Description

Technical Field

[0001] This invention relates to the field of straightening equipment technology, specifically to a multi-roller straightening device and straightening process for beryllium nickel copper alloy T-shaped profiles. Background Technology

[0002] In the extrusion and drawing process of T-profiles, most of the upper and lower clamping rollers and left and right clamping rollers of the existing straightening equipment adopt a fixed installation structure, and the clamping distance between the rollers cannot be adjusted. When the production task is switched between different specifications of T-profiles, the equipment cannot flexibly adjust the clamping distance according to the actual height and flange width of the T-profile, resulting in poor equipment versatility. Different specifications of products need to be equipped with multiple sets of straightening equipment or frequently replace roller assemblies, which increases the equipment investment cost and changeover time.

[0003] Patent CN118904976B discloses a low-melting-point alloy filling and straightening device, which can straighten the lead screw while avoiding damage to the spiral groove.

[0004] The aforementioned patent uses the liquid-solid transformation of a low-melting-point alloy to fill the screw spiral groove, turning the screw into a smooth rod, which is then straightened. The entire device has a simple structure and is easy to operate. Once the straightened screw is inserted into the feed inlet, the preparation, straightening, and cleaning processes can be completed under the action of the drive device. However, it cannot adjust the spacing of the straightening device to accommodate different screws of different sizes and models, and there is still room for optimization in terms of adjusting the straightening spacing.

[0005] Therefore, this application proposes a multi-roller straightening device and straightening process for beryllium nickel copper alloy T-shaped profiles that can precisely adjust the width and height between straightening rollers. Summary of the Invention

[0008] Preferably, the outer wall side of the fixed plate is provided with at least five first sliding grooves, and the connecting rods are staggered in different first sliding grooves. The connecting rods are fixed to the fixed plate by nuts on both sides. The rollers include a first roller, a second roller, a third roller and a fourth roller.

[0010] Preferably, a first guide block is provided on the outside of the first fixing hole, and a first scale is provided between the first guide blocks. The outer wall of the moving plate slides against the outer wall of the first guide block. The first guide block is used to constrain the moving plate to move only along the length direction of the first sliding groove, and to provide lateral support and limit to the moving plate perpendicular to the direction of movement when straightening force is applied.

[0011] Preferably, a fixing cylinder is provided on the outer side of the connecting rod, the inner side of the fixing cylinder is in contact with the outer side of the connecting rod, two bearings are provided on the outer side of the fixing cylinder, the outer side of the fixing cylinder is in contact with the inner side of the bearings, and the outer side of the bearings is in contact with the inner side of the rollers.

[0012] Preferably, the outer wall side of the fixing plate is provided with at least three adjustment holes and one receiving groove. The fixing plate is connected to the support plate. The outer wall side of the support plate is provided with a connecting hole. Bolts pass through the connecting hole and the adjustment hole to vertically fix the support plate to the outside of the fixing plate. The outer wall side of the support plate and the inner wall side of the receiving groove are engaged with each other.

[0013] Preferably, the top of the outer wall of the support plate is provided with at least five second sliding grooves, and each second sliding groove is provided with a connecting rod. The connecting rods are staggered in the second sliding grooves. The connecting rods in the second sliding grooves are connected to the third roller and the fourth roller respectively through bearings. The third roller and the fourth roller are located on the left and right sides of the T-shaped profile respectively. The connecting rods move along the second sliding grooves to adjust the left and right clamping distance of the T-shaped profile.

[0014] Preferably, the connecting rod is fixed to the support plate by the outer movable plate. The second sliding groove is symmetrically provided with second fixing holes on both sides. A second guide block is provided on the outer side of the second fixing hole. The outer side of the movable plate slides against the outer side of the second guide block. The second guide block is used to constrain the movable plate to move only along the length direction of the second sliding groove. A second scale is provided between the second guide blocks. The pointing piece on the outer side of the movable plate points to the second scale and is used to convert the left and right displacement of the movable plate into a clamping distance reading.

[0015] Preferably, the fixed plate is provided with a support frame and a discharge plate at its left and right ends, respectively. The support frame is provided with two support rods, which are connected to the fifth rollers through bearings. The two fifth rollers are used to guide and pre-clamp the feed of the T-profile on both sides of the flange, and the T-profile passes through the discharge plate.

[0016] Preferably, the straightening process includes the following steps:

[0017] S1. According to the specifications of the T-profile to be straightened, adjust the upper and lower clamping distance and the left and right clamping distance of the rollers respectively, and align the upper and lower clamping centers with the left and right clamping centers.

