Description
Technical field
The invention belongs to the technical fields of the reshaping of first type glass.
Background technique
In the past, in the case where carrying out bending machining to windshield, following processing method is mainly used: by windshield
On the bending mould for being cut into defined size shape, and being positioned in the heating furnace of atmospheric environment, it is heated to energy
The softening temperature for enough carrying out the glass plate of bending forming is (different because of glass material, but generally 550 DEG C~700 DEG C left sides
It is right), it is firmly pulled by being self-possessed or clamping plate glass two sides as a result, plate glass is made to be deformed into the shape along bending mould
Shape.
However, existing heating furnace more typically heats glass from bottom to top, cause glass heating surface uneven,
Thus cause the time of heating to increase, waste the more energy, processing efficiency is low；In addition, being needed using self weight bending
To time it is longer, efficiency is lower；And since the glass after heating is relatively soft, plate glass two sides are clamped using clamping plate and are pulled at
Dynamic method, can make the discontinuity of glass, and the part stress of glass clamping is larger, it may appear that the case where flattening, influence curved
The qualification rate of bent glass production, reduces the processing efficiency of glass.
