Supporter 1 and 2 connection relation of raised body are secured, and are that a part passes through by the different component integration of two kinds of shapes and structure
It integrally prepares moulding technique to be produced, original welding procedure can be saved, molding die quantity can also be reduced, from
And effectively reduce manufacturing cost.
In another embodiment of the present invention, which further comprises：Plank 14 is punched, riveting is formed
Connect hole.
Specifically, in order to meet the structure design demand of power battery plate, during being molded power battery plate
The step of needing setting to form riveted holes.
In addition to this, which can also include blinking scrap, be punched the process of correcting hole.Herein, punching is useless
Material can be a step incessantly, can be multiple steps, be interspersed in it is entire it is molding during, it can be for shape to act on
Can also be that can also be to meet the size requirements of power battery plate in order to make power at the region of fixed plate 14
Battery pole plates fall off from plank 14.
It is punched correcting hole, improper movement can occur during integrally preparing molding to avoid plank 14, to really
Protect the machining accuracy of power battery plate.
In addition, the punching of above-mentioned riveted holes can be the punching carried out on the basis of the correcting hole of part.
In another embodiment of the present invention, molding die includes：Upper mold 13, setting fluted 13.1, for holding
Receive raised body 2；Lower mold 15, is provided with correcting needle 15.1, the correcting hole for interting plank 14；Wherein, upper mold 13 is also set
It is equipped with the first press section 13.2, lower mold 15 is additionally provided with the second press section 15.2, the first press section 13.2 and the second press section
15.2 is vertical corresponding, and raised body 2 and supporter 1 are formed for extrusion plate 14.
Specifically, it can be stamping equipment that one, which prepares molding equipment, wherein stamping equipment may include molding die
And Lifting Device.For example, as shown in Fig. 2, Lifting Device may be used to lower mold 15 moves in the vertical direction, so as to lower die
The correcting needle 15.1 of tool 15 can be detached with plank 14.Function for molding die and effect, can be with 2 embodiment of reference chart
Description, in order to avoid repeating, which is not described herein again.
With reference to specific example, it is described more fully the embodiment of the present invention.
Fig. 5 is the schematic process diagram of the manufacturing method of power battery plate in accordance with another embodiment of the present invention.Its
In, executive agent can be former.
505, plank 14 is punched, waste material is removed.
Blinking scrap is carried out to plank 14, on the one hand can remove extra waste material, on the other hand so as in subsequent step
Stamping equipment can be with fixed plate 14 in rapid.
510, plank 14 is punched, correcting hole is formed.
Correcting hole is formed, can be interspersed in correcting hole so as to the correcting needle 15.1 of lower mold 15, and then prevent follow-up
The step of in plank 14 improper movement occurs.
515, plank 14 is punched, primary extruding zones of extensibility is formed.
It is formed and squeezes zones of extensibility, so that during subsequent extrusion plank 14, plank 14 has enough spaces to carry out shape
Become and extends.
520, plank 14 is squeezed, a part for raised body 2 is preliminarily formed.
In order to ensure molding effect, the mode that multistep extruding may be used is molded.Specifically, here multistep squeeze
Number can be for three times, wherein step 520 can be first time extrusion forming.
525, plank 14 is squeezed, forms a part for raised body 2 again.
Step 525 can be second of extrusion forming.
530, plank 14 is punched, secondary extrusion zones of extensibility is formed.
Herein, due to experienced compressional deformation extension twice, the primary remaining space in zones of extensibility that squeezes may be not enough to
It supports the compressional deformation of next time, therefore is punched again to once squeezing zones of extensibility, form secondary extrusion zones of extensibility.It should manage
Solution, primary extruding zones of extensibility can be identical with the position of secondary extrusion zones of extensibility and size, can not also be identical.
535, plank 14 is squeezed, the raised body 2 for finally meeting size requirements is formed.
Step 535 can be third time extrusion forming.
540, plank 14 is punched, secondary removal waste material.
Herein, blinking scrap is carried out again to secondary extrusion zones of extensibility, current punching is punched for precision, to be formed
Meet the supporter 1 of size requirements.
545, plank 14 is punched, riveted holes 2.4 are formed.
In the correcting hole that step 510 is formed, there is part correcting hole to can be used for being formed riveted holes 2.4.To these correctings
Hole is punched, to form riveted holes 2.4.
550, plank 14 is punched, blanking, forms power battery plate.
In step 540, the both sides opposite to supporter 1 carry out precision punching, remove waste material, so that the both sides is met corresponding
Size requirements.In step 550, precision punching is carried out to the other opposite both sides of supporter 1, waste material is removed, keeps them full
The corresponding size requirements of foot, can also be such that molding power battery plate is detached from from plank 14.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Within god and principle, made by any modification, equivalent replacement etc., should all be included in the protection scope of the present invention.