[0018] S11. The connecting rod is moved along the first sliding groove by the moving plate. The upper and lower clamping distance between the first roller and the second roller is adjusted to be consistent with the standard height value of the T-profile to be straightened by the cooperation of the pointing plate and the first scale. The moving plate is fixed on the fixed plate by the bolt passing through the third fixed hole and the first fixed hole.

[0019] S12. The connecting rod is moved along the second sliding groove by the moving plate. The left and right clamping distance between the third roller and the fourth roller is adjusted to be consistent with the standard value of the flange width of the T-profile to be straightened by the cooperation of the pointing plate and the second scale. The moving plate is fixed on the support plate by bolts.

[0020] S13. Adjust the vertical installation position of the support plate on the fixed plate through the adjustment hole so that the clamping center line of the third roller and the fourth roller is in the same horizontal plane as the clamping center line of the first roller and the second roller, and fix the support plate on the fixed plate by bolts passing through the connection hole and the adjustment hole.

[0021] S2. After completing the size adjustment, start the drive system to make the T-profile enter each straightening area in sequence for straightening;

[0022] S21. The T-shaped profile first enters between the two fifth rollers on the support frame. The fifth rollers guide and pre-clamp the T-shaped profile on both sides of the flange, guiding the T-shaped profile to the symmetrical center position of the equipment.

[0023] S22. After being pre-clamped, the T-profile enters the vertical straightening area between the first roller and the second roller. Multiple sets of first rollers and second rollers, which are distributed vertically and vertically, alternately apply pressure and release to the upper and lower surfaces of the T-profile, generating alternating bending stress in the height direction to correct the initial bending deformation of the T-profile in the height direction.

[0024] S23. After being straightened from top to bottom, the T-profile enters the left and right straightening area between the third and fourth rollers. Multiple sets of third and fourth rollers, which are staggered from left to right, alternately apply pressure and release to the left and right sides of the T-profile flange, generating alternating bending stress in the width direction to correct the initial bending deformation of the T-profile flange in the width direction. After being straightened from top to bottom and left to right, the T-profile is discharged from the discharge plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention, by incorporating a fixed plate, a first sliding groove, a support plate, a second sliding groove, a connecting rod, and a movable plate, enables adjustment of the roller clamping distance in both the height and width directions. This solves the problem in existing straightening equipment where the rollers are fixed in place, making it impossible to flexibly adjust the clamping distance according to the actual height and flange width of the T-profile to be straightened. This results in poor equipment versatility, requiring multiple sets of equipment or frequent roller assembly replacements for different specifications. The fixed plate of this invention has a first sliding groove, the support plate has a second sliding groove, and the connecting rod moves along the sliding grooves and is fixed by the movable plate. This allows for independent and precise adjustment of the vertical clamping distance between the first and second rollers, as well as the horizontal clamping distance between the third and fourth rollers, according to the specifications of the T-profile. One set of equipment can cover the straightening needs of various T-profile specifications without the need to replace rollers or equip multiple sets of equipment. This improves the equipment's versatility and adaptability, reduces equipment investment costs and factory space requirements, and simplifies and speeds up changeover operations, effectively shortening production changeover time and improving production efficiency.

[0027] 2. This invention, by incorporating a movable plate, a first guide block, and a second guide block, achieves linear guidance and lateral support for the movable plate. This solves the problem of the movable plate lacking effective guidance and lateral support, leading to easy skewing during adjustment and roller displacement under straightening force, affecting adjustment accuracy and straightening quality. In this invention, the first guide block is located on both sides of the first sliding groove, and the second guide block is located on both sides of the second sliding groove. The outer wall of the movable plate slides against the outer wall of the guide block. The guide block not only constrains the movable plate to move only along the length of the sliding groove, ensuring that the movable plate maintains linear motion during adjustment without deflection or tilting, but also provides lateral support and limitation perpendicular to the direction of movement when the roller bears the reaction force of the T-shaped profile during straightening. This prevents lateral displacement or wobbling of the movable plate and connecting rod under straightening reaction force, thus ensuring that the roller remains in the precisely adjusted position during straightening, improving the stability of straightening quality.

