This utility model discloses a steel pipe cutting device with noise reduction function. This device absorbs the noise generated during the cutting process through the noise-absorbing box and sound-absorbing cotton, which will not affect the hearing of the workers and reduce noise pollution. This device does not require the worker to hold the cutting blade, reducing the difficulty of the work and improving work efficiency.

[0004] In the aforementioned patent, when processing steel pipes with smaller diameters, there will be a large gap between the steel pipe and the inlet and outlet of the steel pipe, causing noise to be transmitted directly from the gap to the outside of the noise reduction box, thereby reducing the noise reduction effect of the noise reduction box and its applicable range. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device with noise reduction function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pipe cutting device with noise reduction function, comprising: a noise-proof box, the left and right plates of the noise-proof box having inlets and outlets, fixed rods located on both sides of the inlets and outlets being horizontally fixed at both ends of the outer walls of the left and right plates of the noise-proof box, movable rods being horizontally slidable on the fixed rods, and connecting plates being vertically fixed at one end of each of the two movable rods facing each other, and a sound insulation plate sliding with the outer wall of the noise-proof box being bolted to the other side of the connecting plate, sound-absorbing cotton being fixed at both ends of one side of the sound insulation plate, a fixed frame located above the inlets and outlets being horizontally fixed on the outer walls of the left and right plates of the noise-proof box, a motor being fixed on the top surface of the fixed frame, a worm gear meshing with a worm wheel being fixed at the output end of the motor, threaded cylinders rotating with the fixed frame being horizontally fixed on both the front and rear walls of the worm wheel, threaded rods being threadedly connected to the threaded cylinders, and a connecting rod sliding with the fixed rods being vertically fixed at the end of the threaded rod away from the fixed frame, and one end of the connecting rod and the movable rod being fixed.

[0007] Furthermore, the noise reduction box has a door hinged to its front end, and a cylinder is vertically fixed at the center of the top surface of the noise reduction box. The movable end of the cylinder is fixed with a cutting device located inside the noise reduction box.

[0008] Furthermore, cylinders 2 are vertically fixed at both ends of the inner walls of the upper and lower plates of the noise reduction box. Cylinders 2 on the upper and lower sides are located on both sides of the inlet and outlet. A clamping plate is horizontally fixed at the movable end of cylinder 2. A rubber pad 1 is fixed on the side wall of the clamping plate away from cylinder 2. The center of the clamping plate, the rubber pad 1 and the inlet and outlet are located on the same vertical plane.

[0009] Furthermore, the fixed rod has a horizontally opening movable groove on the side near the noise reduction box that slides with the movable rod. The movable rod is slidably connected to the outer wall of the noise reduction box. The movable rod is fixed to the center of the side wall of the connecting plate. The connecting plate is slidably connected to the outer wall of the noise reduction box.

[0010] Furthermore, the bolt passes through the connecting plate and the sound insulation plate for threaded connection, the sound insulation plate and the outer wall of the noise reduction box are slidably connected, and a semi-circular groove is opened on the side of the sound insulation plate near the inlet and outlet. A rubber pad II is fixed in the semi-circular groove, and the two ends of the rubber pad II are respectively fixed to the sound-absorbing cotton.

[0011] Furthermore, the two ends of the worm are rotatably connected within the upper and lower plates of the fixed frame. The worm is located outside the worm wheel, the worm wheel is located inside the fixed frame, the connecting rod is located outside the fixed frame, and the top surface of the fixed rod is horizontally provided with a strip groove that is slidably connected to the connecting rod and communicates with the movable groove.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. This utility model solves the problem of noise reduction by bolting a sound insulation plate with rubber pads and sound-absorbing cotton onto a connecting plate according to the diameter of the threaded pipe to be processed. The threaded pipe is then placed between the inlet / outlet and between the sound insulation plate. The motor is then started, driving the worm gear to rotate on the fixed frame. The worm gear drives the worm wheel to rotate, causing the threaded cylinder to rotate within the fixed frame. The threaded cylinder causes the threaded rod to move horizontally towards the worm wheel. The threaded rod drives the connecting rod to slide in the slotted groove, which in turn drives the movable rod to slide in the movable groove. The movable rod drives the connecting plate, which, through bolts, causes the sound insulation plate to slide on the noise-proof box and move towards the threaded steel. The sound-absorbing cotton on the sound insulation plate comes into contact and is compressed, while the rubber pads enclose the threaded pipe. The motor is then turned off, and the cylinder and cutting equipment are started to cut the threaded pipe. This method solves the problem of large gaps between the steel pipe and the inlet / outlet when processing smaller diameter steel pipes, causing noise to propagate directly to the outside of the noise-proof box and reducing its noise reduction effect. This method improves the noise reduction effect and expands its applicability. 2. Before adjusting the position of the sound insulation board, the second cylinder is started first. The output end of the second cylinder drives the clamping plate to move. The clamping plate fixes the rubber pads to the threaded tube. At this time, the center of the threaded tube and the center of the inlet and outlet are on the same horizontal line, and the threaded tube is located between the two sound insulation boards. In addition to fixing the threaded tube during the cutting process, it also makes it easier for the rubber pads on the sound insulation board to surround the threaded tube.

[0014] 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.

