Description

Technical Field

[0001] The present invention relates to the technical field of equipment manufacturing, and specifically discloses a cutting device for the threaded gas-tight joint of oil casing based on industrial machinery manufacturing. Background Art

[0002] In oil extraction operations, as a key component to ensure the safe and stable operation of oil wells, the gas-tight performance of the connection part of the oil casing is crucial. The threaded gas-tight joint is the core structure for realizing the reliable connection and sealing of the oil casing, and its processing accuracy and quality directly affect the sealing performance, connection strength and service life of the oil casing under complex downhole conditions.

[0003] Currently, during the processing of the threaded gas-tight joint of the oil casing, it is necessary to remove excess material through a cutting device to obtain the specified geometric shape, size and surface quality of the workpiece. The traditional cutting device for the threaded gas-tight joint of the oil casing uses the method of spraying coolant to cool the cutting tool head, and at the same time can clean up the waste chips. When draining water, a filter screen is set inside the device to separate the waste chips from the cooling water. However, after using the filter screen for a period of time, it needs to be manually disassembled and the filter box needs to be pulled out for cleaning, which is cumbersome to operate and increases the cleaning difficulty.

[0004] To solve the problem of cumbersome filter screen cleaning, a certain cutting processing device in the market uses the method of vibrating the filter screen for cleaning, and has a certain market share. For example, the specification of Chinese Patent CN117718795A discloses a cutting processing device for metal seals, including a base, a fuselage shell, a filter box, two jigs and a spray cooling mechanism. A guard plate is fixedly connected to the top of the base, and a funnel is fixedly connected between the two sides of the bottom of the inner wall of the guard plate. A first motor is fixedly connected to one side of the filter box. The present invention relates to the technical field of metal seal processing. In this cutting processing device for metal seals, after the waste water and waste chips enter the filter cylinder through the funnel, the first motor drives the filter cylinder to rotate and filter, accelerating the separation of the waste chips from the cooling water. At the same time, the electric push rod drives the toothed plate to move up and down. The toothed plate drives the rotating rod to rotate back and forth through the gear, and the rotating rod drives the knocking hammer to continuously knock on the rotating filter cylinder, shaking out the waste chips and other impurities blocked in the filter holes of the filter cylinder, automatically cleaning the filter cylinder, without repeated disassembly and cleaning, reducing the cleaning difficulty, and saving manpower and time.

[0005] Based on the above retrieval and combined with the existing technology, the following deficiencies are found: The existing technology uses a percussion hammer to strike the filter cartridge to carry out the cleaning operation. However, this percussion method not only generates a certain amount of noise pollution, which is not conducive to the working environment of the staff, but also causes damage to the filter cartridge during the long-term percussion process, affecting the life of the filter cartridge. Moreover, since some waste chips are stuck firmly at the filter holes, percussion cannot completely shake out all the waste chips and impurities at the filter holes, making it difficult to clean the waste chips thoroughly. Therefore, a cutting device for the threaded gas seal joint of the oil casing pipe based on industrial machinery manufacturing is proposed to improve the above problems. Summary of the Invention

[0016] A cutting method for a threaded gas-tight joint of an oil casing pipe, according to a cutting device for a threaded gas-tight joint of an oil casing pipe based on industrial machinery manufacturing, includes the following steps:

[0017] Step 1: Open the box door, place the oil casing pipe in the three-jaw chuck and contact the positioning bracket, and use the three-jaw chuck to fixedly clamp the oil casing pipe, then close the box door;

[0018] Step 2: Control the cutting assembly to work through the controller. Drive the cutting head to rotate under the action of the driver, and gradually lower the height of the cutting head under the action of the hydraulic cylinder, so as to perform one of the thread cutting operations on the oil casing pipe;

[0019] Step 3: During the implementation of Step 2, synchronously control the spraying assembly to work through the controller. Use the spraying assembly to extract the coolant in the water storage tank and spray it at the cutting position to perform a cooling and cleaning operation. The waste water and waste chips after cleaning will enter the water storage tank along the funnel and perform a solid-liquid filtration operation under the action of the filter cloth;

