Description

Technical Field

[0001] This utility model relates to the field of high-frequency straight seam welded pipe processing technology, and in particular to a novel burr removal device for high-frequency straight seam welded pipe. Background Technology

[0002] High-frequency straight seam welded pipe is a manufacturing process that utilizes high-frequency current to generate heat between steel strips, rapidly heating the welding area to a welding state, thereby melting the steel strips and joining them into a steel pipe. It is widely used in metallurgy, petroleum, construction, coal mining, ports, and automotive industries. After welding, high-frequency straight seam welded pipes are prone to leaving weld slag and burrs at the weld joint. These burrs need to be completely removed using a deburring device after welding to ensure pipe quality. However, existing high-frequency welded pipe deburring systems typically use grinding wheels fixed to the motor end, making them unadjustable and unsuitable for different pipe specifications. Furthermore, fixing the high-frequency welded pipe with bolts is usually cumbersome.

[0003] Existing patent CN217991939U discloses a device for deburring the inside of high-frequency welded pipes. This structure, through the arrangement of a grinding wheel, an arc-shaped grinding plate, a grinding layer, a push rod, a transmission rod, a turntable, a fixed plate, and a sleeve rod, solves the problem that existing high-frequency welded pipe deburring devices cannot adapt to different specifications of high-frequency welded pipes. By activating an electric telescopic rod, the arc-shaped grinding plate is brought into contact with the inner wall of the high-frequency welded pipe, thus facilitating adaptation to different specifications. Its operation is simple and can be performed simultaneously with fixing the outer wall. However, in practical use, after deburring the inside of high-frequency straight seam welded pipes, a large number of burrs remain inside the pipe, requiring subsequent cleaning by operators, which is inconvenient. Therefore, further improvement is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a new type of high-frequency straight seam welded pipe internal burr removal device.

[0005] This utility model is achieved through the following technical solution:

[0006] A novel high-frequency straight seam welded pipe internal burr removal device includes a processing table, a support plate slidably mounted on the top of the processing table, a grinding motor fixedly mounted on the outer wall of the support plate, a shaft fixedly mounted on the output end of the grinding motor, a support frame fixedly mounted on the outer wall of the shaft, and a grinding plate slidably mounted inside the support frame.

[0007] To facilitate the removal of all burrs remaining on the inner wall of the pipe, the flipping structure further includes a flipping plate mounted on the top of the processing table. Two support blocks are fixedly mounted on the top of one end of the processing table, and one end of the flipping plate is located between the two support blocks. A pivot pin is provided between the flipping plate and the support blocks, and they are rotatably connected by the pivot pin. A positioning plate is fixedly mounted on the outside of the pivot rod. Positioning holes are provided at the connection points between the positioning plate and the corresponding support blocks. Positioning bolts are installed in the internal threads of the positioning holes. A sliding groove is provided at the bottom of the flipping plate, and a sliding rod is installed inside the sliding groove. A slider is slidably mounted on the outside of the sliding rod. Two support seats are fixedly mounted at the bottom of the slider, and a movable block is rotatably mounted between the two support seats. An electric push rod is fixedly mounted on the bottom of the processing table, and the output end of the electric push rod is fixedly connected to the movable block.

[0008] In order to install and fix the high-frequency straight seam welded pipe to be ground, two mounting plates with arc grooves are fixedly installed on the flip plate. An arc seat is fixedly installed inside the arc groove of the mounting plate. A clamp is installed on the mounting plate by bolts. The inside of the clamp is provided with an arc clamp plate with the same structure as the arc seat. A screw is connected to the top of the arc clamp plate. The screw is threaded to the surface of the clamp.

