Description

Technical Field

[0001] The utility model relates to the technical field of application of aluminum foil rolling mill equipment, in particular to a disassembly and assembly device for a cone head of an aluminum foil rolling mill. Background Art

[0002] The aluminum foil rolling mill cone head is used in the process of unwinding and winding the rolling mill, and is arranged inside the rolling mill arch. The aluminum foil sleeve is tightened under the action of the hydraulic cylinder, and rotated under the drive of the motor, so that the aluminum foil is wound from the unwinding sleeve to the winding sleeve. Due to the use of the DC variable frequency motor, the tension of unwinding and winding is different, which can prevent the aluminum foil from loosening when winding at the winding position. The problem makes the cone head very important for the production of aluminum foil. However, due to long-term use, the cone head will inevitably wear out, causing the operating side and the driving side to be out of center after the sleeve is tightened, causing the sleeve to jump too much, seriously affecting the shape control of the aluminum foil, resulting in poor product shape and uncontrollable quality of the finished product. Therefore, the cone head needs to be maintained and replaced in time, but due to the obstruction of the rolling mill arch, the crane usually cannot directly lift the cone head. The operation of replacing the mill cone head each time is complicated, time-consuming and labor-intensive. At the same time, the operation safety risk is relatively large, which greatly affects the overall production efficiency of the aluminum foil rolling mill. Utility Model Content

[0011] The utility model provides a disassembly and assembly device for the cone head of an aluminum foil rolling mill, which is mainly composed of a trolley, a supporting arm, a lifting base, a hydraulic cylinder, a pulling grip and a hook. The device is moved as a whole to the front side of the cone head to be disassembled and assembled, and the lifting base is controlled by the hydraulic cylinder to drive the pulling grip to the position directly opposite the cone head. The supporting arm is safely supported by the supporting hydraulic cylinder, so that the pulling grip is accurately clamped at the rear end of the cone head. The pushing hydraulic cylinder is extended to tighten the hydraulic jack that is close to the fixed shaft of the cone head. In the process of the trolley driving the pulling grip to move in the reverse direction, The cone head can be disassembled accurately and quickly, and conversely, the cone head can be installed through the tightening action of the push hydraulic cylinder, which effectively improves the disassembly and assembly rate and operation safety of the cone head, thereby improving the overall production quality and efficiency of the aluminum foil rolling mill.

[0012] The pulling grip in the utility model is symmetrically installed at the top and bottom, which effectively ensures the stability of the pulling grip clamping the cone head, thereby ensuring the efficiency and safety of the cone head disassembly and assembly.

[0013] The arrangement of the supporting hydraulic cylinder and the supporting wheels in the utility model effectively ensures the stability of the entire supporting arm during the process of the trolley moving to drive the pulling, grabbing and disassembling of the cone head, thereby improving the overall operation safety of the cone head disassembly and assembly.
