The object of the invention is still can not make the deficiency of curve screens to overcome existing home-made cellphone because of the processing problems of glass, by appropriate design, provide a kind of heating process of mobile phone 3D bend glass cover plate thermoforming stove heating zone, the present invention adopts heat-resistance stainless steel to make mould, mould heat absorption is fast, produce thermal radiation to glass from bottom, be conducive to glass heats synthesis type, 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 heating process of mobile phone 3D bend glass cover plate thermoforming stove heating zone, described a kind of mobile phone 3D bend glass cover plate thermoforming stove heating zone, be by: N-type burner hearth, thermal insulation layer, top stove silk, lower radiator tube, rotary-tray, former chassis, former are formed; The heating zone of curved surface mobile phone glass thermoforming furnace body is set to N-type burner hearth, and arrange thermal insulation layer in the interlayer of N-type burner hearth body of heater, below N-type burner hearth, oral area arranges ring-like rotary-tray; Arrange thermal insulation layer above rotary-tray, arrange former chassis above thermal insulation layer, former arranges former above chassis; Arranged transversely top, N-type burner hearth middle and upper part stove silk, arranges lower radiator tube below the stove silk of top, and above former correspondence, lower radiator tube is arranged;
After the electric power starting of curved surface mobile phone glass thermoforming stove, the stove silk in N-type burner hearth and lower radiator tube release of heat simultaneously, defines the cross one another heat energy of waviness, heats in N-type burner hearth.
In N-type burner hearth, temperature rises to 700 DEG C--and when 725 DEG C, drive the curved surface cover-plate glass in former to run by rotary-tray, send in the N-type burner hearth of body of heater heating zone; Curved surface cover-plate glass, by the time period of heating zone, is subject to 700 DEG C--the heating temperatures of 725 DEG C, and curved surface cover-plate glass is heated to 635 DEG C--and after 655 DEG C, rotary-tray drives and enters next station; Rotary-tray, by the temperature measuring equipment in body of heater, adjusts rotating speed according to the temperature in body of heater in good time.
Beneficial effect: mould adopts heat-resistance stainless steel to make, and heat absorption is fast, and produce thermal radiation to glass from bottom, be conducive to glass heats synthesis type, 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 the rotating disk of heating zone 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: loading and unloading station, several heating stations, shaping station and the station that cools.Loading and unloading station is that top half is opened wide, and picks and places glass to facilitate.The stove silk of heating zone is arranged on the top of " N " type burner hearth, and the bottom of stove silk is provided with the radiator tube of accumulation of heat equilibrium temperature, the heating temperatures radiator tube of stove silk, then has radiator tube to heat glass, and temperature adopts thermopair and temperature controller to control.In furnace chamber, surrounding all adopts lagging material to be incubated.The rotating disk upper bottom portion of bottom has lagging material, and rotating disk arranges several flat platforms by certain interval, and for placing former, rotating disk rotates under the drive of motor, a station of at every turn advancing.
On the passage of described heating zone, top is fixed, the bottom of circular ring path and " " body of heater of type is unconnected to N, and beat that can be certain rotates.
Described radiator tube adopts Heat-Resisting Stainless Steel Tube to make, and the diameter of radiator tube is 10-20mm, and wall thickness is 2mm.
Described mould adopts heat-resistance stainless steel, model 310S.
Curved surface mobile phone thermoforming stove of the present invention adopts heat-resistance stainless steel radiator tube, and be placed in the bottom of burner hearth stove silk, some radiator tubes paralleled connect side by side and form, form corrugated radiating surface, during radiation, define a cross one another radiating surface, the speed of heat trnasfer is fast; Radiator tube accepts the stove silk heating of different units, and radiator tube is heated evenly, and effectively decrease all around temperature difference in stove, heats is good.
Heat treated: by plane mobile phone glass thickness 0.2--0.7mm good for finishing impression surface cleaning, lie in the female stainless steel mould on the circle ring disk rotated by beat at upper and lower material level, glass is sequentially transferred in stove by beat motion and heats, in-furnace temperature is at 700--725 DEG C, temperature is pressed station successively and is raised, every district raises 5-10 DEG C, there are several heating zone, the residence time of each station and heat-up time can adjust, when glass motion arrives last heating station, glass is heated to 635-655 DEG C.
