Description

Technical Field

[0001] The present invention relates to the technical field of laser tube cutting, in particular to a laser tube cutting machine with an adaptive end slag cleaning mechanism. Background Art

[0002] In the field of laser tube cutting technology, laser cutting is widely used in the processing of various metal tubes due to its high efficiency and precision. However, the slag problem generated during the laser cutting process has always been one of the key factors restricting cutting quality. Especially when cutting materials such as stainless steel containing elements such as chromium and nickel that easily increase the viscosity of the slag, the slag is more likely to adhere to the inner wall of the tube, forming dross, which seriously affects the flatness of the cut surface and the quality of subsequent processing.

[0003] In the prior art, a common method for addressing the slag problem during laser tube cutting is to use a dust extraction duct. For example, the utility model patent CN217727512U, "A device for solving slag accumulation during laser tube cutting," utilizes a slag collecting rod to collect slag during the cutting process to reduce slag adhesion to the inner wall of the tube. However, while this method can effectively collect most of the slag, it has limited effectiveness in cleaning residual slag that is splashed onto other locations on the inner wall of the tube during the cutting process. This results in the need for inspection and secondary slag treatment of the tube after cutting, which is time-consuming and labor-intensive.

[0004] To this end, we propose a laser tube cutting machine with an adaptive end slag cleaning mechanism. Summary of the Invention

[0005] The object of the present invention is to provide a laser tube cutting machine with an adaptive end slag cleaning mechanism to solve the problems mentioned in the background art;

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a laser tube cutting machine with an adaptive end slag cleaning mechanism, comprising a cutting frame, a storage frame, and a transmission frame, with the cutting frame as the center, the storage frame being installed on one side, and the transmission frame being installed on the other side, characterized in that a laser cutting assembly is installed on the cutting frame, a clamping and rotating assembly is installed on the cutting frame, and a movable cover is slidably connected to the top of the storage frame;

[0007] The top of the movable cover is slidingly connected to the transmission assembly, and a positioning plate is installed on the transmission assembly, and a claw block is evenly slidably connected to the outer wall of the movable cover by a bolt. The outer wall of the movable cover is fixed to the transmission box by a bolt. One side of the transmission box is movably connected to a rotary sleeve, and one side of the rotary sleeve passes through the positioning plate and is slidably connected to the rotary sleeve. The positioning post is sleeved with a fixed limiting sleeve, and the outer support plate is symmetrically and slidably connected to the outer support plate on the outer wall of the rotary sleeve. The friction block is fixedly connected to the inner wall of the rotary sleeve and is correspondingly rotatably connected to the outer support plate. The ball movably connected at the end of the tilting arm is rolledly connected to the limiting sleeve, and the other end of the tilting arm is slidably connected to the outer support plate, and a residue collecting groove is provided on the outer wall of the rotary sleeve.

[0008] Furthermore, a gear is installed in the transmission box and on the rotating sleeve, a transmission gear shaft and an abutment ring are movably connected in the transmission box, and a gear is fixed on the abutment ring side, a gear is installed on one side of the transmission gear shaft and is meshed with the gear on the rotating sleeve, and a gear is installed on the other side and is meshed with the gear on the abutment ring.

[0009] Furthermore, a rocker arm is rotatably connected inside the transmission box and located on the opposite side of the rotating sleeve and the abutment ring. One side of the rocker arm abuts against the side wall of the abutment ring, and the other side abuts against the positioning column. The positioning column is located inside the rotating sleeve and is provided with a fixed limiting cylinder. The positioning column is located at one end of the rotating sleeve and is abutted against a spring.

[0010] Furthermore, a sealing ring is installed on the inner wall of the rotary sleeve and on the side of the limiting cylinder. The inner wall of the sealing ring is evenly slidably connected to an outer support block, and one end of the outer support block passes through the rotary sleeve and is installed with a ball. The outer support block is located inside the sealing ring and is sleeved with a spring, and the outer wall of the limiting cylinder is in contact with the outer support block.

[0011] Furthermore, a material receiving trolley is slidably connected to the bottom of the material storage rack, and a limited position flow channel is fixed on the material storage rack by bolts.

