[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1As shown, the present invention discloses a fully automatic double-head chamfering device for pipes, comprising a machine base 1, on which a clamping, positioning, and transferring structure is provided. The clamping, positioning, and transferring structure includes a clamping device 2 and a transferring device 3. The clamping device 2 clamps and positions the pipe to be chamfered, and the transferring device 3 transfers the pipe to be chamfered from the clamping device 2. The clamping device 2 and the transferring device 3 are arranged along the Y-axis direction of the machine base 1, with the clamping device 2 positioned at the front end of the transferring device 3, and the clamping device 2 and the transferring device 3 arranged longitudinally to fully utilize the longitudinal space of the machine base 1.

[0026] The transfer device 3 is equipped with double-headed chamfering devices 4 fixed to the machine base 1 on both sides. The working ends of the double-headed chamfering devices 4 are arranged opposite each other. The transfer device 3 clamps and transfers the pipe material to be chamfered from the clamping device 2 to the working ends of the double-headed chamfering devices 4. The double-headed chamfering devices 4 simultaneously chamfer the two ends of the pipe material clamped in the transfer device 3, which can improve the working efficiency of the chamfering operation.

[0027] Below the transfer device 3 is a feeding structure 5 fixed to the machine base 1. After the chamfering operation is completed, the transfer device 3 releases the processed pipe material. Due to gravity, the pipe material falls to the feeding structure 5 and is then transported and collected by the feeding structure 5, which facilitates the collection of the processed pipe material.

[0028] A step-by-step feeding mechanism is provided on one side of the clamping device 2. The step-by-step feeding mechanism includes a feeding device 6 and a conveying device 7. The feeding end of the feeding device 6 is connected to the feeding end of the conveying device 7. The discharging end of the conveying device 7 faces the clamping device 2, so that the pipe material is conveyed from the feeding device 6 to the clamping device 2 via the conveying device 7, so that the pipe material is close to the clamping device 2. In use, the discharging end of the conveying device 7 can be fixed to the machine base 1 by means of plates or connectors, so that the conveying device 7 is not easy to shift when conveying pipes, and ensures the stability of the conveying operation.

[0029] A conveying robot 8 is provided between the clamping device 2 and the discharge end of the conveying device 7. The conveying robot 8 is fixed to the machine base 1. The conveying robot 8 conveys the pipe material between the clamping device 2 and the discharge end of the conveying device 7, so that the step-by-step feeding mechanism, clamping positioning and conveying structure and unloading structure 5 are connected, realizing the mechanized completion of a series of tasks such as feeding, conveying, processing and unloading, effectively improving the production efficiency of pipe material chamfering.

[0030] In use, the pipe is placed in the feeding device 6, and then conveyed from the feeding device 6 to the clamping device 2 via the conveying device 7. The pipe is brought close to the clamping device 2, and then the conveying robot 8 transfers the pipe from the conveying device 7 to the clamping device 2. After the pipe is clamped and positioned by the clamping device 2, the transfer device 3 moves the pipe between the working ends of the double-headed chamfering device 4. The working ends of the double-headed chamfering device 4 simultaneously chamfer the ends of the pipe clamped in the transfer device 3, efficiently completing the chamfering operation. For convenient control, a PLC controller can be electrically connected to the clamping device 2, the transfer device 3, the double-headed chamfering device 4, the feeding device 6, and the conveying device 7.

[0031] like Figure 2 and Figure 3 As shown, the clamping device 2 in this embodiment includes a first support member 21, which is a support column. The lower part of the first support member 21 is fixedly connected to the machine base 1 by means of bolt and screw hole engagement or welding, so that the first support member 21 is fixed to the machine base 1.

[0032] The upper part of the first support member 21 is provided with a clamping platform 22, which supports the pipe material. The bottom of the clamping platform 22 is fixedly connected to the first support member 21 by means of bolts and screw holes or welding, so that the clamping platform 22 is fixed to the first support member 21.

