Description

Technical Field

[0001] This utility model relates to the field of removing welding burrs from the inner cavity of high-frequency welded pipes, specifically a cutting device for high-frequency welded pipes. Background Technology

[0002] High-frequency welded pipe cutting is a key post-processing step in the production process. Its core objectives include adjusting the finished product size, optimizing the end face quality, and providing basic support for subsequent applications.

[0003] Cutting removes burrs and irregular end faces formed after welding, improving the smoothness of the pipe end. Depending on the burr removal method (such as cutting or rolling), the processing requirements of different types of welded pipes can be matched. Precision cutting also reduces the accumulation of errors in subsequent processing steps.

[0004] In the prior art, publication number "CN217513368U" discloses a multifunctional high-frequency welded pipe hot saw cutting device, including a limiting platform. A horizontal V-shaped limiting groove is opened on the left side of the limiting platform, and a welded pipe is placed on the V-shaped limiting groove. A pushing device is set on the left side of the welded pipe. The pushing device includes an electric push-pull rod and a push plate. A draining device is set on the right side of the V-shaped limiting groove. The draining device includes a draining pool, a draining plate, a worktable, and a slide. By setting a positioning device, the electric push-pull rod is controlled to push the welded pipe along the V-shaped limiting groove to the right to a suitable distance through the push plate. The extension end of the second electric cylinder is controlled to drive the two sets of arc-shaped clamps located above to move downward through the lifting plate. The two sets of arc-shaped clamps located below clamp the welded pipe. The extension end of the first electric cylinder is controlled to push the cutting mechanism forward through the slider to perform the cutting operation on the welded pipe.

[0005] However, existing technologies still have significant shortcomings, such as:

[0006] In the aforementioned devices and existing technologies, the tool is controlled by adjustable hydraulic or pneumatic pressure to cut into the inner wall of the welded pipe and directly scrape off the burrs. However, the cutting and milling torque of the tool is relatively large. The use of arc-shaped clamps to hold and fix the surface of the high-frequency welded pipe cannot eliminate the offset rotation of the high-frequency welded pipe under the rotating cutting state. This can easily cause the cutting depth of the tool to deviate from the cutting depth of the burrs in the inner cavity of the high-frequency welded pipe, affecting the burr removal effect of the inner cavity of the high-frequency welded pipe. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A cutting device for high-frequency welded pipes: including a counterweight base 1, a placement chamber 2, a slide rail frame 3, a moving stage 4, and a burr removal unit for the inner cavity of the high-frequency welded pipe welding area. The placement chamber 2 is located on the top of the counterweight base 1, the slide rail frame 3 is located at both ends of the counterweight base 1, the moving stage 4 is located in the top area of ​​the slide rail frame 3, and the burr removal unit for the inner cavity of the high-frequency welded pipe welding area is located in the area of ​​the moving stage 4 for removing burrs from the inner cavity of the end of the high-frequency welded pipe material installed in the placement chamber 2. The placement chamber 2 is provided with a placement cavity 21 inside.

[0026] The high-frequency welded pipe welding area cavity burr removal unit includes a positioning part, which includes an end bracket 6. The end bracket 6 is configured in two sets. A vertical guide rail 5 is installed on the outside of the placement chamber 2. One side of the end bracket 6 is installed on the moving end of the vertical guide rail 5. A stand 61 is installed on the bottom surface of the end bracket 6. An arc-shaped card plate 62 is installed on the surface of the stand 61. An arc-shaped rubber pad layer is provided at the bottom of the arc-shaped card plate 62.

[0027] The high-frequency welded pipe welding area cavity burr removal unit also includes a removal part, which includes a motor 41. The motor 41 is installed on one side of the moving table 4, and a burr cutting roller 42 is installed on the other side of the moving table 4. The burr cutting roller 42 is connected to the output end of the motor 41. A fixed seat 31 is installed on the top of the slide rail frame 3. An electric drive slide rail 32 is installed between the fixed seat 31 and the slide rail frame 3. The moving end of the electric drive slide rail 32 is fixed to the bottom of the moving table 4.

[0028] In this embodiment, by driving the electric drive slide rail 32, the electric drive slide rail 32 drives the moving table 4 to move toward the inner cavity area of ​​the high-frequency welded pipe end. After being driven by the motor 41, the burr cutting roller 42 in the area of ​​the moving table 4 is slowly inserted into the inner cavity of the high-frequency welded pipe end, thereby realizing the layer-by-layer removal and peeling of burrs in the inner cavity of the high-frequency welded pipe end, ensuring the burr removal effect of the high-frequency welded pipe inner cavity.

