A kind of single-sided overflow former for the production of ultra-thin flat glass, comprise pedestal, pedestal one end is provided with the first baffle plate, the other end is provided with second baffle, second baffle is provided with glass metal inlet, it is characterized in that being provided with overflow boss and shelves stream boss at pedestal top, overflow boss and shelves stream boss are arranged along pedestal axis direction, the overflow groove of opening upwards is provided with between overflow boss and shelves stream boss, overflow groove is arranged along pedestal axis direction, and be interconnected with glass metal inlet, same cross section perform stream boss height higher than overflow boss, described pedestal, overflow boss and shelves stream boss are integral type structure, and be made up of heating resisting metal material.After glass metal fills overflow groove, stop owing to receiving shelves stream boss, the glass metal in overflow groove can only overflow from overflow boss side.
Described pedestal, overflow boss and shelves stream boss are the integral structure that high temperature steel is made, and the overflow boss contacted with glass metal and guide face are done to the process of surfaceness, its surface roughness value is made to be less than the surface roughness value of fire proof material brick, and overflow boss and guide face frictional force respectively and between glass metal can be ensured, thus improve the working accuracy of whole pedestal, meet the requirement of formed from plate glass, further increase the planeness of the shaping sheet glass of overflow.
On the basis of technique scheme, following further technical scheme can also be had.
Described pedestal side is guide face, and guide face is arranged along pedestal axis direction, and adjacent with the overflow boss at pedestal top, bottom guide face with pedestal bottom arcs intersect form the shaping rib of arc.
The cross section of described guide face is inside arc, accelerates the flow velocity of the glass metal flowing through guide face with this.
Further technical scheme, is provided with cavity in described pedestal, is provided with the cooling fluid circulated in cavity, to reduce the surface temperature of whole pedestal, makes whole pedestal can bear the high temperature of glass metal.
Described second baffle is also provided with the cooling fluid inlet with cavity connects, first baffle plate is provided with the cooling fluid outlet with cavity connects, pedestal outside is provided with cooling back installation, cooling back installation one end and cooling fluid inlet are interconnected, and its other end and cooling fluid outlet are interconnected.
Described cooling back installation comprises drive unit, and drive unit one end and cooling fluid inlet are connected with water cooler by pipeline communication, the other end, and water cooler one end and drive unit pass through pipeline communication by pipeline communication, the other end and cooling fluid outlet.
Described cooling fluid is tin liquor.
Described drive unit is the commercially available linear electric motors in market.
Beneficial effect of the present invention is that structure is simple, reliable and stable, while the working accuracy that improve overflow former and efficiency, also reduces the thickness of the sheet glass plate of the shaping generation of overflow.
Below just accompanying drawings and embodiment the invention will be further described.
Accompanying drawing explanation
