Description

Technical Field

[0001] The present invention relates to the technical field of flange pipe joint processing technology, and particularly relates to a flange pipe joint processing device and method. Background Art

[0002] A flange joint is a pipe connector composed of a flange plate and a pipe welded together. The flange joint can effectively compensate and relieve the pipe and blind flange thrust, and is also convenient for the installation, maintenance and replacement of water pumps, valves and pipes, etc. It is indeed the most ideal supporting product in the pipeline installation and operation industry.

[0003] The document with the publication number CN114670024A points out that when the existing processing device is in use, 1. it cannot automatically process around the flange pipe, and the staff needs to continuously adjust the angle of the device or the flange pipe; 2. a large amount of iron filings and dust will be generated, which will affect the environment of the production workshop, and there is no guarantee for the physical safety of the staff working in the workshop for a long time, and the safety of the device is not high.

[0004] By placing the joint of the flange pipe upward in the middle of the rotating plate and processing the joint of the flange pipe, the flange pipe can rotate on the rotating plate. When the staff operates, there is no need to hold the punching device or grinding device by hand and construct around the flange pipe, which can reduce the working strength of the operator, reduce unnecessary work fatigue, increase the convenience of the device, and improve the functionality of the device.

[0005] However, in actual use, the sizes and hole diameters of flange joints often vary. The existing device cannot be compatible when processing flange joints with different sizes and hole diameters, and it is necessary to manually adjust the fixed position and the position of the processing device. In addition, the above-mentioned comparative document only uses an atomizing nozzle to reduce dust, and the atomized water only wets large particle iron filings, and dust with a diameter < 100 μm still suspends in the air; in addition, the wet iron filings deposit on the surfaces of the rotating plate and the fixed base, and need to be manually cleaned regularly. During the cleaning process, secondary dust raising causes the dust concentration in the workshop to rebound, increasing the risk of occupational diseases. Summary of the Invention

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1 Refer to the attached Figures 1 - 4 , a flange pipe joint processing device, including an adjustable mounting sleeve 1 and a debugging member 2 that are rotatable and located on both sides of the workbench respectively, and the adjustable mounting sleeve 1 and the debugging member 2 are on the same horizontal line; The adjustable mounting sleeve 1 includes a plurality of arc-shaped plates 11 slidably mounted on the base 3. The plurality of arc-shaped plates 11 enclose a circular shape. The arc-shaped plate 11 is fixedly installed with a first cutting surface seat 12. A number of flange positioning members are equidistantly distributed on the adjustable mounting sleeve 1; The debugging member 2 includes a plurality of second cutting surface seats 21. The number of the second cutting surface seats 21 is the same as that of the first cutting surface seats 12, and the debugging member 2 can move towards the adjustable mounting sleeve 1; During operation, the structure is placed through the adjustable mounting sleeve 1 to the flange positioning member. Since the length of the adjustable mounting sleeve 1 is sufficient and a number of flange positioning members are provided, multiple flanges can be positioned and processed at one time. By the debugging member 2 entering the adjustable mounting sleeve 1, the second cutting surface seat 21 will squeeze the first cutting surface seat 12, causing the plurality of arc-shaped plates 11 enclosing a circular shape to spread apart, so that the flange can be tightened from the inner hole. In this way, the equipment can process and be compatible with flanges of different sizes and apertures.

[0023] As Figure 1 shown, the workbench includes a left arm 101 and a right arm 102 on both sides, and also includes an electric slide table 103. The left arm 101 and the electric slide table 103 are both fixed on the workbench. The right arm 102 is slidably mounted on the electric slide table 103. A plurality of second cutting surface seats 21 are all fixed on the debugging seat 24. The debugging seat 24 is rotatably mounted on the right arm 102. A motor 7 is fixedly installed on the left arm 101. The output end of the motor 7 is fixed with a turntable 6. A housing 4 is installed on the turntable 6. The base 3 is fixed on the housing 4; By starting the motor 7 to drive the turntable 6 to rotate, the turntable 6 drives the housing 4, and then drives the base 3 to rotate, so that the adjustable mounting sleeve 1 rotates. When the debugging member 2 is inserted into the adjustable mounting sleeve 1 and is tightly inserted, the second cutting surface seat 21 and the first cutting surface seat 12 are in close contact, and the debugging member 2 can be driven to rotate.

