Progressive die capable of solving problem of burr extrusion during bending

The progressive die comprises an upper die assembly and a lower die assembly, the upper die assembly comprises an upper die base, an upper padding plate, an upper clamping plate, a back stripping plate and an upper stripping plate which are sequentially arranged from top to bottom, and the lower die assembly comprises a lower die plate, a lower padding plate and a lower die base which are sequentially and fixedly connected from top to bottom; a first bending female die, a second bending female die and a shaping block are sequentially arranged on the upper stripping plate in the moving direction of a material belt, a shaping platform and a shaping inclined face are arranged on the bottom face of the shaping block, and the shaping platform is located over the shaping inclined face. When the progressive die moves from top to bottom to be closed, the shaping platform can press burrs extruded by a bent edge of a workpiece, the burrs are flattened to the size not exceeding the size of a product, and the vertical st
