Description
Technical field
Auto panel technical field of mold is the utility model is related to, more particularly to a kind of die puncture for processing auto panel
Knife structure.
Background technology
Drawing operation is to ensure that covering makes one of qualified most important technique, and its effect is to pass through tabular blank
The plastic deformation of material turns into a kind of technique of three-dimensional shape.In the forming process of automobile panel, in order to avoid material is mended
The product product area Local Cracking phenomenon occurred not in time is filled, it is necessary to set puncture knife at the technique supplement position of covering
Structure, the corresponding technique supplement region on product is actively punctured in pre-determined distance before mould closes, material is mended by technique
Zone plate stream is filled to the position easily ftractureed, to avoid because product caused by feed deficiency ftractures.Existing puncture knife by
In puncturing, place's material flowing is uncontrollable, causes production stability poor, influences article surface quality, while processing and fabricating also be present
Difficulty, the shortcomings that inconvenient maintenance.
The content of the invention
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of die puncture knife structure for processing auto panel,
Processing and manufacturing difficulty can be reduced, ensures the quality of product, production stability is good, practical, is adapted to more complex parts
Drawing and moulding.
Realize that the technical solution of the utility model is as follows：
A kind of die puncture knife structure for processing auto panel, including upper die and lower die, the bottom of the upper mould are provided with peace
Tankage, puncture knife body is connected with mounting groove, and puncture knife body includes mounting blocks and the knife being arranged on mounting blocks bottom face
Sword, mounting blocks are arranged in mounting groove and are fixedly connected by fixture with upper mould, the bottom of the bottom face of mounting blocks and upper mould
Flush；Blade includes linear main cutting edge and is connected to the side edge mouth of main cutting edge both sides, and side edge mouth is semicircular structure,
The end of side edge mouth is connected with the contraction cutting edge that width diminishes；The upper surface of the lower mould is provided with the elasticity for being used for installing plate
Block, it is connected between elastomer block and lower mould by lower bolster, the lower bolster includes lower-left backing plate and bottom right backing plate, lower-left backing plate,
Extruding space is formed between bottom right backing plate, lower mould and elastomer block, the extruding space faces puncture knife body.
Above-mentioned scheme is employed, first, puncture knife body is arranged in mounting groove by fixture, the side of removing and installing
Just, be easy to repair and maintenance, various sizes of puncture knife can be changed, it is practical, be adapted to more complex parts drawing into
Type；When being punctured to sheet material, because the bottom of upper mould and the bottom face of mounting blocks flush, it is possible to be pressed in sheet material is smooth
On lower mould, and elastomer block is provided with lower mould, it has binder effect, and for sheet material in drawing process, sheet material is punctured region
Interior material flowing can keep in balance, and so as to ensure product stability, reduce processing and manufacturing difficulty, ensure the matter of product
Amount；When puncture knife punctures sheet material, due to extruding the presence in space, elastomer block is just naturally extended downwardly, can so prevented
Elastomer block ftractures, and plays a part of autoprotection, extends its service life；Puncture knife body also has processing and manufacturing simply, letter
Change mould structure, it is cost-effective, it is easy to maintenance the characteristics of.
Further, the section of the blade is V-structure.
Further, it is connected between the mounting blocks and upper mould by upper padding plate, is provided with mounting blocks and is used to install admittedly
Determine the connecting hole of part, the connecting hole is arranged on the inner side of blade.
Further, the elastomer block is the excellent power glue of polyurethane.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the structural representation of puncture knife body.
Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1 and Fig. 2, a kind of die puncture knife structure for processing auto panel, including upper mould 1 and lower mould 2, the upper mould
1 bottom is provided with mounting groove 3, and puncture knife body 4 is connected with mounting groove 3, and puncture knife body includes mounting blocks 41 and is arranged on
Blade 42 on mounting blocks bottom face, the section of blade is V-structure, and structural strength is high, and service life length, mounting blocks 41 are set
It is fixedly connected in mounting groove 3 and by bolt 5 with upper mould 1, the bottom face of mounting blocks 41 flushes with the bottom of upper mould 1；Blade
42 include linear main cutting edge with 43 and are connected to the side edge mouths 44 of main cutting edge both sides, and side edge mouth is semicircular structure, in side
The end of cutting edge is connected with the contraction cutting edge 45 that width diminishes；The upper surface of the lower mould 2, which is provided with, to be used to install plate 11
The excellent power glue elasticity block 6 of polyurethane, is connected between elastomer block and lower mould by lower bolster, and the lower bolster includes the He of lower-left backing plate 7
Bottom right backing plate 8, extruding space 9 is formed between lower-left backing plate, bottom right backing plate, lower mould and elastomer block, the extruding space faces thorn
Broken knife body.
It is connected between mounting blocks and upper mould by upper padding plate 10, ensures sound construction, prevent from loosening in use, have influence on production
The quality of product, is provided with the connecting hole 12 for mounting fixing parts on mounting blocks, and the connecting hole is arranged on the inner side of blade, is easy to
