Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe grooving, and in particular to an intelligent steel pipe grooving device and a grooving method. Background Art

[0002] Steel pipe end processing equipment, especially processing equipment for grooving steel pipe ends, currently usually performs grooving operations on the ends by a group of rolling convex and concave roller wheels, that is, the steel pipe is pulled onto the groove wheel by a power device for rotation, and the convex roller wheel presses down on the outer wall of the steel pipe on the groove wheel to roll out the groove of the steel pipe end; and the power mechanical part used for grooving the steel pipe is currently assembled on a frame, and the frame is placed flat on the ground during operation, and a steel pipe support frame placed on the same floor surface is also configured, and the steel pipe can be grooved at the end.

[0003] However, since the power machinery part of the steel pipe grooving operation is separate from the bracket supporting the steel pipe, the support frame is unstable and may move or swing arbitrarily, it cannot be guaranteed that the pipe end of the grooving operation will be stably maintained at the specified position of the pipe bracket. In addition, due to the influence of the excessive inclination of the steel pipe end and the difference in manual operation technology, the final groove size of the steel pipe end is different, which is the main factor causing pipeline leakage.

[0004] Although some patent documents have proposed various improvement measures and methods for the grooving device, the grooving device still lacks an automatic intelligent identification control system, an overall measurement and adjustment processing mechanical system, an overall operation stabilization system, and an auxiliary processing mechanical system for processing and correcting the bevel, ovality, and local deformation of the pipe port. In addition, there is also a lack of standard operating process flow, and the processing operation depends entirely on the operating experience of the staff, rather than realizing the automatic grooving operation of the steel pipe through the technical performance of the grooving equipment. Therefore, the current steel pipe port grooving processing equipment not only has low grooving processing accuracy and efficiency, but also cannot meet the requirements of medium and large diameter port grooving processing, and cannot even meet the processing accuracy requirements of steel pipes with a diameter of less than 300 mm, let alone good grooving operations for steel pipes with a diameter of more than 500 mm, which greatly limits the use of grooved steel pipe products.

[0005] Moreover, the steel pipe ports processed by the existing steel pipe port grooving equipment will present elliptical bell mouths, flat bevel bell mouths, drum-shaped bell mouths, and twisted bell mouths. The larger the diameter of the steel pipe, the larger and more irregular the port deformation after the grooving operation, which seriously affects the sealing of the pipeline interface. The existing processing equipment, processing workers and technicians are simply unable to control the deformation of the port after grooving. How to solve the deformation of the port after the grooving operation is also a difficult problem in the industry. Summary of the invention

[0022] S1, check whether the slotting machine is suitable for the steel pipe to be processed, whether the component configuration of the slotting machine is correct, whether the working state of the slotting machine is normal, and whether it can meet the requirements for steel pipe port forming. If the above checks are all yes, the slotting machine is in standby state.

[0023] S2, inspect whether the end of the steel pipe to be processed is qualified. If the acceptance is qualified, enter S3. If the acceptance is unqualified, adjust the steel pipe to be processed until it is qualified.

[0024] S3, placing the steel pipe to be processed on the predetermined pipe position of the adjustable steel pipe support platform. Under the control of the intelligent control system, the steel pipe on the adjustable steel pipe support platform starts to rotate at a low speed, and at the same time starts to adjust and measure the horizontal straightness of the steel pipe and the verticality of the port. When the measurement results meet the parameter requirements of the steel pipe grooving, proceed to S4.

[0025] S4, under the control of the intelligent control system, measures the inclination of the steel pipe port, starts the flattening machine and the flattening fixture for temporarily positioning the steel pipe, and begins flattening the steel pipe port to eliminate the port tolerance that affects the grooving accuracy. When the port tolerance detection is qualified, enter S5.

[0026] S5, the steel pipe with qualified port size is transmitted to the groove forming part of the groove pressing machine. After being detected and found to be correct, the steel pipe is controlled to rotate at a low speed under the control of the intelligent control system.

After the grooving depth data, the arc flatness data of the pipe end face, the roundness data of the steel pipe, the length dimension data of the pipe end and the pipe diameter data all meet the operation requirements, enter S7.

[0028] S7, under the control of the intelligent control system, the steel pipe is transported to the pipe position before the flat end operation, and after the steel pipe is in place correctly, enter S8.

