Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a pipe cutting device for automotive steel pipes. Background Technology

[0002] Automotive steel pipes are steel pipes used in automobile manufacturing. During use, automotive steel pipes are cut into different lengths and angles according to requirements. Therefore, a flexible and adjustable cutting device is needed to cut the automotive steel pipes so that the length of the steel pipe can be adapted to different lengths for installation and assembly.

[0003] In existing technologies, conventional cutting devices use clamps to position pipes during the cutting process. However, conventional clamps have poor applicability. Different pipes vary in shape, specifications, and cutting requirements. Some pipes require cutting at specific angles, and conventional clamps cannot meet the needs of cutting at different angles. They cannot flexibly adjust to the required specific angle quickly and accurately according to the actual cutting needs of the pipes, thus failing to meet diverse cutting requirements. Therefore, it is necessary to improve the pipe cutting device for steel pipes to solve the above problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a steel pipe cutting device, including a workbench 1, a sliding seat 21 slidably connected to the workbench 1, a rotating shaft 22 rotatably connected to the sliding seat 21, a pad 23 fixedly connected to the rotating shaft 22, a support plate 24 fixedly connected to the pad 23, an electric telescopic rod 25 fixedly connected to the support plate 24, a connecting plate 26 fixedly connected to the electric telescopic rod 25, a rubber pad 27 fixedly connected to the connecting plate 26, a limiting rod 28 fixedly connected to the connecting plate 26, an adjustment assembly mounted on the sliding seat 21, and a cutting assembly mounted on the workbench 1. The limiting rod 28 is slidably connected to the support plate 24. The adjustment assembly can drive the sliding seat 21 to slide and can drive the pad 23 to rotate, placing the pipe fitting on the pad 23. On the upper part, a tapered groove is provided on the pad 23. The pipe is placed inside the tapered groove and initially positioned by the groove. The electric telescopic rod 25 pushes the connecting plate 26. The connecting plate 26 abuts against the pipe through the rubber pad 27, positioning the pipe on the surface of the pad 23. The lateral position of the sliding seat 21 can be adjusted by the adjustment component, so that the lateral position of the pipe can be adjusted together. At the same time, the tilt angle of the pipe can be adjusted by the adjustment component, so that the pipe can be cut at a suitable angle. After the pipe is positioned, the hanging part can be cut by the cutting component. The worktable 1 has a sliding groove at the corresponding position of the sliding seat 21, and the sliding seat 21 slides inside the sliding groove. The sliding groove limits the sliding seat 21, so that the sliding seat 21 can only slide in a straight line inside the sliding groove, avoiding tilting and jamming, and ensuring smooth movement.

[0023] Please see Figures 1-2In this embodiment, the adjustment assembly includes a threaded rod 31 rotatably connected to the workbench 1, a positioning block 32 fixedly connected to the sliding seat 21, a worm gear 33 rotatably connected to the positioning block 32, and a worm wheel 34 meshing with the worm gear 33. The worm wheel 34 is fixedly connected to the rotating shaft 22. The sliding seat 21 is threadedly connected to the threaded rod 31. The rotation of the threaded rod 31 drives the sliding seat 21 to slide. Through the self-locking between the worm wheel 34 and the worm gear 33, the angle of the pipe can be adjusted to a suitable position and then automatically positioned to avoid the pipe from loosening during cutting due to self-rotation.

[0024] Please see Figure 1 , Figures 4-5 In this embodiment, the cutting assembly includes an electric guide rail 41 fixedly connected to the top of the workbench 1, a movable plate 42 slidably connected to the electric guide rail 41, a drive motor 43 fixedly connected to the movable plate 42, a rotating disk 44 fixedly connected to the output end of the drive motor 43, a positioning shaft 45 fixedly connected to the rotating disk 44, a positioning component mounted on the positioning shaft 45, and a cutting blade 46 mounted on the positioning shaft 45. The drive motor 43 drives the cutting blade 46 to rotate and contact the pipe fitting through the rotating disk 44 and the positioning shaft 45. The position of the cutting blade 46 can be controlled by the electric guide rail 41. The electric guide rail 41 is a guide rail device that achieves precise control through motor drive. It is mainly used for high-precision linear motion control in the field of industrial automation for automatic cutting. The cutting blade 46 has a through-hole adapted to the positioning shaft 45. The cutting blade 46 is mounted on the positioning shaft 45 through the through hole. The through hole and the positioning shaft 45 cooperate to allow the positioning shaft 45 to rotate synchronously with the cutting blade 46, preventing the cutting blade 46 from rotating on its own or becoming loose. The positioning assembly includes a clamping plate 51 slidably connected to the positioning shaft 45, a lever plate 52 fixedly connected to the clamping plate 51, and a spring 53 fixedly connected between the clamping plate 51 and the positioning shaft 45. The positioning assembly allows for quick disassembly of the cutting blade 46, enabling quick replacement of the cutting blade 46. The positioning shaft 45 has matching grooves at corresponding positions on the clamping plate 51 and the lever plate 52, and the clamping plate 51 and the lever plate 52 slide within their respective grooves. The grooves limit the lever plate 52, preventing it from sliding too much and disengaging. The lever plate 52 is positioned, thereby positioning the clamping plate 51.

[0025] During operation, the pipe fitting is placed in the conical groove of the pad 23 for initial positioning. The electric telescopic rod 25 extends and retracts, driving the connecting plate 26 to be limited by the limiting rod 28. The connecting plate 26 presses the pipe fitting against the rubber pad 27, and the rubber pads 27 on both sides simultaneously position the pipe fitting. Then, the worm gear 33 is turned to drive the worm wheel 34, which in turn drives the rotating shaft 22. The rotating shaft 22 drives the pad 23, thereby adjusting the angle of the positioned pipe fitting through the pad 23. Finally, the threaded rod 31 is turned to drive the sliding seat 21 to slide. Adjust the position of the pipe and then align the pipe fitting with the moving path of the cutting blade 46. Drive the motor 43 to drive the rotating disk 44, the rotating disk 44 to drive the positioning shaft 45, and the positioning shaft 45 to drive the cutting blade 46. The cutting blade 46 cuts the pipe fitting. When the cutting blade 46 is damaged, the push plate 52 can be pushed to drive the clamping plate 51. The clamping plate 51 slides to compress the spring 53. The spring 53 is used for the automatic reset of the clamping plate 51. The clamping plate 51 slides into the groove, and the clamping plate 51 disengages from the cutting blade 46, so that the cutting blade 46 can be removed from the positioning shaft 45 for replacement.

[0026] Through the above steps, the position of the movable pipe can be adjusted, and the positioned pipe can be tilted to a suitable angle, thereby enabling cutting at different angles and cutting the pipe into openings at different angles. This solves the problem that conventional clamps cannot meet diverse cutting requirements.
