Abstract
Description
Technical Field
[0001] This invention relates to the field of metal processing technology, and more specifically to a fixing device for preventing deformation of ferrous metal strips during rolling. Background Technology
[0002] Ferrous metal strip rolling mainly refers to a precision processing technology that uses forging (solid-state forming) to process iron, manganese, chromium and their alloys (such as steel, pig iron, etc.) and uses a rolling mill to plastically deform the steel strip in order to change its thickness, shape and microstructure.
[0003] A search revealed that Chinese patent CN118321348A discloses a fixing device for traction in metal rolling processing, including a mounting base. A traction roller is rotatably connected to the inner cavity of the mounting base. Mounting shafts are fixedly connected to both ends of the traction roller. A winding drum is sleeved on the outer wall of the traction roller. The mounting shafts rotate to drive the winding drum to rotate, and the winding drum is used to wind up the steel strip. By setting a fixing mechanism, one end of the steel strip is inserted into a transverse groove and then into a recessed groove. After completion, rotating a ratchet drives two clamping plates to move closer together to clamp and fix one end of the steel strip. This facilitates fixing one end of the steel strip to the outer wall of the winding drum. Furthermore, the fixing mechanism is located inside the traction roller, preventing the steel strip from being squeezed and deformed during winding.
[0004] While the above technical solution solves the problem of surface deformation during winding, it does not effectively eliminate the residual stress in the rolling process of metal strip. During the rolling process, residual stress is easily generated inside the metal strip. If the residual stress is not effectively eliminated, the metal strip is prone to warping, deformation and other defects during subsequent winding, storage or processing, which will affect product quality and performance.
[0005] Therefore, those skilled in the art have provided a fixing device to prevent deformation of ferrous metal strips during rolling, in order to solve the problems mentioned above. Summary of the Invention

[0011] The clamping assembly is slidably connected to the L-shaped guide plate and, under the intermittent push of the triggering mechanism linked to the driving mechanism, moves towards each other during the winding interval of the winding mechanism to clamp the metal strip, thereby straightening and positioning to prevent the metal strip from being squeezed and deformed during winding.
[0012] Preferably, the winding mechanism includes two support plates, which are located on the front and rear sides of the upper surface of the base plate, respectively. A winding roller is provided between the support plates. The winding roller has an installation cavity, and the installation cavity has an internal fixing structure.

[0015] Preferably, the stress relief mechanism includes two fixed plates, a stress relief roller is provided between the fixed plates, and a pressure roller is provided above the stress relief roller;
[0016] The stress-relieving roller includes a lower roller body with spiral ridges on its surface. The shafts at the front and rear ends of the lower roller body are rotatably connected to fixed plates. A sprocket is installed on the front shaft, and a sprocket is sleeved on it.
[0017] A dual-pass rotary joint is installed at the end of the rear shaft. An annular cooling water channel is provided in the lower roller body. Two water inlets and outlets are provided in the rear shaft body, which are connected to the annular cooling water channel to form a circulation loop.
[0018] Preferably, the drive mechanism includes a drive motor, which is mounted on a support plate. The motor shaft of the drive motor is connected to a drive shaft, and the drive shaft is provided with a notched main gear that meshes with the driven gear.
[0019] The drive shaft is also equipped with a turntable at one end, a main sleeve rod on the turntable, and a connecting rod that is rotatably connected to the main sleeve rod. The other end of the connecting rod is connected to a trigger mechanism.
[0020] Preferably, the triggering mechanism includes support rods installed on the front and rear sides of the base plate. Each support rod is provided with a limiting sleeve at its top. A push rod is slidably arranged inside the limiting sleeve. The push rod is restricted by the limiting sleeve so that it can only move left and right inside the limiting sleeve. A top rod is provided at the end of the push rod near the clamping assembly.
[0021] Preferably, the two push rods are connected by a U-shaped connecting frame. The bottom of the U-shaped connecting frame is provided with a limiting block, which is slidably connected to the upper surface of the base plate. One of the push rods has a sleeve rod at its end that is sleeved with one end of the connecting rod. The sleeve rod is rotatably connected to the end of the connecting rod.

