Lithium battery is that a class is negative material, the battery that uses non-aqueous electrolytic solution by lithium metal or lithium alloy.It is a kind of device that chemical energy is directly changed into electric energy, its operation principle: when charging, utilizing outside electric energy to make inner active material regeneration, is chemical energy electrical power storage, need to discharge time, again chemical energy is converted to electric energy output.
In Production Process of Lithium Battery, on lithium battery case, can process slot rolling, reduce the internal diameter of lithium battery case with this part, thereby lay lithium battery cap.Slot rolling plays position-limiting action to block.In prior art, the mould of processing slot rolling comprises and rolls core and roll sleeve, and roll sleeve is inserted in and rolls in core, and the one end of rolling core exceeds the end face of roll sleeve, with this, lithium battery case positioned.When work, mould is clamped by chuck, lithium battery case is promoted by cylinder, roll that core exceeds the part of roll sleeve end face and the inwall of lithium battery case coordinates, carry out spacingly, simultaneously lithium battery case openend and roll sleeve end contact are fixed lithium battery case, and then lithium battery case is with all rotations of chuck, process tool feed, completes the processing of slot rolling.The drawback of this scheme is in the time of feed, and lithium battery case can be subject to larger power, and mould does not limit lithium battery case outer wall, can cause the external diameter distortion of lithium battery case top, become large, becomes and exceedes 0.15mm on a large scale, has affected the quality of lithium battery case.
Utility model content
The utility model is for the problems referred to above, proposed a kind ofly for processing the mould of lithium battery case slot rolling, and for solving lithium battery case when the processing feed, lithium battery case top external diameter becomes large problem.
The technical scheme that the utility model is taked is as follows:
A kind of for processing the mould of lithium battery case slot rolling, comprise roll sleeve and be slidably mounted on the core that rolls in roll sleeve, roll sleeve one end opening, the other end is provided with jack, describedly roll that end that core contacts with lithium battery case for rolling core working end, the inwall of described roll sleeve open end and roll between the outer wall of core and there is the gap for holding lithium battery case.
As preferably, described in roll core vicinity and roll core working end place and be provided with the first bucking ladder, in described roll sleeve, be provided with thrust spring, described thrust spring is set on the outer wall that rolls core, two ends are butt roll sleeve and the first bucking ladder respectively.
As preferably, described the first bucking ladder and roll between core working end and be provided with limiting stand, is provided with the brake platform cooperatively interacting with limiting stand in described roll sleeve.Limiting stand and brake platform cooperatively interact, and head into the distance of mould for limiting the compacted cylinder of lithium battery case.
As preferably, described in roll that end that core passes jack and be provided with anticreep locknut.Anticreep locknut can prevent from rolling core and eject roll sleeve.
As preferably, described in roll core and there is a undergauge section matching with lithium battery case inwall away from that end of jack.Undergauge section and lithium battery case inwall cooperatively interact, and can guarantee that lithium battery case top internal diameter is not more big changes in the time of processing slot rolling.
As preferably, that end that described undergauge section deviates from jack is provided with a guiding lithium battery case and is inserted in the guiding step that rolls core.Guiding step can guide lithium battery case better with roll core and coordinate, prevent from misplacing etc., make to process convenient.
As preferably, described in roll the end face that core leans with lithium battery case diameter equate with lithium battery external diameter.When lithium battery case enters roll sleeve, roll sleeve can better limit lithium battery case top, better prevents distortion.
As preferably, described gap is between undergauge section outer wall and roll sleeve inwall.What the distance between undergauge section outer wall and roll sleeve inwall held is the top of lithium battery case, can farthest limit like this lithium battery case top, Reducing distortion.
The beneficial effects of the utility model are: lithium battery case can be held by the gap between undergauge section outer wall and roll sleeve inwall, make in the time of processing slot rolling, roll sleeve can limit lithium battery case top outer wall cover, guarantees that lithium battery case top external diameter does not have larger distortion.
