Description

Technical Field

[0001] This invention relates to the field of metal pipe end face beveling technology, specifically to an integrated automatic metal pipe end face beveling machine. Background Technology

[0002] In metal pipe welding, beveling the pipe ends is a crucial step in ensuring weld quality. Ideally, the pipe end face should be flat and perpendicular to the pipe axis to ensure uniform beveling and good weld penetration. However, in actual projects, metal pipes often develop unevenness or bevels at their ends during cutting, transportation, or on-site installation. Directly beveling pipe ends with these defects can lead to inconsistent bevel angles and uneven blunt edge dimensions, affecting weld joint quality and even causing weld defects.

[0003] Currently, the common method for handling uneven or beveled pipe ends is as follows: First, the pipe end is manually or inspected using a testing device to check its flatness. If unevenness or bevels are found, the pipe is hoisted to a specialized machine tool, where the pipe end face is corrected to a flat and perpendicular state to the axis through cutting. After the end face is corrected, the pipe is then hoisted back to the beveling equipment for beveling. This method of separating beveling and end face correction has the following shortcomings: First, the process is fragmented, requiring multiple hoisting and clamping operations, resulting in low processing efficiency. This is especially true when the pipeline is heavy or the construction site is complex, significantly increasing auxiliary time. Second, the transfer and repositioning of the pipeline between different equipment can easily introduce clamping errors, affecting the accuracy of beveling. Summary of the Invention

[0019] To address the technical problems mentioned in the background section, the following is provided: an integrated automatic beveling machine for metal pipe ends: Combination Figures 1-16 As shown, the present invention provides an integrated automatic beveling machine for metal pipe ends, comprising: a hoisting assembly 100, which includes a top plate 101, the top surface of the top plate 101 is connected to a lifting column 102, one end of the bottom surface of the top plate 101 is vertically connected to an annular assembly plate 103, and the other end is vertically connected to a circular assembly plate 104; an annular processing assembly 200, which is disposed on the inner wall of the annular assembly plate 103, the annular processing assembly 200 including a circularly arranged drive rotating ring 201, a beveling component, a ring cutting component, and a detection component; the beveling component, the ring cutting component, and the detection component are symmetrically arranged in two sets; an inner clamping assembly 300, which horizontally penetrates the middle of the circular assembly plate 104; and a material handling assembly 4. 00, which is installed on the side wall of the circular assembly plate 104; spray assembly 500, which is located on the bottom surface of the top plate 101, for spraying cutting fluid to the end of the pipe; liquid collection tank 600, which is located below the top plate 101, with the bottoms of the annular assembly plate 103 and the circular assembly plate 104 extending into the liquid collection tank 600; the processed end of the metal pipe extends into the top of the liquid collection tank 600; feeding assembly 700, which includes a pushing component, a roller guide frame 701 and an air jet component, the roller guide frame 701 is located on one side of the liquid collection tank 600, the pushing component is located on one side of the roller guide frame 701, and an air jet component is installed on the top of the pushing component, the air jet component is used to blow out the waste chips from the processed end of the metal pipe; The all-in-one machine includes the following processing modes: In the first mode, the detection component checks the flatness of the pipe end face. If the test is qualified, it directly enters the third mode. If it is not qualified, it first enters the second mode and then the third mode. In the second mode, the circumferential cutting component cuts out a defective ring at the end of the pipe to obtain a qualified end face at the end of the pipe, and the defective ring is removed by the material taking component 400. In the third mode, the beveling component beveles the qualified end face of the pipe.

[0020] Through the above structure: 1. The lifting column can achieve adaptive adjustment of the height of the whole machine processing station, which can be adapted to metal pipes of different diameters and specifications, and accurately calibrate the coaxiality of the ring processing component, the inner clamping component and the pipe, thus avoiding problems such as processing eccentricity, uneven beveling and ring cutting deviation from the source. 2. The drive ring, as the rotary drive base, can drive all processing and inspection components to make a 360° circular motion around the pipe end, realizing full-area inspection, circumferential cutting, and beveling of the pipe end face; the three sets of components are symmetrically arranged in two groups, which on the one hand improves the balance of processing and inspection, counteracts the radial stress generated by unilateral operation, and prevents pipe deformation, and on the other hand improves the efficiency of operation, while ensuring uniform processing accuracy at all parts of the circumference and avoiding local processing defects; 3. The inner clamping component extends into the inner wall of the metal pipe and clamps and fixes the inner wall of the metal pipe to prevent the pipe from shifting during circumferential cutting and beveling, which would affect the accuracy of circumferential cutting and beveling. 4. The material handling component enables in-situ clamping and translational removal of waste materials without manual intervention; 5. When performing circumferential cutting and beveling, the spray assembly sprays cutting fluid to quickly reduce the processing temperature of the tool and the pipe, avoiding high-temperature wear of the tool and thermal deformation of the pipe end face. At the same time, it carries away cutting chips, achieving real-time cooling, lubrication and chip reduction in the processing area. 6. The collection tank can fully collect the cutting fluid and metal shavings after spraying, avoiding cutting fluid splashing and shavings scattering and contaminating the equipment and working environment; at the same time, it forms a closed processing area, matching the assembly plate structure to form a closed-loop operation, providing the basic conditions for cutting fluid recycling and centralized filtration and collection of shavings. 7. The roller guide frame in the feeding assembly enables the metal pipe to be placed stably and guided for conveying, reducing friction and shaking during the pipe pushing process. At the same time, the air jet component can blow away residual waste inside the pipe and at the processing port in real time, avoiding the accumulation of waste. 8. The three-stage intelligent processing mode can automatically identify the flatness of the pipe end face. Qualified pipes can directly enter the beveling process, while unqualified pipes are first circumferentially cut and trimmed before beveling. This avoids the problem of beveling scrap caused by directly processing unqualified end faces, and balances processing quality and efficiency, reducing ineffective work.