[0028] 3. This invention, by incorporating a movable plate, a guide plate, a first scale, and a second scale, enables intuitive reading and precise verification of the roller clamping distance. It transforms distance measurement into scale readings, solving the problems of cumbersome adjustment processes, difficulty in guaranteeing accuracy, and lack of intuitive verification methods when adjusting dimensions, which rely on the operator's visual experience or external measuring tools such as vernier calipers. In this invention, a guide plate is provided on the outer side of the movable plate, with its tip perfectly aligning tangentially with the outermost edge of the roller clamping working surface. Therefore, the scale difference between the two guide plates equals the actual clamping distance between the two corresponding rollers. During adjustment, the operator only needs to observe the corresponding position of the guide plate on the scale to grasp the specific value of the roller distance in real time, achieving precise adjustment without the need for any external measuring tools. This simplifies the operation process, lowers the operational threshold, and allows the operator to quickly verify the correctness of the clamping distance by observing the position of the guide plate after adjustment. This avoids adjustment deviations caused by human reading errors or inaccurate positioning of measuring tools, ensuring adjustment accuracy and changeover efficiency.

[0029] 4. This invention, by incorporating a fixed plate, adjustment holes, a support plate, and connecting holes, achieves precise alignment of the upper and lower clamping centers with the left and right clamping centers, eliminating additional torsional torque during the straightening process. It also solves the problem that after independently adjusting the upper and lower clamping distances and the left and right clamping distances, the center lines of the upper and lower clamping rollers are not on the same horizontal plane, causing the T-profile to be subjected to additional torsional torque and resulting in twisting deformation, severely affecting the straightening quality. In this invention, the outer wall of the fixed plate has at least three adjustment holes evenly arranged vertically, and the support plate is connected by bolts. The support plate is vertically fixed to the fixed plate via the connecting holes and adjustment holes. The operator can select different height adjustment holes according to actual needs to achieve multi-level height adjustment of the support plate on the fixed plate. This ensures that the clamping center lines of the third and fourth rollers are precisely aligned with the clamping center lines of the first and second rollers on the same horizontal plane. At the same time, the engagement between the receiving groove and the support plate ensures that the adjusted support plate will not wobble perpendicular to the plate surface during operation. During the straightening process, the T-profile passes through the upper and lower clamping areas and the left and right clamping areas in a straight line without being subjected to any additional torsional force, thus improving the straightening quality.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6An embodiment of the present invention provides a beryllium nickel copper alloy T-profile multi-roller straightening device. At least five second sliding grooves 10 are provided on the top of the outer wall of the support plate 8. Connecting rods 17 are staggered in the second sliding grooves 10. The connecting rods 17 in the second sliding grooves 10 are connected to the third roller 23 and the fourth roller 24 respectively through bearings 21. The third roller 23 and the fourth roller 24 have the same structure and size. The third roller 23 and the fourth roller 24 are located on the left and right sides of the T-profile respectively. The connecting rods 17 are fixed on the support plate 8 by the outer movable plate 14. The second fixed holes 11 and the second guide blocks 12 are symmetrically arranged on both sides of the second sliding grooves 10. The outer side of the movable plate 14 slides against the outer side of the second guide block 12. A second scale 13 is arranged between the second guide blocks 12. The pointing piece 16 on the outer side of the movable plate 14 points to the second scale 13.

[0043] Furthermore, when the production task is switched from one specification of beryllium nickel copper alloy T-profile to another T-profile with a different flange width, the clamping distance between the third roller 23 and the fourth roller 24 needs to be readjusted to adapt to the flange width of the new T-profile. The support plate 8 is provided with a second sliding groove 10, and each second sliding groove 10 is symmetrically provided with multiple second fixing holes 11 on both sides. The second fixing holes 11 are evenly arranged at a fixed interval along the horizontal direction. In this embodiment, the fixed interval of the second fixing holes 11 is set to 10mm. The 10mm interval is sufficient to cover the adjustment range of the flange width of commonly used beryllium nickel copper alloy T-profiles. From the minimum flange width of 40mm to the maximum flange width of 160mm, it can be adapted by selecting the second fixing holes 11 at different positions.

