A continuous stamping die for machining a lens frame

Abstract

The utility model relates to continuous punch press die technical field especially relates to a kind of for processing lens frame's continuous punch press die, including upper die module and lower die module, upper die module is provided with cutting mechanism, cutting mechanism includes the cutting slot of longitudinal coaxial forming in punch, material pressing plate and upper die driving seat, longitudinal cutting slot is slidably installed with longitudinal cutting knife, longitudinal cutting slot top is provided with the cutting knife driving block of horizontal movement, in cutting process, guide slot not only limit the deviation of cutting knife, also realize accurate positioning by with the pre-contact of workpiece;When driving block moves horizontally, can synchronously trigger longitudinal cutting knife and carry out 2 times or 3 times cutting action, directly cutting off and positioning the metal sheet of stamping forming according to preset quantity, such as two-by-two combination, three-by-three combination etc.This mechanism will originally need two processes, i.e. stamping+separate cutting process is integrated as once completion, extra equipment investment and artificial transfer link are saved, and production cost is significantly reduced.
