Description

Technical Field

[0001] This utility model relates to the field of stainless steel flue processing technology, specifically to a residue cleaning structure and a steel pipe cutting device. Background Technology

[0002] Stainless steel flue pipes are used to connect with combustion equipment to allow flue gas to be discharged from the room. For ease of transportation, they are typically cut to lengths of about 1 meter. During installation, multiple stainless steel flue pipes are connected using a socket joint. Stainless steel flue pipes are mainly manufactured by a straight seam welded pipe forming machine that processes stainless steel sheets through rolling, straightening, welding, and cutting. Currently, there are two main methods for cutting steel pipes: laser cutting and abrasive cutting. Compared to abrasive cutting machines, laser cutting machines offer higher cutting efficiency and precision, and do not require regular abrasive disc replacement. Therefore, laser cutting machines are widely used in applications with high-frequency steel pipe cutting. However, the high-temperature slag generated during laser cutting can splash and adhere to the inner wall of the cut steel pipe, affecting subsequent processing and sealing during use.

[0003] Furthermore, in existing laser cutting machines, the laser head is fixedly mounted on the cutting equipment. Therefore, when cutting steel pipes, a clamping and rotating mechanism is needed to hold the steel pipe and drive it to rotate circumferentially so that the laser head can perform a circumferential cut. However, during the steel pipe processing, the formed steel pipe is still connected to the steel plate and cannot rotate. Therefore, the fixed laser head structure is not suitable for cutting steel pipes that have not yet been disconnected from the steel plate. Currently, steel pipes with a length of 8m-10m are first cut by a sandblasting machine, and then the 8m-10m steel pipes are transferred to the laser cutting machine. The conveying mechanism on the laser cutting machine transports the steel pipe to the clamping and rotating mechanism, which clamps the steel pipe and drives it to rotate circumferentially, thus enabling the laser head to perform a circumferential cut, cutting the steel pipe into short pipes with a length of 1m. In the above process, if the steel pipe is cut to a length of 1m directly using a sand cutting machine after it has just been formed, the frequency of the sand cutting machine stopping to replace the sand blades will increase, resulting in low cutting efficiency. In addition, some time is also spent in the process of transferring the steel pipe to the laser cutting machine, which will also lead to a decrease in work efficiency. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a residue cleaning structure, including a circumferential cutting device and a slag cleaning assembly located on one side of a straight seam welded pipe forming machine. The circumferential cutting device includes a base, a rotating disk, and a laser cutting head. The rotating disk is rotatably connected to the side of the base away from the straight seam welded pipe forming machine. The steel pipe formed by the straight seam welded pipe forming machine passes through the base and the rotating disk. The laser cutting head is connected to the rotating disk and rotates synchronously to perform circumferential cutting on the steel pipe that passes through the rotating disk and extends a specific length. The slag cleaning assembly includes a support frame, a slag suction pipe, and a fan. The fan is connected to the slag suction pipe to generate suction. The slag suction pipe is slidably connected to the support frame to be inserted into the steel pipe to absorb and clean the residue when the laser cutting head cuts the steel pipe.

[0005] Optionally, the slag suction pipe is a metal pipe, and the outer diameter of the slag suction pipe is smaller than the inner diameter of the steel pipe. When the steel pipe is not cut, the slag suction pipe is concentric with the steel pipe.

[0006] Optionally, the slag suction pipe is a pipe with openings at both ends, and the outer wall of the slag suction pipe is provided with a plurality of through holes spaced apart. The plurality of through holes are all located on the side of the slag suction pipe away from the blower and are all connected to the interior of the slag suction pipe. When the laser cutting head cuts the steel pipe, the plurality of through holes are all located at the cutting point of the steel pipe.

[0007] Optionally, the blower is a high-pressure suction blower, and a flexible hose is connected to the side of the suction pipe near the blower. The flexible hose is connected to and communicates with the blower. A collection box is provided on one side of the blower, and the collection box is communicated with the blower for storing the residue absorbed by the suction pipe.

[0008] Optionally, the support frame is equipped with a drive motor, the motor shaft of the drive motor is equipped with a transmission gear, a spur rack is slidably mounted on the support frame, the slag suction pipe is connected to the spur rack and moves synchronously, and the transmission gear meshes with the spur rack.

