Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange cutting technology, specifically a flange cutting device. Background Technology
[0002] As a core component in pipeline connections, heavy machinery assembly, and pressure vessel sealing, the dimensional accuracy of the annular end face of flanges, such as inner diameter, outer diameter, end face perpendicularity, and cut quality, directly determines the assembly sealing performance and structural stability. Currently, flange cutting and processing mainly uses three types of equipment: flame cutting equipment, plasma cutting equipment, and mechanical milling cutting equipment.
[0003] During laser cutting, flanges are often placed directly on the surface of the cutting bed. The cutting head moves to cut the flange. However, this method can lead to instability and displacement of the flange on the cutting bed during subsequent cutting processes, as there is no limiting structure for the flange. This can cause deviations in the cutting position and damage to the flange, increasing resource consumption and reducing production efficiency.
[0004] Therefore, we propose a flange cutting device to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a flange cutting device that solves the problem mentioned in the background art where, during laser cutting, the flange is often placed directly on the surface of the cutting bed, and the cutting head is used to cut the flange. However, this cutting method leads to the flange shifting on the cutting bed if the cutting device is impacted by external forces during subsequent cutting because the flange is not effectively restrained. This results in deviations in the subsequent cutting position, causing damage to the flange, increasing resource consumption, and reducing production efficiency.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0009] A flange cutting device includes a body, an adjustment frame distributed above one end of the body, an adjustment structure slidably connected to the outer side of the middle section of the adjustment frame, and a lifting seat fixed at the front end of the adjustment structure.
[0010] A laser cutting head is fixedly installed at the bottom center of the lifting seat. A guide groove is opened on the side wall of the lifting seat. A fixed seat is fixedly installed on the side wall of the lifting seat, and a vertical rod passes through the inner side of one end of the fixed seat. A return spring is sleeved on the outer side of the bottom of the vertical rod. A lower pressure seat is fixedly installed at the bottom of the vertical rod, and a ball is rotatably connected to the bottom of the lower pressure seat. A push seat is fixedly installed at the top of the vertical rod, and a guide block is fixedly installed on the side wall of the push seat. A first linkage rod is rotatably connected to one side of the top of the push seat, and a second linkage rod is connected to the other end of the first linkage rod. A damper is rotatably connected to the surface of one end of the first linkage rod.
[0011] Furthermore, a threaded sleeve is fixed on one side of the bottom of the adjustment frame, and the threaded sleeves are symmetrically distributed along the vertical center line of the adjustment frame.
[0012] Furthermore, a drive motor is fixedly installed at one end of the machine body, and a threaded rod is connected to the output end of the drive motor. A cutting bed is fixedly installed in the inner cavity of the machine body.
[0013] Furthermore, the guide grooves are equidistantly distributed along the center point of the lifting seat, and the guide grooves and the lifting seat form an integrated structure.
[0014] Furthermore, the lower pressure seat is slidably connected to the fixed seat via a vertical rod, and the lower pressure seats are equidistantly distributed along the center point of the lifting seat.
[0015] Furthermore, one end of the first linkage rod is rotatably connected to the push seat via a connecting lug, and the other end of the first linkage rod is rotatably connected to the second linkage rod via a connecting lug.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a flange cutting device, which has the following advantages:
[0018] This utility model, through its structure including a vertical rod, a return spring, a pressure seat, and a damper, facilitates effective pressure limiting of the flange during subsequent laser cutting.

[0025] 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.
[0026] Example
[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of the present invention provides a flange cutting device, including a body 1, an adjustment frame 2 distributed above one end of the body 1, an adjustment structure 3 slidably connected to the outer side of the middle section of the adjustment frame 2, and a lifting seat 4 fixed at the front end of the adjustment structure 3.
