[0002] In the production process of flanges, hole drilling is one of the key process links, which mainly includes large-diameter holes in the center of the flange and circumferentially distributed screw assembly holes. At present, laser cutting devices are generally used in the industry to perform hole drilling of flanges. However, existing devices usually use a single laser head or a single-station processing method. When drilling the center hole of the flange and the circumferential mounting holes, they need to be processed one by one, and synchronous processing cannot be achieved.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] In order to shorten the processing time and improve the production efficiency of the flange, as an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3As shown, a cutting device and method for flange production described in the present invention include a flange bearing support assembly for placing flanges, a flange fastening and clamping assembly is provided below the flange bearing support assembly, the flange bearing support assembly is connected to a support column 1, the upper end of the support column 1 is fixedly connected to a truss 2, a main laser cutting operation assembly is provided above the flange bearing support assembly, a transmission assembly is provided on the outside of the main laser cutting operation assembly, an auxiliary laser cutting operation assembly is provided on the outside of the transmission assembly, a driving assembly for driving the main laser cutting operation assembly to move and rotate is provided above the main laser cutting operation assembly, and the transmission assembly is used to drive the auxiliary laser cutting operation assembly to work.

[0020] When in use, first, place the flange to be processed steadily on the flange bearing support assembly, then start the flange fastening and clamping assembly to clamp the flange to ensure that the flange is stable and does not move during the subsequent processing; then, start the driving assembly to adjust the height of the main laser cutting operation assembly and the auxiliary laser cutting operation assembly to accurately align them with the predetermined cutting part of the flange; Subsequently, the main laser cutting component is driven by the driving component to start rotating. During the rotation of the main laser cutting component, the central aperture of the flange is cut. At the same time, the auxiliary laser cutting component is driven by the transmission component to operate synchronously. The auxiliary laser cutting component cuts the bolt assembly hole on the flange, thereby realizing simultaneous processing of multiple parts, greatly shortening the overall processing time and significantly improving the production efficiency of the flange. When a group of auxiliary laser cutting components successfully completes the cutting task of a group of bolt assembly holes, the transmission component drives the auxiliary laser cutting component to rotate precisely around its own axis until the auxiliary laser cutting component moves smoothly to the next preset cutting position. At this time, the transmission component drives the auxiliary laser cutting component to work again, and then starts the cutting operation of the next group of bolt assembly holes. The above operation can be repeated to achieve synchronous cutting of several groups of bolt assembly holes evenly distributed on the outer circumference of the flange while cutting the center aperture of the flange. There is no need to reposition the auxiliary laser cutting component and adjust the cutting parameters after each bolt assembly hole is processed, which further improves the processing efficiency and provides a guarantee for the efficient and high-quality production of flanges.

[0021] In order to facilitate the cutting operation of the center hole of the flange, for example, Figure 4 , Figure 8 , Fig. 9As shown, the present invention also includes that the main laser cutting operation component includes a horizontally arranged rotating disk 3, a radially arranged slide groove 4 is provided on the rotating disk 3, an electric slider 5 is slidably connected in the slide groove 4, and the lower surface of the electric slider 5 is detachably connected to the first laser gun body 6; the upper surface of the rotating disk 3 is detachably connected to an outer gear ring 7 that meshes with the transmission component for transmission.

[0022] When in use, the first laser gun body 6 is installed on the lower surface of the electric slider 5 in a detachable connection manner to ensure that the connection is firm, and then the outer gear ring 7 is installed on the upper surface of the rotating disk 3 in a detachable connection manner. According to the cutting requirements of the central aperture of the flange, the electric slider 5 is started, and the electric slider 5 slides radially in the slide groove 4 on the rotating disk 3 to adjust the radial position of the first laser gun body 6 on the rotating disk 3 so that the first laser gun body 6 is aligned with the starting cutting position of the central aperture of the flange; The driving assembly drives the rotating disk 3 to rotate. When the rotating disk 3 rotates, the outer gear ring 7 engages with the transmission assembly for transmission. During the rotation of the rotating disk 3, the first laser gun body 6 moves in a circular motion with the rotating disk 3 to cut the central aperture of the flange.

