Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, and in particular to a support platform for a cold rolling mill for aluminum coils with quick roll changing. Background Technology

[0002] A cold rolling mill is a new type of equipment for cold rolling steel bars. This machine can process hot-rolled wire rods and hot-rolled coils with diameters between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with finished diameters between 5 mm and 12 mm. Cold-rolled ribbed steel bars produced by a cold rolling mill are a replacement product for cold-drawn low-carbon steel wire in prestressed concrete components. In cast-in-place concrete structures, they can replace Grade I steel bars to save steel. They are one of the better types of cold-processed steel products.

[0003] Existing cold rolling mill support platforms have some shortcomings in use. Although existing cold rolling mills can perform roll changing operations, under some high-precision rolling requirements after roll changing, the existing positioning devices may not be able to completely guarantee the relative stability of the roll installation, resulting in certain fluctuations in the dimensional accuracy and plate shape quality of the rolled products. This affects the processing operation of aluminum coils and reduces the installation accuracy of the rolls. To address the above problems, an improved and upgraded support platform for aluminum coil cold rolling mills with quick roll changing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a support platform for a cold rolling mill of aluminum coil with quick roll changing, so as to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a support platform for a cold rolling mill of aluminum coil with quick roll changing, including a support base plate. A cold rolling mill frame is fixedly installed on the upper surface of the support base plate. A lower cold rolling roll and an upper cold rolling roll are respectively installed inside the cold rolling mill frame. A limit roller shaft is installed inside the lower cold rolling roll. One end of the limit roller shaft is installed inside the mounting sleeve, and the mounting sleeve is fixedly connected to the outer wall of the cold rolling mill frame. Mounting structures are provided on both sides of the mounting sleeve. The mounting structure includes a fixing frame fixedly installed on both sides of the outer wall of the cold rolling mill frame. A drive motor is fixedly installed at one end of the fixing frame, and a threaded rod is fixedly connected to the output end of the drive motor. A limit plug plate is threadedly connected to the outer wall of the threaded rod, and one end of the limit plug plate is snapped onto the limit roller shaft.

[0006] As a preferred embodiment of the above technical solution, the lower cold rolling roll is fixedly placed on two electric support platforms of the same size. The bottom of each electric support platform is connected to two guide pulleys, and the guide pulleys rotate in contact with two sets of guide rails.

[0007] As a preferred embodiment of the above technical solution, both guide rails are fixedly installed on the support base plate, and two telescopic cylinders are fixedly installed on one side of the cold rolling mill frame, with a guide locking block fixedly connected to one end of each telescopic cylinder.

[0008] As a preferred embodiment of the above technical solution, the two guide locking blocks are inserted into the limiting roller shaft, and two symmetrical hydraulic cylinders are fixedly installed inside the cold rolling mill frame, with one end of each hydraulic cylinder fixedly connected to the bearings at both ends of the upper cold rolling roll.

[0009] As a preferred embodiment of the above technical solution, the upper and lower ends of the fixing frame are provided with guide grooves, and the upper and lower ends of the limiting plug plate are fixedly connected with guide blocks, which are slidably disposed in the guide grooves.

[0010] As a preferred embodiment of the above technical solution, the two guide blocks are internally slidably connected to the outer wall of the guide slide rod, both ends of the two guide slide rods are fixedly connected to two sets of mounting seats, and the mounting seats are fixedly installed on the fixed frame. The limiting plug plate passes through the inside of the mounting sleeve and its extension end is engaged inside the limiting roller shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device includes components such as a telescopic cylinder, a guide locking block, a fixing frame, a drive motor, a limit plug-in plate, and a guide slide rod. By replacing the cold rolling roll, the drive motor drives the limit plug-in plate to slide on the guide slide rod using the guide block, causing the limit plug-in plate to lock and limit the upper limit roller shaft of the cold rolling roll. At the same time, the telescopic cylinder drives the guide locking block to limit and fix the other end of the limit roller shaft, effectively reducing the installation error of the roll and improving the installation stability of the cold rolling roll. In addition, the device is equipped with a guide slide rail, guide pulley, and electric support platform to facilitate the quick replacement of the cold rolling roll and avoid the time-consuming and labor-intensive problems caused by manual loading and unloading.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1 to 4 As shown in the figure, this embodiment provides a support platform for a fast roll change aluminum coil cold rolling mill, including a support base plate 1. A cold rolling mill frame 2 is fixedly installed on the upper surface of the support base plate 1. A lower cold rolling roll 4 and an upper cold rolling roll 7 are respectively installed inside the cold rolling mill frame 2. A limit roller shaft 8 is installed inside the lower cold rolling roll 4. One end of the limit roller shaft 8 is installed inside the mounting sleeve 11 and the mounting sleeve 11 is fixedly connected to the outer wall of the cold rolling mill frame 2. Mounting structures 5 are provided on both sides of the mounting sleeve 11. The mounting structure 5 includes a fixing frame 52 fixedly installed on both sides of the outer wall of the cold rolling mill frame 2. A drive motor 51 is fixedly installed on one end of the fixing frame 52 and a threaded rod 54 is fixedly connected to the output end of the drive motor 51. A limit plug plate 53 is threadedly connected to the outer wall of the threaded rod 54. One end of the limit plug plate 53 is snapped onto the limit roller shaft 8.

