Description

Technical Field

[0001] The present invention relates to the technical field of metal pipe cutting, in particular to a metal pipe cutting device used for manufacturing an integrated pump station. Background Art

[0002] An integrated pumping station is an integrated sewage treatment or drainage lifting equipment. It integrates multiple components required for a traditional pumping station, such as water pumps, screens, valves, control systems, pipes, etc., into a compact prefabricated cylinder to form a complete pumping station system. In the manufacturing process of an integrated pumping station, metal pipe fittings are the key part of connecting various components and building a complete transmission pipeline. Their specifications must strictly comply with the design standards to ensure the smooth operation of the pipeline system and the overall performance of the pumping station. Therefore, in the manufacturing process, cutting and trimming of metal pipe fittings is an essential step.

[0003] Existing metal pipe cutting devices usually adopt a cutting method of pipe rotation combined with fixed tools. However, in the manufacturing process of integrated pump stations, the metal pipes used are mostly manufactured through specific processes (such as mud filling and molding, etc.), which often lead to slight errors in the shape and position of the pipes, such as roundness and straightness (such errors are extremely subtle and difficult to detect with the naked eye). Therefore, in the actual cutting process, since the metal pipes may have roundness deviation or straightness deviation, the metal pipes and their axes will fluctuate up and down during the rotation process. Once this fluctuation exceeds a certain range, it will directly interfere with the normal cutting work and easily cause damage to the entire cutting device. At the same time, if the axis of the metal pipe is skewed due to straightness deviation or local deformation, when the metal pipe is rotated and cut, it will directly cause the problem of skewed cutting, thereby reducing the cutting quality. The reduction in cutting quality will directly cause the pipe specifications to not meet the requirements, thereby affecting the pipeline connection accuracy, sealing and overall operating performance of the entire integrated pump station system, and the practicality is poor. Summary of the Invention

The end of the connecting rod 64 away from the support leg 62 is rotatably connected to the slider 610.

[0039] The present invention is applied to the cutting of large-diameter pipe fittings in the manufacture of large and medium-sized pump stations. When the metal pipe 7 needs to be cut, the metal pipe 7 is first placed on each supporting wheel 4 provided on the base 1 through external lifting equipment, and then the angle of the supporting wheel 4 is adjusted by controlling the electric cylinder 1 41 so that the metal pipe 7 and the inner cavity 22 are in a concentric state. Then, the limit seat 2 is moved toward the metal pipe 7 by controlling the driving part 21 and supporting the metal pipe 7. Under the driving of the driving part 21 and the rolling cooperation of the supporting wheel 4, the limit seat 2 is moved. The position seat 2 moves at a constant speed against the metal tube 7. During this process, the laser distance sensor 58 installed on the outer ring 5 will detect the distance between the outer ring 5 and the limit seat 2 in real time, and feed back the detection data to the control assembly. When the laser distance sensor 58 detects that the distance between the outer ring 5 and the limit seat 2 reaches the preset value (that is, when it meets the cutting distance), the driving part 21 is immediately turned off, so that the limit seat 2 stops pushing the metal tube 7. At this time, the part of the metal tube 7 to be cut will ideally be at the cutting point (that is, at the outer ring 5).

[0040] In the process of the above-mentioned metal tube 7 moving with the limit seat 2, the rigid chain conveyor 3 synchronously outputs the rigid chain 31 at a uniform speed. At this time, the rigid chain 31 extends and pushes the inner ring 6 to move toward the metal tube 7 (before pushing the inner ring 6, the inner ring 6 is in the inner cavity 22). After the inner ring 6 enters the metal tube 7, the spring 611 in the slide groove 68 on the outer cylinder 67 will begin to rebound and pull the slider 610 to slide on the slide rod 69. As the slider 610 slides, the connecting rod 64 lifts the support leg 62 and spreads the support leg 62, so that the universal wheel 63 on the support leg 62 contacts the inner wall of the metal tube 7. Afterwards, under the push of the continuous extension of the rigid chain 31, the inner ring 6 will move forward at a uniform speed in the metal tube 7. In the above-mentioned movement of the inner ring 6, when the inner ring 6 approaches the metal tube 7 When the inner ring 6 is in the metal tube 7, the inclined surface provided at the opening of the inner cavity 22 can provide guidance and buffering for the support legs 62 and the universal wheels 63 on the outer cylinder 67, so that the inner ring 6 can smoothly enter the metal tube 7 after being buffered by the inclined surface, effectively avoiding the support legs 62 from being damaged due to excessive opening at the moment of entering the metal tube 7. In addition, if the metal tube 7 has problems such as straightness deviation or local deformation, its axis will be offset. Since the rigid chain 31 is connected to the inner ring 6 through a universal joint, and this connection method can give the inner ring 6 a certain flexibility, therefore, when the inner ring 6 moves in the metal tube 7 through the universal wheel 63, it can automatically fine-tune its own orientation according to the possible errors such as the axis offset of the metal tube 7, so as to better adapt to the actual situation of the metal tube 7.