[0029] Furthermore, when the other end of the steel pipe also needs to be grooved, the automatic rotating device rotates the steel pipe horizontally 180 degrees under the control of the intelligent control system, and repeats the above method to complete the grooving operation at the other end of the steel pipe; optionally, if the intelligent grooving device is equipped with a double grooving machine, the steel pipe does not need to turn around, and can pass through the steel pipe unloading device and directly enter the next grooving machine for grooving to complete the grooving operation.

[0050] Embodiment 1

[0051] like Figure 1-8As shown, the present invention provides an intelligent steel pipe grooving device, including a grooving machine, a flat-end machine 11, an adjustable steel pipe supporting platform 15, a flat-end fixing device 23, a common machine frame 28 and an intelligent control system. The grooving machine is installed at the end of one end of the common machine frame 28, the flat-end machine 11, the adjustable steel pipe supporting platform 15, and the flat-end fixing device 23 are all slidably arranged on the common machine frame 28, and the common machine frame 28 is a common frame seat of the grooving machine, the flat-end machine 11, the adjustable steel pipe supporting platform 15 and the flat-end fixing device 23. The intelligent control system intelligently controls the grooving machine, the flat-end machine 11, the adjustable steel pipe supporting platform 15 and the flat-end fixing device 23 according to the requirements of the steel pipe port processing operation.

[0052] The slotting machine is arranged at the end of one end of the common machine frame 28, and is used for slotting the steel pipe end. The slotting machine frame is provided with a power motor 1 and a main shaft 35 connected to the output end of the power motor 1. An adjustable sizing plate 42a, a flattening wheel 8, and a concave wheel 45 are sequentially sleeved on the main shaft 35. The flattening wheel 8 is closer to the power motor 1 than the concave wheel 45. The adjustable sizing plate 42a is used to adjust the length of the slotting port. The concave wheel 45 is the main power wheel and can pull the steel pipe to perform a circular rotation motion. The slotting machine is also provided with a cam assembly device 7. The cam assembly device 7 cooperates with the concave wheel 45 to slot the steel pipe end. The cam assembly device 7 is provided with a cam assembly device 7 ... A cam 47 and an A-type cam back-pressure support roller group 46 are installed on the device 7. The surface of the A-type cam back-pressure support roller group 46 is formed with a first annular groove that is compatible with the cam 47. The cam 47 is embedded in the first annular groove. The A-type cam back-pressure support roller group 46 is provided with a first back-pressure wheel that acts on the cam 47. During the groove pressing process, the first back-pressure wheel of the A-type cam back-pressure support roller group 46 provides pressure support to the cam 47 and rotates with the cam 47, thereby improving the force-bearing performance and service life of the cam 47.

[0053] The cam assembly device 7 is connected to the hydraulic transmission device 6, and the hydraulic cylinder 5 is installed on the head 27 of the groove pressing machine frame. The hydraulic transmission device 6 reciprocates in the vertical direction under the action of the hydraulic cylinder 5, thereby driving the cam 47 to move up and down. During the groove pressing operation, under the control of the intelligent control system, the cam 47 moves downward, and the peripheral side wall of the groove pressing port of the steel pipe 44 is clamped between the cam 47 and the concave wheel 45. The contact point between the cam 47 and the steel pipe 44 and the contact point between the concave wheel 45 and the steel pipe 44 are on the same radius line of the circumferential cross section of the steel pipe 44.

[0054] The groove pressing machine base is also provided with a shape correction component, a centripetal roller device 41, and an automatic measuring system 10. Under the control of the intelligent control system, the automatic measuring system completes the detection of various parameters of the port to be grooved of the steel pipe 44, such as the port slope tolerance, the verticality of the pipe body, the pipe rotation speed, etc., and then according to the measurement results of the automatic measuring system, the shape correction component is used to correct the shape of the steel pipe after the port is grooved, and the centripetal roller device 41 can adjust the verticality of the concentric circle of the groove pressing port and the steel pipe body.

On the horizontal line of the center of the circle, two centripetal roller device slideways 40 are symmetrically arranged on the left and right sides of the center of the circle, and on the vertical line of the center of the circle, one centripetal roller device slideway 40 is arranged on the lower side of the center of the circle, and the extension lines of the three tube centripetal rollers 39 intersect at the center of the circle. During the grooving process of the steel pipe port, based on the measurement results of the automatic measuring system 10, under the control of the intelligent control system, the position of the adjustable centripetal circumferential roller seat is adjusted, and the tube circle centripetal roller 39 slides along the centripetal roller device slide 40 to control the steel pipe port within the range restricted by the three tube circle centripetal rollers 39, thereby ensuring the verticality between the steel pipe port and the steel pipe body.

