Description

TECHNICAL FIELD

[0001] The utility model relates to the related field of titanium alloy pipe straightening device, concretely relates to a straightening device for titanium alloy pipe production. BACKGROUND

[0002] Titanium alloy pipe is a pipe made of titanium alloy, which can be divided into three categories according to the organization. (1 titanium with aluminum and tin elements, 2 titanium with aluminum, chromium, molybdenum and vanadium alloy elements, 3 titanium with aluminum and vanadium elements) They have high mechanical properties, excellent stamping performance, and can be welded in various forms, and the strength of the welded joint can reach 90% of the strength of the base metal, and the cutting processing performance is good. Titanium pipe has high corrosion resistance to chlorides, sulfides and ammonia. The corrosion resistance of titanium in seawater is higher than that of aluminum alloy, stainless steel and nickel-based alloy. In industrial production, unqualified titanium alloy pipes usually need to be straightened by using straightening devices.

[0003] After retrieval, a titanium alloy pipe straightening device of Chinese utility model patent CN222642899U includes a chassis, the chassis is fixedly connected with a support leg on one side, the support leg is fixedly connected with a fixed plate on the side away from the chassis, the fixed plate is fixedly connected with a fixed rod at the top, the fixed rod is rotatably connected with a rotating shaft on one side, and the rotating shaft is fixedly connected with a rotating plate on the outside. In the utility model, the replacement of the straightening clamp is more convenient through the setting of the clamping groove, the first circular hole, the bolt, the nut, the clamping block, the second circular hole, the upper straightening clamp, the lower straightening clamp, the fixed groove and the rubber fixing block. When the upper straightening clamp needs to be installed, the clamping block is inserted into the inside of the clamping groove, then the bolt is inserted into the inside of the first circular hole and the second circular hole, and the nut is screwed on the outside of the bolt to complete the installation of the upper straightening clamp. Then, the lower straightening clamp is installed, the rubber fixing block is aligned with the fixed groove and pressed down to complete the installation of the lower straightening clamp.

[0004] The technical scheme in the application file still has the following problems: the device needs to install multiple straightening clamps, which is relatively cumbersome during replacement and installation, and the position of the straightening clamp is fixed and cannot be moved, resulting in poor flexibility and difficulty in adjusting the position precision between the upper straightening clamp and the two sets of lower straightening clamps, which may cause the titanium alloy pipe to deform due to uneven force and affect the straightening effect. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a straightening device for titanium alloy pipe production to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straightening device for titanium alloy tube production, comprising a base, a placement frame, a limiting frame, a ball nut, and a movable frame. A servo motor is installed in the base, a lead screw is installed at the power shaft end of the servo motor, a ball nut is threaded onto the lead screw, a connecting plate is installed on the ball nut, a movable plate is installed on the connecting plate, a hydraulic rod B is installed on the movable plate, an mounting plate is installed at one end of the hydraulic rod B, a lower straightening mold is installed on the mounting plate, a connecting rod is installed on the ball nut, one end of the connecting rod is connected to the movable frame, a hydraulic rod C is installed on the movable frame, and an upper straightening mold is installed at one end of the hydraulic rod C.

[0007] Using the above technical solution, the titanium alloy tube is placed between the two sets of drive wheels of the placement frame. A servo motor drives the lead screw to rotate in both directions, causing the ball bearing nut threaded onto the lead screw to move linearly left and right along the lead screw. The movement of the ball bearing nut drives the moving plate via the connecting plate, moving the lower straightening mold on the mounting plate below the position where the titanium alloy tube needs straightening. Simultaneously, the connecting rod drives the moving frame to move, moving the upper straightening mold on the moving frame above the position where the titanium alloy tube needs straightening. Then, hydraulic rod B extends, moving the mounting plate and the lower straightening mold upwards to support the bottom of the titanium alloy tube. At the same time, hydraulic rod C also extends... The upper straightening mold moves downward to straighten the titanium alloy tube. Then, by activating the servo motor, the straightening mold is moved to the next position on the titanium alloy tube that needs straightening. This process is repeated until the entire titanium alloy tube is straightened. This eliminates the need for multiple straightening clamps, avoiding significant time wasted during installation and replacement. The flexible movement of the straightening mold improves the usability of the straightening device, ensures the positional accuracy between the upper straightening clamp and the two sets of lower straightening clamps, reduces operational difficulty, and prevents uneven stress on the titanium alloy tube that could cause deformation and affect the straightening effect. This achieves precise straightening of the titanium alloy tube, greatly improving straightening efficiency and accuracy.

