Abstract
Description
Technical Field
[0001] This invention relates to the field of edge rolling machine technology, and more specifically, to an I-beam edge rolling machine. Background Technology
[0002] The edge rolling and shaping of I-beams is a systematic hot rolling process carried out by an edge rolling mill. Through multiple plastic processes, the billet is processed into a profile with an I-shaped cross-section. After the billet is heated, it is conveyed to the edge rolling mill, where multiple rollers extrude the billet. The billet passes through multiple edge rolling mills in sequence and is shaped in sequence, so that the billet gradually forms the prototype of an I-beam. During the rolling process of the billet on multiple edge rolling mills, it is also necessary to guide and descaling.
[0003] In the existing technology, the billet is fed into the edging mill at a relatively high speed, and the distance between the edging mills is relatively short. After completing one rolling, the billet quickly enters the next rolling process. Therefore, a guide device is installed on the side of the edging mill to guide the movement direction of the billet and prevent the billet from failing to enter the next edging mill accurately, thus preventing billet blockage. The existing guide device has a fixed size. When the clearance left for the billet to move is large, the billet may impact the guide device and cause it to bounce, thus failing to align with the next edging mill. When the clearance of the billet to move is small, the billet may impact the guide device and cause it to lift up, or it may cause billet blockage. Summary of the Invention
[0004] To overcome the above-mentioned defects, embodiments of the present invention provide an I-beam edge rolling mill, which solves the technical problem that the guide device on the edge rolling mill in the prior art is difficult to dynamically adjust the guiding effect of the billet.
[0005] A steel edging mill for I-beams includes a billet, a rolling section, and a guide frame. The billet passes through the rolling section and the guide frame. The guide frame is disposed on the side of the rolling section. A guide device is provided on the guide frame. The guide device further includes an upper limiting member, a lower limiting member, a drive cylinder, and a dynamic limiting mechanism. The upper and lower limiting members are both fixedly connected to the guide frame and are respectively disposed on the upper and lower sides of the billet. Both the upper and lower limiting members are connected to an external water pump, enabling spraying of the billet. After leaving the rolling section, the billet enters between the upper limiting member and the lower limiting member. The ends of the upper and lower limiting members near the rolling section are set to be open. Two dynamic limiting mechanisms are respectively set on both sides of the billet and slidably connected to the guide frame. A drive cylinder is fixedly installed on the side of the guide frame near the rolling section. The drive cylinder can drive the dynamic limiting mechanism to move on the side near the rolling section, thereby adjusting the width of the billet when it enters between the two dynamic limiting mechanisms.
[0006] A limiting frame is provided on the guide frame, and the limiting frame is located at one end of the guide frame away from the rolling section. The dynamic limiting mechanism includes an extension plate, a guide plate, and a retracting plate. The extension plate is slidably connected to the limiting frame, the guide plate is rotatably connected to the extension plate, and the retracting plate is rotatably connected to the guide plate. The retracting plate is located on the side close to the rolling section, and a pusher is connected to the retracting plate. The output end of the drive cylinder is fixedly connected to the pusher, and the pusher is slidably connected to the guide frame.
[0007] The gathering plate is provided with an arc segment one and an arc segment two. The center of the arc segment one is oriented away from the blank, and the center of the arc segment two is oriented towards the blank. One end of the gathering plate provided with the arc segment one is rotatably connected to the guide plate.
[0008] The extension of the output end of the drive cylinder can push the pusher frame to slide on the guide frame. The pusher frame can drive the folding plate to slide, and the folding plate remains parallel to the sliding during the sliding process. When the folding plate slides, it can drive the guide plate to move. When the guide plate moves, the extension plate slides in the limiting frame, and the angle between the guide plate and the extension plate changes accordingly when the guide plate moves.
[0009] Multiple rollers are rotatably connected to the guide plate. When the guide plate rotates with the gathering plate to a position close to the billet, the rollers can contact the billet. The rollers are driven by the movement of the billet to rotate, cleaning the side of the billet.
[0010] Both the upper limiting member and the lower limiting member are disposed between the two dynamic limiting mechanisms. The shapes of the upper limiting member and the lower limiting member are compatible with the guide plate and the gathering plate. The ends of the upper limiting member and the lower limiting member near the rolling section are bent toward the side away from the billet.
[0011] A first drain outlet is provided on the side of the upper limiting member near the billet. The first drain outlet is inclined and the inclination direction of the first drain outlet is towards the rolling section. Water distribution outlets facing the sides of the billet are provided on both sides of the first drain outlet. A second drain outlet is provided on the side of the lower limiting member facing the billet. There is a certain gap between the upper limiting member and the lower limiting member and the dynamic limiting mechanism on both sides, and the water sprayed on the billet flows out through the gap.
