Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rotary cutting equipment, in particular to automatic rotary cutting equipment for stainless steel pipe machining and a process. BACKGROUND

[0002] The stainless steel pipe is a pipeline made of stainless steel material and can be divided into austenitic stainless steel pipe, ferritic stainless steel pipe, martensitic stainless steel pipe and duplex stainless steel pipe, etc. The automatic rotary cutting equipment for stainless steel pipe machining is an automatic machining equipment designed for the efficient and accurate cutting requirement of the stainless steel pipe, integrates full-process automatic functions such as feeding, positioning, cutting and unloading, has the advantages of high automation degree, good cutting quality and high production efficiency, and is widely applied to batch production scenes of the stainless steel pipe. In the process of automatic rotary cutting of the pipe, the pipe is prone to vibration in the instant of contact with the high-speed rotating cutter, so that the pipe is prone to deviation under the contact pressure, and the cutting path of the pipe is deviated. Meanwhile, in the automatic cutting, the steel pipe surface is smooth, so that deviation is prone to occur in the transmission process. SUMMARY

[0003] To solve the above technical problems, the application is implemented by the following technical scheme: an automatic rotary cutting equipment for stainless steel pipe machining, comprising: a frame body, a rotary cutting mechanism being installed on the top of the frame body; a positioning mechanism and a guide conveying mechanism, the positioning mechanism being installed on one side of the top of the frame body away from the rotary cutting mechanism, and the guide conveying mechanism being installed in the interior of the positioning mechanism; wherein the rotary cutting mechanism comprises a fixed frame, a clamping assembly being fixedly installed on the inner wall of the fixed frame, and a guide chute being fixedly installed on the side of the fixed frame away from the positioning mechanism; The locking assembly includes a sliding plate with rectangular grooves on its opposite sides. A third cylinder is fixedly mounted on both the upper and lower sides of the sliding plate. A fixing plate is slidably mounted at the rectangular grooves of the sliding plate. The non-opposing side of the fixing plate is fixedly connected to the output end of the third cylinder. An arc-groove frame is fixedly mounted on the opposite side of the fixing plate. An arc-shaped through groove is formed at the top of the arc-groove frame. Through the arc-shaped through groove of the arc-groove frame, in conjunction with the inner sliding plate and the rubber plate, the friction between the rubber plate and the pipe during locking is utilized to prevent the pipe from sliding during the cutting process. The pressure is transferred to the inner slide plate, causing it to compress the side pads within the arc-shaped groove, resulting in a sliding tendency. This causes one end of the inner slide plates to move closer together, increasing the clamping pressure on the pipe and restricting its movement. This prevents the pipe from slipping due to vibrations caused by cutting friction during the cutting process, which could lead to a deviation in the cutting path. The inner slide plate is slidably installed in the arc-shaped groove of the arc-shaped frame, and a side pad is engaged between the inner slide plate and the arc-shaped frame. The side pads are made of rubber, and rubber plates are fixedly installed on the opposite sides of the inner slide plate.

[0004] Preferably, the side pads are symmetrically installed along the center of the arc groove frame. Side clamps are fixedly installed on both sides of the opposite face of the fixing plate. The opposite face of the side clamps is a centrally concave arc surface, and the arc surface of the side clamps is uniformly provided with arc-shaped protrusions. These protrusions on the side clamps contact the pipe, reducing the contact area. During cutting, airflow gaps exist between the arc-shaped protrusions, ensuring that heat from the surface of the pipe near the cutting position can be transferred to the air for heat dissipation during the cutting process, while simultaneously reducing the contact area with the pipe and minimizing heat loss. Friction is used to prevent scratches on the pipe surface during cutting vibration. A side groove plate is fixedly installed on the side of the fixed frame away from the positioning mechanism. The side groove plates are symmetrically installed along the center of the axis of the fixed frame, and each side groove plate has a groove on its outer side. A second cylinder is fixedly installed on the top of the side groove plate. A rectangular groove frame is slidably installed between the side groove plates. The two ends of the rectangular groove frame are fixedly connected to the output end of the second cylinder. A saw blade is rotatably installed on the inner wall of the rectangular groove frame. A second motor is fixedly installed on the outer side of the rectangular groove frame, and the output end of the second motor is fixedly connected to the saw blade.