[0009] Optionally, a sleeve is fixedly installed on the base, and the steel pipe formed by the straight seam welded pipe forming machine is inserted into the sleeve and moves within the sleeve; the rotating disk is rotatably mounted on the sleeve, and a rotating motor is provided in the base, which is connected to the rotating disk to drive the laser cutting head to rotate.

[0010] Optionally, a baffle plate is fixed on the support frame. When the steel pipe is cut and the slag suction pipe moves away from the base, the end of the steel pipe away from the base is adapted to abut against the baffle plate, driving the slag suction pipe to be completely pulled out from the inside of the steel pipe, so that the steel pipe falls and achieves automatic material discharge.

[0011] Optionally, the support frame is provided with a feeding plate, which is inclined on the support frame. The slag suction pipe is completely pulled out from inside the steel pipe, and the steel pipe falls onto the feeding plate and automatically rolls down to discharge the slag.

[0012] Optionally, the residue cleaning structure also includes a frame, wherein the base and the support frame are slidably connected to the frame, and a drive assembly is provided on the frame to drive the base and the support frame to move; when the laser cutting head cuts the steel pipe, the straight seam welded pipe forming machine still drives the steel pipe to move, and the drive assembly drives the base and the support frame to move synchronously relative to the frame, so that the laser cutting head and the steel pipe remain relatively stationary.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. The rotary disc can drive the laser cutting head to rotate around the steel pipe as the rotation axis to perform circumferential cutting on the steel pipe. The steel pipe does not need to rotate during the cutting process. After the steel pipe is formed by the straight seam welded pipe forming machine, it can be circumferentially cut in time without the need for additional transportation and frequent machine stops, which improves work efficiency. In addition, during cutting, the slag suction pipe can be inserted into the cutting point inside the steel pipe to suck away the slag generated during cutting. It is not easy for the high-temperature slag generated during the cutting process to adhere to the inner wall of the steel pipe, which would affect the subsequent processing of the steel pipe and the sealing performance during use, thus improving the quality of the steel pipe after cutting.

[0015] 2. After the slag suction pipe is inserted into the cut inside the steel pipe, the multiple through holes in the circumferential direction of the slag suction pipe are arranged circumferentially inside the steel pipe. The slag and flue gas generated at each position during the circumferential cutting of the steel pipe by the laser cutting head can be absorbed, and the residue is cleaned relatively well.

[0016] 3. After the laser cutting head cuts the steel pipe, the steel pipe will first fall onto the slag suction pipe. Then, as the slag suction pipe moves away from the laser cutting head, the steel pipe will automatically fall off the slag suction pipe under the action of the baffle plate. The slag suction pipe not only plays the role of adsorbing slag, but also plays a buffering role during the process of the steel pipe falling after being cut.

[0017] 4. To ensure the continuity of welding of rolled circular steel pipes by the straight seam welded pipe forming machine, the straight seam welded pipe forming machine continuously drives the formed steel pipe to move. When cutting the steel pipe, the drive component on the frame can drive the base to drive the laser cutting head and the support frame to drive the slag suction pipe to move synchronously with the steel pipe, maintaining a relatively static state. This makes the surface of the steel pipe cut by the laser cutting head relatively flat and the cutting quality high.

[0018] In addition, this utility model provides a steel pipe cutting device, including the residue cleaning structure described above.

[0019] Compared with the prior art, the steel pipe cutting device of this utility model and the residue cleaning structure described above have the same advantages over the prior art, which will not be repeated here. Attached Figure Description

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-6 This application will be described in further detail.

[0028] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0029] In a first aspect, this utility model embodiment provides a residue cleaning structure, referring to... Figure 1The residue cleaning structure includes a circumferential cutting device 1, a slag cleaning component 2, and a frame 3, all located on one side of the straight seam welded pipe forming machine (a prior art technology for processing steel pipes, details of which will not be elaborated here). The straight seam welded pipe forming machine is used to roll, straighten, and weld stainless steel sheets to form steel pipes. Both the circumferential cutting device 1 and the slag cleaning component 2 are slidably mounted on top of the frame 3. The steel pipe formed by the straight seam welded pipe forming machine can be directly inserted into the circumferential cutting device 1, and after passing through the circumferential cutting device 1, it is suspended and extended under the conveying of the straight seam welded pipe forming machine. The circumferential cutting device 1 can perform circumferential cutting on the steel pipe that has passed through the circumferential cutting device 1 and extended to a specified length according to the program settings. The slag cleaning component 2 is located on the side of the circumferential cutting device 1 away from the straight seam welded pipe forming machine. When the circumferential cutting device 1 cuts the steel pipe, the slag cleaning component 2 can be inserted into the cut steel pipe and located at the cutting point to absorb and clean the residue generated during the cutting process.

