DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figures 1 to 7 As shown, an automatic flat-end machine for stainless steel pipes comprises a base plate 1, a gear ring 3 is fixedly mounted on the top of the base plate 1, and a cutting machine 37 is rotatably mounted on the inner surface of the gear ring 3; it also comprises a flat-end mechanism for cleaning burrs on the end of the stainless steel pipe; the flat-end mechanism comprises a vertical plate 5, a sixth motor 501 is fixedly mounted on one side of the vertical plate 5, the output shaft of the sixth motor 501 is fixedly connected to a disc 51, two chutes 52 are provided on one side of the disc 51, a second bidirectional threaded rod 54 is rotatably mounted on the inner surface of the chute 52, a fourth slider 53 is slidably mounted on the inner surface of the chute 52, both of the fourth sliders 53 are threadedly connected to the second bidirectional threaded rod 54, a seventh motor 532 is fixedly mounted on one side of one of the fourth sliders 53, the output end of the seventh motor 532 is fixedly connected to a friction roller 531, one end of the second bidirectional threaded rod 54 is fixedly connected to an eighth motor 55, and the eighth motor 55 is fixedly mounted on the outer surface of the disc 51; Three first balancing blocks 56 are evenly fixedly mounted on the outer surface of the disc 51 , and a second balancing block 57 is fixedly mounted on one side of the fourth slider 53 .

[0025] When the existing stainless steel pipe flattening machine flattens stainless steel pipes of different diameters, the accessories of the flattening machine need to be replaced, which has low work efficiency and delays time. Therefore, a stainless steel pipe flattening machine that can be easily adjusted to flatten stainless steel pipes of different diameters is needed.

[0026] When the present invention is in use, the stainless steel pipe is first placed on the top of the base plate 1, and then the position to be cut is moved to the same vertical plane as the cutting machine 37. At this time, the cutting of the stainless steel pipe can be achieved by rotating the cutting machine 37 around the gear ring 3. After the cutting is completed, the end of the stainless steel pipe is close to the disc 51, and the friction roller 531 can be extended into the inner cavity of the stainless steel pipe. The second bidirectional threaded rod 54 is rotated by the output shaft of the eighth motor 55. The second bidirectional threaded rod 54 cooperates with the slide 52 to limit the fourth slider 53, which can drive the fourth slider 53 to slide in the inner cavity of the slide 52. The fourth slider 53 brings the friction roller 531 close to the inner wall of the stainless steel pipe and contacts the inner wall of the stainless steel pipe. The friction roller 531 is rotated by the output shaft of the seventh motor 532 to remove burrs at the cut part of the stainless steel pipe. The disc 51 is rotated by the output shaft of the sixth motor 501. The disc 51 further performs a circular motion with the friction roller 531 through the fourth slider 53, so that the friction roller 531 can rub and eliminate the burrs on the stainless steel pipe. The three first balancing blocks 56 and the eighth motor 55 have the same mass, and the center of gravity of the three first balancing blocks 56 and the eighth motor 55 is evenly distributed on the outer surface of the disc 51. The second balancing block 57 and the friction roller 531 and the seventh motor 532 have the same shape and mass, so the disc 51 can remain stable during rotation.

[0027] Further, such as Figure 2 and Figure 3 As shown, four third grooves 13 are provided on the top of the base plate 1, and a second slider 2 is slidably installed on the inner surface of the third groove 13. A rotating shaft 21 is rotatably installed on the inner surface of the second slider 2. The two rotating shafts 21 on the same side are fixedly connected by a connecting rod 201, and the two ends of the rotating shaft 21 are respectively fixedly connected to a driving roller 23 and a first pulley 22.

[0028] When the present invention is in use, the second slider 2 can slide on the inner surface of the third groove 13, and the rotating shaft 21 can rotate on the inner surface of the second slider 2. When the rotating shaft 21 rotates, the two ends of the rotating shaft 21 will respectively rotate with the driving roller 23 and the first pulley 22.

[0029] Further, such as Figure 4As shown, a fourth groove 14 is formed at the bottom of the base plate 1, and a first slider 15 is slidably mounted on the inner surface of the fourth groove 14. A slide plate 24 is fixedly connected to the bottom of the first slider 15, and a first spring rod 244 is fixedly connected to one side of the slide plate 24. The first spring rod 244 is fixedly mounted on the bottom of the base plate 1; Two first gears 241 are rotatably mounted on one side of the slide 24, and the two first gears 241 are meshed with each other. A second pulley 242 is fixedly mounted on one side of the first gear 241, and a first motor 243 is fixedly connected to one side of one of the second pulleys 242. The first motor 243 is fixedly mounted on one side of the slide 24; The adjacent second pulley 242 and first pulley 22 are driven by a belt 25 . One side of the first pulley 22 is rotatably connected to a rotating block 252 . One side of the rotating block 252 is fixedly connected to a second spring rod 253 . The second spring rod 253 is fixedly mounted on the bottom of the base plate 1 .

