After preparation, the equipment begins processing the metal tube. Finally, a servo motor drives the processing device to bend the metal tube. However, when correcting the metal tube, in addition to clamping it, it is also necessary to flip it to achieve comprehensive correction. The aforementioned device only clamps the metal tube; when different positions of the metal tube need correction, the operator must flip it, which reduces the efficiency of the correction process.

[0009] Also includes:

[0010] The connecting frame is provided with a flip-clamping assembly on one side surface near the bottom;

[0013] Preferably, a connecting plate is fixedly connected to one side surface of the drive motor output end through the connecting frame, a groove is formed on the side surface of the connecting plate away from the drive motor, and a servo motor is fixedly installed on the top surface of the connecting plate.

[0014] Preferably, the output end of the servo motor is fixedly connected to a double-ended lead screw through one side surface of the connecting plate, the bottom surface of the double-ended lead screw is rotatably connected to the groove, and threaded sleeves are threaded on both sides of the surface of the double-ended lead screw.

[0018] Preferably, a plurality of damping blocks are fixedly installed in the middle of the top surface of the placement plate, a damping spring is fixedly connected to the top surface of the damping block, and a receiving plate is fixedly connected to the top surface of the damping spring.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This correction device for processing irregularly shaped metal tubes, by setting a flipping clamping assembly, allows the metal tube to be clamped and flipped simultaneously, thereby satisfying the need for comprehensive correction of the metal tube and improving the correction efficiency. Simultaneously, by setting damping blocks, damping springs, and a receiving plate, the wear and tear on various components of the equipment is reduced, thereby extending the service life of the equipment and reducing maintenance and replacement costs. The specific details are as follows:

[0020] 1. By setting up a flip-grip assembly, when it is necessary to clamp a metal tube, the metal tube is placed on the clamping plate located below. Then, the servo motors on both sides are activated simultaneously, causing the output ends of the servo motors to drive the rotation of the double-ended lead screw. The rotation of the double-ended lead screw drives the movement of the threaded sleeve. At the same time, one side of the threaded sleeve is fixedly connected to the connecting rod, and the connecting rod is connected to the groove. Through the cooperation between the connecting rod and the groove, the threaded sleeve can be limited, thereby allowing the threaded sleeve to move. When the threaded sleeves on both sides move to the middle position of the double-ended lead screw, the clamping plate below drives the metal tube... The metal tube rises, causing its upper part to come into contact with the clamping plate located above, thus clamping the metal tube. When it is necessary to flip the metal tube, the drive motor is activated, causing the output end of the drive motor to drive the connecting plate to rotate. This, in turn, causes the clamping plate to rotate, which in turn causes the metal tube to rotate. Simultaneously, the rotation of the metal tube also causes the other side of the flipping clamping assembly to rotate. This allows for both clamping and flipping of the metal tube, enabling comprehensive correction of the metal tube and improving the correction efficiency.

