Description

Technical Field

[0001] The invention relates to the technical field of steel pipe processing equipment, in particular to a bending and cutting machine for cold-processing refined steel pipes. Background Art

[0002] Refined steel pipes are usually hollow, which allows them to be used for the transportation, storage or as structural components of solid-liquid fluids, liquids or gases. They are widely used in industries, construction, petroleum, chemical industry and other fields. These pipes can be used to transport oil, natural gas, water, steam, etc., and can also be used as pipe connectors. Cold processing refers to the processing of materials at room temperature. Refined steel pipes are cold-processed, bent and cut to a suitable length so that they can better adapt to the installation space and layout after processing, thereby changing the direction of the fluid or gas transported in the refined steel pipe.

[0003] During the bending process of refined steel pipes, the inner side of the steel pipe is compressed and the outer side is stretched, resulting in uneven force on the inner and outer sides of the bend. As a result, the inner side of the steel pipe is prone to internal flattening at the bend. At the same time, when the steel pipe is bent during cold processing, the stress at the bend is relatively large. When this stress reaches a certain level, it is easy to cause cracks at the bending point of the steel pipe. Once cracks appear inside the steel pipe, it is not only not conducive to the equipment's detection, but also brings inconvenience to the quality inspection and use of the steel pipe, and also reduces the bending quality of the steel pipe.

[0004] Therefore, a bending and cutting machine for cold-processing refined steel pipes is proposed. Summary of the invention

[0018] The present invention provides a bending and cutting machine for cold-processed refined steel pipes, which has the following technical points and beneficial effects:

[0019] 1. The present invention designs expansion strips, magnetic filter plates, oil pumps and other devices, and detects cracks generated in refined steel pipes and metal debris falling off the cracks through an ultrasonic flaw detector. After the bending process of the refined steel pipe is completed, the servo motor is reversed to allow the oil pump to suck the heat dissipation oil in the refined steel pipe, and then the expansion strip is pulled out from one end of the refined steel pipe. At this time, the other end of the expansion strip will clean the metal debris generated by the cracks in the refined steel pipe, and the metal debris is magnetically intercepted by the magnetic filter plate and the metal debris on the magnetic end surface of the other end of the expansion strip is collected, and then the amount of metal debris collected on the magnetic filter plate and the magnetic end surface is used to assist in verifying the degree of cracks in the refined steel pipe, so as to facilitate the quality inspection of the refined steel pipe after bending.

[0020] 2. The present invention designs expansion strips, limiting expansion plates, omnidirectional wheels and other devices. When the refined steel pipe is bent, the refined steel pipe is embedded and slid in the omnidirectional wheel to provide a bending distance, thereby preventing the refined steel pipe from being unevenly stressed and flattened when bent due to the large pulling force at the rear end of the refined steel pipe. After the expansion strip is pushed to the other end of the refined steel pipe by the heat dissipation oil, the oil pump stops pumping the heat dissipation oil, and the heat dissipation oil is sealed inside the refined steel pipe by the expansion strip and the oil pump. The heat generated at the bending point of the refined steel pipe is conducted away by the heat dissipation oil, thereby preventing the refined steel pipe from being locally overheated and deformed when bent. At the same time, the stress generated during bending is evenly transmitted and dispersed, thereby reducing the risk of the refined steel pipe being flattened and cracks caused by local stress concentration during bending, thereby improving the quality of the refined steel pipe after bending.

[0021] 3. The present invention designs an oil pump, a heat dissipation oil barrel, a hydraulic telescopic rod and other devices, and operates the oil pump through a servo motor. While the expansion strip is extracted from the refined steel pipe, the heat dissipation oil is transported to the hydraulic telescopic rod through the oil pipe. The heat dissipation oil is filled into the hydraulic telescopic rod, thereby pushing the driving machine to slide on the transmission conversion box. At this time, the transmission shaft on one side of the driving machine slides in the transmission conversion box to cancel the transmission connection between the transmission component inside the driving machine and the bending transmission machine and the transmission box, and at the same time, the transmission component is connected to the transmission shaft, thereby providing power to the driving machine through the transmission shaft, and the driving machine drives the electric saw to operate. At this time, the electric saw moves in the cutting groove under the push of the hydraulic telescopic rod, and then cuts the refined steel pipe.