[0025] The technical effects and advantages of this invention are as follows:
[0026] 1. The stress relief mechanism of the present invention has spiral raised texture on the surface of the lower roller body, which rubs the metal strip when it passes through, mechanically promoting the relaxation of its internal stress. At the same time, the annular cooling water channel inside the lower roller body provides uniform circulation cooling to the lower roller body, uniformly removing the residual heat after rolling of the metal strip, avoiding the generation of new thermal stress due to uneven cooling. The two-pronged approach promotes the release of internal stress, effectively eliminates residual stress, and prevents deformation.
[0027] 2. This invention utilizes the continuous rotation of the drive mechanism and the intermittent motion of the winding through the design of the main gear with a notch. During the interval, the linkage trigger mechanism pushes the clamping assembly to move, causing the side clamps on both sides to move towards each other, instantly clamping and straightening the stationary metal strip. This effectively corrects the deviation and waviness of the metal strip during its movement, ensuring that the wound metal strip is wound in the ideal state after straightening. This avoids the problem of compression deformation between the metal strips after winding and significantly improves the winding quality. Attached Figure Description

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0057] Example
[0058] Please see Figures 1 to 14 This embodiment provides a fixing device to prevent deformation of ferrous metal strip during rolling. The appearance and structural design of the device are as follows: Figures 1-4 As shown, it includes a base plate 1, which serves as a support plate. Various structures for mounting and fixing devices are installed on the base plate 1. A winding mechanism 2 is provided on the upper left side of the base plate 1. The winding mechanism 2 is used to wind up the rolled metal strip, facilitating its placement and subsequent use. An internal fixing structure 28 is provided inside the winding mechanism 2, which is installed inside the winding mechanism 2 (e.g., ...). Figure 6 As shown), it does not occupy its external space, so it will not cause interference when winding the metal strip, and thus will not squeeze the metal strip. This solves the problem in the prior art where the fixed structure (such as the external clamp) of the winding mechanism 2 squeezes the metal strip and causes deformation when winding the metal strip.
[0059] Furthermore, a stress relief mechanism 3 is installed on the upper right side of the base plate 1. The stress relief mechanism 3 includes a stress relief roller 32, which can rub and cool the stressed metal strip after rolling and before winding, promote the relaxation of internal stress in the rolled metal strip, eliminate or significantly reduce the residual stress in the metal strip after rolling, and prevent deformation during subsequent storage or processing. It works in conjunction with the winding mechanism 2 to further improve the anti-deformation ability of the rolled metal strip.
[0060] Furthermore, a drive mechanism 7 is provided on one side of the winding mechanism 2. The drive mechanism 7 intermittently drives the winding mechanism 2 to perform winding operations. At the same time, the winding mechanism 2 and the stress relief mechanism 3 are synchronously transmitted through a synchronization mechanism 4. The working states of the two are kept synchronized. The synchronization mechanism 4 is installed on the base plate 1 and plays the role of synchronous transmission, avoiding the problem of adding a power source to the stress relief mechanism 3 again, thus saving resources.
[0061] A guide straightening mechanism 5 is also provided at the upper center of the base plate 1, such as Figure 11As shown, the guiding and straightening mechanism 5 includes a base 51, an L-shaped guide plate 52 and a clamping assembly 53. The base 51 is set on the upper surface of the base plate 1, and two L-shaped guide plates 52 are symmetrically arranged on its front and rear sides. The L-shaped guide plates 52 can adjust the spacing on the base 51 to adapt to metal steel strips of different widths, guide and limit them, prevent the metal steel strip from running off-center, and improve the neatness and quality of winding.
[0062] Furthermore, a clamping assembly 53 is provided within the L-shaped guide plate 52, which can slide relative to it. The two clamping assemblies 53 can clamp the metal strip during the intermittent intervals when the winding mechanism 2 pauses. They are intermittently pushed by the drive mechanism 7 in conjunction with the trigger mechanism 6.
