Description

Technical Field

[0001] This invention relates to the field of pipe cutting device technology, and specifically to an automatic pipe cutting device for nylon pipes used in liquid-cooled energy storage systems. Background Technology

[0002] The liquid-cooled energy storage system uses nylon tubing, which is lightweight and has excellent mechanical properties. Nylon material has good corrosion resistance to coolant, a long service life, and can maintain the chemical stability of coolant. The use of nylon hoses requires cutting them into regular sections first. Existing pipe cutting devices can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] Patent application CN109968419A discloses a medical tube cutting machine. Its technical solution includes: a base plate and a frame fixed to the base plate. A cutting blade driven and lifted by a power source is mounted on the frame. The base plate is bolted to a guide structure for clamping the tube to be cut. The guide structure includes a pair of spaced-apart guide blocks, the gap between the two guide blocks forming a slit. The cutting blade is vertically aligned with the slit. One or more pairs of guide positioning grooves for clamping the tube to be cut are correspondingly formed on the two guide blocks. A guide measuring mechanism for measuring the cutting length of the tube to be cut is mounted on the base plate, and the guide measuring mechanism is connected horizontally to the guide positioning grooves. Its advantages are: simple structure, suitable for cutting various tubes of different diameters and materials, small cutting length error, and high cutting accuracy; the two guide blocks of the guide structure simultaneously support the tube, ensuring that the blade can cut the tube perpendicularly when it descends, ensuring a flush cut and improving tube utilization.

[0004] In the prior art as described in the above patent, the cut of the tube is guaranteed to be flush. However, during the retraction process of the cutter, it is easy to slip and rub against the cut surface of the tube. In particular, nylon tubes containing nylon material are prone to generating fine debris under such friction. Therefore, there is an urgent need for an automatic tube cutting device for nylon tubes in liquid-cooled energy storage systems to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pipe cutting device for nylon pipes in liquid-cooled energy storage systems, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic pipe cutting device for nylon tubing in a liquid-cooled energy storage system includes a base, a cutting platform on the base, and a cutting blade that is raised and lowered above the cutting platform. It also includes two clamping wheels symmetrically arranged on the cutting platform, through which the nylon tubing is clamped and passed. A linkage assembly is used to link the raising and lowering of the cutting blade with the rotation of the clamping wheels. When the cutting blade descends, the clamping wheels remain stationary. When the cutting blade descends to its lowest position, the two clamping wheels rotate in linkage to pull the nylon tubing away from the cutting blade. When the cutting blade rises again, the two clamping wheels rotate in linkage to return to their original position.

[0008] Preferably, a first support is fixedly provided on one side of the cutting table, and a first telescopic unit is installed on the first support. The telescopic end of the first telescopic unit is connected to the cutting blade through a first blade holder.

[0009] Preferably, the linkage component includes a linkage gear coaxially connected to the shaft of the clamping wheel, and a linkage block that is slidably connected to the cutting table is meshed between the two linkage gears.

[0010] Preferably, the linkage component includes a linkage rod that is elastically rotatably mounted on the base. The rotation of the linkage rod is linked to the lifting and lowering of the first tool holder. A linkage element is threaded onto the linkage rod. The linkage element is elastically movably connected to the linkage block. A time-delayed limiting component that limits the movement of the linkage block is provided on the base. When the first tool holder descends to the lowest position, the time-delayed limiting component cancels the limit.

[0011] Preferably, one end of the linkage rod is connected to the base via a coil spring, and the other end is coaxially connected to a first trigger wheel. A first rack matching the first trigger wheel is provided on one side of the first tool holder.

[0012] Preferably, the delay limiting component includes an undulating member that is elastically and dynamically mounted on the base. The upper end of the undulating member extends to the side wall of the first support and is located in the lifting stroke of the first tool holder. The lower end of the undulating member extends to the lower side of the linkage block and is fixedly mounted with a locking block. The bottom of the linkage block is provided with a locking groove that matches the locking block.

[0013] Preferably, the base is provided with a drilling platform, and a drilling knife is provided above the drilling platform.

[0014] Preferably, the punching table is provided with a locator, and the locator is provided with a guide sleeve corresponding to the punching knife. The nylon tube passes through the locator and then passes between the two clamping wheels.

[0015] Preferably, a second support is fixedly provided on the base, and a second telescopic unit is installed on the second support. The telescopic end of the second telescopic unit is connected to the drilling knife through a second tool holder.

[0016] Preferably, a second rack is fixedly provided on one side of the second tool holder, and a second trigger wheel matching the second rack is coaxially connected to the linkage rod, with the first rack and the second rack located on opposite sides of the linkage rod.

