Abstract

This invention relates to the field of metal cutting technology and discloses an intelligent pipe cutting machine and its cutting method. In order to solve the problem that waste material is easily thrown out after the oblique cutting operation of the end of the round pipe, a drill bit is vertically arranged on one side of the cutting support. The bottom of the drill bit is lower than the outer bottom of the cutting blade. When the cutting blade performs oblique cutting on the end of the round pipe, the rotating drill bit will first drill a hole in the waste material. Then, the drill bit can limit the waste material after drilling. After the cutting blade finishes cutting the end of the round pipe, the drill bit limits the waste material to prevent it from flying out, and finally achieves the effect of limiting the drilling of waste material.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal cutting, and particularly relates to an intelligent pipe cutting machine and a pipe cutting method thereof. BACKGROUND

[0002] Pipe cutting machines, as a kind of mechanical equipment specially used for cutting pipes, play a crucial role in modern industrial production. With its high-efficiency and precise cutting performance, it is widely used in various fields, including mechanical manufacturing, construction engineering, pipe installation, automobile manufacturing, and electronic equipment manufacturing. In the field of mechanical manufacturing, pipe cutting machines can quickly and accurately cut pipes of various specifications to meet the production needs of different parts. For example, in sewage sedimentation and sand removal applications, bevel cutting honeycomb pipes play a unique role. During actual installation, bevel cutting honeycomb pipes are usually installed at an angle of 60°. This special installation method can significantly shorten the distance of particle sedimentation, allowing particles in the sewage to settle down more quickly. This bevel cutting honeycomb pipe is widely used in domestic sewage plants, chemical plant wastewater treatment, and other scenarios, enabling rapid sedimentation of sewage.

[0003] However, there are some problems in the current bevel cutting operation of round pipes that need to be solved. Usually, the operator will use a clamping assembly to clamp the round pipe, and make the end of the pipe to be cut in a suspended state. This operation method has certain advantages. On the one hand, it can effectively avoid the accumulation of cutting chips on the table. If the cutting chips accumulate on the table, the cutting chips may be cut again by the cutter during the subsequent cutting process, causing secondary cutting, damaging the cutter and reducing the service life of the cutter. On the other hand, this suspended state can also avoid direct contact between the round pipe and the table. Because when the round pipe directly contacts the table, the cutter may be disturbed by the table during cutting, causing the saw blade or cutter to break, affecting the cutting quality and safety of the cutter.

[0004] However, this cutting method also brings new problems. Because the end of the pipe is relatively suspended during cutting, the cutting residue of the pipe will fly outwards, which not only poses a threat to the safety of the operator, but also may cause damage to surrounding equipment and the environment. For example, if the cutting residue hits the operator, it may cause injury. In addition, the flying cutting residue may also damage the surrounding equipment and the environment, causing safety hazards and economic losses. Figure 7For example, when the end of the round pipe is beveled by 45 degrees, the remaining material after cutting is relatively small during the beveling process. This makes it difficult to clamp and secure the remaining material after cutting is completed. Because the remaining material is small, the clamping assembly cannot find a suitable clamping point and cannot provide sufficient clamping force to secure the remaining material. On the other hand, when beveling, the force exerted by the cutting tool on the pipe is not perpendicular to the surface of the pipe, but a lateral component is generated. When the waste material is gradually cut off during the cutting process, a certain amount of elastic strain energy is accumulated inside the pipe. When the waste material is completely cut off, the accumulated elastic strain energy is suddenly released, and under the action of the lateral component, the waste material may be ejected in the direction of the cutting force, resulting in the problem of workpiece flying out. SUMMARY

