[0015] Beneficial effects

[0016] 1. In this invention, a cleaning plate is used to clean rust or debris from seamless steel pipes. When the straightening machine's guiding device straightens the seamless steel pipes, the bent seamless steel pipes are inserted into the inner side of the cleaning plate via a guide plate. The conical structure of the guide plate guides the direction of the seamless steel pipes, allowing the wire brushes on the inner side of the cleaning plate to clean the rust or debris from the outer side of the seamless steel pipes. This prevents rust or debris from being ejected and injuring nearby operators during the straightening process, and ensures the cleanliness of the outer side of the seamless steel pipes, facilitating their use after straightening and reducing the workload of repeated cleaning.

[0017] 2. In this invention, one end of the bent seamless steel pipe is positioned by using a pallet and a fixing plate. When the material guiding device straightens the seamless steel pipe, the fixing plate is installed on the pallet with fixing bolts to fix one end of the seamless steel pipe, so that the seamless steel pipe moves horizontally in a vertical direction. This prevents one end of the seamless steel pipe from moving randomly when it is under pressure, and reduces the workload of operators in supporting the steel pipe to move it, thereby improving the workload of straightening the seamless steel pipe.

[0033] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0034] Example: Please refer to Figures 1 to 8 As shown:

[0035] This invention provides a material guiding device for straightening seamless steel pipes, comprising: a main body 1, two motors installed on the inner side of the main body 1, a threaded rod installed at the output end of one motor, the side end of the threaded rod being installed on the inner side of the main body 1 via a bearing seat, a guide groove provided at the bottom of the inner side of the main body 1, a bracket installed at the bottom of the main body 1, and a cleaning component 2 installed at the side end of the main body 1; the cleaning component 2 includes a sliding groove 201, which is rectangular in structure and located on the inner side of the main body 1; and a positioning component 3 installed on the outer side of the main body 1, which includes an outer plate 301, with a groove on the outer side of the outer plate 301, and the outer plate 301 being rotatably mounted on both sides of the main body 1.

[0036] The main body 1 includes: a vertical groove 101 located inside the main body 1; a guide groove 102 located inside the main body 1, with its side connected to the side of one of the vertical grooves 101; and a sliding rod 103 with protrusions on its outer ends, which are slidably mounted inside the vertical groove 101. Multiple sliding rods 103 are connected at one end by a chain assembly, and the other ends of two sliding rods 103 are also connected. The system includes: a bevel gear; an upper guide wheel 104 with an arc-shaped structure in the middle and a protrusion on its outer side, mounted on the outer side of the slide rod 103 at the upper position; a lower guide wheel 105 with a groove on its outer side, in which the protrusion on the outer side of the upper guide wheel 104 is installed, mounted on the outer side of the slide rod 103; a rotating component 106 rotatably mounted on the other end of the slide rod 103; a connecting plate 107, the side end of which is connected to the outer side of the rotating component 106 via a rotating shaft; a traction plate 108, the outer side of which is connected to the other side of the connecting plate 107 via a rotating shaft, mounted on a threaded rod at the motor output end inside the main body 1; and a sliding plate 109, which is slidably mounted inside the guide groove 102, with a bevel gear rotatably mounted on its outer end. The bevel gear at the outer end of the plate 109 meshes with the bevel gear at the other end of the slide rod 103; the positioning plate 1010 is installed on the side of the slide plate 109, and the side end of the positioning plate 1010 is rotatably installed on the outer side of the other end of the two slide rods 103; the vertical rod 1011 has a protrusion on its outer side, and the vertical rod 1011 is installed on the output end of another motor on the inner side of the main body 1, and the vertical rod 1011 is slidably installed in the middle position of the bevel gear at the outer end of the slide plate 109;Storage box 1012 is installed at the bottom of the main body 1. When the guiding device straightens the seamless steel pipe, the bent seamless steel pipe is inserted between the upper guide wheel 104 and the lower guide wheel 105. A motor inside the main body 1 drives the vertical rod 1011 to rotate, causing the vertical rod 1011 to slide on the bevel gear at the outer end of the slide plate 109. The bevel gear rotates at the outer end of the slide plate 109, causing the bevel gear at the outer end of the slide plate 109 to drive the bevel gear at one end of the two sliding rods 103 to rotate, thus causing the slide plate to rotate. The rotation directions of rods 103 are opposite. The other ends of multiple sliding rods 103 are connected by a chain assembly, causing the sliding rods 103 to drive the upper guide wheel 104 and the lower guide wheel 105 to rotate. This causes the upper guide wheel 104 and the lower guide wheel 105 to move the seamless steel pipe inside the main body 1 for straightening. For seamless steel pipes with a large degree of curvature, another motor-driven threaded rod inside the main body 1 drives the traction plate 108 to move. This causes the outer side of the traction plate 108 to drive the connecting plate 10 through a rotating shaft. 7. The connecting plate 107 moves, causing the rotating component 106 to move. The rotating component 106 then drives the sliding rod 103 to move along the vertical groove 101, increasing the distance between the upper guide wheel 104 and the lower guide wheel 105. Simultaneously, the outer side of one end of each sliding rod 103 moves the positioning plate 1010, causing the positioning plate 1010 to move the sliding plate 109 along the guide groove 102. This also drives the sliding rod 103 to rotate, causing the upper guide wheel 104 and the lower guide wheel 105 to straighten the seamless steel pipe with a large bend, reducing the pressure of the motor drive. For seamless steel pipes with a small bend, another motor-driven threaded rod inside the main body 1 rotates in the opposite direction, causing the rotating component 106 to move in the opposite direction, reducing the distance between the upper guide wheel 104 and the lower guide wheel 105, and straightening the seamless steel pipe. The protrusion on the outer side of the upper guide wheel 104 is inserted into the groove on the outer side of the lower guide wheel 105 to prevent slippage and deviation when pressure is applied to the steel pipe, ensuring the levelness of the straightening.

