Detailed description of the invention
Below in conjunction with drawings and embodiments, the utility model is described in detail.
The utility model provides die cutting die, and it is suitable and then to the die 1 of the battery pole piece of die-cut formation lithium battery and punch 2 that this die cutting die comprises shape, structure, size.Wherein, die 1 at least comprises two splices, and each splice successively head and the tail encloses this die 1 separably, and when enclosing die 1, suitably the position of each splice of adjustment can realize the adjustment of shape, size.
In a detailed description of the invention, splice comprises splice 11, lower splice 12, left splice 13 and right splice 14, and left splice 13, upper splice 11, right splice 14 and lower splice 12 head and the tail abut against separably successively and then enclose this die 1.By arranging this four splices 11 ~ 14, can realize easily position on four direction up and down separately or adjusted in concert, make the adjustment of the shape and size of die 1 more flexible, adaptability is stronger.Certainly, the splice of other quantity can also be arranged to, not enumerate herein.In addition, size, the structure of each splice can be set to identical or different, and usually, because the product of required making is as the reason of this body structure of battery pole piece, the size of each splice is different with structure.
In a detailed description of the invention, die 1 also comprises the position adjustments part 15 identical with splice quantity, and each position adjustments part 15 is corresponding can be dynamically connected independently regulate splice to advance or retreat with a splice.Advance by regulating splice and can reduce the size of die 1, and by regulating splice to retreat the size that can increase die 1.
Specifically, this position adjustments part 15 comprises fixed head 151 and at least one screw 152, screw 152 one end is sheathed on fixed head 151, the other end screws in corresponding splice, by rotating forward or reversely rotate screw 152 at fixed head 151 place, make splice in opposite directions fixed head 151 move (away from) or deviate from fixed head 151 and move (retrogressing) and realize fine position.Further, screw 152 quantity is two, and one end of each screw 152 is sheathed on fixed head 151 respectively, the other end screws in corresponding splice.Wherein, fixed head 151 is provided with through adjusting hole 1510, adjusting hole 1510 is divided into two sections, one section size is large, one section of size is little, large one section allows the screw rod of screw 152 and nut to enter, little one section only allows the screw rod of screw 152 to enter, the end that screw 152 one end (i.e. screw rod) screws in splice through adjusting hole 1510, the other end (i.e. nut) is limited at the contiguous splice side of adjusting hole 1510.
In above-mentioned embodiment, the interior shape of the die 1 that splice encloses jointly is identical with the shape of the battery pole piece with lug; Splice is also provided with through hole (not shown) to be lock onto in support member (not shown) by splice by screw 16.
In a detailed description of the invention, the surface that punch 2 is opposite in die 1 is provided with multiple vacuum hole 20, and this vacuum hole 20 provides secured via vacuum battery pole piece, ensures that die cutting accuracy is higher.
Further, die cutting die can also comprise punch position adjustments part 3, punch position adjustments part 3 comprises fixed head 31 and at least one screw 32, screw 32 one end is sheathed on fixed head 31, the other end screws in punch 2, by rotating forward or reversely rotate screw 32 at fixed head 31 place, can make punch 2 in opposite directions fixed head 31 move or deviate from fixed head 31 and move and realize fine position.This punch position adjustments part 3 is substantially identical with principle with position adjustments part 15 structure of die 1, refers to above, does not do repeated description herein.By arranging punch position adjustments part 3, can how a kind of mode adjusting gap between die 1 and punch 2, the position of punch 2 namely only need be adjusted in some scenes, more simple and convenient.
The operation principle of the die cutting die of the utility model embodiment is specific as follows.
1. die 1 makes---by providing battery pole piece dimension analysis to client, die 11 ~ 14 part is as shown in Figure 2 become (namely to go up splice 11, lower splice 12, left splice 13 and right splice 14 4 splices its battery pole piece sized divisions, also other form can be divided into), then after carrying out a series of machining, complete the making of die 11 ~ 14 part.
Assembling---die 11 ~ 14 part made is installed by Fig. 2 position under digital microscope, and permanent order for before this die 11 ~ 14 position was put well, then pre-fixes die 11 ~ 14 by 8 screws 152; Wherein, fixed head 151 is fixing, screw 152 is enclosed within fixed head 151, in other end precession die 11 ~ 14, needing can with inner hexagon spanner by adjusting hole 1510 rotary screw 152 when adjusting, screw 152 will drive die 11 ~ 14 to advance or retreat to reach fine setting object, fastening 8 screws 152 again after confirmation; Punch 2 screw 32 is fixed on fixed head 31.
die-cut confirmation---by the vacuum that the punch 2 after above assembling confirms is provided by vacuum hole 20, battery pole piece is held, punch 2 and die 1 carry out die-cut to battery pole piece under the guiding of guide pillar, confirm whether dry linting and burr meet the requirements, if do not meet both confirmations gap whether to meet the requirements, then with digital microscope, difference measured.
repair a die--problematic die 11 ~ 14 part is pulled down, by the difference after measuring, it is revised, after confirmation, repeat second and third step action above again.
The die-cut die 1 of the utility model embodiment and die cutting die thereof: enclose die 1 by adopting at least two splices, die 1 is made itself to have architectural characteristic adjustable flexibly, the parameter such as shape, size of die 1 can be finely tuned according to actual conditions, gap between die 1 and punch 2 can freely be adjusted, die 1 can not be scrapped because of size reason, when die-cut making battery pole piece, its precision is higher, dry linting or large burr can not be produced, be not easy to cause waste of material, saved manufacturing cost.
These are only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
