Abstract
The utility model discloses a can firm comb plate mould that welds utmost point ear, its characterized in that: including the comb plate, be equipped with on the comb plate utmost point post constant head tank, with the emissions groove that converges of utmost point post constant head tank intercommunication, the busbar inslot is equipped with a plurality of tooth's socket of pegging graft with the cooperation of utmost point ear, the tooth's socket with the junction adoption circular arc or the chamfer transitional coupling that converge the emissions groove. The utility model discloses simple structure adopts circular arc or chamfer transitional coupling in the tooth's socket and the junction of the emissions groove that converges, and the junction of utmost point ear welding back and busbar bottom is fillet or 45 oblique angle, has avoided the production of junction internal stress, has increased joint strength, can prevent the junction fracture, has improved the welded quality one time, and the number of times has promoted production efficiency thereby greatly reduced does over again.
Description
Technical field
The utility model relates to storage battery production and manufactures field, be specifically related to a kind of can the comb plate die of firm soldering polar ear.
Background technology
Polar-group welding operation in battery manufacture process is first contained on comb plate die by pole group, then beats press strip and make it compress between positive negative norm then to freeze.Its lug of pole group after freezing often can rupture from bus-bar, and need often to do over again, the success rate of once welding is lower, affects production efficiency.Tracing it to its cause be the junction of lug and bus-bar is right angle, and easily produce internal stress, namely this body structure exists the risk of certain fracture.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can the comb plate die of firm soldering polar ear, structure is simple, makes circular arc between lug and bus-bar excessive, increases bonding strength, prevent junction from rupturing.
The utility model is achieved through the following technical solutions:
A kind of can the comb plate die of firm soldering polar ear, it is characterized in that: comprise pecten, the busbar channel that described pecten is provided with pole locating slot, is communicated with pole locating slot, be provided with the some teeth groove coordinating grafting with lug in described busbar channel, described teeth groove adopts circular arc or chamfered transition to be connected with the junction of described busbar channel.
The further improvement project of the utility model is, described teeth groove equidistant intervals is arranged and width is 2-5mm.
The further improvement project of the utility model is, in described arc transition, the radius of circular arc is 0.5-2mm, arc length is 0.5-2mm.
The further improvement project of the utility model is, the chamfering in described chamfered transition is the length 0.5-2mm of 45 ° and chamfering.
The utility model compared with prior art has the following advantages:
The utility model structure is simple, circular arc or chamfered transition is adopted to be connected at teeth groove with the junction of busbar channel, after tab welding with bus-bar bottom junction be the oblique angle of fillet or 45 °, avoid the generation of junction internal stress, add bonding strength, can prevent junction from rupturing, improve the quality of once welding, greatly reduce and do over again number of times thus improve production efficiency.

Detailed description of the invention
As shown in Figure 1,2,3, 4 a kind of can the comb plate die of firm soldering polar ear, comprise pecten 1, the busbar channel 12 that pecten 1 is provided with pole locating slot 11, is communicated with pole locating slot 11, be provided with the some teeth groove 13 coordinating grafting with lug 2 in busbar channel 12, teeth groove 13 adopts circular arc or chamfered transition to be connected with the junction of busbar channel 12.After welding, lug 2 and the junction bottom bus-bar 3 are the oblique angle of fillet or 45 °, can eliminate stress.
In the present embodiment, teeth groove 12 equidistant intervals is arranged and width is 2-5mm.In the arc transition adopting circular arc excessive and described in the present embodiment, the radius of circular arc is 0.5-2mm, arc length is 0.5-2mm.According to chamfered transition, then chamfering is the length 0.5-2mm of 45 ° and chamfering.
