[0002] With the development of the metal manufacturing industry, most blanks and forgings undergo bending deformation due to stress concentration after heat treatment or blanking, requiring straightening before proceeding to the next process. Straightening lighter and shorter workpieces is relatively easy, but straightening longer and heavier workpieces is more difficult, especially when there is bending in different directions. For example, scrapers in mining equipment are about 1.7m long and weigh about 150kg; straightening them is time-consuming, labor-intensive, and poses significant safety hazards.

[0003] Therefore, in order to solve the problem that long-distance workpieces often require repeated straightening with little effect due to inaccurate positioning and improper clamping during the straightening process, there is an urgent need for a safe, reliable and efficient metal workpiece straightening and clamping device for long-distance and heavy workpieces. Summary of the Invention

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0022] To achieve the above objectives, this application provides the following technical solution: The straightening and clamping device for metal workpieces disclosed in this invention is mainly used in the traditional straightening process of metal workpieces. The assembly and disassembly process is cumbersome, and it is impossible to achieve multi-angle straightening. Repeated re-clamping is required, resulting in low straightening accuracy and low work efficiency. It is especially suitable for various long-distance metal workpiece processing scenarios that require straightening in multiple directions.

[0023] like Figures 1 to 4 As shown, the present invention is a metal workpiece straightening and clamping device, comprising: a fixed plate 1; a clamping device 2, wherein there are at least two clamping devices 2, which are slidably arranged on the fixed plate 1 along the length direction of the metal workpiece and the spacing is adjustable; and a rotating device 3, which is disposed at one end of the fixed plate 1, the rotating device including a clamping member 31 and a rotating member 32, the clamping member 31 being used to clamp the metal workpiece, and the rotating member 32 being connected to the clamping member 31 to drive the clamping member 31 to rotate.

[0024] During the straightening and clamping of the metal workpiece, one end of the workpiece to be straightened is clamped in the clamping member 31 of the rotating device 3. The end of the workpiece is locked and fixed by the adjustment structure of the clamping member 31 to prevent displacement during the straightening process. Then, according to the actual length of the workpiece, the distance between the two clamping devices 2 on the fixed plate 1 is slidably adjusted so that the metal workpiece is stably placed in the U-shaped groove of the clamping device 2. The locking mechanism of the clamping device 2 is activated, and the metal workpiece is clamped and fixed in all directions through the U-shaped groove. At this time, the workpiece is in a stable horizontal state, and the operator can perform the straightening operation on the workpiece in the first angle direction. After the straightening in this direction is completed, the clamping device 2 is driven to unlock the metal workpiece, and the rotating member 32 drives the metal workpiece to rotate precisely to the preset second angle. After rotation, the clamping device 2 is activated again to clamp and fix the metal workpiece again, and then the straightening operation in the second angle is performed. If straightening in more angles is required, the above steps of unlocking, rotating, and clamping straightening can be repeated until the straightening requirements in all directions are met. This device adopts an open structure design, eliminating the need to disassemble the device during the loading and unloading of metal workpieces, making operation convenient and efficient. Through the cooperation of the rotating device and the sliding clamping device, multi-angle straightening can be achieved without re-clamping, avoiding positioning errors caused by repeated clamping and significantly improving straightening accuracy. At the same time, the adjustable-spacing clamping device is suitable for metal workpieces of different lengths and specifications, with strong versatility, greatly improving the flexibility and efficiency of straightening operations and ensuring the processing quality of metal workpieces.

[0025] In some embodiments, the fixing plate 1 is provided with at least two parallel guide rails 11, and the pressing device 2 is slidably connected to the guide rails 11 through a groove.

