Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1 to 10 As shown, a straightening machine angle adjustment device includes an angle driving device 2 and an angle straightening device 30. The angle driving device 2 is installed at the bottom of the straightening base 31; the angle straightening plate 32 is rotatably installed on the top of the straightening base 31 and is also connected to the angle driving device 2; the angle straightening device 30 is fixed on the angle straightening plate 32; the angle driving device 2 is used to drive the angle straightening device 30 to rotate through the angle straightening plate 32 to adjust the angle between the angle straightening device 30 and the movable straightening device 20.

[0017] The angle straightening device 30 and the movable straightening device 20 are located on opposite sides of the fixed straightening device 10, with both devices on the same side, forming a triangle. One side of the workpiece rests against the straightening roller 12 of the fixed straightening device 10, while the other side rests against the straightening rollers 12 of the movable straightening device 20 and the angle straightening device 30. When the workpiece has a large curvature, to improve straightening efficiency, the angle straightening device 30 can be used to adjust the angle between itself and the movable straightening device 20 during straightening, thus reversing the straightening of the workpiece and quickly straightening it, improving its straightness. This even allows straightening of workpieces with near-circular curvature, solving the problem of existing three-point straightening equipment being unable to directly straighten workpieces with excessively large curvature angles or those approaching circular shapes. Furthermore, reversing the straightening angle during straightening improves efficiency and reduces the number of reciprocating straightening operations.

[0018] Specifically, the angle driving device 2 includes an angle fixing seat 21, a first angle rotating seat 23, an angle adjusting screw 25, an angle screw nut 26, a second angle rotating seat 27, an angle adjusting seat 28, and an angle rotation motor 22. The angle fixing seat 21 is installed at the bottom of one end of the straightening seat 31. The first angle rotating seat 23 is rotatably installed inside the angle fixing seat 21 and is rotatably connected to the angle adjusting screw 25 through a bearing seat. The angle adjusting screw 25 is connected to the angle screw nut 26, which is fixed on the second angle rotating seat 27. The second angle rotating seat 27 is rotatably installed on the angle adjusting seat 28, which is fixed to the bottom of the angle straightening plate 32. The angle rotation motor 22 is located on the angle fixing seat 21 and is connected to the angle adjusting screw 25. By adjusting the angle of the angle straightening device 30 through the angle rotation motor 22 and the screw pair, both the accuracy of the rotation angle and the reliable clamping force can be guaranteed.

[0019] For ease of assembly, the first angle rotating seat 23 has symmetrically arranged first rotating shafts 231 at both ends, and the first rotating shafts 231 are rotatably mounted on the angle fixing seat 21; the second angle rotating seat 27 has symmetrically arranged second rotating shafts 271 at both ends, and the second rotating shafts 271 are rotatably mounted on the angle adjusting seat 28. Furthermore, to improve the flexibility of rotation of the first angle rotating seat 23 and the second angle rotating seat 27, the angle driving device 2 also includes a first rotating sleeve 24 and a second rotating sleeve 29. The first rotating sleeve 24 is fixed on the angle fixing seat 21 and rotatably connected to the first rotating shaft 231; the second rotating sleeve 29 is fixed on the angle adjusting seat 28 and rotatably connected to the second rotating shaft 271.

[0020] To accommodate different workpieces and achieve a wider angle range for straightening, the straightening machine's angle adjustment device also includes an angle position adjustment device. This device is connected to both the angle straightening plate 32 and the angle straightening device 30, and is used to adjust the position of the angle straightening device 30. Specifically, the angle position adjustment device includes an angle adjustment slider 42, an angle adjustment plate 44, an angle adjustment screw 43, and an angle adjustment handle 45. The angle adjustment slider 42 is located at the bottom of the angle straightening device 30. The slider 42 is a dovetail block, and it slides within the angle adjustment groove 41 of the angle straightening plate 32. The angle adjustment groove 41 is also a dovetail groove. Angle adjustment plate 44 is fixed to one end of angle adjustment slide 41 and is rotatably connected to one end of angle adjustment screw 43 via bearing. Angle adjustment screw 43 is also connected to angle adjustment slider 42 via thread, which is used to drive angle adjustment slider 42 to move, thereby realizing the adjustment of the distance between angle straightening device 30 and fixed pressing device 10. Angle adjustment handle 45 fixes the end of angle adjustment screw 43, making it convenient to rotate angle adjustment screw 43.

[0021] The angle straightening device 30, the movable straightening device 20 and the fixed straightening device 10 have the same structure and are used to straighten the workpiece by means of the straightening roller 12.