[0023] In order to facilitate the cutting operation of the bolt assembly holes on the flange, for example, Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig.11 As shown, the present invention also includes that the auxiliary laser cutting operation assembly includes an outer transmission ring 8 rotatably connected to the outer side of the transmission assembly, the outer transmission ring 8 is provided with at least two groups of rotationally symmetrical arc-shaped waist grooves 9, and the upper surface of the arc-shaped waist groove 9 is provided with a connecting seat 10, and the connecting seat 10 is threadedly connected with the bolt hole provided on the outer transmission ring 8 through the mounting bolt 11; A vertically arranged rotating shaft 12 is rotatably connected in the connecting seat 10, a first mounting plate 13 is fixedly connected to the lower end of the rotating shaft 12, a plurality of mounting holes 14 are provided on the first mounting plate 13, a second vertically arranged laser gun body 15 is provided on the lower surface of the first mounting plate 13, a second mounting plate 16 is fixedly connected to the upper end of the second laser gun body 15, and the second mounting plate 16 is threadedly connected to the corresponding mounting holes 14 through assembling bolts 17; the upper end of the rotating shaft 12 is fixedly connected to a first gear 18 meshing with a transmission assembly, and a friction ring 19 is connected to the upper surface of the outer transmission ring 8 through a connecting rod and frictionally transmitted with the transmission assembly.

[0024] When in use, according to the distribution of the bolt assembly holes on the flange and the cutting requirements, loosen the mounting bolts 11 on the connecting seat 10, move the connecting seat 10 to a suitable position along the arc-shaped waist groove 9, adjust the position of the second laser gun body 15, align it with the starting position of the bolt assembly hole to be processed, and then tighten the mounting bolts 11; When faced with different bolt assembly hole diameter requirements on flanges of different specifications, the operator can select a suitable mounting hole 14 for connection. For example, for the cutting of a bolt assembly hole with a smaller diameter, the second mounting plate 16 can be connected to the mounting hole 14 near the center of the rotating shaft 12. At this time, the laser beam is focused on a smaller area, and the cut aperture diameter is correspondingly smaller; for a bolt assembly hole with a larger diameter, the mounting hole 14 away from the center of the rotating shaft 12 is selected to connect the second mounting plate 16, so that the second laser gun body 15 is offset outward, thereby increasing the range of action of the laser beam, thereby cutting a larger aperture that meets the requirements, and realizing the requirements for different apertures; When the main laser cutting component starts to work and drives the transmission component to operate, the transmission component drives the rotating shaft 12 to rotate through the meshing transmission with the first gear 18, so that the second laser gun body 15 makes a circular motion around the flange. At the same time, the second laser gun body 15 emits a laser beam to cut the bolt assembly holes on the flange. When the transmission component drives the rotating shaft 12 to rotate, the transmission component cannot drive the outer transmission ring 8 to rotate. When the cutting task of this group of bolt assembly holes is completed, the transmission component drives the outer transmission ring 8 to rotate around its own axis until the outer transmission ring 8 rotates and moves smoothly to the next preset cutting position. At this time, the transmission component exerts force again and drives the group of rotating shafts 12 to rotate again, so as to carry out the cutting operation of the next group of bolt assembly holes.

[0025] In order to improve the overall processing efficiency, for example, Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig.10 As shown, the present invention also includes that the transmission assembly includes an inner transmission ring 20 rotatably connected to the outer side of the rotating disk 3, the outer side of the inner transmission ring 20 is rotatably connected to the inner side of the outer transmission ring 8, the upper end of the inner transmission ring 20 is rotatably connected to a plurality of groups of circumferentially distributed and vertically arranged transmission shafts 21, the lower end of the transmission shaft 21 is fixedly connected to the outer gear ring 7 to mesh with the second gear 22 for transmission, the middle part of the transmission shaft 21 is fixedly connected to the friction transmission wheel 23 for friction transmission with the friction ring 19, the upper end of the transmission shaft 21 is fixedly connected to the transmission half-tooth 24 for intermittent transmission with the first gear 18, the radius of the transmission half-tooth 24 is larger than the radius of the first gear 18; the upper surface of the inner transmission ring 20 is fixedly connected to the driving assembly through a support rod 25.