Through the pneumatic telescopic storage and cross rod linkage expansion structure design in the internal clamping assembly, internal clamping of the pipe is achieved. It can adapt to pipes of different inner diameters, providing uniform clamping force and high fit. It is specifically designed for secondary reinforcement clamping in the circumferential cutting process, preventing pipe displacement during cutting or beveling.

[0025] In this embodiment, the material handling component 400 includes a material handling track 401. A moving groove 105 is symmetrically arranged on one side of the circular assembly plate 104.

[0026] In this embodiment, the pushing component includes a worktable 702. The worktable 702 is mounted on one side of a roller guide frame 701.

The spray assembly achieves a continuous and stable spraying effect, which can effectively reduce tool wear, prevent pipeline thermal deformation, remove processing waste, improve pipeline processing quality and equipment service life, and reduce consumable costs.

[0030] Working principle and usage process of this invention: Step 1: Equipment commissioning and pipeline loading alignment: Workers use hoisting equipment to lift the metal pipe to be processed onto the roller guide frame 701. After the metal pipe is completely stationary and stable, the lifting column 102 and the lifting track 704 are adjusted according to the actual diameter of the metal pipe. By raising and lowering the lifting column 102, the installation height of the circular assembly plate 104 and the annular assembly plate 103 is adjusted to ensure that the centers of the annular processing component 200, the inner clamping component 300, and the material handling component 400 are coaxial with the center of the metal pipe. By adjusting the lifting track 704, the opposing track 705 is ensured to be in the same concentric plane as the center of the metal pipe, thus completing the precise alignment of the equipment and the pipe.

[0031] Step 2: Internal clamping and fixing of the pipe: The screw-type forward guide rail 703 is activated, causing it to move the lifting guide rail 704, the opposing guide rail 705, and the inner gripper 706 forward as a whole, extending the inner gripper 706 into the metal pipe. Once the inner gripper 706 reaches the designated position, the screw-type forward guide rail 703 stops. Then, the opposing guide rail 705 is activated, driving the two sets of inner grippers 706 to expand and move to both sides. By having the inner grippers 706 adhere to the inner wall of the pipe, the metal pipe is clamped and fixed, providing stable support for subsequent pipe moving and processing.

[0032] Step 3: Pipeline pushing and detection component fitting and positioning: After the pipe is clamped and fixed, the screw-type forward guide rail 703 is restarted, driving the opposing guide rail 705 forward, thereby pushing the entire metal pipe to move. The end of the metal pipe passes through the central through hole of the annular assembly plate 103 until it contacts the detection wheel 221. The continuous forward movement of the pipe will squeeze the detection wheel 221, forcing the detection wheel 221 to compress the reset damping rod 222, while simultaneously driving the distance block 223 to move synchronously. The distance sensor 224 monitors the displacement distance of the distance block 223 in real time. When the detection distance returns to zero and the reset damping rod 222 retracts more than half of its stroke, the screw-type forward guide rail 703 stops running immediately, completing the precise positioning of the metal pipe and the detection component.

[0033] Step 4: Pipe end flatness inspection: After the equipment is positioned, the drive motor, in conjunction with the gear ring, drives the rotating ring 201 to rotate, causing the beveling component, circumferential cutting component, and detection component on the disc to make a circular motion around the metal pipe. The detection wheel 221 makes one revolution around the end port of the metal pipe, completing the flatness detection operation.