[0026] The upper surface of the fixed plate 1 is fixedly provided with two parallel elongated guide rails 11 along its length. Correspondingly, the bottom of the pressing device 2 is integrally formed or fixedly connected with a sliding groove that precisely matches the guide rails. Through the sliding engagement of the guide rails 11 and the sliding groove, the pressing device 2 can slide smoothly along the longitudinal direction of the fixed plate 1. The inner contour dimension of the sliding groove is slightly larger than the outer contour dimension of the guide rails 11, with a small fitting gap between them to ensure smooth sliding. At the same time, the guide rails extend along the length of the fixed plate 1, effectively restricting the degree of freedom of the pressing device 2 in other directions in the horizontal plane, retaining only the degree of freedom of movement along the length of the guide rails. For easy fine adjustment and fixation, a length scale is engraved on one side of the fixed plate 1, and a locking bolt is provided on the side of the pressing device 2. When the pressing device 2 slides to the target position, rotating the locking bolt will make it laterally press against the guide rails 11 or press against the table surface of the fixed plate 1, thereby achieving a firm lock in position. The above design, through the cooperation of guide rail 11 and slide groove, achieves smooth adjustment of the spacing of clamping devices 2 on fixed plate 1. The operator can directly push clamping devices 2 to the required position, and with the help of a scale, quantitative and precise spacing settings can be made to adapt to metal workpieces of different lengths, making it highly versatile. The double parallel guide rail structure provides good guiding accuracy, ensuring that the movement trajectory of two or more clamping devices 2 is always along the length direction of fixed plate 1. The slide groove structure at the bottom of clamping device 2 enables clamping device 2 to withstand the huge radial pressure generated during the straightening process, ensuring the stability of the entire clamping device under force. Quick and reliable locking can be achieved through simple mechanical locking bolts, preventing the clamping devices 2 from shaking during the straightening operation, ensuring the repeatability of the process and the consistency of the straightening effect.

[0027] In some embodiments, the clamping device 2 includes a clamping block 21 and a U-shaped groove 22. There is at least one clamping block 21 disposed on the inner wall of the U-shaped groove 22. The clamping block 21 is used to clamp and lock the metal workpiece in the U-shaped groove 22.

[0028] Among them, reference Figure 4The clamping device 2 includes a U-shaped groove 22 as the main structure and at least one clamping block 21. The upper part of the U-shaped groove 22 has an upward-opening U-shaped groove. The clamping block 21 is a wedge-shaped block or an arc-shaped block. The clamping block 21 can be movably installed on one side of the inner wall of the U-shaped groove using a locking bolt, or it can be directly fixed to one side of the inner wall of the U-shaped groove. Specifically, a horizontal threaded hole is machined on one side of the inner wall of the U-shaped groove 22, and the locking bolt passes through this threaded hole to connect to the back of the clamping block 21. Rotating the nut located on the outside of the U-shaped groove 22 with the locking bolt drives the clamping block 21 to move towards or away from the center of the U-shaped groove 22 along a direction perpendicular to the length of the metal workpiece. When the metal workpiece is placed in the U-shaped groove 22, rotating the locking bolt applies pressure to the side of the workpiece with the clamping block 21, firmly clamping and locking the metal workpiece to the opposite inner wall of the U-shaped groove 22. This embodiment constructs a highly efficient and reliable metal workpiece clamping device through the combination of U-shaped groove 22 and clamping block 21. The U-shaped groove 22 provides radial positioning and bottom support for the metal workpiece, achieving initial centering upon placement, simplifying the alignment steps during clamping and improving work efficiency. The side-clamping method avoids the indentation or damage that can occur on the workpiece surface with traditional top-down clamping, making it particularly suitable for straightening machined or precision metal workpieces requiring high surface quality. The entire clamping device has a simple structure and low manufacturing cost. The bolt-driven mechanical clamping generates a large and stable locking force, effectively resisting the reverse force and vibration generated during straightening, ensuring no displacement of the metal workpiece during processing and guaranteeing straightening accuracy.

[0029] In some embodiments, the clamping device 2 further includes a drive member for driving the clamping block 21 to move toward or away from the metal workpiece.

[0030] Reference Figures 2 to 4 The clamping device also includes a drive component as a power source. The drive component is one or more of a hydraulic lever, cylinder, or electric push rod. The drive component is connected to the clamping block 21. When clamping a metal workpiece, the drive component moves the clamping block 21 smoothly toward the metal workpiece placed in the U-shaped groove 22 until it contacts the workpiece and applies a preset clamping force. When unlocking the metal workpiece, the drive component moves the clamping block away from the workpiece. This embodiment, by introducing a drive component, achieves power-based clamping operation. Compared to manually locking bolts, the drive component, controlled by an electronic control system, only requires operation of the control valve to instantly complete the clamping and unlocking actions, greatly reducing operation time and labor intensity, achieving automated clamping, and significantly improving clamping efficiency. All of the above-mentioned drive components can accurately adjust and stably maintain the output force, ensuring consistency and reliability during the metal workpiece clamping process, avoiding clamping force fluctuations caused by human error, thereby achieving stable straightening quality and protecting the workpiece surface.

