[0004] In view of the above problems in the prior art, the utility model provides a stamping die for a shielding component, which solves the problem that the prior stamping die for the shielding component cannot perform inclined stamping on a plurality of discrete L-shaped plates on a horizontal plane.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A stamping die for a shielding component is provided, comprising an upper die base and a lower die base, wherein a first stamping die group, a bending die group, a second stamping die group, a shaping die group, a tilting stamping die group and a stripping die group are sequentially arranged between the upper die base and the lower die base from left to right; the first stamping die group is used for stamping a blank out of a material strip, the blank comprising a rectangular plate, a plurality of convex plates are arranged on one side of the rectangular plate, the bending die group is used for bending the plurality of convex plates into L-shaped plates, and the plurality of L-shaped plates are perpendicular to the rectangular plate, the second stamping die group is used for cutting off two side edges of the rectangular plate; the shaping die group is used for extruding the rectangular plate into a ring plate; the tilting stamping die group is used for extruding the vertical surface of the L-shaped plate located on a circle of the ring plate into an inclined surface; the stripping die group is used for separating the ring plate from the material strip.
