Abstract

This invention relates to the field of titanium tube production technology, and provides a fixed-length segmentation device and its working method for titanium tube production. The device includes a worktable, a segmentation assembly mounted on top of the worktable for segmenting titanium tubes, a support assembly mounted below the segmentation assembly for supporting the segmentation points of the titanium tubes, and a fixed-length assembly. The fixed-length assembly includes a bracket, a guide rail mounted on top of the bracket, and a detection mechanism sliding on the guide rail. This device solves the problem that defects such as end-face tilting at the end of the titanium tube after previous cutting, caused by the characteristics of titanium material, easily affect the fixed-length data error. By setting multiple baffles, the device divides the end of the titanium tube into multiple independent detection areas.

Description

Technical Field

[0001] This invention relates to the field of titanium tube production technology, and more specifically, to a fixed-length segmentation device for titanium tube production and its working method. Background Technology

[0002] Titanium tubes, as a special type of tubing with excellent properties such as high strength, corrosion resistance, and low density, are used in manufacturing fields such as aerospace, marine engineering, medical devices, and chemical equipment. During the production process, because titanium tubes are continuous tubular, they need to be segmented into fixed lengths to facilitate subsequent welding, assembly, and other processes.

[0003] Currently, the titanium tube is transported horizontally by a conveying mechanism to a fixed length segment. When the front end of the titanium tube reaches the cutting station, it continues to be transported forward until its end is tightly pressed against the fixed length block at a pre-set position. At this time, the conveying system stops running, and then the cutting blade feeds vertically downward to complete the sawing action, thereby realizing the fixed length segmentation of the titanium tube.

[0004] However, in actual production, due to titanium's low melting point, high chemical activity, and poor thermal conductivity, the pre-cutting process is prone to defects such as end face tilting, molten and adhered debris, and burrs. This results in the presence of adhered blocky debris or irregular protrusions formed by melting and solidification at the end of the titanium tube. When the defective end of the titanium tube touches the length block, the conveying system will stop immediately upon detecting the contact signal. However, at this time, the actual effective length of the titanium tube has not reached the preset standard, and the final cut titanium tube will have a significant error in the length data, affecting the product qualification rate. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a fixed-length segmentation device for titanium tube production and its working method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixed-length segmentation device for titanium tube production, comprising a workbench.

[0007] The segmentation assembly is mounted on top of the workbench and is used for segmenting titanium tubes.

[0008] A support component is installed below the segmentation component and is used to support the segmentation points of the titanium tube.

[0009] A length-fixing assembly, disposed on one side of the worktable and used for assisting in length-fixing the end of a titanium tube, includes a bracket, a guide rail mounted on the top of the bracket, and a detection mechanism sliding on the guide rail. The detection mechanism includes a slide block sliding on the guide rail and a fixed seat mounted on one side of the slide block. Multiple hinge rods are hinged to one side of the fixed seat, and baffles are connected to the ends of the multiple hinge rods. A spring rod is installed in the middle of the fixed seat near the slide block, and one end of the spring rod passes through the fixed seat and is connected to a micro switch. Multiple auxiliary rods are hinged to the micro switch, and the auxiliary rods are hinged to the side walls of the corresponding hinge rods. A micro switch is installed at each hinge point of the fixed seat.

[0010] Multiple baffles work together to make zoned contact with the end of the titanium tube, and are simultaneously detected by multiple sets of microswitches. When all sets of microswitches are triggered, a fixed length can be achieved.

[0011] The present invention is further configured such that: the support component includes a bidirectional electric slide rail mounted on the top of the workbench and located below the segmented component; a positioning mechanism is mounted on the top of the bidirectional electric slide rail and two sliding platforms are slidably mounted thereon; an auxiliary mechanism is mounted on the top of each sliding platform; the positioning mechanism is located between the two auxiliary mechanisms; an industrial camera is mounted on the side wall of the segmented component; the industrial camera is arranged opposite to the positioning mechanism and is used to detect the bending degree of the titanium tube between the two auxiliary mechanisms.

