Embodiment
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of biplate enters stove glass tempering method, the tempering process of glass is realized based on annealing furnace, annealing furnace comprises process furnace, shaping area and cooling zone, glass process furnace, between shaping area and cooling zone by roller conveyor transmission, shaping area is provided with the forming ring with the mating shapes of glass, the width of forming ring is 45 ± 3mm, the method utilizes biplate die and biplate punch, carries out tempering process simultaneously, comprise the following steps two sheet glass:
(1) by two sheet glass in process furnace by glass heats to 650 DEG C ~ 720 DEG C;
(2) after glass is heated to setting-up time in process furnace, in process furnace light eye and plug for outlet optical fiber control under with 1500mm/s
2acceleration quick tapping, the transmission of the section of coming out of the stove SECTOR-SEVEN from light eye place need with front end process furnace in transmit and separate, two sections of acceleration are divided to come out of the stove, simultaneously, glass is located in shaping area by station-keeping system, and station-keeping system comprises cylinder and backstay, and cylinder is arranged on below roller conveyor, backstay connects the piston rod of cylinder, and cylinder drives backstay to move up and down.Concrete position fixing process is: backstay extend out to 5 ± 1mm above roller conveyor, accurately locate for realizing glass, alleviate the collision dynamics of glass and backstay, after glass touches backstay with the speed of 120mm/s ~ 150mm/s, glass stop motion, backstay is retracted to below roller conveyor simultaneously, and then suppress, biplate die is with acceleration 2000mm/s
2to rise to below roller conveyor in 0.4 second above roller conveyor and jack-up glass, and stop after continuing to rise, biplate punch drops to apart from 2 ~ 3mm place stopping above glass simultaneously, makes glass ware forming.For improving optical quality of glazings, reduce the duration of contact of glass and delivery roll, it is optimum regime with regard to jack-up glass that biplate die must to be advanced to biplate die when glass has just contacted backstay start time, and namely biplate die must have jack-up in advance to control (with the height distance of the die die face of biplate die and delivery roll horizontal plane for reference mark).
(3) pattern 1: to automobile triangular window, the small sphere of exterior rearviews such as side window glass, the triangular glass of little sagitta and most of complex curvatures side window, when rear side and the process of triangular glass tempering, biplate punch rises, biplate die drops to close to roller conveyor, and pause 0 ~ 0.5 second, after treating that roller conveyor accelerates, biplate die declines, glass is made to drop down onto on roller conveyor, with top speed 1500mm/s, glass is delivered to cooling zone by roller conveyor, dry in 7 seconds to glass, it is made to be cooled to 300 ± 50 DEG C, and then cool further through the deceleration road of 6 meters, , glass sectional deceleration transmission when being namely transferred to the 6th air grid in glass rear end, geard-down speed regulates automatically with the tempering setting-up time of glass.When faceplate is transferred to air grid end, glass accelerates to enter cooling zone, to ensure the tempering time consistency of glass front and back end, reduces the productive temp time, in order to avoid affect next sheet glass to enter the tempering stage simultaneously.
Pattern 2: when requiring high and glass tempering process that specification is larger to the profiles such as automobile skylight glass, the goodness of fit, biplate punch, under the effect of vacuum generator, holds glass, and meanwhile, biplate die is with acceleration 2000mm/s
2drop to below roller conveyor, biplate punch carries glass and rises to setting height, forming ring enters immediately below glass, biplate punch drops to desired location, and vacuum generator cuts out, and glass falls under gravity on forming ring, with top speed 1500mm/s, glass is delivered to cooling zone by roller conveyor, glass was dried for 7 ± 3 seconds, makes it be cooled to 300 ± 50 DEG C, and then cool further through the deceleration road of 6 meters.
Tempering terminates, and upper air grid is closed, and glass blows afloat and is attached to air grid, and forming ring enters shaping area and connects next sheet glass, goes up air grid simultaneously and closes, and glass drops on contact pin shuttle (contact pin shuttle and forming ring belong to one two stations);
Instantly, when a sheet glass carries out tempering, front sheet glass enters into zone of transition; After tempering terminates, the little air grid in zone of transition bottom is opened and is blown afloat by front sheet glass, and glass is attached in zone of transition top roller; When forming ring goes to connect another sheet glass again, the little air grid in zone of transition bottom is closed, and glass drops on zone of transition delivery roll, enters cooling zone cooling.This programme conveniently biplate enters the transition bottom sheet of stove pattern, and is conducive to the not closed toughened glass of air grid.
In the present invention, biplate die making method is as follows: enter sheet direction according to glass, by the die position 90-degree rotation of original monolithic die, longitudinally exploitation, namely die position long limit and glass to enter sheet direction vertical, two die positions are arranged side by side, and two die positions are completely the same, do not allow error, form biplate die.The making of biplate punch (as shown in Figure 2) is the same.When biplate punch and biplate die are proofreaded, between two moulds, require laminating.
When forming ring and biplate punch are proofreaded, biplate punch and forming ring require to fit.During for refractive power substandard product, during for biplate punch problem, carry out biplate punch milling profile.
For below width 450mm, the glass that length is less than 900mm adopts biplate to enter stove pattern; According to the outer forming furnace maximum productivity of currently available products structure and stove, filter out and meet biplate and enter stove product.The outer forming furnace device structure of existing stove, it is wide that maximum effective width can be 1100mm.Currently available products structure, most of skylight glass dimension width is at below 450mm.Be 1100mm, product size 450mm according to knowhow equipment effective width, two panels product size is added together is 900mm, also has 200mm space, this 200mm space is used for the activity space of the location in the middle of two sheet glass.And 450mm width skylight product, side window product account for 70% of all products, practicality of the present invention is stronger.
