Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically, to a pipe cutting device. Background Technology

[0002] Hose connections are a type of connection that uses flexible pipes and their accessories to transmit fluids or sometimes power in mechanical, equipment, or piping systems. They solve problems that rigid connections struggle with, such as vibration, displacement, and installation errors. They are used in various fields, such as motorcycle braking systems. When installing hoses, connectors are usually installed at both ends of the pipe for connection. During processing, the hose needs to be pulled out to the required length, cut, and then transferred to other equipment for chamfering, assembly, riveting, and other processing. The cutting process usually requires manual loading, cutting, unloading, and conveying, which is very troublesome, wastes manpower, and is inefficient. Utility Model Content

[0003] In summary, to overcome the shortcomings of the prior art, this utility model provides a pipe cutting device that can automatically feed, cut, and then unload and convey the pipe.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipe cutting device, comprising a feeding mechanism, a cutting mechanism, a discharging mechanism, and a conveying mechanism. The feeding mechanism is connected to the cutting mechanism, and the discharging mechanism is connected to the cutting mechanism and the conveying mechanism. The cutting mechanism includes a cutting disc and a support rod, with the cutting disc facing the support rod. The discharging mechanism includes a first driving member, which controls the support rod to reciprocate in the direction of the conveying mechanism.

[0005] With this setup, when the machine is started, the feeding mechanism will transport the tube material to the support rod. Then, the cutting disc is rotated by the motor and pushed by a push rod or similar component to insert into the side of the support rod, or a groove is provided on the support rod for the cutting disc to insert into. This allows the tube on the support rod to be cut. After the tube is cut to the required length, it will remain on the support rod. At this point, the first drive component will control the support rod to rotate toward the conveying mechanism, pouring the tube on the support rod onto the conveying mechanism. Then, the support rod will rotate back to its original position for the next tube cutting. A cover can also be installed on the cutting disc for added safety. No manual operation is required, and the efficiency is high.

[0006] Furthermore, the feeding mechanism also includes a first drive rod, which is rotatably connected to the frame, and the support rod is connected to the first drive rod. The first drive component is a motor, and the first drive rod is connected to the output shaft of the first drive component.

[0007] With this configuration, the use of a rod-shaped first drive rod as the main rotating component makes it easier to connect with the frame. This allows the support rod to be freely configured into the required shape for convenient placement of the tube and cutting.

[0008] Furthermore, the feeding mechanism also includes a support hook, which is hook-shaped and positioned below the support rod facing the conveying mechanism.

[0009] With this setup, the cut pipe will first fall onto the support hook and stay there temporarily. Since the support hook is a checkmark shape, the pipe will fall at the corner of the checkmark. This will help to position the pipe and prevent it from falling over due to gravity, making it easier for the conveying mechanism to transport it away.

[0010] Furthermore, the feeding mechanism also includes a second driving member and a second driving rod. The support hook is connected to the second driving rod, and the second driving rod is rotatably connected to the frame. The second driving member controls the second driving rod to reciprocate in the direction of the conveying mechanism.

[0011] With this configuration, when the conveying mechanism comes into contact with the tube on the support hook, the second drive unit can control the second drive rod to rotate, causing the support hook on the second rotating rod to swing downward. In this way, the conveying mechanism does not need to be raised during conveying; it can simply move horizontally to remove the tube from the support hook.

[0012] Furthermore, the cutting mechanism also includes a positioning block, and the support rod is provided with a conveying groove, the positioning block being adapted to the conveying groove.

[0013] This design makes it easier to place the pipe inside the conveying trough, which makes the pipe cutting process more stable. The positioning block can position the pipe inside the conveying trough after it reaches a certain length on the support rod.

[0014] Furthermore, the cutting mechanism also includes a first push-pull mechanism, which controls the positioning block to reciprocate on the support rod toward the conveying groove.

[0015] With this setup, during cutting, the first push-pull machine will drive the positioning block to insert it into the conveying groove. After cutting, the first push-pull machine will pull the positioning block out of the conveying groove. At this time, the support rod can rotate freely and will not be stuck by the positioning block. The first push-pull machine can also be equipped with an infrared sensor for greater sensitivity. The first push-pull machine can use conventional push-pull parts such as telescopic motors, telescopic cylinders, and hydraulic cylinders. Other push-pull machines in this application can also use the same selection as the first push-pull machine.

