Description

Technical Field

[0001] This invention relates to the technical field of corrugated pipe processing, and in particular to a corrugated pipe cutting machine tool. Background Technology

[0002] Corrugated pipes are pipes with a regular wavy shape and multiple equidistant peaks on their outer wall, with a trough between adjacent peaks. Due to their unique structure, they are widely used for pipe connections in various fields. Existing technologies disclose various corrugated pipe cutting devices, such as the corrugated pipe cutting machine and its traction mechanism proposed in Chinese invention patent CN109732685B. This cutting machine includes a working platform; a sliding assembly, including a sliding seat and a guide rail mounted on the working platform, the sliding seat cooperating with the guide rail; a drive assembly, located on the working platform and connected to the sliding seat; and a clamping assembly. The clamping assembly clamps and transports the corrugated pipe, replacing the existing friction-based transport method, reducing slippage during transport, improving stability, and enhancing the precision control of the corrugated pipe cutting length.

[0003] Because corrugated pipes have a certain degree of elasticity, during the transport of corrugated pipes, due to frictional resistance or traction force, the corrugated pipes are often in an elongated or compressed state when cut. The aforementioned pipe cutting equipment does not eliminate the aforementioned elongated or compressed state of the corrugated pipes during the pipe cutting process. After the pipes are cut directly, the dimensions of the cut corrugated pipes will have a large deviation after they naturally return to their original position. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a corrugated pipe cutting machine tool that eliminates the elongation or compression state of the corrugated pipe before cutting, thereby reducing the dimensional deviation of the cut corrugated pipe and improving the cutting accuracy.

[0005] This invention discloses a corrugated pipe cutting machine tool, comprising a frame, a feeding conveyor assembly, and a discharging conveyor assembly. The feeding conveyor assembly is installed at the front of the frame, and the discharging conveyor assembly is installed at the rear of the frame. The feeding and discharging conveyor assemblies are used to transport corrugated pipes. It also includes a gantry, a cutting mechanism, a clamping assembly, and a spacing adjustment mechanism. The gantry is installed between the feeding and discharging conveyor assemblies, and the cutting mechanism is installed on the gantry. The cutting mechanism is used to cut the corrugated pipes between the feeding and discharging conveyor assemblies. The clamping assembly is installed in the middle of the frame and is used to clamp the corrugated pipes. The clamping assembly is located on both the front and rear sides of the cutting mechanism. The spacing adjustment mechanism is movably installed at the rear of the frame and is used to adjust the corrugation spacing of the corrugated pipes located on the discharging conveyor assembly to achieve the designed corrugation spacing. During operation, the corrugated pipes are placed on the feeding conveyor assembly, and the feeding and discharging conveyor assemblies operate synchronously to cut the corrugated pipes. The corrugated tube is conveyed to the rear of the frame. When the length of the corrugated tube extending beyond the cutting mechanism approaches the specified length, the conveying stops. The clamping assembly clamps the portion of the corrugated tube located between the feeding and unloading conveying assemblies. The pitch adjustment mechanism moves from the cutting mechanism to the rear of the frame. During the movement, the pitch adjustment mechanism measures the corrugation spacing of the corrugated tube one by one, unfolds the compressed corrugations, and compresses the stretched corrugations, so that the corrugation spacing of the corrugated tube on the unloading conveying assembly reaches the design value. At this time, this part of the corrugated tube is in its natural state. The positions of the gantry and the cutting mechanism are precisely adjusted so that the length of the corrugated tube behind the cutting mechanism reaches the specified length. The cutting mechanism runs and cuts the corrugated tube, and the cut corrugated tube is removed. Compared with the existing technology, this method eliminates the corrugation elongation or compression state of the corrugated tube during the conveying process before cutting, reduces the dimensional deviation after the cut corrugated tube naturally returns to its original position, and improves the cutting accuracy.

