms 40, thus fixing the distance between them. This achieves the effect of automatically adjusting the straightening channel, reducing errors from manual adjustment.

[0038] As shown in Figures 2 and 3, the limiting assembly 24 includes a pull rod 241, a slide rod 242, a spring 243, and a wedge 244. The wedge 244 is located inside the mounting base 21. The slide rod 242 is installed between the pull rod 241 and the wedge 244. The spring 243 is sleeved on the outer side of one end of the slide rod 242 and installed between the inner wall of the mounting base 21 and the wedge 244. In the initial state, the wedge 244 is located on the movement path of the locking assembly 26.

[0039] As shown in Figures 2 to 5, the locking assembly 26 includes a movable plate 261, a slider 263, a limiting block 264, a connecting plate 265, a limiting rod 266, and a second spring 267. The movable plate 261 is slidably connected to the inner bottom wall of the mounting base 21. The second spring 267 is installed between the fixed base 22 and the movable plate 261 to drive the movable plate 261 to reset. The top of the movable plate 261 has a T-shaped guide groove 262. There are two sliders 263 and two limiting blocks 264. The two sliders 263 are slidably connected to both sides of the inner bottom wall of the guide groove 262. The bottoms of the two limiting blocks 264 are fixed to the tops of the two sliders 263, and each of the two limiting blocks 264 has an arc-shaped groove on its opposite side for a steel wire to pass through. When the two limiting blocks 264 come into contact, the arc-shaped grooves on the two limiting blocks 264 can form a circular channel for the steel wire to pass through. The inner diameter of the inlet cylinder 23 is larger than the circular channel formed by the two limiting blocks 264. The connecting plate 265 is installed on the bottom side of the movable plate 261 opposite to the spring 267, and the connecting plate 265 can be inserted into the through groove of the baffle 25. The limiting rods 266 are installed on one side of the connecting plate 265. There are multiple limiting rods 266, and the multiple limiting rods 266 are evenly distributed along the width direction of the connecting plate 265.

[0040] After the end of the steel wire passes through the inlet drum 23, it enters the arc-shaped groove of the limiting block 264. Then, the end of the steel wire continues to move and passes through the arc-shaped groove of the limiting block 264 into the straightening mechanism 40. When the steel wire bends after passing through the inlet drum 23, as the end of the steel wire moves, the bent steel wire cannot enter the arc-shaped groove of the limiting block 264 due to the obstruction of the limiting block 264. At this time, the bent steel wire can drive the limiting block 264 to move closer to the straightening mechanism 40. At the same time, the limiting block 264 drives the movable plate 261 to move closer to the straightening mechanism 40 through the slider 263. During the movement of the movable plate 261, it also drives the limiting rod 266 on the connecting plate 265 to move. When the movable plate 261 moves to the limit position, the connecting plate 265 enters the through groove of the baffle 25, so that the limiting rod 266 is inserted into the straightening mechanism 40, thereby locking the straightening channel between the two straightening mechanisms 40, so as to automatically adjust the straightening channel between the two straightening mechanisms 40.

[0041] During the movement of the movable plate 261, the movable plate 261 also contacts the wedge block 244 and pushes the wedge block 244 closer to the inner wall of the mounting base 21, at which time the spring 243 is compressed. When the limiting rod 266 is inserted into the straightening mechanism 40, the movable plate 261 passes the wedge block 244. At this time, the restoring force of the spring 243 can drive the wedge block 244 to reset, so that the wedge block 244 blocks the reset path of the movable plate 261, thereby limiting the movable plate 261 and preventing the limiting rod 266 from disengaging from the straightening mechanism 40 during the straightening of the steel wire, so as to ensure the stability of the steel wire straightening process.

[0042] As shown in Figures 1 to 2 and Figure 5, the support mechanism 30 includes a connecting arm 31 and a guide assembly 32. One side of the connecting arm 31 is mounted on the equipment body 10, and the bottom of the connecting arm 31 is mounted on the guide assembly 32. The movable plate 261 and the straightening mechanism 40 are both slidably connected in the guide assembly 32.

[0043] As shown in Figures 2 and 5-6, the guide assembly 32 includes a guide plate 321 and a limiting plate 326. The bottom of the connecting arm 31 is mounted on one side of the top edge of the guide plate 321. A mounting groove 324 is formed on the other side of the top edge of the guide plate 321. A limiting groove 325 is formed on the inner bottom wall of the mounting groove 324, and the movable plate 261 is slidably connected inside the limiting groove 325. There are two limiting plates 326, which are respectively mounted on both sides of the inner bottom wall of the mounting groove 324 and positioned close to the limiting groove 325. The opposite edges of the two limiting plates 326 each have a bevel. In the initial state, both limiting blocks 264 are located between the two limiting plates 326. Two symmetrically arranged sliding grooves 323 are formed on the top side of the guide plate 321 near the mounting groove 324. The top of the guide plate 321 is also provided with two rows of staggered slide grooves 322, both of which are located between the slide groove 323 and the connecting arm 31.

