Description

Technical Field

[0001] This invention belongs to the technical field of straightening equipment, specifically relating to a CNC straightening machine and a straightening method for steel pipes. Background Technology

[0002] With the rapid development of generative artificial intelligence technology, global computing power demand is growing exponentially. Traditional air-cooling technology has reached its physical limits in terms of heat dissipation efficiency and energy consumption. Liquid cooling technology, especially cold plate liquid cooling, has become a key solution to address the risk of thermal runaway in high-power chips due to its advantages of large specific heat capacity and high heat dissipation efficiency. The industry generally believes that liquid cooling technology is rapidly moving from "niche pilot projects" to "mainstream standard," becoming a necessity for scenarios such as high-density data centers and AI computing clusters.

[0003] Stainless steel pipes, used as transport pipelines for liquid cooling plates, require high dimensional accuracy. Since most products are manufactured using welding, finished products often exhibit bending deformation. To eliminate bending deformation during production, it is necessary to develop a CNC straightening machine specifically designed for product straightening to meet production demands.

[0004] The current straightening methods for products primarily involve manual feeding, centering, and adjustment of the pressure roller. This requires manually placing shims and adjusting the straightening points, making straightening accuracy highly dependent on operator experience and prone to over-straightening, under-straightening, and surface scratches. Dimensions must be measured simultaneously during straightening, resulting in low efficiency and requiring highly skilled personnel; skill transfer can easily lead to process instability. Furthermore, existing equipment lacks online monitoring and closed-loop control, cannot adapt to different materials and specifications, and can only be used for sample straightening. Its stability and efficiency during mass production cannot meet current production demands.

[0005] Therefore, there is an urgent need to propose a new technical solution to address the above problems. Summary of the Invention

[0026] The technical solution of this application will be described in detail below with reference to specific embodiments.

[0027] Please see Figure 1 and 2A CNC straightening machine includes a frame 1, a floating support mechanism 2, a mounting frame 3, a transverse drive mechanism 4, and a straightening mechanism 5. A first track 11 is mounted on the frame 1 along the X-direction. The floating support mechanism 2 is slidably connected to the first track 11 and supports the steel pipe to be straightened. The mounting frame 3 is fixedly connected to the frame 1. The transverse drive mechanism 4 is mounted on the top of the mounting frame 3. The straightening mechanism 5 is connected to the output end of the transverse drive mechanism 4. A support station 21 is provided on the top of the floating support mechanism 2. The transverse drive mechanism 4 is connected to the straightening mechanism 5 so that the straightening mechanism 5 can move to the support station 21. The transverse drive mechanism 4 drives the straightening mechanism 5 to move laterally to the support station 21, and the straightening mechanism 5 applies a straightening force to the steel pipe on the support station 21. Under the drive of the transverse drive mechanism 4, the straightening mechanism 5 can move laterally in the horizontal direction above the support station 21, thereby straightening different positions of the steel pipe.

[0028] In some embodiments, see Figure 1 The transverse drive mechanism 4 includes a first bracket 41, a mounting base 42, a mounting plate 43, a drive motor 44, and a transmission rack 45. The first bracket 41 is connected to the mounting frame 3 and is arranged along the X direction. The bottom of the first bracket 41 is provided with at least one first guide rail 411, which is also arranged along the X direction. The top of the mounting base 42 is slidably connected to the first guide rail 411. The bottom of the mounting plate 43 is fixedly connected to the mounting base 42. The drive motor 44 is fixedly connected to the top of the mounting plate 43. The transmission rack 45 is connected to the outside of the first bracket 41 and is arranged along the X direction. The output end of the drive motor 44 is provided with a gear 441, which meshes with the transmission rack 45. The straightening mechanism 5 is connected to the mounting base 42. The drive motor 44 drives the gear 441 to rotate, and the gear 441 meshes with the transmission rack 45 to drive the mounting base 42 to slide laterally along the first guide rail 411, thereby driving the straightening mechanism 5 to move laterally to the support station 21; wherein, the drive motor 44 is a servo motor.

