Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Fig. 3 is using state schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
As Figure 1-3, the utility model is about a kind of feeding die cutting die smoothly, and comprise lower bolster 1 and an anti-sticking elastic portion 2, this lower bolster 1 is the Lower Half of whole secondary punch die, is namely installed on the punch die part on press bench face, with cope match-plate pattern with the use of.
As Figure 1-3, lower bolster 1 is at least provided with two cutting edges 11, this cutting edge 11 is shaping for cutting of product, this cutting edge 11 edge forms knife edge structure, wherein anti-sticking elastic portion 2 is equipped with in one end at each cutting edge 11, this anti-sticking elastic portion 2 for prevent product cut shaping after send time be stuck in cutting edge 11, gap K is formed between this anti-sticking elastic portion 2 and link of cutting edge 11, the setting of gap K, for the pressurized/resilience of anti-sticking elastic portion 2 provides space, ensure that the result of use of anti-sticking elastic portion 2, this anti-sticking elastic portion 2 top is convexly equipped in cutting edge 11 upper surface, anti-sticking elastic portion 2 passes through projection, effectively shaping product can be ejected cutting edge 11, ensure that product can smooth and easy output.
As Figure 1-3, wherein, anti-sticking elastic portion 2 is connected with cutting edge 11 by a mounting blocks 3, the linkage section 21 that this anti-sticking elastic portion 2 is connected with mounting blocks 3 by one, the section of upspringing 24 that the one pressure-bearing section be connected with linkage section 21 22 and is connected with pressure-bearing section 22 by elastic force section 23 forms, this pressure-bearing section 22 is for bearing the die-cut partial pressure of patrix, this section of upspringing 24 cuts the product of forming for upspringing, the front end of the section of upspringing 24 is to downward-extension, form extension, gap K is formed between the wall that this extension is relative with cutting edge 11, this section of upspringing 24 favours in pressure-bearing section 22, this elastic force section 23 produces deformation when the section of upspringing 24 pressurized, for the section of upspringing 24 provides the elastic force of resilience.
As Figure 1-3, further, the linkage section 21 of anti-sticking elastic portion 2 is mutually vertical with pressure-bearing section 22, and stretch section and the section of upspringing 24 of anti-sticking elastic portion 2 are an arcuate structure, preferably, mounting blocks 3 is provided with connector, and linkage section 21 is provided with screw, and linkage section 21 passes through screw, attachment screw is connected in the connector of mounting blocks 3, screw is connected with screw fit and is only better selection of the present utility model, so that anti-sticking elastic portion 2 is installed, does not give from limit at this.
As Figure 1-3, wherein, anti-sticking elastic portion 2 is a shell fragment, the width of this anti-sticking elastic portion 2 is 1/4 ~ 1/5 of cutting edge 11 length, if anti-sticking elastic portion 2 width is too small, elasticity is not enough, product can not be ejected, still easily occur that product is stuck on cutting edge 11, affect product and normally export, if anti-sticking elastic portion 2 width is excessive, affect the shaping of product, through experiment test, anti-sticking elastic portion 2 width is 1/4 ~ 1/5 of cutting edge 11 length, preferably by the output of products after shaping, can ensure that the smooth and easy of operation carries out.
As Figure 1-3, anti-sticking elastic portion 2 top protrusion height is 0.3 ~ 1mm, and anti-sticking elastic portion 2 top protrusion height is too small, and it ejects effect is zero substantially, still easily occur in production process that product is stuck on cutting edge 11, affect product normally to export, if anti-sticking elastic portion 2 top protrusion height is excessive, output of products is not steady, through experiment test, anti-sticking elastic portion 2 top protrusion height is that 0.3 ~ 1mm result of use is better, preferably by the output of products after shaping, can ensure that carrying out smoothly of operation.
As Figure 1-3, if the thickness of this anti-sticking elastic portion 2 is 0.1 ~ 0.2mm, the thickness of anti-sticking elastic portion 2 can affect the elasticity of anti-sticking elastic portion 2 itself, through experiment test, thickness is that the anti-sticking elastic portion 2 of 0.1 ~ 0.2mm preferably by the smooth and easy output cutting edge 11 of product after shaping, effectively can avoid snap gauge.
In use, when the downward punching press of cope match-plate pattern, under the effect of cutting edge 11, shaped article enters cutting edge 11, now, due to the pressure of cope match-plate pattern, the section of upspringing 24 of anti-sticking elastic portion 2 is made to be forced to press down, elastic force section 23 compressive deformation, forms elastic stress in elastic force section 23, when cope match-plate pattern resets, elastic force section 23 is under elastic stress effect, recover original state, while elastic force section 23 is recovered, drive the section of upspringing 24 resilience, product in jack-up cutting edge 11, effectively prevent snap gauge, ensure that the smooth and easy output of product, ensure that operation is normally carried out.
It should be noted that, a kind of feeding die cutting die smoothly that the utility model discloses, its scope of application is not limited in the making of battery pole piece, and user can adopt the utility model according to actual needs, and the utility model does not give from limit at this.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is limited; therefore under the prerequisite not departing from the utility model design spirit; the equivalence change that the common engineers and technicians in this area do structure described in the utility model, feature and principle or decoration, all should fall in protection domain that the utility model applies for a patent.
