Description

Technical Field

[0001] This invention relates to the field of spiral corrugated pipe processing technology, and more specifically, to a spiral corrugated pipe cutting device. Background Technology

[0002] Spiral corrugated pipe is a type of pipe with a spiral corrugated structure, widely used in municipal and industrial fields. A common type is steel-reinforced polyethylene (HDPE) spiral corrugated pipe, which uses high-density polyethylene as the base material and corrugated steel strips coated with adhesive resin as reinforcement. The pipe wall structure typically includes an inner PE pipe, a steel strip reinforcement, and an outer PE layer. Some metal corrugated pipes are made of galvanized carbon steel coils, combining the high rigidity of steel with the corrosion resistance of plastic. The elastic modulus of steel is nearly 200 times that of polyethylene, achieving a balance between high performance and low cost. The internally reinforced type improves wave peak stability and enhances ring stiffness through vertical internal ribs. Due to its physical properties, spiral corrugated pipe is suitable for fluid transportation and protection in various complex environments. Small-diameter plastic spiral corrugated pipes (such as HDPE and PVC) are often used for wire and cable protection, possessing insulation, pressure resistance, and corrosion resistance.

[0003] In the automated processing of spiral corrugated pipes, cutting is a critical process. However, due to the periodic undulating corrugated structure on the outer wall of the spiral corrugated pipe, the rigid flat-end clamps of existing cutting equipment are unable to achieve uniform surface contact with the corrugated surface, resulting in insufficient clamping friction. Under the rotational impact force of the cutting workpiece, the pipe is prone to axial slippage and circumferential torsion, which seriously affects the flatness of the cut. In addition, since the position of the crest and trough of the pipe is random when it is fed in, traditional equipment uses a fixed stroke to cut. If the cutter is aligned with the trough, it is easy to cut too deeply and damage the inner pipe wall. If it is aligned with the crest, it is easy to fail to cut through.

[0004] In the existing technology, when cutting spiral corrugated pipes, traditional cutting equipment requires frequent equipment changes for different sizes of spiral corrugated pipes. At the same time, a large amount of manual operation and monitoring are required. This not only increases the labor intensity, but also makes it easy for human factors to cause operational errors, affecting the cutting quality and production safety. Summary of the Invention

[0013] Furthermore, the inner and outer sides of the machine body are provided with a discharge assembly, which includes a receiving cavity opened inside the machine body.

[0014] Furthermore, two guide rods are fixedly connected to the left and right sides inside the storage cavity. A first sleeve is slidably sleeved on the outer side of the guide rod.

[0017] Furthermore, a sliding groove is provided through the arc center of the extrusion strip on both sides, a sliding strip is slidably connected inside the sliding groove, a support strip is slidably connected inside the sliding groove, the opposite surfaces of the sliding strip and the support strip are fixedly connected, and columns are fixedly connected to the upper and lower sides of the extrusion strip that are far apart from each other. A second sleeve is fixedly connected to the upper and lower sides of the left end of the movable disc, and the second sleeve is sleeved on the outside of the column.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention provides basic clamping friction by setting an arc-shaped clamp with anti-slip texture. During the clamping process, the limiting rod will adaptively yield to different degrees according to the undulation of the corrugated pipe surface. The laser rangefinder can accurately capture the yield displacement and sense in real time whether the current cutting section is in the 'peak area' or 'valley area' of the pipe. The controller dynamically compensates the initial cutting coordinate of the cutting part accordingly. Since the anti-slip texture set on the arc surface of the clamp increases the friction between it and the spiral corrugated pipe, it prevents the spiral corrugated pipe from sliding during the subsequent cutting process, thus achieving initial fixation and positioning. At the same time, the laser rangefinder monitors the distance of the limiting rod movement in real time, so as to achieve the purpose of accurately controlling the position of the cutting part according to the size of the spiral corrugated pipe.

[0020] (2) The present invention adjusts the position of the movable block after being squeezed by the extrusion block by the pressure block and locks the movable block by the moving column. When the first magnetic block and the second magnetic block are close, the locking of the movable block is released. Since the pressure block is subjected to the pressure of the extrusion block, it will further compress the first pressure spring and the tension spring, so that the movable block is more stably fixed in the movable groove, thereby making the clamping block clamp the spiral corrugated pipe more firmly. At the same time, the movable plate will repeatedly realize the steps of clamping and releasing the spiral corrugated pipe during the reciprocating movement, making the cutting process of the spiral corrugated pipe smoother.