[0005] The present application provides an intelligent pipe cutting machine and a pipe cutting method thereof, which has a waste material drilling limiting function. This function can effectively solve the problem of waste material flying out after the end of the round pipe is beveled.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an intelligent pipe cutting machine, comprising: a base, the surface of which is provided with clamping assemblies on both sides for limiting the round pipe, and a steering chassis assembly movably installed in the middle; a vertical movement assembly, the bottom of which is fixed to the steering chassis assembly, for driving an externally installed cutting support to move up and down; a cutting motor, installed on the cutting support, with a cutting blade for cutting the round pipe fixedly installed on the side of the output shaft, and a driving bevel gear fixedly installed on the end of the output shaft; a drill rod holder, movably installed on the side of the cutting support by a support, with a driven bevel gear fixedly installed on the outside for meshing transmission with the driving bevel gear, and a drill bit for drilling the waste material of the round pipe installed at the bottom; when the round pipe is beveled, the cutting support descends by the vertical movement assembly, and the drill bit drills the round pipe first; after the cutting blade completes the beveling of the round pipe, the drill bit inserted into the drilled hole can limit the movement of the cut waste material to prevent it from flying out.

[0007] Further, a return spring is arranged between the middle of the drill rod holder and the support.

[0008] Further, when the waste material of the round pipe cutting does not need to be reserved, the cutting motor drives the cutting blade and the drill bit to rotate first, the cutting support descends according to the control of the vertical movement assembly, the drill bit limits the waste material by drilling first, and then the cutting blade cuts the round pipe; when the waste material of the round pipe cutting needs to be reserved, the vertical movement assembly drives the cutting support to descend first, the drill bit reaches the outside of the round pipe and the driven bevel gear and the driving bevel gear are disengaged; then, when the cutting motor drives the cutting blade to cut the round pipe, the drill bit does not drill the waste material of the round pipe; after cutting is completed, the drill bit is pushed by the elastic force of the return spring, which tends to push the waste material to move downward quickly, thereby reducing the risk of the waste material flying out.

[0009] Further, the top disc is coaxially and tightly fixed on the side of the cutting piece, and a plurality of arc-shaped top blocks are arranged on the side of the top disc at equal angles in the circumferential direction, an adjusting rod is movably arranged on the side of the cutting support, and the arc-shaped top blocks are used to realize the extension of the adjusting rod from the side of the cutting support when the top disc rotates.

[0010] Further, a guide frame is arranged on the inner side of the cutting support and is guided by a round rod, the end of the guide frame is fixedly connected with the side of the adjusting rod, and a return spring is arranged between the guide frame and the cutting support and located on the outer side of the round rod; a pressing arm is movably arranged on the bottom of the guide frame, a limit spring is arranged between the pressing arm and the guide frame, and a press ruler is tightly arranged on the bottom of the pressing arm.

[0011] Further, the return spring is used to drive the guide frame to retract the adjusting rod into the cutting support, the cutting support is arranged on the side of the top disc and located between the arc-shaped top blocks, and the side of the press ruler is aligned with the side of the cutting piece at this time.

[0012] A pipe cutting method of an intelligent pipe cutting machine, comprising the following steps:

[0013] S1, the clamping assembly clamps and fastens the circular pipe, so that the end of the circular pipe to be cut is in a suspended state.

[0014] S2, the turning chassis assembly is used to rotate, so as to adjust the actual cutting angle of the cutting piece and make the circular pipe below the drill bit be the waste part after cutting.

[0015] S3, the cutting support is lowered according to the vertical movement assembly, and in this process, the cutting motor drives the cutting piece and the drill bit to rotate synchronously.

[0016] S4, in the process that the cutting support drives the drill bit to descend, the drill bit firstly contacts the circular pipe to drill the waste material, and as the cutting piece and the drill bit continuously descend, the drill bit is inserted into the drill hole of the waste material to limit the position of the waste material.

[0017] S5, when the cutting piece completely cuts the end of the circular pipe, the drill bit is used to limit the circular pipe to prevent the waste material from flying out.

[0018] The intelligent pipe cutting machine and the pipe cutting method thereof have the following beneficial effects:

[0019] The intelligent pipe cutting machine and the pipe cutting method thereof have the following beneficial effects:

[0020] After the drill bit completes drilling into the scrap material, it effectively limits the drilled scrap. As the cutting blade continues to work, once it has completely cut the end of the round tube, the scrap material initially tends to fly outwards due to the force exerted by the tool on the tube and the potential elastic deformation of the scrap itself. However, the drill bit's restraint on the scrap material effectively prevents this from happening.