[0012] Furthermore, a guide assembly is installed on the side wall of the transmission frame, and a pushing assembly is slidably connected to the transmission frame and located on the side of the guide assembly.

[0013] The laser tube cutting method with an adaptive end slag cleaning mechanism is as follows:

[0014] During cutting, slag is collected, and one end of the stainless steel pipe placed on the guide assembly is clamped by the pushing assembly, which pushes the other end of the stainless steel pipe to contact the clamping and rotating assembly on the cutting frame. The single cutting length of the stainless steel pipe is set, and the movable cover on the storage rack side is controlled to move. As the pushing assembly moves, the moving stainless steel pipe abuts against the positioning plate side of the transmission assembly. At the same time, the motor in the transmission assembly rotates, controlling multiple groups of claw blocks to contact one end of the stainless steel pipe. As the clamping and rotating assembly rotates, the laser cutting assembly on the cutting frame adjusts the focus position, and the stainless steel pipe rotates while cutting;

[0015] The slag is cleaned during grinding, and multiple groups of claw blocks on the transmission assembly complete the clamping of one end of the stainless steel pipe. At the same time, the motor in the transmission box drives the transmission gear shaft to rotate. The rotary sleeve rotates on the inner wall of the stainless steel pipe while the abutment ring contacts the rocker arm and squeezes the positioning column. The positioning column slides and squeezes the outer support block and the tilting arm through the limit cylinder and the limit sleeve. The tilting arm rotates and squeezes the friction block on the outer support plate to contact the inner wall of the cut stainless steel pipe, and the rotary sleeve rotates as a whole to achieve grinding and cleaning of the slag on the inner wall of the stainless steel pipe. After cleaning, the transmission assembly and the movable cover slide to push the cut stainless steel pipe on the outside of the rotary sleeve into the limiting flow channel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the laser tube cutting machine innovatively provides a residue collection groove on the top of the rotary sleeve, which effectively collects the slag generated during the cutting process and significantly reduces the interference of the slag on the cutting process. More importantly, after the cutting is completed, the rotary sleeve can rotate and drive the friction block on the outer support plate to contact and grind the inner wall of the cut stainless steel tube, thereby completely removing the residual slag. The application of this mechanism greatly improves the cutting quality of the laser tube cutting machine, avoids problems such as uneven tube wall and dimensional deviation caused by residual slag, and ensures that the cut tube can meet high quality requirements.

[0018] 2. In the present invention, the rotary sleeve design in the adaptive end slag cleaning mechanism shows a high degree of adaptability. It can flexibly adjust the position of the outer support plate and the friction block according to the diameter and wall thickness of different pipes to ensure that the slag can always be effectively contacted and cleaned. This design enables the laser tube cutting machine to easily meet the cutting needs of pipes of different specifications and materials, greatly enhancing the versatility and flexibility of the equipment. At the same time, the mechanism is closely integrated with the overall control system of the laser tube cutting machine to realize the automation of processes such as cutting and slag cleaning. This not only reduces manual intervention and labor intensity, but also significantly improves production efficiency, reduces operational errors caused by human factors, and further improves product quality.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-9 , the present invention provides a technical solution:

[0031] Example 1: The present invention discloses a laser tube cutting machine with an adaptive end slag cleaning mechanism. The laser tube cutting machine includes a cutting frame 1, a storage frame 2, and a transmission frame 3. The cutting frame 1 is centered, with the storage frame 2 installed on one side and the transmission frame 3 installed on the other side. The cutting frame 1 is equipped with a laser cutting assembly 4 and a clamping and rotating assembly 5. The top of the storage frame 2 is slidably connected to a movable cover 6.

[0032] In specific implementation, Figure 1 and Figure 2 As shown, the modular functional areas are defined. The transmission frame 3 is used to place and push the cut pipes, the cutting frame 1 is used for pipe clamping, rotation and laser cutting, and the storage rack 2 is used to clean the slag on the inner wall of the pipe after cutting and to store and collect the cut pipes. Each rack performs its own function, improving the overall pipe cutting efficiency and quality.

