Description

Technical Field

[0001] This invention belongs to the field of metal pipe processing equipment, specifically a pipe cutting machine for processing stainless steel pipes. Background Technology

[0002] Stainless steel pipes need to be cut during processing to avoid inconvenience in transportation or inaccurate application length due to excessive pipe length. Generally, when cutting stainless steel pipes, the pipe body needs to be conveyed to the bottom of the pipe cutting machine first, and then the pipe body is cut by rotating the pipe body and pressing down the rotating cutting blade.

[0003] A patent document with announcement number CN217095962U discloses an automatic pipe cutting machine, including a fixed base, two guide rods and guide bars, and a movable seat. The top of the first fixed seat and the movable seat are equipped with limit wheels. Multiple rigid pipes and support seats are placed side by side on the upper surface of the two limit wheels. The top of the support seat is fixedly connected to a first cylinder, and the first cylinder is fixedly connected to a drive motor. The output shaft of the drive motor is fixedly connected to a saw blade. The upper surface of the second fixed seat is also equipped with a clamping mechanism, and the ends of the multiple rigid pipes are connected to the clamping mechanism.

[0004] In traditional techniques for cutting stainless steel pipes, the pipe is placed on top of two rotating, load-bearing wheels via a conveyor system. When cutting, the cutting tool is first positioned to contact the pipe and press down on it. Then, the rotating cutting tool cuts the rotating pipe. During this process, the pipe and the load-bearing wheels are in close contact. Over time, this can lead to damage to the outer circumference of the wheels. Furthermore, because the pipe is processed using the same method, the damage to the outer circumference of the load-bearing wheels may become identical after each replacement, requiring the entire wheel to be replaced after each failure, which is wasteful of resources. Additionally, traditional load-bearing structures lack features to improve airflow and facilitate material unloading, resulting in the presence of chips that can damage both the wheels and the pipe during rotational cutting.

[0005] Therefore, the present invention provides a pipe cutting machine for processing stainless steel pipes to solve the problems mentioned in the background art. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a pipe cutting machine for processing stainless steel pipes, including a frame and a pipe cutting box mounted on the frame. An angle adjustment mechanism is movably installed on the upper part of the inside of the pipe cutting box. A cutting tool is rotatably installed on the angle adjustment mechanism. A component groove is opened in the inner bottom of the pipe cutting box. Two bearing members are rotatably installed on the upper part of the inside of the component groove. Multiple installation mechanisms are installed above the component groove. Two corresponding installation mechanisms are used to install a set of corresponding bearing members. The bearing member includes a second metal block and two first metal blocks movably installed on both sides of the second metal block. The second metal block and the two first metal blocks are detachably installed. There is a gap between the second metal block and the two first metal blocks after installation. A cleaning mechanism is installed at the bottom of the component groove. The cleaning mechanism is used to perform suction work on the lower part of the two support components.

[0007] Preferably, a threaded groove is provided on one side of the metal block and a limiting slot is provided on the other side of the metal block.

[0008] Preferably, inserts are fixedly installed on both sides of the second metal block, and the inserts match the corresponding limiting slots. Sealing rings are also fixedly installed on both sides of the second metal block, and the sealing rings are arranged around the outside of the corresponding inserts.

[0009] Preferably, the installation mechanism includes multiple semicircular blocks fixedly installed on the pipe cutting box, a set of the bearing members being rotatably installed between two corresponding semicircular blocks, a rotating circular block being rotatably installed inside the semicircular block, and a threaded post being threaded inside the rotating circular block, the end of the threaded post matching the threaded groove.

[0010] Preferably, a sealing ring is fixedly installed on the side of the rotating block facing the support member. The diameter of the sealing ring is larger than the diameter of the threaded post, and the sealing ring is arranged around the outer side of the corresponding end of the threaded post.

[0011] Preferably, the cleaning mechanism includes two lifting barriers and two alignment suction strips fixedly installed at the bottom of the component groove. The two lifting barriers are respectively installed on the lower side of the two bearing members, and the two alignment suction strips are fixedly installed between the two lifting barriers.

