Description

Technical Field

[0001] This utility model belongs to the technical field of cutting devices for the production of pressure pipeline fittings, and specifically relates to a cutting device for the production of pressure pipeline fittings. Background Technology

[0002] In industrial piping systems, pressure pipelines are key components for transporting fluid media, and their processing quality directly affects the safety and reliability of the system. Currently, during the use of pressure pipeline fittings, valves or pressure gauges need to be installed on the pipeline. Therefore, a section of the pressure pipeline needs to be cut in the middle to leave space for the valve or pressure gauge installation. The existing cutting process directly uses a cutting blade to first cut an opening, and then cuts a section of pipeline according to the length required for the installation of the valve or pressure gauge. After the cutting device completes the pipeline cutting, it often faces residual debris inside and outside the pipeline. External debris is cleaned by wiping, but the debris remaining on the inner wall affects the normal operation of the pressure pipeline and can cause pressure pump blockage. In the existing technology, although some cutting equipment is equipped with a debris collection structure, it mostly only collects external debris generated during the cutting process and lacks an effective cleaning solution for residual debris inside the pipeline. Utility Model Content

[0003] The purpose of this invention is to provide a cutting device for the production of pressure pipeline fittings. The device uses a cutting component to cut the main body of the pressure pipeline. After cutting, the debris collection component is adjusted to make it tightly abut against the cut of the pressure pipeline. The debris collection component is then activated to suck out and collect the debris and dust remaining inside the pressure pipeline from the cut. This solves the problem of cleaning up residual debris inside the pressure pipeline after cutting, reducing the inefficiency and pollution risk of manual removal.

[0004] The specific technical solution adopted by this utility model is as follows:

[0006] The cutting assembly includes a drive shaft movably mounted on the frame, with two cutting blades detachably mounted at both ends of the drive shaft. The distance between the two cutting blades is adjustable. The debris collection assembly includes a collection tube located directly above the cutting blades. The collection tube has telescopic tubes at both ends, and the ends of the telescopic tubes are connected to wide-mouth tubes. The distance between the ends of the two wide-mouth tubes is adapted to the distance between the two cutting blades.

[0007] Furthermore, the cutting assembly also includes a drive motor mounted on a frame, which is also provided with two meshing transmission gears. A driven gear is provided on the drive shaft. The output end of the drive motor passes through the frame and is connected to one of the transmission gears, while the other transmission gear meshes with the driven gear.

[0008] Furthermore, the debris collection assembly also includes an air pump installed on the frame, the air pump inlet being connected to an air extraction pipe, and the air extraction pipe communicating with the collection pipe.

[0009] Furthermore, the inner wall of the wide-mouth pipe is inclined, and a debris collection bucket and a filter are installed on the exhaust pipe, with the lower end of the debris collection bucket installed.

[0010] Furthermore, the drive shaft has threaded holes arranged in an equally spaced array at both ends, and the cutting blade is mounted on the end frame of the drive shaft by bolts that fit into the threaded holes.

[0011] Furthermore, the frame is provided with two handles, one of which is located directly below the other, and a first switch and a second switch are installed on the upper handle.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4 As shown, a cutting device for the production of pressure pipe fittings includes a frame 1, on which a cutting assembly and a debris collection assembly are installed.

[0023] The cutting assembly includes a drive shaft 2 movably mounted on the frame 1. Two cutting blades 3 are detachably mounted at both ends of the drive shaft 2. The distance between the two cutting blades 3 is adjustable. The debris collection assembly includes a collection pipe 4 located directly above the cutting blades 3. Telescopic pipes 5 are provided at both ends of the collection pipe 4. Wide-mouth pipes 6 are connected to the ends of the telescopic pipes 5. The distance between the ends of the two wide-mouth pipes 6 is adapted to the distance between the two cutting blades 3.

[0024] In use, first fix the pressure pipe body 17 on the bracket. Adjust the distance between the cutting blades 3 at both ends of the drive shaft 2 according to the cutting requirements. At the same time, adjust the position of the wide-mouth tube 6 in the debris collection assembly through the telescopic tube 5 so that the distance between the ends of the two wide-mouth tubes 6 matches the distance between the cutting blades 3, ensuring that the collection range covers the cutting area. Then, start the cutting assembly to drive the drive shaft 2 to rotate. The cutting assembly moves towards the fixed pressure pipe body 17 to cut. The two cutting blades 3 rotate synchronously to achieve symmetrical cutting. After the cutting is completed, the collection assembly is started. The wide-mouth tube 6 is kept in alignment with the cutting area through the telescopic tube 5. After the cutting is completed, the end of the wide-mouth tube 6 of the debris collection assembly is tightly abutted against the cut of the pressure pipe body 17. The seal is increased by adjusting the telescopic tube 5. The debris collection assembly is started to suck out and collect the debris and dust remaining inside the pressure pipe body 17 from the cut, thereby solving the problem of cleaning the debris remaining inside the pressure pipe body 17 after cutting and reducing the inefficiency and pollution risk of manual removal.

