That is to say, the device can realize the feeding of the pipe to be processed and the beveling processing.

[0019] Furthermore, since the cutter head can move radially along the movable ring, the feed rate can be adjusted by moving the cutter head to accommodate pipes of different diameters.

This ensures that the pipe conveying mechanism keeps the axial position of pipes of different diameters unchanged when conveying them, allowing the beveling mechanism to be suitable for processing pipes of different diameters without changing its own position.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] refer to Figures 1 to 8 This application provides an automatic pipe welding bevel preparation device, including: a platform 100 and a bevel processing mechanism 200 and a pipe conveying mechanism 300 disposed on the platform 100.

[0038] The beveling mechanism 200 includes a fixed ring 201 and a movable ring 202. The fixed ring 201 is provided with a fixing component for coaxially fixing the fixed ring 201 to the pipe 1 to be processed. The movable ring 202 is coaxially and rotatably connected to the fixed ring 201. The movable ring 202 is provided with a cutting component, which includes a cutter head 203. The cutter head 203 is used to cut the pipe 1 to be processed to form a bevel when the movable ring 202 rotates relative to the fixed ring 201. The cutter head 203 can move radially along the movable ring 202 to adjust the feed rate of the cutter head 203.

[0039] The pipeline conveying mechanism 300 includes a chute 301, multiple sliding wheels 302, and multiple drive wheels 303. The chute 301 is disposed on the platform 100, and the axial direction of the chute 301 is aligned with the axial direction of the fixed ring 201. The sliding wheels 302 are respectively disposed on both sides of the inner wall of the chute 301 and are used to support the pipeline 1 to be processed. The drive wheels 303 are disposed on the platform 100 and are used to rotate to drive the pipeline 1 to be processed to move axially within the chute 301. The drive wheels 303 and the sliding wheels 302 form a support trajectory, and both the drive wheels 303 and the sliding wheels 302 can move radially along the fixed ring 201 to adjust the support trajectory.

[0040] The automatic pipe welding beveling preparation device according to this application includes a beveling processing mechanism 200 and a pipe conveying mechanism 300. The pipe conveying mechanism 300 can transport the pipe 1 to be processed to the processing position, and the beveling processing mechanism 200 can process the pipe 1 to be processed to form a bevel. That is to say, the device can realize the loading and unloading of the pipe 1 to be processed and the beveling processing.

[0041] Furthermore, since the cutter head 203 can move radially along the movable ring 202, the feed rate of the cutter head 203 can be adjusted by moving the cutter head 203 to suit the machining of pipes with different diameters. Since both the drive wheel 303 and the sliding wheel 302 can move radially along the fixed ring 201, the support trajectory can be adjusted by moving the drive wheel 303 and the sliding wheel 302, so that the pipe conveying mechanism 300 can keep the axial position of pipes with different diameters unchanged when conveying them. This allows the beveling mechanism 200 to be suitable for machining pipes with different diameters without changing its own position.

[0042] In some examples, both the fixed ring 201 and the movable ring 202 are circular rings, with the fixed ring 201 fitted over the movable ring 202. This limits the radial displacement of the movable ring 202 during rotation, ensuring the cutting effect. The embodiments in this application do not specifically limit this aspect.

[0043] In some examples, the fixed ring 201 is provided with a rotating gear 204 and a rotating motor 205. The rotating gear 204 passes through the fixed ring 201, and the rotating motor 205 is connected to the rotating gear 204 and is used to drive the rotating gear 204 to rotate circumferentially. The outer surface of the movable ring 202 is provided with gear teeth 206, which mesh with the rotating gear 204. In use, the rotating motor 205 can drive the rotating gear 204 to rotate circumferentially, thereby driving the movable ring 202 to rotate circumferentially relative to the fixed ring 201. This enables the movable ring 202 to rotate relative to the fixed ring 201, thereby driving the cutter head 203 to cut the pipe 1 to be processed to form a bevel. The embodiments of this application do not specifically limit this aspect.