[0012] Preferably, the cleaning mechanism further includes multiple air pipes fixedly installed on the outside of the tube cutting box, the multiple air pipes being connected to the inside of the component groove, a group of air pipes being connected to two alignment suction strips, and one end of the two air pipes being connected to an external suction device.

[0013] Preferably, the lifting barrier includes a U-shaped fixing strip and a suction component fixedly installed in the middle of the U-shaped fixing strip. Two metal hollow cylinders are also rotatably installed inside the U-shaped fixing strip. Multiple lifting columns are installed below the U-shaped fixing strip, and the lower ends of the multiple lifting columns are connected to the inner wall of the bottom of the component groove.

[0014] Preferably, the metal hollow cylinder has an internal cavity and a hollowed-out outer circumference. The hollowed-out portion is connected to the internal cavity of the metal hollow cylinder. An elastic barrier is fixedly installed on the side of the U-shaped fixing strip facing the middle of the component groove. The upper end of the elastic barrier is connected to the side of the U-shaped fixing strip, and the lower end of the elastic barrier is connected to the inner wall of the bottom of the component groove.

[0015] Preferably, the suction component includes a connecting block fixedly installed inside the middle position of the U-shaped fixing strip and a fixing cylinder fixedly installed above the connecting block. Cylindrical strips are fixedly installed on both sides of the fixing cylinder. A through groove is opened at one end of the metal hollow cylinder facing the fixing cylinder. The through groove is rotatably installed on the outer side corresponding to the cylindrical strip. The other end of the metal hollow cylinder is rotatably connected to the corresponding position of the U-shaped fixing strip. A connecting pipe is fixedly installed below the U-shaped fixing strip.

Gas chambers are opened inside both the connecting block and the fixing cylinder, and these gas chambers are connected to the cylindrical strips and the connecting pipe.

[0016] The beneficial effects of this invention are as follows: 1. The pipe cutting machine for processing stainless steel pipes according to the present invention uses a drive angle adjustment mechanism to drive the cutting tool to adjust the angle and press it down on the upper outer side of the pipe body. As the cutting tool is driven to rotate, the two support components and the pipe body follow the rotation under the action of friction. At this time, the cutting of the pipe body is completed by pressing down the rotating cutting tool. In this device, the support component is composed of two metal blocks, one and two. When the outer circumference of one of the structures of metal block one or metal block two is damaged, it can be disassembled and replaced separately, effectively reducing resource waste.

[0017] 2. The pipe cutting machine for stainless steel pipe processing described in this invention, when a metal block 1 is installed on both sides of a metal block 2, will have a certain gap. This gap can effectively increase air circulation, help heat dissipation, and allow chips and micro-dust impurities to fall off naturally through the gap, reducing the accumulation of chips and micro-dust impurities on the outside of the support component. In addition, a cleaning mechanism is also provided at the bottom of the component groove to suck up the space on the lower side of the support component to reduce chips and micro-dust impurities. Due to the existence of the gap between the installation of the two metal blocks 1 and 2, this suction force can act on chips and micro-dust impurities in more areas. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1-4As shown, an embodiment of the present invention provides a pipe cutting machine for processing stainless steel pipes, including a frame 2 and a pipe cutting box 1 mounted on the frame 2. An angle adjustment mechanism 3 is movably mounted on the upper part of the inside of the pipe cutting box 1. A cutting tool 4 is rotatably mounted on the angle adjustment mechanism 3. A component groove 5 is opened at the bottom inside the pipe cutting box 1. Two bearing members 6 are rotatably mounted on the upper part of the inside of the component groove 5. Multiple mounting mechanisms 7 are mounted on the upper part of the component groove 5. Two corresponding mounting mechanisms 7 are used to install a set of corresponding bearing members 6. The bearing member 6 includes a second metal block 62 and two first metal blocks 61 movably mounted on both sides of the second metal block 62. The second metal block 62 and the two first metal blocks 61 are detachably installed. After the metal round block 62 and the two metal round blocks 61 are installed, there is a gap. A cleaning mechanism 8 is installed at the bottom of the component groove 5. The cleaning mechanism 8 is used to perform suction work on the lower part of the two bearing components 6.

