11 junction of die fixed seat is supported with elastic element.
The cross-sectional shape of the cylindricality punch-pin 4 and cylindricality cavity plate 10 include round, rectangular or rectangle, with punch-pin 4 and
The cross-sectional shape of the corresponding annular punch-pin of cavity plate 10 and annular cavity plate includes circular ring shape, side's annular or rectangular annular.
The annular punch-pin and annular cavity plate consistency from top to bottom or interlaced；The quantity of the annular punch-pin and annular cavity plate
It is identical or different.
The elastic element includes polyurethane, helical spring, nitrogen cylinder component or hydraulic cylinder.
Strip width can be carried out using the mold and length is much larger than the workpiece sectional forming of die size, realized small
The big drip molding of die forming.
According to the mold structure characteristics, from outside to inside, gradually shaped sheet, utilizes elastic element transmitting to punch assemblies
Pressure, so that outside punch assemblies are pressed against the subsequent continuous compression plate of plate, and then make subsequent punch assemblies tighten plate when depressing,
Plate inflow velocity and direction are controlled, inhibits plate corrugation, improves forming quality and precision.
The technical effect of the utility model：
Plate stamping is carried out with annular anti-wrinkling mould using the metallic plate punching forming of the utility model, utilizes punch assemblies
The generation of ripple and gauffer on drip molding can be effectively suppressed in the compression plate effect of generation, realizes and shapes without wrinkle, obtains higher
Forming quality, the spherical part of more deep camber can also be obtained.
