Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a composite forming device and method for sheet metal. Background technique [0002] Heterogeneous metal laminates are a new type of composite sheet material combined in a layered composite manner. Through the composite of multi-layer materials, the special physical and mechanical properties of various metals are fully utilized and rationally utilized, and they have ideal electrical and thermal properties. , low density, excellent bending stiffness, collapse resistance and vibration damping characteristics, the overall performance is superior to that of a single metal. [0003] Chinese patent CN 106311876A proposes a method of combining incremental forming and additive manufacturing to process thin-walled parts containing blocks, which shortens the manufacturing cycle of complex thin-walled parts. Chinese patent CN 107737929A proposes a method of combining incremental formi...

AI Technical Summary

Problems solved by technology

Chinese patent CN 107737929A proposes a method of combining incremental forming and 3D printing to process variable-wall thickness sheet metal parts, which solves the problem that the side wall becomes thinner and the thickness of the sheet metal cannot be controlled during incremental forming

However, the composite sheet produced by the above device has the disadvantages of poor surface quality, difficulty in controlling the temperature during welding, complicated friction stir process, high axial force and low bonding strength of laminated plates, etc.
