Abstract
Description
Technical Field
[0001] This utility model relates to the field of welded pipe processing technology, and in particular to a cutting device for welded pipe processing. Background Technology
[0002] Welded steel pipes, also known as welded tubes, are steel pipes made by rolling and welding steel plates or strips. The production process of welded steel pipes is simple, efficient, and offers a wide variety of specifications with low equipment investment, but their strength is generally lower than that of seamless steel pipes. During use, welded pipes often need to be cut as needed, but existing welded pipe cutting devices have some problems in operation:
[0003] 1. Low level of automation. Existing welded pipe cutting devices require constant adjustment of the welded pipe's position during use. Furthermore, because the cutting process cannot be completed in one go, the welded pipe needs to be rotated during the cutting process. However, the rotation process in existing welded pipe cutting devices requires manual rotation, resulting in a low overall level of automation.
[0004] 2. Poor adaptability. Existing welded pipe cutting devices cannot effectively push welded pipes during the cutting process, requiring manual pushing. Furthermore, they cannot quickly fix welded pipes of different sizes during the cutting process, resulting in a significant time commitment for fixing the pipes. Consequently, the overall adaptability of the cutting device is poor. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cutting device for welded pipe processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cutting device for welded pipe processing includes a workbench. Symmetrically distributed mounting brackets are welded to the outer wall of one side of the top of the workbench. A first electric telescopic rod is bolted to the top of the mounting brackets. An arc-shaped pressure plate is connected to the piston rod at the bottom of the first electric telescopic rod, and an arc-shaped groove shell is provided directly below the arc-shaped pressure plate. A guide rail is parallel to the width direction at one end of the top of the workbench, and a guide block is slidably inserted into the inner wall of the guide rail. A first servo motor is fixed to the top of the guide block by screws, and a cutting blade is connected to the output shaft of the first servo motor. A second electric telescopic rod is provided on one side of the guide block. A rotating disk is rotatably mounted at the center of the top of the workbench, and a drive motor is connected to the bottom of the rotating disk. A sliding groove is opened on the top of the rotating disk along the width direction, and a sliding block is slidably inserted into the inner wall of the sliding groove. A fixing plate is welded to the outer wall of the top of the sliding block, and a third electric telescopic rod is fixed to the outer wall of one side of the fixing plate by screws.
[0008] As a further embodiment of this utility model: the inner wall of the arc-shaped groove shell is welded with compression springs that are equally distributed in an arc shape, and the outer wall of the top of the compression springs is welded with an arc-shaped fixing plate, and the inner wall of the arc-shaped fixing plate is welded with guide wheels that are equally distributed.
[0009] As a further embodiment of this utility model: the inner walls of both sides of the arc-shaped groove shell are provided with limiting grooves in the vertical direction, and the outer walls of both sides of the arc-shaped fixing plate are welded with limiting blocks, and the limiting grooves and limiting blocks are adapted to each other.
[0010] As a further embodiment of this utility model: a first servo cylinder is fixed to the outer walls of both ends of the top of the fixed plate, and a first synchronous toothed roller is rotatably arranged between the two first servo cylinders.
[0011] As a further embodiment of this utility model: a second servo cylinder is symmetrically distributed at one end of the top of the fixed plate, and a second synchronous toothed roller is rotatably connected between the second servo cylinders.
[0012] As a further embodiment of this utility model: a synchronous belt is provided between the second synchronous toothed roller and the first synchronous toothed roller, and one end of the second synchronous toothed roller is connected to a second servo motor through a coupling.
[0013] As a further improvement of this utility model: the arc-shaped pressure plate is located directly above the arc-shaped groove shell, and the size of the arc-shaped pressure plate is adapted to the inner wall size of the arc-shaped groove shell.
[0014] Compared with the prior art, the present invention provides a cutting device for welded pipe processing, which has the following advantages:
[0015] 1. The welded pipe cutting device designed in this paper utilizes the cooperation between the guide wheel and the top arc-shaped pressure plate during the cutting process of the welded pipe to quickly squeeze and fix welded pipes of different models, preventing the welded pipes from sliding during the cutting process. In addition, the compression spring at the bottom of the guide wheel can lift the guide wheel to facilitate the subsequent sliding treatment of the welded pipes.