[0020] Step 4. After the above steps are completed, the cutting assembly stops working and resets, the spray assembly also stops working, and the three-jaw chuck and the oil casing are turned 180 degrees under the operation of the flipping mechanism, and then the above cutting operation is repeated to perform another thread cutting operation of the oil casing, and in the flipping process, the anti-blocking assembly drives the filter cloth to complete a lifting and flipping process, that is, when the three-jaw chuck rotates to 90 degrees, the filter cloth flips to the highest position, and when the three-jaw chuck rotates to 180 degrees, the filter cloth flips back to the lowest position, so that when the filter cloth flips to the highest position, the waste chips slide onto the annular support plate, and the backwash assembly is used to flush the filter cloth, driving the surface of the filter cloth to vibrate, so that the waste chips slide faster, and finally, with the operation of the cutting assembly, the cleaning assembly will be driven to work, driving the waste chips on the annular support plate along the waste outlet into the waste pipe, and then discharged.

[0021] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0022] 1. In the present invention, the three-jaw chuck and the oil casing can be driven to rotate 180 degrees under the action of the flip mechanism, so that the entire device can perform cutting operations on the two threads of the oil casing, realizing all-round cutting processing, without the need for frequent manual adjustment of the workpiece position, ensuring safety performance, and improving processing efficiency and processing quality.

[0023] 2. In the present invention, a spray assembly is used to spray coolant onto the cutting part, which can promptly take away the heat generated by cutting, reduce the temperature of the tool and the workpiece, reduce thermal deformation, and increase the service life of the tool. At the same time, the waste chips and coolant generated by cutting can be introduced into the water storage tank, and solid-liquid separation can be achieved under the action of the filter cloth, so that the coolant can be purified and is easy to recycle, which not only reduces production costs but also reduces environmental pollution. Since the cross-section of the filter cloth is designed to be V-shaped, the filtration area can be increased, the filtration efficiency can be improved, and the waste chips can be intercepted more effectively.

[0024] 3. In the present invention, a flipping mechanism provides power for the anti-blocking component. The driving gear rotates the driving turntable, which in turn drives the driven sliding frame, the first connecting rod, and the lifting rod to move up and down, driving the filter cloth to flip up and down. Thus, after the three-jaw chuck flips 180 degrees, the filter cloth completes a lifting and flipping process. That is, when the three-jaw chuck rotates to 90 degrees, the filter cloth flips to the highest position, and when the three-jaw chuck rotates to 180 degrees, the filter cloth flips back to the lowest position. Therefore, when the filter cloth flips to the highest position, the waste chips slide onto the annular support plate, and the backwashing component flushes water on the filter cloth, driving the surface of the filter cloth to vibrate, making the waste chips slide down faster, preventing the waste chips from accumulating and blocking the filter cloth, achieving the effect of automatically cleaning the filter cloth, without the need to repeatedly remove and clean, reducing the cleaning difficulty, saving manpower and time, and extending the service life of the filter cloth.

[0025] 4. In the present invention, the cleaning component can be linked with the rotating cylinder of the cutting component through a transmission belt, enabling the cleaning component to operate synchronously with the rotating cylinder, driving the scraping plate and the baffle to rotate. The scraping plate and the baffle scrape the waste chips that have fallen onto the annular support plate into the waste discharge port of the waste discharge pipe, realizing the automatic cleaning of the waste chips, reducing the workload and time of manual cleaning, and improving the continuous operation ability of the equipment.

[0043] In the present invention, a first mounting groove 23 is provided on one side of the annular support plate 11, and a second mounting groove 24 is provided on one side of the water storage tank 5, a waste pipe 14 is installed on the inner wall of the first mounting groove 23 and the inner wall of the second mounting groove 24, a waste outlet 25 is provided on one side of the top of the waste pipe 14, a cleaning component 15 for guiding waste debris into the waste outlet 25 is provided on the top of the annular support plate 11, an injection pipe and a waste pipe are respectively provided on one side of the water storage tank 5, and valves are installed at one end of the injection pipe and one end of the waste pipe.

