For the problems of low production efficiency and product qualification rate for bracket connecting strip parts, its structure was analyzed, and a set of progressive die was designed. Then, two sets of <bending+coiling> process dies were designed,aiming at two different <bending+coiling> structural features, such as upward and downward. In order to overcome the spingback phenomenon and the bending angle of 90°, two processes of pre-bending and bending were set up. In order to ensure the shape of coil, three processes, namely, pre-coiling ①, pre-coiling ② and coiling, were set up. In order to ensure that the process parts were smoothly demolded after bending, the die was designed as a slider structure, and the demolding was achieved by the lateral movement of slider. Ultimately, the products produced using this progressive die have stable quality and realize the mass production