[0016] 2. The welding pipe cutting device designed in this paper, in order to facilitate the rotation of the welding pipe during the cutting process, after the welding pipe is limited and fixed, a synchronous belt with adjustable tilt direction is set in the middle and closely attached to the bottom of the welding pipe. The synchronous belt is driven to rotate by a second servo motor, thereby driving the welding pipe to rotate. When it is necessary to push the welding pipe, it is only necessary to tilt the synchronous belt in a staggered manner and then drive it to move the welding pipe forward.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1:
[0025] A cutting device for processing welded pipes, in this embodiment, such as... Figure 1-4 As shown, the workbench includes a worktable 1. Symmetrically distributed mounting brackets 2 are welded to the outer wall of one side of the top of the workbench 1. A first electric telescopic rod 3 is bolted to the top of the mounting brackets 2. An arc-shaped pressure plate 4 is connected to the piston rod at the bottom of the first electric telescopic rod 3, and an arc-shaped groove shell 5 is provided directly below the arc-shaped pressure plate 4. A guide rail 9 is parallel to the width direction at one end of the top of the workbench 1, and a guide block 10 is slidably inserted into the inner wall of the guide rail 9. A first servo motor 11 is fixed to the top of the guide block 10 by screws. The output shaft of the first servo motor 11 is connected to the cutting blade 12. A second electric telescopic rod 13 is provided on one side of the guide block 10. A rotating disk 14 is rotatably installed at the top center of the workbench 1. A drive motor 15 is connected to the bottom of the rotating disk 14. A sliding groove 16 is opened on the top of the rotating disk 14 along the width direction. A sliding block 17 is slidably inserted into the inner wall of the sliding groove 16. A fixing plate 18 is welded to the top outer wall of the sliding block 17. A third electric telescopic rod 19 is fixed to one side of the outer wall of the fixing plate 18 by screws.
[0026] During the cutting and processing of welded pipes, the guide wheel 8 and the top arc-shaped pressure plate 4 work together to quickly squeeze and fix welded pipes of different models, preventing the welded pipes from sliding during the cutting process. In addition, the compression spring 6 set at the bottom of the guide wheel 8 can lift the guide wheel 8, which facilitates the subsequent sliding processing of the welded pipes.
[0027] The inner wall of the arc-shaped groove shell 5 is welded with compression springs 6 distributed at equal intervals in an arc shape, and the outer wall of the top of the compression springs 6 is welded with an arc-shaped fixing plate 7. The inner wall of the arc-shaped fixing plate 7 is welded with guide wheels 8 distributed at equal intervals. The inner walls of both sides of the arc-shaped groove shell 5 are opened with limit grooves in the vertical direction, and the outer walls of both sides of the arc-shaped fixing plate 7 are welded with limit blocks. The limit grooves and limit blocks are adapted to each other.
[0028] The top two ends of the fixed plate 18 are each fixed with a first servo cylinder 20, and a first synchronous toothed roller 21 is rotatably arranged between the two first servo cylinders 20.
[0029] The top end of the fixed plate 18 is provided with symmetrically distributed second servo cylinders 22, and the second servo cylinders 22 are rotatably connected to each other by a second synchronous toothed roller 23.
[0030] During the cutting process of the welded pipe, in order to facilitate the rotation of the welded pipe, after the welded pipe is fixed in a limited position, a synchronous belt 24 with an adjustable tilt direction is set in the middle and closely attached to the bottom of the welded pipe. The second servo motor 25 drives the synchronous belt 24 to rotate, thereby driving the welded pipe to rotate. When it is necessary to push the welded pipe, it is only necessary to tilt the synchronous belt 24 in a staggered manner and then drive it to move the welded pipe forward.
[0031] In this embodiment, the cutting device is first connected to an external power source. Then, the welded pipe to be cut is placed on the inner wall of the arc-shaped groove shell 5 at the top of the workbench 1. The compression spring 6 lifts the arc-shaped fixing plate 7, causing the guide wheel 8 to extend out of the arc-shaped groove shell 5, facilitating the movement of the welded pipe. At this time, the first electric telescopic rod 3 drives the arc-shaped pressure plate 4 to press down, thus fixing the welded pipe. When the welded pipe needs to move forward, the third electric telescopic rod 19 first drives the sliding block 17 to move, causing the synchronous belt 24 to misalign. Then, the first servo... The servo cylinder 20 lifts the first synchronous toothed roller 21, and then the second servo cylinder 22 lifts the second synchronous toothed roller 23. After that, the second servo motor 25 drives the synchronous belt 24 to rotate and drive the welded pipe to rotate forward. After moving to the predetermined position, the arc-shaped pressure plate 4 presses it down and fixes it. Then, the first servo motor 11 drives the cutting blade 12 to rotate and cut the welded pipe. If the welded pipe cannot be cut in one go and needs to be rotated during the cutting process, the synchronous belt 24 is adjusted to a horizontal position and lifted. Then the welded pipe is rotated to cut it.
[0032] Example 2:
[0033] A cutting device for processing welded pipes, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: a synchronous belt 24 is provided between the second synchronous toothed roller 23 and the first synchronous toothed roller 21, and one end of the second synchronous toothed roller 23 is connected to a second servo motor 25 through a coupling. The arc-shaped pressure plate 4 is located directly above the arc-shaped groove shell 5, and the size of the arc-shaped pressure plate 4 is adapted to the inner wall size of the arc-shaped groove shell 5.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
