Abstract
The utility model discloses a die cutting device for manufacturing a lithium cell, which comprises a lower template and an upper template, wherein the lower template is provided with two die cutting openings, and the upper template comprises two die cutting blocks which are correspondingly fitted, inserted and matched with the die cutting openings; and each die cutting opening consists of an upper vertical cutting edge part and a lower inclined part, and each inclined part is inclined towards the direction which is far away from the center from top to bottom. By adopting the technical scheme that the lower template is provided with the die cutting openings, the die cutting device leads a plurality of slices to be directly fallen and discharged from the bottoms of the die cutting openings after the die is cut without needing of the next cutting treatment, thereby improving the production efficiency. Furthermore, by adopting the technical scheme that the bottoms of the die cutting openings at the two sides are inclined, the die cutting device increases the depth of the bottom of a separated rib between the two adjoining die cutting openings to improve the mechanical strength of the separated rib on the premise that the base material is not wasted, and is easy to separate the fallen and discharged slices since the distances of the openings at the bottoms of the two adjoining die cutting openings are larger.
Description
Technical field
The utility model relates to a kind of lithium battery production die-cutting apparatus.
Background technology
In the lithium battery processing industry, battery material needs to carry out cross cutting after coating handles, and normally used die-cutting apparatus comprises lower bolster and cope match-plate pattern as shown in Figure 1, arranges on lower bolster 3 and is provided with three vertical cross cutting grooves 2; Cope match-plate pattern comprises the rectangular mold stripping and slicing 1 with the 2 corresponding grafting of cross cutting groove, and the preceding bottom of cross cutting piece 1 is provided with breach 7.Matrix material places the upper surface of lower bolster when cross cutting is handled, with the downward punching press of cross cutting piece, matrix material 4 is cut into three and cuts off the section 5 that one side keeps, as shown in Figure 2, the arrow direction is the direct of travel of matrix material among the figure, drag the matrix material 45 cross cutting grooves 2 of taking lower bolster out of of will cutting into slices, carry out next step to keeping the cut-out at position 6, finally obtain cutting into slices 5.Adopt the die-cutting process complexity of this template, matrix material need carry out cutting twice just can obtain section, and technology is comparatively complicated, and production cost is higher.
The utility model content
The purpose of this utility model provides a kind of lithium battery production die-cutting apparatus that can a shape by die-cutting, to improve the efficient of producing, reduces production costs.
In order to realize above purpose, the technical scheme that the utility model adopted is: a kind of lithium battery production die-cutting apparatus, comprise lower bolster and cope match-plate pattern, arrange on the described lower bolster and be provided with two die cut that described cope match-plate pattern comprises the corresponding cross cutting piece that coincide and peg graft and cooperate with die cut; Described two die cut are to be made of the vertical cutting edge part on top and the sloping portion of bottom, and this sloping portion tilts to deep direction from top to bottom.
Another technical scheme that the utility model adopted is: a kind of lithium battery production die-cutting apparatus, comprise lower bolster and cope match-plate pattern, and to arrange on the described lower bolster and be provided with three die cut, described cope match-plate pattern comprises the corresponding cross cutting piece that coincide and peg graft and cooperate with die cut; Described two die cut that are in both sides are to be made of the vertical cutting edge part on top and the sloping portion of bottom, and this sloping portion tilts to deep direction from top to bottom.
Another technical scheme that the utility model adopted is: a kind of lithium battery production die-cutting apparatus, comprise lower bolster and cope match-plate pattern, and to arrange on the described lower bolster and be provided with five die cut, described cope match-plate pattern comprises the corresponding cross cutting piece that coincide and peg graft and cooperate with die cut; Described four die cut that are in both sides are to be made of the vertical cutting edge part on top and the sloping portion of bottom, and this sloping portion tilts to deep direction from top to bottom, and the angle of inclination to both sides increases gradually from the center.
The described die cut that mediates is vertical die cut.
Lithium battery production die-cutting apparatus of the present utility model adopts the technical scheme offer die cut on lower bolster, and the section behind the cross cutting is directly from whereabouts, the bottom discharging of die cut, a shape by die-cutting, need not to carry out next step cut-out processing, improved the efficient of producing, reduced production cost.In addition, employing is in the technical scheme of the die cut bottom angled of both sides, improved the thickness of the muscle bottom between adjacent two die cut on the one hand, under the prerequisite of not wasting matrix material, improved the mechanical strength of muscle, the interval of adjacent on the other hand two die cut bottom openings is bigger, and the section of whereabouts discharging separates easily.

The specific embodiment
Lithium battery production die-cutting apparatus of the present utility model, shown in Fig. 3,4, comprise lower bolster 12 and cope match-plate pattern, arrange on this lower bolster 12 and be provided with three die cut 15,16,17 that described cope match-plate pattern comprises three cross cutting pieces 10 that coincide and peg graft and cooperate with corresponding die cut; The described die cut the 15, the 17th that is in both sides, by top be used for and the peg graft vertical part 13 that cooperates and the sloping portion 14 of bottom of cross cutting piece 10 formed, to deep direction inclination, die cut 16 is vertical die cut to this sloping portion 14 from top to bottom.
As shown in Figure 5, the difference of present embodiment and embodiment 1 is: arrange on the lower bolster 12 and be provided with five die cut, the bottom of die cut 21,22,23,24 that wherein is in both sides is for being obliquely installed, and wherein the angle of inclination of the sloping portion of die cut 22,24 is greater than the sloping portion of die cut 21,23.Die cut 25 is vertical die cut.
As shown in Figure 6, the difference of present embodiment and embodiment 1 is: arrange on the lower bolster 12 and be provided with two die cut 31,32, these two die cut 31,32 tilt to deep direction respectively from top to bottom.
