Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] See also Figure 1-8A flange processing device comprises a base 1, an increasing block 2 and a cutting milling cutter 5. A mounting platform 9 is arranged above the base 1. A servo motor 20 is fixedly installed at the bottom of the mounting platform 9. A rotatable rotating shaft 26 is connected above the servo motor 20. A driving bevel gear 25 is fixedly installed on the outer wall of the rotating shaft 26. A mounting groove 21 is fixedly installed on the outer wall of the mounting platform 9. A rotatable threaded rod 23 is installed on the inner wall of the mounting groove 21. One end of the threaded rod 23 is fixedly connected to a driven bevel gear 24. A moving block is threadedly connected to the outer wall of the threaded rod 23. A placing plate 12 is fixedly connected to the top of the moving block. A retaining arc piece 13 is fixedly installed on the top surface of the placing plate 12. An electromagnet 8 is arranged above the mounting platform 9. A rotatable rotating toothed disc 14 is installed on the top surface of the base 1. The mounting platform 9 is fixedly installed on the top surface of the rotating toothed disc 14. A driving motor 28 is installed inside the base 1. A rotatable driving gear 15 is connected above the driving motor 28. The driving gear 15 meshes with the rotating toothed disc 14.

[0029] For further information, see Figure 1-3 A hydraulic rod 3 is fixedly installed above the heightening block 2, a mounting block 4 is fixedly installed above the hydraulic rod 3, a cutting milling cutter 5 is fixedly installed on one side of the mounting block 4, an electromagnet 8 is movably arranged at the bottom of the mounting block 4, a screw rod 6 is connected to the internal thread of the mounting block 4, the electromagnet 8 is fixedly installed at the bottom of the screw rod 6, and a fixed threaded sleeve 7 is connected to the part of the screw rod 6 located above the mounting block 4. By setting the electromagnet 8 and setting the electromagnet 8 fixedly installed below the screw rod 6, the position of the electromagnet 8 itself can be adjusted relative to the mounting block 4, so that the height of the mounting block 4 itself can be adjusted. During the adjustment, the height of the electromagnet 8 can be adjusted separately, so that the magnetic attraction of the electromagnet 8 to the iron after being energized can be adjusted by adjusting the position of the electromagnet 8, so that the user can adjust the height of the electromagnet 8 according to different situations, so that the electromagnet 8 can maintain a suitable magnetic attraction, so that the electromagnet 8 can be used more stably. At the same time, a retaining threaded sleeve 7 is provided on the outer wall of the screw rod 6, and the retaining threaded sleeve 7 is provided above the mounting block 4, so that the screw rod 6 cannot easily produce a reverse phenomenon without human power, and the height of the electromagnet 8 can be maintained.

[0030] For further information, see Figure 1-6A cavity 27 is provided inside the mounting platform 9, and the driving bevel gear 25, the rotating shaft 26, and the driven bevel gear 24 are all located inside the cavity 27. A support cover plate 10 is installed above the cavity 27. A moving groove 11 adapted to a moving block connected to the bottom of the placement plate 12 is provided through the outer wall of the support cover plate 10. By arranging the driving bevel gear 25, the rotating shaft 26, and the driven bevel gear 24 to be located inside the cavity 27 and installing the support cover plate 10 above the cavity 27, the driving bevel gear 25, the rotating shaft 26, and the driven bevel gear 24 are not easily damaged by the user during use, thereby increasing the safety of the device. The moving groove 11 is provided on the outer wall of the support cover plate 10 so that the placement plate 12 and the retaining arc piece 13 can move smoothly.

[0031] In addition, there are four mounting grooves 21, threaded rods 23, driven bevel gears 24, placement plates 12, and retaining arc pieces 13, which are distributed in a circular array on the mounting table 9. The four driven bevel gears 24 are meshed with the driving bevel gears 25 at the same time. By setting the placement plates 12 and the retaining arc pieces 13 to be four, the device can fix the flange from four directions, thereby achieving a better fixing effect of the flange. By setting the four driven bevel gears 24 to be meshed with the driving bevel gears 25 at the same time, the user can control the movement of the four placement plates 12 and the retaining arc pieces 13 at the same time through the driving bevel gears 25.