[0044] In the present invention, the cleaning assembly 15 includes a through hole 1508 opened on one side of the bottom of the funnel 2 and one side of the top of the water storage tank 5, and the inner walls of the two through holes 1508 are rotatably connected to the transmission shaft 1501 through a sealed bearing, the top of the transmission shaft 1501 is rotatably connected to the top inner wall of the chassis 1, and the top of the outer wall of the transmission shaft 1501 and the top of the outer wall of the rotating drum 702 are both installed with a transmission wheel, and the two transmission wheels are connected to the transmission belt 1502, and the top inner wall of the water storage tank 5 is installed A bearing sleeve 1504 is installed, and a gear ring 1505 is installed on the outer wall of the bearing sleeve 1504. A transmission gear 1503 meshing with the gear ring 1505 is installed at the bottom of the transmission shaft 1501. Scraper plates 1507 distributed at equal distances are fixed to the bottom of the gear ring 1505, and the scraper plates 1507 are attached to the top surface of the annular support plate 11 and the circumferential inner wall of the water storage tank 5. One end of the scraper plate 1507 is fixed with a baffle 1506 attached to the top surface of the annular support plate 11. Figure 2 , Figure 3 , Figure 9 and Figure 10 As the cutting assembly 7 runs, the transmission belt 1502 drives the transmission shaft 1501 and the transmission gear 1503 to rotate. The meshing action of the transmission gear 1503 and the gear ring 1505 drives the scraper plate 1507 and the baffle plate 1506 to rotate, driving the waste chips on the annular support plate 11 along the waste outlet 25 into the waste pipe 14 and then discharged, thereby realizing the waste discharge function.

[0045] In the present invention, two partition plates 8 sequentially divide the interior of the chassis 1 into a first chamber, a second chamber, and a third chamber. Inspection covers are provided on one side of the first chamber and one side of the third chamber, and a box door is provided on one side of the second chamber. The water pump 301 is arranged inside the first chamber, the cutting assembly 7 and the mounting frame 9 are arranged inside the second chamber, and a controller 6 is arranged inside the third chamber. The controller 6 is electrically connected to the water pump 301, the driver 704, and the electric push rod 21. Refer to Figure 1 and Figure 2 shown, the controller 6 is used to control the operation of the entire cutting device.

[0046] A cutting method for the threaded gas-tight joint of oil casing, according to the cutting device for the threaded gas-tight joint of oil casing based on industrial machinery manufacturing, includes the following steps:

[0047] Step 1: Open the box door, place the oil casing in the three-jaw chuck 10, and make contact with the positioning bracket 22. Use the three-jaw chuck 10 to fixedly clamp the oil casing, and then close the box door;

[0048] Step 2: Control the cutting assembly 7 to work through the controller 6. Under the action of the driver 704, drive the cutting head 707 to rotate, and also gradually lower the height of the cutting head 707 under the action of the hydraulic cylinder 703, so as to perform one of the thread cutting operations on the oil casing;

[0049] Step 3: During the implementation of Step 2, synchronously control the spraying assembly 3 through the controller 6. Use the spraying assembly 3 to extract the coolant in the water storage tank 5 and spray it at the cutting position to perform a cooling and cleaning operation. The waste water and waste chips after cleaning will enter the water storage tank 5 along the funnel 2, and a solid-liquid filtration operation will be performed under the action of the filter cloth 13;

[0050] Step 4: After the above steps are completed, the cutting assembly 7 stops working and resets, and the spraying assembly 3 also stops working. Under the action of the flipping mechanism, drive the three-jaw chuck 10 and the oil casing to flip 180 degrees, and then repeat the above cutting operation to perform the other thread cutting operation on the oil casing. During the flipping process, cooperate with the anti-blocking assembly 16 to drive the filter cloth 13 to complete a lifting and flipping process, that is, when the three-jaw chuck 10 rotates to 90 degrees, the filter cloth 13 flips to the highest position, and when the three-jaw chuck 10 rotates to 180 degrees, the filter cloth 13 flips back to the lowest position. Thus, when the filter cloth 13 flips to the highest position, the waste chips slide onto the annular support plate 11, and cooperate with the backwashing assembly 12 to flush the filter cloth 13, driving the surface of the filter cloth 13 to vibrate, so that the waste chips slide off faster. Finally, as the cutting assembly 7 operates, it will drive the cleaning assembly 15 to work, driving the waste chips on the annular support plate 11 to enter the waste discharge pipe 14 along the waste discharge port 25 and then be discharged.