[0021] (3) In this invention, the first sleeve will slide outside the guide rod when the second electric push rod pushes the side plate. Before cutting, the initial position of the side plate and the second magnetic block can be adjusted by the second electric push rod to set the cutting length benchmark. During the cutting operation, the sliding of the first sleeve causes the first magnetic block to approach the adjusted second magnetic block, triggering the unlocking action, thereby ensuring that the batch cutting length is consistent. Since the spatial coordinates of the cutting parts are always fixed, changing the unlocking coordinate point changes the feeding length of the corrugated pipe when it stops, thereby achieving precise and consistent adjustment of the length of the subsequent batch cutting pipe segments. The cut spiral corrugated pipe segments will automatically fall into the receiving cavity due to gravity, thereby achieving the function of automatic unloading. Attached Figure Description

[0032] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8 A spiral corrugated pipe cutting device includes a machine body 1 and a conveyor box 11 fixedly connected to the upper left side of the machine body 1. A bracket 12 is fixedly connected to the middle of the upper end of the machine body 1. A first cylinder 13 is fixedly connected through the upper surface of the inner surface of the bracket 12. A cutting component 14 is provided at the telescopic end of the first cylinder 13. An adjustment component 2 is provided on the upper side of the machine body 1.

[0034] The adjusting component 2 includes a second cylinder 21 fixedly connected to the front and rear sides of the right end of the conveyor box 11. The telescopic end of the second cylinder 21 is fixedly connected to a movable plate 22. Movable grooves 23 are provided on both the upper and lower sides inside the movable plate 22. Movable blocks 24 are slidably connected inside the movable grooves 23. First electric push rods 25 are fixedly connected to the opposite faces of the upper and lower movable blocks 24. Clamping blocks 29 are fixedly connected to the telescopic end of the first electric push rods 25. First limiting grooves 26 are provided on both the front and rear sides inside the movable blocks 24. Limiting rods 27 are slidably connected inside the first limiting grooves 26. A laser rangefinder 28 is provided on the upper side of the interior of the first limiting groove 26 located at the rear upper part.

[0035] The opposing surfaces of the upper and lower clamping blocks 29 are arranged in an arc shape. The arc surface of the clamping blocks 29 is provided with anti-slip texture 3. The cutting part 14 is located on the upper left side of the movable disk 22. The movable block 24 is in the shape of an inverted "L". The first limiting groove 26 extends to the inner surface of the movable disk 22.

[0036] The upper side of the body 1 is provided with a clamping component 4.

[0037] By adopting the above technical solution, after the spiral corrugated pipe is conveyed out from the right side of the conveyor box 11, the second cylinder 21 at the right end of the conveyor box 11 is activated. The telescopic end of the second cylinder 21 drives the movable disc 22 to move towards the spiral corrugated pipe. As the movable disc 22 approaches the spiral corrugated pipe, the first electric push rod 25 is then activated to push the clamping block 29. When the movable disc 22 approaches the spiral corrugated pipe, the limiting rod 27 fixed to the clamping block 29 will slide inside the first limiting groove 26, causing the laser rangefinder 28 located on the upper side of the first limiting groove 26 to start working, measuring the moving distance of the limiting rod 27 in real time, and transmitting the information to the controller configured on the machine body 1. Because the opposing surfaces of the upper and lower clamping blocks 29 are arc-shaped and the arc surfaces are provided with anti-slip textures 3, they can better fit the spiral corrugated pipe. On the surface, as the second cylinder 21 continues to extend, the movable disc 22 will work with the clamping block 29 to pull the spiral corrugated pipe. When the second cylinder 21 begins to retract, it will work with the clamping component 4 to stop clamping the spiral corrugated pipe. When the second cylinder 21 retracts completely, the first cylinder 13 fixed by the bracket 12 starts to work and adjusts the position of the cutting piece 14 according to the information sent by the controller. Finally, the spiral corrugated pipe is cut by the cutting piece 14. Since the anti-slip texture 3 set on the arc surface of the clamping block 29 can increase its friction with the spiral corrugated pipe, it prevents the spiral corrugated pipe from sliding during the subsequent cutting process, thus achieving initial fixation and positioning. At the same time, the laser rangefinder 28 monitors the distance of movement of the limit rod 27 in real time, so as to achieve the purpose of accurately controlling the position of the cutting piece 14 according to the size of the spiral corrugated pipe.

[0038] like Figures 5 to 7 As shown, the clamping assembly 4 includes a plurality of first pressure springs 41 fixedly connected to the side of the movable block 24 away from the first electric push rod 25.

