Abstract
The utility model provides an unsmooth type of woofer china department, includes base plate (1), the center of base plate (1) be equipped with boss (2), boss (2) be equipped with central through hole (2.1), boss (2) and base plate (1) formula structure as an organic whole, this integral type structure is the forging and pressing formed part. This unsmooth type of woofer china department enables the woofer and wholly does more frivolously.
Description
Technical field
The utility model relates to woofer technical field, specifically refers to a kind of woofer concave-convex type washer.
Background technology
Comparatively common woofer washer is generally in tabular, overall axial length is not long, like this under the constant prerequisite of woofer stroke, just must increase the axial length of the miscellaneous part of woofer, namely increase the thickness of miscellaneous part to ensure the stroke of woofer.The integral thickness of whole like this woofer is then thicker, frivolous not.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of woofer concave-convex type washer that woofer entirety can be made to do more frivolous.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: comprise substrate, and the center of described substrate is provided with boss, and described boss is provided with central through hole, and described boss and substrate are integral type structure, and this integral structure is for forging into shaped piece.
Described boss is up-narrow and down-wide cone boss, and cone boss is convenient to forging forming.
The madial wall of described central through hole is upright side walls, and upright side walls is convenient to subsequent fine processing.
The position that substrate is connected with boss is provided with annular groove, and described annular groove is arranged on the upper surface of substrate, the setting of annular groove, effectively can be connected with boss the thickness at position by thinning substrate, to ensure the consistent of whole washer thickness, so that forging forming.
Woofer concave-convex type washer of the present utility model is because being provided with boss, this boss effectively can increase the axial length of whole washer, like this when woofer total kilometres are constant, the miscellaneous part of woofer just can do more frivolous, and such woofer just entirety is more frivolous.And the washer of the integral formula structure of forging forming, the density of washer material therefor can be changed when forging and pressing, effectively can increase magnetic flux.
Accompanying drawing explanation
Accompanying drawing is the sectional structure schematic diagram of the utility model woofer concave-convex type washer.
Shown in the utility model figure: 1 substrate, 2 boss, 2.1 central through holes, 3 annular grooves.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, woofer concave-convex type washer of the present utility model, comprise substrate 1, unlike the prior art, the center of described substrate 1 is provided with boss 2, described boss 2 is provided with central through hole 2.1, and described boss 2 is integral type structure with substrate 1, and this integral structure is for forging into shaped piece.
In the present embodiment, described boss 2 is up-narrow and down-wide cone boss, and cone boss is convenient to forging forming.
The madial wall of described central through hole 2.1 is upright side walls, and upright side walls can facilitate subsequent fine to process.
The position that substrate 1 is connected with boss 2 is provided with annular groove 3, and described annular groove 3 is arranged on the upper surface of substrate 1.
Woofer concave-convex type washer of the present utility model is because of the setting of boss, effectively can increase axial length, thus make the miscellaneous part of woofer do more frivolous, and woofer concave-convex type washer of the present utility model is because of overall forging forming, density of material can be changed, the thickness of thinning substrate while can ensureing magnetic flux, can make woofer concave-convex type washer of the present utility model do more more frivolous further.
Claims (4)
