[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0024] Example: Figures 1-5 As shown, this utility model discloses a cold-bending pipe cutting device, comprising a cutting table 1, a vertically upward straight frame 2 on one side of the cutting table 1, a horizontal frame 3 on the straight frame 2, a horizontally arranged guide rail 4 on the horizontal frame 3, and a movable seat 5 that moves along the guide rail 4 on the guide rail 4. A laser cutting head 6 is mounted on the movable seat 5. A driving mechanism for driving the movable seat 5 to move along the horizontal frame 3 is provided on the horizontal frame 3. The device is characterized in that…

[0025] The cutting table 1 is provided with a slag receiving water tank 7 arranged parallel to the guide rail 4, and the top of the slag receiving water tank 7 is provided with a platform 8, and the platform 8 is provided with a clearance groove 9 arranged parallel to the moving direction of the laser cutting head 6. The slag receiving water tank 7 is provided with exhaust pipes 10 on both sides.

[0026] The cutting table 1 has positioning seats 111 on both sides of the clearance groove 9. Each positioning seat 111 has a positioning groove 12 for positioning the cold-bent pipe to be cut. The cutting table 1 also has a positioning mechanism 13 for positioning the cutting section. The positioning seats 111 are mounted on the cutting table 1 via a spacing adjustment mechanism. By providing positioning seats 111 on both sides of the clearance groove 9, and each positioning seat 111 having a positioning groove 12 for positioning the cold-bent pipe to be cut, and the positioning seats 111 being mounted on the cutting table 1 via a spacing adjustment mechanism, the spacing between the positioning seats 111 can be easily adjusted to accommodate cold-bent pipes of different specifications. Furthermore, the positioning mechanism 13 on the cutting table 1 provides good fixation for both sides of the cutting position, preventing offset during cutting and resulting in uneven cuts.

[0027] The spacing adjustment mechanism includes two parallel lead screws 14 and a guide rod 15 mounted on the cutting table 1. Each lead screw 14 has a sliding block 16 that moves along it, and each guide rod 15 has two moving blocks 17 that move along it. A moving plate 19 is installed between the sliding blocks 16 and the moving blocks 17, and the positioning seat 11 is fixed to the moving plate 19. This specific spacing adjustment mechanism adjusts the spacing between the positioning seats 111 to meet the positioning requirements of cold-bent pipes of different specifications. The adjustment is achieved by rotating the lead screws 14, which in turn moves the sliding blocks 16.

[0028] The positioning mechanism 13 includes an L-shaped positioning frame 20 mounted on the cutting table 1. The L-shaped positioning frame 20 has a vertically downward-pointing pressing telescopic cylinder 21.

This positioning mechanism positions the pipe body within the positioning groove, thus preventing displacement during cutting.

[0029] The movable plate 19 is fixed to the positioning seat 111 by bolts, making it easy to replace the positioning seat with different positioning slots, such as... Figure 6 As shown, the positioning groove can be a curved groove, which is used to position the cold-bent pipe that needs to be positioned.

[0030] During operation, this cold-bending pipe cutting device has positioning seats 111 on both sides of the clearance groove 9. The positioning seats 111 are provided with positioning grooves 12 for the cold-bending pipe to be cut. The positioning seats 111 are set on the cutting table 1 via a spacing adjustment mechanism, which facilitates the adjustment of the spacing between the positioning seats 111 to meet the positioning of cold-bending pipes of different specifications. The cutting table 1 is provided with a positioning mechanism 13 for positioning the cutting part. This positioning of both sides of the cutting position has a good fixing effect and avoids displacement during cutting, which would result in an uneven cut.

[0031] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
