Abstract
Description
Technical Field
[0001] This utility model relates to an openable and closable straightening gate structure, belonging to the field of steel pipe straightening technology. Background Technology
[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. It uses straightening rollers to compress the bar or other material, changing its straightness. Generally, there are two rows of straightening rollers, though the number varies. Some straightening machines have multiple rollers, while others have only two. These rely on the angle changes of two sets of rollers (with a concave center, hyperbolic rollers) to straighten materials of different diameters. A steel pipe straightening machine, specifically, uses straightening rollers to compress the steel pipe, changing its straightness. Currently, steel pipes are fed into the straightening machine in a straight line via conveyor rollers. If the steel pipe is placed directly on the rotating conveyor rollers while they are running, the material will be thrown out. Furthermore, when the steel pipe is first fed into the straightening machine, some conveyor rollers still support it. When the straightening machine's rollers apply a reverse force to the steel pipe, it will twist and roll, making it prone to being thrown out during transport and causing accidents. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an openable and closable straightening gate structure that is convenient to operate, limits the steel pipe during straightening to prevent the steel pipe from being thrown out, and does not affect the discharge of steel pipe after straightening.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: an openable and closable straightening gate structure, including multiple sets of straightening gate units, which are evenly spaced along the length of the steel pipe; each of the straightening gate units includes a frame, an open fixed cylinder is provided on the frame, a cover plate is provided on the top of the fixed cylinder, and a gate is hinged on the cover plate. The gate is driven to rotate around the hinge point, so that the gate moves close to the opening of the fixed cylinder and closes the fixed cylinder, or the gate moves away from the opening of the fixed cylinder and opens the fixed cylinder.
[0005] A horizontally arranged rotating shaft is provided above the cover plate, and the rotating shaft is fixed to the cover plate by a bearing seat; the material gate is fixed on the rotating shaft.
[0006] A connecting plate is provided on the outer side of the material gate, and a hydraulic cylinder seat is provided on the cover plate. A hydraulic cylinder is hinged on the hydraulic cylinder seat, and the extension rod of the hydraulic cylinder is fixedly connected to the connecting plate.
[0007] The material gate is an L-shaped structural component.
[0008] Liners are provided on the inner side of the material gate and the inner side of the fixed material cylinder, respectively.
[0009] Compared with the prior art, the advantages of this utility model are: an openable and closable straightening gate structure, which is convenient to operate; the gate cooperates with the fixed cylinder to limit the steel pipe during straightening and prevent the steel pipe from being thrown out; after straightening, it does not affect the discharge of the steel pipe.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0015] like Figure 1 , 2 As shown in Figure 3, an openable straightening gate structure in this embodiment includes multiple straightening gate units. These units are evenly spaced along the length of the steel pipe. During straightening, the straightening gate units close to limit the steel pipe and prevent it from being thrown out. After straightening, the straightening gate units open to facilitate the removal of the steel pipe from the straightening station. Each straightening gate unit includes a frame 6, on which an open-type fixed cylinder 3 is mounted. A horizontally arranged cover plate 2 is mounted on top of the fixed cylinder 3. A horizontally arranged rotating shaft 5 is mounted above the cover plate 2, and the rotating shaft 5 is fixed to the cover plate 2 via a bearing seat 1, allowing it to rotate within the bearing seat 1. A hydraulic cylinder seat 9 is mounted on top of the cover plate 2, and the cylinder body of a hydraulic cylinder 4 is hinged to the hydraulic cylinder seat 9. An L-shaped gate 7 is mounted on the rotating shaft 5, and a connecting plate 8 is mounted on the outer side of the gate 7. The extension rod of the hydraulic cylinder 4 is fixedly connected to the connecting plate 8. When the hydraulic cylinder 4 extends its rod, it pushes the connecting plate 8, causing the rotating shaft 5 to rotate, which in turn drives the material gate 7 to approach the fixed material cylinder 3, thereby closing the opening of the fixed material cylinder and limiting the steel pipe to prevent it from moving. When the hydraulic cylinder 4 retracts its rod, it pushes the connecting plate 8, causing the rotating shaft 5 to rotate, which in turn drives the material gate 7 to approach the fixed material cylinder 3, thereby opening the opening of the fixed material cylinder 3.
[0016] Liners 10 are installed on the inner side of the material gate and the inner side of the fixed material cylinder to reduce wear on the steel pipe surface.
[0017] This application is easy to operate. The material gate and the fixed material cylinder cooperate to limit the steel pipe during the straightening process and prevent the steel pipe from being thrown out. After the straightening is completed, it does not affect the discharge of the steel pipe.
[0018] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
