Technical Field
[0001] This invention belongs to the technical field of steel pipe processing, specifically relating to a cutting device for processing seamless steel pipes with dustproof function. Background Technology
[0002] In existing seamless steel pipe processing technologies, cutting devices, as key equipment, are widely used in pipe manufacturing, construction engineering, and machining. When operators cut steel pipes, they typically use a circular saw to make contact with the pipe. However, during this process, the friction between the high-speed rotating saw blade and the steel pipe generates a large amount of metal dust and debris. This dust not only permeates the working environment and harms the health of operators if inhaled, but it can also adhere to the transmission components and electrical components of the equipment, affecting its normal operation and service life. Furthermore, some cutting devices lack effective dustproof structures, resulting in a large dust diffusion range, increasing the difficulty of subsequent cleaning, and also negatively impacting the air quality in the work area. Therefore, designing a seamless steel pipe processing cutting device that can effectively collect and treat the dust generated during the cutting process and prevent its diffusion is of significant practical importance.
[0003] During use, the friction between the high-speed rotating saw blade and the steel pipe generates a large amount of metal dust and debris. This dust not only permeates the working environment and harms the health of operators when inhaled, but some cutting devices also lack effective dustproof structures, resulting in a large dust diffusion range, increasing the difficulty of subsequent cleaning, and also adversely affecting the air quality of the working area.

[0006] As a preferred embodiment of the cutting device for processing seamless steel pipes with dustproof function according to the present invention, the sealing component includes a long strip fixedly connected to the inner wall of the first dustproof cover, the surface of the long strip is bonded with elastic cloth, and the elastic cloth is bonded to the inner arc surface of the first dustproof cover.
[0007] In a preferred embodiment of the cutting device for processing seamless steel pipes with dustproof function according to the present invention, both first dustproof covers are V-shaped and the included angles of the two first dustproof covers are opposite.
[0008] As a preferred embodiment of the cutting device for processing seamless steel pipes with dustproof function according to the present invention, the elastic cloth is triangular, and the included angle formed by the elastic cloths on both sides being close to each other is "V" shaped.
[0009] As a preferred embodiment of the cutting device for processing seamless steel pipes with dustproof function of the present invention, the reset component includes a cylinder fixedly connected to the surface of the arc plate, the cylinder being rotatably connected to the second dust cover, and a second torsion spring being sleeved on the surface of the cylinder, the two ends of the second torsion spring being fixedly connected to the second dust cover and the cylinder respectively.
[0010] As a preferred embodiment of the dustproof cutting device for seamless steel pipe processing of the present invention, the power component includes a pressure plate slidably connected to the surface of the cutting machine. The pressure plate is U-shaped, and two inclined blocks are fixedly connected to the inner side of the pressure plate. Two uprights are fixedly connected to the surface of the cutting machine. The pressure plate is slidably connected to the uprights. Springs are fitted on the surfaces of the two uprights. The two ends of the springs are fixedly connected to the cutting machine and the pressure plate, respectively. Elastic ropes are fixedly connected to both sides of the pressure plate. The end of the elastic rope away from the pressure plate is fixedly connected to the back of the arc plate.
[0011] In a preferred embodiment of the cutting device for processing seamless steel pipes with dustproof function according to the present invention, the lower sides of the inclined sides of the two inclined blocks are both located below the first dustproof cover, and the lower side of the first dustproof cover abuts against the inclined surface of the inclined blocks.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By incorporating dustproof components and adjusting the distance between the two first dustproof covers using a positioning assembly, the system can accommodate the cutting of seamless steel pipes of different diameters. When the steel pipe is positioned for cutting, its outer wall contacts the sealing assembly inside the first dustproof cover. The elastic cloth is compressed and deformed to adhere to the surface of the steel pipe, forming a closed space to prevent debris and dust from splashing out. The first dustproof cover blocks debris at the cutting position, while the second dustproof cover expands the protective range to prevent the circular saw from carrying away debris, thus improving the dustproof effect.
[0015] 2. Through the cleaning components, the power unit drives the arc plate to rotate inside the second dust cover. When the arc plate rotates, its inner wall scrapes the debris accumulated inside the second dust cover, pushing the debris towards the center. At the same time, the reset component generates a reverse force after the arc plate rotates, causing the arc plate to return to its initial position for the next cleaning action. This achieves the effect of preventing a large amount of debris from accumulating inside the second dust cover and keeping the inside of the second dust cover clean. It effectively prevents debris accumulation from affecting the rotation of the circular saw, and achieves different effects for the installation or disassembly of steel pipes.
