Embodiment Construction

[0015] Such as image 3 and Figure 4 As shown, the straight-fall sound film punching die of the present invention includes a corresponding upper knife edge 1 and a lower knife edge 3, and the lower knife edge 3 is an annular cylinder with a hollow interior. The upper end of the lower knife edge 3 is provided with a sound film 2 to be punched, and the edge of the sound film 2 to be punched is folded inward along the vertical direction to form a positioning ring 6 that fits the outer contour of the lower knife edge. The working principle of the present invention is as follows: because the positioning ring 6 in the vertical direction of the sound film 2 to be punched fits the outer contour of the lower knife edge 3, the sound film 2 to be punched can be directly placed on the lower knife edge of the annular cylinder The upper end of 3 is fixed; start the upper knife edge 1 to punch downward, and the punched sound film can drop directly from the hollow part of the lower knife ed...

Abstract

The invention relates to punching dies, in particular to a straight down type voice diaphragm punching die used for punching voice diaphragms. The straight down type voice diaphragm punching die comprises an upper knife edge and a lower knife edge corresponding to the upper knife edge, the lower knife edge is an annular column and is hollow, a voice diaphragm to be punched is arranged at the upper end of the lower knife edge, and the edge of the voice diaphragm to be punched is folded inwards and perpendicularly to form a locating ring attached to the exterior outline of the lower knife edge. By the adoption of the structure, the voice diaphragm directly falls off from the hollow portion of the lower knife edge after being punched by the straight down type voice diaphragm punching die, so that it is avoided that the voice diaphragm is fetched after an ejection spring ejects a locating die core. The voice diaphragm directly falls off after being punched, and then the next voice diaphragm to be punched can be placed to be punched continuously, so that the punching processes are reduced, punching time is shortened, and punching efficiency is improved.

Description

technical field [0001] The invention relates to a punching die, in particular to a straight-fall sound film punching die used for punching a sound film. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. Among them, the paper cone or diaphragm is also the sound film, and the quality of the sound film is directly related to the effect of the speaker. [0003] Such as figure 1 and figure 2 As shown, the sound membranes in the prior art are all made ...
