| description | The invention relates to a centrifugal fan three-dimensional flow blade multi-point forming die. The technical problems that an existing multi-point forming die is integrated in a press machine and connected with a shape adjusting mechanism, the die and the press machine need to be purchased in a complete set, cost is high, maintenance is difficult, faults are prone to occurring, and precision is low are solved. The die comprises an upper die assembly, a lower die assembly, a height limiting assembly and a base plate assembly. The size and the structure of the lower die assembly are the same as those of the upper die assembly, and each of the lower die assembly and the upper die assembly comprises a cover plate, a punch base and a punch array arranged in the punch base; the tails of punches in the punch array penetrate through the punch base to be inserted into the cover plate, and the height positions of the punches can be adjusted. The punch heads of the upper die assembly and the lower die assembly are opp |
