Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strip production technology, and in particular to a steel strip fixing device for a cold rolling mill. Background Technology
[0002] A cold rolling mill is a key piece of equipment for rolling steel strips into steel pipes. It uses rotating rolls to apply pressure to the steel billet to achieve plastic deformation, producing pipes of different thicknesses and widths made from cold-rolled steel strips. It mainly consists of a frame, roll group, transmission system, hydraulic device, etc. The middle part of the equipment has a conveyor belt responsible for transporting the steel strip, which, together with guide rollers and other components, ensures stable transmission. During the production of steel pipes in the cold rolling mill, the steel strip needs to be transported through the conveyor belt in the middle of the machine, and then extrusion molding and welding processes are used to produce steel pipes. However, in the existing equipment, the movement of the steel strip on both sides of the conveyor belt is not smooth enough, and the sides of the conveyor belt lack precise guiding and positioning structures, which makes the steel strip prone to lateral deviation during high-speed transmission. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies, namely, the insufficient stability of the steel strip movement on both sides of the conveyor belt during the production of steel pipes in a cold rolling mill, and to provide a steel strip fixing device for a cold rolling mill.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cold rolling mill strip fixing device, comprising a baffle, a conveying body disposed on one side of the baffle, an adjusting plate disposed on one side of the baffle, a control plate fixedly connected to one side of the adjusting plate, a support plate movably connected to the outer surface of the control plate, a movable opening provided on the outer surface of the support plate, a connecting hoop fixedly connected to the bottom of the support plate, a connecting rod movably connected to the inner wall of the connecting hoop, a clamping groove provided on one side of the connecting rod, a clamping column engaged with the inner wall of the clamping groove, a connecting plate fixedly connected to the top of the clamping column, a movable column fixedly connected to the outer surface of the connecting plate, a support rod slidably connected to the top of the movable column via a circular groove, and a spring disposed on the outer surface of the support rod.
[0005] In a preferred embodiment, the bottom of the support plate is provided with a rack, the bottom of the rack is meshed with a gear, the two sides of the gear are rotatably connected to a support shaft, a top rod is provided on one side of the connecting plate, and a rotating shaft is fixedly connected to the top of the top rod.
[0006] In a preferred embodiment, the support shaft is fixedly connected to the outer surface of the baffle, and the top of the top rod is rotatably connected to the outer surface of the connecting plate via a rotating shaft.
[0007] In a preferred embodiment, the control panel is movable inside the movable port.
[0008] In a preferred embodiment, the outer surface of the connecting hoop is movably connected to the clamping post through a through hole.
[0009] In a preferred embodiment, the outer surface of the connecting hoop is provided with a movable groove, and the support rod is fixedly connected to the inside of the movable groove.
[0010] In a preferred embodiment, the two ends of the spring are fixedly connected to the inner wall of the moving groove and the top of the moving column, respectively.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, by incorporating an adjusting plate, ensures smoother lateral movement of the steel plate during its transport in the middle conveying section of the cold rolling mill, preventing lateral shifting. The adjusting plate's position is controlled by a control plate extending from one side, which moves within a movable opening in the support plate. The support plate facilitates the adjustment of the control plate, and connecting hoops and rods provide a structure on one side to prevent movement of the adjusted plate after adjustment. Furthermore, this design prevents excessive downward contact and friction between the top of the adjusting plate and the surface of the conveying body due to gravity when the plate moves a considerable distance towards the center. A clamping groove allows the clamping column to fit tightly against the inside of the connecting rod, and the top of the clamping column has an anti-slip layer to prevent the adjusting plate from easily shifting.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0020] like Figures 1-6 As shown, this utility model provides a technical solution: a cold rolling mill strip fixing device, including a baffle 1, a conveying body 2 disposed on one side of the baffle 1, an adjusting plate 3 disposed on one side of the baffle 1, a control plate 4 fixedly connected to one side of the adjusting plate 3, the control plate 4 being movable inside a moving opening 6, a support plate 5 being movably connected to the outer surface of the control plate 4, the moving opening 6 being opened on the outer surface of the support plate 5, a connecting hoop 7 being fixedly connected to the bottom of the support plate 5, a moving groove being opened on the outer surface of the connecting hoop 7, and a support rod 16 being fixedly connected inside the moving groove. The outer surface of the hoop 7 is movably connected to the clamping post 13 through a through hole. The inner wall of the hoop 7 is movably connected to the connecting rod 8. A clamping groove 12 is provided on one side of the connecting rod 8. The inner wall of the clamping groove 12 is engaged with the clamping post 13. The top of the clamping post 13 is fixedly connected to the connecting plate 14. The outer surface of the connecting plate 14 is fixedly connected to the moving post 15. The top of the moving post 15 is slidably connected to the support rod 16 through a circular groove. The outer surface of the support rod 16 is provided with a spring 17. The two ends of the spring 17 are fixedly connected to the inner wall of the moving groove and the top of the moving post 15, respectively.