[0012] The present invention is further configured such that: both sets of auxiliary mechanisms include a carrier mounted on the top of the corresponding slide table, a collar is provided on one side of the top of the carrier, a limit rod is connected to the side of the collar near the carrier, and the end of the limit rod passes through the carrier.

[0013] The present invention is further configured such that: a clamping cylinder is vertically mounted on the side wall of the collar, a pressure block is connected to the piston rod end of the clamping cylinder, a buffer seat is mounted on the bottom of the carrier, and the buffer seat and the corresponding pressure block are staggered.

[0014] The present invention is further configured such that: the positioning mechanism includes a positioning seat mounted on the top of the bidirectional electric slide rail and a positioning groove disposed on the top of the positioning seat, the width of the positioning groove being greater than the thickness of the cutting disc, two through holes being formed in the side wall of the positioning groove, and a laser sensor being installed inside the positioning seat, the laser sensor being used to detect the cutting depth of the cutting disc.

[0015] The invention is further configured such that: a telescopic cylinder is vertically mounted on one side of the connecting seat, and a baffle is connected to the top of the piston rod of the telescopic cylinder, the baffle being used to shield the industrial camera.

[0016] The invention is further configured such that: an electric wheel and a pipe pressing assembly are installed on the top of the workbench, one end of the pipe pressing assembly extends above the electric wheel; a V-shaped frame is installed on the top of the workbench and between the electric wheel and the segmentation assembly; a positioning wheel is installed on the top of the workbench and is located between the V-shaped frame and the segmentation assembly; a pneumatic lifting platform and a belt drive mechanism are installed inside the workbench; the belt drive mechanism is installed on the top of the pneumatic lifting platform; and a drive wheel is connected to the output end of the belt drive mechanism, with the drive wheel located directly below the positioning wheel.

[0017] The present invention is further configured such that: the pressure tube assembly includes a vertical frame mounted on the top of the workbench, a horizontal frame hinged to the top of the vertical frame, and an adjusting cylinder hinged to the top of the workbench, wherein the output end of the adjusting cylinder is hinged to one end of the horizontal frame, and a wheel is rotatably mounted on the other end of the horizontal frame, the wheel being located above the electric wheel.

[0018] The present invention is further configured such that: the segmented assembly includes a connecting seat mounted on the top of the workbench, a hinge seat is hinged to the top of the connecting seat, a hinge cylinder is hinged to the top of the connecting seat, the piston rod end of the hinge cylinder is hinged to one end of the hinge seat, a motor is mounted on one side of the hinge seat, and a cutting blade is connected to the output end of the motor.

[0019] A method for fixed-length segmentation in titanium tube production, using a fixed-length segmentation device for titanium tube production as described above, includes the following steps: S1. Insert the titanium tube into the interior of the support assembly and extend it to the top of the fixed-length assembly. During the extension process, use four baffles to block the end of the titanium tube. S2. During the blocking process, if the end of the titanium tube is uneven, the four baffles will be pushed to different degrees. After blocking, the baffles will drive the hinge rod to swing, and the hinge rod will drive the auxiliary rod to swing synchronously, causing the micro switch to horizontally displace and the spring rod to retract. When all four baffles trigger the corresponding micro switch, the titanium tube will be in place at the fixed length.

[0020] S3. After the titanium tube is fixed in length, the titanium tube stops being transported. Then, the support component limits the segmentation position of the titanium tube. The segmentation component is used to segment the titanium tube. After the segmentation is completed, the titanium tube at the rear end continues to be transported forward, thereby pushing the segmented titanium tube out of the support component and dropping it. The titanium tube at the rear end continues to be fixed in length and limited by the length-fixing component and the support component, and can be segmented again by the segmentation component.

[0021] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting multiple baffles, the end of the titanium tube is divided into multiple independent detection areas. Only when all the baffles in all areas are pushed and the corresponding micro switches are triggered can the fixed length be determined to be in place. This filters out false triggering signals caused by local defects and improves the accuracy of fixed length segmentation of titanium tube and the product qualification rate.

