Summary of the invention
It is an object of the invention to provide the manufacture method of the vibrating diaphragm of a kind of moving-iron type receiver, in order to solve
Prior art produces the problem that vibrating diaphragm efficiency is low and concordance is bad.
The first aspect of the invention is to provide the manufacture method of the vibrating diaphragm of a kind of moving-iron type receiver, including
Following steps:
Multi-disc flutter is respectively put in many die cavitys forming jig, and carries out feeding pretreatment;
Pretreated for feeding forming jig is carried out hot briquetting process;
Forming jig after processing hot briquetting carries out die sinking and carries out flutter separation.
Further, the operation carrying out feeding pretreatment specifically includes:
Peace and quiet thin film is covered on forming jig;
Material returned auxiliary frame is placed on forming jig, to push down thin film surrounding completely;
Vibrating diaphragm carriage assembly is placed on forming jig, by the hole, location of vibrating diaphragm carriage assembly both sides and
Alignment pin on forming jig positions.
Further, the operation that pretreated for feeding forming jig carries out hot briquetting process is specifically wrapped
Include: the forming jig completed by feeding is stably placed on the platform of heater, to carry out vacuum, conjunction
Mould, heating, molding, be incubated and cooling process.
Further, the forming jig after processing hot briquetting carries out die sinking and carries out the behaviour of flutter separation
Specifically include: after dropping to low temperature setting value at a temperature of when, open mould, by the vibrating diaphragm after molding and one-tenth
Type tool together takes out, and vibrating diaphragm is separated into multiple monomer.
Further, thin film uses polyurethane film.
Further, the operation of heat treated is particularly as follows: with the programming rate of 20 ± 3 degree per second by molding
Tool is heated to setting value from room temperature.
Further, the operation of isothermal holding is particularly as follows: utilize thermal inertia, after cut-out adds thermocurrent,
Temperature be maintained at setting value ± 3 DEG C in, its temperature retention time controlled at 5~8 seconds.
Further, setting value is 135 ± 5 degree.
The invention described above technical scheme is used to provide the benefit that: by using integrated many die cavitys to become
Type tool, thus realize multi-disc vibrating diaphragm one-shot forming, greatly improve the production efficiency of vibrating diaphragm, reduce
Production cost, and stability and the concordance of vibrating diaphragm be effectively ensured.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.
The invention provides the manufacture method of the vibrating diaphragm of a kind of moving-iron type receiver, as it is shown in figure 1, include
Following steps:
Step S101, is respectively put into multi-disc flutter in many die cavitys forming jig, and carries out feeding pretreatment;
In the present embodiment, the operation carrying out feeding pretreatment specifically includes: first, is divided by multi-disc flutter
Do not put in many die cavitys forming jig, in the present embodiment, at most can put into 15 flutters, every flutter
Being correspondingly placed in a die cavity of forming jig, the porose side of flutter is near the runway of forming jig, separately
Side is hinge side, the hinge moved for vibrating diaphragm, in this step, it is necessary to assure the cleaning of environment, as
There is no the foreign bodies etc. such as macroscopic fiber, dust;Then, the thin film of suitable dimension will be cut in advance
Cover on forming jig, be substantially centered, it is possible to the plane all covering forming jig is advisable, and thin film
After lay completes, it is impossible to have obvious gauffer, thin film can not adhesive tape foreign body, concrete, its thin film can be adopted
Use polyurethane film;Material returned auxiliary frame is placed on forming jig, thin film surrounding is pushed down completely, and
And vibrating diaphragm the most significantly arches upward and gauffer;Finally vibrating diaphragm carriage assembly is placed on forming jig, covers
Glue surface down, carries out correspondence by the alignment pin positioned on hole and forming jig of vibrating diaphragm carriage assembly both sides
Location, thus complete the operation of feeding pretreatment.
Step S102, carries out hot briquetting process by pretreated for feeding forming jig;
In the present embodiment, the forming jig completed by feeding is stably placed on the platform of heater,
Handling process can not have collision or significantly shake, with carry out vacuum, matched moulds, heating, molding,
Insulation and cooling process.Concrete, first start vacuum equipment, thus flutter absorption is controlled in molding
In the acupuncture point of tool, in whole forming process, vacuum power can ensure that flutter will not produce displacement;Then enter
Row matched moulds, forming jig is pressed on the platform of heater under cylinder action by upper mold, due to upper mold table
Face covers the high temperature resistant foam of one layer of 2mm, may consequently contribute to the mutually isolated of 15 caves on forming jig
With airtight, can't hear the sound of obvious gas leakage with human ear, its cylinder intake pressure is maintained at 6kg
Left and right;Then open heater to begin to warm up, and with the programming rate of 20 ± 3 degree per second by forming jig
Being heated to setting value from room temperature, concrete, its setting value is 135 ± 5 degree;Then, molding gas is opened
Pressure, and keep omnidistance pressure 5.5~5.8kg, whole during the air-tightness of system to be ensured, with people
Ear be can't hear air-flow and gushed sound;And utilize thermal inertia, after cutting off heater current, temperature keeps
Setting value ± 3 DEG C in, and its temperature retention time controls at 5~8 seconds;Finally cool down, open cold
But water solenoid valve, drops to room temperature by mold temperature, and the temperature of its cooling water controls at 8~10 DEG C, cooling
Speed is at more than 8 DEG C per second.
Step S103, the forming jig after processing hot briquetting carries out die sinking and carries out flutter separation.
In the present embodiment, when at a temperature of drop to low temperature setting value after, open mould, and simultaneously will be all
Reset, together takes out the vibrating diaphragm after molding and forming jig, and then vibrating diaphragm is separated into multiple list
Body, and be placed in pallet, thus complete the course of processing of vibrating diaphragm.
The present invention is by using integrated many die cavitys forming jig, thus realizes multi-disc vibrating diaphragm and once become
Type, greatly improves the production efficiency of vibrating diaphragm, reduces production cost, and vibrating diaphragm has been effectively ensured
Stability and concordance.