[0034] If the end face of the metal pipe is uneven, the detection wheel 221 will move horizontally adaptively under the elastic force of the reset damping rod 222, always keeping in contact with the pipe end face, while simultaneously driving the distance block 223 to move horizontally in sync. The distance sensor 224 captures the displacement data changes in real time. If the detection data fluctuates significantly, it is determined that the flatness of the pipe end does not meet the standard and cutting is required; if the detection data does not fluctuate significantly, it indicates that the pipe end is flat and the beveling process can be carried out directly.

[0035] If the test is passed, proceed directly to step six; if the test is failed, proceed to step five first, then to step six. Step 5: Cutting off the ends of pipes with substandard end faces: S5.1, Secondary internal clamping ensures cutting stability: For metal pipes with uneven ends, first remove the detection component from the pipe port, then insert the inner clamping component 300 into the metal pipe for secondary reinforcement and clamping to prevent the pipe from shaking or shifting during the cutting process.

[0036] During clamping operations, the retractable pneumatic rod 301 is first activated, driving the moving block 302 to shift. This causes the column cylinder 303, the first cross rod 304, the second cross rod 307, and the inner clamping plate 308 to extend into the metal pipe as a whole. Once the designated processing depth is reached, the retractable pneumatic rod 301 stops operating. Subsequently, the inner clamping pneumatic rod 305 is activated, driving the second cross rod 307 to rotate. This, in conjunction with the first cross rod 304, causes the inner clamping plate 308 to expand outward, tightly fitting against the inner wall of the pipe, thus completing the internal reinforcement and clamping of the pipe.

[0037] S5.2 Precisely clamp and fix the area to be cut: After the internal reinforcement of the pipeline is completed, the area of ​​the pipeline to be cut is clamped and fixed to facilitate the direct removal of waste material after cutting. The material picking track 401 is started, which drives the inner support track 402, the bent rod 403 and the clamping block 404 to move, so that the clamping block 404 is precisely aligned with the inner wall of the pipeline area to be cut. After positioning is completed, the material picking track 401 is stopped, and the inner support track 402 is started again, which drives the two sets of bent rods 403 to expand the clamping block 404 to both sides, firmly clamping the inner wall of the pipeline area to be cut and locking the cutting position.

[0038] S5.3, Pipe end circumferential cutting: After the clamping is stable, the rotating ring 201 is driven to rotate again, causing the beveling component, circumferential cutting component, and detection component to rotate in a ring. When the circumferential cutting component is working, the circumferential cutting track 210 drives the circumferential cutting guide rod 211 to approach the surface of the metal pipe, and simultaneously drives the cutter holder 212 and the circumferential cutting blade 213 to fit against the outer wall of the pipe, and perform circumferential cutting on the unqualified end area of ​​the pipe to remove the uneven pipe end.

[0039] S5.4 Removal and cleaning of cutting waste: After the pipe cutting operation is completed, the material picking track 401 is started, which drives the inner support track 402, the bent rod 403 and the clamping block 404 to move as a whole, and moves the cut metal scrap ring to the outside of the work area, thoroughly cleaning the processing station and clearing obstacles for subsequent beveling.

[0040] Step 6: Qualified pipe end beveling: Perform pipe end beveling. Start the retractable pneumatic rod 203, which moves the translation guide rail 206, translation guide rod 207, blade sleeve 208, and beveling cutter 209 forward. Once the beveling cutter 209 is aligned with the processing position on the metal pipe end, stop the retractable pneumatic rod 203. Then, start the translation guide rail 206, which drives the translation guide rod 207 to finely adjust the displacement of the blade sleeve 208 and beveling cutter 209, ensuring they fit snugly against the outer wall of the pipe end, thus precisely completing the pipe end beveling process. During the cutting operation, the pump 502 starts simultaneously, drawing cutting fluid from the bottom of the collection tank 601 through the inlet pipe 503 and delivering it to the nozzle 505 via the outlet pipe 504, where it is evenly sprayed onto the metal pipe cutting area. The cutting fluid flows along the pipe surface, carrying metal chips generated during cutting back into the collection tank 601. Under the guidance of the inclined guide plate 602, the cutting fluid containing chips flows into the collection filter frame 605, where the filter frame intercepts the metal chips. The filtered cutting fluid is recycled, and the intercepted chips can be collected and cleaned.

[0041] At the same time, the air blower 707 operates synchronously, delivering outside air to the blower head 709 through the air duct 708. The blower head 709 then blows air into the metal pipe, achieving rapid heat dissipation of the inner wall of the pipe and blowing away residual debris to prevent debris from remaining inside the pipe and affecting processing accuracy.

[0042] Step 7: Reset the pipeline to its original position and transfer it to the next workstation. After all beveling processes are completed, the feeding assembly 700 drives the metal pipe to retract in the opposite direction, moving the pipe end out of the working area above the collection tank 600, and the equipment resets to standby. The processed metal pipe can be transferred to the next processing station via hoisting equipment to complete the entire process.