[0044] In some examples, the fixing assembly includes multiple radial push rods 207, which are disposed on the end face of the fixing ring 201 and spaced apart circumferentially along the fixing ring 201. The radial push rods 207 are configured to extend and retract radially along the fixing ring 201 to clamp and fix the pipe 1 to be processed. In specific configurations, the radial push rods 207 can be pneumatic push rods, electric push rods, etc., and can extend and retract their telescopic rods radially along the fixing ring 201, thereby clamping or releasing the pipe 1 to be processed. This application does not specifically limit the specific implementation of these embodiments.

[0045] In some examples, the fixing assembly also includes multiple arc-shaped clamps 208, which are respectively disposed on multiple radial push rods 207. Specifically, each arc-shaped clamp 208 is disposed at the front end of the telescopic rod of the corresponding radial push rod 207. When the radial push rod 207 extends or retracts its telescopic rod along the radial direction of the fixing ring 201, the pipe 1 to be processed can be clamped by the arc-shaped clamps 208, which increases the contact area and thus helps to improve the fixing effect. This application does not specifically limit the embodiments in this regard.

[0046] In some examples, the cutting assembly also includes a moving unit on which the cutter head 203 is mounted. When the moving unit is activated, it drives the cutter head 203 to move radially along the movable ring 202. Specifically, the moving unit includes a fixed frame 209, a lead screw 210, a slider 211, and a first motor 212. The fixed frame 209 is a rectangular frame and is disposed on the end face of the movable ring 202. The lead screw 210 is rotatably mounted on the fixed frame 209 and extends radially along the movable ring 202. The slider 211 is slidably mounted on the fixed frame 209 and threadedly engaged with the lead screw 210; the cutter head 203 is disposed on the slider 211. The first motor 212 is mounted on the fixed frame 209 and connected to the lead screw 210. In use, the first motor 212 can drive the lead screw 210 to rotate circumferentially. When the lead screw 210 rotates circumferentially, it drives the slider 211 to move along the axial direction of the lead screw 210, thereby driving the cutter head 203 to move along the axial direction of the lead screw 210 (or the radial direction of the movable ring 202). This embodiment of the application does not specifically limit this.

[0047] In some examples, the cutting assembly also includes a rotating unit mounted on the slider 211. The cutter head 203 is mounted on the rotating unit, indirectly mounted on the slider 211. When the rotating unit is activated, it drives the cutter head 203 to rotate relative to the movable ring 202, thereby adjusting the angle of the cutter head 203 to cut bevels of different angles on pipes. Specifically, the rotating unit includes a mounting bracket 213, a rotating shaft, and a second motor 214. The mounting bracket 213 has a U-shaped structure and is mounted on the slider 211. The rotating shaft is rotatably mounted on the mounting bracket 213, and the cutter head 203 is mounted on the rotating shaft. The second motor 214 is mounted on the mounting bracket 213 and connected to the rotating shaft. In use, the second motor 214 can drive the rotating shaft to rotate circumferentially, and the rotation of the rotating shaft can drive the cutter head 203 to rotate relative to the movable ring 202. This embodiment of the application does not specifically limit the specific implementation of the rotating unit.

[0048] In some examples, the beveling mechanism 200 is disposed within and fixedly connected to the chute 301. This arrangement allows the pipe 1 to be beveled without having to be removed from the chute 301, which reduces the moving distance of the pipe 1 and speeds up the processing compared to the method of removing the pipe 1 from the chute 301 before processing.

[0049] In some examples, the retaining ring 201 is provided with mounting components, and the retaining ring 201 is mounted to the slide groove 301 via the mounting components. Specifically, mounting components are respectively provided on opposite radial sides of the retaining ring 201, and the mounting components include a mounting base 215 and a screw 216 disposed on the mounting base 215. In specific installation, the mounting base 215 is placed on the upper edge of the slide groove 301, and the screw 216 is screwed into the slide groove 301 to fix the retaining ring 201 to the slide groove 301, thereby fixing the beveling mechanism 200 to the slide groove 301. This embodiment of the application does not specifically limit the specific implementation of this method.

