Description

Technical Field

[0001] This utility model relates to the technical field of the cold-rolled steel industry, specifically a floating synchronous degreasing device. Background Technology

[0002] A large amount of heat is generated during strip rolling, and rolling oil is needed to cool the strip and rolls. However, when the strip is coiled after rolling, the rolling oil on the surface of the strip needs to be removed as much as possible. The degreasing device can achieve this function.

[0003] Degreasing devices typically use a pair of degreasing rollers to press the upper and lower surfaces of the strip for degreasing. Because the strip rolling line fluctuates vertically, traditional structures use a fixed lower roller and a powered upper roller that presses downwards. This results in inconsistent pressure exerted by the upper and lower degreasing rollers on the upper and lower surfaces of the strip, failing to achieve complete degreasing. Another structural design uses powered upper and lower degreasing rollers, both of which can be adjusted towards the strip rolling line. However, this requires position feedback for both roller movements, is more complex to operate, and has a higher equipment cost. Poor degreasing performance directly affects the equipment's operating speed and, in severe cases, can cause the coiled strip to slip and prevent normal rolling.

[0004] Therefore, we propose a floating synchronous oil removal device. Utility Model Content

[0005] The problem to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a floating synchronous oil removal device to solve the problems mentioned in the background art.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A floating synchronous oil removal device includes a lower roller support, a base, an upper roller support, and a side limiting mechanism. A lower oil removal roller is rotatably connected between the inner walls of the two sides of the lower roller support. The lower surface of the lower roller support is connected to the base at both ends via a support mechanism. The upper surface of the lower roller support is connected to the upper roller support via two symmetrically distributed adjusting clamping mechanisms. Each adjusting clamping mechanism includes a clamping hydraulic cylinder and a cylinder connecting plate. The cylinder connecting plate is fixedly connected to both ends of the upper surface of the lower roller support. The upper roller support is located directly above the lower roller support. An upper oil removal roller is rotatably connected between the inner walls of the two sides of the upper roller support. A clamping hydraulic cylinder is fixedly installed at both ends of the upper surface of the upper roller support. The output end of the clamping hydraulic cylinder passes through the inner wall of the upper roller support and is fixedly connected to the top of the cylinder connecting plate. A side limiting mechanism is connected between the upper roller support and the lower roller support.

[0010] As a further embodiment of this utility model: the support mechanism includes a sleeve, a spring and a mounting cylinder. The sleeve is fixedly connected to the upper surface of the base, the spring is connected to the lower inner wall of the sleeve, the mounting cylinder is connected to the top of the spring, and the mounting cylinder is fixedly connected to the lower roller support.

[0011] As a further embodiment of this utility model, a rubber pad is fixedly connected to the lower surface of the base.

[0012] As a further embodiment of this utility model: the side limiting mechanism includes a side mounting plate and a limiting plate. The front end face of the side mounting plate is fixedly connected to the limiting plate. The side mounting plate is fixedly connected to the support surface. Sliding grooves are provided on the left side of both the upper roller support and the lower roller support. The side mounting plate is slidably connected to the sliding grooves.

[0013] As a further embodiment of this utility model: a telescopic rod is connected between the mounting cylinder and the sleeve, the bottom end of the telescopic rod is rotatably connected to the sleeve, and the top end of the telescopic rod is threadedly connected to the mounting cylinder.

[0014] As a further embodiment of this utility model: the clamping force of the upper and lower degreasing rollers on the strip is achieved by adjusting the hydraulic pressure of the clamping hydraulic cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention achieves precise, uniform, and adjustable degreasing clamping force on the strip by adjusting the clamping mechanism. By introducing or discharging hydraulic oil into the clamping hydraulic cylinder, the piston extension and retraction of the hydraulic cylinder can be controlled, thereby changing the relative distance between the upper roller support and the lower roller support. Since the upper degreasing roller is rotatably connected between the inner walls on both sides of the upper roller support, and the lower roller support is connected to the lower degreasing roller, the force of the hydraulic cylinder is ultimately manifested as the clamping force applied by the upper and lower degreasing rollers to the strip passing between them.

[0017] This invention, through the structure of the spring-supported mounting cylinder and the lower roller support, enables the lower degreasing roller and its support to have elastic floating capability in the vertical direction. When the device is subjected to a vertical force, the spring will compress or rebound, thereby allowing the lower roller support and the lower degreasing roller to buffer and move up and down within a certain range, which helps to cope with minor changes or impacts in the position of the strip line during the rolling process.

[0018] This invention features a telescopic rod connecting the mounting cylinder and the sleeve. By rotating the telescopic rod, the thread feed depth within the mounting cylinder is changed, thereby adjusting the relative vertical position of the mounting cylinder to the sleeve. Since the spring is positioned between the sleeve and the mounting cylinder, this adjustment process essentially changes the compression of the support spring, i.e., adjusts the preload of the support spring. By adjusting the preload of the support spring, the entire floating unit consisting of the upper and lower degreasing rollers and the support can move up and down as a whole. This allows the clamping surfaces of the lower degreasing roller and the upper degreasing roller mating below it to be easily adjusted to the basic rolling line position, providing a means to adapt to different strip thicknesses or adjust the working height of the device.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-2 In this embodiment of the utility model, a floating synchronous oil removal device includes a lower roller support 4, a base 1, an upper roller support 9, and a side limiting mechanism.