[0022] 4. The present invention designs expansion strips, magnetic end faces, oil pumps and other devices. When the refined steel pipe is filled with heat dissipation oil, the expansion strip fits against the inner wall of the refined steel pipe, so that one end of the expansion strip rubs and cleans the inner wall of the refined steel pipe, and the cleaned metal debris and dust are adsorbed and attached to the magnetic end face on one side of the expansion strip and the grinding cotton ring on the outer circle of the magnetic end face, thereby cleaning the inner wall of the refined steel pipe. When the refined steel pipe is bent and the expansion strip is pulled out of the refined steel pipe, part of the heat dissipation oil remaining on the inner wall of the refined steel pipe will form a protective film to isolate air and moisture, thereby reducing the possibility of rust and corrosion of the refined steel pipe during storage after processing.

DETAILED DESCRIPTION

[0037] See also Figures 1 to 12 The present invention provides a technical solution for a bending and cutting machine for cold-processed refined steel pipes:

[0038] A bending and cutting machine for cold-processing refined steel pipes, comprising a processing table 1 and a limiting slide rail 4 fixedly installed above the processing table 1, and a limiting slide plate 15 is slidably installed on the inner side of the limiting slide rail 4, and a heat dissipation oil barrel 16 is fixedly installed inside the processing table 1, a fixed base 6 is provided on one side of the limiting slide rail 4, and the fixed base 6 is fixedly connected to the processing table 1, a clamping table 7 is provided on one side of the fixed base 6, and the clamping table 7 is fixedly connected to the processing table 1, a sliding clamping block 701 is provided between the clamping table 7 and the fixed base 6, and the sliding clamping block 701 is movably connected to the clamping table 7, both sides of the upper side of the limiting slide rail 4 are fixedly installed with limiting plates 5, and an omnidirectional wheel 501 is embedded and installed inside the limiting plate 5 on one side;

[0039] One side of the limiting slide plate 15 is fixedly connected to a limiting expansion plate 1501, and one side of the limiting expansion plate 1501 is movably connected with a plurality of magnetic expansion clamps 1502. A refined steel pipe 11 is provided above the limiting slide rail 4, and the refined steel pipe 11 is embedded and installed between the omnidirectional wheel 501 and the magnetic expansion clamp 1502. The inner side of the refined steel pipe 11 is movably connected with an expansion soft strip 1101, and both sides of the expansion soft strip 1101 are provided with magnetic end faces 1102. One side of the limiting expansion plate 1501 is provided with A sealing rubber 1503 is provided, and the sealing rubber 1503 is sealed and fitted with the limiting expansion plate 1501 and the magnetic expansion clamp 1502. A magnetic filter plate 1505 is embedded and installed on the inner side of the limiting expansion plate 1501. An oil pump 19 is provided on one side of the heat dissipation oil barrel 16, and the oil pump 19 is fixedly connected to the processing table 1. Oil pipes 14 are respectively provided on both sides of the heat dissipation oil barrel 16, and the limiting slide plate 15 and the oil pump 19 are connected to the heat dissipation oil barrel 16 through the oil pipe 14 on one side;

[0040] As an embodiment of the present invention, Figures 1 to 12 As shown, an oil hole 1504 corresponding to the magnetic expansion clamp 1502 is provided on the inner side of the limit expansion plate 1501, a tension spring 1506 is provided on one side of the magnetic expansion clamp 1502, and the two sides of the tension spring 1506 are respectively fixedly connected to the magnetic expansion clamp 1502 and the limit expansion plate 1501;

