Pipe cutting machine with pipe rotary cutting function

Abstract

The application relates to the technical field of pipeline cutting equipment, and discloses a pipeline cutting machine with a pipeline rotary cutting function, which comprises a fixing frame, a supporting track fixedly connected to the top of the fixing frame, an operation table fixedly connected to the side wall of the fixing frame, and a moving table fixedly connected to the side wall of the fixing frame. After the equipment completes cutting, the pipeline is divided into two parts, namely a body and a cut end. The body is still at the top of the rotating column I, while the cut end will fall down due to the loss of limitation. After the cut end completely separates from the arc-shaped plate, the top of the arc-shaped plate loses pressure, the torsional spring I releases mechanical power at this time, forces the rotating disc and the flame spraying gun to reset at the same time, and is far away from the outer wall of the pipeline, so that the flame spraying gun can quickly move away from the cutting area after the equipment completes cutting, and the high-temperature flame of the flame spraying gun causes small deformation of the edge of the pipeline.

Description

Technical Field

[0001] This invention relates to the field of pipe cutting equipment technology, specifically a pipe cutting machine with pipe rotation cutting function. Background Technology

[0002] Pipelines are needed in the construction of water conservancy projects. Through pipeline construction, surface water and groundwater are regulated and controlled. During pipeline construction, cutting is required to meet construction and installation requirements. The above cutting methods mostly use saw blades or flame cutting.

[0003] During the flame cutting process, as the pipe rotates continuously, the nozzle will complete the cutting process. However, since the flame nozzle needs to be shut down in an orderly manner and the power supply to the equipment needs to be cut off, the flame will remain for a period of time after the cutting is completed. At this time, the flame will scorch the outer wall of the pipe, causing the pipe edge to undergo slight deformation due to high temperature. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a pipe cutting machine with a pipe rotation cutting function, including a fixed frame, a support rail fixedly connected to the top of the fixed frame, an operating table fixedly connected to the side wall of the fixed frame, and a movable table fixedly connected to the side wall of the fixed frame, and further including:

[0005] The pressure mechanism is fixedly connected to the inner wall of the fixed frame and is used to drive the pipe to rotate.

[0006] Steering mechanism, which is fixedly connected to the side wall of the moving platform, is used for flame cutting of pipes;

[0007] The linkage mechanism is fixedly connected to the side wall of the pressure mechanism and is used to contact the outer wall of the pipeline. After the pipeline is cut, it drives the steering mechanism to rotate.

[0008] Before use, the pipe is placed on the inner wall of the fixed frame, and then the operator forces the moving table to drive the steering mechanism to move to the cutting area through the operating table.

[0009] Preferably, the pressure mechanism includes:

[0010] The rolling assembly is fixedly connected to the inner wall of the fixed frame by a support member;

[0011] The support includes a fixing plate that is fixedly connected to the inner wall of the fixing frame, and a mounting platform is fixedly connected to the top of the fixing plate;

[0012] The drive assembly is rotatably connected to the inner wall of the mounting platform via a rotating component;

[0013] The rotating component includes two supporting round rods rotatably connected to the inner wall of the mounting platform, and belts are fitted onto the outer walls of the two supporting round rods.

[0014] Before use, the pipe is placed on top of the rotating column two, and during operation, the rotating column two will drive the pipe to rotate.

[0015] Preferably, the linkage mechanism includes:

[0016] The contact assembly is fixedly connected to the side wall of the mounting platform via a steering component;

[0017] The steering component includes a mounting bracket fixedly connected to the side wall of the mounting platform, and a rotating rod fixedly connected to the inner wall of the mounting bracket;

[0018] The linkage component is fixedly connected to the side wall of the rotating rod via a transmission component;

[0019] The transmission component includes a rotating wheel fixedly connected to the side wall of the rotating rod;

[0020] When the pipe is placed on the inner wall of the mounting platform, the heavy weight of the metal pipe will force the contact assembly to rotate around the rotating rod.

[0021] Preferably, the steering mechanism includes:

[0022] Energy storage component, which is fixedly connected to the side wall of the mobile platform by limiting components;

[0023] The limiting component includes a fixed rod that is fixedly connected to the side wall of the moving platform, and a rotating disk is rotatably connected to the side wall of the fixed rod;

[0024] The spray gun assembly is fixedly connected to the side wall of the rotating disk via a positioning component.