[0041] At the same time, the laser distance sensor 2 61 installed on the outer cylinder 67 can detect the distance between the inner ring 6 and the receiving plate 32 in real time, and feed back the detection data to the control assembly. When the laser distance sensor 2 61 detects that the distance between the inner ring 6 and the limit seat 2 reaches the preset value, the rigid chain conveyor 3 is closed. At this time, the position of the inner ring 6 will correspond to the position of the outer ring 5. Since the metal pipe 7 used in the pump station is large in volume, when the part to be cut of the metal pipe 7 reaches the cutting point and stops moving, the metal pipe 7 may slide forward for a distance under the action of inertia. At this time, the rotary cylinder 612 in the cavity is turned on, causing the turntable 614 to rotate clockwise (the direction of rotation is Figure 9 As a reference), under the guidance and pushing action of the multiple guide grooves 615 on the rotating turntable 614, the rollers 616 connected between the corresponding reinforcing rods 65 will extend out of the movable groove and contact the inner wall of the metal tube 7, thereby providing effective internal support for the metal tube 7 and clamping and fixing the metal tube 7. After that, the rigid chain conveyor 3 is controlled to retract the rigid chain 31 and pull the metal tube 7 backward until the laser ranging sensor 2 61 detects that the distance between it and the limit seat 2 meets the cutting distance, and then stops pulling the metal tube 7.

[0042] After completing the above work, the coil in the annular protective cover 56 is energized to uniformly heat the portion of the metal tube 7 to be cut. The annular protective cover 56 is used to protect the coil to prevent the coil from being corroded or damaged by splashing waste liquid and debris during cutting. After heating for a period of time, the coil is powered off and the heating is stopped. The heating of the coil can preheat the portion of the metal tube 7 to be cut, thereby effectively reducing the generation of thermal stress and preventing the occurrence of cold cracks, thereby effectively improving the cutting quality of the metal tube 7. At the same time, the electric cylinder 2 51 is turned on to push the L-shaped rotating rod 54 toward the metal tube 7 until the L-shaped rotating rod 54 drives the driving wheel 55 to press the outer wall of the metal tube 7. Then the driving wheel 55 is started. Under the drive of the driving wheel 55 and the follow-up action of the roller 42 on the support wheel 4, the metal tube 7 begins to rotate at a uniform speed. At this time, the limit seat 2 is reset to the origin by controlling the driving part 21 (at this time, the distance between the limit seat 2 and the laser ranging sensor 1 58 and the distance between the limit seat 2 and the laser ranging sensor 2 61 are still the same).

[0043] Since the inner cylinder 66 in the inner ring 6 is rotatably connected to the cavity in the outer cylinder 67 through the bearing 613, and the circular plate 1 and the circular plate 2 are fixedly installed on the inner cylinder 66, as the metal tube 7 rotates, the reinforcing rod 65 in the circular plate 1 and the circular plate 2 and the inner cylinder 66 will rotate synchronously. At this time, the outer cylinder 67 remains stationary due to the connection with the rigid chain 31, and rotates relatively with the inner wall through the contact between the universal wheel 63 and the inner wall. When the metal tube 7 rotates, by opening the nozzle 53 The coolant in the external liquid supply device is sprayed onto the metal tube 7 to be cut, and at the same time, the electric cylinder 3 52 is turned on to move the cutting machine 57 downward to cooperate with the rotation of the metal tube 7 to perform rotational cutting on the metal tube 7. The splashing waste liquid and debris during cutting are thrown out by the cutting machine 57 and blocked by the outer ring 5 and the mounting frame 2 on the outer ring 5. Finally, the waste liquid will carry the chips and slide down along the inner wall of the outer ring 5, and slide through the through-hole into the sewage collection tank 11. The maintenance personnel only need to clean the sewage collection tank 11 regularly.