[0044] When the bent section of the steel wire passes the limiting block 264, the bent steel wire can drive the limiting block 264 to move between the two limiting plates 326 and approach the straightening mechanism 40. At the same time, the limiting block 264 drives the movable plate 261 to slide in the limiting groove 325 through the slider 263. As the movable plate 261 moves towards the end of the limiting groove 325, the limiting block 264 gradually contacts the inclined surface on the limiting plate 326. As the steel wire continues to move, the bent steel wire can push the two limiting blocks 264 to gradually move away. At this time, the bent steel wire can pass between the two limiting blocks 264 and enter between the two straightening mechanisms 40 for straightening.

[0045] During the movement of the movable plate 261, it also drives the limit rod 266 on the connecting plate 265 to move. When the movable plate 261 moves to the limit position, the connecting plate 265 enters the through groove of the baffle 25, so that the limit rod 266 is inserted into the straightening mechanism 40, thereby locking the two straightening components 41.

[0046] As shown in Figures 1 to 2 and Figure 6, the straightening mechanism 40 includes a straightening component 41, a measuring component 42, and a second locking component 43. The straightening component 41 is slidably connected to the inner bottom wall of the mounting base 21. The measuring component 42 is disposed on the straightening component 41 and slidably connected to the second sliding groove 323. The second locking component 43 is disposed on one side of the inner bottom wall of the mounting base 21 and inserted into one end of the straightening component 41.

[0047] After the end of the steel wire passes through the limiting block 264, it enters between the measuring components 42 of the two straightening mechanisms 40. As the wire passes through the two measuring components 42, it causes the two measuring components 42 to move away from each other, adjusting the distance between them. At this time, the diameter of the steel wire is measured by the two measuring components 42. During the movement of the measuring components 42, they drive the straightening components 41 connected to them to move, thereby adjusting the distance between the two straightening components 41 to automatically adapt to the diameter of the steel wire. After the two straightening components 41 have been adjusted, they are locked by the locking component 43 to prevent them from shifting during the straightening process, thus ensuring the stability of the steel wire straightening.

[0048] As shown in Figures 2 and 6 to 8, the straightening assembly 41 includes a sliding plate 411, straightening members, and inclined grooves 415. The sliding plate 411 is slidably connected to the inner bottom wall of the mounting base 21. There are multiple straightening members, which are evenly distributed along the length direction of the sliding plate 411. The straightening members on the two straightening assemblies 41 are slidably connected in two rows of sliding grooves 322. The inclined grooves 415 are formed at one end of the sliding plate 411 and are adapted to the locking assembly 43. There are multiple inclined grooves 415, which are evenly distributed along the width direction of the sliding plate 411.

[0049] As shown in Figures 6 to 8, the straightening component includes a connecting seat 412, a connecting shaft 413, and a straightening wheel 414. The connecting seat 412 is installed on one side of the slide plate 411. The bottom end of the connecting shaft 413 is rotatably connected to the connecting seat 412, and the top end of the connecting shaft 413 passes through the slide groove 322 and extends to the outside of the slide groove 322. The connecting shaft 413 is slidably connected to the slide groove 322. The straightening wheel 414 is installed on the outer side of the top end of the connecting shaft 413 to straighten the steel wire.

[0050] When the steel wire passes through the straightening rollers 414 in the two straightening mechanisms 40, the bent steel wire can be straightened by the compression of the straightening rollers 414.

[0051] As shown in Figures 2 to 7, the measuring assembly 42 includes a mounting block 421, a rack 422, limiting holes 423, a connecting rod 424, a measuring roller 425, and a gear 426. The mounting block 421 is mounted on one side edge of the slide plate 411, and the rack 422 is mounted on one side of the mounting block 421. A spring 44 is installed between the mounting blocks 421 in the two measuring assemblies 42. The racks 422 in both measuring assemblies 42 are located between the two baffles 25. The gear 426 meshes with the two racks 422, and the bottom end of the gear 426 is rotatably connected to the inner bottom wall of the mounting base 21. Multiple limiting holes 423 are provided on one side of the rack 422 near the movable plate 261. The multiple limiting holes 423 are evenly distributed along the length direction of the rack 422, and the limiting holes 423 are adapted to the limiting rod 266. The bottom end of the connecting rod 424 is rotatably connected to the top of the mounting block 421, and the top end of the connecting rod 424 is slidably connected to the inside of the slide groove 323. The bottom end of the measuring roller 425 is installed on the top end of the connecting rod 424, and the measuring roller 425 is set close to the mounting groove 324.

[0052] After the end of the steel wire passes through the limiting block 264, it enters between the two measuring rollers 425. As the wire passes through the measuring rollers 425, it pushes the rollers away from each other, adjusting the distance between them. The diameter of the steel wire is then measured by the two measuring rollers 425. During the movement of the measuring rollers 425, the mounting block 421 on the connecting rod 424 drives the connected slide plate 411 to move. The slide plate 411, through the connecting shaft 413, drives the straightening wheel 414 to move, automatically adjusting the position of the straightening wheel 414 to automatically adapt to the diameter of the steel wire. During the movement of the mounting block 421, it also drives the rack 422 on it to move, while the spring 44 is stretched. When the position of the straightening wheel 414 is adjusted, the locking assembly 43 locks the two slide plates 411 to prevent them from shifting during the straightening process, thus ensuring the stability of the straightening process.