[0009] To facilitate extending the grinding plate and other structures to the deburring areas inside the pipe, and to make it easier to extend the grinding plate and other structures out of the pipe, two mounting slots are further provided on the top of the processing table and at the bottom of the support plate. A lead screw is rotatably mounted inside one mounting slot, and a guide rod is provided inside the other mounting slot. A threaded block and a guide block are respectively provided on the outside of the lead screw and the guide rod. A servo motor is provided at one end of the lead screw, and the servo motor is fixedly mounted at one end of the processing table, with the output end of the servo motor fixedly connected to the lead screw. The threaded block is threadedly connected to the outside of the lead screw, and the guide block is slidably connected to the guide rod. Both the threaded block and the guide block are fixedly mounted on the bottom of the support plate.

[0010] To ensure that the grinding plate fits the inner wall of pipes with different inner diameters, the support frame is hollow, and a movable plate is slidably disposed on the top of the grinding plate inside the support frame. Multiple elastic pads are installed on the movable plate, and the two ends of the elastic pads are fixedly connected to the movable plate and the support frame, respectively.

[0011] The beneficial effects of this utility model are:

[0012] This invention features a flipping structure. After the positioning bolts at the positioning plate and the corresponding support block are released, the output end of the electric push rod drives the movable block to rotate between the two support seats, and pushes the slider to slide inside the slide groove through the slide rod. This causes one end of the flipping plate to rotate between the two support blocks through the shaft pin, thereby causing the horizontal high-frequency straight seam welded pipe to tilt. This allows the burrs after grinding inside the high-frequency straight seam welded pipe to be discharged from the tilted high-frequency straight seam welded pipe. The arc-shaped seats on the two mounting plates can support the installation of the high-frequency straight seam welded pipe. The clamp is installed on the mounting plate with bolts, which can fix the high-frequency straight seam welded pipe between the arc-shaped seat and the clamp. Rotating the screw causes the screw to drive the arc-shaped clamp to extend downward, which can conveniently clamp and fix high-frequency straight seam welded pipes with different outer diameters.

[0013] Meanwhile, the servo motor drives the lead screw to rotate, causing the threaded block to slide and guide the support plate through the guide block and guide rod. The support plate drives the shaft, support frame, and grinding plate closer to the high-frequency straight seam welded pipe and extends to the area that needs deburring, thus facilitating the deburring of the inside of the high-frequency straight seam welded pipe. It also makes it easy to extend the shaft, support frame, and grinding plate out of the high-frequency straight seam welded pipe for easy cleaning of burrs and easy removal of the ground high-frequency straight seam welded pipe. The movable plate on the top of the grinding plate can slide inside the support frame, causing the elastic pad to be squeezed, which makes it easy to insert the grinding plate into the high-frequency straight seam welded pipe. After being squeezed, the elastic pad returns to its original position, allowing the grinding plate to fit against the inner wall of high-frequency straight seam welded pipes of different sizes, thus improving its application range.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] As attached Figure 1-6 As shown, this embodiment provides a novel high-frequency straight seam welded pipe internal burr removal device, including a processing table 1, a support plate 2 slidably installed on the top of the processing table 1, a grinding motor 3 fixedly installed on the outer wall of the support plate 2, a shaft 4 fixedly installed at the output end of the grinding motor 3, a support frame 5 fixedly installed on the outer wall of the shaft 4, and a grinding plate 6 slidably installed inside the support frame 5.

[0024] Specifically, in this structure, the grinding motor 3, which is fixedly installed on the outer wall of the support plate 2, can drive the shaft 4 to rotate inside the high-frequency straight seam welded pipe, and drive the support frame 5 and the grinding plate 6 to rotate. The grinding plate 6 is attached to the inner wall of the high-frequency straight seam welded pipe, and the rotating grinding plate 6 can grind and remove the burrs on the inner wall of the high-frequency straight seam welded pipe.

