Abstract
The invention discloses a kind of web plate materials to stretch the indeformable technique of mesh, belong to web plate technical field of material formation, it is far above the characteristic of web plate Porous materials intensity using whole timber intensity, it breaks the normal procedure the architectural concept of simple mesh material, the obstructed netted blind hole worn is etched on thicker whole plank；Then the material for possessing the netted blind hole of half storey, the intact plank of half storey is sent into mold and carries out drawing and forming, protect netted blind hole not to be pulled out of shape using the intact layer material of outer layer；It finally puts the semi-finished product of complete forming into etching solution again and erodes the intact material of outside half storey, to leave conceivable external form in place and product that hole is not pulled out of shape, avoid traditional web plate hole gently once draw deformation even fracture the drawbacks of.Etch process of the present invention is common, highly practical, can be solved perfectly that sound equipment, the mesh form of microphone be different, each orientation sound effect distinguishes big defect, greatly improve sound equipment, the appearance of microphone and acoustical quality aesthetic feeling.
Description
Technical field
The present invention relates to drawing and forming fields, and the indeformable technique of mesh is stretched more particularly to a kind of web plate material.
Background technology
Sound equipment and microphone are not only individual electronic product, and are also widely used for mobile phone, computer, TV, game machine
On equal electronic products.Its aesthetic appearance and acoustical quality can determine the class of a product.Our sound equipments on the market now
Or with microphone mostly simple shape or somewhat its surface mesh of curve form be exactly it is irregular, each region
Mesh form is different, and the difference of different direction acoustical quality is big in actual use.The reason of causing this phenomenon is exactly traditional web plate
The strength of materials is weak, and hole gently once drawing deformation to be even broken, can not carry out the deformation of small curvature.
Support it in stretching die using the intensity for remaining complete material it would therefore be highly desirable to provide a kind of novel manufacturing process
Hole is not pulled out of shape when molding in tool.Final etching fall to complete mission it is unnecessary continue retain some materials, obtain finally at
Product.Each region mesh of product is uniform in this way, uniform.Sound equipment, the appearance of microphone and acoustical quality can be greatly improved
Aesthetic feeling, promoted user experience.
Invention content
The invention mainly solves the technical problem of providing a kind of web plate materials to stretch the indeformable technique of mesh, can break through
The present situation that conventional mesh form beauty can not get both with product global shape beauty.Using remaining complete layer material after layers of material
Intensity, hole is not pulled out of shape when its entirety being supported to be molded in drawing die, then through corrosion obtain final finished.Overcome mesh
Gently once drawing deformation to be even broken, the problem of the forming of small curvature can not be carried out, to ensure the appearance and sound of sound equipment, microphone
The aesthetic feeling of matter effect promotes user experience.
In order to solve the above technical problems, one aspect of the present invention is：A kind of web plate material stretching nets are provided
The indeformable technique in hole includes mainly following process：
One, process one-etches netted blind hole：
S1, first selection meets the sheet stock that drawing die designs length and width dimensions, the pass of material thickness T and final products material thickness t
System is t=55%T~65%T；
S2, it this sheet stock is subjected to the blind mesh of single side again etches, the depth bounds of blind hole are 70%T~80%T, hole shape
By final products shape, the unilateral small 18%T~25%T of diameter dimension in bore dia size ratio final products hole；
S3, logical consistent with drawing die design of etching simultaneously wears type location hole on this sheet stock, with ensure to have etched
The accuracy that it is positioned when material is put into drawing die；
Two, two-drawing and forming of process：
S4, that the material etched is had to blind hole contact in facing with stretching convex die, will not etch logical that and face outwardly
It is contacted with cavity plate is stretched, puts drawing die drawing and forming into, the stretching convex die appearance and size of final molding is than final products
The interior small 18%T~25%T of shape size, shape size is bigger than the appearance and size of final products in the stretching cavity plate of final molding
18%T~25%T；
Three, process three-etches finished product：
S5, the semi-finished product of the complete forming of shape are entirely put to etching solution progress general corrosion into, according to two work of front
The parameter that sequence is preset obtains size and shape after the material of 18%T~25%T is fallen in all surface corrosions of this semi-finished product
The finished product consistent with final products.
Preferably, the location hole that the location hole come will be designed with the drawing die of two S4 of process is etched in one S3 of process
Size, position are completely the same, to ensure position is connected between two-step accuracy.
Preferably, the relationship of the material thickness T and final products material thickness t of sheet stock described in S1 is t=60%T.
Preferably, the depth bounds of blind hole described in S2 are 80%T, the diameter ruler in blind hole diameter size ratio final products hole
Very little unilateral small 20%T.
Preferably, the stretching convex die appearance and size of final molding is smaller 20%T than the interior shape size of final products in S4, most
Shape size is bigger 20%T than the appearance and size of final products in the stretching cavity plate of final shaping unit.
Preferably, the semi-finished product of the complete forming of shape are entirely put into etching solution in S5 and carries out general corrosion, according to
The parameter that front two-step is preset obtains size and shape after the material of 20%T is fallen in all surface corrosions of this semi-finished product
The finished product consistent with final products.
The beneficial effects of the invention are as follows：1, break through what conventional mesh form beauty can not get both with product global shape beauty
Present situation, using the intensity for remaining complete layer material after layers of material, hole is not drawn when its entirety being supported to be molded in drawing die
Deformation；
2, it is not specially required due to being etched twice before and after the present invention, it is raw that batch can be realized in normal etch producer
Production, does not influence efficiency and production capacity at all；
3, inventive die structure is also simple, highly practical, without because what is stretched is web plate material and does special place
Reason；
4, the present invention improves the class of its affiliated electronic product from aesthetic appearance and actual sound quality effect.