[0024] The lower oil removal roller 5 is rotatably connected between the inner walls of both sides of the lower roller support 4. The lower surface of the lower roller support 4 is connected to the base 1 at both ends through a support mechanism. The support mechanism includes a sleeve 2, a spring 3 and a mounting cylinder 7. The sleeve 2 is fixedly connected to the upper surface of the base 1. The spring 3 is connected to the lower inner wall of the sleeve 2. The mounting cylinder 7 is fixedly connected to the top of the spring 3. The mounting cylinder 7 is fixedly connected to the lower roller support 4. A telescopic rod 6 is connected between the mounting cylinder 7 and the sleeve 2. The bottom end of the telescopic rod 6 is rotatably connected to the sleeve 2. The top end of the telescopic rod 6 is threadedly connected to the mounting cylinder 7. A rubber pad is fixedly connected to the lower surface of the base 1. The rubber pad can provide a certain shock absorption and buffering effect, reduce the transmission of vibration generated during equipment operation to the foundation, and may also play a role in anti-slip and stability, ensuring the stability of the bottom support of the entire device.

[0025] It should be noted that the structure of the mounting cylinder 7 and the lower roller support 4 supported by the spring 3 enables the lower degreasing roller 5 and its support to have elastic floating capability in the vertical direction. When the device is subjected to a vertical force, the spring 3 will compress or rebound, thereby allowing the lower roller support 4 and the lower degreasing roller 5 to buffer and move up and down within a certain range, which helps to cope with the slight changes or impacts in the position of the strip line during the rolling process.

[0026] Furthermore, a telescopic rod 6 is connected between the mounting cylinder 7 and the sleeve 2. By rotating the telescopic rod 6, the thread feed depth within the mounting cylinder 7 is changed, thereby adjusting the relative vertical position of the mounting cylinder 7 relative to the sleeve 2. Since the spring 3 is located between the sleeve 2 and the mounting cylinder 7, this adjustment process essentially changes the compression of the support spring 3, that is, it adjusts the preload of the support spring 3. By adjusting the preload of the support spring 3, the entire floating unit consisting of the upper and lower degreasing rollers and the support can move up and down as a whole. This allows the clamping surfaces of the lower degreasing roller 5 and the upper degreasing roller 8 that mates with it to be easily adjusted to the basic rolling line position, providing a means to adapt to different strip thicknesses or adjust the working height of the device.

[0027] The upper surface of the lower roller support 4 is connected to the upper roller support 9 by two symmetrically distributed adjusting clamping mechanisms. The adjusting clamping mechanism includes a clamping hydraulic cylinder 10 and a cylinder connecting plate 12. The cylinder connecting plate 12 is fixedly connected to both ends of the upper surface of the lower roller support 4. The upper roller support 9 is located directly above the lower roller support 4. The upper degreasing roller 8 is rotatably connected between the inner walls of the two sides of the upper roller support 9. The clamping hydraulic cylinder 10 is fixedly installed at both ends of the upper surface of the upper roller support 9. The output end of the clamping hydraulic cylinder 10 passes through the inner wall of the upper roller support 9 and is fixedly connected to the top end of the cylinder connecting plate 12. The clamping force of the upper degreasing roller 8 and the lower degreasing roller 5 on the strip is achieved by adjusting the hydraulic pressure of the clamping hydraulic cylinder 10.

[0028] It should be noted that a precise, uniform, and adjustable degreasing clamping force is applied to the strip by adjusting the clamping mechanism. By introducing or discharging hydraulic oil into the clamping hydraulic cylinder 10, the piston extension and retraction of the hydraulic cylinder can be controlled, thereby changing the relative distance between the upper roller support 9 and the lower roller support 4. Since the upper degreasing roller 8 is rotatably connected between the inner walls of the two sides of the upper roller support 9, and the lower roller support 4 is connected to the lower degreasing roller 5, the force of the hydraulic cylinder 10 is ultimately manifested as the clamping force applied by the upper degreasing roller 8 and the lower degreasing roller 5 to the strip passing between them.

[0029] Because two symmetrically distributed clamping hydraulic cylinders 10 are used to connect the upper and lower roller supports, and the hydraulic system can usually provide a stable pressure output, this ensures that the clamping force applied by the upper degreasing roller 8 and the lower degreasing roller 5 to the upper and lower surfaces of the strip is basically uniform along the length of the roller. Compared with the traditional single-sided pressurization or independent upper and lower adjustment scheme, this uniformity improves the degreasing effect and reduces the residue of local oil stains.

[0030] It should be noted that by adjusting the working pressure of the hydraulic system, the clamping force can be precisely controlled. This adjustability allows the device to flexibly adapt to the degreasing needs of strips of different materials and thicknesses, and to optimize the degreasing process parameters for different types and viscosities of rolling oil, thereby achieving the best degreasing effect.

[0031] A side limiting mechanism is connected between the upper roller support 9 and the lower roller support 4. The side limiting mechanism includes a side mounting plate 11 and a limiting plate 13. The front end face of the side mounting plate 11 is fixedly connected to the limiting plate 13. The side mounting plate 11 is fixedly connected to the support surface. A sliding groove is provided on the left side of both the upper roller support 9 and the lower roller support 4. The side mounting plate 11 is slidably connected to the sliding groove.

[0032] It should be noted that the side limiting mechanism provides lateral guidance and limiting for the floating unit consisting of the upper and lower roller supports and the degreasing roller, ensuring that the floating unit can move stably in the vertical direction as it moves up and down with the strip rolling line, preventing significant lateral swaying or skew, thereby ensuring that the clamping force can be applied evenly and effectively to the strip, further improving the stability and reliability of degreasing.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