[0033] A positioning block 23 is provided on one side of the top of the clamping table 22. The positioning block 23 is fixedly connected to the clamping table 22 by means of bolt thread or welding, so that the positioning block 23 is fixed to the clamping table 22.

[0034] A clamping block 24 is provided on the other side of the clamping platform 22. The clamping block 24 is plate-shaped and is slidably connected to the clamping platform 22 and positioned opposite to the positioning block 23. A first driver 25, which is an electric cylinder, is provided at the end of the clamping block 24 opposite to the positioning block 23. The fixed end of the first driver 25 is fixedly connected to the clamping platform 22 by means of bolts and screw holes or welding, so that the first driver 25 is fixed to the clamping platform 22.

[0035] The output end of the first driver 25 is fixedly connected to the clamping block 24 by means of bolts and screw holes or welding, so that the clamping block 24 is displaced as the output end of the first driver 25 extends or retracts.

[0036] For ease of control, the PLC controller can be electrically connected to the first driver 25.

[0037] During operation, the conveying robot 8 transports the pipe material from the discharge end of the conveying device 7 to the clamping table 22, placing the pipe material horizontally in the clamping table 22 with the cut ends of the pipe material facing the positioning block 23 and the clamping block 24 respectively. The output end of the first driver 25 drives the clamping block 24 to extend towards the positioning block 23, so that the cut ends of the pipe material abut against the positioning block 23 and the clamping block 24 respectively, realizing the clamping device 2 clamping and positioning of the pipe material, which facilitates the transfer device 3 to clamp the pipe material. After the transfer device 3 clamps the pipe material, the output end of the first driver 25 drives the clamping block 24 to retract, so that the clamping block 24 moves away from the positioning block 23, realizing the release of the pipe material by the clamping device 2, which facilitates the transfer device 3 to transfer the pipe material.

[0038] like Figure 2 and Figure 3 As shown, the transfer device 3 in this embodiment includes a second support member 31, which is a support column. The lower part of the second support member 31 is fixedly connected to the machine base 1 by means of bolt and screw hole engagement or welding, so that the second support member 31 is fixed to the machine base 1.

[0039] The upper part of the second support member 31 is provided with a positioning platform 32 and a first transfer device 33. The positioning platform 32 is recessed at one end facing the clamping device 2 and a positioning groove 321 is provided. A slide rail 322 is longitudinally arranged in the positioning groove 321. The output end of the first transfer device 33 is connected to the sliding end of the slide rail 322 by a bolt and screw hole connection, so that the output end of the first transfer device 33 slides with the slide rail 322, so that the output end of the first transfer device 33 can be kept on the same horizontal plane when it extends or retracts, thereby improving the working stability of the output end of the first transfer device 33.

[0040] The positioning groove 321 has horizontally arranged limiting grooves 323 on both sides. A positioning limiting block 324 is installed within each limiting groove 323. A protrusion is provided on the end of the positioning limiting block 324 facing the limiting groove 323. The positioning limiting block 324 is slidably connected to the limiting groove 323 through the protrusion. The positioning limiting block 324 is connected to the positioning table 32 via a bolt and threaded connection, fixing the positioning limiting block 324 at the designated position in the limiting groove 323. The output end of the first transfer device 33 slides between the two positioning limiting blocks 324, which restricts the transfer direction of the output end of the first transfer device 33 and improves the working accuracy of the first transfer device 33.

[0041] A positioning fastener 325 is provided on the outer side of the positioning limit block 324. The positioning fastener 325 is a positioning plate, and multiple positioning plates are connected in an n-shape, so that the end of the positioning fastener 325 facing the limit groove 323 is open, and the end of the positioning fastener 325 away from the limit groove 323 is closed. The end of the positioning fastener 325 away from the limit groove 323 is connected to the fixed end of the first transfer device 33 by means of bolt and screw hole connection, so that the first transfer device 33 is fixed to the positioning platform 32.