[0039] The other end of the first pressure spring 41 is fixedly connected to a pressure block 42, which is trapezoidal. Multiple tension springs 43 are fixedly connected between the other side of the pressure block 42 and the inner wall of the movable groove 23. The upper and lower sides of the left end of the movable disk 22 are provided with second limiting grooves 44. The horizontal part of the movable block 24 is slidably connected to the inside of the second limiting groove 44. The upper and lower sides of the left end of the movable disk 22 are provided with slots 45. The second limiting groove 44 is connected to the movable groove 23, and the slots 45 are connected to the movable groove 23. The upper and lower sides of the right end of the conveyor box 11 are fixedly connected with extrusion blocks 46. The extrusion blocks 46 are inserted into the inside of the slots 45. The right side of the extrusion blocks 46 is inclined. The inclined surface of the extrusion blocks 46 slides and presses against the inclined surface of the pressure block 42.

[0040] The right side of the interior of the movable slot 23 has a first groove 47, and the right side of the movable block 24 has a second groove 48. The interior of the first groove 47 and the second groove 48 are slidably connected to a movable column 49. The right end of the movable column 49 is fixedly connected to a first magnetic block 492. The upper right side of the body 1 is provided with a side plate 5. The front and rear sides of the left end of the side plate 5 are fixedly connected to second magnetic blocks 6. The first magnetic block 492 and the second magnetic block 6 are magnetically attracted to each other. After the movable column 49 moves, it completely enters the interior of the first groove 47. A second pressure spring 491 is fixedly connected between the movable column 49 and the right side of the interior of the first groove 47.

[0041] By adopting the above technical solution, when the extrusion block 46 passes through the slot 45 and enters the interior of the movable slot 23 and contacts the pressure block 42 inside the movable slot 23, the inclined surface of the extrusion block 46 will contact the inclined surface of the pressure block 42 and push the pressure block 42, causing the pressure block 42 to pull the tension spring 43. During this process, the pressure block 42 pushes the movable block 24 through the first pressure spring 41, but the movement trajectory of the movable block 24 is restricted by the second limiting slot 44. When the second groove 48 on the right side of the movable block 24 corresponds to the position of the first groove 47 on the inner side wall of the movable slot 23, the second pressure spring 491 inside the first groove 47 will push the moving column 49, causing part of the moving column 49 to slide from the first groove 47 into the second groove 48. At this time, the position of the movable block 24 will be locked, and it will lock the spiral bellows in conjunction with the clamping block 29. When the movable plate 22 moves to the right, the first fixed side plate 5 will be locked to the right. When the second magnetic block 6 approaches the first magnetic block 492, the attraction generated by the second magnetic block 6 will attract the first magnetic block 492 on the right side of the moving column 49, causing the moving column 49 to re-enter the first groove 47 from the second groove 48. At this time, the movable block 24, which is no longer limited by the moving column 49, slowly retracts into the movable groove 23 under the pull of the tension spring 43, making the clamping block 29 unable to clamp the spiral corrugated tube. If the second cylinder 21 retracts the movable plate 22, the spiral corrugated tube will remain in its original position until it is cut by the cutting part 14. As the pressure block 42 is subjected to the pressure of the squeezing block 46, it will further compress the first pressure spring 41 and the tension spring 43, making the movable block 24 more stably fixed in the movable groove 23, thereby making the clamping block 29 clamp the spiral corrugated tube more firmly. At the same time, the movable plate 22 will repeatedly perform the steps of clamping and releasing the spiral corrugated tube during the reciprocating movement, making the cutting process of the spiral corrugated tube smoother.

[0042] like Figure 1 and Figure 2 As shown, the inner and outer sides of the body 1 are provided with unloading assembly 7, and the unloading assembly 7 includes a storage cavity 71 opened inside the body 1.

[0043] Two guide rods 72 are fixedly connected to the left and right sides inside the storage cavity 71. A first sleeve 73 is slidably sleeved on the outer side of the guide rod 72. The first sleeve 73 is fixedly connected to the lower side of the side plate 5. A fixing block 74 is fixedly connected to the center of the lower side of the side plate 5. A second electric push rod 75 is fixedly connected to the right side inside the body 1. The telescopic end of the second electric push rod 75 is fixedly connected to the right side of the fixing block 74. The left and upper sides of the storage cavity 71 are connected to the outside. A ramp is provided on the right side inside the storage cavity 71.

