Abstract
The invention discloses a method for manufacturing blind hole curved glass, which comprises the following steps: preparing a mold having a convex portion according to a curved surface shape and a blind hole of the blind hole curved glass, wherein the convex portion is matched with the blind hole in position and shape; and placing flat glass into a mold, and carrying out hot press molding (i.e. the convex portion presses a blind hole in the glass surface) to obtain the blind hole curved glass. The method disclosed by the invention obtains the blind hole curved glass by one-time hot bending molding (i.e. the hot press molding of the blind hole is realized at the same time of the hot bending molding of the curved glass), thereby reducing the subsequent CNC blind hole carving procedure, reducing the production cost and greatly improving the working efficiency.
Description
Technical field
The present invention relates to the processing technique field of bend glass, particularly relate to the manufacturer of a kind of blind hole bend glass
Method.
Background technology
Mainly processed by CNC or etching mode is carried out it is known that do blind hole on 2D flat glass, and be also mesh
The technique of front comparative maturity.But it is relatively difficult to do blind hole on 3D bend glass, only a kind of at present mode：It is exactly bent at 3D
Carry out CNC engraving blind hole on surface glass again, waste time and energy, considerably increase cost.
Content of the invention
In order to solve above-mentioned the deficiencies in the prior art, the invention provides the manufacture method of a kind of blind hole bend glass, its
Hot bending obtains blind hole bend glass, i.e. bend glass realizes being hot pressed into of blind hole during hot bending simultaneously
Type；Not only reduce the operation of follow-up CNC engraving blind hole, also reduce production cost, substantially increase operating efficiency.
The technical problem to be solved is achieved by the following technical programs：
The manufacture method of a kind of blind hole bend glass, it comprises the following steps：Curve form according to blind hole bend glass and blind
Hole makes the mould with lug boss accordingly, this lug boss and blind hole position mating shapes；It is placed in flat glass in mould
Carrying out hot-forming, i.e. described lug boss suppresses blind hole at glass surface, it is thus achieved that blind hole bend glass.
In the present invention, described flat glass having blind hole, during hot-forming, to withstand this blind for described lug boss
Hole.The blind hole being preferably located at described flat glass is prepared by etching or CNC processing technology.
In the present invention, described mould is graphite jig.Wherein, hot-forming temperature controls at 600 ~ 800 DEG C, described heat
Molded carrying out under protective atmosphere, described protective gas is nitrogen or argon gas.
The present invention has the advantages that：This method first making one and blind hole position shape phase on graphite jig
The lug boss of coupling, when glass transition temperature, suppresses blind hole by hot-forming at glass surface, i.e. obtains blind hole after cooling
Bend glass, compared to existing technology, not only reduces the operation of follow-up CNC engraving blind hole, also reduces production cost, significantly carry
High operating efficiency, has preferable economic benefit.
On flat glass, blind hole is made in etching or CNC processing in advance, and the lug boss mating with blind hole is hot-forming
During withstand blind hole, when glass transition temperature, by the hot-forming blind hole bend glass that obtains, simultaneously ensure hot bending
Rear blind hole will not deform because expanding with heat and contract with cold, and the flatness of blind hole is very good.
Brief description
Fig. 1 is the schematic flow sheet of the manufacture method of blind hole bend glass of the present invention；
Fig. 2 is the structural representation of inventive die；
Fig. 3 is the schematic flow sheet of another manufacture method of blind hole bend glass of the present invention.
Detailed description of the invention
The present invention will be described in detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, which show the manufacturing process schematic diagram of a kind of blind hole bend glass that the present invention provides.A kind of blind
The manufacture method of hole bend glass, it comprises the following steps：
（1）The curve form to be obtained according to blind hole bend glass 4 and blind hole 5 produce the mould 1 with lug boss 2 accordingly,
As in figure 2 it is shown, this lug boss 2 and blind hole 5 position mating shapes；This mould 1 is graphite jig 1.
（2）Flat glass 3 is placed in mould 1 is carried out hot-forming, i.e. while hot pressing goes out bend glass 4, described
Lug boss 2 suppresses blind hole 5 at glass surface, and one time hot bending obtains blind hole bend glass 4.Wherein, flat glass 3 is permissible
It is 2D or 2.5D flat glass 3, but be not limited to this.
In the present invention, the temperature of hot bending controls between 600 DEG C-800 DEG C, and concrete temperature has with the material of glass
Close.Preferably, hot bending in the protective atmosphere such as nitrogen or argon gas.
It should be noted that the quantity of the quantity of lug boss, position and structure and required blind hole, position and structure
Consistent.
First this method makes the lug boss of and blind hole position mating shapes on graphite jig, at Glass Transition
During temperature, suppress blind hole by hot-forming at glass surface, after cooling, i.e. obtain blind hole bend glass, compared to existing technology,
Hot bending obtains blind hole bend glass, i.e. bend glass realizes being hot pressed into of blind hole during hot bending simultaneously
Type；Not only reduce the operation of follow-up CNC engraving blind hole, also reduce production cost, substantially increase operating efficiency, have relatively
Good economic benefit.
Make further improvements ground, as it is shown on figure 3, can be prepared by etching or CNC processing technology on flat glass in advance
Blind hole, it is thus achieved that there is the flat glass of blind hole, this blind hole and the blind hole shape and structure one on the blind hole bend glass of final finished
Cause；Then it is placed in flat glass in mould, and the blind hole on flat glass is just withstood by the lug boss of described mould, then
Carry out hot-forming, obtain blind hole bend glass.After ensureing hot bending, blind hole will not deform because expanding with heat and contract with cold, blind hole
Flatness very good.
Embodiment described above only have expressed embodiments of the present invention, and it describes more concrete and detailed, but can not
Therefore it is interpreted as the restriction to the scope of the claims of the present invention, as long as the skill that the form of employing equivalent or equivalent transformation is obtained
Art scheme, all should fall within the scope and spirit of the invention.
