Description

Technical Field

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

[0002] A corrugated pipe is a type of pipe with a corrugated shape that can expand and contract axially and bend to accommodate displacement and deformation. It is often used to protect cables, compensate for thermal expansion and contraction of pipes, and transport fluids.

[0003] In existing technologies, plastic corrugated pipes are widely used. However, these corrugated pipes generally have a significant problem: they are prone to collapse. The structural characteristics of plastic corrugated pipes make them susceptible to loss of original support under external pressure, long-term pressure, or complex environments such as temperature changes, leading to collapse. Once the corrugated pipe collapses, its original regular shape and structure are destroyed, the pipe wall becomes uneven and severely deformed in some areas. This will cause great inconvenience to subsequent cutting operations, making it difficult to ensure a smooth cut, damaging the cutting tools, affecting cutting efficiency and quality, and increasing production costs and operational difficulty. To address this, we propose a cutting device for corrugated pipes. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] A corrugated pipe cutting device includes a base 1, and further includes: columns 2 and a processing unit 4. Two sets of columns 2 are fixedly connected to the top of the base 1. A cutting unit 3 is arranged between the two columns 2. The cutting unit 3 includes a receiving plate 31 and a cutting wheel 352. The cutting wheel 352 is arranged at the bottom of the receiving plate 31. The receiving plate 31 drives the cutting wheel 352 to move and rotate to adjust the cutting position. The processing unit 4 is arranged at the top of the base 1. The processing unit 4 includes a hydraulic rod 42, a second motor 441 and a ball shaft 447. The hydraulic rod 42 and the second motor 441 drive the ball shaft 447 to move and rotate to handle the collapse of the corrugated pipe.

[0025] The cutting unit 3 includes a support plate 31 disposed between two sets of columns 2. A first motor 32 is fixedly connected to the bottom of the support plate 31. A chain 33 is engaged at the drive end of the first motor 32. A rotating shaft 34 is rotatably connected to the bottom of the support plate 31. One end of the chain 33 is engaged with the outside of the rotating shaft 34. By setting up the first motor 32, the chain 33 and the rotating shaft 34, the first motor 32 drives the chain 33 to rotate, thereby driving the rotating shaft 34 to rotate, and then driving the cutting piece 35 to rotate. This allows the corrugated pipe to be cut at different angles.

[0026] A cutting component 35 is provided at the bottom of the rotating shaft 34 for cutting the bellows; the cutting component 35 includes a power box 351 fixedly connected to the bottom of the rotating shaft 34, a cutting wheel 352 is provided outside the power box 351, and a prior art drive structure is provided inside the power box 351 for driving the cutting wheel 352 to rotate. The structure inside the power box 351 is prior art and will not be described in detail here.

[0027] The processing unit 4 includes a first frame 41 fixedly connected to the top of the base 1. A hydraulic rod 42 is fixedly connected to the outer end of the first frame 41. The driving end of the hydraulic rod 42 extends into the first frame 41 and is fixedly connected to a moving block 43. A processing component 44 is provided on the top of the moving block 43 for processing the collapse of the bellows. The hydraulic rod 42 can drive the processing component 44 to move back and forth, which facilitates the restoration of multiple collapsed positions in the bellows.

[0028] The processing component 44 includes a second motor 441 fixedly connected to the top of the moving block 43. The drive end of the second motor 441 is fixedly connected to a drive rod 442. The drive rod 442 passes through the first frame 41 and is fixedly connected to a connecting plate 443. A sliding sleeve 444 is fixedly connected to the outside of the connecting plate 443. A sliding rod 445 is slidably connected inside the sliding sleeve 444. A connecting block 446 is fixedly connected to the outer end of the sliding rod 445. A ball shaft 447 is rotatably fitted inside the connecting block 446. A damping rod 448 is fixedly connected to the outside of the connecting plate 443. One end of the damping rod 448 is fixedly connected to the sliding rod 445. A spring 449 is sleeved on the damping rod 448. The spring 449 provides elastic force to achieve rapid reset, while the damping rod 448 consumes energy to suppress vibration and slow down the movement speed. The combination of the two can take into account both buffering and reset functions.

[0029] In use, a section of corrugated pipe is fitted over multiple ball shafts 447, and the corrugated pipe is clamped and fixed. Then, the hydraulic rod 42 is activated to push the processing component 44 to the specific location where the corrugated pipe has collapsed. Then, the second motor 441 is activated, which drives the drive rod 442 to rotate, thereby causing the multiple ball shafts 447 to revolve. The multiple ball shafts 447 contact the inner wall of the corrugated pipe. At the same time, they compress the spring 449 and the damping rod 448. The spring 449 rebounds and can press against the inner wall of the corrugated pipe. In this way, the ball shafts 447 rotate inside the corrugated pipe, which can restore the collapsed position. Then, the first motor 32 is activated, which drives the chain 33 to rotate, which drives the rotating shaft 34 and the cutting component 35 to rotate, rotating the cutting wheel 352 to the cutting position. Then, the existing drive structure in the power box 351 is activated to drive the cutting wheel 352 to rotate and cut the corrugated pipe. Example 2

[0030] Please see Figure 1 and Figure 5 This utility model provides a technical solution:

[0031] Unlike Embodiment 1, both sets of columns 2 are slidably connected to the inner sides of lifting plates 5, both sets of columns 2 are fixedly connected to the inner sides of outer plates 6, both sets of outer plates 6 are fixedly connected to the top of hydraulic cylinders 7, the driving ends of the two sets of hydraulic cylinders 7 are fixedly connected to the two lifting plates 5 respectively, a third motor 8 is fixedly connected to the outer side of one lifting plate 5, the driving end of the third motor 8 is fixedly connected to a first lead screw 9, the first lead screw 9 passes through the receiving plate 31 and is threadedly engaged with it, and multiple limiting rods 10 are fixedly connected between the two lifting plates 5, and the multiple limiting rods 10 all pass through the receiving plate 31 and are slidably connected with it;

[0032] Start two sets of hydraulic cylinders 7, which drive two lifting plates 5 to rise and fall synchronously. This drives the cutting wheel 352 to rise and fall for cutting. Start the third motor 8, which drives the first lead screw 9 to rotate. This causes the receiving plate 31 to move horizontally under the limiting support of multiple limit rods 10. In short, the cutting position can be adjusted.

[0033] Two second frames 11 are fixedly fitted into the top of the base 1. A second lead screw 12 is rotatably connected inside each of the two second frames 11. The outer ends of the two second lead screws 12 pass through the second frames 11 and the base 1 and are fixedly connected to a rotating wheel 13. A clamp 14 is slidably arranged inside each of the two second frames 11. The bottom of the two clamps 14 is threadedly engaged with the two second lead screws 12 respectively.

[0034] Rotating the two rotating wheels 13 drives the two second lead screws 12 to rotate, thereby driving the two clamps 14 to move under the limit of the two second frames 11. The relative movement of the two clamps 14 can clamp and fix the bellows.