[0008] Preferably, a placement frame is installed on the base, and a drive wheel is installed on the placement frame. Two sets of drive wheels are provided, and the drive motor shaft installed on the placement frame is connected to the drive wheel. Two sets of placement frames are provided.

[0009] Using the above technical solution, the placement racks are located on the left and right sides of the base to support and drive the movement of the titanium alloy tube. The two sets of drive wheels are connected by a synchronous belt to ensure the stability and synchronicity of the titanium alloy tube during movement. By controlling its speed and direction, the drive motor can precisely regulate the movement speed and position of the titanium alloy tube, providing accurate positioning for subsequent straightening operations.

[0010] Preferably, a hydraulic rod A is installed on the base, a pressure plate is installed at one end of the hydraulic rod A, a spring column is installed on the pressure plate, a limit frame is installed at one end of the spring column, and two sets of limit wheels are installed on the limit frame.

[0011] Using the above technical solution, hydraulic rod A allows the pressure plate to move up and down, so that the limiting wheel on the limiting frame limits the titanium alloy tube placed on the placement frame. The spring column ensures that the pressure plate can fit tightly against the surface of the titanium alloy tube, improving the stability of the fixation. At the same time, when the two ends of the titanium alloy tube are straightened and tilted, the elasticity of the spring column plays a buffering role, preventing damage to the titanium alloy tube due to excessive pressure.

[0012] Preferably, an auxiliary rod is installed on the mobile frame, and a track is provided on the base, with the auxiliary rod slidably connected to the track.

[0013] The above technical solution allows the moving frame to move smoothly along the base. During the movement of the moving frame, the sliding of the auxiliary rod within the track ensures the straightness and stability of the movement. This improves the operational flexibility of the equipment and also ensures precise position control of the titanium alloy tube during processing. By adjusting the position of the moving frame, straightening operations on different parts of the titanium alloy tube can be easily achieved, improving work efficiency and processing accuracy.

[0014] Preferably, the base has a sliding groove, which is slidably connected to the connecting rod.

[0015] By employing the above technical solution, the cooperation between the slide rail and the connecting rod ensures smooth and unobstructed sliding, thereby improving the overall performance and durability of the equipment. This allows the connecting rod to slide smoothly along the slide rail, further enhancing the stability and flexibility of the equipment.

[0016] Preferably, the lower straightening mold is provided in two sets, and the upper straightening mold is perpendicular to the middle of the two sets of lower straightening molds.

[0017] By adopting the above technical solution, this design enables the upper straightening die to accurately straighten the titanium alloy tube, while the two sets of lower straightening dies provide additional support and straightening effect, ensuring that the titanium alloy tube is evenly stressed during processing and achieves the best straightening effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are: it eliminates the need to install multiple straightening clamps, avoiding a lot of time wasted during replacement and installation; by flexibly moving the position of the straightening mold, it improves the flexibility of the straightening device; it ensures the positional accuracy between the upper straightening clamp and the two sets of lower straightening clamps; it reduces the difficulty of operation; it avoids the problem of uneven stress on the titanium alloy tube causing deformation and affecting the straightening effect; and it achieves precise straightening of the titanium alloy tube, greatly improving straightening efficiency and accuracy.