[0022] (2) By using the coarse limit of the support components and the real-time detection of the bending degree of the industrial camera, the pressure block and the buffer seat work together to correct the bending degree and bending direction of the titanium tube before cutting, and concentrate the correction force on the position of maximum bending deformation. The stress is dispersed by the rigid support below to avoid reverse bending or local plastic deformation, and ensure that the axis of the titanium tube is perpendicular to the plane of the cutting plate during cutting, thereby improving the fixed length accuracy and the perpendicularity of the cutting surface.

[0023] (3) The positioning groove provides a safe feeding space for the cutting blade, and the laser sensor detects the cutting position in real time, thereby controlling the timing of the synchronous separation of the two sets of auxiliary mechanisms for clamping titanium tubes. This allows the cut titanium tube end face to disengage from the cutting blade while under pressure, avoiding the rigid impact of the titanium tube's elastic rebound on the cutting blade, reducing tool wear and extending service life, and preventing burrs, chipping, and dimensional deviations at the cut, thus ensuring the end face quality and length consistency of the titanium tube segmented products.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0038] Please see Figures 1-11 The present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 2 A fixed-length segmentation device for titanium tube production includes a workbench 1. An electric wheel 3 and a tube pressing assembly 5 are mounted on the top of the workbench 1. One end of the tube pressing assembly 5 extends above the electric wheel 3. The electric wheel 3 supports the titanium tube and, in conjunction with the tube pressing assembly 5, synchronously drives the titanium tube to rotate axially. The specific structure of the tube pressing assembly 5 is as follows: See Figure 2 and Figure 3The pressing tube assembly 5 includes a vertical frame 51 mounted on the top of the workbench 1, a horizontal frame 52 hinged to the top of the vertical frame 51, and an adjusting cylinder 53 hinged to the top of the workbench 1. The output end of the adjusting cylinder 53 is hinged to one end of the horizontal frame 52. The other end of the horizontal frame 52 has a rotating wheel 54. The wheel 54 is located above the electric wheel 3. The adjusting cylinder 53 drives one end of the horizontal frame 52 to move down, causing the horizontal frame 52 to drive the wheel 54 to move down. When the titanium tube is placed on the electric wheel 3, the wheel 54 presses on the titanium tube. Through the rotation of the electric wheel 3 and the limiting position of the wheel 54, the titanium tube rotates axially, which facilitates subsequent rapid segmentation cutting.

[0039] See Figures 1-4 A segmentation assembly 2 is installed on the top of the workbench 1. A V-shaped frame 4 is installed on the top of the workbench 1 and between the electric wheel 3 and the segmentation assembly 2. The segmentation assembly 2 is used to segment the titanium tube, while the V-shaped frame 4 is used to support the titanium tube in the segmented state.

[0040] See Figures 1-4 A positioning wheel 6 is installed on the top of the workbench 1, located between the V-shaped frame 4 and the segmented assembly 2. A pneumatic lifting platform and a belt drive mechanism 91 are installed inside the workbench 1. The belt drive mechanism 91 is mounted on top of the pneumatic lifting platform, and its output end is connected to a drive wheel 9, located directly below the positioning wheel 6. The pneumatic lifting platform consists of a lifting cylinder and a lifting platform. The lifting cylinder drives the lifting platform to move in the height direction, thereby driving the belt drive mechanism 91 and the drive wheel 9 to move up and down. The belt drive mechanism 91 consists of a servo motor and a driven belt. The system consists of a wheel, a drive pulley, and a synchronous transmission belt. A servo motor drives the drive pulley to rotate, which in turn drives the synchronous transmission belt. At this time, the two pulleys rotate synchronously. The drive wheel 9 is connected to the driven pulley. When the driven pulley rotates, it drives the drive wheel 9 to rotate. When the titanium tube needs to be transported, the drive wheel 9 moves up and presses the titanium tube under the positioning wheel 6. At this time, the rotation of the drive wheel 9 causes the titanium tube to be transported forward. When the fixed length is reached, the drive wheel 9 stops rotating and descends away from the titanium tube. The titanium tube falls on the electric wheel 3 and the V-shaped frame 4. At this time, the segmentation assembly 2 cuts the titanium tube into segments.