[0029] In some embodiments, please refer to Figure 3 The straightening mechanism 5 includes a servo cylinder 51, a pressure sensor 52, and an extrusion member 53. The servo cylinder 51 is fixedly connected to the mounting base 42, which has a through hole 421. The output end of the servo cylinder 51 passes through the through hole 421. The pressure sensor 52 and the extrusion member 53 are sequentially arranged at the output end of the servo cylinder 51, with the pressure sensor 52 located between the output end of the servo cylinder 51 and the extrusion member 53. The servo cylinder 51, pressure sensor 52, and extrusion member 53 are arranged sequentially along the direction toward the support station 21. The servo cylinder 51 is used to drive the extrusion member 53 to reciprocate along the Z direction, so that the extrusion member 53 can descend or rise, thereby realizing the extrusion of the steel pipe by the extrusion member 53 and changing the position of the extrusion point.

[0030] In some embodiments, please refer to Figure 5 The extruder 53 has a positioning hole 531. A connecting block 532 and an extrusion block 533 are sequentially arranged at the bottom of the extruder 53. One end of the connecting block 532 is connected to the bottom of the extruder 53, and the other end of the connecting block 532 is connected to the extrusion block 533. The output end of the servo cylinder 51 has a connecting post 511, which passes through the middle of the pressure sensor 52 and extends into the positioning hole 531 on the extruder 53. The top of the pressure sensor 52 abuts against the output end of the servo cylinder 51, and the bottom of the pressure sensor 52 abuts against the top of the extruder 53. When the servo cylinder 51 drives the extruder 53 to press down, the pressure sensor 52 detects the straightening pressure in real time and feeds the pressure signal back to the main control module 6. The main control module 6 adjusts the driving force of the servo cylinder 51 in real time according to the pressure signal, thereby achieving closed-loop control of the straightening force.

[0031] In some embodiments, please refer to Figure 5 The projected area of ​​the extrusion block 533 along the axial direction of the servo cylinder 51 is larger than the projected area of ​​the connecting block 532 along the axial direction of the servo cylinder 51. This structure can increase the effective working area between the extrusion block 533 and the steel pipe. Under the same straightening pressure, the pressure can be more evenly distributed on the surface of the steel pipe, avoiding excessive pressure per unit area that could cause indentations or damage to the surface of the steel pipe, thus improving the straightening quality.

[0032] In some embodiments, please refer to Figure 2 The transverse drive mechanism 4 also includes a second bracket 46, which is arranged along the X direction. The first bracket 41 and the second bracket 46 are arranged parallel to each other. The second bracket 46 is fixedly connected to the mounting bracket 3. A working area 47 is formed between the first bracket 41 and the second bracket 46. The servo cylinder 51 is located in the working area 47. The servo cylinder 51 moves in the working area 47, which can improve its operating stability. The bottom of the second bracket 46 is provided with at least one second guide rail 461, which is arranged along the X direction. The second guide rail 461 and the first guide rail 411 are arranged parallel to each other. The top of the mounting base 42 is slidably connected to the second guide rail 461.

[0033] In some embodiments, please refer to Figure 4 There are two of each of the first guide rail 411 and the second guide rail 461. By setting multiple first guide rails 411 and second guide rails 461, the sliding stability of the mounting base 42 can be improved.

[0034] In some embodiments, please refer to Figure 3The floating support mechanism 2 includes multiple support components 22, which are arranged sequentially along the length of the first track 11, specifically along the X-direction. Each support component 22 includes a mounting member 221 and a support member 222. The bottom of the mounting member 221 is slidably connected to the first track 11, and the support member 222 is fixedly connected to the top of the mounting member 221. The top of the support member 222 has a placement groove 2221. The placement groove 2221 is a V-shaped groove or an arc-shaped groove, used to accommodate and support the steel pipe. The floating support mechanism 2 can slide along the first track 11 to adjust the support position and adapt to steel pipes of different lengths and degrees of curvature.

[0035] In some embodiments, please refer to Figure 3 The first track 11 includes a first slide rail 111 and a second slide rail 112. Both the first slide rail 111 and the second slide rail 112 are arranged sequentially along the X direction and are parallel to each other. A first slider 2211 and a second slider 2212 are mounted on the bottom of the mounting component 221. The bottom of the first slider 2211 is slidably connected to the first slide rail 111, and the bottom of the second slider 2212 is slidably connected to the second slide rail 112. By setting the first slider 2211, the sliding connection between the mounting component 221 and the first slide rail 111 can be enhanced; by setting the second slider 2212, the sliding connection between the mounting component 221 and the second slide rail 112 can be enhanced.

