Description

Technical Field

[0001] The invention relates to the technical field of composite metal sheet processing, in particular to a flanging device for composite metal sheet processing. Background Art

[0002] Since composite metal sheets are made of different metal layers, they have high strength and rigidity and can withstand large loads and moments. This feature makes composite metal sheets perform well in situations that require high-strength support and load-bearing, such as aerospace, automobile manufacturing and other fields. The shape of the edge of the composite metal sheet can be changed by flanging treatment to form a curling effect, thereby enhancing the local strength and rigidity of the edge, which is especially important for parts that need to withstand external impact and friction.

[0003] In the final stage of the flanging operation on the composite metal sheet, due to the small radius of the flanging, the flanging of the composite metal sheet is easily damaged, affecting the flanging effect of the composite metal sheet; at the same time, after the composite metal sheet is flanging, it is necessary to continuously heat it to prevent the composite metal sheet from resetting, making it inconvenient to quickly cut the composite metal sheet after flanging, affecting the efficiency of subsequent flanging of the composite metal sheet.