[0042] The positioning fastener 325 has a fixing slot 326 at one end facing the limiting groove 323. The fixing slot 326 engages between the inner wall of the limiting groove 323 and the side wall of the positioning platform 32, fixing the positioning fastener 325 to the positioning platform 32. This also allows the positioning fastener 325 to slide within the limiting groove 323 and adjust its connection position with the positioning platform 32. After adjustment, the positioning fastener 325 can be fixed to the positioning platform 32 using a bolt and screw hole connection.

[0043] The output end of the first transfer device 33 faces the clamping table 22, and the clamping table 22 is provided with a second transfer device 34 at the end opposite to the second support member 31. The fixed end of the second transfer device 34 is fixedly connected to the clamping table 22 by bolt and screw hole engagement or welding, so that the second transfer device 34 is fixed to the clamping table 22. The output end of the second transfer device 34 slides between the positioning block 23 and the clamping block 24, so that the output end of the first transfer device 33 and the output end of the second transfer device 34 are positioned opposite each other, which facilitates the second transfer device 34 and the first transfer device 33 to cooperate in transferring the pipe material.

[0044] During operation, the output end of the first transfer device 33 extends toward the clamping table 22 and abuts against the rear end of the pipe material clamped in the clamping device 2, while the output end of the second transfer device 34 extends toward the first transfer device 33 and abuts against the front end of the pipe material clamped in the clamping device 2, thereby enabling the transfer device 3 to clamp the pipe material. The pipe material is then released through the clamping device 2, and the output end of the second transfer device 34 extends toward the first transfer device 33, while the output end of the first transfer device 33 retracts, thereby enabling the transfer device 3 to transfer the pipe material.

[0045] like Figure 3 As shown, the first transfer device 33 in this embodiment includes a second driver 331 and a first transfer clamp 332. The second driver 331 is an electric push rod. The fixed end of the second driver 331 is fixedly connected to the positioning and fixing member 325 by means of bolt and screw hole engagement or welding, so that the second driver 331 is fixed to the second support member 31.

[0046] A push rod 333 is provided between the output end of the second driver 331 and the first transfer clamp 332. The push rod 333 is rectangular. One end of the push rod 333 is connected to the output end of the second driver 331 through a bolt and screw hole, and the other end of the push rod 333 is connected to the first transfer clamp 332 through a bolt and screw hole. This allows the first transfer clamp 332 to be fixed to the output end of the second driver 331 and to move as the output end of the second driver 331 extends or retracts. This facilitates the second transfer device 34 and the first transfer device 33 to cooperate in transferring the pipe material. At the same time, the push rod 333 can increase the stroke of the second driver 331.

[0047] The push rod 333 slides between two positioning limit blocks 324 on both sides, ensuring precise sliding direction. The bottom of the push rod 333 connects to the sliding end of the slide rail 322, stabilizing the push rod 333 as it slides with the second driver 331. A retraction stop block 334 is provided at one end of the push rod 333 near the first transfer clamp block 332. The two retraction stop blocks 334 are connected to both sides of the push rod 333 via slots and blocks for easy installation. When the second driver 331 drives the push rod 333 to retract, the retraction stop block 334 abuts against the positioning limit blocks 324, limiting the stroke of the second driver 331 and facilitating positioning when the output end of the second driver 331 retracts.

[0048] The second transfer device 34 includes a third driver 341 and a second transfer clamp 342. The third driver 341 is an electric push rod. The fixed end of the third driver 341 is fixedly connected to the clamping table 22 by means of bolts and screw holes or welding, so that the third driver 341 is fixed to the clamping table 22.

[0049] The output end of the third driver 341 is fixedly connected to the end of the second transfer clamp 342 away from the second support member 31 by means of bolt and screw hole or welding, so that the second transfer clamp 342 is fixed to the output end of the third driver 341 and moves as the output end of the third driver 341 extends or retracts, so that the second transfer device 34 can cooperate with the first transfer device 33 to transfer the pipe material.