[0028] A laser cutting head 5 is fixedly mounted at the center of the bottom end of the lifting seat 4. A guide groove 6 is provided on the side wall of the lifting seat 4. A fixed seat 7 is fixedly mounted on the side wall of the lifting seat 4, and a vertical rod 8 passes through the inner side of one end of the fixed seat 7. A hole for the vertical rod 8 to pass through is provided on the inner side of the fixed seat 7. The fixed seats 7 are equidistantly distributed along the center point of the lifting seat 4. A return spring 9 is sleeved on the outer side of the bottom of the vertical rod 8. The two ends of the return spring 9 are respectively connected to one end surface of the lower pressure seat 10 and one side of the bottom of the fixed seat 7. The vertical rod 8 and the lower pressure seat 10 are detachably connected, which facilitates the replacement of the return spring 9 by disassembling the lower pressure seat 10. The lower pressure seat 10 is fixedly mounted at the bottom of the vertical rod 8, and a ball bearing is rotatably connected to the bottom of the lower pressure seat 10. 11. The ball bearing 11 is made of rubber or anti-slip material, and the ball bearing 11 is rotatably connected to the lower pressure seat 10. The top of the vertical rod 8 is fixedly provided with a push seat 12, and the side wall of the push seat 12 is fixedly provided with a guide block 13. The top side of the push seat 12 is rotatably connected to a first linkage rod 14, and the other end of the first linkage rod 14 is connected to a second linkage rod 15. One end of the second linkage rod 15 is rotatably connected to the first linkage rod 14 through a connecting ear, and the other end of the second linkage rod 15 is rotatably connected to the top side of the lifting seat 4 through a connecting ear. One end of the first linkage rod 14 is rotatably connected to a damper 16, and the two ends of the damper 16 are rotatably connected to the first linkage rod 14 and the second linkage rod 15 through connecting ears respectively.
[0029] In use, when the flange needs to be cut, the position of the adjusting frame 2 is adjusted in advance. The adjusting frame 2 drives the adjusting structure 3 to adjust its position. Then, the adjusting structure 3 drives the lifting seat 4 to move longitudinally, which facilitates the subsequent adjustment of the position of the laser cutting head 5, allowing it to better cut the flange. It is worth noting that since the position of the lower pressure seat 10 is slightly lower than that of the laser cutting head 5, the lower pressure seat 10 will make contact with the flange in advance as the laser cutting head 5 moves longitudinally. At this time, the lower pressure seat 10 drives the ball bearing 11 to make contact with the flange. As the lower pressure seat 10 makes contact with the flange, and the lifting seat 4 presses down longitudinally, the lower pressure seat 10 will push the vertical rod 8, causing it to move longitudinally along the fixed seat 7. As the pusher 10 moves, the return spring 9 deforms and generates a reverse force. At the same time, as the vertical rod 8 pushes the pusher 12 longitudinally, the guide block 13 slides along the guide groove 6, thereby improving the stability of the pusher 12 during longitudinal movement. Simultaneously, as the pusher 12 moves longitudinally, the first linkage rod 14, which is rotatably connected to its top end via the connecting ear, pushes the second linkage rod 15, causing the other end of the second linkage rod 15 to rotate along one side wall of the lifting seat 4 via the connecting ear. It is worth noting that as the two linkage rods move, the damper 16 deforms and generates a reverse force. The combination of the reverse force generated by the deformation of the damper 16 and the return spring 9 allows the lower pressure seat 10 to better press and limit the flange, ensuring its stability during subsequent cutting.
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a threaded sleeve 17 is fixedly provided on one side of the bottom of the adjusting frame 2, and the threaded sleeve 17 is symmetrically distributed along the vertical center line of the adjusting frame 2. The inner side of the threaded sleeve 17 is provided with a threaded hole with an inner diameter size matching the outer diameter size of the threaded rod 19. One end of the machine body 1 is fixedly provided with a drive motor 18, and the output end of the drive motor 18 is connected to the threaded rod 19. The drive motor 18 is electrically connected to an external power source through a wire, and the operation of the drive motor 18 is controlled by the electrical signal emitted by the controller. The drive motor 18 is a SA67-YVP0.25-4P type motor with a self-locking structure and capable of forward and reverse rotation. The outer surface of the threaded rod 19 is provided with an external thread, and the threaded rod 19 is symmetrically distributed along the vertical center line of the machine body 1. The screw directions of the external threads on the outer surfaces of the threaded rods 19 on both sides are arranged in opposite directions. The inner cavity of the machine body 1 is fixedly provided with a cutting bed 20. The surface of the cutting bed 20 is arrayed with multiple conical protrusions, and there is a certain gap between the multiple conical protrusions.
