Metal rolling mill and metal sheet rolling method for rotor sheet production

Abstract

The invention relates to the technical field of metal sheet rolling, and discloses a metal rolling mill and a metal sheet rolling method used in rotor sheet production. When position deviation occurs during the transfer of a metal plate, the metal plate drives a detection ring to move, and the movement of the detection ring produces a position change. The alignment detectors on both sides detect the position change of the detection ring, and the alignment detectors on both sides control the sliding member to move, so that the sliding member moves the same position according to the position change of the detection ring, and the sliding member drives the roller to move, thereby offsetting the position deviation of the metal plate. Therefore, during the transfer of the metal plate to the metal rolling mill, if alignment deviation occurs, the position of the metal plate sent to the roller is incorrect, and even when the metal plate is transferred to the edge positions of both ends of the roller, the detection ring automatically detects the relative position of the metal plate and the roller, and automatically calibrates the relative position of the metal plate and the roller, thereby ensuring the position accuracy of the metal plate after being transferred into the metal rolling mill, and improving the stability of the operation of the metal rolling mill.

[0002] A rolling mill is a device used to realize the metal rolling process. In a broad sense, it refers to the equipment that completes the entire process of rolling production. A common rolling mill is mainly composed of rollers, frames, roll gap adjustment devices, roll temperature adjustment devices, transmission devices, lubrication systems, control systems, and roll removal devices.

[0003] In existing metal rolling mills, such as Chinese patent application CN118162465A, cooling water is brought into contact with the rollers and metal plates under the action of atmospheric pressure to remove heat, thereby improving the cooling effect of the rolling mill, cleaning the rollers and metal plates, and ensuring that the rolled metal plates have good surface quality. The used cooling water is filtered, and the filtered cooling water in the filter box is intermittently discharged to achieve the effect of cleaning the filter screen. At the same time, the water pump is started intermittently, which not only sends the cooling water back to the water storage tank for reuse, but also reduces energy consumption.

[0004] However, there are still the following problems: when the metal plate is transported to the rolling mill for rolling, if the transportation of the metal plate is offset, it will cause deviations in the alignment of the metal plate and the rolling mill, and then cause the processing position of the metal plate to deviate from the working position of the rolling mill, resulting in a large number of unqualified products. Summary of the invention

[0017] Compared with the prior art, the present invention provides a metal rolling mill having the following beneficial effects:

[0018] 1. The metal rolling mill starts the rollers, transfers the metal plate through the detection ring to between the rollers, and the rollers roll the metal plate. At the same time, the roller group is used to clamp and press the rollers to prevent the rollers from loosening due to the reaction force generated when the rollers roll the metal plate, thereby reducing the rolling quality.

The alignment detectors on both sides detect the position change of the detection ring. The alignment detectors on both sides control the sliding member to move, so that the sliding member moves the same position according to the position change of the detection ring. The sliding member drives the roller to move, thereby offsetting the position deviation of the metal plate. Therefore, during the transfer of the metal plate to the metal rolling mill, if the alignment deviation occurs, the position of the metal plate sent to the roller is incorrect, and even when the metal plate is transferred to the edge positions of both ends of the roller, the detection ring is automatically aligned to detect the relative position of the metal plate and the roller, and the relative position of the metal plate and the roller is automatically detected and calibrated to ensure the position accuracy of the metal plate after it is transferred into the metal rolling mill, thereby improving the stability of the operation of the metal rolling mill.

[0019] 2. The metal rolling mill, through the setting of the spring, can always position the detection ring in the middle due to the elastic action of the spring when the metal rolling mill is not rolling, ensuring that each time the metal rolling mill is restarted, as long as the metal plate does not shift in position, the metal rolling mill does not need to be manually debugged, thereby further improving the stability of the rolling mill operation.

[0020] 3. The metal rolling mill, through the setting of the guide plate, can guide the metal plate into the detection ring each time the metal plate re-enters the detection ring, thereby reducing the workers' operation items, simplifying the operation steps of the metal rolling mill, making it convenient for workers to operate the metal rolling mill, and indirectly improving the working quality of the metal rolling mill.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a metal rolling mill and a metal sheet rolling method for rotor sheet production.

[0032] Example 1

[0033] In a typical implementation of the present application, Figure 1 As shown, a metal rolling mill comprises a frame 1, a rolling mechanism 2 arranged on the frame 1, and an auxiliary mechanism 3 arranged on the rolling mechanism 2, wherein the rolling mechanism 2 comprises a rolling roller 21 and a pressure roller group 200, wherein the rolling roller 21 is arranged on the frame 1, and the rolling roller 21 is divided into two parts, which are symmetrically distributed, and the upper and lower parts of the rolling roller 21 are arranged adjacent to each other, and the space between the upper and lower parts of the rolling roller 21 is used for rolling metal plates, and the pressure roller group 200 is arranged on the frame 1, and the pressure roller group 200 is divided into two parts, which are symmetrically distributed, and the rolling roller 21 is located between the upper and lower parts of the pressure roller group 200, and the upper part of the pressure roller group 200 is in contact with the upper part of the rolling roller 21, and the lower part of the pressure roller group 200 is in contact with the lower part of the rolling roller 21, and the pressure roller group 200 is used for applying pressure to the rolling roller 21;