[0044] By adopting the above technical solution, before cutting the spiral corrugated pipe, the second electric push rod 75 can be activated according to the cutting length of the spiral corrugated pipe, so that the telescopic end of the second electric push rod 75 drives the fixed block 74 to move left and right. Since the center of the lower side of the side plate 5 is fixed to the fixed block 74, and the first sleeve 73 on the lower side of the side plate 5 is slidably sleeved on the outside of the guide rod 72, and since the unlocking action is triggered entirely by the spatial distance between the first magnetic block 492 and the second magnetic block 6, before the cutting begins, the operator adjusts the initial lateral position of the side plate and the second magnetic block 6 fixed on it by activating the second electric push rod 75, which essentially sets the position. The "spatial unlocking coordinate point" is defined when the movable disc 22 pulls the spiral corrugated pipe to the right. When the movable disc 22 pulls the spiral corrugated pipe to the right and reaches this coordinate point, the clamping component 4 instantly unlocks and releases the spiral corrugated pipe. The spiral corrugated pipe will stop at the current position due to the loss of inertia and friction, waiting for cutting. Since the spatial coordinates of the cutting part are always fixed, changing the unlocking coordinate point changes the feeding length of the corrugated pipe when it stops, thereby achieving precise and consistent adjustment of the length of the subsequent batch of cut pipe segments. The cut spiral corrugated pipe segments will automatically fall into the receiving cavity 71 due to gravity, thereby achieving the function of automatic unloading.

[0045] like Figures 1 to 4 As shown, the inner and outer sides of the conveyor box 11 are provided with a material guiding assembly 8, which includes an embedded groove 81 on the upper and lower sides inside the conveyor box 11.

[0046] An extrusion strip 82 is slidably connected inside the embedding groove 81. The opposing surfaces of the upper and lower extrusion strips 82 are arc-shaped. Multiple balls 83 are slidably connected to the arc surface of the extrusion strip 82. Multiple third pressure springs 84 are fixedly connected between the other side of the extrusion strip 82 and the inner wall of the embedding groove 81.

[0047] A groove 85 is provided through the arc center of the extrusion strip 82. A slide bar 86 is slidably connected inside the groove 85. A support bar 87 is slidably connected inside the groove 85. The opposite surfaces of the slide bar 86 and the support bar 87 are fixedly connected. A column 89 is fixedly connected to the side of the extrusion strip 82 on both the upper and lower sides. A second sleeve 88 is fixedly connected to both the upper and lower sides of the left end of the movable plate 22. The second sleeve 88 is sleeved on the outside of the column 89.

[0048] By adopting the above technical solution, when the spiral corrugated pipe is conveyed from the conveyor box 11, it enters the embedding groove 81 area opened on the upper and lower sides inside the conveyor box 11. The extrusion strip 82, which is slidably connected inside the embedding groove 81, can tightly fit the surface of the spiral corrugated pipe under the action of the third pressure spring 84 and the arc-shaped ball bearings 83 of the extrusion strip 82. As the spiral corrugated pipe is conveyed, the extrusion strip 82 automatically adjusts its position according to the size of the spiral corrugated pipe under the elastic force of the third pressure spring 84. When the movable disc 22 moves, the second sleeve 88 fixed on the upper and lower sides of the left end of the movable disc 22 is engaged. Located outside the column 89 where the extrusion bar 82 is fixed, the support bar 87 moves along with the movable disc 22 as the movable disc 22 begins to move, supporting the spiral corrugated pipe. After the spiral corrugated pipe is cut, it rolls down from above the support bar 87. Since the ball bearings 83 always maintain good contact with the spiral corrugated pipe, the friction between the spiral corrugated pipe and the extrusion bar 82 is reduced, allowing the spiral corrugated pipe to be transported more smoothly. At the same time, the support bar 87 moves synchronously with the spiral corrugated pipe and supports it, ensuring the stability of the spiral corrugated pipe.

[0049] Working principle: In the adjusting component 2, the telescopic end of the second cylinder 21 at the right end of the conveyor box 11 drives the movable disc 22 to move. The first electric push rod 25 pushes the clamping block 29. The laser rangefinder 28 measures the moving distance of the limit rod 27 to precisely control the position of the cutting part 14. In the clamping assembly 4, the inclined surface of the extrusion block 46 contacts and pushes the inclined surface of the pressure block 42 to lock the position of the movable block 24. This, together with the clamping block 29, locks the spiral bellows. The second magnetic block 6 attracts the first magnetic block 492, causing the moving column 49 to re-enter the first groove 47. The movable block 24 retracts. When the tube enters the movable slot 23, the clamping block 29 is released, achieving stable clamping and smooth reciprocating cutting during cutting. In terms of the unloading component 7, the second electric push rod 75 drives the side plate 5 to move, and the position of the second magnetic block 6 is adjusted to ensure consistent cutting length. The cut tube segment slides down the slope of the receiving cavity 71 for collection, achieving automatic unloading. In the guiding component 8, the extrusion strip 82 adheres to the spiral corrugated tube under the action of the third pressure spring 84, and the ball bearing 83 reduces friction. When the movable disc 22 moves, the support strip 87 supports the spiral corrugated tube, ensuring smooth conveying and stability during cutting.