[0041] See Figure 4 The specific structure of segmented component 2 is as follows: The segmented assembly 2 includes a connecting seat 21 mounted on the top of the workbench 1. A hinge seat 23 is hinged to the top of the connecting seat 21, and a hinge cylinder 22 is hinged to the top of the connecting seat 21. The piston rod end of the hinge cylinder 22 is hinged to one end of the hinge seat 23. A motor 24 is mounted on one side of the hinge seat 23, and a cutting blade 25 is connected to the output end of the motor 24. The hinge cylinder 22 drives the hinge seat 23 to rotate around the hinge point of the connecting seat 21 through the extension and retraction of the piston rod, thereby realizing the feed movement of the cutting blade 25 in the height direction. The motor 24 drives the cutting blade 25 to rotate at high speed, generating cutting force to cut the titanium tube.

[0042] See Figure 1 and Figure 5 A length-fixing component 8 is installed on one side of the workbench 1. The length-fixing component 8 is used to assist in length-fixing the titanium tube. That is, during the conveying process, the length-fixing component 8 blocks the titanium tube, and the titanium tube is at a fixed length. The cutting point is below the cutting blade 25. At this time, the length-fixing segment is completed by cutting with the cutting blade 25. The length-fixing component 8 includes a bracket 81, a guide rail 82 installed on the top of the bracket 81, and a detection mechanism 83 sliding on the guide rail 82. The detection mechanism 83 slides on the guide rail 82 to adjust the length-fixing distance of the titanium tube. The detection mechanism 83 blocks the titanium tube. The detection mechanism 83 includes a slide block 831 sliding on the guide rail 82. The slide block 831 is used to block the end of the titanium tube. After the titanium tube is blocked, the titanium tube stops forward conveying and rotates axially. Then, in conjunction with the cutting action of the cutting blade 25, the length-fixing segment is completed.

[0043] However, in actual production, due to titanium's low melting point, high chemical activity, and poor thermal conductivity, the pre-cutting process is prone to defects such as end face tilting, molten and adhered debris, and burrs. This results in the presence of adhered blocky debris or irregular protrusions formed by melting and solidification at the end of the titanium tube. When the defective end of the titanium tube touches the length block, the conveying system will stop immediately upon detecting the contact signal. However, at this time, the actual effective length of the titanium tube has not reached the preset standard, and the final cut titanium tube will have a significant error in the length data, affecting the product qualification rate.

[0044] See Figures 5-7 To this end, a fixed seat 832 is installed on one side of the slide 831. Multiple hinge rods 833 are hinged to one side of the fixed seat 832, and baffles 834 are connected to the ends of the hinge rods 833. A spring rod 837 is installed in the middle of the fixed seat 832 near the slide 831. One end of the spring rod 837 passes through the fixed seat 832 and is connected to a micro switch 836. Multiple auxiliary rods 835 are hinged to the micro switch 836, and the auxiliary rods 835 are hinged to the side walls of the corresponding hinge rods 833. A micro switch 836 is installed at each hinge point of the fixed seat 832. Multiple baffles 834 divide the end of the titanium tube into multiple independent detection areas, each corresponding to an independent micro switch 836. When the titanium tube moves to the position of the detection mechanism 83, the multiple baffles 834 block the end of the titanium tube. If the end of the titanium tube is uneven during the blocking process, the four baffles 834 will be pushed to different degrees. After blocking, the baffles 834 drive the hinge rod 833 to swing. The hinge rod 833 synchronously drives the auxiliary rod 835 to swing, causing the micro switch 836 to horizontally displace and the spring rod 837 to retract. When all four baffles 834 trigger the corresponding micro switch 836, the titanium tube reaches the fixed length.

[0045] Only when all the baffles 834 in all areas are pushed by the end of the titanium tube and trigger the corresponding micro switch 836, is it determined that the end of the titanium tube is in contact with the length-fixing component 8, and the effective length of the titanium tube reaches the set value. This can effectively filter out false triggering signals caused by local defects and improve the length-fixing accuracy.

