The invention relates to the technical field of dies, and discloses a variable-
diameter special-shaped nut
continuous production die which comprises an upper die, an ejector plate, a female die plate, a material returning plate, a male die plate, a supporting plate and a base, the male die plate is installed on the base, a replacement
assembly is arranged at the top end of the supporting plate, a guide adjusting
assembly is arranged at the top end of the base, and the guide adjusting
assembly is connected with the upper die. A male die plate is arranged on the upper die, a stripper plate movably sleeves the male die plate, an ejector plate and a female die plate are sequentially mounted on the lower surface of the upper die, a
stamping assembly is mounted on the male die plate, and a sleeving hole corresponding to the
stamping assembly is formed in the upper surface of the stripper plate and used for being movably mounted on the male die plate. A pressed groove hole is formed in the position, corresponding to the
stamping assembly, of the female die plate. Fastening connection of the upper die body, the ejector plate and the female die plate is guaranteed through the short screws, the upper die body and the stripper plate are accurately aligned through the positioning pins, the upper die is connected with the base through the threaded nails, and the die can be rapidly and accurately installed in place.