[0022] The angle straightening device 30 includes a straightening base 11, a straightening slider 13, a straightening roller 12, a straightening cylinder 14, a locking cylinder 17, and a locking block 18. The straightening base 11 has a guide hole 111 along its length, which is a through hole. A locking hole 113 is located on the top of the straightening base 11, communicating with and perpendicular to the guide hole 111. The straightening slider 13 is slidably inserted into the guide hole 111. A locking groove 131 is provided on the side of the straightening slider 13. Both ends of the straightening slider 13 are connected to the piston rods of the straightening roller 12 and the locking cylinder 17, respectively. The straightening roller 12 is rotatably connected to the end of the straightening slider 13, allowing it to rotate freely. The straightening roller 12 is located at one end of the straightening base 11. The straightening cylinder 14 is fixed to the other end of the straightening base 11. The locking cylinder 17 is fixed on the top of the straightening base 11 and located above the locking hole 113. The piston rod of the locking cylinder 17 is connected to the locking block 18. The locking block 18 is movably inserted into the locking hole 113 and is opposite to the locking groove 131. When it is necessary to lock the position of the straightening slider 13 so that the position of the straightening roller 12 remains unchanged for final straightening, the locking cylinder 17 drives the locking block 18 to insert into the locking groove 131, so that the position of the straightening slider 13 remains unchanged, and thus the position of the straightening roller 12 remains unchanged.

[0023] Angle adjustment slider 42 is located at the bottom of the straightening base 11.

[0024] During initial straightening, the workpiece is straightened by the pressure of the cylinder. After repeated straightening, when the straightness of the workpiece is high, a larger pressure is required. Since the position of the straightening roller cannot be changed, the position of the straightening roller 12 is locked by the locking block 18, so that the pressure adjustment cylinder 14 is ineffective.

[0025] The use of a straightening cylinder 14 allows the straightening roller 12 to have greater freedom during the initial straightening of the workpiece, and requires less pressure, making the initial straightening of the workpiece easier. Because the initial deformation of the workpiece is large, the required straightening pressure is small. At this time, by repeatedly rolling with a small straightening pressure, the straightness of the workpiece after final straightening is high. At the same time, it solves the problem that the straightening machine requires a large straightening pressure, reduces the requirements for the overall strength of the straightening machine, reduces equipment costs, and does not affect the straightening efficiency.

[0026] When performing the final straightening, since the deformation angle of the workpiece is very small, a large pressure is required. Therefore, the position of the straightening roller 12 is limited by the locking block 18 and the locking groove 131, eliminating the need for the cylinder to provide the final straightening pressure. This reduces the requirements for the cylinder and allows the use of a smaller cylinder, thus reducing the cost of the cylinder.

[0027] The straightening achieved by using the straightening cylinder 14 to provide constant pressure is the same as the gradual straightening achieved by the motor and ball screw, and the time required is also basically solved, but it can greatly reduce the cost of the equipment and the cost of use.

[0028] To limit the position of the straightening roller 12 and prevent it from rotating axially, the guide hole 111 is a square hole and the straightening slider 13 is a square block. The square hole and the square straightening slider 13 prevent the straightening roller from rotating axially, and also solve the problems of easy mode and low pressure bearing capacity caused by the groove structure set along the length direction of the straightening slider 13 by pin engagement.

[0029] To facilitate the insertion of the locking block 18 into the locking groove 131, the locking groove 131 is a V-shaped groove, and the end of the locking block 18 is tapered and matches the locking groove 131.

[0030] To facilitate observation of the position of the straightening roller 12, the angle straightening device 30 also includes a scale mark 132, which is set on the straightening slider 13 and is positioned opposite to the end of the straightening base 11.

[0031] To facilitate adjusting the position of the straightening roller 12 according to different workpieces—for example, workpieces of different diameters require different positions when locking the straightening roller 12, meaning the distance between the straightening rollers 12 on both sides of the workpiece must match the outer diameter of the workpiece—the angle straightening device 30 also includes a connecting slider 15 and a straightening rod 16. The connecting slider 15 is movably inserted into the guide hole 111. One end of the connecting slider 15 is connected to the straightening cylinder 14, and the other end is connected to one end of the straightening rod 16. The other end of the straightening rod 16 is connected to the straightening slider 13, thus adjusting the position of the straightening roller 12. Furthermore, the straightening rod 16 has a connecting screw 161 and a connecting block 163 at both ends, and a connecting screw hole 151 at one end of the connecting slider 15. The connecting screw 161 and the connecting screw hole 151 are connected by threads to adjust the distance between the connecting slider 15 and the straightening slider 13. The diameter of the connecting block 163 at the end of the straightening link 16 is larger than the diameter of the straightening link 16, forming a T-shaped structure. The connecting block 163 is movably inserted into the rotating groove 135 at the end of the straightening slider 13. The rotating groove 135 is a T-shaped groove.

[0032] To facilitate direct adjustment of the straightening connecting rod 16, the straightening base 11 is provided with an adjustment groove 122 communicating with the guide hole 111. The adjustment groove 122 is also positioned opposite to the straightening connecting rod 16. The straightening connecting rod 16 is provided with a tool groove 162, which can be engaged with an open-end wrench to achieve rotation of the straightening connecting rod 16. The tool groove 162 is positioned opposite to the adjustment groove 122. The adjustment groove 122 allows the straightening connecting rod 16 to be adjusted without disassembling the straightening cylinder 14, improving efficiency.

[0033] To facilitate the fixing of the locking cylinder 17, the angle straightening device 30 also includes a locking connecting seat 19. The locking connecting seat 19 is fixed to the top of the straightening base 11 and connected to the locking cylinder 17. The locking connecting seat 19 has a through hole inside to facilitate the installation and movement of the locking block 18. Furthermore, to facilitate the observation of the state of the locking block 18, the locking connecting seat 19 is also provided with several locking observation slots 191 for observing the locking block 18.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