[0044] If the metal tube 7 to be cut has problems such as roundness deviation or straightness deviation, the rotating metal tube 7 and its axis will fluctuate up and down during the cutting process. When the fluctuation is too large (the metal tube 7 with excessive fluctuation will directly interfere with the normal cutting work and may cause damage to the rotating cutting mechanism), the laser emitted by the second laser ranging sensor 61 will exceed the range of the receiving plate 32. Once this happens, the alarm mechanism of the control assembly will be immediately triggered and the output ends of the second electric cylinder 51 and the third electric cylinder 52 will be reset to remind the staff to deal with the metal tube 7 in time and stop the rotating cutting of the metal tube 7, thereby protecting the rotating cutting mechanism from collision damage, thereby effectively extending the service life of the entire device.

[0045] When the metal tube 7 to be cut is rotated, if the metal tube 7 only has a roundness deviation problem, the fluctuation during the rotation process is small, and the laser emitted by the laser ranging sensor 2 61 does not exceed the receiving range of the receiving plate 32, the metal tube 7 can be rotated and cut normally. However, if the metal tube 7 has problems such as straightness deviation or local deformation, causing the axis to be skewed, even if the laser of the laser ranging sensor 2 61 does not exceed the range of the receiving plate 32 during the rotation cutting, the cutting will be skewed. At this time, when the metal tube 7 with problems such as straightness deviation or local deformation is rotated, the inner ring 6 inside it will be skewed along with the axis of the metal tube 7, and the control assembly will compare the laser beam to determine the axis of the metal tube 7. The distance data from the optical ranging sensor 1 58 and the laser ranging sensor 2 61 to the limit seat 2 is used to judge the actual situation of the metal tube 7. When the comparison value exceeds the set range, it means that the inner ring 6 on which the laser ranging sensor 2 61 is installed is skewed to a large extent (that is, the cutting position is skewed to a large extent during cutting) and needs to be adjusted. At this time, the output ends of the electric cylinder 2 51 and the electric cylinder 3 52 are reset, and the rotational cutting of the metal tube 7 is stopped. The position of the metal tube 7 is adjusted accordingly by utilizing the rigid chain 31 and the inner ring 6, and then the cutting work is continued to ensure the parallelism of the cutting mouth relative to the limit seat 2, thereby effectively ensuring the cutting quality of the metal tube 7 with straightness deviation problems.

[0046] When the comparison value exceeds the set range or even fails to measure the distance, the alarm mechanism of the control assembly will be immediately triggered and the output terminals of the electric cylinder 2 51 and the electric cylinder 3 52 will be reset to remind the staff to deal with the metal tube 7 in time and stop the rotation cutting of the metal tube 7, thereby protecting the rotation cutting mechanism from collision damage. When the comparison value does not exceed the set range, normal rotation cutting is required. When the metal tube 7 is rotationally cut, the internal support of the multiple reinforcing rods 65 can effectively enhance the structural strength of the cutting part of the metal tube 7, avoid deformation of the metal tube 7 due to pressure during the cutting process, and thus prevent the generation of cracks. At the same time, it can also suppress vibration when cutting the metal tube 7, thereby greatly improving the cutting quality. At the same time, the downward pressure of the driving wheel 55 and the cooperation with the support wheel 4 can provide stable external support for the metal tube 7 and ensure the stable rotation of the metal tube 7 during the cutting process, thereby further suppressing vibration when cutting the metal tube 7 and preventing the metal tube 7 from deflecting during the rotation process, making the cutting surface smoother and further improving the cutting quality.

[0047] After the metal tube 7 is cut, the rotary cylinder 612 is controlled to rotate the turntable 614 counterclockwise (the direction of rotation is Figure 9As a reference), the reinforcing rod 65 is separated from the inner wall of the metal tube 7. Then, the limiting seat 2 is pushed forward a corresponding distance by controlling the driving part 21, and the above-mentioned cutting operation is repeated. When the cut metal tube 7 is advanced a corresponding distance, it will be squeezed to the end of the base 1 and wait for the external lifting equipment to lift it away, thereby realizing the synchronization of cutting and lifting operations, so that the metal tube 7 can be lifted immediately after cutting, which greatly shortens the production cycle of the metal tube 7. When the entire metal tube 7 cutting work is completed, the reinforcing rod 65 is separated from the inner wall of the metal tube 7. At the same time, the rigid chain conveyor 3 pulls the inner ring 6 back to its original position through the rigid chain 31. During the return process of the inner ring 6, the support legs 62 and the connecting rod 64 thereon will enter the inner cavity 22 under the guidance of the inclined surface. At this time, the support legs 62 at the inclined surface are compressed and drive the slider 610 to compress the spring 611 until the inner ring 6 is completely restored. After the restoration, the inner ring 6 stays in the inner cavity 22 and waits for the next metal tube 7 cutting work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
