Abstract
Description
Technical field
The utility model relates to a kind of battery machined tool, especially battery component processing mold, belongs to battery and field of mechanical technique.
Background technology
At present, the pole piece production of rectangular cell is generally first the lug punching molding, lug and pole piece roll welding is integral again, and then carries out laminated combination, with bolt or rivet pole piece group and pole is linked together.After the punching of lug elder generation, when stack of laminations merges with bolt fixedly, cause the mutual changing of the relative positions of pole piece because the deformation extent of lug part is different, make the pole plate group not concordant, and also cause the overall height dimension error larger.The method is because of the variable thickness of lug and pole piece, and when being connected, lug part deformation extent differs, and it is inconsistent that pole plate is staggered each other, and one makes outward appearance irregular, and height error increases; Two have also increased the chance of micro-short circuit between pole piece.
The utility model content
For the problems referred to above, the utility model provides a kind of lug processing mold.
The technical scheme that its technical problem that solves the utility model adopts is: the battery pole ear punching trims mould, comprises lower bolster, cope match-plate pattern and top board; Cope match-plate pattern is connected positioning guide column and is connected with top board; The lower bolster relevant position is provided with the guide pillar groove; The lower surface of top board be provided with run through cope match-plate pattern and lower bolster trim blade and punching needle; Be provided with pre-compressed spring between cope match-plate pattern and the lower bolster; The upper surface of top board is provided with chuck.
The beneficial effects of the utility model are, and are simple in structure, easy to use; Can guarantee consistency from top to bottom between pole piece, the pole plate group is concordant, and the overall height dimension error is little, has avoided the generation of micro-short circuit phenomenon between pole piece.Solve the every a slice lug of battery pole plates group assembling process demand length dimension length size inconsistence problems; Also solve in the past lug and unify the superimposed irregular problem of pole piece that processing dimension is brought, and the problem of not playing well because of pole plate dislocation battery capacity.Being mainly used in shaping, punching and lug top that pole piece makes up the lug part of later half pole plate group trims.
Description of drawings
Fig. 1 is the utility model general structure schematic diagram;
Parts and numbering among the figure:
1-lower bolster, 2-cope match-plate pattern, 3-top board, 4-positioning guide column, 5-guide pillar groove,
6-trim blade, 7-punching needle, 8-pre-compressed spring, 9-chuck, 10-spacing pin.
The specific embodiment
Below in conjunction with embodiment the utility model is further specified.
Referring to Fig. 1, the battery pole ear punching trims mould, comprises lower bolster 1, cope match-plate pattern 2 and top board 3; Cope match-plate pattern 2 is connected with top board by positioning guide column 4 connections; Lower bolster 1 relevant position is provided with guide pillar groove 5; The lower surface of top board 3 be provided with run through cope match-plate pattern 2 and lower bolster 1 trim blade 6 and punching needle 7; Be provided with pre-compressed spring 8 between cope match-plate pattern 2 and the lower bolster 1; The upper surface of top board 3 is provided with chuck 9.
Lower bolster 1 is provided with spacing pin 10.
The punching operation in the connecting bolt hole of lug is adjusted to after the lamination operation by pole piece punching out operation, carry out again the pole piece group lug shaping, punching and with after the shaping mutually not concordant lug top cut.Adopt plastics design at punching die, the lug head of pole plate group is gone in advance again arrive real use state first, again it is carried out punching, and the lug top of causing because of shaping was trimmed in uneven whole minute.Make under the constant prerequisite of pole plate group height, guaranteed the consistency from top to bottom between pole piece.
After half pole plate group is clamped by fixture, manual lug with the pole plate group partly stretches in the mould and by baffle plate locates, punch press is by chuck 9, the drive top mold frame is descending, cope match-plate pattern 2 and lower bolster 1 pressing, forming face by lower bolster 1 is out of shape shaping to the lug position, for guaranteeing the stress equalization of mould bases, by the downstream position of spacing pin 10 restriction cope match-plate patterns 2.After the lug shaping is finished, stop descending behind the spacing pin 10 of cope match-plate pattern 2 contacts this moment, top mold frame continues to press down, pre-compressed spring 8 is compressed, this moment, punching needle 7 and trim blade 6 and pass from the pilot hole of cope match-plate pattern 2 carried out punching with the lug position, and because to trim the Length Ratio punching needle 7 of blade 6 slightly short, after spacing to the punching of lug part, trim blade 6 and also the lug top is trimmed.
Lug shaping, punching, lug top partly by half pole plate group trims, after having avoided the punching of lug elder generation, when stack of laminations merges with bolt fixedly, cause the mutual changing of the relative positions of pole piece because the deformation extent of lug part is different, make the pole plate group not concordant, and also cause the overall height dimension error larger.
