Description

Technical Field

[0001] This invention belongs to the field of cable protection pipe production technology, specifically referring to a cable protection pipe production cutting device. Background Technology

[0002] Cable protection pipes are conduits used for laying cables, typically made of materials such as PVC, PE, or metal. Their main function is to provide mechanical and insulation protection for cables, preventing external damage such as corrosion and compression, through pre-embedding or direct laying in power and communication line projects. They are crucial infrastructure for ensuring the safe operation of these lines. During the production process, cable protection pipes need to be cut to achieve the required length. During this cutting, burrs and flash will appear at both ends, requiring grinding to prevent scratching the cable insulation layer during subsequent use.

[0003] In related technologies, the grinding of the cut edges of cable protection pipes usually involves first cutting the cable protection pipes in a centralized manner, and then transporting them to a grinding workshop for unified grinding. The grinding method mostly uses manual hand-held grinding tools to grind the cut edges of the cable protection pipes. This processing method has low production efficiency, cannot achieve synchronous cutting and grinding, requires a high level of manual labor, and is labor-intensive. Summary of the Invention

The output end of the upper grinding machine is connected to an upper grinding disc, and the upper grinding machine is bolted to the upper surface of the upper movable base.

[0014] Furthermore, the lower grinding assembly is located below the first cylindrical cam.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1. The pipe fitting switching assembly is rotatably mounted on the processing table and, together with the centering clamping assembly on its surface, can automatically center and clamp the pipe fitting to be cut. The rotating motor drives the symmetrically arranged rotating tables to rotate 180 degrees, so that the pipe fitting located at the upper station, after being cut and ground at one end, can be automatically switched to the lower station for grinding at the other end. This effectively realizes the integration and automated continuous production of cutting and double-end grinding processes, significantly improving production efficiency.

[0018] 2. To ensure that the rotating table does not interfere with the grinding components on both sides when it rotates the pipe 180 degrees, the first and second cylindrical cams located at both ends of the drive shaft, through the curved grooves opened on their surfaces, cooperate with the upper and lower drive rollers in the upper and lower grinding components. Before rotating, they can drive the grinding components to move to both sides to effectively avoid interference, and after rotating, they can drive them to accurately reset. This linkage mechanism ensures the reliability and smoothness of complex actions and avoids the risk of equipment collision.

[0019] 3. The drive motor connected to one side of the first clamping member drives the inner roller to rotate, thereby causing the pipe fixed by the centering clamping assembly to rotate at a uniform speed. While cooperating with the cutting machine on the cutting table to perform cutting operations, the cut end of the pipe is made to rotate relative to the grinding disc of the upper or lower grinding machine, realizing the synchronous operation of pipe cutting and circumferential grinding. This not only ensures the coaxiality and uniformity of the cut surface and the grinding surface, but also greatly saves the processing time of a single piece.

[0020] 4. The upper and lower grinding components work in conjunction with the pipe fitting switching assembly. The lower grinding component is equipped with a buffer guide rod and a buffer spring, which allows the lower grinding machine and its top displacement slider to float elastically within a certain range. This allows it to adapt to the pipe fitting end face and provide flexible and constant grinding pressure, avoiding over-grinding or uneven grinding. This ensures high quality and consistency of grinding results at both ends. At the same time, the full-process automation greatly reduces the intensity of manual labor and skill dependence.

[0046] In one embodiment of the present invention, a rotating support part 59 is provided at the top of one end of the support platform 58. The rotating support part 59 is rotatably connected to the drive shaft 15 on the side of the first cylindrical cam 12. A receiving box 5 is inclinedly provided below the processing table 1. One end of the receiving box 5 is hinged to the other end of the support platform 58.

[0047] Working principle: When using the cable protection pipe production and cutting device of the present invention for processing, the operator first guides the long pipe into the turning table 11 through the guide plate 7 of the guide roller feeding area 6, and makes its end abut against the upper grinding disc 37 on the upper grinding machine 36. Subsequently, the clamping cylinder 29 in the clamping drive assembly 17 is activated, which drives the toothed plates 31 on both sides to move through the drive member 30, and the transmission gear 26 is engaged to rotate; the transmission gear 26 drives the first clamping member 22 and the second clamping member 24 to move towards each other along the displacement guide rail 34 through the top drive plate 27 and the connecting rod 28, and clamps the pipe in the center through the multiple rollers 25 on its clamping surface.