[0026] When in use, when the driving assembly is started and drives the rotating disk 3 to rotate, the outer gear ring 7 on the rotating disk 3 meshes with the second gear 22 at the lower end of the transmission shaft 21, thereby driving the transmission shaft 21 to rotate. As the transmission shaft 21 rotates, the friction transmission wheel 23 and the transmission half-tooth 24 operate synchronously. The friction transmission wheel 23 drives the outer transmission ring 8 to rotate through the friction ring 19, thereby driving the rotating shaft 12 to revolve around the flange. After the first gear 18 at the upper end of the rotating shaft 12 revolves around the flange for a certain angle, it is blocked by the transmission half-tooth 24 and meshes with the transmission half-tooth 24, thereby driving the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, the first mounting plate 13, the second mounting plate 16 and the second laser gun body 15 at the lower end of the rotating shaft 12 rotate together. At this time, the second laser gun body 15 emits a high-energy laser beam to cut the bolt assembly holes on the flange. During the meshing transmission between the transmission half-tooth 24 and the first gear 18, the first gear 18 cannot pass over the transmission half-tooth 24, resulting in the first gear 18 and the transmission shaft 21 being unable to revolve around the flange, and the transmission shaft 21 can only rotate on its own. At this time, the friction transmission wheel 23 cannot drive the friction ring 19 to rotate, so that relative sliding occurs between the friction transmission wheel 23 and the friction ring 19 on the outer transmission ring 8; and the friction transmission of the friction transmission wheel 23 and the friction ring 19 can provide support for the outer transmission ring 8, so that the first gear 18 and the transmission half-tooth 24 are squeezed, thereby ensuring the stability of the transmission of the first gear 18 and the transmission half-tooth 24; After the first gear 18 and the group of transmission half teeth 24 are continuously meshed and transmitted to a specific position, the two are disengaged. At this time, the transmission half teeth 24 cannot block the first gear 18, and the friction transmission between the friction transmission wheel 23 and the friction ring 19 drives the outer transmission ring 8 to rotate smoothly until the outer transmission ring 8 moves to the position of the next transmission half teeth 24. The first gear 18 at the upper end of the rotating shaft 12 is blocked by another group of transmission half teeth 24 and re-engages with the group of transmission half teeth 24. With the help of the transmission half teeth 24, the rotating shaft 12 rotates again, thereby prompting the second laser gun body 15 to restart the work and cut the next group of bolt assembly holes. By cycling the above operations, while the main laser cutting operation component cuts the central aperture of the flange, the auxiliary laser cutting operation component can achieve synchronous cutting of several groups of bolt assembly holes evenly distributed on the outer circumference of the flange, thereby improving the overall processing efficiency and effectively shortening the production cycle. The support rod 25 can ensure the overall stability of the inner transmission ring 20 and make the transmission shaft 21 rotate more smoothly.

[0027] In order to facilitate the rotation of the rotating disk 3, for example, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the present invention also includes that the driving assembly includes a horizontally arranged moving plate 26, the lower surface of the moving plate 26 is connected to the fixed end of the driving motor 27, the output end of the driving motor 27 is fixedly connected to the upper surface of the rotating disk 3, and the upper end of the supporting rod 25 is fixedly connected to the lower surface of the moving plate 26; A horizontally arranged fixed plate 28 is provided above the movable plate 26, and a vertically arranged electric hydraulic cylinder 29 is fixedly connected to the upper surface of the fixed plate 28. The output end of the electric hydraulic cylinder 29 passes through the fixed plate 28 and is fixedly connected to the upper surface of the movable plate 26, and the fixed end of the electric hydraulic cylinder 29 is fixedly connected to the lower surface of the truss 2.

[0028] When in use, when it is necessary to perform hole drilling on the flange, the electric hydraulic cylinder 29 is started, and the output end of the electric hydraulic cylinder 29 drives the movable plate 26 to move up and down in the vertical direction. By controlling the extension and contraction amount of the electric hydraulic cylinder 29, the height of the movable plate 26 can be adjusted, and then the height of the rotating disk 3 and the main laser cutting operation component can be adjusted to align with the predetermined cutting position of the flange; When the first laser gun head body and the second laser gun head are moved to the appropriate positions, the drive motor 27 is started, and the drive motor 27 drives the rotating disk 3 to rotate, so that the main laser cutting operation component starts to work. When the rotating disk 3 rotates, the auxiliary laser cutting operation component is driven by the transmission component to start working, and thereby the flange is opened.

[0029] In order to ensure the movement stability of the moving plate 26, for example, Figure 3 , Figure 4 As shown, the present invention also includes that the movable plate 26 is provided with a plurality of groups of vertically arranged positioning rods 30 , the fixed plate 28 is provided with positioning holes 31 corresponding to the positioning rods 30 , and the positioning rods 30 are located in the positioning holes 31 and are slidably connected to the positioning holes 31 .

[0030] During use, when the electric hydraulic cylinder 29 starts to drive the moving plate 26 to move in the vertical direction, the positioning rod 30 slides synchronously in the positioning hole 31. During the movement, the cooperation between the positioning rod 30 and the positioning hole 31 plays a guiding role, ensuring that the moving plate 26 moves up and down smoothly, avoiding the moving plate 26 from deflecting or shaking, and ensuring that the drive motor 27, rotating disk 3 and main laser cutting operation assembly installed on the moving plate 26 can accurately align with the predetermined cutting position of the flange.