[0041] During operation, the limiting slide plate 15 is installed and used through the limiting slide rail 4. Before the refined steel pipe 11 is bent, the limiting slide plate 15 is initially on the side of the limiting plate 5 close to the console 3, and the expansion soft strip 1101 is located in the middle of the magnetic expansion clamp 1502 to block the limiting expansion plate 1501. At this time, the heat dissipation oil in the oil pipe 14 on one side of the limiting slide plate 15 is full. When the refined steel pipe 11 is placed between the omnidirectional wheel 501 and the magnetic expansion clamp 1502, one end of the refined steel pipe 11 is inserted into the outside of the magnetic expansion clamp 1502. At this time, the magnetic expansion clamp 1502 fits the inner wall of the refined steel pipe 11 under the tension and magnetic attraction of the tension spring 1506. Then, one end of the refined steel pipe 11 is expanded and clamped. When the servo motor 18 drives the oil pump 19 to operate, the heat dissipation oil in the oil pipe 14 connected to the hydraulic telescopic rod 21 and the heat dissipation oil barrel 16 is first pumped into the refined steel pipe 11 through the pumping of the oil pump 19, and the refined steel pipe 11 expanded and clamped on one side of the limit expansion plate 1501 is fitted and sealed through the sealing rubber 1503. When the heat dissipation oil is pumped into the refined steel pipe 11, due to the magnetic attraction between the magnetic end face 1102 and the magnetic filter plate 1505, part of the heat dissipation oil will enter the limit expansion plate 1501 through the oil hole 1504, pushing the magnetic expansion clamp 1502 to expand so as to improve the control of the refined steel pipe 11 The expansion clamping stability will cause the sealing rubber 1503 to expand to a certain extent, thereby improving the sealing effect of the sealing rubber 1503 on the refined steel pipe 11, and the expansion strip 1101 cancels the magnetic blocking state of the magnetic end face 1102 on the magnetic filter plate 1505 through the push of the heat dissipation oil. At the same time, the expansion strip 1101 is pushed to the other end of the refined steel pipe 11 and the oil pump 19 is stopped to pump the heat dissipation oil, so that the heat dissipation oil is filled in the refined steel pipe 11, and the heat dissipation oil is blocked in the refined steel pipe 11 by the expansion strip 1101 and the oil pump 19. When the refined steel pipe 11 is filled with heat dissipation oil, the expansion strip 1101 and the refined steel pipe 1 1, so that one end of the expansion strip 1101 rubs and cleans the inner wall of the refined steel pipe 11, and the cleaned impurities are adsorbed and attached to the magnetic end face 1102 on one side of the expansion strip 1101 and the grinding cotton ring on the outer ring of the magnetic end face 1102, thereby cleaning the inner wall of the refined steel pipe 11. Since the expansion strip 1101 always remains in an expanded state, when the expansion strip 1101 is pushed at the bend of the refined steel pipe 11, it always remains in contact with the inner wall, thereby preventing the expansion strip 1101 from generating a gap at the bend of the refined steel pipe 11, so that the impurities cleaned on one side of the expansion strip 1101 enter the oil, thereby preventing the impurities in the heat dissipation oil from affecting the detection quality of ultrasonic flaw detection;

[0042] When the refined steel pipe 11 is transported to the middle of the fixed base 6 and the clamping platform 7 through the omnidirectional wheel 501 on the inner side of the limiting plate 5, the refined steel pipe 11 is fitted with the fixed base 6 through the sliding clamping block 701 on the clamping platform 7, thereby improving the flaw detection effect of the ultrasonic flaw detector in the fixed base 6. At the same time, the refined steel pipe 11 acts as a side end fulcrum to assist in bending when bending. Since the refined steel pipe 11 is filled with heat dissipation oil, when the refined steel pipe 11 is bent between the bending wheel 902 and the bending platform 8, the refined steel pipe 11 is bent by the omnidirectional wheel 501 is embedded and slided to provide a bending distance, thereby preventing the situation where the pulling force at the rear end of the refined steel pipe 11 is too large, causing the refined steel pipe 11 to be unevenly stressed and flattened when bending. The heat generated at the bending point of the refined steel pipe 11 is taken away and conducted by the heat dissipation oil, thereby preventing the refined steel pipe 11 from being locally overheated and deformed when bending. At the same time, the stress generated during bending is evenly transmitted and dispersed, thereby reducing the risk of the refined steel pipe 11 being flattened and the risk of cracks caused by local stress concentration during bending, thereby improving the quality of the refined steel pipe 11 after bending.

[0043] As an embodiment of the present invention, Figures 1 to 8 As shown, an ultrasonic flaw detector is provided on the inner side of the fixed base 6, and the ultrasonic flaw detector is clamped and arranged in contact with the refined steel pipe 11 by the sliding clamp block 701. A mounting groove is provided on one side of the fixed base 6, and a bending table 8 is embedded and installed in the mounting groove.