[0050] Preferably, an extension push rod and a protective shell are provided between the third driver 341 and the second transfer clamp 342. The extension push rod slides inside the protective shell. One end of the protective shell near the third driver is fixedly connected to the fixed end of the third driver 341. One end of the extension push rod is fixedly connected to the output end of the third driver 341, and the other end of the extension push rod is fixedly connected to the second transfer clamp 342. The extension push rod can increase the stroke of the third driver 341, while the protective shell restricts the sliding direction of the extension push rod, which can improve the sliding accuracy of the extension push rod and improve the accuracy of the second transfer device 34 in transferring the tube material.

[0051] The first transfer clamping block 332 has a positioning hole 335 at one end facing the second transfer clamping block 342. The second transfer clamping block 342 has a positioning pin 343 corresponding to the positioning hole 335. When the first transfer clamping block 332 and the second transfer clamping block 342 abut, the positioning pin 343 is inserted into the positioning hole 335, which facilitates observation and verification of the horizontal symmetry of the first transfer clamping block 332 and the second transfer clamping block 342. This ensures that the first transfer clamping block 332 and the transfer clamping block 332 maintain a horizontal state when clamping the pipe material, improving the working accuracy of the transfer device 3 and improving the accuracy of the pipe material chamfering operation.

[0052] For ease of control, the PLC controller can be electrically connected to the second driver 331 and the third driver 341.

[0053] During operation, the first transfer clamp 332 extends towards the clamping table 22 along with the output end of the second driver 331 and abuts against one side of the pipe material clamped in the clamping device 2. The second transfer clamp 342 extends towards the first transfer device 33 along with the output end of the third driver 341 and abuts against the other side of the pipe material clamped in the clamping device 2, thus enabling the transfer device 3 to clamp the pipe material. When the clamping device 2 releases the pipe material, the output end of the third driver 341 extends towards the first transfer clamp 332, while the output end of the second driver 331 retracts, causing the first transfer clamp 332 and the second transfer clamp 342 to clamp and displace the pipe material, thus enabling the transfer device 3 to transfer the pipe material. After the pipe material completes the chamfering operation, the output end of the third driver 341 retracts, causing the first transfer clamp 332 and the second transfer clamp 342 to separate, and the pipe material that has completed the chamfering operation can be released from the transfer device 3 and fall into the unloading structure 5.

[0054] like Figure 1 As shown, the double-head chamfering device 4 in this embodiment includes a vertical drive 41 and a horizontal drive 42. Both the vertical drive 41 and the horizontal drive 42 are linear slide modules. The fixed end of the vertical drive 41 is connected to the machine base 1 by means of bolt and screw hole engagement or welding, so that the vertical drive 41 is fixed to the machine base 1.

[0055] Two horizontal actuators 42 are respectively set on both sides of the output end of the vertical actuator 41. The fixed end of the horizontal actuator 42 is fixedly connected to the output end of the vertical actuator 41 by means of bolt and screw hole, so that the horizontal actuator 42 is fixed to the output end of the vertical actuator 41. The two horizontal actuators 42 move up and down with the output end of the vertical actuator 41, which facilitates the working end of the double-headed chamfering device 4 to chamfer the cut of the pipe material clamped in the transfer device 3.

[0056] Both horizontal actuators 42 are equipped with chamfering machines 43 at their output ends. The fixed ends of the chamfering machines 43 are fixedly connected to the output ends of the horizontal actuators 42 through bolt and screw hole engagement, so that the two chamfering machines 43 are fixed to the output ends of the two horizontal actuators 42 respectively, and the two chamfering machines 43 slide left and right with the output ends of the horizontal actuators 42 to move, so that the working end of the double-headed chamfering device 4 can perform chamfering operation on the cut of the pipe material clamped in the transfer device 3.

[0057] The cutters of the two chamfering machines 43 are arranged opposite each other and located on both sides of the first transfer clamping block 332 and the second transfer clamping block 342, so that the working end of the double-headed chamfering device 4 can simultaneously perform chamfering operations on the two ends of the pipe material clamped in the transfer device 3, and complete the chamfering operation of the pipe material cutting end with high efficiency.

