Abstract
The invention discloses a secondary composite die. The secondary composite die comprises a die C and a die D. A die C upper die punch pin is arranged in the corresponding position above the die C. The die C comprises an inner die and a primary composite outer die. The inner die is sleeved with the primary composite outer die to form a combined lower die. A die D upper die punch pin is arranged in the corresponding position above the die D. The die C and the die D are combined to form the secondary composite die. The primary composite outer die is cylindrical. The outer side of the bottom of the primary composite outer die is provided with a convex ring. The inner side of the bottom of the primary composite outer die is provided with an expansion port. The inner side of the top of the primary composite outer die is provided with a snap ring inclining inwards. The inner die is cylindrical. The outer side of the bottom of the inner die is provided with an inner die convex ring. The inner side of the top of the inner die is provided with an inner die snap ring inclining inwards. The outer diameter of the inner die convex ring of the inner die is greater than the inner diameter of the primary composite outer die and less than the outer diameter of the convex ring. The die D is cylindrical. The outer side of the bottom of the die D is provided with a die D convex ring. The inner side of the top of the die D is provided with a die D snap ring inclining inwards.
Description
Technical field
The invention belongs to technical field of mold, especially secondary composite die.
Background technology
At present production battery steel shell using be all gradual continuous common die, 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, wall thickness causes box hat capacity little, it is impossible to meet existing great Rong
The basic demand of amount lithium battery steel shell.
Content of the invention
It is contemplated that overcoming the defect of prior art, the present invention designs a kind of secondary composite die, fast with molding, chi
Very little control more accurate and can secondary punching different wall rounding off novel steel-shelled advantage.
In order to solve above-mentioned technical problem, the present invention provides technical scheme below：
A kind of secondary composite die, including C mould, D mould, above C mould, corresponding section is provided with C mould upper punch core, C mould
Including internal model and once-combined external mold, once-combined external mold is socketed in internal model becomes mould under combination type；Relative above D mould
Should place be provided with D mould upper punch core, C mould, D die assembly 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, on the inside of once-combined outer mold top, be provided with the oblique snap ring of inside inclination.
Further, internal model is cylindrical, and internal model bottom outside is provided with internal model bulge loop, inside top and is provided with inside inclination tiltedly
Internal model snap ring.
Further, the internal model bulge loop external diameter of internal model more than once-combined external mold internal diameter and is less than bulge loop external diameter.
Further, D mould is cylindrical, is provided with D mould bulge loop, inside top and is provided with inside inclination on the outside of D mold bottom
Oblique D mould snap ring.
Compared with prior art, the present invention has following beneficial effect：
The innovation of the common die of script is fast Novel combination mold, with molding by the present invention, and size Control is more accurate and can
The advantage of the rounding off novel steel-shelled of secondary punching different wall.Citing：Script common die can only produce 0.25mm wall thickness
Box hat, secondary composite die can produce two kinds of different wall of 0.25mm and 0.15mm wall thickness through rounding off be embodied in
Box hat on one.Further by the thinning of wall thickness, volume is produced greatly, the big New Type of Differential thicker box hat of capacity, meet existing
Demand condition in the high-capacity lithium battery of day by day demand.
Description of the drawings
Fig. 1 is the structural representation of the secondary composite die of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and the present invention is explained, be not intended to limit the present invention.
As shown in figure 1, a kind of secondary composite die, is provided with C including corresponding section above C mould 1, D mould 2, C mould
Mould upper punch core 3, C mould includes internal model 11 and once-combined external mold 12, and once-combined external mold is socketed in internal model becomes combination
Mould under formula；It is cylindrical that 2 top corresponding section of D mould is provided with D mould upper punch core 4, D mould, is provided with D mould on the outside of D mold bottom
Bulge loop, inside top are provided with the oblique D mould snap ring of inside inclination.C mould 1, D mould 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 and on the inside of outer mold top, be provided with the oblique snap ring of inside inclination；Internal model is cylindrical, and internal model bottom outside is provided with internal model bulge loop, top
The oblique internal model snap ring of inside inclination is provided with the inside of portion.The internal model bulge loop external diameter of internal model more than once-combined external mold internal diameter and is less than
Bulge loop external diameter.
Using two sets of combination type lower die structures of segmentation, mould innovation under originally single integral type is mould under combination type,
By the combination of internal model and two mold of once-combined external mold, during punching box hat, upper punch core is by steel band through group
Two sections of box-like lower mould stretchings, 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 mouldD mouldAgain punching press once,
Between making different wall, ladder is thinning and rounder and more smooth, and secondary composite abrasive product is not that stepped separation has transition up and down,
The stepped thickness of once-combined grinding tool product is distinguished obvious.
Explanation embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the technology of this area
For personnel, all any modification, equivalent substitution and improvement that within the spirit and principles in the present invention, is made etc., should be included in
Within protection scope of the present invention.