[0025] Please see Figures 1-4This utility model provides an embodiment of a straightening device for titanium alloy tube production, comprising a base 1, a placement frame 3, a limiting frame 7, a ball nut 11, and a moving frame 17. A servo motor 9 is installed in the base 1. A lead screw 10 is installed at the power shaft end of the servo motor 9. A ball nut 11 is threaded onto the lead screw 10. A connecting plate 21 is installed on the ball nut 11. A moving plate 13 is installed on the connecting plate 21. A hydraulic rod B14 is installed on the moving plate 13. An mounting plate 15 is installed at one end of the hydraulic rod B14. A lower straightening mold 16 is installed on the mounting plate 15. A connecting rod 12 is installed on the ball nut 11. One end of the connecting rod 12 is connected to the moving frame 17. A hydraulic rod C18 is installed on the moving frame 17. An upper straightening mold 19 is installed at one end of the hydraulic rod C18. The titanium alloy tube is placed between the two sets of drive wheels 5 of the placement frame 3. The servo motor 9 drives the lead screw 10 to rotate in both directions, causing the ball nut 11 threaded onto the lead screw 10 to move linearly left and right along the lead screw 10. The movement of the ball nut 11 drives the moving plate 13 via the connecting plate 21, moving the lower straightening mold 16 on the mounting plate 15 below the position where the titanium alloy tube needs straightening. Simultaneously, the connecting rod 12 drives the moving frame 17 to move, moving the upper straightening mold 19 on the moving frame 17 above the position where the titanium alloy tube needs straightening. Then, the hydraulic rod B14 extends, moving the mounting plate 15 and the lower straightening mold 16 upwards to support the bottom of the titanium alloy tube. The pressure rod C18 also extends, causing the upper straightening mold 19 to move downwards to straighten the titanium alloy tube. Then, by starting the servo motor 9, the straightening mold is moved to the next position on the titanium alloy tube that needs straightening. The above operation is repeated until the entire titanium alloy tube is straightened. There is no need to install multiple straightening clamps, avoiding the waste of a lot of time during the replacement and installation process. By flexibly moving the position of the straightening mold, the flexibility of the straightening device is improved, the positional accuracy between the upper straightening clamp and the two sets of lower straightening clamps is ensured, the operation difficulty is reduced, and the problem of uneven force on the titanium alloy tube causing deformation that affects the straightening effect is avoided. Precise straightening of the titanium alloy tube is achieved, which greatly improves the straightening efficiency and accuracy.

[0026] A placement frame 3 is mounted on the base 1, and two sets of drive wheels 5 are mounted on the placement frame 3. The drive motor 4 mounted on the placement frame 3 has its power shaft connected to the drive wheels 5. The placement frame 3 is located on the left and right sides of the base 1, respectively, and is used to support and drive the movement of the titanium alloy tube. The two sets of drive wheels 5 are connected by a synchronous belt to ensure the stability and synchronization of the titanium alloy tube during movement. By controlling its speed and direction, the drive motor 4 can precisely regulate the moving speed and position of the titanium alloy tube, providing accurate positioning for subsequent straightening operations.

[0027] A hydraulic rod A2 is mounted on the base 1. A pressure plate 24 is mounted on one end of the hydraulic rod A2. A spring column 6 is mounted on the pressure plate 24. A limit frame 7 is mounted on one end of the spring column 6. Limit wheels 8 are mounted on the limit frame 7, and two sets of limit wheels 8 are provided. The hydraulic rod A2 allows the pressure plate 24 to move up and down, so that the limit wheels 8 on the limit frame 7 limit the titanium alloy tube placed on the placement rack 3. The spring column 6 ensures that the pressure plate 24 can fit tightly against the surface of the titanium alloy tube, improving the stability of the fixation. At the same time, when the ends of the titanium alloy tube are straightened and tilted, the elasticity of the spring column 6 plays a buffering role, preventing damage to the titanium alloy tube due to excessive pressure.

[0028] An auxiliary rod 22 is mounted on the movable frame 17, and a track 20 is provided on the base 1. The auxiliary rod 22 is slidably connected to the track 20. This allows the movable frame 17 to move smoothly along the base 1. During the movement of the movable frame 17, the sliding of the auxiliary rod 22 within the track 20 ensures the straightness and stability of the movement. This improves the operational flexibility of the equipment and also ensures precise position control of the titanium alloy tube during processing. By adjusting the position of the movable frame 17, straightening operations on different parts of the titanium alloy tube can be easily achieved, improving work efficiency and processing accuracy.