[0063] Under the action of the drive mechanism 7, the winding mechanism 2 winds up the metal strip. During the intermittent pause phase of the winding mechanism 2, the drive mechanism 7 continues to act on the trigger mechanism 6. During this period, the trigger mechanism 6 acts on the clamping components 53. The clamping components 53 on both sides of the stationary metal strip can quickly move towards each other to clamp the metal strip. This action occurs during the interval of the winding pause, which can suppress the slight deviation of the metal strip caused by inertia, and at the same time correct the deviation (lateral deviation) and longitudinal waviness defects caused by the internal stress accumulated during high-speed rolling and traction. During the clamping process, the clamping components 53 apply stable and powerful clamping from both sides of the edge, forming a rigid straightening fulcrum. This clamping force causes the internal stress of the metal strip to be released temporarily, and causes the original slightly waviness area to undergo beneficial slight plastic deformation, thereby achieving online straightening. Before each winding cycle restarts, the metal strip is already in a more ideal flat state, improving the winding quality from the source.
[0064] Each straightened metal strip is wound up in a consistent state, avoiding problems such as uneven winding, interlayer protrusions, or surface damage caused by local waviness or deviation. This results in a steel coil with neat edges, a tight structure, and no deformation. When the winding mechanism 2 stops and is about to restart, the drive mechanism 7 drives the trigger mechanism 6 to disengage from the clamping assembly 53. The clamping assembly 53 then automatically returns to its initial position and remains in a ready-to-work state, waiting for the next work cycle. Thus, the clamping assembly 53 completes the coordinated process of clamping, straightening, positioning, and disengagement during the winding stop.
[0065] The detailed structural description is as follows:
[0066] In this embodiment, as Figure 1 , Figures 5-8As shown, the winding mechanism 2 includes two support plates 21, which are located on the front and rear sides of the upper surface of the base plate 1 respectively. A winding roller 22 is provided between the support plates 21. The winding roller 22 has an installation cavity 26 inside, and an internal fixing structure 28 is provided inside the installation cavity 26. A feed port 27 is opened on the side wall of the installation cavity 26. The metal strip to be wound enters the installation cavity 26 from the feed port 27 and is then fastened by the internal fixing structure 28. Thus, when the winding roller 22 rotates to wind, the internal fixing structure 28 will not cause the metal strip to be squeezed and deformed, thereby improving the winding quality.
[0067] The internal fixing structure 28 includes a lower clamping plate 281 and a movable plate 282. The lower clamping plate 281 is located at the bottom of the mounting cavity 26. Its surface can be provided with anti-slip texture to increase friction and thus optimize the clamping and fixing effect. The movable plate 282 is placed in the mounting cavity 26 and can move up and down to adjust its displacement. The top of the movable plate 282 is provided with an electric push rod 283. The top of the electric push rod 283 is fixed to the inner top wall of the mounting cavity 26. After the electric push rod 283 is activated, it can drive the movable plate 282 to move up and down to adjust its position.
[0068] Multiple sleeves 284 are provided at the bottom of the movable plate 282. A sliding rod 286 is provided at the bottom of the sleeve 284. The bottom of the sliding rod 286 extends out of the sleeve 284 and is provided with an upper clamping plate 285. When the upper clamping plate 285 moves down, it interacts with the lower clamping plate 281 to clamp the metal strip. A compression spring 289 is connected to the upper end of the sliding rod 286. A top plate 288 is provided at the upper end of the compression spring 289. A pressure sensor 287 is fixed at the top of the sleeve 284 above the top plate 288. When the metal strip is not clamped and fixed, there is a gap between the top plate 288 and the pressure sensor 287.
