Description
Technical field
This utility model relates to Stamping Die Technology field, especially relates to a kind of deburring waste material punching
Cut out mould.
Background technology
Mould design and manufacture technology is the core technology of modern punching production, along with modern manufacturing industry
Fast development, relevant enterprise such as automobile industry, electrical appliance industry pursue produce efficiently, safety can
While leaning on, the requirement to spare and accessory parts quality improves the most day by day, especially the quality of covering,
More and more higher including appearance requirement.Having more large-scale covering in automobile industry, it is with one
As stamping parts compare, there is material thin, complex-shaped, space curved surface is many, physical dimension is big,
Surface quality requirements high.The waste material overall dimensions of covering is big, and deburring shape is more complicated,
Need to use waste knife cut-out heel row waste material just convenient and safety.
Now widely used fixed scrap cutter is the composition surface utilizing deburring die plate insert
As a waste knife cutting edge, outside deburring punch, fill waste knife accordingly give up as another
Material edge, the waste knife of this structure the most simply solves the cut-out closing waste material, and
The discharge of waste material and the taking-up of product.There is following defect in its structure: owing to fixed waste material is cut
Breaking, edge-trimming cutter blade shape has height to rise and fall, and during trimming, the incision of cutting edge is asynchronous；Waste material
Elder generation's contact material cutting off, trimming after trimming edge at amputation knife, so inevitable in cut-off part week
Enclose, the deburring cross section quality of workpiece is affected, stamped workpieces usually can be made right
The effective profile of product should be made to produce the defect such as angle, burr of collapsing, sternly in scrap cutter position
Ghost image rings the surface quality of workpiece.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide one
Deburring waste material blanking die, on it, scrap cutter floats and arranges, and treats that periphery effective profile cutting edge is repaiied
While cut off waste material after completing again, the deburring cross section quality of workpiece will not be impacted.
In order to solve above-mentioned technical problem, the technical scheme that this utility model is used is:
This deburring waste material blanking die, including upper bolster and die shoe, described upper bolster is provided with
Trimming upper die and upper scrap cutter, described die shoe is provided with deburring lower mold and lower scrap cutter,
Also include that rocker piece, described upper scrap cutter are located on upper bolster by rocker piece.
The side of described upper scrap cutter coordinates with the side clearance of adjacent trimming upper die.
Described trimming upper die is deburring die plate insert, and deburring lower mold is deburring punch.
Described rocker piece is polyurethane block.
Described upper bolster bottom is provided with groove, and rocker piece is located in groove, and rocker piece lower end is connected with
Can slide up and down floating mounting-holder along groove, upper scrap cutter is fixed on floating mounting-holder.
Described rocker piece is elastic floating block, and the elastic force of rocker piece is cut more than scrap cutter position
Disconnected power.
Described upper bolster is provided with for floating mounting-holder moves downward spacing limited support
Plate.
This utility model compared with prior art, has the advantage that
The upper scrap cutter of this deburring waste material blanking die is arranged on floating mounting-holder, in deburring
When cutting knife cutting edge just comes into contact with, by the cushioning effect of rocker piece make upper scrap cutter cutting edge with
Adjacent trimming cutter cutting edge is highly consistent, after completing product deburring stamping-out, upper scrap cutter with
Rocker piece floats, and completes the cut-out action of waste material after touching lower scrap cutter；Owing to being etc. to repair
Waste material is cut off after cutting off waste material by limit cutting knife again, thus completely eliminates product at blanking process
In in the defect such as angle and burr of collapsing produced by waste knife correspondence position, it is ensured that product quality；
Reduce percent defective, save cost.

Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, it is embodied as of the present utility model
Mode is described in further detail.
As depicted in figs. 1 and 2, this deburring waste material blanking die, including upper bolster 1 and lower mold
Seat, upper bolster 1 is provided with trimming upper die and upper scrap cutter 4, and die shoe is provided with under deburring
Mould and lower scrap cutter 5, wherein, trimming upper die is deburring die plate insert, and deburring lower mold is for repairing
Limit punch, the setting corresponding with deburring punch of deburring die plate insert.
Upper scrap cutter 4 is located on upper bolster 1 by rocker piece 2, and its rocker piece is elastomer block,
Preferably rocker piece is polyurethane block.On in blanking process, scrap cutter first upwards floats, treat by
The function of waste material is cut off in periphery effective profile cutting edge deburring again after completing, solve existing fixed
Waste knife easily corresponding to scrap cutter position, makes the effective profile of product produce the angle hair that collapses
The defects such as thorn.
Upper bolster 1 bottom is provided with groove, and rocker piece 2 is located in groove, and rocker piece 2 lower end is even
Having and can slide up and down floating mounting-holder 3 along groove, upper scrap cutter is fixed on floating mounting-holder,
Die holder is provided with for floating mounting-holder moves downward spacing limit support board.Upper waste material is cut
The side of cutter coordinates with the side clearance of adjacent trimming upper die.
Wherein, upper and lower scrap cutter is at least provided with a pair；Rocker piece 2 is elastic floating block,
The elastic force of rocker piece is more than the cut-out power at scrap cutter position.
Utilize deburring waste material blanking die that plate carries out deburring waste material technique as follows:
When punching press starts, rocker piece, floating mounting-holder and upper scrap cutter are with under upper bolster
OK, trimming upper die contacts with deburring lower mold, now goes up scrap cutter by product reaction force acts
Compression rocker piece；
Along with continuing traveling downwardly of upper bolster, trimming upper die and trimming upper die are by the completeest for workpiece periphery
Becoming stamping-out deburring, meanwhile under the promotion of rocker piece, the upper scrap cutter of this floating continues
With the descending about 5mm of upper bolster, after completing stamping-out deburring, upper scrap cutter comes into contact with lower useless
Material cutting knife, upper and lower scrap cutter edge contacts also completes waste material cut-out；
Then, upper scrap cutter starts upwards to move upward with upper bolster and rocker piece, completes to repair
Leftover bits and pieces of material.
The most both completed while having ensure that deburring die and punch cutting edge action, completed again useless
The cut-out of material.Eliminate fixed upper waste knife to cause with periphery cutting edge repair because there is difference in height
Crack approach is in the defect such as angle and burr of collapsing in thickness of workpiece direction.
Above in conjunction with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model
Implement and be not subject to the restrictions described above, as long as have employed design of the present utility model and skill
The improvement of the various unsubstantialities that art scheme is carried out, or the most improved by design of the present utility model
Directly apply to other occasion with technical scheme, all protection domain of the present utility model it
In.
