Abstract
The utility model discloses a secondary compounding mould, including C mould, D mould, the corresponding department in C mould top is equipped with stamping core on the C mould, and the C mould includes centre form and compound external mold once, and the external mold that once compounds cup joints and become combination formula lower mould on the centre form, the corresponding department in D mould top is equipped with stamping core on the D mould, and C mould, D mode combination get up to constitute secondary compounding mould. The external mold that once compounds is cylindricly, and once the compound external mold bottom outside is equipped with the bulge loop, the bottom inboard is provided with expansion port, and once compound external mold inside of the top of is provided with the inclined snap ring that inwards heels. The centre form is cylindricly, and the centre form bottom outside is equipped with the centre form bulge loop, inside of the top of is provided with the inclined centre form snap ring that inwards heels. The centre form bulge loop external diameter of centre form is greater than once compound external mold internal diameter and is less than the bulge loop external diameter. The D mould is cylindricly, and the D mould bottom outside is equipped with D mould bulge loop, inside of the top of is provided with the inclined D mould snap ring that inwards heels.
Description
Technical field
This utility model belongs to technical field of mold, especially secondary composite die.
Background technology
What at present production battery steel shell was used is all gradual continuous common die, and straight up and down, mould punching is single, only
Common straight wall box hat can be produced, the box hat limitation of production is big, and wall thickness causes box hat capacity little, it is impossible to meet existing great Rong
The basic demand of amount lithium battery steel shell.
Utility model content
This utility model is intended to overcome the defect of prior art, this utility model to design a kind of secondary composite die, have
Molding is fast, size Control it is more accurate and can secondary punching different wall rounding off novel steel-shelled advantage.
In order to solve above-mentioned technical problem, this utility model provides technical scheme below：
A kind of secondary composite die, including C moulds, D moulds, C moulds top corresponding section is provided with C mould upper punch cores, C
Mould includes internal model and once-combined external mold, and once-combined external mold is socketed in internal model becomes mould under combination type；D moulds top
Corresponding section is provided with D mould upper punch cores, and C moulds, D die assemblies get up and constitute secondary composite die.
Further, once-combined external mold is cylindrical, and once-combined external mold bottom outside is provided with bulge loop, bottom inside and arranges
There is extension mouth, once-combined outer mold top inner side is provided with the inclined snap ring in inside side.
Further, internal model is cylindrical, and internal model bottom outside is provided with internal model bulge loop, inside top and is provided with inwardly inclination tiltedly
Internal model snap ring.
Further, the internal model bulge loop external diameter of internal model is more than once-combined external mold internal diameter and less than bulge loop external diameter.
Further, D moulds are cylindrical, and D mold bottoms outside is provided with D mould bulge loops, inside top and is provided with inwardly inclination
Oblique D mould snap rings.
Compared with prior art, this utility model has following beneficial effect：
The common die innovation of script is Novel combination mold by this utility model, and fast with molding, size Control is more smart
It is close and can secondary punching different wall rounding off novel steel-shelled advantage.Citing：Script common die can only be produced
The box hat of 0.25mm wall thickness, secondary composite die can produce two kinds of different walls of 0.25mm and 0.15mm wall thickness through round and smooth mistake
Cross the box hat being embodied on same.Further by the thinning of wall thickness, volume is produced greatly, the big New Type of Differential thicker steel of capacity
Shell, meets now the demand condition of the day by day high-capacity lithium battery of demand.
Description of the drawings
Fig. 1 is the structural representation of the secondary composite die of this utility model.
Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.
As shown in figure 1, a kind of secondary composite die, including C moulds 1, D moulds 2, C moulds top corresponding section is provided with C
Mould upper punch core 3, C moulds include internal model 11 and once-combined external mold 12, and once-combined external mold is socketed in internal model becomes combination
Mould under formula；The top corresponding section of D moulds 2 is provided with D mould upper punch core 4, and D moulds are cylindrical, and D mold bottoms outside is provided with D moulds
Bulge loop, inside top are provided with the inclined D moulds snap ring in inside side.C moulds 1, D moulds 2 combine and constitute secondary composite die.
Once-combined external mold is cylindrical, and once-combined external mold bottom outside is provided with bulge loop, bottom inside and is provided with extension mouth, once multiple
Close outer mold top inner side and be provided with the inclined snap ring in inside side；Internal model is cylindrical, and internal model bottom outside is provided with internal model bulge loop, top
Portion inner side is provided with the inclined internal model snap ring in inside side.The internal model bulge loop external diameter of internal model is more than once-combined external mold internal diameter and is less than
Bulge loop external diameter.
It is mould under combination type by mould innovation under originally single integral type using two sets of combination type lower die structures of segmentation,
By the combination of internal model and the mold of once-combined external mold two, during punching box hat, upper punch core is by steel band through group
Two sections of stretchings of box-like lower mould, and the cooperation of two molds combination, are successfully two sections different wall by moulding steel casing
And have the novel lithium battery box hat of rounding off at different wall.By passing through after C mouldsD mouldsAgain punching press once,
Make ladder between different wall thinning and rounder and more smooth, secondary composite abrasive product is not up and down that stepped separation has transition,
The stepped thickness of once-combined grinding tool product distinguishes obvious.
Explanation embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for ability
It is all within spirit of the present utility model and principle for the technical staff in domain, any modification, equivalent substitution and improvements made
Deng should be included within protection domain of the present utility model.