[0033] There are many reasons for the presence of slag during laser cutting of pipes. The amount of slag generated can be reduced by adjusting the cutting air pressure, laser focus, and cutting rate. However, the composition of some pipe materials is limited, similar to the chromium and nickel elements in stainless steel, which will increase the viscosity of the slag. This problem cannot be limited by adjustment. Therefore, a movable rotary sleeve 15 is provided to collect the slag on the inner wall during the cutting process. In the prior art, the rotary sleeve 15 is defined as a dust extraction pipe. This method is efficient and simple in slag removal. However, considering that some slag sputters during the cutting process, collection is the core technology, and the residual slag is processed by friction grinding to further improve the processing quality of the laser cut pipe body.

[0034] like Figure 4 and Figure 5 As shown, the top inner wall of the movable cover 6 is slidably connected with a transmission component 11, and a positioning plate 12 is installed on the transmission component 11, and a claw block 13 is evenly slidably connected in the groove on one side of the positioning plate 12. The transmission component 11 is configured to adapt to the length of the cutting pipe. The positioning plate 12 on the transmission component 11 can slide on the outer wall of the rotary sleeve 15. When the pushing component 8 realizes the movement of the pipe, after contacting the positioning plate 12, the distance between the positioning plate 12 and the laser cutting component 4 is the length of the cutting pipe, which realizes the adjustment of the cutting pipe length. Correspondingly, a material receiving trolley 9 is provided at the bottom of the material storage rack 2. For short-distance pipe cutting, the cutting material is discharged into the material receiving trolley 9, and for long-distance pipe cutting, to avoid clogging of the cutting pipe, the following method is used. Figure 4 The limiting flow channel 10 shown is used to constrain movement;

[0035] like Figure 5As shown, the outer wall of the movable cover 6 is fixed with a transmission box 14 by bolts, and a rotary sleeve 15 is movably connected to one side of the transmission box 14. One side of the rotary sleeve 15 passes through the positioning plate 12 and is slidably connected thereto. The installation of the rotary sleeve 15 is used for automatic inner wall grinding after cutting the pipe. For this purpose, the initial adjustment of the pipe cutting is that the pipe diameter is larger than the diameter of the rotary sleeve 15.

[0036] At the same time, the relevant components are installed on the rotary sleeve 15. Figure 5 Understand, the top is provided with a residue collection groove 27, and friction blocks 25 are installed in the grooves on both sides. Figure 7 and Figure 8 As shown, a positioning column 19 is slidably connected to the rotary sleeve 15, and a fixed limiting sleeve 23 is sleeved on the positioning column 19. In order to effectively clean the slag on the end of the pipe, an outer support plate 24 is symmetrically slidably connected on the outer wall of the rotary sleeve 15 and located on the side of the limiting sleeve 23. A friction block 25 is fixedly connected to the outer support plate 24. A tilting arm 26 is correspondingly rotatably connected to the inner wall of the rotary sleeve 15 and located on the side of the outer support plate 24. The ball movably connected at the end of the tilting arm 26 is rollingly connected to the limiting sleeve 23, and the other end of the tilting arm 26 is slidably connected to the outer support plate 24. When the positioning column 19 drives the limiting sleeve 23 to slide, When the pipe is cut, the moving limit sleeve 23 drives the tilting rod to rotate, and the lever action of the tilting arm 26 can drive the outer support plate 24 to expand outward, so that the friction block 25 is close to the inner wall of the pipe. Subsequently, the rotary sleeve 15 rotates, and the friction block 25 rotates and grinds along the slag side of the inner wall of the pipe, completing the automatic grinding process after the inner wall of the pipe is cut. The moving spacing of the positioning column 19 controls the outward push distance of the friction block 25, effectively solving the problem of friction damage to the inner wall of the pipe during the process. Similarly, the rotary sleeve 15 rotates, and the ball at one end of the tilting rod rotates along the limit sleeve 23, and the movement is not restricted, and finally the end slag is effectively removed.

