Description

Technical Field

[0001] This invention relates to the field of steel pipe processing equipment technology, and in particular to a steel pipe cutting saw. Background Technology

[0002] Steel pipe is a long, hollow metal profile made of steel as its base material. It is one of the most widely used and consumed steel products in the national economy. Compared with solid steel of the same cross-section, steel pipe is lighter and has a higher material utilization rate while maintaining similar bending and torsional resistance. It combines economic and structural advantages and is widely used in fluid transportation, structural engineering, machinery manufacturing, energy and chemical industries, and other industrial chain scenarios. As a core basic profile, steel pipe needs to be cut to a fixed length according to actual usage requirements.

[0003] Currently available steel pipe cutting and sawing equipment has many shortcomings in actual production applications. For example, the feeding process largely relies on manual placement and feeding of each pipe, resulting in high labor intensity, low feeding efficiency, and the risk of pipe misalignment and jamming due to manual operation, which seriously affects the continuity of subsequent processing. Most equipment can only cut and saw single steel pipes, making it difficult to simultaneously and accurately feed, position, and cut two steel pipes, thus hindering production capacity. During the steel pipe cutting process, the equipment can only clamp and limit the outer wall of the steel pipe, making it prone to radial swaying and deformation during cutting. This is especially true for thin-walled steel pipes, which are prone to edge chipping and elliptical deformation of the pipe opening, making it difficult to guarantee cutting quality. The unloading process requires manual sorting and storage, resulting in low automation and significant safety hazards. Summary of the Invention

[0004] This invention provides a steel pipe cutting and sawing device that automatically sorts and conveys steel pipes one by one using a feeding rack, eliminating the need for manual feeding. This reduces labor intensity and avoids problems such as jamming and misalignment caused by manual operation. The support component completes the synchronous material distribution, positioning, and alignment of two steel pipes, and the pipe feeding component achieves synchronous and precise feeding of two pipes. It can complete the cutting and sawing of two steel pipes at the same time, increasing production capacity by more than double compared to traditional single-pipe processing equipment. After cutting, the device can automatically transfer and unload the steel pipes, requiring no manual intervention throughout the process. This ensures strong processing continuity and greatly improves work efficiency.

[0015] This invention provides a steel pipe cutting and sawing device, comprising a conveyor frame, a pipe inlet assembly, a support assembly, a guide assembly, a feeding rack, a cutting box, a storage box, a sliding plate, and an insertion plate. Steel pipes to be processed are arranged in batches on the feeding rack. The steel pipes are rolled along the feeding chamber towards one side of the conveyor frame by their own gravity. The number of steel pipes entering the feeding chamber is controlled by a limit plate and a third hydraulic lifting rod that drives a movable plate to rise and fall, achieving orderly, sequential feeding of the steel pipes and avoiding jamming caused by simultaneous feeding of multiple pipes. When a steel pipe is fed to the end of the feeding chamber near the conveyor frame, a second hydraulic lifting rod lifts the lifting plate, moving one end of the guide plate to the outside of the feeding chamber. The first steel pipe slides down the inclined guide plate and lands on the top of the bottom support block on the surface of the horizontal plate. Subsequently, the second hydraulic lifting rod lifts the lifting plate again, moving the guide plate to the top of the feeding chamber. The second steel pipe is limited by the bottom area of ​​the guide plate as it rolls. The tube slides down to the top of the bottom support block, completing the synchronous feeding of the two steel pipes. Then, the first hydraulic lifting rod drives the lifting seat to rise and fall, adjusting the height of the horizontal plate and the bottom support block to make the center axis of the two steel pipes completely aligned. Subsequently, the second electric push rod retracts, driving the second side plate to move towards the first side plate, pushing the steel pipe to press against the surface of the limiting seat and the bottom support block, so that the two steel pipes are positioned and clamped in the order of side positioning block, first steel pipe, limiting seat, second steel pipe, and side positioning block, ensuring that no radial deviation occurs during the steel pipe transportation process. After positioning is completed, the drive seat works to drive the moving seat to move along the surface of the guide rail seat, so that the pipe inlet box moves to the end position of the steel pipe. The first electric push rod works to adjust the distance between the two adjusting blocks to match the steel pipe with the corresponding diameter. The stepper motor on the surface of the adjusting block works to push the end of the steel pipe to move at a uniform speed through the adjusting plate, realizing the precise fixed-length feeding of the steel pipe.During the conveying process, the steel pipe passes through the guide assembly and enters the cutting box. The third electric push rod pushes the moving frame to move, adjusting the distance between the two moving frames to fit the outer diameter of the steel pipe. The fourth electric push rod drives the clamping blocks to clamp the two steel pipes from the top and bottom respectively, ensuring the straightness of the steel pipe feeding and preventing shaking or movement during the conveying process. The steel pipe enters the cutting table inside the cutting box and moves to the preset cutting length. The sixth electric push rod drives the sliding plate to move to the outside of the cutting table, so that the insertion plate extends into the end of the steel pipe to be cut. The seventh electric push rod pushes the support block to extend, providing internal support and limiting at the top and bottom of the inner wall of the steel pipe, fixing the end of the steel pipe to be cut. Then the cutting motor works, cooperating with the fourth hydraulic lifting rod to drive the cutting blade holder and cutting blade to move down, performing fixed-length sawing on the steel pipe. After the steel pipe is cut, it is fitted onto the surface of the insertion plate. The sixth electric push rod drives the sliding plate out of the cutting box range, and the electric push rod rotates to... The machine's operation drives the insertion plate and the cut steel pipe to rotate, aligning the pipe opening with the receiving box. Then, the fifth electric push rod moves the slide, causing the push plate to move to the end of the steel pipe. The fifth hydraulic lifting rod then moves the push plate up and down to align the steel pipe. The push plate, moving with the slide, pushes the steel pipe fitted onto the insertion plate into the receiving box, completing the automatic unloading and collection of the steel pipe. The entire equipment uses a feeding rack for automatic sorting and individual conveying of steel pipes, eliminating the need for manual feeding. This reduces labor intensity and avoids jamming and misalignment issues caused by manual operation. The support assembly enables simultaneous material distribution, positioning, and alignment of two steel pipes, and the pipe feeding assembly achieves precise simultaneous feeding of two pipes. It can simultaneously cut and saw two steel pipes, more than doubling production capacity compared to traditional single-pipe processing equipment. After cutting, the steel pipes can be automatically transferred and unloaded, requiring no manual intervention throughout the process. This ensures strong processing continuity and significantly improves work efficiency.