[0058] For ease of control, the vertical drive 41, the horizontal drive 42, and the chamfering machine 43 can be electrically connected via a PLC controller.

[0059] During operation, the transfer device 3 transfers the pipe material between the cutter heads of the two chamfering machines 43. The output end of the vertical drive 41 and the output ends of the two horizontal drives 42 cooperate to bring the cutter heads of the two chamfering machines 43 close to the two ends of the pipe material, so that the working end of the double-head chamfering device 4 can perform chamfering operation on the two ends of the pipe material clamped in the transfer device 3.

[0060] like Figure 2 As shown, the feeding structure 5 in this embodiment includes a feeding platform 51 connected between the first support member 21 and the first support member 21. A feeding chute 52 is provided on the top of the feeding platform 51. One end of the feeding chute 52 is connected to the top of the feeding platform 51 by means of bolt thread or welding. The other end of the feeding chute 52 is connected to the machine base 1. The horizontal height of the end of the feeding chute 52 connected to the feeding platform 51 is higher than the horizontal height of the end of the feeding chute 52 connected to the machine base 1, so that after the pipe material that has completed the chamfering operation falls into the feeding chute 52, it slides from the end of the feeding chute 52 connected to the feeding platform 51 to the end of the feeding chute 52 connected to the machine base 1. A collection area is set at the end of the feeding chute 52 connected to the machine base 1, so that the pipe material that has completed the chamfering operation can be collected conveniently.

[0061] like Figure 4 As shown, the feeding device 6 in this embodiment includes a support 61. A feeding chute 62 is provided on the top of the support 61. A feeding inclined surface 621 is provided in the feeding chute 62, which is arranged along the feeding end of the feeding chute 62 to the feeding end of the feeding chute 62. The horizontal height of the feeding end of the feeding inclined surface 621 is higher than the horizontal height of the feeding end of the feeding inclined surface 621, so that the pipe material to be processed slides along the feeding inclined surface 621 from the feeding end of the feeding chute 62 to the feeding end of the feeding chute 62 under the action of gravity.

[0062] The feeding end of the feeding chute 62 is connected to the feeding end of the transmission device 7 by means of bolts and screw holes, so that the feeding device 6 and the transmission device 7 are connected, which facilitates the feeding chute 62 to convey to the transmission device 7.

[0063] A lifting platform 63 is provided on the inner wall of the feeding end of the feeding chute 62. The lifting platform 63 is slidably connected to the inner wall of the feeding end of the feeding chute 62. A fourth driver 64 for driving the lifting platform 63 to slide is provided between the feeding end of the feeding chute 62 and the support 61. The fourth driver 64 is an electric cylinder.

[0064] The fixed end of the fourth actuator 64 is fixedly connected to the bracket 61 by means of bolts and screw holes or welding, so that the fourth actuator 64 is fixed to the bracket 61.

[0065] The output end of the fourth driver 64 is connected to the lifting platform 63 through a plate, so that the lifting platform 63 moves as the output end of the fourth driver 64 extends or retracts.

[0066] A fixed platform 65 is provided between the two lifting platforms 63. The lifting platforms 63 and the fixed platform 65 are arranged in a stepped manner to facilitate the conveying of the pipe material in the feeding chute 62 to the conveying device 7.

[0067] The top of the lifting platform 63 is provided with a first inclined surface 66, and the fixed platform 65 is provided with a second inclined surface 67 corresponding to the first inclined surface 66. Both the first inclined surface 66 and the second inclined surface 67 are inclined downward towards the conveying device 7. The pipe material in the feeding chute 62 is conveyed to the conveying device 7 through the cooperation of the first inclined surface 66 and the second inclined surface 67.

