Progressive stamping die for round float valve and stamping technology

Abstract

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.

Description

Technical field [0001] The invention relates to a circular float valve used for mass transfer equipment in the petrochemical field, in particular to a continuous stamping die and stamping process for the circular float valve. Background technique [0002] The float valve is a gas-phase dispersion component on the float valve tray, which can float on the tray and change its opening degree with the change of gas flow. There are many types of float valves, including round float valves and strip angle valves. At present, the round float valve is more commonly used. The existing round float valve is processed by a single-process, multi-step method and process, which has the following drawbacks and problems: [0003] 1. A lot of input equipment: because each punching machine with the corresponding mold can only process one process, for the round float valve, six processes are needed, so the corresponding equipment also needs six; [0004] 2. Large occupied area: more equipment will inev...
