Abstract
The manufacture method includes manufacture of tube in certain length, drawing to two sides of the tube into tube in required shape using the special mold; and welding, adhering or mechanical deformation in two ends to add two bottoms and to form sealed casing for battery. The casing thus manufactured has high mechanical strength and great width-to-thickness ratio, and the manufacture process is simple, low in cost and low in investment.
Description
The present invention relates to the battery manufacturing technology, relate in particular to a kind of manufacture method of novel battery casing.
The process technology of existing battery case is generally used the manufacturing of whole punching stretch method, this method machining accuracy is poor, mechanical strength is low, flakiness ratio is little, play flakiness ratio W: T and can only reach 2: 1 (see figure 6)s usually, simultaneously, big to the mould development difficulty of the battery case of special-shaped size, to make fund input also big, what more become problem is that the construction cycle is long.
The object of the present invention is to provide a kind of method of new manufacturing battery case, this method can overcome the above-mentioned shortcoming of prior art, and it utilizes cold stretch to increase mechanical strength, guarantee the precision of battery case by mould and die accuracy, simultaneously, mould is simple, less investment, with short production cycle.
The manufacture method of a kind of novel battery casing provided by the invention is characterized in that, may further comprise the steps: the pipe of preparation predetermined length logical (logical as ellipse), lead to both sides to described pipe with special mould and be drawn into the cylindrical shell (as square tube) that requires shape; Add that by methods such as welding, bonding and mechanical deformations two base plates form a square sealing battery shell at the both ends of described cylindrical shell.
Wherein, the pipe of described preparation predetermined length is logical may further comprise the steps: cutting into required height H as the raw material pipe; When needing, the pipe of height H is pressed into flat pipe in advance leads to.
In addition, also be included in cylindrical shell just, the back side makes a call to the step that a horizontal seal is made (comprising square seal, circle or oval seal, netted escutcheon and other shape seal) reinforcement.
Wherein, described welding method can be methods such as Laser Welding, inferior arc-welding and beam-plasma.
Wherein, described base plate can adopt stainless steel, iron or metals such as aluminium and aluminium alloy.
Wherein, described pipe is led to both sides at the special mould of described usefulness and be drawn in the step of cylindrical shell of requirement, described special mould comprises wedge type patrix and oblique contract type counterdie, and described counterdie mainly is made up of two or slide block and stopping means.
Implement battery case manufacture method provided by the invention, its product has the mould that mechanical strength height, big, the whole process of flakiness ratio use than the battery case of the whole punching stretch of traditional moulds and technology is simple and exploitation, make advantages such as less investment, speed are fast.
Below in conjunction with drawings and Examples, method of the present invention is described in further detail, in the accompanying drawing:
Fig. 1 is the process flow diagram of the manufacture method of a kind of novel battery casing provided by the invention;
Fig. 2 is illustrated in the situation about being pressed into before and after oval logical flexible of carrying out;
Fig. 3 is illustrated in ellipse is logical when making square tube used mould and shaping situation;
Fig. 4 illustrates 4 kinds of common structural representations of the battery case that the inventive method produces;
Fig. 5 illustrates the structural representation that battery case that the inventive method produces is provided with reinforcement;
Fig. 6 is the battery case structural representation of explanation flakiness ratio.
As shown in Figure 1, the manufacture method of a kind of battery case provided by the invention: at first logical (as round steel pipe) (frame 101) cutting of raw material pipe (frame 102) is become required height H; Then the stock material shapes pipe that highly is H logical (being round steel pipe herein) precompressed (frame 103) is become flat pipe logical (herein for oval logical), its process as shown in Figure 2; Again the logical counterdie that is inserted in of this flattened oval, move downward with patrix, the logical square tube (frame 104) that is stretched as of ellipse, (its process as shown in Figure 3), the step that can select is the frame 105 described reinforcements of beating, in frame 106, the cylindrical shell that forms is carried out end face to be cut out and makes its length identical, simultaneously thin plate (frame 109) is struck out base plate (frame 110), base plate is attached in some way to an end (frame 107) of cylindrical shell, at this moment, can carry out battery dress shell to the cylindrical shell of band base plate is filling content (frame 108), meanwhile, thin plate (frame 111) is carried out punching press (frame 112), strike out loam cake, in the welded top (frame 113) of square tube, just formed a quad seal novel battery then.
In the present embodiment, described method be included in cylindrical shell (as square tube) just, the back side makes a call to the method that a horizontal seal is made reinforcement (frame 105), as shown in Figure 5.
In the present embodiment, be flat tube logical (logical or square tube) as raw material as ellipse, then can save prepressing procedures, directly get final product after the cutting with die drawn.
As shown in Figure 3, in an embodiment of the present invention, the mould that is adopted comprises patrix 301 and counterdie, and patrix 301 is a wedge, and counterdie mainly is made up of oblique contract type slide block 302 and stopping means 303.
Fig. 4 illustrates 4 kinds of common structural representation situations utilizing the battery case that the inventive method produces.As shown in the figure, first kind is full rectangular enclosure, second kind is that both sides are circular arc, parallel lines connects between two circular arcs, the third is that a side is a circular arc, and opposite side is a rectangle, is connected by parallel lines between rectangle and the circular arc, the 4th kind is that both sides are rectangle, is connected with camber line by straight line respectively between the rectangle both sides.From then on as seen, utilize the battery case of the inventive method manufacturing can produce the battery case of different profiles.