[0069] During clamping operations, the electric actuator 283 moves the moving plate 282 downward, causing the sleeve 284 and the upper clamping plate 285 to move downward as well. After the upper clamping plate 285 contacts the metal strip, the electric actuator 283 continues to extend, causing the sliding rod 286 to move upward within the sleeve 284, which in turn causes the compression spring 289 and the top plate 288 to move upward. After the top plate 288 moves upward and contacts the pressure sensor 287, the electric actuator 283 continues to extend until the value of the pressure sensor 287 reaches the set value. At this point, the electric actuator 283 stops extending, and the upper clamping plate 285 and the lower clamping plate 281 can just clamp the metal strip, avoiding over-clamping and improving safety. Conversely, the electric actuator 283 shortens, eventually causing the upper clamping plate 285 to return to its original position for the next operation.
[0070] Both ends of the take-up roller 22 are rotatably connected to the support plate 21 through one-way bearings 23. The one-way bearings 23 prevent the take-up roller 22 from reversing after winding. One of the roller shafts of the take-up roller 22 is provided with a driven gear 24 and a main sprocket 25 at intervals. The driven gear 24 intermittently meshes with the drive mechanism 7, and the main sprocket 25 is connected to the synchronization mechanism 4. The drive mechanism 7 intermittently drives the driven gear 24 to rotate, so that the driven gear 24 causes the take-up roller 22 to perform intermittent winding operation. At the same time, the main sprocket 25 rotates with the driven gear 24 and also rotates intermittently, and transmits this motion state synchronously to the synchronization mechanism 4.
[0071] The specific structure of the synchronization mechanism 4 is as follows: Figure 1 and Figure 9 As shown, it includes a vertical plate 41, which is set on the base plate 1. An intermediate sprocket 42 is installed on its front side. The intermediate sprocket 42 is a concentric double wheel structure. One wheel is connected to the main sprocket 25 through the main chain 43, and the other wheel is connected to the stress relief mechanism 3 through the chain 44. Through the design of the synchronization mechanism 4, the intermittent rotation of the take-up roller 22 can be synchronized with the stress relief mechanism 3.
[0072] like Figure 2 and Figure 9 As shown, the stress relief mechanism 3 includes two fixed plates 31, with a stress relief roller 32 between the fixed plates 31. A pressure roller 33 is provided above the stress relief roller 32. A metal strip passes through the channel between the stress relief roller 32 and the pressure roller 33. The downward pressing and limiting effect of the pressure roller 33 facilitates the interaction between the stress relief roller 32 and the metal strip. The metal strip and the stress relief roller 32 below can be fully and tightly fitted, ensuring sufficient contact pressure for friction and heat conduction.
[0073] The stress-relieving roller 32 includes a lower roller body 321. The surface of the lower roller body 321 is provided with spiral ridges 322. When the lower roller body 321 rotates, the spiral ridges 322 generate a small, continuous axial force when they come into contact with the metal strip, which rubs the metal strip and promotes the relaxation of its internal stress, thereby achieving the effect of stress relief. The shafts 323 at the front and rear ends of the lower roller body 321 are rotatably connected to the fixed plates 31. A sprocket 324 is installed on the front shaft 323, and a sprocket 324 is sleeved on it, so that the synchronization mechanism 4 realizes the synchronous drive of the stress-relieving roller 32.
[0074] A dual-channel rotary joint 325 is installed at the end of the shaft 323 at the rear end. The dual-channel rotary joint 325 is connected to the external cooling mechanism. An annular cooling water channel is provided inside the lower roller 321. The shaft 323 at the rear end is provided with two inlets and outlets that are connected to the annular cooling water channel to form a circulation loop. The external cooling water flows in from the inlet, circulates in the annular cooling water channel, and flows out from the outlet. This uniformly and efficiently removes the high temperature heat of the metal strip after rolling, avoiding the generation of new thermal stress due to uneven cooling. By combining mechanical kneading and uniform heat dissipation, the residual stress of the metal strip after rolling can be eliminated or significantly reduced, preventing deformation during subsequent storage or processing.
