Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, specifically to a centering adjustment mechanism for aluminum coil cold rolling mills. Background Technology

[0002] Cold rolling uses hot-rolled steel coils as raw materials, and after pickling to remove oxide scale, it is continuously cold rolled. The finished product is hard-rolled coil. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coil increase and the toughness and plasticity decrease. Therefore, the stamping performance will deteriorate, and it can only be used for parts with simple deformation.

[0003] There are two-roll mills, four-roll mills and multi-roll mills used for cold rolling. The most widely used is the four-roll mill. The forging rolls used in existing four-roll mills are in fixed positions, and the spacing and height of the forging rolls are difficult to change. In addition, because cold rolling requires a large pressure, the forging rolls are heavy, making replacement or maintenance quite complicated. Utility Model Content

[0004] The purpose of this invention is to provide a centering adjustment mechanism for an aluminum coil cold rolling mill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centering adjustment mechanism for an aluminum coil cold rolling mill, comprising multiple columns, with multiple columns on the same side forming a group, and two symmetrically arranged fixing plates fixedly installed between two adjacent columns. Two hydraulic rods are installed at one end of each of the two fixing plates facing each other, and a lifting rod is installed at the other end of the two hydraulic rods. The lifting rod is slidably connected to the two columns, and an active roller is rotatably connected between the two fixing plates on the same horizontal line. A cold rolling roll is rotatably connected above the active roller at a position between the two lifting rods.

[0006] Preferably, a linkage block is installed at both ends of the cold rolling roll, and a base is rotatably connected to the other end of the linkage block. The other end of the base is fixedly connected to the side end of the lifting rod.

[0007] Preferably, a fixing ring is installed at both ends of the drive roller, and a groove is formed on the surface of the fixing ring, the size of which is adapted to the size of the linkage block.

[0008] Preferably, the column has a groove on its surface facing the lifting rod, and a slider is installed at both ends of the lifting rod, the slider being slidably connected inside the groove.

[0009] Preferably, the surface of the drive roll and the surface of the cold rolling roll do not contact each other.

[0010] Preferably, a mounting ring plate is fixedly installed on the outer side of the fixing ring, and a plurality of fixing bolts are arrayed on the surface of the mounting ring plate.

[0011] Preferably, the fixing ring has multiple models with different thicknesses, while the size of the groove remains constant.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This aluminum coil cold rolling mill uses a centering adjustment mechanism. The columns provide separation and support. One end of the drive roller is connected to an external drive device, which drives the drive roller to rotate. The drive roller drives the cold rolling roller to rotate. There is a certain gap between the two cold rolling rollers. When the aluminum alloy passes between the two cold rolling rollers, it is squeezed. After multiple consecutive compressions by the cold rolling rollers, the aluminum alloy becomes an aluminum coil. The hydraulic rod can drive the lifting rod to move up and down, thereby changing the gap between the two lifting rods. This changes the gap between the two cold rolling rollers, making it convenient for users to process aluminum coils of different thicknesses.

[0014] 2. This aluminum coil cold rolling mill uses a centering adjustment mechanism. By installing fixed rings at both ends of the drive roll, and grooves on the surface of the fixed rings, the grooves fit into the linkage block. When the drive roll rotates, the fixed rings rotate synchronously, which in turn drives the linkage block to rotate. The linkage block drives the cold rolling roll to rotate, which avoids direct contact between the drive roll and the cold rolling roll. During replacement or maintenance, the cold rolling roll and the drive roll will not affect each other, making it convenient for users to perform maintenance or replacement.

