Specific embodiment
Adjustable glass hot bending die of the present invention is further elaborated below with reference to specific embodiment, with
Phase is made more complete to technical scheme and clearly illustrates.
As shown in figure 1, adjustable glass hot bending die of the invention, including rectangular mould base and flexible metallic plate.
Rectangular mould base is assembled by C-type steel.Multiple screw posts, the flexible metallic plate are provided with four frames of base
Surrounding on be provided with multiple holes, the position in the hole corresponds with the position of the screw post；The flexible metallic plate
It is assemblied on the screw post by the hole, and two mothers Luo, the one of described two nuts is provided with the screw column
The individual lower section for being arranged on flexible metallic plate, another is arranged on the top of flexible metallic plate, by the position of adjusting nut
And the curved face of the fixedly adjustable section flexible metallic plate.
In the present invention, the flexible metallic plate is made of D type Graphite Iron Casts, and so-called D types graphite refers in Ovshinsky
Body interdendritic in No yield point distribution point-like or strip graphite, i.e. dendrite graphite, D type Graphite Iron Casts have good heat-resisting
Property, machinability and dimensional stability.Current D type graphite already functions as glass mold material, but in order to improve its inoxidizability
And thermal fatigue resistance, it usually needs the addition precious metal such as Mo, Ni or rare earth, cause it is relatively costly, and in the prior art,
Silicone content in D type Graphite Iron Casts is usual between 1.5~3.5, although the inventors found that the addition of silicon can be in D types
Graphite cast iron Surface Creation silicon dioxide protective film layer and improve thermal oxidation, but Si contents higher can cause thermal fatigue resistance
Reduce, be that the Si contents of the D type Graphite Iron Casts that this present invention is used are controlled in 0.60~1.0wt%.Specifically, the present invention is adopted
The chemical composition of D type Graphite Iron Casts is as follows：The C of 3.0~3.2wt%, the Si of 0.60~1.0wt%, 0.9~1.2wt%
Mn, the Cu of 1.5~2.0wt%, the Ti of 0.05~0.25wt%, the Cr of below 0.20wt%, the Al of below 0.18wt%,
The S of P, 0.03wt% of below 0.05wt%, balance of Fe and inevitable impurity.Carbon and silicon are to promote C in cast iron
Graphite element.The increase of carbon in cast iron content can reduce its inoxidizability, generally for the good mechanical strength of acquisition
The content of carbon is controlled in 3.0~3.2wt%.
Manganese can be effectively reduced temperature of the austenite to perlitic transformation, to obtaining fine and closely woven pearl under the conditions of continuous coo1ing
Body of light is favourable, in the present invention controls in more than 0.9wt% the content of Mn, by the solid solution of copper, can simultaneously obtain fine grain
Reinforcing or the effect of solution strengthening, and significantly improve mechanical strength.But if when the content of manganese is more than 1.2wt%, then may
Growing up for carbon in cast iron compound can be caused, so as to cause cast iron to become fragile, deteriorate machining property, and when the content of manganese exceedes
During 1.2wt%, inoxidizability can be caused to reduce.Chromium is the element commonly used in cast iron, it is generally recognized that chromium can promote pearlite matrix
Being formed and crystal grain thinning, improve wearability, and increase creep resistance, but chromium is added in cast iron can suppress the precipitation of graphite, from
And the heat conductivility of D type Graphite Iron Casts can be seriously reduced, therefore should try one's best reduce the addition of chromium in the present invention, it is of the invention
Inventor has been found that the level that the content of Cr is reached more than 0.20wt%, then the negative effect of its thermal conductivity to cast iron will
Significantly improve, be this in the present invention, Cr contents in the D type Graphite Iron Casts are controlled in below 0.20wt%.D of the invention
Type Graphite Iron Cast using conventional dispensing, melting, breed, pour into a mould and annealing process is prepared.Melting generally can be in induced electricity
Carried out in stove, the temperature of molten iron needs control at 1500~1550 DEG C, and inovulant uses Si-Fe inovulants, molten iron casting
At 1300~1350 DEG C, annealing temperature is 800~850 DEG C to temperature, and soaking time is 2.0~10.0 hours.D of the present invention
