Abstract
The utility model relates to a kind of mould, is specially minim gap blanking die, comprises upper die and lower die; Patrix comprises punch retainer, punch and stripper; Punch retainer is fixed on below punch seat board, and punch is by briquetting and punch retainer matched in clearance; Have through hole in stripper, punch is through the through hole of stripper; Chamfering is provided with outside the edge of a knife of punch top; Counterdie comprises die, and die is fixed in die block, and die block is fixed on die seat board by die backing plate.The utility model provides minim gap blanking die, and blanking process convex mould top edge of a knife chamfering is first advanced into die, location punch cutting edge; Then punch cutting edge enters die, carries out minim gap stamping-out.What the cumulative limit so namely solving two-plate structure caused gnaws cutter phenomenon, and the cumulative limit also solved because of three-plate type structure causes die cavity to coordinate to become the phenomenon causing greatly gnawing cutter with locating to wear and tear in production, and reduces the machining accuracy of mould.
Description
Technical field
The utility model relates to a kind of mould, is specially minim gap blanking die.
Background technology
In the design process of mould, often can run into some very thin materials, such as the material of environment-friendly battery pole piece, thickness is only the Copper Foil of 0.01mm; In the gap that the shaping middle needs of the Dies ' Blanking of this type of thin material are minimum, gap is 0.002mm even in theory, could realize the minimized effect of gouged spews.Precision die blanking structure is difficult to realize this type of required precision.Traditional moulds does precision with punch retainer, and punch position, location, easily produces during minim gap stamping-out and gnaw edge of a knife phenomenon.Typical case's three-plate type blanking structure, does precision with stripper, punch position, location, still easily produces and gnaw the edge of a knife phenomenon during minim gap stamping-out.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of for punching press minim gap blanking die, ensures that stamping products high accuracy and gouged spews minimize.
Concrete technical scheme is:
Minim gap blanking die, comprises upper die and lower die; Patrix comprises punch retainer, punch and stripper; Punch retainer is fixed on below punch seat board, and punch is by briquetting and punch retainer matched in clearance; Have through hole in stripper, punch is through the through hole of stripper; Chamfering is provided with outside the edge of a knife of punch top; Counterdie comprises die, and die is fixed in die block, and die block is fixed on die seat board by die backing plate.
The utility model provides minim gap blanking die, and blanking process convex mould top edge of a knife chamfering is first advanced into die, location punch cutting edge; Then punch cutting edge enters die, carries out minim gap stamping-out.What the cumulative limit so namely solving two-plate structure caused gnaws cutter phenomenon, and the cumulative limit also solved because of three-plate type structure causes die cavity to coordinate to become the phenomenon causing greatly gnawing cutter with locating to wear and tear in production, and reduces the machining accuracy of mould.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial enlargement structural representation of the present utility model.
Detailed description of the invention
By reference to the accompanying drawings, specific embodiment of the utility model is described.
As depicted in figs. 1 and 2, minim gap blanking die, comprises upper die and lower die; Patrix comprises punch retainer 2, punch 9 and stripper 3; Punch retainer 2 is fixed on below punch seat board 1, and punch 9 is by briquetting 10 and punch retainer 2 matched in clearance; Have through hole in stripper 3, punch 9 is through the through hole of stripper 3; Chamfering 91 is provided with outside the edge of a knife of punch 9 top; Counterdie comprises die 7, and die 7 is fixed in die block 4, and die block 4 is fixed on die seat board 6 by die backing plate 5.
Punch retainer 2 die cavity and punch 9 gap are monolateral 0.01mm, and stripper 3 through hole and punch 9 gap are monolateral 0.05mm, and stripper 3 is for binder, and without positioning and guiding effect, punch 9 imports die 7 voluntarily, realizes minim gap stamping-out.Mold movement process: stripper 3 lower surface is higher than punch 9 lower surface when top dead-centre state; Mould is descending, and stripper 3 first pushes down material 8, and punch 9 head chamfering 91 guiding enters die 7, and now punch 9 is accurately located, and continue the accurate cutting material 8 of descending punch 9 and be pushed into bottom dead centre, waste material falls; Punch 9 is up exits die 7, and continue up punch 9 and be retracted into stripper 3, whole patrix goes upward to top dead-centre state, and blanking movement completes.