[0075] The pressure roller 33 includes a mounting plate 331. The bottom of the mounting plate 331 is located above the lower roller body 321 and the upper roller body 332 is provided. An electric push rod 334 is provided at one diagonal of the mounting plate 331 and an insertion rod 333 is provided at the other diagonal. The bottom of the insertion rod 33 is located in the insertion hole 326 opened in the fixed plate 31, and the two are slidably connected.
[0076] When dealing with metal steel strips of different thicknesses, the height of the mounting plate 331 can be adjusted by adjusting the height of the electric actuator 334, thereby making the gap between the upper roller 332 and the lower roller 321 adjustable. This allows for the adaptation to metal steel strips of different specifications, improving practicality. During the upward or downward movement of the mounting plate 331, the insertion rod 333 moves upward or downward within the insertion hole 326, improving the stability of the movement process.
[0077] like Figure 10 As shown, the drive mechanism 7 includes a drive motor 71, which is mounted on the support plate 21. The motor shaft of the drive motor 71 is connected to the drive shaft 72. The drive shaft 72 is provided with a main gear 73 with a notch that meshes with the driven gear 24. Because the main gear 73 has a notch, it does not mesh with the driven gear 24 when it rotates one revolution. The rotation time of the notch is the pause interval of the winding. The rotation time of the notch is also the time for the clamping assembly 53 to straighten and position the stopped metal strip.
[0078] Furthermore, a turntable 74 is provided at the end of the drive shaft 72. A main sleeve rod 75 is provided on the turntable 74. A connecting rod 76 is rotatably connected to the main sleeve rod 75. The other end of the connecting rod 76 is connected to the trigger mechanism 6. During the winding process, the drive motor 71 is always in working state, but the winding state is intermittent. The drive motor 71 continuously drives the turntable 74 to rotate. Thus, through the action of the main sleeve rod 75 and the connecting rod 76, the connecting rod 76 can periodically pull the trigger mechanism 6 to move left and right along the winding direction of the metal strip. This can push the clamping assembly 53 to form a periodic intermittent clamping action on the metal strip when it stops.
[0079] like Figure 11 and Figure 12 As shown, the triggering mechanism 6 includes support rods 61 located on the front and rear sides of the base plate 1. Each support rod 61 is provided with a limiting sleeve 62 at its top. A push rod 63 is slidably arranged inside the limiting sleeve 62. The push rod 63 is restricted by the limiting sleeve 62 so that it can only move left and right within the limiting sleeve 62, thereby achieving the effect of pushing left and right. A top rod 64 is provided at the end of the push rod 63 near the clamping assembly 53. When the push rod 63 moves towards the clamping assembly 53, the top rod 64 can squeeze the two clamping assemblies 53 in front and behind to move closer to each other, thereby clamping the metal steel strip. Conversely, when the push rod 63 moves away from the clamping assembly 53, the clamping assembly 53 returns to its original position by its self-restoring force.
[0080] The two push rods 63 are connected by a U-shaped connecting frame 65. The bottom of the U-shaped connecting frame 65 is provided with a limiting block 66, which is slidably connected to the upper surface of the base plate 1. The U-shaped connecting frame 65 can keep the two push rods 63 moving synchronously, while the limiting block 66 at the bottom keeps them stable during movement. One of the push rods 63 has a sleeve rod 67 at its end that is sleeved with one end of the connecting rod 76. The sleeve rod 67 is rotatably connected to the end of the connecting rod 76. Through this structural design, the connecting rod 76 can pull the push rod 63 to move back and forth as the turntable 74 moves, thereby triggering the clamping assembly 53.
[0081] like Figure 11 , Figure 13 and Figure 14 As shown, the base 51 includes a slide rail 511, and two sliders 512 distributed front and back are provided in the slide rail 511. A bidirectional lead screw 513 is passed through the two sliders 512. An adjustment motor 514 is installed at one end of the bidirectional lead screw 513, and an L-shaped guide plate 52 is provided on the slider 512.