[0044] A second scale 13 is provided between the second guide blocks 12, and the second scale 13 is arranged along the length of the second guide blocks 12. When making adjustments, the operator directly observes the corresponding position of the guide piece 16 on the outer side of the moving plate 14 on the second scale 13. When adjusting the left and right clamping distance, the operator first determines the standard value of the flange width according to the product drawing or process card of the T-profile to be straightened, and then consults the scale markings on the second scale 13 to find the target scale position corresponding to the standard value of the flange width. The operator uses a wrench to loosen the nuts 18 at both ends of the connecting rod 17 counterclockwise, so that the constraint of the connecting rod 17 in the second sliding groove 10 is released. Then the operator loosens the bolts that pass through the second fixing hole 11 and the third fixing hole 15 on the moving plate 14 counterclockwise. The fixed connection between the movable plate 14 and the support plate 8 is released. At this time, the movable plate 14 and the connecting rod 17 are in a free-moving state. The operator pushes the movable plate 14 horizontally along the direction of the second sliding groove 10. The movable plate 14 drives the connecting rod 17 and the third roller 23 or the fourth roller 24 connected to the connecting rod 17 through the bearing 21 to move synchronously. At the same time, the guide plate 16 on the outer side of the movable plate 14 also slides on the second scale 13 with the movable plate 14. The tangential position of the tip of the guide plate 16 in the horizontal direction is completely coincident with the outermost position of the clamping working surface of the third roller 23 or the fourth roller 24 in the horizontal direction. That is, the horizontal tangential direction of the guide plate 16 coincides with that of the roller. Therefore, the horizontal distance between the two guide plates 16 represents the actual clamping distance between the third roller 23 and the fourth roller 24.

[0045] For example, when it is necessary to adjust the clamping distance between the third roller 23 and the fourth roller 24 to 100mm, the operator pushes the left movable plate 14 so that the left pointer 16 aligns with the 40mm mark on the second scale 13, and at the same time pushes the right movable plate 14 so that the right pointer 16 aligns with the 140mm mark on the second scale 13. The difference between the two pointers 16 is 100mm, and at this time, the clamping distance between the third roller 23 and the fourth roller 24 is exactly 100mm. This converts the measurement of the roller distance into a direct reading of the scale, avoiding the need for the operator to... This method improves adjustment accuracy and changeover efficiency by eliminating errors caused by line-of-sight deviation or inaccurate positioning of measuring tools when using vernier calipers or measuring tapes for direct measurement. It also lowers the technical threshold for operators. After adjustment, the operator tightens the bolts inserted into the second fixing hole 11 and the third fixing hole 15 clockwise to re-fix the moving plate 14 onto the support plate 8. Then, the operator tightens the nuts 18 at both ends of the connecting rod 17 clockwise to securely lock the position of the connecting rod 17 in the second sliding groove 10. This ensures that the rollers will not be displaced due to vibration or force during the straightening process, thus guaranteeing the stability of the straightening quality.

[0046] Please see Figure 2 , Figure 3, Figure 4 , Figure 5 and Figure 7 An embodiment of the present invention provides a beryllium nickel copper alloy T-profile multi-roller straightening device. The second scale 13 is gradually increased along the direction from the left end to the right end of the second guide block 12, and the first scale 5 is gradually increased along the direction from the upper end to the lower end of the first guide block 4. The scale value of the second scale 13 is calibrated proportionally according to the flange width standard of the straightened T-profile, and the scale value of the first scale 5 is calibrated proportionally according to the height standard of the T-profile to be straightened. The second scale 13 is used to verify whether the clamping distance between the third roller 23 and the fourth roller 24 on the left and right sides of the T-profile has been adjusted to the preset standard specification value. The first guide block 4 is provided on the outside of the first fixing hole 3, and the first scale 5 is provided between the first guide blocks 4. The outer wall of the moving plate 14 slides and fits against the outer wall of the first guide block 4.

[0047] Furthermore, the scale values ​​of the second scale 13 gradually increase along the direction from the left end to the right end of the second guide block 12. The scale values ​​are calibrated proportionally according to the flange width standard of the T-profile to be straightened. In this embodiment, the scale values ​​of the second scale 13 are calibrated at a 1:1 ratio, that is, the readings on the second scale 13 directly correspond to the actual size value of the flange width of the T-profile. The starting scale value of the second scale 13 is set to 30mm, the ending scale value is set to 170mm, the interval between adjacent scales is 5mm, a scale line is set every 5mm, and a main scale line with a numerical label is set every 10mm, so that the operation... When adjusting, the operator can quickly and intuitively read the clamping distance value. For example, when the standard value of the flange width of the T-profile to be straightened is 80mm, the operator only needs to move the left and right pointer plates 16 to the position where the difference between the readings on the second scale 13 is equal to 80mm. That is, adjust the pointer plate 16 of the left moving plate 14 to 30mm and the pointer plate 16 of the right moving plate 14 to 110mm. The difference between the readings on both sides is 80mm. At this time, the clamping distance between the third roller 23 and the fourth roller 24 is 80mm, so that no additional conversion or calculation is required in the adjustment process, reducing the difficulty of operation and the probability of error.