[0021] Ultimately, through this structural design and operational process, the present invention achieves a significant effect in limiting waste material during drilling. This effect improves the safety of pipe cutting operations, preventing potential injury to operators from flying waste and damage to surrounding equipment and the environment.

[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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figure 1 As can be seen, the platform 1 described in this application utilizes the pre-drilled mounting holes at the four corners to securely restrain it in the desired position. Clamping components 5 are arranged on both sides of the platform 1. These clamping components 5 are mainly used to suspend and clamp the round tube, thereby ensuring that the cutting position of the round tube is relatively suspended, preventing damage to the cutting tool due to chip accumulation on the platform during cutting. Figure 1 In the middle, the clamping assembly 5 includes fixed / movable arc-shaped clamping blocks. The movable arc-shaped clamping block is adjusted by a lead screw. The rotation of the lead screw allows the two clamping blocks to move closer / away, ultimately achieving clamping and limiting of the circular tube. For the lead screw drive method in this application, a handwheel or servo motor can be used for control; the appropriate method can be selected according to the specific requirements. Since there are two clamping assemblies 5, when cutting the middle of the circular tube, both clamping assemblies 5 can clamp and limit the circular tube, ensuring that both cut circular tubes are effectively limited. If a bevel cut is required at the end of the circular tube, only one clamping assembly 5 is needed to limit the tube's position.

[0034] A steering chassis assembly 2 is movably mounted on the center of the surface of the base 1 via bearings. The steering chassis assembly 2 can rotate within the center of the surface of the base 1. By rotating the steering chassis assembly 2, the cutting angle of the cutting blade 7 can be changed, thereby adjusting the bevel cutting angle at the end of the round tube. After the steering chassis assembly 2 is adjusted, according to... Figure 1 It can be seen that by using the fastening bolts set on the outer side of the steering chassis assembly 2 to lock it, the steering chassis assembly 2 cannot be rotated, ensuring that the steering chassis assembly 2 will not rotate freely due to external factors after adjustment.

[0035] Regarding the installation and driving of the cutting disc 7, according to Figure 1 and Figure 2It can be seen that the vertical motion component 3 mounted on the outer side of the steering chassis assembly 2 can control the up-and-down movement of the cutting support 4. Specifically, the vertical motion component 3 consists of a vertical guide rail, a slider, a lead screw, and a servo motor. The cutting support 4 is fixedly connected to the slider. The servo motor controls the rotation of the lead screw, which drives the slider to move up and down along the vertical guide rail, thus achieving the vertical reciprocating motion of the cutting support 4. Figure 2 and Figure 3 It can be seen that a cutting motor 6 is bolted to the side of the cutting support 4, and a cutting blade 7 located inside the cutting support 4 is fixedly mounted on the output shaft side of the cutting motor 6. When the cutting motor 6 drives the cutting blade 7 to rotate, the round tube is cut according to the cutting blade 7. Furthermore, a drive bevel gear 12 located outside the cutting support 4 is fixedly mounted at the end of the output shaft of the cutting motor 6. Correspondingly, a drill rod frame 9 is movably mounted on the side of the cutting support 4 via the support. A driven bevel gear 120 meshing with the drive bevel gear 12 is fixedly mounted on the outer side of the drill rod frame 9. When the cutting motor 6 drives the cutting blade 7 to rotate, the drill rod frame 9 rotates synchronously according to the transmission of the drive bevel gear 12 and the driven bevel gear 120. Moreover, from... Figure 3 and Figure 4 It can be clearly seen that the drill bit 10 is detachably installed at the bottom of the drill rod holder 9. The bottom of the drill bit 10 is lower than the outer bottom of the cutting disc 7. The advantage of this design is that when the cutting support 4 is close to the round pipe, the drill bit 10 can contact the round pipe first, before the cutting disc 7.

