Description
Technical field
The utility model belongs to the glass tempering apparatus technology, is specifically related to evenly air cooling equipment of the full surface of the physical toughened usefulness of a kind of glass.
Background technology
Because glass is typical brittleness material, tensile strength is low, and there is defective in the surface with inside, and the glass cracking can be expanded and cause to the surface crack that is in the tension stress district under the plus load effect.Crack propagation under the stress concentration must adopt the method for physical toughened or chemical tempering that the glass that bearing requirements is arranged is carried out the mechanics intensive treatment, forms compressive pre-stress at glass surface, guarantees that glass has higher bearing resistance, satisfies application demand.
Toughened glass as bearing structure spare not only needs to have higher bearing resistance, also needs to guarantee good face type quality simultaneously, with the seal request that guarantees to connect with other bearing structure spares.
Simultaneously,, and consider that stress relaxation may take place the glass of chemical tempering under the condition of high temperature under the higher temperatures condition, have potential risk owing to some pressure-bearing glass is required to work.Therefore, generally adopting physical toughened technology to carry out mechanics to this heatproof, pressure-bearing glass strengthens.
The physical toughened stove of plate glass mainly adopts cooling air quenching treatment process (air-cooled tempering) at present, no matter be horizontal tempering technology or vertical steel metallization processes, used air cooling equipment is normally installed the bull nozzle on the inner side plane of two air grid bodies, be connected on separately the nozzle by many air supply lines, come the flow of controlled chilling wind by the valve switch of adjusting every air supply line.Such adjustment red-tape operati complexity is difficult to be implemented in glass surface and forms the uniform cooling air of flow, causes the speed of cooling difference of the temperature on plate glass surface, causes the glass internal stress inhomogeneous, makes glass produce distortion even broken.General qualification rate can only maintain about 85%.China utility model patent specification sheets CN 201158611Y discloses a kind of flat air grid pendulous device, this device can be used for the air-cooled tempering of horizontal tempering device to glass, since the last flat air grid of this device and time flat air grid can about relative swing, so can be used to improve the glass tempering effect.
Yet, horizontal tempering technology commonly used adopts the roller bed type transporting mechanism usually, ceramic roller is parallel to the ground or angled, glass lies on the ceramic roller, all this horizontal roller formula glass tempering furnaces, when making toughened glass, glass has at least a face to contact with roller-way, glass in burner hearth, heat take place softening after, remollescent glass directly is pressed on the ceramic roller, left a trace on the toughened glass surface by the meeting that influences of gravity, form so-called roller-way seal and ripple, this seriously influences the quality of glass tempering.Therefore, general horizontal tempering technology can't realize physical toughened to the high slab glass of tempering homogeneity and face type specification of quality.
China utility model patent specification sheets CN2239966Y discloses a kind of air grid that is applicable to the air-cooled processing sheet glass tempering of glass vertical steel metallization processes, form by two identical air grid bodies, on the plane of air grid body inboard, be evenly distributed with spacing joint identical and nozzle with line-spacing, ejection and act on the surface of glass both sides with pressure and the uniform flow rate that equates from nozzle has realized the identical purpose of glass temperature rate of cooling.Yet, adopt the toughened glass of nozzle chilling moulding stress distortion defective formation stress speckle and rainbow line often to occur, influence the tempering quality of glass.
China utility model patent specification sheets CN2608497Y discloses a kind of clearance type air grid designs of nozzles principle, described air grid nozzle is improved to the slit strip, interleaved is arranged, the nozzle of this novelty has been avoided the blast uneven phenomenon, cooperate the glass mode of motion to become reciprocally swinging, glass strain is distributed more evenly rationally by one-way movement.Yet owing to need carry out the mechanical movement of reciprocally swinging, and this mechanical movement is not a uniform motion to glass, therefore still can form the inhomogeneous of glass tempering in the process of air-cooled tempering.
To sum up, this area is badly in need of a kind of air cooling equipment at present and is used to produce the equally distributed tabular toughened glass product of stress, and this air cooling equipment yet there are no report.