[0034] The auxiliary mechanism 3 includes a sliding member 32, a detection ring 36, and two-side alignment detectors 38. The sliding member 32 is slidably arranged on the frame 1, and the roller 21 is arranged on the sliding member 32. The detection ring 36 is movably arranged on the frame 1. The detection ring 36 and the roller 21 are located at the same height. The detection ring 36 is located on the path where the metal plate is transferred. The two-side alignment detectors 38 are fixedly installed on the frame 1. The two-side alignment detectors 38 are used to detect the relative positions of the sliding member 32 and the detection ring 36 on both sides of the two-side alignment detectors 38. When the position of the detection ring 36 changes, the two-side alignment detectors 38 control the sliding member 32 to move in the same way.

[0035] When using the present invention:

[0036] The roller 21 is started, and the metal plate is transferred between the rollers 21 through the detection ring 36. The roller 21 rolls the metal plate, and the roller group 200 is used to clamp and press the roller 21 to prevent the reaction force generated by the roller 21 when rolling the metal plate from causing the roller 21 to loosen and reduce the rolling quality. When a position deviation occurs during the transfer of the metal plate, the metal plate drives the detection ring 36 to move, and the movement of the detection ring 36 causes a position change. The alignment detectors 38 on both sides detect the position change of the detection ring 36, and the alignment detectors 38 on both sides control the sliding member 32 to move. The sliding member 32 is moved in the same position according to the position change of the detection ring 36. The sliding member 32 drives the roller 21 to move, so as to offset the position deviation of the metal plate. Therefore, during the process of the metal plate being transferred to the metal rolling mill, if there is a positioning deviation, the position of the metal plate sent to the roller 21 is incorrect, and even when the metal plate is transferred to the edge positions of both ends of the roller 21, the detection ring 36 will automatically detect the relative position of the metal plate and the roller 21, and automatically calibrate the relative position, thereby ensuring the position accuracy of the metal plate after being transferred into the metal rolling mill and improving the stability of the operation of the metal rolling mill.

[0049] The overall working principle of a metal rolling mill:

[0050] The roller 21 is started, and the metal plate is transferred between the rollers 21 through the detection ring 36. The roller 21 rolls the metal plate, and the roller group 200 is used to clamp and press the roller 21 to prevent the reaction force generated by the roller 21 when rolling the metal plate from causing the roller 21 to loosen and reduce the rolling quality. When a position deviation occurs during the transfer of the metal plate, the metal plate drives the detection ring 36 to move, and the movement of the detection ring 36 causes a position change. The alignment detectors 38 on both sides detect the position change of the detection ring 36, and the alignment detectors 38 on both sides control the sliding member 32 to move. The sliding member 32 is moved in the same position as the position change of the detection ring 36, and the sliding member 32 drives the roller 21 to move, so as to offset the position deviation of the metal plate. Therefore, in the process of transferring the metal plate to the metal rolling mill, if there is a position deviation, the position of the metal plate sent to the roller 21 is incorrect, and even when the metal plate is transferred to the edge positions of both ends of the roller 21, the detection ring 36 automatically detects the relative position of the metal plate and the roller 21, and automatically calibrates the relative position, thereby ensuring the position accuracy of the metal plate after being transferred into the metal rolling mill, and improving the stability of the operation of the metal rolling mill;

The wheel 29 drives the first screw 27 to rotate, and the first screw 27 drives the pressure cap 28 to move downward, so that the pressure cap 28 presses the moving frame 25 to move downward, and the moving frame 25 presses the rail frame 24 to move downward, so that the moving frame 25 drives the upper pressure roller 26 to press the roller 21, and the lower pressure roller 22 cooperates with the reaction thrust of the buffer pressure rod 23 to press the roller 21, so that the upper pressure roller 26 and the lower pressure roller 22 clamp and press the roller 21 as a whole, so as to avoid the roller 21 from loosening when rolling the metal plate, and ensure the stability of the metal plate rolling process;

[0052] When the transferred metal plate has a position deviation, the metal plate drives the detection ring 36 to move, and the detection ring 36 presses the telescopic rod 35 to adaptively extend and retract, and the detection ring 36 drives the first positioning detection plate 39 to move, and the alignment detectors 38 on both sides detect that the position of the first positioning detection plate 39 is offset, and the alignment detectors 38 on both sides control the third motor 314 to start, and the third motor 314 drives the single auxiliary gear 312 to rotate, and the single auxiliary gear 312 drives the toothed belt 313 to rotate, and the toothed belt 313 drives the overall auxiliary gear 312 to rotate, and the auxiliary gear 312 drives the second screw 311 to rotate, and the second screw 311 drives the sliding member 32 to move on the slide rail 31, and the sliding member 32 drives the second positioning detection plate 310 to move, so that the movement of the second positioning detection plate 310 is the same as the movement of the first positioning detection plate 39, and then the alignment detectors 38 on both sides control the third motor 314 to stop running, so that the roller 21 is automatically adapted to the position deviation of the metal plate.