[0031] In some embodiments, there are two clamping blocks 21, which are arranged parallel to each other and opposite to each other in the U-shaped groove 22.

[0032] Reference Figure 1 The clamping device 2 contains two clamping blocks 21, namely a first clamping block 21a and a second clamping block 21b, which are arranged parallel to each other on the inner walls of the two sides of the U-shaped groove 22. The clamping surfaces of the first clamping block 21a and the second clamping block 21b are machined to fit the size of the metal workpiece to be clamped. When clamping is performed, the driving component drives the first clamping block 21a and the second clamping block 21b to move towards each other, simultaneously contacting and applying clamping force from both sides of the metal workpiece. When an unlocking signal is received, the two clamping blocks are driven to move away from each other, releasing the constraint on the metal workpiece. This embodiment uses two parallel and oppositely arranged clamping blocks and corresponding driving components to form an active clamping mechanism. The two clamping blocks apply clamping force to the middle from both sides perpendicular to the length direction of the metal workpiece, providing accurate positioning for subsequent high-precision straightening. The first clamping block 21a and the second clamping block 21b are distributed on both sides of the workpiece, avoiding local stress concentration. When a large clamping force is applied, the risk of elastic deformation or even indentation of the workpiece due to clamping can be significantly reduced. Simultaneous fixation of the metal workpiece from both sides greatly improves the radial and axial rigidity of the metal workpiece within the U-groove 22. During the straightening process, regardless of the direction of the straightening force, it is difficult for the metal workpiece to undergo even slight rotation or movement at the clamping point, ensuring the accuracy and effectiveness of the straightening force and enhancing the stability of the entire process system.

[0033] In some embodiments, the clamping block 21 includes a fixed end clamping block 21a and a free end clamping block 21b. The free end clamping block 21b is connected to a driving member, which drives the free end clamping block 21b to move toward or away from the fixed end clamping block 21a.

[0034] Among them, reference Figure 1The clamping block 21 specifically includes a fixed-end clamping block 21a and a free-end clamping block 21b. The fixed-end clamping block 21a is fixedly connected to the inner wall of one side of the U-shaped groove 22, and its position is fixed and cannot be adjusted. The free-end clamping block 21b is connected to the output end of the drive unit, which is fixedly installed on the outer wall of the other side of the U-shaped groove 22. The clamping surface of the fixed-end clamping block 21a provides a reliable positioning reference for the workpiece, and the clamping surface of the free-end clamping block 21b has the same shape as the fixed-end clamping block 21a. When it is necessary to clamp a metal workpiece, the metal workpiece is placed in the U-shaped groove 22 with one side pressed against the positioning surface of the fixed-end clamping block 21a. Then, the drive unit is activated, causing the drive unit to drive the free-end clamping block 21b to move precisely toward the fixed-end clamping block 21a until the metal workpiece is clamped from the other side, and a preset clamping force is applied. When the metal workpiece needs to be unlocked, the drive unit moves the free end clamping block 21b away from the fixed end clamping block 21a. This embodiment designs the fixed end clamping block 21a and the free end clamping block 21b to have both reference and active clamping modes. Since the fixed end clamping block 21a provides a stable and unchanging positioning reference, the operator only needs to bring the metal workpiece close to this reference and then control the drive unit to clamp the free end clamping block 21b, simplifying the operation process and improving clamping efficiency. The fixed end clamping block 21a, as a positioning reference, ensures that the reference position of the metal workpiece relative to the U-shaped groove 22 remains unchanged when the same workpiece is clamped multiple times or when different workpieces are clamped sequentially. This eliminates positioning errors that may be introduced by changes in the initial positions of the clamping blocks on both sides, greatly improving the accuracy of repeated clamping positioning. Compared to designs that require driving components on both sides, this embodiment only requires one set of driving components to act on the free end clamping block 21a. While satisfying the core clamping function, it simplifies the structure, reduces manufacturing costs and maintenance complexity, and makes the overall size of the clamping device 2 more compact, saving on the manufacturing cost of the device.

[0035] In some embodiments, the rotating device 3 and the clamping device 2 are arranged along the length of the metal workpiece; the rotating device 3 is used to drive the metal workpiece to rotate from 0 to 360 degrees. o Rotate within the range to any target angle.