[0082] Since the metal strip may have different widths, in order to maintain the guiding effect, after the adjusting motor 514 is started, it can make the bidirectional lead screw 513 rotate, thereby causing the two sliders 512 to move closer or further away from each other, which in turn drives the L-shaped guide plate 52 at its upper end to move closer or further away from each other, thereby realizing the adjustment of the distance between the two to adapt to metal strips of different specifications.
[0083] The clamping assembly 53 includes a side clamping plate 531, elastic columns 532, and a pushing structure 533. The side clamping plate 531 is located in the cavity inside the L-shaped guide plate 52. Elastic columns 532 are symmetrically arranged on the opposite side of the side clamping plate 531. The pushing structure 533 is located between the two elastic columns 532. The push rod 64 in the triggering mechanism 6 interacts with the pushing structure 533 to push the pushing structure 533 toward the metal strip. This causes the side clamping plate 531 to move together to clamp the metal strip and causes the elastic columns 532 to stretch and deform. When the push rod 64 disengages from the pushing structure 533, the side clamping plate 531 loses its clamping state on the metal strip under the action of the elastic columns 532. During the winding process, the side clamping plate 531 maintains a distance of 0.5-1mm from the metal strip, which serves as a guide while preventing wear.
[0084] The side clamp 531 includes a plate body 5311. The plate body 5311 has a wear-resistant layer 5312 on the side near the metal steel strip. The wear-resistant layer 5312 is made of a wear-resistant and relatively soft material, such as high molecular weight polyethylene (PE1000) or polyurethane (PU). These materials are wear-resistant and their hardness is much lower than that of the metal steel strip. When micro-slip occurs, they will be worn down on their own, instead of the metal steel strip being scratched, thus protecting the metal steel strip. An elastic layer 5313 is provided between the wear-resistant layer 5312 and the plate body 5311. It can undergo slight deformation when clamping the metal steel strip to avoid over-clamping.
[0085] The elastic column 532 includes a connecting plate 5321. One end of the connecting plate 5321 is fixed to the outer wall of the L-shaped guide plate 52, and the other end is provided with a telescopic rod 5322. A tension spring 5323 is sleeved on the telescopic rod 5322. One end of the tension spring 5323 is fixed to the connecting plate 5321, and the other end is fixed to the plate body 5311. Initially, the tension spring 5323 pulls the plate body 5311 to remain stationary. However, when the pushing structure 533 pushes the plate body 5311 to achieve the clamping action, the plate body 5311 is displaced, thereby stretching the tension spring 5323. The telescopic rod 5322 also extends. However, when the pushing force of the pushing structure 533 disappears, the plate body 5311 returns to its original position under the action of the tension spring 5323, losing the clamping effect on the metal steel strip.
[0086] The pushing structure 533 includes a fixed sleeve 5331, one end of which is fixed to the plate 5311. A movable rod 5332 is slidably connected inside the fixed sleeve 5331. The movable rod 5332 is fixed to the fixed sleeve 5331 by a screw 5334. At the same time, an inclined block 5333 is provided at the end of the movable rod 5332. The inclined block 5333 interacts with the push rod 64. The push rod 64 pushes the inclined block 5333, which moves towards the metal strip. In other words, the entire pushing structure 533 moves, which in turn moves the side clamping plate 531 towards the metal strip to achieve clamping.
[0087] It should be noted that loosening the screw 5334 adjusts the length of the movable rod 5332. The purpose of adjusting the length is to keep the distance between the inclined block 5333 and the push rod 64 constant. Since the distance the push rod 64 moves each time is constant, only by maintaining a constant relative distance between them can the clamping effect be consistent each time. The adjustable length of the movable rod 5332 is designed for this purpose. The length of the movable rod 5332 is related to the distance between the two L-shaped guide plates 52. The distance between the two L-shaped guide plates 52 will be adaptively adjusted according to the width of the metal strip. Therefore, the initial position of the two L-shaped guide plates 52 can be fixed. When they need to move closer to each other, the distance they move is the distance that the movable rod 5332 needs to be extended. Conversely, when the two L-shaped guide plates 52 move further apart, the distance they move is the distance that the movable rod 5332 needs to be shortened.
