[0002] Steel pipes play a vital role in modern industrial production, not only used to manufacture mechanical parts but also as a structural steel material, used to manufacture building structures, pillars, and mechanical supports. After cutting, steel pipes often have varying degrees of burrs on the ends and inner bores, affecting product quality. Deburring and polishing the steel pipe surface are necessary to ensure pipe precision.

[0039] Reference Figures 1 to 8 The embodiment of the present invention provides a steel pipe automatic deburring and polishing composite machine, comprising:

[0040] The conveying mechanism 300 is used to convey the steel pipe horizontally, and during the conveying process, the axial direction of the steel pipe is horizontally perpendicular to the conveying direction of the conveying mechanism 300;

[0041] A plurality of grinding mechanisms are symmetrically arranged on both sides of the conveying mechanism 300 along the conveying direction of the conveying mechanism 300 . The grinding mechanisms are provided with grinding parts that can move in the vertical direction and in the direction parallel to the axial direction of the steel pipe.

[0042] The automatic steel pipe deburring and polishing machine according to the embodiments of the present invention has at least the following technical effects: the steel pipe to be polished is conveyed flat on a conveyor mechanism 300. The polishing mechanisms on both sides of the conveyor mechanism 300 polish the ends of the steel pipe, removing burrs from the steel pipe and polishing the outer surface of the steel pipe. It is understood that by selecting polishing parts of different materials, sizes, and hardness levels, deburring or polishing requirements can be met. When processing different batches of steel pipes, the lengths of the steel pipes may vary. By adjusting the horizontal distance between the polishing part and the ends of the steel pipes, the polishing part can contact the ends of steel pipes of different lengths, ensuring proper polishing. Furthermore, the polishing part may wear over time, and this adjustment allows it to be reused. When polishing the surface of the steel pipe, the vertical position of the polishing part and the distance between the polishing part and the outer surface of the steel pipe can be adjusted to ensure proper deburring. This embodiment has a simple structure, adopts machinery to replace manual labor, can perform batch grinding processing on steel pipes, liberates labor, improves production efficiency, and has good promotion prospects.

[0043] In some embodiments of the present invention, the grinding mechanism includes a deburring mechanism 100; the deburring mechanism 100 is provided with a first base 101, and the first base 101 is provided with a first mounting seat 103 and a second mounting seat 104 distributed side by side along the conveying direction of the conveying mechanism 300, and the first mounting seat 103 and the second mounting seat 104 can be mounted on the first base 101 so as to be movable and adjustable in the direction of approaching or moving away from the conveying mechanism 300; a first rotating shaft 105 that can be raised and lowered is provided between the first mounting seat 103 and the second mounting seat 104, and the axial direction of the first rotating shaft 105 is parallel to the conveying direction of the conveying mechanism 300, and the grinding part includes a first grinding wheel 106 provided on the first rotating shaft 105. Figure 1 and Figure 3 The first grinding wheel 106 is mounted on the first rotating shaft 105. As the steel pipe passes through the deburring mechanism 100, the first grinding wheel 106 deburrs the end of the steel pipe on the conveyor mechanism 300 during rotation. The first mounting seat 103 and the second mounting seat 104 slide on the first base 101 to adjust the distance between the first grinding wheel 106 and the steel pipe on the conveyor mechanism 300, making the deburring mechanism 100 suitable for deburring steel pipes of varying lengths.

[0044] In some embodiments of the present invention, a first mounting plate 102 capable of sliding along the conveying direction of the conveying mechanism 300 is provided on the first base 101, and a first mounting seat 103 and a second mounting seat 104 are arranged on the first mounting plate 102. By adjusting the position of the first mounting plate 102 relative to the first base 101, the synchronous sliding of the first mounting seat 103 and the second mounting seat 104 can be achieved.

[0045] In some embodiments of the present invention, a first screw 110 is vertically provided on the side of the first mounting seat 103 close to the conveying mechanism 300, and a second screw 112 is vertically provided on the side of the second mounting seat 104 close to the conveying mechanism 300; the two ends of the first rotating shaft 105 are correspondingly installed on the first screw 110 and the second screw 112 to achieve lifting and lowering through the rotation of the first screw 110 and the second screw 112.