[0005] Preferably, the positioning mechanism includes a support frame. Fixing strips are fixedly installed on both sides of the inner wall of the support frame. Inner arc plates are fixedly installed on the opposite surfaces of the fixing strips. A first cylinder is fixedly installed on the top of the outer side of the inner arc plate. The output end of the first cylinder passes through the inner arc plate and extends to its other side. The first cylinder is symmetrically installed along the center of the axis of the inner arc plate, and an arc clamping plate is fixedly installed at the output end of the first cylinder. The opposite surfaces of the arc clamping plates are arc surfaces, and inclined pressure strips are fixedly installed on the opposite surfaces of the arc clamping plates. The end of the inclined pressure strip away from the arc clamping plate is inclined downwards, and a rotating groove is evenly formed at the end of the inclined pressure strip away from the arc clamping plate. A top block is rotatably installed at each of the rotating grooves of the inclined pressure strip. The top block cooperates with the clamping strip, and by rotating, it cooperates with the arc surface of the clamping strip to position and clamp the pipe, thereby reducing [damage / loss]. The contact area with the pipe is reduced to decrease the friction on the pipe and prevent the pipe from being obstructed during transmission due to high frictional resistance. Clamping strips are fixedly installed on the opposite surfaces of the arc clamping plates. These clamping strips are located below the inclined pressure strips, and clamping strips are slidably installed on the outer sides of the clamping strips. Through the cooperation of the clamping strips and the gaskets, during the positioning of the inserted pipe, the clamping strips contact both sides of the pipe before the top block. Under clamping pressure, the gaskets deform, clamping the pipe with equal pressure on both sides, keeping the pipe in a centered position and preventing pipe displacement. Simultaneously, the arc surface of the clamping strip contacts the pipe and cooperates with the arc surface of the pipe, reducing the contact area and preventing scratches on the pipe surface. Gaskets made of elastic material are fixedly installed between the clamping strips and the clamping strips, and the opposite surfaces of the clamping strips are all arc surfaces with a central convex position.

[0006] Preferably, the guiding mechanism includes a support plate, with both sides of the support plate fixedly connected to the opposite surfaces of the inner arc plate. A shaft groove is fixedly installed at the center of the top of the support plate. Wheel grooves are formed at both ends of the shaft groove, and shaft grooves are evenly formed at the top of the shaft groove. A rotating wheel is rotatably installed at each shaft groove of the shaft groove, and a locking block is fixedly installed at the top of the shaft groove. The rotating wheel is rotatably installed at the shaft groove of the shaft groove via the locking block. A first motor is fixedly installed at both ends of the outer side of the shaft groove, and a rotating shaft is rotatably installed at each wheel groove of the shaft groove. One end of the rotating shaft is fixedly connected to the output end of the first motor, and the outer side of the rotating shaft is fixedly connected to the first motor. A feed wheel is fixedly installed. Through the feed wheel's cooperation with an inner gasket ring and a rubber ring gasket, during the positioning process, the inner gasket ring and the rubber ring gasket deform under pressure, causing the inner grooved ring to shift inside the feed wheel. This allows the rubber ring gasket to deform and adhere to the pipe surface, increasing the contact area, while simultaneously allowing the pipe to penetrate deeper into the feed wheel. The groove of the feed wheel cooperates with the positioning mechanism to prevent pipe deviation during transmission. An inner gasket ring is fixedly installed on the inner wall of the feed wheel, and an inner grooved ring is fixedly installed on the outer side of the inner gasket ring. The outer side of the inner grooved ring has a groove, and a rubber ring gasket is fixedly installed at the groove. The outer side of the inner grooved ring does not contact the inner wall of the feed wheel.

[0007] An automated rotary cutting process for stainless steel pipe processing consists of the following steps: S1. Pipe positioning: Place the stainless steel pipe to be automatically cut into the equipment, and clamp and press the pipe through the positioning mechanism to place the stainless steel pipe in the center of the equipment. S2. Pipe conveying: The positioning mechanism and the guiding mechanism work together to use the clamping and positioning pressure of the positioning mechanism on the stainless steel pipe to make the bottom of the pipe fit tightly with the guiding mechanism, increase the contact pressure and improve the friction. During processing, the guiding mechanism drives the stainless steel pipe to move. S3. Pipe clamping: After the stainless steel pipe enters the rotary cutting position under the drive of the guiding mechanism, the outer pipe is clamped by the clamping component near the rotary cutting position to restrict the movement of the pipe and limit the movement of the pipe during rotary cutting. S4. Pipe rotary cutting: After the pipe is sent to the cutting position, it is clamped and fixed by the clamping component. Then, the pipe is rotary cut by the cutter in the rotary cutting mechanism during the movement.