[0023] Specifically, when cutting the pipe, the pipe body is first positioned above and in the middle of the two support members 6, and in contact with the two support members 6. At this time, the cutting tool 4 is above the pipe body. The angle adjustment mechanism 3 drives the cutting tool 4 to adjust its angle and press down on the outer side of the pipe body. As the cutting tool 4 is driven to rotate, the two support members 6 and the pipe body rotate under the action of friction. At this time, the cutting tool 4 completes the cutting of the pipe body by pressing down on the rotating cutting tool 4. Because of this cutting method, there is a large bidirectional compressive force between the two support members 6 and the pipe body. If debris, dust and impurities generated during cutting enter the support members 6 or the outer side of the pipe body, the bidirectional compressive force may cause damage to the outer circumference of the support members 6 or the pipe body. If the outer circumference of the support members 6 is damaged, it will also affect the cutting of the next set of pipes. Moreover, since the pipes are usually processed by the same process, the outer circumference of the support members 6 may be damaged after rotation. The damage situation of the previous support component 6 is the same. After each damage, the entire support component 6 needs to be replaced, which is quite wasteful of resources. However, in this device, the support component 6 is composed of two metal circular blocks 61 and 62. When the outer circumference of a certain structure of metal circular block 61 or metal circular block 62 is damaged, it can be disassembled and replaced separately, effectively reducing resource waste. When the two metal circular blocks 61 are installed on both sides of metal circular block 62, there will be a certain gap. This gap can effectively increase air circulation, help heat dissipation, and allow chips and dust impurities to fall naturally through the gap, reducing the accumulation of chips and dust impurities on the outside of the support component 6. In addition, a cleaning mechanism 8 is also set at the bottom of the component groove 5 to suck up the space under the support component 6 to reduce chips and dust impurities. Due to the existence of the gap at the installation of the two metal circular blocks 61 and metal circular block 62, this suction force can act on chips and dust impurities in more areas.

[0024] like Figures 3-4 As shown, a threaded groove 611 is provided on one side of the metal block 61, and a limit slot 612 is provided on the other side of the metal block 61.

[0025] Both sides of the metal round block 62 are fixedly installed with insert blocks 621, which match the corresponding limiting slots 612. Both sides of the metal round block 62 are also fixedly installed with sealing rings 622, which surround the outer side of the corresponding insert blocks 621.

[0026] The mounting mechanism 7 includes multiple semicircular blocks 71 fixedly mounted on the pipe cutting box 1, a set of bearing members 6 rotatably mounted between two corresponding semicircular blocks 71, a rotating circular block 72 rotatably mounted inside the semicircular block 71, and a threaded post 73 threaded inside the rotating circular block 72, the end of the threaded post 73 matching the threaded groove 611.

[0027] A sealing ring 74 is fixedly installed on the side of the rotating block 72 facing the bearing 6. The diameter of the sealing ring 74 is larger than the diameter of the threaded post 73, and the sealing ring 74 is arranged around the outer side of the corresponding end of the threaded post 73.

[0028] Specifically, when the carrier 6 needs to be installed, first insert two metal blocks 61 into the two sides of metal block 62. At this time, the insert 621 is inserted into the inside of the limiting slot 612, and the two sealing rings 622 are tightly attached to the side of the corresponding metal block 61. Due to the setting of the sealing rings 622, there will be a gap when the two metal blocks 61 are installed on both sides of the metal block 62. This gap is annular groove, which can be used to increase air circulation. The presence of the cleaning mechanism 8 can suck away more chips and dust impurities. In addition, the setting of the gap annular groove also plays a V-shaped positioning role. When the outer surface of the pipe contacts the specific wheel section on the carrier 6, the side wall of the annular groove can support the pipe. To achieve a certain axial limiting effect, the pipe fitting is prevented from sliding left and right during the cutting process, ensuring the cutting accuracy. After the carrier 6 is assembled, it is placed in the spacing area between two corresponding semicircular blocks 71. At this time, the two corresponding sealing rings 74 contact the sides of the two corresponding metal blocks 61. By fixing and rotating the block 72, the corresponding threaded column 73 is screwed to make it threadedly connected with the corresponding threaded groove 611. The carrier 6 can be fixed by the installation mechanism 7. When the carrier 6 rotates, it can drive the rotating block 72, the threaded column 73 and the sealing rings 74 to rotate. The detachable structure makes it easy to install the carrier 6 and also facilitates the replacement of the carrier 6 parts with outer circumferential damage.

