Description
Technical field
The present invention relates to forging shaving die technical field, more particularly to a kind of edge-cutting and hole-punching school being easy to quick die change
Positive compound die.
Background technology
Forging edge-cutting and hole-punching correcting combined die, is excision forging flash, gross weight after the completion of forging finish-forging, simultaneously to forging
A kind of special process equipment that part is corrected.Existing edge-cutting and hole-punching correcting combined die is usually that backing-out punch is built in connection
Inside the cavity that plate is formed with upper bolster, nitrogen spring is built in the cavity on backing-out punch top, so leads to changing product
When it is necessary to the backing-out punch that could change other products, troublesome poeration are all taken apart to whole mould bases, waste time and energy, and
Backing-out punch must be simultaneously achieved the effect carrying nitrogen spring and ejection forging, and structure is larger, makes difficult, and by outside forging
The restriction of shape, does not have versatility.The drift of existing edge-cutting and hole-punching correcting combined die typically has two kinds of connected modes：One is punching
It is provided with the passage that screw rod passes through in headstock, punch holder passage and drift upper end are passed through from upper bolster upper surface using long bolt
Screw-threaded counterbore, realizes threaded, and this mode is long due to screw rod, and its intensity is difficult to ensure that, and dismantles and need to consolidate during drift
Determine drift, from upper bolster upper surface dismantling screw, generally need two people's cooperations, troublesome poeration；Two is to arrange screw rod in drift lower end
The passage passing through, screw rod is connected through passage with the screw-threaded counterbore of punch holder lower end, and such drift dismounting is simple, but is affected by spiral shell
The restriction of bar turret head size, leads to this structure cannot realize aperture is less than with the punching in the hole of 50mm.If by backing-out punch
Split into the backing-out punch seat being built in connecting plate and the backing-out punch being placed on outside connecting plate, if drift carries screw rod simultaneously,
The replacing of so product avoids the need for mould bases is integrally split, and dismantle quite convenient, but when mould structure is complicated, such as
What design mould structure is insoluble problem.
Content of the invention
Present invention aims to the deficiencies in the prior art, and a kind of edge-cutting and hole-punching school being easy to quick die change is provided