[0036] In some embodiments, a first guide block 422 and a second guide block 423 are mounted on the top of the mounting base 42. The first guide block 422 is slidably connected to the first guide rail 411, and the second guide block 423 is slidably connected to the second guide rail 461. By setting the first guide block 422, the sliding connection effect between the mounting base 42 and the first guide rail 411 can be enhanced. By setting the second guide block 423, the sliding connection effect between the mounting base 42 and the second guide rail 461 can be enhanced.

[0037] In some embodiments, the straightening machine further includes a main control module 6 and a display control module 7. The transverse drive mechanism 4, pressure sensor 52, straightening mechanism 5, and display control module 7 are electrically connected to the main control module 6.

[0038] In some embodiments, the straightening machine further includes a vision scanning module 8, which is electrically connected to the main control module 6. The vision scanning module 8 is used to identify the workpiece that needs to be straightened, obtain workpiece parameters, and feed the workpiece parameters back to the main control module 6. The workpiece parameters include the length, shape, interference points, and deformation of the workpiece. In other embodiments, the vision scanning module 8 is a vision scanner.

[0039] In some embodiments, the straightening machine further includes a data port, which is electrically connected to the main control module 6 and is used to export straightening data.

[0040] In some embodiments, the drive motor 44, servo cylinder 51, pressure sensor 52, and display control module 7 are electrically connected to the main control module 6.

[0041] In some embodiments, the main control module 6 is a PLC controller or an industrial computer.

[0042] In some embodiments, the display control module 7 is a touch screen.

[0043] In some embodiments, the straightening machine further includes an electrical box 9, and the drive motor 44, servo cylinder 51, pressure sensor 52, main control module 6, and display control module 7 are electrically connected to the electrical box 9. The electrical box 9 is used to supply power to the drive motor 44, servo cylinder 51, pressure sensor 52, main control module 6, and display control module 7.

[0044] In some embodiments, the main control module 6, the display control module 7, and the electrical box 9 are arranged adjacent to each other on the outside of the frame 1.

[0045] Please see Figure 7 , Figure 7 This application discloses a method for straightening a steel pipe, which includes the following steps: S1: The visual recognition module 8 identifies the workpiece parameters of the workpiece to be straightened, and adjusts the position of the support component 22 of the floating support mechanism 2 according to the workpiece parameters; it identifies parameters such as the length, shape, interference point and deformation of the steel pipe, and adjusts the floating support mechanism 2 to slide along the first track 11 to the corresponding position according to the workpiece parameters. S2: The display control module 7 controls the main control module 6 to perform zeroing operation on the drive motor 44 and the servo cylinder 51, and sets the position of the pre-straightening point in the length direction of the workpiece according to the workpiece parameters. The pre-straightening point includes at least the first straightening preset point and the second straightening preset point. The zeroing operation ensures that the initial position of the drive motor 44 and the servo cylinder 51 is accurate. S3: Puts the straightening machine into manual mode; S4: Move the servo electric cylinder 51 to the first straightening preset point and obtain the first initial pressure; the first initial pressure can be a system preset value or a manually input value. S5: Control the servo cylinder 51 to drive the extruder 53 to press down until the first initial pressure is reached; during the pressing process of the extruder 53, the extrusion block 533 contacts the surface of the steel pipe, the pressure sensor 52 detects the straightening force in real time, and feeds the straightening force back to the main control module 6; S6: Control the servo cylinder 51 to lift the extruder 53, and control the drive motor 44 to move the servo cylinder 51 to the second straightening preset point to obtain the second initial pressure. The second initial pressure can be a system preset value or a manually input value. S7: Control the servo cylinder 51 to drive the extruder 53 to press down until the second initial pressure is reached; S8: Inspect the straightened workpiece. If it meets the standard, save the straightening data and put the straightening machine into automatic mode according to the straightening data. Otherwise, adjust the first initial pressure and the second initial pressure according to the inspection results, return to the step of moving the servo cylinder 51 to the first straightening preset point, and repeat the straightening and inspection.