[0029] Example 2: Figure 3 and Figures 5-7As shown in the first embodiment, another embodiment of the present invention is as follows: the cleaning mechanism 8 includes two lifting barrier members 81 and two alignment suction strips 82 fixedly installed at the bottom of the component groove 5. The two lifting barrier members 81 are respectively installed on the lower side of the two bearing members 6, and the two alignment suction strips 82 are fixedly installed between the two lifting barrier members 81.

[0030] The cleaning mechanism 8 also includes multiple air pipes 83 fixedly installed on the outside of the pipe cutting box 1. The multiple air pipes 83 are connected to the inside of the component groove 5. One set of air pipes 83 is connected to two alignment suction strips 82. One end of the two air pipes 83 is connected to an external suction device.

[0031] The lifting barrier 81 includes a U-shaped fixing strip 811 and a suction component 813 fixedly installed in the middle of the U-shaped fixing strip 811. Two metal hollow cylinders 812 are also rotatably installed inside the U-shaped fixing strip 811. Multiple lifting columns 814 are installed below the U-shaped fixing strip 811, and the lower ends of the multiple lifting columns 814 are connected to the bottom inner wall of the component groove 5.

[0032] The metal hollow cylinder 812 has an internal cavity and its outer circumference is hollowed out. The hollowed-out part is connected to the internal cavity of the metal hollow cylinder 812. An elastic barrier 815 is fixedly installed on the side of the U-shaped fixing strip 811 facing the middle position of the component groove 5. The upper end of the elastic barrier 815 is connected to the side of the U-shaped fixing strip 811, and the lower end of the elastic barrier 815 is connected to the bottom inner wall of the component groove 5.

[0033] The suction component 813 includes a connecting block 8132 fixedly installed inside the middle position of the U-shaped fixing strip 811 and a fixing cylinder 8131 fixedly installed above the connecting block 8132. Cylindrical strips 8133 are fixedly installed on both sides of the fixing cylinder 8131. A metal hollow cylinder 812 has a through groove 8121 at one end facing the fixing cylinder 8131. The through groove 8121 is rotatably installed on the outside of the corresponding cylindrical strip 8133. The other end of the metal hollow cylinder 812 is rotatably connected to the corresponding position of the U-shaped fixing strip 811. A connecting pipe 816 is fixedly installed below the U-shaped fixing strip 811. The connecting pipe 816 is a telescopic air pipe structure. The upper end of the connecting pipe 816 extends through the U-shaped fixing strip 811 to the inside of the connecting block 8132. Gas chambers are opened inside both the connecting block 8132 and the fixing cylinder 8131, and these gas chambers are connected to the cylindrical strips 8133 and the connecting pipe 816.

[0034] Specifically, when the carrier 6 is working, the lifting column 814 drives the U-shaped fixing strip 811, the suction component 813, and the metal hollow cylinder 812 to rise until the outer sides of the two metal hollow cylinders 812 contact the outer circumference of the carrier 6. At this time, the two elastic barrier plates 815 are stretched and cooperate with the inner walls on both sides of the component groove 5, thus forming a sealed space. In this space, a set of air pipes 83 causes the two aligned suction strips 82 in this space to generate suction force. When the aligned suction strips 82 generate a relatively strong suction force, it can guide away the chips and dust impurities generated during the pipe cutting. Since the aligned suction strips 82 are correspondingly set directly below the gap annular groove of the first metal block 61 and the second metal block 62, the suction force through the two annular grooves can accelerate air circulation and help heat dissipation, and complete the suction work more quickly. Through another set of air pipes 83, it is connected to the connecting pipe 816, which can provide a more gentle suction force. This suction force passes through the connecting pipe 816. The connecting block 8132, the fixing cylinder 8131, the cylindrical strip 8133, and the through groove 8121 are released into the cavity of the metal hollow cylinder 812. When the metal hollow cylinder 812 rotates with the carrier 6, the traditional suction force of the connecting pipe 816 can carry away the micro dust and impurities in the area closest to the lower outer side of the carrier 6. These micro dust and impurities first enter the cavity of the metal hollow cylinder 812 through the hollow area and are finally released from the connecting pipe 816 and the corresponding air pipe 83. This suction force can also loosen the larger chips on the outer side of the carrier 6, causing them to fall into the interior below the component groove 5 and be transported away by the alignment suction strip 82. Through the setting of the cleaning mechanism 8, the cutting quality of the stainless steel pipe can be further enhanced. When different diameter carriers 6 are replaced to cut different pipes, the lifting column 814 can make the metal hollow cylinder 812 contact the outer side of the carriers 6 of different diameters to achieve the above effects. The elastic barrier 815 can create different near-sealed spaces according to different heights.