[0008] This invention provides an automated rotary cutting device for processing stainless steel pipes. It has the following advantages: (i) The automated rotary cutting equipment for stainless steel pipe processing uses the arc-shaped through groove of the arc groove frame in conjunction with the inner slide plate and the rubber plate. When the pipe is clamped, the friction between the rubber plate and the pipe causes the pipe to slide during the cutting process. This tendency is transmitted to the inner slide plate, causing the inner slide plate to compress the side pad deformation within the arc-shaped through groove, resulting in a sliding tendency. This causes one end of the inner slide plates to move closer together, increasing the clamping pressure on the pipe and restricting the movement of the pipe. This prevents the pipe from sliding due to vibrations caused by cutting friction during the cutting process, which would lead to deviation of the cutting path.

[0009] (ii) The automated rotary cutting equipment for stainless steel pipe processing contacts the pipe through the arc-shaped protrusions on the side clamping plate, reducing the contact area with the pipe. During the cutting process, there are air flow gaps between the arc-shaped protrusions, ensuring that the heat of the surface of the pipe near the cutting position can be transferred to the air for heat dissipation during the cutting and heating process. At the same time, the contact area with the pipe is reduced, friction is reduced, and scratches on the surface of the pipe are avoided during the cutting vibration.

[0010] (III) The automated rotary cutting equipment for stainless steel pipe processing uses a top block and a clamping bar to cooperate. The top block is rotated and installed, and the clamping bar is coordinated with the arc surface. While positioning and clamping the pipe, the contact area between the top block and the pipe is reduced, the friction force on the pipe is reduced, and the pipe transmission is prevented from being obstructed due to high frictional resistance during the pipe transmission process.

[0011] (iv) The automated rotary cutting equipment for stainless steel pipe processing uses a clamping bar and a washer ring to position the inserted pipe. During the positioning process, the clamping bar contacts both sides of the pipe before the top block. Under clamping pressure, the washer ring changes shape and clamps the pipe with the same pressure on both sides, keeping the pipe in the center position and preventing the pipe from shifting. At the same time, the arc surface of the clamping bar contacts the pipe and matches the arc surface of the pipe surface to reduce the contact area and prevent scratching the pipe surface.

[0012] (v) The automated rotary cutting equipment for stainless steel pipe processing uses a feed wheel in conjunction with an inner pad and a rubber ring pad. During the positioning process, the inner pad and the rubber ring pad deform under pressure, causing the inner groove ring to shift inside the feed wheel. This causes the rubber ring pad to deform and adhere to the surface of the pipe, increasing the contact area, while simultaneously allowing the pipe to penetrate deeper into the feed wheel. The groove of the feed wheel cooperates with the positioning mechanism to prevent the pipe from shifting during transmission. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] For the first embodiment, please refer to... Figures 1 to 2 andFigures 10 to 12 The present invention provides a technical solution: An automated rotary cutting device for processing stainless steel pipes includes: The frame 1 has a rotary cutting mechanism 4 installed on its top. Positioning mechanism 2 and guiding mechanism 3 are installed on the top of frame 1 on the side away from rotary cutting mechanism 4, and guiding mechanism 3 is installed inside positioning mechanism 2. The rotary cutting mechanism 4 includes a fixed frame 41, a clamping component 48 is fixedly installed on the inner wall of the fixed frame 41, and a guide groove 47 is fixedly installed on the side of the fixed frame 41 away from the positioning mechanism 2. The clamping assembly 48 includes a sliding plate 481, with rectangular grooves on opposite sides. A third cylinder 482 is fixedly mounted on both the upper and lower sides of the sliding plate 481. A fixing plate 483 is slidably mounted on the rectangular grooves of the sliding plate 481. In the clamping assembly 48, when the pipe is conveyed to the cutting position by the guiding mechanism 3, the third cylinder 482 is activated, causing the fixing plates 483 to move closer together. During this approach, the rubber plate 485 first contacts the surface of the pipe, and under the action of the third cylinder 482, the contact pressure gradually increases, causing the rubber plate 485 to deform and adhere to the surface of the pipe. Subsequently, the side clamps 484 on both sides contact the pipe, utilizing the arc-shaped protrusions of the side clamps 484 to complete the clamping of the pipe. The non-opposing surfaces of the fixing plates 483 are fixed to the output ends of the third cylinders 482. The connection is made of a fixed plate 483 with an arc groove frame 488 fixedly installed on the opposite side. The top of the arc groove frame 488 has an arc-shaped through groove, and an inner slide plate 486 is slidably installed in the arc-shaped through groove of the arc groove frame 488. A side pad plate 487 is engaged between the inner slide plate 486 and the arc groove frame 488. During the cutting process, when the pipe tends to slide due to the cutting vibration, the arc groove of the arc groove frame 488, in conjunction with the friction between the rubber plate 485 and the pipe, transmits the tendency to the inner slide plate 486, causing the inner slide plate 486 to slide in the arc groove. After the tendency appears, the inner slide plate 486 compresses the side pad plate 487 and one end tends to move closer to each other, increasing the clamping force on the pipe and restricting the movement of the pipe. The side pad plate 487 is made of rubber material, and the opposite side of the inner slide plate 486 is fixedly installed with a rubber plate 485.