[0017] like Figures 2 to 3 As shown, the lower cold rolling roll 4 is fixedly placed on two electric support platforms 6 of the same size. The bottom of each electric support platform 6 is connected to two guide pulleys 61, and the guide pulleys 61 rotate on two sets of guide rails 3. The two guide rails 3 are fixedly installed on the support base plate 1. Two telescopic cylinders 10 are fixedly installed on one side of the cold rolling mill frame 2, and one end of the telescopic cylinder 10 is fixedly connected to a guide locking block 101. The two guide locking blocks 101 are inserted into the limit roller shaft 8. Two symmetrical hydraulic cylinders 9 are fixedly installed inside the cold rolling mill frame 2. One end of the two hydraulic cylinders 9 is fixedly connected to the bearings at both ends of the upper cold rolling roll 7.

[0018] By driving two hydraulic cylinders 9, the upper cold rolling roll 7 is moved downward, causing the upper cold rolling roll 7 and the lower cold rolling roll 4 to move closer to each other, which facilitates the cold rolling process of aluminum coil. At the same time, the bottom guide pulleys 61 of the two sets of electric support platforms 6 are matched with the guide rails 3 to facilitate the stable movement of the lower cold rolling roll 4 for replacement. Two telescopic cylinders 10 are set to limit the lower cold rolling roll 4 when it moves to the appropriate position.

[0019] like Figure 4 As shown, the upper and lower ends of the fixed frame 52 are provided with guide grooves 58. The upper and lower ends of the limiting plug plate 53 are fixedly connected with guide blocks 56, and the guide blocks 56 are slidably disposed in the guide grooves 58. The two guide blocks 56 are slidably connected to the outer wall of the guide rod 55. The two guide rods 55 are fixedly connected to two sets of mounting seats 57 at both ends, and the mounting seats 57 are fixedly installed on the fixed frame 52. The limiting plug plate 53 passes through the inside of the mounting sleeve 11 and its extended end is engaged inside the limiting roller shaft 8.

[0020] By using two guide blocks 56 to slide on the guide slide rod 55, the limiting plug plate 53 is relatively stable when the threaded rod 54 drives the limiting plug plate 53 to move, avoiding problems such as misalignment between the limiting plug plate 53 and the groove of the mounting sleeve 11 when moving.

[0021] The working principle and process of this utility model are as follows: When it is necessary to replace the cold rolling rolls in the cold rolling mill, the replacement cold rolling roll is first placed on two electric support platforms 6 using a crane. Then, the external power supply is connected, and the lower guide pulley 61 is driven to slowly move along the guide rail 3, so that one end of the limiting roller shaft 8 inside the lower cold rolling roll 4 passes through the inside of the mounting sleeve 11 for precise alignment. The insertion hole inside the limiting roller shaft 8 is aligned with the slot inside the mounting sleeve 11. At this time, the two fixed brackets 52 are driven to... When the drive motor 51 operates, it causes the limit plug-in plate 53 on the outer wall of the threaded rod 54 to move along the direction of the guide groove 58. This causes one end of the two limit plug-in plates 53 to pass through the inside of the mounting sleeve 11 and lock the limit roller shaft 8 in place. At the same time, the drive telescopic cylinder 10 drives the guide locking block 101 to limit the other end of the limit roller shaft 8. The principle is the same in reverse. This allows for the disassembly of the lower cold rolling roll 4, facilitating the quick replacement of the cold rolling roll while ensuring a relatively tight installation, thus improving the installation stability of the cold rolling roll.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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.
