DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application (for the convenience of description and understanding, the following is Figure 2All other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the scope of protection of this application.

[0017] See also Figure 1-3 The present application provides a technical solution: a pipe cutting device for preparing a circular tube truss, comprising a support frame 6, a support table 7 is provided at the upper end of the support frame 6, and pipe clamping seats are provided on both sides of the upper end of the support table 7.

[0018] Pipe clamping seats are arranged on both sides of the upper end of the bracket table 7, which are used to fix the pipes to be cut; ensure the stability and positioning accuracy of the pipes during the cutting process, and prevent displacement due to external forces during the cutting process, which affects the cutting accuracy.

[0019] The pipe clamping seat includes a lower bracket 17, an upper support frame 4, a side support frame 15 and a locking seat 18. The upper end of the lower bracket 17 is hinged to the upper support frame 4. The locking seat 18 on one side of the upper support frame 4 is arranged corresponding to the lock located on one side of the lower bracket 17. The side support frames 15 are arranged on the front and rear sides of the lower bracket 17.

[0020] The upper support frame 4 is connected to the lower support frame 17 by a hinged connection to form a structure that can be opened and closed. When the pipe is placed on the lower support frame 17, the upper support frame 4 can be closed and pressed against the pipe to prevent the pipe from moving during the cutting process.

[0021] The locking seat 18 is located on one side of the upper support 4 and corresponds to the lock buckle on the lower bracket 17. When the upper support 4 is closed, the locking seat 18 will engage with the lock buckle to fix the position of the upper support 4 and ensure that the pipe is firmly fixed during the cutting process.

[0022] The side support frame 15 increases the stability of the pipe clamping seat and can prevent the entire clamping seat from tilting or shaking when subjected to cutting force, thereby ensuring that the position of the pipe during the cutting process is accurate and unchanged.

[0023] A pipe cutting assembly is arranged between the pipe clamping seats, and the pipe cutting assembly includes a moving group, an adjustment group and a cutting group. A pad assembly is arranged on the upper end of the moving group, and an adjustment group is arranged on the upper end of the pad assembly. The sliding side plate 3 on the adjustment seat is connected to the cutting group.

[0024] The pipe cutting assembly in the pipe cutting device is the core part for achieving precise cutting. It is composed of a moving group, an adjusting group and a cutting group to ensure the efficiency and accuracy of the cutting process; the moving group is responsible for the feeding and positioning of the pipe cutting knife 2 to ensure that the tool can move along the preset trajectory and align with the cutting position of the pipe; the pad assembly is located at the upper end of the moving group to provide support for the adjusting group to ensure the stability of the pipe during the cutting process and avoid deformation or position displacement of the pipe due to cutting force; the adjusting group adjusts the vertical position of the cutting group relative to the pipe to adapt to the cutting requirements of pipes of different diameters; the cutting group performs the actual cutting work, and the pipe cutting knife 2 rotates and cuts the pipe under the drive of the driving motor 1 to complete the pipe cutting task.

[0025] Furthermore, the moving group is mainly composed of a guide shaft mounting frame 8, a guide sliding shaft 14, a guide slide 13 and a driving cylinder 5. The guide shaft mounting frame 8 is arranged at both ends of the guide sliding shaft 14, and the guide slide 13 is slidably arranged on the outer side surface of the guide sliding shaft 14. The upper surface of the guide slide 13 is provided with a mounting base plate, and the telescopic end of the driving cylinder 5 is connected to the mounting base plate.

[0026] The guide shaft mounting frame 8 is used to fix the guide sliding shaft 14 to ensure its stability and linearity during cutting. The mounting frame 8 is usually designed to be strong enough to support the weight of the entire moving group and withstand cutting forces.

[0027] The guide slide shaft 14 provides a sliding track for the guide slide 13. Its function is to ensure that the guide slide 13 can move smoothly along a predetermined linear path, thereby accurately controlling the feeding direction of the pipe cutting assembly.