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] The automatic nylon tube cutting device for this liquid-cooled energy storage system uses a linkage component. During the tube cutting process, the two clamping rollers remain stationary, allowing the nylon tube to be cut smoothly. When the cutter finishes cutting and descends to its lowest position, the linkage component triggers the two clamping rollers to rotate, pulling the nylon tube away from the cutter. This ensures that the cut surface of the nylon tube is away from the cutter. Subsequently, during the cutter's ascent, the two clamping rollers slowly rotate back, preventing the cutter from scraping the cut surface of the nylon tube and avoiding the generation of small debris.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Please see Figures 1-7 This invention provides an automatic pipe cutting device for nylon tubing in a liquid-cooled energy storage system, comprising a base 1, a cutting platform 2 on the base 1, a cutting blade 3 raised and lowered above the cutting platform 2, and further comprising: two clamping wheels 4 symmetrically arranged on the cutting platform 2 for rotatability, through which the nylon tubing is clamped; and a linkage component for linking the raising and lowering of the cutting blade 3 with the rotation of the clamping wheels 4. When the cutting blade 3 descends, the clamping wheels 4 remain stationary. When the cutting blade 3 descends to its lowest position, the two clamping wheels 4 rotate in linkage to pull the nylon tubing away from the cutting blade 3. When the cutting blade 3 rises again, the two clamping wheels 4 rotate in linkage.

[0032] Specifically, the automatic pipe cutting device is integrated into the working chamber. A pipeline conveying device is located at its front end, and a discharge port is located at its rear end. The pipeline conveying device delivers nylon tubing to the automatic pipe cutting device at a fixed length as required, and the discharge port is used to discharge the cut nylon tubing. The nylon tubing is a flexible tube with a nylon layer. The base 1 supports the entire device. The cutting table 2 is divided into two layers, arranged in a stepped shape. The cutter 3 is positioned parallel to the stepped drop surface of the cutting table 2, thus cooperating with the cutting table 2 to form a shearing function to cut the target nylon tubing. The clamping rollers 4 are axially vertical, with flanges at the upper and lower ends. When the clamping rollers 4 are stationary, the outer diameter of the part of the surface in contact with the nylon tubing is reduced by 1-2 mm compared to other surfaces, and it is smoother. Therefore, when the clamping rollers 4 are stationary, the nylon tubing is more easily driven by the pipeline conveying device through the two clamping rollers 4. When the two clamping rollers 4 rotate, the nylon tubing is more easily driven through the other surfaces. The two clamping rollers 4 rotate synchronously and symmetrically. Through a linkage component, when the cutter 3 descends, the clamping rollers 4 are stationary, meaning the nylon tubing... The cutter remains in a cutting state even without any movement, ensuring a clean cut. When the cutter 3 descends to its lowest position, it rises back up. At the same time, the two clamping wheels 4 are triggered to rotate rapidly under the action of the linkage component, pulling the nylon tube away from the cutter 3, that is, making the cut surface of the nylon tube move away from the cutter 3 a certain distance. Then the cutter 3 begins to rise, and the two clamping wheels 4 rotate in linkage, causing the nylon tube to slowly relax towards the cutter 3. During this process, the nylon tube is completely relaxed only after the cutter 3 has left the height of the nylon tube. In practical use, the nylon tube is conveyed to a fixed length and then stops after passing through the two clamping rollers 4 for a certain length. Then the cutter 3 descends. During the descent of the cutter 3, the two clamping rollers 4 remain stationary, and the nylon tube also remains stationary, ensuring smooth cutting and a clean cut surface. When the cutter 3 has finished cutting the tube and descended to its lowest position, the linkage component triggers the two clamping rollers 4 to rotate, pulling the nylon tube away from the cutter 3, so that the cut surface of the nylon tube is away from the cutter 3. Subsequently, during the ascent of the cutter 3, the two clamping rollers 4 slowly rotate back, and the phenomenon of the cutter 3 scraping the cut surface of the nylon tube will not occur, thus avoiding the generation of small debris.

[0033] Compared with the prior art, the automatic pipe cutting device for nylon pipes in a liquid-cooled energy storage system proposed in this embodiment of the invention, by setting up a linkage component, allows the two clamping rollers 4 to remain stationary during the pipe cutting process when the cutter 3 descends, so that the nylon pipe remains stationary for smooth cutting. When the cutter 3 has completed the pipe cutting and descended to the lowest position, the linkage component triggers the two clamping rollers 4 to rotate to pull the nylon pipe away from the cutter 3, so that the cross-section of the nylon pipe is away from the cutter 3. Subsequently, during the process of the cutter 3 rising, the two clamping rollers 4 slowly rotate back, so that the cutter 3 will not scrape the cross-section of the nylon pipe and avoid the generation of fine debris.

