8. The non-standard wedge device for automotive stamping dies according to claim 7, characterized in that, The device also includes a first electric telescopic rod (19) that drives the transverse pressure plate (15) to move horizontally and a second electric telescopic rod (20) that drives the longitudinal pressure plate (16) to move horizontally vertically; wherein, The upper part of the base (1) located between the bottom mold (2) and the wedge (4) is recessed inward to form an assembly groove, and a first electric telescopic rod (19) is horizontally fixed in the assembly groove. The bottom part of the transverse pressure plate (15) extends into the assembly groove and is fixed on the telescopic end of the first electric telescopic rod (19). A second electric telescopic rod (20) is vertically fixed at the upper end of the base (1) located next to the bottom mold (2). A lifting plate (21) is horizontally fixed at the telescopic end of the second electric telescopic rod (20). The longitudinal pressure plate (16) is horizontally fixed on the lifting plate (21).

9. The non-standard wedge device for automotive stamping dies according to claim 1, characterized in that, The device also includes a third electric telescopic rod (23) for driving the wedge-shaped drive member (5) to move up and down in the vertical direction; wherein, A support base (22) is vertically fixed at the upper end of the base (1) located next to the wedge (4). A third electric telescopic rod (23) is vertically fixed through the top of the support base (22). The telescopic end of the third electric telescopic rod (23) is fixed on the wedge-shaped drive (5). A guide rod (24) is vertically fixed on the wedge-shaped drive (5) located next to the third electric telescopic rod (23).
