The apparatus for shaping of the battery roll core of embodiment belongs to the precompressed shaping of battery roll core 30, the also hot pressing shaping after pre-shaped,
That is, precompressed is first carried out before hot pressing battery roll core 30, so that the shape of battery roll core 30 tentatively changes.This is practical new
In type embodiment, inside of the tracheae 40 for the battery roll core 30 in supporting table 10 is blown, referring to Fig. 4, battery roll core 30
Diaphragm head 301 be attached at battery roll core 30 under the action of the air-flow of tracheae 40 inner wall 30a on, in this way, supporting table 10
With fitting 20 during squeezing battery roll core 30, the diaphragm head 301 inside battery roll core 30 is not in folding feelings
Condition；In subsequent hot pressing reforming process, since the inner wall 30a of battery roll core 30 has been close on diaphragm head 301 completely, because
This, can preferably prevent it is in the prior art folded because of diaphragm head 301 caused by pole piece in hot pressing reforming process rise
Wrinkle or decarburization problem.Furthermore in the prior art, diaphragm head 1 ' may be exposed one small from core axial direction side when squeezing
Angle needs manually to do over again at this time, and the exposed small angle of diaphragm is wiped out, and so will increase workload and influences efficiency, this is practical new
The apparatus for shaping of the battery roll core of type embodiment, diaphragm head 301 are attached on the inner wall 30a of battery roll core 30, extrusion process
In can preferably prevent diaphragm head 301 along the exposed small angle of the axial direction of battery roll core 30.
Supporting table 10 and fitting 20 are horizontally disposed, and supporting table 10 is located at the lower section of fitting 20, and battery roll core 30 can
Relative reliability is placed in supporting table 10.
The above-mentioned supporting table 10 and the fitting 20 can be movable relatively, and it is motionless to can be supporting table 10, fitting
20 movements；It is also possible to the movement of supporting table 10, fitting 20 is motionless；It can also be that supporting table 10 and fitting 20 move.This
In embodiment, supporting table 10 and fitting 20 are moved, and specifically, apparatus for shaping includes the first actuator (not shown) and second
Actuator (not shown), the first actuator and supporting table 10 are drivingly connected, to drive supporting table 10 vertically moving, example
Such as, the first actuator driving supporting table 10 moves up to predetermined position from initial position, to accept the electricity for completing a upper process
Pond core 30, battery roll core 30 are carried in supporting table 10, and subsequent supporting table 10 moves downwardly to initial position.Second actuator
It is drivingly connected with fitting 20 to drive 20 horizontal movement of fitting, when supporting table 10 needs to move up and down, 20 edge of fitting
Horizontal motion interferes to avoid with supporting table 10.
Tracheae 40 is connect with fitting 20, so the connected support structure without additional setting tracheae 40, can simplify knot
Structure.It is understood that tracheae 40 also can follow fitting 20 to move synchronously when fitting 20 moves.
The structure of fitting 20 is unlimited, can be tabular, is also possible to column, can also be column and planar knot
Close etc..
When the size difference of battery roll core 30, need to adjust the position of the outlet of tracheae 40, for this purpose, the utility model is implemented
In example, the apparatus for shaping of battery roll core includes regulating part 60, and the first side of regulating part 60 is connect with fitting 20, regulating part 60
