Abstract
The utility model discloses a kind of diel, belong to punch forming device field.Provide a kind of diel that waste material is jumped out when preventing punch forming.Diel, comprises punch, die, as stamping material thickness >=0.8mm, described die mould knife-edge part is provided with bulge-structure; As stamping material thickness≤0.8mm, described die mould knife-edge part is provided with sunk structure.
Description
Technical field
The utility model relates to punch forming device field, especially diel.
Background technology
Stamping forming mould comprises punch and die, can process the shape of required product.Die is profile for sweeping away product or the middle waste material falling product.Mould can produce waste material when punch forming is produced, and waste material is as easy as rolling off a log to be jumped out, and causes the situation weighing wounded product, damage, particularly for looking products.Increase the rework rate of product, scrappage, reduce production efficiency, improve production cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of diel that waste material is jumped out when preventing punch forming.
The utility model solves the technical scheme that its technical problem adopts: diel, comprises punch, die, as stamping material thickness >=0.8mm, described die mould knife-edge part is provided with bulge-structure; As stamping material thickness≤0.8mm, described die mould knife-edge part is provided with sunk structure.
Further, described bulge-structure is ball arc structure.
Further, described sunk structure is ball arc structure.
Further, described bulge-structure protrusion direction is in the horizontal direction, is highly 0.02mm.
Further, described sunk structure depression direction is in the horizontal direction, and the degree of depth is 0.015mm.
Further, when punch forming is circular hole, described bulge-structure or sunk structure at least arrange 3, and set-up mode is for being evenly distributed on mould edge of a knife distribution circle.
Further, when punch forming is profiled holes, described bulge-structure or the every bar limit of sunk structure at least arrange 1.
Further, described die inside groove is in vertical direction with certain angle α, and this angular dimension is 1.5 °.
The beneficial effects of the utility model are: by being provided with bulge-structure or sunk structure at die mould knife-edge part, die inside groove surface roughness is increased, increase the frictional force on surface, to punch forming product produce scrap-bounce time play barrier effect, waste material can not be jumped out, avoid product and jump out due to waste material and caused to weigh wounded, damage, reduce the rework rate of product, scrappage, improve production efficiency, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view that die mould knife-edge part of the present utility model is set to bulge-structure.
Fig. 2 is the longitudinal sectional view that die mould knife-edge part of the present utility model is set to sunk structure.
Mark in figure: punch 1, die 2, material 3, projective structure 4, sunk structure 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model diel, comprises punch 1, die 2, as stamping material 3 thickness >=0.8mm, described die 2 mould knife-edge part is provided with bulge-structure 4; As stamping material 3 thickness≤0.8mm, described die 2 mould knife-edge part is provided with sunk structure 5.
Particularly, the stamping forming blade clearance of material 3 is 5% of material thickness, and punch 1 and the gap of die 2 in punching course are at least greater than 0.02mm, if the gap between them is less than 0.02mm, easily make punch 1 shovel die 2, cause damage each other; Again because when the height of projection of bulge-structure 4 at least wants 0.02mm, could effectively prevent jumping out of waste material, so when drawing material 3 thickness >=0.8mm, die 2 mould knife-edge part is provided with bulge-structure 4, die 2 inside groove surface roughness is increased, increase surface frictional force, to punch forming product produce scrap-bounce time play barrier effect, waste material just can not be knock-oned.As material 3 thickness≤0.8mm, bulge-structure 4 is set punch 1 can be made to shovel die 2, cause damage each other.
Particularly, as stamping material 3 thickness≤0.8mm, die 2 is shoveled for avoiding punch 1, cause damage each other, but also to prevent the rebound of waste material simultaneously, therefore described die 2 mould knife-edge part is provided with sunk structure 5, because as material 3 thickness≤0.8mm, blade clearance between die 2 and punch 1 is less than 0.04mm, and die 2 inside groove is in vertical direction with certain angle, this angular dimension is 1.5 °, die 2 inside groove upper part can be made little relative to lower part, along with punch 1 drift declines, gap becomes large, punch 1 drift rising gap smaller, after being provided with sunk structure 5, die 2 inside groove surface roughness is increased, increase the frictional force on surface, to punch forming product produce scrap-bounce time play barrier effect, waste material just can not be knock-oned.
Preferably, described bulge-structure 4 is ball arc structure, ball arc structure handling ease, and stabilized structure, round and smooth, intensity is large.
Preferably, described sunk structure is ball arc structure 5, ball arc structure handling ease, and stabilized structure, round and smooth, intensity is large.
Further, described bulge-structure 4 protrusion direction is in the horizontal direction, is highly 0.02mm.Draw through test of many times and practical studies, when bulge-structure 4 is highly less than 0.02mm, the rebound of waste material can not be prevented completely, when height of projection is at least 0.2mm, scrap-bounce can be prevented, but being greater than 0.02mm makes the gap between die 2 and punch 1 reduce, and may easily cause mutual damage, the height of the bulge-structure that the utility model is arranged is 0.02mm.
Further, described sunk structure 5 caves in direction in the horizontal direction, and the degree of depth is 0.15mm.Sunk structure 5 is to increase die 2 inside groove surface roughness, increase the frictional force on surface, when being set to sunk structure 5, gap between punch 1 and die 2 increases, mutual loss can not be there is, draw in conjunction with in the complexity of processing and practice, the sunk structure that the utility model is arranged is 0.15mm.
Preferably, when punch forming is circular hole, described bulge-structure 4 or sunk structure 5 at least arrange 3, play set-up mode for being evenly distributed on mould edge of a knife distribution circle.
Preferably, when punch forming is profiled holes, described bulge-structure 4 or the every bar limit of sunk structure 5 at least arrange 1.As quadrangle, die 2 mould edge of a knife quadrangularly, every bar limit at least arranges 1 projection 4 structure or sunk structure 5.
Preferably, described die 2 inside groove is in vertical direction with certain angle α, and this angular dimension is 1.5 °.Arrange like this and die 2 inside groove upper part can be made little relative to lower part, along with punch 1 drift declines, gap becomes large gradually, and punch 1 drift rising gap diminishes gradually, plays certain restriction to the rebound of waste material.