[0021] 2. By setting up an electric push rod, a placement plate, a damping block, a damping spring, and a receiving plate, after the metal tube is clamped by the flip-clamping assembly, the electric push rod is activated via the control terminal. The output end of the electric push rod drives the placement plate to rise. The rise of the placement plate drives the receiving plate to rise as well, allowing the receiving plate to fit against the bottom of the metal tube. As the electric push rod drives the placement plate to continue rising, the interaction force between the receiving plate and the metal tube is transmitted to the damping spring, causing the damping spring to deform. The damping spring can be adjusted according to different elastic forces to reduce the swaying of the metal tube when the correction device corrects it. The cooperation between the damping block, damping spring, and receiving plate provides support for the metal tube and also buffers pressure, evenly distributing the pressure of the support points on the surface of the metal tube and reducing the possibility of surface damage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a correction device for processing irregularly shaped metal tubes, including a workbench 1, a connecting frame 2 fixedly installed on the top surface of the workbench 1; stabilizing plates 3 symmetrically installed on the bottom surface of the connecting frame 2, a linear guide rail 4 fixedly installed in the middle of one side surface of the stabilizing plate 3, a sliding sleeve 5 penetrating the surface of the linear guide rail 4, a cylinder 6 fixedly installed in the middle of the bottom surface of the sliding sleeve 5, a correction device 7 provided on the bottom surface of the cylinder 6, and electric push rods 8 symmetrically installed inside the workbench 1, with a placement plate 9 fixedly connected to the top surface of the electric push rods 8; it also includes: a flipping clamping assembly 10 provided on one side surface of the connecting frame 2 near the bottom; wherein, the flipping clamping assembly 10 includes a support plate 1001 fixedly connected to the connecting frame 2; wherein, a drive motor 1002 is fixedly installed on the top surface of the support plate 1001, such as Figure 1-5 As shown, by setting the flip clamping assembly 10, the metal tube can be clamped and flipped at the same time, thereby satisfying the need for comprehensive correction of the metal tube and improving the correction efficiency. At the same time, by setting the damping block 15, damping spring 16 and receiving plate 17, the wear of various parts of the equipment is reduced, thereby extending the service life of the equipment and reducing the maintenance and replacement costs. The linear guide rail 4 is model BGXH358E, the electric push rod 8 is model LAM33-A, and the correction device 7 is existing technology and has the same working principle as existing technology.

[0030] A connecting plate 1003 is fixedly connected to one side surface of the connecting frame 2 through the output end of the drive motor 1002. A groove 1004 is formed on the side surface of the connecting plate 1003 away from the drive motor 1002. A servo motor 1005 is fixedly installed on the top surface of the connecting plate 1003. A double-ended lead screw 1006 is fixedly connected to the output end of the servo motor 1005 through the side surface of the connecting plate 1003. The bottom surface of the double-ended lead screw 1006 is rotatably connected to the groove 1004. Threaded sleeves 1007 are threaded on both sides of the surface. A connecting rod 1008 is fixedly connected to one side of the threaded sleeve 1007. A clamping plate 1009 is fixedly connected to the side of the connecting rod 1008 away from the threaded sleeve 1007. The connecting rod 1008 is connected through the groove 1004. An extension plate 11 is fixedly connected to the other side of the connecting frame 2 near the bottom. A fixing block 12 is fixedly connected to one side of the top surface of the extension plate 11. A rotating rod 13 is rotatably connected to the middle of one side surface of the fixing block 12. Figure 2 , 4 As shown, by simultaneously activating the servo motors 1005 on both sides, the output ends of the servo motors 1005 drive the rotation of the double-ended lead screw 1006. The rotation of the double-ended lead screw 1006 causes the threaded sleeve 1007 to move. Simultaneously, one side of the threaded sleeve 1007 is fixedly connected to the connecting rod 1008, which is connected through the groove 1004. The cooperation between the connecting rod 1008 and the groove 1004 limits the movement of the threaded sleeve 1007. When the threaded sleeves 1007 on both sides move towards the middle position of the double-ended lead screw 1006, the clamping plate 1009 below causes the metal tube to rise, thus bringing the upper part of the metal tube into contact with the clamping plate 1009 above, thereby completing the movement. The device clamps a pair of metal tubes. When it is necessary to flip the metal tubes, the drive motor 1002 is activated, causing the output end of the drive motor 1002 to drive the connecting plate 1003 to rotate. This, in turn, causes the clamping plate 1009 to rotate, which in turn causes the metal tubes to rotate. Simultaneously, the rotation of the metal tubes also causes the other side of the flipping clamping assembly 10 to rotate. This allows for both clamping and flipping of the metal tubes, enabling comprehensive correction of the metal tubes and improving the correction efficiency. Furthermore, the clamping plate 1009 is made of rubber, which increases the friction between the clamping plate 1009 and the metal tubes, reducing the likelihood of the metal tubes falling off during rotation.

