Description
Technical field
The invention belongs to technical field of heat exchange more particularly to a kind of glass bending molding machine ceramic heat-exchanger rig and structures
Design.
Background technique
In recent years, at hand with the fast development of consumption electronic product and 5G communication times, glass rear shell
As important appearance component, demand is increasingly strong.Since glass optical component requires very high precision and specific
Curved surface degree, therefore, glass optical component generally use glass heat bender progress glass bending and are made, the work of bend glass hot-bending machine
Skill principle is first plus post forming cools down again, finally obtains bend glass.It can be seen that heating and cooling technique step are to pass
Important, heating and cooling process influence whether that subsequent process carries out.Bend glass hot-bending machine currently on the market there is also
The problems such as heating glass is slow, heating is uneven, largely effect on the production efficiency and the quality of production of bend glass.Currently on the market
The heat exchange plate material for being mostly used in heating and cooling is metal material, but most of refractory metal material has thermal coefficient
Low, the problems such as long-term work is easily deformable, directly influence the hot bending production efficiency and the quality of production of glass.
Although patent CN206033559U discloses a kind of efficient hot-bending machine, and discloses the ceramics with double-layer structure
Heating plate, but which kind of ceramic wafer do not used clearly, and its double-layer structure is not to be conducive to that heating plate is avoided to radiate
Optimum structure；Meanwhile currently used ceramic body, when producing higher precision and more complicated heating plate, cost is very high
, therefore constrain the raising of hot-bending machine heat exchange efficiency and the reduction of production cost.
The present invention proposes a kind of glass bending molding machine ceramics heat-exchanger rig and the plate material that exchanges heat, has heat exchange effect
Rate is high, has the characteristics that homogeneous heating and fireballing, while heat exchanger plates dimensionally stable for the mold on heat exchanger plates, will not lead
Size distortion is led to the problem of in refrigeration thermal transformation, and efficiency of heating- utilization is high, under conditions of Complex Heat hardened structure
Has feature low in cost.
Summary of the invention
The technical problem to be solved by the present invention is to for the effect that exchanges heat existing for glass bending molding machine in the prior art
The technological deficiencies such as rate is low and heating is uneven, provide a kind of ceramic heat-exchanger rig of glass bending molding machine and structure designs.
The technical scheme of the invention to solve the technical problem is:
It provides a kind of glass bending molding machine ceramic heat-exchanger rig, including ceramic heat exchanger plates, is fixed on ceramic heat exchanger plates
On mold, ceramic heat exchanger plates are connected by support body supports, supporter with fixed plate, and guide post supports a whole set of heat-exchanger rig to do
Lower movement, ceramic heat exchanger plates are heated by being embedded to heater therein, wherein the connection of ceramic heat exchanger plates and supporter connects entirely to be non-
Contacting surface connection is wrapped up or is filled using heat-barrier material in the non-working surface of ceramic heat exchanger plates, and ceramic heat exchanger plates are that thermal coefficient is big
In the silicon carbide ceramics or silicon nitride ceramics of 100w/m.k.
Different from the design structure and material of existing glass bending molding machine, the ceramic heat exchanger plates used in the present invention are supported
Body primarily serves the effect of link and fixed ceramic heat exchanger plates, can use it is any can be with material resistant to high temperature, but preferably selection
With the lower ceramic material of thermal coefficient, and the connection of ceramic heat exchanger plates and supporter is the connection of non-Full connected face, i.e., excellent
It is selected under the conditions of satisfaction supports and fixes, the contact area of supporter and ceramic heat exchanger plates is reduced to the greatest extent, to avoid the mistake of heat
It scatters and disappears more.
The present invention needs to ensure the invalid heat dissipation of non-working surface simultaneously while guaranteeing high heat exchange efficiency, is to improve
The important prerequisite of the thermal efficiency and production cost, the present invention are wrapped up or are filled the non-working surface of ceramic heat exchanger plates using heat-barrier material
Scheme can effectively solve the technical problem.Non-working surface is the ceramics heat exchange plate surface of non-contact mold in the present invention.
Silicon carbide or silicon nitride ceramics are as having excellent thermal conductivity and thermal shock resistance, as of the invention preferred
Ceramic material, the present invention test discovery select thermal coefficient be greater than 100w/m.K ceramic material, it is ensured that heat exchange efficiency
It is also possible to guarantee temperature shock under the conditions of room temperature is to 600 DEG C of temperature alternatings, ceramics will not be caused to rupture and fail.
Wherein, as thyrite, siliceous silicon carbide ceramics has optimal thermal coefficient and thermal shock resistance
And elevated temperature strength, while use collosol and gel adds the technique of reaction-sintered, the ceramics for being easily obtained inexpensive complicated shape change
Thermal device.
The preferred thermal coefficient of heat-barrier material be less than 5w/m.k refractory material, refractory material be asbestos friction material, diatomite product,
One of ceramic, mineral fiber product, high temperature inorganic coating, silicate product or multiple combinations.