[0017] Side pads 487 are symmetrically installed along the center of the arc groove frame 488. Side clamps 484 are fixedly installed on both sides of the opposite face of the fixing plate 483. The opposite face of the side clamps 484 is a centrally concave arc surface, and the arc surface of the side clamps 484 is evenly provided with arc-shaped protrusions. A side groove plate 42 is fixedly installed on the side of the fixing frame 41 away from the positioning mechanism 2. The side groove plates 42 are symmetrically installed along the center of the axis of the fixing frame 41, and grooves are opened on the outer side of the side groove plates 42. A second cylinder 45 is fixedly installed on the top of the side groove plate 42. When the cutting position of the pipe corresponds to the position of the saw blade 46, the feeding of the pipe is stopped, and then... The pipe is clamped and fixed near the cutting position on the surface of the pipe by the clamping component 48, thus restricting the pipe. Then, the second cylinder 45 and the second motor 44 cooperate to make the second motor 44 drive the saw disc 46 to rotate. At the same time, the second cylinder 45 drives the rectangular groove frame 43 to move down between the side groove plates 42, so that the saw disc 46 performs rotary cutting on the pipe. The rectangular groove frame 43 is slidably installed between the side groove plates 42. The two ends of the rectangular groove frame 43 are fixedly connected to the output end of the second cylinder 45. The saw disc 46 is rotatably installed on the inner wall of the rectangular groove frame 43. The second motor 44 is fixedly installed on the outer side of the rectangular groove frame 43. The output end of the second motor 44 is fixedly connected to the saw disc 46.

[0018] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 6As shown, the positioning mechanism 2 includes a support frame 201. Fixing strips 202 are fixedly installed on both sides of the inner wall of the support frame 201. Inner arc plates 203 are fixedly installed on opposite sides of the fixing strips 202. A first cylinder 204 is fixedly installed on the top of the outer side of the inner arc plate 203. The output end of the first cylinder 204 passes through the inner arc plate 203 and extends to the other side. The first cylinder 204 is symmetrically installed along the center of the axis of the inner arc plate 203, and an arc clamping plate 20 is fixedly installed on the output end of the first cylinder 204. 5. Position the pipe directly above the guiding mechanism 3 and between the arc clamping plates 205. Then, activate the first cylinder 204, causing it to move the arc clamping plates 205 closer together. During this movement, the inclined pressure strips 206 move the top block 207 closer to the pipe. Before the top block 207 approaches the pipe, the clamping strips 210 first contact both sides of the pipe. The opposing surfaces of the arc clamping plates 205 are arc surfaces, and inclined pressure strips 206 are fixedly installed on the opposing surfaces of the arc clamping plates 205. The end of the inclined pressure strip 206 away from the arc clamping plate 205 is inclined downwards, and the end of the inclined pressure strip 206 away from the arc clamping plate 205 is evenly provided with rotating grooves. A top block 207 is rotatably installed at each rotating groove of the inclined pressure strip 206. A snap-fit ​​strip 208 is fixedly installed on the opposite side of the arc clamping plate 205. The snap-fit ​​strip 208 is located below the inclined pressure strip 206. After contact, through the continuously increasing contact pressure, the clamping strip 210 slides and compresses the compression pad ring 209 on the outside of the snap-fit ​​strip 208 until the top block 207 contacts. On both sides of the top of the pipe, pressure is applied diagonally downwards to increase the contact pressure between the bottom of the pipe and the guide mechanism 3. At the same time, the pressure applied to the pipe by the top block 207 and the clamping strip 210 keeps the pipe in the center position, completing the positioning of the pipe's transmission path. The clamping strip 210 is slidably installed on the outer side of the clamping strip 208. A washer 209 is fixedly installed between the clamping strip 210 and the clamping strip 208. The washer 209 is made of elastic material, and the opposite surfaces of the clamping strip 210 are both arc surfaces with a raised center position.

