Inclined wedge stamping mechanism, stamping die and stamping method for vehicle door hinge reinforcing plate

The invention discloses an inclined wedge stamping mechanism. The inclined wedge stamping mechanism comprises an inclined wedge sliding block and upper pressing plates slidably installed on the two sides of the inclined wedge sliding block. One side of the inclined wedge sliding block is matched with a lower driving base so that the vertical movement of the inclined wedge sliding block can be converted into horizontal movement. A trimming knife block is fixed to the other side of the inclined wedge sliding block. A V-shaped protrusion is vertically arranged in the middle of an installation surface, located on the same side of the trimming knife block, of the inclined wedge sliding block. The inclined wedge stamping mechanism further comprises a lower sliding block. A punching assembly is installed on the back portion of the lower sliding block. The two sides of the lower sliding block are each slidably connected with a lower pressing plate which is placed horizontally. The top surface of the lower sliding block is arranged obliquely, and a V-shaped groove matched with the V-shaped protrusion is vertically formed in the top surface of the lower sliding block. The V-shaped protrusion of the inclined wedge sliding block presses the V-shaped groove of the lower sliding block, so that the lower sliding block moves horizontally along the lower pressing plates. According to the scheme, the lower sliding block is arranged on the lower side of the inclined wedge stamping mechanism, the lower sliding block is driven to move in the horizontal direction while the inclined wedge sliding block conducts inclined wedge movement, and accordingly stamping at different angles can be completed at the same time.
