Description

Shear type cutting device for aluminum strip coil production Technical Field The invention relates to the technical field of aluminum strip coil production, in particular to a shear type cutting device for aluminum strip coil production. Background The production of aluminum strip coil is a key link in the modern aluminum processing industry, and covers core procedures such as casting, hot rolling, cold rolling, finishing, heat treatment and the like, and the product is widely applied to the fields of transportation, architectural decoration, electronic appliances, packaging materials and the like. The production starts from the smelting process, after the electrolytic aluminum liquid or the aluminum ingot for remelting is melted at high temperature, alloying elements are added for fine adjustment of components, and hydrogen and impurities are removed through degassing and filtering, so that the purity of the melt is ensured. After being manufactured into a slab ingot by semi-continuous casting, the slab ingot enters a hot rolling process, the thickness of the slab ingot is thinned to 2-8 mm by rough rolling and finish rolling, and meanwhile, the defect of casting structure is eliminated. And then cold rolling is carried out, precise thickness control and surface quality optimization are realized in multi-pass rolling, and the thickness of a finished product can be reduced to below 0.2 millimeter. In the rolling process, the intermediate annealing is matched to eliminate work hardening and restore the plasticity of the material. The aluminum strip coiled material has edge tilting in the edge trimming process, and a series of linkage effects can be caused on the subsequent production flow and the quality of finished products. By edge-turned is meant that the strip edge after shearing does not remain flat, but rather assumes an upward or downward curled state, which geometrical defect first interferes with the stability of the coiling process. When the edge-warped part enters the coiling machine, the edge part of the coiled material is uneven to form a tower-shaped coil or telescope-shaped coiling, thereby not only affecting the appearance of the coiled material, but also causing interlayer scratch and local stress concentration in the annealing or transferring process of the coil Disclosure of Invention The shearing and cutting device for aluminum strip coil production comprises a bottom plate, wherein a case is fixedly arranged on the upper surface of the bottom plate; the driving mechanism is used for driving the aluminum strip coil to generate self-rotation and is fixedly arranged at the inner cavity of the case; The positioning mechanism is fixedly arranged on the upper surface of the case; the trimming mechanism is used for correcting the uneven outer edge of the aluminum strip coil, and is arranged at the top of the positioning mechanism; the driving mechanism comprises a limit ring, the limit ring penetrates through the upper surface of the chassis, a rolling bearing is fixedly arranged at the inner wall of the limit ring, a rotating cylinder is fixedly arranged at the inner ring of the rolling bearing, and a placing ring is fixedly arranged on the outer surface of the rotating cylinder.
