Description
Technical field
The utility model belongs to Design of Dies field, relates to bus-bar, and especially a kind of bus-bar pre-bends molding structure.
Background technology
Bus-bar normally integrally makes two row's tuning forks in host conductive sheet both sides, and two row's tuning forks need to carry out 90 ° of bendings downwards, the bending chamfering part A of Fig. 1 (in see the accompanying drawing) is formed at conducting strip and tuning fork junction, this bending process is normally formed by mould punching, normally a pair jacking block Reference numeral 2 and 5 of Fig. 2 (in see the accompanying drawing) is set at convex template and the upper and lower correspondence of concave template, for positioning compression bus-bar conducting strip position, jacking block both sides on convex template arrange drift (Reference numeral 3 see Fig. 2 in accompanying drawing) respectively, each drift is corresponding with the tuning fork of conducting strip both sides, the gap Reference numeral 4 of Fig. 2 (in see the accompanying drawing) is left between each drift and jacking block, this gap is as the chamfer design of tuning fork downward bending, after punching press, die sinking, after drift climbs away workpiece, jacking block on punch rises and leaves workpiece, complete a bending, after bending, bus-bar is stayed on the jacking block on die, by hand bus-bar is taken off from concave template.
But there is following two problems in this bending process:
When using above-mentioned bending and molding structure bending due to the jacking block on punch first workpiece is pushed down after carry out bending again, so mid portion is more smooth, but it is comparatively large once to roll over 90 ° of workpiece resiliences, and angle correction is more difficult, is difficult to control;
During bending, bending angle interior angle pressurized, exterior angle Tensile.Due to one time, bending angle is too large, and bending exterior angle deformed in tension is maximum, causes the workpiece of surface band coating to have by the phenomenon of drawing crack at bending exterior angle place, can take the lead in herein aging when bus-bar uses, more easily fracture herein, cause open circuit, cause the accident.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of workpiece of avoiding to be pre-bended molding structure by the bus-bar of drawing crack.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of bus-bar pre-bends molding structure, comprise briquetting, beveled punch and inclined-plane jacking block, described briquetting, beveled punch are arranged on the lower surface of convex template downwards, the concave template corresponding with briquetting is provided with inclined-plane jacking block, level in this inclined-plane jacking block and both sides are 45 ° of Caused by Sloping Surfaces, it is beveled punch domatic on 45 ° that the convex template of briquetting both sides corresponding to 45 ° of Caused by Sloping Surfaces with both sides is provided with bottom surface.
And the upper domatic of beveled punch of both sides matches with the Caused by Sloping Surfaces of jacking block both sides, inclined-plane respectively.
Advantage of the present utility model and good effect are:
The bus-bar that the utility model the provides molding structure that pre-bends is first by workpiece bending 45 °, and then rolls over 90 °, and realize workpiece thus and roll over 45 ° at every turn, workpiece springback capacity is little, and bending angle more easily controls; Bending angle is little, and bending exterior angle deflection is little, and surface of the work tin layers is not easily by drawing crack, and during second time bending, bending point is different from first time, and can not cause succeeding stretch, so after second time bending, bending exterior angle place also there will not be tin layers drawing crack phenomenon.
The bus-bar bending relaying former that the utility model provides reduces the difficulty revising bending angle, thus reduce die debugging cost, solve the easy drawing crack problem of bending exterior angle workpiece tin layers simultaneously, add the ageing resistance of product, improve the safety in utilization of product.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of bus-bar pre-bends molding structure, see Fig. 3, comprise briquetting 6, beveled punch 7 and inclined-plane jacking block 10, described briquetting, beveled punch are arranged on the lower surface of convex template downwards, the concave template corresponding with briquetting is provided with inclined-plane jacking block, level in this inclined-plane jacking block and both sides are 45 ° of Caused by Sloping Surfaces 9, it is beveled punch 8 domatic on 45 ° that the convex template of briquetting both sides corresponding to 45 ° of Caused by Sloping Surfaces with both sides is provided with bottom surface, and the upper domatic of beveled punch of both sides matches with the Caused by Sloping Surfaces of jacking block both sides, inclined-plane respectively.
Operation principle of the present utility model is:
See Fig. 3, workpiece 1 is between briquetting and inclined-plane jacking block, for positioning compression bus-bar conducting strip position, the Caused by Sloping Surfaces of each beveled punch and the Caused by Sloping Surfaces of jacking block both sides, inclined-plane are corresponding with the upper surface of the tuning fork of conducting strip both sides and lower surface respectively, during punching press, formation tuning fork and conducting strip are 45 ° of bendings, after punching press, die sinking, after drift climbs away workpiece, briquetting on punch rises and leaves workpiece, complete relaying bending, after bending, bus-bar is stayed on the inclined-plane jacking block on die, is taken off by bus-bar by hand from concave template.
After taking off, see Fig. 4, by 45 ° of bendings that an original bending and molding structure is carried out in the same way to bus-bar again, this bending and molding structure arranges a pair jacking block 2 and 5 at convex template and the upper and lower correspondence of concave template, for positioning compression bus-bar conducting strip position, jacking block both sides on convex template arrange drift 3 respectively, each drift is corresponding with the tuning fork of conducting strip both sides, gap 4 is left between each drift and jacking block, this gap is as the chamfer design of tuning fork downward bending, after punching press, die sinking, after drift climbs away workpiece, jacking block on punch rises and leaves workpiece, shaping by twice thus, achieve 90 ° of bendings, finished product after bending as shown in Figure 1.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
