Abstract：

For the problem of springback easily produced when the bracket parts were pressed on the progressive die which affected the accuracy of parts, the trend and extent of springback change were analyzed by the empirical data, and the effective measures of reducing springback in horizontal stamping with wedge drive mechanism were pertinently put forward. Because of the feature that the wedge drive mechanism could press in any direction except stamping direction, three wedge drive mechanisms were set up at three work stations by the reasonable layout design. Then, the wedge angle of wedge drive mechanism were determined to be 45 ° by the analysis of the slider moving distance in the horizontal direction and based on the query of the diagram of wedge angle and wedge slide angle. Through the analysis of the working principle of the whole die, it shows that bending and shaping the bracket with wedge drive mechanism ensure the forming accuracy of bracket parts and improve its stamping efficiency.