[0053] When the bent steel wire moves the movable plate 261 via the limiting block 264, the movable plate 261 drives the limiting rod 266 to be inserted into the limiting hole 423 of the rack 422 via the connecting plate 265, thereby limiting the rack 422 and preventing it from moving. The limited rack 422 also limits the other rack 422 via the gear 426, thereby fixing the two measuring rollers 425 and further improving the stability of the steel wire straightening.

[0054] As shown in Figures 2 to 3 and Figure 8, the locking assembly 43 includes a fixed plate 431, a spring 432, and a helical tooth 433. The fixed plate 431 is installed on one side of the inner bottom wall of the mounting base 21. The spring 432 is installed between the fixed plate 431 and the helical tooth 433. A guide rod that is slidably connected to the fixed plate 431 is installed on the helical tooth 433. The helical tooth 433 is adapted to the inclined groove 415 on the slide plate 411. There are multiple springs 432, which are evenly distributed along the length of the fixed plate 431.

[0055] During the adjustment of the two measuring rollers 425, the measuring rollers 425 drive the slide plate 411 to move on the inner bottom wall of the mounting base 21. At this time, the slide plate 411 pushes the helical teeth 433 closer to the fixed plate 431 through the inclined groove 415, compressing the spring 432. When the measuring rollers 425 stop moving, the restoring force of the spring 432 drives the helical teeth 433 to reset and insert into the inclined groove 415 to limit the slide plate 411. When it is not necessary to straighten steel wires of other diameters, the helical teeth 433 prevent the slide plate 411 from resetting. When it is necessary to straighten steel wires of other diameters, the pull rod 241 drives the wedge block 244 closer to the inner wall of the mounting base 21. At this time, the movable plate 261 resets under the action of the spring 267, so that the limiting rod 266 moves out of the rack 422. Then, the helical teeth 433 are pushed closer to the fixed plate 431. At this time, the slide plate 411 resets under the action of the spring 44, so as to facilitate the subsequent straightening of steel wires of other diameters.

[0056] Working principle: When straightening the steel wire, the end of the steel wire is straightened first, and then the end of the steel wire is inserted into the arc groove of the limiting block 264 along the wire inlet 23. Then the end of the steel wire continues to move and passes through the arc groove of the limiting block 264 into the space between the two measuring rollers 425. Subsequently, the steel wire passes through the two rows of straightening rollers 414 and is connected to the main body of the equipment 10.

[0057] As the end of the steel wire passes through the two measuring rollers 425, it pushes the two measuring rollers 425 away from each other, at which point the two measuring rollers 425 measure the diameter of the steel wire. During the movement of the measuring rollers 425, the mounting block 421 on the connecting rod 424 drives the connected slide plate 411 to move. The slide plate 411, through the connecting shaft 413, drives the straightening wheel 414 to move, thereby automatically adjusting the position of the straightening wheel 414 to automatically adapt to the diameter of the steel wire. During the movement of the mounting block 421, it also drives the rack 422 on it to move, and the spring 44 is stretched. When the position of the straightening wheel 414 is adjusted, the helical teeth 433 insert into the inclined groove 415 to limit the slide plate 411, preventing the two slide plates 411 from shifting during the straightening of the steel wire, thus ensuring the stability of the steel wire straightening.

[0058] When the steel wire bends after passing through the inlet spool 23, as the end of the steel wire moves, the bent steel wire can drive the limiting block 264 to move between the two limiting plates 326 and approach the measuring roller 425. At the same time, the limiting block 264 gradually contacts the inclined surface on the limiting plate 326. As the steel wire continues to move, the bent steel wire can push the two limiting blocks 264 to gradually move away. At this time, the bent steel wire can pass between the two limiting blocks 264. While the limiting block 264 is moving, it also drives the movable plate 261 to approach the measuring roller 425 through the slider 263. During the movement of the movable plate 261, it drives the limiting rod 266 on the connecting plate 265 to move. When the movable plate 261 moves to the limit position, the connecting plate 265 enters the through groove of the baffle 25, so that the limiting rod 266 is inserted into the limiting hole 423 of the rack 422, thereby locking the two measuring rollers 425 and fixing the straightening channel for automatic adjustment of the straightening channel.

[0059] During its movement, the movable plate 261 also contacts the wedge 244 and pushes the wedge 244 closer to the inner wall of the mounting base 21, at which point the spring 243 is compressed. When the limiting rod 266 is inserted into the limiting hole 423 of the rack 422, the movable plate 261 passes the wedge 244. At this time, the force of the spring 243 can drive the wedge 244 to reset, so that the wedge 244 blocks the reset path of the movable plate 261, thereby limiting the movable plate 261 and preventing the limiting rod 266 from disengaging from the rack 422 during the straightening process, so as to further ensure the stability of the steel wire during the straightening process.