[0006] Preferably, the pitch adjustment mechanism includes a slide rail, a slide table, a lifting platform, a vertical push cylinder, a fixed clamping mold, a movable clamping mold, and a horizontal push cylinder. The slide rail is installed at the rear of the frame and is parallel to the material feeding and conveying assembly. The slide table is movably slidably installed on the slide rail. The lifting platform is vertically slidably installed on the slide table. The two ends of the vertical push cylinder are respectively connected to the slide table and the lifting platform. The fixed clamping mold is installed on the front of the lifting platform, and the movable clamping mold is slidably installed on the rear of the lifting platform. The two ends of the horizontal push cylinder are respectively connected to the lifting platform and the movable clamping mold. The slide table moves backward along the slide rail. When the slide table stops, the corrugation pitch of the corrugated pipe above it is measured. If the corrugation pitch is not up to standard... At this time, the piston rod of the vertical push cylinder extends, pushing the lifting platform, the fixed clamping mold, and the moving clamping mold upward, so that the fixed clamping mold and the moving clamping mold respectively clamp the crest or trough of two adjacent corrugations. The horizontal push cylinder extends or retracts the piston rod according to the measurement data, thereby adjusting the distance between the moving clamping mold and the fixed clamping mold, thereby adjusting the distance between the two crests or two troughs, and thus adjusting the corrugation spacing. The piston rod of the vertical push cylinder retracts, causing the lifting platform to descend, and the fixed clamping mold and the moving clamping mold to disengage from the bellows. The above actions are repeated to gradually adjust the corrugation spacing of the bellows backward, thereby eliminating the elongation or compression state of the bellows.

[0007] Preferably, it also includes a rack, a geared motor, and a gear. The rack is mounted on the rear of the frame and is parallel to the slide rail. The geared motor is mounted on the slide table, and the output shaft of the geared motor is concentrically mounted with a gear that meshes with the rack. The geared motor drives the gear to rotate, and the gear meshes with the rack to drive the slide table to move along the slide rail. The drive is stable and the technology is mature.

[0008] Preferably, it also includes a measuring device, installed on the lifting platform, to measure the corrugation spacing of the corrugated pipe; the measuring device is preferably a non-contact measuring instrument such as a laser rangefinder, a vision measurement system, a photo measurement system, or a lidar; when using a photo measurement system, the number of pixels between two peaks or two troughs in the captured image can be compared with the number of pixels in a standard image. If the number of pixels is too high, the corrugation spacing is too large, and if the number of pixels is too low, the corrugation spacing is too small; this achieves efficient measurement of the corrugation spacing without friction with the corrugated pipe.

[0009] Preferably, the feeding and conveying assembly includes conveyor belt one and conveyor belt two, which are respectively installed on the left and right sides of the front of the frame, and are arranged in a V-shape. The corrugated pipe is placed on the opposite surfaces of conveyor belt one and conveyor belt two. The V-shaped conveyor belt one and conveyor belt two support and limit the corrugated pipe. Conveyor belt one and conveyor belt two run synchronously to convey the corrugated pipe backward, integrating the conveying and limiting functions of the corrugated pipe, simplifying the structure. In order to improve the conveying quality, conveyor belt one and conveyor belt two adopt chain plate conveyor belts.

[0010] Preferably, the unloading conveying assembly includes conveyor belt three, conveyor belt four, and a tilting drive. Conveyor belt three is obliquely installed on the left side of the rear of the frame, and is parallel and aligned with conveyor belt one. The lower part of conveyor belt four is hinged to the right side of the rear of the frame, and is parallel and aligned with conveyor belt two. The tilting drive is installed on the frame and drives conveyor belt four to tilt. The tilting drive can be a geared motor, hydraulic motor, hydraulic cylinder, or other drive structure. During the conveying and cutting of the corrugated pipe, the tilting drive drives conveyor belt four to be parallel and aligned with conveyor belt two. After the corrugated pipe is cut, the tilting drive drives conveyor belt four to tilt to the right side of the rear of the frame, so that the cut corrugated pipe rolls out of the frame along conveyor belt four, completing the unloading.