[0046] It should be noted that the first and second initial pressures need to be selected according to the corresponding workpiece structure. Those skilled in the art can select the corresponding values ​​according to the actual situation, and no specific limitations are made here.

[0047] In some embodiments, when entering automatic mode, the main control module 6 of the straightening machine automatically controls the drive motor 44 and the servo cylinder 51 according to the saved straightening data, repeatedly executing the straightening operation of moving the servo cylinder 51 to the first straightening preset point and pressing down, lifting it up, and moving it to the second straightening preset point and pressing down. Through this method, the straightening parameters are continuously optimized, realizing the switching from manual mode to automatic mode, effectively improving the efficiency and consistency of steel pipe straightening.

[0048] In some embodiments, when the straightening machine enters automatic mode, steps S4 to S7 are repeated based on the straightening data.

[0049] In some embodiments, after adjusting the first initial pressure and the second initial pressure, the process returns to step S3 described above.

[0050] This invention features precise servo control, requiring the drive equipment to shift from hydraulic control to fully automatic servo control to achieve high-precision straightening. It enables precise setting of straightening position, straightening height, and dimensional control. The process is complex; modern manufacturing demands that the straightening machine not only address bending but also consider material stress characteristics. Servo control technology eliminates the rebound of residual internal stress, ensuring the liquid-cooled tube maintains dimensional stability during subsequent machining or long-term operation. The equipment is also digitally intelligent; the straightening machine's data port can output data for archiving, enabling real-time monitoring of correction force and straightening data, outputting straightening reports, and connecting to a dedicated system for process monitoring.

[0051] This invention consists of three parts: a frame 1, an electrical control system, and a straightening system. The frame 1 is prestressed and welded to improve overall rigidity. The electrical control system includes a PLC controller, a drive motor 44, a pressure sensor 52, a touch screen, a floating support mechanism 2, a slide rail, the frame 1, and an electrical box 9. It can automatically control the position and pressure of the straightening point and can also output reports via USB flash drive or network. The straightening system is operated by a high-precision servo electric cylinder 51. A centering mechanism (not shown in the figure) can be equipped on the floating support mechanism to ensure that the product can always be kept in the center of the straightening station, thereby achieving point-to-point pressure straightening of the product. The straightening force is automatically adjusted by the pressure sensor 52, and corresponding straightening parameters can be stored for different products.

[0052] The control principle of this invention is as follows: Identify the workpiece requiring straightening, adjust the position of the floating support mechanism 2 via the slide rail to form effective support, first use the touch screen to control the PLC controller to zero the drive motor 44 and servo cylinder 51, and set the length direction position of the pre-straightening point (X direction is the length direction, assuming 2 straightening points). Move the servo cylinder 51 to the first straightening preset point, set the initial pressure, and use the manual mode of the equipment. Use the touch screen to control the servo cylinder 51 to drive the extruder 53 to press down, straightening the position of the first straightening preset point, and observe the pressure change on the touch screen until the preset initial pressure is reached. Raise the servo cylinder 51 and move it to the second straightening preset point, and use the same method to control the servo cylinder 51 to drive the extruder 53 to straighten the position of the second straightening preset point. Inspect the straightened product to see if it meets the standard. If it does not meet the standard, the pressing pressure needs to be fine-tuned. After the product meets the requirements, save the data and start the automatic mode to realize the automatic straightening of the product.

[0053] This invention includes a frame 1, a straightening mechanism 5, a hydraulic servo system, and an electrical control system. The frame 1 is a prestressed rigid frame. The straightening mechanism 5 is equipped with hydraulic pressing and an adjustable roller system. The electrical control system achieves closed-loop adaptive control of straightening parameters based on detection signals. Automated control and fixed-point straightening are achieved through the linkage of the drive motor 44, the servo cylinder 51, and the PLC controller. Multiple bottom support blocks are connected to slide rails, allowing for manual adjustment of the required positions, providing more flexible support points, making it more suitable for non-standard product operations, and covering most products requiring straightening. The equipment chassis is equipped with external ports, enabling connection to the user's dedicated system and exporting straightening data. The straightening mechanism 5 can sense the pressing force, and the main control module 6 adjusts the pressing height of the servo cylinder 51 reasonably based on pressure changes.
