Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, the invention proposes a kind of piers of battery cover board to press method, comprising steps of
S0, raw material are sliced it is preforming.
S1, the shaping station that workpiece former material is put into pier compression mould, former material pier is molded, once obtains having specified protrusion
And the workpiece of recess.
S2, molding workpiece is punched out, once obtains the workpiece with designation hole.
Pier pressure and one-off hole-piercing are carried out to workpiece, to obtain qualified workpiece, in whole process, only there are two letters
Single technique, does not need that pressing sheet material is repeated, and using the method for pier pressure, material can generate Plastic Flow, therefore material benefit
With rate 95% or more, production cost is greatly reduced, has method simple, is easily mastered, is convenient for the advantages of promoting.
In embodiments of the present invention, in the step S0, further include the steps that carrying out surplus processing to workpiece former material.Surplus
The volume that processing can be such that workpiece possesses in pier pressure, during pier pressure, workpiece flows in mold, thickness and structure
It changes, surplus processing is to supply raw material thickness variation.If not carrying out surplus processing to former material, former material is pressed through in pier
Cheng Zhong when being drawn or cut by mold, can make thickness change, slight crack, situation occurs in inside workpiece because former material does not have surplus
When serious, it may occur however that the case where cutting or breaking.
In embodiments of the present invention, described the step of carrying out surplus processing to workpiece former material includes: to fit in pier compression mould
It answers and bending machining is carried out to workpiece former material under size.Workpiece former material is set to possess surplus, workpiece former material edge ruler by bending machining
It is exactly the surplus of workpiece former material by the amount bent out in the case that the very little size with pier compression mould adapts to.
In embodiments of the present invention, carrying out bending machining to workpiece former material includes: that workpiece former material is bent into arc.Bending
Processing obtains arc-shaped workpiece former material, and arc-shaped workpiece former material facilitates processing, while convenient for being placed into the pier station of pier compression mould.
In embodiments of the present invention, carrying out bending machining to workpiece former material includes: that workpiece former material is bent into waveform.It is curved
Qu Jiagong obtains waveform workpiece former material, and the flexure plane of waveform workpiece original part is more, and the surplus of acquisition is larger.
Specifically, carrying out surplus processing to former material first in the pier pressure method of battery cover board, make former material that there is bending knot
The surplus of structure can generate Plastic Flow during pier pressure, and former material is put on the pier pressure station of pier compression mould, pier pressing mold is used
Have pier and extrude the workpiece with specified protrusion and recess, this process only needs once, to obtain shaping workpiece, do not need repetition into
Row, is then punched out to molding, equally, this process only needs once, to obtain workpiece with holes.
As Figure 2-3, a kind of former material for pier pressure method is provided, the former material setting has a margin structure.Former material is gathered around
Structure is had a margin, the volume of former material can be increased, during pier pressure, if former material does not have surplus, is being drawn or is being cut by mold
When, can thickness be made to change, slight crack occurs in inside workpiece, when situation is serious, it may occur however that the case where cutting or breaking.
In embodiments of the present invention, the surplus structure is warp architecture.Warp architecture can increase the surplus of former material, and
Surplus structure is obtained by bending, surplus utilization rate is high, and utilization rate is up to 95% or more.
Certainly, the surplus structure is also possible to structure thicker, and the thickness for increasing former material also can increase surplus.
In embodiments of the present invention, the former material is the plate of arc-shaped bend.The workpiece former material of arc-shaped bend structure 1, it is remaining
Amount is arc-shaped curvature portion, and arc-shaped workpiece former material facilitates processing, while convenient for being placed into the pier station of pier compression mould.
Further, the arc-shaped bend structure 1 can be single side arc-shaped bend structure, can also with double side arc shaped structure,
It is preferably double side arc shaped warp architecture in the present embodiment.
In embodiments of the present invention, the former material is the curved plate of waveform.The workpiece of the waveform warp architecture 2
Former material, surplus are waveform bending section, and the flexure plane of waveform workpiece former material is more, and the surplus of acquisition is larger.
Further, the waveform warp architecture 2 can be single-face corrugated shape warp architecture, can also be with two-sided waveform
Warp architecture, preferably two-sided waveform warp architecture in the present embodiment.
As shown in figure 4, providing a kind of battery cover board 3, the battery cover board 3 presses method to manufacture by aforementioned any pier
At.In manufacture production process, as soon as the battery cover board 3 molded by time pier, one-off hole-piercing be can be obtained, material use
