Description

Technical Field

[0001] This utility model relates to the field of pipe cutting tools, and more specifically, to a highly safe pipe cutting tool. Background Technology

[0002] Stainless steel pipes are quite long, which is not conducive to warehousing or transportation. Therefore, after the pipes are produced, workers often cut them to the required length before warehousing or transportation. However, the existing equipment has certain problems in use and still needs to be continuously improved.

[0003] Existing publication number CN218639049U discloses a pipe cutting machine, including a base, a fixed plate fixedly connected to the upper part of one side of the base, and a worktable fixedly connected to the top of the base. A sliding groove is provided in the middle of one side of the top of the worktable, and a first threaded rod is rotatably connected within the sliding groove. The drive end of a dual-head motor rotates, and the threads of the second threaded rod are opposite in direction. With the cooperation of the dual-head motor, the first slider and the clamping plate can move closer or further apart, thus fixing the stainless steel pipe. The machine is simple to operate and improves production efficiency. After cutting, with the cooperation of a servo motor, the pipe can enter a grinding box. A stepper motor drives a rotating seat to rotate within the grinding box. Simultaneously, sandpaper inside the rotating seat grinds down the burrs on the stainless steel pipe, improving product quality and safety. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When cutting pipes with a cutting blade, the blade is exposed to the outside without any protective structure. This results in two problems: firstly, the exposed blade poses a safety hazard; secondly, the cutting blade generates flying cutting debris that can easily splash onto workers, creating a safety hazard and making the work environment dirty and messy.

[0005] Therefore, a highly safe pipe cutting tool is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pipe cutting tool with high safety to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-safety pipe cutting tool, comprising a cutting table, a connecting frame fixedly mounted on the upper surface of the cutting table, two second electric push rods symmetrically mounted on the top of the connecting frame, the output ends of the two second electric push rods being connected to a connecting plate, a first protective cover fixedly mounted on one side of the two connecting plates, a cutting machine connected to the bottom wall of the connecting plate via a moving component, a second protective cover fixedly mounted on the upper surface of the cutting table, a fixed seat fixedly mounted on the outer wall of the connecting plate, an elastic compression block fixedly mounted at the bottom end of the fixed seat, a receiving seat fixedly mounted on the outer wall of the second protective cover, a pressure sensor mounted on the receiving seat, and a signal controller electrically connected to the pressure sensor mounted on the upper surface of the cutting table and located on one side of the second protective cover.

[0008] Preferably, the moving component includes a fixed plate, a first threaded rod, and a first slider. Two fixed plates are symmetrically arranged on the bottom wall of the connecting plate. The two fixed plates are rotatably connected by a first threaded rod. The first slider is threadedly sleeved on the outer side of the first threaded rod. The cutting machine is bolted to the first slider.

[0009] Preferably, one end of the first threaded rod is connected to a servo motor that drives the first threaded rod, and the servo motor is mounted on the surface of the fixed plate by bolts.

[0010] Preferably, a first electric push rod is installed on each side of the connecting frame, and a first clamping block is connected to the output end of each of the two first electric push rods.

[0011] Preferably, a groove is provided on the upper surface of the cutting table, a second threaded rod is rotatably connected in the groove, a second slider is threadedly sleeved on the outer side of the second threaded rod, and an installation frame is installed on the top of the second slider.

[0012] Preferably, a third electric push rod is installed on both sides of the mounting frame, and a second clamping block is connected to the output end of each of the two third electric push rods. A rubber pad is connected to the opposite surface of each of the two second clamping blocks.

[0013] Preferably, a pointer is fixedly connected to both sides of the mounting frame, and a scale is provided on the upper surface of the connecting bracket below the pointer.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this highly safe pipe cutting tool can, on the one hand, be covered by a first protective cover and a second protective cover to prevent injury from accidental contact with the exposed cutting machine during operation. On the other hand, the first and second protective covers can also prevent flying debris from injuring workers and causing environmental mess during cutting. At the same time, the downward movement of the first protective cover causes the elastic extrusion block to compress the pressure sensor. After the pressure sensor detects the pressure, it controls the power supply of the cutting machine motor through the signal controller, thereby causing the cutting machine to rotate and cut the pipe. Thus, the cutting machine will only rotate and cut the pipe when the first and second protective covers are tightly closed, further improving the safety performance and practicality of the entire device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 4 The illustrated high-safety pipe cutting tool includes a cutting table 1. A connecting frame 2 is fixedly mounted on the upper surface of the cutting table 1. Two second electric push rods 5 are symmetrically arranged at the top of the connecting frame 2. The output ends of the two second electric push rods 5 are connected to a connecting plate 6. A first protective cover 7 is fixedly connected to one side of the two connecting plates 6. A cutting machine 11 is connected to the bottom wall of the connecting plate 6 through a moving component. A second protective cover 12 is fixedly mounted on the upper surface of the cutting table 1. A fixing seat 13 is fixedly mounted on the outer wall of the connecting plate 6. An elastic compression block 16 is fixedly mounted at the bottom end of the fixing seat 13. A receiving seat 14 is fixedly mounted on the outer wall of the second protective cover 12. A pressure sensor 15 is installed on the receiving seat 14. A signal controller 17 electrically connected to the pressure sensor 15 is installed on the upper surface of the cutting table 1 and located on one side of the second protective cover 12.