[0016] 3. By striking the component, when the arc plate moves, the arc surface of the guide block can drive the round rod and the abutment plate to move up and down on the inner wall of the arc plate. Then, through the repeated contact between the abutment plate and the triangular block gap, the effect of striking vibration is achieved, which can help the debris on the surface of the arc plate to detach from the connection, thereby improving the cleaning effect.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0020] Example 1 Reference Figure 1 - Figure 6 This is the first embodiment of the present invention. This embodiment provides a cutting device for processing seamless steel pipes with dustproof function, which achieves the effect of preventing dust from splashing at the cutting position of the seamless steel pipe. It includes a dustproof component, including a cutting machine 10. Two first dustproof covers 11 that block the splashing debris at the cutting position are slidably connected to the surface of the cutting machine 10. A second dustproof cover 12 is fixedly connected to the surface of each of the two first dustproof covers 11. An adjustment component 13 for simultaneously adjusting the distance between the two first dustproof covers 11 and the cutting machine 10 is provided. A sealing component 14 for preventing the splashing of debris at the cutting position is provided on the inner side of each of the two first dustproof covers 11.
[0021] Specifically, during the cutting operation, the seamless steel pipe is locked by the locking device on the surface of the cutting machine 10. At the same time, the adjusting component 13 assists the two first dust covers 11 in clamping the steel pipe, and the sealing component 14 is attached to the surface of the steel pipe to achieve a seal. The locking device is existing technology, and its structure and principle will not be described in detail here.
[0022] Furthermore, the positioning assembly 13 includes a central shaft 131 fixedly connected to the side wall of the cutting machine 10. A gear 132 is rotatably connected to the surface of the central shaft 131. A first torsion spring 133 is sleeved on the surface of the central shaft 131. The two ends of the first torsion spring 133 are fixedly connected to the central shaft 131 and the gear 132, respectively. A first toothed plate 134 and a second toothed plate 135 are slidably connected to the side wall of the cutting machine 10. The meshing teeth of the first toothed plate 134 and the second toothed plate 135 mesh with the meshing teeth of the gear 132. The first toothed plate 134 and the second toothed plate 135 are fixedly connected to the sides of the two first dust covers 11, respectively. The sealing assembly 14 includes a strip 141 fixedly connected to the inner wall of the first dust cover 11. An elastic cloth 142 is glued to the surface of the strip 141. The elastic cloth 142 is glued to the inner arc surface of the first dust cover 11.
[0023] When the steel pipe is placed between the two first dust covers 11, it is pressed down individually. At this time, the steel pipe is guided by the short side of the first dust cover 11 to abut against the surface of the lower platform of the cutting machine 10. With the assistance of the first toothed plate 134 and the second toothed plate 135, the two first dust covers 11 can be driven to move away from each other, thereby adjusting the gap position to facilitate the placement of the steel pipe. Subsequently, under the effect of the first torsion spring 133, the first toothed plate 134 and the second toothed plate 135 can be driven by the gear 132 to reset the first dust cover 11 and abut against the surface of the steel pipe. At the same time, the elastic cloth 142 abuts against the arc surface of the steel pipe to achieve a seal. At this time, the sealing operation of the steel pipe cutting position is achieved. When the cutting machine 10 cuts the steel pipe, the debris and dust will not splash to the outside, thus achieving a dustproof effect.
[0024] Preferably, both first dust covers 11 are V-shaped, and the included angles of the two first dust covers 11 are opposite each other. The elastic fabric 142 is triangular, and the included angle formed by the elastic fabrics 142 on both sides being close to each other is V-shaped.
[0025] It should be noted that the "V"-shaped first dust cover 11 can guide the placement of the steel pipe, facilitating its direct placement between the two first dust covers 11. The included angle between the elastic fabrics 142 allows the triangular elastic fabrics 142 to tightly conform to the arc surface of the steel pipe when the outer wall of the steel pipe contacts the elastic fabric 142, forming a ring-shaped sealing area. This design not only accommodates steel pipes of different diameters but also effectively fills the gap between the steel pipe and the inner wall of the first dust cover 11, further enhancing the dustproof effect.