[0025] The positioning component includes a rotating square rod fixedly connected to the side wall of the rotating disk, a flame gun fixedly connected to the side wall of the rotating square rod, and a gas supply pipe connected through the top of the flame gun.

[0026] After the pipe is placed securely, the flame gun sprays flames to cut the outer wall of the pipe, while the rotating column 2 drives the pipe to rotate in a circle, completing the basic cutting process.

[0027] Preferably, the rolling assembly includes a plurality of rotating columns rotatably connected to the inner wall of the mounting platform;

[0028] When the rotating column 2 drives the pipe to rotate, the outer walls of several rotating columns 1 will contact the pipe and assist the pipe in rotating.

[0029] Preferably, the drive assembly includes a CNC motor fixedly connected to the bottom of the fixed plate, an output rod fixedly connected to the output end of the CNC motor, and the end of the belt away from the two supporting round rods being rotatably connected to the outer wall of the output rod;

[0030] The rotational force generated by the CNC motor drives the support rod and the rotating column to rotate in the same direction through the output rod and belt.

[0031] Preferably, the contact assembly includes an arc-shaped plate fixedly connected to the side wall of the rotating rod, and an inclined contact block is fixedly connected to the outer wall of the arc-shaped plate;

[0032] During the placement of the pipe, the outer wall of the inclined contact block comes into contact with the pipe, forcing the arc plate to rotate counterclockwise around the rotating rod, which in turn drives the rotating wheel to rotate.

[0033] Preferably, the linkage component includes a transmission belt sleeved on the outer wall of the rotating wheel, with the end of the transmission belt away from the rotating wheel in contact with the outer side of the rotating disk;

[0034] When the rotating wheel drives the conveyor belt to rotate, the conveyor belt will drive the rotating disk to rotate.

[0035] Preferably, the energy storage component includes a torsion spring 1 fixedly connected to the inner wall of the fixed rod, and the end of the torsion spring 1 away from the fixed rod is fixedly connected to the inner wall of the rotating disk.

[0036] When the rotating disk rotates, it forces the torsion spring to deform and continue to provide mechanical power for the subsequent reset of the spray gun assembly.

[0037] Preferably, the spray gun assembly includes a right-angle rod fixedly connected to the side wall of the rotating square rod, and a right-angle plate fixedly connected to the side wall of the moving table;

[0038] When not in use, the flame gun and the bottom mounting bracket are horizontal. After the pipe is placed on top of the rolling assembly, the pressure generated forces the flame gun to rotate downwards.

[0039] The present invention has the following beneficial effects:

[0040] (1) After the device completes the cutting, the pipe will be divided into two parts: the main body and the cut end. The main body remains at the top of the rotating column, while the cut end, having lost its restraint, will fall downwards, appearing as follows: Figure 11 In this state, after the cut end is completely separated from the arc plate, the torsion spring will release mechanical power due to the loss of pressure at the top of the arc plate, forcing the rotating disk and the flame gun to reset simultaneously and move away from the outer wall of the pipe. Through the application of the above components, it is ensured that the flame gun can quickly move away from the cutting area after the equipment completes the cutting. The high temperature flame of the flame gun causes small deformations on the edge of the pipe.

[0041] (2) This invention utilizes the characteristics of the flame gun for cutting pipes described above, positioning the flame gun at the vertical top of the pipe. Through this design, the flame gun, just before completing the pipe cut, presents the following... Figure 10 The state at this time Figure 10 The position of G is the only remaining connection point between the main body and the cut-off end. At this point, all the pressure from the cut-off end will act on the end of the arc-shaped plate, i.e. Figure 10 The position of L forces the arc plate to always face downwards, ensuring that the flame torch remains perpendicular to the pipe before completing a complete cut. This prevents the arc plate from rotating due to the reduction in the distance between the main body and the cutting end, which would ultimately change the cutting path of the flame torch and affect the flatness of the cutting area.

[0042] (3) The present invention utilizes the rotational characteristics of the above-mentioned rotating square rod to install a right-angle rod and a right-angle plate inside the equipment. When the rotating disk and the rotating square rod rotate, the rotating square rod will drive the right-angle rod to contact the plane of the right-angle plate, so that the flame gun and the right-angle plate form a horizontal state. Through the application of the above components, after the pipe drives the arc plate to rotate downward to the lowest position, the flame gun can form a vertical state with the pipe, which speeds up the positioning efficiency of the equipment in the early stage.

