Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, specifically a cold rolling mill for processing metal sheets. Background Technology

[0002] Metal sheets are flat, rectangular materials made of metal and used in the construction industry as components for walls, ceilings, or floors. They are mainly classified into thin plates, medium plates, thick plates, and extra-thick plates. During the processing of metal sheets, they often need to be rolled using a cold rolling mill according to the actual usage.

[0003] The two rolls of the existing cold rolling mill are fixed in position and cannot be moved. During the rolling process, the thickness of the metal sheet is usually controlled by adjusting the distance between the two rolls. The adjustment process requires disassembling and reinstalling the two rolls, which is time-consuming and labor-intensive. It is not possible to quickly adjust the rolls according to production needs, which is inconvenient for users. At the same time, during the rolling process, the two rolls come into contact with the workpiece and bear huge pressure and friction, generating a lot of heat. Overheating may cause changes or softening of the surface material of the rolls, which in turn affects the surface quality of the rolled metal sheet. Utility Model Content

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0024] like Figures 1-7 As shown, a cold rolling mill for processing metal sheets includes: a cabinet 1, a base plate 11 fixedly connected to the top of the cabinet 1, two mounting frames 12 fixedly connected to the top of the base plate 11, an upper roll 13 and a lower roll 14 disposed between the two mounting frames 12; an adjustment assembly, which is respectively disposed on the two mounting frames 12 for adjusting the distance between the upper roll 13 and the lower roll 14; and a cooling assembly, which is disposed on the two cabinets 1 for cooling the upper roll 13 and the lower roll 14.

[0025] Among them, two mobile mounting platforms 211 are respectively fixedly mounted with motors 212, and the two motors 212 are respectively connected to the rotating shafts of the adjacent ends of the upper roll 13 and the lower roll 14.

[0026] When rolling a metal sheet, the distance between the upper roll 13 and the lower roll 14 is adjusted by the adjusting component according to the required thickness of the metal sheet. The workpiece is placed between the upper roll 13 and the lower roll 14. Then, two motors 212 are started. After the two motors 212 are started, they drive the upper roll 13 and the lower roll 14 to rotate relative to each other, winding the workpiece so that it passes between the upper roll 13 and the lower roll 14. Due to the pressure, the workpiece becomes thinner and its length increases. Subsequently, the metal sheet is trimmed to the required size. The cooling component can cool the upper roll 13 and the lower roll 14 to prevent them from overheating. Example 2

[0027] Based on Embodiment 1, the adjustment assembly includes: a mounting platform 2, a stepper motor 21, a screw 22, a screw block 23, a guide block 24, a moving block 25, and a guide groove 26. Mounting platforms 2 are fixedly mounted inside each of the two mounting frames 12. A stepper motor 21 is fixedly mounted on each mounting platform 2. A screw 22 is fixedly connected to one end of the drive shaft of the stepper motor 21. A trapezoidal screw block 23 is threaded onto the outside of the screw 22. Guide blocks 24 are fixedly connected to the two opposite inclined surfaces of the screw block 23. Two cooperating moving blocks 25 are provided at the top and bottom of the screw block 23. Guide grooves 26 are respectively opened on the two opposite inclined surfaces of the two moving blocks 25. Two partition plates 27 are fixedly connected inside each of the two mounting frames 12. The two moving blocks 25 located on the same side are respectively positioned... Between the two partition plates 27, a limiting groove 28 for the movement of the screw block 23 is provided on one side of the partition plate 27 near the mounting platform 2. One end of the screw 22 is rotatably connected to the partition plate 27 near the center position. Two moving grooves 29 are provided on the two partition plates 27 respectively. Through holes 210 are provided on the moving blocks 25 respectively. The rotating shafts of the upper roller 13 and the lower roller 14 at opposite ends pass through the through holes 210 and the moving grooves 29 respectively. Moving mounting platforms 211 are provided inside the two mounting frames 12 respectively. The two moving mounting platforms 211 are staggered. Two support springs 213 are fixedly connected to the bottom of the two mounting frames 12. The two support springs 213 are located between the two partition plates 27 respectively. The top ends of the two support springs 213 are connected to the two moving blocks 25 located at the bottom respectively.

[0028] When adjusting the distance between the upper roll 13 and the lower roll 14, two stepper motors 21 are started respectively. The stepper motors 21 drive the screw 22 to rotate. The rotation of the screw 22 engages with the screw block 23 and causes movement. By controlling the rotation direction of the stepper motors 21, the movement direction of the screw block 23 is controlled. By controlling the relative movement of the two screw blocks 23, the screw blocks 23 drive the two external guide blocks 24 to move inside the guide groove 26 of the moving block 25, thereby squeezing the two moving blocks 25 apart and causing them to move in opposite directions. When the two moving blocks 25 at the bottom move downward, they compress the support spring 213, causing it to contract and store energy. The two moving blocks 25 drive the upper roll 13 and the lower roll 14 to separate, thereby widening the distance between the upper roll 13 and the lower roll. The distance between the upper and lower rollers 13 and 14 is reduced by controlling the two screw blocks 23 to move in opposite directions. Since the guide block 24 and guide groove 26 are arranged in a trapezoidal structure, they will drive the two moving blocks 25 to move relative to each other, thereby reducing the distance between the upper and lower rollers 13 and 14. The support spring 213 supports the two moving blocks 25 located at the bottom and assists the two moving blocks 25 located at the bottom to move upward under the action of the elastic force. When the upper roller 13 and lower roller 14 move, their rotation axis moves along the moving groove 29. The two partition plates 27 can restrict the moving blocks 25 so that the moving blocks 25 can only move between the two partition plates 27. The through hole 210 can accommodate the rotation of the rotation axis of the upper roller 13 and lower roller 14. Example 3

[0029] Based on Embodiment 1, the cooling assembly includes: an air pump 3, an air pipe 31, an air knife 32, and an air duct 33. The air pump 3 is installed inside the cabinet 1. One end of the air pump 3 is fixedly connected to the air pipe 31. An air knife 32 is fixedly installed between the top and bottom of the two mounting frames 12, respectively. The two air knives 32 are arranged opposite to each other and are aligned with the upper roller 13 and the lower roller 14. The air pipe 31 is connected to the two air knives 32 respectively. Three air ducts 33 are opened on both the upper roller 13 and the lower roller 14. The three air ducts 33 are arranged in a spiral structure. The two opposite ends of the three air ducts 33 are respectively connected to the outside.

[0030] During processing, the air pump 3 is started to deliver high-speed airflow into the air pipe 31. The high-speed airflow is blown out from the two air knives 32 that are set opposite each other, and blows on the upper roll 13 and the lower roll 14 to cool them down. When the upper roll 13 and the lower roll 14 rotate, one end of the three air channels 33 is opposite to the high-speed airflow. The ejected high-speed airflow enters the air channel 33 and carries away the internal heat when it flows in the air channel 33, thereby improving the cooling efficiency of the upper roll 13 and the lower roll 14 and thus preventing the upper roll 13 and the lower roll 14 from overheating.