[0031] In use, the operation of the drive motor 18 will cause the threaded rod 19 connected to its output end to rotate. At this time, the rotation of the threaded rod 19 will drive the threaded sleeve 17 connected to its outer surface to move. Then, the lateral movement of the threaded sleeve 17 will realize the position adjustment of the adjustment frame 2, which will facilitate the subsequent adjustment of the position of the laser cutting head 5 according to the actual use requirements. Before use, the flange to be processed needs to be placed on the surface of the cutting bed 20 for subsequent processing.
[0032] like Figure 4 As shown, in some embodiments, the guide grooves 6 are equidistantly distributed along the center point of the lifting seat 4, and the guide grooves 6 and the lifting seat 4 form an integrated structure.
[0033] When in use, the opening of the guide groove 6 facilitates the subsequent movement of the guide block 13 along its inner side when the push base 12 moves longitudinally, thereby improving the stability of the push base 12 during longitudinal movement.
[0034] like Figure 5 As shown, in some embodiments, the lower pressure seat 10 is slidably connected to the fixed seat 7 via the vertical rod 8, and the lower pressure seat 10 is equidistantly distributed along the center point of the lifting seat 4.
[0035] During use, as the pressure seat 10 moves longitudinally, the vertical rods 8 fixed on both sides of its top end will slide along the fixed seat 7, thereby improving the stability of the pressure seat 10 during longitudinal movement.
[0036] like Figure 5 As shown, in some embodiments, one end of the first linkage rod 14 is rotatably connected to the push seat 12 via a connecting ear, and the other end of the first linkage rod 14 is rotatably connected to the second linkage rod 15 via a connecting ear.
[0037] In use, as the push base 12 is pushed, one end of the first linkage rod 14 will rotate along one side of the top of the push base 12, while the other end will push the second linkage rod 15, thereby realizing the movement of the second linkage rod 15.
[0038] In summary, the flange to be processed is placed on the cutting bed 20 beforehand. Then, the drive motor 18 operates, causing the threaded rod 19 to drive the adjusting frame 2 for position adjustment. The adjusting frame 2 then drives the adjusting structure 3 for position adjustment. The adjusting structure 3 then drives the lifting seat 4 to move longitudinally, thus adjusting the position of the laser cutting head 5 to better cut the flange. Since the lower pressure seat 10 is slightly lower than the laser cutting head 5, it will contact the flange beforehand as the laser cutting head 5 moves longitudinally. At this time, the lower pressure seat 10 drives the ball bearings 11 to contact the flange. As the lower pressure seat 10 contacts the flange and the lifting seat 4 presses down longitudinally, the lower pressure seat 10 pushes the vertical rod 8, causing it to move longitudinally along the fixed seat 7. Furthermore, as the lower pressure seat 10... As the pusher moves, the return spring 9 deforms and generates a reverse force. Simultaneously, as the vertical rod 8 pushes the pusher 12 longitudinally, the guide block 13 slides along the guide groove 6, thereby improving the stability of the pusher 12 during longitudinal movement. At the same time, as the pusher 12 moves longitudinally, the first linkage rod 14, which is rotatably connected to its top end via the connecting ear, pushes the second linkage rod 15, causing the other end of the second linkage rod 15 to rotate along one side wall of the lifting seat 4 via the connecting ear. It is worth noting that as the two linkage rods move, the damper 16 deforms and generates a reverse force. The combination of the reverse force generated by the deformation of the damper 16 and the return spring 9 allows the lower pressure seat 10 to better press and limit the flange, ensuring its stability during subsequent cutting.
[0039] 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.