[0019] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9 and Figure 13As shown, the guiding mechanism 3 includes a support plate 301. Both sides of the support plate 301 are fixedly connected to the opposite surfaces of the inner arc plate 203. A shaft groove strip 302 is fixedly installed at the center of the top of the support plate 301. Wheel grooves are provided at both ends of the shaft groove strip 302, and shaft grooves are evenly provided at the top of the shaft groove strip 302. Rotary wheels 303 are rotatably installed at the shaft grooves of the shaft groove strip 302. A locking block 305 is fixedly installed at the top of the shaft groove strip 302. The positioning mechanism 2 restricts the positioning of the pipe, allowing the pipe to... The pipe is positioned at the center of the equipment. When the pipe is first inserted, its bottom contacts the rubber rings 308 at both ends. As the positioning mechanism 2 applies pressure to position the pipe, it experiences downward pressure, causing the pipe to compress the rubber rings 308. This causes the rubber rings 308 to engage with the inner ring 310, deforming under pressure. This causes the inner groove ring 309 to move within the transfer wheel 307 until the pipe contacts the rotating wheel 303. The rotating wheel 303 then supports the pipe, restricting its downward movement. This, in conjunction with the positioning mechanism 2, positions the pipe... For positioning, the rotating wheel 303 is rotatably mounted on the shaft groove of the shaft groove strip 302 via the locking block 305. A first motor 306 is fixedly mounted at both ends of the outer side of the shaft groove strip 302. A rotating shaft 304 is rotatably mounted on the wheel groove of the shaft groove strip 302. One end of the rotating shaft 304 is fixedly connected to the output end of the first motor 306. A conveying wheel 307 is fixedly mounted on the outer side of the rotating shaft 304. An inner washer ring 310 is fixedly mounted on the inner wall of the conveying wheel 307. When conveying the pipe, the first motor 306 is started, causing the first motor 306 to... A motor 306 drives the material transfer wheel 307 to rotate via a rotating shaft 304. The material transfer wheel 307 drives the rubber ring pad 308 through the inner gasket ring 310 and the inner groove ring 309. The friction between the pipe and the rubber ring pad 308 drives the pipe to move. The inner groove ring 309 is fixedly installed on the outer side of the inner gasket ring 310. The outer side of the inner groove ring 309 has a groove, and the rubber ring pad 308 is fixedly installed in the groove of the inner groove ring 309. The outer side of the inner groove ring 309 does not contact the inner wall of the material transfer wheel 307.

[0020] An automated rotary cutting process for stainless steel pipe processing consists of the following steps: S1. Pipe positioning: Place the stainless steel pipe to be automatically cut into the equipment, and clamp and press the pipe through the positioning mechanism 2 to make the stainless steel pipe in the center of the equipment. S2. Pipe conveying: The positioning mechanism 2 and the guiding mechanism 3 work together to use the clamping and positioning pressure of the positioning mechanism 2 on the stainless steel pipe to make the bottom of the pipe fit tightly with the guiding mechanism 3, increase the contact pressure and improve the friction. During processing, the guiding mechanism 3 drives the stainless steel pipe to move. S3. Pipe clamping: After the stainless steel pipe enters the rotary cutting position under the drive of the guide mechanism 3, the outer pipe is clamped by the clamping component 48 near the rotary cutting position to restrict the movement of the pipe and limit the movement of the pipe during rotary cutting. S4. Pipe rotary cutting: After the pipe is sent to the cutting position, it is clamped and fixed by the clamping component 48. Then, the pipe is rotary cut by the cutter in the rotary cutting mechanism 4 during the movement.

