Abstract
The utility model discloses a battery device that freezes, including be equipped with the die cavity just, the negative norm, just, be equipped with the layering between the negative norm, the upper and lower side of layering with the inboard of the tangent department of die cavity is equipped with the recess that one row of interval set up, the recess is seted up the back of layering, on the layering on the inboard groove range layering of side the side the distance with under the layering under the inboard groove range layering of side the distance of side be 2 -3mm. The utility model discloses simple structure, the recess is established with contact department of die cavity to the layering, has reduced the quality that the layering is close to this one side of utmost point ear to reduced the specific heat capacity of this department, the emergence of rosin joint phenomenon can be avoided to the speed that heaies up when having accelerated to freeze, has improved freeze quality and production efficiency.
Description
technical field:
The utility model relates to storage battery production and manufactures field, is specifically related to a kind of storage battery welding device.
background technology:
Polar-group welding operation in battery manufacture process first pole group is contained on comb mould, then beats press strip and make it compress between positive and negative mould then to freeze.Wherein, press strip is positioned in the middle of positive negative bus, the both sides of press strip are close to the edge of positive and negative lug, not reserved welding surplus, and this side specific heat capacity being close to press strip is large, heats up slower, the lug of this side is caused to be difficult to grill thoroughly, easily rosin joint occur, need the later stage to re-start and reprocess repair welding, waste time and energy, greatly affect production efficiency.
summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of storage battery welding device, avoids the generation of rosin joint phenomenon, ensure that the quality of product while enhancing productivity.
The utility model is achieved through the following technical solutions:
A kind of storage battery welding device, comprise the positive and negative mould being provided with die cavity, press strip is provided with between described positive and negative mould, the upper and lower side of described press strip and the inner side at the tangent place of described die cavity are provided with the spaced groove of a row, described groove is opened in the back side of described press strip, and the distance of the groove distance press strip lower side inside press strip lower side described in the Distance geometry of the groove distance press strip upper side edge inside described press strip upper side edge is 2-3mm.
The further improvement project of the utility model is, interval 0.5-1mm between groove adjacent in each row's groove.
The further improvement project of the utility model is, described groove ovalize.
The further improvement project of the utility model is, the bottom land of described groove is apart from the upper plane 2-3mm of described press strip.
Compared to the prior art the utility model has the following advantages:
The utility model structure is simple, and groove is established in the contact position of press strip and die cavity, reduces the quality of press strip near this side of lug, thus reduce the specific heat capacity at this place, accelerate the speed heated up when freezing, the generation of rosin joint phenomenon can be avoided, improve freeze quality and production efficiency.
Accompanying drawing explanation
Fig. 1 is that the utility model overlooks partial schematic sectional view.
Fig. 2 is that the utility model master looks partial schematic sectional view.
Detailed description of the invention
A kind of storage battery welding device as shown in Figure 1, 2, comprise the positive and negative mould 1,2 being provided with die cavity 3, press strip 4 is provided with between positive and negative mould 1,2, the upper and lower side of press strip 4 and the inner side at the tangent place of described die cavity 3 are provided with the spaced groove 5 of a row, alleviate the quality of the press strip of weld, thus reduce specific heat capacity.Groove 5 is opened in the back side of press strip 4, and when preventing from freezing, plumbous liquid flows in groove and blocks groove 5.Groove 5 inside press strip 4 upper side edge apart from press strip 4 upper side edge Distance geometry described in groove 5 inside press strip 4 lower side be 2-3mm apart from the distance of press strip 4 lower side.
In the present embodiment, interval 0.5-1mm between groove 5 adjacent in each row's groove 5, groove 5 is arranged with the teeth groove one_to_one corresponding on positive negative norm.Groove 5 ovalize, the bottom land of groove 5 is apart from the upper plane 2-3mm of described press strip 4.
