Description
Technical field
The present invention relates to a kind of power battery post body processing technology, power battery electrode cylinder prepared by this processing technique is applicable to lithium ion battery, Ni-MH battery, nickel-cadmium cell, nickel carbon battery and other secondary cells。
Background technology
At present, the riveting process that Vehicular dynamic battery pole body particularly lithium ion battery adopts, riveting process can only guarantee that the connection between two different parts is the mode by physical connection, it is not an entirety, life-time service would be likely to occur the thermal coefficient of expansion between due to material inconsistent cause riveted joint generation gap, position, simultaneously it is also possible to position produces oxide-film because heating or other reasons cause riveted joint, cause that connecting internal resistance increases, additionally, pole body complex manufacturing technology in the past, spillage of material is big。
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of power battery post body processing technology, self internal resistance of the power battery electrode cylinder that it is prepared is smaller, and simplifies technique, reduces spillage of material。
In order to solve above-mentioned technical problem, the technical scheme is that a kind of power battery post body processing technology, comprise following step:
(1) bus-bar molding；
(2) seal disc pole processing；
(3) bus-bar welds with the seal disc of seal disc pole；
(4) bus-bar fluting, forms multiple sheet that confluxes, and the adjacent sheet that confluxes has interval trough；
(5) conflux the porch chamfering of sheet；
(6) conflux the arris place chamfering of bottom of sheet；
(7) Nickel Plating Treatment。
Further, in described step (1), bus-bar is by punch forming or moulding by casting。
Further, in described step (3), what bus-bar welded employing with the seal disc of seal disc pole is high-frequency welding manner。
Further, the weld of bus-bar and seal disc pole has the welding degree of depth of 0.1～100mm。
Further, bus-bar and/or seal disc pole are made up of rustless steel or pure iron or aluminum or copper product。
Further, in described step (4), the width of described interval trough is 0.1～10mm。
Further, the porch of the described sheet that confluxes and the chamfer angle of bottom are 1～89 °。
Further, in described step (4), the thickness of the described sheet that confluxes is 0.1～50mm。
Further, machining and carry out plating nickel on surface process afterwards, nickel plating adopts chemical nickel plating or electronickelling。
After have employed technique scheme, chamfer design owing to welding pole body is advantageously implemented mechanical automation assembling, the damage brought to battery pole ear can be prevented effectively from pole body assembling process, realize the connection of seal disc pole and bus-bar and can at utmost reduce in pole body and hinder by welding simultaneously。

Fig. 1 is the schematic flow sheet of the power battery post body processing technology of the present invention；
Fig. 2 is the schematic diagram of the manufacture process of the power battery post body processing technology of the present invention。
Detailed description of the invention
Being clearly understood to make present disclosure be easier to, below according to specific embodiment and in conjunction with accompanying drawing, the present invention is further detailed explanation。
As shown in Figure 1, 2, the power battery post manufacturing method of the present embodiment includes following step:
Step S101, bus-bar molding:
Utilizing mould that material 101 is made the shape of bus-bar semi-finished product 102 as shown in Figure 2, this bus-bar molding is by punch forming or moulding by casting。
Step S102, seal disc pole is processed:
Machining mode is adopted to process seal disc pole semi-finished product 202 as shown in Figure 2 by raw material 201。
Step S103, bus-bar welds with the seal disc of seal disc pole:
Adopt high-frequency welding manner bus-bar semi-finished product 102 and seal disc pole semi-finished product 202 to be welded, form power battery electrode cylinder the first semi-finished product 301；Weld has the welding degree of depth of 0.1～100mm。
Step S104, bus-bar is slotted, and forms power battery electrode cylinder the second semi-finished product 302, and the width of interval trough 12 can be 0.1～10mm, and this width refers to the adjacent spacing confluxing between sheet；The thickness of sheet of confluxing can be 0.1～50mm, and this thickness refers to the sheet thickness in the vertical direction of the width of interval trough that confluxes。
Step S105, sheet 13 entrance chamfering of confluxing, form power battery electrode cylinder the 3rd semi-finished product 303。
Step S106, the arris chamfering of sheet 13 bottom of confluxing, form power battery electrode cylinder the 4th semi-finished product 304。The described porch of the sheet 13 that confluxes and the chamfer angle of bottom are 1～89 °。The chamfer angle of the present embodiment selects 45 °。
Step S107, nickel plating, form power battery electrode cylinder finished product 305, in order to prevent pole body to be in use corroded, pole body entirety is carried out Nickel Plating Treatment, nickel plating can adopt chemical plating, it would however also be possible to employ electronickelling, and the present embodiment adopts chemical nickel plating。
Bus-bar and/or seal disc pole are made up of rustless steel or pure iron or aluminum or copper product, but are not limited to this。
The power battery post body examination of preparation is tried its resistance, relatively low, simultaneously in preparation process, also reduce the loss of material。
Particular embodiments described above; to present invention solves the technical problem that, technical scheme and beneficial effect further described; it is it should be understood that; the foregoing is only specific embodiments of the invention; it is not limited to the present invention; all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention。