[0011] Preferably, it also includes a damper, one end of which is connected to the frame and the other end of which is connected to the conveyor belt four. By setting the damper, the conveyor belt four is buffered during the overturning process, making the overturning of the conveyor belt four more stable and avoiding the danger caused by the accidental rolling of the cut corrugated pipe.

[0012] Preferably, the cutting mechanism includes two pipe-cutting motors, two drive wheels, a wire saw, two screws, a transmission assembly, and a lifting motor. The two pipe-cutting motors are slidably mounted on the left and right columns of the gantry, respectively. The output shafts of the two pipe-cutting motors are concentrically mounted on the drive wheels. The wire saw is mounted on the two drive wheels. The two screws are rotatably mounted on the left and right columns of the gantry, respectively, and are threadedly connected to the two pipe-cutting motors. The two screws are connected via the transmission assembly. The lifting motor is mounted on the gantry, and its output shaft is connected to the screws. The lifting motor drives one screw to rotate, and the other screw rotates synchronously through the transmission assembly. The rotation of the two screws drives the two pipe-cutting motors to move synchronously up and down along the left and right columns of the gantry through the threads. During the movement of the two pipe-cutting motors, the two pipe-cutting motors drive the wire saw to rotate through the two drive wheels, enabling the wire saw to automatically cut the corrugated pipe, which is highly practical.

[0013] Preferably, the cutting mechanism includes two slides, two driven wheels, a lifting assembly, an upper frame, a second pipe-cutting motor, a second drive wheel, a second wire saw, and a balancer. The two slides are slidably mounted on the left and right columns of the gantry, respectively. The two driven wheels are rotatably mounted on the two slides, respectively. The lifting assembly is mounted on the gantry and drives the two slides to rise and fall synchronously. The upper frame is mounted on the upper part of the gantry. The second pipe-cutting motor is slidably mounted on the upper frame. The output shaft of the second pipe-cutting motor is concentrically mounted on the second drive wheel. The second wire saw is mounted on the two driven wheels and the second drive wheel. The balancer is mounted on... Mounted on the upper frame, the balancer's cable is connected to the second pipe-cutting motor. The balancer elastically winds up the cable, suspending the second pipe-cutting motor and the second drive wheel. This causes the second drive wheel to tension the second wire saw. The second pipe-cutting motor drives the second drive wheel to rotate, which in turn drives the second wire saw to rotate. The lifting assembly drives the two slides to rise and fall synchronously, allowing the second wire saw between the two driven wheels to cut the corrugated pipe. This prevents the second wire saw, located above the two driven wheels, from entering the cut seam of the corrugated pipe and causing secondary cutting at the cut, thus improving the cutting quality of the cut.

[0014] Preferably, the clamping assembly includes multiple clamping cylinders, multiple pressure plates, and multiple sponge suction cups. The multiple clamping cylinders are respectively mounted on the gantry and the frame. Pressure plates are mounted on the piston rod ends of each of the multiple clamping cylinders, and sponge suction cups are mounted on the pressure plates, all facing the corrugated pipe. After the loading and unloading conveying assemblies support and limit the lower part of the corrugated pipe, the piston rods of the multiple clamping cylinders extend, pushing the multiple pressure plates and multiple sponge suction cups towards the upper part of the corrugated pipe, causing the multiple sponge suction cups to engage with the corrugated pipe. The outer wall of the bellows is pressed tightly against the surface. Multiple sponge suction cups are connected to an external air extraction system. The air extraction system extracts air from the multiple sponge suction cups, causing them to adhere to the upper outer wall of the bellows. This results in the bellows being held in place by the clamping pressure of multiple pressure plates and sponge suction cups. When the bellows is cut from top to bottom, it is subjected to the pressure of the cutting mechanism. At this time, the suction force of the multiple sponge suction cups cancels out the pressure of the cutting mechanism, preventing excessive deformation of the bellows during cutting and improving the cutting accuracy.