[0030] When the present invention is in use, the output shaft 343 drives the second pulley 242 to rotate, and the second pulley 242 drives the first gear 241 to rotate. The two first gears 241 both start to rotate and drive the other second pulley 242 to rotate in the opposite direction. At this time, the two first pulleys 22 driven by the two belts 25 both start to rotate in opposite directions, and the driving roller 23 driven by the rotating shaft 21 also starts to rotate. At this time, the stainless steel pipe is between the two driving rollers 23. The rotation of the two driving rollers 23 can drive the stainless steel pipe to move on the top of the bottom plate 1. When in use, the two first gears 241 both start to rotate and drive the other second pulley 242 to rotate in the opposite direction. The two spring rods 253 respectively support the two rotating blocks 252 and the first pulley 22, so that the two driving rollers 23 are also in close contact with the stainless steel pipe. The slide plate 24 is lifted by the first spring rod 244, so that the belt 25 can be kept taut and transmission can be achieved. The first slider 15 slides on the inner surface of the fourth groove 14 to limit the slide plate 24 to prevent the slide plate 24 from tilting when sliding. The stainless steel pipe is located between the four driving rollers 23. The four driving rollers 23 can both limit the stainless steel pipe and drive the stainless steel pipe to slide on the top of the base plate 1.

[0031] Further, such as Figure 5 As shown, a first groove 11 is formed on the top of the base plate 1, and the gear ring 3 is fixedly mounted on the inner surface of the first groove 11. A fifth groove 31 is formed on one side of the gear ring 3, and two rotating rods 32 are rotatably mounted on the inner surface of the fifth groove 31. One end of the two rotating rods 32 is rotatably connected to a mounting plate 33. A second motor 34 is fixedly connected to one side of the mounting plate 33. The output shaft of the second motor 34 is fixedly connected to a second gear 35. The second gear 35 is meshed with the gear ring 3. A first electric telescopic rod 36 is fixedly mounted on one side of the mounting plate 33 , and an output end of the first electric telescopic rod 36 is fixedly connected to a cutting machine 37 .

[0032] When the present invention is in use, in order to enable the cutter 37 to rotate in a circle to cut the stainless steel pipe, the second motor 34 output shaft drives the second gear 35 to rotate, and the second gear 35 is engaged with the gear ring 3 and can slide on the inner surface of the fifth groove 31 through the mounting plate 33 with the two rotating rods 32, thereby achieving the purpose of making the mounting plate 33 perform a circular motion around the gear ring 3. At the same time, the mounting plate 33 also drives the cutter 37 to perform a circular motion to achieve the cutting of the stainless steel pipe. When facing stainless steel pipes of different diameters, the output end of the first electric telescopic rod 36 is extended and shortened to move with the cutter 37, thereby achieving the purpose of cutting stainless steel pipes of different diameters.

[0033] Further, such as Figure 6 As shown, a second groove 12 is opened on one side of the base plate 1, and a mounting ring 4 is slidably installed on the inner surface of the second groove 12, and a third slider 43 is slidably installed on the inner surface of the mounting ring 4. A second electric telescopic rod 44 is fixedly connected to one side of the third slider 43, and the second electric telescopic rod 44 is fixedly installed on one side of the mounting ring 4. A threaded rod 41 is rotatably installed on the inner surface of the second groove 12, and the threaded rod 41 is threadedly connected to the mounting ring 4. One end of the threaded rod 41 is fixedly connected to a third motor 42, and the third motor 42 is fixedly installed on one side of the third motor 42; A fourth motor 45 is fixedly installed at the bottom of the third slider 43, and the output shaft of the fourth motor 45 is fixedly connected to the third electric telescopic rod 46. The output end of the third electric telescopic rod 46 is fixedly connected to the mounting block 47. Two splints 471 are slidably installed in the inner cavity of the mounting block 47, and a sliding rod 472 is fixedly installed in the inner cavity of the mounting block 47. Both of the two splints 471 are slidably connected to the sliding rod 472. A first bidirectional threaded rod 473 is rotatably installed in the inner cavity of the mounting block 47. The first bidirectional threaded rod 473 is threadedly connected to the two splints 471. One end of the first bidirectional threaded rod 473 is fixedly connected to the fifth motor 474, and the fifth motor 474 is fixedly installed on one side of the mounting block 47.