[0026] In use, the seamless steel pipe to be cut is first placed on the cutting platform of the cutting machine 10, and the position of the steel pipe is adjusted so that the cutting part is aligned with the circular saw blade of the cutting machine 10. At this time, the outer wall of the steel pipe will contact the upper short side inclined surface of the two first dust covers 11 arranged in a "V" shape opposite each other. Under the action of the steel pipe's own weight or a slight external force, the steel pipe will press down and push the two first dust covers 11 to separate to both sides. During this process, the first toothed plate 134 and the second toothed plate 135, which are fixedly connected to the side of the first dust cover 11, will slide to both sides synchronously. Since the first toothed plate 134 and the second toothed plate 135 are both meshed with the gear 132, the gear 132 will rotate around the central shaft 131. At the same time, the first torsion spring 133 sleeved on the central shaft 131 is torsionally charged and accumulates elastic potential energy. Once the steel pipe is completely and stably placed, the external force is removed. The first torsion spring 133 releases its elastic potential energy, causing the gear 132 to rotate in the opposite direction. This, in turn, pulls the two first dust covers 11 closer together via the first toothed plate 134 and the second toothed plate 135, until the elastic cloth 142 on the inner wall of the first dust cover 11 is tightly attached to the outer wall of the steel pipe. The elastic cloth 142 is triangular, and the "V"-shaped angle formed by the two elastic cloths 142 approaching each other will undergo adaptive deformation when in contact with the arc surface of the steel pipe, thereby forming an annular sealing area between the steel pipe and the first dust cover 11, effectively preventing debris and dust from splashing from the side during the cutting process. Meanwhile, the "V"-shaped structure of the first dust cover 11 allows its long side to better match the outline of the outer wall of the steel pipe, further enhancing the initial blocking effect. The second dust cover 12 is connected to the surface of the first dust cover 11, extending the protection range outward. At the same time, it covers the surface of the circular saw, which can secondary block the small amount of debris that may escape from the edge of the first dust cover 11, forming double protection and limiting the cutting operation to a relatively enclosed space to the greatest extent.
[0027] In summary, the gear 132 can synchronously drive the first toothed plate 134 and the second toothed plate 135 to achieve position adjustment, and then help the two first dust covers 11 and the elastic cloth 142 to abut against the arc surface of the steel pipe, which can cover the cutting position of the steel pipe with dust and effectively prevent the splashing of debris.
[0028] Example 2 Reference Figure 1 - Figure 7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a cleaning component for a seamless steel pipe processing cutting device with dustproof function, which solves the problem that debris accumulates inside the second dust cover 12 when the circular saw rotates. It includes a cleaning component, including an arc plate 20 rotatably connected to the inside of the second dust cover 12. A reset component 21 for preventing debris accumulation is provided between the arc plate 20 and the second dust cover 12. A power component 22 for adjusting the placement position of the arc plate 20 is provided between the arc plate 20 and the first dust cover 11. The reset component 21 includes a cylinder 211 fixedly connected to the surface of the arc plate 20. The cylinder 211 is rotatably connected to the second dust cover 12. A second torsion spring 212 is sleeved on the surface of the cylinder 211. The two ends of the second torsion spring 212 are fixedly connected to the second dust cover 12 and the cylinder 211, respectively. The power assembly 22 includes a pressure plate 221 slidably connected to the surface of the cutting machine 10. The pressure plate 221 is U-shaped. Two inclined blocks 222 are fixedly connected to the inner side of the pressure plate 221. Two uprights 223 are fixedly connected to the surface of the cutting machine 10. The pressure plate 221 is slidably connected to the uprights 223. Springs 224 are fitted on the surface of the two uprights 223. The two ends of the springs 224 are fixedly connected to the cutting machine 10 and the pressure plate 221, respectively. Elastic ropes 225 are fixedly connected to both sides of the pressure plate 221. The end of the elastic rope 225 away from the pressure plate 221 is fixedly connected to the back of the arc plate 20.