[0046] In some embodiments of the present invention, Figure 1 The first screw rod 110 is provided with a first nut 111 and a first lifting seat 114. The first lifting seat 114 is connected to the first nut 111 and can move on the first screw rod 110 along with the first nut 111; the second screw rod 112 is provided with a second nut 113 and a second lifting seat 115. The second lifting seat 115 is connected to the second nut 113 and can move on the second screw rod 112 along with the second nut 113; the two ends of the first rotating shaft 105 are respectively arranged on the first lifting seat 114 and the second lifting seat 115.

[0047] In some embodiments of the present invention, a first hand wheel 116 is provided at the top of the first screw 110, and a second hand wheel 117 is provided at the top of the second screw 112. By simultaneously rotating the first hand wheel 116 and the second hand wheel 117, the first lifting seat 114 and the second lifting seat 115 can be moved synchronously, thereby realizing the vertical movement of the first grinding wheel 106.

[0048] In some embodiments of the present invention, the first grinding wheel 106 is connected to a first drive mechanism, which includes a first motor 107 mounted on the first base 101. The first motor 107 is connected to one end of the first rotating shaft 105 via a first timing belt 108. Belt drives have the advantages of simple structure, smooth transmission, vibration damping, low cost, no lubrication required, and easy maintenance.

[0049] In some embodiments of the present invention, a tensioning pulley 109 is provided on one side of the first synchronous belt 108. During installation, the first synchronous belt 108 must be tensioned. However, after working for a period of time, the first synchronous belt 108 is stretched and becomes loose, prone to slipping, and must be re-tensioned. The tensioning pulley 109 uses a spring or oil pressure to generate a force to tighten the belt, so that the first synchronous belt 108 can be pressed on the pulley of the first synchronous belt 108 with appropriate pressure.

[0050] In some embodiments of the present invention, the grinding mechanism includes a polishing mechanism 400; the polishing mechanism 400 is provided with a second base 401, and the second base 401 is provided with a third mounting seat 403 and a fourth mounting seat 404 distributed side by side along the conveying direction of the conveying mechanism 300, and the third mounting seat 403 and the fourth mounting seat 404 can be mounted on the second base 401 so as to be movable and adjustable in the direction of approaching or moving away from the conveying mechanism 300; a second rotating shaft 405 and a third rotating shaft 406 spaced apart and parallel in the vertical direction are provided between the third mounting seat 403 and the fourth mounting seat 404, and the third mounting seat 403 and the fourth mounting seat 404 can approach or move away from each other in the vertical direction, and the axial directions of the second rotating shaft 405 and the third rotating shaft 406 are parallel to the conveying direction of the conveying mechanism 300, and the grinding part includes a second grinding wheel 407 provided on the second rotating shaft 405 and a third grinding wheel 408 provided on the third rotating shaft 406. Figure 3 and Figure 4The steel pipe is transported on the conveyor mechanism 300. When the steel pipe passes the location of the polishing mechanism 400, the second grinding wheel 407 and the third grinding wheel 408 rotate to polish the outer surfaces of both ends of the steel pipe on the conveyor mechanism 300. The sliding movement of the third mounting seat 403 and the fourth mounting seat 404 on the first base 101 can adjust the distance between the polishing mechanism 400 and the steel pipe on the conveyor mechanism 300, making the polishing mechanism 400 suitable for polishing steel pipes of different lengths. In addition, the distance between the second grinding wheel 407 and the third grinding wheel 408 can be adjusted by adjusting the distance between the second rotating shaft 405 and the third rotating shaft 406, allowing the polishing mechanism 400 to polish steel pipes of different diameters.

[0051] In some embodiments of the present invention, a second mounting plate 402 capable of sliding along the conveying direction of the conveying mechanism 300 is provided on the second base 401, and a third mounting seat 403 and a fourth mounting seat 404 are arranged on the second mounting plate 402. By adjusting the position of the second mounting plate 402 relative to the second base 401, the synchronous sliding of the third mounting seat 403 and the fourth mounting seat 404 can be achieved.

