Cost increases, and causes product competitiveness in the market not enough.
The content of the invention
The purpose of the present invention be exactly in order to solve the above-mentioned problems in the prior art, propose a kind of low cost, can be big
Amplitude improves a kind of magnet coil for acoustic pronunciation device of product yield.
The purpose of the present invention is achieved through the following technical solutions：A kind of magnet coil for acoustic pronunciation device, its
It is characterised by：It is superimposed including at least three workpiece to be added, between each described workpiece to be added and is set and coaxial, each is described to be added
By being welded to connect, the workpiece to be added is the cyclic structure of insertion in the middle of all round closure at the edge of workpiece.
Preferably, the material of the workpiece to be added is dilval.
Preferably, before the non-punching press of workpiece to be added with punching press or difference be +/- 0.010mm.
Preferably, width of the length of the workpiece to be added more than the workpiece to be added.
Preferably, the thickness of the workpiece to be added is 0.2mm.
The advantage of technical solution of the present invention is mainly reflected in：The structure can increase substantially product yield, significantly save
Material and production cost, improve the market competitiveness, make the size and performance of workpiece to be added more reliable and more stable.
Brief description of the drawings
Fig. 1 is the structural representation of workpiece to be added of the invention；
Fig. 2 is the structural representation of plunger mechanism of the present invention；
Fig. 3 is the structural representation after workpiece superposition to be added of the invention.
Specific embodiment
The purpose of the present invention, advantage and feature, by by the non-limitative illustration of preferred embodiment below carry out diagram and
Explain.These embodiments are only the prominent examples using technical solution of the present invention, it is all take equivalent or equivalent transformation and
The technical scheme of formation, all falls within the scope of protection of present invention.
As shown in figure 1, a kind of magnet coil for acoustic pronunciation device, including at least three workpiece to be added 1, each institute
Superposition is set and coaxial between stating workpiece to be added, and the edge of each workpiece to be added is by being welded to connect.It is described to be processed
Part is the cyclic structure of insertion in the middle of all round closure, and the material of the workpiece to be added is the dilvals of High Perm 49, described
Before the non-punching press of workpiece to be added with punching press or difference be +/- 0.010mm.
More than the width of the workpiece to be added 1, the length of the workpiece to be added 1 is 2.650 to the length of the workpiece to be added 1
+/- 0.02mm, in the present embodiment, the length of the workpiece to be added 1 is preferably 2.650mm；The width of the workpiece to be added 1 is
1.730+/- 0.02mm, in the present embodiment, the width of the workpiece to be added 1 is preferably 1.730mm.The workpiece to be added 1
Thickness is 0.2mm.
The workpiece to be added carries out punching press by a punching mechanism 2 to it in use, as shown in Fig. 2 the punching press
Mechanism 2 includes the cooperate upper die plate that moves up and down together and lower template 20, the upper die plate include a fixed mechanism 21 and
The punching pin 22 for being moved up and down is driven by drift, mould is provided with the lower template 20 and is entered block 23, the fixed mechanism
21 include pressing plate 211 and plate screw 212, and the fixed mechanism 21 is used for fixing the punching pin 22, specifically, the punching pin 22
It is fixed on the upper die plate by the pressing plate 211 and the plate screw 212, prevents the punching pin from occurring in use
Swing and offset.
The workpiece to be added 1 is placed between the upper die plate and the lower template, when the workpiece to be added 1 is placed in position
Afterwards, the upper die plate and mould is descending during the lower template mold closing, drift drives the punching pin 22, is pressed downward by the punching pin 22
The workpiece to be added 1 makes its thinning thickness for being needed, i.e. the workpiece to be added 1 of the punching pin 22 pairs carries out punching press makes it
Raw material are thinned to 0.2+/- 0.001mm by 0.20+0.01/-0.0mm.Only to a piece of described during 22 each punching press of punching pin
Workpiece to be added carries out punching press, and next step processing is carried out to the workpiece superposition placement to be added after the workpiece punching press to be added is good,
Being preferably after pressing 8 workpiece to be added that liquidate in the present embodiment carries out next step processing.When 8 workpiece to be added punching presses successively
After good, welded with laser machine after 8 workpiece to be added are sequentially overlapped, as shown in figure 3, being tied after being superimposed for 8 workpiece to be added 1
Structure schematic diagram.8 workpiece to be added are welded as a whole after the completion of the laser machine is radium-shine, and the size of workpiece to be added is after welding
1.6+/- 0.02mm., in the technical program, from laser machine carry out radium-shine effect be it is radium-shine it is complete after workpiece described to be added
The overall size requirement +/- 0.015mm of tolerance after superposition, tolerance is very small, improves the precision of the workpiece to be added.But work as and use radium
Penetrate the side out-of-flatness of the radium-shine rear workpiece product to be added of machine, it is radium-shine it is complete after workpiece to be added be placed on the upper die plate and
Two times punch is carried out between the lower template again, after the completion of the workpiece two times punch to be added, the side of the workpiece to be added
What is become is smooth.
The invention provides it is a kind of eliminate single product superposition after produce cumulative errors, using with microelectronics acoustics
A kind of electromagnetic sound generator in field.On the thickness that this new structure comes after the superposition of management and control product for existing dependence material tolerances
Precision has and increases substantially, and within +/- 0.015mm, monolithic product thickness allowance control exists tolerance after the superposition of 8 flake products
+/- 0.0018mm, has been really achieved yield high-accuracy, high, high stability, and comprehensive yield can reach 99.5%.The structure can be big
Amplitude improves product yield, and material and production cost is greatly saved, and improves the market competitiveness, makes the size of workpiece to be added
It is more reliable and more stable with performance.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit and essential characteristics of the invention, the present invention can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires to be limited rather than described above, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention, and any reference in claim should not be considered as the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
May be appreciated other embodiment.