[0036] Reference Figure 1 and Figure 4 The rotating device 3 and the clamping device 2 are arranged along the length of the metal workpiece. The rotating device 3 is fixedly installed at one end of the fixed plate 1. Driven by the rotating drive mechanism, the rotating device drives the metal workpiece to rotate from 0 to 360 degrees. oThe rotation can be adjusted to any target angle within the specified range. The rotary drive mechanism can be one or more of a worm gear mechanism and a gear transmission mechanism. The rotary drive mechanism is connected to the rotary device 3, which includes a clamping member 31 and a rotating member 32. The clamping member 31 is a two-jaw chuck. The rotary drive mechanism can drive the two-jaw chuck and the metal workpiece it clamps to rotate 0~360 degrees in the horizontal plane. o The rotation of the workpiece is achieved through a combination of a rotary drive mechanism and a rotary device 3. This allows for precise angular rotation of the metal workpiece while it is clamped, enabling multi-angle straightening with a single clamping operation and significantly improving the efficiency of clamping and straightening the metal workpiece. The rotary device 3 quickly and accurately rotates the metal workpiece to any target angle, thereby continuously straightening the workpiece's curvature on different radial planes. This eliminates the cumbersome process of disassembling and repositioning the workpiece after each change of straightening surface, a problem common in traditional processes, resulting in a several-fold increase in straightening efficiency. The rotary device 3 rotates smoothly and has a self-locking function, ensuring stable and safe operation. The worm gear mechanism provides smooth transmission without impact. Once the target angle is reached, the rotary device 3 automatically locks, effectively resisting vibrations during the straightening process and preventing accidental rotation of the workpiece, thus ensuring operational accuracy and process safety.

[0037] In some embodiments, a locking mechanism is also included, disposed between the pressing device 2 and the fixing plate 1, for operably locking the position of the pressing device 2 on the fixing plate 1.

[0038] Reference Figure 1 , Figure 2 and Figure 4The metal workpiece straightening and clamping device also includes a locking mechanism, which is located between the clamping device 2 and the fixed plate 1. This locking mechanism securely locks the clamping device 2 onto the fixed plate 1 during use. The locking mechanism includes locking bolts and locking blocks. The locking blocks are rectangular or trapezoidal blocks, with their bottom surfaces abutting the upper surface of the fixed plate 1. Parallel slots or threaded holes extending transversely through the fixed plate are spaced along one side of the guide rail 11 on the fixed plate 1. The locking blocks are adjustablely fixed to the target position through these slots or threaded holes. Correspondingly, locking bolts are installed on the clamping block 21b near the free end of the clamping device 2. When the clamping device 2 slides along the guide rail 11 to the target position, the side locking bolts correspond precisely to the lower locking blocks. By tightening the locking bolts, their lower ends forcefully press against the upper surface of the locking blocks. Utilizing the resulting static friction, the clamping device 2 and the fixed plate 1 are firmly secured together, thus completely restricting the sliding freedom of the clamping device 2. This embodiment provides a reliable locking mechanism for the position of the clamping device 2 through a mechanical locking mechanism that uses a locking block and a locking bolt. During straightening operations, the clamping device 2, as the main force-bearing support point, will withstand the huge radial force from the bending and springback of the metal workpiece. This locking mechanism can rigidly connect the clamping device 2 to the fixed plate 1, ensuring the static and dynamic rigidity of the entire clamping system. By preset or adjusting the locking block to the standard scale position of the fixed plate 1, combined with the sliding adjustment of the clamping device 2 itself, the precise setting of the spacing of the clamping device 2 can be achieved. After locking, the position of the clamping device 2 remains unchanged, ensuring that the support point position is completely consistent even when clamping the same metal workpiece multiple times, thus guaranteeing the repeatability and consistency of the clamping process. The locking mechanism itself adopts a mechanical structure, which is simple and reliable, has low maintenance costs, and improves the ease of operation and reliability of the device.

[0039] In some embodiments, the locking mechanism includes a locking block disposed between the fixing plate 1 and the locking bolt of the pressing device 2, for fixing the pressing device 2 onto the fixing plate 1.

