Abstract
The invention belongs to voice diaphragm forming auxiliary equipment, and particularly relates to an automatic voice diaphragm forming voice diaphragm tensioning mechanism. The novel voice diaphragm forming tensioning mechanism comprises a base and is characterized in that a lower die is arranged in the middle of the base, drive devices are symmetrically arranged on the two sides of the lower die, the movable ends of the drive devices are connected with a diaphragm pressing plate, and a forming through hole is formed in the middle of the diaphragm pressing plate. By the adoption of the automatic voice diaphragm forming tensioning mechanism, the problem that the appearance of a voice diaphragm is poor in manual operation is solved, unit capacity is greatly improved, and labor cost is reduced.
Description
Technical field
The invention belongs to the shaping auxiliary equipment of sound film, the sound film strainer that particularly a kind of sound film of automation is shaping.
Background technology
Sound film is as the sound-generating element of loud speaker, and the performance of integrality on loud speaker of its shape has important impact.
In existing production process, tensioning tool is adopted to the tensioning of sound film of loudspeaker, need manually by lower tool fixing for sound film, then upper tool covered and be fixedly connected with by the upper and lower tool of screw, then be placed on mould carries out shaping, the manually-operated time is longer, and efficiency comparison is low, cannot meet the needs of production.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the strainer that the sound film of automation of the present invention is shaping, avoid the problem of the sound film bad order that manual work exists, meanwhile, the unit production capacity that the present invention also improves greatly, reduces cost of labor.
The present invention is achieved through the following technical solutions:
The strainer that novel sound film is shaping, it comprises base, it is characterized in that: the bilateral symmetry that the middle part of described base is provided with bed die is provided with drive unit, and the movable end of drive unit is connected with thin film platen, and the middle part of thin film platen is provided with forming through hole.
The present invention drives moving up and down of thin film platen realize the tensioning of sound film and unclamp by drive unit, achieve the automation of sound film tensioning, without the need to manually operating, improve production efficiency, overcoming bad order and the low problem of production efficiency that manual work exists.
The surrounding that the lower surface of described thin film platen is positioned at forming through hole is provided with compression rubber, the compression rubber arranged can improve the frictional force between thin film platen and sound film, thus ensure that the thrust of thin film platen to sound film, overcome the shaping inaccurate problem of sound film because tensile force deficiency causes.
The upper surface of described bed die is provided with the groove of annular, and the lower surface of thin film platen is provided with the flange with groove fit.
Further, described groove is curved.
Further, described groove semicircular in shape.
The profile design of above-mentioned groove, can increase the contact area of thin film platen and sound film, increases thin film platen to the tensile force of sound film, thus ensure that the accuracy that sound film is shaping.
In sum, the present invention has following beneficial effect:
The present invention devises the shaping strainer of a kind of sound film of automation, overcome the loaded down with trivial details of manual operation tool in prior art and location inaccurate and locate the shaping problem not in place of the inaccurate sound film brought, the present invention only needs manually to be placed on lower tool by sound film, drive unit drives thin film platen to press down and positions and tensioning sound film, ensure that the dynamics of the accuracy that sound film is located and tensioning, overcome the shaping bad problem of sound film, but also substantially increase unit production capacity, reduce cost of labor.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Execution mode one
The strainer that novel sound film is as shown in Figure 1 shaping, it comprises base 1, it is characterized in that: the bilateral symmetry that the middle part of described base 1 is provided with bed die 4 is provided with drive unit 2, described drive unit is the cylinder of oscilaltion, the movable end of drive unit 2 is connected with thin film platen 3, the middle part of thin film platen 3 is provided with forming through hole 31, and the diameter of described forming through hole 31 is slightly larger than the diameter of bed die 4 through hole;
The present invention drives moving up and down of thin film platen realize the tensioning of sound film and unclamp by drive unit, achieve the automation of sound film tensioning, without the need to manually operating, improve production efficiency, overcoming bad order and the low problem of production efficiency that manual work exists.
The surrounding that the lower surface of thin film platen 3 is positioned at forming through hole is as shown in Figure 4 provided with and compresses rubber 33, the compression rubber arranged can improve the frictional force between thin film platen and sound film, thus ensure that the thrust of thin film platen to sound film, overcome the shaping inaccurate problem of sound film because tensile force deficiency causes.
Execution mode two
The upper surface of bed die is as shown in Figure 5 and Figure 6 provided with the groove 41 of annular, and the lower surface of thin film platen 3 is provided with the flange 32 with groove fit, and described groove 41 is curved, the shape of flange and groove with the use of.
Execution mode three
As shown in figure 5 and figure 7, the upper surface of bed die is provided with the groove 41 of annular, and the lower surface of thin film platen 32 is provided with the flange with groove fit, and described groove 41 semicircular in shape, the shape of flange and the identical of groove, both with the use of.
The profile design of above-mentioned groove, can increase the contact area of thin film platen and sound film, increases thin film platen to the tensile force of sound film, thus ensure that the accuracy that sound film is shaping.
In sum, the present invention has following beneficial effect:
The present invention devises the shaping strainer of a kind of sound film of automation, overcome the loaded down with trivial details of manual operation tool in prior art and location inaccurate and locate the shaping problem not in place of the inaccurate sound film brought, the present invention only needs manually to be placed on lower tool by sound film, drive unit drives thin film platen to press down and positions and tensioning sound film, ensure that the dynamics of the accuracy that sound film is located and tensioning, overcome the shaping bad problem of sound film, but also substantially increase unit production capacity, reduce cost of labor.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
