Description
Technical field
The present invention relates to piercing knife technical field of structures, specially a kind of paper perforating mould piercing knife.
Background technology
Diel, is that in Cold Press Working, material (metal is nonmetallic) is processed into part (or semi-finished product)
A kind of special process equipment, referred to as cold punching die (being commonly called as cold-punching mould), punching press are at room temperature using on forcing press
Mould pressure is applied to material, it is produced separation or is plastically deformed, so that a kind of pressure processing side of part needed for obtaining
Method, manufacture diel material have steel, hard alloy, steel bonded carbide, zinc-containing alloy, low-melting alloy, aluminium bronze,
High polymer material etc., the existing paper hole class formation processing of in the market, now needs first analysis product structure, listing needs processing department
Position, regioselective and empty avoiding position, select the punch press of Reasonable Parameters, are designed diel, punching die is that one kind is used for
The diel being punched out to workpiece, existing diel, including upper module and lower module, wherein upper module includes upper mould
Seat and punching cutter, die shoe include die shoe and cavity plate, and the descending drive punching cutter punching press of upper bolster is placed on recessed during work
Workpiece on mould upper surface, so as to complete punching press.
But piercing knife structure in the market is not only complicated, and function is single, is not provided with pressing plate, no
Processing one elastic force of workpiece can be given by pressing plate, make cutter Rapid reset, it is impossible to sonic propagation of being made an uproar when reducing punching, meanwhile,
The Some paper sheets punching die of in the market does not have paper scrap cleaning mechanism, and cutter interior is easily stuck in punching paper scrap waste material, influence
Punching quality and efficiency, and Some paper sheets perforating die has paper scrap cleaning mechanism, but need external dust catcher and air blower etc.
Device, more consumes energy and floor space is larger；Simultaneously existing cutter do not possess change cutter head feature, if tool wear, it is necessary to
More fall whole cutter, cause the wasting of resources.
The content of the invention
The present invention provides a kind of paper perforating mould piercing knife, and can effectively solve to propose in above-mentioned background technology asks
Topic.