[0025] In this embodiment, as shown in the appendix Figure 1 , 2As shown in Figure 5, the flipping structure includes a flipping plate 7, which is installed on the top of the processing table 1. Two support blocks 8 are fixedly installed on the top of one end of the processing table 1. One end of the flipping plate 7 is located between the two support blocks 8. A shaft pin 9 is provided between the flipping plate 7 and the support blocks 8, and they are rotatably connected by the shaft pin 9. A positioning plate 29 is fixedly installed on the outside of the shaft rod 4. A positioning hole 30 is opened at the connection between the positioning plate 29 and the corresponding support block 8. A positioning bolt 31 is installed in the internal thread of the positioning hole 30. A sliding groove 10 is opened at the bottom of the flipping plate 7. A sliding rod 11 is installed inside the sliding groove 10. A slider 12 is slidably arranged on the outside of the sliding rod 11. Two support seats 13 are fixedly installed at the bottom of the slider 12. A movable block 14 is rotatably arranged between the two support seats 13. An electric push rod 15 is fixedly installed at the bottom of the processing table 1. The output end of the electric push rod 15 is fixedly connected to the movable block 14.

[0026] Specifically, in this structure, after the burrs inside the high-frequency straight seam welded pipe are ground and removed, a large number of burrs remain inside the pipe, which are not easy for operators to remove. Therefore, after the burrs inside the high-frequency straight seam welded pipe are ground and removed;

[0027] In the initial state, the operator releases the positioning bolts 31 between the positioning plate 29 and the support block 8. After grinding, the high-frequency straight seam welded pipe is horizontally installed on the top of the flip plate 7. At this time, the output end of the electric push rod 15 drives the movable block 14 to extend upward, so that the movable block 14 rotates between the two support seats 13 and pushes the slider 12 to slide inside the slide groove 10 through the slide rod 11. Since the positioning plate 29 outside the shaft pin 9 is no longer restricted by the positioning bolts 31, one end of the flip plate 7 can rotate between the two support blocks 8 through the shaft pin 9, thereby causing the horizontal high-frequency straight seam welded pipe to tilt, thereby expelling the burrs after grinding inside the high-frequency straight seam welded pipe from the tilted high-frequency straight seam welded pipe. After expelling, the flip plate 7 returns to a horizontal state, and the positioning plate 29 and the support block 8 are locked and fixed again by the positioning bolts 31 to prevent the flip plate 7 from flipping over for no reason.

[0028] In this embodiment, as shown in the appendix Figure 1 , 4 As shown, two mounting plates 16 with arc-shaped grooves are fixedly installed on the flip plate 7. An arc-shaped seat 17 is fixedly installed inside the arc-shaped groove of the mounting plate 16. A clamp 18 is installed on the mounting plate 16 by bolts. An arc-shaped clamp 19 with the same structure as the arc-shaped seat 17 is provided inside the clamp 18. A screw 20 is connected to the top of the arc-shaped clamp 19. The screw 20 is threadedly connected to the surface of the clamp 18.

[0029] Specifically, in this embodiment, the high-frequency straight seam welded pipe can be supported on the arc-shaped seats 17 on the two mounting plates 16. The clamp 18 is installed on the mounting plate 16 by bolts, which can fix the high-frequency straight seam welded pipe between the arc-shaped seats 17 and the clamp 18. For high-frequency straight seam welded pipes with different outer diameters, the screw 20 can be rotated to drive the arc-shaped clamp 19 to extend downward, which can conveniently clamp and fix high-frequency straight seam welded pipes with different outer diameters.

[0030] Example 2:

[0031] This embodiment provides a novel high-frequency straight seam welded pipe internal burr removal device, based on Embodiment 1, as shown in the attached figure. Figure 1 , 3 As shown, two mounting slots 21 are provided on the top of the processing table 1 and at the bottom of the support plate 2. A lead screw 22 is rotatably mounted inside one mounting slot 21, and a guide rod 23 is provided inside the other mounting slot 21. A threaded block 24 and a guide block 25 are respectively provided on the outside of the lead screw 22 and the guide rod 23. A servo motor 26 is provided at one end of the lead screw 22. The servo motor 26 is fixedly mounted at one end of the processing table 1, and the output end of the servo motor 26 is fixedly connected to the lead screw 22. The threaded block 24 is threadedly connected to the outside of the lead screw 22, and the guide block 25 is slidably connected to the guide rod 23. Both the threaded block 24 and the guide block 25 are fixedly mounted on the bottom of the support plate 2.

