Description

Technical Field

[0001] The utility model relates to the technical field of application of aluminum foil rolling mill equipment, in particular to a replacement device for a flattening roller of an aluminum foil rolling mill. Background Art

[0002] The flattening roller of the aluminum foil rolling mill is located inside the rolling mill arch. It is crucial to eliminate the air film under the action of the cylinder for the production of aluminum foil. However, due to long-term use, the convexity of the flattening roller will inevitably wear and tear, and it is difficult to meet the high-speed and high-quality production requirements of the aluminum foil rolling mill. Therefore, the flattening roller of the aluminum foil rolling mill needs to be replaced from time to time. However, at present, each replacement of the flattening roller is complicated and has a high safety risk. In addition, due to the obstruction of the rolling mill arch, the flattening roller cannot be directly lifted by the crane, resulting in a large workload for disassembling the aluminum foil rolling mill arch, and even inconvenient disassembly. At the same time, since the lifting and lowering path of the boom of the flattening roller saddle is in an arc state, the flattening roller support saddle must also move forward and backward with the lifting and lowering of the boom. When the new flattening roller is installed, it is difficult to align the left and right bearing boxes of the flattening roller with the boom mounting groove in time, and it is very easy to have misalignment and jamming, which brings many inconveniences to the replacement and installation. Therefore, due to the long time and time-consuming and labor-intensive replacement of the flattening roller, the production quality and efficiency of the aluminum foil rolling mill are usually low.

[0013] The utility model provides a replacement device for the flattening roller of an aluminum foil rolling mill, which is mainly composed of a trolley, a lifting guide column, an adjusting screw, a movable saddle and a slider. By moving the trolley to the position where the flattening roller needs to be disassembled and assembled, the hydraulic lifting cylinder is first used to lift the flattening roller support seat as a whole to a reasonable disassembly and assembly position, and then the first adjusting screw is engaged and rotated to adjust the front and rear position of the first movable saddle, so that the slider is moved as a whole to a position directly opposite to the flattening roller; and then the second adjusting screw is engaged and rotated to adjust the left and right of the second movable saddle, so that The flattening roller support seat is moved to a suitable position for disassembly and assembly of the flattening roller, and finally the flattening roller is accurately and quickly placed on the flattening roller support seat for disassembly and installation of auxiliary support, which effectively improves the disassembly and installation speed and accuracy of the flattening roller, thereby ensuring the overall rolling quality and efficiency of the aluminum foil rolling mill, and solves the problem that in the current process of replacing the flattening roller of the aluminum foil rolling mill, due to the lack of special and efficient disassembly and assembly tooling, the disassembly and assembly of the flattening roller is usually difficult, time-consuming and labor-intensive, and the installation accuracy is poor, which ultimately results in low overall rolling quality and production efficiency of the aluminum foil rolling mill.

[0014] The sliding and lifting of the lifting guide post in the guide post mounting plate in the utility model effectively ensures the stability of the device when the hydraulic lifting cylinder lifts the guide rod and the flattening roller support seat as a whole, thereby ensuring the accuracy and safety of the overall position adjustment of the first movable saddle and the second movable saddle, and ensuring the overall efficiency of the disassembly and assembly of the flattening roller.
