Abstract
The invention discloses a kind of intensive ranking punch machining process of earpiece screen pore, step includes：Step 1, using upper and lower mould pore punching press, form the intensive ranking of aperture of certain size；Step 2, pass through trimming, material is moulding, post-tensioning shaping, one row punching masterplate of formation；Step 3, amendment side shape, product cut-out.The beneficial effects of the invention are as follows：Small hole machined and product drawing and forming synchronously completes, and improving production efficiency reduces labor intensity, and product quality is effectively ensured, and while reaching time shortening, lifts productivity.
Description
Technical field
The present invention relates to part manufacture field, particularly a kind of intensive ranking punch machining process of earpiece screen pore.
Background technology
Receiver pore processing technology typically uses etching, chemical processing technology on the market at present.Because of chemical products usability
It is limited, and chemical products easily causes environmental pollution, repeatedly, effect property length, efficiency and productivity ratio are low, and resource consumption is high for technological process.
Technique is as follows：Shear, cleaning, baking, coating, baking, exposure, development, cleaning, baking, etching, clean, move back photosensitive oil, be clear
Wash, toast, punching press, surface treatment, inspection, packaging.It is generally necessary to 18 are prepared into finished product to process, wherein there is multiple tracks chemical process
Technique, the requirement of environmental protection is not met, causes environmental pollution.
The content of the invention
The present invention, using physics pore pressing, one-stop processing, utilizes mould punching technique to improve raising efficiency
It is combined, good effect is played in the protection to environment to a greater extent, while reaching time shortening, enhances the essence of product
Density and lifting productivity, are achieved by the following technical solution.
A kind of intensive ranking punch machining process of earpiece screen pore, step include：
Step 1, using upper and lower mould pore punching press, form the intensive ranking of pore of certain size；
Step 2, pass through trimming, material is moulding, post-tensioning shaping, one row punching masterplate of formation；
Step 3, amendment side shape, product cut-out.
When the pore aperture is 0.20mm-0.25mm, mold is embedded in 0.23mm wolfram steel drifts；
Lower mould is 0.25mm circular holes in correspondence position processing aperture, is obtained using punch press up and down motion to carry out punch process
Obtain product circular hole；
Moved using the feed appliance between punch press and mould, hole mesh number needed for product can be obtained.
The circular hole edge of a knife of the drift of mold and lower mould is that high rigidity wolfram steel is made, up to per hour in punching production
250-300 jig frequencies.
The beneficial effects of the invention are as follows：Change the mode of raw material, physical deformation is changed to by original chemical process mode
Processing mode, and small hole machined and product drawing and forming synchronously complete, and improving production efficiency reduces labor intensity, is effectively ensured
Product quality, while reaching time shortening, enhance the precision and lifting productivity of product.
Brief description of the drawings
Fig. 1 is process flow diagram in the specific embodiment of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
It is that one kind is used for electronic equipment such as hand as shown in figure 1, being a kind of intensive ranking punch machining process of earpiece screen pore
Machine, flat board, the earpiece screen of notebook, in process, 10 in reference shape Fig. 1 of product, procedure of processing includes：
Step 1, using upper and lower mould pore punching press, form the intensive ranking of pore of certain size；Pass through upper/lower die
Multi-step forming, pore is by sparse to intensive, the regularly arranged some apertures of the row of formation one, as shown in figure 20.
Step 2, by machine trimming, checkrow material is cut into the material of certain length, by punch press by material it is moulding after
Drawing and forming, a row punching masterplate is formed, as shown in figure 20；
Step 3, amendment side shape, product cut-out, as shown in figure 30.
In above-mentioned steps, with reference to 30 in figure 1,40, Multi-step forming makes the pore aperture be 0.20mm-0.25mm
When, mold is embedded in 0.23mm wolfram steel drifts；
Lower mould wolfram steel drift correspondence position set aperture be the 0.25mm circular hole edges of a knife, using punch press move up and down into
Row punching press repeatedly, makes wolfram steel drift and the circular hole edge of a knife coordinate to obtain some circular holes；
Moved using the feed appliance between punch press and mould, coordinate wolfram steel drift and the circular hole edge of a knife, product can be obtained
Required hole mesh number.
The circular hole edge of a knife of the drift of mold and lower mould is that high rigidity wolfram steel is made, up to per hour in punching production
250-300 jig frequencies, make high in machining efficiency.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
