Abstract

The invention discloses a forming die for an assembled wedge of an acute-angle U-shaped stamping part, belongs to the technical field of forming of cold stamping dies, and can be used for stamping an acute-angle U-shaped part and solving the problem of forming resilience of the U-shaped part. The male die and the male die guide seat move relatively, the male die moves downwards, the plate is firstly bent into a U shape with the angle larger than 90 degrees, the male die continues to move downwards, and the wedge pushes the sliding female die to move horizontally by utilizing the wedge surface, so that acute angle forming is realized. The wedge goes upward, the male die moves and lags under the action of the rubber elasticity, and when the sliding female die is brought back by the spring and the inclined part of the sliding female die is kept away, the limiting block drives the male die to return, so that one-step forming is completed. The insert of the punch and the die at different angles is replaced, so that the multi-angle acute angle forming can be realized, and the manufacturing period and the cost of the die are reduced.