[0021] In use, the worker inserts the pipe to be automatically cut into the equipment from one side of the positioning mechanism 2, so that the pipe is in the center of the equipment under the clamping pressure of the positioning mechanism 2. At the same time, the pressure of the positioning mechanism 2 on the pipe makes the bottom of the pipe fit tightly against the guide mechanism 3. Then, the guide mechanism 3 drives the pipe to move, so that one end of the pipe enters the interior of the cutting mechanism 4. After the pipe cutting position corresponds with the blade of the cutting mechanism 4, the pipe is fixed by the clamping component 48. Then, the blade performs the cutting process on the pipe.

[0022] When the pipe is inserted, it is positioned directly above the guide mechanism 3 and between the arc clamps 205. Then, the first cylinder 204 is activated, causing the arc clamps 205 to move closer together. During the movement, the inclined pressure bar 206 drives the top block 207, bringing the top block 207 closer to the pipe. Before the top block 207 approaches the pipe, the clamping bar 210 first contacts both sides of the pipe. After contact, through continuously increasing contact pressure, the clamping bar 210 slides and compresses the compression pad ring 209 on the outside of the clamping bar 208 until the top block 207 contacts both sides of the top of the pipe, applying downward pressure to the pipe. This increases the contact pressure between the bottom of the pipe and the guide mechanism 3. Simultaneously, the pressure applied to the pipe by the top block 207 and the clamping bar 210 positions the pipe in the center, completing the pipe's transmission path positioning.

[0023] In the guiding mechanism 3, the positioning mechanism 2 restricts the positioning of the pipe, ensuring that the pipe is in the center of the equipment. When the pipe is first inserted, its bottom contacts the rubber ring pads 308 at both ends. When the positioning mechanism 2 applies pressure to position the pipe, the pipe is subjected to downward pressure, causing the pipe to press against the rubber ring pads 308. This causes the rubber ring pads 308 to engage with the inner pad ring 310 and deform under pressure, causing the inner groove ring 309 to move inside the conveyor wheel 307 until the pipe contacts the rotating wheel 303. The rotating wheel 303 then supports the pipe and restricts its downward movement, thus positioning the pipe in conjunction with the positioning mechanism 2. When conveying the pipe, the first motor 306 is started, causing the first motor 306 to drive the conveyor wheel 307 to rotate via the rotating shaft 304. The conveyor wheel 307 then drives the rubber ring pads 308 via the inner pad ring 310 and the inner groove ring 309, using the friction between the pipe and the rubber ring pads 308 to move the pipe.

[0024] In the rotary cutting mechanism 4, when the cutting position of the pipe corresponds to the position of the saw disc 46, the feeding of the pipe is stopped. Then, the clamping component 48 clamps and fixes the pipe surface near the cutting position to restrict the pipe. Then, the second cylinder 45 cooperates with the second motor 44 to make the second motor 44 drive the saw disc 46 to rotate. At the same time, the second cylinder 45 drives the rectangular groove frame 43 to move down between the side groove plates 42, so that the saw disc 46 performs rotary cutting on the pipe.

[0025] In the clamping assembly 48, after the pipe is conveyed to the cutting position by the guiding mechanism 3, the third cylinder 482 is activated, causing the fixing plates 483 to move closer together. During the approach process, the rubber plate 485 first contacts the surface of the pipe, and under the action of the third cylinder 482, the contact pressure gradually increases, causing the rubber plate 485 to deform and adhere to the surface of the pipe. Subsequently, the side clamps 484 on both sides contact the pipe, and the arc-shaped protrusions of the side clamps 484 contact the pipe to complete the clamping of the pipe. During the cutting process, when the pipe tends to slide due to the cutting vibration, the arc groove of the arc groove frame 488, in conjunction with the friction between the rubber plate 485 and the pipe, transmits the tendency to the inner sliding plate 486, causing the inner sliding plate 486 to slide within the arc groove. After the tendency appears, the inner sliding plate 486 compresses the side pad 487 and one end tends to move closer together, increasing the clamping force on the pipe and restricting the movement of the pipe.
