Description

Technical Field

[0001] This utility model belongs to the field of steel strip rolling technology, and in particular relates to a double steel strip rolling equipment. Background Technology

[0002] The double steel strip calender is an industrial production equipment mainly used to extrude, cool, and shape molten materials through two parallel steel strips to produce sheet or plate products with specific thickness and width. Through the continuous transmission of the steel strips, the material is extruded in the gap formed between the pressure rollers and the steel strips to form a finished product of the required thickness, and the material can be rapidly cooled by the cooling system inside the steel strips.

[0003] During the use of double steel strip calendering equipment, the thickness of the items to be calendered varies, resulting in different opening angles at the calender feed point and causing the steel strip to tilt. Since the hydraulic push rod remains in its original position, the force on the inner side of the steel strip changes, which may cause damage to the steel strip during use. To solve the above problems, there is an urgent need for a double steel strip calendering equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when rolling materials of different thicknesses, the steel strip itself will tilt due to the different opening angles at the feed point, but the hydraulic push rod is still in the original position, which can easily damage the steel strip. Therefore, a double steel strip rolling equipment is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double steel strip rolling equipment, comprising a steel strip module, a frame on both sides of the steel strip module, a guide groove on one side of the frame, and an adjustment seat on the inner side of the steel strip module; an installation component, which is slidably installed inside the frame; and a hydraulic component, which is installed inside the installation component and located inside the steel strip of the steel strip module. The mounting assembly includes a mounting frame, on which a support plate is slidably mounted via a groove on its inner side. Connecting frames are mounted on both sides of the mounting frame, and sliding frames are slidably mounted on the connecting frames via grooves on their inner sides. A pressing block is mounted on the top of the sliding frame, and a connecting rod is rotatably mounted on the bottom of the sliding frame. The other end of the connecting rod is rotatably connected to the support plate, and a connecting column is rotatably mounted on the connecting rod via a through hole on its inner side.

[0006] As a further description of the above technical solution: The connecting column is fixedly connected to the inner wall of the mounting frame, and the connecting bracket is slidably connected to the guide groove.

[0007] As a further description of the above technical solution: A telescopic rod is fixedly installed on the bottom side of the extrusion block, and a pressure block is fixedly installed at the bottom end of the telescopic rod.

[0008] As a further description of the above technical solution: The telescopic rod is equipped with a spring on its outer wall, and the connection points between the support plate and the sliding frame and the connecting rod are all grooves.

[0009] As a further description of the above technical solution: The hydraulic assembly includes a hydraulic push rod, a connecting block is fixedly installed at the top of the hydraulic push rod, a turntable is slidably installed on the outer wall of the connecting block, and a connecting seat is rotatably installed on the outer wall of the turntable.

[0010] As a further description of the above technical solution: The turntable is slidably mounted with a pin rod through a through hole in its interior, and the pin rod is slidably connected to the connecting block through a through hole in the connecting block.

[0011] As a further description of the above technical solution: The hydraulic push rod has a connecting sleeve at its telescopic end, and a pressure plate is installed at the bottom end of the connecting sleeve. The top surface of the connecting seat is fixedly connected to the support plate.

[0012] As a further description of the above technical solution: The connecting seat has an opening on one side corresponding to the connecting block, and the turntable has a through opening corresponding to the connecting block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, when rolling items of different thicknesses, the position of the hydraulic push rod's point of action can be changed by adjusting the position of the mounting frame. This ensures that when the angle of the steel strip changes with the angle of the feed inlet, the hydraulic push rod is evenly stressed on the steel strip surface by adjusting the position of the mounting frame and the hydraulic push rod. This reduces the possibility of uneven force distribution on the steel strip surface caused by the different opening angle of the feed inlet and the different tilt angle of the steel strip due to the different thickness of the items, which could lead to damage to the steel strip.

[0014] In this invention, when disassembling and repairing the hydraulic push rod, the pin rod can be pulled out and the connecting sleeve separated from the telescopic end of the hydraulic push rod. Then, by rotating the hydraulic push rod, the connecting block is aligned with the opening of the connecting seat, and the connecting block is slid out from the opening, thereby disassembling the hydraulic push rod. This allows for convenient and quick disassembly and repair of the hydraulic push rod, thereby improving the efficiency of disassembly and repair and reducing the impact on the operation of the calender.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In its specific implementation, such as Figures 1-5 This utility model provides a technical solution: a double steel strip rolling equipment, including a steel strip module 1, frames 2 on both sides of the steel strip module 1, a guide groove 6 on one side of the frame 2, and an adjustment seat 3 inside the steel strip module 1; an installation component 4, which is slidably installed inside the frame 2; and a hydraulic component 5, which is installed inside the installation component 4 and located inside the steel strip of the steel strip module 1. The steel strip module 1 is known in the technical field, so it is not described in detail here. The mounting component 4 includes a mounting frame 41, on which a support plate 43 is slidably mounted through a groove on the inner side. Connecting frames 42 are mounted on both sides of the mounting frame 41. Sliding frames 46 are slidably mounted on the connecting frames 42 through grooves on their inner sides. A pressing block 47 is mounted on the top of the sliding frame 46. A connecting rod 44 is rotatably mounted on the bottom of the sliding frame 46. The other end of the connecting rod 44 is rotatably connected to the support plate 43. A connecting column 45 is rotatably mounted on the connecting rod 44 through a through hole on its inner side. The connecting column 45 is fixedly connected to the inner wall of the mounting frame 41. The connecting frame 42 is slidably connected to the guide groove 6. A telescopic rod 48 is fixedly mounted on the bottom side of the pressing block 47. A pressure block 410 is fixedly mounted on the bottom of the telescopic rod 48. A spring 49 is provided on the outer wall of the telescopic rod 48. The connection points between the support plate 43, the sliding frame 46, and the connecting rod 44 are all sliding grooves.

