The invention relates to a discharging and punching integral die for a steam plate of a stainless steel steamer. The discharging and punching integral die comprises an upper die and a lower die. The upper die is provided with a punching handle, the lower die is provided with steam plate convex ribs, a circle of discharging cutting edge is arranged on the periphery of the outermost circle of the steam plate convex ribs, the center of the steam plate convex ribs is provided with a central hole punching concave platform, and the central hole punching concave platform can move up and down along acentral axis along with punching. The upper die is provided with a steam plate press die matched with the steam plate convex ribs, the center of the steam plate press die is provided with a central hole punch, the central hole punch is matched with the central hole punching concave platform to punch the central hole, and after the central hole is punched completely, the central hole punching concave platform pushes waste materials out. The discharging and integral die for a steam plate of a stainless steel steamer is simple in structure, efficient in processing and safe and convenient, has very good application and popularization values, and is mainly applied to mechanical processing of the steam plate of the stainless steel steamer.