[0035] Working principle: When the carrier 6 needs to be installed, first insert two metal blocks 61 into the two sides of the metal block 62. At this time, the insert 621 is inserted into the inside of the limiting slot 612, and the two sealing rings 622 are tightly attached to the side of the corresponding metal block 61. Due to the setting of the sealing rings 622, there will be a gap when the two metal blocks 61 are installed on both sides of the metal block 62. This gap is annular groove, which can be used to increase air circulation. The presence of the cleaning mechanism 8 can suck away more chips and dust impurities. In addition, the setting of the gap annular groove also plays a V-shaped positioning role. When the outer surface of the pipe contacts the specific wheel section on the carrier 6, the side wall of the annular groove can play a certain axial limiting role on the pipe, preventing the pipe from sliding left and right during the cutting process. To ensure cutting accuracy, after the carrier component 6 is assembled, it is placed within the spacing area of ​​the two corresponding semicircular blocks 71. At this time, the two corresponding sealing rings 74 contact the sides of the two corresponding metal blocks 61. By fixing and rotating the block 72, and screwing the corresponding threaded post 73 to make it threadedly connected with the corresponding threaded groove 611, the carrier component 6 can be fixed by the mounting mechanism 7. When the carrier component 6 rotates, it can drive the rotating block 72, the threaded post 73 and the sealing rings 74 to rotate as well. The detachable structure facilitates the installation of the carrier component 6 and also makes it easy to replace the carrier component 6 parts with outer circumferential damage. When the carrier component 6 is working, the lifting column 814 drives the U-shaped fixing strip 811, the suction component 813 and the metal hollow cylinder 812 to rise. Until the outer sides of the two metal hollow cylinders 812 contact the outer circumference of the support 6, the two elastic barrier plates 815 are stretched and cooperate with the inner walls on both sides of the component groove 5, thus forming a sealed space. In this space, a set of air pipes 83 causes the two aligned suction strips 82 to generate suction force. When the aligned suction strips 82 generate a relatively strong suction force, they can guide away the chips and dust impurities generated during the pipe cutting. Because the aligned suction strips 82 are correspondingly set directly below the gap annular grooves of the first metal block 61 and the second metal block 62, the suction force through the two annular grooves can accelerate air circulation and help heat dissipation, and complete the suction work more quickly. It is connected to the connecting pipe 816 through another set of air pipes 83, which can be used for more... A gentle suction force is released into the cavity of the metal hollow cylinder 812 through the connecting pipe 816, connecting block 8132, fixing cylinder 8131, cylindrical strip 8133, and central groove 8121. When the metal hollow cylinder 812 rotates with the carrier 6, the conventional suction force of the connecting pipe 816 can remove micro-dust and impurities in the area closest to the lower outer part of the carrier 6. These micro-dust and impurities first enter the cavity of the metal hollow cylinder 812 through the hollow area and are finally released from the connecting pipe 816 and the corresponding air pipe 83. This suction force can also loosen larger chips on the outer side of the carrier 6, causing them to fall into the interior below the component groove 5 and be transported away by the alignment suction strip 82. Through the setting of the cleaning mechanism 8, the cutting quality of the stainless steel pipe can be further improved.When different diameter carrier components 6 are used to cut different pipes, the raising and lowering of the lifting column 814 allows the metal hollow cylinder 812 to contact the outer side of the carrier component 6 of different diameters, achieving the aforementioned effect. Furthermore, the elastic barrier plate 815 can create different near-sealed spaces depending on its height.