[0056] The shape correction component includes a shape correction control wheel group, an inner shape correction wheel group 43 and a shape correction control wheel power transmission device 37. The shape correction control wheel group includes an A-type shape correction control wheel group 38 and a B-type shape correction control wheel group 9. The size of the A-type shape correction control wheel group 38 is smaller than that of the B-type shape correction control wheel group 9. The A-type shape correction control wheel group 38, the B-type shape correction control wheel group 9 and the inner shape correction wheel group 43 are respectively connected to the shape correction control wheel power transmission device 37. In this embodiment, two groups of the A-type shape correction control wheel groups 38, two groups of the B-type shape correction control wheel groups 9 and two groups of the inner shape correction wheel groups 43 are symmetrically arranged at positions near the groove pressing points on both sides of the cam group device 7. After the steel pipe port is qualified by grooving, under the control of the intelligent control system, the shape correction control wheel power transmission device 37 drives the A-type shape correction control wheel group 38, the B-type shape correction control wheel group 9 and the inner shape correction wheel group 43 to move toward the wall of the steel pipe 44, and the A-type shape correction control wheel group 38 and the B-type shape correction control wheel group 9 are pressed against the outer wall surface of the steel pipe 44 respectively, and the inner shape correction wheel group 43 is pressed against the inner wall surface of the steel pipe 44, and then cooperate with the flattening wheel to correct the port after grooving.

When the steel pipe rotating along its own circumference needs to be temporarily fixed, under the control of the intelligent control system, the flat-mouth roller vertical lifting device 21 and the flat-mouth fixing device moving mechanism 24 adjust the front and rear positions and vertical heights of the flat-mouth fixed pressure wheel 20 and the flat-mouth horizontal fixed roller 22, so that the flat-mouth fixed pressure wheel 20 presses down against the inner wall of the lowest point of the steel pipe wall, and the flat-mouth horizontal fixed roller 22 presses against the peripheral edge of the circumference of the steel pipe wall, thereby realizing temporary fixation of the steel pipe.

[0071] Embodiment 3

[0072] Based on the intelligent steel pipe grooving device proposed by the present invention, the present invention also relates to a grooving method of the intelligent steel pipe grooving device, wherein the intelligent steel pipe grooving device includes a grooving machine, an adjustable steel pipe support platform 15, a flat machine 11, a common machine frame 28 and an intelligent control system, wherein the grooving machine is installed at the end of one end of the common machine frame 28, the adjustable steel pipe support platform 15 and the flat machine 11 are slidably arranged on the common machine frame 28, and the intelligent control system intelligently controls the grooving machine, the flat machine 11 and the adjustable steel pipe support platform 15 according to the requirements of the steel pipe port processing operation, and the operation steps of the intelligent steel pipe grooving device are as follows:

[0073] S1, check whether the groove pressing device is suitable for the steel pipe to be processed, whether the cam group device and the concave wheel for groove pressing are correct, whether the groove pressing device works normally and whether it can meet the requirements of steel pipe end forming. If the above checks are all yes, the groove pressing machine is in standby state.

[0074] S2, check whether the steel pipe to be processed meets the standards, especially whether the port is qualified. Grind the weld part of the welded joint of the steel pipe port to be grooved that is higher than the pipe surface, clean the burrs on the pipe mouth, and clean the debris, dirt, welding slag on the pipe wall surface to keep the pipe surface clean. If the acceptance is qualified, enter S3. If the acceptance is unqualified, continue to adjust the steel pipe to be processed until it is qualified.

[0075] S3, placing the steel pipe to be processed on the supporting elastic roller of the adjustable steel pipe supporting platform 15, under the control of the intelligent control system, the supporting elastic roller on the adjustable steel pipe supporting platform 15 drives the steel pipe to rotate at a low speed, and at the same time starts to adjust and measure the horizontal straightness of the steel pipe and the verticality of the port, and after the measured steel pipe meets the groove pressing parameter requirements, proceed to S4.

[0076] Optionally, the steel pipe to be processed can also be driven by an independently arranged rotatable device to rotate at a low speed.