[0044] During operation, the refined steel pipe 11 after bending is inspected by the ultrasonic flaw detector in the fixed base 6. Since the expansion soft strip 1101 cleans the inner wall when the heat dissipation oil is filled into the refined steel pipe 11, the interference of impurities in the heat dissipation oil in the refined steel pipe 11 on the flaw detection is reduced. When the refined steel pipe 11 is bent and cracks are generated, the cracks and metal debris falling off the cracks are detected by the ultrasonic flaw detector to detect the degree of cracks in the refined steel pipe 11. After the bending of the refined steel pipe 11 is completed, the servo motor 18 is reversed to make the oil pump 19 suck the heat dissipation oil in the refined steel pipe 11. Conversely, the expansion soft strip 1101 is drawn out from one end of the refined steel pipe 11. At this time, the other end of the expansion soft strip 1101 will be on the refined steel pipe 11. The metal debris generated by the cracks in the steel pipe 11 is cleaned. When the expansion strip 1101 is pulled out from the refined steel pipe 11 and sealed with the limit expansion plate 1501, the metal debris is magnetically intercepted by the magnetic filter plate 1505 and the metal debris on the magnetic end face 1102 at the other end of the expansion strip 1101 is collected, thereby assisting in verifying the degree of cracks in the refined steel pipe 11. Since the expansion strip 1101 always remains in an expanded state, when the expansion strip 1101 is pulled out at the bend of the refined steel pipe 11, it always remains in contact with the inner wall to prevent the cracked metal debris from sliding from the gap between the expansion strip 1101 and the refined steel pipe 11 into the magnetic end face 1102 on one side of the expansion strip 1101, thereby preventing misjudgment of the auxiliary inspection of the refined steel pipe 11.

[0045] As an embodiment of the present invention, Figure 4 and Fig.11 As shown, a voltage stabilizing plate 1601 is movably mounted inside the heat dissipation oil barrel 16, a sealing cover 1602 is mounted above the heat dissipation oil barrel 16, and a spring rod 1603 connected to the voltage stabilizing plate 1601 is mounted below the sealing cover 1602, a reel 20 is provided on one side of the inner part of the processing table 1, and the oil pipe 14 on one side of the heat dissipation oil barrel 16 surrounds the outer side of the reel 20 and is fixedly connected to the limiting slide plate 15;

[0046] During operation, when the oil pump 19 pumps the heat dissipation oil into the refined steel pipe 11 through the servo motor 18, the oil pipe 14 is wound and rotated by the reel 20 to pump and connect the heat dissipation oil to the refined steel pipes 11 of different lengths. When the magnetic expansion clamp 1502 cancels the expansion clamping of the refined steel pipe 11 and separates, the oil pipe 14 is wound and retracted by rotating the reel 20, and the voltage stabilizing plate 1601 is pressed down by the elastic potential energy of the spring rod 1603. Furthermore, when the heat dissipation oil in the heat dissipation oil barrel 16 is transported to the refined steel pipe 11 or the hydraulic telescopic rod 21 by the operation of the oil pump 19, the hydraulic transmission effect is improved. Since the elastic potential energy of the spring rod 1603 is not enough to hydraulically transport the heat dissipation oil in the heat dissipation oil barrel 16 to the hydraulic telescopic rod 21 through the voltage stabilizing plate 1601, the refined steel pipe 11 is prevented from bending. When the heat dissipation oil is transported to the hydraulic telescopic rod 21 by the operation of the oil pump 19, similarly, to prevent the heat dissipation oil from being transported to the limit expansion plate 1501, the expansion strip 1101 cancels the blockage of the limit expansion plate 1501, wherein the length of the oil pipe 14 connecting the heat dissipation oil barrel 16 and the hydraulic telescopic rod 21 is equal to or equal to the length of the connection between the heat dissipation oil barrel 16 and the limit slide plate 15. When the heat dissipation oil needs to be supplemented, the expansion strip 1101 is removed from the limit expansion plate 1501, and the limit expansion plate 1501 is docked with the supplemented heat dissipation oil. The servo motor 18 operates the oil pump 19 to suck the supplemented heat dissipation oil into the heat dissipation oil barrel 16 for supplementary use, and the sealing cover 1602 is used to facilitate the cleaning or maintenance of the heat dissipation oil barrel 16.