[0048] For a T-profile with a flange width of 120mm, the left guide plate 16 is adjusted to 40mm, and the right guide plate 16 is adjusted to 160mm. The difference between the two readings is 120mm. The scale range of the second scale 13 covers the commonly used flange width specifications of beryllium nickel copper alloy T-profiles, which can meet the production needs of different models of products. The scale value of the first scale 5 gradually increases along the direction from the upper end to the lower end of the first guide block 4. The scale value of the first scale 5 is calibrated proportionally according to the height standard of the T-profile to be straightened. The first scale 5 is also calibrated at a 1:1 ratio, with the starting scale value set to 20mm and the ending scale value set to 120mm. The interval between adjacent scales is... 5mm, for example, when the standard height of the T-profile to be straightened is 60mm, the operator adjusts the pointer 16 of the upper moving plate 14 to 40mm on the first scale 5 and adjusts the pointer 16 of the lower moving plate 14 to 100mm on the first scale 5. The difference between the readings on both sides is 60mm. At this time, the clamping distance between the first roller 19 and the second roller 22 is exactly 60mm. For a T-profile with a standard height of 90mm, the upper pointer 16 is adjusted to 20mm and the lower pointer 16 is adjusted to 110mm. The difference between the readings on both sides is 90mm. The scale range of the first scale 5 also covers the commonly used height specifications of beryllium nickel copper alloy T-profiles.

[0049] By calibrating the first scale 5 and the second scale 13 at a 1:1 ratio with a scale interval of 5mm, the first scale 5 and the second scale 13 are visually consistent, reducing the likelihood of confusion for operators when simultaneously adjusting the vertical and horizontal clamps and minimizing the possibility of misoperation. The 5mm scale interval ensures sufficient adjustment accuracy while preventing the scale lines from being too dense and affecting readability. The main scale lines on the scales are all marked with Arabic numerals, facilitating quick location of target scale values ​​by operators. Even after long-term use, with slight wear on the scale surface, operators can still accurately judge the value by the relative positions of adjacent scale lines, improving maintainability and lifespan. Since the second scale 13 and the first scale 5 use the same calibration ratio and scale interval, equipment commissioning personnel and users only need to master one reading method to apply to adjustments in both directions simultaneously, simplifying training content, reducing the skill requirements for personnel, and facilitating widespread application in large-scale production environments.

[0050] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8An embodiment of the present invention provides a beryllium nickel copper alloy T-profile multi-roller straightening device. The outer wall side of the fixed plate 1 is provided with at least five first sliding grooves 2. The connecting rods 17 are staggered in different first sliding grooves 2. The connecting rods 17 are fixed to the fixed plate 1 by nuts 18 on both sides. The rollers include a first roller 19, a second roller 22, a third roller 23 and a fourth roller 24. The connecting rods 17 in the first sliding grooves 2 are connected to the first rollers 19 and the second rollers 22 respectively by bearings 21. The first sliding grooves 2 are symmetrically provided with first fixing holes 3 and first guide blocks 4 on both sides. The top of the outer wall of the moving plate 14 is provided with a third fixing hole 15. The third fixing hole 15 is concentrically aligned with the first fixing hole 3. Bolts pass through the third fixing hole 15 and the first fixing hole 3 to fix the adjusted rollers on the fixed plate 1.

[0051] Furthermore, when the production task is switched to beryllium nickel copper alloy T-profiles with different heights, the clamping distance between the first roller 19 and the second roller 22 needs to be readjusted to adapt to the height dimensions of the new T-profiles. The fixing plate 1 is provided with a first sliding groove 2, and multiple first fixing holes 3 are symmetrically arranged on both sides of the first sliding groove 2. The first fixing holes 3 are evenly arranged at fixed intervals along the vertical direction. In this embodiment, the fixed interval of the first fixing holes 3 is set to 10mm. A first scale 5 is provided between the first sliding grooves 2, and the first scale 5 is arranged along the vertical direction. The upper and lower clamping distance is... During adjustment, the operator first determines the standard height value according to the product specifications of the T-profile to be straightened, and then finds the upper and lower target scale positions corresponding to the height value on the first scale 5. The operator uses a wrench to loosen the nuts 18 set at both ends of the connecting rod 17 counterclockwise, so that the constraint of the connecting rod 17 in the first sliding groove 2 is released. Then the operator loosens the bolts that pass through the first fixing hole 3 and the third fixing hole 15 on the moving plate 14 counterclockwise, so as to release the fixed connection between the moving plate 14 and the fixing plate 1. At this time, the moving plate 14 and the connecting rod 17 are in a free movement state.

