Device of the present invention is realized the plate progressive molding in such a way:
The first step: a series of screens are lined up two row place on the U-shaped base, and the arc section of two row screens is relative.
Second step: slide block is placed the screen outside, and connect U-shaped base, slide block and screen with guide pillar.
The 3rd step: along the position of adjusting screen, make screen be arranged in the shape of part outline according to the outline of part to be processed, then moving slider compresses screen, by bolt screen and slide block is fixed on the U-shaped base.
The 4th step: plate is placed on the plane of slide block, screen and U-shaped base composition, and pressing plate is placed the plate upper surface, by bolt pressing plate and plate are separately fixed on U-shaped base right side and the slide block.
The 5th step: the shape according to plate arranges suitable movement of tool track, carries out progressive molding processing.
Compared with prior art, the invention has the advantages that with the traditional non-yielding prop backing plate of the adjustable screen replacement in a series of positions.Different according to part to be processed, the position that changes screen forms suitable part outer contour shape, play the effect of bearing plate in negative progressive molding process, not needing has increased the flexibility of negative progressive molding workbench for different parts provides different bearing plates.