[0020] 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.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not 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 this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 4 As shown, the centering adjustment mechanism for the aluminum coil cold rolling mill in this embodiment includes multiple columns 1. Multiple columns 1 on the same side form a group, and the multiple columns 1 are divided into two groups. Each group contains multiple columns 1. Two symmetrically arranged fixing plates 2 are fixedly installed between two adjacent columns 1. The fixing plates 2 are fixedly installed between two columns 1 in the same group. Two hydraulic rods 11 are installed at the opposite ends of the two fixing plates 2. Two hydraulic rods 11 are installed at the lower end of the upper fixing plate 2 and at the upper end of the lower fixing plate 2. The other ends of the two hydraulic rods 11 are connected by a lifting rod 12. The two lifting rods 12 do not contact each other. The lifting rods 12 and the two... The columns 1 are slidably connected, and the lifting rod 12 is slidably connected to the columns 1. Under the action of the hydraulic rod 11, it can move up and down within a certain range. The two fixed plates 2 on the same horizontal line are rotatably connected to the active roller 3. The cold rolling roller 4 is rotatably connected above the active roller 3 and located between the two lifting rods 12. One end of the active roller 3 is connected to a drive device, which is a common servo motor on the market. It is connected to an external power supply and can drive the active roller 3 to rotate. The two active rollers 3 can drive the two cold rolling rollers 4 to rotate. The two cold rolling rollers 4 can cold roll the aluminum alloy to make the aluminum alloy into aluminum coil.

[0023] Specifically, a linkage block 7 is installed at both ends of the cold rolling roll 4. A base 8 is rotatably connected to the other end of the linkage block 7. The other end of the base 8 is fixedly connected to the side end of the lifting rod 12. A fixing ring 9 is installed at both ends of the drive roll 3. A groove 10 is opened on the surface of the fixing ring 9. The size of the groove 10 is adapted to the size of the linkage block 7. By installing fixing rings 9 at both ends of the drive roll 3 and opening grooves 10 on the surface of the fixing rings 9, the grooves 10 fit with the linkage block 7. When the drive roll 3 rotates, the fixing rings 9 will rotate synchronously, thereby driving the linkage block 7 to rotate. The linkage block 7 drives the cold rolling roll 4 to rotate. This can avoid direct contact between the drive roll 3 and the cold rolling roll 4. When replacing or repairing, the cold rolling roll 4 and the drive roll 3 will not affect each other, which is convenient for users to repair or replace.

[0024] Furthermore, a groove 5 is provided on the surface of the column 1 facing the lifting rod 12, and a slider 6 is installed at both ends of the lifting rod 12. The slider 6 is slidably connected inside the groove 5. Through the slidable connection between the slider 6 and the groove 5, the lifting rod 12 can slide up and down between the two columns 1.

[0025] Furthermore, the surfaces of the drive roll 3 and the cold rolling roll 4 do not contact each other, and the drive roll 3 and the cold rolling roll 4 do not contact each other. During operation, if the drive roll 3 or the cold rolling roll 4 is damaged, it will not have a significant impact on other components, and the degree of damage can be reduced to a certain extent.

[0026] Furthermore, a mounting ring plate 13 is fixedly installed on the outer side of the fixing ring 9. Multiple fixing bolts 14 are arrayed on the surface of the mounting ring plate 13. The fixing ring 9 comes in various thickness sizes. The size of the groove 10 remains unchanged. Multiple fixing bolts 14 are threaded through the mounting ring plate 13 and the drive roller 3, thereby installing the fixing ring 9 at the surface edge of the drive roller 3. When the user needs to adjust the distance between the two cold rolling rollers 4, since the cold rolling rollers 4 need to be connected to the fixing ring 9 through the linkage block 7, the thickness of the fixing ring 9 also needs to be adjusted synchronously when adjusting the distance between the cold rolling rollers 4. Therefore, fixing rings 9 with different thickness sizes need to be prepared for replacement.

[0027] The usage method of this embodiment is as follows: the column 1 is set up to achieve the effect of separation and support. One end of the active roller 3 is connected to an external drive device. The external drive device drives the active roller 3 to rotate. The active roller 3 drives the cold rolling roller 4 to rotate. There is a certain gap between the two cold rolling rollers 4. When the aluminum alloy passes between the two cold rolling rollers 4, it will be squeezed. After multiple consecutive squeezing by multiple cold rolling rollers 4, the aluminum alloy will become an aluminum coil. The hydraulic rod 11 can drive the lifting rod 12 to move up and down, thereby changing the gap between the two lifting rods 12, so that the gap between the two cold rolling rollers 4 changes, which makes it convenient for users to process aluminum coils of different thicknesses.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