[0034] As a preferred technical solution in this embodiment, a first support 5 is fixedly provided on one side of the cutting table 2, and a first telescopic unit 6 is installed on the first support 5. The telescopic end of the first telescopic unit 6 is connected to the cutter 3 through the first cutter holder 7. Specifically, the output end of the first telescopic unit 6 is vertically downward, and the first telescopic unit 6 is preferably a cylinder. The first cutter holder 7 is slidably connected to a slide rail provided on the first support 5. The output end of the first telescopic unit 6 extends and retracts to drive the first cutter holder 7 and the cutter 3 to move up and down.

[0035] As a preferred technical solution of this embodiment, the linkage component includes a linkage gear 8 coaxially connected to the rotating shaft of the clamping wheel 4. A linkage block 9 is meshed between the two linkage gears 8 and slidably connected to the cutting table 2. Specifically, a slider is fixedly provided on the upper end of the linkage block 9, and a sliding groove matching the slider is provided on the cutting table 2. Teeth are provided on opposite sides of the linkage block 9 to mesh with the linkage gears 8 on both sides, thereby making the linkage gears 8 on both sides rotate synchronously and symmetrically, that is, the two clamping wheels 4 rotate synchronously and symmetrically.

[0036] As a preferred technical solution in this embodiment, the linkage component includes a linkage rod 10 elastically rotatably mounted on the base 1. The rotation of the linkage rod 10 is linked to the lifting and lowering of the first tool holder 7. A linkage member 11 is threadedly connected to the linkage rod 10. The linkage member 11 is elastically movably connected to the linkage block 9. A time-delayed limiting component is provided on the base 1 to limit the movement of the linkage block 9. When the first tool holder 7 descends to the lowest position, the time-delayed limiting component cancels the limit. Specifically, the linkage rod 10 is axially horizontal and parallel to the direction of movement of the linkage block 9. The linkage rod 10 remains stationary under elastic force, but has a tendency to rotate after being subjected to force. A guide post is provided on the linkage member 11, axially parallel to the direction of movement of the linkage block 9. A guide hole matching the guide post is provided on the linkage block 9. A spring is also sleeved on the guide post and its two ends are connected to the linkage block 9 and the linkage member 11. Thus, the linkage member 11 also performs a threaded feed action when the linkage rod 10 rotates. The elastic connection between the positioning component and the linkage 11 and the linkage block 9 allows the linkage rod 10 to rotate during the descent of the first cutter holder 7. This causes the linkage 11 to move relative to the linkage block 9, initially resisting the elastic force. When the first cutter holder 7 descends to its lowest position, the delay limiting component cancels the limit, releasing the elastic force between the linkage 11 and the linkage block 9. The linkage block 9 moves relative to the linkage 11 to restore the distance between them. This triggers the two clamping wheels 4 to rotate, pulling the nylon tube a distance away from the cutter 3. Finally, during the retraction of the first cutter holder 7, if the delay limiting component does not reset and still cancels the limit on the linkage block 9, the rotation of the linkage rod 10 directly drives the linkage block 9 to slowly move back through the linkage 11. That is, the two clamping wheels 4 slowly rotate, gradually relaxing the nylon tube until the linkage block 9 resets, and the delay limiting component re-limits the linkage block 9.

[0037] As a preferred technical solution in this embodiment, one end of the linkage rod 10 is connected to the base 1 via a coil spring 12, and the other end is coaxially connected to a first trigger wheel 13. A first rack 14 matching the first trigger wheel 13 is provided on one side of the first cutter holder 7. Specifically, the coil spring 12 enables the linkage rod 10 to have an elastic rotation function, thereby enabling the linkage block 9 to automatically maintain its initial position through the linkage member 11. The initial position of the linkage block 9 is that the two clamping wheels 4 are clamped at the smallest radius and smooth position through the linkage gears 8 on both sides. The first cutter holder 7 drives the first rack 14 to descend, and the first rack 14 triggers the linkage rod 10 to rotate through the meshing transmission of the first trigger wheel 13. Similarly, when the first cutter holder 7 rises, the linkage rod 10 rotates in linkage.