[0030] Reference Figure 1 and Figure 2 The circumferential cutting equipment 1 includes a base 11, a rotating disk 12, and a laser cutting head 13. The rotating disk 12 is rotatably connected to the side of the base 11 away from the straight seam welded pipe forming machine. The steel pipe formed by the straight seam welded pipe forming machine passes through the base 11 and the rotating disk 12. The laser cutting head 13 is connected to the rotating disk 12 and rotates synchronously to perform circumferential cutting on the steel pipe that passes through the rotating disk 12 and extends to a specific length.

[0031] Reference Figures 1 to 3 A sleeve 111 is fixedly installed inside the base 11, with the axial direction of the sleeve 111 being left and right; both ends of the sleeve 111 protrude from the base 11. The steel pipe formed by the straight seam welded pipe forming machine is directly inserted into the sleeve 111, and the steel pipe can move towards the slag cleaning component 2 under the drive of the straight seam welded pipe forming machine. The inner wall of the sleeve 111 is provided with a flexible component, and the outer peripheral wall of the steel pipe is in contact with the flexible component, reducing the risk of scratches on the outer wall of the steel pipe. The sleeve 111 and the base 11 provide guidance and support for the steel pipe.

[0032] The rotating disk 12 is rotatably mounted on the portion of the sleeve 111 that protrudes from the base 11. A fixed sleeve 112 and a rotating sleeve 113 are fitted onto the sleeve 111. The fixed sleeve 112 is located on the side of the rotating sleeve 113 furthest from the slag cleaning assembly 2 and is fixedly connected to the sleeve 111 by bolts. A rotating bearing is inserted into the rotating sleeve 113 and is fitted onto the sleeve 111. An end cap is integrally formed on the end of the rotating sleeve 113 near the fixed sleeve 112. The outer diameter of the end cap is larger than the outer diameter of the rotating sleeve 113 but smaller than the outer diameter of the fixed sleeve 112. A retaining ring 114 is fitted onto the side of the fixed sleeve 112 near the rotating sleeve 113 and fixed with bolts. The retaining ring 114 has an L-shaped cross-section, and the end cap is located inside the retaining ring 114. The retaining ring 114 limits the axial movement of the end cap and the rotating sleeve 113 but does not interfere with the rotation of the end cap and the rotating sleeve 113. The rotating disk 12 is fixed to the end of the rotating sleeve 113 away from the end cover by bolts, so that the rotating disk 12 can rotate synchronously with the rotating sleeve 113. A rotary motor 14 is installed inside the base 11. A drive gear is keyed to the motor shaft of the rotary motor 14. A driven gear is sleeved and fixedly connected to the rotating sleeve 113. The drive gear and the driven gear mesh with each other. In this way, the rotary motor 14 can drive the rotating disk 12 to rotate, but the rotating disk 12 will not move along its own axial direction.

[0033] Reference Figures 1 to 3 The laser cutting head 13 is bolted to the side of the rotating plate away from the base 11. To prevent the cable on the laser cutting head 13 from getting tangled when the rotating disk 12 rotates, the rotary motor 14 drives the rotating disk 12 to move back and forth. That is, when cutting the first section of steel pipe, the rotary motor 14 drives the rotating disk 12 to rotate in the forward direction; when cutting the second section of steel pipe, the rotary motor 14 drives the rotating disk 12 to rotate in the reverse direction, and so on.

[0034] Reference Figures 1 to 4 The slag cleaning assembly 2 includes a support frame 21, a slag suction pipe 22, and a blower 23. The blower 23 is connected to the slag suction pipe 22 to generate suction. The slag suction pipe 22 is slidably connected to the support frame 21 to be inserted into the steel pipe to absorb and clean the residue when the laser cutting head 13 cuts the steel pipe. The support frame 21 is slidably connected to the frame 3. When the support frame 21 moves relative to the frame 3, the slag suction pipe 22 will move synchronously with the support frame 21 relative to the frame 3.

[0035] The slag suction tube 22 is a tube open at both ends. Since the residue generated during the cutting process has a certain temperature, the slag suction tube 22 is made of metal. Compared with hard plastic materials, the temperature generated by the laser cutting head 13 during cutting is less likely to melt the metal slag suction tube 22, and the hot residue is less likely to adhere to the inner wall of the slag suction tube 22.