[0068] During operation, when the output end of the fourth driver 64 is in a retracted state, the lifting platform 63 descends along with the output end of the fourth driver 64, so that the top of the lifting platform 63 near the feeding end of the feeding ramp 621 is level with the horizontal plane of the feeding end of the feeding ramp 621. The first inclined surface 66 is below the pipe material in the feeding chute 62. Due to gravity, the pipe material in the feeding chute 62 slides from the feeding end of the feeding ramp 621 onto the first inclined surface 66. The output end of the fourth driver 64 extends, and the lifting platform 63 rises along with the output end of the fourth driver 64. The first inclined surface 66 pushes the pipe material against the side wall of the adjacent fixed platform 65 as it rises. When the lower end of the first inclined surface 66 rises to be level with the top of the adjacent fixed platform 65, the pipe material rises due to gravity. The tube slides from the first inclined surface 66 onto the second inclined surface 67 of the adjacent fixed platform 65. The second inclined surface 67 presses the tube against the side wall of the adjacent lifting platform 63. When the output end of the fourth driver 64 retracts, the lifting platform 63 descends with the output end of the fourth driver 64. The top of the adjacent lifting platform 63 is flush with the lower part of the second inclined surface 67 of the adjacent fixed platform 65. Due to gravity, the tube slides from the second inclined surface 67 onto the adjacent first inclined surface 66. This process is repeated until the first inclined surface 66 of the last lifting platform 63 presses the tube against the inner wall of the feeding end of the feeding chute 62 and transports it to the feeding end of the transmission device 7, thus completing the transport of the tube from the feeding chute 62 to the transmission device 7.

[0069] like Figure 4 As shown, the transmission device 7 in this embodiment includes a transmission frame 71. A driving wheel 72 and a driven wheel 73 are rotatably arranged at both ends of the transmission frame 71. The driving wheel 72 is connected to the shaft of the driving wheel 72 through the output shaft of the motor, so that the driving wheel 72 has rotational power.

[0070] A conveyor belt 74 is fitted between the driving wheel 72 and the driven wheel 73. The driving wheel 72 and the driven wheel 73 tension the conveyor belt 74. The driving wheel 72 drives the conveyor belt 74 to rotate, so that the conveying device 7 can transfer the pipe material.

[0071] The conveyor frame 71 is provided with a conveyor loading port 711 at the unloading end of the feeding chute 62. The unloading end of the feeding chute 62 is connected to the conveyor frame 71 at the position of the conveyor loading port 711, so that the tube material enters the conveyor belt 74 from the feeding chute 62 through the conveyor loading port 711.

[0072] A first guard plate 75 and a second guard plate 76 are provided on both sides of the conveyor frame 71. The first guard plate 75 is located on the side of the conveyor frame 71 facing the unloading end of the feeding chute 62 and is fixedly connected to the conveyor frame 71 by bolts and screw holes. The second guard plate 76 is located opposite to the first guard plate 75 and is fixedly connected to the conveyor frame 71 by bolts and screw holes. A third guard plate 77 is provided on the end of the conveyor frame 71 facing the clamping device 2 and is fixedly connected to the conveyor frame 71 by bolts and screw holes. The first guard plate 75 and the second guard plate 76 reduce the drop of pipe material in the conveyor belt 74 and guide the pipe material during transport. The third guard plate 77 blocks the pipe material in the conveyor belt 74 and stops it at the discharge end of the conveying device 7, facilitating subsequent transport of the pipe material.

[0073] For ease of control, a PLC controller can be electrically connected to the motor that drives the drive wheel 72 to rotate.

[0074] like Figure 4 As shown, in this embodiment, the first guard plate 75 is provided with an extension guard plate 751 at one end facing the conveyor feed port 711. The extension guard plate 751 is fixedly connected to the conveyor frame 71 by means of bolts and screw holes, so that the extension guard plate 751 is fixed to the conveyor frame 71.

[0075] A limiting plate 78 is provided between the extension guard plate 751 and the second guard plate 76. The second guard plate 76 is provided with an adjustment groove 761 corresponding to a section of the conveyor feed port 711. One end of the limiting plate 78 is slidably connected to the adjustment groove 761, and the other end of the limiting plate 78 abuts against the extension guard plate 751. The abutment position of the limiting plate 78 and the extension guard plate 751 can be adjusted by sliding the position of the limiting plate 78 and the adjustment groove 761.