Detailed Implementation

[0057] 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.

[0058] Example 1, please refer to Figures 1-7 This invention relates to a pipe cutting machine with a pipe rotation cutting function, comprising a fixed frame 13, a support rail 14 fixedly connected to the top of the fixed frame 13, an operating table 15 fixedly connected to the side wall of the fixed frame 13, and a movable table 16 fixedly connected to the side wall of the fixed frame 13, and further comprising:

[0059] Pressure mechanism 1 is fixedly connected to the inner wall of the fixed frame 13 and is used to drive the pipe to rotate.

[0060] Steering mechanism 3 is fixedly connected to the side wall of the moving platform 16 and is used for flame cutting of pipes;

[0061] Linkage mechanism 2 is fixedly connected to the side wall of pressure mechanism 1 and is used to contact the outer wall of the pipe. After the pipe is cut, it drives the steering mechanism 3 to rotate.

[0062] Before use, the pipe is placed on the inner wall of the fixed frame 13. Then, the operator uses the operating table 15 to force the moving table 16 to drive the steering mechanism 3 to move to the cutting area.

[0063] Pressure mechanism 1 includes:

[0064] Rolling assembly 11 is fixedly connected to the inner wall of the fixed frame 13 by a support member;

[0065] The support includes a fixing plate 111 fixedly connected to the inner wall of the fixing frame 13, and a mounting platform 112 fixedly connected to the top of the fixing plate 111.

[0066] Drive assembly 12 is rotatably connected to the inner wall of mounting platform 112 via a rotating component;

[0067] The rotating component includes two supporting round rods 122 rotatably connected to the inner wall of the mounting platform 112, and a belt 123 is sleeved on the outer wall of the two supporting round rods 122.

[0068] Before use, the pipe is placed on top of the rotating column 121. During operation, the rotating column 121 will drive the pipe to rotate.

[0069] Linkage mechanism 2 includes:

[0070] Contact component 21 is fixedly connected to the side wall of mounting platform 112 via a steering component;

[0071] The steering component includes a mounting bracket 211 fixedly connected to the side wall of the mounting platform 112, and a rotating rod 212 fixedly connected to the inner wall of the mounting bracket 211;

[0072] Linkage component 22 is fixedly connected to the side wall of rotating rod 212 via a transmission component;

[0073] The transmission component includes a rotating wheel 221 fixedly connected to the side wall of the rotating rod 212;

[0074] When the pipe is placed on the inner wall of the mounting platform 112, due to the large weight of the metal pipe, the pipe will force the contact assembly 21 to rotate around the rotating rod 212.

[0075] Steering mechanism 3 includes:

[0076] Energy storage component 31 is fixedly connected to the side wall of the mobile platform 16 by a limiting member;

[0077] The limiting component includes a fixing rod 311 fixedly connected to the side wall of the moving platform 16, and a rotating disk 312 rotatably connected to the side wall of the fixing rod 311;

[0078] The spray gun assembly 32 is fixedly connected to the side wall of the rotating disk 312 by a positioning member;

[0079] The positioning component includes a rotating square rod 321 fixedly connected to the side wall of the rotating disk 312, a flame gun 322 fixedly connected to the side wall of the rotating square rod 321, and a gas supply pipe 323 connected through the top of the flame gun 322.

[0080] After the pipe is placed securely, the flame gun 322 sprays flames to cut the outer wall of the pipe, while the rotating column 121 drives the pipe to rotate in a circle to complete the basic cutting process.

[0081] The operator uses the control panel 15 to force the moving table 16 to drive the steering mechanism 3 to move to the cutting area. After confirming the cutting position, the flame gun 322 is activated, forcing the flame gun 322 to spray flames onto the outer wall of the pipe. At this time, the CNC motor 124 drives the support rod 122 and the rotating column 121 to rotate through the output rod 125 and the belt 123. The rotating column 121 will force the pipe at the top to rotate, changing the cutting position of the flame gun 322 on the pipe.

[0082] Example 2, please refer to Figures 3-11 The present invention is a pipe cutting machine with pipe rotation cutting function. Based on Example 1, the rolling assembly 11 includes a plurality of rotating columns 113 rotatably connected to the inner wall of the mounting platform 112.