[0048] During operation, the servo motor 18 provides power for the transmission conversion box 1703, and the power is transmitted to the bending transmission machine 1704 and the transmission box 1705 through the transmission components in the transmission conversion box 1703, and the bending transmission machine 1704 and the transmission box 1705 provide power to the bending transmission shaft 1002 and the transmission wheel respectively, so that the bending transmission shaft 1002 drives the bending base 10 to rotate on the fixed plate 17, thereby bending the refined steel pipe 11, and making the transmission belt 1701 reciprocate on the fixed plate 17 through the transmission wheel, and secondly, the balance bar provided under the bending base 10 is limited by the balance groove 1702, thereby improving the stability of the bending base 10 during bending.

[0051] During operation, when the bending base 10 is rotated by the bending transmission shaft 1002 to bend the refined steel pipe 11, the transmission fixed block 1001 is connected to the transmission belt 1701, so that the transmission belt 1701 pulls the transmission fixed block 1001 to rotate synchronously, thereby reducing the torque of the bending transmission shaft 1002 on the bending base 10, and improving the service life of the bending equipment. The distance of the bending slide 9 on the bending base 10 is adjusted and fixed by rotating the turning handle 1003, thereby adjusting the bending wheel The degree of fit between 902 and the refined steel pipe 11 when bending, and the installation of the bending table 8 through the installation groove and the installation of the bending plate 901 on the bending slide 9, are convenient for replacing different bending equipment for use. When the refined steel pipe 11 is bent between the bending wheel 902 and the bending table 8, the bending table 8 is fixed by the fixing plug 801, and the bending plate 901 is fixed by the fixing rod under the bending plate 901, which is convenient for the installation and use of the bending table 8 and the bending plate 901.

[0052] As an embodiment of the present invention, Figures 4 to 6 As shown, a hydraulic telescopic rod 21 is fixedly connected to one side of the transmission conversion box 1703, and the hydraulic telescopic rod 21 is connected to the heat dissipation oil barrel 16 through the oil pipe 14, a driving machine 22 is provided on one side of the hydraulic telescopic rod 21, and the driving machine 22 is slidably connected on the transmission conversion box 1703 through the hydraulic telescopic rod 21, a cutting groove 12 is provided on one side of the limiting slide rail 4, and the cutting groove 12 is connected to the processing table 1, and an electric saw 2201 is provided above the driving machine 22, and the electric saw 2201 is movably arranged in the cutting groove 12 through the driving machine 22;

[0053] During operation, when the remaining length of the refined steel pipe 11 after bending is too long to be used, the servo motor 18 is used to operate the oil pump 19 to transport the heat dissipation oil from the heat dissipation oil barrel 16 to the hydraulic telescopic rod 21 through the oil pipe 14. The heat dissipation oil is filled into the hydraulic telescopic rod 21, thereby pushing the driving machine 22 to slide on the transmission conversion box 1703. At this time, the transmission shaft on one side of the driving machine 22 slides in the transmission conversion box 1703 to cancel the transmission connection between the transmission component inside it and the bending transmission machine 1704 and the transmission box 1705, and at the same time, the transmission component is connected to the transmission shaft (the working process is as follows: By changing the position of the driving machine 22, the transmission component can switch between different transmission paths. The transmission working principle is similar to the clutch device in some adjustable transmission ratio transmissions or mechanical transmission systems. It is an existing and mature technical means and is common knowledge for those skilled in the art. In this technical solution, only this technical means is used and will not be elaborated on here). The driving machine 22 is then powered by the transmission shaft, and the electric saw 2201 is driven by the driving machine 22. At this time, the electric saw 2201 moves in the cutting groove 12 under the push of the hydraulic telescopic rod 21, and then the refined steel pipe 11 is cut.