[0051] To sum up, the working principle of the present invention is as follows: The staff places the oil casing in the three-jaw chuck 10 and makes contact with the positioning bracket 22. The three-jaw chuck 10 is used to fixedly clamp the oil casing. The cutting assembly 7 is controlled by the controller 6 to work. Under the action of the driver 704, the rotating cylinder 702, the limiting strip 710, the rotating shaft 706, the mounting base 709 and the cutting head 707 are driven to rotate, and under the action of the hydraulic cylinder 703, the height of the lifting plate 705, the rotating shaft 706 and the cutting head 707 is gradually reduced, so as to perform one of the thread cutting operations on the oil casing;

[0052] During the cutting process, the staff synchronously controls the spraying assembly 3 to work through the controller 6. The coolant in the water storage tank 5 is pumped out by the water pump 301 and the water suction pipe 304 in the spraying assembly 3, and is sprayed on the cutting position along the drain pipe 302 and the nozzle 303 to perform the cooling and cleaning operation. The waste water and waste chips after cleaning will enter the water storage tank 5 along the funnel 2. At this time, the solid-liquid filtration operation is carried out by using the filter cloth 13;

[0053] Then, the staff stops the cutting assembly 7 from working and resets it, and the spraying assembly 3 also stops working. Under the action of the electric push rod 21 in the flipping mechanism, the L-shaped toothed plate 19 is driven to move, and the installation shaft 17, the three-jaw chuck 10 and the oil casing are driven to flip 180 degrees in cooperation with the meshing action of the L-shaped toothed plate 19 and the driving gear 20. Then, the cutting assembly 7 and the spraying assembly 3 are restarted to perform another thread cutting operation on the oil casing;

[0054] And during the flipping process, the driving turntable 1603 is driven to rotate through the meshing action of the first connecting gear 1602 and the second connecting gear 1606. Furthermore, the traction shaft 1608 drives the driven sliding frame 1604 to move up and down, driving the first connecting rod 1605, the second connecting rod 1609, the lifting rod 1607 and the movable seat 1610 to move up and down, driving the filter cloth 13 to complete a lifting and flipping process. That is, when the three-jaw chuck 10 rotates to 90 degrees, the filter cloth 13 flips to the highest position. When the three-jaw chuck 10 rotates to 180 degrees, the filter cloth 13 flips back to the lowest position. Thus, when the filter cloth 13 flips to the highest position, the waste chips slide onto the annular support plate 11 to remove the waste chips on the surface of the filter cloth. When the lifting rod 1607 moves upward, the water guide pipe 1201 and the piston 1202 in the backwashing assembly 12 are driven to move upward. The coolant in the water guide cylinder 1203 is squeezed by the piston 1202 and sprayed out along the water guide pipe 1201, the water guide holes 1207 and the spray holes 1208 to flush the filter cloth 13, driving the surface of the filter cloth 13 to vibrate, making the waste chips slide off faster and improving the cleaning effect;

[0055] Finally, with the operation of the cutting assembly 7, the cleaning assembly 15 will be driven to work, that is, the transmission belt 1502 is used to drive the transmission shaft 1501 and the transmission gear 1503 to rotate. The meshing of the transmission gear 1503 and the gear ring 1505 is used to drive the scraping plate 1507 and the baffle plate 1506 to rotate, driving the chips on the annular support plate 11 to enter the waste discharge pipe 14 along the waste discharge port 25 and then discharged, realizing the coordinated operation of each link in the whole cutting process of the oil casing thread type gas sealing buckle.

[0056] Combined with the current actual requirements, the above implementation manner adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
