Description

Technical Field

[0001] This utility model relates to the field of strip cooling technology, specifically a strip immersion length adjustment device based on immersion cooling method. Background Technology

[0002] Special high-copper alloys (such as titanium bronze and nickel bronze), high-nickel-based high-temperature alloys, precision alloys, functional materials, and high-content aluminum alloy strips have long faced a technical bottleneck in implementing reversible rolling processes when entering the cold roughing stage after hot rolling to a thickness of 3–15 mm. Currently, these materials are still generally rolled using a unidirectional, single-pass method during cold rolling: after the strip is uncoiled from the left uncoiler, it can only be rolled once in a single direction, then unloaded from the coiler, and then transported back to the uncoiler for the next pass. This process is repeated multiple times to roll the strip to the target thickness of 0.1–1.0 mm. If a reversible rolling process is attempted, the deformation heat and frictional heat generated during the subsequent rolling pass will be superimposed with the residual heat from the previous pass, easily causing the local temperature of the strip to rise above the metal phase transformation point or recrystallization temperature. This causes the expected cold rolling process to essentially become a warm rolling process, severely affecting the mechanical properties and surface quality of the strip.

[0003] To overcome the aforementioned temperature rise problem, our R&D personnel designed a cooling box structure. This structure uses guide rollers arranged at the lower end and upper ends of both sides of the box to allow the strip to run along a V-shaped path within the rolling oil-filled cooling box, achieving immersion cooling. However, in practical use, this structure easily leads to "over-cooling" of the strip, increasing the load on the rolling oil circulation cooling system and resulting in wasted energy and cooling medium, leading to low overall energy efficiency.

[0004] Therefore, this application provides a strip immersion length adjustment device based on immersion cooling method to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a strip immersion length adjustment device based on immersion cooling. Through the coordinated adjustment of the lead screw, slider and electric push rod, the path length and immersion depth of the strip in the rolling oil can be flexibly changed, thereby accurately controlling the cooling time and adapting to the cooling requirements of different materials and process stages. At the same time, it can avoid unnecessary cooling load, reduce the pressure of the rolling oil circulation cooling system, and significantly reduce energy consumption and operating costs, which can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a strip immersion length adjustment device based on immersion cooling method, comprising two parallel sliding rods, each end of which is provided with a mounting plate, a slider is slidably mounted on the sliding rod, the bottom of the slider is provided with a lifting and lowering fixed frame, and an upper guide roller and a lower guide roller are rotatably mounted on the side of the fixed frame.

[0007] As a preferred technical solution of this utility model, the middle part of the slider is threaded with a lead screw, the lead screw is rotatably connected to the mounting plate, and a geared motor for driving the lead screw to rotate is provided on one side of the mounting plate. The lead screw is connected to the output shaft of the geared motor through a coupling.

[0008] As a preferred technical solution of this utility model, the mounting plate is provided with a sliding sleeve that is slidably mounted on the sliding rod.

[0009] As a preferred embodiment of this utility model, the bottom of the slider is provided with an electric push rod, and the telescopic end of the electric push rod is connected to the fixed frame.

[0010] As a preferred embodiment of this utility model, the upper surface of the fixing frame is provided with a telescopic rod that connects to the bottom of the slider.

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a strip immersion length adjustment device based on immersion cooling method, including two parallel sliding rods 1, each end of which is provided with a mounting plate 2, a slider 3 slidably mounted on the sliding rod 1, and a lifting and lowering fixed frame 6 at the bottom of the slider 3. An upper guide roller 7 and a lower guide roller 8 are rotatably mounted on the side of the fixed frame 6 and are arranged in parallel. The cooling time of the strip in the rolling oil is controlled by adjusting the position of the guide rollers, thereby ensuring that the cooled strip can be rolled in reverse.

[0016] Furthermore, a lead screw 4 is threadedly connected to the middle of the slider 3. The lead screw 4 is rotatably connected to the mounting plate 2, and a reduction motor 41 that drives the lead screw 4 to rotate is provided on one side of the mounting plate 2. The lead screw 4 is connected to the output shaft of the reduction motor 41 through a coupling. The reduction motor 41 drives the lead screw 4 to rotate, thereby causing the slider 3 to move along the slide rod 1. The slider 3 drives the fixed frame 6 to move through the telescopic rod 61, thereby adjusting the horizontal position of the upper guide roller 7 and the lower guide roller 8.

[0017] Furthermore, the mounting plate 2 is provided with a sliding sleeve 31 that is slidably mounted on the slide rod 1 to reduce friction.

[0018] Furthermore, the bottom of the slider 3 is provided with an electric push rod 5. The telescopic end of the electric push rod 5 is connected to the fixed frame 6. The electric push rod 5 drives the fixed frame 6 to move up and down. The fixed frame 6 drives the upper guide roller 7 and the lower guide roller 8 to move up and down, thereby adjusting the height of the upper guide roller 7 and the lower guide roller 8.

[0019] Furthermore, the upper surface of the fixing frame 6 is provided with a telescopic rod 61 that is connected to the bottom of the slider 3, which serves as a guide.

[0020] The geared motor 41 and electric push rod 5 used in this utility model are common electronic components in the prior art. Their working methods and circuit structures are known technologies and will not be described in detail here.

[0021] When using: like Figure 3 As shown, when it is necessary to control the time when the strip is immersed in the rolling oil to be shortened, the geared motor 41 is controlled to work. The geared motor 41 drives the lead screw 4 to rotate, thereby causing the slider 3 to move to the left along the slide bar 1. The slider 3 drives the fixed frame 6 to move to the left through the telescopic rod 61. At the same time, the electric push rod 5 is shortened, and the electric push rod 5 drives the fixed frame 6 to move upward. At this time, the lower guide roller 8 guides the strip and shortens the cooling time of the strip in the rolling oil. Conversely, such as Figure 4 As shown, when it is necessary to control the increase of the strip immersion time in rolling oil, the geared motor 41 is controlled to rotate in the reverse direction. The geared motor 41 drives the lead screw 4 to rotate in the reverse direction, thereby causing the slider 3 to move to the right along the slide bar 1. The slider 3 drives the fixed frame 6 to move to the right through the telescopic rod 61. At the same time, the electric push rod 5 is extended, which drives the fixed frame 6 to move down and immerses the upper guide roller 7 in the cooling rolling oil. At this time, the upper guide roller 7 guides the strip, thereby increasing the cooling time of the strip in the rolling oil.

[0022] This invention, through the coordinated adjustment of the lead screw 4, slider 3, and electric push rod 5, can flexibly change the path length and immersion depth of the strip in the rolling oil, thereby precisely controlling the cooling time and adapting to the cooling requirements of different materials and process stages. At the same time, it can avoid unnecessary cooling load, reduce the pressure on the rolling oil circulation cooling system, and significantly reduce energy consumption and operating costs.