[0052] The operator pushes the moving plate 14 vertically along the first sliding groove 2. The moving plate 14 drives the connecting rod 17 and the first roller 19 or the second roller 22 connected to the connecting rod 17 via the bearing 21 to move synchronously. At the same time, the guide plate 16 on the outer side of the moving plate 14 slides on the first scale 5 with the moving plate 14. The tangential position of the tip of the guide plate 16 in the vertical direction is completely coincident with the outermost edge of the clamping working surface of the first roller 19 or the second roller 22 in the vertical direction. That is, the vertical tangential direction of the guide plate 16 coincides with that of the roller. The vertical distance between these two pointing plates 16 represents the actual clamping distance between the first roller 19 and the second roller 22. For example, when the standard height of the T-profile to be straightened is 50mm, the operator pushes the moving plate 14 connected to the first roller 19 upwards, causing the pointing plate 16 of the moving plate 14 to move from its initial position to a position with a reading of 60mm on the first scale 5. At the same time, the operator pushes the moving plate 14 connected to the second roller 22 downwards, causing the pointing plate 16 of the moving plate 14 to move to a position with a reading of 110mm on the first scale 5. The position is such that the difference between the upper and lower readings is 50mm. At this point, the clamping distance between the first roller 19 and the second roller 22 is exactly 50mm. For a T-profile with a standard height of 30mm, the upper guide plate 16 is adjusted to 60mm and the lower guide plate 16 is adjusted to 90mm, with a difference of 30mm between the two readings. After both guide plates 16 reach the target scale position, the operator first tightens the bolts inserted into the first fixing hole 3 and the third fixing hole 15 clockwise, and then re-fixes the moving plate 14 onto the fixing plate 1, so that the moving plate 14 can move. Plate 14 could not continue to move along the first sliding groove 2. Then the operator tightened the nuts 18 at both ends of the connecting rod 17 clockwise to lock the position of the connecting rod 17 in the first sliding groove 2. This ensured that the connecting rod 17 would not move axially due to force during the tightening of the nuts 18, thus avoiding adjustment errors caused by improper operation sequence. After the operation was completed, the upper and lower clamping distance between the first roller 19 and the second roller 22 was set to the required T-profile height value, and the equipment began to straighten the new T-profile specifications.

[0053] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment of the present invention provides a multi-roll straightening device for beryllium nickel copper alloy T-profiles. The outer side of a fixed plate 1 is provided with at least three adjusting holes 6 and one receiving groove 7. The fixed plate 1 is connected to a support plate 8. The outer side of the support plate 8 is provided with connecting holes 9. Bolts pass through the connecting holes 9 and adjusting holes 6 to vertically fix the support plate 8 to the outside of the fixed plate 1. The outer side of the support plate 8 and the inner side of the receiving groove 7 are interlocked.

[0054] Furthermore, after adjusting the vertical and horizontal clamping distances respectively, the vertical positions of the clamping center lines of the first roller 19 and the second roller 22 deviate from the vertical positions of the clamping center lines of the third roller 23 and the fourth roller 24. That is, the centers of the vertical clamping and the centers of the horizontal clamping are not on the same horizontal plane. If the centering deviation is too large, it will cause the T-profile to be subjected to additional torsional torque during the straightening process, causing the T-profile to twist and deform after leaving the straightening area, seriously affecting the straightening quality. (Fixed plate 1 outside) At least three adjustment holes 6 are provided on the side wall. The adjustment holes 6 are evenly arranged in the vertical direction, and the distance between adjacent adjustment holes 6 is 10mm. This distance can provide a sufficient adjustment range to adapt to the height changes of T-shaped profiles of different specifications, while ensuring the strength of the fixing plate 1 in this area. The fixing plate 1 is also provided with a receiving groove 7. The outer side of the support plate 8 and the inner side of the receiving groove 7 are interlocked. After the support plate 8 is installed, it provides a limit in the direction perpendicular to the plate surface of the fixing plate 1 to prevent the support plate 8 from shaking perpendicular to the plate surface during operation.