[0036] Reference Figures 1 to 4The outer diameter of the suction pipe 22 is smaller than the inner diameter of the steel pipe. When the steel pipe is not cut, the suction pipe 22 is concentric with the steel pipe. On the one hand, this allows sufficient space inside the steel pipe for air to flow, enabling the suction pipe 22 to generate suction. On the other hand, the concentric arrangement ensures that the suction force formed by the suction pipe 22 and the steel pipe at various circumferential positions is relatively uniform, which helps to adsorb residues at various locations.

[0037] Reference Figure 4 and Figure 5 The outer wall of the slag suction pipe 22 is provided with multiple through holes 221 spaced apart circumferentially. All through holes 221 are located on the side of the slag suction pipe 22 away from the blower 23 and are connected to the interior of the slag suction pipe 22. The diameter of each through hole 221 is larger than the width of the laser cutting head 13 during cutting. When the laser cutting head 13 cuts the steel pipe, all through holes 221 are located at the cutting point, and the cutting width of the laser cutting head 13 is within the range of the diameter of each through hole 221. During cutting, the through holes 221 can directly generate suction towards the inner wall of the steel pipe, allowing the slag and flue gas generated at each location during the circumferential cutting process to be absorbed, resulting in relatively clean residue removal.

[0038] Reference Figures 1 to 5 In this embodiment, the preferred blower 23 is a high-pressure suction blower 23 (existing technology, with an air intake and an air outlet; detailed structure will not be elaborated further). This enables the slag suction pipe 22 to generate sufficient suction to adsorb and discharge the residue. The high-pressure suction blower 23 is fixedly installed on the ground. A flexible hose 24 is fitted onto the side of the slag suction pipe 22 near the blower 23. The flexible hose 24 is fixedly connected to and communicates with the slag suction pipe 22 via a hose clamp. The other end of the flexible hose 24 is connected to and communicates with the air intake of the high-pressure suction blower 23 via a hose clamp. During the movement of the slag suction pipe 22, the length of the flexible hose 24 has a margin, allowing the slag suction pipe 22 to move freely. A collection box 25 is placed on the ground next to the high-pressure suction blower 23. The collection box 25 is connected to and communicates with the air outlet of the high-pressure suction blower 23 via a pipe. The suction force generated by the suction pipe 22 will first adsorb the residue inside itself. During the adsorption process, the negative pressure airflow will cool the residue. The residue will not stick to the inner wall of the suction pipe 22, but will pass through the hose 24, the air inlet and outlet of the high-pressure suction blower 23 in sequence and enter the collection box 25 for temporary storage. After the work is completed for a day, the residue in the collection box 25 will be processed in a unified manner.

[0039] A sliding groove is provided on the support frame 21, with its length direction running horizontally along the support frame 21 and its top open. The sliding groove is coated with grease, and a rack 26 is slidably mounted within it. The rack 26 has integrally formed blocking strips on its front and rear outer walls. Limiting grooves are provided on the corresponding two groove walls of the sliding groove, with their length direction aligned with that of the sliding groove. The blocking strips are inserted into and slide within the limiting grooves. The cooperation between the blocking strips and the limiting grooves prevents the rack 26 from disengaging vertically from the sliding groove, improving its stability during horizontal sliding. A drive motor 27 is bolted to the support frame 21. A transmission gear is keyed to the motor shaft of the drive motor 27, meshing with the rack 26. The drive motor 27 drives the transmission gear to rotate, which in turn moves the rack 26. The suction pipe 22 is clamped and fixed with fixing blocks by bolts. These fixing blocks are all fixedly connected to the rack 26 by bolts. Thus, when the rack 26 moves, it drives the suction pipe 22 to move, allowing the suction pipe 22 to be inserted into the steel pipe for suction or to detach from the steel pipe. The suction pipe 22 is relatively lightweight, so even if it is fixed by only one fixing block, the end of the suction pipe 22 will not sag or shift. Alternatively, a support member is fixed to the support frame 21 by bolts. The support member and the fixing blocks are arranged at intervals, and the side of the suction pipe 22 away from the support block abuts against the top of the support member for support.