[0037] The cleaning component 2 further includes: a cleaning plate 202, which is cylindrical in shape and has a guide groove at its bottom. A wire brush is located on the inner side of the cleaning plate 202, and carrier plates are installed on both sides of the cleaning plate 202. The top and bottom of the carrier plates are slidably mounted inside the slide groove 201 via springs. A guide plate 203, which is conical in shape and installed on the side of the cleaning plate 202, is used when the material guiding device straightens the seamless steel pipe. One end of the seamless steel pipe is inserted into the cleaning plate 202 through the inner side of the guide plate 203. Inside the guide plate 203, the tapered structure guides the direction of the steel pipe, causing one end of the seamless steel pipe to move towards the inside of the cleaning plate 202. As the seamless steel pipe bends, the carrier plate on the outside of the cleaning plate 202 moves along the slide groove 201 under the action of the spring, allowing the wire brush on the inside of the cleaning plate 202 to clean the rust or debris on the outside of the seamless steel pipe. This prevents the large pressure during straightening from ejecting debris or other personnel and injuring them. The debris cleaned by the cleaning plate 202 falls into the storage box 1012 for storage, facilitating later cleaning.

[0038] The positioning component 3 further includes: a side plate 302, which is slidably installed in a groove on the outer side of the outer plate 301; a side groove 303, which is L-shaped and located on the side of the side plate 302; a slider 304, which is L-shaped and slidably installed inside the side groove 303; an extension plate 305, which is installed on the outer end of the slider 304; a support plate 306, which has an arc-shaped structure in the middle and its two ends are rotatably installed between the two side ends of the extension plate 305; and a fixing plate 307, which is fixed on the support plate 306 by fixing bolts. When the material guiding device straightens the seamless steel pipe, the two ends of the extension plate 305 are connected to the support plate 306. The side plate 306 rotates between the side ends of the long plate 305, so that the seamless steel pipe is placed in the arc-shaped structure in the middle of the support plate 306. The fixing plate 307 is installed on the support plate 306 by using fixing bolts to fix one end of the seamless steel pipe, so that the steel pipe and the side plate 302 are kept parallel. As the seamless steel pipe moves between the upper guide wheel 104 and the lower guide wheel 105, the extension plate 305 drives the slider 304 to move along the side groove 303, so that the side plate 302 moves in the groove outside the outer plate 301, and drives the outer plate 301 to rotate on both sides of the main body 1, so that the seamless steel pipe moves from a bent state to a horizontal state, guiding the straightening direction of the steel pipe and reducing the workload of the operator in supporting the movement of the steel pipe.

[0039] In another embodiment, the installation of the positioning component 3 is eliminated on the outside of the main body 1, further reducing the overall volume of the main body 1 and reducing production costs.

[0040] The specific usage and function of this embodiment: In this invention, when the material guiding device straightens the seamless steel pipe, one end of the seamless steel pipe is first inserted into the inner side of the cleaning plate 202 through the inner side of the guide plate 203. Then, the other end of the seamless steel pipe is placed in the arc-shaped structure in the middle of the support plate 306. The other end of the seamless steel pipe is fixed by using the fixing plate 307. The seamless steel pipe moves between the upper guide wheel 104 and the lower guide wheel 105. The extension plate 305 drives the slider 304 to move along the side groove 303. The side plate 302 moves in the groove outside the outer plate 301 and drives the outer plate 301 to move in the main body 1. The two sides rotate to guide the straightening direction of the steel pipe. As the seamless steel pipe bends, the carrier plate on the outer side of the cleaning plate 202 moves along the slide 201, so that the wire brush on the inner side of the cleaning plate 202 cleans the rust or debris on the outer side of the seamless steel pipe. A motor on the inner side of the main body 1 drives the vertical rod 1011 to rotate. The vertical rod 1011 drives the bevel gear at the outer end of the slide plate 109 to rotate, which drives the bevel gear at one end of the two slide rods 103 to rotate. The other ends of the multiple slide rods 103 are connected by a chain group, so that the slide rods 103 drive the upper guide wheel 104 and the lower guide wheel 105 to rotate, thereby moving the seamless steel pipe to straighten it.

[0041] For seamless steel pipes with a large degree of curvature, another motor-driven threaded rod inside the main body 1 drives the traction plate 108 to move the rotating component 106 through the connecting plate 107. The rotating component 106 drives the slide rod 103 to move along the vertical groove 101, increasing the distance between the upper guide wheel 104 and the lower guide wheel 105. This allows the upper guide wheel 104 and the lower guide wheel 105 to straighten the seamless steel pipe with a large degree of curvature, reducing the pressure of the motor drive. As the degree of curvature of the steel pipe decreases, the distance between the upper guide wheel 104 and the lower guide wheel 105 decreases, thus straightening the seamless steel pipe.

[0042] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.

[0043] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
