Description

Technical Field

[0001] This application relates to the field of automatic pipe cutting machine technology, and more particularly to an automatic pipe cutting machine. Background Technology

[0002] An automatic pipe cutting machine is a device that can automatically cut pipes, mainly used for cutting metal pipes. Through mechatronics design, it achieves a high degree of automation, reducing manual intervention and improving production efficiency.

[0003] A published patent document with announcement number CN210435457U describes a steel pipe cutting machine. In this patent, a motor drives the cutter to rotate, and a cylinder lifts the active end while simultaneously moving the driven end downward. The cutter moves downward with the driven end and is used to cut the steel pipe. When cutting the steel pipe, the active end is lifted upward and the driven end moves downward through the hinge structure between the extension rod and the protrusion and the hinge structure between the lower protrusion and the placement groove. This reduces the amount of material used in the design and facilitates the installation of the machine. However, the device does not have a clamp to hold and fix the steel pipe during use, which makes the steel pipe prone to movement during the cutting process, potentially causing accidents or a decrease in accuracy.

[0010] By adopting the above technical solution, teeth are provided on the inner wall of the V-shaped clamp to increase the friction between the V-shaped clamp and the steel pipe, thereby improving the stability of the device during clamping.

[0011] As a preferred technical solution of this application, a support frame is fixedly installed on the upper surface of the cutting table on one side of the cutting mechanism, and the top of the support frame is in contact with the bottom of the placement tube.

[0013] As a preferred technical solution of this application, a cutting groove is provided through the top of the placement tube, and the cutting groove extends downward into the interior of the support frame.

[0014] By adopting the above technical solution, the cutting groove is opened to ensure that the cutting mechanism will not damage the support frame and the placement tube during cutting.

[0015] As a preferred technical solution of this application, the cutting mechanism includes a piston rod and a bracket. The top of the piston rod and the bracket are hinged to the same adjusting plate. The end of the adjusting plate near the placement tube is circular and a motor is fixedly installed inside it. A slice is fixedly installed at the output end of the motor.

[0016] By adopting the above technical solution, the position of motor one is adjusted through the cooperation between piston rod, bracket and adjusting plate, thereby driving the slicer to move downward to cut the steel pipe.

[0017] As a preferred technical solution of this application, the slice and the cutting groove are on the same vertical plane, and the width of the cutting groove is greater than the thickness of the slice.

A motor 11 for driving the threaded rod 7 to rotate is fixedly installed on the top of the positioning frame 6. A moving plate 8 is threadedly connected to the outer surface of the threaded rod 7. A V-shaped clamping block 9 is fixedly connected to the center of the lower surface of the moving plate 8. In use, a round hole is made on the outer wall of the positioning plate 3 to insert a steel pipe so that the steel pipe can be accurately placed on the placement tube 4. The motor 11 is started to drive the threaded rod 7 to rotate. The position of the V-shaped clamping block 9 is adjusted by the cooperation between the threaded rod 7 and the moving plate 8, so that the V-shaped clamping block 9 moves downward to clamp the steel pipe, so as to fix the steel pipe on the placement tube 4 and ensure that the steel pipe will not shake or shift its position during the subsequent cutting process, thus avoiding accidents or a decrease in accuracy.

[0030] In this embodiment, as Figure 2 As shown, a guide rod 12 is slidably inserted inside the movable plate 8. The guide rod 12 is fixedly connected to the positioning frame 6, and the guide rod 12 and the threaded rod 7 are symmetrically arranged about the V-shaped clamp 9. In use, the guide rod 12 limits the movement trajectory of the movable plate 8 to prevent the movable plate 8 from shaking during movement and to ensure the stability of the V-shaped clamp 9 during movement.

[0031] In this embodiment, as Figure 2 As shown, the inner walls on both sides of the V-shaped clamping block 9 are provided with several teeth 10. In use, the teeth 10 on the inner walls of the V-shaped clamping block 9 are used to increase the friction between the V-shaped clamping block 9 and the steel pipe, thereby improving the stability of the device during clamping.

[0032] In this embodiment, as Figure 1 As shown, a support frame 5 is fixedly installed on the upper surface of the cutting table 1 on one side of the cutting mechanism 2. The top of the support frame 5 is in contact with the bottom of the placement tube 4. During use, the support frame 5 supports the placement tube 4 to prevent the front end of the placement tube 4 from falling due to gravity and to ensure that the placement tube 4 can always be in a parallel state.

[0033] In this embodiment, as Figure 4 As shown, a cutting groove 13 is provided through the top of the placement tube 4, and the cutting groove 13 extends downward into the interior of the support frame 5. In use, the cutting groove 13 ensures that the cutting mechanism 2 will not damage the support frame 5 and the placement tube 4 when cutting.

[0034] In this embodiment, as Figure 3As shown, the cutting mechanism 2 includes a piston rod 21 and a bracket 22. The top of the piston rod 21 and the bracket 22 are hinged to the same adjusting plate 23. The end of the adjusting plate 23 near the placement tube 4 is circular and a motor 24 is fixedly installed inside it. A slice 25 is fixedly installed at the output end of the motor 24. In use, the position of the motor 24 is adjusted by the cooperation between the piston rod 21, the bracket 22 and the adjusting plate 23, thereby driving the slice 25 to move downward to cut the steel pipe.

[0035] In this embodiment, as Figure 3 and 4 As shown, the slice 25 and the cutting groove 13 are on the same vertical plane, and the width of the cutting groove 13 is greater than the thickness of the slice 25. During use, ensure that the slice 25 can be accurately inserted into the inside of the cutting groove 13 without any offset or collision.