[0032] Specifically, in this structure, when the shaft 4, support frame 5, and grinding plate 6 are extended into the high-frequency straight seam welded pipe for grinding, the servo motor 26 drives the lead screw 22 inside one of the mounting slots 21 to rotate, so that the threaded block 24 drives the support plate 2 to slide and guide through the guide block 25 and guide rod 23. The support plate 2 drives the shaft 4, support frame 5, and grinding plate 6 to move closer to the high-frequency straight seam welded pipe and extend into the interior, thereby facilitating the grinding of burrs inside the high-frequency straight seam welded pipe. After grinding, the support plate 2 can drive the shaft 4, support frame 5, and grinding plate 6 to extend out from the high-frequency straight seam welded pipe, which facilitates the cleaning of burrs and the removal of the ground high-frequency straight seam welded pipe.

[0033] In this embodiment, as shown in the appendix Figure 3 , 6 As shown, the support frame 5 is hollow, and a movable plate 27 is slidably disposed inside the support frame 5 on the top of the grinding plate 6. Multiple elastic pads 28 are installed on the movable plate 27, and the two ends of the elastic pads 28 are fixedly connected to the movable plate 27 and the support frame 5 respectively.

[0034] Specifically, in the structure of this embodiment, the movable plate 27 at the top of the grinding plate 6 can slide inside the support frame 5, and the elastic pad 28 can be squeezed, which makes it easy to insert the grinding plate 6 into the high-frequency straight seam welded pipe. After being squeezed, the elastic pad 28 returns to its original position, which allows the grinding plate 6 to fit against the inner wall of high-frequency straight seam welded pipes of different sizes, thus improving the range of applications.

[0035] The principle of this utility model is as follows:

[0036] This application provides a novel high-frequency straight seam welded pipe internal burr removal device. In specific use, the high-frequency straight seam welded pipe to be deburred is first placed on the arc-shaped seat 17 on two mounting plates 16 for support, and the high-frequency straight seam welded pipe is fixed by clamp 18. The arc-shaped clamp 19 driven by the screw 20 can fix pipes with different outer diameters.

[0037] The operator first manually presses the grinding plate 6, causing the movable plate 27 to squeeze and reset the elastic pad 28, ensuring that the grinding plate 6 extends to the inner wall of the pipe. The servo motor 26 drives the lead screw 22 to move the support plate 2 towards the pipe, thereby driving the support frame 5 and the grinding plate 6 to extend into the inside of the pipe. After being squeezed, the elastic pad 28 resets, and the grinding plate 6 is now in contact with the inner wall of the pipe. Then, the grinding motor 3 drives the grinding plate 6 through the shaft 4 to grind the burrs on the inner wall of the pipe.

[0038] After grinding, the grinding plate 6 and other structures are extended from the inside of the pipe through the support plate 2 in the same way. The operator releases the positioning bolts 31 at the positioning plate 29 and the support block 8. The output end of the electric push rod 15 drives the movable block 14 to rotate between the two support seats 13 and pushes the slider 12 to slide inside the slide groove 10 through the slide rod 11. This allows one end of the flip plate 7 to rotate between the two support blocks 8 through the shaft pin 9, thereby causing the horizontal high-frequency straight seam welded pipe to tilt, and the burrs after grinding inside the high-frequency straight seam welded pipe to be discharged from the tilted high-frequency straight seam welded pipe.

[0039] After the burrs are removed, all structures are reset, and the deburred high-frequency straight seam welded pipe is taken out for use. The same process is used to process other high-frequency straight seam welded pipes.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
