Description

A noise-reducing punching die

technical field

The utility model relates to the technical field of punching dies, in particular to a noise-reducing punching die.

Background technique

In the process of punching the material tape by the punching die, because the material to be punched is thick and the trimming line is relatively long, the punching force will increase during punching, and the punching noise will also increase, which seriously affects the punching effect. Cutting workshop noise environment.

Utility model content

The purpose of the utility model is to provide a noise-reducing punching die for the deficiencies of the prior art. The noise-reducing punching die has a novel design and a simple structure, and effectively reduces punching force and punching noise.

In order to achieve the above object, the utility model is realized through the following technical solutions.

A noise-reducing punching die, comprising a lower mold base and an upper mold base, a lower template is installed on the upper end of the lower mold base, a punching avoidance hole is arranged on the upper end of the lower template, and a pressure plate is installed on the lower end of the upper mold base, And the upper end of the pressing plate is equipped with a vertically arranged punch, and the lower end of the punch is provided with an inclined knife edge, the punch is fixedly installed on the upper end of the upper splint, and the upper splint is arranged on the upper end of the pressing plate.

Wherein, the upper end of the lower mold base is provided with a discharge hole corresponding to the punching avoidance hole.

Wherein, the inclination angle a of the knife edge is 1°-3°.

Wherein, an upper backing plate is installed between the upper splint and the upper mold base.

The beneficial effects of the utility model are: a noise-reducing punching die described in the utility model includes a lower mold base and an upper mold base, the upper end of the lower mold base is equipped with a lower template, and the upper end of the lower template is provided with a punching die The avoidance hole, the lower end of the upper die base is equipped with a pressing plate, and the upper end of the pressing plate is equipped with a vertically arranged punch, and the lower end of the punch is provided with an inclined knife edge, and the punch is fixed on the upper The top of the splint, and the upper splint is arranged on the top of the pressing plate. The utility model is provided with an inclined knife edge at the lower end of the punch, so that the left and right ends of the knife edge are not synchronized when punching the material, thereby reducing the punching force of the punch when punching, and further reducing the punching noise; Therefore, the utility model has the advantages of novel design, simple structure, effectively reduced punching force and punching noise.

Description of drawings

The utility model is further described below using the drawings, but the embodiments in the drawings do not constitute any limitation to the utility model.

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

In Figure 1 are included:

1——Lower mold holder 11——Lower template

111——punching avoidance hole 12——discharging hole

2——upper die base 21——press plate

22——Punch 221——Knife edge

23——upper splint 24——upper backing plate.

Detailed ways

The utility model will be described below in conjunction with specific embodiments.

As shown in Figure 1, a noise-reducing punching die includes a lower mold base 1 and an upper mold base 2, the upper end of the lower mold base 1 is equipped with a lower template 11, and the upper end of the lower template 11 is provided with a punching avoidance hole 111 , the lower end of the upper die base 2 is equipped with a binder plate 21, and the upper end of the binder plate 21 is equipped with a vertically arranged punch 22, and the lower end of the punch 22 is provided with an inclined knife edge 221, the punch 22 It is fixedly installed on the upper end of the upper splint 23 , and the upper splint 23 is arranged on the upper end of the pressing plate 21 .

Further, the upper end of the lower die base 1 is provided with a discharge hole 12 corresponding to the punching avoidance hole 111 to facilitate the discharge of punching waste.

Further, the inclination angle a of the knife edge 221 is 1°-3°, preferably in this embodiment, the inclination angle a of the knife edge 221 is 2°.

Further, an upper backing plate 24 is installed between the upper splint 23 and the upper mold base 2 .

Further explanation is required. The utility model is provided with an inclined knife edge 221 at the lower end of the punch 22, so that the left and right ends of the knife edge 221 are not synchronized when punching the material, thereby reducing the punch 2 during punching. The punching force is reduced, thereby reducing the punching noise; therefore, the utility model has the advantages of novel design, simple structure, effectively reducing the punching force and reducing the punching noise.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