[0024] As Figure 2 and Figure 3 shown, a plurality of moving cavities 31 are equidistantly opened on the base 3. A moving seat 32 is slidably mounted in the moving cavity 31. The moving seat 32 is fixed with a bottom plate 33. The arc-shaped plate 11 is fixedly installed on the bottom plate 33. An oil cylinder 41 is fixed in the housing 4. The oil cylinder 41 is communicated with a plurality of oil outlet arms 46. The oil cylinder 41 includes a piston rod 44. The oil outlet arm 46 includes an oil outlet rod 47. The oil outlet rod 47 is fixedly connected with a push rod 43 that can move in the limiting housing 42. The push rod 43 is fixedly connected with the moving seat 32. One end of the debugging member 2 is fixed with a debugging column 45 on the same horizontal line as the piston rod 44. A through hole 48 for the debugging column 45 to pass through is opened on the base 3; After the debugging part 2 enters the adjustable mounting sleeve 1, the debugging column 45 will pass through the through hole 48 to push the piston rod 44, so that the hydraulic oil in the oil cylinder 41 enters the oil outlet arm 46 to squeeze the oil outlet rod 47 to extend. As a result, the oil outlet rod 47 will push the push rod 43 to move, and the movement of the push rod 43 will drive the bottom plate 33 to move. The movement of the bottom plate 33 will drive the arc plate 11 to move. In this way, the movement of the arc plate 11 not only depends on the second cutting surface seat 21 to squeeze the first cutting surface seat 12 to move, but also moves driven by the bottom plate 33, so that multiple arc plates 11 are dispersed, thus improving the stability of the fixed flange.

[0025] As Figure 1 shown, a drilling rig 200 is slidably mounted through the bottom plate 33. An annular frame 5 is mounted outside the housing 4. A plurality of ear plates 300 are fixedly mounted on the annular frame 5. The ear plates 300 are slidably mounted with an electric push rod 400 fixedly connected to the base of the drilling rig 200; The distance from the drilling rig 200 to the arc plate 11 is the distance from the flange hole to the inner hole on the flange. When the flange rotates, the drilling rig 200 rotates simultaneously, and the two are in a relatively static state. When it is necessary to drill holes in the flange, just start the drilling rig 200 and the electric push rod 400. The electric push rod 400 pushes the drilling rig 200 to move towards the flange, so that one drilling rig 200 only drills one place, and the drill bit of the drilling rig 200 is long enough, so that after drilling one flange, it can still drill other flanges at a farther distance, thus improving the operation efficiency.

[0026] In this embodiment, the flange positioning member includes an arc-shaped stop bar 13 fixed on the arc plate 11, and also includes a moving groove 15 formed through the arc plate 11 and the first cutting surface seat 12. An adjustable stop bar 14 is slidably mounted in the moving groove 15. A flange placement area is formed between the arc-shaped stop bar 13 and the adjustable stop bar 14. A stop rod 16 passing through the moving groove 15 is mounted at the bottom of the adjustable stop bar 14. The flange positioning member also includes a transverse groove 22 formed on the second cutting surface seat 21. A number of rubber heads 23 are fixedly arranged at equal intervals in the transverse groove 22; During operation, the flange is placed through the adjustable mounting sleeve 1 into the flange placement area formed between the arc-shaped stop bar 13 and the adjustable stop bar 14. After the debugging part 2 enters the adjustable mounting sleeve 1 and moves into place, the stop rod 16 will be in the transverse groove 22. At this time, the rubber head 23 will squeeze and push the adjustable stop bar 14 to move, so that the adjustable stop bar 14 continuously moves towards the arc-shaped stop bar 13, so that the arc-shaped stop bar 13 and the adjustable stop bar 14 fix the flange from the vertical direction, improving the stability of the fixation.

[0027] Embodiment Two Referring to the attached Figures 5 - 8 , based on Embodiment One, a telescopic cover 8 covering the adjustable mounting sleeve 1 is installed at the debugging part 2. The telescopic cover 8 includes collecting shells 83 having the same number as the flange positioning members; When working, since both the adjustable mounting sleeve 1 and the debugging part 2 can rotate, the flange located on the adjustable mounting sleeve 1 will also rotate accordingly. By using the telescopic cover 8 to completely cover the adjustable mounting sleeve 1, when the rotating flange is being processed, the iron filings generated by it will disperse around due to centrifugal force and will not accumulate on the workbench. And the collection shell 83 will be located around the flange positioning part, so that the iron filings dispersed around will enter the collection shell 83 and be collected and processed.