[0083] When the rotating column 2 121 drives the pipe to rotate, the outer walls of several rotating columns 113 will contact the pipe and assist the pipe to rotate.

[0084] As the pipe is placed on top of the rolling assembly 11, the pressure of the pipe itself will force the arc plate 213 to rotate counterclockwise, presenting a shape as shown. Figure 5 In this state, the arc plate 213 drives the rotating wheel 221 to rotate in the same direction through the rotating rod 212, and the rotating wheel 221 drives the rotating disk 312 to rotate along the outer wall of the fixed rod 311 through the transmission belt 222. At the same time, the torsion spring 313 is compressed and deformed. The rotating disk 312 drives the flame gun 322 to be perpendicular to the outer wall of the pipe through the rotating square rod 321, so that the flame gun 322 enters the cutting state.

[0085] The drive assembly 12 includes a CNC motor 124 fixedly connected to the bottom of the fixed plate 111. The output end of the CNC motor 124 is fixedly connected to an output rod 125. The end of the belt 123 away from the two supporting round rods 122 is rotatably connected to the outer wall of the output rod 125.

[0086] The rotational force generated by the CNC motor 124 drives the support rod 122 and the rotating column 121 to rotate in the same direction through the output rod 125 and the belt 123.

[0087] After the equipment completes the cutting, the pipe will be divided into two parts: the main body and the cut end. The main body will remain at the top of the rotating column 113, while the cut end, no longer restrained, will fall downwards, appearing as follows: Figure 11 In the state where the cut end is completely separated from the arc plate 213, the torsion spring 313 will release mechanical power as the top of the arc plate 213 loses pressure, forcing the rotating disk 312 and the flame gun 322 to reset simultaneously and move away from the outer wall of the pipe. Through the application of the above components, it is ensured that after the equipment completes the cutting, the flame gun 322 can quickly move away from the cutting area. The high temperature flame of the flame gun 322 causes small deformations on the edge of the pipe.

[0088] The contact assembly 21 includes an arc-shaped plate 213 fixedly connected to the side wall of the rotating rod 212, and an inclined contact block 214 fixedly connected to the outer wall of the arc-shaped plate 213;

[0089] During the placement of the pipe, it contacts the outer wall of the inclined contact block 214, forcing the arc plate 213 to rotate counterclockwise around the rotating rod 212, and driving the rotating wheel 221 to rotate.

[0090] Utilizing the pipe-cutting characteristics of the flame gun 322, the flame gun 322 is positioned at the vertical top of the pipe. Through this design, the flame gun 322, as it approaches the completion of the pipe cut, presents the following... Figure 10 The state at this time Figure 10 The position of G is the only remaining connection point between the main body and the cut-off end. At this point, all the pressure from the cut-off end will act on the end of the arc-shaped plate 213, that is... Figure 10 The position of L forces the arc plate 213 to always face downwards, ensuring that the flame gun 322 remains perpendicular to the pipe before completing the cut. This prevents the arc plate 213 from rotating due to the reduced distance between the body and the cutting end, which would ultimately cause changes in the cutting path of the flame gun 322 and affect the flatness of the cutting area.

[0091] The linkage component 22 includes a transmission belt 222 sleeved on the outer wall of the rotating wheel 221, with one end of the transmission belt 222 away from the rotating wheel 221 in contact with the outer wall of the rotating disk 312;

[0092] When the rotating wheel 221 drives the transmission belt 222 to rotate, the transmission belt 222 will drive the rotating disk 312 to rotate.

[0093] The energy storage assembly 31 includes a torsion spring 313 fixedly connected to the inner wall of the fixed rod 311, and the end of the torsion spring 313 away from the fixed rod 311 is fixedly connected to the inner wall of the rotating disk 312.

[0094] When the rotating disk 312 rotates, it will force the torsion spring 313 to deform and accumulate mechanical power to provide power for the subsequent reset of the spray gun assembly 32.

[0095] The spray gun assembly 32 includes a right-angle rod 324 fixedly connected to the side wall of the rotating square rod 321, and a right-angle plate 325 fixedly connected to the side wall of the moving table 16.

[0096] When the spray gun assembly 32 is not in use, the flame spray gun 322 and the bottom fixing bracket 13 are in a horizontal state. After the pipe is placed on top of the rolling assembly 11, the pressure generated forces the flame spray gun 322 to rotate downward.