[0029] Specifically, when the steel pipe is placed on the surface of the cutting machine 10, it pushes the two first dust covers 11 away from each other. At this time, the side of the first dust cover 11 will abut against the surface of the inclined block 222. When the first dust cover 11 moves, it will guide the pressure plate 221 to slide downward through the inclined surface of the inclined block 222. Since the elastic rope 225 is normally connected to the arc plate 20 and is in a taut state, when the pressure plate 221 moves down, it will directly pull the arc plate 20 to move and fit against the inner arc surface of the second dust cover 12. Then the steel pipe is placed in the middle of the two first dust covers 11, and the first dust covers 11 can no longer move closer to each other. The first dust cover 11 is placed against the surface of the inclined block 222, and the pressure plate 221 pulls the arc plate 20 tight. Then the operator performs the cutting operation. During the downward movement of the circular saw, it will not contact the arc plate 20 that is attached to the inner arc surface of the second dust cover 12. At the same time, during the cutting process, the debris generated by the circular saw's rotation will accumulate on the surface of the arc plate 20. When the operator removes the steel pipe, the spring 224 will drive the pressure plate 221 to reset. At this time, the arc plate 20 will be released from the limit and will be flipped towards the first dust cover 11 by the effect of the second torsion spring 212, which can push the surface debris towards the center, thereby completing the cleaning operation.
[0030] Furthermore, the lower sides of the inclined sides of both inclined blocks 222 are located below the first dust cover 11, and the lower side of the first dust cover 11 abuts against the inclined surface of the inclined block 222.
[0031] The lower side of the first dust cover 11 abuts against the inclined surface of the inclined block 222. When the upper side of the first dust cover 11 is displaced by the pressure of the steel pipe, it will quickly drive the inclined block 222 and the pressure plate 221 to move, thereby ensuring that the power component 22 can respond in time and drive the arc plate 20 to move.
[0032] In use, when the steel pipe is placed on the platform of the cutting machine 10 and the first dust cover 11 is pushed to move to both sides, the lower edge of the first dust cover 11 will abut against the inclined side of the inclined block 222. As the first dust cover 11 continues to move outward, its lower edge will slide along the inclined surface of the inclined block 222. Since the inclined block 222 is fixedly connected to the pressure plate 221, and the pressure plate 221 is slidably connected to the cutting machine 10 through the upright 223, this sliding process will generate downward pressure on the inclined block 222, causing the pressure plate 221 to overcome the elastic force of the spring 224 and slide vertically downward along the upright 223. As the pressure plate 221 moves downward, the elastic ropes 225 connected to its two sides are pulled down synchronously. The other end of the elastic rope 225 is fixed to the back of the arc plate 20. Therefore, under the pulling action of the elastic rope 225, the arc plate 20, which was originally in its initial position (usually near the first dust cover 11) under the action of the second torsion spring 212, will rotate around the cylinder 211 toward the inner arc surface of the second dust cover 12. During this process, the second torsion spring 212 on the surface of the cylinder 211 will be further twisted and accumulate elastic potential energy. When the movement of the first dust cover 11 reaches its limit position (i.e., the steel pipe is completely placed in place and locked, and the first dust cover 11 stops moving outward), the pressure plate 221 also stops moving downward. At this time, under the continuous pulling force of the elastic rope 225, the inner wall of the arc plate 20 will be tightly attached to the inner arc surface of the second dust cover 12, forming a temporary shield and bearing structure to receive the debris that splashes onto the inner wall of the second dust cover 12 during the cutting process. After the cutting operation is completed, the operator releases the lock on the steel pipe and removes it from the cutting machine 10. Under the restoring force of the first torsion spring 133 in the adjusting assembly 13, the first dust cover 11 will move towards the center. At this time, the pressure of the lower edge of the first dust cover 11 on the inclined block 222 disappears, and the pressure plate 221 slides upward rapidly under the elastic restoring force of the spring 224 on the surface of the upright 223. The elastic rope 225 then relaxes and no longer applies tension to the arc plate 20. At this time, the second torsion spring 212, which has accumulated elastic potential energy, begins to release energy, driving the cylinder 211 to rotate in the opposite direction, thereby causing the arc plate 20 to rotate and reset around the cylinder 211 towards the initial position close to the first dust cover 11. During the resetting and rotation of the arc plate 20, its inner wall effectively scrapes away the debris that accumulated on the inner wall of the second dust cover 12 during the previous bonding process. Since the curvature of the arc plate 20 is adapted to the inner wall of the second dust cover 12, the scraping effect is thorough, and the debris can be continuously pushed to the lower middle position of the second dust cover 12, so that the debris can be concentrated and fall into the collection groove preset on the platform of the cutting machine 10 or fall directly into the external collection device, thereby completing an automatic cleaning of the inner wall of the second dust cover 12.
