Abstract

The utility model discloses a processing equipment of O type reinforcement steel sheet relates to flexible circuit board processing technology field, include: go up mould and lower mould, it is equipped with the upper die spring mechanism and the last edge of a knife to go up the mould, the lower mould is equipped with the lower mould spring mechanism and the lower edge of a knife, upper die spring mechanism with lower mould spring mechanism is just corresponding, it is used for die -cut product excircle to go up the edge of a knife, the edge of a knife is used for the interior circle of die -cut product down, it is greater than to go up edge of a knife diameter the coincidence of edge of a knife diameter, and axle center down, the edge of a knife can insert in the edge of a knife down.

Description

The processing units of a kind of O type reinforcement steel disc

Technical field

The utility model relates to flexible PCB processing technique field, in particular to the processing units of a kind of O type reinforcement steel disc.

Background technology

In recent years, along with the development of automotive electronics part and digital electric part, Sheet Metal Forming Technology has become modern technique, therefore how to improve the production efficiency of making punching press making, reduces costs the problem becoming each manufacturer and must studying. Prior art in the main technique making the minimum O type punching press part product of size is: by production sharing two step punching press, first punching press interior shape, then by the fixing rear punching press profile of the 2nd mold. Owing to this operation carries out two step punching presses, at cost with consume a large amount of time on the time, and precision declines to some extent after two times are located punching press. Production efficiency and quality are all difficult to meet requirement.

Summary of the invention

The technical problems to be solved in the utility model is: reduce the operation making O type punching press part, it is to increase production efficiency and quality.

For solving the problems of the technologies described above, the utility model provides the processing units of a kind of O type reinforcement steel disc, comprising: upper die and lower die, and described patrix is provided with patrix spring device and the upper edge of a knife, and described counterdie is provided with counterdie spring device and the lower edge of a knife; Described patrix spring device is just corresponding with described counterdie spring device; The described upper edge of a knife is used for punching products cylindrical, and the described lower edge of a knife is used for punching products inner circle, and described upper edge of a knife diameter is greater than described lower edge of a knife diameter, and axis coinciding, and the described lower edge of a knife can insert in the edge of a knife.

Preferably, also comprise: binder axle, by transmitting low mucous membrane by the product rolling of forming.

The processing units of this O type reinforcement steel disc is by the upper edge of a knife that cooperatively interacts and the lower edge of a knife, it is possible to disposable circle product external and inner circle are punched out, and avoids the problem being produced inefficiency and the positioning precision difference caused by twice operation.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the processing units of O type reinforcement steel disc of the present utility model.

Fig. 2 is the vertical view of the processing units of the O type reinforcement steel disc in Fig. 1.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail. Following examples are for illustration of the utility model, but are not used for limiting scope of the present utility model.

Processing units as depicted in figs. 1 and 2, comprising: patrix 2 and counterdie 3, and patrix 1 is provided with patrix spring device 5 and the upper edge of a knife 6, and counterdie 2 is provided with counterdie spring device 4 and the lower edge of a knife 3. Patrix spring device 5 is positive corresponding with counterdie spring device 4.

The upper edge of a knife 6 is for punching products cylindrical, and the lower edge of a knife 3 is greater than the lower edge of a knife 3 diameter for punching products inner circle, the upper edge of a knife 6 diameter, and axis coinciding, and the lower edge of a knife 3 can insert in the edge of a knife 6.

In order to be arranged according to rule by the finished product of forming, this processing units also comprises: binder axle 7, by transmitting low mucous membrane by the product rolling of forming.

Concrete production stage comprises:

Step one, steel band 1 are sent to processing units by transfer roller;

Step 2, patrix 2 decline, and patrix spring device 5 and the upper edge of a knife 6 stretch out, and counterdie spring device 4 and the lower edge of a knife 3 shrink, and patrix 2 and counterdie 3 collide, and steel plate 1 is punched out circle product external by the upper edge of a knife 6;

Step 3, counterdie spring device 4 and the lower edge of a knife 3 rebound, the die-cut steel plate 1 of the lower edge of a knife 3, form product inner circle;

Step 4, binder axle 7 carry low mucous membrane 8, and product 9 drops on low mucous membrane 8, by one-tenth row's rolling.

Mode of more than implementing is only for illustration of the utility model; and be not limitation of the utility model; about the those of ordinary skill of technical field; when not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