[0015] Please see Figures 1-4This utility model provides a technical solution: a pipe cutting device with noise reduction function, comprising: a noise-proof box 1, a door 2 hinged to the front end of the noise-proof box 1, a cylinder 3 vertically fixed at the center of the top surface of the noise-proof box 1, a cutting device 8 located inside the noise-proof box 1 fixed at the movable end of the cylinder 3, inlets and outlets 9 on the left and right plates of the noise-proof box 1, and cylinders 10 vertically fixed at both ends of the inner walls of the upper and lower plates of the noise-proof box 1, with the cylinders 10 on the upper and lower sides located on both sides of the inlets and outlets 9, and a clamping plate 11 horizontally fixed at the movable end of the cylinder 10, the clamping plate 11 clamping and fixing the threaded pipe, and a rubber pad 12 fixed on the side wall of the clamping plate 11 away from the cylinder 10, the rubber pad 12 improving the protection of the threaded pipe and alleviating the friction between the threaded pipe and the clamping plate 11 during the cutting process. The collision is prevented because the centers of the clamping plate 11, rubber pad 12, and inlet / outlet 9 are located on the same vertical plane, ensuring good fixation of the threaded pipe. The left and right outer walls of the noise-reducing box 1 are horizontally fixed with fixing rods 4 located on both sides of the inlet / outlet 9. Movable rods 20 slide horizontally on the fixing rods 4. Connecting plates 21 are vertically fixed to one end of each of the two movable rods 20 facing each other. A movable groove 13 is horizontally opened on the side of the fixing rod 4 closest to the noise-reducing box 1, allowing it to slide with the movable rods 20. The movable rods 20 are slidably connected to the outer wall of the noise-reducing box 1. The movable rods 20 are fixed to the center of the side wall of the connecting plate 21. The connecting plate 21 is slidably connected to the outer wall of the noise-reducing box 1. A sound-insulating plate 7, which slides with the outer wall of the noise-reducing box 1, is connected to the other side of the connecting plate 21 via bolts 22. The diameter of the threaded pipe to be processed is determined according to the requirements of the noise-reducing box 1. The appropriate sound insulation panel 7 is replaced by removing bolt 22. The sound insulation panel 7 is slidably connected to the noise reduction box 1. The sound insulation panel 7 can seal the gap between the threaded pipe and the inlet / outlet 9, preventing noise from passing through the gap to the outside of the noise reduction box 1. The sound insulation panel 7 plays a role in noise reduction. Sound-absorbing cotton 24 is fixed at both ends on one side of the sound insulation panel 7. When the two sound insulation panels 7 are in contact, they are in contact through the sound-absorbing cotton 24, which can absorb noise to a certain extent and improve the noise reduction effect. Bolt 22 passes through the connecting plate 21 and is threadedly connected to the sound insulation panel 7. The sound insulation panel 7 is slidably connected to the outer wall of the noise reduction box 1. A semi-circular groove is opened on the side of the sound insulation panel 7 near the inlet / outlet 9. A rubber pad 23 is fixed in the semi-circular groove. The rubber pad 23 plays a role in protecting the threaded pipe and can also alleviate noise. During the cutting process, the vibration between the threaded pipe and the sound insulation plate 7 reduces noise generation and has a certain noise reduction effect. The two ends of the rubber pad 23 are fixed to the sound-absorbing cotton 24 respectively. The fixed frame 6 located above the inlet and outlet 9 is horizontally fixed on the outer wall of the left and right plates of the noise reduction box 1. The motor 18 is fixed on the top surface of the fixed frame 6. The output end of the motor 18 is fixed with a worm 19 that meshes with the worm gear 17. The front and rear walls of the worm gear 17 are both horizontally fixed with threaded cylinders 16 that rotate with the fixed frame 6. The threaded cylinder 16 is threadedly connected to a threaded rod 15. The end of the threaded rod 15 away from the fixed frame 6 is vertically fixed with a connecting rod 5 that slides with the fixed rod 4. The two ends of the worm 19 are rotatably connected in the upper and lower plates of the fixed frame 6. The worm 19 is located outside the worm gear 17, and the worm gear 17 is located inside the fixed frame 6.The connecting rod 5 is located outside the fixed frame 6. The top surface of the fixed rod 4 has a horizontally opening strip-shaped groove 14 that slides through the connecting rod 5 and communicates with the movable groove 13. One end of the connecting rod 5 and the movable rod 20 are fixed.

[0016] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-4 According to the diameter of the threaded pipe to be processed, the corresponding sound insulation plate 7 with rubber pad 23 and sound-absorbing cotton 24 is installed on the connecting plate 21 by bolts 22. Then, the threaded pipe is placed between the inlet and outlet 9. The cylinder 10 is started. The output end of the cylinder 10 drives the clamping plate 11 to fix the rubber pad 12 to the threaded pipe. At this time, the center of the threaded pipe and the center of the inlet and outlet 9 are on the same horizontal line. Then, the motor 18 is started. The output end of the motor 18 drives the worm gear 19 to rotate on the fixed frame 6. The worm gear 19 drives the worm wheel 17 to rotate, thereby causing the threaded cylinder 16 to rotate in the fixed frame 6. The threaded cylinder 16 causes the threaded rod 15 to move horizontally to one side of the worm wheel 17. The connecting rod 5 slides within the strip groove 14, and the connecting rod 5 drives the movable rod 20 to slide within the movable groove 13. The movable rod 20 drives the connecting plate 21 to slide the sound insulation plate 7 on the noise reduction box 1 via the bolt 22 and move it towards the threaded steel side. The sound-absorbing cotton 24 on the sound insulation plate 7 comes into contact and is squeezed, and the rubber pad 23 surrounds the threaded pipe. The motor 18 is turned off, and then the cylinder 3 and the cutting device 8 are started to cut the threaded pipe. This solves the problem that when processing steel pipes with smaller diameters, there will be a large gap between the steel pipe and the inlet / outlet 9, causing noise to be directly transmitted to the outside of the noise reduction box 1 through the gap, which will reduce the noise reduction effect of the noise reduction box 1. This improves the noise reduction effect and expands the range of application.

[0017] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
