Secondly, compared the effects of different parameters of flange bending hydraulic rubber forming model on hydraulic rubber forming, and draw some conclusions of designing the side blank holder.

As for flange bending hydraulic rubber forming, the main defect is wrinkling of flange.

The utility model relates to a metal plate rubber pad forming mould device, particularly to a combined mould suitable for rubber pad forming with sharp angles and a plurality of bending edges.