[0016] Furthermore, the conveying mechanism includes a second push-pull mechanism, a sliding rod, and several clamping components. The several clamping components are connected to the sliding rod, and the second push-pull mechanism controls the sliding rod to reciprocate in the direction away from the cutting mechanism.

[0017] With this setup, the clamping assembly can hold the tube falling from the unloading mechanism. Then, the second push-pull machine will operate, pushing the sliding rod to move the tube to the next station. At this time, the parts at other stations will fix the tube for processing. The clamping assembly can then release the tube, and the second push-pull machine will pull the sliding rod back to clamp the next falling tube. After the tube is processed by other stations, it will be clamped by other clamping assemblies on the sliding rod after being released by the station. This process is repeated to continuously transport the tube to the next position. The conveying mechanism requires less space and has a higher space utilization rate.

[0018] Furthermore, the clamping assembly includes a third drive member and two opposing clamping jaws, the third drive member controlling the clamping jaws to move toward the other clamping jaw.

[0019] With this setup, the tube will fall between the two clamping jaws, and then the third drive unit can control the two clamping jaws to retract, thus clamping the tube between them and ensuring stable clamping.

[0020] Furthermore, the conveying mechanism also includes a support plate, which is connected to a plurality of the clamping assemblies.

[0021] With this configuration, the support plate can be used to support and stabilize the height of the tube, keeping it in the gripping position of the clamping jaws. This way, even if the clamping jaws release the tube, the tube will not fall and will always maintain this height before being clamped by the clamping parts of other stations, resulting in more stable processing.

[0022] Furthermore, the feeding mechanism also includes a guide plate, which is located between the feeding mechanism and the conveying mechanism, and the guide plate is provided with a guide channel.

[0023] With this configuration, the guide channel on the guide plate can guide the pipe that is being dumped by the feeding mechanism, preventing it from bouncing around. The guide channel can be formed by slotting a plate or by installing two plates one above the other with a gap between them. Attached Figure Description

Detailed Implementation

[0031] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0032] Referring to the accompanying drawings, this utility model provides the following technical solution: a pipe cutting device, including a feeding mechanism 201, a cutting mechanism 202, a discharging mechanism 203, and a conveying mechanism 204. The feeding mechanism 201 is connected to the cutting mechanism 202, and the discharging mechanism 203 is connected to the cutting mechanism 202 and the conveying mechanism 204. The cutting mechanism 202 includes a cutting disc 2021 and a support rod 2022. The cutting disc 2021 is disposed facing the support rod 2022. The discharging mechanism 203 includes a first driving member 2031, which controls the support rod 2022 to reciprocate in the direction of the conveying mechanism 204.

[0033] With this setup, the feeding mechanism 201 will transport the tube to the support rod 2022. Then, the cutting disc 2021 is rotated by the motor and pushed by a push rod or similar component to insert into the side of the support rod 2022. Alternatively, the support rod 2022 can have a groove for the cutting disc 2021 to insert into, thus cutting the tube on the support rod 2022. After cutting, the tube of the required length will remain on the support rod 2022. At this point, the first driving component 2031 will control the support rod 2022 to rotate toward the conveying mechanism 204, pouring the tube on the support rod 2022 onto the conveying mechanism 204. Then, the support rod 2022 will rotate back to its original position for the next tube cutting. A cover can also be installed on the cutting disc 2021 for added safety, eliminating the need for manual operation and increasing efficiency.

[0034] In a preferred embodiment, the unloading mechanism 203 further includes a first drive rod 2032, which is rotatably connected to the frame 1. The support rod 2022 is connected to the first drive rod 2032. The first drive component 2031 is a motor, and the first drive rod 2032 is connected to the output shaft of the first drive component 2031. The above configuration is not limited. The first drive component 2031 can also be a push rod, which drives the support rod 2022 to rotate by pushing, or other conventional parts can be used for driving. Other drive components that control rotation in this application can be selected in the same way as the first drive component 2031.