[0029] The base 1 has a sliding groove 23, which is slidably connected to the connecting rod 12. The cooperation between the sliding groove 23 and the connecting rod 12 ensures smooth and unobstructed sliding, thereby improving the overall performance and durability of the equipment. This allows the connecting rod 12 to slide smoothly along the sliding groove 23, further enhancing the stability and flexibility of the equipment.

[0030] Two sets of lower straightening dies 16 are provided, and the upper straightening die 19 is perpendicular to the middle of the two sets of lower straightening dies 16. This design allows the upper straightening die 19 to accurately straighten the titanium alloy tube, while the two sets of lower straightening dies 16 provide additional support and straightening effect, ensuring that the titanium alloy tube is evenly stressed during processing and achieves the best straightening effect.

[0031] The control modules and electronic components involved in this application are all existing mature technologies, with many products on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional use. The scope of protection of this application does not involve improvements to the control software and methods, so the models of electronic components and the control flow of the control system will not be described in detail here. A circuit controller is installed on the motor, allowing the motor to flexibly adjust the rotation direction and rotation angle according to actual operating requirements, significantly improving the operational flexibility and safety performance of the equipment. The brake mechanism reliably locks the position when the motor stops, preventing accidental displacement caused by inertia and ensuring the stability and safety of the device in the stopped state.

[0032] Working principle: The titanium alloy tube is placed between the two sets of drive wheels 5 of the placement frame 3. Then, the hydraulic rod A2 is activated to move the pressure plate 24 downward, so that the limit wheel 8 on the limit frame 7 limits the titanium alloy tube placed on the placement frame 3. The spring column 6 ensures that the pressure plate 24 can fit tightly against the surface of the titanium alloy tube, improving the stability of the fixation. At the same time, when the two ends of the titanium alloy tube are straightened and tilted, the elasticity of the spring column 6 plays a buffering role to prevent damage to the titanium alloy tube due to excessive pressure. Then, the servo motor 9 is activated to drive the lead screw 10 to rotate forward and backward. This causes the ball nut 11, threaded onto the lead screw 10, to move linearly left and right along the lead screw 10. The movement of the ball nut 11 drives the moving plate 13 via the connecting plate 21, moving the lower straightening mold 16 on the mounting plate 15 below the position where the titanium alloy tube needs straightening. Simultaneously, the connecting rod 12 drives the moving frame 17 to move, moving the upper straightening mold 19 on the moving frame 17 above the position where the titanium alloy tube needs straightening. Then, the hydraulic rod B14 extends, causing the mounting plate 15 and the lower straightening mold 16 to move upwards. The bottom of the titanium alloy tube is supported, and the hydraulic rod C18 extends, driving the upper straightening mold 19 downward to straighten the titanium alloy tube. The upper straightening mold 19 is perpendicular to the middle of the two sets of lower straightening molds 16, ensuring that the titanium alloy tube is evenly stressed during processing and achieving the best straightening effect. By starting the drive motor 4 in conjunction with the synchronous belt between the two sets of drive wheels 5, the two sets of drive wheels 5 are rotated, which can control the moving speed and position of the titanium alloy tube. Then, by starting the servo motor 9, the straightening mold is moved to the next position of the titanium alloy tube that needs to be straightened. The above operation is repeated until the entire titanium alloy tube is straightened. There is no need to install multiple straightening clamps, avoiding a lot of time wasted during replacement and installation. By flexibly moving the position of the straightening mold, the flexibility of the straightening device is improved, the positional accuracy between the upper straightening clamp and the two sets of lower straightening clamps is guaranteed, the operation difficulty is reduced, and the problem of uneven stress on the titanium alloy tube causing deformation and affecting the straightening effect is avoided. Precise straightening of the titanium alloy tube is achieved, greatly improving the straightening efficiency and accuracy.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