[0054] As an embodiment of the present invention, Figures 1 to 6 As shown, a power supply box 101 is fixedly connected to the other side of the interior of the processing table 1, and a power supply interface 102 is electrically connected to one side of the power supply box 101. A placement rack 103 for storing the refined steel pipe 11 is respectively provided on both sides of the reel 20, and the placement rack 103 is fixedly connected to the processing table 1. A universal wheel 2 is fixedly connected to the bottom of the processing table 1, and a cable tube 13 is fixedly connected to the top of the processing table 1. A control console 3 is fixedly connected to one side of the processing table 1. The control console 3 is connected to the ultrasonic flaw detector signal in the fixed base 6 through the cable tube 13 on the processing table 1, and the control console 3 is connected to the omnidirectional wheel 501 and the servo motor 18 signal. The power supply box 101 is electrically connected to the control console 3, the omnidirectional wheel 501, the servo motor 18 and the ultrasonic flaw detector in the fixed base 6;

[0055] When working, it is connected to an external power source through the power interface 102, and the power line and signal line are wrapped and protected by the cable tube 13, and the power is transmitted to the power box 101 through the power line, and the current is integrated and distributed through the power box 101, so as to power the control console 3, the servo motor 18 and the ultrasonic flaw detector in the fixed base 6. When in use, the control console 3 receives and transmits signals, so as to control the servo motor 18 and the ultrasonic flaw detector in the fixed base 6. Secondly, through the universal The wheels 2 facilitate moving the processing table 1 to the working area to perform cold processing and bending on the refined steel pipe 11. When the bending angle of the refined steel pipe 11 needs to be adjusted, the operation of the omnidirectional wheel 501 is controlled by the control console 3, and the refined steel pipe 11 is rotated inside it by the omnidirectional wheel 501, so as to perform multi-angle continuous bending on the refined steel pipe 11. The placement rack 103 is tilted to place the refined steel pipe 11 while preventing the refined steel pipe 11 from falling out of the placement rack 103 when the processing table 1 is moved.

[0056] Working principle: When in use, the processing table 1 is moved to the working area by the universal wheel 2 to perform cold processing and bending on the refined steel pipe 11. When the bending angle of the refined steel pipe 11 needs to be adjusted, the operation of the omnidirectional wheel 501 is controlled by the control console 3, and the refined steel pipe 11 is rotated inside the omnidirectional wheel 501, so as to perform multi-angle continuous bending on the refined steel pipe 11.

[0057] The servo motor 18 provides power to the transmission conversion box 1703, and the power is transmitted to the bending transmission machine 1704 and the transmission box 1705 through the transmission components in the transmission conversion box 1703, and the bending transmission machine 1704 and the transmission box 1705 respectively provide power to the bending transmission shaft 1002 and the transmission wheel, so that the bending transmission shaft 1002 drives the bending base 10 to rotate on the fixed plate 17, and the transmission belt 1701 reciprocates on the fixed plate 17 through the transmission wheel. 02 is rotated to bend the refined steel pipe 11, and the transmission fixed block 1001 is pulled by the transmission belt 1701 to rotate synchronously, thereby reducing the torque of the bending transmission shaft 1002 on the bending base 10, and improving the service life of the bending equipment. The distance of the bending slide 9 on the bending base 10 is adjusted and fixed by rotating the handle 1003, thereby adjusting the degree of fit between the bending wheel 902 and the refined steel pipe 11 during bending. At the same time, the installation of the bending table 8 and the installation of the bending slide 9 on the bending plate 901 are carried out through the installation groove, so as to facilitate the replacement of different bending equipment for use;

