Single-sided overflow former.
The purpose of the present invention is achieved by the following technical programs.
A kind of single-sided overflow former for being used to produce ultra-thin flat glass, including pedestal, pedestal one end is provided with first gear
Plate, the other end are provided with second baffle, and second baffle is provided with glass metal inlet, it is characterised in that overflow is provided with the top of pedestal
Boss and shelves stream boss, overflow boss and shelves stream boss are set along pedestal axis direction, between overflow boss and shelves stream boss
Overflow launder provided with opening upwards, overflow launder is set along pedestal axis direction, and is interconnected with glass metal inlet, same
The height for flowing boss is performed higher than overflow boss in cross section, and the pedestal, overflow boss and shelves stream boss are integral type structure, and
It is made up of heating resisting metal material.After glass metal fills overflow launder, stop due to receiving shelves stream boss, the glass in overflow launder
Glass liquid can only overflow from overflow boss side.
The pedestal, overflow boss and shelves stream boss are the integral structure that is made of heat resisting steel, and pair are contacted with glass metal
Overflow boss and guide face make the processing of surface roughness, its surface roughness value is less than the rough surface of fire proof material brick
Angle value, and overflow boss and the guide face frictional force between glass metal respectively are ensure that, so as to improve adding for whole pedestal
Work precision, meets the requirement of formed from plate glass, further increases the flatness of the plate glass of overflow shaping.
On the basis of above-mentioned technical proposal, there can also be technical scheme further below.
The pedestal side is guide face, and guide face is set along pedestal axis direction, and convex with overflow at the top of pedestal
Platform is adjacent, and guide face bottom is intersected with pedestal bottom circular arc and forms arc shaping rib.
The cross section of the guide face is inside arc, the flow velocity for accelerating to flow through the glass metal of guide face with this.
It is provided with further technical scheme, the pedestal in cavity, cavity provided with the coolant circulated, to reduce
The surface temperature of whole pedestal, makes whole pedestal to bear the high temperature of glass metal.
The coolant inlet connected with cavity is additionally provided with the second baffle, first baffle is provided with and connected with cavity
Coolant outlet, cooling back installation is provided with outside pedestal, cooling back installation one end is mutually interconnected with coolant inlet
Logical, its other end is interconnected with coolant outlet.
The cooling back installation includes drive device, drive device one end and coolant inlet by pipeline communication,
The other end is connected with cooler, and cooler one end passes through pipe with drive device by pipeline communication, the other end and coolant outlet
Road is connected.
The coolant is tin liquor.
The drive device is the commercially available linear electric motors in market.
The beneficial effects of the present invention are simple in construction, reliable and stable, improve the machining accuracy of overflow former and
While efficiency, the thickness for the plate glass plate that overflow shaping is produced is also reduced.
Just it is described with reference to the drawings that the invention will be further described with embodiment below.
Brief description of the drawings
Fig. 1 is main structure diagram of the present invention；
Fig. 2 is Fig. 1 A-A section mplifying structure schematic diagrams.
Embodiment
As depicted in figs. 1 and 2, a kind of single-sided overflow shaping for being used to produce ultra-thin flat glass provided for the present invention
In device, including the internal pedestal 1 for being provided with cavity 1c, cavity 1c first is provided with provided with the coolant 3 circulated, the one end of pedestal 1
Baffle plate 8, first baffle 8 is provided with the coolant outlet 8a connected with cavity 1c, and the other end of pedestal 1 is provided with second baffle 2, the
Two baffle plates are interconnected provided with coolant inlet 2b, coolant inlet 2b and cavity 1c, and the outside of pedestal 1, which is provided with, to be followed
Ring cooling device 4, following cooling back installation 4 includes drive device 5, and the one end of drive device 5 passes through pipe with coolant inlet 2b
Road 7 is connected, the other end is connected with cooler 6, and the one end of cooler 6 is connected with drive device 5 by pipeline 7, the other end and coolant
Outlet 8a is connected by pipeline 7；Described second baffle 2 is provided with glass metal inlet 2a, and the top of pedestal 1 is convex provided with overflow
Platform 1a and shelves stream boss 1f, overflow boss 1a and shelves stream boss 1f are set along the axis direction of pedestal 1, and in overflow boss 1a and
The overflow launder 1b of opening upwards is provided between shelves stream boss 1f, overflow launder 1b is set along the axis direction of pedestal 1, and is noted with glass metal
Entrance 2a is interconnected, and the height for the stream boss 1f that performed in same cross section is higher than overflow boss 1a；It is described with overflow boss 1
The adjacent side of pedestal 1 is guide face 1d, and guide face 1d is set along the axis direction of pedestal 1, and guide face 1d cross section is inside
Arc, guide face 1d bottoms intersect with the bottom circular arc of pedestal 1 and formed arc shaping rib 1e, when glass metal fills overflow launder 1b
Afterwards, stop due to receiving shelves stream boss 1f, the glass metal in overflow launder 1b overflows through overflow boss 1a to guide face 1d；Institute
The pedestal 1 and its guide face 1d stated are the integral structure that heat resisting steel is made.
Glass metal is injected into overflow launder 1b through glass metal inlet 2a, at the same time, is started drive device 5, is made cooling
Liquid 3 is circulated through pipeline 7 between cavity 1c and cooler 6, so that the temperature for the whole pedestal that heating resisting metal is made is reduced,
Because shelves stream boss 1f height is higher than overflow boss 1a, stopped that the glass metal of spilling is in the spy of itself by shelves stream boss 1f
Property effect and Action of Gravity Field under, can only overflow, be led when glass metal is flow to from overflow boss 1a sides in overflow launder 1b glass metal
During stream interface 1d, because guide face 1d cross section is inside arc, and its surface roughness value is low, is led so as to accelerate and flow through
The flow velocity of stream interface 1d glass metal, while also reducing the thickness of glass metal at this, final glass liquid is molded rib 1e shapes through arc
Into the glass plate of respective thickness.