[0015] Compared with the prior art, the beneficial effects of the present invention are: after eliminating the corrugated elongation or compression state of the corrugated pipe caused during the corrugated pipe transportation process, the pipe is cut, which reduces the dimensional deviation of the cut corrugated pipe after natural reset and improves the pipe cutting accuracy.

[0027] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Example 1

[0028] like Figures 1 to 4 , Figure 7 and Figure 10As shown, a corrugated pipe cutting machine includes a frame 1, a feeding conveyor assembly 2, and a discharging conveyor assembly 3. The feeding conveyor assembly 2 is installed at the front of the frame 1, and the discharging conveyor assembly 3 is installed at the rear of the frame 1. The feeding conveyor assembly 2 and the discharging conveyor assembly 3 are used to convey corrugated pipes. It also includes a gantry 4, a cutting mechanism 5, a clamping assembly 6, and an adjusting mechanism 7. The gantry 4 is installed between the feeding conveyor assembly 2 and the discharging conveyor assembly 3, and the cutting mechanism 5 is installed on the gantry 4. The cutting mechanism 5 is used to cut the corrugated pipes between the feeding conveyor assembly 2 and the discharging conveyor assembly 3. The pipe cutting and clamping assembly 6 is installed in the middle of the frame 1. The clamping assembly 6 is used to clamp the corrugated pipe and is located on the front and rear sides of the cutting mechanism 5. The pitch adjustment mechanism 7 is movably installed at the rear of the frame 1. The pitch adjustment mechanism 7 is used to adjust the corrugation spacing of the corrugated pipe located on the unloading conveying assembly 3 so that the corrugation spacing of the corrugated pipe reaches the design value. The pitch adjustment mechanism 7 includes a slide rail 8, a slide table 9, a lifting platform 10, a vertical push cylinder 11, a fixed clamping mold 12, a movable clamping mold 13, and a horizontal push cylinder 14. The slide rail 8 is installed at the rear of the frame 1 and is connected to the unloading conveying assembly 3. The feeding component 3 is parallel to the slide table 9, which is movably slidably mounted on the slide rail 8. The lifting platform 10 is vertically slidably mounted on the slide table 9. The two ends of the vertical push cylinder 11 are respectively connected to the slide table 9 and the lifting platform 10. The fixed clamping mold 12 is mounted on the front of the lifting platform 10, and the movable clamping mold 13 is slidably mounted on the rear of the lifting platform 10. The two ends of the horizontal push cylinder 14 are respectively connected to the lifting platform 10 and the movable clamping mold 13. The machine also includes a rack 15, a reduction motor 16, and a gear 17. The rack 15 is mounted on the rear of the frame 1 and is parallel to the slide rail 8. The reduction motor 16 is mounted on... On the slide table 9, a gear 17 is concentrically mounted on the output shaft of the geared motor 16, and the gear 17 meshes with the rack 15; it also includes a measuring device 18, which is mounted on the lifting platform 10, and measures the corrugation spacing of the bellows through the measuring device 18; the clamping assembly 6 includes multiple pressing cylinders 39, multiple pressure plates 40 and multiple sponge suction cups 41, the multiple pressing cylinders 39 are respectively mounted on the gantry 4 and the frame 1, pressure plates 40 are mounted on the piston rod ends of the multiple pressing cylinders 39, and sponge suction cups 41 are mounted on the multiple pressure plates 40, and the multiple sponge suction cups 41 are all facing the bellows.

[0029] 8. Prefer non-contact measuring instruments such as laser rangefinders, visual measurement systems, photo measurement systems, and lidar. When using a photo measurement system, the number of pixels between two peaks or two troughs in the captured image can be compared with the number of pixels in the standard image. If the number of pixels is too high, the ripple spacing will be too large; if the number of pixels is too low, the ripple spacing will be too small.