[0033] In summary, when placing the steel pipe, the wedge block 222 drives the pressure plate 221 to move, and then the elastic rope 225 pulls the arc plate 20, so that the arc plate 20 fits against the inner arc surface of the second dust cover 12, which will not affect the cutting operation of the steel pipe. After the steel pipe is taken out from between the two first dust covers 11, the first dust cover 11 will be reset to the initial position by the effect of the first torsion spring 133, and the arc plate 20 will be reset and rotated by the effect of the second torsion spring 212 after being released from the limit, thereby helping to push the debris accumulated on the surface towards the center, thereby achieving the cleaning effect.
[0034] Example 3 Reference Figure 1 - Figure 8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a striking component of a cutting device for seamless steel pipe processing with dustproof function, which solves the problem that some debris is tightly attached and difficult to clean. It includes a striking component, which includes several triangular blocks 30 fixedly connected to the inner wall of the arc plate 20. A round rod 31 is slidably connected to the inner wall of the arc plate 20. Two abutment plates 32 are fixedly connected to the surface of the round rod 31. A guide component 33 is provided between the round rod 31 and the second dust cover 12 to assist in adjusting the position of the round rod 31. The guide component 33 includes a guide hole 331 opened on the surface of the second dust cover 12. Six guide blocks 332 are fixedly connected to the inner wall of the guide hole 331. The six guide blocks 332 are all semi-circular blocks. The arc surface of the round rod 31 abuts against the arc surface of the guide block 332.
[0035] Specifically, when the arc plate 20 moves toward the second dust cover 12, the round rod 31 inside the guide hole 331 moves along the arc surface of the guide block 332 and drives the round rod 31 inside the arc plate 20 to move up and down, thereby driving the short side of the abutment plate 32 to repeatedly contact the gap position of multiple triangular blocks 30. By tapping, a vibration effect can be generated, which can help clean the debris attached to the surface of the arc plate 20 to the accumulation position.
[0036] Furthermore, the two abutment plates 32 are L-shaped, and the short sides of both abutment plates 32 are semi-circular.
[0037] The short side of the abutment plate 32 is semi-circular, which can reduce the contact area when it comes into contact with the inclined surface of the triangular block 30, thereby improving the smoothness of the abutment plate 32 when it moves between multiple triangular blocks 30.
[0038] In use, when the arc plate 20 rotates around the cylinder 211 towards the inner arc surface of the second dust cover 12 under the pull of the elastic rope 225, the round rod 31 slidably connected to its inner wall moves accordingly. Because the arc surface of the round rod 31 abuts against the arc surface of the six semi-circular guide blocks 332 fixedly distributed within the guide hole 331, the rotation of the arc plate 20 causes the round rod 31 to slide up and down with the height change of the guide blocks 332. The round rod 31 slides down as it moves from the high point to the low point of the guide block 332, and vice versa. This sliding is transmitted to the two "L"-shaped abutment plates 32 fixedly connected to the round rod 31, causing the short side (semi-circular) of the abutment plate 32 to reciprocate between the pre-set fixed arrangement of triangular blocks 30 on the inner wall of the arc plate 20. The inclined side of the triangular block 30 engages with the semi-circular edge of the short side of the abutment plate 32. When the short side of the abutment plate 32 moves up and down, it collides with the inclined surface of the triangular block 30, causing the arc plate 20 to vibrate slightly. The vibration is transmitted to the surface of the arc plate 20, which can loosen the attached dust-like debris. Subsequently, when the arc plate 20 is flipped towards the first dust cover 11 under the action of the restoring force of the second torsion spring 212, the loosened debris falls off the surface of the arc plate 20 under its own weight and the flipping thrust of the arc plate 20 and gathers in the middle to avoid residue.
[0039] In summary, when the elastic rope 225 pulls the arc plate 20, the round rod 31 will move along the arc surface of the guide block 332. At this time, the round rod 31 and the abutment plate 32 can move up and down on the inner wall of the arc plate 20. The repeated contact between the abutment plate 32 and the triangular block 30 will produce a vibration effect, which can ensure that dust will not accumulate on the surface of the arc plate 20 during the process of attaching to the second dust cover 12.