[0055] When the operator determines that the height of the support plate 8 needs to be adjusted, first use a wrench to loosen the bolts passing through the adjustment hole 6 and the connecting hole 9 on the support plate 8 counterclockwise, thereby releasing the fixed connection between the support plate 8 and the fixed plate 1. Then, the operator moves the support plate 8 vertically along the receiving groove 7, changing the height position of the support plate 8 on the fixed plate 1. During the adjustment process, the operator simultaneously observes the relative positional relationship between the third roller 23 and the fourth roller 24 on the support plate 8 and the first roller 19 and the second roller 22 on the fixed plate 1. When the height is adjusted to the desired level... When the clamping center lines of the third roller 23 and the fourth roller 24 are basically coincident with the clamping center lines of the first roller 19 and the second roller 22, the movement of the support plate 8 is stopped. At this time, the operator aligns the bolts with the adjustment holes 6 on the fixed plate 1 and the connecting holes 9 on the support plate 8, and passes the bolts through the adjustment holes 6 and the connecting holes 9 in sequence. There are at least three adjustment holes 6, and the number and position of the connecting holes 9 correspond to the number and position of the adjustment holes 6. The operator can select different height adjustment holes 6 for fixing according to actual needs, thereby realizing multi-level height adjustment of the support plate 8 on the fixed plate 1.

[0056] After the bolt passes through the adjustment hole 6 and the connection hole 9, the operator tightens the bolt clockwise to re-fix the support plate 8 onto the fixed plate 1. After the height adjustment of the support plate 8 is completed, the clamping centers of the first roller 19 and the second roller 22 are located in the same horizontal plane as the clamping centers of the third roller 23 and the fourth roller 24. During the straightening process, the T-profile will pass through the upper and lower clamping areas and the left and right clamping areas in a straight line without being subjected to additional torsional forces. This ensures that the straightened T-profile has a consistent straightness in the length direction. At the same time, the engagement between the receiving groove 7 and the support plate 8 also ensures the stability of the support plate 8 after the height adjustment is completed. This helps to evenly transfer the reaction force generated during the straightening process to the fixed plate 1, avoids local deformation caused by stress concentration, and improves the overall rigidity and service life of the equipment.

[0057] Please see Figure 1 , Figure 2 and Figure 8 An embodiment of the present invention provides a beryllium nickel copper alloy T-shaped profile multi-roller straightening device. A support frame 26 and a discharge plate 25 are respectively provided at the left and right ends of a fixed plate 1. Two support rods 27 are provided on the support frame 26. The support rods 27 are connected to fifth rollers 28 via bearings 21. The two fifth rollers 28 are used for feeding guidance and pre-clamping of the flanges of the T-shaped profile. The T-shaped profile passes through the discharge plate 25. A fixed cylinder 20 is provided on the outer side of a connecting rod 17. The inner side of the fixed cylinder 20 is in contact with the outer side of the connecting rod 17. Two bearings 21 are provided on the outer side of the fixed cylinder 20. The outer side of the fixed cylinder 20 is in contact with the inner side of the bearings 21, and the outer side of the bearings 21 is in contact with the inner side of the rollers.

[0058] Furthermore, after adjusting the vertical clamping distance, horizontal clamping distance, and the height of the support plate 8, the operator starts the drive system of the straightening equipment. The T-profile first enters the support frame 26 located at the left end of the fixed plate 1. The support frame 26 has two support rods 27, each connected to a fifth roller 28 via a bearing 21. The two fifth rollers 28 are arranged opposite each other, and their surfaces are provided with V-shaped guide grooves. The included angle of the V-shaped guide grooves is 90°, and the opening width matches the maximum width of the T-profile flange. When the T-profile... When the flanges of the profile enter the V-shaped guide grooves of the two fifth rollers 28, the inclined surface of the V-shaped groove forms a line contact with the edge of the flange of the T-profile. During the forward movement of the T-profile, the inclined surface of the V-shaped groove generates a guiding force, which automatically guides the T-profile to the middle symmetrical position of the two fifth rollers 28. This realizes the feeding guidance and pre-clamping function of the T-profile, so that the horizontal position of the T-profile is initially limited before entering the subsequent straightening area, avoiding collision or jamming between the T-profile and the first roller 19 and the second roller 22 due to the deviation of the feeding position.

[0059] After being pre-clamped and guided by the fifth roller 28, the T-profile then enters the straightening area between the first roller 19 and the second roller 22. Both the first roller 19 and the second roller 22 have arc-shaped grooves on their surfaces. The curvature of these grooves matches the curvature of the upper and lower surfaces of the beryllium nickel copper alloy T-profile head. When the T-profile enters between the first roller 19 and the second roller 22, the arc-shaped groove of the upper roller 19 fits tightly against the upper surface of the T-profile head, and the arc-shaped groove of the lower roller 22 fits tightly against the lower surface of the T-profile head. As the T-profile moves forward, the first roller 19... The first roller 19 and the second roller 22 are passively rotated under the action of friction, and at the same time, they apply pressure to the upper and lower surfaces of the T-profile. Since multiple first rollers 19 and second rollers 22 are staggered on the fixed plate 1 along the movement direction of the T-profile, that is, adjacent upper and lower clamping rollers are alternately arranged in the horizontal direction, the upper and lower surfaces of the head of the T-profile are alternately pressed and released when passing through each pair of upper and lower rollers. Through the alternating loading method, alternating bending stress is generated in the height direction of the head of the T-profile, so that the initial bending deformation of the head of the T-profile in the height direction is gradually corrected, and finally the T-profile obtains a consistent straightness in the height direction.

