Description

Technical Field

[0001] The invention relates to the field of cutting of pipe gallery supports and hangers, and in particular to a cutting device and method for producing pipe gallery supports and hangers. Background Art

[0002] Pipeline support hangers are an important part of the pipeline system, used to support and fix pipelines to ensure the stability and safety of pipelines. Pipeline support hangers are usually mainly composed of multiple hollow pipes. During the production and processing of pipe gallery support hangers, some hollow pipes often need to be cut into a small section to reach a specific length to meet the structural design requirements.

[0003] However, since most of the hollow pipes of the pipe gallery supports and hangers have thin walls, the cutter of the existing cutting device can usually only fix and limit the outer sides of the hollow pipe when cutting the hollow pipe, and cannot support the inner wall of the hollow pipe from the inside of the hollow pipe, so that the upper part of the hollow pipe is easily deformed due to the pressure of the cutter. Although the hollow pipe can be cut, the quality of the subsequent pipe gallery supports and hangers is affected. At the same time, metal debris will be generated in the process of the cutter cutting the pipe body. The metal debris will adhere to the blade of the cutter or both sides of the cutter, causing the cutter to become less sharp, thereby affecting the cutting effect. To this end, we propose a cutting device and method for the production of pipe gallery supports and hangers. Summary of the invention

[0037] The supporting mechanism includes a fixed plate 3 24, which is fixedly connected to the upper end of the base 1, and the fixed plate 3 24 is fixedly connected to the wall surface of the fixed plate 1 2 corresponding to the fixed plate 1, and the extended shaft end of the electric push rod 25 is fixedly connected to the sliding block 26, and the upper and lower ends of the sliding block 26 are respectively fitted with the internal top and bottom ends of the tube body 16, and the side wall of the sliding block 26 away from the electric push rod 25 is fixedly connected to the fixed block 27, and the top of the fixed block 27 is fixedly installed with a distance sensor 28, and the front and rear ends of the sliding block 26 are fixedly connected to the fixed block 3 31, and the upper parts of the two fixed blocks 31 are elastically connected to the concave frame through elastic components. 34, a second motor 35 is fixedly installed on the inner side of the two concave frames 34, and the output shaft ends of the two second motors 35 are fixedly connected with a rotating column 2 36. The two rotating columns 2 36 are respectively movable and penetrate the two concave frames 34, and the corresponding ends of the two rotating columns 2 36 are commonly fixedly connected with a U-shaped plate 37, and one side wall of the U-shaped plate 37 is in contact with a side wall of the fixed block 27, and the top of the U-shaped plate 37 is in contact with the inner top of the tube body 16. The gap width between the U-shaped plate 37 and the sliding block 26 is equal to the gap width between the fixed concave plate 1 17 and the fixed concave plate 2 18, and a pushing mechanism is provided between the U-shaped plate 37 and the sliding block 26.

[0038] The elastic component includes a sliding column 32, which slides and penetrates the inner wall of the fixed block 31, and the top of the sliding column 32 is fixedly connected to the lower end of the concave frame 34. A spring 33 is slidingly sleeved on the outer wall of the sliding column 32, and the spring 33 is fixedly connected between the concave frame 34 and the fixed block 31.

[0039] The pushing mechanism includes an electric push rod 3 29, which is fixedly connected to the bottom of the sliding block 26. The telescopic shaft end of the electric push rod 3 29 is fixedly connected to a push plate 30. The upper edge of the push plate 30 away from the electric push rod 3 29 is in contact with the bottom of the U-shaped plate 37, and the lower end of the push plate 30 is in contact with the inner bottom end of the tube body 16.

[0040] In this embodiment, the tube body 16 to be cut is placed inside the fixed concave plate 17 and the fixed concave plate 2 18, and then the two electric push rods 14 are started, and the two electric push rods 14 can drive the clamping blocks 15 connected to them to move toward the tube body 16 until the two clamping blocks 15 contact the tube body 16, thereby fixing the tube body 16. Then the first motor 3 is started, and the first motor 3 can drive the disc 4 to rotate, and the disc 4 drives the eccentrically arranged cylinder 7 thereon to perform circular motion with the center of the disc 4 as the axis, and the cylinder 7 drives the rotating rod 6 to reciprocate up and down by sliding inside the notch 38 with the connection between the rotating column 1 5 and the rotating rod 6 as the axis.

[0041] When the rotating rod 6 drives the cutter 8 to rotate downward, the rotating rod 6 drives the cutter 8 to approach the tube body 16 and contact the upper surface of the tube body 16. At this time, the cutter 8 will contact the top of one of the sliding blocks 23. As the cutter 8 continues to rotate downward, the cutter 8 pushes the sliding block 23 to move downward and compresses the corresponding spring 21. The sliding block 23 will drive the corresponding sliding column 22 to slide downward in the corresponding cylindrical groove 20, and the continued downward rotation of the cutter 8 will always push the sliding block 23 downward, so that the sliding block 23 will finally enter the corresponding rectangular groove 19. As the cutter 8 continues to rotate downward, it will push another sliding block 23 downward. The other sliding block 23 will also squeeze the corresponding spring 21 and drive the corresponding sliding column 22 to slide downward in the corresponding cylindrical groove 20, and the other sliding block 23 will also enter the corresponding rectangular groove 19. It should be noted that, under the action of the two sliding blocks 23, the two sides of the cut portion of the tube body 16 can be supported, thereby improving the stability of the position of the cut portion of the tube body 16 when the tube body 16 is cut.

