Description

Technical Field

[0001] The utility model belongs to the field of steel pipe cutting, and particularly relates to an adjustable steel pipe cutting device. Background Art

[0002] Steel pipe cutting plays a critical role in many fields such as industrial production, construction and manufacturing. Through precise steel pipe cutting, steel pipe parts that meet specific size requirements can be obtained. However, most current steel pipe cutting devices have obvious limitations. Usually, these devices can only clamp and fix straight steel pipes. When faced with special-shaped steel pipes, such as curved steel pipes or steel pipes with different heights on both sides, shortcomings are exposed.

[0003] Existing devices are difficult to effectively fix special-shaped steel pipes. Since their design is based on the shape of straight steel pipes, they cannot provide comprehensive and uniform clamping force for curved or irregular steel pipes. This makes it difficult for the steel pipe to be stably fixed on the cutting device during the cutting process, and it is easy to shake. This shaking not only leads to inaccurate cutting dimensions, but also may cause safety accidents and harm to operators.

[0004] From the perspective of cutting accuracy, since the special-shaped steel pipe cannot be well fixed, the cutting tool will be affected by the shaking of the steel pipe during the cutting process, making it difficult to cut according to the predetermined path. This results in uneven edges of the cut steel pipe, which does not meet the requirements of precise processing. In order to solve this problem, we have developed an adjustable steel pipe cutting device. Utility Model Content

[0025] There are three groups of special-shaped clamping mechanisms 7, which are installed at equal intervals, and the output shaft of the servo motor 713 is connected to the rotating screw 72.

[0026] On the upper surface of the top plate 77, a top groove 711 is opened, and a pushing block 712 is installed in the top groove 711. The upper end of the pushing block 712 is connected to the moving clamping plate 79, and the right end of the clamping push rod 710 penetrates into the top groove 711 and is connected to the pushing block 712.

[0027] Please refer to Figures 1 to 3 As the first embodiment of the present invention: In actual use, the rotating screw 72 is driven to rotate by the servo motor 713. When the rotating screw 72 rotates, it can drive the slider 73 to slide in the hollow frame 71 through the threaded hole. At the same time, the slider 73 can drive the upper sliding plate 74 to slide horizontally, horizontally adjusting the clamping position of the moving clamping plate 79 and the fixed clamping plate 78. After the adjustment is completed, the top plate 77 can be driven to lift and adjust by the height-adjusting push rod 75, so as to adjust the clamping height of the moving clamping plate 79 and the fixed clamping plate 78. Then, the top plate 77 can be driven to rotate by the small motor 76, and the clamping position of the moving clamping plate 79 and the fixed clamping plate 78 is rotated and adjusted. Combining the above steps, according to the shape of different special-shaped steel pipes, the clamping positions of the three groups of special-shaped clamping mechanisms 7 can be adjusted to match the shape of the special-shaped steel pipe. After the adjustment is completed, the clamping position of the special-shaped steel pipe is placed between the moving clamping plate 79 and the fixed clamping plate 78, and then the pushing block 712 is pushed to move in the top groove 711 by the clamping push rod 710, which can drive the moving clamping plate 79 to approach the fixed clamping plate 78, so as to clamp the special-shaped steel pipe between them, and further enable the special-shaped steel pipe to be stably clamped and not easy to shake during the cutting process.

[0028] Above the cutting table 1, a first sliding table 2 is provided, and both sides of the lower part of the first sliding table 2 are connected to the cutting table 1 through fixed support rods 3.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 4, as the second embodiment of the present utility model: further elaborated on the basis of the first embodiment. After the special-shaped steel pipe is clamped and fixed, the first sliding table 2 can drive the second sliding table 4 to move horizontally below it, driving the cutting blade 10 to move horizontally to adjust the cutting position. When the second sliding table 4 moves, it can drive the linkage sliding rod 5 to move, and at the same time drive the lower end of the linkage sliding rod 5 to slide in the chute 6, improving the stability of the movement of the second sliding table 4. Then the second sliding table 4 can drive the cutting blade 10 to move back and forth below it to adjust the cutting position. Flexibly adjusting the position of the cutting blade 10 can easily meet various cutting requirements. After the adjustment is completed, the cutting blade 10 is driven to rotate by the rotating motor 9, and at the same time the cutting blade 10 is driven to descend by the telescopic push rod 8, so as to be able to quickly cut the special-shaped steel pipe.