[0060] After being straightened vertically, the T-profile passes through the areas of the first roller 19 and the second roller 22, and then enters the left and right straightening areas where the third roller 23 and the fourth roller 24 are located. Both the third roller 23 and the fourth roller 24 have clamping surfaces. When the T-profile enters between the third roller 23 and the fourth roller 24, the clamping surface of the third roller 23 on the left side is tightly fitted with the left side plane of the T-profile flange, and the clamping surface of the fourth roller 24 on the right side is tightly fitted with the right side plane of the T-profile flange. As the T-profile continues to move forward, the third roller 23 and the fourth roller 24 are passively rotated under the action of friction, simultaneously applying clamping force to the left and right sides of the T-profile flange. Multiple third rollers 23 and fourth rollers 24 are staggered on the support plate 8 along the direction of movement of the T-profile; that is, adjacent left and right clamping rollers are alternately arranged in the horizontal direction. The left and right sides of the T-profile flange are alternately clamped and released as they pass through each pair of left and right rollers, thus applying pressure to the T-profile flange through alternating loading. Alternating bending stress is generated in the width direction, which gradually corrects the initial bending deformation of the T-profile flange in the width direction, and finally makes the T-profile achieve a consistent straightness in the width direction. During the straightening process, since the first roller 19, the second roller 22, the third roller 23 and the fourth roller 24 are all rotatably connected to the connecting rod 17 through the bearing 21, the rollers can rotate synchronously with the movement of the T-profile with extremely low frictional resistance, avoiding sliding friction between the rollers and the surface of the T-profile. This not only protects the surface quality of the beryllium nickel copper alloy T-profile and prevents scratches, but also reduces the wear of the rollers and extends the service life of the equipment. After double straightening in the vertical and horizontal directions, the cross-sectional shape and straightness of the T-profile meet the process requirements. Finally, it is smoothly discharged from the discharge port of the discharge plate 25 set at the right end of the fixed plate 1, completing the entire straightening process. The discharge port size of the discharge plate 25 is larger than the maximum cross-sectional size of the T-profile, ensuring that the T-profile can pass through smoothly without jamming.

[0061] Working principle: When the T-profile multi-roller straightening equipment is working, the operator first adjusts the equipment according to the specifications of the T-profile to be straightened. The operator moves the connecting rod 17 along the first sliding groove 2 or the second sliding groove 10 by moving the moving plate 14, and adjusts the vertical clamping distance between the first roller 19 and the second roller 22 and the horizontal clamping distance between the third roller 23 and the fourth roller 24 by the cooperation of the pointing plate 16 and the first scale 5 or the second scale 13, respectively, to adapt to the height and flange width of the T-profile. At the same time, the operator adjusts the vertical position of the support plate 8 on the fixed plate 1 by adjusting the adjustment hole 6, so that the vertical clamping center and the horizontal clamping center are in the same horizontal plane, avoiding additional torsional torque during the straightening process.

[0062] During the straightening process, the T-profile first enters between the two fifth rollers 28 on the support frame 26. The V-shaped guide grooves on the surface of the fifth rollers 28 guide and pre-clamp the T-profile flanges on both sides, guiding the T-profile to the symmetrical center position of the equipment. Then, the T-profile enters the straightening area between the first roller 19 and the second roller 22. Multiple sets of rollers, arranged vertically and horizontally, alternately apply pressure and release to the upper and lower surfaces of the T-profile, generating alternating bending stress in the height direction, gradually correcting the initial bending deformation of the T-profile in the height direction. Then, the T-profile enters the left and right straightening area where the third roller 23 and the fourth roller 24 are located. Multiple sets of rollers, arranged horizontally and horizontally, alternately apply pressure and release to the flanges on both sides of the T-profile, generating alternating bending stress in the width direction, gradually correcting the bending deformation of the flanges in the width direction. After double straightening from top to bottom and left to right, the cross-sectional shape and straightness of the T-profile meet the process requirements, and it is finally discharged smoothly from the discharge plate 25, completing the entire straightening process.
