Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, in conjunction with accompanying drawing 1 and accompanying drawing 2
Further description is made to the present invention.
The invention provides a kind of cylindrical steel shell lithium battery seal combines upper mould, its feature is the invention provides a kind of cylinder
The upper mould of steel shell lithium battery sealing combination, it is characterised in that：The upper mould base 1 includes fixing end and hand-held boss, and fixing end is
Mould is provided with annular anchoring groove on cylindrical structural, and hand-held boss is similarly cylindrical structural, and hand-held boss is with diameter greater than fixation
End diameter, hand-held boss cylinder round and in position has installed inner membrance installing blind, and blind hole lower section is provided with the hole of bolt 7
The lower section of the upper mould base 1 is provided with ebonite pad 2, and the external diameter of ebonite pad 2 is identical with the hand-held boss of upper mould base 1, ebonite pad 2
With certain elasticity, inside is provided with the interspersed through hole of internal model
The lower section of the ebonite pad 2 is provided with cover die base 3, the cover die base 3, in cylindrical structural, external diameter and the external diameter of ebonite pad 2
It is identical, and base rice screw hole is provided with, inside is provided with a cover die slot, and cover die slot top is provided with internal model slot, on internal model slot
There is internal model limiting stand side, and internal model inserting hole is provided with internal model limiting stand.
Cover die 4 is inserted with the cover die slot of the cover die base 3, cover die 4 is fixed on cover die base 3 by base rice screw 5
On, it is in circular ring structure that cover die 4 is overall, and external diameter is identical with cover die slot diameter, and internal diameter is identical with internal model slot diameter, and cover die 4 is consolidated
After fixed, lower section it is slightly longer go out lower mould base, grow partial interior and dig the battery for having 0.5 ~ 1MM bigger than interior strength and penetrate groove, groove top
There are 45 ~ 75 degree of chamferings
Internal model 6 is all cased with the cover die 4, cover die base 3, ebonite pad 2, the internal model 6 includes staking punch and fixed handle, described
The external diameter of staking punch is identical with the internal diameter of cover die 4, and staking punch bottom is provided with R angles, and the height and battery at R angles penetrate groove chamfer height one
Cause, the external diameter of fixed handle is identical with the diameter of internal inserting hole, and hexagon socket head cap screw hole is provided with inside internal model 6
The mould is made using Cr12, and processes through surface hardening.
The present invention is fixed on decompressor by calling the fixing end of mould base, and battery is sent to into the bottom immediately below upper mould
On mould, after battery location is fixed, decompressor drives upper mould to be pressed downward, and during pushing, battery contacts first cover die
Battery penetrates groove and a little deformation inwardly occurs, and the staking punch of internal model is contacted afterwards, and staking punch is provided with R angles, can facilitate battery
After box hat contact staking punch, smooth generation deformation during battery steel shell produces deformation, has embodied this combination die
Advantage, during upper mould is pressed downward, under the stress of battery steel shell, inner membrance is subject to a reaction force upwards,
So as to compress cover die base, and then ebonite pad is compressed, ebonite pad compresses because of stress, in the process, battery case is a bit
Point deformation further completes sealing, enlarging will not occurs because of accepting excessive, fried mouth, situations such as oral area deforms, after sealing, and punching
Pressure device drives and moved on upper mould, and in order to prevent cover die from blocking box hat, battery ejection is completed once to seal by the downward elastic force of ebonite pad
Mouthful operation, now takes out on battery, sends into and new treats that sealed battery repeats aforesaid operations.
