Description

Technical Field

[0001] The present application belongs to the field of cold rolling technology in the metallurgical industry, and in particular to a strip steel support assembly and a cold rolling production line. Background Art

[0002] The rolling of strip steel involves many equipments, such as rolling mill, roller table, flying shear equipment and coiler, etc. Between two adjacent equipments, a structure such as a guide plate is usually set to transfer the running strip steel from one equipment to another. The guide plate can also be called a support plate, a lining plate, etc., and the guide plate is fixedly connected to the frames of two adjacent equipments.

[0003] In the prior art, the specifications of the strip steel rolling production line are generally large, so the positions of various equipment and the guide plate in the strip steel rolling production line are generally fixed. When thin-gauge strip steel needs to be rolled, the thickness of the thin-gauge strip steel is basically about 0.2mm, and the strip head is softer than other steel types. When the thin-gauge strip steel is transferred from one device to another through the guide plate, due to the vibration, gravity and the soft material of the thin-gauge strip steel itself, the strip head of the thin-gauge strip steel is easy to fall, resulting in a large bend in the strip head. The strip head with a large bend is easy to get stuck in the lower part of the equipment that needs to be entered, causing steel piles. When steel piles occur, the operator needs to stop the strip threading operation and then use a crowbar or a broach to handle it. There is a great safety risk and each processing time is more than 10 minutes, which exceeds the normal allowable fault handling time of the cold rolling production line. The running strip steel will also continue to pile up under the action of inertia. Every time the strip head is stuck, it will cause the production line to stop and the accumulated strip steel will also produce a large amount of scrap steel, affecting the production efficiency of the cold rolling production line.

[0030] In order to enable technicians in the technical field to which the present application belongs to understand the present application more clearly, the technical solution of the present application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0031] Figure 1 The simplified structural diagram of the first device, the second device and the strip steel support assembly provided in this application is shown in FIG. Figure 1 The embodiment of the present application provides a strip steel support assembly, which is applied to a first device 10 and a second device 20 adjacent and spaced apart in a transition cold rolling production line. The strip steel support assembly is spaced apart from the running path of the strip steel. For ease of identification, Figure 1 The winning belt threading gap 30 is uniformly marked as 30, and the rack 40 of the first device 10 and the rack 40 of the second device 20 are uniformly marked as 40.

[0032] Figure 2 A top view of a steel support assembly provided for this application. Figure 2 The strip steel support assembly includes a mounting member 1, a guide member 2 and a driving mechanism 3.

[0033] The mounting member 1 is pivotally connected to the frame 40 of the first device 10 .

[0034] At least one guide member 2 is fixedly connected to the mounting member 1 and is located between the first device 10 and the second device 20. The guide member 2 is provided with a spaced connection portion 21 and a support portion 22, the connection portion 21 is connected to the mounting member 1, the support portion 22 extends to the frame 40 of the second device 20 and is supported on the frame 40 of the second device 20, and the support portion 22 faces the belt threading gap 30 of the second device 20.

[0035] The driving mechanism 3 is fixedly connected to the frame 40 of the first device 10 or the frame 40 of the second device 20. The driving mechanism 3 is provided with a reciprocating and retracting driving end 31, and the driving end 31 is used to reciprocate and retract to push the mounting member 1 to rotate relative to the connected frame 40, so that the support part 22 reciprocates and separates and moves up relative to the frame 40 of the second device 20 to contact with the falling, and the support part 22 separates and moves up to contact and support with the lower surface 100 of the strip.

