Abstract：

GQ280 cold-rolled high yield strength steel is a new kind of high strength steel used for car stamping parts，but it has low stamping performance and large bending springback. Obtained by tensile test, the tensile strength of GQ280 steel plate was 420 MPa and the yield ratio was 0.8. The forming process of GQ280 steel seat lock support plate was simulated by Dynaform. Therigidity, stress distribution and strength of parts are improved significantly by setting reinforcing ribonsupport plate. The springback is controlled effectively and dropped by 34.3%-84.47%.
