The vertical lateral surface of mould inside it carries out sensing heating, and the Xu Leng station is used to cool to mould and glass,
The cooling station is used to further cool Xu Lenghou glass.
Preferably, the wide and high of the radial section outside dimension of the hollow copper tubing be between 8~10mm, hollow copper tubing
Wall thickness is 1~2.3mm, and the gap of adjacent two circle is 1~2.5mm between the hollow copper tubing of upper and lower coiling multiturn formation copper band.One
In kind specific embodiment, purpose product is the curved square glass in four sides, including the mould of upper and lower mould and mold insert is cuboid
Type, copper band is wound on four vertical side peripheries of mould, thus the horizontal cross-section of copper band is generally rectangular shaped, and the copper band includes
Vertically around the hollow copper tubings for restricting 8 circles, the radial section outside dimension of the hollow copper tubing is wide 10mm and high 8mm, hollow copper
The wall thickness of pipe is 2mm, and the gap of adjacent two circle is 2mm between the hollow copper tubing of upper and lower coiling multiturn formation copper band.The utility model
The height of middle copper band and mould total height are essentially identical, and the height of upper die and lower die is all in 40mm or so.The hollow copper tubing of copper band
Interior water flowing, copper band are connected with High-frequency machine and are used to carry out sensing heating to mould.In the utility model, the forming temperature of glass periphery
During less than 690 DEG C, it is difficult to reach due molding effect, and can be right when the forming temperature of glass periphery is higher than 740 DEG C
Glass is well on shaping, if but glass periphery temperature it is too high when cause the temperature in glass centre position also to reach glass unavoidably
Softening point, thus a problem that to avoid glass centre position from sags and crests and impressing occur, typically control in the utility model
The forming temperature of glass periphery processed is not higher than 740 DEG C.During shaping, the temperature of center of glass can be less than 650 DEG C, but medium temperature
The probability of too high a problem that then forming sags and crests and impressing is higher.In general, peripheral temperature during shaping and center
It is the most suitable during 100~150 DEG C of temperature difference.
The first pushing ram 5 is used to the mould for carrying glass being pushed into pre- thermal engineering station in Fig. 4, and the second pushing ram 6 is used for
The mould that preheating is completed in pre- thermal engineering station is pushed into shaping station, Xu Leng station and cooling station successively.
Technological process when device described in the utility model is used for heat-bending glass is as follows：
1) preheating station, when mould is advanced to station 1, mould reaches mould by heating wolfram steel plate up and down by heat transfer
Between surface temperature is 430 DEG C to 460 DEG C.Wherein, heating wolfram steel plate is molded by contacting die surface without applying up and down
Pressure, transmit heat on mould, it is therefore an objective to mould is integrally heated and reach certain temperature (being less than glass transition temperature), to add
Thermoforming station 2 can short time mould and prepare；
2) hot briquetting station, when mould is pushed to station 2, whole mould is ejected cylinder (upper top gas cylinder) top and added to copper band
Thermal potential is put, and middle cylinders 23, which are pushed down mold insert and fixed by glass board material, not to be moved, and now copper band produces heat after being powered, and heat is from mould
Centre is delivered to around tool, when the temperature that (peripheral temperature) detects when mould molding position reaches 690 DEG C to 740 DEG C, mould
At 560 DEG C to 630 DEG C, two side cylinders 24 started to push and mould molding is reached shaping position medium temperature this when.
Wherein, copper band produces magnetic field after being powered, and magnetic field produces heat, and heat transfer mode is that purpose was to make from mould four weeks to centre
Four sides bent products bent portion reach softening point and are molded, centre without bending part low temperature without produce sags and crests with
Impressing.The glass product brightness that such hot bending is prepared is high thus process sweeps time consuming, product center section after can reducing
Sags and crests and impressing are not had and improves yield, and hot bending processing efficiency is fast and can produce in enormous quantities；
3) first Xu Leng station 3, first Xu Leng station is pushed to after mould molding, the upper and lower wolfram steel plate temperatures of Xu Lengzhan
It is arranged between 560 DEG C to 630 DEG C, Xu Leng is started to mould, wherein, by wolfram steel plate transition temperature above and below setting so as to slowly
Cooling down high-temperature mould, it is therefore an objective to make glass have a process slowly cooled down so as to reduce stress caused by inside glass to improve
Strength of glass, in case product causes glass fragmentation faced phenomenon, and this Xu Leng work during low temperature is reduced rapidly to by high temperature
Station is to adjust the essential station of glass flatness；
4) second Xu Leng station 3, mould is pushed to second Xu Leng station from first Xu Leng station, above and below the station
Heating wolfram steel plate temperature is arranged between 440 DEG C to 560 DEG C, to second of Xu Leng of mould, wherein, by setting wolfram steel plate up and down
Transition temperature is so as to slowly cooling down high-temperature mould, it is therefore an objective to makes glass have a process slowly cooled down to reduce inside glass
Stress is to improve strength of glass；The purpose for setting two Xu Leng station is also to reduce glass cooling velocity, avoids inside glass from producing
Give birth to substantial amounts of stress and influence its performance.
5) two quick cooling stations 4, when mould is pushed to station 4, it is not necessary to which temperature is set, and mould is now by being connected with
The coldplate of cooling water is cooled down, wherein, mould is quickly cooled down by the coldplate up and down for being connected with cooling water, Yin Bo
Glass will not change below 400 DEG C, thus can quickly cool down to improve processing efficiency；
6) mould is pushed to outside furnace chamber, picks and places glass product.
Table 1 is the temperature and pressure data of each station in forming process.Wherein, in station 2 is molded, side cylinder 24 is to upper
The pressure of the surrounding of lower mould is less than pressure of the middle cylinders 23 to glass intermediate region, in case glass moves in forming process
Position.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