[0031] For example, Figure 1 , Figure 2 , Figure 3As shown, the present invention also includes that the flange bearing support assembly includes a horizontally arranged flange cutting bearing platform 32, a central positioning opening 33 is provided in the middle of the flange cutting bearing platform 32, a plurality of groups of edge auxiliary openings 34 are distributed on the outer circumference of the flange cutting bearing platform 32, a plurality of groups of vertically arranged fixing rods 35 are fixedly connected to the lower surface of the flange cutting bearing platform 32, a lower end of the fixing rod 35 is fixedly connected to a supporting cross plate 36, and both ends of the supporting cross plate 36 are fixedly connected to the support column 1.

[0032] When in use, the two ends of the supporting horizontal plate 36 are accurately connected to the supporting column 1, and the flange cutting bearing platform 32 is firmly fixed on the supporting horizontal plate 36 through the fixing rod 35, so that the flange cutting bearing platform 32 is kept in a horizontal state; Place the flange to be processed on the flange cutting support platform 32, use the central positioning opening 33 in the middle of the flange cutting support platform 32 to align the center of the flange with the central positioning opening 33, and preliminarily determine the central position of the flange in the horizontal direction; the waste material under the center cutting of the flange can fall through the central positioning opening 33; the waste material in the bolt assembly hole of the flange can fall through the edge auxiliary opening 34, so as to facilitate the separation of the cut waste material from the flange.

[0033] In order to ensure the stability of the flange during the cutting process, for example, Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes that the flange fastening and clamping assembly includes a plurality of groups of slots 37 penetratingly arranged on the flange cutting bearing platform 32, the slots 37 are distributed circumferentially, and mechanical clamps 38 are provided in the slots 37, and the mechanical clamps 38 are rotatably connected to the inner wall of the slots 37 through a spring shaft 39; the lower end of the mechanical clamp 38 is fixedly connected to a horizontally arranged driving plate 40, and one side of the supporting cross plate 36 is fixedly connected to an electric hydraulic telescopic rod 41, and the output end of the electric hydraulic telescopic rod 41 is fixedly connected to the lower surface of the driving plate 40.

[0034] When in use, the flange to be processed is accurately placed on the flange cutting bearing platform 32 to complete the positioning operation, and the electric hydraulic telescopic rod 41 is started to drive the driving plate 40 to move downward. When the driving plate 40 moves downward, it drives the mechanical clamping claw 38 to rotate around the spring shaft 39. Multiple mechanical clamping claws 38 act synchronously and gradually tighten from different directions to firmly clamp the edge of the flange, so that the flange remains stable during the subsequent cutting process to avoid displacement or shaking, thereby ensuring the accuracy and quality of the cutting process; After the flange cutting process is completed, the output end of the electric hydraulic telescopic rod 41 is controlled to retract upward, and the drive plate 40 moves upward as the output end retracts. The mechanical clamp 38 rotates around the inner wall of the groove 37 under the action of the spring shaft 39, gradually loosening the clamping of the flange, making it convenient to take out the processed flange.

[0035] For example, Figure 1 , Figure 3 As shown, the present invention also includes that the lower surface of the flange cutting bearing platform 32 is provided with a horizontally arranged collecting plate 42, and the lower surface of the collecting plate 42 is detachably connected to the upper surface of the driving plate 40 through a driving rod 43.

[0036] During use, when the flange fastening and clamping assembly is working, the electric hydraulic telescopic rod 41 drives the driving plate 40 to move downward to clamp the flange, and the driving plate 40 will drive the collecting plate 42 to move downward synchronously. During the laser cutting process of the flange, the debris and waste slag generated will fall down, and the collecting plate 42 can receive these debris and waste slag to prevent them from scattering everywhere, making it easy to collect and clean them.

[0037] The present invention also provides a cutting method for flange production, which uses the above-mentioned cutting device for flange production and includes the following steps: Step 1: Place the flange to be cut on the flange bearing support assembly; Step 2: Clamp and fix the flange to be cut by the flange fastening clamping assembly; Step 3: Adjust the positions of the main laser cutting component and the auxiliary laser cutting component according to the flange processing requirements; Step 4: While driving the main laser cutting component to cut the flange, the auxiliary laser cutting component is automatically driven to work.