[0052] In some embodiments of the present invention, a third screw 409 is vertically provided on the side of the third mounting seat 403 close to the conveying mechanism 300, and the third screw 409 includes a first upper rod segment and a first lower rod segment with opposite thread rotation directions. A fourth screw 412 is vertically provided on the side of the fourth mounting seat 404 close to the conveying mechanism 300, and the fourth screw 412 is provided with a second upper rod segment and a second lower rod segment corresponding to the thread of the third screw 409. The two ends of the second rotating shaft 405 are correspondingly installed on the first upper rod segment and the second upper rod segment, and the two ends of the third rotating shaft 406 are correspondingly installed on the first lower rod segment and the second lower rod segment, so that the second grinding wheel 407 and the third grinding wheel 408 can be moved closer to or farther away from each other through the rotation of the first screw 110 and the second screw 112.

[0053] In some embodiments of the present invention, Figure 4The first upper rod section is provided with a third nut 410 and a third lifting seat 415, the third lifting seat 415 is connected to the third nut 410 and can move along with the third nut 410 on the third screw 409; the first lower rod section is provided with a fourth nut 411 and a fourth lifting seat 416, the fourth lifting seat 416 is connected to the fourth nut 411 and can move along with the fourth nut 411 on the fourth screw 412; the first lower rod section is provided with a fifth nut 413 and a fifth lifting seat 417, the fifth lifting seat 417 is connected to the fifth nut 413 and can move along with the fifth nut 413 on the fifth screw 502; the first lower rod section is provided with a sixth nut 414 and a sixth lifting seat 418, the sixth lifting seat 418 is connected to the sixth nut 414 and can move along with the sixth nut 414 on the sixth screw. Since the threads of the first upper rod segment and the third upper rod segment have the same rotation direction, the threads of the first lower rod segment and the second lower rod segment have the same rotation direction, and the threads of the first upper rod segment and the second upper rod segment have opposite rotation directions, when the third screw 409 and the fourth screw 412 rotate, the third lifting seat 415 and the fifth lifting seat 417 will move up / down in the vertical direction. At the same time, the fourth lifting seat 416 and the sixth lifting seat 418 will move up / down in the vertical direction, thereby achieving the second rotating shaft 405 and the third rotating shaft 406 to move closer to or away from each other.

[0054] In some embodiments of the present invention, a third hand wheel 419 is provided at the top of the third screw 409, and a fourth hand wheel 420 is provided at the top of the fourth screw 412. By rotating the third hand wheel 419 and the fourth hand wheel 420, the second rotating shaft 405 and the third rotating shaft 406 can be moved closer to or farther away from each other.

[0055] In some embodiments of the present invention, the polishing mechanism 400 is driven by a second driving mechanism, which includes a second motor 421 , and the second rotating shaft 405 , the third rotating shaft 406 and the second motor 421 are connected via a second synchronous belt.

[0056] In some embodiments of the present invention, the polishing mechanism 400 is provided with a limiting mechanism 500, which includes a first limiting plate 501 spanning the third mounting seat 403 and the fourth mounting seat 404. The first limiting plate 501 is provided with a fifth screw 502, the axial direction of the fifth screw 502 is parallel to the axial direction of the steel pipe, and the end of the fifth screw 502 close to the transmission mechanism 300 is provided with a second limiting plate 503. The second limiting plate 503 can enter and exit the area between the second grinding wheel 407 and the third grinding wheel 408 as the fifth screw 502 rotates. Figure 5 and Figure 6The limiting mechanism 500 plays a limiting role. It is understandable that the steel pipe can easily be dragged along by the second grinding wheel 407 and the third grinding wheel 408 during polishing. The second limiting plate 503 of the limiting mechanism 500 can abut the two ends of the steel pipe to prevent the steel pipe from moving to the two ends. In addition, the polishing length of the steel pipe can be changed by the limiting mechanism 500. Specifically, by adjusting the fifth screw 502, the second limiting plate 503 can be extended between the second grinding wheel 407 and the third grinding wheel 408. The second limiting plate 503 can push the steel pipe so that the steel pipe moves along the axial direction of the steel pipe, thereby increasing the length of the other end of the steel pipe extending into the polishing mechanism 400 on the other side, thereby lengthening the polishing length.

