Description

Technical Field

[0001] This application relates to the field of pipe cutting technology, specifically to a pipe cutting device. Background Technology

[0002] Currently, pipe cutting methods include sawing, abrasive wheel cutting, gas cutting, or laser cutting. Among these, abrasive wheel cutting is the most commonly used method. It is more convenient and labor-saving than sawing, and less expensive than gas cutting or laser cutting. However, abrasive wheel cutting uses an abrasive wheel to cut pipes, which generates a large number of metal sparks and fumes containing fine particles. The flying sparks, slag, and particles may enter the operator's eyes, and long-term inhalation of the fumes can lead to respiratory diseases, greatly affecting human health. Utility Model Content

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] See Figures 1 to 6 Further explanation of this application:

[0032] Combination Figure 1 and Figure 2 The pipe cutting device includes a frame 1 with a fixed support at the bottom, a cutting blade 4 mounted on the top of the frame 1, and the cutting blade 4 being movable along the z-axis. The cutting blade 4 is moved along the z-axis by a cylinder or screw mechanism, and can be rotated by a motor. A support mechanism 3 is provided at the bottom of the cutting blade 4, mounted on the frame 1, for supporting and fixing the pipe fitting 100. A smoke removal mechanism 2 is provided on the frame 1 to purify the fumes generated during pipe cutting and to prevent metal particles generated during cutting from splashing onto the outside of the frame 1, facilitating cleaning.

[0033] Combination Figure 2The smoke removal mechanism 2 includes a filter box 24, a transparent partition box 21, and a blower component 23. The transparent partition box 21 is located outside the cutting blade 4 and is used to collect the smoke generated during cutting. The top of the transparent partition box 21 is conical to facilitate the collection of smoke, and the transparent partition box 21 is made of transparent material for easy observation. The blower component 23 connects the filter box 24 and the transparent partition box 21 through a connecting pipe 22, and is used to provide negative pressure inside the transparent partition box 21 to extract the smoke inside the transparent partition box 21 and transport it out. The filter box 24 has a placement opening 5 on the transparent partition box 21. The pipe 100 passes through the placement opening 5 and is supported and fixed by the support mechanism 3. The filter box 24 is used to filter impurities and odors in the flue gas. The connecting pipe 22 can be a flexible hose, and the blower component 23 can be a blower. This not only prevents the operator from inhaling the flue gas generated during cutting and polluting the surrounding air, but also prevents the high-temperature metal sparks generated during cutting from splashing onto the body, thereby maintaining the air quality in the environment and reducing harm to the human body.

[0034] Combination Figure 4 In this embodiment, the filter box 24 is provided with a liquid storage chamber and a filter layer from bottom to top. The liquid storage chamber is filled with a medium, which can be water. An aeration device 7 is provided at the bottom of the liquid storage chamber to ensure that the flue gas is in full contact with the medium. The aeration device 7 is connected to the blower component 23. An exhaust port 11 is provided at the top of the filter box 24. The filter layer includes a filter screen 8 and at least one adsorption layer 9, which can be filled with activated carbon. The blower component 23 sends the flue gas into the filter box 24. The aeration device 7 enables the flue gas to fully contact the medium in the liquid storage chamber, removing particulate matter from the flue gas. The flue gas after preliminary filtration then flows through the filter screen 8 and the adsorption layer 9 for secondary filtration, removing remaining impurities and odors from the flue gas. Finally, it is discharged through the exhaust port 11. This method can remove impurities and odors from the flue gas and avoids the need for multiple filter layers, thereby greatly reducing airflow resistance.

[0035] In some embodiments, the exhaust port 11 is provided with an exhaust component 10, which can guide the flue gas in the filter box 24 through the filter layer, prevent the flue gas from accumulating in the filter box 24, and improve the filtration effect.

[0036] Combination Figure 3The support mechanism 3 includes a plurality of support plates 31 disposed inside the transparent compartment 21, and at least one locking component 32 disposed on both sides of the outside of the transparent compartment 21. The support plates 31 are used to support the pipe 100 so that the cutting blade 4 can cut the pipe 100. The locking component 32 is used to clamp and fix the pipe 100 to prevent displacement during cutting and thus avoid affecting the cutting effect. The support plates 31 can slide along the x-axis to adjust the support position. The support plates 31 can be slidably connected to the frame 1 via a slide rail.

[0037] Combination Figure 5 and Figure 6 The locking component 32 includes a support block 321 and a pair of pistons 322, as well as a bidirectional screw 323 for driving the pistons 322 to move; the bidirectional screw 323 and the pistons 322 form a clamping component; one end of the bidirectional screw 323 is provided with a drive handle 324, which is used to drive the bidirectional screw 323 to rotate; the support block 321 is provided with a receiving cavity 320 coaxial with the placement port 5, and a through hole perpendicular to the axis of the receiving cavity 320; the bidirectional screw... 323 is rotatably connected to the support block 321 inside the through hole. The piston 322 is sleeved on the outside of the bidirectional screw 323 and located on both sides of the receiving cavity. It can move along the y-axis direction inside the through hole to clamp the pipe fitting 100. The bidirectional screw 323 is driven to rotate by the drive handle 324. The piston 322 can move synchronously towards or away from each other along the axial direction (y-axis direction) of the bidirectional screw 323, thereby clamping or releasing the pipe fitting 100 in the receiving cavity 320.

[0038] Combination Figure 1 In one embodiment, a telescopic component 6 is provided between the transparent compartment 21 and the frame 1. The telescopic component 6 can be a hydraulic telescopic rod or a pneumatic telescopic rod. The bottom of the transparent compartment 21 is provided with an opening 20, which allows some external air to enter the transparent compartment 21 through the opening 20. The transparent compartment 21 is rotatably connected to the frame 1, and the telescopic component 6 can extend and retract to open or close the transparent compartment 21.

[0039] The transparent compartment 21 has a liquid inlet 12 on one side and a liquid outlet 13 at the bottom, which facilitates the replacement of the medium in the liquid storage chamber.