[0024] Specifically: When the first protective cover 7 moves down and closes with the second protective cover 12, the first protective cover 7 and the second protective cover 12 cover the cutting machine 11, preventing injury to personnel from accidental contact with the exposed cutting machine 11 during operation. On the other hand, covering the cutting machine 11 with the first protective cover 7 and the second protective cover 12 can also prevent flying debris from accidentally injuring workers and causing environmental mess during cutting. At the same time, the downward movement of the first protective cover 7 drives the elastic extrusion block 16 to extrude pressure sensor 15. After the pressure sensor 15 detects the pressure, it controls the motor power of the cutting machine 11 to turn on through the signal controller 17, thereby causing the cutting machine 11 to rotate and cut the pipe. In this way, the cutting machine 11 will only rotate to cut the pipe when the first protective cover 7 and the second protective cover 12 are tightly closed, further improving the safety performance of the entire device.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the moving component includes a fixed plate 8, a first threaded rod 9, and a first slider 10. Two fixed plates 8 are symmetrically arranged on the bottom wall of the connecting plate 6, and the first threaded rod 9 is rotatably connected between the two fixed plates 8. A servo motor that drives the first threaded rod 9 is connected to one end of the first threaded rod 9, and the servo motor is mounted on the surface of the fixed plate 8 by bolts. The first slider 10 is threaded on the outer side of the first threaded rod 9. The cutting machine 11 is bolted to the first slider 10. When the cutting machine 11 moves and cuts the pipe, the first threaded rod 9 is directly driven to rotate by the servo motor, and then the rotating first threaded rod 9 drives the first slider 10 to move the cutting machine 11, thereby cutting the pipe by the moving cutting machine 11.

[0028] In a preferred embodiment, a first electric push rod 3 is installed on both sides of the connecting frame 2, and a first clamping block 4 is connected to the output end of each of the two first electric push rods 3. A groove 18 is formed on the upper surface of the cutting table 1, and a second threaded rod 19 is rotatably connected within the groove 18. A second slider 20 is threaded onto the outer side of the second threaded rod 19, and a mounting frame 21 is installed at the top of the second slider 20. A third electric push rod 22 is installed on both sides of the mounting frame 21, and a second clamping block 23 is connected to the output end of each of the two third electric push rods 22. A rubber gasket is connected to the opposite face of each of the two second clamping blocks 23. A pointer 24 is fixedly connected to both sides of the mounting frame 21, and a scale 25 is provided on the upper surface of the connecting frame 2 below the pointer 24. During use... One end of the pipe can be placed between two second clamping blocks 23. Then, two third electric push rods 22 push the two second clamping blocks 23 toward the pipe and clamp and fix the pipe. At the same time, the second threaded rod 19 can be driven to rotate by a servo motor. The rotating second threaded rod 19 drives the second slider 20, the mounting frame 21 and the pipe end set on the mounting frame 21 to push. At the same time, the length of the pushed pipe can be known by the cooperation of the pointer 24 on the moving mounting frame 21 and the scale 25 on the cutting table 1, so as to facilitate the control of the cutting length of the pipe. Finally, the first clamping block 4 is pushed by two first electric push rods 3 to further clamp and fix the pipe, improving the stability of the pipe fixation when the cutting machine 11 cuts the pipe.

[0029] In this embodiment, the electric push rod, servo motor, cutting machine 11, pressure sensor 15, signal controller 17, etc. are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0030] The working process of this utility model is as follows: First, the pipe is clamped and fixed between two first clamping blocks 4. Then, the second electric push rod 5 pushes the first protective cover 7 and the elastic extrusion block 16 set on the first protective cover 7 to move downward. During the downward movement, the elastic extrusion block 16 approaches the pressure sensor 15 on the receiving seat 14 and squeezes the pressure sensor 15. When the first protective cover 7 and the second protective cover 12 are tightly closed, the power supply of the motor of the cutting machine 11 is turned on by the signal controller 17, so that the cutting machine 11 rotates and cuts the pipe. In this way, only when the first protective cover 7 and the second protective cover 12 are tightly closed, the cutting machine 11 rotates and cuts the pipe. Only when the two protective covers 12 are tightly closed will the cutting machine 11 rotate to cut the pipe, further improving the safety and practicality of the entire device. At the same time, the first protective cover 7 and the second protective cover 12 cover the cutting machine 11 to prevent injury from accidental contact by personnel when the cutting machine 11 is exposed to the outside. On the other hand, the first protective cover 7 and the second protective cover 12 cover the cutting machine 11 to prevent the flying debris during cutting from accidentally injuring workers and causing environmental mess. The above is the working principle of this highly safe pipe cutting tool.