[0058] When the refined steel pipe 11 is placed between the omnidirectional wheel 501 and the magnetic expansion clamp 1502, one end of the refined steel pipe 11 is inserted into the outside of the magnetic expansion clamp 1502. At this time, the magnetic expansion clamp 1502 fits with the inner wall of the refined steel pipe 11 under the tension of the tension spring 1506 and the magnetic attraction, and then expands and clamps one end of the refined steel pipe 11. When the servo motor 18 drives the oil pump 19 to operate, the heat dissipation oil is pumped into the refined steel pipe 11 by the oil pump 19, and the refined steel pipe 11 expanded and clamped on one side of the limit expansion plate 1501 is fit and sealed by the sealing rubber 1503. The expansion soft strip 1101 cancels the magnetic end face 1102 from the magnetic attraction through the push of the heat dissipation oil. The filter plate 1505 is in a magnetic sealing state, and the expansion strip 1101 is pushed to the other end of the refined steel pipe 11, and then the oil pump 19 stops pumping the heat dissipation oil. The heat dissipation oil is sealed inside the refined steel pipe 11 through the expansion strip 1101 and the oil pump 19. When the refined steel pipe 11 is filled with heat dissipation oil, the expansion strip 1101 is attached to the inner wall of the refined steel pipe 11, so that one end of the expansion strip 1101 rubs and cleans the inner wall of the refined steel pipe 11, and the cleaned metal debris and dust are adsorbed and attached to the magnetic end face 1102 on one side of the expansion strip 1101 and the grinding cotton ring on the outer ring of the magnetic end face 1102, thereby cleaning the inner wall of the refined steel pipe 11;

[0059] When the refined steel pipe 11 is bent and cracks are generated, the cracks and metal debris falling off the cracks are detected by an ultrasonic flaw detector. After the refined steel pipe 11 is bent, the servo motor 18 is reversed to allow the oil pump 19 to suck the heat dissipation oil in the refined steel pipe 11. Similarly, the expansion strip 1101 is then pulled out from one end of the refined steel pipe 11. At this time, the other end of the expansion strip 1101 will clean the metal debris generated by the cracks in the refined steel pipe 11. When the expansion strip 1101 is pulled out of the refined steel pipe 11 and is sealed with the limiting expansion plate 1501, the metal debris is magnetically intercepted by the magnetic filter plate 1505 and the metal debris on the magnetic end face 1102 at the other end of the expansion strip 1101 is collected. Then, the amount of metal debris collected on the magnetic filter plate 1505 and the magnetic end face 1102 is used to assist in verifying the degree of cracks in the refined steel pipe 11.

[0060] The sliding clamp 701 plays a role of assisting the bending of the refined steel pipe 11 by the side end support when bending. When the refined steel pipe 11 is bent between the bending wheel 902 and the bending table 8, the refined steel pipe 11 is bent by sliding in the omnidirectional wheel 501 to provide a bending distance, so as to prevent the situation that the refined steel pipe 11 is unevenly stressed and flattened when bending due to the large pulling force at the rear end of the refined steel pipe 11. The heat generated at the bending point of the refined steel pipe 11 is taken away and conducted by the heat dissipation oil, thereby preventing the refined steel pipe 11 from being locally overheated and deformed when bending, and at the same time, the stress generated during bending is evenly transmitted and dispersed, thereby reducing the risk of cracks caused by the internal flattening and local stress concentration of the refined steel pipe 11 during bending, and improving the quality of the refined steel pipe 11 after bending;

[0061] When the refined steel pipe 11 needs to be cut, the oil pump 19 is operated by the servo motor 18, and the heat dissipation oil is transported to the hydraulic telescopic rod 21 through the oil pipe 14. The heat dissipation oil is filled in the hydraulic telescopic rod 21, and then the driving machine 22 is pushed to slide on the transmission conversion box 1703. At this time, the transmission shaft on one side of the driving machine 22 slides in the transmission conversion box 1703 to cancel the transmission connection between the internal transmission component and the bending transmission machine 1704 and the transmission box 1705, and at the same time, the transmission component is connected to the transmission shaft, and then the driving machine 22 is powered by the transmission shaft, and the electric saw 2201 is driven by the driving machine 22 to operate. At this time, the electric saw 2201 moves in the cutting groove 12 under the push of the hydraulic telescopic rod 21, and then the refined steel pipe 11 is cut.

[0062] The voltage stabilizing plate 1601 is pressed down by the elastic potential energy of the spring rod 1603, and then when the cooling oil in the cooling oil barrel 16 is transported to the refined steel pipe 11 or the hydraulic telescopic rod 21 through the operation of the oil pump 19, the hydraulic transportation effect is improved. When the cooling oil needs to be supplemented, the expansion strip 1101 is removed from the limiting expansion plate 1501, and the limiting expansion plate 1501 is connected to the supplemented cooling oil. The servo motor 18 operates the oil pump 19 to suck the supplemented cooling oil into the cooling oil barrel 16 for supplementary use.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