[0036] For the first equipment 10 and the second equipment 20 in the cold rolling production line, there is a height difference in the strip gap 30. The strip support assembly can be spaced from the running path of the strip, so that the structure in the strip support assembly will not affect the normal operation of the strip. In the strip support assembly, the mounting member 1 is pivoted with the frame 40 of the first equipment 10, so the mounting member 1 can rotate around the frame 40 of the first equipment 10, and the rotation plane where the mounting member 1 is located is parallel to the length direction of the strip. The connecting portion 21 of at least one guide member 2 is fixedly connected to the mounting member 1, and the guide member 2 is located between the first equipment 10 and the second equipment 20. The position of the guide member 2 enables the guide member 2 to guide and support the strip passing through the two devices. The support portion 22 of the guide member 2, which is spaced from the connecting portion 21, extends and supports to the frame 40 of the second equipment 20, and faces the strip gap 30 of the second equipment 20. The strip can pass from the first equipment 10 with a larger height to the support portion 22 and then enter the strip gap 30 of the second equipment 20 from the support portion 22, playing a basic transition role. The driving mechanism 3 is connected and fixed to any frame 40 of the two devices, and the driving end 31 of the driving mechanism 3 reciprocates to push the mounting member 1 to rotate. The rotation of the mounting member 1 can drive the guide member 2 fixedly connected to the mounting member 1 to rotate, so that the support portion 22 of the guide member 2 supported on the frame 40 of the second device 20 is separated and moved upward relative to the frame 40 of the second device 20 to increase the height of the support portion 22. The support portion 22 with increased height can support the lower surface of the head of the strip passing through, and reduce the large bending of the head of the strip with softer material or thinner specification under the action of gravity when passing through the first device 10. The head with a small bending degree and within the normal range is not easy to interfere with the equipment to be entered and get stuck in the steel pile, thereby reducing the risk of stopping the production line due to the steel pile. When it is necessary to roll normal strip steel, the support portion 22 can be reset by falling. To a certain extent, the problem that the strip with softer material is easy to get stuck in the main steel pile and affect the production efficiency of the cold rolling production line is solved. Moreover, the above structure can also provide a good supporting effect for thicker or harder steel strips. The height of the upward movement of the support portion 22 of the guide portion can be adjusted. This application will not be elaborated here.

[0037] It should be noted that the length direction of the steel strip generally extends along the running direction of the steel strip, and the width direction A of the steel strip is generally perpendicular to the length direction of the steel strip. The spacing between the steel strip support assembly and the running path of the steel strip means that the steel strip support assembly as a whole will not interfere with the running path of the steel strip, which can avoid affecting the normal operation of the steel strip. The running path of the steel strip is the path that the steel strip passes from the beginning of normal rolling to the end of normal rolling of the steel strip. The support portion 22 shown in claim 1 extends to support the frame 40 of the second device 20, and the relevant description in the specification can be referred to.

[0038] For easier understanding, here is also provided Figure 3, Figure 3 Another simplified schematic diagram of the first device, the second device and the strip steel support assembly provided in this application, Figure 3 The support portion 22 of the middle guide member 2 moves upward relative to the frame 40 of the second device 20 to the lower surface 100 of the supporting strip. Figure 3 As shown in the figure, the head of the strip is allowed to have a certain degree of curvature, but the curvature cannot be too large. If it is too large, it will easily cause the steel pile to get stuck.

The driving mechanism 3 is connected to the frame 40 of the first device 10, and the distance between the driving mechanism 3 and the mounting member 1 is relatively close, which facilitates the driving end 31 of the driving mechanism 3 to push the mounting member 1. The driving mechanism 3 and the support portion 22 are spaced apart and distributed on both sides of the mounting member 1, which also facilitates the support portion 22 to adjust its position relative to the second device 20.

When the driving end 31 of the driving mechanism 3 reciprocates and extends, it can drive the mounting member 1 to rotate to adjust the position of the support portion 22 on the guide member 2.

[0041] In some embodiments provided in the present application, the mounting member 1 is lower than the belt-threading gap 30 of the first device 10, and higher than the belt-threading gap 30 of the second device 20. The mounting member 1 is higher than the belt-threading gap 30 of the second device 20, and the support portion 22 of the guide member 2 can be more easily extended to the frame 40 of the second device 20, which has a better supporting and guiding effect on the strip steel that is not easy to bend.

[0042] In certain embodiments provided in the present application, the mounting member 1 may also be equal to or lower than the belt threading gap 30 of the second device 20. The rotation of the mounting member 1 can drive the support portion 22 of the guide member 2 to adjust the height to achieve support for the strip steel.