[0038] When the present invention is used, the flange to be processed is placed on the flange cutting bearing platform 32, so that the center of the flange is aligned with the center positioning opening 33, and the initial positioning is completed; The electric hydraulic telescopic rod 41 is started, and its output end drives the driving plate 40 to move downward, and the driving plate 40 drives the mechanical clamping claws 38 to rotate around the spring shaft 39. The multiple mechanical clamping claws 38 are tightened synchronously from different directions to firmly clamp the edge of the flange to ensure the stability of the flange during the processing. At the same time, the driving plate 40 will drive the collecting plate 42 to move downward synchronously to receive the debris and waste residue generated during the processing; According to the cutting requirements of the center aperture of the flange, the electric slider 5 is started, and the electric slider 5 radially slides in the slide groove 4 on the rotating disk 3, so as to adjust the radial position of the first laser gun body 6 on the rotating disk 3, so that the first laser gun body 6 is aligned with the starting cutting position of the center aperture of the flange; Start the electric hydraulic cylinder 29, and its output end drives the moving plate 26 to move in the vertical direction. The positioning rod 30 on the moving plate 26 slides synchronously in the positioning hole 31 of the fixed plate 28 to ensure the smooth movement of the moving plate 26, and then adjust the height of the rotating disk 3 and the main and auxiliary laser cutting components to accurately align them with the predetermined cutting part of the flange; The driving motor 27 is started, and the driving motor 27 drives the rotating disk 3 to rotate. When the rotating disk 3 rotates, the rotating disk 3 drives the first laser gun body 6 to cut the central aperture of the flange; When the driving motor 27 drives the rotating disk 3 to rotate, the outer gear ring 7 on the rotating disk 3 meshes with the second gear 22 at the lower end of the transmission shaft 21, thereby driving the transmission shaft 21 to rotate. As the transmission shaft 21 rotates, the friction transmission wheel 23 and the transmission half-tooth 24 operate synchronously. The friction transmission wheel 23 drives the outer transmission ring 8 to rotate through the friction ring 19, thereby driving the rotating shaft 12 to revolve around the flange. After the first gear 18 at the upper end of the rotating shaft 12 revolves around the flange for a certain angle, it is blocked by the transmission half-tooth 24 and meshes with the transmission half-tooth 24, thereby driving the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, the first mounting plate 13, the second mounting plate 16 and the second laser gun body 15 at the lower end of the rotating shaft 12 rotate together. At this time, the second laser gun body 15 emits a high-energy laser beam to cut the bolt assembly holes on the flange. During the meshing transmission between the transmission half-tooth 24 and the first gear 18, the first gear 18 cannot pass over the transmission half-tooth 24, resulting in the first gear 18 and the transmission shaft 21 being unable to revolve around the flange, and the transmission shaft 21 can only rotate on its own. At this time, the friction transmission wheel 23 cannot drive the friction ring 19 to rotate, so that relative sliding occurs between the friction transmission wheel 23 and the friction ring 19 on the outer transmission ring 8; and the friction transmission of the friction transmission wheel 23 and the friction ring 19 can provide support for the outer transmission ring 8, so that the first gear 18 and the transmission half-tooth 24 are squeezed, thereby ensuring the stability of the transmission of the first gear 18 and the transmission half-tooth 24; After the first gear 18 and the group of transmission half teeth 24 are continuously meshed and transmitted to a specific position, the two are disengaged. At this time, the transmission half teeth 24 cannot block the first gear 18, and the friction transmission between the friction transmission wheel 23 and the friction ring 19 drives the outer transmission ring 8 to rotate smoothly until the outer transmission ring 8 moves to the position of the next transmission half teeth 24. The first gear 18 at the upper end of the rotating shaft 12 is blocked by another group of transmission half teeth 24 and re-engages with the group of transmission half teeth 24. With the help of the transmission half teeth 24, the rotating shaft 12 rotates again, thereby prompting the second laser gun body 15 to restart the work and cut the next group of bolt assembly holes. By cycling the above operations, while the main laser cutting operation component cuts the central aperture of the flange, the auxiliary laser cutting operation component can achieve synchronous cutting of several groups of bolt assembly holes evenly distributed on the outer circumference of the flange, thereby improving the overall processing efficiency and effectively shortening the production cycle. After the processing is completed, the output end of the electric hydraulic telescopic rod 41 is controlled to retract upward, and the driving plate 40 moves upward. The mechanical clamp 38 rotates around the inner wall of the groove 37 under the action of the spring shaft 39, gradually loosening the clamping of the flange, making it convenient to take out the processed flange; at the same time, the debris and waste slag received by the collecting plate 42 are cleaned.
