Technical field

The utility model relates to a kind of punch-forming mold, more particularly a kind of diel that realizes die-cut scrap (bridge) and peripheral flanging synchronous forming in progressive die.

Background technology

Some stamping products in the market, the part of whole flange more particularly, mainly be by blanking with the single die tool, die-cut, operations such as flange are finished, more advanced operation also is by progressive die the operation outside the flange all to be finished, realize this procedure of flange by the single die tool again, can't be implemented in the progressive die die-cut scrap (bridge) and bending synchronous forming all around, therefore part of punching press needs several procedures to add together just to finish, make utilization rate of raw materials low, the accuracy of manufacture of part is low, the size instability, the scrappage height, production efficiency is very low, needs a large amount of personnel simultaneously, pressing equipment, half-finished Turnover Box, place or the like.

The utility model content

In order to overcome the problem that prior art exists, the purpose of this utility model is to provide the high die-cut scrap (bridge) of a kind of part accuracy of manufacture height, dimensionally stable, production efficiency and the diel of peripheral flanging synchronous forming.

For achieving the above object, the utility model solves the technical scheme that its technical problem adopts and is:

The diel of a kind of die-cut scrap (bridge) and peripheral flanging synchronous forming, comprise upper die and lower die, wherein patrix comprises upper bolster, upper padding plate, punch retainer, discharging backboard and stripper, counterdie comprises lower bolster, lower bolster and die shoe, cooperates and realizes guiding and fix by being arranged on the inner guiding post on the patrix and being arranged on interior guide pin bushing on the counterdie between patrix and the counterdie.

Described patrix (scrap (bridge) and last semi-finished product place) also is provided with die-cut punch and bending punch, die-cut punch is fixed on the punch retainer by the patrix screw, the bending punch is positioned at punch retainer, it is a movable part, be provided with spacing collar and screw in bending punch upper end, can control the movable stroke of bending punch, spacing collar is affiliated on upper padding plate, and in the upper bolster of spacing collar upper end, be provided with the patrix spring, the patrix spring withstands on the spacing collar, the upper end of patrix spring also is provided with set screw, can play the effect of the spring force of regulating the patrix spring;

Described counterdie is provided with bending die and die-cut die on lower bolster, the inboard of bending die is provided with the binder floating block, under off working state, the surface of bending die and binder floating block at grade, be provided with push rod and counterdie spring below the binder floating block, the flange of push rod is affiliated on lower bolster, and the counterdie spring withstands on the push rod, and the bottom of counterdie spring is provided with the counterdie set screw of the pressure-plate-force that is used for regulating the binder floating block;

The die-cut punch of patrix is corresponding with the die-cut die of counterdie, and the bending punch of patrix is corresponding with the bending die of counterdie.

Under off working state, the above-mentioned die-cut punch of the aspect ratio of bending punch in stripper exceeds a parameter K, and the K value is according to the bending of product height and the product material is thick sets.

Above-mentioned bending die and die-cut die are on same inserting.

Further,, be used for the part after the moulding kept away position and discharging effect, and the highly high 0.1mm of the bending of the depth ratio product of groove near being milled with a groove around the bending punch at the stripper back side.