[0046] In Example 2, although the length is determined by the length-fixing component 8, the titanium tube may be bent as a whole or at its ends during the transportation process. In this case, when the titanium tube is segmented, the cutting surface may be offset, which will affect the length-fixing accuracy.

[0047] In the traditional method, in order to improve the accuracy of fixed length, two limiting stations are set at the segmented cutting position. The titanium tube is restricted when it is inserted, and the cut surface can remain vertical during cutting. However, in this case, one limiting station will be forcibly squeezed and pressed against the titanium tube, while the other limiting station will not be in contact with the titanium tube. In this case, the titanium tube is still in a bent state, and the segmented cutting surface will still tilt and shift.

[0048] See Figure 1 and Figure 8 To this end, a support component 7 is installed on top of the workbench 1 and below the segmentation component 2. The support component 7 is used to support the segmentation points of the titanium tube, that is, to perform coarse positioning, bending detection, bending correction and cutting support for the titanium tube. It can locate and correct the shape of the segmentation points of the titanium tube before cutting, ensuring that the axis of the titanium tube is perpendicular to the plane of the cutting blade 25 during cutting, thus solving the problem of cutting surface offset caused by the bending of the titanium tube.

[0049] See Figure 8 and Figure 9 The specific structure of support component 7 is as follows: The support assembly 7 includes a bidirectional electric slide rail 71 mounted on the top of the workbench 1 and located below the segmented assembly 2. The top of the bidirectional electric slide rail 71 is equipped with a positioning mechanism 73 and has two sliding tables 72. The bidirectional electric slide rail 71 is a stepper motor linear slide rail sliding seat module, that is, the lead screw in the linear slide rail is driven to rotate by the stepper motor, causing the sliding seat to slide along the linear slide rail. The lead screw is a bidirectional lead screw, and a sliding seat is threaded to each of the two threads on the bidirectional lead screw. When the bidirectional lead screw rotates, the two sliding seats can move closer or further away from each other synchronously. A sliding table 72 is connected to each of the two sliding seats. In order to maintain the normal operation of the bidirectional electric slide rail 71, the bidirectional electric slide rail 71 is set downward to reduce the damage of the precision parts of the bidirectional electric slide rail 71 to the debris during titanium tube cutting.

[0050] See Figure 9 and Figure 11 Each slide 72 is equipped with an auxiliary mechanism 74 on its top. A positioning mechanism 73 is located between two auxiliary mechanisms 74. The auxiliary mechanisms 74 move closer to each other or further away from each other via a bidirectional electric slide rail 71. When the two sets of auxiliary mechanisms 74 move closer to each other, they can perform coarse positioning, bending correction and cutting support on the titanium tube. An industrial camera 103 is installed on the side wall of the connecting seat 21. The industrial camera 103 is set opposite to the positioning mechanism 73 and is used to detect the bending degree of the titanium tube between the two auxiliary mechanisms 74.

[0051] Specifically, the bidirectional electric slide rail 71 can adjust the distance between the two auxiliary mechanisms 74 to adapt to different cutting length requirements. The industrial camera 103 captures the outline image of the titanium tube between the two auxiliary mechanisms 74. The industrial camera 103 is connected to the external control system. The industrial camera 103 transmits the captured data to the analysis system to determine the curvature and bending direction of the titanium tube, and transmits the detection results to the control system to provide data support for subsequent bending correction.

[0052] See Figure 9 and Figure 11 Both sets of auxiliary mechanisms 74 include a carrier 741 mounted on the top of the corresponding slide table 72. A collar 744 is provided on one side of the top of the carrier 741. A limit rod 743 is connected to the side of the collar 744 near the carrier 741. The end of the limit rod 743 passes through the carrier 741. A through hole is opened on the side wall of the carrier 741. The diameter of the through hole is larger than the diameter of the titanium tube. When the titanium tube is transported, the two sets of auxiliary mechanisms 74 approach and fit together. The end of the titanium tube passes through the through hole on the carrier 741 of the two sets of auxiliary mechanisms 74 and the collar 744, thus restricting the titanium tube. Then the two sets of auxiliary mechanisms 74 separate from each other and retain a certain cutting gap. The collar 744 first performs coarse limiting on the titanium tube and initially corrects the large curvature of the titanium tube. Then the titanium tube is driven to rotate by the electric wheel 3. The industrial camera 103 detects the bending direction in real time. When the highest point of the bend rotates to the top, the rotation stops.

