The groove rounded at the edge radius R of said clamping plate
1Between 0.5 ~ 2.5mm.
The recess edge radius of corner R of said die
2Between 1.5 ~ 3.5mm, more bigger than clamping plate groove rounded at the edge radius; Between the groove medial surface of die and the lateral surface of punch 0.5 ~ 2mm gap is arranged.
Other radiuss of corner r on said punch, clamping plate and the die is between 1 ~ 3mm.
Surface roughness Ra < the 2 μ m of the groove side surface of said punch lateral surface and lower surface, said clamping plate groove inner surface and die and lower surface; Clamping plate bottom surface and die end face surface roughness Ra < 9 μ m.
The good effect of the utility model is that it utilizes the simple diel of a cover can accomplish the punching course of aluminum-plastic composite membrane, and is simple in structure, and processing ease is applicable to the manual punching press of aluminum plastic film of various soft-package batteries.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the punch structure sketch map of the utility model.
Fig. 3 is the vertical view of the clamping plate of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further: like Fig. 1,2, shown in 3; A kind of soft-package battery is used the aluminum-plastic composite membrane diel; Comprise punch 1, clamping plate 2 and die 3; Alignment pin 4, screw 5 is formed, and it is characterized in that: dowel hole is arranged on the diagonal angle of clamping plate 2 and die 3; Screw hole is evenly distributed on around clamping plate 2 and the die 3, and the screw number is no less than 6, and fluted 6 on the die 3, groove 6 sizes and shape are by battery sizes that is designed and shape decision; Groove 6 positions are in the upper left corner of die 3, groove 6 sides and below reserve the space of 1 ~ 1.2 times of groove area size respectively, screw 5 bore edges and groove 6 Edge Distance l are not less than 10mm; Clamping plate 2 are positioned on the die 3, and appearance and size is identical with die 3, have on it and the identical groove of die 3 upper grooves, 6 shapes, and punch 1 matches with die 3 inner groovies 6 shapes, and punch 1 passes the groove of clamping plate 2; Between the part side of punch 1 insertion clamping plate 2 and the groove medial surface of clamping plate 2 0.1 ~ 0.5mm gap is arranged, fixing by back, alignment pin 4 location earlier between clamping plate 2 and the die 3.
The groove rounded at the edge radius R of said clamping plate 2
1Between 0.5 ~ 2.5mm.
The recess edge radius of corner R of said die 3
2Between 1.5 ~ 3.5mm, and more bigger than said clamping plate groove rounded at the edge radius; Between the groove medial surface of die 3 and the lateral surface of punch 1 0.5 ~ 2mm gap is arranged.
Other radiuss of corner r on said punch 1, clamping plate 2 and the die 3 is between 1 ~ 3mm.
Groove 6 side surfaces of said punch 1 lateral surface and lower surface, said clamping plate 2 groove inner surfaces and die 3 and surface roughness Ra < the 2 μ m of lower surface; Clamping plate 2 bottom surfaces and die 3 end face surface roughness Ra < 9 μ m.
Aluminum-plastic composite membrane is placed between clamping plate 2 and the die 3, and the use alignment pin is tightened screw 5 behind 4 location.Punch 1 is inserted the through hole of pressing plate 2, use press to give punch 3 certain propulsive force, make punch slowly be pressed into die, slowly take out punch 1 after static a period of time.Whole punch steps is accomplished.Take off screw 5, alignment pin 4 and pressing plate 2, can obtain the aluminum-plastic composite membrane groove of corresponding size and shape.
Guarantee that at first die surface is definitely clean before the aluminum plastic film punching press, especially at the groove inwall of die; When the aluminum plastic film gone out uses, at first electric core is put into pit, electrode direction should be towards upside (or left side), downside (or right side) aluminum plastic film is rolled covered on electric core, gets final product fluid injection around sealing and after reserving liquid injection port.The aluminum plastic film pocket on right side (or downside) holds the gas that produces in the formation process as air bag.
The utility model material therefor can be selected stainless steel, aluminium alloy, cast iron etc. for use; The stainless steel effect is best by contrast, corrosion-resistant and long service life, and stainless in addition weight can compress aluminum plastic film; Prevent that aluminum plastic film is out of shape in punching course; In use possibly have the part corrosion, therefore use the back to smear one deck lubricating oil, anti-oxidation on its surface; Aluminum alloy materials is easy to processing and light weight, but possibly cause compaction die power not enough, aluminum plastic film distortion, fold between the trip bolt, and influence is used and is attractive in appearance; Cast iron is comparatively cheap, and weight can reach the fixedly purpose of aluminum plastic film, but its resistance to corrosion is not good, can prevent corrosion in its surperficial coating lubricating oil after use.
