Description
Technical field
The present invention relates to a kind of bounce-proof mould.
Background technology
All die punchings can have certain waste material, necessarily be worn and torn when that can exist after drift long-term work, and many small
Scrap can be sticked in punch tip, cause the drift time more long easier waste material for going out product to stick on drift to take to just
In the mould of production, burn failure is caused.In mould production process, typically occur that many waste materials do not drop to finger completely
The situation of fixed blanking regional location, can all be pushed down product completely using stripper plate under normal circumstances, and such as type face is excessive generally
Corresponding safeguard measure will not be set, fallen on so as to inevitably there is waste material on mould, and then influence production.
License notification number CN205147020U discloses a kind of automobile high-strength thick sheet piercing mould bounce-proof knot
Structure, it includes four convex beveled cones are distributed with upper strata cavity plate and lower floor's cavity plate, the mould intracavity wall of lower floor's cavity plate.Institute
State between upper strata cavity plate and lower floor's cavity plate by fixed above and below fastener.But because of the poor characteristic of high-strength panel ductility,
Waste material extension is small, and the mould is not applied to the material of poor ductility.
License notification number CN203409067U discloses a kind of blanking die with bounce-proof function, belongs to metal