[0050] In some examples, the retaining ring 201 is axially movable along the slide groove 301 to move it to the mounting position. Specifically, the mounting base 215 is equipped with rollers 217 located between the mounting base 215 and the slide groove 301 to facilitate the movement of the retaining ring 201. Furthermore, to prevent the screw 216 from contacting the slide groove 301 and causing friction during movement, a limiting unit can be provided between the screw 216 and the mounting base 215 to prevent the screw 216 from approaching the slide groove 301 on its own. For example, the limiting unit includes a limiting frame 218, a support plate 219, and a spring 220. The limiting frame 218 is sleeved on the outside of the screw 216 and installed on the upper surface of the mounting base 215, forming a limiting space between the limiting frame 218 and the mounting base 215. The support plate 219 is located within the limiting space and is fixedly connected to the screw 216. The spring 220 is sleeved on the outside of the screw 216 and located between the support plate 219 and the mounting base 215. When the thread is not screwed into the mounting base 215, the spring 220 can apply a spring force to the support plate 219, causing it to move the screw 216 away from the mounting base 215, thereby preventing the screw 216 from contacting the slide groove 301 and causing friction, which would affect the movement of the retaining ring 201.

[0051] In some examples, the inner surface of the chute 301 is arc-shaped, and the chute 301 is formed by two inclined and symmetrically arranged arc-shaped support plates. In a specific configuration, a conveyor rail 304 is provided on the platform 100, and the arc-shaped support plates are mounted on the conveyor rail 304 to maintain inclination. This embodiment shows that there is a gap between the two arc-shaped support plates.

[0052] In some examples, the surface of the drive wheel 303 is provided with an anti-slip structure 305 to increase the friction between the drive wheel 303 and the pipe 1 to be processed. In specific configurations, an anti-slip rubber strip can be provided on the surface of the drive wheel 303. This application does not specifically limit the specific implementation of this method.

[0053] In some examples, the pipeline conveying mechanism 300 further includes multiple arc-shaped support plates 306, which are respectively disposed on both sides of the inner wall of the chute 301, and multiple sliding wheels 302 are rotatably disposed on the multiple arc-shaped support plates 306. In specific configurations, each arc-shaped support plate 306 may be provided with one or more sliding wheels 302. This embodiment shows that each arc-shaped support plate 306 is provided with two sliding wheels 302, and the two sliding wheels 302 are arranged circumferentially along the chute 301.

[0054] In some examples, the pipeline conveying mechanism 300 also includes multiple first push rods 307, which are respectively disposed on both sides of the inner wall of the chute 301 and connected to multiple arc-shaped support plates 306. In specific configurations, the first push rods 307 can be pneumatic push rods, electric push rods, etc. The first push rods 307 are disposed on the inner side of the chute 301, and the telescopic rods of the first push rods 307 are connected to the corresponding arc-shaped support plates 306. The first push rods 307 can extend and retract their telescopic rods radially along the fixed ring 201 to drive the arc-shaped support plates 306 and the sliding wheels 302 thereon to move radially along the fixed ring 201.

[0055] In some examples, the pipeline conveying mechanism 300 further includes a support plate 308 located below the chute 301 (between the two conveying rails 304). The support plate 308 has opposing first and second sides, and multiple drive wheels 303 are rotatably mounted on the first side of the support plate 308. In a specific configuration, multiple U-shaped seats 309 are provided on the support plate 308, and the multiple drive wheels 303 are rotatably mounted on the multiple U-shaped seats 309. In this document, the first side and the second side are the upper and lower surfaces of the support plate 308, respectively.

[0056] In some examples, the pipeline conveying mechanism 300 also includes a conveying motor 310 and a transmission mechanism. The transmission mechanism connects multiple drive wheels 303, and the conveying motor 310 is connected to the transmission mechanism. In specific configurations, the transmission mechanism can be a gear chain 312 transmission mechanism. For example, the gear chain 312 transmission mechanism includes multiple gear discs 311 and a chain 312. Each gear disc 311 is respectively mounted on each U-shaped seat 309, and each gear disc 311 is respectively connected to each drive wheel 303. The chain 312 is wound around the multiple gears. When the conveying motor 310 drives any one gear disc 311 to rotate, the chain 312 can drive all gear discs 311 to rotate, thereby driving all drive wheels 303 to rotate. This embodiment of the application does not specifically limit the specific implementation of this feature.