[0053] See Figure 9 and Figure 11 A clamping cylinder 745 is vertically mounted on the side wall of the collar 744. A pressure block 747 is connected to the piston rod end of the clamping cylinder 745. A buffer seat 746 is mounted on the bottom of the carrier 741. The buffer seat 746 and the corresponding pressure block 747 are staggered. When the industrial camera 103 detects that the highest point of the titanium tube bending has rotated to the top and stops the titanium tube from rotating, the clamping cylinder 745 drives the pressure block 747 to move downward, directly applying the concentrated correction force to the position of maximum bending deformation of the titanium tube, forcing the bent part to return to straightness. At the same time, the buffer seat 746 provides rigid support from directly below the titanium tube, dispersing the correction stress by pressing from above and below, avoiding reverse bending or local plastic deformation of the titanium tube due to excessive force at a single point. After correction, the axis at the segment point of the titanium tube can remain horizontal and form a perpendicular relationship with the cutting plane of the cutting blade 25, eliminating the problem of cutting surface tilting and offset caused by the bending of the titanium tube, and improving the length accuracy of the titanium tube segment and the perpendicularity of the cutting surface.

[0054] Furthermore, in order to cut the titanium tube, a gap must be reserved between the two sets of auxiliary mechanisms 74 to accommodate the cutting blade 25 and chip removal. At this time, the two ends of the cutting point are clamped, the middle cutting point is squeezed into a rigid state, and because the sleeve is forcibly positioned, springback and rigid wear of the cutting blade 25 will occur at the moment of cutting, causing the fracture to deviate.

[0055] See Figure 9 and Figure 10 The positioning mechanism 73 includes a positioning seat 731 mounted on the top of the bidirectional electric slide rail 71 and a positioning groove 732 set on the top of the positioning seat 731. The width of the positioning groove 732 is greater than the thickness of the cutting blade 25. The positioning groove 732 provides feeding space for the cutting blade 25 and prevents the cutting blade 25 from having a hard collision with the positioning seat 731 after cutting into place. Two through holes 733 are opened on the side wall of the positioning groove 732. A laser sensor 734 is installed inside the positioning seat 731. The laser sensor 734 forms a detection optical path through the two through holes 733 to penetrate the positioning groove 732. When the cutting blade 25 completely cuts the titanium tube and just enters the positioning groove 732, it will instantly block the laser beam path. The laser sensor 734 immediately sends a cutting completion signal to the external control system. After receiving the signal, the control system immediately controls the bidirectional electric slide rail 71 to rotate in the opposite direction, so that the two sets of auxiliary mechanisms 74 can simultaneously and quickly separate to both sides while maintaining the clamping state of the two titanium tube segments. This allows the end face of the just-cut titanium tube to instantly disengage from the two sides of the cutting blade 25, avoiding the rigid impact of the elastic rebound of the titanium tube after cutting on the cutting blade 25. This reduces the wear of the cutting blade 25, extends the tool life, and prevents burrs, chipping, and dimensional deviations caused by the rebound collision at the cut edge, ensuring the end face quality and length consistency of the titanium tube segmented products.

[0056] See Figure 4 A telescopic cylinder 101 is vertically mounted on one side of the connecting seat 21. A baffle 102 is connected to the top of the piston rod of the telescopic cylinder 101. During the cutting process, in order to prevent the industrial camera 103 from being damaged by the debris generated by the cutting of the titanium tube, the baffle 102 is pushed upward by the telescopic cylinder 101. After the baffle 102 moves upward, it is used to block the industrial camera 103. After the cutting is completed, the baffle 102 moves downward to continue the inspection operation.