[0012] The beneficial effects of this invention are as follows: In this invention, upper and lower limiting members are set to simultaneously limit the vertical movement of the billet. When the end of the billet warps, it can be guided. A dynamic limiting mechanism is set so that the guide device can dynamically adjust the range of movement of the billet. When the billet leaves the rolling mill and enters the guide device, the guiding range can be expanded to reduce the possibility of the end of the billet warping or bending during the guiding process. At the same time, after the billet enters the next rolling mill, the guiding range can be narrowed so that the water used for dephosphorization can have more sufficient contact with the billet.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] like Figures 1-6 As shown, an I-beam edge rolling mill according to an embodiment of the present invention is illustrated, comprising a billet 1, a rolling section 2, and a guide frame 3. The billet 1 passes through the rolling section 2 and the guide frame 3. The guide frame 3 is disposed on the side of the rolling section 2. A guide device is disposed on the guide frame 3, and the guide device further includes an upper limiting member 4, a lower limiting member 5, a drive cylinder 6, and a dynamic limiting mechanism. The upper limiting member 4 and the lower limiting member 5 are both fixedly connected to the guide frame 3 and are respectively disposed on the upper part of the billet 1. On both sides, the upper limiting member 4 and the lower limiting member 5 are connected to an external water pump, enabling spraying of the billet 1. After leaving the rolling section 2, the billet 1 enters between the upper limiting member 4 and the lower limiting member 5. The ends of the upper limiting member 4 and the lower limiting member 5 near the rolling section 2 are set to be open. Two dynamic limiting mechanisms are respectively set on both sides of the billet 1 and are slidably connected to the guide frame 3. A drive cylinder 6 is fixedly installed on the side of the guide frame 3 near the rolling section 2. This device can drive the dynamic limiting mechanism to move closer to the rolling section 2, thereby adjusting the width of the billet 1 when it enters between the two dynamic limiting mechanisms. Traditional guide devices are fixed through slot devices with a funnel shape. After the billet 1 is rolled by the rolling section 2, it enters the through slot and is guided along the through slot to the rolling section 2 of the next edge rolling mill for the next rolling. In this application, the through slot is composed of the upper limiting member 4, the lower limiting member 5 and the two dynamic limiting mechanisms. The two dynamic limiting mechanisms can dynamically adjust the angle of the part in contact with the billet 1. When the end of the billet 1 enters between the dynamic limiting mechanisms, the contact range can be enlarged. After guiding the billet 1 to the next edge rolling mill, the range of the guide can be reduced to limit the movement of the billet 1. Compared with traditional guide devices, this can reduce the impact and lifting that may be caused by the fast-moving billet 1 and the guide device, which could lead to bending and blockage of the high-temperature and soft billet 1.
[0023] like Figures 1-6As shown, a limiting frame 7 is provided on the guide frame 3. The limiting frame 7 is located at the end of the guide frame 3 away from the rolling section 2. The dynamic limiting mechanism includes an extension plate 8, a guide plate 9, and a gathering plate 10. The extension plate 8 is slidably connected in the limiting frame 7. The guide plate 9 is rotatably connected to the extension plate 8. The gathering plate 10 is rotatably connected to the guide plate 9. The gathering plate 10 is located on the side close to the rolling section 2. A pusher frame 11 is connected to the gathering plate 10. The output end of the drive cylinder 6 is fixedly connected to the pusher frame 11. The pusher frame 11 is slidably connected to the guide frame 3. The output end of the drive cylinder 6 drives the gathering plate 10 to move parallel through the pusher frame 11. When the gathering plate 10 moves, it drives the guide plate 9 to move as well. At this time, the opening of the guide device facing the rolling section 2 becomes larger. When one end of the billet 1 is tilted, it can enter the guide device better, avoiding the situation where the tilted end is offset too far and the billet 1 is blocked.
[0024] like Figures 3-6 As shown, the gathering plate 10 is provided with an arc segment 12 and an arc segment 13. The center of the arc segment 12 is oriented away from the billet 1, and the center of the arc segment 13 is oriented towards the billet 1. One end of the gathering plate 10 with the arc segment 12 is rotatably connected to the guide plate 9. The purpose of providing the arc segment 12 and the arc segment 13 is to allow the billet 1 to bounce or bend towards the guide plate 9 when it comes into contact with the gathering plate 10 after moving away from the rolling section 2. Compared with the traditional guide device which is set with a trumpet-shaped end, the billet 1 may bounce when it hits the guide device, causing the billet 1 to be unable to move to the next rolling mill. The arc setting of the gathering plate 10 in this application can reduce the difficulty of guiding the billet 1 after it bounces.