[0034] When the present invention is in use, before cutting the stainless steel pipe, the output end of the second electric telescopic rod 44 moves the third slider 43, and the third slider 43 further moves the mounting block 47, and the mounting block 47 moves together with the two clamping plates 471 so that the two clamping plates 471 are respectively located on both sides of the stainless steel pipe. Then, the output shaft of the fifth motor 474 rotates the first bidirectional threaded rod 473, and the first bidirectional threaded rod 473 drives the two clamping plates 471 to move closer to each other, thereby clamping the stainless steel pipe. This can increase the stability of the stainless steel pipe when cutting; After the cutting is completed, the mounting block 47 is moved upward by the output end of the third electric telescopic rod 46. At this time, the stainless steel pipe will also move upward, and then the third electric telescopic rod 46 and the mounting block 47 are rotated by the output shaft of the fourth motor 45, and the stainless steel pipe will also rotate, and the other end of the stainless steel pipe is rotated to face the disc 51, and then the stainless steel pipe is flattened by the friction roller 531. Then, the third slider 43 is pushed to slide by the output end of the second electric telescopic rod 44 to push the stainless steel pipe to the top side of the base plate 1 to realize the unloading of the stainless steel pipe. The threaded rod 41 is rotated by the output shaft of the third motor 42, and the threaded rod 41 drives the mounting ring 4 to slide on the inner surface of the second groove 12. The mounting ring 4 moves with the cut stainless steel pipe and can be adjusted according to the position of stainless steel pipes of different lengths. The output shaft of the fourth motor 45 drives the mounting block 47 to rotate to the flat angle and then self-lock.

[0035] Working principle: When the present invention is in use, first place the stainless steel tube on the top of the bottom plate 1. At this time, the stainless steel tube squeezes the four driving rollers 23 apart in pairs. At this time, the two second spring rods 253 respectively support the two rotating blocks 252, and then the output shaft of the first motor 243 drives the second pulley 242 to rotate. The second pulley 242 drives the first gear 241 to rotate. The two first gears 241 are meshed with each other, and then the other first gear 241 drives the other second pulley 242 to rotate. The two first pulleys 22 are driven by the two belts 25 to rotate. The two first pulleys 22 respectively drive the two driving rollers 23 to rotate through the two rotating shafts 21. The two driving rollers 2 The synchronous rotation can drive the stainless steel pipe to move on the top of the base plate 1. When the stainless steel pipe cutting position moves to the same vertical plane as the cutter 37, the second gear 35 is rotated by the output shaft of the second motor 34. The second gear 35 engages with the gear ring 3, and the mounting plate 33 is moved by the second motor 34. The mounting plate 33 rotates with the two rotating rods 32 on the inner surface of the fifth groove 31, thereby achieving the purpose of moving the cutter 37 through the mounting plate 33. When encountering stainless steel pipes of different diameters, the cutter 37 can be moved by the output end of the first electric telescopic rod 36 to adjust the moving radius of the cutter 37, thereby achieving cutting of stainless steel pipes of different diameters.

[0036] When cutting the stainless steel pipe, it is necessary to fix the other end of the stainless steel pipe. When installing the stainless steel pipe, first place the stainless steel pipe between the two clamping plates 471, and rotate the first bidirectional threaded rod 473 through the output shaft of the fifth motor 474. The first bidirectional threaded rod 473 drives the two clamping plates 471 to approach each other and clamp the stainless steel pipe. This can make the stainless steel pipe more stable during cutting. After the cutting is completed, the mounting block 47 is lifted by the output end of the third electric telescopic rod 46 to lift the cut stainless steel pipe, and then the third electric telescopic rod 46 is rotated by the output shaft of the fourth motor 45 to rotate the stainless steel pipe 180 degrees, so that the stainless steel pipe is cut. One end corresponds to the disc 51, and then the threaded rod 41 is rotated by the output shaft of the third motor 42. The threaded rod 41 cooperates with the second groove 12 to limit the mounting ring 4, so that the threaded rod 41 drives the mounting ring 4 to slide, so that the friction roller 531 can contact the inner wall of the stainless steel pipe, and the friction roller 531 is rotated by the output shaft of the seventh motor 532, so that the friction roller 531 can flatten the stainless steel pipe. The second bidirectional threaded rod 54 is rotated by the output shaft of the eighth motor 55, so that the fourth slider 53 can move with the seventh motor 532 and the friction roller 531, thereby changing the working radius of the friction roller 531, thereby achieving the purpose of cutting stainless steel pipes of different diameters.