[0037] like Figure 6 As shown, when the pipe is cut, the entire rotary sleeve 15 remains stationary, and the center of the residue collection groove 27 faces the laser cutting focus position. Most of the slag generated during the cutting process enters the residue collection groove 27. Figure 7 Combine Figure 5 , a notch is provided at the end of the rotary sleeve 15 and is connected to the residue collecting tank 27, and the residue collecting tank 27 is subsequently cleaned through the notch;

[0038] Regarding the driving of the positioning column 19 and the rotary sleeve 15, a gear is installed in the transmission box 14 and on the rotary sleeve 15. A transmission gear shaft 16 and an abutment ring 17 are movably connected in the transmission box 14, and a gear is fixed on the side of the abutment ring 17. A gear installed on one side of the transmission gear shaft 16 is meshed with a gear on the rotary sleeve 15, and a gear installed on the other side is meshed with a gear on the abutment ring 17. When the transmission gear shaft 16 rotates, it can simultaneously drive the rotary sleeve 15 and the abutment ring 17 to rotate;

[0039] A rocker 18 is rotatably connected to the transmission box 14 and is located on the opposite side of the rotary sleeve 15 and the abutment ring 17. One side of the rocker 18 abuts against the side wall of the abutment ring 17, and the other side abuts against the positioning column 19. Figure 9 As shown, when the abutment ring 17 rotates, one side of the ring surface contacts the rocker rod 18 and pushes the rocker rod 18 to rotate, thereby pushing the positioning column 19 to move in the rotary sleeve 15. On the contrary, without the rocker rod 18 abutting, the spring at its end pushes the positioning column 19 to return to its original position. Therefore, by rotating the transmission gear shaft 16, the rotary sleeve 15 can be rotated and the positioning column 19 can be moved. At the same time, the moving distance of the positioning column 19 can be adjusted by replacing the abutment ring 17.

[0040] like Figure 7 As shown, the positioning column 19 is located in the rotary sleeve 15 and is sleeved with a fixed limiting cylinder 20. A sealing ring 21 is installed on the inner wall of the rotary sleeve 15 and on the side of the limiting cylinder 20. The inner wall of the sealing ring 21 is evenly slidably connected with an outer support block 22, and one end of the outer support block 22 passes through the rotary sleeve 15 and is installed with a ball. The outer support block 22 is located in the sealing ring 21 and is sleeved with a spring. The outer wall of the limiting cylinder 20 abuts against the outer support block 22. When the positioning column 19 moves, it can push the outer support block 22 to expand outward, so that the ball is close to the inner wall of the pipe, thereby achieving inner wall support during pipe cutting and subsequent grinding, and improving the overall pipe processing effect.

[0041] When specifically processing the slag on the inner wall of the pipe, after cutting, one end of the pipe is clamped by the claw block 13 on the positioning plate 12, the positioning column 19 moves to the left, the limit cylinder 20 first contacts the inner wall of the pipe, and then continues to squeeze the tilt arm 26 to achieve the contact between the friction block 25 on the side of the outer support plate 24 and the inner wall of the pipe. While rotating, the friction block 25 completes the cleaning of the inner wall of the pipe in the cutting area, and then the transmission assembly 11 cooperates with the movable cover 6 to push the cut pipe on the rotary sleeve 15 away.

[0042] Example 2: Based on Example 1, this example optimizes some structures of the laser tube cutting machine to improve the degree of automation of the laser tube cutting machine. This example also adds a control system, which can achieve precise control of components such as the laser cutting assembly 4, the clamping and rotating assembly 5, and the transmission assembly 11, thereby realizing automatic loading, clamping, cutting, slag cleaning, and unloading of the tube;

[0043] In order to achieve precise control of the pipe rotation speed, the clamping and rotating assembly 5 adopts a servo motor drive mode. By adjusting the speed of the servo motor, the pipe rotation speed can be precisely controlled to meet the requirements of different cutting processes.

[0044] In addition, in order to improve the safety performance of the laser tube cutting machine, this embodiment also adds a safety protection device, which includes components such as a safety grating and an emergency stop button, which can effectively protect the operator and prevent accidents.

[0045] The guide assembly 7 and the push assembly 8 installed on the side of the transmission frame 3 are synchronously controlled to facilitate the guidance and movement of pipes of different sizes before cutting, further improving the overall pipe cutting efficiency.