[0031] The workbench 1 has symmetrically arranged placement slots 14 inside, which are fixedly connected to the electric push rod 8. Several damping blocks 15 are fixedly installed in the middle of the top surface of the placement plate 9. Damping springs 16 are fixedly connected to the top surface of each damping block 15, and receiving plates 17 are fixedly connected to the top surface of each damping spring 16. Figure 5 As shown, the electric push rod 8 is activated by the control terminal, causing the output end of the electric push rod 8 to drive the placement plate 9 to rise. The rise of the placement plate 9 drives the support plate 17 to rise, so that the support plate 17 fits against the bottom of the metal tube. As the electric push rod 8 drives the placement plate 9 to continue rising, the interaction force between the support plate 17 and the metal tube is transmitted to the damping spring 16, causing the damping spring 16 to deform. The damping spring 16 can be selected with different elastic forces according to the actual situation, thereby reducing the shaking of the metal tube when the correction device 7 corrects the metal tube. Thus, the cooperation between the damping block 15, the damping spring 16 and the support plate 17 can provide support for the metal tube and also buffer the pressure, evenly distributing the pressure of the support point on the surface of the metal tube and reducing the possibility of surface damage. At the same time, the support plate 17 is made of polytetrafluoroethylene (PTFE), which has low friction and a buffering function, reducing the friction between it and the metal tube. This ensures that the metal tube will not be significantly obstructed when it is flipped.

[0032] Working principle: Before using this type of correction device for processing irregularly shaped metal tubes, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, firstly, by setting up the flip-clamping assembly 10, when it is necessary to clamp the metal tube, the metal tube is placed on the clamping plate 1009 located below. Then, the servo motors 1005 on both sides are started at the same time, so that the output end of the servo motor 1005 drives the double-ended lead screw 1006 to rotate. The rotation of the double-ended lead screw 1006 can drive the threaded sleeve 1007 to move. At the same time, one side of the threaded sleeve 1007 is fixedly connected to the connecting rod 1008. The connecting rod 1008 is connected through the groove 1004. Through the cooperation between the connecting rod 1008 and the groove 1004, the threaded sleeve 1007 can be limited, so that the threaded sleeve 1007 can move. The threaded sleeve 1007 on both sides moves towards the middle position of the double-ended lead screw 1006. During movement, the lower clamping plate 1009 causes the metal tube to rise, bringing the top of the metal tube into contact with the upper clamping plate 1009, thus clamping the metal tube. Simultaneously, when the metal tube needs to be flipped, the drive motor 1002 is activated, causing its output to rotate the connecting plate 1003. This, in turn, causes the clamping plate 1009 to rotate, which in turn rotates the metal tube. The rotation of the metal tube also rotates the flipping clamping assembly 10 on the other side. This allows for both clamping and flipping of the metal tube, enabling comprehensive alignment of the metal tube and improving alignment efficiency.

[0033] Secondly, by setting up an electric push rod 8, a placement plate 9, a damping block 15, a damping spring 16, and a receiving plate 17, after the metal tube is clamped by the flip-clamping assembly 10, the electric push rod 8 is activated through the control end, causing the output end of the electric push rod 8 to drive the placement plate 9 to rise. The rise of the placement plate 9 drives the receiving plate 17 to rise, so that the receiving plate 17 fits against the bottom of the metal tube. At the same time, as the electric push rod 8 drives the placement plate 9 to continue to rise, the interaction force between the receiving plate 17 and the metal tube is transmitted to the damping spring 16, causing the damping spring 16 to deform. The damping spring 16 can be selected with different elastic forces according to the actual situation, so as to reduce the shaking of the metal tube when the correction device 7 corrects the metal tube. Thus, the cooperation between the damping block 15, the damping spring 16, and the receiving plate 17 can provide support for the metal tube and also buffer the pressure, evenly distributing the pressure of the support point on the surface of the metal tube and reducing the possibility of surface damage.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