[0076] The specifications of the pipe are that the length of the pipe is greater than the width of the pipe, which is greater than the height of the pipe. By leaving a feeding gap 79 between the limiting plate 78 and the conveyor belt 74 for the pipe to pass through, the distance of the feeding gap 79 is greater than the height of the pipe and less than the width of the pipe. The distance between the first guard plates 75 is less than the length of the pipe and greater than the width of the pipe, so that the pipe is conveyed on the conveyor belt 74 in a horizontally flat state, thus achieving the regularity of the pipe conveying state.

[0077] The top of the lifting platform 63 and the fixed platform 65 are provided with a third inclined surface 68 at one end of the limiting plate 78. The third inclined surface 68 is inclined downward towards the feeding end of the feeding chute 62. The pipe material blocked by the limiting plate 78 can slide back into the feeding chute 62 through the third inclined surface 68.

[0078] like Figure 5 As shown, the conveying robot 8 in this embodiment includes a fixed frame 81, a fifth driver 82, a sixth driver 83 and a seventh driver 84 arranged along the discharge end of the conveying device 7 toward the clamping device 2. The fifth driver 82 is a linear sliding platform, the sixth driver 83 is a linear electric cylinder and the seventh driver 84 is an electric finger.

[0079] The lower end of the fixed frame 81 is fixedly connected to the machine base 1 by means of bolts and screw holes or welding, so that the fixed frame 81 is fixed to the machine base 1.

[0080] The fixed end of the fifth actuator 82 is connected to the top of the fixed frame 81 by means of bolt thread or welding, so that the fifth actuator 82 is connected to the fixed frame 81.

[0081] The fixed end of the sixth driver 83 is connected to the output end of the fifth driver 82 by means of bolt and screw holes or welding, thereby connecting the sixth driver 83 and the fifth driver 82. The fixed end of the seventh driver 84 is connected to the output end of the sixth driver 83 by means of bolt and screw holes or welding, thereby connecting the seventh driver 84 and the sixth driver 83, and thus connecting the fifth driver 82, the sixth driver 83, and the seventh driver 84.

[0082] The output end of the sixth driver 83 is vertically downward, facilitating the sixth driver 83 to drive the seventh driver 84 closer to the tube material. The output end of the seventh driver 84 is also vertically downward, facilitating the seventh driver 84's output end to grip the tube material. The output end of the fifth driver 82 is slidably positioned along the discharge end of the conveying device 7 towards the clamping device 2, allowing the output end of the fifth driver 82 to reciprocate between the discharge end of the conveying device 7 and the clamping device 2, thus enabling the output end of the seventh driver 84 to grip the tube material and reciprocate between the discharge end of the conveying device 7 and the clamping device 2.

[0083] For ease of control, the PLC controller can be electrically connected to the fifth driver 82, the sixth driver 83, and the seventh driver 84.

[0084] During operation, the output of the fifth driver 82 drives the sixth driver 83 and the seventh driver 84 toward the discharge end of the transmission device 7. When they reach directly above the discharge end of the transmission device 7, the output of the sixth driver 83 extends, bringing the output of the seventh driver 84 close to the tube material at the discharge end of the transmission device 7. The output of the seventh driver 84 retracts to clamp the tube material. The output of the sixth driver 83 retracts, moving the seventh driver 84 away from the discharge end of the transmission device 7. The output of the fifth driver 82 drives the sixth driver 83 and the seventh driver 84 toward the clamping device 2, bringing them close to the clamping device 2. When they reach directly above the clamping device 2, the output of the sixth driver 83 extends, bringing the output of the seventh driver 84 close to the clamping device 2. The output of the seventh driver 84 opens to place the tube material on the clamping table 22, completing the transfer of the tube material between the discharge end of the transmission device 7 and the clamping device 2.

[0085] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