[0030] During operation, the corrugated pipe is placed on the feeding conveyor assembly 2. The feeding conveyor assembly 2 and the unloading conveyor assembly 3 operate synchronously to convey the corrugated pipe to the rear of the frame 1. When the length of the corrugated pipe extending beyond the cutting mechanism 5 approaches the specified length, the conveying stops. The piston rods of multiple pressing cylinders 39 extend, pushing multiple pressure plates 40 and multiple sponge suction cups 41 towards the upper part of the corrugated pipe, so that the multiple sponge suction cups 41 contact and press against the outer wall of the corrugated pipe. The multiple sponge suction cups 41 are connected to an external air extraction system, which extracts air from the multiple sponge suction cups 41, causing the multiple sponge suction cups 41 to press against the upper part of the corrugated pipe. The bellows is held in place by the wall suction, which applies a certain clamping pressure from multiple pressure plates 40 and multiple sponge suction cups 41. The reduction motor 16 drives the gear 17 to rotate, and the gear 17 meshes with the rack 15 to drive the slide table 9 to move backward along the slide rail 8. When the slide table 9 is paused, the measuring device 18 measures the corrugation spacing of the bellows above it. When the corrugation spacing is not up to standard, the piston rod of the vertical push cylinder 11 extends, pushing the lifting platform 10, the fixed clamping mold 12, and the moving clamping mold 13 upward, so that the fixed clamping mold 12 and the moving clamping mold 13 respectively clamp the crest or trough of two adjacent corrugations, and push horizontally. Cylinder 14 extends or retracts the piston rod according to the measurement data, thereby adjusting the distance between the moving clamping mold 13 and the fixed clamping mold 12, thereby adjusting the distance between the two peaks or two troughs, and thus adjusting the corrugation spacing. The piston rod of the vertical push cylinder 11 retracts, causing the lifting platform 10 to descend, and the fixed clamping mold 12 and the moving clamping mold 13 to disengage from the bellows. The above actions are repeated to gradually adjust the corrugation spacing of the bellows backward, thereby eliminating the elongation or compression state of the bellows, so that the corrugation spacing of the bellows on the feeding conveying assembly 3 all reaches the design value. At this time, this part of the bellows is in a natural state. The positions of the gantry 4 and the cutting mechanism 5 are precisely adjusted so that the length of the corrugated pipe at the rear of the cutting mechanism 5 reaches the specified length. The cutting mechanism 5 then cuts the corrugated pipe from top to bottom. The corrugated pipe is subjected to the pressure of the cutting mechanism 5. At this time, the adsorption force of multiple sponge suction cups 41 cancels out the pressure of the cutting mechanism 5, preventing the corrugated pipe from being excessively deformed during the cutting process and improving the cutting accuracy. The cut corrugated pipe is then removed. Compared with the existing technology, this method eliminates the corrugated elongation or compression state of the corrugated pipe caused during the corrugated pipe transportation process before cutting, reducing the dimensional deviation of the cut corrugated pipe after natural reset and improving the cutting accuracy. Example 2

[0031] like Figures 1 to 6As shown, based on Embodiment 1, the feeding conveyor assembly 2 includes a first conveyor belt 19 and a second conveyor belt 20, which are respectively installed on the left and right sides of the front part of the frame 1, and are arranged in a V-shape; the unloading conveyor assembly 3 includes a third conveyor belt 21, a fourth conveyor belt 22 and a tilting drive 23, the third conveyor belt 21 is installed obliquely on the left side of the rear part of the frame 1, and is parallel and aligned with the first conveyor belt 19, the lower part of the fourth conveyor belt 22 is hinged to the right side of the rear part of the frame 1, and is parallel and aligned with the second conveyor belt 20, the tilting drive 23 is installed on the frame 1, and the tilting drive 23 drives the fourth conveyor belt 22 to tilt; it also includes a damper 24, one end of which is connected to the frame 1, and the other end of which is connected to the fourth conveyor belt 22.

