Description

A kind of loud speaker flanging and the cutting die for the production of this flanging

Technical field

The utility model relates to loud speaker field, particularly a kind of loud speaker flanging and the cutting die for the production of this flanging.

Background technology

The vibration produced by voice coil loudspeaker voice coil during loud speaker sounding drives the vibration of drum paper, and compress or loosen ambient air, sound wave imports people's ear into sounds, flanging is generally arranged on the outer peripheral edges of speaker frame, to limit the movement position of sound basin, guarantee that sound basin moves up and down better, to ensure tonequality.

Along with science and technology and economic develop rapidly, listen to music and become the common a kind of entertainment way of modern, therefore loud speaker is seen everywhere in daily life, and as automobile audio, home theater, cinema etc. all need to use loud speaker to amplify, the use amount of therefore flanging also grows with each passing day.

The flanging manufacturing process of prior art is, is first that raw material are cut into circular semi-finished product by cutting die, then waste material in the middle of circular semi-finished product and outside is removed in cutting, obtains flanging.Because cutting die is circular, the circular semi-finished product obtained need crop a bulk of circular waste material just can obtain circular flanging, and waste material, is unfavorable for cost-saving.

Utility model content

Problem to be solved in the utility model overcomes waste material when existing flanging is produced, is unfavorable for cost-saving problem, and provide a kind of and save material, be conducive to cost-saving loud speaker flanging and the cutting die for the production of this flanging.

The utility model solves the scheme that its technical problem adopts:

A kind of loud speaker flanging, described flanging is bent by a bar blocks and forms circular or integrated at least two segmentations and stretch and form circular, and the adjacent edge that bar blocks is connected to form common edge or adjacent two segmentations relative to both sides bending is connected to form common edge.

Being improved to further technique scheme, the adjacent edge handing-over of adjacent two segmentations forms at least one then point, is describedly then positioned in common edge.

Being improved to further technique scheme, described in be segmented into fan annular or bar shaped.

Being improved to further technique scheme, described flanging is stretched by two or four or six or eight or 12 segmentations and forms.

For the production of a cutting die for loud speaker flanging, described cutting die is strip or comprises at least two partings, and at least two parting specular are arranged as two rows, and often the adjacent edge handing-over of adjacent two partings forms at least one interface point.

Being improved to further technique scheme, described parting is fan annular or bar shaped.

Being improved to further technique scheme, described cutting die comprises two or four or six or eight or 12 partings

The beneficial effects of the utility model are:

Flanging of the present utility model by one bar blocks bend form circular or integrated at least two segmentations stretch form circular, during fabrication, do not need first by cutting die cut into a circular monoblock again cutting remove part waste material broad in the middle and formed circular, raw material are greatly saved, be conducive to cost-saving, for automobile audio, the whole world probably produces 3,000 ten thousand automobiles every year, 4 loudspeaker installed by every platform automobile, adopt flanging of the present utility model, relative to prior art, each flanging can save the cost of 30% ~ 80%, then automobile audio industry can save (30% ~ 80%) * 3,000 ten thousand cost of * 4, there is good economic benefit.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Specific embodiment 1:

A kind of loud speaker flanging 100, this flanging 100 adopts the foaming kind foams such as PU foam, EPDM foam, PE foam, CR foam, NBR foam, EVA foam or PVC foam, or adopts papery class raw material to make.

This flanging 100 forms circular by a bar blocks bending, and bar blocks relative both sides bending is connected to form common edge 110.

A kind of cutting die 200 for the production of loud speaker flanging 100, cutting die 200 is in strip.Raw material are placed on cutting die 200, cross cutting is strip semi-finished product, oppositely being bent on half-finished for this strip relative both sides makes it be connected to form common edge 110 again, last cutting goes waste material namely to obtain circular flanging 100, be circular semi-finished product owing to not being first cross cutting, go waste material to obtain circular flanging 100 from the cutting of circular semi-finished product central authorities again, flanging 100 waste material area of the present utility model is little, is conducive to cost-saving.

Specific embodiment 2:

This flanging 100 is stretched by integrated four segmentations 120 and forms circular, and the adjacent edge of adjacent two segmentations 120 is connected to form common edge 110, and segmentation 120 is fan annular.

The adjacent edge handing-over of adjacent two segmentations 120 forms at least one and then puts 130, and then 130 are positioned in common edge 110.

A kind of cutting die 200 for the production of loud speaker flanging 100, cutting die 200 comprises four partings 210, and parting 210 is fan annular, and four parting 210 specular are arranged as two rows, and often the adjacent edge handing-over of adjacent two partings 210 forms at least one interface point 220.

Raw material are placed on cutting die 200, cross cutting is splayed semi-finished product, cutting is gone the waste material of these splayed semi-finished product central authorities again, obtain integrated four fan annular segments 120, and the adjacent edge of adjacent two segmentations 120 joins formation, and at least one then puts 130, these integrated four fan annular segments 120 are stretched out, makes adjacent edge be connected to form common edge 110, obtain annular flanging 100.The circular waste material area of the area ratio prior art of the central waste that cutting is gone is little by about 40%, is conducive to cost-saving.

In other embodiments, flanging 100 by integrated six or eight or 12 segmentations 120 stretch form circular, accordingly, cutting die 200 comprises six or eight or 12 partings 210, segmentation 120 increasing number, waste material area reduces, and can reduce at most the waste material of 80%, be conducive to cost-saving.

The above embodiment only have expressed a kind of execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
