Embodiment
Adjustable glass hot bending die described in the utility model is further explained below with reference to specific embodiment
State, to make more complete and clear explanation to the technical solution of the utility model.
As shown in figure 1, adjustable glass hot bending die of the present utility model, including rectangular mould base and flexible metal
Plate.Rectangular mould base is assembled by C-type steel.Multiple screw columns, the flexible gold are provided with four frames of base
Belong to and multiple holes are provided with the surrounding of plate, the position in the hole and the position of the screw column correspond；The flexible gold
Category plate is assemblied on the screw column by the hole, and two mothers Luo, described two nuts are provided with the screw column
A lower section for being arranged on flexible metallic plate, another is arranged on the top of flexible metallic plate, passes through adjusting nut
Position and the curved face of the fixedly adjustable section flexible metallic plate.
In the utility model, the flexible metallic plate is made of D type Graphite Iron Casts, and so-called D types graphite refers to
There is well resistance in the point-like or strip graphite of No yield point distribution, i.e. dendrite graphite, D type Graphite Iron Casts between austenite dendrites
Hot, machinability and dimensional stability.D types graphite already functions as glass mold material at present, but anti-oxidant in order to improve its
Property and thermal fatigue resistance, it usually needs the addition precious metal such as Mo, Ni or rare earth, cause cost higher, and in prior art
In, for the silicone content in D type Graphite Iron Casts generally between 1.5~3.5, utility model people of the present utility model has found adding for silicon
Although thermal oxidation can be improved in D type Graphite Iron Casts Surface Creation silicon dioxide protective film layer by adding, higher Si content meetings
Cause thermal fatigue resistance to reduce, the Si contents control of the D type Graphite Iron Casts used for this utility model 0.60~
1.0wt%.Specifically, the chemical composition for the D type Graphite Iron Casts that the utility model uses is as follows：3.0~3.2wt% C,
0.60~1.0wt% Si, 0.9~1.2wt% Mn, 1.5~2.0wt% Cu, 0.05~0.25wt% Ti,
Below 0.20wt% Cr, below 0.18wt% Al, below 0.05wt% P, 0.03wt% S, surplus is Fe and not
Evitable impurity.Carbon and silicon are the graphite elements for promoting C in cast iron.The increase of carbon in cast iron content can reduce its antioxygen
The property changed, the content of carbon is controlled in 3.0~3.2wt% generally for good mechanical strength is obtained.
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, controls Mn content in more than 0.9wt% in the utility model, by the solid solution of copper, can obtain simultaneously
Refined crystalline strengthening or the effect of solution strengthening, and significantly improve mechanical strength.But if when the content of manganese is more than 1.2wt%, then
Growing up for carbon in cast iron compound is may result in, so as to cause cast iron to become fragile, deteriorates machining property, and when the content of manganese
During more than 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 is formed and crystal grain thinning, improves wearability, and increases creep resistance, but addition chromium can suppress the analysis of graphite in cast iron
Go out, so as to can seriously reduce the heat conductivilitys of D type Graphite Iron Casts, therefore the addition for the reduction chromium that should try one's best in the utility model
Amount, utility model people of the present utility model have been found that the level that Cr content is reached to more than 0.20wt%, then it is to cast iron
The negative effect of thermal conductivity will significantly improve, for this in the utility model, the Cr contents control in the D type Graphite Iron Casts
In below 0.20wt%.D type Graphite Iron Casts of the present utility model using conventional dispensing, melting, breed, pour into a mould and annealing process
It is prepared.Melting can generally be carried out in electric induction furnace, and the temperature of molten iron is needed to control at 1500~1550 DEG C, and inovulant is adopted
With Si-Fe inovulants, for molten steel pouring temperature at 1300~1350 DEG C, annealing temperature is 800~850 DEG C, and soaking time is
2.0~10.0 hours.The tensile strength of D type Graphite Iron Casts described in the utility model is 360~450MPa.
