Abstract

The invention provides an aluminum alloy battery box composite forming device, belongs to the field of metal material processing and forming, and solves the problem that an existing electric vehicle battery box forming process easily leads to poor quality of the formed part. The forming device lies in that a supporting plate, a preforming concave die and a pressing plate are stacked on a forming concave die sequentially from bottom to top; a first through cavity, a preforming through cavity, a second through cavity and a forming cavity form a vertically communicating cavity; a to-be-formed aluminum alloy sheet is clamped between the pressing plate and the preforming concave die; an electromagnetic pulse preforming unit is used for preforming the aluminum alloy sheet in the performing through cavity; an electroplastic element makes the preformed aluminum alloy sheet generate an electroplastic effect; a stamping forming unit is used for secondary forming of the aluminum alloy sheet withelectroplastic effect in the forming cavity; and an electromagnetic pulse rectifying unit is used for performing electromagnetic pulse forming on a fillet region of the reformed aluminum alloy sheet,so that the fillet region of the aluminum alloy sheet is further adhered to the fillet region of the forming cavity.

Description

technical field [0001] The invention relates to an aluminum alloy battery case forming device, which belongs to the field of metal material processing and forming. Background technique [0002] In recent years, with the continuous increase of car ownership, the problems of energy crisis and environmental pollution have become increasingly prominent. Under this background, with the dual support of the national new energy policy and the market, electric vehicles have developed rapidly . Compared with traditional fuel vehicles, electric vehicles have many advantages such as low emission, low noise, simple operation and convenient maintenance, and have incomparable advantages in environmental protection and energy saving. They are regarded as an effective way to solve human energy and environmental pressure. [0003] At present, the most important factor limiting the further development and popularization of electric vehicles is the low mileage of electric vehicles. Therefore,...