[0032] In addition, both the front and rear sides of the retaining arc piece 13 are designed as arc surfaces. By setting the front and rear sides of the retaining arc piece 13 as arc surfaces, the retaining arc piece 13 can fit with the inner and outer walls of the flange itself during the process of external clamping and internal supporting the flange, so that the device can better fix the flange. At the same time, the existence of the guide rod 16 can help the hydraulic rod 3 remain stable during the rising process.

[0033] In addition, by providing the protection box 22 and arranging the driven bevel gear 24, the driving bevel gear 25 and the rotating shaft 26 inside the protection box 22, the transmission of these parts is not easily affected by the debris generated by cutting, thereby increasing the stability of the device operation.

[0034] During specific implementation, the flange needs to be placed directly in the middle position of the top surface of the mounting table 9, and then the user needs to start the servo motor 20 to make the rotating shaft 26 start to rotate. After the rotating shaft 26 rotates, it will drive the driving bevel gear 25 to rotate, and the driving bevel gear 25 will mesh with the four driven bevel gears 24 at the same time. Therefore, the driven bevel gear 24 and the threaded rod 23 connected to the rear of the driven bevel gear 24 will rotate synchronously, and the moving block threadedly connected on the outer wall of the threaded rod 23 and the placement plate 12 above the moving block will be pushed due to the thrust of the thread, and the four placement plates 12 will drive the four retaining arc pieces 13 to move toward the top of the mounting table 9 at the same time. When the flange is moved to the middle position of the surface, the four movable retaining arc pieces 13 will clamp and fix the flange. After the fixing is completed, the user controls the hydraulic rod 3 and the cutting milling cutter 5 to move the milling cutter to the place where the flange needs to be cut. The drive motor 28 can be started during the movement. After the drive motor 28 is started, it will drive the drive gear 15 to rotate, and the rotating gear disc 14 is engaged with the drive gear 15. The mounting table 9 is fixedly installed above the rotating gear disc 14. Therefore, after the rotating gear disc 14 is driven to rotate by the driving gear 15, the mounting table 9 and the flange will also rotate accordingly, and the rotating flange contacts the milling cutter to complete the cutting process of the flange.

[0035] After completing the cutting of the inside of the flange, first move the placement plate 12 and the retaining arc piece 13 in the opposite direction to eliminate the clamping and fixing of the flange by the retaining arc piece 13. At this time, energize the electromagnet 8 to make the electromagnet 8 suck up the flange. After the flange is sucked up, the servo motor 20 controls the placement plate 12 and the retaining arc piece 13 to move toward the center position of the mounting table 9. After the placement plate 12 and the retaining arc piece 13 move to the limit state, cut off the power to the electromagnet 8 to make the flange fall. After the flange falls, the center position of the flange will surround the retaining arc piece 13 inside. At this time, start the servo motor 20 to move the four retaining arc pieces 13 outward. During the movement, the arc surface on the back of the retaining arc piece 13 will support the inner wall of the flange, so that the flange is supported and fixed on the periphery of the four retaining arc pieces 13. At this time, the user can cut the outer wall of the flange.

[0036] By setting up the electromagnet 8 and the retaining arc piece 13, the device can complete the internal support and external clamping of the flange, which is convenient for the device to cut the inner and outer walls of the flange. While improving the efficiency of the device in processing the flange, it also improves the stability of the device in fixing the flange, thereby ensuring the quality of flange processing.

[0037] It should be noted that the flange is mostly made of alloy steel and carbon steel, which can be successfully adsorbed by the electromagnet 8, and the specific size of the electromagnet 8 is not fixed and can be adjusted according to the specific needs of the user.

[0038] Embodiment 2

[0039] Based on Example 1, please refer to Figure 1-6 A flange processing device, wherein a support block 17 is fixedly installed above a base 1, a scraper block 18 is arranged above a retaining threaded sleeve 7, a detachable magnet block 19 is arranged inside the scraper block 18, and a collection box is arranged below the scraper block 18.