[0035] With this configuration, the first drive rod 2032, which is rod-shaped, is selected as the main rotating component, making it easier to rotate and connect with the frame 1. In this way, the support rod 2022 can be freely set into the required shape to facilitate the placement of the tube and cutting.

[0036] In a preferred embodiment, the feeding mechanism 203 further includes a support hook 2033, which is hook-shaped and is positioned below the support rod 2022 and facing the conveying mechanism 204.

[0037] With this setup, the cut pipe will first fall onto the support hook 2033 and stay there temporarily. Since the support hook 2033 is a checkmark shape, the pipe will fall at the corner of the checkmark. This will help to position the pipe and prevent it from falling over due to gravity, making it easier for the conveying mechanism 204 to transport it away.

[0038] In a preferred embodiment, the feeding mechanism 203 further includes a second driving member 2034 and a second driving rod 2035. The support hook 2033 is connected to the second driving rod 2035, and the second driving rod 2035 is rotatably connected to the frame 1. The second driving member 2034 controls the second driving rod 2035 to reciprocate in the direction of the conveying mechanism 204.

[0039] With this configuration, when the conveying mechanism 204 contacts the tube on the support hook 2033, the second driving member 2034 can control the second driving rod 2035 to rotate, causing the support hook 2033 on the second rotating rod to swing downward. In this way, the conveying mechanism 204 does not need to be raised during conveying; it can simply move horizontally to remove the tube from the support hook 2033.

[0040] In this preferred embodiment, the cutting mechanism 202 further includes a positioning block 2023, and the support rod 2022 is provided with a conveying groove 20221. The positioning block 2023 is adapted to the conveying groove 20221. The above setting is not limited, and the positioning block 2023 can also be directly set on the support rod 2022 without the conveying groove 20221.

[0041] With this configuration, the conveying trough 20221 is more convenient for placing the pipe inside, making the pipe cutting process more stable. The positioning block 2023 can position the pipe inside the conveying trough 20221, positioning it after the pipe reaches a certain length on the support rod 2022.

[0042] In a preferred embodiment, the cutting mechanism 202 further includes a first push-pull mechanism 2024, which controls the positioning block 2023 to reciprocate on the support rod 2022 toward the conveying groove 20221. The above setting is not limited. One of the first push-pull mechanism 2024 and one of the positioning block 2023 can be set at each end of the support rod 2022, so that the positioning and cutting at both ends is more stable. The positioning block 2023 can also be directly set in the conveying groove 20221 and then a slot adapted to the tube body is set.

[0043] With this configuration, during cutting, the first push-pull machine 2024 will drive the positioning block 2023 to insert it into the conveying groove 20221. After cutting, the first push-pull machine 2024 will pull the positioning block 2023 out of the conveying groove 20221. At this time, the support rod 2022 can rotate freely and will not be stuck by the positioning block 2023. The first push-pull machine 2024 can also be equipped with an infrared sensor for greater sensitivity. The first push-pull machine 2024 can use conventional push-pull parts such as telescopic motors, telescopic cylinders, and hydraulic cylinders. Other push-pull machines in this application can also use the same selection as the first push-pull machine 2024.

[0044] In this preferred embodiment, the positioning block 2023 is slidably connected to the frame 1 in the conveying direction of the conveying groove 20221.

[0045] This configuration allows the position of the positioning block 2023 to be changed to accommodate different tube lengths. A sliding connection can be achieved by setting a long rod so that the positioning block 2023 or the first push-pull machine 2024 can slide on the long rod.

[0046] In a preferred embodiment, the conveying mechanism 204 includes a second push-pull mechanism 2041, a sliding rod 2042, and a plurality of clamping components 2043. The plurality of clamping components 2043 are connected to the sliding rod 2042, and the second push-pull mechanism 2041 controls the sliding rod 2042 to reciprocate in a direction away from the cutting mechanism 202.