[0021] This embodiment provides a steel pipe cutting and sawing device, which includes a conveyor frame 1, a pipe inlet assembly 2, a support assembly 3, a guide assembly 4, a feeding rack 5, a cutting box 6, a storage box 7, a sliding plate, and an insertion plate 83. Steel pipes to be processed are arranged in batches on the feeding rack 5. The steel pipes are rolled along the feeding chamber 53 towards one side of the conveyor frame 1 by their own gravity. The number of steel pipes entering the feeding chamber 53 is controlled by the lifting and lowering of the movable plate 56 driven by the limiting plate 55 and the third hydraulic lifting rod 57, thus achieving orderly one-by-one conveying of the steel pipes and avoiding multiple steel pipes being cut. Simultaneous conveying of pipes causes a jamming failure. When the steel pipe is conveyed to the end of the feeding chamber 53 near the conveyor frame 1, the second hydraulic lifting rod 351 drives the lifting plate 35 to rise, causing one end of the guide plate 361 to move to the outside of the feeding chamber 53. The first steel pipe slides down onto the top of the bottom support block 39 on the surface of the horizontal plate 38 through the inclined guide plate 361. Then, the second hydraulic lifting rod 351 drives the lifting plate 35 to rise again, causing the guide plate 361 to move to the top of the feeding chamber 53. When the second steel pipe rolls, it is blocked by the bottom of the guide plate 361. The section is limited, and the tubes slide down to the top of the bottom support block 39, completing the synchronous feeding of the two steel pipes. Then, the first hydraulic lifting rod 321 drives the lifting seat 32 to rise and fall, adjusting the height of the horizontal plate 38 and the bottom support block 39 so that the central axes of the two steel pipes are completely aligned. Subsequently, the second electric push rod 341 retracts, driving the second side plate 34 to move towards the first side plate 33, pushing the steel pipes to press against the surface of the limiting seat 36 and the bottom support block 39, so that the two steel pipes are aligned with the side positioning block 37, the first steel pipe, and the... The positioning and clamping of the limit seat 36, the second steel pipe, and the side positioning block 37 are completed in sequence to ensure that the steel pipe does not deviate radially during the conveying process. After the positioning is completed, the drive seat 23 drives the moving seat 22 to move along the surface of the guide rail seat 11, so that the pipe inlet box 21 moves to the end position of the steel pipe. The first electric push rod 26 adjusts the distance between the two adjusting blocks 25 to match the steel pipe with the corresponding diameter. The stepper motor on the surface of the adjusting block 25 drives the end of the steel pipe to move at a uniform speed through the adjusting plate 27 to achieve precise fixed-length feeding of the steel pipe.During the conveying process, the steel pipe passes through the guide assembly 4 and enters the cutting box 6. The third electric push rod 43 pushes the moving frame 42 to move, adjusting the distance between the two moving frames 42 to match the outer diameter of the steel pipe. The fourth electric push rod 45 drives the clamping block 46 to clamp the two steel pipes from the top and bottom respectively, ensuring the straightness of the steel pipe feeding and preventing shaking or movement during the conveying process. The steel pipe enters the cutting table 61 inside the cutting box 6. After moving to the preset cutting length, the sixth electric push rod 81 drives the slide plate 8 to move to the cutting position. The outer side of the cutting table 61 allows the insertion plate 83 to extend into the end of the steel pipe to be cut. The seventh electric push rod 86 pushes the support block 85 to extend, providing internal support and limiting at the top and bottom of the inner wall of the steel pipe to fix the end of the steel pipe to be cut. Then, the cutting motor 65 works, cooperating with the fourth hydraulic lifting rod 661 to drive the cutting blade holder 63 and the cutting blade 631 to move down, performing fixed-length sawing on the steel pipe. After cutting, the steel pipe is fitted onto the surface of the insertion plate 83. The sixth electric push rod 81 drives the sliding plate 8 to exit the cutting box 6. Within the range, the rotating motor 82 drives the insertion plate 83 and the cut steel pipe to rotate, so that the pipe opening faces the receiving box 71. Then, the fifth electric push rod 74 drives the slide 73 to move, so that the push plate 75 moves to the end position of the steel pipe. The fifth hydraulic lifting rod 76 drives the push plate 75 to rise and fall to align the steel pipe. The push plate 75 moves with the slide 73, pushing the steel pipe sleeved on the insertion plate 83 into the receiving box 71, completing the automatic unloading and collection of the steel pipe. The entire equipment automatically sorts the steel pipes through the feeding rack 5. Compared to traditional single-pipe processing equipment, this method eliminates the need for manual feeding, reducing labor intensity and avoiding issues like jamming and misalignment. Support component 3 enables simultaneous material distribution, positioning, and alignment of two steel pipes, while infeed component 2 ensures precise and simultaneous feeding of both pipes. This allows for the simultaneous cutting and sawing of two steel pipes, more than doubling production capacity compared to traditional single-pipe processing equipment. After cutting, the system automatically transfers and unloads the steel pipes, requiring no manual intervention throughout the process. This ensures continuous processing and significantly improves work efficiency.