[0040] During specific implementation, when the user performs cutting processing on the flange, a large amount of iron filings will be generated from the flange raw material. Under normal conditions, the iron filings will fly everywhere, which is easy to affect the device and the user. In the present invention, the electromagnet 8 can be started during cutting. After starting, the electromagnet 8 will generate an adsorption force for iron, and the debris generated by the flange cutting is also iron. Therefore, after the electromagnet 8 is started, the debris generated by the flange cutting will be adsorbed by the electromagnet 8, and it can be collected after completing the cutting work on the inner wall or the outer wall of the flange to prevent the debris from affecting the operation of the device and the health of the user. At the same time, after the device stops running, the debris can be adsorbed by the magnet block 19 arranged above the scraper block 18, and then the magnet block 19 can be inserted horizontally into the scraper block 18, and then the magnet block 19 can be pulled upward. Since the specific shapes of the scraper block 18 and the magnet block 19 are comb-shaped blocks that are interlocked with each other, the debris adsorbed on the outer wall of the magnet block 19 will be scraped off by the scraper block 18 during the upward movement of the magnet block 19, and then fall into the collection box below.

[0041] By setting the electromagnet 8, the debris generated during the use of the device can be absorbed by the electromagnet 8, and the debris can be collected after the inner wall or outer wall of a flange is polished, so as to avoid the debris from affecting the operation of the device and increase the stability of the operation of the device. By setting the scraper block 18 and the magnet block 19, the device can more easily collect scattered debris.

[0042] For example 3, please refer to Figure 7-8, which is different from the first and second embodiments, the present embodiment does not have a servo motor 20, but a notch 29 is provided at the center position of the top of the rotating toothed disc 14. The shape of the notch 29 is not limited, but the center point of the notch 29 is on the axis of the rotating toothed disc 14. Another electromagnet 8 is fixed to the bottom of the notch 29, and an iron disc 31 that matches the shape of the electromagnet 8 in the notch 29 and can be plugged into the notch 29 is fixed to the bottom end of the rotating shaft 26. The top surface of the iron disc 31 is flush with the rotating toothed disc 14, and the bottom surface of the iron disc 31 is also in a fit state with the electromagnet 8. Further, the notch 29 is cylindrical , and an annular limiting groove is arranged on the side wall at the height of the iron disk 31 along the circumferential direction of the iron disk 31, the iron disk 31 can rotate in the annular limiting groove, and the upper and lower surfaces at the edge of the iron disk 31 are respectively in a state of abutment with the top and bottom surfaces of the annular limiting groove, and an annular rotating groove 30 is arranged on the top of the rotating gear disk 14, and the bottom of the mounting platform 9 is inserted in the rotating groove 30, and the mounting platform 9 can rotate along the contour of the rotating groove 30, and an electromagnet 8 is also installed in the rotating groove 30, and the mounting platform 9 is also made of magnetic metal material, and a switch is arranged to control the on and off of the three electromagnets 8.

[0043] When it is necessary to drive the rotating shaft 26 to rotate, the electromagnet 8 in the recess 29 is energized. At this time, the electromagnet 8 in the rotating groove 30 is de-energized, and the screw rod 6 is rotated to make the electromagnet 8 at the bottom end thereof abut against the top surface of the mounting platform 9. At this time, the electromagnet 8 at the bottom end of the screw rod 6 is energized. The mounting platform 9 is a magnetic metal. Therefore, at this time, the mounting platform 9 and the electromagnet 8 at the bottom end of the screw rod 6 are adsorbed and fixed. The rotation of the rotating toothed disk 14 can drive the iron disk 31 and the rotating shaft 26 to rotate. At this time, the mounting platform 9 does not rotate, and the flange can be fixed. When the angle of the mounting platform 9 needs to be adjusted after fixation, the electromagnet 8 in the recess 29 can be de-energized, and the screw rod 6 can be rotated to make the electromagnet at the bottom end of the screw rod 6 detach from the mounting platform 9. At this time, the rotating toothed disk 14 can be used to drive the mounting platform 9 to rotate and adjust the angle of the mounting platform 9, and the rotating shaft 26 will not rotate at this time.