[0029] A U-shaped elastic rubber rod 8 is installed between the counterweight base 1 and the moving platform 4, and a debris bag 9 is installed at the bottom of the U-shaped elastic rubber rod 8.

[0030] In this embodiment, after the burr cutting roller 42 disengages, the chips that follow the burr cutting roller 42 can fall smoothly into the chip bag 9, reducing the difficulty of cleaning the subsequent workpiece processing area.

[0031] Example 2:

[0032] Based on Embodiment 1, this embodiment takes into account that if the burr is removed from the inner cavity of the high-frequency welded pipe by a rolling cutting method, the burr cutting roller 42 will exert a force on the high-frequency welded pipe after contacting the inner cavity of the high-frequency welded pipe, which will cause the high-frequency welded pipe to vibrate. In order to avoid the high-frequency welded pipe from vibrating and deviating from its position, an anti-vibration part is provided in this embodiment to avoid the above-mentioned problem.

[0033] The high-frequency welded pipe welding area cavity burr removal unit also includes a vibration prevention part, which includes a vertical guide rail 2 63. The vertical guide rail 2 63 is embedded in one side of the stand 61. A movable seat 71 is installed on the movable end of the vertical guide rail 2 63. A top plate 7 is installed on the top of the movable seat 71. Hard rubber plates 72 are symmetrically installed on both sides of the top plate 7.

[0034] The bottom surface of the rigid rubber sheet 72 is provided with an arc-shaped card surface 73.

[0035] The curved card surface 73 is also provided with a curved rubber pad layer.

[0036] In this embodiment, the vertical guide rail 2 63 can be driven to move the moving seat 71 and the rigid rubber plate 72 toward the surface of the high-frequency welded pipe. When the rigid rubber plate 72 moves and inserts between the high-frequency welded pipe and the placement cavity 21, the arc-shaped carding surface 73 at the bottom of the rigid rubber plate 72 will fit tightly against the surface of the high-frequency welded pipe, thereby symmetrically pressurizing and locking both sides of the welded pipe, reducing the shaking of the high-frequency welded pipe when removing burrs from the inner cavity, and further ensuring the burr removal effect of the high-frequency welded pipe.

[0037] Working principle: The operator places the high-frequency welded pipe to be deburred in the cavity into the placement cavity 21. The cavity 21 contains an anti-slip rubber layer to restrict the sliding of the high-frequency welded pipe. After the high-frequency welded pipe is placed in the placement cavity 21, the horizontal alignment of the two ends of the high-frequency welded pipe is performed so that the two sets of deburring rollers 42 can simultaneously remove the burrs in the cavity of the end of the high-frequency welded pipe to the same depth, ensuring that the two ends of the same set of high-frequency welded pipes can be effectively deburred.

[0038] After the high-frequency welded pipe is placed in place, the vertical guide rail 5 can be driven to move the end bracket 6 toward the surface of the high-frequency welded pipe. The upright 61 and the arc-shaped clamping plate 62 at the bottom of the end bracket 6 will move with the end bracket 6 until the arc-shaped clamping plate 62 moves and snaps onto the surface of the high-frequency welded pipe. The bottom surface of the arc-shaped clamping plate 62 is also arc-shaped. At the same time, an anti-slip rubber layer is also provided on the arc-shaped bottom surface of the arc-shaped clamping plate 62. When the surface of the high-frequency welded pipe is pressed, the high-frequency welded pipe can be pressed and anti-slip. Then, the electric drive slide rail 32 is driven to move the moving table 4 toward the inner cavity area of ​​the end of the high-frequency welded pipe. The burr cutting roller 42 in the area of ​​the moving table 4 is slowly inserted into the inner cavity of the end of the high-frequency welded pipe after being driven by the motor 41, thereby realizing the layer-by-layer removal and peeling of the burrs in the inner cavity of the end of the high-frequency welded pipe, ensuring the burr removal effect of the inner cavity of the high-frequency welded pipe.

[0039] In the process of removing burrs from the inner cavity of the high-frequency welded pipe, in order to prevent the burr cutting roller 42 from causing the high-frequency welded pipe to deflect, the vertical guide rail 2 63 can be driven to move the moving seat 71 and the hard rubber plate 72 toward the surface of the high-frequency welded pipe. When the hard rubber plate 72 moves and inserts between the high-frequency welded pipe and the placement cavity 21, the arc-shaped carding surface 73 at the bottom of the hard rubber plate 72 will fit tightly against the surface of the high-frequency welded pipe, thereby symmetrically applying pressure and locking on both sides of the welded pipe, reducing the shaking of the high-frequency welded pipe during the removal of burrs from the inner cavity, and further ensuring the removal effect of burrs from the inner cavity of the high-frequency welded pipe.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
