Description

Technical Field

[0001] This utility model relates to the field of cold rolling technology, specifically to a roll for a cold rolling mill with a cleaning structure. Background Technology

[0002] Cold rolling is a process in which steel billets are continuously cold-deformed at room temperature. During the cold rolling process, the steel undergoes strong plastic deformation, which can improve the strength of the steel. The cold rolling process is carried out by a cold rolling mill. The rolls are the middle part of the cold rolling mill. In order to avoid the residual impurities on the outer surface of the workpiece and affect the product forming, rolls with cleaning structures are installed.

[0003] For example, Chinese utility model patent CN218903093U discloses a roll for a cold rolling mill with a rapid cleaning structure. The roll includes a frame, a housing on the frame, and a cleaning mechanism inside the housing. The cleaning mechanism includes a motor mounted on the top of the housing, a main pulley at the motor output end, a rotating column inside the housing, and auxiliary pulleys outside the rotating column. A belt connects the main pulley and the auxiliary pulleys, driving the rotation. A rotating shaft is mounted on the rotating column, passing through the housing and extending downwards. A brush disc is located at the bottom of the rotating shaft. When the workpiece is pushed into the cold rolling mill, the motor is started, driving the main pulley to rotate. The main pulley and multiple sets of auxiliary pulleys are driven by belts, synchronously driving multiple sets of brush discs. The high-speed rotation of the brush discs cleans the surface of the workpiece. This solution has a novel structure, is easy to operate, and can be added separately to the cold rolling mill without manual cleaning, saving time and labor, meeting practical needs, and improving practicality.

[0004] However, existing cold rolling mill rolls with cleaning structures are inconvenient for cleaning both the workpiece and the rolls simultaneously, and are also inconvenient for disassembling and assembling the rolls. Therefore, we propose a cold rolling mill roll with a cleaning structure to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] Example 1: Please refer to Figures 1-7 The existing cold rolling mill rolls with cleaning structures are inconvenient to clean both the workpiece and the rolls at the same time. In order to solve this technical problem, this embodiment discloses the following technical content;

[0030] A cold rolling mill roll with a cleaning structure includes a base 1, a motor 4, a lower roll 5, and an upper roll 7. Side plates 2 are vertically fixed to both the left and right ends of the upper surface of the base 1. Two sets of mounting plates 3 are installed inside the side plate 2 at the left end of the upper surface of the base 1. The motor 4 is fixed to the left side of the mounting plate 3. The lower roll 5 and the upper roll 7 are arranged inside the side plate 2. The right end of the lower roll 5 is connected to a first stop block 6, and the right end of the upper roll 7 is connected to a second stop block 8. The left ends of the lower roll 5 and the upper roll 7 are both rectangular. The lower roll 5 and the upper roll 7 are both engaged with the output shaft of the motor 4. The connection between the lower roll 5 and the first stop block 6 and the connection between the upper roll 7 and the second stop block 8 are both circular.

[0031] A positioning plate 12 is fixed to the rear side of the side plate 2 by screws. A connecting frame 13 is fixed to the rear of the first horizontal plate 9 and the second horizontal plate 10. A roller cleaning plate 15 is fixed to the inner side of the positioning plate 12. A workpiece cleaning plate 14 is fixed to the bottom of the connecting frame 13. A collection box 16 is provided below the workpiece cleaning plate 14.

[0032] Motor 4 drives the lower roller 5 and the upper roller 7 to rotate. The right ends of the lower roller 5 and the upper roller 7 rotate inside the first stop 6 and the second stop 8, respectively. The workpiece is processed by the rotation of the lower roller 5 and the upper roller 7. The rear sides of the lower roller 5 and the upper roller 7 are in contact with the brush on the roller cleaning plate 15. When the lower roller 5 and the upper roller 7 rotate, the roller cleaning plate 15 cleans the outer sides of the lower roller 5 and the upper roller 7, and the impurities fall into the collection box 16.

[0033] The workpiece cleaning plate 14 is fixedly connected to the roller cleaning plate 15 by a rod. The workpiece is located between the upper and lower two sets of workpiece cleaning plates 14. The upper and lower two sets of workpiece cleaning plates 14 clean the upper and lower surfaces of the workpiece.

[0034] The upper surface of the mounting plate 3 inside the side plate 2 is fixed with a second horizontal plate 10. The bottom ends of the second horizontal plate 10 and the first horizontal plate 9 are both equipped with the output end of the electric telescopic rod 11. The height of the first horizontal plate 9 and the second horizontal plate 10 is adjusted by the extension and retraction of the electric telescopic rod 11, thereby adjusting the distance between the upper roller 7 and the lower roller 5 as needed. When the upper roller 7 moves, the workpiece cleaning plate 14 and the roller cleaning plate 15 above move with the upper roller 7.

[0035] Example 2: Existing cold rolling mill rolls with cleaning structures are inconvenient to disassemble and assemble. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figure 1 , Figure 3 , Figure 6 and Figure 7 ;

[0036] The side plate 2 on the right end of the upper surface of the base 1 is fixedly connected to the first stop 6 by screws. The circular structure on the right end of the lower roller 5 is inserted into the interior of the first stop 6. The second stop 8 is fixed to the first horizontal plate 9 by screws. The circular structure on the right end of the upper roller 7 is inserted into the interior of the second stop 8. Remove the screws connecting the first stop 6 to the side plate 2 and the second stop 8 to the first horizontal plate 9. Then remove the first stop 6 and the second stop 8. Pull the lower roller 5 and the upper roller 7 outward. The distance between the front and rear walls of the rectangular groove inside the side plate 2 is greater than the diameter of the lower roller 5 and the upper roller 7. Thus, the lower roller 5 and the upper roller 7 can be pulled to the right inside the side plate 2, so that the lower roller 5 and the upper roller 7 are separated from the output shaft of the motor 4. The lower roller 5 and the upper roller 7 can then be removed.

[0037] The above completes a series of operations for the cold rolling mill rolls with the cleaning structure. Any content not described in detail in this specification is prior art known to those skilled in the art.
