Description

Automatic shearing device for aluminum alloy strips Technical Field The invention relates to the technical field of aluminum alloy strip production, in particular to an automatic aluminum alloy strip shearing device. Background The aluminum alloy strip production is a modern manufacturing process with intensive technology and strict working procedures, and is widely applied to the fields of aerospace, new energy automobiles, electronic communication, packaging materials and the like. The production process begins with smelting and casting. After melting the high-purity aluminum ingot, adding alloy elements such as magnesium, silicon and the like for component blending, removing impurities through online degassing and filtering, and forming a plate blank by adopting an advanced continuous casting and rolling or semi-continuous casting process. And then, the blank enters a pretreatment stage, and component segregation is eliminated through homogenizing annealing, so that the processing plasticity is improved. The core process is rolling processing. The hot rolling process includes repeated rolling to certain thickness and crushing cast structure at high temperature, and the precise rolling process includes further thinning the thickness of the strip to micron level and automatic thickness control system to ensure that the dimensional tolerance reaches strict standard. The rolled strip is subjected to intermediate annealing or finished product annealing to regulate and control the mechanical properties and grain structure of the material. In the shearing processing process of the aluminum alloy strip, if the strip is not subjected to effective flattening treatment, the yield and the subsequent processing efficiency are directly affected. In the absence of flattening constraints, the strip is very prone to local buckling or flanging under the action of shear forces. Because stress release exists at the moment of shearing, the edge part of the strip which is not flattened can generate obvious burrs, wavy edges and even lotus edges, and the flatness of the end face is seriously affected. For high precision required electronic or automotive tapes, such edge defects may lead to out-of-tolerance gaps in subsequent welding or assembly.
