Described complete flanging die end is provided with the angle of falling R.
The protuberance longitudinal section of described complete flanging die is rectangular configuration, the shrinkage pool of described complete flange die Longitudinal section is rectangle mechanism.
The pre-flange body of described upper mold includes that rollover edge die, the pre-flange body of described lower mold include that pre-flange is convex Mould, during flange, described pre-flanging die inserts in rollover edge die and completes pre-flange action.
The protuberance longitudinal section of described pre-flanging die is isosceles trapezoid, and the shrinkage pool of described rollover edge die is vertical to be cut Face is isosceles trapezoid.
Described holding pad is arranged at the middle and lower part of upper mold edge iron and is connected with upper mold edge iron.
Described drift is arranged at the middle part of holding pad.
Compared with prior art, the invention have the advantages that
(1) service life is long: all deburrings all use insert form.Extend the service life of mould self, Reduce the infringement to the equipment of production and consume.
(2) easy to maintenance: use insert structure, maintenance time need not again by whole mold hoisting to maintenance sites, Take substantial amounts of place, only the insert needed repairing need to be pulled down and can be keeped in repair;
(3) ram efficiency is high, cost of stamping is low: produces continuously according to grading mode, decreases required jig frequency, Puncture motion and deburring action are carried out simultaneously, one-shot forming, and this mould is automatically to produce, and eliminates operator's Potential safety hazard.
(4) process modification of mould, traditional processing technology is to select drawing to produce, now by skill upgrading, Data analysis, structure improve after now we use full working procedure level progressive die to produce, directly use coiled strip feeding pass through punching, Deburring, shaping, flange, separation produce, drawing change into shaping production, and stock utilization improves.