[0057] In some embodiments of the present invention, the limiting mechanism 500 further includes a first guide rod 504 and a second guide rod 505, respectively disposed on either side of the fifth screw rod 502. One end of the first guide rod 504 and the second guide rod 505 are connected to the first limiting plate 501, and the other end is connected to the second limiting plate 503. The provision of the first guide rod 504 and the second guide rod 505 makes the limiting adjustment more stable.

[0058] In some embodiments of the present invention, Figure 3 There are two deburring mechanisms 100, which are symmetrically arranged on both sides of the conveying direction of the conveying mechanism 300; there are two polishing mechanisms 400, which are symmetrically arranged on both sides of the conveying direction of the conveying mechanism 300; the polishing mechanism 400 is located behind the deburring mechanism 100 relative to the conveying direction of the conveying mechanism 300.

[0059] In some embodiments of the present invention, the distance between the two polishing mechanisms 400 can be adjusted. Figure 3 The automatic deburring and polishing machine for steel pipes is provided with a frame 700, a conveying mechanism 300 is provided on the frame 700, a second base 401 of one polishing mechanism 400 is fixedly provided on the frame 700, and the second base 401 of the other polishing mechanism 400 is provided on the frame 700 by sliding, and can move closer to or away from the conveying mechanism 300 in the horizontal direction during the sliding process. It is understandable that in order to adapt to the size of the polishing mechanism 400, the size design space of the limiting mechanism 500 is limited. When the polishing length needs to be significantly adjusted, the adjustment function of the limiting mechanism 500 may not meet the requirements. Therefore, in this embodiment, the spacing between the polishing mechanisms 400 on both sides can be adjusted on the frame 700, which can better meet the requirements of different polishing lengths.

[0060] In some embodiments of the present invention, the steel pipe automatic deburring and polishing composite machine is provided with a feeding mechanism 200, combined with Figure 3The feeding mechanism 200 is provided with a feeding rack that is tilted downward toward the conveying mechanism 300 , which can allow the steel pipe to automatically slide down into the conveying mechanism 300 .

[0061] In some embodiments of the present invention, the conveying mechanism 300 includes at least two parallel and spaced transmission screws 301, and the discharge ends of the transmission screws 301 are each provided with a downwardly inclined discharge plate 303. Figure 3 and Figure 7 The transmission screw 301 is fixed by setting up multiple screw fixing frames 302, and the polished steel pipe can be slid down along the discharge plate 303 and discharged.

[0062] In some embodiments of the present invention, a composite automatic deburring and polishing machine for steel pipes includes a press mechanism 600, which includes a press rod 601 positioned above a drive screw 301. The spacing between the press rod 601 and the drive screw 301 is adjustable. During polishing, the steel pipe needs to be pressed down to prevent it from moving upward while ensuring that it can rotate flexibly. Specifically, a preset spacing of 5 to 10 mm is provided between the press rod 601 and the steel pipe, and the spacing between the press rod 601 and the drive screw 301 can be adjusted according to the radial size of the steel pipe.

[0063] In some embodiments of the present invention, a sheet metal shield 701 is provided on the outside of the deburring mechanism 100 and the polishing mechanism 400, and a first opening 702 is provided on the side of the sheet metal shield 701 close to the conveying mechanism 300. Figure 8 The first opening 702 is provided to make room for steel pipe processing, and the sheet metal shield 701 can prevent the operator from accidentally touching the grinding part and getting injured, while protecting the grinding part from being damaged by other objects.

[0064] In some embodiments of the present invention, a second opening and a cover 703 capable of opening and closing the second opening are provided on the top of the sheet metal shield 701. The second opening facilitates the operator to adjust the position of the polishing mechanism 400 and the deburring mechanism 100, and also facilitates maintenance and replacement of parts.