[0033] In this embodiment, the cutting motor 65 operates, and together with the fourth hydraulic lifting rod 661, it drives the positioning frame 64, the cutting blade holder 63, and the cutting blade 631 to move downward. The positioning frame 64 adjusts its direction inside the fixed seat through the rotating shaft to perform fixed-length sawing on the steel pipe, and simultaneously cuts two horizontally arranged steel pipes at one time.

[0034] In a further embodiment of this invention, the bottom of the cutting box 6 is provided with an ash storage box 67 and a control box 68. A feeding chamber is provided through the cutting box 6 and the ash storage box 67. The feeding chamber is located at the bottom of the cutting groove. A blower is provided at the top of the discharge groove 62 and the feed groove 621. A detection plate is provided on the inner wall of the cutting box 6. An infrared sensor and a distance sensor are provided on the surface of the detection plate. A PLC controller is provided inside the control box 68.

[0035] In this embodiment, the detection plate monitors the length of the steel pipe to be cut in real time. The blower can blow the waste generated during the cutting process into the cutting groove and then into the feeding chamber and accumulate in the ash storage box 67 for centralized collection. There is no need for manual material receiving and sorting operations near the cutting station, avoiding injury from the chips and flying objects generated during the cutting process, and greatly reducing the safety risks in the production process.

[0036] In a further embodiment of this invention, a fifth electric push rod 74 is provided between the slide 73 and the outer wall of the receiving box 71, and the push plate 75 is L-shaped and a fifth hydraulic lifting rod 76 is provided between it and the slide 73.

[0037] In this embodiment, the fifth electric push rod 74 drives the slide 73 to move, causing the push plate 75 to move to the end position of the steel pipe. The fifth hydraulic lifting rod 76 drives the push plate 75 to rise and fall to align with the end of the steel pipe. The fifth electric push rod 74 then drives the slide 73 to retract and move. The push plate 75 moves with the slide 73, pushing the steel pipe sleeved on the insertion plate 83 into the receiving box 71, completing the automatic unloading and collection of the steel pipe.

[0038] In a further embodiment of this invention, a sixth electric push rod 81 is provided between the slide plate 8 and the outer wall of the storage box 7. A rotating motor 82 is provided on the top surface of the slide plate 8. An insertion plate 83 is connected to the output end of the rotating motor 82. The insertion plate 83 is L-shaped and has positioning blocks 84 evenly provided at the top and bottom. A seventh electric push rod 86 is provided between the positioning block 84 and the support block 85.

[0039] In this embodiment, the slide plate 8 is provided with two plates corresponding to two steel pipes to be cut. The sixth electric push rod 81 drives the slide plate 8 to move to the outside of the cutting table 61, so that the insertion plate 83 extends into the end of the steel pipe to be cut. The seventh electric push rod 86 pushes the support block 85 to extend, and provides internal support and limit at the top and bottom of the inner wall of the steel pipe to fix the end of the steel pipe to be cut. After the steel pipe is cut, it is fitted onto the surface of the insertion plate 83. The sixth electric push rod 81 drives the slide plate 8 to exit the range of the cutting box 6. The rotating motor 82 drives the insertion plate 83 and the cut steel pipe to rotate, so that the pipe opening faces the receiving box 71. At the same time, the seventh electric push rod 86 retracts so that the support block 85 is no longer tightly clamped to the inner wall of the steel pipe, making it easier to push it off.