[0077] S4, under the control of the intelligent control system, the automatic measuring system 10 on the groover frame measures the inclination of the steel pipe port, the steel pipe bracket 34 on the adjustable steel pipe support platform 15 drives the steel pipe to move along the length direction of the steel pipe, the flattening machine 11 and the flattening fixture 23 for temporarily positioning the steel pipe are started, and the ports with out-of-tolerance are flattened to eliminate the out-of-tolerance of the steel pipe end. After passing the inspection, the flattening machine 11 and the flattening fixture are restored to the original standby position, the supporting elastic roller stops rotating, and enters S5 after the steel pipe is still.

[0078] Optionally, this step can also be performed by pre-finishing the flat-end operation on an independent flat-end device with the same operation control conditions. However, even for steel pipes that have undergone pre-finishing the flat-end operation, they must pass the inspection before entering S5. Preferably, the flat-end equipment can be mechanical equipment, or it can be laser cutting equipment, flame cutting equipment, etc.

[0079] S5, the steel pipe with qualified port size is slowly and automatically positioned to the groove forming part of the groove pressing machine by the steel pipe bracket arranged on the adjustable steel pipe support platform 15. After the automatic measuring system 10 detects that the steel pipe is correctly positioned, it starts the supporting elastic rotating power wheel group 30 (or an independently arranged rotatable device) to make the steel pipe start to rotate at a low speed, and starts the adjustable sizing plate 42a (or sizing roller 42) arranged on the flat plate of the groove pressing machine base and the pipe circle centripetal roller 39 around the circumference of the steel pipe to control the perpendicularity of the pipe port and the steel pipe body, and automatically adjusts the concentricity, verticality, parallelism and sizing length of the steel pipe. After the above parameters meet the processing requirements, the steel pipe bracket returns to the standby position and enters S6.

[0080] S5 specifically includes a test run, in which the intelligent control system controls the rotation of the steel pipe, automatically checks various parameters of the steel pipe and confirms whether they are normal, such as center balance, concentricity, verticality, parallelism, and fixed length. For steel pipes that do not meet the positioning tolerance, fine-tuning correction is performed. After the data shows that it meets the standard, the steel pipe bracket 34 returns to the standby position, but the steel pipe that still fails the fine-tuning correction is exited from the operation.

[0081] S6, under the control of the intelligent control system, the supporting elastic roller accelerates the rotation speed, and at the same time, the power motor 1 drives the main shaft 35 to rotate the steel pipe at the same speed as the supporting elastic roller. When the speed of the steel pipe reaches the same speed as the cam 47 of the groove pressing machine and is stable, the hydraulic cylinder 5 is automatically turned on to slowly press the cam 47 down. When the cam 47 hits the surface of the steel pipe, the cam 47 starts the groove pressing operation according to the rolling pass and rolling depth requirements until the groove depth that meets the requirements is pressed out. Then, the shaping component and the flattening wheel 8 on the groove pressing machine are turned on to start shaping the bell mouth after groove pressing until the port meets the specified control parameters and enters S7.

[0082] In this step, the cam's downward pressure and the number of passes are designed according to the material, pipe diameter, and wall thickness of different steel pipes; after the steel pipe groove depth reaches the preset depth size, when the cam is pressed into the outer wall of the steel pipe to reach the set position, the bell-mouth-eliminating shaping component and the flattening wheel 8 start working, that is, when the groove depth reaches more than 95% of the forming depth, the centripetal shaping component and the flattening wheel 8 perform the flattening, diameter correction, and roundness correction processes in turn; after completing the groove pressing, flattening, diameter correction, and roundness correction operations, the artificial intelligence operation interface of the groove pressing machine displays the groove depth data, pipe end face arc flatness data, steel pipe roundness data, pipe port length size data, and pipe diameter data. After all the data are qualified and recorded, the steel pipe gradually stops rotating, and the groove pressing machine exits the operating state and returns to the standby state.

[0083] S7, start the steel pipe roller device, and transport the steel pipe to the pipe position before the flat-end operation, that is, the set position for installing the steel pipe. After the steel pipe is in place correctly, the steel pipe roller device enters the standby reset state and enters S8.

[0084] When the other end of the steel pipe also needs to be grooved, the automatic rotating device rotates the steel pipe 180 degrees in the horizontal plane under the control of the intelligent control system, and repeats the above method to complete the grooving operation at the other end of the steel pipe; optionally, if the intelligent grooving device is equipped with a double grooving machine, the steel pipe does not need to turn around, and can pass through the steel pipe unloading device and directly enter the next grooving machine for grooving to complete the grooving operation.

[0085] S8, move the steel pipe with the grooved end away from the groove pressing machine table.

[0086] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