[0048] It should be noted that relevant personnel can also set a longer limiting plate 18 on the turning table 11 so that the limiting plate 18 and the upper grinding disc 37 are on the same horizontal plane. This helps to prevent the end of the pipe to be processed from being misaligned with the upper grinding disc 37.

[0049] After clamping is completed, the drive motor 23 on one side of the first clamping member 22 starts, driving the roller 25 connected to it to rotate, thereby causing the clamped pipe to rotate at a constant speed. At this time, the lifting motor 9 on the top of the cutting table 8 starts, driving the cutting machine 10 to descend and cut the rotating pipe. At the same time, the upper grinding assembly 20 located at the front end of the pipe is in the forward position driven by the curved groove 35 of the second cylindrical cam 13, and the upper grinding machine 36 drives the upper grinding disc 37 to rotate, performing synchronous circumferential grinding on the cut end face of the rotating pipe.

[0050] After cutting and one-end grinding are completed, the tilting motor 19 starts, driving the drive shaft 15 and the first cylindrical cam 12 and the second cylindrical cam 13 coaxially fixed thereon to rotate. Before the tilting table 11 begins to tilt, the curved grooves 35 on the two cams first drive the upper drive roller 44 and the lower drive roller 53 that cooperate with them, respectively driving the upper grinding assembly 20 and the lower grinding assembly 21 to move to both sides along the upper moving guide rod 39 and the lower moving guide rod 46, fully clearing the tilting space. Subsequently, the tilting motor 19 drives the tilting table 11, which is symmetrically arranged on both sides, to complete a 180-degree tilt, transferring the processed pipe to the lower position, while making the upper position available for newly introduced pipes.

[0051] It should be noted that the curved groove 35 can realize a reset cycle of the upper drive roller 44 and the lower drive roller 53 moving back and forth every 180 degrees.

[0052] After the flipping action is completed, the two cylindrical cams continue to rotate, and their curved grooves 35 drive the upper and lower grinding components to reset. The unprocessed end of the lower pipe is now facing the lower grinding component 21, and the lower grinding machine 47 drives the lower grinding disc 48 to grind its end face. During this process, the displacement slider 50 at the top of the lower grinding machine 47 can compress the buffer spring 55 along the buffer guide rod 56, providing flexible and constant grinding pressure to adapt to the pipe end face and ensure grinding quality. After grinding is completed, the centering clamping component 16 is released, and the processed pipe falls into the receiving box 5 under gravity, thus completing the fully automated processing of a single pipe.

[0053] In summary, the cable protection pipe production and cutting device of the present invention features a pipe switching assembly rotatably mounted on a processing table, which, in conjunction with a centering clamping assembly on its surface, automatically centers and clamps the pipe to be cut. A rotating motor drives a symmetrically arranged rotating table to rotate 180 degrees, allowing the pipe at the upper station to automatically switch to the lower station for grinding the other end after cutting and grinding at one end. This effectively integrates the cutting and double-end grinding processes into automated continuous production, significantly improving production efficiency. To ensure that the rotating table does not interfere with the grinding assemblies on both sides during the 180-degree rotation, a first cylindrical cam and a second cylindrical cam, located at both ends of the drive shaft, have curved grooves on their surfaces that engage with the upper and lower driving rollers in the grinding assemblies. These cams drive the grinding assemblies to move to the sides before rotation to effectively avoid interference and drive them to precisely reset after rotation. This linkage mechanism ensures the reliability and smoothness of complex movements and avoids the risk of equipment collisions. A drive motor connected to one side of the first clamping component drives the inner roller to rotate, thereby causing the pipe fixed by the centering clamping assembly to rotate at a uniform speed. Simultaneously, this, in conjunction with the cutting machine on the cutting table, causes the cut end of the pipe to rotate relative to the grinding disc of the upper or lower grinding machine. This achieves simultaneous pipe cutting and circumferential grinding, ensuring the coaxiality and uniformity of the cut and ground surfaces, and significantly reducing processing time per piece. The upper and lower grinding components, working in conjunction with the pipe switching assembly, feature a buffer guide rod and a sleeved buffer spring in the lower grinding component. This allows the lower grinding machine and its top displacement slider to float elastically within a certain range, adapting to the pipe end face and providing flexible, constant grinding pressure. This avoids over-grinding or uneven grinding, ensuring high-quality and consistent grinding results at both ends. Furthermore, the fully automated process greatly reduces manual labor intensity and skill dependence.