[0036] In practical applications, when it is necessary to bevel the end of a round tube, a clamping assembly 5 is used to clamp and secure the round tube, keeping the end of the tube to be cut suspended in the air. Then, the steering chassis assembly 2 is rotated to adjust the actual cutting angle of the cutting blade 7, so that the part of the round tube below the drill bit 10 becomes the waste material after cutting.

[0037] Subsequently, the vertical motion component 3 drives the cutting support 4 to descend. During this process, the cutting motor 6 drives the cutting blade 7 and the drill bit 10 to rotate synchronously. Since the drill bit 10 will contact the round tube first, when the cutting support 4 drives the drill bit 10 to descend, the drill bit 10 drills a hole in the round tube waste. As the cutting blade 7 and the drill bit 10 continue to descend, the drill bit 10 will eventually insert into the hole in the waste, thus restricting the position of the waste. After the cutting blade 7 completely cuts off the end of the round tube, the drill bit 10 is used to limit the round tube, preventing the waste from flying out.

[0038] Example 2 is a further improvement on Example 1. Since the drill bit 10 always rotates synchronously with the cutting disc 7, when the cutting disc 7 cuts waste material at the middle of the round tube or needs to retain the end of the round tube, the drilling by the drill bit 10 will result in a round hole in the cut waste material, making it unusable. This Example 2 aims to achieve on-demand control of the rotation of the drill bit 10, combined with… Figure 2 and Figure 3 It can be seen that a return spring 11 is provided between the middle of the drill rod frame 9 and the support. Under normal conditions, the drill rod frame 9 is pushed by the elastic force of the return spring 11 to drive the driven bevel gear 120 downward, and realize the meshing between the driving bevel gear 12 and the driven bevel gear 120. Therefore, when the waste does not need to be retained, the cutting motor 6 drives the cutting blade 7 and the drill bit 10 to rotate first, and controls the cutting support 4 to move downward according to the vertical motion component 3, so that the drill bit 10 first drills and limits the waste, and realizes the drilling limit mentioned in Embodiment 1. If the waste needs to be retained, the vertical motion component 3 needs to drive the cutting support 4 downward first. With the cutting support 4 pressing down, the drill bit 10 first reaches the outside of the round tube. During this process, the drill bit 10 is blocked by the round tube and cannot move. As the cutting support 4 continues to move downward, the drill rod frame 9 will compress the return spring 11 and disengage the driven bevel gear 120 and the driving bevel gear 12. At this time, the drill bit 10 will not rotate with the cutting motor 6. Finally, the round tube is cut by the cutting blade 7, and as the cutting support 4 continues to descend, the round tube is completely severed. In this method, because the cutting support 4 drives the cutting blade 7 to continuously descend and cut the round tube, the downward movement of the cutting support 4 causes the return spring 11 to be continuously compressed and store force. After the cutting blade 7 cuts the round tube, its drill bit 10 still rests against the scrap, but at this time, the drill bit 10 is pushed by the elastic force of the return spring 11, forcing it to tend to push the scrap rapidly downward. Figure 1 As can be seen, the platform of the steering chassis assembly 2 is located below the cutting disc 7. When the drill bit 10 pushes the waste material down rapidly, the waste material will eventually descend rapidly and contact the platform of the steering chassis assembly 2, thereby reducing the risk of waste material flying out.