[0038] As a preferred technical solution in this embodiment, the delay limiting component includes an undulating member 15 that is elastically and dynamically mounted on the base 1. The upper end of the undulating member 15 extends to the side wall of the first support 5 and is located within the lifting stroke of the first cutter holder 7. The lower end of the undulating member 15 extends to the lower side of the linkage block 9 and is fixedly mounted with a locking block 16. The bottom of the linkage block 9 is provided with a locking groove 17 that matches the locking block 16. Specifically, the undulating member 15 is vertically mounted on one side of the first support 5. Both the upper and lower ends of the undulating member 15 are bent toward the cutting table 2, thereby... The upper end of the undulating member 15 is in the lifting stroke of the first tool holder 7 and is located below the first tool holder 7. The lower end of the undulating member 15 is located below the linkage block 9, so that the locking block 16 and the locking groove 17 remain corresponding in the direction of movement of the linkage block 9. When the linkage block 9 is in the initial position, the locking block 16 and the locking groove 17 directly correspond and fit together. The undulating member 15 is connected to the base 1 by another spring, so that the undulating member 15 maintains the upward movement trend. Thus, when the locking block 16 and the locking groove 17 directly correspond, the locking block 16 remains embedded in the locking groove 17. In practical use, during the descent of the first cutter holder 7, the cutter 3 descends to cut the pipe, while the first rack 14 descends. As the rack 14 passes the first trigger wheel 13, it engages with the linkage rod 10, causing it to rotate. The linkage rod 10 and the linkage member 11 are fed by a thread, causing the linkage member 11 to move away from the cutter 3. At this time, the linkage block 9 is still limited by the locking block 16. The linkage member 11 moves relative to the linkage block 9, stretching the spring between them to store elastic potential energy. When the pipe cutting is completed and the first cutter holder 7 descends to its lowest position, the upper end of the undulating member 15 is pushed downwards, thus... The lower end of the undulating member 15 drives the locking block 16 to descend and leave the slot 17. As a result, the elastic tension between the linkage member 11 and the linkage block 9 is immediately released, and the linkage block 9 moves closer to the linkage member 11, that is, the linkage block 9 moves away from the cutter 3, so as to drive the two clamping wheels 4 to rotate, pulling the nylon tube between them away from the cutter 3 a certain distance. After that, the first cutter holder 7 rises, and according to the same principle, the two clamping wheels 4 rotate, so that the nylon tube slowly relaxes and moves closer to the cutter 3. After the linkage block 9 is reset, the locking block 16 and the slot 17 are aligned again, and the undulating member 15 moves up under the elastic force, thereby driving the locking block 16 to re-embed into the slot 17.

[0039] In another embodiment of the present invention, a punching platform 18 is provided on the base 1, and a punching knife 19 is provided above the punching platform 18. Specifically, a locator 20 is provided on the punching platform 18, and a guide sleeve 21 corresponding to the punching knife 19 is provided on the locator 20. The nylon tube passes through the locator 20 and then passes between the two clamping wheels 4. The locator 20 is hollow and is used to pass through the nylon tube. The guide sleeve 21 is axially vertical and has an opening at the upper end facing upward, which is vertically corresponding to the punching knife 19.

[0040] As a preferred technical solution in this embodiment, a second support 22 is fixedly provided on the base 1, and a second telescopic unit 23 is installed on the second support 22. The telescopic end of the second telescopic unit 23 is connected to the drilling knife 19 through the second knife holder 24. Specifically, the output end of the second telescopic unit 23 is vertically downward, and the second telescopic unit 23 is preferably a cylinder. The second knife holder 24 is slidably connected to a slide rail provided on the second support 22. The output end of the second telescopic unit 23 extends and retracts to drive the second knife holder 24 and the drilling knife 19 to move up and down.

[0041] As a preferred embodiment, a second rack 25 is fixedly mounted on one side of the second cutter holder 24, and a second trigger wheel 26 matching the second rack 25 is coaxially connected to the linkage rod 10. The first rack 14 and the second rack 25 are arranged on opposite sides of the linkage rod 10. Specifically, the locking block 16 can be movably mounted relative to the locking groove 17 along the direction of movement of the linkage block 9. In the initial position of the linkage block 9, the locking block 16 abuts against the end of the cutter 3 in the locking groove 17. When the second cutter holder 24 descends and drives the second rack 25 past the second trigger wheel 26, it triggers the meshing transmission, causing the linkage rod 10 to rotate. When the rotation direction is adjusted, the linkage 11 undergoes a helical drive and moves towards the cutter 3. At this time, the linkage 11 pushes the linkage block 9. Under the action of the spring between the linkage 11 and the linkage block 9, the linkage block 9 tends to move towards or towards the cutter 3. In addition, the locking block 16 moves in the locking groove 17. As a result, the two clamping wheels 4, in conjunction with the linkage block 9, pull the nylon tube between them away from the positioner 20, thereby further tightening the nylon tube portion passing through the positioner 20, which facilitates drilling. Similarly, when the second cutter holder 24 rises, the two clamping wheels 4 rotate to relax the nylon tube.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
