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
The present invention relates to a kind of die cutting die, particularly a kind of vertical sound film die cutting die being used for die-cut sound film.
Background technology
Loud speaker is a kind of energy transducer signal of telecommunication being changed into acoustical signal, and the performance of loud speaker is good and bad very large on the impact of tonequality.Loud speaker is a device the weakest in stereo set, and for acoustics, it is again most important parts.Loud speaker of a great variety, and price differs greatly.Audio-frequency electric is by electromagnetism, and piezoelectricity or electrostatic effect, make its cone or diaphragm vibration and produce with ambient air resonate (sympathetic response) and sound.Wherein cone or diaphragm i.e. sound film, the quality of sound film quality is directly connected to the effect of loud speaker.
As depicted in figs. 1 and 2, prior art middle pitch film all becomes version to make, and every edition sound film comprises several sound films, needs to be got off die-cut for each sound film by die cutting die.Be provided with location core rod 4 in the lower edge of a knife 3 of existing sound film die cutting die, below described location core rod 4, be fixed with ejector spring 5.Time die-cut, sound film 2 to be punched be placed on the core rod 4 of location fixing, then press down the edge of a knife 1 by out die-cut for sound film; Die-cut complete after the edge of a knife 1 in lifting, and by ejector spring 5, location core rod 4 to be ejected, thus the sound film that location core rod 4 upper punch cuts is taken out, then put into next sound film to be punched and carry out die-cut.This sound film die cutting die is die-cut complete after need by ejector spring, location core rod to be ejected, operating time and operation are all more, and the efficiency of the sound film of production is lower.
Summary of the invention
It is high that the technical issues that need to address of the present invention are to provide a kind of die-cut efficiency, the sound film die cutting die of simple operation.
For solving above-mentioned technical problem, vertical sound film die cutting die of the present invention comprises the corresponding upper edge of a knife and the lower edge of a knife, and the described lower edge of a knife is ring-type cylinder, inner hollow; Described lower edge of a knife upper end arranges sound film to be punched, and described sound film edge to be punched vertically infolding forms the centring ring fitted with lower edge of a knife exterior contour.
Further, described lower edge of a knife diameter is d, and sound film diameter to be punched is D, described D-0.05mm≤d≤D.
Further, material collecting box is placed with below the described lower edge of a knife.
Adopt after said structure, vertical sound film die cutting die of the present invention sound film is die-cut complete after, sound film directly from the lower edge of a knife vacancy fall, just by ejector spring, location core rod is not ejected, then sound film is taken out; Die-cut complete after sound film directly fall, just can put into next sound film to be punched and continue die-cut; Thus save die-cut operation, save the die-cut time, improve die-cut efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of prior art middle pitch film die cutting die.
Fig. 2 is the schematic cross-section of Fig. 1 of the present invention.
Fig. 3 is the structural representation of sound film die cutting die of the present invention.
Fig. 4 is the schematic cross-section of Fig. 3 of the present invention.
In figure: 1 is the upper edge of a knife, 2 is sound film to be punched, and 3 is the lower edge of a knife, and 4 is location core rod, and 5 is ejector spring, and 6 is centring ring
Embodiment
As shown in Figure 3 and Figure 4, vertical sound film die cutting die of the present invention comprises the corresponding upper edge of a knife 1 and the lower edge of a knife 3, and the described lower edge of a knife 3 is ring-type cylinder, inner hollow.The described lower edge of a knife 3 upper end arranges sound film 2 to be punched, and described sound film 2 edge to be punched vertically infolding forms the centring ring 6 fitted with lower edge of a knife exterior contour.Operation principle of the present invention is as follows: because the centring ring 6 of the vertical direction of sound film 2 to be punched fits, so the upper end of the edge of a knife 3 is fixed under sound film 2 to be punched directly can being enclosed within ring-type cylinder with the exterior contour of the lower edge of a knife 3; In startup, the edge of a knife 1 is die-cut downwards, and die-cut good sound film can directly fall from the hollow space of the lower edge of a knife 3; Then upwards lift the edge of a knife 1 and just then can put into next sound film 2 to be punched, eliminate die-cut good sound film jack-up and the operation of taking out, improve the die-cut efficiency of sound film.
Further, as depicted in figs. 1 and 2, adopt the diameter of the lower edge of a knife 3 to be larger than the diameter of sound film 2 to be punched in prior art, be generally greater than sound film diameter 5 to be punched.And the present invention adopts vertical die cutting die, as shown in Figure 3 and Figure 4, owing to not locating the support of core rod in the process that the upper edge of a knife 1 presses down, the upper edge of a knife 1 can produce a downward pressure to sound film to be punched, make sound film to be punched surface opening slightly, under designing, during the size of the edge of a knife 3, the diameter of the lower edge of a knife can be less than slightly sound film diameter to be punched like this.Described lower edge of a knife diameter is d, and sound film diameter to be punched is D, described D-0.05mm≤d≤D; In the present embodiment, lower edge of a knife diameter d=sound film diameter to be punched is D-0.05mm.
Further, conveniently collect the die-cut good sound film fallen from lower edge of a knife hollow bulb, below the described lower edge of a knife, be placed with material collecting box.
Although the foregoing describe the specific embodiment of the present invention; but those skilled in the art are to be understood that; these only illustrate; various changes or modifications can be made to present embodiment; and not deviating from principle and the essence of invention, protection scope of the present invention is only defined by the appended claims.
