Description
Technical field
The present invention relates to the glass heat forming furnace of glass processing device, especially a kind of cool-down method of the mobile phone 3D bend glass cover plate thermoforming stove section of cooling.
Background technology
At present, mobile phone has become one of people's interchange, life, work, amusement, study etc. than indispensable instrument, far beyond the category of call instrument, more becomes fashion product, not only will be suitable for, more want fashion; As the glass of handset viewing window also from planar development to curved surface, Samsung mobile phone realizes; But because the difficulty of processing of bend glass is large, complex process, also only has Samsung mobile phone to employ bend glass at present, home-made cellphone still can not make curve screens because of the processing problems of glass.The release of curve screens Samsung mobile phone, is also proposed the heavy demand of the flat screen protecting film of curved surface mobile phone glass; Under such prerequisite, my company has developed curved surface mobile phone glass thermoforming stove just; In view of the foregoing, domesticly the problem of processing and fabricating curved surface mobile phone glass screen can not to need to improve, now invent a kind of cool-down method of the mobile phone 3D bend glass cover plate thermoforming stove section of cooling.
Summary of the invention
The object of the invention is in order to overcome domestic existing can not processing and fabricating curved surface mobile phone glass screen, by rational design, a kind of cool-down method of the mobile phone 3D bend glass cover plate thermoforming stove section of cooling is provided, hot-forming stove comprises several stations, can continuous seepage, the efficiency of producing is high, handled easily, save energy.The glass processed can meet using of mobile phone glass and requirement.
The present invention to achieve these goals, adopt following technical scheme: a kind of cool-down method of the mobile phone 3D bend glass cover plate thermoforming stove section of cooling, a kind of mobile phone 3D bend glass cover plate thermoforming stove section of cooling, be by: N-type burner hearth temperature descending section, thermal insulation layer, rotary-tray, former, natural convection heat sink, air register, cooling convection tubes are formed; The ring-like body of heater of curved surface mobile phone glass thermoforming stove arranges N-type burner hearth temperature descending section, arranges thermal insulation layer in the interlayer of N-type burner hearth temperature descending section, and below N-type burner hearth temperature descending section, oral area arranges rotary-tray; Above rotary-tray, former is set; The top pre-opened hole of N-type burner hearth temperature descending section, in hole, natural convection heat sink is set respectively, arrange air register in natural convection heat sink, arrange cooling convection tubes below natural convection heat sink, cooling convection tubes reserves the ventilation opening of the corresponding natural convection heat sink of ventilation opening;
The mobile phone 3D bend glass cover plate of 635 DEG C-655 DEG C, by the drive of rotary-tray, enters N-type burner hearth temperature descending section, by the air-flow in the cooling convection tubes in N-type burner hearth temperature descending section by the air duct blow of ventilation opening to natural convection heat sink.While natural wind air-flow enters N-type burner hearth, also accelerate hot gas flow to send outside N-type burner hearth, form hot gas flow and the mutual fast exchange of natural wind air-flow, the high temperature in N-type burner hearth temperature descending section is reduced rapidly, 400 DEG C-500 DEG C sizings are down to curved surface mobile phone glass temperature.
Beneficial effect: hot-forming stove comprises several stations, can continuous seepage, and the efficiency of production is high, handled easily, save energy.The glass processed can meet using of mobile phone glass and requirement.
The present invention is in order to produce curved surface mobile phone glass, and it comprises heating zone, hot-forming section, the rotating disk of the section of cooling, up and down fragment and rotary motion; Rotating disk it also comprise the multiple mould of loading of rotary motion.Curved surface mobile phone glass thermoforming stove is circular, and upper of furnace body is " N " type burner hearth, and bottom is the rotating disk that can move, and both constitute a belt cavity.Annulus is divided into successively: fluctuating plate station, several heating stations, shaping station and the station that cools.Arrival cools station, this station does not have heating unit, and upper furnace has several convection holes, and aperture can regulate, be used for lowering the temperature, and latter two station cooled, in stove, forced cooling convection tubes is installed in both sides, pipe has diameter 2--5mm, the lower opening of interval 20-30mm, use blower fan to dry in pipe, accelerate cooling, guarantee temperature requirement during glass arrival fluctuating plate position.
The present invention has two kinds of cooling measures, first natural convection cooling, and the aperture by convection holes regulates, and two is in stove, be blown into wind cooling by convection flow fan and convection tubes.
Cooling process of the present invention adopts two kinds of cooling measures, and first natural convection cooling, regulates by thermal convection hole above station; Two is in stove, be blown into wind cooling by convection flow fan and convection tubes.Guarantee that the temperature of glass during glass arrival bottom sheet position is at 400-500 DEG C.
The present invention is delivered to by continuous print the section of cooling to the glass after pressing and forming together with former, has natural thermal convection hole, can regulate aperture above this station; Again through convective cooling district, use convection current air cooling, guarantee that the temperature of glass during glass arrival bottom sheet position is at 400-500 DEG C.At this moment glass is shaped.After glass arrives fluctuating plate position, take out the cooling fan be placed on outside body of heater, upper and lower surface is evenly dried; Be placed on inspection mould after the complete cool to room temperature of glass, the laminating degree of inspection glass and mould.
Hot-forming stove of the present invention comprises several stations, can continuous seepage, and the efficiency of production is high, handled easily, save energy.The glass processed can meet using of mobile phone glass and requirement.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