[0032] The corrugated pipe is placed on the opposite surfaces of conveyor belt 19 and conveyor belt 20. The V-shaped arrangement of conveyor belts 19 and 20 supports and limits the corrugated pipe. Conveyor belts 19 and 20 operate synchronously to transport the corrugated pipe backward, integrating the functions of conveying and limiting the corrugated pipe, simplifying the structure. To improve the conveying quality, conveyor belts 19 and 20 use chain conveyor belts. The tilting drive 23 can be a geared motor, hydraulic motor, hydraulic cylinder, or other drive structure. During the conveying and cutting of the corrugated pipe, the tilting drive 23 drives conveyor belt 42 to align parallel to conveyor belt 20. After the corrugated pipe is cut, the tilting drive 23 drives conveyor belt 422 to tilt to the right rear of the frame 1, so that the cut corrugated pipe rolls out of the frame 1 along conveyor belt 42, completing the unloading. By setting a damper 24 to buffer the tilting process of conveyor belt 422, the tilting of conveyor belt 422 is made smoother, avoiding the danger caused by the accidental rolling of the cut corrugated pipe. Example 3

[0033] like Figure 2 and Figure 8 As shown, based on Embodiment 1, the cutting mechanism 5 includes two pipe-cutting motors 25, two drive wheels 26, a wire saw 27, two screws 28, a transmission assembly 29, and a lifting motor 30. The two pipe-cutting motors 25 are slidably mounted on the left and right columns of the gantry 4, respectively. The output shafts of the two pipe-cutting motors 25 are concentrically mounted on the drive wheels 26. The wire saw 27 is fitted onto the two drive wheels 26. The two screws 28 are rotatably mounted on the left and right columns of the gantry 4, respectively. The two screws 28 are threadedly connected to the two pipe-cutting motors 25, respectively. The two screws 28 are connected by transmission through the transmission assembly 29. The lifting motor 30 is mounted on the gantry 4, and the output shaft of the lifting motor 30 is connected by transmission to the screws 28.

[0034] The lifting motor 30 drives one screw 28 to rotate. One screw 28 drives another screw 28 to rotate synchronously through the transmission assembly 29. The rotation of the two screws 28 drives two pipe cutting motors 25 to move synchronously along the left and right columns of the gantry 4 through the threads. During the movement of the two pipe cutting motors 25, the two pipe cutting motors 25 drive the wire saw 27 to rotate through the two drive wheels 26 respectively, so that the wire saw 27 can automatically cut the corrugated pipe, which is practical.

[0035] Example 4, as Figure 9 As shown, based on Embodiment 1, the cutting mechanism 5 includes two slides 31, two driven wheels 32, a lifting assembly 33, an upper frame 34, a second pipe-cutting motor 35, a second drive wheel 36, a second wire saw 37, and a balancer 38. The two slides 31 are slidably mounted on the left and right columns of the gantry 4, respectively. The two driven wheels 32 are rotatably mounted on the two slides 31, respectively. The lifting assembly 33 is mounted on the gantry 4 and drives the two slides 31 to lift synchronously. The upper frame 34 is mounted on the upper part of the gantry 4. The second pipe-cutting motor 35 is slidably mounted on the upper frame 34. The output shaft of the second pipe-cutting motor 35 is concentrically mounted on the second drive wheel 36. The second wire saw 37 is fitted on the two driven wheels 32 and the second drive wheel 36. The balancer 38 is mounted on the upper frame 34, and the cable of the balancer 38 is connected to the second pipe-cutting motor 35.

[0036] The balancer 38 elastically retracts the cable, suspending the pipe-cutting motor 35 and the drive wheel 36. The drive wheel 36 then tensions the wire saw 37. The pipe-cutting motor 35 drives the drive wheel 36 to rotate, which in turn drives the wire saw 37 to rotate. The lifting assembly 33 drives the two slides 31 to rise and fall synchronously, allowing the wire saw 37 between the two driven wheels 32 to cut the corrugated pipe. This prevents the wire saw 37 located above the two driven wheels 32 from entering the cutting seam of the corrugated pipe and causing secondary cutting at the cut, thus improving the cutting quality of the cut.