[0025] like Figure 1 , Figure 2 , Figure 3As shown, the cutting assembly also includes a drive motor 7 mounted on the frame 1. The frame 1 is also provided with two meshing transmission gears 8. The drive shaft 2 is provided with a driven gear 9. The output end of the drive motor 7 passes through the frame 1 and is connected to one of the transmission gears 8. The other transmission gear 8 meshes with the driven gear 9. When in use, the drive motor 7 is started, and the drive motor 7 drives the transmission gear 8 connected to it to rotate. The transmission gear 8 drives the driven gear 9 to rotate, which in turn drives the cutting blade 3 to rotate synchronously, cutting the pressure pipe body 17 fixed on the bracket.

[0026] like Figure 1 , Figure 2 , Figure 4 As shown, the debris collection assembly also includes an air pump 10 installed on the frame 1. The air pump 10 has an air inlet connected to an air extraction pipe 11, which is connected to the collection pipe 4. When in use, the air pump 10 starts and forms a negative pressure in the air extraction pipe 11. This negative pressure is transmitted to the wide-mouth pipe 6 through the collection pipe 4, which is connected to the air extraction pipe 11.

[0027] like Figure 1 As shown, the inner wall of the wide-mouth pipe 6 is inclined. A debris collection bucket 13 and a filter 14 are installed on the exhaust pipe 11. The lower end of the debris collection bucket 13 is installed. When in use, the inner wall of the wide-mouth pipe 6 is inclined. When cutting, the debris splashes onto the inclined wall and then gathers along the slope. With the help of negative pressure airflow, it moves towards the exhaust pipe 11. The debris and dust generated by cutting gather on the inclined inner wall of the wide-mouth pipe 6 under the action of airflow and then enter the debris collection bucket 13 through the exhaust pipe 11. Larger debris particles settle at the bottom of the debris collection bucket 13 due to gravity. Fine dust is intercepted when it passes through the filter 14 with the airflow. The purified air is discharged by the air pump 10.

[0028] like Figure 1 , Figure 3 As shown, the drive shaft 2 has threaded holes arranged in an equally spaced array at both ends. The cutting blade 3 is installed on the end frame 1 of the drive shaft 2 by bolts that fit into the threaded holes. When the cutting blade 3 needs to be replaced, the old cutting blade 3 can be removed by unscrewing the bolts. After replacing the new cutting blade 3, it can be re-fixed to the corresponding threaded hole to complete the replacement of the cutting blade 3.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown, the frame 1 is equipped with two handles 12, one handle 12 is located directly below the other handle 12, and the upper handle 12 is equipped with a first switch 15 and a second switch 16. When in use, the upper and lower handles 12 provide a stable grip support point, and the operator can apply force by pushing the cutting component downward to apply cutting force. At the same time, the upper handle 12 integrates the first switch 15 and the second switch 16, which makes it convenient for the operator to control the start and stop of the equipment and switch functions with one hand.

[0030] like Figure 1 , Figure 4 As shown, the first switch 15 is electrically connected to the drive motor 7, and the second switch 16 is electrically connected to the air pump 10. In use, the first switch 15 and the drive motor 7 form an independent control circuit. When the second switch 16 is pressed, the circuit is turned on, the drive motor 7 starts, and the cutting operation is realized. When the switch is released, the circuit is turned off, the cutting action stops immediately, and thus the safety is improved.

[0031] The working principle of this utility model is as follows: In use, the pressure pipe body 17 is first fixed on the bracket. The distance between the cutting blades 3 at both ends of the drive shaft 2 is adjusted according to the cutting requirements. At the same time, the position of the wide-mouth tube 6 in the debris collection component is adjusted through the telescopic tube 5 so that the distance between the ends of the two wide-mouth tubes 6 matches the distance between the cutting blades 3, ensuring that the collection range covers the cutting area. Then, the cutting component is started to drive the drive shaft 2 to rotate. The cutting component moves towards the fixed pressure pipe body 17 to cut. The two cutting blades 3 rotate synchronously to achieve symmetrical cutting. After the cutting is completed, the collection component is started. The wide-mouth tube 6 is kept in place with the cutting area through the telescopic tube 5. After the cutting is completed, the end of the wide-mouth tube 6 of the debris collection component is tightly abutted against the cut of the pressure pipe body 17. The seal is increased by adjusting the telescopic tube 5. The debris collection component is started to suck out and collect the debris and dust remaining inside the pressure pipe body 17 from the cut, thereby solving the problem of cleaning the debris remaining inside the pressure pipe body 17 after cutting and reducing the inefficiency and pollution risk of manual removal.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