[0044] Working principle: the flange needs to be placed directly in the middle of the top surface of the mounting table 9, and then the user needs to start the servo motor 20 to make the rotating shaft 26 start to rotate. After the rotating shaft 26 rotates, it will drive the driving bevel gear 25 to rotate, and the driving bevel gear 25 will mesh with the four driven bevel gears 24 at the same time. Therefore, the driven bevel gear 24 and the threaded rod 23 connected to the rear of the driven bevel gear 24 will rotate synchronously, and the moving block threadedly connected on the outer wall of the threaded rod 23 and the placement plate 12 above the moving block will be pushed due to the thrust of the thread, and the four placement plates 12 will drive the four retaining arc pieces 13 to the top surface of the mounting table 9 at the same time. The intermediate position moves, and the four movable retaining arc pieces 13 will clamp and fix the flange. After the fixing is completed, the user controls the hydraulic rod 3 and the cutting milling cutter 5 to move the milling cutter to the place where the flange needs to be cut. The drive motor 28 can be started during the movement. After the drive motor 28 is started, it will drive the drive gear 15 to rotate, and the rotating gear disc 14 is engaged with the drive gear 15. The mounting platform 9 is fixedly installed above the rotating gear disc 14. Therefore, after the rotating gear disc 14 is driven to rotate by the driving gear 15, the mounting platform 9 and the flange will also rotate accordingly, and the rotating flange contacts the milling cutter to complete the cutting process of the flange.

[0045] After completing the cutting of the inside of the flange, first move the placement plate 12 and the retaining arc piece 13 in the opposite direction to eliminate the clamping and fixing of the flange by the retaining arc piece 13. At this time, energize the electromagnet 8 to make the electromagnet 8 suck up the flange. After the flange is sucked up, the servo motor 20 controls the placement plate 12 and the retaining arc piece 13 to move toward the center position of the mounting table 9. After the placement plate 12 and the retaining arc piece 13 move to the limit state, cut off the power to the electromagnet 8 to make the flange fall. After the flange falls, the center position of the flange will surround the retaining arc piece 13 inside. At this time, start the servo motor 20 to move the four retaining arc pieces 13 outward. During the movement, the arc surface on the back of the retaining arc piece 13 will support the inner wall of the flange, so that the flange is supported and fixed on the periphery of the four retaining arc pieces 13. At this time, the user can cut the outer wall of the flange.

[0046] During the process of cutting the flange by the user, a large amount of iron filings will be generated from the flange raw material. Under normal conditions, the iron filings will fly everywhere, which is easy to affect the device and the user. In the present invention, the electromagnet 8 can be started during cutting. After starting, the electromagnet 8 will generate an adsorption force for iron, and the debris generated by the flange cutting is also iron. Therefore, after the electromagnet 8 is started, the debris generated by the flange cutting will be adsorbed by the electromagnet 8, and can be collected after completing the cutting work on the inner wall or the outer wall of the flange to prevent the debris from affecting the operation of the device and the health of the user. At the same time, after the device stops running, the debris can be adsorbed by the magnet block 19 arranged above the scraper block 18, and then the magnet block 19 can be inserted horizontally into the scraper block 18, and then the magnet block 19 can be pulled upward. Since the specific shapes of the scraper block 18 and the magnet block 19 are comb-shaped blocks that are interlocked with each other, during the upward movement of the magnet block 19, the debris adsorbed on the outer wall of the magnet block 19 will be scraped off by the scraper block 18 and then fall into the collection box below.

[0047] By setting up the electromagnet 8 and the retaining arc piece 13, the device can complete the internal support and external clamping of the flange, which is convenient for the device to cut the inner and outer walls of the flange. While improving the efficiency of the device in processing the flange, it also improves the stability of the device in fixing the flange, thereby ensuring the quality of flange processing.

[0048] By setting the electromagnet 8, the debris generated during the use of the device can be absorbed by the electromagnet 8, and the debris can be collected after the inner wall or outer wall of a flange is polished, so as to avoid the debris from affecting the operation of the device and increase the stability of the operation of the device. By setting the scraper block 18 and the magnet block 19, the device can more easily collect scattered debris.