[0057] In some examples, the pipeline conveying mechanism 300 also includes a plurality of second push rods 313, which are respectively disposed on the platform 100 and connected to the second side of the support plate 308. In specific configurations, the second push rods 313 can be pneumatic push rods, electric push rods, etc. The telescopic rods of the second push rods 313 are connected to the back of the support plate 308, and the second push rods 313 can extend and retract their telescopic rods radially along the fixing ring 201 to drive the support plate 308 and the drive wheel 303 thereon to move radially along the fixing ring 201.

[0058] In some examples, the automatic pipe welding beveling device also includes a chip cleaning mechanism 400, which removes chips generated during processing. This prevents metal chips from accumulating on the pipe to be processed 1 and the beveling mechanism 200, helping to keep the equipment clean and improve processing quality.

[0059] In some examples, the debris cleaning mechanism 400 includes an air blowing assembly and a collection box 407. The air blowing assembly blows air onto the processing location of the pipe 1 to dislodge debris. The collection box 407 is disposed on the platform 100 and located below the beveling mechanism 200, and is used to collect the dislodged debris. In use, the debris cleaning mechanism 400 sweeps away metal debris with the air blowing assembly, causing the metal debris to fall into the collection box 407, thereby cleaning the automatic pipe welding beveling device.

[0060] In some examples, the air blowing assembly includes an air tank 401, a nozzle 402, and an air hose. The air tank 401 stores compressed gas, and one end of the air hose is connected to the air tank 401, while the other end is connected to the nozzle 402. In use, the air tank 401 delivers compressed gas through the air hose, and the compressed gas is ultimately ejected through the nozzle 402. In specific configurations, the air blowing assembly may also include an air compressor 406, which is connected to the air tank 401. During operation, the air compression molding machine can fill the air tank 401 with compressed gas.

[0061] In some examples, the blowing direction of the air-blowing assembly is adjustable, that is, the direction of the nozzle 402 is adjustable. Specifically, the air pipes include a first air pipe 403 and a second air pipe 404, which are at an angle (e.g., 90°) and are connected by a rotating connecting shaft 405. In use, by rotating the first air pipe 403 relative to the second air pipe 404, the angle of the nozzle 402 can be changed, thereby changing the blowing direction of the air-blowing assembly.

[0062] In some examples, the collection box 407 is provided with a baffle 408, which is located on the side of the beveling mechanism 200 opposite to the nozzle 402. The baffle 408 is used to intercept debris and cause it to fall into the collection box 407. In this embodiment, the baffle 408 and the nozzle 402 can be located on opposite sides of the axial direction of the retaining ring 201.

[0063] In some examples, the collection bin 407 is movable relative to the platform 100 and has a debris collection position and a debris removal position relative to the platform 100. Specifically, at the debris collection position, the collection bin 407 is used to collect blown-off metal debris, and at the debris removal position, an operator or automated equipment can remove and recycle the metal debris from the collection bin 407.

[0064] In some examples, the collection box 407 is equipped with casters 409 at its bottom. This makes it easy to move the collection box 407.

[0065] In some examples, the platform 100 is provided with a positioning groove 101, and the moving wheels 409 of the collection box 407 are located in the positioning groove 101. That is, when the collection box 407 moves, the positioning groove 101 can position the moving wheels 409 of the collection box 407 to prevent the collection box 407 from deviating from the debris collection position and the debris removal position.

[0066] In some examples, platform 100 is provided with a limiting component to restrict the movement of collection box 407 relative to platform 100. Specifically, the limiting component includes a telescopic cylinder 102 and a limiting block 103. The telescopic cylinder 102 is mounted on platform 100, and the limiting block 103 is mounted on the telescopic rod of the telescopic cylinder 102. The limiting block 103 is used to move into the movement trajectory of the moving wheel 409 when the telescopic cylinder 102 extends or retracts its telescopic rod, thereby restricting the movement of collection box 407.

[0067] One or more embodiments in this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this specification should be included within the protection scope of this application.