[0097] Taking advantage of the rotational characteristic of the aforementioned rotating square rod 321, a right-angle rod 324 and a right-angle plate 325 are installed inside the equipment. When the rotating disk 312 and the rotating square rod 321 rotate, the rotating square rod 321 will drive the right-angle rod 324 to make planar contact with the right-angle plate 325, so that the flame gun 322 and the right-angle plate 325 form a horizontal state. Through the application of the above components, after the pipeline drives the arc plate 213 to rotate downward to the lowest position, the flame gun 322 can form a perpendicular state with the pipeline, which speeds up the positioning efficiency of the equipment in the early stage.

[0098] One specific application of this embodiment is as follows: Before use, the pipe is placed on top of the two sets of pressure mechanisms 1, resulting in the following arrangement: Figure 1 In this state, part of the pipe will press against the arc plate 213, forcing the arc plate 213 to rotate around the rotating rod 212. After the operator confirms that the rotating column 2121 can drive the pipe to rotate, the operator uses the operating table 15 to force the moving table 16 to drive the steering mechanism 3 to move to the cutting area. After confirming the cutting position, the flame gun 322 is started, forcing the flame gun 322 to spray flames onto the outer wall of the pipe. At this time, the CNC motor 124 drives the support rod 122 and the rotating column 2121 to rotate through the output rod 125 and the belt 123. The rotating column 2121 will force the pipe at the top to rotate, changing the cutting position of the flame gun 322 on the pipe.

[0099] During the process of placing the pipe on top of the rolling assembly 11, the pressure of the pipe itself will force the arc plate 213 to rotate counterclockwise, presenting a shape as shown. Figure 5 In this state, the arc plate 213 drives the rotating wheel 221 to rotate in the same direction through the rotating rod 212, and the rotating wheel 221 drives the rotating disk 312 to rotate along the outer wall of the fixed rod 311 through the transmission belt 222. At the same time, the torsion spring 313 is compressed and deformed. The rotating disk 312 drives the flame gun 322 to be perpendicular to the outer wall of the pipe through the rotating square rod 321, so that the flame gun 322 enters the cutting state.

[0100] After the equipment completes the cutting, the pipe will be divided into two parts: the main body and the cut end. The main body will remain at the top of the rotating column 113, while the cut end, no longer restrained, will fall downwards, appearing as follows: Figure 11 In the state of F, after the cut end is completely separated from the arc plate 213, the torsion spring 313 will release mechanical power due to the loss of pressure at the top of the arc plate 213, forcing the rotating disk 312 and the flame gun 322 to reset simultaneously and move away from the outer wall of the pipe. Through the application of the above components, it is ensured that after the equipment completes the cutting, the flame gun 322 can quickly move away from the cutting area. The high temperature flame of the flame gun 322 causes small deformations on the edge of the pipe.

[0101] Utilizing the pipe-cutting characteristics of the flame gun 322, the flame gun 322 is positioned at the vertical top of the pipe. Through this design, the flame gun 322, as it approaches the completion of the pipe cut, presents the following... Figure 10 The state at this time Figure 10 The position of G is the only remaining connection point between the main body and the cut-off end. At this point, all the pressure from the cut-off end will act on the end of the arc-shaped plate 213, that is... Figure 10 The position of L forces the arc plate 213 to always face downwards, ensuring that the flame gun 322 remains perpendicular to the pipe before completing a complete cut. This prevents the arc plate 213 from rotating due to the reduction in the distance between the body and the cutting end, which would ultimately cause changes in the cutting path of the flame gun 322 and affect the flatness of the cutting area.

[0102] Taking advantage of the rotational characteristic of the aforementioned rotating square rod 321, a right-angle rod 324 and a right-angle plate 325 are installed inside the equipment. When the rotating disk 312 and the rotating square rod 321 rotate, the rotating square rod 321 will drive the right-angle rod 324 to make planar contact with the right-angle plate 325, so that the flame gun 322 and the right-angle plate 325 form a horizontal state. Through the application of the above components, after the pipeline drives the arc plate 213 to rotate downward to the lowest position, the flame gun 322 can form a perpendicular state with the pipeline, which speeds up the positioning efficiency of the equipment in the early stage.