[0028] The telescopic end of the drive cylinder 5 is connected to the mounting base of the guide slide 13. The telescopic movement of the drive cylinder 5 drives the guide slide 13 along the guide slide shaft 14, thus achieving the feeding action of the pipe cutting assembly. The precise control capability of the drive cylinder 5 improves cutting accuracy.

[0029] Furthermore, the pad assembly includes a lower pad 12 and a supporting upper seat 11 , and the upper end of the lower pad 12 is provided with the supporting upper seat 11 .

[0030] The backing plate assembly provides a stable support for the pipe during the cutting process. The combination of the lower pad 12 and the support upper seat 11 reduces the vibration and impact generated during the cutting process, thereby improving the cutting quality and efficiency.

[0031] Furthermore, the adjustment group includes a mounting bracket 9, a lifting adjustment cylinder 10 and a sliding side plate 3. The upper end of the mounting bracket 9 is provided with a lifting adjustment cylinder 10, and the telescopic end of the lifting adjustment cylinder 10 is connected to the sliding side plate 3. The sliding side plate 3 is slidably set on the linear slide rail on one side of the mounting bracket 9.

[0032] The mounting bracket 9 is used to fix and support the entire adjustment group. It provides a mounting point for the lifting adjustment cylinder 10 and the sliding side plate 3, and also ensures the stability and structural rigidity of the entire adjustment group.

[0033] The lifting and adjusting cylinder 10 is mounted on the upper end of the mounting bracket 9, and its telescopic end is connected to the sliding side plate 3. The telescopic movement of the lifting and adjusting cylinder 10 accurately adjusts the vertical position of the sliding side plate 3, thereby changing the height of the pipe cutting assembly relative to the pipe fitting to accommodate the cutting requirements of pipe fittings of different diameters.

[0034] The sliding side plate 3 is mounted on a linear slide rail on one side of the mounting bracket 9 and can slide up and down along the rail. It serves as a mounting platform for the pipe cutting assembly and is also driven by a lifting and adjusting cylinder 10 to move vertically, ensuring that the pipe cutter 2 can accurately align with the cutting position of the pipe fitting.

[0035] Furthermore, the cutting group includes a driving motor 1 and a pipe cutter 2 , and the output end of the driving motor 1 is connected to the pipe cutter 2 .

[0036] When the pipe cutting device is started, the drive motor 1 begins to rotate, driving the pipe cutter 2 through its output terminal. Guided by the moving group, the pipe cutter 2 moves along the predetermined cutting position of the pipe, and the cutting force generated by the high-speed rotation cuts the pipe until it is completely separated.

[0037] Furthermore, an upper pressing seat 16 is provided in the concave portion of the upper end of the upper support frame 4 .

[0038] When the upper support frame 4 is closed and locked, the upper pressure seat 16 applies downward pressure, forming a comprehensive fixing system together with the lower bracket 17 and the side support frame 15, ensuring that the pipe does not move or deform during the cutting process. The concave design of the upper pressure seat 16 can slightly deform according to the diameter and shape of the pipe to better conform to the pipe surface and provide more stable support. The uniform pressure of the upper pressure seat 16 on the pipe can reduce the errors caused by pipe vibration or positional deviation during cutting, ensuring a clean cut edge and accurate dimensions.

[0039] During use: place the pipe to be cut on the lower bracket 17, ensure that the pipe is in the correct position, close the upper support 4, the upper pressure seat 16 presses the pipe, the locking seat 18 engages with the lock of the lower bracket 17 to ensure that the pipe is firmly fixed, start the driving cylinder 5, adjust the guide slide 13 to the appropriate position, align the pipe cutting knife 2 with the cutting point of the pipe, start the driving motor 1, and drive the pipe cutting knife 2 to rotate. At this time, the lifting and adjusting cylinder 10 adjusts the vertical position of the sliding side plate 3, and the pipe cutting knife 2 contacts the pipe. At this time, under the action of the lifting and adjusting cylinder 10, it continues to descend until the one-time cutting is successful, then release the upper support 4 and the locking seat 18, and take out the cut pipe.

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