[0047] With this configuration, the clamping component 2043 can clamp the tube falling from the unloading mechanism 203. Then, the second push-pull machine 2041 will operate, pushing the sliding rod 2042 to move the tube to the next station. At this time, the parts at other stations will fix the tube for processing. Then, the clamping component 2043 can release the tube. Then, the second push-pull machine 2041 will pull the sliding rod 2042 back to clamp the next falling tube. After the tube is processed by other stations, it will be clamped by other clamping components 2043 on the sliding rod 2042 after being released by the station. This process is repeated to continuously transport the tube to the next position. The conveying mechanism 204 requires less space and has a higher space utilization rate.

[0048] In a preferred embodiment, the clamping assembly 2043 includes a third driving member 20431 and two opposing clamping claws 20432. The third driving member 20431 controls the clamping claws 20432 to move toward the other clamping claw 20432.

[0049] With this setup, the tube will fall between the two clamping claws 20432, and then the third drive unit 20431 can control the two clamping claws 20432 to retract, thus clamping the tube between them and ensuring stable clamping.

[0050] In this preferred embodiment, the clamping claw 20432 is rotatably connected to the third driving member 20431.

[0051] With this configuration, the gripper 20432 is in the unfolded state with both sides facing down, which does not occupy its top support surface and makes it easier to pass under the pipe being processed when moving. The third drive unit 20431 can be driven by pneumatic, electric or other means.

[0052] In this preferred embodiment, the two clamping claws 20432 are provided with a plurality of interleaved V-shaped clamping blocks 204321 on the side facing each other.

[0053] With this configuration, the V-shaped clamping block 204321 can clamp the tube body at the bend of the V-shape, making it more stable, and the clamping claws 20432 will not shift after being clamped by the staggered configuration.

[0054] In a preferred embodiment, the conveying mechanism 204 further includes a support plate 2044, which is connected to a plurality of the clamping components 2043.

[0055] With this configuration, the support plate 2044 can be used to support and stabilize the height of the tube, keeping it at the folded position of the V-shaped clamping block 204321. This way, even if the clamping claw 20432 releases the tube, the tube will not fall and will always maintain this height before being clamped by the clamping parts of other stations, making the processing more stable.

[0056] In this preferred embodiment, there are two conveying mechanisms 204, which are respectively arranged on both sides of the frame 1.

[0057] With this configuration, two conveying mechanisms 204 support the tube from both sides, allowing for the transport of long tubes through the small-volume conveying mechanisms 204.

[0058] In this preferred embodiment, the frame 1 is provided with a plurality of support bars 101 located between the two conveying mechanisms 204.

[0059] With this configuration, the support bar 101 can support the suspended tube and prevent it from bending and falling from the middle.

[0060] In this preferred embodiment, the frame 1 is provided with a plurality of sliding blocks 102, and the sliding rod 2042 is connected to the sliding block 102 via a track.

[0061] With this configuration, the sliding rod 2042 will use a track rod with an irregular cross-section, and the sliding block 102 will be provided with a matching slot for insertion. This allows the track connection to make the sliding rod 2042 slide on the frame 1 while driving all the clamping components 2043 to move together, resulting in stable movement.

[0062] In a preferred embodiment, the feeding mechanism 203 further includes a guide plate 2036, which is located between the feeding mechanism 203 and the conveying mechanism 204, and the guide plate 2036 is provided with a guide channel 20361.

[0063] With this configuration, the guide channel 20361 on the guide plate 2036 can guide the pipe that is tilted down by the feeding mechanism 203, preventing it from bouncing around. The guide channel 20361 can be formed by slotting a plate or by installing two plates one above the other with a gap.

[0064] In a preferred embodiment, the feeding mechanism 201 includes a fourth driving member 2011 and two conveying wheels 2012, wherein the fourth driving member 2011 controls the two conveying wheels 2012 to rotate in opposite directions.

[0065] With this setup, the two conveyor wheels 2012 will clamp the tube body, and when they rotate in opposite directions, they will transport the tube body to the same direction, namely the cutting mechanism 202. The structure is simple. The two conveyor wheels 2012 can be driven by two independent motors, or by one motor and two gears meshing together. Several guide wheels can also be set in front of the conveyor wheels 2012 to straighten the tube body and transport it stably. A pipe can also be set between the conveyor wheels 2012 and the cutting mechanism 202 to allow the tube body to pass through, thereby straightening the flexible tube and preventing it from bending during cutting.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto.
