Title:
DIE DEVICE FOR FORMING ALUMINUM ALLOY CROSS MEMBER FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/143524
Kind Code:
A1
Abstract:
The present invention relates to a die device for forming an aluminum alloy cross member for a vehicle. That is, by an aluminum alloy (TL100C) material substituting for a conventional steel material as the metallic material used in a cross member for a vehicle, weight reduction and stability of a vehicle body can be achieved at the same time. Particularly, the purpose of the present invention is to provide a progressive press die device, which is for forming the aluminum alloy cross member and can prevent the occurrence of various defects, such as folds, scratches, a burning phenomenon, spring-back, burr, and a scrap-sticking phenomenon, by establishing a progressive forming process analysis technique for the aluminum alloy plate through a forming analysis taking into account the characteristics of an aluminum alloy plate forming method, predictions of shape and thickness distribution and stress distribution for each process, predictions of forming-defects (folds, scratches, a burning phenomenon, spring-back, and the like), and the like.