[0028] Specifically, both sides of the telescopic cover 8 respectively include a left cover head 81 and a right cover head 82. The right cover head 82 is slidably mounted on the right arm 102. Threaded seats 88 are fixed on both sides of the left cover head 81. A driving assembly 9 is provided on the side of the telescopic cover 8. The driving assembly 9 includes a driving housing 91 fixedly mounted on the workbench. A threaded rod 92 is rotatably mounted in the driving housing 91. The threaded seat 88 is threadedly mounted on the threaded rod 92 and is slidably mounted in the driving housing 91. The output end of the motor 7 is fixedly provided with a driving shaft 61. A connecting assembly 93 is provided between the driving shaft 61 and the threaded rod 92. The connecting assembly 93 includes a double-groove pulley fixed on the driving shaft 61, and also includes a driven pulley fixed on the threaded rod 92. A belt is connected between the two. When the motor 7 drives the driving shaft 61 to rotate, it will not only drive the turntable 6 to rotate, but also drive the double-groove pulley to rotate through the driving shaft 61, thereby driving the driven pulley to rotate through the belt, making the threaded rod 92 rotate. In this way, the threaded seat 88 will move on the threaded rod 92 towards the adjustable mounting sleeve 1, so that the telescopic cover 8 can be extended to wrap the adjustable mounting sleeve 1.

[0029] In addition, the right cover head 82 is fixedly connected with an air outlet pipe 86 that penetrates the right arm 102. A filter screen 87 is provided in the air outlet pipe 86. There is a notch near the left cover head 81 inside the telescopic cover 8. Ring seats 85 are fixed on both sides of the notch. A blowing assembly 84 is slidably mounted between the two ring seats 85. The blowing assembly 84 includes a cylinder 841. A plurality of fan blades 842 are fixed inside the cylinder 841. A first magnet 800 is fixed on the side of the cylinder 841 close to the left cover head 81. A second magnet 900 is fixed on the turntable 6. A sliding frame 500 is fixedly mounted on the workbench. A dust collector 600 is slidably mounted on the sliding frame 500. The dust collector 600 is provided with a plurality of telescopic suction pipes 700. The telescopic suction pipes 700 are communicated with the collection shell 83.

[0030] In this embodiment, when the telescopic cover 8 is completely moved into place, start the drilling machine 200 to drill holes in the flange. Drive the flange to rotate by the rotation of the adjustable mounting sleeve 1, so that the iron filings are thrown into the telescopic cover 8 by the centrifugal force generated by the rotating vehicle. And at this time, each flange is located at each collection shell 83, so that the iron filings will enter the collection shell 83. Start the dust collector 600 to suck the iron filings in the collection shell 83 away; In addition, when the telescopic cover 8 is completely moved into place, the turntable 6 enters the telescopic cover 8, and the first magnet 800 on the turntable 6 will magnetically attract the second magnet 900. When the turntable 6 rotates, it can drive the drum 841 to rotate, so that the fan blades 842 generate a blowing wind towards the right arm 102. This wind force can blow the iron filings not located in the collection shell 83 into the collection shell 83, and can also blow the smoke generated during drilling to the right arm 102 and discharge it through the air outlet pipe 86, while the filter screen 87 can filter out the iron filings.

[0031] The present invention also discloses a method for processing a flange pipe joint, which includes the following steps: S1: Pass the flange through the adjustable mounting sleeve 1 and then place it at the flange positioning member; S2: Start the electric slide table 103, so that the right arm 102 drives the debugging member 2 to move towards the adjustable mounting sleeve 1, so that the debugging member 2 enters the adjustable mounting sleeve 1, and the second cutting surface seat 21 will squeeze the first cutting surface seat 12, and the multiple arc-shaped plates 11 will spread out, so that the flange can be tightened from the inner hole; S3: When the debugging member 2 moves, the debugging column 45 will push the piston rod 44, so that the oil outlet rod 47 is extruded to drive the bottom plate 33 of the belt to move. The movement of the bottom plate 33 will drive the drilling machine 200 to move, so that the drilling machine 200 moves to the height where drilling is required on the flange; S4: Start the motor 7 to drive the turntable 6 to rotate. The rotation of the turntable 6 causes the housing 4 to drive the base 3 to rotate. The telescopic cover 8 will move towards the adjustable mounting sleeve 1 until it wraps the adjustable mounting sleeve 1. Then start the drilling machine 200 and the electric push rod 400 to drill the flange, and the generated iron filings enter the collection shell 83 due to centrifugal force and are collected.