[0025] like Figures 3-6 As shown, the output end of the drive cylinder 6 extends to push the pusher frame 11 to slide on the guide frame 3. The pusher frame 11 can drive the gathering plate 10 to slide, and the gathering plate 10 remains parallel during the sliding process. When the gathering plate 10 slides, it can drive the guide plate 9 to move. When the guide plate 9 moves, the extension plate 8 slides in the limiting frame 7, and the angle between the guide plate 9 and the extension plate 8 changes accordingly. As the gathering plates 10 in the two dynamic limiting mechanisms gradually move away from each other, the guide plate 9 also gradually tilts to form a fan shape. The extension plate 8 slides in the limiting frame 7, but the distance between them remains unchanged, so that the two dynamic limiting mechanisms form a convergence shape. By adjusting the convergence range when the billet 1 enters the two guide devices, the accuracy of guiding the end of the billet 1 is improved. After successful guidance, the two gathering plates 10 move closer to each other, so that the guide plate 9 guides the billet 1.
[0026] like Figures 4-6As shown, multiple rollers 14 are rotatably connected to the guide plate 9. When the guide plate 9 rotates with the gathering plate 10 to a position close to the billet 1, the rollers 14 can contact the billet 1. The rollers 14 are driven by the movement of the billet 1 to rotate, cleaning the side of the billet 1. The top and bottom of the billet 1 can be dephosphorized by spraying through the drain outlet 15 and the drain outlet 16, respectively. Due to the air hammer reaction, the high temperature of the billet 1 surface can cause the oxide layer to fall off when it comes into contact with water. However, the side of the billet 1 does not come into sufficient contact with water. During the rotation of the rollers 14, the side of the billet 1 is also squeezed, causing the oxide layer scales to fall off and separate.
[0027] like Figures 3-6 As shown, the upper limiting member 4 and the lower limiting member 5 are both disposed between the two dynamic limiting mechanisms. The shapes of the upper limiting member 4 and the lower limiting member 5 are matched with the guide plate 9 and the gathering plate 10. The ends of the upper limiting member 4 and the lower limiting member 5 near the rolling section 2 are bent away from the side of the billet 1, so that they will not come into contact with the upper limiting member 4 and the lower limiting member 5 when the gathering plate 10 moves.
[0028] like Figures 5-6 As shown, a drain outlet 15 is provided on the side of the upper limiting member 4 near the billet 1. The drain outlet 15 is inclined and the inclined direction of the drain outlet 15 is towards the rolling section 2. Water distribution outlets facing the sides of the billet 1 are provided on both sides of the drain outlet 15. A drain outlet 26 is provided on the side of the lower limiting member 5 facing the billet 1. There is a certain gap between the upper limiting member 4 and the lower limiting member 5 and the dynamic limiting mechanism. The water sprayed on the billet 1 flows out through the gap. The inclined shape of the drain outlet 15 can avoid the end of the billet 1 from colliding with the drain outlet 15 when it moves. The water distribution outlets on both sides of the drain outlet 15 guide some water to the side of the billet 1, so that the surface of the billet 1 can be evenly contacted with water. The drain outlet 26 sprays water upwards and directly contacts the billet 1. More drain outlets 26 can be provided to avoid insufficient contact between the bottom of the billet 1 and the water.
[0029] This embodiment provides an I-beam edge rolling mill. By setting a guide plate 9 and a gathering plate 10, when the end of the billet 1 enters the guide device, the output end of the drive cylinder 6 shortens and pulls the gathering plate 10 to move horizontally, thereby increasing the guiding range of the billet 1. This avoids the billet 1 colliding with the frame when entering the guide device, which could cause the billet 1 to warp or bend, making it difficult to accurately enter the next rolling section 2. After the billet 1 enters the next rolling mill for rolling, the output end of the drive cylinder 6 can extend... The long pusher plate 10 moves, causing the guide plate 9 to move as well, reducing the range of movement of the billet 1. At the same time, the roller 14 can contact the side of the billet 1 to clean the oxide layer scales on the side of the billet 1. Meanwhile, during the movement of the billet 1, the drain outlet 15 and the drain outlet 16 spray water onto the surface of the billet 1. Due to the air hammer effect, the scales are cleaned. The billet 1 is wrapped by the dynamic limiting mechanism, the upper limiting member 4 and the lower limiting member 5, which also allows the water to better contact the surface of the billet 1.
[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
