The invention discloses a
progressive stamping die for a round float valve. The die comprises an upper die body and a lower die body, wherein the upper die body comprises an upper die base, an upper base plate, an upper clamping plate, a stop plate and a stripper plate, the lower die comprises a lower die base, a lower base plate and a lower die plate, an air port
puncturing male die body, a primary
punching male die body, a trimming male die body, a secondary
punching male die body, a composite male die body, a valve leg
puncturing male die body, a valve leg forming male die body, an edge forming male die body, an upper valve leg forming male die body and a
cut-forming male die body are fixed on the upper clamping plate, and an air port
punching female die body, a primary punching female die body, a trimming female die body, a secondary punching female die body, a composite female die body, a valve leg
puncturing female die body, a valve leg forming female die body, an edge forming female die body, an upper valve leg forming female die body and a
cut-forming male die body are fixed on the lower die plate. The invention further discloses a round float valve
stamping technology. According to the technology, a
steel belt is conveyed into the
progressive stamping die for the round float valve in a step-by-step mode to conduct
progressive stamping. According to the progressive
stamping die for the round float valve and the
stamping technology, round float valve production efficiency is high and cost is low.
