Abstract
The invention discloses a simple processing process for a loudspeaker basin stand. The simple processing process for the loudspeaker basin stand comprises a series of steps of rough shape cutting, falling material stretching, lug hole punching and appearance cutting. The invention aims at providing the processing process for the loudspeaker basin stand with the advantages that each blank can be precisely punched, and the punching steps are simple.
Description
Technical field
The present invention relates to a kind of processing technology of manufacture field, particularly a kind of easy speaker frame of stereo set.
Background technology
Loudspeaker is a kind of energy transducer that the signal of telecommunication is changed into acoustical signal, and the performance quality of loudspeaker is very large on the impact of tonequality.Loudspeaker is a device the weakest in stereo set, and for acoustics, it is again most important parts.Loudspeaker of a great variety, and price differs greatly.Audio frequency electric energy is by electromagnetism, and piezoelectricity or electrostatic effect, make its cone or diaphragm vibration and produce resonance (sympathetic response) with ambient air and sound.
The structure of loudspeaker generally comprises support, magnet, basin frame, determine core and prop up sheet, the compositions such as taper cone, wherein, basin frame generally adopts steel or aluminium to make, it requires as firm, do not produce the requirements such as resonance with the sound of stereo set, present stage, the processing technology of basin frame mainly adopts the mode of monolithic raw material one-shot forming punching press to obtain, it is low that this processing technology exists size Control precision, the problem that defect ware rate is high, it is large that the air-vent of traditional basin frame has hole aperture, fragile structure, in a punching press or casting, easily there is the problem of structural damage, in actual use, also easily aging or occur the problem of metal fatigue, particularly on ultra-thin spcc material when the speaker frame of punching simple structure, the size that how to design the each embryo part of the accurate punching of stamping die is problem in the urgent need to address.
Summary of the invention
The object of this invention is to provide the accurately each embryo part of punching of one, the processing technology of the easy speaker frame of punch steps.
Technical scheme provided by the invention is: a kind of processing technology of easy speaker frame, comprises the following steps:
Step 1: sawing sheet, by shearing machine at thickness be on the SPCC coiled strip of 0.5 millimeter, cut one wide be 154 millimeters, length is the coiled strip of 1630 millimeters;
Step 2: Blanking, on described coiled strip, go out the nineteen length of side by Blanking mould and be the square raw material of 154 millimeters, and described raw material is drawn into bowl-shape semi-finished product, go out a mesopore simultaneously at the center of described bowl-shape half-finished bottom surface, the diameter of described mesopore is 10.4 millimeters, described bowl-shape half-finished bottom surface diameter is 32 millimeters, and the diameter of described bowl-shape half-finished upper surface is 65 millimeters; Described bowl-shape half-finished height is 14.6 millimeters;
Step 3: rush earhole, by rushing earhole mould at described 3 square earholes of bowl-shape half-finished side punching, the length of side of described earhole is 5 millimeters, the angle between described adjacent earhole and half-finished center of described bowl dress is 45 °;
Step 4: cut profile, by cutting epimorph, the diameter of described bowl-shape half-finished upper surface is cut into 64.7 millimeters.
In the processing technology of above-mentioned easy speaker frame, described step 4 is also carried out surface treatment step after finishing, and described surface treatment step is the interior foreign-plated trivalent chromium bright blue zinc of the speaker frame that obtains after described step 4 completes.
In the processing technology of above-mentioned easy speaker frame, described Blanking mould is arranged on 25T forcing press, and the described earhole mould that rushes is arranged on 25T forcing press, and the described epimorph of cutting is arranged on 25T forcing press.
In the present invention, this programme adopts 4 one-shot steps can complete the making of basin frame, because this basin shelf structure is simple and easy, by die-cut, stretch and rush mesopore and concentrate on a Blanking mould, a punching press can complete large-area punching operation, the punching press of earhole is placed in to the later stage and carries out, the deformation rate that has reduced ultra-thin section bar, has improved punching precision.