[0039] Based on the above, further supplement, combined with Figure 3 , Figure 5 and Figure 6 It can be seen that the cutting blade 7 has a top plate 16 coaxially fastened to its side with bolts, and multiple arc-shaped top blocks 160 are arranged at equal angles around the side of the top plate 16. The arc-shaped top blocks 160 are higher in the middle and lower at both ends, with an arc-shaped transition between the middle and the ends. Correspondingly, an adjusting rod 14 is movably installed on the side of the cutting support 4. When the cutting blade 7 drives the top plate 16 to rotate, the arc-shaped top blocks 160 push the adjusting rod 14, forcing it to tend to extend from the side of the cutting support 4. Simultaneously, from... Figure 3As can be seen, the drill rod holder 9 has a locking disc 13 mounted on the side using bearings and located above the driven bevel gear 120. Under normal conditions, the drill rod holder 9 is pushed downward by the return spring 11, causing the driven bevel gear 120 and the driving bevel gear 12 to mesh. At this time, the driven bevel gear 120 is located below the adjusting rod 14. If the waste material is no longer needed, the cutting motor 6 drives the cutting blade 7 and the drill bit 10 to rotate. When the cutting blade 7 drives the top plate 16 to rotate, the arc-shaped top block 160 will abut against the adjusting rod 14 and move the end of the adjusting rod 14 above the locking disc 13. Afterward, when the cutting support 4 drives the drill bit 10 and the cutting blade 7 downward, the adjusting rod 14 blocks the locking disc 13, thus preventing the drill bit 10 from moving upward and ensuring that the drill bit 10 has sufficient strength to contact the waste material. Similarly, when the waste material can be reused, the cutting support 4 drives the cutting blade 7 and the drill bit 10 to move downwards first, and the drill bit 10 pushes the driven bevel gear 120 and the locking disc 13 to move upwards synchronously and compress the return spring 11 until the locking disc 13 is above the adjusting rod 14. Then, when the cutting blade 7 drives the top plate 16 to rotate, the arc-shaped top block 160 pushes the adjusting rod 14 outwards again, which will place the adjusting rod 14 below the locking disc 13. This ensures that during the cutting process, the locking disc 13 is blocked by the adjusting rod 14 and cannot move downwards normally, ensuring that the driven bevel gear 120 and the driving bevel gear 12 cannot mesh, and the drill bit 10 will also be unable to rotate.

[0040] It should be noted that in practical applications, the locking disc 13 has an angled or frustum-shaped slope on its side. This design ensures that when the adjusting rod 14 abuts against the outer side of the locking disc 13, the slope of the adjusting rod 14 can drive the locking disc 13 to move up and down, preventing the locking disc 13 from blocking the adjusting rod 14 from extending outward and causing a jam between the adjusting rod 14 and the arc-shaped top block 160. Furthermore, to prevent such problems, the diameter of the locking disc 13 is larger than the top diameter of the driven bevel gear 120, ensuring that when the adjusting rod 14 extends, it can be positioned above / below the locking disc 13, but the adjusting rod 14 will not contact the driven bevel gear 120, thus preventing the driven bevel gear 120 from restricting the extension of the adjusting rod 14.

[0041] Moreover, reference Figures 3-5 It can be seen that the inner side of the cutting support 4 has a guide frame 15 installed using a round rod for guidance. The guide frame 15 is L-shaped, and its end is fixedly connected to the side of the adjusting rod 14. From Figure 5 As can be seen, a return spring 150 located on the outer side of the round rod is installed between the guide frame 15 and the cutting support 4. The guide frame 15 is pushed by the elastic force of the return spring 150, so that the guide frame 15 always tends to pull the adjusting rod 14 back into the cutting support 4, which also makes the adjusting rod 14 always tend to move towards the top plate 16.

[0042] A pressure arm 17 is movably mounted at the bottom of the guide frame 15, and the pressure arm 17 can only reciprocate up and down along the guide frame 15. A limiting spring 170 is installed between the pressure arm 17 and the guide frame 15. Under normal conditions, the limiting spring 170 pushes the pressure arm 17 downward to its bottom limit. A pressure gauge 8 is bolted to the bottom of the pressure arm 17, and the angle between the pressure gauge 8 and the pressure arm 17 is within 10°-75°. The advantage of this design is that, according to… Figure 4 It can be seen that under normal conditions, the pressure gauge 8 is lower than the bottom of the drill bit 10, and is pushed by the return spring 150, causing the adjusting rod 14 to retract into the cutting support 4. The cutting support 4 abuts against the side of the top plate 16 and is located between the arc-shaped top blocks 160. At this time, the length of the adjusting rod 14 retracted into the cutting support 4 is at its maximum, and the side of the pressure gauge 8 is also aligned with the side of the cutting disc 7. When it is necessary to bevel the end of the round pipe, the cutting support 4 moves downward and the pressure gauge 8 is placed against the top of the round pipe. At this time, the position of the side of the pressure gauge 8 is the cutting part. The pressure gauge 8 can be used to accurately know the cutting part of the round pipe, which makes it easier for the operator to adjust the round pipe and ensure the accuracy of the cutting position.