[0042] At the same time, when the cutter 8 cuts along the upper surface of the tube body 16, the sliding block 26 and the U-shaped plate 37 are respectively supported on the top of the tube body 16, so that when the cutter 8 cuts into the upper part of the tube body 16, the thin-walled tube body 16 is prevented from being deformed. When the cutter 8 continues to rotate downward to cut into the middle part of the tube body 16, the cutter 8 will approach the distance sensor 28, and the distance sensor 28 can identify the cutter 8 (the distance sensor 28 is electrically connected to the electric push rod 3 29), thereby starting the electric push rod 3 29, and the electric The push rod 3 29 will drive the push plate 30 to start moving in the direction close to the sliding block 26, and the end of the push plate 30 will leave the bottom of the U-shaped plate 37. At this time, the two springs 2 33 that were originally in an extended state will drive the corresponding concave frames 34 to move vertically downward through the elastic contraction force. The two concave frames 34 drive the two sliding columns 2 32 to slide downward in the two fixed blocks 3 31 respectively, and the two concave frames 34 can drive the U-shaped plate 37 to move downward, and the top end of the U-shaped plate 37 can leave the inner top end of the tube body 16. At the same time, the two concave frames 34 can drive the second motors 35 connected to them to move downward synchronously. At the same time, the two second motors 35 are started, and the two second motors 35 can drive the rotating columns 2 36 connected to them to rotate synchronously clockwise, and the two rotating columns 2 36 drive the U-shaped plate 37 to rotate clockwise, so that the U-shaped plate 37 rotates smoothly until the U-shaped plate 37 rotates ninety degrees clockwise. At this time, the electric push rod 2 25 is started, and the electric push rod 2 25 can drive the sliding block 2 26, the electric push rod 3 29, the push plate 30, the two fixed blocks 31 and the U-shaped plate 37 to move outward inside the tube body 16 and finally move out of the tube body 16 to avoid affecting the subsequent rotation trajectory of the cutter 8.

[0043] Finally, the downward rotation of the cutter 8 can completely cut off the tube 16, and then the cutter 8 will rotate upward to reset due to the continued rotation of the disc 4 and the cylinder 7, and then the first motor 3 will be powered off, so that the cutter 8 will no longer reciprocate, and then the staff can take away the small section of the tube 16 cut out. Under the action of the spring 1 21, the two sliding blocks 1 23 will also move up and reset, so as to support the cut-off parts on both sides of the next tube 16. Then, the electric push rod 3 29 is started, so that the electric push rod 3 29 drives the push plate 30 to move toward the U-shaped plate 37, so that the end of the push plate 30 squeezes the U-shaped plate 37, and the U-shaped plate 37 will continue to move up and stretch the spring 2 33, and the upper end of the U-shaped plate 37 will be flush with the upper end of the sliding block 2 26.

[0044] Example 2: Please refer to Figure 1-Figure 3The present embodiment further explains the first embodiment, the scraping mechanism includes a fixing plate 2 9, the fixing plate 2 9 is fixedly connected to the side wall of the fixing plate 2 near the upper edge, the lower surface of the fixing plate 2 9 is symmetrically fixedly connected with fixing columns 10, the bottom ends of the two fixing columns 10 are fixedly connected with connecting plates 11, the upper surfaces of the two connecting plates 11 are fixedly connected with arc-shaped rubber scrapers 12, and the two arc-shaped rubber scrapers 12 are respectively in contact with the two side walls of the cutter 8.

[0045] In this embodiment, when the cutter 8 starts to rotate downward toward the tube body 16, the cutter 8 will open the two arc-shaped rubber scrapers 12, and the two arc-shaped rubber scrapers 12 always contact the two sides of the cutter 8, and at the same time, the cutter 8 and the rotating rod 6 can smoothly pass through the gap between the two connecting plates 11.

[0046] When the cutter 8 completely cuts off the tube 16, the first motor 3 continues to drive the disc 4 and the cylinder 7 to rotate, which can drive the rotating rod 6 and the cutter 8 to rotate upward and away from the tube 16. At this time, the rotating rod 6 will first pass through the gap between the two connecting plates 11 and between the two curved rubber scrapers 12. When the cutter 8 passes between the two curved rubber scrapers 12, the two curved rubber scrapers 12 always contact the two sides of the cutter 8 and scrape off the debris that has just cut off the tube 16 and attached to the two sides of the cutter 8, so as to avoid the long-term attachment of debris on the two sides of the cutter 8 to affect the normal use of the cutter 8. The curved rubber scraper 12 is an elastic body, which will deform when subjected to external force and recover when the external force is lost.

[0047] See also Figure 1-Figure 10 The present invention also discloses a cutting method for producing pipe gallery support and hanger brackets, comprising the following steps:

[0048] S1: First, place the tube body 16 inside the fixed concave plate 1 17 and the fixed concave plate 2 18, and fix the tube body 16 by a clamping mechanism;

[0049] S2: Subsequently, the cutter 8 is driven by the transmission mechanism to cut the tube body 16, and during the cutting process, a supporting mechanism and an auxiliary support mechanism are provided to assist the cutter 8 in cutting the tube body 16 stably and without deformation;

[0050] S3: Subsequently, the distance sensor 28 recognizes that the cutter 8 has cut off the upper part of the tube body 16, and the electric push rod 25 is started and the supporting mechanism is pulled out from the inside of the tube body 16 to avoid obstructing the movement path of the cutter 8;

[0051] S4: Finally, the scraping mechanism can be used to scrape away the metal debris attached to the surface of the cutter 8 to avoid affecting the subsequent cutting effect.