[0040] Reference Figures 1 to 5 A baffle plate 28 is bolted to the support frame 21. The baffle plate 28 is located on the side of the rotating disk 12 closest to the suction pipe 22 and is spaced apart from the rotating disk 12. The baffle plate 28 does not interfere with the movement of the suction pipe 22. When the suction pipe 22 is not inserted into the steel pipe, it is located on the side of the baffle plate 28 away from the rotating disk 12. After the steel pipe is cut, it will fall onto the suction pipe 22. As the suction pipe 22 moves away from the base 11, the steel pipe will move backward synchronously with it. Then, the end of the steel pipe away from the base 11 is suitable to abut against the baffle plate 28, but the suction pipe 22 can continue to move, driving the suction pipe 22 to be completely pulled out from the inside of the steel pipe, so that the steel pipe falls and achieves automatic feeding.

[0041] A discharge plate 29 is fixedly connected to the rear side of the support frame 21. The discharge plate 29 is inclined on the support frame 21, that is, the distance from the end of the discharge plate 29 away from the support frame 21 to the ground is less than the distance from the end of the discharge plate 29 closer to the support frame 21 to the ground. The suction pipe 22 is completely pulled out from inside the steel pipe, and the steel pipe falls onto the discharge plate 29 and automatically rolls down for discharge. A conveyor is provided at the end of the discharge plate 29 away from the support frame 21. The steel pipe rolls from the discharge plate 29 onto the conveyor and is transported to the next workstation for processing.

[0042] Reference Figures 1 to 6 Assuming the moving direction of the steel pipe and the moving direction of the circumferential cutting equipment 1 and the slag cleaning component 2 on the frame 3 are left and right, then two sets of guide rail groups 31 are spaced apart on the top of the frame 3 along the front-back direction. The following description uses the structure of one set of guide rail group 31 as an example. The guide rail group 31 includes a linear guide rail and a slider. The linear guide rail is fixedly connected to the frame 3 by bolts. The slider slides directionally on the linear guide rail. Multiple sliders are spaced apart on the linear guide rail. Some sliders are bolted to the base 11; some sliders are bolted to the support frame 21, thereby enabling the circumferential cutting equipment 1 and the slag cleaning component 2 to move relative to the frame 3 in the left and right direction.

[0043] Reference Figures 1 to 6 The frame 3 is equipped with a drive assembly 32 for moving the base 11 and support frame 21. The drive assembly 32 includes a servo motor and a rack. The servo motor is fixedly connected to the frame 3 by bolts, and a gear is keyed to the motor shaft of the servo motor. Multiple sliders are fixedly connected to the rack by bolts, and the gear meshes with the rack. After the servo motor drives the gear to rotate, the gear will drive the rack to move the base 11 and support frame 21. To ensure the continuity of welding of rolled circular steel pipes by the straight seam welded pipe forming machine, the straight seam welded pipe forming machine will continuously drive the formed steel pipe to move. When cutting the steel pipe, the drive assembly 32 on the frame 3 can drive the base 11 to drive the laser cutting head 13 and the support frame 21 to drive the slag suction pipe 22 to move synchronously with the steel pipe, maintaining a relatively stationary state. This makes the surface of the steel pipe cut by the laser cutting head 13 relatively flat and the cutting quality high.

[0044] The implementation principle of the residue cleaning structure in this application embodiment is as follows: After the steel pipe is formed by the straight seam welded pipe forming machine, it can be directly inserted into the sleeve 111, and after passing through the base 11 and the rotating disk 12, it extends out to a specific length. When the laser cutting head 13 cuts the steel pipe extending out to a specific length, the servo motor drives the base 11 and the support frame 21 to move along the moving direction of the steel pipe, so that the laser cutting head 13 and the steel pipe remain relatively stationary, making the surface of the steel pipe cut by the laser cutting head 13 relatively flat. Then, the slag suction pipe 22 is inserted into the cut part inside the steel pipe, and the rotating disk 12 drives the laser cutting head 13 to rotate, making a circumferential cut on the steel pipe. The slag suction pipe 22 can suck away the slag generated during the cutting. After the laser cutting head 13 cuts the steel pipe, the steel pipe will first fall onto the slag suction pipe 22. Then, as the slag suction pipe 22 moves away from the laser cutting head 13, the steel pipe will automatically fall from the slag suction pipe 22 onto the feed plate 29 under the action of the baffle plate 28, and roll down onto the conveyor through the inclination of the feed plate 29. During this process, the servo motor drives the base 11 and the support frame 21 to reset, in preparation for the next cut, and so on.