[0043] The first cutting method involves using the cutting blade 7 to make a bevel cut on the end of the round tube. If the waste material from cutting the round tube is not needed, the cutting motor 6 starts first during cutting. During this process, the cutting motor 6 drives the drill bit 10 to rotate through the drive bevel gear 12 and the driven bevel gear 120. At the same time, the cutting blade 7 rotates synchronously and drives the top plate 16 to rotate. When the top plate 16 drives the arc-shaped top block 160 past the adjusting rod 14, the arc-shaped top block 160 pushes the adjusting rod 14 outward and positions it above the locking plate 13. At this time, the adjusting rod 14 synchronously drives the guide frame 15 to move and presses the return spring 150. Initially, after the adjusting rod 14 passes the arc-shaped top block 160, it is pushed by the elastic force of the return spring 150, causing the guide frame 15 to drive the adjusting rod 14 back to the top plate 16. However, as the cutting support 4 continues to descend, the pressure gauge 8 further compresses the waste material about to be cut at the end of the round tube, causing the pressure arm 17 to compress the limiting spring 170. This results in increased contact force between the pressure gauge 8 and the waste material, i.e., increased friction. When the arc-shaped top block 160 pushes the adjusting rod 14 outward again, the friction between the pressure gauge 8 and the waste material overcomes the return spring 150, pushing the guide frame 15 to reset. This ensures that the adjusting rod 14 is always pushed outward and positioned above the locking disc 13.

[0044] As the cutting support 4 descends, the drill bit 10 contacts the waste material and limits its drilling. Next, the cutting support 4 drives the cutting blade 7 downwards, using it to make a bevel cut on the end of the round tube. After the cutting blade 7 has finished cutting the end of the round tube, the waste material, pushed by the limiting spring 170, is dislodged from the drill bit 10 by the downward push of the pressure gauge 8, and further away from the cutting blade 7 as the pressure gauge 8 pushes it. This completes the drilling and limiting cutting of the useless waste material.

[0045] In the second cutting method, when using the cutting blade 7 to make a bevel cut on the end of the round tube, if it is necessary to retain the scrap material after cutting, the cutting motor 6 needs to stop working before the cutting begins, and the pressure gauge 8 should first press the round tube according to the cutting support 4. Afterwards, as the drill bit 10 contacts the scrap material, it is blocked by the scrap material, causing the driven bevel gear 120 on the drill rod holder 9 to disengage from the driving bevel gear 12, until the locking disc 13 moves above the adjusting rod 14.

[0046] Then, the cutting motor 6 is started. At this time, when the top plate 16 is rotated by the cutting blade 7, the end of the adjusting rod 14 will move to below the locking plate 13. The adjusting rod 14 limits the downward movement of the locking plate 13 to prevent the drill rod holder 9 from accidentally descending. Afterward, as the cutting support 4 descends, the cutting blade 7 can cut the round pipe, and the drill bit 10 pushes the drill rod holder 9, which will further compress the return spring 11 and the pressure arm 17 will further compress the limiting push spring 170.

[0047] from Figure 4 As can be seen, because the pressure gauge 8 is arranged obliquely upwards while the drill bit 10 is arranged vertically downwards, when both the drill bit 10 and the pressure gauge 8 reach the outside of the waste material as they descend, the angled area formed by the drill bit 10 and the pressure gauge 8 further increases the positional constraint on the waste material. This positional constraint will occur after the cutting blade 7 completely cuts the round tube, as the pressure arm 17 and the drill bit 10 are pushed downwards by the limiting spring 170 and the return spring 11, respectively. At this time, the angled area formed by the two will also tend to push the waste material downwards. Therefore, it is easy to see that the drill bit 10 and the pressure gauge 8 can, on the one hand, limit the position of the waste material, and on the other hand, by simultaneously applying downward pushing force to the cut waste material, the risk of the cut waste material flying outwards is reduced.