[0023] Specifically, during the calendering process, when the angle of the feed point of the steel strip module 1 changes due to the change in the thickness of the material, the hydraulic push rod 55 can be contracted, thereby loosening the connection between the hydraulic component 5 and the steel strip module 1. Under the action of gravity, the hydraulic push rod 55 drives the support plate 43 to move downward, and then the sliding frame 46 moves upward under the action of the connecting rod 44 and the connecting column 45, thereby driving the extrusion block 47 to move upward and separating the extrusion block 47 from the guide groove 6. At the same time, under the action of the spring 49, the pressure block 410 and the guide groove 6 are kept in contact. Then, the mounting frame 41 is pushed to the appropriate position, and then the hydraulic push rod 55 is re-expanded to extrude the steel strip module 1. As the extrusion proceeds, the hydraulic push rod 55 can push the support plate 43 upward, thereby driving the sliding frame 46 downward and making the extrusion block 47 re-contact the guide groove 6. The extrusion of the extrusion block 47 further increases the connection between the mounting frame 41 and the frame 2, thereby ensuring the stability of the mounting frame 41 during use. like Figure 4 As shown, the hydraulic assembly 5 includes a hydraulic push rod 55, a connecting block 53 is fixedly installed at the top of the hydraulic push rod 55, a turntable 52 is slidably installed on the outer wall of the connecting block 53, a connecting seat 51 is rotatably installed on the outer wall of the turntable 52, a pin rod 54 is slidably installed on the turntable 52 through a through hole, the pin rod 54 is slidably connected to the connecting block 53 through a through hole, a connecting sleeve 56 is provided at the telescopic end of the hydraulic push rod 55, a pressure plate 57 is installed at the bottom end of the connecting sleeve 56, the top surface of the connecting seat 51 is fixedly connected to the support plate 43, an opening corresponding to the connecting block 53 is provided on one side of the connecting seat 51, and a through opening corresponding to the connecting block 53 is provided inside the turntable 52; Specifically, when disassembling and repairing the hydraulic push rod 55, the pin 54 can be pulled out, and the telescopic end of the hydraulic push rod 55 can be separated from the connecting sleeve 56. By rotating the hydraulic push rod 55, the turntable 52 can be rotated, so that the connecting block 53 corresponds to the opening on the outer wall of the connecting seat 51. This pushes the hydraulic push rod 55 outward, causing the connecting block 53 to separate from the turntable 52, thus removing the hydraulic push rod 55. When installing the hydraulic push rod 55, the connecting block 53 is aligned with the opening in the connecting seat 51 and the turntable 52, so that the connecting block 53 at the top of the hydraulic push rod 55 is pushed into the turntable 52. Then, by rotating the turntable 52, the connecting block 53 is made perpendicular to the opening in the connecting seat 51, and the pin 54 is reinserted into the turntable 52 and the connecting block 53 for fixation. Finally, the telescopic end of the hydraulic push rod 55 is connected to the connecting sleeve 56.

[0024] Working principle: During the calendering process, as the thickness of the material changes, the angle at the feed point of the steel strip module 1 changes. The hydraulic push rod 55 retracts, loosening the connection between the hydraulic assembly 5 and the steel strip module 1. Under gravity, the hydraulic push rod 55 moves the support plate 43 downwards. The connecting rod 44 and connecting column 45 then move the sliding frame 46 upwards, causing the extrusion block 47 to move upwards and separate from the guide groove 6. Simultaneously, the spring 49 ensures that the pressure block 410 remains in contact with the guide groove 6. The mounting frame 41 is then pushed to the appropriate position, and the hydraulic push rod 55 is retracted to extrude the steel strip module 1. As extrusion continues, the hydraulic push rod 55 pushes the support plate 43 upwards, causing the sliding frame 46 to move downwards and causing the extrusion block 47 to move downwards. When disassembling and repairing the hydraulic push rod 55, the pin rod 54 can be pulled out, and the telescopic end of the hydraulic push rod 55 can be separated from the connecting sleeve 56. By rotating the hydraulic push rod 55, the turntable 52 can be rotated, so that the connecting block 53 corresponds to the opening on the outer wall of the connecting seat 51. Pushing the hydraulic push rod 55 outward will cause the connecting block 53 to separate from the turntable 52, and the hydraulic push rod 55 can be removed. When installing the hydraulic push rod 55, align the connecting block 53 with the opening in the connecting seat 51 and the turntable 52, push the connecting block 53 at the top of the hydraulic push rod 55 into the turntable 52, and then rotate the turntable 52 so that the connecting block 53 is perpendicular to the opening in the connecting seat 51. Then, re-insert the pin rod 54 into the turntable 52 and the connecting block 53 for fixation. Finally, connect the telescopic end of the hydraulic push rod 55 to the connecting sleeve 56.