[0057] Example 3: A method for fixed-length segmentation in titanium tube production, using a fixed-length segmentation device for titanium tube production as described above, includes the following steps: S1. Insert the titanium tube into the interior of the support assembly 7 and extend it to the top of the fixed-length assembly 8. During the extension process, use four baffles 834 to block the end of the titanium tube. The more specific steps in S1 are as follows: S11. The titanium tube passes through the top of the electric wheel 3 and the V-shaped frame 4, and passes under the positioning wheel 6 and the support assembly 7, extending to the top of the fixed length assembly 8. When the titanium tube is being transported, the pneumatic lifting platform drives the belt drive mechanism 91 and the drive wheel 9 to move upward, causing the drive wheel 9 to lift the titanium tube and contact the outer wall of the positioning wheel 6. At this time, the belt drive mechanism 91 drives the drive wheel 9 to rotate, thereby driving the titanium tube to be transported forward.

[0058] S12. When the end of the titanium tube extends to the position of the detection mechanism 83, the end of the titanium tube is blocked by four auxiliary rods 835.

[0059] S2. During the blocking process, if the end of the titanium tube is uneven, the four baffles 834 will be pushed to different degrees. After blocking, the baffles 834 will drive the hinge rod 833 to swing. The hinge rod 833 will synchronously drive the auxiliary rod 835 to swing, causing the micro switch 836 to move horizontally and retract the spring rod 837. When all four baffles 834 trigger the corresponding micro switch 836, the titanium tube will be in place at the fixed length.

[0060] S3. After the titanium tube is fixed in length, the titanium tube stops being transported. Then, the support component 7 limits the segmentation position of the titanium tube. The segmentation component 2 is used to segment the titanium tube. After the segmentation is completed, the titanium tube at the rear end continues to be transported forward, thereby pushing the segmented titanium tube out of the support component 7 and dropping it. The titanium tube at the rear end continues to be fixed in length and limited by the length-fixing component 8 and the support component 7, and can be segmented again by the segmentation component 2.

[0061] The more specific steps for S3 are as follows: S31. After the titanium tube reaches its set length, the belt drive mechanism 91 descends away from the titanium tube, the titanium tube stops being transported and falls on top of the electric wheel 3 and the V-shaped frame 4. Then, the bidirectional electric slide rail 71 drives the two slide tables 72 to move closer to each other, causing the two collars 744 to move closer to each other, maintaining a cutting segment gap between the two collars 744, and the collars 744 make coarse adjustments to the large curvature of the titanium tube. At this time, the titanium tube rotates through the cooperation of the electric wheel 3 and the wheel body 54, and the industrial camera 103 captures the curvature of the titanium tube between the two collars 744 in real time.

[0062] S32. The titanium tube rotates at least one revolution. At this time, the bending of the titanium tube is adjusted to an upward bending state. Then, the pressing cylinder 745 drives the pressing block 747 to move down, thereby pressing down and correcting the upward bending titanium tube. At the same time, the buffer seat 746 supports the corrected titanium tube.

[0063] S33. After the titanium tube is straightened, the telescopic cylinder 101 drives the baffle 102 to move upward to block the industrial camera 103. The cutting blade 25 moves downward to start cutting. During the cutting process, the titanium tube is gradually segmented. When the cutting blade 25 is in place, the lower end moves down into the positioning groove 732. The laser sensor 734 detects that the cutting blade 25 has entered the positioning groove 732 through the through hole 733 on the side wall of the positioning groove 732. Then the detection data is transmitted to the external control system. The control system controls the bidirectional electric slide rail 71 to drive in the opposite direction. The two slides 72 separate from each other. At this time, since the titanium tube is in a clamped state and kept horizontal, the movement of the slides 72 drives the two segments of the titanium tube to separate quickly, reducing the damage of the cutting blade 25 to the end of the titanium tube.

[0064] S34. After the segmentation is completed, the titanium tube at the rear end continues to be conveyed forward, thereby pushing the segmented titanium tube out of the support component 7 and dropping it. The support component 7 is reset to its initial state, while the titanium tube at the rear end continues to be lengthened and restricted by the length-fixing component 8 and the support component 7, and can be segmented again by the segmentation component 2.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
