The utility model discloses a kind of FPC blanking dies for improving punching and producing tear, it includes the stub end blanking die being adapted with FPC stub end shapes, the small head end blanking die being adapted with the small head end shapes of FPC, the overall blanking die being adapted with FPC monnolithic cases, stub end blanking die, small head end blanking die are located at the front that material strip enters mould direction, and overall blanking die is located at the rear end side that material strip enters mould direction；Stub end blanking die, small head end blanking die are in bathtub construction respectively, and the flute profile width of stub end blanking die is small compared with the width value of the stiffening plate of FPC stub ends, and the flute profile width of small head end blanking die is small compared with the width value of the stiffening plate of the small head ends of FPC.On the one hand the quality that cuts of FPC finger positions can be effectively ensured in the utility model, on the other hand can effectively avoid tearing phenomenon, and then can effectively reduce the defective products caused by tear, you can effective Improving The Quality of Products simultaneously improves enterprise competitiveness.

Description

A kind of FPC blanking dies for improving punching and producing tear

Technical field

FPC technical fields are the utility model is related to, more particularly to a kind of FPC blanking dies for improving punching and producing tear Tool.

Background technology

As a kind of circuit board structure, FPC（FPC）It is widely used in various electronic products, such as hand Machine, tablet personal computer etc..Wherein, for FPC, it is generally required by lamination reinforcement plate to strengthen its intensity.

During FPC is cut, FPC plug finger end is easy to occur stiffening plate and FPC tangency location tear Phenomenon, and then cause defective products rate to improve, also increased entreprise cost.

Utility model content

The purpose of this utility model is to provide a kind of improve in view of the shortcomings of the prior art and be punched generation tear FPC blanking dies, this can improve punching and produce the FPC design of stamping die novelty of tear and can be effectively prevented from tearing phenomenon Occur, and then the defective products caused by tear can be efficiently reduced, you can effectively Improving The Quality of Products and to improve enterprise competing Strive power.

To reach above-mentioned purpose, the utility model is achieved through the following technical solutions.

A kind of FPC blanking dies for improving punching and producing tear, include the major part being adapted with FPC stub end shapes End blanking die, the small head end blanking die being adapted with the small head end shapes of FPC, the overall punching being adapted with FPC monnolithic cases Mould is cut out, stub end blanking die, small head end blanking die are located at the front that material strip enters mould direction, and overall blanking die is located at Material strip enters the rear end side in mould direction；

Stub end blanking die, small head end blanking die are in bathtub construction respectively, the flute profile width of stub end blanking die Width value compared with the stiffening plate of FPC stub ends is small, the width of the flute profile width of small head end blanking die compared with the stiffening plate of the small head ends of FPC Angle value is small.

The beneficial effects of the utility model are：A kind of FPC punchings for improving punching and producing tear described in the utility model Cut out mould, it includes the stub end blanking die being adapted with FPC stub end shapes, is adapted with the small head end shapes of FPC Small head end blanking die, the overall blanking die being adapted with FPC monnolithic cases, stub end blanking die, small head end blanking die Tool enters the front in mould direction positioned at material strip, and overall blanking die is located at the rear end side that material strip enters mould direction；Stub end blanking die Tool, small head end blanking die are in bathtub construction respectively, and the flute profile width of stub end blanking die is compared with the stiffening plate of FPC stub ends Width value is small, and the flute profile width of small head end blanking die is small compared with the width value of the stiffening plate of the small head ends of FPC.Set by said structure On the one hand meter, the utility model can effectively ensure the quality that cuts of FPC finger positions, on the other hand can be effectively prevented from Phenomenon is torn, and then the defective products caused by tear can be efficiently reduced, you can effectively Improving The Quality of Products and is carried High enterprise competitiveness.

Brief description of the drawings

The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing is not formed pair Any restrictions of the present utility model.

Fig. 1 is structural representation of the present utility model.

Include in Fig. 1：

1 --- stub end blanking die

2 --- small head end blanking die

3 --- overall blanking die.

Embodiment

The utility model is illustrated with reference to specific embodiment.

As shown in figure 1, a kind of FPC blanking dies for improving punching and producing tear, include and FPC stub end shape phases The stub end blanking die 1 of adaptation, the small head end blanking die 2 being adapted with the small head end shapes of FPC and FPC monnolithic case phases The overall blanking die 3 of adaptation, stub end blanking die 1, small head end blanking die 2 are located at the front that material strip enters mould direction, Overall blanking die 3 is located at the rear end side that material strip enters mould direction.

Wherein, stub end blanking die 1, small head end blanking die 2 are in bathtub construction respectively, stub end blanking die 1 Flute profile width is small compared with the width value of the stiffening plate of FPC stub ends, and the flute profile width of small head end blanking die 2 is compared with the small head ends of FPC The width value of stiffening plate is small.

Because FPC product finger ends are with the presence of PI reinforcement differences in height, and mould only simultaneously has clip, is preferentially ensureing finger First using stub end blanking die 1, the corresponding stub ends of lower head end blanking die punch press process FPC, lower end in the case of quality Head；Because the flute profile width of stub end blanking die 1 is small compared with the width value of the stiffening plate of FPC stub ends, small head end blanking die 2 Flute profile width it is small compared with the width value of the stiffening plate of the small head ends of FPC, the stub end blanking die 1 of the structure design, the punching of small head end Cutting out mould 2 can be effectively prevented from contacting stiffening plate and FPC tangency location during punching, and then avoid being punched FPC finger positions When there is the problem of stiffening plate and FPC tangency locations are torn.Treat that stub end blanking die 1, small head end blanking die 2 are cut After, carry out cutting action by overall blanking die 3, wherein, overall blanking die 3 first cuts away PI reinforcement to be switched to again FPC, be not in thus that reinforcement has tear phenomenon with the tangent positions of FPC, can thoroughly solve bad problem caused by tear.

From the above situation, it can be seen that, on the one hand FPC hands can effectively be ensured by said structure design, the utility model Refer to position cuts quality, on the other hand can be effectively prevented from tearing phenomenon, and then can efficiently reduce because of tear Caused defective products, you can effectively Improving The Quality of Products and improve enterprise competitiveness.

Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications To limitation of the present utility model.