[0021] In this embodiment, by setting an adjusting plate 3, the steel plate moves more smoothly on both sides when conveyed in the middle conveying section of the cold rolling mill, preventing lateral movement. The position of the adjusting plate 3 is controlled by a control plate 4 extending from one side, which moves within the moving opening 6 in the support plate 5. The support plate 5 is provided to facilitate the adjustment of the control plate 4. By setting a connecting hoop 7 and a connecting rod 8, a structure can be set on one side of both to prevent the adjusting plate 3 from moving after adjustment. In addition, it can prevent the adjusting plate 3 from moving too far towards the center of the conveying body. The top end will not rub against the surface of the conveying body 2 due to excessive contact with the downward force of gravity; the clamping groove 12 allows the clamping column 13 to fit tightly inside the connecting rod 8, and the top end of the clamping column 13 has an anti-slip layer to prevent the adjusting plate 3 from easily shifting; specifically, the clamping column 13 is connected to the moving column 15 through the connecting plate 14, and then the spring 17 rebounds to make the clamping column 13 pass through the through hole on one side of the connecting hoop 7 and stick to the clamping groove 12, while the moving column 15 moves in the moving groove and on the outer surface of the support rod 16 through the circular groove. Example 2
[0022] like Figure 3 and Figure 6 As shown, a rack 9 is provided at the bottom of the support plate 5, and a gear 10 is meshed at the bottom of the rack 9. Support shafts 11 are rotatably connected to both sides of the gear 10. A push rod 18 is provided on one side of the connecting plate 14, and a rotating shaft 19 is fixedly connected to the top of the push rod 18. The support shaft 11 is fixedly connected to the outer surface of the baffle 1, and the top of the push rod 18 is rotatably connected to the outer surface of the connecting plate 14 through the rotating shaft 19.
[0023] In this embodiment, by setting rack 9 and gear 10, the movement of control plate 4 during adjustment is made more stable. Rack 9 rotates on the outer surface of gear 10, and gear 10 rotates in place under the support of support shaft 11. By setting push rod 18 and rotating shaft 19, when it is necessary to adjust adjustment plate 3, clamping column 13 needs to be disengaged from clamping groove 12. After pulling clamping column 13 outward, push rod 18 can be flipped upward through rotating shaft 19 and pressed against the surface of connecting hoop 7 under the tension of spring 17. During the movement of adjustment plate 3 and control plate 4, it is not necessary to hold connecting plate 14 with your hand. In addition, push rod 18 is U-shaped and can be locked on both sides of clamping column 13 when flipped downward.
[0024] Working principle: like Figures 1-6As shown, when adjusting the control plate 4 and the adjustment plate 3 according to the width of the steel plate, the clamping column 13 needs to be disengaged from the clamping groove 12 first, and the spring 17 will be stretched. Then, the clamping column 13 is pulled outward by manually pulling the connecting plate 14. After that, the top rod 18 is flipped upward through the rotating shaft 19 and pressed against the surface of the connecting hoop 7. This will push the control plate 4 to drive the adjustment plate 3 for adjustment. At the same time, the surfaces of the rack 9 and the gear 10 move, and the gear 10 rotates in place at the support shaft 11. Finally, after the adjustment is completed, the top rod 18 is reversed, and the clamping column 13 is pushed through the through hole on one side of the connecting hoop 7 and pressed against the clamping groove 12 by the rebound force of the spring 17. Then, the moving column 15 moves in the moving groove and on the outer surface of the support rod 16 through the circular groove.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