[0040] The locking mechanism includes a locking block, which is specifically positioned between the upper surface of the fixed plate 1 and the locking bolt of the clamping device 2, forming a series pressure transmission path from the clamping device 2 to the locking bolt to the locking block to the fixed plate 1, used to fix the clamping device 2 onto the fixed plate 1. The locking block can move on the fixed plate 1 for pre-fixation. A locking bolt is installed on one side of the U-shaped groove 22 of the clamping device 2. The locking block, acting as a pressure-bearing pad, converts the concentrated force of the locking bolt into a stable surface pressure on the fixed plate 1. The resulting friction is sufficient to resist the severe radial impact and vibration during the straightening process, ensuring that the clamping device does not shift under force. This embodiment achieves reliable locking of the clamping device 2 by introducing an independent, positionable locking block as a force transmission medium. The locking block can move and be fixed independently on the surface of the fixed plate 1, providing additional and finer adjustment capability for the locking position of the clamping device 2. The locking block bears the clamping force of the locking bolt, effectively preventing deformation or damage to the working surface of the fixing plate 1, extending the service life of the main structure of the device, and maintaining long-term accuracy.

[0041] Reference Figures 1 to 4 This application also provides a method for straightening metal workpieces using a metal workpiece straightening clamping device, comprising the following steps: Adjust and fix the spacing between the two U-shaped grooves 22 according to the length of the metal workpiece; The metal workpiece is placed in the U-shaped groove 22 and the metal workpiece is pressed and locked by the clamping device 2 to straighten the first angle. The metal workpiece is unlocked by the clamping device 2, and the metal workpiece is driven to rotate to the second angle by the rotating device 3. The metal workpiece is clamped and locked by the clamping device 2 to perform the second angle straightening.

[0042] In this process, based on the length of the metal workpiece to be straightened, two clamping devices 2 slide along the guide rail 11 on the fixed plate 1, so that the distance between the two U-shaped grooves 22 matches the required support point position of the workpiece. Then, the locking bolts on the side of each clamping device 2 are operated, so that their lower ends press against the locking blocks below, thereby locking the clamping device 2 in the target position on the fixed plate 1. One end of the metal workpiece is inserted into the clamping member 31 of the rotating device 3 and clamped. The metal workpiece is placed in the two U-shaped grooves 22 that have been adjusted in position, and the driving member of each clamping device 2 is operated to drive the free end clamping block 21b to move, pressing and locking the metal workpiece in the U-shaped groove 22. At this time, the driving member drives the free end clamping block 21b to apply pressure at the corresponding bending point to perform the straightening operation in the first angular direction. After completing the first angle alignment, operate the driving component to move the free end clamping block 21b of the clamping device 2 away from the fixed end clamping block 21a, unlocking the clamping lock of the metal workpiece; operate the rotation driving mechanism of the rotating device 3 to drive the metal workpiece and the clamping component 31 to rotate precisely 90 degrees.o Or any other target angle. After the metal workpiece is rotated to the second angle, the drive of the clamping device 2 is operated again to drive the free end clamping block 21b to move toward the fixed end clamping block 21a, thereby re-clamping and locking the metal workpiece in the second angular direction. This process can be repeated as needed to straighten the metal workpiece in multiple directions. This embodiment details how to use the structure of this device to achieve efficient and high-precision straightening operations, realizing one-time clamping and multi-angle straightening. This method utilizes the cooperation of a lockable sliding clamping device and a rotating device to achieve one-time clamping operation after the workpiece is supported and positioned in the length direction.

[0043] The metal workpiece straightening and clamping device described in this application is an adjustable and rotatable multi-functional clamping device that enables the clamping of metal workpieces of different lengths and rotation at different angles, greatly improving the straightening efficiency of metal workpieces. This application relates to a metal workpiece straightening and clamping equipment, primarily serving as an auxiliary clamping and flipping device for the straightening of longer metal workpieces. In the metal manufacturing industry, long-distance metal workpieces often experience deformation due to heat treatment or bending deformation after blanking. To ensure that the workpiece's performance remains unchanged, straightening is necessary. The metal workpiece straightening and clamping device provided in this application ensures the optimal clamping position of the metal workpiece during straightening, and after straightening one side of the metal workpiece, it can rotate the workpiece to straighten the other side, achieving clamping of workpieces of different lengths at different positions. Furthermore, the ability to rotate the metal workpiece successfully solves the problem of clamping and positioning metal workpieces at different angles and positions. This ensures both the quality of the metal workpiece and accelerates the straightening efficiency, increasing processing efficiency by more than 30%.