[0037] like Figures 1 to 10As shown, in the present invention, a corrugated pipe cutting machine tool is operated as follows: First, the corrugated pipe is placed on the feeding conveyor assembly 2. The feeding conveyor assembly 2 and the unloading conveyor assembly 3 operate synchronously to convey the corrugated pipe to the rear of the frame 1. When the length of the corrugated pipe extending beyond the cutting mechanism 5 approaches the specified length, the conveying stops. Then, the piston rods of multiple pressing cylinders 39 extend, pushing multiple pressure plates 40 and multiple sponge suction cups 41 towards the upper part of the corrugated pipe, so that the multiple sponge suction cups 41 contact and press against the outer wall of the corrugated pipe. The multiple sponge suction cups 41 are connected to an external air extraction system, which evacuates the multiple sponge suction cups 41, causing the multiple sponge suction cups 41 to adhere to the upper outer wall of the portion of the corrugated pipe located between the feeding conveyor assembly 2 and the unloading conveyor assembly 3. The pitch adjustment mechanism 7 moves from the cutting mechanism 5 to the rear of the frame 1. During the movement, the measuring device 18 measures the corrugation spacing of the corrugated pipe one by one. The fixed clamping mold 12 and the moving clamping mold 13 work together to unfold the compressed corrugations of the corrugated pipe and compress the stretched corrugations, so that the corrugation spacing of the corrugated pipe on the feeding conveyor assembly 3 reaches the design value. At this time, this part of the corrugated pipe is in a natural state. The positions of the gantry 4 and the cutting mechanism 5 are precisely adjusted so that the length of the corrugated pipe behind the cutting mechanism 5 reaches the specified length. The cutting mechanism 5 runs to cut the corrugated pipe. Finally, the flipping drive 23 drives the conveyor belt 4 22 to flip to the right rear of the frame 1, so that the cut corrugated pipe rolls out of the frame 1 along the conveyor belt 4 22, and the feeding is completed.

[0038] The main functions achieved by this invention are:

[0039] 1. After eliminating the elongation or compression of the bellows, cut the pipe to reduce the dimensional deviation of the cut bellows and improve the cutting accuracy.

[0040] 2. The V-shaped feeding conveyor assembly 2 and unloading conveyor assembly 3 support, limit, and convey the corrugated pipe, integrating the conveying and limiting functions of the corrugated pipe, simplifying the structure, and improving the conveying quality.

[0041] 3. After the corrugated pipe is cut, the flipping drive 23 drives the conveyor belt 4 22 to flip to the right rear of the frame 1, so that the cut corrugated pipe rolls out of the frame 1 along the conveyor belt 4 22, completing the unloading.

[0042] 4. When the corrugated pipe is cut from top to bottom, the corrugated pipe is subjected to the pressure of the cutting mechanism 5. At this time, the adsorption force of multiple sponge suction cups 41 is offset by the pressure of the cutting mechanism 5, which avoids excessive deformation of the corrugated pipe during cutting and improves the cutting accuracy.

[0043] The present invention discloses a corrugated pipe cutting machine tool. Its installation, connection, or setting methods are all common mechanical methods; any method that achieves the desired beneficial effect can be implemented. The corrugated pipe cutting machine tool of the present invention comprises: a frame 1, a feeding conveyor assembly 2, a discharging conveyor assembly 3, a gantry 4, a cutting mechanism 5, a clamping assembly 6, a slide rail 8, a slide table 9, a fixed clamping mold 12, a moving clamping mold 13, a horizontal push cylinder 14, a vertical push cylinder 11, a rack 15, a reduction motor 16, a gear 17, a measuring device 18, a first conveyor belt 19, a second conveyor belt 20, and a third conveyor belt 21. 1.
